[0063] Throughout the drawings and detailed description, unless otherwise described, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustration, and / or convenience, the sizes, lengths, and thicknesses of layers, regions, and elements and their descriptions may be exaggerated. DETAILED DESCRIPTION

[0064] Reference is now made in detail to various aspects of the present disclosure, examples of which may be illustrated in the accompanying drawings. In the following description, when a detailed description of a known method, function, structure, or configuration may unnecessarily obscure various aspects of the present disclosure, a detailed description of such known function or configuration may be omitted for the sake of brevity. In addition, repeated descriptions may be omitted for the sake of brevity. The described progression of processing steps and / or operations is a non-limiting example.

[0065] The order of steps and / or operations is not limited to the order set forth herein, and may be changed to occur in an order different from that described herein, except for steps and / or operations that must occur in a particular order. In one or more examples, two operations in succession may be performed substantially simultaneously, or the two operations may be performed in a reverse order or in a different order depending on the functions or operations involved.

[0066] Unless otherwise stated, even if the same reference numerals are shown in different figures, they may refer to the same elements throughout. Unless otherwise stated, the same reference numerals may be used to refer to the same or substantially the same elements throughout the specification and drawings. In one or more aspects, unless otherwise stated, the same elements (or elements with the same names) in different figures may have the same or substantially the same functions and properties. The names of the various elements used in the following description are selected for convenience only and may therefore differ from the names used in the actual product.

[0067] By referring to the various aspects described in the accompanying drawings, the advantages and features of the present disclosure and the implementation methods thereof are explained. However, the present disclosure can be embodied in different forms and should not be construed as being limited to the example aspects set forth herein. On the contrary, these example aspects are examples and are provided so that the present disclosure can be thorough and complete, to help those skilled in the art understand the inventive concept, without limiting the scope of protection of the present disclosure.

[0068] The shapes, dimensions (e.g., size, length, width, height, thickness, position, radius, diameter, and area), proportions, ratios, angles, numbers, number of elements, etc. disclosed herein, including those shown in the drawings, are merely examples, and therefore, the disclosure is not limited to the details shown. However, it is noted that the relative sizes of the components shown in the drawings are part of the disclosure.

[0069] When terms such as "including", "having", "comprising", "containing", "consisting of", "made of", "formed of", "composed of", etc. are used with respect to one or more elements (e.g., layers, films, regions, parts, sections, number, parts, regions, areas, parts, steps, operations, etc.), one or more other elements may be added unless terms such as "only" are used. The terms used in the present disclosure are only used to describe example aspects and are not intended to limit the scope of the present disclosure. Unless the context clearly indicates otherwise, terms in the singular may include plural forms.

[0070] Unless otherwise stated, the word "exemplary" is used to mean serving as an example or illustration. An embodiment is an exemplary embodiment. An aspect is an example aspect. In one or more implementations, "embodiment," "aspect," "example," etc. should not be construed as being superior or preferred over other implementations. Unless otherwise stated, an aspect, an example, an example aspect, etc. may refer to one or more aspects, one or more examples, one or more example aspects, etc. In addition, the term "may" encompasses all meanings of the term "can."

[0071] In one or more aspects, unless otherwise expressly stated, an element, feature, or corresponding information (e.g., level, range, dimension, size, etc.) is interpreted as including an error or tolerance range, even if no explicit description of such error or tolerance range is provided. The error or tolerance range may be caused by various factors (e.g., process factors, internal or external influences, noise, etc.). When interpreting a numerical value, unless otherwise expressly stated, the value is interpreted as including an error range.

[0072] When describing a positional relationship, when describing the positional relationship between two components (e.g., layers, films, regions, components, sections, etc.) using, for example, “on…”, “over…”, “on top of…”, “over…”, “under…”, “above”, “below…”, “near”, “nearby”, “near…”, “at the side or on…”, etc., one or more other components may be located between the two components unless more restrictive terms such as “immediately adjacent to”, “directly” or “close to” are used. For example, when a structure is described as being relative to another structure as follows: When referring to the positions: "on", "above", "on the top of", "above", "below", "above", "below", "below", "near", "close", "adjacent", "beside", "near", "to the side or on", etc., the description should be interpreted to include the situation where the structures are in contact with each other and the situation where one or more additional structures are disposed or inserted therebetween. In addition, the terms "front", "back", "back", "left", "right", "top", "bottom", "downward", "upward", "upper", "lower", "up", "down", "column", "row", "vertical", "horizontal", etc. refer to any reference system.

[0073] Spatially relative terms such as "below," "below," "lower," "above," "upper," etc. may be used to describe the correlation between various elements (e.g., layers, films, regions, components, sections, etc.) as shown. Spatially relative terms should be understood as terms that include different orientations of elements in use or operation in addition to the orientations depicted in the drawings. For example, if the elements shown in the drawings are flipped, elements described as being "below" or "below" other elements will be oriented "above" the other elements. Thus, the term "below," which is an example term, may include all directions of "above" and "below." Similarly, the exemplary terms "above" or "on" may include both directions of "above" and "below."

[0074] When describing a temporal relationship, when the temporal order is described as, for example, "after", "subsequently", "next", "before", "previously", "in front of", etc., discontinuity or non-sequential situations may be included, and thus one or more other events may occur in between, unless more restrictive terms such as "just after", "immediately" or "directly" are used.

[0075] Terms such as "below," "lower," "above," "upper," etc. may be used herein to describe the relationship between elements shown in the drawings. It should be understood that these terms are spatially relative and based on the orientation depicted in the drawings.

[0076] It should be understood that although the terms "first", "second", etc. can be used to describe various elements (e.g., layers, films, regions, parts, sections, numbers, parts, regions, regions, parts, steps, operations, etc.) in this article, these elements should not be limited by these terms, for example, not limited by any particular order, priority or number of elements. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present disclosure, the first element may refer to the second element, and similarly, the second element may refer to the first element. In addition, without departing from the scope of the present disclosure, the first element, the second element, etc. can be arbitrarily named according to the convenience of those skilled in the art. For the sake of clarity, the function or structure of these elements (e.g., the first element, the second element, etc.) is not limited by the ordinal number or name in front of the element. In addition, the first element may include one or more first elements. Similarly, the second element, etc. may include one or more second elements, etc.

[0077] When describing elements of the present disclosure, terms such as "first", "second", "A", "B", "(a)", "(b)", etc. may be used. These terms are intended to identify corresponding elements from other elements, and these terms are not used to limit the nature, basis, sequence, order or number of the elements.

[0078] When an element (for example, a layer, a film, a region, a component, a section, etc.) is described as being “connected,” “coupled,” “attached,” “adhered,” etc. to another element, unless otherwise specified, the element may not only be directly connected, coupled, attached, adhered, etc. to the other element but may also be indirectly connected, coupled, attached, adhered, etc. to the other element by disposing or inserting one or more intervening elements between the elements.

[0079] When an element (for example, a layer, film, region, component, section, etc.) is “contacted”, “overlapped”, etc. with another element, unless otherwise specified, the element may not only be directly in contact with, overlapped with, etc., but may also be indirectly in contact with, overlapped with, etc., with the other element by having one or more intervening elements disposed or inserted between the elements.

[0080] The phrase that an element (e.g., a layer, a film, a region, a component, a section, etc.) is "provided," "arranged," "connected," "coupled," etc. in, on, with, or to another element may be understood, for example, as at least a portion of the element being provided, arranged, connected, coupled, etc. in, on, with, or to at least a portion of another element, or as the entire element being provided, arranged, connected, coupled, etc. in, on, with, or to another element. The phrase that an element (e.g., a layer, a film, a region, a component, a section, etc.) "contacts," "overlaps," etc. with another element may be understood, for example, as at least a portion of the element contacts, overlaps, etc. with at least a portion of another element, the entirety of the element contacts, overlaps, etc. with at least a portion of another element, or at least a portion of the element contacts, overlaps, etc. with the entirety of another element.

[0081] Terms such as "row" or "direction" should not be interpreted solely based on the geometric relationship of the corresponding rows or directions being parallel or perpendicular to each other. Such terms may refer to a wider range of lines or directions: within the wider range of lines or directions, the components of the present disclosure can operate functionally. For example, terms "first direction", "second direction", etc., such as directions parallel or perpendicular to the "x-axis", "y-axis", or "z-axis", should not be interpreted solely based on the geometric relationship of the corresponding directions being parallel or perpendicular to each other, and may refer to directions with wider directivity within the range within which the components of the present disclosure can operate functionally.

[0082] The term "at least one" should be understood to include any and all combinations of one or more of the associated listed items. For example, each of the phrases "at least one of the first, second, or third item" and "at least one of the first, second, and third items" can mean: (i) a combination of items provided by one or more of the first, second, and third items; or (ii) only one of the first, second, and third items.

[0083] The expression of a first element, a second element “and / or” a third element should be understood to cover one of the first element, the second element, and the third element, and any and all combinations of the first element, the second element, and the third element. As an example, A, B, and / or C covers only A; only B; only C; any one of A, B, and C (e.g., A, B, or C); or some combination of A, B, and C (e.g., A and B; A and C; or B and C); and all of A, B, and C. In addition, the expression “A / B” may be understood as A and / or B. For example, the expression “A / B” may refer to only A; only B; A or B; or A and B.

[0084] In one or more aspects, unless otherwise stated, for convenience, the terms "between" and "wherein" can be simply used interchangeably. For example, the expression "between multiple elements" can be understood as in multiple elements. In another example, the expression "in multiple elements" can be understood as between multiple 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. In addition, when an element (e.g., a layer, a film, a region, a component, a section, etc.) 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 may also be present.

[0085] In one or more aspects, unless otherwise specified, for convenience, the phrases "each other" and "mutually" may be simply used interchangeably. For example, the expression "different from each other" may be understood as different from each other. In another example, the expression "different from each other" may be understood as different from each other. In one or more examples, the number of elements involved in the foregoing statements may be two. In one or more examples, the number of elements involved in the foregoing statements may be more than two.

[0086] In one or more aspects, the phrases "one or more of" and "one or more of" may be used simply interchangeably for convenience unless otherwise indicated.

[0087] The term "or" means an inclusive or rather than an exclusive or. For example, unless otherwise specified or clear from the context, the statement "x uses a or b" means any of the natural inclusive permutations. For example, "a or b" may mean "a", "b", or "a and b". For example, "a, b or c" may mean "a", "b", "c", "a and b", "b and c", "a and c", or "a, b, and c".

[0088] The features of the various aspects of the present disclosure may be coupled or combined in part or in their entirety, may be technically associated with each other, and may be operated, linked or driven together in various ways. The various aspects of the present disclosure may be implemented or performed independently of one another, or may be implemented or performed together with a common reliance or related relationship. In one or more aspects, the parts of each device according to the various aspects of the present disclosure may be operationally coupled and configured.

[0089] Unless otherwise defined, the terms (including technical and scientific terms) used herein have the same meaning as commonly understood by a person of ordinary skill in the art to which the exemplary aspects belong. It should also be understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having, for example, a meaning consistent with their meaning in the relevant technical context, and should not be interpreted as an idealized or overly formal meaning, unless otherwise explicitly defined herein.

[0090] The terms used herein have been selected as common terms in the relevant technical field; however, other terms may exist according to the development and / or change of technology, convention, preference of technicians, etc. Therefore, the terms used herein should not be understood as limiting the technical concept, but should be understood as examples of terms used to describe exemplary aspects.

[0091] In addition, in certain cases, the terms may be arbitrarily selected by the applicant, and in this case, their detailed meanings are described herein. Therefore, the terms used in this article should be understood not only based on the term names, but also based on the meanings of the terms and their contents.

[0092] The “X-axis direction”, “Y-axis direction”, and “Z-axis direction” should not be interpreted only by the geometric relationship of being vertical to each other, and may have broader directivities within the range in which the elements of the present disclosure can function functionally.

[0093] In the following description, various example aspects of the present disclosure are described in detail with reference to the accompanying drawings. With respect to the reference numerals of the elements of each of the accompanying drawings, the same elements may be shown in other drawings, and unless otherwise specified, the same reference numerals may refer to the same elements. The same or similar elements may be represented by the same reference numerals even if they are depicted in different drawings.

[0094] In addition, for ease of description, the proportions, dimensions, sizes and thicknesses of each of the elements shown in the drawings may be different from the actual proportions, dimensions, sizes and thicknesses, and therefore, aspects of the present disclosure are not limited to the proportions, dimensions, sizes and thicknesses shown in the drawings.

However, there may be a problem that the sound of the low-pitched vocal band based on the vibration of the vehicle interior material 130 is not output, and there may be a problem that the flatness of the sound pressure level is reduced, because the number of peaks and declines that appear in the reproduction frequency band of the sound (or sound pressure level) generated based on the vibration of the vehicle interior material 130 increases, and each of the highest sound pressure level and the lowest sound pressure level that appear in the reproduction frequency band of the sound (or sound pressure level) generated based on the vibration of the vehicle interior material 130 increases. The peak may be a phenomenon that the sound pressure level bounces at a specific frequency, and the decline may be a phenomenon that a low sound pressure level is generated as the occurrence of the sound with a specific frequency decreases. The flatness of the sound characteristic may be a deviation level between the highest sound pressure and the lowest sound pressure.

The coupling member 320 may include material properties suitable for blocking (or isolating or reducing) vibration. For example, the coupling member 320 may include a material having elasticity. For example, the coupling member 320 may include a material having elasticity for vibration absorption (or impact absorption). The coupling member 320 according to an embodiment of the present disclosure may be configured as (or include) a polyurethane material and / or a polyolefin material, but the embodiments of the present disclosure are not limited thereto.

[0213] The sound device 30 according to an embodiment of the present disclosure may include a sound generating module 330 having a dual piezoelectric chip structure through a first vibration device 333 and a second vibration device 335, and therefore, the sound characteristics and / or sound pressure level characteristics of the sound including the bass tuning band generated by the sound generating module 330 may be enhanced.

[0214] The sound device for a vehicle and the vehicle device including the sound device according to the embodiment of the present disclosure may further include a connecting member 350. For example, the sound device 30 according to the embodiment of the present disclosure may further include a connecting member 350. The connecting member 350 may be disposed at the rear surface of the housing 310. The connecting member 350 may be disposed or interposed between the housing 310 and the vehicle interior material 130. The vehicle interior material 130 may be connected (or coupled) to the housing 310 by the connecting member 350. For example, the connecting member 350 may be disposed or interposed between the first surface 130s1 of the vehicle interior material 130 and the first housing 311 of the housing 310. For example, the connecting member 350 may be a coupling member, an intermediate member, a buffer member, a pad member, or a vibration transmitting member, but the embodiments of the present disclosure are not limited thereto.

[0215] The connection member 350 may be configured to transfer vibration of the first housing 311 to the vehicle interior material 130 based on vibration of the sound device 330. Therefore, the vehicle interior material 130 may vibrate based on the vibration transferred through the connection member 350 to generate (or output) sound.

[0216] The connection member 350 and the sound device 30 may be completely (or completely) blocked or completely (or completely) hidden by the vehicle interior material 130. Therefore, the connection member 350 and the sound device 30 may be implemented as an invisible or imperceptible structure that is not exposed at all to the interior (or interior space IS) of the vehicle 10 and the exterior of the vehicle 10, and cannot be seen by the eyes of the occupants of the vehicle 10 at all.

[0217] The connecting member 350 may include a material different from that of the first connecting member 321. For example, the connecting member 350 may include a material having an adhesive force different from that of the first connecting member 321. Since the connecting member 350 includes a material having an adhesive force different from that of the first connecting member 321, a separation or disassembly process (or rework) of the connecting member 350 from the vehicle interior material 130 may be easily performed in a separation or disassembly process (or rework) of the sound device 30 attached to the vehicle interior material 130. Therefore, a process of attaching or installing the sound device 30 on the vehicle interior material 130, or a process of separating or disassembling the sound device 30 from the vehicle interior material 130 may be easily performed.

[0218] The connecting member 350 may be coupled (or attached) to the rear surface of the housing 310 and may contact (or surface contact) the first surface 130s1 of the vehicle interior material 130, but the embodiments of the present disclosure are not limited thereto. For example, in the case where the connecting member 350 is coupled (or attached) to the rear surface of the housing 310 and simply contacts (or surface contact) the first surface 130s1 of the vehicle interior material 130, the process of separating or disassembling (or reworking) the connecting member 350 from the vehicle interior material 130 without damaging the sound device 30 or the vehicle interior material 130 can be easily performed in the process of separating and disassembling (or reworking) the sound device 30 from the vehicle interior material 130.

[0219] The connection member 350 according to an embodiment of the present disclosure may include a relatively rigid material (or a hard material). Therefore, the vehicle interior material 130 may vibrate based on the vibration transmitted through the connection member 350 to generate (or output) sound. For example, when the connection member 350 includes a relatively rigid material (or a hard material), the vibration of the first housing 311 may be more effectively transmitted to the vehicle interior material 130.

[0220] The connecting member 350 according to an embodiment of the present disclosure may include rubber, but the embodiments of the present disclosure are not limited thereto. For example, the rubber may be ethylene propylene diene rubber (or ethylene propylene diene M-grade rubber), ethylene propylene rubber, or polyurethane rubber, but the embodiments of the present disclosure are not limited thereto. For example, the ethylene propylene rubber may be ethylene propylene diene monomer (EPDM), but the embodiments of the present disclosure are not limited thereto. For example, the hardness of EPDM may be 40 to 90, but the embodiments of the present disclosure are not limited thereto. For example, the tensile strength of EPDM may be 50 kg / cm 2 Up to 200kg / cm 2 , but the embodiments of the present disclosure are not limited thereto. For example, the connecting member 350 may include highly elastic rubber, but the embodiments of the present disclosure are not limited thereto. According to the embodiments of the present disclosure, since the connecting member 350 includes rubber or the like, when the vibration of the housing 310 or the first housing 311 is transmitted to the internal material 130, the loss of vibration can be prevented or minimized, and therefore, the sound characteristics and / or sound pressure level characteristics of the bass tuning band can be further improved.

[0221] According to an embodiment of the present disclosure, the thickness of the connection member 350 may be different from the thickness of at least one of the first coupling member 321 and the second coupling member 322. For example, the thickness of the connection member 350 may be thicker than the thickness of at least one of the first coupling member 321 and the second coupling member 322. The thickness of the connection member 350 may be 0.5 mm or more, but the embodiment of the present disclosure is not limited thereto. For example, the thickness of the connection member 350 may be 0.5 mm to 3 mm, but the embodiment of the present disclosure is not limited thereto.

[0222] The vehicle interior material 130 according to another embodiment of the present disclosure may include Figure 4 , a meandering portion (or at least one or more bends) 134 shown by a dotted line in FIG. For example, the vehicle interior material 130 may include a vibration region that is vibrated by the sound device 30 (or a connection region (or coupling region) connected (or coupled) to the sound device 30). The vibration region of the vehicle interior material 130 may include a meandering portion (or one or more bends) 134 and one or more planar portions.

[0223] The connection member 350 according to an embodiment of the present disclosure may include a relatively soft material (or a smooth material) for connection (or coupling) with the vehicle interior material 130 including the curved portion 134 and the planar portion. For example, when the curved portion (or one or more curved portions) 134 includes a vibration area of ​​the vehicle interior material 130, the connection member 350 may include a relatively soft material (or a smooth material). For example, the connection member 350 including a relatively soft material (or a smooth material) according to another embodiment of the present disclosure may be a ductile member or a soft member.

[0224] The connecting member 350 may contact the entire vibration area of ​​the vehicle interior material 130. The connecting member 350 may directly contact the entire vibration area of ​​the vehicle interior material 130. For example, the connecting member 350 may directly contact the entire vibration area of ​​the vehicle interior material 130 without a medium or an intermediate member. The vibration generated by the sound generation module 330 may be transmitted to the entire vibration area of ​​the vehicle interior material 130 including the curved portion 134 and the flat portion through the connecting member 350, and therefore, sound may be generated (or output) based on the vibration of the entire vibration area of ​​the vehicle interior material 130, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the vocal cords including the low-pitched vocal cords generated by the sound generation module 330.

The connection member 350 may be filled in the tortuous portion 134 of the vehicle interior material 130, or may be configured to cover or completely cover the tortuous portion 134 of the vehicle interior material 130. For example, the connection member 350 may be filled into the concave portion of the tortuous portion 134, or may be configured to fully (or completely) cover or surround the convex portion of the tortuous portion 134. Therefore, the connection member 350 according to another embodiment of the present disclosure may be filled in the tortuous portion 134 of the vehicle interior material 130, and / or may cover the tortuous portion 134 of the vehicle interior material 130, and may absorb external impact, thereby protecting the sound device 30 from the impact of external impact.

For example, the line portion 340 may be configured to pass through one side surface of each of the first housing 311 and the second housing 312 of the housing 310. For example, the line portion 340 may be configured to pass through one side surface of each of the side wall portions 311b of the first housing 311 and the side wall portions 312b of the second housing 312. The line portion 340 may be a lead-out hole of a signal cable connected to each of the first vibration device 333 and the second vibration device 335 of the vibration device.

The fixing portion 317 may be supported by the hook member 513 of the supporting portion 500 or fixed to the hook member 513. The fixing portion 317 may be coupled to the coupling protrusion 515 of the hook member 513. The coupling protrusion 515 of the hook member 513 may contact the upper surface of the fixing portion 317, and thus, the fixing portion 317 may be disposed (or inserted) or fixed between the vehicle interior material 130 and the coupling protrusion 515.

The first fixing portion 317a may be configured at a first side of the plate 311a and the side wall portion 311b of the first housing 311. For example, the first fixing portion 317a may extend (or protrude) from the first side of the plate 311a and the side wall portion 311b of the first housing 311 along the first direction X to have a certain length. For example, the first fixing portion 317a may extend (or protrude) from the first short side of the first housing 311 along the first direction X to have a certain length. The first fixing portion 317a may be provided as a whole with the first side of the first housing 311.

The second fixing portion 317b may be arranged at the second side of the plate 311a and the side wall portion 311b of the first housing 311. For example, the second fixing portion 317b may extend (or protrude) from the second side of the plate 311a and the side wall portion 311b of the first housing 311 along the first direction X to have a certain length. For example, the second fixing portion 317b may extend (or protrude) from the second short side of the first housing 311 along the first direction X to have a certain length. The second fixing portion 317b may be arranged to be integral with the second side of the first housing 311.

[0356] According to an embodiment of the present disclosure, the first fixing portion 317a may be a first peripheral portion of the first housing 311. The second fixing portion 317b may be a second peripheral portion of the first housing 311 opposite to the first peripheral portion. For example, the first fixing portion 317a may be a first peripheral portion of the first housing 311 adjacent to the first short side. The second fixing portion 317b may be a second peripheral portion of the first housing 311 adjacent to the second short side. Therefore, the first peripheral portion and the second peripheral portion of the first housing 311 may pass through the short side of the vibration member 331 or the short side of the second housing 312, and may extend (or protrude) along the first direction X. The first housing 311 may have a size greater than the size of each of the second housing 312 or the vibration member 331. The first housing 311 may have a size greater than the size of each of the vibration member 331 and the second housing 312 by the size of the first peripheral portion (or the first fixing portion 317a) and the second peripheral portion (or the second fixing portion 317b). For example, the short side length of the first housing 311 may be equal to the short side length of each of the vibration member 331 and the second housing 312 relative to the second direction Y. The long side length of the first housing 311 may be greater than the long side length of each of the vibration member 331 and the second housing 312 relative to the first direction X.

[0357] Based on the hook coupling method, the first fixing portion 317a may be coupled to the first supporting member 510 of the supporting portion 500, and the first supporting member 510 is coupled (or attached) to the vehicle interior material 130 adjacent to the first side of the first housing 311.

The first fixing portion 317a may be coupled to the coupling protrusion 515 at the hook member 513 of the first supporting member 510. The coupling protrusion 515 at the hook member 513 of the first supporting member 510 may contact the upper surface of the first fixing portion 317a, and thus, the first fixing portion 317a may be disposed (or inserted) or fixed between the vehicle interior material 130 and the coupling protrusion 515.

[0358] According to an embodiment of the present disclosure, a distance L1 between the coupling protrusion 515 of the first supporting member 510 and the first surface 130s1 of the vehicle interior material 130 may be smaller than a distance between an upper surface of the first shell 311 (or an upper surface of the first fixing portion 317a) and the first surface 130s1 of the vehicle interior material 130. For example, the distance L1 between the coupling protrusion 515 of the first supporting member 510 and the first surface 130s1 of the vehicle interior material 130 may be smaller than the sum of the thickness of the first shell 311 and the thickness of the connecting member 350. Based on the hook coupling method, the coupling protrusion 515 of the first supporting member 510 may be coupled to the upper surface of the first fixing portion 317a at the first shell 311. Therefore, the first fixing portion 317a at the first shell 311 may be pressed between the coupling protrusion 515 of the first supporting member 510 and the first surface 130s1 of the vehicle interior material 130 by the pressing (or elasticity) of the connecting member 350 and fixed. Therefore, the first support member 510 may support (or fix) the first peripheral portion of the first case 311 while surrounding the first short side of the first case 311 .

[0359] Based on the hook coupling method, the second fixing portion 317b may be coupled to the second supporting member 520 of the supporting portion 500, and the second supporting member 520 is coupled (or attached) to the vehicle interior material 130 adjacent to the second side of the first housing 311 relative to the first side. The second fixing portion 317b may be supported by or fixed to the second supporting member 520. The second fixing portion 317b may be supported by or fixed to the hook member (or second hook member) 513 of the second supporting member 520. The second fixing portion 317b may be coupled to the coupling protrusion 515 at the hook member 513 of the second supporting member 520. The coupling protrusion 515 at the hook member 513 of the second supporting member 520 may contact the upper surface of the second fixing portion 317b, and therefore, the second fixing portion 317b may be disposed (or inserted) or fixed between the vehicle interior material 130 and the coupling protrusion 515.

[0360] According to an embodiment of the present disclosure, the distance L1 between the coupling protrusion 515 of the second supporting member 520 and the first surface 130s1 of the vehicle interior material 130 may be smaller than the distance between the upper surface of the first shell 311 (or the upper surface of the second fixing portion 317b) and the first surface 130s1 of the vehicle interior material 130. For example, the distance L1 between the coupling protrusion 515 of the second supporting member 520 and the first surface 130s1 of the vehicle interior material 130 may be smaller than the sum of the thickness of the first shell 311 and the thickness of the connecting member 350. Based on the hook coupling method, the coupling protrusion 515 of the second supporting member 520 may be coupled to the upper surface of the second fixing portion 317b at the first shell 311. Therefore, the second fixing portion 317b at the first shell 311 may be pressed between the coupling protrusion 515 of the second supporting member 520 and the first surface 130s1 of the vehicle interior material 130 by the pressing (or elasticity) of the connecting member 350 and fixed. Therefore, the second support member 520 may support (or fix) the second peripheral portion of the first case 311 while surrounding the second short side of the first case 311 .

[0361] 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 a spacing corresponding to the long side length of the sound device 30, and can be hook-coupled to each of the first fixing portion 317a and the second fixing portion 317b at the first shell 311 based on a hook coupling method, and thus, the sound device 30 can be supported (or fixed) and the sound device 30 can be connected (or coupled or contacted) to the first surface 130s1 of the vehicle interior material 130. For example, the first shell 311 at the sound device 30 can be inserted (or set) between the first supporting member 510 and the second supporting member 520, and can be hook-coupled to the coupling protrusion 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 protrusion 515 at the hook member 513, and can be connected (or coupled or contacted) to the first surface 130s1 of the vehicle interior material 130. Therefore, based on the hook coupling method using the hook member 513, the coupling process between the sound device 300 and the vehicle structure can be easily performed. Based on the hook coupling method, the process of attaching or installing the sound device 30 on the vehicle interior material 130 and / or the process of disassembling or separating the sound device 30 on the vehicle interior material 130 can be easily performed.

For example, the second electrode portion 1311c may have the same shape as the vibration portion 1311a, but embodiments of the present disclosure are not limited thereto.

[0402] According to an embodiment of the present disclosure, in order to prevent an 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 may be formed at the remaining portion except for the peripheral portion of the vibration portion 1311a.

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

[0408] The second cover member 1315 may be disposed at the second surface of the vibration generating portion 1311.

For example, one or more of the first adhesive layer 1317 and the second adhesive layer 1319 may be configured to partially or completely surround the vibration generating part 1311.

[0414] Either the first cover member 1313 or the second cover member 1315 may be Figures 3 to 28 Adhesive members 332 and 334 are shown connected or coupled to vibration member 331 .

[0415] The vibration generator 1310 according to an embodiment of the present disclosure may further include a signal supply member 1320 .

[0416] The signal supply member 1320 may be configured to supply a driving signal supplied from the driving circuit portion to the vibration generating portion 1311. The signal supply member 1320 may be configured to be electrically connected to the vibration portion 1311a. The signal supply member 1320 may be configured to be electrically connected to the first electrode portion 1311b and the second electrode portion 1311c of the vibration generating portion 1311.

[0417] A portion of the signal supply member 1320 may be accommodated (or inserted) between the first cover member 1313 and the second cover member 1315. An end portion (or distal portion or one side) of the signal supply member 1320 may be disposed or inserted (or accommodated) between an edge portion (or one peripheral portion) of the first cover member 1313 and an edge portion (or one peripheral portion) of the second cover member 1315. An edge portion of the first cover member 1313 and an edge portion of the second cover member 1315 may accommodate or vertically (or up and down) cover an end portion (or distal portion or one side) of the signal supply member 1320. Therefore, the signal supply member 1320 may be integrated (or configured) as one with the vibration generating portion 1311. Therefore, the sound generating module 330 or the vibration devices 333 and 335 may be implemented (or configured) as a membrane type integrated with the signal supply member 1320. For example, the signal supply member 1320 may be configured as a portion (or a component) with the vibration generating portion 1311, thereby achieving a single material effect. For example, the signal supply member 1320 may 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.

[0418] The signal supply member 1320 according to an embodiment of the present disclosure may include a base member 1321 and a plurality of signal lines 1323a and 1323b. For example, the signal supply member 1320 may include a base member 1321, a first signal line 1323a, and a second signal line 1323b.

[0419] The base member 1321 may include a transparent or opaque plastic material, but the embodiments of the present disclosure are not limited thereto. The base member 1321 may have a certain width along the first direction X, and may extend long along a second direction Y intersecting the first direction X.

[0420] The first signal line 1323a and the second signal line 1323b may be disposed at a first surface of the base member 1321 parallel to the second direction Y, and may be spaced apart from each other or electrically separated from each other along the first direction X. The first signal line 1323a and the second signal line 1323b may be disposed parallel to each other at the first surface of the base member 1321. For example, the first signal line 1323a and the second signal line 1323b may be implemented in a line shape by patterning a metal layer (or a conductive layer) formed or deposited at the first surface of the base member 1321.

[0421] End portions (or distal portions or one side) of the first signal line 1323 a and the second signal line 1323 b may be separated from each other and thus may be individually bent or curved.

[0422] The end portion (or distal portion or one side) of the first signal line 1323a may be electrically connected to the first electrode portion 1311b of the vibration generating portion 1311. For example, the end portion of the first signal line 1323a may be electrically connected to at least a portion of the first electrode portion 1311b of the vibration generating portion 1311 in one edge portion of the first cover member 1313. For example, the end portion (or distal portion or one side) of the first signal line 1323a may be electrically connected and directly connected to at least a portion of the first electrode portion 1311b of the vibration generating portion 1311. For example, the end portion (or distal portion or one side) of the first signal line 1323a may be electrically connected to or directly contact the first electrode portion 1311b of the vibration generating portion 1311. For example, the end portion of the first signal line 1323a may be electrically connected to the first electrode portion 1311b by a conductive double-sided tape. Therefore, the first signal line 1323 a may be configured to transfer the first driving signal supplied from the driving circuit portion (or the vibration driver) to the first electrode portion 1311 b of the vibration generating portion 1311 .

[0423] The end portion (or distal portion or one side) of the second signal line 1323b can be electrically connected to the second electrode portion 1311c of the vibration generating unit 1311. For example, the end portion of the second signal line 1323b can be electrically connected to at least a portion of the second electrode portion 1311c of the vibration generating unit 1311 in one edge portion of the second cover member 1315. For example, the end portion of the second signal line 1323b can be electrically connected and directly connected to at least a portion of the second electrode portion 1311c of the vibration generating unit 1311. 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 unit 1311. For example, the end portion of the second signal line 1323b can be electrically connected to the second electrode portion 1311c of the vibration generating unit 1311 by a conductive double-sided tape. Therefore, the second signal line 1323b can be configured to transfer the second drive signal supplied from the drive circuit unit (or vibration driver) to the second electrode portion 1311c of the vibration generating unit 1311.

[0424] The signal supply member 1320 according to an embodiment of the present disclosure may further include an insulating layer 1325 .

[0425] The insulating layer 1325 may be disposed at the first surface of the base member 1321 to cover each of the first signal line 1323 a and the second signal line 1323 b except for an end portion (or one side) of the signal supply member 1320 .

[0426] An end portion (or one side) of the signal supply member 1320 including an end portion (or one side) of the base member 1321 and an end portion (or one side) 1325a of the insulating layer 1325 may be inserted (or accommodated) between the first cover member 1313 and the second cover member 1315, and may be fixed between the first cover member 1313 and the second cover member 1315 by the first adhesive layer 1317 and the second adhesive layer 1319. Therefore, an end portion (or one side) of the first signal line 1323a may remain electrically connected to the first electrode portion 1311b of the vibration generating portion 1311, and an end portion (or one side) of the second signal line 1323b may remain electrically connected to the second electrode portion 1311c of the vibration generating portion 1311. In addition, an 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.

[0427] In the signal supply member 1320 according to the 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 insulating 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 to the outside without being supported or covered by each of the end portion (or one side) 1325a of the base member 1321 and the end portion (or one side) 1325a of the insulating 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) from the end portion 1321e of the base member 1321 or the end portion 1325e of the insulating layer 1325 to have a certain length. Therefore, each of the end portion (or distal portion or one side) of each of the first signal line 1323a and the second signal line 1323b can be bent individually or independently.

[0428] An end portion (or one side) of the first signal line 1323a that is not supported by an end portion (or one side) of the base member 1321 and an end portion 1325a of the insulating layer 1325 may be directly connected to or directly contact the first electrode portion 1311b of the vibration generating portion 1311. An end portion (or one side) of the second signal line 1323b that is not supported by an end portion (or one side) of the base member 1321 and an end portion 1325a of the insulating layer 1325 may be directly connected to or directly contact the second electrode portion 1311c of the vibration generating portion 1311.

[0429] According to an embodiment of the present disclosure, a portion of the signal supply member 1320 or a portion of the base member 1321 may 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 may be integrated (or configured) as one body with the vibration generating part 1311. Therefore, the vibration generating part 1311 and the signal supply member 1320 may be configured as one part (or one component), and thus, a single material effect may be obtained.

[0430] 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 may be integrated (or configured) as one body with the vibration generator 1310, and thus, a welding process for electrical connection between the vibration generator 1310 and the signal supply member 1320 may not be required. Therefore, the manufacturing process and structure of the vibration devices 333 and 335 may be simplified, and the danger associated with the welding process may be reduced.

[0431] The signal supply component 1320 may be provided by Figure 3 , Figure 5 , Figure 7 , Fig. 9 , Fig.11 , Fig.13 , Fig.15 and Figures 18 to 28 The illustrated line portion 340 is unloaded to the outside, and is electrically connected to the driving circuit portion.

[0438] According to an embodiment of the present disclosure, each of the plurality of second parts 1311a2 can absorb the impact applied to the first part 1311a1, and thus can enhance the overall durability of the first part 1311a1 and provide flexibility to the vibration part 1311a.
