[0001] Cross-reference to related applications

[0002] This application claims priority from Korean Patent Application No. 10-2023-0078511 filed in Korea on Jun. 19, 2023, which is hereby expressly incorporated by reference into this application in its entirety. Technical Field

[0003] The present disclosure relates to a sound device and a vehicle device including the sound device. Background Art

[0004] The vehicle includes a sound device that outputs sound based on an audio signal output from a multimedia device, and such a sound device may include a car audio device. For example, the sound device applied to the vehicle may include front and rear speakers configured as coil-type devices. Summary of the Invention

[0005] However, vehicle audio equipment may be limited by the limitations of coil-type devices when outputting realistic sound or multi-channel stereo sound through front and rear speakers. Furthermore, while increasing the number of speakers in vehicle audio equipment can produce stereo sound, increasing the number of speakers is limited due to the size of the coil-type speakers and space constraints in the vehicle, making it impossible to provide realistic sound or stereo sound using a compact and aesthetically pleasing coil-type device.

[0006] The inventors of the present disclosure have recognized the problems and shortcomings of the related art and have conducted extensive research and experiments to enhance the sound characteristics and / or sound pressure level characteristics of a sound device for a vehicle. Based on the extensive research and experiments, the inventors have invented a sound device that can enhance the sound characteristics and / or sound pressure level characteristics and a vehicle device including the sound device.

[0081] 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

[0082] Reference will now be 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 known functions, structures, or configurations may unnecessarily obscure aspects of the present disclosure, a detailed description of such known methods, functions, or configurations may be omitted for the sake of brevity. Furthermore, for the sake of brevity, repeated descriptions may be omitted. The described progression of processing steps and / or operations is a non-limiting example.

[0083] 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 specific 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 a different order depending on the functions or operations involved.

[0084] Unless otherwise stated, even if the same reference numerals are shown in different drawings, 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 drawings 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.

[0085] The advantages and features of the present disclosure and their implementation methods are illustrated by various aspects described with reference to the accompanying drawings. However, the present disclosure may be embodied in different forms and should not be construed as limited to the exemplary aspects set forth herein. Rather, these exemplary aspects are examples and are provided so that the present disclosure may be thorough and complete, to aid those skilled in the art in understanding the inventive concept, and not to limit the scope of protection of the present disclosure.

[0086] The shapes, dimensions (e.g., size, length, width, height, thickness, position, radius, diameter, and area), proportions, ratios, angles, numerals, number of elements, etc. disclosed herein, including those shown in the accompanying drawings, are merely examples, and therefore, the present disclosure is not limited to the details shown. However, it should be noted that the relative sizes of the components shown in the drawings are part of the present disclosure.

[0087] 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, parts, components, parts, areas, sections, steps, operations, etc.), one or more other elements may be added unless terms such as "only" are used. The terms used in this disclosure are only for describing example aspects and are not intended to limit the scope of this disclosure. Unless the context clearly indicates otherwise, terms in the singular may include plural forms.

[0088] Unless otherwise stated, the word "exemplary" is used to mean serving as an example or illustration. An embodiment is an example embodiment. An aspect is an example aspect. In one or more implementations, "embodiment," "aspect," "example," etc. should not be construed as preferred or preferable 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. Furthermore, the term "may" encompasses all meanings of the term "can."

[0089] In one or more aspects, unless otherwise expressly stated, elements, features, or corresponding information (e.g., levels, ranges, dimensions, sizes, etc.) are interpreted as including an error or tolerance range, even if no explicit description of such an error or tolerance range is provided. Errors or tolerance ranges 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.

[0090] When describing a positional relationship, when two components (e.g., layers, films, regions, components, sections, etc.) are described using, for example, “on,” “over,” “on top of,” “over,” “under,” “above,” “below,” “near,” “near,” “adjacent,” “beside,” “nearby,” “on 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,” “directly,” or “close to” are used. For example, when a structure is described as being positioned relative to another structure as follows: When referring to positions: "on...", "over...", "on top of...", "above...", "below...", "above", "below", "beneath...", "near", "near", "beside", "nearby", "to the side or on", etc., the description should be interpreted to include the case where the structures are in contact with each other and the case where one or more additional structures are disposed or interposed 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.

[0091] Spatially relative terms such as "below," "beneath," "lower," "above," "upper," etc. may be used to describe the relationship 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 turned over, 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, can include all directions of "above" and "below." Likewise, the exemplary terms "above" or "up" can include both directions of "above" and "below."

[0092] 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 therefore one or more other events may occur in between, unless more restrictive terms such as "just after", "immediately" or "directly" are used.

[0093] 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.

[0094] It should be understood that although the terms "first", "second" etc. can be used to describe various elements (for example, layer, film, region, component, section, member, portion, region, district, part, step, operation, etc.) in this article, these elements should not be limited by these terms, for example, not subject to 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 this disclosure, the first element can represent the second element, and similarly, the second element can represent the first element. In addition, without departing from the scope of this 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 (for example, 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 can include one or more first elements. Similarly, the second element, etc. can include one or more second elements, etc.

[0095] 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 are not used to limit the nature, basis, sequence, order, or number of the elements.

[0096] When an element (for example, a layer, film, region, component, 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.

[0097] When an element (e.g., a layer, film, region, component, section, etc.) is “in contact with,” “overlapped with,” etc., 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., by having one or more intervening elements disposed between or inserted into the elements.

[0098] Phrases where an element (e.g., a layer, film, region, component, section, etc.) is “provided”, “disposed”, “provided”, “disposed” on, “connected”, “coupled” to, or “connected” to another element, etc., can be understood to mean, for example, that at least a portion of the element is provided in, disposed in, disposed on, connected to, coupled to, or connected to a portion of another element, or that the entire element is provided in, disposed on, connected to, coupled to, or connected to another element. Phrases where an element (e.g., a layer, film, region, component, section, etc.) “contacts”, “overlaps”, or the like with another element can be understood to mean, for example, that at least a portion of the element contacts, overlaps, or the like with at least a portion of another element, that the entire element contacts, overlaps, or the like with at 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, etc.

[0099] 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 such as "first direction", "second direction", etc., such as directions parallel to 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 a wider range of directivity within which the components of the present disclosure can operate functionally.

[0100] 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 items" 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.

[0101] The expression "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); 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. In addition, the expression "A / B" can be understood as A and / or B. For example, the expression "A / B" can refer to only A; only B; A or B; or A and B.

[0102] In one or more aspects, unless otherwise indicated, for convenience, the terms "between" and "wherein" can be simply used interchangeably. For example, the expression "between a plurality of elements" can be understood as in a plurality of elements. In another example, the expression "in 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. 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 can also be present.

[0103] In one or more aspects, unless otherwise specified, for convenience, the phrases "one another" and "mutually" may be used interchangeably. For example, the expression "different from each other" may be understood to mean different from each other. In another example, the expression "different from each other" may be understood to mean different from each other. In one or more examples, the number of elements involved in the foregoing expression may be two. In one or more examples, the number of elements involved in the foregoing expression may be more than two.

[0104] In one or more aspects, the phrases "one or more of" and "one or more of" may be used interchangeably for convenience unless otherwise indicated.

[0105] The term "or" means an inclusive or, not 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."

[0106] The feature of the various aspects of the present disclosure can be coupled to each other or combined in part or in its entirety, can be associated with each other technically, and can operate, link or drive together in various ways.Aspects of the present disclosure can be realized or performed independently of each other, or can be realized or performed together with a common dependency or relevant relationship.In one or more aspects, the parts of each equipment according to the various aspects of the present disclosure can be operationally coupled and configured.

[0107] Unless otherwise defined, the terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one 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 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.

[0108] The terms used herein have been selected as commonly used terms in the relevant technical field; however, other terms may exist based on the development and / or changes in technology, conventions, preferences of technicians, etc. Therefore, the terms used herein should not be understood as limiting the technical concepts, but should be understood as examples of terms used to describe exemplary aspects.

[0109] In addition, in certain cases, the terms may be arbitrarily selected by the applicant, and in such cases, their detailed meanings are described herein. Therefore, the terms used herein should be understood not only based on the term names but also based on the meanings and contents of the terms.

[0110] 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 directionality within the range in which the elements of the present disclosure can functionally function.

[0111] In the following description, various exemplary aspects of the present disclosure are described in detail with reference to the accompanying drawings. With respect to the reference numerals of the elements in each of the 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.

[0112] 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.

[0178] The vibration member 331 may be disposed or configured in the area between the first shell 311 and the second shell 312 of the housing 310. The vibration member 331 may be configured to divide the internal space 313 of the housing 310 into a first space 313a and a second space 313b. For example, the internal space 313 of the housing 310 may be divided into a first space 313a and a second space 313b by the vibration member 331.

For example, the internal space 313 may be a gap space, an air gap, an air space, a vibration space, a sound space, a sound box, a sealed space, etc., but embodiments of the present disclosure are not limited thereto.

[0181] The sound generation module 330 can generate a sound pressure level (or sound or sound waves) in the interior space 313 of the housing 310 to vibrate the housing 310, and can vibrate the vehicle interior material 130 based on the vibration of the housing 310. For example, the sound generation module 330 can be configured to vibrate the first shell 311 of the housing 310 to vibrate the vehicle interior material 130. For example, the sound generation module 330 can generate a sound pressure level (or sound or sound waves) in the interior space 313 of the housing 310 to vibrate the first shell 311, and can vibrate the vehicle interior material 130 based on the vibration of the first shell 311.

[0182] According to an embodiment of the present disclosure, the first housing 311 may include an opening portion 310 o .

[0183] The opening portion 310o can be configured to pass through (or vertically pass through) the first shell 311 along the thickness direction Z (or vertical direction) of the shell 310. The opening portion 310o can be connected to the internal space 313 (or communicate with the internal space 313). For example, the opening portion 310o can be connected to the first space 313a (or communicate with the first space 313a). For example, the opening portion 310o can be configured to reduce the air pressure of the internal space 313 of the shell 310. For example, the opening portion 310o can be configured to reduce the air pressure of the first space 313a. The opening portion 310o can be configured to reduce the air pressure of the first space 313a of the first shell 311 or the air pressure of the first space 313a provided between the vibration member 331 and the first shell 311. Therefore, the frequency band of the low-pitched vocal band can be expanded, and thus the sound characteristics of the low-pitched vocal band can be improved. Since the pressure (or air pressure) of the first space 313a is reduced by the opening 310o, the displacement (or bending force) of the first vibration device 333 provided between the vibration member 331 and the first housing 311 can be increased, and thus, the frequency band of the low-pitched vocal band can be expanded, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band. Therefore, the sound characteristics (or sound pressure level) of the low-pitched vocal band generated based on the vibration of the first vibration device 333 and / or the second vibration device 335 can be improved.

[0184] According to an embodiment of the present disclosure, the opening 310o may be provided to correspond to the center portion of the sound generating module 330. For example, the opening 310o may be provided to correspond to the vibration devices 333 and 335.

For example, the opening 310o may be provided to correspond to the center portion of each of the first vibration device 333 and the second vibration device 335. For example, the interior space 313 of the housing 310 may include a space connected to the opening 310o. For example, the interior space 313 of the housing 310 may include a first space 313a connected to the opening 310o.

For example, the opening portion 310o may include a linear shape having a size (or length) smaller than the first vibration device 333 provided at the vibration member 331. For example, the opening portion 310o may be a hole, a slot, or a slit, but embodiments of the present disclosure are not limited thereto. For example, the opening portion 310o may be a sound emission portion, a first sound emission port, a sound output portion, a sound output port, a sound output hole, or a vent, but embodiments of the present disclosure are not limited thereto.

[0186] The opening portion 310o may be a space through which sound waves generated based on the vibration of the sound generating module 330 propagate (or are transmitted) to the interior space IS of the vehicle 10. For example, the vibration of the sound generating module 330 may be transmitted to the interior space IS of the vehicle 10 through the opening portion 310o. For example, the sound waves (or sounds) generated based on the vibration of the sound generating module 330 may be transmitted (or output or emitted) to the interior space IS of the vehicle 10 through the opening portion 310o. Therefore, the vibration width (or displacement width) of the vibration member 331 based on the vibration of the sound generating module 330 may be increased, and thus, the sound characteristics and / or sound pressure level characteristics generated based on the vibration of the vibration member 331 may be enhanced.

[0187] The first housing 311 including the opening 310o can be disposed closer to the vehicle interior material 130 than the second housing 312. For example, the first housing 311 including the opening 310o can be disposed closer to the vehicle interior material 130 than the second housing 312. Therefore, the sound generated based on the vibration of one or more of the first vibration device 333 and the second vibration device 335 can be output to the interior space IS of the vehicle 10, and thus, the sound including the low-pitched vocal range can be output to the interior space IS of the vehicle 10.

[0188] The first shell 311 may include a sloped surface (or inclined surface or deflected surface) 311s and an inner surface 311i.

The sloped surface 311s may be configured to guide the sound generated based on the vibration of the sound generating module 330 to the inner space IS of the vehicle 10. Therefore, the sound generated based on the vibration of the sound generating module 330 can be output to the inner space IS of the vehicle 10, and the sound characteristics and / or sound pressure level characteristics of the sound including the low-pitched vocal band can be further enhanced. For example, the sloped surface 311s may be a guide surface or a sound guiding surface, 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 380 may include high-elasticity rubber or low-elasticity rubber, but the embodiments of the present disclosure are not limited thereto. According to the embodiments of the present disclosure, because the connecting member 380 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 vibration loss can be prevented or minimized, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be further improved.

[0369] According to an embodiment of the present disclosure, the first coupling member 321 and the second coupling member 322 of the coupling member 320 may include an adhesive, a double-sided tape, a double-sided adhesive tape, a double-sided foam tape, a double-sided adhesive foam tape, a double-sided pad, a double-sided foam pad, a double-sided adhesive foam pad, a double-sided pad member, a double-sided buffer member, a double-sided buffer pad or a double-sided buffer tape, etc., but the embodiment of the present disclosure is not limited thereto.

[0370] According to an embodiment of the present disclosure, the connection member 380 may include a material different from that of the first adhesive member 332 and the second adhesive member 334. For example, the first adhesive member 332 and the second adhesive member 334 may include an adhesive, a double-sided tape, a double-sided adhesive tape, a double-sided adhesive foam tape, a double-sided pad, a double-sided foam pad, a double-sided adhesive foam pad, a double-sided buffer tape, or an adhesive sheet, but embodiments of the present disclosure are not limited thereto.

[0371] According to an embodiment of the present disclosure, the connection member 380 may further include a hole 380 o (or a fourth hole or an opening hole). For example, the connection member 380 may further include a hole 380 o connected to the opening portion 310 o in the housing 310 or the first housing 311 .

[0372] The hole 380o can be arranged to correspond to (or overlap) the opening portion 310o. The hole 380o can have the same shape as the opening portion 310o, but the embodiments of the present disclosure are not limited thereto. For example, the hole 380o can have the same shape as the opening portion 310o, and can have a size larger than the size of the opening portion 310o. Therefore, the sound based on the vibration of the sound generating module 330 can be output to the interior space IS of the vehicle through (or with the help of) the opening portion 310o and the hole 380o. For example, the hole 380o can be an opening portion, an opening hole, a slit, a groove, a connecting hole or an intermediate hole, but the embodiments of the present disclosure are not limited thereto.

[0373] According to an embodiment of the present disclosure, the hole 380o may correspond to (or overlap) the hole 135 of the vehicle interior material 130. The hole 380o may be between the hole 135 of the vehicle interior material 130 and the opening 310o of the housing 310. For example, the hole 380o may be between the hole 135 of the vehicle interior material 130 and the opening 310o of the first housing 311. The hole 380o may be connected to the opening 310o of the housing 310. For example, the hole 380o may be connected to the opening 310o of the first housing 311. The hole 380o may be provided to correspond to the opening 310o. The hole 380o of the connecting member 380 may have the same size as each of the opening 310o and the hole 135, or may have a size larger than each of the opening 310o and the hole 135. Therefore, the sound based on the vibration of the sound generation module 330 may be output to the interior space IS of the vehicle through (or by way of) the opening portion 310 o , the hole 380 o , and the hole 135 .

[0374] Reference Figure 25A and Figure 25B The thickness T1 of the connecting member 380 may differ from the thickness of at least one of the first coupling member 321 and the second coupling member 322. For example, the thickness T1 of the connecting member 380 may be thicker than the thickness of at least one of the first coupling member 321 and the second coupling member 322. The thickness T1 of the connecting member 380 may be 0.5 mm or greater, but embodiments of the present disclosure are not limited thereto. For example, the thickness T1 of the connecting member 380 may be 0.5 mm to 3 mm, but embodiments of the present disclosure are not limited thereto. For example, the connecting member 380 may have a thickness T1 obtained by compressing the initial thickness T1′ using the coupling force between the coupling portion 500 and the first housing 311. Therefore, based on the coupling force between the coupling portion 500 and the first housing 311, the connecting member 380 may come into surface contact with the vehicle interior material 130 including at least one or more curved portions 136.

[0375] According to another embodiment of the present disclosure, the connecting member 380 may have a compressive force (or contractile force) and an elastic restoring force, and may be contracted or compressed by coupling between the coupling portion 500 and the first housing 311. The length (or thickness) of the connecting member 380 may be less than or equal to the length (or thickness) of the vehicle interior material 130. For example, the length (or thickness) of the connecting member 380 may be less than or equal to the length (or thickness) of the first housing 311.

[0376] like Figure 25B As shown, the connecting member 380 may have an initial thickness T1′ before being compressed (or contracted), and may be compressed (or contracted) to have a thickness T1′ based on the pressure applied from the housing 310 through the coupling (or connection) between the coupling portion 500 and the housing 310. Figure 25A The deformed thickness (or compressed thickness) T1 shown. For example, when the sound device 30 is connected to the vehicle interior material 130 via the coupling portion 500, or when assembly and / or rework are completed, the thickness of the connecting member 380 can be compressed from the initial thickness T1' to the compressed thickness T1, and thus, the vibration of the housing 310 can be effectively transmitted to the vehicle interior material 130. For example, when the sound device 30 is separated (or removed) from the vehicle interior material 130 by removing the coupling portion 500, the connecting member 380 can be restored from the deformed thickness (or compressed thickness) T1 to the initial thickness T1' by elastic restoring force.

[0377] Reference Figure 25A and Figure 25B , the coupling portion 500 can be connected or coupled to the sound device 30 through the second hole 135 of the vehicle interior material 130, the hole 380o of the connecting member 380, and the opening 310o of the first housing 311 (arrow direction). For example, in the interior space of the vehicle, the coupling portion 500 can be connected or coupled to the opening 310o of the first housing 311 through the second hole 135 of the vehicle interior material 130 and the hole 380o of the connecting member 380. According to an embodiment of the present disclosure, in the interior space of the vehicle, the coupling portion 500 can be connected or coupled to the sound device 30 or the housing 310 through the hole 135 of the vehicle interior material 130 (arrow direction). For example, in the interior space of the vehicle, the coupling portion 500 can be accommodated or inserted into the hole 380o of the connecting member 380 and the opening 310o of the first housing 311 through the hole 135 of the vehicle interior material 130. For example, the hook member 504 of the coupling portion 500 may be connected or coupled to the opening portion 310o of the first housing 311. For example, the hook member 504 of the coupling portion 500 may be inserted (or received) into the opening portion 310o of the first housing 311 and may be connected or coupled to the slope surface 311s of the first housing 311 through a hook coupling scheme.

[0379] Reference Figure 25C , a vehicle interior material 130 according to another embodiment of the present disclosure may include at least one or more curved portions (or tortuous portions) 136. A connecting member 380 may be configured to correspond to the at least one or more curved portions 136. The connecting member 380 may be in contact with the at least one or more curved portions 136. The connecting member 380 may be in direct contact with the at least one or more curved portions 136. For example, the connecting member 380 may be in direct contact with the at least one or more curved portions 136 without an intermediary or intermediate member.

[0380] The sound device 30 or the housing 310 can be connected or coupled to at least one or more curved portions 136 of the vehicle interior material 130 via a connecting member 380. For example, the connecting member 380 can be disposed between the housing 310 and at least one or more curved portions 136 of the vehicle interior material 130. For example, the connecting member 380 can be disposed between the first housing 311 and at least one or more curved portions 136 of the vehicle interior material 130. For example, the first housing 311 can be connected or coupled to at least one or more curved portions 136 of the vehicle interior material 130 via a connecting member 380.

[0381] According to an embodiment of the present disclosure, the sound based on the vibration of the sound generating module 330 can be output to the interior space of the vehicle through (or with the aid of) the opening portion 310o, the hole 380o, and the second hole 135. In addition, the vibration of the housing 310 or the first housing 311 based on the sound (or sound pressure level, or sound wave) based on the vibration of the sound generating module 330 can be effectively transmitted to the vehicle interior material 130 including at least one or more curved portions 136 through the connecting member 380 without vibration loss, and the vehicle interior material 130 including at least one or more curved portions 136 can vibrate based on the vibration of the housing 310 or the first housing 311 transmitted through the connecting member 380 to be output to the interior space of the vehicle, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range can be further improved.

[0382] The sound device 30 according to another embodiment of the present disclosure may include a housing 310 and a connecting member 380. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range may be further improved, and the sound generating module 330 attached to the vehicle interior material 130 via the connecting member 380 including a rubber material may be easily attached or detached.

[0383] Figure 26 A sound device according to another embodiment of the present disclosure is shown. Figures 27 to 30 The interior of a sound device according to another embodiment of the present disclosure is shown. Figures 26 to 30 Shown above with reference Figures 1 to 25C The embodiment of the sound device 30 described above is additionally configured with at least one hole. Therefore, in the following description, at least one hole will be described in detail, and other elements may be the same as those described above. Figures 1 to 25C The elements described in the accompanying drawings are substantially the same, and thus, the same reference numerals refer to the same elements, and repeated descriptions are omitted or will be briefly given below.

[0384] Reference Figure 26 , the sound device 30 according to another embodiment of the present disclosure may further include at least one or more holes 331 o.

[0385] At least one or more holes 331o may be configured at the vibration member 331. At least one or more holes 331o may be configured to pass through the vibration member 331.

For example, at least one or more holes 331o may be formed to vertically pass through the vibration member 331 in the thickness direction Z of the vibration member 331.

[0386] The sound generating module 330 according to an embodiment of the present disclosure may include a vibration part 331 having at least one or more holes 331 o and vibration devices 333 and 335 configured at the vibration part 331 .

[0387] The at least one or more holes 331o may be configured to regulate the flow of air in the interior space 313 of the housing 310. For example, the at least one or more holes 331o may control the flow of air in the interior space 313 of the housing 310, which is spatially separated from each other by the vibration member 331. For example, the at least one or more holes 331o may be configured to regulate the flow of air between a first space 313a and a second space 313b, which are spatially separated from each other by the vibration member 331, in the interior space 313 of the housing 310. For example, the at least one or more holes 331o may be a first hole, a vent, an airflow hole, a vent, a duct hole, a first connection hole, a first communication hole, or a first space connection portion, but embodiments of the disclosure are not limited thereto.

[0388] The at least one or more holes 331 o according to an embodiment of the present disclosure may be configured in a polygonal shape, such as a circular shape, an elliptical shape, or a quadrangular shape, but the embodiment of the present disclosure is not limited thereto.

[0389] At least one or more holes 331o can be configured to reduce the air pressure in the interior space 313 of the housing 310. For example, at least one or more holes 331o can be configured to connect the first space 313a and the second space 313b, which are spatially separated from each other by the vibration member 331, to each other in the interior space 313 of the housing 310. For example, the first space 313a and the second space 313b of the interior space 313 in the housing 310 can be connected to each other (interconnected) through at least one or more holes 331o. For example, at least one or more holes 331o can be configured to reduce the air pressure in the first space 313a of the first housing 311 or the first space 313a provided between the vibration member 331 and the first housing 311. As a result, the frequency band (reproduction frequency band) of the low-pitched vocal range can be expanded, and thus the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range can be improved. In addition, the sound generation module 330 can vibrate more stably through the at least one or more holes 331o in the vibration member 331, and thus, the sound characteristics and / or sound pressure level characteristics can be further improved.

[0390] According to an embodiment of the present disclosure, the internal space 313 may be between the first surface of the sound generating module 330 and the first housing 311 and may be connected to the opening portion 310o. The internal spaces 313 may be connected to each other (interconnected) through at least one or more holes 331o. The housing 311 may include a second space 313b between the second housing 312 and the second surface of the sound generating module 330 opposite to the first surface. The internal space 313 and the second space 313b may be connected to each other (interconnected) through at least one or more holes 331o.

[0391] According to an embodiment of the present disclosure, at least one or more holes 331o may be provided adjacent to the vibration devices 333 and 335. For example, at least one or more holes 331o may be provided at the periphery of each of the vibration devices 333 and 335. For example, at least one or more holes 331o may be provided adjacent to the side surface of each of the vibration devices 333 and 335. For example, the distance between the at least one or more holes 331o and each of the vibration devices 333 and 335 may be smaller than the distance between the at least one or more holes 331o and the side wall (or side surface) of the housing 310. For example, when the at least one or more holes 331o are provided at a position away from each of the vibration devices 333 and 335, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range may be further improved.

[0392] According to an embodiment of the present disclosure, at least one or more holes 331o may be configured at the vibration component 331 adjacent to the vibration devices 333 and 335, with the vibration devices 333 and 335 between them. For example, the vibration member 331 may include a first peripheral area adjacent to the first side surface of each of the vibration devices 333 and 335, and a second peripheral area opposite to the second side opposite to the first side of each of the vibration devices 333 and 335. For example, with respect to the first direction X, the vibration member 331 may include a first peripheral area, a vibration area, and a second peripheral area. For example, in the vibration member 331, each of the first peripheral area and the second peripheral area may be a hole area or a non-arrangement area of ​​each of the vibration devices 333 and 335, and the vibration area may be an arrangement (or setting) area of ​​the vibration devices 333 and 335.

[0393] According to an embodiment of the present disclosure, the vibration devices 333 and 335 each include a long side and a short side. The distance (or separation distance or shortest distance) between the at least one or more holes 331o and the short sides of the vibration devices 333 and 335 may represent a ratio of the length of the short sides of the vibration devices 333 and 335. According to an embodiment of the present disclosure, the distance between the at least one or more holes 331o and the vibration devices 333 and 335 may be 60% or less of the length of the short sides of the vibration devices 333 and 335.

[0394] Reference Figure 26 and Figure 27 , at least one or more holes 331o may be provided closer to the vibration devices 333 and 335 than the coupling member 320. The coupling member 320 may include a first coupling member 321 and a second coupling member 322. For example, at least one or more holes 331o may be provided closer to the vibration devices 333 and 335 than the first coupling member 321 and the second coupling member 322. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range may be enhanced. Figure 48A and Figure 48B Sound output characteristics based on the distance between the vibration devices 333 and 335 and the at least one or more holes 331 o are described.

[0395] Reference Figures 27 to 30, one or more holes 331o may have straight or vertical hole walls so that any polygonal shape has a constant cross-sectional shape. For example, when one or more holes 331o are circular in shape, the cross-section of one or more holes 331o may be cylindrical in shape, but embodiments of the present disclosure are not limited thereto. For example, the hole wall may have a shape that changes from the top (or first) opening to the bottom (or second) opening of one or more holes. In various embodiments of the present disclosure, the top opening may refer to the opening of the hole 331o facing the second shell 312, and the bottom opening may refer to the opening of the hole 331o facing the first shell 311.

[0396] In embodiments of the present disclosure, the shape of the hole wall can narrow from the top opening to the bottom opening or from the bottom opening to the top opening. In various embodiments of the present disclosure, the size or area of ​​the top opening and the bottom opening can be different from each other, but can also be the same. When different, the top opening can be smaller than the bottom opening, or the bottom opening can be smaller than the top opening.

[0397] In various embodiments of the present disclosure, the shape (or width or diameter) of the hole wall can be widest at the top opening and the bottom opening and gradually become smaller towards the middle of the hole 331o, or can be widest in the middle and gradually become smaller towards the top opening and the bottom opening. The change in the width of the hole wall does not have to be gradual, and there can be one or more steps or curves in the hole wall within the hole 331o. In various embodiments of the present disclosure, the cross-sectional shape of the hole wall can be a triangular wave or a curved wave, a concave shape or a convex shape or various combinations thereof, but is not limited thereto. In addition, when there are multiple holes 331o, the cross-sectional shapes of the hole walls can be the same as or different from each other.

[0398] In addition, the second housing 312 may include a hole similar to the opening portion 310 o of the first housing 311 .

[0399] According to an embodiment of the present disclosure, at least one or more holes 331o do not overlap with the opening 310o. For example, at least one or more holes 331o can be set to be spaced apart from the opening 310o. Therefore, the sound generated by the vibration (or driving) of each vibration device 333 and 335 in the second space 313b can be output to the first space 313a through the at least one or more holes 331o, and the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range can be enhanced.

[0400] Reference Figure 26 and Figure 28 , the size of at least one or more holes 331o may be different from Figure 27As the size of the at least one or more holes 331o increases, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range increase. For example, the distance between the at least one or more holes 331o and the vibration devices 333 and 335 can be smaller than the distance between the at least one or more holes 331o and the side wall (or side surface) of the housing 310. For example, as the size of the at least one or more holes 331o increases, the sound pressure level characteristics of the low-pitched vocal range of 400 Hz or lower can be further enhanced. Figure 47A 、 Figure 47B and Figure 49 Sound output characteristics based on the size of at least one or more holes 331o are described.

[0401] Reference Figure 26 and Figure 29 , at least one or more holes 331o may be configured with two holes 331o. For example, the sound device 30 according to an embodiment of the present disclosure may further include two holes 331o. The two holes 331o may be configured adjacent to each other. For example, the two holes 331o may be configured adjacent to the vibration devices 333 and 335. For example, the distance between each of the two holes 331o and the vibration devices 333 and 335 may be different. For example, the two holes 331o may be configured in parallel in the first direction X so as to be adjacent to the vibration devices 333 and 335. For example, the distance between each of the two holes 331o and the vibration devices 333 and 335 may be equal to each other. For example, each of the two holes 331o may be configured adjacent to the vibration devices 333 and 335. For example, the two holes 331o may be configured in parallel in the second direction Y so as to be adjacent to the vibration devices 333 and 335.

[0402] Each of the two holes 331 o according to an embodiment of the present disclosure may be configured in a polygonal shape such as a circular shape, an elliptical shape, or a quadrangular shape, but the embodiment of the present disclosure is not limited thereto.

For example, at least one or more holes 331o may be configured to be adjacent to the vibration devices 333 and 335. Figure 50 Sound output characteristics based on the shape of at least one or more holes 331 o are described.

[0404] Reference Figures 27 to 30, one or more holes 331o may have straight or vertical hole walls so that any polygonal shape has a constant cross-sectional shape. For example, when one or more holes 331o are circular in shape, the cross-section of one or more holes 331o may be cylindrical in shape, but embodiments of the present disclosure are not limited thereto. For example, the hole wall may have a shape that changes from the top (or first) opening of one or more holes to the bottom (or second) opening. In various embodiments of the present disclosure, the top opening may refer to the opening of the hole 331o facing the second shell 312, and the bottom opening may refer to the opening of the hole 331o facing the first shell 311.

[0405] In embodiments of the present disclosure, the shape of the hole wall can narrow from the top opening to the bottom opening or from the bottom opening to the top opening. In various embodiments of the present disclosure, the size or area of ​​the top opening and the bottom opening can be different from each other, but can also be the same. When different, the top opening can be smaller than the bottom opening, or the bottom opening can be smaller than the top opening.

[0406] In various embodiments of the present disclosure, the shape (or width or diameter) of the hole wall can be widest at the top opening and the bottom opening and gradually become smaller towards the middle of the hole 331o, or can be widest in the middle and gradually become smaller towards the top opening and the bottom opening. The change in the width of the hole wall does not have to be gradual, and there can be one or more steps or curves in the hole wall within the hole 331o. In various embodiments of the present disclosure, the cross-sectional shape of the hole wall can be a triangular wave or a curved wave, a concave shape or a convex shape or various combinations thereof, but is not limited thereto.

Therefore, the sound generated based on the vibration (or driving) of each of the vibration devices 333 and 335 at the rear surface of the vibration member 331 or the second space 313b of the housing 310 can be output to the first space 313a through the at least one or more holes 331o, and can be output (or radiated) through the opening 310o of the first housing 311 and the hollow portion 501 of the coupling portion 500, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range. According to an embodiment of the present disclosure, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal range (e.g., 400 Hz or lower) can be further enhanced.

[0410] Reference Figure 31 In the sound device according to another embodiment of the present disclosure, the housing 310 may include a first housing 311. For example, in the above reference Figures 1 to 26 In the depicted housing 310 , the second housing 312 may be removed (or omitted), and thus, the housing 310 may be configured with only the first housing 311 .

[0411] The housing 310 or the first housing 311 may be connected to the sound generating module 330, with the internal space 313 being between the housing 310 or the first housing 311 and the sound generating module 330. The housing 310 or the first housing 311 may be connected to a rear peripheral portion of the vibration member 331, with the internal space 313 being between the housing 310 or the first housing 311 and the rear peripheral portion of the vibration member 331.

[0412] According to another embodiment of the present disclosure, the vibration member 331 may be configured to cover the inner space 313 of the first housing 311.

[0474] The first adhesive layer 1317 and the second adhesive layer 1319 may be disposed between the first cover member 1313 and the second cover member 1315 to surround the vibration generating part 1311. For example, one or more of the first adhesive layer 1317 and the second adhesive layer 1319 may be disposed to partially or completely surround the vibration generating part 1311.

[0475] Either one of the first cover member 1313 and the second cover member 1315 may be Figures 3 to 32 Adhesive members 332 and 334 are shown connected or coupled to vibration member 331 .

[0476] The vibration generator 1310 according to an embodiment of the present disclosure may further include a signal supply member 1320 .

[0477] The signal supply member 1320 may be configured to supply the 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.

[0478] A portion of the signal supply member 1320 can be accommodated (or inserted) between the first cover member 1313 and the second cover member 1315. The end portion (or distal portion or one side) of the signal supply member 1320 can be set or inserted (or accommodated) between an edge portion (or a peripheral portion) of the first cover member 1313 and an edge portion (or a 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 can accommodate or vertically (or up and down) cover the end portion (or distal portion or one side) of the signal supply member 1320. Therefore, the signal supply member 1320 can be integrated (or configured) as a whole with the vibration generating unit 1311. Therefore, the sound generating module 330 or the vibration devices 333 and 335 can be implemented (or configured) as a membrane type integrated with the signal supply member 1320. For example, the signal supply member 1320 can be configured as a part (or a component) of the vibration generating unit 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.

[0479] 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.

[0480] 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 a first direction X and may extend long along a second direction Y intersecting the first direction X.

[0481] 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 or electrically isolated 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 conductive layer) formed or deposited at the first surface of the base member 1321.

[0482] End portions (or distal end 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.

[0483] The end portion (or distal portion or one side) of the first signal line 1323a can be electrically connected to the first electrode portion 1311b of the vibration generating unit 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 unit 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 can be electrically connected and directly connected to at least a portion of the first electrode portion 1311b of the vibration generating unit 1311. For example, the end portion (or distal portion or one side) of the first signal line 1323a can be electrically connected to or directly contact the first electrode portion 1311b of the vibration generating unit 1311. For example, the end portion of the first signal line 1323a can 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 vibration driver) to the first electrode portion 1311 b of the vibration generating portion 1311 .

[0484] 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 via a conductive double-sided tape. Therefore, the second signal line 1323b can be configured to transmit the second drive signal supplied from the drive circuit portion (or vibration driver) to the second electrode portion 1311c of the vibration generating unit 1311.

[0485] The signal supply member 1320 according to an embodiment of the present disclosure may further include an insulating layer 1325 .

[0486] An insulating layer 1325 may be provided at the first surface of the base member 1321 to cover each of the first and second signal lines 1323 a and 1323 b except for an end portion (or one side) of the signal supply member 1320 .

[0487] 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. Thus, 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 portion 1311 and the first cover member 1313, and thus, contact defects between the vibration generator 1310 and the signal supply member 1320 caused by movement of the signal supply member 1320 can be prevented.

[0488] In the signal supply member 1320 according to an embodiment of the present disclosure, each of the end portion (or side) of the base member 1321 and the end portion (or 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 side) 1325a of the base member 1321 and the end portion (or side) 1325a of the insulating layer 1325, respectively. For example, each of the end portion (or side) 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 portions (or distal portions or sides) of each of the first signal line 1323a and the second signal line 1323b can be bent individually or independently.

[0489] 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 in direct contact with 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 in direct contact with the second electrode portion 1311c of the vibration generating portion 1311.

[0490] 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 provided 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 portion 1311. Therefore, the vibration generating portion 1311 and the signal supply member 1320 may be configured as one portion (or one component), and thus, a single material effect may be obtained.

[0491] 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, there may be no need for a soldering process for electrical connection between the vibration generator 1310 and the signal supply member 1320. Therefore, the manufacturing process and structure of the vibration devices 333 and 335 may be simplified, and the risks associated with the soldering process may be reduced.
