[0025] Reference will now be made in detail to the embodiments of the present specification, examples of which may be illustrated in the accompanying drawings. In the following description, if a detailed description of a well-known function or configuration would unnecessarily obscure the gist of the present specification, the detailed description may be omitted for the sake of brevity. The progression of steps and / or operations described is exemplary, but the order of steps and / or operations is not limited to that described herein and may be modified, except that steps and / or operations necessarily occur in a particular order.

[0026] Unless otherwise specified, the same reference numerals may generally refer to similar components even if they are illustrated in different drawings. In one or more embodiments, the same components (or components having the same name) in different drawings may have the same or substantially the same functions and characteristics, unless otherwise specified. The names of the respective components used in the following description are selected for convenience and may differ from the actual products.

[0027] The advantages and features of the present specification, and the method of achieving them, will become clear by referring to the following detailed description of the embodiment together with the accompanying drawings. However, the present specification is not limited to the embodiment disclosed below, and may be realized in various different forms, and the embodiment is merely provided to complete the disclosure of the specification and to fully inform those skilled in the art of the invention to which the specification pertains.

[0028] In order to explain the embodiments of the present specification, the shapes, sizes, areas, ratios, angles, numbers, etc. shown in the drawings are merely illustrative and are not intended to limit the present specification to the matters shown in the drawings. The reference numbers for components in each drawing may refer to similar components, although the same components may be shown in other drawings, unless otherwise specified.

[0029] When "comprising," "having," "consisting," "comprising," "formed," and the like are used herein, other parts can be added unless "only" or "only" is used. The terms used herein are used merely to describe certain embodiments and are not intended to limit the scope of the present disclosure. The terms used herein are used merely to describe exemplary embodiments and are not intended to limit the scope of the present disclosure.

[0030] Terms expressing elements in the singular include the plural unless expressly stated otherwise. An "embodiment" may be an illustrative example. Any implementation described in this specification as an "embodiment" or "example" should not necessarily be construed as preferred or advantageous over other implementations.

[0031] In one or more embodiments, components, features, or corresponding information (e.g., levels, ranges, dimensions, sizes, etc.) may be interpreted as including an error or tolerance range even if an explicit description of these error or tolerance ranges is not provided. The error or tolerance range may be caused by various factors (e.g., process factors, internal or external impacts, noise, etc.).

[0032] If the description is about a location relationship, when the location relationship between two parts is described using words such as "on or over," "on top," "under or below," "at the bottom," "near," "adjacent to," "beside," or "next to," one or more other parts may be located between the two parts, unless "just," "immediately(ly)," "close(ly)," or "direct(ly)" is used. For example, when structures are described as being located "above or over," "on top," "under or below," "on bottom," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures touch each other and have a third structure disposed between them. For example, when structures are described as being located "above or over," "on top," "under or below," "on bottom," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures touch each other and have a third structure disposed between them. Additionally, terms such as "front", "back", "back", "left", "right", "top", "bottom", "downward", "upward", "top", "bottom", "column", "row", "vertical", "horizontal", etc. refer to any frame of reference.

[0033] When describing a temporal relationship, for example when a temporal sequence is described using "after," "subsequent," "next," "before or preceding or prior to," etc., consecutive or non-consecutive cases may be included since "just," "immediately," or "directly" are not used.

[0034] Although the terms "first", "second", etc. are used to describe various components, these components are not limited by these terms. These terms are merely used to distinguish one component from another. Thus, the first component referred to below may be the second component within the technical spirit of the present invention. Furthermore, the first element, the second element, etc. may be arbitrarily named according to the convenience of a person skilled in the art without departing from the scope of this specification. Terms such as "first", "second", etc. may be used to distinguish components from each other, but the function or structure of the component is not limited by the ordinal number before the component or the name of the component.

[0035] In describing components of this specification, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are used to distinguish the components from other components, and are not used to define the nature, basis, order, or number of the components.

[0036] When a component or layer is described as being "connected," "bonded," or "coupled" to another component, it should be understood that the component may be directly connected or coupled to the other component, but that other components or layers may also be "disposed" or "interposed" between each component that may be indirectly connected or coupled unless specifically and explicitly stated.

[0037] When a component or layer is described as being "in contact with" or "overlapping" another component or layer, the component may be in direct contact with or overlaid on the other component or layer, but it should be understood that one or more other components or layers may be "disposed" or "interposed" between each component or layer that may be in indirect contact or overlaid unless otherwise expressly described. For example, for purposes of this specification, terms such as "overlap" and "overlapping" should be understood as "overlapping, electrically and / or physically connected" by, for example, surface-to-surface connection, and "overlapping, electrically and / or physically connected" by, for example, surface-to-surface connection.

[0038] The term "at least one" should be understood to include all possible combinations of one or more of the associated items. For example, the meaning of "at least one of the first, second, and third items" may include only any combination of the first, second, and third items, and not just combinations of items presented from two or more of the first, second, or third items.

[0039] The phrase "first component", "second component" and / or "third component" should be understood as one of the first, second and third components or any or all combinations of the first, second and third components. For example, A, B and / or C can be considered as A only, B only, C only, any or some combination of A, B and C, or all of A, B and C. Furthermore, the phrase "component A / component B" should be understood as component A and / or component B.

[0040] In one or more embodiments, the terms "between" and "in" may be used interchangeably for convenience only, unless otherwise noted. For example, the phrase "between multiple components" may also be understood as "among multiple components." In other embodiments, the phrase "among multiple components" may also be understood as "between multiple components." In one or more embodiments, the number of components may be two. In one or more embodiments, the number of components may be more than two.

[0041] In one or more embodiments, the term "different from" may be understood to mean that any element is different from the other element.

[0042] In one or more embodiments, the terms "one or more of" and "one or more of" may be used interchangeably for convenience only, unless otherwise specified. For example, the term "one or more of" can also be understood as "one or more of." For example, the term "one or more of" can also be understood as "one or more of."

[0043] The features of the various embodiments herein may be combined or combined with one another in part or in whole, and may be technically interlocked and driven in various ways, and each embodiment may be implemented independently of the other, or may be implemented together in a related relationship. In one or more embodiments, the components of each device according to the various embodiments herein may be operably coupled or configured.

[0044] The "X-axis direction," "Y-axis direction," and "Z-axis direction" should not be construed as geometric relationships that are solely perpendicular to each other, but may have a broader directionality within the range in which the elements of this specification can function.

[0045] The terms used in this specification (including technical and scientific terms) may have the same meaning as that understood by a person having ordinary knowledge in the technical field to which this specification belongs. Furthermore, terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant technology, and should not be interpreted as idealized or overly formal unless otherwise specified.

[0046] Hereinafter, the embodiments of the present specification will be described in detail with reference to the accompanying drawings. Furthermore, for convenience of explanation, the scales, dimensions, sizes and thicknesses of the components shown in the drawings may have different scales, dimensions, sizes and thicknesses from the actual scales, dimensions, sizes and thicknesses, and therefore are not limited to the scales, dimensions, sizes and thicknesses shown in the drawings.

A space is provided between the acoustic device 30 and the enclosure, and sound (or sound pressure) can be output in response to vibration of the vehicle interior material 130 caused by air between the acoustic device 30 and the enclosure. However, there is a problem that low-frequency sound is not output, and the number of peaks and dips generated in the reproduction frequency band of the sound (or sound pressure) generated in response to the vibration of the vehicle interior material 130 increases, and the maximum sound pressure and the minimum sound pressure generated in the reproduction frequency band of the sound (or sound pressure) generated in response to the vibration of the vehicle interior material 130 increase, resulting in a decrease in the flatness of the sound pressure. A peak is a phenomenon in which sound pressure jumps at a specific frequency, and a dip is a phenomenon in which sound generation at a specific frequency is suppressed and low sound pressure is generated. The flatness of the sound pressure may be the difference between the maximum sound pressure and the minimum sound pressure.

[0108] According to embodiments herein, the second enclosure 312 may be configured to have an inverse shape to the first enclosure 311. For example, the first enclosure 311 and the second enclosure 312 may be configured to have symmetrical shapes or structures across the sound generating module 330.

[0109] Each of the first vibrating device 333 and the second vibrating device 335 vibrates the vibrating member 331 to generate sound (or sound pressure or sound waves) in the internal space 313 of the enclosure 310, the enclosure 310 vibrates due to the sound (or sound pressure or sound waves) in the internal space 313 of the enclosure 310, and the vehicle interior material 130 can generate (or output) sound by vibrating due to the vibration of the enclosure 310. For example, the vehicle interior material 130 can vibrate due to the vibration of the first enclosure 311 caused by the sound (or sound pressure or sound waves) generated in the internal space 313 of the enclosure 310 to generate (or output) sound.

[0110] According to embodiments of the present disclosure, the interior space 313 of the enclosure 310 may include a first space 313a and a second space 313b.

[0111] The vibration member 331 may be disposed in the interior space 313 of the enclosure 310. The vibration member 331 may be disposed in the interior space 313 of the enclosure 310 and coupled to a vibration device. For example, the vibration member 331 may be disposed in the interior space 313 of the enclosure 310 and coupled to one or more of the first vibration device 333 and the second vibration device 335. For example, the first vibration device 333 and the second vibration device 335 may be disposed on either side of the vibration member 331.

[0112] The vibration member 331 may be disposed or configured between the first enclosure 311 and the second enclosure 312 of the enclosure 310. The vibration member 331 may be configured to separate the internal space 313 of the enclosure 310 into a first space 313a and a second space 313b. For example, the internal space 313 of the enclosure 310 may be separated into the first space 313a and the second space 313b by the vibration member 331. For example, the first space 313a of the internal space 313 may be provided between the first enclosure 311 of the enclosure 310 and the vibration member 331 and may be covered by the vibration member 331. The second space 313b of the internal space 313 may be provided between the second enclosure 312 of the enclosure 310 and the vibration member 331 and may be covered by the vibration member 331.

[0113] According to an embodiment of the present specification, the first vibration device 333 and the second vibration device 335 may be located in different spaces in the interior space 313 of the enclosure 310. For example, the first vibration device 333 may be located in the first space 313a. For example, the second vibration device 335 may be located in the second space 313b.

[0114] The first space 313a can be between the sound generating module 330 and the first enclosure 311. For example, the first space 313a can be between a first surface of the sound generating module 330 and the first enclosure 311. The first space 313a can be between the first vibration device 333 and the first enclosure 311. The second space 313b can be between the sound generating module 330 and the second enclosure 312. For example, the second space 313b can be between a second surface different (or opposite) from the first surface of the sound generating module 330 and the second enclosure 312. The second space 313b can be between the second vibration device 335 and the second enclosure 312. For example, the internal space 313 can be a gap space, an air gap, a vibration space, an acoustic space, an acoustic pipe, or a sealed space, and the embodiments herein are not limited thereto.

[0115] The sound generating module 330 can generate sound pressure (or sound or sound waves) in the internal space 313 of the enclosure 310 to vibrate the enclosure 310, and the vibration of the enclosure 310 can vibrate the vehicle interior material 130. For example, the sound generating module 330 can be configured to vibrate the first enclosure 311 of the enclosure 310 to vibrate the vehicle interior material 130. For example, the sound generating module 330 can generate sound pressure (or sound or sound waves) in the internal space 313 of the enclosure 310 to vibrate the first enclosure 311, and the vibration of the first enclosure 311 can vibrate the vehicle interior material 130.

[0116] According to embodiments herein, the first enclosure 311 may include an opening 310o.

[0117] The opening 310o may be configured to penetrate (or vertically penetrate) the first enclosure 311 along the thickness direction (Z) (or vertical direction) of the enclosure 310. The opening 310o may be connected to the internal space 313. The opening 310o may be connected to the first space 313a. For example, the opening 310o may be configured to reduce the air pressure in the internal space 313 of the enclosure 310. For example, the opening 310o may be configured to reduce the air pressure in the first space 313a of the first enclosure 311, or in the first space 313a provided between the vibrating member 331 and the first enclosure 311. This allows the range of the bass band to be expanded, thereby improving the acoustic characteristics of the bass band. For example, as the pressure (or air pressure) in the first space 313a decreases through the opening 310o, the displacement (or bending force) of the first vibrating device 333 disposed between the vibrating member 331 and the first enclosure 311 may be increased, thereby expanding the range of the low-frequency band and improving the acoustic characteristics and / or sound pressure characteristics of the low-frequency band. Therefore, the sound (or sound pressure) in the low-frequency band generated by the vibration of the first vibrating device 333 and / or the second vibrating device 335 may be improved.

[0118] According to an embodiment of the present specification, the opening 310o may be arranged to correspond to a central portion of the sound generating module 330. For example, the opening 310o may be arranged to correspond to a central portion of the vibration devices 333, 335. For example, the opening 310o may be arranged to correspond to a central portion of the first vibration device 333 and the second vibration device 335. For example, the opening 310o may be arranged to correspond to a central portion of each of the first vibration device 333 and the second vibration device 335. For example, the interior space 313 of the enclosure 310 may include a space coupled to the opening 310o. For example, the interior space 313 of the enclosure 310 may include a first space 313a coupled to the opening 310o.

[0119] According to an embodiment of the present specification, the opening 310o may be smaller than the size of the first vibrating device 333. For example, the opening 310o may be smaller than the size of the first vibrating device 333 disposed on the vibrating member 331. For example, the opening 310o may include a line shape having a size (or length) smaller than the size of the first vibrating device 333 disposed on the vibrating member 331. For example, the opening 310o may be a hole, a slot, or a slit, and the embodiment of the present specification is not limited thereto. For example, the opening 310o may be an acoustic emission portion, an acoustic emission port, an acoustic output portion, an acoustic output port, an acoustic output hole, or a vent hole, and the embodiment of the present specification is not limited thereto.

[0120] The opening 310o may be a space through which sound waves generated by the vibration of the sound generating module 330 are propagated (or transmitted) to the interior space of the vehicle. For example, the vibration of the sound generating module 330 may be transmitted to the interior space of the vehicle through the opening 310o. For example, sound waves (or sound) caused by the vibration of the sound generating module 330 may be transmitted (or output or emitted) to the interior space of the vehicle through the opening 310o. This can increase the vibration amplitude (or displacement amplitude) of the vibrating member 331 accompanying the vibration of the sound generating module 330, thereby improving the acoustic characteristics and / or sound pressure characteristics generated accompanying the vibration of the vibrating member 331.

[0121] The first enclosure 311 may be disposed closer to the vehicle interior material 130 than the second enclosure 312. For example, the first enclosure 311 including the opening 310o may be disposed closer to the vehicle interior material 130 than the second enclosure 312. This allows sound generated by vibration of one or more of the first vibrating device 333 and the second vibrating device 225 to be output to the interior space of the vehicle, so that sound including a low-frequency band can be output to the interior space of the vehicle.

[0122] The first enclosure 311 may include an inclined surface 311s and an inner side surface 311i. The first inclined surface 311s may be configured to be inclined between the inner side surface 311i of the first enclosure 311 and the opening 310o. The inclined surface 311s may be configured to guide the sound generated by the vibration of the sound generating module 330 to the interior space of the vehicle. This allows the sound generated by the vibration of the sound generating module 330 to be output to the interior space of the vehicle, and the acoustic characteristics and / or sound pressure characteristics of the sound including the low-frequency band may be further improved. For example, the inclined surface 311s may be a guide surface or an acoustic guide surface, and the embodiments of the present specification are not limited thereto.

[0123] The vibration member 331 may be arranged or configured to be spaced apart from the opening 310o.

For example, the vibration member 331 may be arranged in the interior space 313 and supported by at least one of the first enclosure 311 and the second enclosure 312. For example, the vibration member 331 may be arranged to cover the interior space 313 and supported by at least one of the first enclosure 311 and the second enclosure 312. For example, the vibration member 331 may be arranged to cover the interior space 313 of the enclosure 310. For example, the vibration member 331 may be supported by the first enclosure 311 and the second enclosure 312.

[0124] According to an embodiment of the present specification, the first enclosure 311 of the enclosure 310 may be disposed or configured on a first surface (or back surface) of the vibration member 331. The first enclosure 311 of the enclosure 310 may be coupled (or connected) to the first surface of the vibration member 331.

[0125] According to an embodiment of the present specification, the second enclosure 312 may be disposed or configured on a second side (or back side) different from (or opposite to) the first side of the vibration member 331. The second enclosure 312 may be configured to support an edge portion of the second side of the vibration member 331. The second enclosure 312 of the enclosure 310 may be coupled (or connected) to the second side of the vibration member 331. For example, the second enclosure 312 may be coupled (or connected) to an edge portion of the second side of the vibration member 331. For example, the second enclosure 312 may be configured to cover the second side of the sound-generating module 330. For example, the second enclosure 312 may be configured to surround the second side of the sound-generating module 330.

[0126] The acoustic device 30 according to the embodiments of the present specification may further include a coupling member 320. The coupling member 320 may be configured to connect or couple the vibration member 331 and the enclosure 310 to each other.

The coupling member 320 may include a first coupling member 321 and a second coupling member 322.

[0127] The first coupling member 321 can be between the vibration member 331 and the first enclosure 311. The first coupling member 321 can be between an edge portion of the vibration member 331 and an edge portion of the first enclosure 311. For example, the edge portion of the first enclosure 311 can be coupled or connected to a first side of the vibration member 331 by the first coupling member 321. For example, the edge portion of the first enclosure 311 can be coupled or connected to an edge portion of the first side of the vibration member 331 by the first coupling member 321.

[0128] The second coupling member 322 can be between the vibration member 331 and the second enclosure 312. The second coupling member 322 can be between an edge portion of the vibration member 331 and an edge portion of the second enclosure 312.

[0131] The acoustic device 30 according to an embodiment of the present specification includes the sound generating module 330 having a bimorph structure, and therefore the acoustic characteristics and / or sound pressure characteristics of the sound including the low frequency band can be improved. Since the acoustic device 30 according to an embodiment of the present specification includes the enclosure 310 having the opening 310o, the sound range of the low frequency band can be expanded as the air pressure in the internal space 313 of the enclosure 310 decreases, and therefore the acoustic characteristics and / or sound pressure characteristics of the low frequency band can be improved.

[0132] In various embodiments herein, the multiple acoustic devices 30 may be provided and arranged in various configurations. For example, two or more of the multiple acoustic devices may be stacked together or arranged side by side with each other.

[0150] The soft member 360 may be made of a material different from that of the connecting member 350. The elasticity (or Young's modulus) of the soft member 360 may be different from that of the connecting member 350. For example, the soft member 360 may be made of a material having low elasticity. The soft member 360 may be made of a soft material. For example, the soft member 360 may be ethylene propylene rubber or urethane rubber, and the embodiment of the present specification is not limited thereto. The ethylene propylene rubber may be ethylene propylene diene monomer (EPDM), and may be made of EPDM having low elasticity by changing the foaming rate of EPDM, and the embodiment of the present specification is not limited thereto.

For example, the hole 310o may be different from the hole 360o. In various embodiments herein, the opening 360o of the soft member 360 may be larger or wider than the opening 310o of the first enclosure. The larger the size of the hole 360o, the better the sound will be emitted from the enclosure 310, and the smaller the hole 360o, the more the amount of sound emitted may be adjusted. In various embodiments herein, the size of at least one of the holes 310o, 360o may be freely changed to become larger or smaller in size in real time, such as by using a cover that can be closed or opened, or the size of each of the holes 310o, 360o may be changed to modulate the sound emitted from the enclosure 310. Also, holes 310o, 360o do not have to be aligned or overlapping, but can be partially overlapping or offset from one another. If offset from one another, there can be a communicating hole extending from hole 310o to hole 360o to allow sound to escape from enclosure 310.

[0153] In various embodiments of the present specification, the shape of the hole 310o and the shape of the hole 360o can correspond as described below, and the embodiments of the present specification are not limited thereto. For example, the shapes of the holes 310o, 360o can be different from each other in various embodiments. Also, the shapes of the holes 310o, 360o can be changed in real time using a cover such as an iris diaphragm or a rotating diaphragm.

[0154] According to one embodiment of the present specification, the soft member 360 may be protected by a release film (or a protective film) 361.

[0312] As shown in FIG. 25B, the connecting member 380 may have an initial thickness (T1') before compression (or contraction), and may be compressed (or contracted) to a deformed thickness (or compressed thickness) (T1) shown in FIG. 25A by the pressure applied from the enclosure 310 by the coupling (or connection) of the coupling portion 500 and the enclosure 310. For example, when the acoustic device 30 is coupled to the vehicle interior material 130 by the coupling portion 500, or when assembly and / or reworking is completed, the thickness of the connecting member 380 may be compressed from the initial thickness (T1') to the compressed thickness (T1), so that the vibration of the enclosure 310 may be efficiently transmitted to the vehicle interior material 130. For example, when the acoustic device 30 is separated (or detached) from the vehicle interior material 130 by the separation of the coupling portion 500, the connecting member 380 may be restored from the deformed thickness (T1) to the initial thickness (T1') by the elastic restoring force.

[0313] 25A and 25B, the coupling unit 500 may be connected or coupled to the acoustic 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 enclosure 310 (in the direction of the arrows). For example, the coupling unit 500 may be connected or coupled to the opening 310o of the first enclosure 311 through the second hole 135 of the vehicle interior material 130 and the hole 380o of the connecting member 380 in the interior space of the vehicle. According to one embodiment of the present specification, the coupling unit 500 may be connected or coupled to the acoustic device 30 or the enclosure 310 through the hole 135 of the vehicle interior material 130 (in the direction of the arrows) in the interior space of the vehicle. For example, the connecting portion 500 may be accommodated or inserted into the hole 380o of the connecting member 380 and the opening 310o of the first enclosure 311 through the hole 135 of the vehicle interior material 130 in the interior space of the vehicle. For example, the hook member 504 of the coupling portion 500 may be coupled or connected to the opening 310o of the first enclosure 311. For example, the hook member 504 of the coupling portion 500 may be inserted (or accommodated) into the opening 310o of the first enclosure 311 and coupled or connected to the home portion 311g of the first enclosure 311 by a hook coupling manner.

For example, the first enclosure 311 may be coupled or connected to at least one or more curved portions 136 of the vehicle interior material 130 by the coupling member 380.

[0317] Referring to FIG. 25C, the thickness (T1) of the connecting member 380 may be different from the thickness of at least one of the first connecting member 321 and the second connecting member 322.

Thereby, the connecting member 380 can be in surface contact with the vehicle interior material 130 including at least one or more curved surface portions 136 by the connecting force between the connecting portion 500 and the first enclosure 311.

[0318] According to the embodiment of the present specification, the sound generated by the vibration of the sound generating module 330 may be outputted to the interior space of the vehicle through the opening 310o, the hole 380o, and the second hole 135.

This may further improve the acoustic characteristics and / or sound pressure characteristics in the low frequency range, and the connecting member 380 made of a rubber material may facilitate the attachment or detachment process of the sound generating module 330 attached to the vehicle interior material 130.

[0320] Fig. 26 is a diagram showing an acoustic device according to another embodiment of the present specification. Figs. 27 to 30 are internal views of an acoustic device according to another embodiment of the present specification. Figs. 26 to 30 show an acoustic device 30 described with reference to Figs. 1 to 25, further configured with at least one hole. In the following description, the at least one hole will be described in detail, and the remaining configuration is substantially the same as the contents described with reference to Figs. 1 to 25C, so the same reference numbers will be used therefor, and duplicated descriptions may be omitted or simplified.

[0321] Referring to FIG. 26, an audio device 30 according to another embodiment of the present disclosure may further include at least one hole 331o.

[0322] At least one or more holes 331o may be configured in the vibration member 331. At least one or more holes 331o may be formed to penetrate the vibration member 331. For example, at least one or more holes 331o may be configured to penetrate the vibration member 331 along a thickness direction (Z) of the vibration member 331. For example, at least one or more holes 331o may be formed to penetrate vertically along the thickness direction (Z) of the vibration member 331.

[0323] The sound generating module 330 according to the embodiment of the present specification may include a vibration member 331 including at least one hole 331 o and vibration devices 333 and 335 configured on the vibration member 331 .

[0324] At least one or more holes 331o may be configured to adjust the flow of air in the internal space 313 of the enclosure 310. For example, the at least one or more holes 331o may adjust the flow of air in the internal space 313 of the enclosure 310, which is spatially separated by the vibration member 331. For example, the at least one or more holes 331o may be configured to adjust the flow of air between the first space 313a and the second space 313b, which are spatially separated by the vibration member 331, in the internal space 313 of the enclosure 310. For example, the at least one or more holes 331o may be a first hole, a vent hole, a ventilation hole, a duct hole, a first connection hole, a first communication hole, or a first space connection part, and the embodiments of the present specification are not limited thereto.

[0325] At least one hole 331o according to the embodiment of the present disclosure may be configured in a circular, elliptical, or polygonal shape such as a square, but the embodiment of the present disclosure is not limited thereto.

[0326] At least one or more holes 331o may be configured to reduce the air pressure in the internal space 313 of the enclosure 310. For example, at least one or more holes 331o may be configured to connect the first space 313a and the second space 313b, which are spatially separated by the vibrating member 331, in the internal space 313 of the enclosure 310. For example, the first space 313a and the second space 313b of the internal space 313 inside the enclosure 310 may be connected (or communicated) with each other through at least one or more holes 331o. For example, at least one or more holes 331o may be configured to reduce the air pressure in the first space 313a of the first enclosure 311, or the first space 313a provided between the vibrating member 331 and the first enclosure 311. This can expand the band (reproduction band) of the low-frequency band, thereby improving the acoustic characteristics and / or sound pressure characteristics of the low-frequency band. Furthermore, the at least one hole 331o in the vibrating member 331 allows the sound generating module 330 to vibrate more stably, so that the acoustic characteristics and / or sound pressure characteristics can be further improved.

[0327] According to an embodiment of the present specification, the internal space 313 may be between the first surface of the sound generating module 330 and the first enclosure 311, and may be connected to the opening 310o. The internal spaces 313 may be connected (or communicated) with each other via at least one or more holes 331o. The enclosure 311 may include a second space 313b between a second surface opposite to the first surface of the sound generating module 330 and the second enclosure 312. The internal space 313 and the second space 313b may be connected (or communicated) with each other via at least one or more holes 331o.

[0328] According to an embodiment of the present specification, at least one or more holes 331o may be arranged adjacent to the vibration devices 333, 335. For example, at least one or more holes 331o may be arranged around the vibration devices 333, 335. For example, at least one or more holes 331o may be arranged adjacent to the side of the vibration devices 333, 335. For example, the distance between the at least one or more holes 331o and the vibration devices 333, 335 may be shorter than the distance between the at least one or more holes 331o and the side wall (or side) of the enclosure 310. For example, when the at least one or more holes 331o are located away from the vibration devices 333, 335, the acoustic characteristics and / or sound pressure characteristics of the low frequency band may be reduced.

[0329] According to an embodiment of the present specification, at least one or more holes 331o may be configured in the vibration member 331 adjacent to the vibration devices 333, 335 with the vibration devices 333, 335 sandwiched therebetween. For example, the vibration member 331 may include a first peripheral region adjacent to a first side of the vibration devices 333, 335 and a second peripheral region adjacent to a second side opposite to the first side of the vibration devices 333, 335. For example, based on the first direction (X), the vibration member 331 may include a first peripheral region, a vibration region, and a second peripheral region. For example, in the vibration member 331, each of the first and second peripheral regions may be a hole region or a region where the vibration devices 333, 335 are not arranged, and the vibration region may be a region where the vibration devices 333, 335 are arranged. For example, the vibration member 331 may be configured in the first peripheral region and the second peripheral region so that at least one or more holes 331o have a symmetrical structure (or a bilaterally symmetrical structure) or an asymmetrical structure (or a bilaterally asymmetrical structure) with respect to the vibration devices 333, 335, respectively.

[0330] According to an embodiment of the present specification, the vibration device 333, 335 may 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 side of the vibration device 333, 335 may be expressed as a ratio to the length of the short side of the vibration device 333, 335. According to one embodiment of the present specification, the distance between the at least one or more holes 331o and the vibration device 333, 335 may be 60% or less of the length of the short side of the vibration device 333, 335.

[0331] 26 and 27, the at least one or more holes 331o may be arranged closer to the vibration devices 333, 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, the at least one or more holes 331o may be arranged closer to the vibration devices 333, 335 than the first coupling member 321 and the second coupling member 322. This can improve the acoustic characteristics and / or sound pressure characteristics in the low frequency range. The acoustic output characteristics according to the distance between the vibration devices 333, 335 and the at least one or more holes 331o will be described later with reference to FIGS. 62A and 62B.

[0332] According to an embodiment of the present specification, at least one or more holes 331o may not overlap with the opening 310o. For example, at least one or more holes 331o may be arranged apart from the opening 310o. As a result, sound generated in the second space 313b by vibration (or driving) of the vibration devices 333 and 335 may be output to the first space 313a through at least one or more holes 331o, so that the acoustic characteristics and / or sound pressure characteristics of the low frequency range may be improved.

[0333] 26 and 28, the size of the at least one or more holes 331o may be different from the size of the at least one or more holes 331o shown in FIG. 27. The larger the size of the at least one or more holes 331o, the more the acoustic characteristics and / or sound pressure characteristics of the low frequency band may be increased. For example, the distance between the at least one or more holes 331o and the vibration device 333, 335 may be shorter than the distance between the at least one or more holes 331o and the side wall (or side surface) of the enclosure 310. For example, the larger the size of the at least one or more holes 331o, the more the sound pressure characteristics of the low frequency band, for example, below 400 Hz, may be further improved. The acoustic output characteristics according to the size of the at least one or more holes 331o will be described later in FIG. 61A, FIG. 61B, and FIG. 63.

[0334] 26 and 29, the at least one or more holes 331o may be configured with two holes 331o. For example, the acoustic device 30 according to another embodiment of the present specification 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 distances 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 along the first direction (X) to be adjacent to the vibration devices 333 and 335. For example, the distances between each of the two holes 331o and the vibration devices 333 and 335 may be the same. For example, the two holes 331o may be configured adjacent to the vibration devices 333 and 335. For example, two holes 331o may be configured in parallel along the second direction (Y) to be adjacent to the vibration devices 333, 335.

[0335] Each of the two holes 331o according to the embodiment of the present specification may be configured in a polygonal shape such as a circle, an ellipse, or a rectangle, and the embodiment of the present specification is not limited thereto.

[0336] 26 and 30, at least one or more holes 331o may be configured in a rectangular shape. For example, two holes 331o may be configured adjacent to the vibration devices 333 and 335. The acoustic output characteristics according to the shape of at least one or more holes 331o will be described later in FIG. 64.

[0337] According to the embodiment of the present specification, the at least one hole 331o can output the sound (or rear sound) generated by the vibration of the vibration devices 333 and 335 and emitted to the rear (or rear) of the vibration member 331 through the opening 310o of the first enclosure 311. As a result, the sound generated in the rear of the vibration member 331 or the second space 313b of the enclosure 310 by the vibration (or drive) of the vibration devices 333 and 335 is output to the first space 313a through the at least one hole 331o, and output (or radiate) through the opening 310o of the first enclosure 311 and the hollow portion 501 of the coupling portion 500, so that the acoustic characteristics and / or sound pressure characteristics of the low frequency band can be further improved. According to the embodiment of the present specification, the at least one hole 331o in the vibration member 331 can further improve the acoustic characteristics and / or sound pressure characteristics of the low frequency band, for example, at 400 Hz or less.

[0338] Fig. 31 is a diagram showing an acoustic device according to another embodiment of the present specification. Fig. 31 shows an acoustic device 30 described with reference to Figs. 1 to 30 with a modified enclosure. In the following description, the enclosure will be described in detail, and the remaining configuration is substantially the same as that described with reference to Figs. 1 to 30, so the same reference numerals will be used therefor, and duplicated descriptions may be omitted or simplified.

[0339] 31, in an acoustic device 30 according to another embodiment of the present specification, the enclosure 310 may include a first enclosure 311. For example, the enclosure 310 may be configured with only the first enclosure 311, with the second enclosure 312 removed (or omitted) from the enclosure 310 described with reference to FIGS.

[0340] The enclosure 310 or the first enclosure 311 may be connected to the acoustic device 30 across the internal space 313. The enclosure 310 or the first enclosure 311 may be connected to a rear edge portion of the vibration member 331 across the internal space 313.

[0341] According to other embodiments herein, the vibration member 331 may be configured to cover the interior space 313 of the first enclosure 311.

The vibration member 331 may be configured to cover the first space 313a of the first enclosure 311. For example, the vibration member 331 may be configured to cover a portion of the first space 313a of the first enclosure 311.

[0342] When the enclosure 310 is composed of the first enclosure 311, the acoustic characteristics and / or sound pressure characteristics of the acoustic device 30 can be further improved than when the enclosure 310 is composed of the first enclosure 311 and the second enclosure 312. For example, when the enclosure 310 is composed of the first enclosure 311, the acoustic characteristics and / or sound pressure characteristics of the mid-low frequency band, for example, the frequency band of 2 kHz or less, can be further improved, and the sound reproduction band can be further expanded.

The outer surface of the first enclosure 311 may be the surface opposite to the inner surface 311i. For example, the connecting member 380 may be connected to the outer surface of the enclosure 310 or the first enclosure 311.

[0345] According to an embodiment of the present specification, the vibration of the first enclosure 311 may be dissipated by the connecting member 380 when it is transmitted to the vehicle interior material 130. Therefore, the connecting member 380 may be made of a material that can transmit the vibration of the sound generating module 330 and / or the first enclosure 311 to the vehicle interior material 130 without vibration loss. For example, the connecting member 380 may be made of a material that can contract depending on the shape of the vehicle interior material 130.

This may facilitate a process of attaching or mounting the audio device 30 to the vehicle interior material 130, or a process of separating or detaching the audio device 30 from the vehicle interior material 130.

[0349] In other embodiments of this specification, since each of the connecting member 380 and the first coupling member 321 is substantially the same as that described in Figures 25A to 25C, the same symbols are used therefor, and duplicate descriptions thereof may be omitted or simplified.

The acoustic output characteristics according to the thickness (T1) of the connecting member 380 will be described later with reference to FIG. 67.

[0351] According to another embodiment of the present specification, the acoustic device 30 is configured to include a first enclosure 311 and a connecting member 380, thereby further improving the acoustic characteristics and / or sound pressure characteristics of the low-frequency and mid-frequency bands, expanding the sound reproduction band, and facilitating the attachment or detachment process of the sound generating module 330 attached to the vehicle interior material 130.

[0352] According to another embodiment of the present specification, the connecting member 380 between the vehicle interior material 130 and the enclosure 311 is made of a material such as rubber, so that vibrations of the sound generating module 330 and / or the enclosure 310 or the first enclosure 311 can be transmitted to the vehicle interior material 130 without being lost, thereby further improving the acoustic characteristics and / or sound pressure characteristics of the acoustic device 30.

[0355] According to another embodiment of the present specification, the acoustic device 30 may include the first enclosure 311 and at least one or more holes 331o, or may include the first enclosure 311. When the acoustic device 30 is configured to include the first enclosure 311 and at least one or more holes 331o, the acoustic characteristics and / or sound pressure characteristics of the low frequency band and the mid frequency band may be further improved, and the sound reproduction band may be further expanded. When the acoustic device 30 is configured to include the first enclosure 311, the acoustic characteristics and / or sound pressure characteristics of the mid-low frequency band may be further improved, and the sound reproduction band may be further expanded.

[0356] An acoustic device 30 according to another embodiment of the present specification may further include a coupling member 320 or a first coupling member 321. The first coupling member 321 may be between the vibration member 331 and the first enclosure 311.

[0357] According to another embodiment of the present disclosure, the acoustic device 30 may further include a connecting member 380 .

[0358] The connecting member 380 according to other embodiments of the present specification may be configured between the first enclosure 311 and the vehicle interior material 130. For example, the connecting member 380 may be configured of a material different from the first connecting member 321. For example, the connecting member 380 may be configured of a material having a higher elasticity than the first connecting member 321. For example, the connecting member 380 may be configured of a material having a different adhesive strength from that of the first connecting member 321. Since the connecting member 380 is configured of a material having an adhesive strength different from that of the first connecting member 321, in a process of separating or detaching the audio device 30 attached to the vehicle interior material 130 (or reworking), the connecting member 380 may be easily separated or detached (or reworked) from the vehicle interior material 130. This may facilitate a process of attaching or mounting the audio device 30 to the vehicle interior material 130, or a process of separating or detaching the audio device 30 from the vehicle interior material 130.

The second region (A2) may correspond to an edge portion surrounding the central portion of the enclosure 310 or the first enclosure 311. The third region (A3) may be between the first region (A1) and the second region (A2). For example, the first portion of the connecting member 380 may be between the first region (A1) and the second region (A2). For example, the second portion of the connecting member 380 may be in the second region (A2).

[0421] According to an embodiment of the present specification, the first and second portions of the connecting member 380 may have different thicknesses. For example, the connecting member 380 may include a first and second portion having different thicknesses. In the connecting member 380, the thickness (T1) of the first portion may be different from the thickness (T1+T2) of the second portion. For example, in the connecting member 380, the thickness (T1+T2) of the second portion may be thicker than the thickness (T1) of the first portion. For example, the thickness (T1) of the connecting member 380 in the first region (A1) may be different from the thickness (T1+T2) of the connecting member 380 in the second region (A2). At least one of the thicknesses of the connecting member 380 in each of the first region (A1) and the third region (A3) may be different from the thickness (T1+T2) of the connecting member 380 in the second region (A2). For example, the thickness (T1+T2) of the connecting member 380 in the second region (A2) may be greater than the thickness (T1) of the connecting member 380 in the first region (A1).

[0422] According to the embodiment of the present specification, since the second portion of the connecting member 380 has a thickness (T1+T2) greater than that of the first portion, the edge portion of the connecting member 380 can be connected to or contacted with the vehicle interior material 130 without lifting up. This can prevent the edge portion of the connecting member 380 from lifting up from the vehicle interior material 130, and vibrations within the edge portion of the enclosure 310 can be transmitted to the vehicle interior material 130 without loss of vibration (or vibration transmission) at the edge portion of the enclosure 310. The vibrations at the edge portion of the enclosure 310 increase the vibration area of ​​the vehicle interior material 130, so that the acoustic characteristics of the low-frequency range can be further improved or complemented. Therefore, the sound generated by the vibration of the acoustic device 30 can be transmitted to the vehicle interior material 130 without loss, so that the sound of the low-frequency range can be further improved. For example, sound generated by vibration of the acoustic device 30 may be transmitted to the vehicle interior material 130 through the opening 310o and the edge portion of the enclosure 310, thereby increasing the efficiency of the vibration transmitted from the enclosure 310 to the vehicle interior material 130 and further improving the acoustic characteristics and / or sound pressure characteristics in the low-frequency range.

[0423] The connecting member 380 according to an embodiment of the present disclosure may include a first connecting member 381 and a second connecting member 382 .

[0424] The first connecting member 381 can be in a first portion and a second portion. The first connecting member 381 can be connected to the enclosure 310. The first connecting member 381 can be connected (or attached) to the first enclosure 311. The first connecting member 381 can be connected (or attached) to the back surface of the first enclosure 311. The first connecting member 381 can be connected (or attached) to the first to third regions (A1, A2, A3) of the enclosure 310. For example, the first connecting member 381 can be connected (or attached) to the entire back surface of the first enclosure 311.

[0425] According to an embodiment of the present specification, the first connecting member 381 may include an opening hole 380o in the first portion and connected to the internal space 313 of the enclosure 310. For example, the first connecting member 381 may include an opening hole 380o in the first portion and connected to the internal space 313 of the first enclosure 311.

[0426] The second connecting member 382 can be in the second portion. The second connecting member 382 can be connected to a portion of the first connecting member 381. The second connecting member 382 can be on the first connecting member 381 in the second portion. For example, the first portion can include only the first connecting member 381 of the first connecting member 381 and the second connecting member 382. The first connecting member 381 and the second connecting member 382 can be together in the second portion. For example, the second portion can include both the first connecting member 381 and the second connecting member 382. For example, the first connecting member 381 and the second connecting member 382 can be together in the second region (A2).

[0427] The first and second portions of the connecting member 380 may have different widths (or sizes). The width of the first portion of the connecting member 380 may be smaller than the width of the second portion. For example, the width of the connecting member 380 in the first region (A1) and the third region (A3) may be smaller than the width of the connecting member 380 in the second region (A2). Thus, the connecting member 380 may include first and second portions having different sizes (or widths) and thicknesses.

[0428] The second connecting member 382 may be at the edge of the first connecting member 381. The second connecting member 382 may be configured by being laminated to the first connecting member 381 in the second portion. For example, the second connecting member 382 may be configured by being laminated to the first connecting member 381 in the second region (A2). This allows the thickness (T1+T2) of the second portion of the connecting member 380 to be made thicker than the thickness (T1) of the first portion, so that the edge portion of the enclosure 310 can be connected to (or contact) the vehicle interior material 130 without lifting up. For example, the second connecting member 382 may be a cushion member or a pad member, and the embodiments of the present specification are not limited thereto.

[0429] The first connecting member 381 may be substantially the same as the connecting member 380 described in Figures 25A to 25C and 31 to 43. Therefore, since the description of the first connecting member 381 is substantially the same as the contents described in Figures 25A to 25C and 31 to 43, the same reference numerals are used thereto, and duplicate descriptions thereof may be omitted or simplified.

[0430] The second connecting member 382 may include the same material (or material) as the first connecting member 381, and the embodiments of the present specification are not limited thereto. For example, one of the first connecting member 381 and the second connecting member 382 may be made of a material having a relatively high elasticity (or Young's modulus). One of the first connecting member 381 and the second connecting member 382 may be a highly elastic rubber, and the embodiments of the present specification are not limited thereto. One of the first connecting member 381 and the second connecting member 382 may be made of a material having a relatively high elasticity (or Young's modulus) and a relatively high tensile strength. For example, one of the first connecting member 381 and the second connecting member 382 may include a rubber material or may be made of ethylene propylene diene rubber (or ethylene propylene diene M class rubber), ethylene propylene rubber, or urethane rubber. For example, the ethylene propylene rubber may be ethylene propylene diene monomer (EPDM), and the embodiments of the present specification are not limited thereto. For example, the hardness of EPDM may be 40 to 90, and the examples of the present specification are not limited thereto. For example, the tensile strength of EPDM is 50 kg / cm 2 ~200kg / cm 2 For example, the minimum elongation of EPDM may be 200%, and the examples herein are not limited thereto. For example, the service temperature of EPDM may be -30°C to 110°C, and the examples herein are not limited thereto.

[0431] According to embodiments of the present specification, the coupling member 320 may be made of a material different from the connecting member 380. For example, at least one of the first connecting member 381 and the second connecting member 382 may be made of a material having a higher elasticity than the coupling member 320.

[0432] According to embodiments herein, the width of the connecting member 380 in the second portion may be greater than the width of the coupling member 320. For example, the width of the connecting member 380 in the second region (A2) may be greater than the width of the coupling member 320.

[0433] According to an embodiment of the present specification, each of the first connecting member 381 and the second connecting member 382 of the connecting member 380 has a compressive force (or contraction force) and an elastic restoring force, and can be contracted or compressed by the connection between the connecting portion 500 and the first enclosure 311. For example, the first connecting member 381 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a first thickness (T1) compressed by the pressure force of the first enclosure 311. The second connecting member 382 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a second thickness (T2) compressed by the pressure force of the first enclosure 311.

[0434] The first thickness (T1) of the first connecting member 381 may be the same as or different from the second thickness (T2) of the second connecting member 382. The first thickness (T1) of the first connecting member 381 and the second thickness (T2) of the second connecting member 382 may be 0.5 mm or more, and the embodiments of the present specification are not limited thereto. For example, the first thickness (T1) of the first connecting member 381 and the second thickness (T2) of the second connecting member 382 may be 0.5 mm to 3 mm, and the embodiments of the present specification are not limited thereto.

[0435] The acoustic device 30 according to another embodiment of the present specification may further include an air gap (AG) in a region between the enclosure 310 and the vehicle interior material 130. For example, the air gap (AG) may be in a region between the first portion of the connecting member 380 and the vehicle interior material 130, or in a region between the first portion and the second portion of the connecting member 380. For example, the air gap (AG) may be in a third region (A3) between the first region (A1) and the second region (A2) of the enclosure 310. For example, the air gap (AG) may be in a region between the third region (A3) of the enclosure 310 and the vehicle interior material 130. For example, by providing the air gap (AG) in the third area (A3) between the first area (A1) and the second area (A2) of the enclosure 310, it is possible to separate or minimize interference between the vibrations of the first area (A1) and the second area (A2), thereby increasing the vibration force (or vibration amount) transmitted from the second area (A2) of the enclosure 310, for example, the edge portion, to the vehicle interior material 130. This allows the range (reproduction range) of the low-frequency band to be expanded, and therefore the acoustic characteristics and / or sound pressure characteristics of the low-frequency band can be further improved.

[0436] According to an embodiment of the present specification, by configuring the connecting member 380 to include first and second portions having different thicknesses, it is possible to provide an acoustic device 30 having improved acoustic characteristics and / or sound pressure characteristics in the low frequency range. According to an embodiment of the present specification, by configuring the second connecting member 382, ​​it is possible to increase the vibration area (or vibration region) of the roof trim when connecting the acoustic device 30 to the roof trim of a vehicle, thereby further improving the acoustic characteristics and / or sound pressure characteristics in the low frequency range.

[0437] FIG. 44 is a diagram showing a method of connecting the acoustic device shown in FIG. 43 and a connecting portion according to another embodiment of this specification.

[0438] 43 and 44, according to one embodiment of the present specification, the first connecting member 381 of the connecting member 380 may be connected (or attached) to the rear (or first or second part) of the enclosure 310 or the first enclosure 311 such that the hole 380o of the enclosure 310 or the first enclosure 311 overlaps (or is connected) with the opening 310o, and the second connecting member 382 of the connecting member 380 may be connected (or attached) to the edge portion (or second part) of the first connecting member 381. The enclosure 310 or the first enclosure 311 may be disposed on the vehicle interior material 130 such that the opening 310o overlaps (or is connected) with the hole 135 of the vehicle interior material 130. The coupling part 500 may be connected or coupled to the audio device 30 or the enclosure 310 through the hole 135 of the vehicle interior material 130 (in the direction of the arrow) in the interior space of the vehicle. For example, the connecting part 500 may be connected or coupled to the audio device 30 or the enclosure 310 through the second hole 135 of the vehicle interior material 130 and the hole 380o of the first connecting member 381 (in the direction of the arrow) in the interior space of the vehicle. For example, the connecting part 500 may be accommodated or inserted into the second hole 135 of the vehicle interior material 130, the hole 380o of the first connecting member 381, and the opening 310o of the first enclosure 311 in the interior space of the vehicle. For example, the hook member 504 of the coupling part 500 may be coupled or coupled to the opening 310o of the first enclosure 311. For example, the hook member 504 of the coupling part 500 may be inserted (or accommodated) into the opening 310o of the first enclosure 311 and coupled or coupled to the home part 311g of the first enclosure 311 by a hook coupling manner. Therefore, the first enclosure 311 is connected (or in contact) with the vehicle interior material 130 by connection with the connecting portion 500 and by the first connecting member 381 and the second connecting member 382, ​​and can output sound by vibrating the vehicle interior material 130 through the vibration of the vibration device.

[0439] The first connecting member 381 may have an initial thickness (T1') before compression (or contraction), and may be compressed (or contracted) to a deformed thickness (or compressed thickness) (T1) by the pressure applied from the enclosure 310 by the coupling (or connection) of the coupling part 500 and the enclosure 310. For example, when the coupling part 500 is coupled (or connected) to the enclosure 310, the thickness of the first connecting member 381 may be compressed from the initial thickness (T1') to the compressed thickness (T1) by the pressure applied from the enclosure 310, so that the vibration of the first area (A1) in the first enclosure 311 may be efficiently transmitted to the vehicle interior material 130 through the first part of the first connecting member 381. For example, when the acoustic device 30 is separated (or detached) from the vehicle interior material 130 by the separation of the coupling part 500, the first connecting member 381 may be restored from the deformed thickness (T1) to the initial thickness (T1') by the elastic restoring force.

[0440] The second connecting member 382 may have an initial thickness (T2') before compression (or contraction), and may be compressed (or contracted) to a deformed thickness (or compressed thickness) (T2) by the pressure applied from the enclosure 310 when the connecting part 500 and the enclosure 310 are connected (or joined). For example, when the connecting part 500 is connected (or joined) to the enclosure 310, the thickness of the second connecting member 382 may be compressed from the initial thickness (T2') to the compressed thickness (T2) by the pressure applied from the enclosure 310, so that vibrations of the second region (A2) in the first enclosure 311 may be efficiently transmitted to the vehicle interior material 130 via the first connecting member 381 and the second connecting member 382. For example, when the acoustic device 30 is separated (or detached) from the vehicle interior material 130 by separating the coupling portion 500, the second connecting member 382 can be restored from the deformed thickness (T2) to the initial thickness (T2') by the elastic restoring force.

[0441] The vehicle interior material 130 connected (or in contact) with the enclosure 310 or the first enclosure 311 can be deformed to include a bent portion or at least one curved portion by the connection (or coupling) between the coupling portion 500 and the enclosure 310, and thus lifting generated between the edge portion of the enclosure 310 or the first enclosure 311 and the vehicle interior material 130 can be prevented by the second portion of the coupling member 380 having a relatively large thickness. As a result, the vibration at the edge portion of the enclosure 310 or the first enclosure 311 caused by the vibration of the vibration device can be transmitted to the vehicle interior material 130 without loss, so that the efficiency of vibration transmitted from the enclosure 310 to the vehicle interior material 130 can be improved, and the acoustic characteristics and / or sound pressure characteristics in the low frequency range can be further improved.

[0442] FIG. 45 is a diagram showing an audio device according to another embodiment of the present specification.

[0443] Figure 45 shows an acoustic device 30 described with reference to Figure 43 further configured with a protective member. In the following description, the protective member will be described in detail, and the remaining configuration is substantially the same as that described with reference to Figures 1 to 34, so the same reference numerals will be used therefor, and duplicated description thereof may be omitted or simplified.

[0444] 45, an audio device 30 according to another embodiment of the present specification may further include a protective member 410. The protective member 410 is substantially the same as the protective member 410 described in FIG 33, and therefore, a duplicated description thereof may be omitted or simplified.

[0445] The protective member 410 according to embodiments of the present disclosure may be disposed on the sound generating module 330. For example, the protective member 410 may cover the sound generating module 330. For example, the protective member 410 may be disposed on the second vibrating device 335. For example, the protective member 410 may cover the second vibrating device 335.

[0446] According to an embodiment of the present specification, the protective member 410 may be made of rubber or sponge, but the embodiment of the present specification is not limited thereto. For example, the rubber may be ethylene propylene diene rubber (or ethylene propylene diene M class rubber), ethylene propylene rubber, or urethane rubber, but the embodiment of the present specification is not limited thereto. For example, the protective member 410 may include a rubber material or may be made of ethylene propylene diene monomer, ethylene propylene rubber, or urethane rubber.

[0447] According to another embodiment of the present specification, the protective member 410 may be made of highly elastic rubber, but the embodiment of the present specification is not limited thereto. For example, the thickness of the protective member 410 may be 0.5 mm to 2 mm, but the embodiment of the present specification is not limited thereto.

[0448] According to an embodiment of the present specification, by configuring the protective member 410 on the connecting member 380 and the sound generating module 330 having different thicknesses, the acoustic characteristics and / or sound pressure characteristics of the low frequency range can be further complemented and the acoustic device 30 can be protected.

[0449] Fig. 46 is a diagram showing an acoustic device according to another embodiment of the present specification. Fig. 46 shows another embodiment of the connecting member 380 described with reference to Fig. 43 and Fig. 44A. Therefore, in the following description, repeated descriptions of the remaining configuration except for the connecting member 380 can be omitted or simplified.

[0450] Referring to FIG. 46, an acoustic device 30 according to another embodiment of the present disclosure may further include a connecting member 380.

[0451] The connecting member 380 may include a first portion and a second portion. The second portion may be an edge portion of the enclosure 310. The second portion may be a portion (or region) between the vehicle interior material 130 and the edge portion of the enclosure 310. The first portion may be a remaining portion of the enclosure 310 excluding the edge portion. For example, the first portion may correspond to a central portion of the enclosure 310 surrounded by a second portion corresponding to the edge portion of the enclosure 310.

[0452] According to an embodiment of the present specification, the first portion of the connecting member 380 may include an opening hole 380o connected to the internal space 313 of the enclosure 310. For example, the first portion may include an opening hole 380o connected to the internal space 313 of the first enclosure 311.

[0453] According to embodiments of the present disclosure, the enclosure 310 or the first enclosure 311 may include at least one region. For example, the enclosure 310 or the first enclosure 311 may include a first region (A1), a second region (A2), and a third region (A3).

[0454] The first region (A1) may correspond to a central portion of the enclosure 310 or the first enclosure 311. The first region (A1) may be in the central portion of the enclosure 310 or the first enclosure 311. The second region (A2) may correspond to an edge portion surrounding the central portion of the enclosure 310 or the first enclosure 311. The third region (A3) may be between the first region (A1) and the second region (A2). For example, the first portion of the coupling member 380 may be in the first region (A1). For example, the second portion of the coupling member 380 may be away from the first portion and in the second region (A2). For example, the second portion of the coupling member 380 may be away from the first region and in the second region (A2). For example, the first portion of the coupling member 380 may be in the central portion of the enclosure 310. For example, the second portion of the coupling member 380 may be away from the first region and in the edge portion of the enclosure 310.

[0455] According to the embodiment of the present specification, the first and second parts of the connecting member 380 may have different thicknesses (T3, T4). For example, the connecting member 380 may include a first and a second part having different thicknesses (T3, T4). In the connecting member 380, the thickness (T3) of the first part may be different from the thickness (T4) of the second part. For example, in the connecting member 380, the thickness (T4) of the second part may be thicker than the thickness (T3) of the first part. For example, the thickness (T3) of the connecting member 380 in the first region (A1) may be different from the thickness (T4) of the connecting member 380 in the second region (A2). For example, the thickness (T4) of the connecting member 380 in the second region (A2) may be thicker than the thickness (T3) of the connecting member 380 in the first region (A1). For example, the connecting member 380 may not be disposed in the third region (A3) between the first region (A1) and the second region (A2) or in the portion between the first portion and the second portion.

[0456] According to the embodiment of the present specification, since the second portion of the connecting member 380 has a thickness (T4) greater than that of the first portion, the edge portion of the connecting member 380 can be connected to or contacted with the vehicle interior material 130 without lifting up. This can prevent the edge portion of the connecting member 380 from lifting up from the vehicle interior material 130, and vibrations within the edge portion of the enclosure 310 can be transmitted to the vehicle interior material 130 without loss of vibration (or vibration transmission) at the edge portion of the enclosure 310. The vibrations at the edge portion of the enclosure 310 increase the vibration area of ​​the vehicle interior material 130, so that the acoustic characteristics of the low-frequency range can be further improved or complemented. Therefore, the sound generated by the vibration of the acoustic device 30 can be transmitted to the vehicle interior material 130 without loss, so that the sound of the low-frequency range can be further improved. For example, sound generated by vibration of the acoustic device 30 may be transmitted to the vehicle interior material 130 through the opening 310o and the edge portion of the enclosure 310, thereby increasing the efficiency of the vibration transmitted from the enclosure 310 to the vehicle interior material 130 and further improving the acoustic characteristics and / or sound pressure characteristics in the low-frequency range.

[0457] According to embodiments of the present disclosure, the connecting member 380 may include a first connecting member 383 and a second connecting member 384 .

[0461] The first and second portions of the connecting member 380 may have different widths (or sizes). The width of the first portion may be smaller than the width of the second portion. For example, the width of the first connecting member 383 in the first region (A1) may be smaller than the width of the second connecting member 384 in the second region (A2). Thus, the first connecting member 383 and the second connecting member 384 may include different sizes (or widths) and different thicknesses.

[0462] Each of the first connecting member 383 and the second connecting member 384 may be a cushion member or a pad member, and the embodiments of the present specification are not limited thereto.

[0463] The first connecting member 383 may include the same material as the second connecting member 384. Each of the first connecting member 383 and the second connecting member 384 may be a highly elastic rubber or the like, and the embodiments of the present specification are not limited thereto. For example, each of the first connecting member 383 and the second connecting member 384 may include a rubber material or be made of ethylene propylene diene rubber (or ethylene propylene diene M class rubber), ethylene propylene rubber, or urethane rubber.

[0464] According to embodiments herein, the width of the connecting member 380 in the second portion may be greater than the width of the coupling member 320. For example, the width of the second connecting member 384 may be greater than the width of the coupling member 320. For example, the width of the connecting member 380 in the second region (A2) may be greater than the width of the coupling member 320.

[0465] According to an embodiment of the present specification, each of the first connecting member 383 and the second connecting member 384 of the connecting member 380 has a compressive force (or contraction force) and an elastic restoring force, and can be contracted or compressed by the connection between the connecting portion 500 and the first enclosure 311. For example, the first connecting member 383 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a first thickness (T3) compressed by the pressure force of the first enclosure 311. The second connecting member 384 disposed (or interposed) between the first enclosure 311 and the vehicle interior material 130 can have a second thickness (T4) compressed by the pressure force of the first enclosure 311.

[0466] The first thickness (T3) of the first connecting member 381 may be different from the second thickness (T4) of the second connecting member 382. The first thickness (T3) of the first connecting member 383 and the second thickness (T4) of the second connecting member 384 may be 0.5 mm or more, and the embodiment of the present specification is not limited thereto. For example, the first thickness (T3) of the first connecting member 383 and the second thickness (T4) of the second connecting member 384 may be 0.5 mm to 3 mm, and the embodiment of the present specification is not limited thereto. For example, the first thickness (T3) of the first connecting member 383 and the second thickness (T4) of the second connecting member 384 may have different thicknesses from each other within a range of 0.5 mm to 3 mm. For example, the second thickness (T4) of the second connecting member 384 may be thicker than the first thickness (T3) of the first connecting member 383 within a range of 0.5 mm to 3 mm.

[0467] The acoustic device 30 according to other embodiments of the present specification may further include an air gap (AG). For example, the air gap (AG) may be in a region between the first portion of the connecting member 380 and the vehicle interior material 130, or in a region between the first portion and the second portion of the connecting member 380. For example, the air gap (AG) may be in a third region (A3) between the first region (A1) and the second region (A2) of the enclosure 310. For example, the air gap (AG) may be in a region between the third region (A3) of the enclosure 310 and the vehicle interior material 130. For example, by providing the air gap (AG) in the third area (A3) between the first area (A1) and the second area (A2) of the enclosure 310, it is possible to separate or minimize interference between the vibrations of the first area (A1) and the second area (A2), thereby increasing the vibration force (or vibration amount) transmitted from the second area (A2) of the enclosure 310, for example, the edge portion, to the vehicle interior material 130. This allows the range (reproduction range) of the low-frequency band to be expanded, and therefore the acoustic characteristics and / or sound pressure characteristics of the low-frequency band can be further improved.

[0468] According to an embodiment of the present specification, by configuring the first and second connecting members 383, 384 including first and second portions having different thicknesses, it is possible to provide an acoustic device 30 having improved acoustic characteristics and / or sound pressure characteristics in the low frequency range. According to an embodiment of the present specification, by configuring the second connecting member 384, it is possible to increase the vibration area (or vibration region) of the roof trim when connecting the acoustic device 30 to the roof trim of a transportation device, so that the acoustic characteristics and / or sound pressure characteristics in the low frequency range can be further improved.

[0469] FIG. 47 is a diagram showing a method of connecting the acoustic device shown in FIG. 46 and a connecting portion according to another embodiment of this specification.

[0470] 46 and 47, according to one embodiment of the present specification, the first connecting member 383 of the connecting member 380 may be connected (or attached) to a central portion (or a first portion) of the enclosure 310 or the first enclosure 311 such that the hole 380o of the enclosure 310 or the first enclosure 311 overlaps (or is connected) with the opening 310o, and the second connecting member 384 of the connecting member 380 may be connected (or attached) to an edge portion (or a second portion) of the enclosure 310 or the first enclosure 311. The enclosure 310 or the first enclosure 311 may be disposed on the vehicle interior material 130 such that the opening 310o overlaps (or is connected) with the hole 135 of the vehicle interior material 130. The coupling portion 500 may be connected or coupled to the audio device 30 or the enclosure 310 through the hole 135 of the vehicle interior material 130 (in the direction of the arrow) in the interior space of the vehicle. For example, the connecting part 500 may be connected or coupled to the audio device 30 or the enclosure 310 through the second hole 135 of the vehicle interior material 130 and the hole 380o of the first connecting member 383 (in the direction of the arrow) in the interior space of the vehicle. For example, the connecting part 500 may be accommodated or inserted into the hole 135 of the vehicle interior material 130, the hole 380o of the first connecting member 383, and the opening 310o of the first enclosure 311 in the interior space of the vehicle. For example, the hook member 504 of the coupling part 500 may be coupled or coupled to the opening 310o of the first enclosure 311. For example, the hook member 504 of the coupling part 500 may be inserted (or accommodated) into the opening 310o of the first enclosure 311 and coupled or coupled to the home part 311g of the first enclosure 311 by a hook coupling manner. Therefore, the first enclosure 311 is connected (or in contact) with the vehicle interior material 130 by connection with the connecting portion 500 and by the first connecting member 383 and the second connecting member 384, and can output sound by vibrating the vehicle interior material 130 through the vibration of the vibration device.

[0471] The first connecting member 383 may have an initial thickness (T3') before compression (or contraction), and may be compressed (or contracted) to a deformed thickness (or compressed thickness) (T3) by the pressure applied from the enclosure 310 by the coupling (or connection) of the coupling part 500 and the enclosure 310. For example, when the coupling part 500 is coupled (or connected) to the enclosure 310, the thickness of the first connecting member 383 may be compressed from the initial thickness (T3') to the compressed thickness (T3) by the pressure applied from the enclosure 310, so that the vibration of the first area (A1) in the first enclosure 311 may be efficiently transmitted to the vehicle interior material 130 via the first connecting member 383. For example, when the acoustic device 30 is separated (or detached) from the vehicle interior material 130 by the separation of the coupling part 500, the first connecting member 383 may be restored from the deformed thickness (T3) to the initial thickness (T3') by the elastic restoring force.

[0472] The second connecting member 384 may have an initial thickness (T2') before compression (or contraction), and may be compressed (or contracted) to a deformed thickness (or compressed thickness) (T2) by the pressure applied from the enclosure 310 when the connecting part 500 and the enclosure 310 are connected (or joined). For example, when the connecting part 500 is connected (or joined) to the enclosure 310, the thickness of the second connecting member 382 may be compressed from the initial thickness (T2') to the compressed thickness (T2) by the pressure applied from the enclosure 310, so that vibrations of the second region (A2) in the first enclosure 311 may be efficiently transmitted to the vehicle interior material 130 via the first connecting member 381 and the second connecting member 382. For example, when the acoustic device 30 is separated (or detached) from the vehicle interior material 130 by separating the coupling portion 500, the second connecting member 382 can be restored from the deformed thickness (T2) to the initial thickness (T2') by the elastic restoring force.

[0473] The vehicle interior material 130 connected (or in contact) with the enclosure 310 or the first enclosure 311 can be deformed to include a bent portion or at least one curved portion by the connection (or coupling) between the coupling portion 500 and the enclosure 310, and thus lifting generated between the edge portion of the enclosure 310 or the first enclosure 311 and the vehicle interior material 130 can be prevented by the second coupling member 384 having a relatively large thickness. As a result, the vibration at the edge portion of the enclosure 310 or the first enclosure 311 caused by the vibration of the vibration device can be transmitted to the vehicle interior material 130 without loss, so that the efficiency of vibration transmitted from the enclosure 310 to the vehicle interior material 130 can be improved, and the acoustic characteristics and / or sound pressure characteristics in the low frequency range can be further improved.

For example, the protective member 410 may include a rubber material or may be made of ethylene propylene diene rubber, ethylene propylene rubber, or urethane rubber.

[0479] According to an embodiment of the present specification, the protective member 410 may be made of highly elastic rubber, but the embodiment of the present specification is not limited thereto. For example, the thickness of the protective member 410 may be 0.5 mm to 2 mm, but the embodiment of the present specification is not limited thereto.

[0480] According to an embodiment of the present specification, by configuring a protective member 410 on the connecting member 380 including the first and second connecting members 383, 384 having different thicknesses (T3, T4) and the sound generating module 330, the acoustic characteristics and / or sound pressure characteristics of the low frequency range can be further complemented and the acoustic device 30 can be protected.

The vibration generator 1310 may vibrate (or displace or drive) a vibrating member (or vehicle interior material) by vibrating (or displacing or driving) the piezoelectric material due to a driving signal (or voice signal or acoustic signal) applied to the piezoelectric material. For example, the vibration generator 1310 may vibrate (or displace or drive) by alternately repeating contraction and / or expansion due to the piezoelectric effect (or piezoelectric properties). For example, the vibration generator 1310 may vibrate (or displace or drive) in the vertical direction (or thickness direction) (Z) by alternately repeating contraction and / or expansion due to the inverse piezoelectric effect of the piezoelectric material. For example, the vibration generator 1310 may vibrate or mechanically displace (or vibrate or drive) a piezoelectric material including a piezoelectric ceramic in response to an electric signal applied from the outside.
