20250097632
This application claims priority to Korean Patent Application No. 10-2023-0123002 filed in the Republic of Korea on Sep. 15, 2023, the entire contents of which is hereby expressly incorporated by reference into the present application.
The present disclosure relates to a sound apparatus and a vehicular apparatus including the same.
Vehicles include a sound apparatus which outputs a sound based on an audio signal output from a multimedia device such as a car audio device. For example, the sound apparatus applied to vehicles can include a front speaker and a rear speaker, which are configured as a coil type.
However, a sound apparatus in the vehicles can be limited when outputting a realistic sound or stereo sound of a multichannel through the front speaker and the rear speaker to limitations of the coil type device. Further, in the sound apparatus in vehicles, in a case where the number of speakers are increased, a stereo sound can be output, but due to a size of the speakers based on the coil type device and a limitation of a space in vehicles, there is a limitation in increasing the number of speakers so that a realistic sound or stereo sound may not be provided using the coil type device.
The inventors of the present disclosure have recognized the problems and disadvantages of the related art and have performed extensive research and experiments for enhancing sound characteristics and/or sound pressure level characteristics of a sound apparatus for vehicles. Based on the extensive research and experiments, the inventors have invented an improved sound apparatus and an improved vehicular apparatus including the same, which can enhance sound characteristics and/or sound pressure level characteristics.
One or more aspects of the present disclosure are directed to providing a sound apparatus and a vehicular apparatus including the same, which can enhance sound characteristics and/or sound pressure level characteristics.

Other systems, methods, features and advantages will be, or will become, apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the present disclosure, and be protected by the following claims. Nothing in this section should be taken as a limitation on those claims. Further aspects and advantages are discussed below in conjunction with aspects of the disclosure.
It is to be understood that both the foregoing description and the following description of the present disclosure are example and explanatory and are intended to provide further explanation of the disclosure as claimed.
The accompanying drawings, which are included to provide a further understanding of the disclosure, are incorporated in and constitute a part of this disclosure, illustrate aspects and embodiments of the disclosure and together with the description serve to explain principles of the disclosure.
Throughout the drawings and the detailed description, unless otherwise described, the same drawing reference numerals should be understood to refer to the same elements, features, and structures. The sizes, lengths, and thicknesses of layers, regions and elements, and depiction of thereof can be exaggerated for clarity, illustration, and/or convenience.
Reference is now made in detail to aspects of the present disclosure, examples of which can be illustrated in the accompanying drawings. In the following description, when a detailed description of well-known functions, structures or configurations can unnecessarily obscure aspects of the present disclosure, a detailed description of such known functions or configurations can have been omitted for brevity. Further, repetitive descriptions can be omitted for brevity. The progression of processing steps and/or operations described is a non-limiting example.
The sequence of steps and/or operations is not limited to that set forth herein and can be changed to occur in an order that is different from an order described herein, with the exception of steps and/or operations necessarily occurring in a particular order. In one or more examples, two operations in succession can be performed substantially concurrently, or the two operations can be performed in a reverse order or in a different order depending on a function or operation involved.
Unless stated otherwise, like reference numerals can refer to like elements throughout even when they are shown in different drawings. In one or more aspects, identical elements (or elements with identical names) in different drawings can have the same or substantially the same functions and properties unless stated otherwise. Names of the respective elements used in the following explanations are selected only for convenience and can be thus different from those used in actual products.
Advantages and features of the present disclosure, and implementation methods thereof, are clarified through the aspects described with reference to the accompanying drawings. The present disclosure may, however, be embodied in different forms and should not be construed as limited to the example aspects set forth herein. Rather, these example aspects are examples and are provided so that this disclosure can be thorough and complete to assist those skilled in the art to understand the inventive concepts without limiting the protected scope of the present disclosure.
Shapes (e.g., sizes, lengths, widths, heights, thicknesses, locations, radii, diameters, and areas), dimensions, ratios, angles, numbers, and the like disclosed herein, including those illustrated in the drawings, are merely examples, and thus, the present disclosure is not limited to the illustrated details. Any implementation described herein as an “example” is not necessarily to be construed as preferred or advantageous over other implementations. It is, however, noted that the relative dimensions of the components illustrated in the drawings are part of the present disclosure.
Where a term like “comprise,” “have,” “include,” “contain,” “constitute,” “made of,” “formed of,” or the like is used with respect to one or more elements, one or more other elements can be added unless a term such as “only” or the like is used. The terms used in the present disclosure are merely used in order to describe example aspects, and are not intended to limit the scope of the present disclosure. The terms of a singular form can include plural forms unless the context clearly indicates otherwise.
The word “exemplary” is used to mean serving as an example or illustration, unless otherwise specified. Aspects are example aspects. “Aspects,” “examples,” and the like should not be construed as preferred or advantageous over other implementations. An aspect, an example, an example aspect, or the like can refer to one or more aspects, one or more examples, one or more example aspects, or the like, unless stated otherwise. Further, the term “can” encompasses all the meanings of the term “may.”
In one or more aspects, unless explicitly stated otherwise, element, feature, or corresponding information (e.g., a level, range, dimension, size, or the like) is construed to include an error or tolerance range even where no explicit description of such an error or tolerance range is provided. An error or tolerance range can be caused by various factors (e.g., process factors, internal or external impact, noise, or the like). In interpreting a numerical value, the value is interpreted as including an error range unless explicitly stated otherwise.
In describing a positional relationship when the positional relationship between two parts (e.g., layers, films, regions, components, sections, or the like) is described, for example, using “on,” “upon,” “on top of,” “over,” “under,” “above,” “below,” “beneath,” “near,” “close to,” “adjacent to,” “beside,” “next to,” “at or on a side of,” or the like, one or more other parts can be located between the two parts unless a more limiting term, such as “immediate(ly),” “direct(ly),” or “close(ly),” is used. For example, where a structure is described as being positioned “on,” “upon,” “on top of,” “over,” “under,” “above,” “below,” “beneath,” “near,” “close to,” “adjacent to,” “beside,” “next to,” “at or on a side of,” or the like another structure, this description should be construed as including a case in which the structures contact each other as well as a case in which one or more additional structures are disposed or interposed therebetween. Furthermore, the terms “front,” “rear,” “back,” “left,” “right,” “top,” “bottom,” “downward,” “upward,” “upper,” “lower,” “up,” “down,” “column,” “row,” “vertical,” “horizontal,” and the like refer to an arbitrary frame of reference.
Spatially relative terms, such as “below,” “beneath,” “lower,” “on,” “above,” “upper” and the like, can be used to describe a correlation between various elements (e.g., layers, films, regions, components, sections, or the like) as shown in the drawings. The spatially relative terms are to be understood as terms including different orientations of the elements in use or in operation in addition to the orientation depicted in the drawings. For example, if the elements shown in the drawings are turned over, elements described as “below” or “beneath” other elements would be oriented “above” other elements. Thus, the term “below,” which is an example term, can include all directions of “above” and “below.” Likewise, an example term “above” or “on” can include both directions of “above” and “below.”
In describing a temporal relationship, when the temporal order is described as, for example, “after,” “subsequent,” “next,” “before,” “preceding,” “prior to,” or the like, a case that is not consecutive or not sequential can be included and thus one or more other events can occur therebetween, unless a more limiting term, such as “just,” “immediate(ly),” or “direct(ly),” is used.
The terms, such as “below,” “lower,” “above,” “upper” and the like, can be used herein to describe a relationship between element(s) as illustrated in the drawings. It will be understood that the terms are spatially relative and based on the orientation depicted in the drawings.
It is understood that, although the terms “first,” “second,” or the like can be used herein to describe various elements (e.g., layers, films, regions, components, sections, or the like), these elements should not be limited by these terms, for example, to any particular order, sequence, precedence, or number of elements. These terms are used only to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present disclosure. Furthermore, the first element, the second element, and the like can be arbitrarily named according to the convenience of those skilled in the art without departing from the scope of the present disclosure. For clarity, the functions or structures of these elements (e.g., the first element, the second element and the like) are not limited by ordinal numbers or the names in front of the elements. Further, a first element can include one or more first elements. Similarly, a second element or the like can include one or more second elements or the like.
In describing elements of the present disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” or the like can be used. These terms are intended to identify the corresponding element(s) from the other element(s), and these are not used to define the essence, basis, order, or number of the elements.
For the expression that an element (e.g., layer, film, region, component, section, or the like) is described as “connected,” “coupled,” “attached,” “adhered,” or the like to another element, the element can not only be directly connected, coupled, attached, adhered, or the like to another element, but also be indirectly connected, coupled, attached, adhered, or the like to another element with one or more intervening elements disposed or interposed between the elements, unless otherwise specified.
For the expression that an element (e.g., layer, film, region, component, section, or the like) “contacts,” “overlaps,” or the like with another element, the element can not only directly contact, overlap, or the like with another element, but also indirectly contact, overlap, or the like with another element with one or more intervening elements disposed or interposed between the elements, unless otherwise specified.
The phrase that an element (e.g., layer, film, region, component, section, or the like) is “provided in,” “disposed in,” or the like in another element can be understood as that at least a portion of the element is provided in, disposed in, or the like in another element, or that the entirety of the element is provided in, disposed in, or the like in another element. The phase that an element (e.g., layer, film, region, component, section, or the like) “contacts,” “overlaps,” or the like with another element can be understood as that at least a portion of the element contacts, overlaps, or the like with a least a portion of another element, that the entirety of the element contacts, overlaps, or the like with a least a portion of another element, or that at least a portion of the element contacts, overlaps, or the like with the entirety of another element.
The terms such as a “line” or “direction” should not be interpreted only based on a geometrical relationship in which the respective lines or directions are parallel or perpendicular to each other. Such terms can mean a wider range of lines or directions within which the components of the present disclosure can operate functionally. For example, the terms “first direction,” “second direction,” and the like, such as a direction parallel or perpendicular to “x-axis,” “y-axis,” or “z-axis,” should not be interpreted only based on a geometrical relationship in which the respective directions are parallel or perpendicular to each other, and can be meant as directions having wider directivities within the range within which the components of the present disclosure can operate functionally.
The term “at least one” should be understood as including any and all combinations of one or more of the associated listed items. For example, each of the phrases of “at least one of a first item, a second item, or a third item” and “at least one of a first item, a second item, and a third item”, can represent (i) a combination of items provided by one or more of the first item, the second item, and the third item or (ii) only one of the first item, the second item, and the third item.
The expression of a first element, a second elements, “and/or” a third element should be understood to encompass one of the first, second, and third elements, as well as any and all combinations of the first, second and third elements. By way of example, A, B and/or C encompass only A; only B; only C; any of A, B, and C (e.g., A, B, or C); some combinations of A, B, and C (e.g., A and B; A and C; or B and C); and all of A, B, and C. Furthermore, an expression “A/B” can be understood as A and/or B. For example, an expression “A/B” can refer to only A; only B; A or B; or A and B.
In one or more aspects, the terms “between” and “among” can be used interchangeably simply for convenience unless stated otherwise. For example, an expression “between a plurality of elements” can be understood as among a plurality of elements. In another example, an expression “among a plurality of elements” can be understood as between a plurality of elements. In one or more examples, the number of elements can be two. In one or more examples, the number of elements can be more than two. Furthermore, when an element (e.g., layer, film, region, component, sections, or the like) is referred to as being “between” at least two elements, the element can be the only element between the at least two elements, or one or more intervening elements can also be present.
In one or more aspects, the phrases “each other” and “one another” can be used interchangeably simply for convenience unless stated otherwise. For example, an expression “different from each other” can be understood as different from one another. In another example, an expression “different from one another” can be understood as different from each other. In one or more examples, the number of elements involved in the foregoing expression can be two. In one or more examples, the number of elements involved in the foregoing expression can be more than two.
In one or more aspects, the phrases “one or more among” and “one or more of” can be used interchangeably simply for convenience unless stated otherwise.
The term “or” means “inclusive or” rather than “exclusive or.” For example, unless otherwise stated or clear from the context, the expression that “x uses a or b” means any one of natural inclusive permutations. For example, “a or b” can mean “a,” “b,” or “a and b.” For example, “a, b or c” can mean “a,” “b,” “c,” “a and b,” “b and c,” “a and c,” or “a, b and c.”
Features of various aspects of the present disclosure can be partially or entirely coupled to or combined with each other, can be technically associated with each other, and can be operated, linked, or driven together in various ways. Aspects of the present disclosure can be implemented or carried out independently from each other, or can be implemented or carried out together in a co-dependent or related relationship. In one or more aspects, the components of each apparatus according to various aspects of the present disclosure can be operatively coupled and configured.
Unless otherwise defined, the terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example aspects belong. It should be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning, for example, consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense, unless expressly defined otherwise herein.
The terms used herein have been selected as being general in the related technical field; however, there can be other terms depending on the development and/or change of technology, convention, preference of technicians, and so on. Therefore, the terms used herein should not be understood as limiting technical ideas, but should be understood as examples of the terms for describing example aspects.
Further, in a specific case, a term can be arbitrarily selected by an applicant, and in this case, the detailed meaning thereof is described herein. Therefore, the terms used herein should be understood based on not only the name of the terms, but also the meaning of the terms and the content hereof.
Here, “X-axis direction”, “Y-axis direction” and “Z-axis direction” should not be construed by a geometric relation only of a mutual vertical relation and can have broader directionality within the range that elements of the present disclosure can act functionally.
In the following description, various example aspects of the present disclosure are described in detail with reference to the accompanying drawings. With respect to reference numerals to elements of each of the drawings, the same elements can be illustrated in other drawings, and like reference numerals can refer to like elements unless stated otherwise. The same or similar elements can be denoted by the same reference numerals even though they are depicted in different drawings.
In addition, for convenience of description, a scale, dimension, size, and thickness of each of the elements illustrated in the accompanying drawings can be different from an actual scale, dimension, size, and thickness, and thus, aspects of the present disclosure are not limited to a scale, dimension, size, and thickness illustrated in the drawings.

For example, the vehicle interior material 130 can vibrate by a vibration of the first enclosure 311 based on the sound (or sound pressure level or sound wave) generated in the internal space 313 of the enclosure 310 to generate (or output) a sound.
According to an embodiment of the present disclosure, the internal space 313 of the enclosure 310 can include a first space 313a and a second space 313b.
The vibration member 331 can be disposed at the internal space 313 of the enclosure 310.

For example, the first vibration apparatus 333 and the second vibration apparatus 335 can be disposed with the vibration member 331 therebetween.
The vibration member 331 can be disposed or configured at a region between the first enclosure 311 and the second enclosure 312 of the enclosure 310. The vibration member 331 can be configured to divide the internal space 313 of the enclosure 310 into the first space 313a and the second space 313b. For example, the internal space 313 of the enclosure 310 can be divided into the first space 313a and the second space 313b by the vibration member 331. For example, the first space 313a of the internal space 313 can be provided at a region between the first enclosure 311 of the enclosure 310 and the vibration member 331 and can be covered by the vibration member 331. The second space 313b of the internal space 313 can be provided at a region between the second enclosure 312 of the enclosure 310 and the vibration member 331 and can be covered by the vibration member 331.
According to an embodiment of the present disclosure, the first vibration apparatus 333 and the second vibration apparatus 335 can be at different spaces in the internal space 313 of the enclosure 310. For example, the first vibration apparatus 333 can be at the first space 313a. For example, the second vibration apparatus 335 can be at the second space 313b.
The first space 313a can be between the sound generating module 330 and the first enclosure 311. For example, the first space 313a can be between the first surface of the sound generating module 330 and the first enclosure 311. The first space 313a can be between the first vibration apparatus 333 and the first enclosure 311. The second space 313b can be between the sound generating module 330 and the second enclosure 312. For example, the second space 313b can be between the second surface which is different from (or opposite to) the first surface of the sound generating module 330 and the second enclosure 312. The second space 313b can be between the second vibration apparatus 335 and the second enclosure 312. For example, the internal space 313 can be a gap space, an air space, a vibration space, a sound space, a sound box, or a sealing space, or the like, but embodiments of the present disclosure are not limited thereto.
The sound generating module 330 can generate a sound pressure level (or sound or sound wave) in the internal space 313 of the enclosure 310 to vibrate the enclosure 310 and can vibrate the vibration object or the vehicle interior material 130 based on a vibration of the enclosure 310. For example, the sound generating module 330 can be configured to vibrate the first enclosure 311 of the enclosure 310 to vibrate the vibration object or the vehicle interior material 130. For example, the sound generating module 330 can generate the sound pressure level (or sound or sound wave) in the internal space 313 of the enclosure 310 to vibrate the first enclosure 311 and can vibrate the vibration object or the vehicle interior material 130 based on a vibration of the first enclosure 311.
According to an embodiment of the present disclosure, the first enclosure 311 can include an opening part 310o.
The opening part 310o can be configured to pass through (or vertically pass through) the first enclosure 311 along a thickness direction Z (or a vertical direction) of the enclosure 310. The opening part 310o can be connected to (or communicate with) the internal space 313. For example, the opening part 310o can be configured to decrease an air pressure of the internal space 313 of the enclosure 310. For example, the opening part 310o can be connected to the first space 313a. The opening part 310o can be configured to decrease an air pressure of the first space 313a of the first enclosure 311 or an air pressure of the first space 313a provided between the vibration member 331 and the first enclosure 311. Therefore, a band of the low-pitched sound band can expand, and thus, a sound characteristic of the low-pitched sound band can be improved. For example, because a pressure (or air pressure) of the first space 313a is reduced by the opening part 310o, the amount of displacement (or a bending force) of the first vibration apparatus 333 disposed between the vibration member 331 and the first enclosure 311 can increase, and thus, a band of the low-pitched sound band can expand, thereby enhancing sound characteristics and/or sound pressure level characteristics of the low-pitched sound band. Accordingly, a sound characteristic (or a sound pressure level) of the low-pitched sound band generated based on a vibration of the first vibration apparatus 333 and/or the second vibration apparatus 335 can be improved.
According to an embodiment of the present disclosure, the opening part 310o can be disposed to correspond to a center portion of the sound generating module 330. For example, the opening part 310o can be disposed to correspond to the vibration apparatus 333 and 335. For example, the opening part 310o can be disposed to correspond to a center portion of the first vibration apparatus 333 and the second vibration apparatus 335. For example, the opening part 310o can be disposed to correspond to a center portion of each of the first vibration apparatus 333 and the second vibration apparatus 335. For example, the internal space 313 of the enclosure 310 can include a space connected to the opening part 310o. For example, the internal space 313 of the enclosure 310 can include the first space 313a connected to the opening part 310o.
According to an embodiment of the present disclosure, the opening part 310o can have a size which is smaller than the first vibration apparatus 333.

For example, the opening part 310o can include a line shape having a size (or a length) which is smaller than the first vibration apparatus 333 disposed at the vibration member 331. For example, the opening part 310o can be a hole, a slot, or a slit, but embodiments of the present disclosure are not limited thereto. For example, the opening part 310o can be a sound emission portion, a first sound emission port, a sound output part, a sound output port, a sound output hole, a duct hole, or a vent hole, but embodiments of the present disclosure are not limited thereto.
The opening part 310o can be a space where a sound wave generated based on a vibration of the sound generating module 330 is propagated (or transferred) to the interior space IS of the vehicle 10. For example, a vibration of the sound generating module 330 can be transferred to the vibration object or the interior space IS of the vehicle 10 through the opening part 310o. For example, a sound wave (or sound) based on the vibration of the sound generating module 330 can be transferred (or output or emitted) to the interior space IS of the vehicle 10 through the opening part 310o. Accordingly, a vibration width (or a displacement width) of the vibration member 331 based on the vibration of the sound generating module 330 can increase, and thus, sound characteristics and/or sound pressure level characteristics generated based on a vibration of the vibration member 331 can be enhanced.
The first enclosure 311 including the opening part 310o can be disposed closer to the vehicle interior material 130 than the second enclosure 312. For example, the first enclosure 311 including the opening part 310o can be disposed closer to the vehicle interior material 130 than the second enclosure 312. Accordingly, a sound generated based on vibrations of one or more of the first vibration apparatus 333 and the second vibration apparatus 335 can be output to the interior space IS of the vehicle 10, and thus, a sound including the low-pitched sound band can be output to the interior space IS of the vehicle 10.
The first enclosure 311 can include a slope surface (or an inclined surface) 311s and an inner lateral surface 311i. The slope surface 311s can be configured to be inclined between the opening part 310o and the inner lateral surface 311i of the first enclosure 311. The slope surface 311s can be configured to guide a sound, generated based on a vibration of the sound generating module 330, to the interior space IS of the vehicle 10. Accordingly, the sound generated based on the vibration of the sound generating module 330 can be output to the interior space IS of the vehicle 10, and sound characteristics and/or sound pressure level characteristics of a sound including the low-pitched sound band can be more enhanced. For example, the slope surface 311s can be a guide surface or a sound guide surface, but embodiments of the present disclosure are not limited thereto.

For example, the second enclosure 312 can be configured to surround the second surface of the sound generating module 330.
The sound apparatus 30 according to an embodiment of the present disclosure can further include a coupling member 320. The coupling member 320 can be configured to connect or couple the vibration member 331 and the enclosure 310 to each other. For example, the coupling member 320 can be between the periphery portion of the vibration member 331 and the enclosure 310.

In the sound apparatus 30 according to an embodiment of the present disclosure, a vibration of the vibration member 331 can be transferred to the vibration member 331 without loss due to the integrated structure (or one body structure) of the vibration member 331 and the vibration apparatus 333 and 335, and thus, a sound pressure level characteristic of a sound generated by the vibration of the vibration member 331 can be enhanced. Furthermore, in the sound apparatus 30 according to an embodiment of the present disclosure, because a separate adhesive member or a separate intermediate member for coupling (or adhering) the vibration apparatus 333 and 335 and the vibration member 331 to each other is omitted, a manufacturing process can be simplified and a manufacturing cost can be reduced.
With reference to
The vibration generator 1310 can include a piezoelectric material having a piezoelectric characteristic. The vibration generator 1310 can vibrate (or displace or drive) a vibration member (or a vehicle interior material) based on a vibration (or displacement or driving) of the piezoelectric material by an electric signal (or a voice signal or a sound signal) applied to the piezoelectric material. For example, the vibration generator 1310 can alternately repeat contraction and/or expansion by a piezoelectric effect (or a piezoelectric characteristic) to vibrate (or displace or drive).

For example, the first electrode part 1311b can be disposed (or configured) at at least a portion of the first surface 1311s1 of the vibration part 1311a. For example, the first electrode part 1311b can be configured to have a pattern shape or a line shape corresponding to the at least the portion of the first surface 1311s1 of the vibration part 1311a and can be connected to (or in contact with) or directly connected to (or in contact with) the at least the portion of the first surface 1311s1 of the vibration part 1311a.
The second electrode part 1311c can be disposed at a second surface (or a lower surface or a rear surface) 1311s2 which is opposite to or different from the first surface 1311s1 of the vibration part 1311a. The second electrode part 1311c can have a same size as the vibration part 1311a, or can have a size which is smaller than the vibration part 1311a.

The vibration part 1311a can alternately and repeatedly contract and/or expand by an inverse piezoelectric effect based on a driving signal applied to the first electrode part 1311b and the second electrode part 1311c from the outside to vibrate. For example, the vibration part 1311a can vibrate in a vertical direction (or thickness direction) and in a planar direction by the signal applied to the first electrode part 1311b and the second electrode part 1311c. The vibration part 1311a can be displaced (or vibrated or driven) by contraction and/or expansion of the planar direction, thereby improving a vibration characteristic including sound characteristics and/or sound pressure level characteristics of the vibration generator 1310.

For example, the first surface of the vibration generating part 1311 adjacent to the vibration member 331 can be accommodated (or inserted) into a portion of the vibration member 331. For example, one of the first electrode part 1311b and the second electrode part 1311c can be accommodated (or inserted) into the portion of the vibration member 331. For example, the first electrode part 1311b of the first electrode part 1311b and the second electrode part 1311c can be accommodated (or inserted) into the portion of the vibration member 331.

For example, when the one or more holes 331o is disposed at a position farther away from each of the vibration apparatuses 333 and 335, sound characteristics and/or sound pressure level characteristics of a low-pitched sound band can be more improved.
According to an embodiment of the present disclosure, the one or more holes 331o can be configured at the vibration member 331 adjacent to the vibration apparatuses 333 and 335 with the vibration apparatuses 333 and 335 therebetween. For example, the vibration member 331 can include a first periphery region adjacent a first lateral surface of each of the vibration apparatuses 333 and 335 and a second periphery region, which is opposite to a second side opposite to a first side, of each of the vibration apparatuses 333 and 335. For example, with respect to a first direction X, the vibration member 331 can include the first periphery region, a vibration region, and the second periphery region. For example, in the vibration member 331, each of the first and second periphery regions can be a hole region or a non-arrangement region of each of the vibration apparatuses 333 and 335, and the vibration region can be an arrangement region (or a disposition region) of the vibration apparatuses 333 and 335. For example, the one or more holes 331o can be configured in each of the first periphery region and the second periphery region of the vibration member 331 to have a symmetric structure (or a horizontal symmetric structure or a left-right symmetric structure) or an asymmetric structure (or horizontal asymmetric structure or a left-right asymmetric structure), with respect to the vibration apparatuses 333 and 335.
According to an embodiment of the present disclosure, the vibration apparatuses 333 and 335 can each include a long side and a short side. A distance (or separation distance or shortest distance) between the one or more holes 331o and the short side of the vibration apparatuses 333 and 335 can represent a ratio of a short-side length of the vibration apparatuses 333 and 335. According to an embodiment of the present disclosure, a distance between the one or more holes 331o and the vibration apparatuses 333 and 335 can be 60% or less of the short-side length of the vibration apparatuses 333 and 335.
The one or more holes 331o can be disposed closer to the vibration apparatuses 333 and 335 than a coupling member 320. The coupling member 320 can include a first coupling member 321 and a second coupling member 322. For example, the one or more holes 331o can be disposed closer to the vibration apparatuses 333 and 335 than the first coupling member 321 and the second coupling member 322. Accordingly, sound characteristics and/or sound pressure level characteristics of a low-pitched sound band can be enhanced.
According to an embodiment of the present disclosure, the one or more holes 331o may not overlap an opening part 310o. For example, the one or more holes 331o can be disposed to be spaced apart from the opening part 310o. Accordingly, a sound generated based on a vibration (or driving) of each of the vibration apparatuses 333 and 335 in the second space 313b can be output to the first space 313a through the one or more holes 331o, and sound characteristics and/or sound pressure level characteristics of a low-pitched sound band can be enhanced.
Each of the one or more holes 331o according to an embodiment of the present disclosure can be configured in a polygonal shape such as a circular shape, an oval shape, or a tetragonal shape, but embodiments of the present disclosure are not limited thereto.
According to an embodiment of the present disclosure, a sound generated based on a vibration (or driving) of each of the vibration apparatuses 333 and 335 at a rear surface of the vibration member 331 or the second space 313b of the enclosure 310 can be output to the first space 313a through the one or more holes 331o and can output (or radiated) through the opening part 310o of the first enclosure 311 and a hollow part 501 of a coupling part 500, and thus, sound characteristics and/or sound pressure level characteristics of a low-pitched sound band can be more enhanced.

The inventors have recognized that a sound characteristic is changed based on a structure of the coupling part 500. Therefore, the inventors have performed various research and experiments on the structure of the coupling part 500. Based on the extensive research and experiments, the inventors have invented a sound apparatus including the coupling part 500 for enhancing sound characteristics and/or sound pressure level characteristics and a vehicular apparatus including the sound apparatus. This will be described below.
With reference to
The coupling part 500 can further include a chamfer portion 503a.
The coupling part 500 can include a hollow part 501 which is connected to an internal space 313 of an enclosure 310 and includes the chamfer portion 503a. The chamfer portion 503a can be configured at the hollow part 501. For example, the hollow part 501 can be connected to the internal space 313 of the enclosure 310 through an opening part 310o of the enclosure 310.
The vehicle interior material 130 can include a first surface and a second surface different from (or opposite to) the first surface. The first surface can be a surface facing the enclosure 310. The vehicle interior material 130 can include a hole 137 configured at the first surface and the second surface. For example, the hole 137 of the vehicle interior material 130 can be configured to pass through the first surface and the second surface. For example, the latch member 503 can pass through the hole (or a through hole) 137 and can be coupled to the second surface (or an indoor surface or a rear surface) 130s of the vehicle interior material 130. For example, the latch member 503 can include the chamfer portion 503a. For example, the latch member 503 can overlap the second surface 130s of the vehicle interior material 130.
The chamfer portion 503a according to another embodiment of the present disclosure can include a non-rectangular shape (or a non-right-angled shape). For example, the chamfer portion 503a can include one or more of a curve shape (or a round shape) and a slope surface. For example, the chamfer portion 503a can have a curvature. Sound characteristics and/or sound pressure level characteristics can be changed based on a curvature of the chamfer portion 503a. For example, comparing with a case where the chamfer portion 503a has a rectangular shape, in a case where the chamfer portion 503a has a non-rectangular shape, it can be seen that peak and/or dip in a low-pitched sound band to a high-pitched sound band are/is improved, thereby enhancing a balance characteristic of a sound pressure level or a flatness characteristic of a sound pressure level. Furthermore, as a curvature of the chamfer portion 503a increases, a flatness characteristic of a sound pressure level and/or a sound pressure level characteristic in a high-pitched sound band can be more enhanced. Therefore, according to an embodiment of the present disclosure, because the coupling part 500 is configured to have a round shape or a slope surface, sound characteristics and/or sound pressure level characteristics in a low-pitched sound band including a sound of a low-pitched sound band can be enhanced, and peak and/or dip in a high-pitched sound band can be improved, thereby enhancing a balance characteristic of a sound pressure level or a flatness characteristic of a sound pressure level.

For example, the long axis of the hollow part 501 can be parallel to the short-side direction of the enclosure 310 or the second direction Y, but embodiments of the present disclosure are not limited thereto. For example, the short axis of the hollow part 501 can be parallel to a first direction X or a long-side direction of the enclosure 310, but embodiments of the present disclosure are not limited thereto. For example, the hollow part 501 can have a “*”-shape or a “+”-shape described above with reference to
According to another embodiment of the present disclosure, the coupling part 500 can be configured to have a width W. For example, the coupling part 500 can include a latch member 503 having the width W. For example, the latch member 503 can be configured to have the width W. For example, the width W of the latch member 503 can be a length which extends from an outer surface (an outer circumference surface) of the hollow part 501 in a direction (or a first direction X) parallel to the vehicle interior material 130. For example, the width W of the latch member 503 can be a length which extends from a lower outer surface of the hollow member 502 in the direction (or the first direction X) parallel to the vehicle interior material 130. The latch member 503 having the width W can overlap at least one of the vehicle interior material 130, a connection member 380, and an enclosure 310. For example, the width W of the latch member 503 can be a same as a short-side length of the hollow part 501. The width W of the latch member 503 or the short-side length of the hollow part 501 can be 1 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the width W of the latch member 503 or the short-side length of the hollow part 501 can be 1 mm to 5 mm, but embodiments of the present disclosure are not limited thereto.
According to an embodiment of the present disclosure, as a width W of the latch member 503 increases, a sound pressure level can be enhanced, and dust or particles flowing in from the outside can be reduced or minimized. According to an embodiment of the present disclosure, the width W of the latch member 503 can be 1 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the width W of the latch member 503 can be 1 mm to 5 mm, but embodiments of the present disclosure are not limited thereto.
According to an embodiment of the present disclosure, because a width W of the latch member 503 is configured to 1 mm or more, sound characteristics and/or sound pressure level characteristics can be enhanced in a pitched sound band including a sound of a low-pitched sound band, and peak and/or dip in a high-pitched sound band can be improved, thereby enhancing a balance characteristic of a sound pressure level and/or a flatness characteristic of a sound pressure level. According to an embodiment of the present disclosure, because the width W of the latch member 503 is configured to 1 mm or more, dust or particles flowing in from the outside can be reduced or minimized.
According to another embodiment of the present disclosure, the coupling part 500 can be configured to have a length L. The length L of the coupling part 500 can be a length which enables the sound apparatus 30 to be provided at the vehicle interior material 130. For example, the length L of the coupling part 500 can be smaller than a sum of thicknesses of the vehicle interior material 130, the connection member 380, and the enclosure 310. With respect a thickness direction Z of the vehicle interior material 130, the length L of the coupling part 500 can correspond to a length of the hollow part 501. The length L of the coupling part 500 can correspond to a length between the latch member 503 and the hook member 504. For example, the length L of the coupling part 500 can be a length between an upper surface of the latch member 503 contacting the interior material 130 and a lower surface of the hook member 504 contacting the enclosure 310. The length L of the coupling part 500 can be 10 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the length L of the coupling part 500 can be 10 mm or more and less than 19 mm, but embodiments of the present disclosure are not limited thereto.
According to another embodiment of the present disclosure, the sound apparatus 30 can be configured to include one or more of a shape of the coupling part 500, the width W of the coupling part 500, and the length L of the coupling part 500, thereby providing the sound apparatus 30 where sound characteristics and/or sound pressure level characteristics are more enhanced. For example, as a length L of the coupling part 500 decreases, a sound pressure level characteristic can be enhanced. According to an embodiment of the present disclosure, the length of the coupling part 500 can be 10 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the length L of the coupling part 500 can be 10 mm or more and less than 19 mm, but embodiments of the present disclosure are not limited thereto. For example, when the length L of the coupling part 500 is smaller than 10 mm, the dip and/or peak of a sound can be improved, but there can be a problem where it is difficult to equip a sound apparatus in a roof trim of a vehicular apparatus. According to an embodiment of the present disclosure, because the length L of the coupling part 500 is configured to 10 mm or more and less than 19 mm, sound characteristics and/or sound pressure level characteristics can be enhanced in a pitched sound band including a sound of a low-pitched sound band, and peak and/or dip in a high-pitched sound band can be improved, thereby enhancing a balance characteristic of a sound pressure level or a flatness characteristic of a sound pressure level.

In a case where the connection member 380 of
With reference to
The connection member 380 can include a first portion and a second portion. The second portion can be a periphery portion of an enclosure 310. The second portion can be a portion (or a region) between the vehicle interior material 130 and the periphery portion of the enclosure 310. The first portion can be the other portion, except the periphery portion, of the enclosure 310. For example, the first portion can correspond to a center portion of the enclosure 310 surrounded by the second portion corresponding to the periphery portion of the enclosure 310.
According to an embodiment of the present disclosure, the first portion of the connection member 380 can include an opening hole 380o connected to an internal space 313 of the enclosure 310. For example, the first portion of the connection member 380 can include an opening hole 380o connected to an internal space 313 of a first enclosure 311.
According to an embodiment of the present disclosure, the enclosure 310 or the first enclosure 311 can include at least one or more regions. For example, the enclosure 310 or the first enclosure 311 can include a first region A1, a second region A2, and a third region A3.
The first region A1 can correspond to a center portion of the enclosure 310 or the first enclosure 311. The first region A1 can be at the center portion of the enclosure 310 or the first enclosure 311. The second region A2 can correspond to a periphery portion, surrounding the center portion, of the enclosure 310 or the first enclosure 311. The third region A3 can be between the first region A1 and the second region A2. For example, the first portion of the connection member 380 can be at the first region A1 and the third region A3. For example, the second portion of the connection member 380 can be at the second region A2.
According to an embodiment of the present disclosure, the first portion and the second portion of the connection member 380 can have different thicknesses. For example, the connection member 380 can include the first portion and the second portion having different thicknesses. In the connection member 380, a thickness T1 of the first portion can differ from a thickness “T1+T2” of the second portion. For example, in the connection member 380, the thickness “T1+T2” of the second portion can be thicker than the thickness T1 of the first portion. For example, the thickness T1 of the connection member 380 at the first region A1 can differ from the thickness “T1+T2” of the connection member 380 at the second region A2. At least one of thicknesses of the connection members 30 at each of the first and third regions A1 and A3 can differ from the thickness “T1+T2” of the connection member 380 at the second region A2. For example, the thickness “T1+T2” of the connection member 380 at the second region A2 can be thicker than the thickness T1 of the connection member 380 at the first region A1.
According to an embodiment of the present disclosure, the second portion of the connection member 380 can have a thickness “T1+T2” which is thicker than the first portion, and thus, the periphery portion of the connection member 380 can be connected to or contact the vehicle interior material 130 without being partially detached (or lifted). Therefore, the periphery portion of the connection member 380 can be prevented from being partially detached (or lifted) from the vehicle interior material 130, and a vibration at a periphery portion of the enclosure 310 can be transferred to the vehicle interior material 130 without the loss of a vibration (or vibration transfer) at the periphery portion of the enclosure 310. A vibration at the periphery portion of the enclosure 310 can increase a vibration region of the vehicle interior material 130, and thus, can more improve or reinforce a sound characteristic of a low-pitched sound band. Therefore, a sound generated from a vibration of the sound apparatus 30 can be transferred to the vehicle interior material 130 without being lost, and thus, a sound of the low-pitched sound band can be more enhanced. For example, a sound generated from a vibration of the sound apparatus 30 can be transferred to the vehicle interior material 130 through the opening part 310o and the periphery portion of the enclosure 310, and thus, vibration efficiency transferred from the enclosure 310 to the vehicle interior material 130 can increase, thereby more enhancing sound characteristics and/or sound pressure level characteristics of the low-pitched sound band.
The connection member 380 according to an embodiment of the present disclosure can include a first connection member 381 and a second connection member 382.
The first connection member 381 can be at the first portion and the second portion. The first connection member 381 can be connected to the enclosure 310.

The second connection member 382 can be at the second portion. The second connection member 382 can be connected to a portion of the first connection member 381. The second connection member 382 can be on the first connection member 381 at the second portion. For example, the first portion can include only the first connection member 381 of the first connection member 381 and the second connection member 382. The first connection member 381 and the second connection member 382 can be together at the second portion. For example, the second portion can include all of the first connection member 381 and the second connection member 382. For example, the first connection member 381 and the second connection member 382 can be together at the second region A2.
The first portion and the second portion of the connection member 380 can have different widths (or sizes). In the connection member 380, a width of the first portion can be smaller than that of the second portion. For example, widths of the connection member 380 at the first regions A1 and the third regions A3 can be smaller than a width of the connection member 380 at the second regions A2. Accordingly, the connection member 380 can include the first portion and the second portion having different sizes (or widths) and different thicknesses.
The second connection member 382 can be at a periphery of the first connection member 381. The second connection member 382 can be configured to be stacked on the first connection member 381, at the second portion. The second connection member 382 can be configured to be stacked on the first connection member 381, at the second region A2. Accordingly, the thickness “T1+T2” of the second portion of the connection member 380 can be thicker than the thickness T1 of the first portion, and thus, the periphery portion of the enclosure 310 can be connected to (or contact) the vehicle interior material 130 without being partially detached (or lifted). For example, the second connection member 382 can be a cushion member or a pad member, but embodiments of the present disclosure are not limited thereto.

For example, the ethylene propylene rubber can be ethylene propylene diene monomer (EPDM), but embodiments of the present disclosure are not limited thereto. For example, a hardness of the EPDM can be 40 to 90, but embodiments of the present disclosure are not limited thereto. For example, a tensile strength of the EPDM can be 50 kg/cm2 to 200 kg/cm2, but embodiments of the present disclosure are not limited thereto. For example, a minimum elongation rate of the EPDM can be 200%, but embodiments of the present disclosure are not limited thereto. For example, a use temperature of the EPDM can be −30° C. to 110° C., but embodiments of the present disclosure are not limited thereto.
According to an embodiment of the present disclosure, a coupling member 320 can be configured in a material which differs from that of the connection member 380. For example, one of the first connection member 381 and the second connection member 382 can be configured in a material having elasticity (or a Young's modulus) which is higher than that of the coupling member 320.
According to an embodiment of the present disclosure, a width of the connection member 380 at the second portion can be greater than that of a width of the coupling member 320. For example, the width of the connection member 380 at the second region A2 can be greater than that of the width of the coupling member 320.
According to an embodiment of the present disclosure, each of the first connection member 381 and the second connection member 382 of the connection member 380 can have a compressive force (or contractive force) and an elastic restoring force and can be contracted or compressed by coupling between the coupling part 500 and the first enclosure 311. For example, the first connection member 381 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a first thickness T1 obtained through compression by a pressing force of the first enclosure 311. The second connection member 382 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a second thickness T2 obtained through compression by a pressing force of the first enclosure 311.
The first thickness T1 of the first connection member 381 can be equal to or different from the second thickness T2 of the second connection member 382. The first thickness T1 of the first connection member 381 and the second thickness T2 of the second connection member 382 can each be 0.5 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the first thickness T1 of the first connection member 381 and the second thickness T2 of the second connection member 382 can each be 0.5 mm to 3 mm, but embodiments of the present disclosure are not limited thereto.
The sound apparatus 30 according to another embodiment of the present disclosure can further include an air gap AG at a region between the enclosure 310 and the vehicle interior material 130. For example, the air gap AG can be at a region between the vehicle interior material 130 and the first portion of the connection member 380 or a region between the first portion and the second portion of the connection member 380. For example, the air gap AG can be at the third region A3 between the first region A1 and the second region A2 of the enclosure 310. For example, the air gap AG can be at a region between the third region A3 of the enclosure 310 and the vehicle interior material 130. For example, the air gap AG can be provided at the third region A3 between the first region A1 and the second region A2 of the enclosure 310, and thus, can minimize separation or interference between a vibration of the first region A1 and a vibration of the second region A2, thereby increasing a vibration force (or the amount of vibration) transferred from the second region A2 (for example, the periphery portion) of the enclosure 310 to the vehicle interior material 130. Accordingly, a band (a reproduction band) of a low-pitched sound band can expand, and thus, sound characteristics and/or sound pressure level characteristics of the low-pitched sound band can be more improved.
According to an embodiment of the present disclosure, the connection member 380 including the first and second portions having different thicknesses can be configured, thereby providing the sound apparatus 30 where sound characteristics and/or sound pressure level characteristics of the low-pitched sound band are/is more enhanced. According to an embodiment of the present disclosure, because the second connection member 382 is configured, a vibration area (or a vibration region) of a roof trim of a vehicular apparatus can be widened when coupling the sound apparatus 30 to the roof trim of the vehicular apparatus, and thus, sound characteristics and/or sound pressure level characteristics of the low-pitched sound band can be more enhanced.
With reference to
The enclosure 310 or the first enclosure 311 can be disposed on the vehicle interior material 130 so that the opening part 310o overlaps (or is connected to) the hole 137 of the vehicle interior material 130. The coupling part 500 can be connected or coupled to the sound apparatus 30 or the enclosure 310 through (an arrow direction) the hole 137 of the vehicle interior material 130 at an interior space of the vehicle. For example, the coupling part 500 can be connected or coupled to the sound apparatus 30 or the enclosure 310 through (an arrow direction) the second hole 137 of the vehicle interior material 130 and the hole 380o of the first connection member 381 at the interior space of the vehicle. For example, the coupling part 500 can be accommodated or inserted into the hole 137 of the vehicle interior material 130, the hole 380o of the first connection member 381, and the opening part 310o of the first enclosure 311 at the interior space of the vehicle. For example, the hook member 504 of the coupling part 500 can be connected or coupled to the opening part 310o of the first enclosure 311. For example, the hook member 504 of the coupling part 500 can be inserted (or accommodated) into the opening part 310o of the first enclosure 311 and can be connected or coupled to the groove portion 311g of the first enclosure 311, based on a hook coupling scheme.
Accordingly, the first enclosure 311 can be connected (or contact) the vehicle interior material 130 by the first connection member 381 and the second connection member 382 and coupling with the coupling part 500 and can vibrate the vehicle interior material 130 to output a sound based on a vibration of a vibration apparatus.
The first connection member 381 can have an initial thickness T1′ before compression (or contraction) and can be compressed (or contracted) to have a deformed thickness (or a compression thickness) T1, based on pressure applied from the enclosure 310 by coupling (or connection) between the coupling part 500 and the enclosure 310. For example, when the coupling part 500 is coupled (or connected) to the enclosure 310, a thickness of the first connection member 381 can be compressed from the initial thickness T1′ to the compression thickness T1, based on pressure applied from the enclosure 310, and thus, a vibration of the first region A1 in the first enclosure 311 can be efficiently transferred to the vehicle interior material 130 through the first portion of the first connection member 381. For example, when the sound apparatus 30 is separated (or detached) from the vehicle interior material 130 by the detachment of the coupling part 500, the first connection member 381 can be restored from the deformed thickness (or the compression thickness) T1 to the initial thickness T1′ by an elastic restoring force.
The second connection member 382 can have an initial thickness T2′ before compression (or contraction) and can be compressed (or contracted) to have a deformed thickness (or a compression thickness) T2, based on pressure applied from the enclosure 310 by coupling (or connection) between the coupling part 500 and the enclosure 310. For example, when the coupling part 500 is coupled (or connected) to the enclosure 310, a thickness of the second connection member 382 can be compressed from the initial thickness T1′ to the compression thickness T1, based on pressure applied from the enclosure 310, and thus, a vibration of the second region A2 at the first enclosure 311 can be efficiently transferred to the vehicle interior material 130 through the first connection member 381 which is compressed (or contracted) and the first portion of the second connection member 381. For example, when the sound apparatus 30 is separated (or detached) from the vehicle interior material 130 by the detachment of the coupling part 500, the second connection member 382 can be restored from the deformed thickness (or the compression thickness) T2 to the initial thickness T2′ by an elastic restoring force.
The vehicle interior material 130 connected to (or contacting) the enclosure 310 or the first enclosure 311 can be deformed to include a flexural portion or at least one curved portion, based on coupling (or connection) between the coupling part 500 and the enclosure 310, and thus, partial detachment occurring between the periphery portion of the enclosure 310 or the first enclosure 311 and the vehicle interior material 130 can be prevented by the second portion of the connection member 380 having a relatively thick thickness. Accordingly, a vibration at the periphery portion of the enclosure 310 or the first enclosure 311 can be transferred to the vehicle interior material 130 without the loss of a vibration (or vibration transfer) at the periphery portion of the first enclosure 311, and thus, vibration efficiency transferred from the enclosure 310 to the vehicle interior material 130 can increase, thereby further enhancing sound characteristics and/or sound pressure level characteristics of the low-pitched sound band.
The sound apparatus 30 described above with reference to
With reference to
The connection member 380 can include a first portion and a second portion. The first portion of the connection member 380 can include an opening hole 380o connected to an internal space 313 of the enclosure 310. For example, the first portion of the connection member 380 can include an opening hole 380o connected to the internal space 313 of the first enclosure 311. The enclosure 310 or the first enclosure 311 can include a first region A1, a second region A2, and a third region A3.
According to an embodiment of the present disclosure, the first portion and the second portion of the connection member 380 can have different thicknesses T3 and T4. For example, the connection member 380 can include the first portion and the second portion having different thicknesses T3 and T4. In the connection member 380, a thickness T3 of the first portion can differ from a thickness T4 of the second portion. For example, in the connection member 380, the thickness T4 of the second portion can be thicker than the thickness T3 of the first portion. For example, the thickness T3 of the connection member 380 at the first region A1 can differ from the thickness T4 of the connection member 380 at the second region A2. For example, the thickness T4 of the connection member 380 at the second region A2 can be thicker than the thickness T3 of the connection member 380 at the first region A1. For example, the connection member 380 may not be disposed at the third region A3 between the first region A1 and the second region A2 or at a portion between the first portion and the second portion.
According to an embodiment of the present disclosure, the second portion of the connection member 380 can have the thickness T4 which is thicker than the first portion, and thus, the periphery portion of the connection member 380 can be connected to or contact the vehicle interior material 130 without being partially detached (or lifted). Therefore, the periphery portion of the connection member 380 can be prevented from being partially detached (or lifted) from the vehicle interior material 130, and a vibration at a periphery portion of the enclosure 310 can be transferred to the vehicle interior material 130 without the loss of a vibration (or vibration transfer) at the periphery portion of the enclosure 310. A vibration at the periphery portion of the enclosure 310 can increase a vibration region of the vehicle interior material 130, and thus, can more improve or reinforce a sound characteristic of a low-pitched sound band. Therefore, a sound generated from a vibration of the sound apparatus 30 can be transferred to the vehicle interior material 130 without being lost, and thus, a sound of the low-pitched sound band can be more enhanced. For example, a sound generated from a vibration of the sound apparatus 30 can be transferred to the vehicle interior material 130 through the opening part 310o and the periphery portion of the enclosure 310, and thus, vibration efficiency transferred from the enclosure 310 to the vehicle interior material 130 can increase, thereby further enhancing sound characteristics and/or sound pressure level characteristics of the low-pitched sound band.
According to an embodiment of the present disclosure, the connection member 380 can include a first connection member 383 and a second connection member 384.
The first connection member 383 can be connected to the enclosure 310. The first connection member 383 can be at the first portion. The first connection member 383 can be only at the first portion of the first portion and the second portion. The first connection member 383 can be connected to (or attached on) the first enclosure 311 of the enclosure 310. For example, the first connection member 383 can be connected to (or attached on) a rear surface of the first enclosure 311. The first connection member 383 can be connected to (or attached on) the rear surface of the first enclosure 311 corresponding to the first portion of the first portion and the second portion. For example, the first connection member 383 can be connected to (or attached on) a center portion (or a rear center portion) of the first enclosure 311. For example, the first connection member 383 can be connected to (or attached to) only the first region A1 of the first to third regions A1, A2, and A3 of the enclosure 310.
According to an embodiment of the present disclosure, the first connection member 383 can include an opening hole 380o which is at the first portion and is connected to an internal space 313 of the enclosure 310. For example, the first connection member 383 can include an opening hole 380o which is at the first portion and is connected to the internal space 313 of the first enclosure 311.
The second connection member 384 can be at the second portion. The second connection member 384 can be only at the second portion of the first portion and the second portion and can be spaced apart from the first connection member 383. The second connection member 384 can be at the second portion of the first portion and the second portion to surround the first connection member 383 with an air gap AG therebetween. The second connection member 384 can be connected to (or attached on) the second area A2 of the enclosure 310. For example, the second connection member 384 can be connected to (or attached to) the rear surface of the first enclosure 311 corresponding to the second portion of the first portion and the second portion. For example, the second connection member 384 can be connected to (or attached on) a periphery portion (or a rear periphery portion) of the first enclosure 311. For example, the second connection member 384 can be connected to (or attached to) only the second region A2 of the first to third regions A1, A2, and A3 of the enclosure 310.
The first portion and the second portion of the connection member 380 can have different widths (or sizes). A width of the first portion can be smaller than that of a width of the second portion. For example, a width of the first connection member 383 at the first regions A1 can be smaller than a width of the second connection member 384 at the second regions A2. Accordingly, the first connection member 383 and the second connection member 384 can include different sizes (or widths) and different thicknesses.
Each of the first connection member 383 and the second connection member 384 can be a cushion member or a pad member, but embodiments of the present disclosure are not limited thereto.
The first connection member 383 can include a same material (or substance) as that of the second connection member 384. Each of the first connection member 383 and the second connection member 384 can be a high elastic rubber or the like, but embodiments of the present disclosure are not limited thereto. For example, each of the first connection member 383 and the second connection member 384 can include a rubber material, or can be configured in ethylene propylene diene rubber (or ethylene propylene diene M-class rubber), ethylene propylene rubber, or urethane rubber.
According to an embodiment of the present disclosure, a width of the connection member 380 at the second portion can be greater than that of a width of the coupling member 320. For example, a width of the connection member 380 at the second region A2 can be greater than that of the width of the coupling member 320.
According to an embodiment of the present disclosure, each of the first connection member 383 and the second connection member 384 of the connection member 380 can have a compressive force (or contractive force) and an elastic restoring force and can be contracted or compressed by coupling between the coupling part 500 and the first enclosure 311. For example, the first connection member 383 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a first thickness (or a third thickness) T3 obtained through compression by a pressing force of the first enclosure 311. The second connection member 384 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a second thickness (or a fourth thickness) T4 obtained through compression by a pressing force of the first enclosure 311.
The first thickness T3 of the first connection member 383 can be different from the second thickness T4 of the second connection member 382. The first thickness T3 of the first connection member 383 and the second thickness T4 of the second connection member 384 can each be 0.5 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the first thickness T3 of the first connection member 383 and the second thickness T4 of the second connection member 384 can each be 0.5 mm to 3 mm, but embodiments of the present disclosure are not limited thereto. For example, the first thickness T3 of the first connection member 383 and the second thickness T4 of the second connection member 384 can have different thicknesses within a range of 0.5 mm to 3 mm. For example, the second thickness T4 of the second connection member 384 can be thicker than the first thickness T3 of the first connection member 383 within a range of 0.5 mm to 3 mm.
The sound apparatus 30 according to another embodiment of the present disclosure can further include an air gap AG. For example, the air gap AG can be at a region between the vehicle interior material 130 and the first portion of the connection member 380 or a region between the first portion and the second portion of the connection member 380. For example, the air gap AG can be at the third region A3 between the first region A1 and the second region A2 of the enclosure 310. For example, the air gap AG can be at a region between the second region A2 of the enclosure 310 and the vehicle interior material 130. For example, the air gap AG can be provided at the third region A3 between the first region A1 and the second region A2 of the enclosure 310, and thus, can minimize separation or interference between a vibration of the first region A1 and a vibration of the second region A2, thereby increasing a vibration force (or the amount of vibration) transferred from the second region A2 (for example, the periphery portion) of the enclosure 310 to the vehicle interior material 130. Accordingly, a band (a reproduction band) of a low-pitched sound band can expand, and thus, sound characteristics and/or sound pressure level characteristics of the low-pitched sound band can be more improved.
According to an embodiment of the present disclosure, the connection member 380 including the first and second connection members 383 and 384 having different thicknesses T3 and T4 can be configured, thereby providing the sound apparatus 30 where sound characteristics and/or sound pressure level characteristics of the low-pitched sound band are/is more enhanced. According to an embodiment of the present disclosure, because the second connection member 384 is configured, a vibration area (or a vibration region) of a roof trim of a vehicular apparatus can be widened when coupling the sound apparatus 30 to the roof trim of the vehicular apparatus, and thus, sound characteristics and/or sound pressure level characteristics of the low-pitched sound band can be more enhanced.
With reference to
The enclosure 310 or the first enclosure 311 can be disposed on the vehicle interior material 130 so that the opening part 310o overlaps (or is connected to) the hole 137 of the vehicle interior material 130. The coupling part 500 can be connected or coupled to the sound apparatus 30 or the enclosure 310 through (an arrow direction) the hole 137 of the vehicle interior material 130 at an interior space (or an indoor space) of the vehicle. For example, the coupling part 500 can be connected or coupled to the sound apparatus 30 or the enclosure 310 through (an arrow direction) the second hole 137 of the vehicle interior material 130 and the hole 380o of the first connection member 383 at the interior space of the vehicle. For example, the coupling part 500 can be accommodated or inserted into the hole 137 of the vehicle interior material 130, the hole 380o of the first connection member 383, and the opening part 310o of the first enclosure 311 at the interior space of the vehicle. For example, the hook member 504 of the coupling part 500 can be connected or coupled to the opening part 310o of the first enclosure 311. For example, the hook member 504 of the coupling part 500 can be inserted (or accommodated) into the opening part 310o of the first enclosure 311 and can be connected or coupled to the groove portion 311g of the first enclosure 311, based on a hook coupling scheme.
Accordingly, the first enclosure 311 can be connected (or contact) the interior material 130 by the first connection member 383 and the second connection member 384 and coupling with the coupling part 500 and can vibrate the vehicle interior material 130 to output a sound based on a vibration of a vibration apparatus.
The first connection member 383 can have an initial thickness T3′ before compression (or contraction) and can be compressed (or contracted) to have a deformed thickness (or a compression thickness) T3, based on pressure applied from the enclosure 310 by coupling (or connection) between the coupling part 500 and the enclosure 310. For example, when the coupling part 500 is coupled (or connected) to the enclosure 310, a thickness of the first connection member 383 can be compressed from the initial thickness T3′ to the compression thickness T3, based on pressure applied from the enclosure 310, and thus, a vibration of the first region A1 in the first enclosure 311 can be efficiently transferred to the vehicle interior material 130 through the first connection member 381. For example, when the sound apparatus 30 is separated (or detached) from the vehicle interior material 130 by the detachment of the coupling part 500, the first connection member 383 can be restored from the deformed thickness (or the compression thickness) T3 to the initial thickness T3′ by an elastic restoring force.
The second connection member 384 can have an initial thickness T4′ before compression (or contraction) and can be compressed (or contracted) to have a deformed thickness (or a compression thickness) T4, based on pressure applied from the enclosure 310 by coupling (or connection) between the coupling part 500 and the enclosure 310. For example, when the coupling part 500 is coupled (or connected) to the enclosure 310, a thickness of the second connection member 384 can be compressed from the initial thickness T4′ to the compression thickness T4, based on pressure applied from the enclosure 310, and thus, a vibration of the second region A2 at the first enclosure 311 can be efficiently transferred to the interior material 130 through the second connection member 384 which is compressed (or contracted). For example, when the sound apparatus 30 is separated (or detached) from the vehicle interior material 130 by the detachment of the coupling part 500, the second connection member 384 can be restored from the deformed thickness (or the compression thickness) T4 to the initial thickness T4′ by an elastic restoring force.
The vehicle interior material 130 connected to (or contacting) the enclosure 310 or the first enclosure 311 can be deformed to include a flexural portion or at least one curved portion, based on coupling (or connection) between the coupling part 500 and the enclosure 310, and thus, partial detachment occurring between the periphery portion of the enclosure 310 or the first enclosure 311 and the vehicle interior material 130 can be prevented by the second connection member 384 having a relatively thick thickness. Accordingly, a vibration at the periphery portion of the enclosure 310 or the first enclosure 311 can be transferred to the vehicle interior material 130 without the loss of a vibration (or vibration transfer) at the periphery portion of the first enclosure 311, and thus, vibration efficiency transferred from the enclosure 310 to the vehicle interior material 130 can increase, thereby further enhancing sound characteristics and/or sound pressure level characteristics of the low-pitched sound band.

A portion between the one edge portion of the cover member 1313 and the vibration member 331 can accommodate or vertically (or up and down) cover the end portion 1320e of the signal supply member 1320. Accordingly, the signal supply member 1320 can be integrated (or configured) as one body with the vibration generating part 1311. Therefore, the sound generating module 330 or the first and second vibration apparatuses 333 and 335 can be implemented in a film type integrated with the signal supply member 1320. For example, the signal supply member 1320 can be configured as one part (or one component) with the vibration generating part 1311, thereby realizing an effect of uni-materialization. For example, the signal supply member 1320 can be configured as a signal cable, a flexible cable, a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multilayer printed circuit, or a flexible multilayer printed circuit board, but embodiments of the present disclosure are not limited thereto.
In each of the first and second vibration apparatuses 333 and 335, the signal supply member 1320 according to an embodiment of the present disclosure can include a plurality of signal lines 1321 and 1322. For example, the signal supply member 1320 can include a first signal line 1321 and a second signal line 1322.
The first signal line 1321 and the second signal line 1322 can protrude (or extend) from a body of the signal supply member 1320 to be parallel to a second direction Y. For example, each of the first signal line 1321 and the second signal line 1322 can be individually curved or bent.
The first signal line 1321 can be electrically connected to the first electrode part 1311b of the vibration generating part 1311. For example, the first signal line 1321 can be electrically connected or electrically and directly connected to at least a portion of the first electrode part 1311b of the vibration generating part 1311 at the one edge portion of the cover member 1313. For example, the first signal line 1321 can be directly connected to or in direct contact with the first electrode part 1311b between the first electrode part 1311b of the vibration generating part 1311 and the groove portion of the vibration member 331. Accordingly, the first signal line 1321 can supply a first driving signal supplied from a vibration driving part to the first electrode part 1311b of the vibration generating part 1311.
The second signal line 1322 can be electrically connected to the second electrode part 1311c of the vibration generating part 1311. For example, the second signal line 1322 can be electrically connected or electrically and directly connected to at least a portion of the second electrode part 1311c of the vibration generating part 1311 at the one edge portion of the cover member 1313. For example, the second signal line 1322 can be directly connected to or in direct contact with the second electrode part 1311c between the cover member 1313 and the second electrode part 1311c of the vibration generating part 1311. Accordingly, the second signal line 1322 can supply a second driving signal supplied from the vibration driving part to the second electrode part 1311c of the vibration generating part 1311.
According to an embodiment of the present disclosure, in each of the first and second vibration apparatuses 333 and 335, the first signal line 1321 and the second signal line 1322 of the signal supply member 1320 can be integrated as one body with the vibration generating part 1311, and thus, a soldering process for an electrical connection between the vibration generating part 1311 and the signal supply member 1320 may not be needed, a manufacturing process and a structure of the vibration apparatus 333 and 335 can be simplified, and a hazardous process can be reduced.

In each of the first and second vibration apparatuses 333 and 335, the first signal supply member 1320 can be configured to supply the driving signal supplied from a driving circuit part to the vibration generating part 1311 of the first vibration generators 333A and 335A. The first signal supply member 1320 can be configured to be electrically connected to the first electrode part 1311b and the second electrode part 1311c of the vibration part 1311a. A portion of the first signal supply member 1320 can be accommodated (or inserted) between the cover member 1313 and the vibration member 331. The first signal supply member 1320 electrically connected to the first vibration generators 333A and 335A of each of the first and second vibration apparatuses 333 and 335 can be substantially a same as the signal supply member 1320 described above with reference to
