This application claims priority to Korean Patent Application No. 10-2023-0039723 filed in the Republic of Korea on Mar. 27, 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 can include a sound apparatus which outputs a sound based on an audio signal output from a multimedia device, and 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 and a vehicular apparatus including the same, which can enhance a sound characteristic and/or a sound pressure level characteristic.

In a sound apparatus and a vehicular apparatus including the same according to one or more embodiments of the present disclosure, a sound characteristic and/or a sound pressure level characteristic in a pitched sound band including a sound of a low-pitched sound band can be enhanced.
In a sound apparatus and a vehicular apparatus including the same according to one or more embodiments of the present disclosure, a signal supply member and a vibration generating apparatus can be configured as one part (or one component), thereby realizing an effect of uni-materialization.
In a sound apparatus and a vehicular apparatus including the same according to one or more embodiments of the present disclosure, a protrusion part and a coupling part can be configured as one part (or one component), thereby realizing an effect of uni-materialization.
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, 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 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. “Embodiments,” “examples,” “aspects,” and the like should not be construed as preferred or advantageous over other implementations. An embodiment, an example, an example aspect, an aspect, or the like can refer to one or more aspects, one or more examples, one or more example embodiments, one or more aspects, or the like, unless stated otherwise. Further, the term “may” encompasses all the meanings of the term “can.”
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 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, 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 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 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 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 two or more of the first item, the second item, and the third item or (ii) only one of the first item, the second item, or 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); or 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, 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.
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 base member 131 can be an injection material which is implemented by an injection process using a thermoplastic resin or a thermosetting resin, but embodiments of the present disclosure are not limited thereto. The base member 131 can be configured to cover an inner portion of a vehicle 10. For example, the base member 131 can be configured to cover one surface (or an inner surface) of at least one or more of a main frame, a side frame, a door frame, and a handle frame, which are exposed at the indoor space IS of the vehicle 10.
The base member 131 can include one or more of a flat portion and a curved portion. For example, the base member 131 can have a surface structure corresponding to a surface structure of a corresponding vehicle structure, or can have a surface structure which differs from a surface structure of a corresponding vehicle structure.
The surface member 133 can be disposed on the base member 131. The surface member 133 can cover the base member 131 at the inner portion or the indoor space IS of the vehicle 10 and can be exposed at the inner portion or the indoor space IS of the vehicle 10.

The sound apparatus 30 can be covered by the vehicle interior material 130. The sound apparatus 30 can be configured to vibrate the vehicle interior material 130 including the base member 131 and the surface member 133 to output a sound S toward the inner portion or the indoor space IS of the vehicle 10.
The sound apparatus 30 according to another embodiment of the present disclosure can output the sound S toward the indoor space IS of the vehicle 10 by using the vehicle interior material as a vibration plate or a sound vibration plate and can output a realistic sound S or stereo sound including a multichannel toward the indoor space IS of the vehicle 10.
According to another embodiment of the present disclosure, the sound apparatus 30 can be surrounded by an enclosure. A space can be provided between the sound apparatus 30 and the enclosure, and a sound (or a sound pressure level) can be output based on a vibration of the vehicle interior material 130 based on air between the sound apparatus 30 and the enclosure. However, there can be a problem where a sound of the low—pitched sound band is not output, and there can be a problem where the flatness of a sound pressure level is reduced because the number of peaks and dips occurring in a reproduction frequency band of a sound (or a sound pressure level) generated based on a vibration of the vehicle interior material 130 increases and each of a highest sound pressure level and a lowest sound pressure level occurring in a reproduction frequency band of a sound (or a sound pressure level) generated based on a vibration of the vehicle interior material 130 increases. The peak can be a phenomenon where a sound pressure level bounces in a specific frequency, and the dip can be a phenomenon where a low sound pressure level is generated as the occurrence of a sound having a specific frequency is reduced. The flatness of a sound characteristic can be a level of a deviation between a highest sound pressure and a lowest sound pressure.
The inventors of the present disclosure have performed extensive research and experiments for implementing a sound apparatus and a vehicular apparatus including the same, in which a sound characteristic of the low-pitched sound band can be improved and the flatness of a sound pressure level can be enhanced. Based on the extensive research and experiments, the inventors of the present disclosure have invented a sound apparatus and a vehicular apparatus including the same, which can output a sound including a high-pitched sound band and the low-pitched sound band and can enhance the flatness of a sound pressure level. This will be described below in detail.

Therefore, a band of the low-pitched sound band can extend, and thus, a sound characteristic of the low-pitched sound band can be improved. Because a pressure (or air pressure) of the first space 313a is reduced by the opening portion 3100, 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 extend, thereby enhancing a sound characteristic and/or a sound pressure level characteristic 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.

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 based on 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 vibration generator 1310 can vibrate (or displace or drive) in a vertical direction (or a thickness direction) Z as contraction and/or expansion are alternately repeated by an inverse piezoelectric effect.
The vibration generator 1310 can be configured as a ceramic-based piezoelectric material capable of implementing a relatively strong vibration, or can be configured as a piezoelectric ceramic having a perovskite-based crystal structure. For example, the vibration generator 1310 can be a vibration generating device, a vibration film, a vibration generating film, a vibrator, an active vibrator, an active vibration generator, an actuator, an exciter, a film actuator, a film exciter, an ultrasonic actuator, or an active vibration member, or the like, but embodiments of the present disclosure are not limited thereto.

For example, the vibration portion 1311a can be a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a piezoelectric composite layer, a piezoelectric composite, or a piezoelectric ceramic composite, or the like, but embodiments of the present disclosure are not limited thereto.
The vibration portion 1311a can be configured as a ceramic-based material capable of implementing a relatively strong vibration, or can be configured as a piezoelectric ceramic having a perovskite-based crystalline structure.

The second electrode portion 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 portion 1311a. The second electrode portion 1311c can have a same size as the vibration portion 1311a, or can have a size which is smaller than the vibration portion 1311a. For example, the second electrode portion 1311c can have a same shape as the vibration portion 1311a, but embodiments of the present disclosure are not limited thereto.
According to an embodiment of the present disclosure, in order to prevent electrical short circuit between the first electrode portion 1311b and the second electrode portion 1311c, each of the first electrode portion 1311b and the second electrode portion 1311c can be formed at a remaining portion except a periphery portion of the vibration portion 1311a. For example, the first electrode portion 1311b can be formed at an entire remaining portion except a periphery portion of the first surface 1311s1 of the vibration portion 1311a. For example, the second electrode portion 1311c can be formed at an entire remaining portion except a periphery portion of the second surface 1311s2 of the vibration portion 1311a. For example, a distance between a lateral surface (or a sidewall) of each of the first electrode portion 1311b and the second electrode portion 1311c and a lateral surface (or a sidewall) of the vibration portion 1311a can be at least 0.5 mm or more. For example, the distance between the lateral surface of each of the first electrode portion 1311b and the second electrode portion 1311c and the lateral surface of the vibration portion 1311a can be at least 1 mm or more, but embodiments of the present disclosure are not limited thereto.

For example, a polarization direction (or a poling direction) formed in the vibration portion 1311a can be formed or aligned (or arranged) from the first electrode portion 1311b to the second electrode portion 1311c, but embodiments of the present disclosure are not limited thereto. For example, the polarization direction (or the poling direction) formed in the vibration portion 1311a can be formed or aligned (or arranged) from the second electrode portion 1311c to the first electrode portion 1311b.
The vibration portion 1311a can alternately and repeatedly contract and/or expand by an inverse piezoelectric effect based on a driving signal applied to the first electrode portion 1311b and the second electrode portion 1311c from the outside to vibrate. For example, the vibration portion 1311a can vibrate in a vertical direction (or thickness direction) and in a planar direction by the signal applied to the first electrode portion 1311b and the second electrode portion 1311c. The vibration portion 1311a can be displaced (or vibrated or driven) by contraction and/or expansion of the planar direction, thereby improving a sound characteristic and/or a sound pressure level characteristic of the vibration generator 1310.

For example, the first cover member 1313 can be at the first electrode portion 1311b. For example, the first cover member 1313 can be configured to have a larger size than the vibration generating part 1311. The first cover member 1313 can be configured to protect the first surface of the vibration generating part 1311 and the first electrode portion 1311b.

For example, the first signal line 1323a and the second signal line 1323b can be implemented in a line shape by patterning of a metal layer (or a conductive layer) formed or deposited at the first surface of the base member 1321.
End portions (or distal end portions or one sides) of the first signal line 1323a and the second signal line 1323b can be separated from each other, and thus, can be individually curved or bent.
The end portion (or the distal end portion or the one side) of the first signal line 1323a can be electrically connected to the first electrode portion 1311b of the vibration generating part 1311. For example, the end portion of the first signal line 1323a can be electrically connected to at least a portion of the first electrode portion 1311b of the vibration generating part 1311 in the one edge portion of the first cover member 1313.

For example, the end portion of the second signal line 1323b can be electrically connected to or directly contact the second electrode portion 1311c of the vibration generating part 1311. For example, the end portion of the second signal line 1323b can be electrically connected to the second electrode portion 1311c by a conductive double-sided tape. Accordingly, the second signal line 1323b can be configured to transfer a second driving signal, supplied from the driving circuit part (or the vibration driver), to the second electrode portion 1311c of the vibration generating part 1311.
The signal supply member 1320 according to an embodiment of the present disclosure can further include an insulation layer 1325.

Accordingly, the end portion (or one side) of the first signal line 1323a can be maintained with being electrically connected to the first electrode portion 1311b of the vibration generating part 1311, and the end portion (or one side) of the second signal line 1323b can be maintained with being electrically connected to the second electrode portion 1311c of the vibration generating part 1311. In addition, the end portion (or one side) of the signal supply member 1320 can be inserted (or accommodated) and fixed between the vibration generating part 1311 and the first cover member 1313, and thus, a contact defect between the vibration generator 1310 and the signal supply member 1320 caused by the movement of the signal supply member 1320 can be prevented.
In the signal supply member 1320 according to an embodiment of the present disclosure, each of the end portion (or one side) of the base member 1321 and the end portion (or one side) 1325a of the insulation layer 1325 can be removed. For example, each of the end portion of the first signal line 1323a and the end portion of the second signal line 1323b can be exposed at the outside without being supported or covered by each of the end portion (or one side) of the base member 1321 and the end portion (or one side) 1325a of the insulation layer 1325, respectively. For example, the end portion (or one side) of each of the first signal line 1323a and the second signal line 1323b can protrude (or extend) to have a certain length from an end 1321e of the base member 1321 or an end 1325e of the insulation layer 1325. Accordingly, each of the end portion (or the distal end portion or the one side) of each of the first signal line 1323a and the second signal line 1323b can be individually or independently bent.
The end portion (or one side) of the first signal line 1323a, which is not supported by the end portion (or one side) of the base member 1321 and the end portion 1325a of the insulation layer 1325, can be directly connected to or directly contact the first electrode portion 1311b of the vibration generating part 1311.

According to an embodiment of the present disclosure, a portion of the signal supply member 1320 or a portion of the base member 1321 can be disposed or inserted (or accommodated) between the first cover member 1313 and the second cover member 1315, and thus, the signal supply member 1320 can be integrated (or configured) as one body with the vibration generating part 1311. Accordingly, the vibration generating part 1311 and the signal supply member 1320 can be configured as one part (or one component), and thus, an effect of uni-materialization can be obtained.
According to an embodiment of the present disclosure, the first signal line 1323a and the second signal line 1323b of the signal supply member 1320 can be integrated (or configured) as one body with the vibration generator 1310, and thus, a soldering process for an electrical connection between the vibration generator 1310 and the signal supply member 1320 may not be needed. Accordingly, a manufacturing process and a structure of the vibration apparatus 333 and 335 can be simplified, and hazards associated with the soldering process can be reduced.
