This application claims priority to Korean Patent Application No. 10-2023-0078529 filed in the Republic of Korea on Jun. 19, 2023, the entire contents of which is hereby expressly incorporated by reference into the present application.
The present disclosure relates to a sound apparatus for a vehicle 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 sound apparatus can include 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 device.
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 cannot 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 a sound characteristic and/or a sound pressure level characteristic of a sound apparatus for vehicles. Based on the extensive research and experiments, the inventors have invented a sound apparatus for a vehicle and a vehicular apparatus including the same, which can enhance a sound characteristic and/or a sound pressure level characteristic.

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 exemplary 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, and 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 methods, 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. Unless stated otherwise, the same reference numerals may be used to refer to the same or substantially the same elements throughout the specification and the 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, dimensions (e.g., sizes, lengths, widths, heights, thicknesses, locations, radii, diameters, and areas), dimensions, ratios, angles, numbers, the number of elements, 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. 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,” “composed of,” or the like is used with respect to one or more elements (e.g., layers, films, regions, components, sections, members, parts, regions, areas, portions, steps, operations, and/or the like), 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. Embodiments are example embodiments. Aspects are example aspects. Further, in one or more implementations, “embodiments,” “aspects,” “examples,” and the like should not be construed to be 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 and coverages of the term “may.”
In one or more aspects, unless explicitly stated otherwise, an 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 exemplary 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, members, parts, regions, areas, portions, steps, operations, and/or the like), these elements should not be limited by these terms, for example, to any particular order, precedence, or number of elements. These terms are used only to distinguish one element from another. For example, a first element can denote a second element, and, similarly, a second element can denote 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, sequence, 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,” “disposed,” or the like in, on, with or to another element can be understood, for example, as that at least a portion of the element is provided, disposed, connected, coupled or the like in, on, with or to at least a portion of another element, or that the entirety of the element is provided, disposed in, connected, coupled or the like in, on, with or to another element. The phrase that an element (e.g., layer, film, region, component, section, or the like) “contacts,” “overlaps,” or the like with another element can be understood, for example, 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 that is, 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.
In addition, “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.

According to an embodiment of the present disclosure, the first fixing part 317a can be a first periphery portion of the first enclosure 311. The second fixing part 317b can be a second periphery portion, which is opposite to the first periphery portion, of the first enclosure 311.

The second fixing part 317b can be a second periphery portion, adjacent to the second short side, of the first enclosure 311. Accordingly, the first and second periphery portions of the first enclosure 311 can pass through a short side of a vibration member 331 or a short side of the second enclosure 312 and can extend (or protrude) along the first direction X. The first enclosure 311 can have a size which is greater than that of each of the second enclosure 312 or the vibration member 331.

The coupling boss 515 at the hook member 513 of the first supporting member 510 can contact an upper surface of the first fixing part 317a, and thus, the first fixing part 317a can be disposed (or interposed) or fixed between the vehicle interior material 130 and the coupling boss 515.
According to an embodiment of the present disclosure, a distance L1 between the coupling boss 515 of the first supporting member 510 and the first surface 130s1 of the vehicle interior material 130 can be smaller than a distance between an upper surface of the first enclosure 311 (or the upper surface of the first fixing part 317a) and the first surface 130s1 of the vehicle interior material 130. For example, the distance L1 between the coupling boss 515 of the first supporting member 510 and the first surface 130s1 of the vehicle interior material 130 can be smaller than a sum of a thickness of the first enclosure 311 and a thickness of the connection member 350. The coupling boss 515 of the first supporting member 510 can be coupled to the upper surface of the first fixing part 317a at the first enclosure 311, based on the hook coupling scheme. Accordingly, the first fixing part 317a at the first enclosure 311 can be fixed with being pressed between the coupling boss 515 of the first supporting member 510 and the first surface 130s1 of the vehicle interior material 130 by pressing (or elasticity) of the connection member 350.

The second fixing part 317b can be coupled to the second supporting member 520 of the supporting part 500 coupled (or attached) to the vehicle interior material 130 adjacent to the second side, which is opposite to the first side, of the first enclosure 311, based on the hook coupling scheme.

The coupling boss 515 at the hook member 513 of the second supporting member 520 can contact an upper surface of the second fixing part 317b, and thus, the second fixing part 317b can be disposed (or interposed) or fixed between the vehicle interior material 130 and the coupling boss 515.
According to an embodiment of the present disclosure, a distance L1 between the coupling boss 515 of the second supporting member 520 and the first surface 130s1 of the vehicle interior material 130 can be smaller than a distance between the upper surface of the first enclosure 311 (or the upper surface of the second fixing part 317b) and the first surface 130s1 of the vehicle interior material 130.

The coupling boss 515 of the second supporting member 520 can be coupled to the upper surface of the second fixing part 317b at the first enclosure 311, based on the hook coupling scheme. Accordingly, the second fixing part 317b at the first enclosure 311 can be fixed with being pressed between the coupling boss 515 of the second supporting member 520 and the first surface 130s1 of the vehicle interior material 130 by pressing (or elasticity) of the connection member 350. Therefore, the second supporting member 520 can support (or fix) the second periphery portion of the first enclosure 311 while surrounding the second short side of the first enclosure 311.
The first supporting member 510 and the second supporting member 520 can be coupled (or attached) to the first surface 130s1 of the vehicle interior material 130 to have an interval corresponding to a long-side length of the sound apparatus 30 and can be hook-coupled to each of the first fixing part 317a and the second fixing part 317b at the first enclosure 311, based on the hook coupling scheme, and thus, can support (or fix) the sound apparatus 30 and can connect (or coupe or contact) the sound apparatus 30 to the first surface 130s1 of the vehicle interior material 130. For example, the first enclosure 311 at the sound apparatus 30 can be interposed (or disposed) between the first supporting member 510 and the second supporting member 520 and can be hook-coupled to the coupling boss 515 at the hook member 513 of each of the first supporting member 510 and the second supporting member 520, and thus, can be pressed between the first surface 130s1 of the vehicle interior material 130 and the coupling boss 515 at the hook member 513 and can be connected (or coupled or contact) to the first surface 130s1 of the vehicle interior material 130. Accordingly, based on the hook coupling scheme using the hook member 513, a coupling process between the sound apparatus 300 and a vehicle structure can be easily performed. Based on the hook coupling scheme, a process of attaching or mounting the sound apparatus 30 on the vehicle interior material 130 and/or a process of separating or detaching the sound apparatus 30 on the vehicle interior material 130 can be easily performed.
According to an embodiment of the present disclosure, in a state where the enclosure 310 is hook-coupled to the supporting part 500 by the hook coupling scheme and is connected (or coupled) to the first surface 130s1 of the vehicle interior material 130, the sound generating module 330 can generate a sound pressure level (or sound or sound wave) at an internal space 313 of the enclosure 310 to vibrate the first enclosure 311 and can vibrate the vehicle interior material 130 based on a vibration of the first enclosure 311 to output (or generate) a sound.
