The rear surface (or the lower surface) of the first housing 311 may be connected (or coupled) to the first surface of the vehicle interior material 130.

[0166] The first housing 311 may vibrate based on the drive (or vibration or displacement) of the sound generation module 330, and the vehicle interior material 130 may vibrate based on the vibration of the first housing 311 to generate or output sound. Thus, according to an embodiment of the present disclosure, sound may be generated based on the vibration of the vehicle interior material 130, and the size of the vehicle interior material 130 is larger than the size of the sound device 30, thereby enhancing the sound characteristics and / or the sound pressure level characteristics of the sound including the low-pitched vocal cords generated by the drive (or vibration or displacement) of the sound device 30.

[0167] The second housing 312 may be at the sound generation module 330, with an internal space 313 therebetween. The second housing 312 may be connected to the sound generation module 330, with an internal space 313 therebetween. The second housing 312 may be disposed at or connected to the second surface side (or the front surface side or the upper surface side) opposite to the first surface side of the sound generation module 330, with an internal space 313 therebetween. For example, the second housing 312 may be connected (or coupled) to the peripheral portion of the second surface of the sound generation module 330, with an internal space 313 therebetween.

The second housing 312 may be configured to surround the second surface of the sound generation module 330. The second housing 312 may be configured to cover the second surface of the sound generation module 330.

[0168] The second housing 312 may be at the sound generating module 330, with a second space 313b therebetween. The second housing 312 may be connected to the sound generating module 330, with a second space 313b therebetween.

The second housing 312 may support the second surface of the sound generating module 330, with a second space 313b therebetween.

[0169] For example, the second housing 312 may be configured to have a shape opposite to that of the first housing 311. For example, the first housing 311 and the second housing 312 may be configured to have a symmetric shape or a symmetric structure, with the sound generating module 330 therebetween.

[0170] The vibration device may be disposed in the internal space 313 of the housing 310. The vibration device may be configured to generate sound (or sound pressure level or sound wave) in the internal space 313 of the housing 310.

[0171] According to an embodiment of the present disclosure, the first vibration device 333 may be disposed in the internal space 313 of the housing 310.

The second vibration device 335 may be disposed in the second space 313b of the second housing 312.

[0172] Each of the first vibration device 333 and the second vibration device 335 may vibrate the vibration member 331 to generate sound (or sound pressure level or sound wave) in the internal space 313 of the housing 310. The housing 310 may vibrate based on the sound (or sound pressure level or sound wave) in the internal space 313 of the housing 310, and the vehicle interior material 130 may vibrate based on the vibration of the housing 310 to generate (or output) sound. For example, the vehicle interior material 130 may vibrate based on the sound (or sound pressure level or sound wave) generated in the internal space 313 of the housing 310 through the vibration of the first housing 311 to generate (or output) sound.

For example, the vibration member 331 can be disposed between the first vibration device 333 and the second vibration device 335.

[0174] The vibration member 331 can be disposed or configured at a region between the first housing 311 and the second housing 312 of the housing 310. The vibration member 331 can be configured to divide (or partition) 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 can be divided (or partitioned) 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 can be disposed between the first housing 311 of the housing 310 and the vibration member 331 and can be covered by the vibration member 331. The second space 313b of the internal space 313 can be disposed between the second housing 312 of the housing 310 and the vibration member 331 and can be covered by the vibration member 331.

[0175] For example, the first vibration device 333 and the second vibration device 335 can be at different spaces in the internal space 313 of the housing 310. For example, the first vibration device 333 can be at the first space 313a. For example, the second vibration device 335 can be at the second space 313b.

[0176] The first space 313a can be between the sound generation module 330 and the first housing 311. For example, the first space 313a can be between the first surface of the sound generation module 330 and the first housing 311. The first space 313a can be between the first vibration device 333 and the first housing 311. The second space 313b can be between the sound generation module 330 and the second housing 312. For example, the second space 313b can be between the second surface of the sound generation module 330, which is different (or opposite) from the first surface, and the second housing 312. The second space 313b can be between the second vibration device 335 and the second housing 312. For example, the internal space 313 can be an interstitial space, an air space, a vibration space, a sound space, a sound box, or a sealed space, etc., but the embodiments of the present disclosure are not limited thereto.

[0177] The sound generation module 330 may be configured to be accommodated (or received) in the internal space 313 of the housing 310. The sound generation module 330 may be configured to generate a sound pressure level (or sound or sound wave) in the internal space 313 of the housing 310. The sound generation module 330 may generate a sound pressure level (or sound or sound wave) in the internal space 313 to vibrate the housing 310 and vibrate the vehicle interior material 130 based on the vibration of the housing 310. For example, the sound generation module 330 may be configured to vibrate the first housing 311 of the housing 310 to vibrate the vehicle interior material 130. For example, the sound generation module 330 may generate a sound pressure level (or sound or sound wave) in the internal space 313 of the housing 310 to vibrate the first housing 311, and may vibrate the vehicle interior material 130 based on the vibration of the first housing 311. For example, the sound pressure level (or sound or sound wave) generated in the internal space 313 of the housing 310 based on the driving (or vibration) of the sound generation module 330 may vibrate the housing 310, the vibration of the housing 310 may vibrate the vehicle interior material 130, and the sound or vibration generated based on the vibration of the vehicle interior material 130 may be output to the interior space IS of the vehicle 10.

[0178] The sound device 30 or the housing 310 according to an embodiment of the present disclosure may include an opening 310o.

[0179] The opening 310o may be configured at the first housing 311 to overlap with the sound generation module 330 in the thickness direction Z (or vertical direction) of the sound device 30. The opening 310o may be configured to pass through (or vertically through) the first housing 311 in the thickness direction Z (or vertical direction) of the housing 310. For example, the opening 310o may face or directly face the first surface of the sound generation module 330. The opening 310o may be connected to the internal space 313. For example, the opening 310o may be configured to reduce the air pressure in the internal space 313 of the housing 310. For example, the opening 310o may be connected to the first space 313a. For example, the internal space 313 of the housing 310 may include a space connected to the opening 310o. For example, the internal space 313 of the housing 310 may include the first space 313a connected to the opening 310o.

[0180] The opening 310o may be configured to reduce the air pressure in the internal space 313 of the housing 310. The opening 310o may be configured to reduce the air pressure in the first space 313a of the first housing 311 or the air pressure in the first space 313a provided between the vibration member 331 and the first housing 311. Accordingly, the frequency band of the low-pitched sound source may be extended, and thus the sound characteristics of the low-pitched sound source may be improved. For example, since the pressure (or air pressure) in the first space 313a is reduced by the opening 310o, the displacement amount (or bending force) of the vibration member 331 or the vibration device provided between the vibration member 331 and the first housing 311 may be increased, and thus, the frequency band of the low-pitched sound source may be extended, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched sound source. Accordingly, the sound (or sound pressure level) of the low-pitched sound source generated based on the vibration (or displacement) of the first vibration device 333 and / or the second vibration device 335 may be improved.

[0181] According to an embodiment of the present disclosure, the opening 310o may overlap with the vibration devices 333 and 335. For example, the opening 310o may be provided to correspond to the central portion of the sound generation module 330. For example, the opening 310o may be provided to correspond to the central portion of the vibration devices 333 and 335. For example, the opening 310o may be provided to correspond to the central portion of the first vibration device 333 and the second vibration device 335. For example, the opening 310o may be provided to correspond to the central portion of each of the first vibration device 333 and the second vibration device 335.

[0182] According to an embodiment of the present disclosure, the opening 310o may have a size smaller than that of the first vibration device 333. For example, the opening 310o may have a size smaller than that of the first vibration device 333 provided at the vibration member 331. For example, the opening 310o may include a linear shape having a size (or length) smaller than that of the first vibration device 333 provided at the vibration member 331. For example, the opening 310o may include a linear shape passing through the central portions of the vibration devices 333 and 335, or may include a rectangular shape. For example, the opening 310o may be a hole, a groove, or a slit, but embodiments of the present disclosure are not limited thereto. For example, the opening 310o may be a sound emission portion, a first sound emission port, a sound output portion, a sound output port, a sound output hole, a duct hole, or a vent hole, but embodiments of the present disclosure are not limited thereto.

[0183] The opening 310o can be a space where sound waves generated by the vibration of the sound generation module 330 propagate (or are transmitted) in the internal space 313 of the housing 310 to the interior space IS of the vehicle 10. For example, the vibration of the sound generation module 330 can be transmitted to the interior space IS of the vehicle 10 through the opening 310o. For example, sound waves (or sound) based on the vibration of the sound generation module 330 can be transmitted (or output or emitted or released) to the interior space IS of the vehicle 10 through the opening 310o. For example, vibration or sound generated by the vibration (or displacement) of the vibration member 331 based on the vibration of the vibration devices 333 and 335 can be transmitted (or output or emitted or released) to the interior space IS of the vehicle 10 through the opening 310o. Therefore, the vibration width (or displacement width) of the vibration member 331 based on the vibration of the sound generation module 330 can be increased, and thus, the sound characteristics and / or sound pressure level characteristics generated based on the vibration of the vibration member 331 can be enhanced.

[0184] The first housing 311 including the opening 310o can be arranged closer to the vehicle interior material 130 than the second housing 312. For example, the first housing 311 including the opening 310o can be arranged closer to the vehicle interior material 130 than the second housing 312. Therefore, sound generated based on the vibration of one or more of the first vibration device 333 and the second vibration device 335 can be transmitted (or output or emitted or released) to the vehicle interior material 130 through the opening 310o, and the vehicle interior material 130 can vibrate based on the vibration or sound transmitted through the opening 310o to output the sound to the interior space IS of the vehicle 10. Therefore, sound can be generated based on the vibration of the vehicle interior material 130 having a size larger than the size of the sound device 30, and thus, the sound characteristics and / or sound pressure level characteristics of the tone vocal cords including the bass tone vocal cords generated based on the drive (or vibration) of the sound device 30 can be enhanced.

[0185] The first housing 311 can include a ramp surface (or inclined surface) 311s and an inner surface 311i. The ramp surface 311s can be configured to be inclined between the opening 310o of the first housing 311 and the inner surface 311i. The ramp surface 311s can be configured to guide the sound generated based on the vibration of the sound generation module 330 to the interior space IS of the vehicle 10. Therefore, the sound generated based on the vibration of the sound generation module 330 can be output to the interior space IS of the vehicle 10, and the sound characteristics and / or sound pressure level characteristics of the tone vocal cords including the bass tone vocal cords can be further enhanced. For example, the ramp surface 311s can be a guiding surface or a sound guiding surface, but the embodiments of the present disclosure are not limited thereto.

[0186] The vibration member 331 may be arranged or configured to be spaced apart from the opening 310o. The vibration member 331 may be disposed at the internal space 313 to be spaced apart from the opening 310o.

[0187] According to an embodiment of the present disclosure, the first housing 311 of the housing 310 may be arranged or configured at the first surface (or rear surface) of the vibration member 331. The first housing 311 of the housing 310 may be connected (or coupled) to the first surface of the vibration member 331.

For example, the first housing 311 may be configured at the peripheral portion of the first surface of the vibration member 331 to surround the first surface of the sound generating module 330.

[0188] According to an embodiment of the present disclosure, the second housing 312 of the housing 310 may be arranged or configured at the second surface (or front surface) of the vibration member 331 that is different (or opposite) from the first surface. The second housing 312 may be configured to support the peripheral portion (or edge portion) of the second surface of the vibration member 331. For example, the second housing 312 may be connected (or coupled) to the second surface of the vibration member 331. For example, the second housing 312 may be connected (or coupled) to the peripheral portion of the second surface of the vibration member 331. For example, the second housing 312 may be configured at the peripheral portion of the second surface of the vibration member 331 to cover the second surface of the sound generating module 330. For example, the second housing 312 may be configured at the peripheral portion of the second surface of the vibration member 331 to surround the second surface of the sound generating module 330.

[0189] The sound device 30 according to an embodiment of the present disclosure may further include a coupling member 320. The coupling member 320 may be configured to connect or couple the vibration member 331 and the housing 310 to each other. For example, the coupling member 320 may be between the peripheral portion (or edge portion) of the vibration member 331 and the housing 310. The coupling member 320 may include a first coupling member 321 and a second coupling member 322.

[0190] The first coupling member 321 may be between the vibration member 331 and the first housing 311. The first coupling member 321 may be between the peripheral portion of the vibration member 331 and the first housing 311. The first coupling member 321 may be between the peripheral portion of the vibration member 331 and the peripheral portion (or edge portion) of the first housing 311. For example, the peripheral portion of the first housing 311 may be connected or coupled to the first surface of the vibration member 331 through the first coupling member 321. For example, the peripheral portion of the first housing 311 may be connected or coupled to the peripheral portion of the first surface of the vibration member 331 through the first coupling member 321.

[0191] The second coupling member 322 may be between the vibration member 331 and the second housing 312. The second coupling member 322 may be between the peripheral portion of the vibration member 331 and the second housing 312. The second coupling member 322 may be between the peripheral portion of the vibration member 331 and the peripheral portion (or edge portion) of the second housing 312.

For example, the peripheral portion of the second housing 312 may be connected or coupled to the peripheral portion of the second surface of the vibration member 331 through the second coupling member 322.

[0192] According to an embodiment of the present disclosure, the coupling member 320 may be configured to minimize the transmission of vibrations from the vibration member 331 to the housing 310, or may be configured to minimize the re-vibration of the vibrations of the vibration member 331 being transmitted back to the housing 310. The coupling member 320 may include material properties suitable for blocking the transmission of vibrations from the vibration member 331 to the housing 310. Accordingly, the vibrations of the vibration member 331 may be transmitted through the opening 310o without loss of the vibrations of the vibration member 331. For example, the coupling member 320 may include an elastic material. For example, the coupling member 320 may include an elastic material for vibration absorption (or shock absorption). The coupling member 320 according to an embodiment of the present disclosure may be configured with a silicone resin, a polyurethane material, or a polyolefin material, but embodiments of the present disclosure are not limited thereto.

[0193] The coupling member 320 according to another embodiment of the present disclosure may be configured to minimize the transmission of vibrations from the vibration member 331 to the housing 310 and reduce the reflection of incident sound waves generated based on the vibrations of the vibration member 331.

[0194] Referring to Figure 5 and Figure 5 , the sound device 30 according to an embodiment of the present disclosure may further include a plate member 340.

[0195] Due to the limited space of a vehicle or vehicle equipment, there may be a problem that the thickness of the sound device 30 should be reduced to configure the sound device 30 in the vehicle interior material 130. The thickness of the vibration member 331 may be configured thinly to reduce the thickness of the sound device 30. In the case where the thickness of the vibration member 331 is configured thinly, the sound pressure level output (or generated) by the vibrations of the vibration member 331 vibrated by the driving (or vibration) of the vibration devices 333 and 335 may be reduced. The vibration devices 333 and 335 may be configured as piezoelectric materials, and thus, in the sound pressure level output from the vibration devices 333 and 335, the sound pressure level of the high-pitched vocal cords may be output more than the sound pressure level of the low-pitched vocal cords. Accordingly, the sound pressure level of the low-pitched vocal cords output from the sound device 30 may be reduced. To solve such a problem, the plate member 340 may be configured at the vibration devices 333 and 335.

[0196] The plate member 340 may be at the sound generation module 330. For example, the plate member 340 may be connected to a vibrating device. The plate member 340 may be connected to any one of the first vibrating device 333 and the second vibrating device 335. For example, the plate member 340 may be connected to the second vibrating device 335. The plate member 340 may be spaced apart from the housing 310. For example, the plate member 340 may be spaced apart from the first housing 311. The plate member 340 may be at the other side of the first housing 311. For example, the plate member 340 may be spaced apart from the second housing 312. The plate member 340 may not be connected to or in contact with each of the first housing 311 and the second housing 312, and may be spaced apart from each of the first housing 311 and the second housing 312. The plate member 340 may be between the housing 310 and the sound generation module 330. For example, the plate member 340 may be between the second housing 312 and the second vibrating device 335. The plate member 340 may be at the second space 313b. For example, the plate member 340 may be at the other side different from the first space 313a. For example, the plate member 340 and the sound generation module 330 may be disposed in the internal space 313.

[0197] According to an embodiment of the present disclosure, the plate member 340 may include a plate 342 and a support member 344.

[0198] The plate 342 may be at the sound generation module 330. For example, the plate 342 may be connected to a vibrating device. The plate 342 may be connected to the second vibrating device 335. The plate 342 may be spaced apart from the housing 310. For example, the plate 342 may be spaced apart from the first housing 311. The plate 342 may be at the other side of the first housing 311.

For example, the plate 342 may be at the other side different from the first space 313a.

[0199] The plate 342 may be configured of a material with high density and high Young's modulus, and thus, the plate 342 may cause resonance in a low-pitched sound band. For example, the plate 342 may include a plastic material or a metal material. The plastic material of the plate 342 may be configured as ABS, polycarbonate, polypropylene, etc., but the embodiments of the present disclosure are not limited thereto. The metal material of the plate 342 may be configured as aluminum (Al), stainless steel, etc., but the embodiments of the present disclosure are not limited thereto.

[0200] The support member 344 can be between the plate 342 and the sound generating module 330. The support member 344 can be between the plate 342 and the second vibration device 335.

For example, the support member 344 can include the same material as that of the coupling member 320. The support member 344 can include the same material as that of the coupling member 320, and thus, the vibration of the vibration member 331 can be transmitted to the vehicle interior material through the opening 310o without loss. For example, the support member 344 can be a plate support member, an adhesive member, a connecting member, a fixing member, a spacer member, or a gap spacer, but embodiments of the present disclosure are not limited thereto.

[0201] A gap space (or air gap) AG can also be provided between the plate member 340 and the vibration device. For example, the gap space AG can be or be provided between the plate member 340 and the second vibration device 335. The gap space AG can be or be provided between the plate 342 and the vibration device. For example, the gap space AG can be or be provided between the plate 342 and the second vibration device 335. The gap space AG can increase the vibration force (or vibration displacement amount) of the second vibration device 335. Therefore, the frequency band (reproduction frequency band) of the low-pitched sound band can be expanded, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched sound band can be further improved.

[0202] The gap space AG can overlap with the opening 310o. Therefore, the vibration of the vibration device can be better transmitted to the opening 310o, and the reproduction frequency band of the low-pitched sound band can be more reliable.

[0203] According to an embodiment of the present disclosure, the plate member 340 can be provided in the longitudinal axis direction of the vibration device. The plate member 340 can have a quadrilateral shape with the height and width of the vibration device, the vertical length can be perpendicular to the horizontal length, and the vertical length can be longer than the horizontal length.

For example, the length L1 of the sound generation module 330 may be different from the length L2 of the plate 342. The length L1 of the sound generation module 330 may be longer than the length L2 of the plate member 340. For example, the length L1 of the sound generation module 330 may be longer than the length L2 of the plate 342. The length L2 of the plate member 340 may be 40% to 60% of the length L1 of the sound generation module 330, but embodiments of the present disclosure are not limited thereto. For example, the length L2 of the plate 342 may be 40% to 60% of the length L1 of the sound generation module 330, but embodiments of the present disclosure are not limited thereto. Hereinafter, reference will be made to Figure 3 and Figure 4 describe the sound output characteristics based on the length L2 of the plate member 340 or the plate 342.

[0205] According to an embodiment of the present disclosure, the plate member 340 may have a weight (or mass), and thus may increase the moment of inertia of the vibration member 331 based on the vibration of the vibration device. For example, when the vibration member 331 vibrates based on the vibration of the vibration device, based on the weight of the plate member 340, the plate member 340 may lower the resonance frequency of the vibration member 331, and thus, the frequency characteristics of the low-pitched vocal cords of the sound generated based on the vibration of the vibration member 331 may be increased or enhanced. For example, the plate member 340 may be used as a mass on the vibration device and / or the vibration member 331, and thus may be a weight member or a mass member.

[0206] According to an embodiment of the present disclosure, the plate member 340 may increase the vibration force of the sound generation module 330, and may further enhance the reproduction band of the low-pitched vocal cords based on the resonance of the plate member 340, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords of the sound generation module 330 may be further improved.

[0207] The sound device 30 according to an embodiment of the present disclosure may include a sound generation module 330 having a bimorph structure, and thus, the sound characteristics and / or sound pressure level characteristics of the vocal cords including the low-pitched vocal cords may be enhanced. Since the sound device 30 according to an embodiment of the present disclosure includes a housing 310 including an opening 310o, the air pressure in the internal space 313 of the housing 310 may be reduced, and thus, the vocal cords of the low-pitched vocal cords may be expanded, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords of the vocal cords including the low-pitched vocal cords may be improved.

[0208] Figure 1 A sound device according to another embodiment of the present disclosure is shown.

[0209] Refer toFigure 2 According to another embodiment of the present disclosure, the sound device 30 may include a housing 310, a sound generation module 330, a coupling member 320, and a plate member 340. The descriptions of the housing 310, the sound generation module 330, the coupling member 320, and the plate member 340 may be substantially the same as those in Figure 6 and Figure 6 , and thus, the same reference numerals refer to the same elements, and repeated descriptions are omitted or will be given briefly.

[0210] The sound device 30 according to another embodiment of the present disclosure may further include a connection member 350.

[0211] The connection member 350 may be disposed or configured between the vibrating object and the sound device 30. For example, the connection member 350 may be disposed or configured between the vehicle interior material 130 and the sound generation module 330. The connection member 350 may be configured at the rear surface of the sound device 30. The connection member 350 may be configured at the housing 310. For example, the connection member 350 may be connected to the housing 310. For example, the connection member 350 may be disposed between the housing 310 and the vehicle interior material (or the mounting object). For example, the connection member 350 may be disposed between the vehicle interior material (or the mounting object) and the first housing 311. For example, the connection member 350 may be disposed between the vehicle interior material (or the mounting object) and the rear surface of the first housing 311. For example, the mounting object may be a structure on which the sound device 30 or the housing 310 is mounted. For example, the connection member 350 may be disposed or configured between Figure 3 or Figure 4 the sound device 30 (or the vehicle interior material 130) shown and the housing 310. For example, the connection member 350 may be a first connection member, a first intermediate member, a first cushion member, or a first buffer member, but the embodiments of the present disclosure are not limited thereto.

[0212] The connection member 350 may be configured to transfer the vibration of the first housing 311 to the vehicle interior material 130 based on the vibration of the sound generation module 330. The connection member 350 may be configured to transfer the vibration of the first housing 311 to the vehicle interior material 130 by the sound (or sound wave) generated in the internal space 313 of the housing 310 based on the vibration of the sound generation module 330. Accordingly, the vehicle interior material 130 may vibrate based on the vibration transferred through the connection member 350 to generate (or output) sound.

[0213] According to another embodiment of the present disclosure, the first housing 311 may include an inner surface 311i and an outer surface. The inner surface 311i of the first housing 311 may face the vibration member 331. The outer surface of the first housing 311 may be a surface of the first housing 311 opposite to the inner surface 311i. The connecting member 350 may be connected to the periphery of the opening 310o of the outer surface of the first housing 311.

For example, the tensile strength of the EPDM may be 50 kg / cm 2 to 200 kg / cm 2 , but the embodiments of the present disclosure are not limited thereto. For example, the connecting member 350 may include high-elasticity rubber or high-elasticity EPDM, but the embodiments of the present disclosure are not limited thereto. For example, the connecting member 350 may be configured with a material different from that of the support member 344.

[0215] According to an embodiment of the present disclosure, the connecting member 350 is configured as a relatively rigid material (or hard material), and thus, the vibration of the first housing 311 may be transmitted to the vehicle interior material 130 based on the vibration of the vibration device. Therefore, the vehicle interior material 130 may vibrate based on the vibration transmitted through the connecting member 350 to generate sound. For example, when the connecting member 350 is configured as a relatively rigid material, the vehicle interior material 130 connected to the connecting member 350 may be a vibration plate for generating (or outputting) sound. For example, when the connecting member 350 is configured as a relatively rigid material, the vibration of the first housing 311 may be more effectively transmitted to the vehicle interior material 130.

[0216] According to an embodiment of the present disclosure, the connecting member 350 may transfer the heat generated when the sound generation module 330 vibrates to the vehicle interior material 130, thereby dissipating the heat generated when the sound generation module 330 vibrates.

[0217] According to an embodiment of the present disclosure, the connection member 350 may further include a hole 350o. For example, the connection member 350 may further include a hole 350o connected to an opening 310o at the housing 310 or the first housing 311. The hole 350o may be arranged to correspond to (or overlap with) the opening 310o. Accordingly, the sound based on the vibration of the sound generation module 330 (or the sound (or sound wave) in the internal space 313) may be output to the interior space of the vehicle by (or through) the opening 310o and the hole 350o. The hole 350o may have the same shape as the opening 310o, but the embodiments of the present disclosure are not limited thereto. For example, the hole 350o may be a through hole, a first through hole, a first hole, an opening, an opening hole, a slit, a groove, a connection hole, or an intermediate hole, but the embodiments of the present disclosure are not limited thereto.

[0218] According to an embodiment of the present disclosure, the connection member 350 may be protected by a release film (or protective film) 351. The release film 351 may be attached to the adhesive surface of the connection member 350. When the sound device 30 including the connection member 350 is installed on the vehicle interior material (or installation object) 130, the release film 351 may be released (or removed) from the connection member 350.

[0219] The connection member 350 according to an embodiment of the present disclosure may be disposed (or inserted) between the vehicle interior material 130 and the sound device 30. Accordingly, no vibration sound (or rattling sound) may occur between the vehicle interior material 130 and the sound device 30, and thus, the sound characteristics and / or sound pressure level characteristics of the sound device 30 may be improved. In addition, the connection member 350 may reduce the heat generated when the sound generation module 330 vibrates. Furthermore, since the sound device 30 is coupled to or installed on the vehicle interior material 130 through the coupling portion 500, no vibration sound (or rattling sound) may occur between the sound device 30 and the vehicle interior material 130, and thus, the sound characteristics and / or sound pressure level characteristics of the sound device 30 may be improved.

The soft member 360 may be connected to the periphery of the opening 310o of the outer surface of the first housing 311. For example, the soft member 360 may be connected to the periphery of the opening 310o of the outer surface of the first housing 311 and the vehicle interior material 130.

[0225] According to an embodiment of the present disclosure, the soft member 360 may be configured with a material different from the connecting member 350 described above with reference to Figure 3 The elasticity (or Young's modulus) of the soft member 360 may be configured with a material different from the elasticity (or Young's modulus) of the connecting member 350. For example, the soft member 360 may be configured with a material having low elasticity. The soft member 360 may be configured with a smooth material (or soft material). For example, the soft member 360 may be ethylene propylene rubber or polyurethane rubber, but embodiments of the present disclosure are not limited thereto. For example, the ethylene propylene rubber may be ethylene propylene diene monomer (EPDM), and as the foaming rate varies in the EPDM, the ethylene propylene rubber may be configured with EPDM having low elasticity, but embodiments of the present disclosure are not limited thereto.

In addition, the first housing 311 of the housing 310 may vibrate due to the sound (or sound wave) generated in the internal space 313 based on the vibration of the sound generation module 330, and the vibration of the first housing 311 causes the vehicle interior material 130 including one or more bent portions 136 and a flat portion to vibrate through the soft member 360, and the sound generated based on the vibration of the vehicle interior material 130 may be output to the interior space of the vehicle.

[0228] According to an embodiment of the present disclosure, the soft member 360 may be protected by a release film (or protective film) 361.

[0229] In the sound device 30 according to another embodiment of the present disclosure, the soft member 360 is disposed (or inserted) between the housing 310 and the vehicle interior material 130, and thus, no vibration sound (or rattling sound) may occur between the housing 310 and the vehicle interior material 130, thereby improving the sound characteristics and / or sound pressure level characteristics of the sound device 30. In the sound device 30 according to another embodiment of the present disclosure, since the external impact applied to the housing 310 may be absorbed by the soft member 360, the sound device 30 may be protected from external impacts, damage to the sound device 30 may be prevented, and the durability and reliability of the sound device 30 may be enhanced.

The descriptions of the housing 310, the sound generation module 330, the coupling member 320, and the plate member 340 may be substantially the same as the descriptions of Figure 10 , and thus, the same reference numerals refer to the same elements, and the repeated descriptions are omitted, or will be briefly given below.

[0241] The sound device 30 according to another embodiment of the present disclosure may further include a connection member 350. The description of the connection member 350 may be substantially the same as that of Figure 10 and thus, the repetitive description is omitted or will be briefly given below.

[0242] The connection member 350 according to another embodiment of the present disclosure may be provided at the rear surface of the housing 310. The vehicle interior material 130 may be connected or coupled to the housing 310 through the connection member 350. For example, the connection member 350 may be provided at the rear surface of the first housing 311. For example, the connection member 350 may be connected or coupled to the rear surface of the first housing 311. The connection member 350 may be provided between the housing 310 and the vehicle interior material 130. For example, the connection member 350 may be provided between the first housing 311 and the vehicle interior material 130. For example, the vehicle interior material 130 may be connected or coupled to the housing 310 through the connection member 350. For example, the vehicle interior material 130 may be connected or coupled to the rear surface of the first housing 311 through the connection member 350. Thus, the sound device 30 or the housing 310 may be connected or coupled to the vehicle interior material 130 through the connection member 350. For example, the connection member 350 may be provided or configured at Figures 3 to 5 or Figure 6 between the sound device 30 (or the vehicle interior material 130) and the housing 310 as shown.

[0243] The connection member 350 may be configured to transfer the vibration of the first housing 311 to the vehicle interior material 130 based on the vibration of the sound generation module 330. The connection member 350 may be configured to transfer the vibration of the first housing 311 to the vehicle interior material 130 through the sound (or sound wave) generated in the internal space 313 of the housing 310 based on the vibration of the sound generation module 330. Thus, the vehicle interior material 130 may vibrate based on the vibration transferred through the connection member 350 to generate (or output) sound.

[0244] According to an embodiment of the present disclosure, the connection member 350 may include a relatively rigid material (or hard material) and thus may transfer the vibration of the first housing 311 to the vehicle interior material 130 based on the vibration of the vibration device. Thus, the vehicle interior material 130 may vibrate based on the vibration transferred through the connection member 350 to generate sound. For example, when the connection member 350 includes a relatively rigid material (or hard material), the vehicle interior material 130 connected to the connection member 350 may be a vibration plate for generating (or outputting) sound. For example, when the connection member 350 includes a relatively rigid material (or hard material), the vibration of the first housing 311 may be more effectively transferred to the vehicle interior material 130.

[0245] According to an embodiment of the present disclosure, the connection member 350 may transfer the heat generated when the sound generation module 330 vibrates to the vehicle interior material 130, thereby dissipating the heat generated when the sound generation module 330 vibrates.

For example, the plurality of holes 135 may be arranged at equal or different intervals (or distances). The hole 135 may be arranged to correspond to (or overlap with) the opening 310o and / or the hole 350o. For example, the hole 135 may be received in the opening 310o and / or the hole 350o (or inside the opening 310o and / or the hole 350o). For example, the hole 135 may be a through hole, a third through hole, an opening, an open hole, a slit, a groove, a sound hole, a sound discharge hole, or a sound output hole, but the embodiments of the present disclosure are not limited thereto.

[0248] According to an embodiment of the present disclosure, the sound generated based on the vibration of the sound generation module 330 may be output to the interior space of the vehicle by (or through) the opening 310o, the hole 350o of the connection member 350, and the hole 135 of the vehicle interior material 130. In addition, the sound device 30 or the housing 310 may vibrate the vehicle interior material 130 by (or through) the connection member 350 to output sound to the interior space of the vehicle based on the vibration of the vehicle interior material 130.

[0249] According to another embodiment of the present disclosure, for the sound device 30, the connecting member 350 is disposed (or inserted) between the housing 310 and the vehicle interior material 130, and thus, no vibration sound (or flutter sound) may occur between the housing 310 and the vehicle interior material 130, thereby improving the sound characteristics and / or sound pressure level characteristics of the sound device 30. Additionally, according to another embodiment of the present disclosure, for the sound device 30, the heat generated when the sound generation module 330 vibrates can be dissipated to the vehicle interior material 130 through the connecting member 350, thereby preventing the performance of the vibration devices 333 and 335 from being degraded due to heat.

The soft member 360 may be disposed between the housing 310 and the vehicle interior material 130. For example, the soft member 360 may be disposed between the first housing 311 and the vehicle interior material 130. For example, the vehicle interior material 130 may be connected or coupled to the housing 310 through the soft member 360. For example, the vehicle interior material 130 may be connected or coupled to the rear surface of the first housing 311 through the soft member 360. Thus, the sound device 30 or the housing 310 may be connected or coupled to the vehicle interior material 130 through the soft member 360.

[0254] According to another embodiment of the present disclosure, the vehicle interior material 130 may include at least one or more bent portions (or zigzag portions or uneven portions) 136. The soft member 360 may be configured to correspond to at least one or more bent portions 136. The soft member 360 may be in contact with at least one or more bent portions 136. For example, the vehicle interior material 130 may include at least one or more bent portions 136 that contact the soft member 360.

The soft member 360 may directly contact the entire vibration region of the vehicle interior material 130. The soft member 360 may directly contact at least one or more bent portions 136.

[0255] According to an embodiment of the present disclosure, the soft member 360 may directly contact at least one or more bent portions 136 without a separate adhesive member or a separate intermediate member (or medium). For example, the soft member 360 may directly contact the entire vibration region of the vehicle interior material 130 without a separate adhesive member or a separate intermediate member (or medium). The vibration generated by the sound generation module 330 may be transmitted to the entire vibration region of the vehicle interior material 130 including at least one or more bent portions 136 and flat portions through the soft member 360. Accordingly, sound may be generated (or output) based on the vibration of the entire vibration region of the vehicle interior material 130, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the sound including the low-pitched vocal cords generated by the sound generation module 330.

The hole 135 may be arranged to correspond to (or overlap with) the opening 310o and / or the hole 360o. For example, the hole (or holes) 135 may be received in (or within) the opening 310o and / or the hole 360o.

[0261] According to an embodiment of the present disclosure, the sound generated based on the vibration of the sound generation module 330 may be output to the interior space of the vehicle through the opening 310o, the hole 360o of the soft member 360, and the hole 135 of the vehicle interior material 130. In addition, the sound device 30 or the housing 310 may vibrate the vehicle interior material 130 by (or through) the soft member 360 to output sound to the interior space of the vehicle based on the vibration of the vehicle interior material 130. Furthermore, since the external impact applied to the sound device 30 or the housing 310 can be absorbed by the soft member 360, the sound device 30 can be protected from external impacts.

For example, the connection member 380 may include a material having an adhesive force different from that of the first coupling member 321. Since the connection member 380 includes a material having an adhesive force different from that of the first coupling member 321, the separation or disassembly process (or rework) of the connection member 380 from the vehicle interior material 130 can be easily performed during the separation or disassembly process (or rework) of the sound device 30 attached to the vehicle interior material 130. Therefore, the process of attaching or installing the sound device 30 on the vehicle interior material 130 or the process of separating or attaching / detaching the sound device 30 from the vehicle interior material 130 can be easily performed.

[0369] The connection member 380 may be coupled (or attached) to the rear surface of the housing 310 and may contact (or surface-contact) the outer surface of the vehicle interior material 130, but the embodiments of the present disclosure are not limited thereto. For example, in the case where the connection member 380 is coupled (or attached) to the rear surface of the housing 310 and simply contacts (or surface-contacts) the outer surface of the vehicle interior material 130, during the process of separating and disassembling (or reworking) the sound device 30 from the vehicle interior material 130, the process of separating or disassembling (or reworking) the connection member 380 from the vehicle interior material 130 can be easily performed without damaging the sound device 30 or the vehicle interior material 130. For example, the outer surface of the vehicle interior material 130 may be a second surface, an outer surface, a front surface, or an upper surface.

[0374] According to an embodiment of the present disclosure, the connecting member 380 may further include a hole 380o. For example, the connecting member 380 may further include a hole 380o connected to the opening 310o at the housing 310 or the first housing 311.

[0375] The hole 380o may be set to correspond to (or overlap with) the opening 310o. The hole 380o may have the same shape as the opening 310o, but embodiments of the present disclosure are not limited thereto. For example, the hole 380o may have the same shape as the opening 310o and may have a size larger than the size of the opening 310o. Accordingly, the sound based on the vibration of the sound generation module 330 may be output to the interior space IS of the vehicle by (or through) the opening 310o and the hole 380o. For example, the hole 380o may be a through hole, a fourth through hole, an opening, an opening hole, a slit, a groove, a connection hole, or an intermediate hole, but embodiments of the present disclosure are not limited thereto.

[0376] According to an embodiment of the present disclosure, the hole 380o may correspond to (or overlap with) 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 set to correspond to the opening 310o. The hole 380o of the connection 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. Accordingly, the sound based on the vibration of the sound generation module 330 may be output to the interior space IS of the vehicle by (or through) the opening 310o, the hole 380o, and the hole 135.

[0377] Refer to Figure 20 and Figure 20 FIGS., the thickness T1 of the connection member 380 may be different from the thickness of at least one of the first coupling member 321 and the second coupling member 322. For example, the thickness T1 of the connection 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 connection member 380 may be 0.5 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the thickness T1 of the connection member 380 may be 0.5 mm to 3 mm, but embodiments of the present disclosure are not limited thereto.

[0378] According to another embodiment of the present disclosure, the connecting member 380 may have a compressive force (or a contraction force) and an elastic restoring force, and may contract or compress through the 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.

[0379] As Figure 20 shown, the connecting member 380 may have an initial thickness T1' before compression (or contraction), and may be compressed (or contracted) to have a Figure 21 shown deformed thickness (or compressive 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. For example, when the sound device 30 is connected to the vehicle interior material 130 through the coupling portion 500, or when the assembly and / or rework is completed, the thickness of the connecting member 380 may be compressed from the initial thickness T1' to the compressive thickness T1, and thus, the vibration of the housing 310 may be effectively transmitted to the vehicle interior material 130. For example, when the sound device 30 is separated (or disassembled) from the vehicle interior material 130 by disassembling the coupling portion 500, the connecting member 380 may be restored from the deformed thickness (or compressive thickness) T1 to the initial thickness T1' by the elastic restoring force.

[0380] Referring to Figure 22 and Figure 21 , the coupling portion 500 may be connected or coupled to the sound device 30 through the hole 135 of the vehicle interior material 130 (in the arrow direction), the hole 380o of the connecting member 380, and the opening 310o of the first housing 311. For example, in the inner space of the vehicle, the coupling portion 500 may be connected or coupled to the opening 310o of the first housing 311 through the 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 inner space of the vehicle, the coupling portion 500 may be connected or coupled to the sound device 30 or the housing 310 through the hole 135 of the vehicle interior material 130 (in the arrow direction). For example, in the inner space of the vehicle, the coupling portion 500 may be received 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 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 310o of the first housing 311, and may be connected or coupled to the groove portion 311g of the first housing 311 through a hook coupling scheme.

[0381] Figure 22Shows a sound device according to another embodiment of the present disclosure.

[0382] Referring Figure 1 to 20 , an interior vehicle material 130 according to another embodiment of the present disclosure may include at least one or more bent portions (or zigzag portions) 136. The connecting member 380 may be configured to correspond to at least one or more bent portions 136. The connecting member 380 may contact at least one or more bent portions 136. The connecting member 380 may be in direct contact with at least one or more bent portions 136. For example, the connecting member 380 may be in direct contact with at least one or more bent portions 136 without a medium or an intermediate member.

[0383] The sound device 30 or the housing 310 may be connected or coupled to at least one or more bent portions 136 of the interior vehicle material 130 through the connecting member 380. For example, the connecting member 380 may be disposed between the housing 310 and at least one or more bent portions 136 of the interior vehicle material 130. For example, the connecting member 380 may be disposed between the first housing 311 and at least one or more bent portions 136 of the interior vehicle material 130. For example, the first housing 311 may be connected or coupled to at least one or more bent portions 136 of the interior vehicle material 130 through the connecting member 380.

[0384] Referring Figure 1 to 20 , the thickness T1 of the connecting member 380 may be different from the thickness of at least one of the first coupling member 321 and the second coupling member 322. For example, the thickness 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 more, but embodiments of the present disclosure are not limited thereto. For example, the thickness T1 of the connecting member 380 may be from 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 that is compressed (or shrunk) from the Figure 1 to 20<\b r>Figure 21 initial thickness T1' shown due to the coupling force between the coupling portion 500 and the first housing 311. Accordingly, based on the coupling force between the coupling portion 500 and the first housing 311, the connecting member 380 may be in surface contact with the interior vehicle material 130 including at least one or more bent portions 136.

[0385] According to an embodiment of the present disclosure, the sound based on the vibration of the sound generation module 330 can be output to the interior space of the vehicle by (or through) the opening 310o, the hole 380o of the connection member 380, and the hole 135 of the vehicle interior material 130. Additionally, according to an embodiment of the present disclosure, the vibration of the housing 310 or the first housing 311 caused by the sound (or sound pressure level or sound wave) based on the vibration of the sound generation module 330 can be effectively transmitted to the vehicle interior material 130 including at least one or more bent portions 136 through the connection member 380 without vibration loss, and the vehicle interior material 130 including at least one or more bent portions 136 can vibrate based on the vibration of the housing 310 or the first housing 311 transmitted through the connection 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 cords can be further improved.

[0386] The sound device 30 according to another embodiment of the present disclosure may include a housing 310 and a connection member 380. Accordingly, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be further improved, and the attachment or detachment process of the sound generation module 330 attached to the vehicle interior material 130 through the connection member 380 configured as a rubber material can be easily performed.

[0387] Figure 23 A sound device according to another embodiment of the present disclosure is shown. Figure 23 The interior of a sound device according to another embodiment of the present disclosure is shown. Figures 1 to 22 and Figure 1 to 22 shown in the above reference Figure 23 describes an embodiment in which one or more holes are additionally configured in the sound device 30. Accordingly, in the following description, one or more holes will be described in detail, and other elements may be substantially the same as the elements described above with reference to Figures 1 to 22 the description, and thus, the same reference numerals refer to the same elements, and repeated descriptions are omitted or will be briefly given below.

[0388] Referring to Figure 3 , the sound device 30 according to another embodiment of the present disclosure may further include one or more holes 331o.

[0389] The vibration member 331 may include one or more holes 331o at the periphery of the vibration device. The one or more holes 331o may be configured at the vibration member 331. The one or more holes 331o may be configured to pass through the vibration member 331. The one or more holes 331o may be configured to pass through the vibration member 331 in the thickness direction Z of the vibration member 331. For example, the 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.

[0390] The sound generation module 330 according to an embodiment of the present disclosure may include a vibration member 331 having one or more holes 331o and vibration devices 333 and 335 configured at the vibration member 331.

[0391] The one or more holes 331o may be configured to regulate the flow of air in the internal space 313 of the housing 310. For example, the one or more holes 331o may perform control such that air flows in the internal space 313 of the housing 310 that is spatially separated from each other by the vibration member 331. For example, the one or more holes 331o may be configured to regulate the flow of air in the internal space 313 of the housing 310 between a first space 313a and a second space 313b that are spatially separated from each other by the vibration member 331. For example, the one or more holes 331o may be through holes, fifth through holes, first air holes, first ventilation holes, first air flow holes, first duct holes, first connection holes, first communication holes, or first space connection portions, but the embodiments of the present disclosure are not limited thereto.

[0392] One or more holes 331o according to an embodiment of the present disclosure may be configured in a polygonal shape, such as a circular shape, an oval shape, or a quadrilateral shape, but the embodiments of the present disclosure are not limited thereto.

[0393] One or more holes 331o may be configured to reduce the air pressure in the internal space 313 of the housing 310. For example, one or more holes 331o may be connected to each other through the first space 313a and the second space 313b. For example, one or more holes 331o may be configured to connect the first space 313a and the second space 313b that are spatially separated from each other by the vibration member 331 at the internal space 313 of the housing 310. For example, the first space 313a and the second space 313b of the internal space 313 within the housing 310 may be connected (or communicated) with each other through one or more holes 331o. For example, one or more holes 331o may 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. Accordingly, the frequency band (reproduction band) of the low-pitched sound source can be extended, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched sound source can be improved. In addition, the sound generation module 330 may vibrate more stably through one or more holes 331o at the vibration member 331, and thus, the sound characteristics and / or sound pressure level characteristics can be further improved.

[0394] According to an embodiment of the present disclosure, one or more holes 331o may be provided adjacent to the vibration devices 333 and 335. For example, one or more holes 331o may be provided at the periphery of each of the vibration devices 333 and 335. For example, one or more holes 331o may be provided adjacent to the side surfaces of each of the vibration devices 333 and 335. For example, the distance between one or more holes 331o and each of the vibration devices 333 and 335 may be less than the distance between one or more holes 331o and the side wall (or side surface) of the housing 310. For example, when one or more holes 331o are provided at positions away from each of the vibration devices 333 and 335, the sound characteristics and / or sound pressure level characteristics of the low-pitched sound source can be further improved.

[0395] According to an embodiment of the present disclosure, one or more holes 331o may be configured at a vibration member 331 adjacent to vibration devices 333 and 335, with the vibration devices 333 and 335 therebetween. For example, the vibration member 331 may include a first peripheral region adjacent to a first side surface of each of the vibration devices 333 and 335, and a second peripheral region adjacent to a second side of each of the vibration devices 333 and 335 opposite the first side. For example, with respect to a 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 peripheral region and the second peripheral region may be a hole region or a non-arrangement region of each of the vibration devices 333 and 335, and the vibration region may be an arrangement (or setting) region of the vibration devices 333 and 335. For example, one or more holes 331o may be configured in each of the first peripheral region and the second peripheral region of the vibration member 331 to have a symmetric structure (or a horizontal symmetric structure or a left-right symmetric structure) or an asymmetric structure (or a horizontal asymmetric structure or a left-right asymmetric structure) with respect to the vibration devices 333 and 335.

[0396] According to an embodiment of the present disclosure, each of the vibration devices 333 and 335 may include a long side and a short side. The distance (or separation distance or shortest distance) between one or more holes 331o and the short sides of the vibration devices 333 and 335 may represent a ratio of the short side lengths of the vibration devices 333 and 335. According to an embodiment of the present disclosure, the distance between one or more holes 331o and the vibration devices 333 and 335 may be 60% or less of the short side lengths of the vibration devices 333 and 335.

[0397] One or more holes 331o may be arranged 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, one or more holes 331o may be arranged closer to the vibration devices 333 and 335 than the first coupling member 321 and the second coupling member 322. Accordingly, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords may be enhanced.

[0398] According to an embodiment of the present disclosure, one or more holes 331o do not overlap with the opening 310o. For example, one or more holes 331o may be arranged to be spaced apart from the opening 310o. Accordingly, the sound generated in the second space 313b based on the vibration (or drive) of the vibration devices 333 and 335 may be output to the first space 313a through one or more holes 331o, and the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords may be enhanced.

[0399] According to an embodiment of the present disclosure, one or more holes 331o may output sound (or rear sound), which is generated based on the vibrations of vibration devices 333 and 335, and is released to the rear surface (or rearward direction) of the vibration member 331 through the opening 310o of the first housing 311. Therefore, the sound generated based on the vibrations (or driving) 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) may be output to the first space 313a through the one or more holes 331o, and may be output (or radiated) through the opening 310o of the first housing 311 and the hollow portion 501 of the coupling portion 500, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords may be further enhanced. According to an embodiment of the present disclosure, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords (e.g., 400 Hz or lower) may be further enhanced through the one or more holes 331o at the vibration member 331.

Figures 18 to 20 An embodiment achieved by modifying the housing of the sound device 30 described above with reference to Figure 24 is shown. Therefore, in the following description, the housing will be described in detail, and other elements may be substantially the same as the elements described above with reference to Figure 24 and thus, the same reference numerals refer to the same elements, and repeated descriptions may be omitted or will be briefly given below.

[0401] With reference to Figure 23 , in a sound device according to another embodiment of the present disclosure, the housing 310 may include a first housing 311.

The first surface may be the surface facing the housing 310. The vehicle interior material (or mounting object) 130 may include holes 135 disposed at the first surface and the second surface. For example, the holes 135 of the vehicle interior material 130 may be configured to pass through the first surface and the second surface.

[0433] According to another embodiment of the present disclosure, the chamfered portion 503a may include a non-rectangular shape (or non-right-angled shape). For example, the chamfered portion 503a may be configured such that the corner portion between the hollow member 502 and the latch member 503 has a non-rectangular shape. For example, the chamfered portion 503a may include one or more of a curved shape (or circular shape) and a ramp surface. For example, the chamfered portion 503a may have a curvature. The chamfered portion 503a may be configured by a chamfering process, but the embodiments of the present disclosure are not limited thereto.

[0434] Referring to Figure 25, the coupling part 500 may include a first side part (or lower surface) 500a and a second side part (or upper surface) 500b. The second side part 500b may be opposite to the first side part 500a. For example, the chamfered part 503a may be disposed between the second side part 500b and the hollow part 501. For example, the chamfered part 503a may be disposed in a non-rectangular shape in a region (or corner region) between the inner surface (or internal surface) of the hollow member 502 and the upper surface of the hook member 503. For example, the hollow part 501 may be connected to the internal space 313 through the opening 310o of the housing 310.

[0435] According to another embodiment of the present disclosure, the hollow part 501 may have a "1" shape, but the embodiments of the present disclosure are not limited thereto. The hollow part 501 may have a "1" shape parallel to the short side direction or the second direction Y of the housing 310, but the embodiments of the present disclosure are not limited thereto.

For example, the long axis of the hollow part 501 may be parallel to the short side direction or the second direction Y of the housing 310, but the embodiments of the present disclosure are not limited thereto. For example, the short axis of the hollow part 501 may be parallel to the first direction X or the long side direction of the housing 310, but the embodiments of the present disclosure are not limited thereto. For example, the hollow part 501 may have a cross-shaped (+) shape or a star-shaped (*) shape described above Figure 26 , but the embodiments of the present disclosure are not limited thereto. The shape of the chamfered part 503a may be applied identically based on various shapes of the hollow part 501.

[0436] According to another embodiment of the present disclosure, the coupling part 500 may include a hollow part 501 having a specific width (or first width) W. The hollow part 501 of the coupling part 500 may be configured to have a specific width W. For example, the width W of the hollow part 501 may be the short axis length of the hollow part 501. For example, the width W of the hollow part 501 or the short axis length of the hollow part 501 may be 1 mm or more, but the embodiments of the present disclosure are not limited thereto. For example, the width W of the hollow part 501 or the short axis length of the hollow part 501 may be 1 mm to 5 mm or less, but the embodiments of the present disclosure are not limited thereto.

[0437] According to an embodiment of the present disclosure, as the width W of the hollow portion 501 increases, the sound pressure level can be enhanced, but dust or particles from the outside can flow into the internal space of the housing 310. According to an embodiment of the present disclosure, the width W of the hollow portion 501 can be 1 mm or more, but the embodiments of the present disclosure are not limited thereto. For example, the width W of the hollow portion 501 can be 1 mm to 5 mm to reduce or minimize the inflow of dust or particles from the outside, but the embodiments of the present disclosure are not limited thereto.

[0438] According to an embodiment of the present disclosure, since the width W of the hollow portion 501 is configured to be 1 mm or more, sound characteristics and / or sound pressure level characteristics can be enhanced in a tone band including a low-tone vocal band, and peaks and / or dips in a high-tone vocal band can be improved, thereby enhancing the balance characteristics of the sound pressure level and / or the flatness characteristics of the sound pressure level. According to an embodiment of the present disclosure, since the width W of the hollow portion 501 is configured to be 1 mm to 5 mm or less, the inflow of dust or particles from the outside can be reduced or minimized.

[0439] According to another embodiment of the present disclosure, the coupling portion 500 may include a latch member 503 having a specific length L (or a second width). For example, the latch member 503 may be configured to have a specific length L. For example, the length L of the latch member 503 may be a length extending from the outer surface (or outer circumferential surface) of the hollow portion 501 in a direction parallel to the vehicle interior material 130. For example, the length L of the latch member 503 may be a length extending from the lower outer surface of the hollow member 502 in a direction parallel to the vehicle interior material 130 (or a first direction). The latch member 503 having the length L may overlap at least one or more of the vehicle interior material 130, the connection member 380, and the housing 310. For example, the length L of the latch member 503 may be the same as the short-side length of the hollow portion 501.

[0440] As the length L of the coupling portion 500 or the latch member 503 decreases, the sound pressure level characteristics can be enhanced. According to an embodiment of the present disclosure, the length L of the latch member 503 can be 10 mm or more, but the embodiments of the present disclosure are not limited thereto. For example, the length L of the latch member 503 can be 10 mm or more and less than 19 mm, but the embodiments of the present disclosure are not limited thereto. For example, when the length L of the latch member 503 is less than 10 mm, the dips and / or peaks of the sound can be improved, but there may be a problem that it is difficult to equip a sound device in the roof trim of a vehicle device.

[0441] According to an embodiment of the present disclosure, since the length L of the latch member 503 is configured to be 10 mm or greater and less than 19 mm, sound characteristics and / or sound pressure level characteristics can be enhanced in a tone vocal band including a low-tone vocal band, and peaks and / or dips at specific frequencies in a high-tone vocal band can be improved, thereby enhancing the balance characteristics of the sound pressure level or the flatness characteristics of the sound pressure level.

[0442] According to another embodiment of the present disclosure, since the coupling part 500 is configured to include one or more of the width W of the hollow part 501 and the length L of the latch member 503, the sound characteristics and / or sound pressure level characteristics of the sound device 30 can be further enhanced.

[0443] Referring together Figure 21 , the housing 310 may include a protrusion 315. For example, the protrusion 315 may protrude from the housing 310 or the first housing 311 to surround the opening 310o. For example, the protrusion 315 may protrude from the first housing 311 or the rear surface (or outer surface) 311r of the housing 310 to surround the opening 310o. Accordingly, the protrusion 315 may include a hollow hole (or hole or opening hole) 315o connected to (or overlapping with) the opening 310o. The hollow part 501 may be received in the hollow hole 315o of the protrusion 315 and may be connected to the internal space 313 through the hollow hole 315o and the opening 310o. For example, the hook member 504 may be received or inserted into the opening 310o of the first housing 311 or the housing 310 through the vehicle interior material 130 (or the object to be mounted) and the protrusion 315. The hook member 504 may be connected or coupled to the inner surface 311i of the first housing 311 or the housing 310. For example, the hook member 504 may be coupled (or connected) to the groove portion 311g of the housing 310 through a hook coupling scheme in the internal space 313 of the housing 310.

[0444] According to another embodiment of the present disclosure, the sound device 30 may be configured to include one or more of the shape of the coupling part 500, the width W of the coupling part 500, and the length L of the coupling part 500, thereby providing a sound device 30 in which sound characteristics and / or sound pressure level characteristics are further enhanced.

[0445] According to another embodiment of the present disclosure, since the coupling part 500 is configured to have a circular shape or a ramp surface, sound characteristics and / or sound pressure level characteristics in a vocal band of a sound including a low-tone vocal band can be enhanced, and peaks and / or dips in a high-tone vocal band can be improved, thereby enhancing the balance characteristics of the sound pressure level or the flatness characteristics of the sound pressure level.

[0446] Figure 22 A sound device according to another embodiment of the present disclosure is shown.Figure 28 The shape of the chamfered portion 503a according to an embodiment of the present disclosure is shown.

[0447] Referring to Figure 28 , a sound device 30 according to another embodiment of the present disclosure may include a housing 310 and a sound generation module 330. The descriptions of the housing 310 and the sound generation module 330 may be substantially the same as those of Figure 28 , and thus, the same reference numerals refer to the same elements, and the repeated descriptions are omitted or will be briefly given below.

[0448] A sound device 30 according to another embodiment of the present disclosure may include a coupling portion 500 connected to an interior material 130 of a vehicle. The description of the coupling portion 500 may be the same as that of Figure 25 or Figure 25 and Figure 23 , and thus, the same reference numerals refer to the same elements, and the repeated descriptions are omitted or will be briefly given below.

[0449] The chamfered portion 503a according to an embodiment of the present disclosure may include a non-rectangular shape. For example, the chamfered portion 503a may include a circular shape or a ramp surface. The chamfered portion 503a may have a curvature of 1 mm (1R) to 4 mm (4R), but the embodiments of the present disclosure are not limited thereto. For example, the curvature of the chamfered portion 503a may vary based on the length L of the latch member 503.

[0450] According to another embodiment of the present disclosure, since the coupling portion 500 is configured to have a circular shape or a ramp surface, a sound device 30 in which sound characteristics and / or sound pressure level characteristics are further enhanced may be provided.

[0451] According to another embodiment of the present disclosure, the sound characteristics and / or sound pressure level characteristics of the sound output through the hollow portion 501 of the coupling portion 500 may vary based on the curvature of the chamfered portion 503a. For example, compared with the case where the chamfered portion 503a has a rectangular shape, in the case where the chamfered portion 503a has a non-rectangular shape, it can be seen that the peaks and / or dips in the low-pitched vocal bands to the high-pitched vocal bands are improved, thereby enhancing the balance characteristics of the sound pressure level or the flatness characteristics of the sound pressure level. In addition, as the curvature of the chamfered portion 503a increases, the flatness characteristics and / or sound pressure level characteristics of the sound pressure level in the high-pitched vocal bands may be further enhanced.

[0452] A sound device 30 according to another embodiment of the present disclosure may further include one or more holes 331o. For example, since at least one or more holes 331o may be disposed in Figure 23 and Figure 29at the vibration member 331 described in, and the sound device 30 may be configured to include one or more of the shape of the coupling part 500, the width W of the coupling part 500, and the length L of the coupling part 500, so that the sound characteristics and / or sound pressure level characteristics in the low-pitched vocal cords including the low-pitched sound can be further enhanced.

[0454] Referring to Figure 18 , the sound device 30 according to another embodiment of the present disclosure may include a first housing 311. For example, Figure 18 FIG. shows an embodiment of the first housing 311 in the sound device 30 in which the housing 310 is configured as described above with reference to Figure 29 described. For example, the second housing 312 may be removed (or omitted) from the housing 310 described above with reference to Figures 18 to 20 described, and thus, the housing 310 may be configured to include only the first housing 311. For example, the housing 310 may be configured to be equal to the housing 310 described above with reference to Figures 23 to 28 described. The description of the first housing 311 may be substantially the same as that of Figures 18 to 20 , and thus, the same reference numerals refer to the same elements, and repeated descriptions are omitted.

[0455] According to another embodiment of the present disclosure, the sound device 30 may include a first housing 311 and may be configured to include one or more of the shape of the coupling part 500, the width W of the coupling part 500, and the length L of the coupling part 500. The sound characteristics and / or sound pressure level characteristics of each of the low-pitched vocal cords and the mid-pitched vocal cords may be further enhanced, the sound reproduction band may be further extended, and the attachment or detachment process of the sound generation module 330 attached to the internal material 130 may be easily performed. The plate member 340 may solve the problem of the output of the low-pitched vocal cords caused by the miniaturization of the sound device 30, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords may be further enhanced.

[0456] Figures 23 to 28 FIG. shows a sound device according to another embodiment of the present disclosure. Figure 30 FIG. shows another embodiment of the connection member 380 described above with reference to Figure 29 described. Therefore, in the following description, repeated descriptions of other elements except the connection member 380 are omitted or will be briefly given below.

[0457] In the configuration Figure 29In the case of the connecting member 380, the inventors of the present disclosure have recognized that the sound characteristics and / or the sound pressure level characteristics are reduced because the edge portion (or the peripheral portion) of the connecting member 380 is not connected to or does not contact the vehicle interior material 130. For example, the inventors of the present disclosure have recognized that the loss of sound (or vibration transmission) occurs because the peripheral portion of the connecting member 380 is not connected to or does not contact the vehicle interior material 130. Therefore, the inventors of the present disclosure have recognized that the sound characteristics and / or the sound pressure level characteristics of the low-pitched vocal cords are reduced. Therefore, the inventors have performed extensive research and experiments. Based on the extensive research and experiments, the inventors of the present disclosure have invented a sound device and a vehicle device including the sound device, which can further enhance the sound characteristics and / or the sound pressure level characteristics of the low-pitched vocal cords. This will be described below.

[0458] Referring Figure 30 , according to another embodiment of the present disclosure, the sound device 30 may further include a connecting member 380.

[0459] The connecting member 380 may include a first portion and a second portion. The second portion may be the peripheral portion of the housing 310. The second portion may be the portion (or region) between the vehicle interior material 130 and the peripheral portion of the housing 310. The first portion may be other portions of the housing 310 except the peripheral portion. For example, the first portion may correspond to the central portion of the housing 310, and the central portion is surrounded by the second portion corresponding to the peripheral portion of the housing 310.

[0460] According to an embodiment of the present disclosure, the first portion of the connecting member 380 may include an opening hole 380o connected to the internal space 313 of the housing 310. For example, the first portion of the connecting member 380 may include an opening hole 380o connected to the internal space 313 of the first housing 311. According to an embodiment of the present disclosure, the housing 310 or the first housing 311 may include at least one or more regions. For example, the housing 310 or the first housing 311 may include a first region A1, a second region A2, and a third region A3.

[0461] The first region A1 may correspond to the central portion of the housing 310 or the first housing 311. The first region A1 may be at the central portion of the housing 310 or the first housing 311. The second region A2 may correspond to the peripheral portion of the housing 310 or the first housing 311 surrounding the central portion. 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 at the first region A1 and the third region A3. For example, the second portion of the connecting member 380 may be at the second region A2.

[0462] According to an embodiment of the present disclosure, the first and second portions of the connecting member 380 may have different thicknesses. For example, the connecting member 380 may include a first portion and a 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 at the first region A1 may be different from the thickness "T1+T2" of the connecting member 380 at the second region A2. At least one thickness of the connecting member 380 at each of the first region A1 and the third region A3 may be different from the thickness "T1+T2" of the connecting member 380 at the second region A2. For example, the thickness "T1+T2" of the connecting member 380 at the second region A2 may be thicker than the thickness T1 of the connecting member 380 at the first region A1.

[0463] According to an embodiment of the present disclosure, the second portion of the connecting member 380 may have a thickness "T1+T2" that is thicker than the first portion, and thus, the peripheral portion of the connecting member 380 may be connected to or in contact with the vehicle interior material 130 without being partially lifted (or disassembled). Therefore, it is possible to prevent the peripheral portion of the connecting member 380 from being partially lifted (or disassembled) from the vehicle interior material 130, and vibrations at the peripheral portion of the housing 310 can be transmitted to the vehicle interior material 130 without loss of vibrations (or vibration transmission) at the peripheral portion of the housing 310. The vibrations at the peripheral portion of the housing 310 can increase the vibration area of the vehicle interior material 130, and thus, the sound characteristics of the low-pitched vocal cords can be further improved or enhanced. Therefore, the sound generated by the vibration of the sound device 30 can be transmitted to the vehicle interior material 130 without loss, and thus, the sound of the low-pitched vocal cords can be more enhanced. For example, the sound generated by the vibration of the sound device 30 can be transmitted to the vehicle interior material 130 through the opening 310o and the peripheral portion of the housing 310, and thus, the vibration efficiency transmitted from the housing 310 to the vehicle interior material 130 can be increased, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords.

[0464] 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.

[0465] The first connecting member 381 may be at the first part and the second part. The first connecting member 381 may be connected to the housing 310. The first connecting member 381 may be connected to (or attached to) the first housing 311. The first connecting member 381 may be connected to (or attached to) the rear surface of the first housing 311. The first connecting member 381 may be connected to (or attached to) the first region to the third region A1, A2, and A3 of the housing 310. For example, the first connecting member 381 may be connected to (or attached to) the entire rear surface of the first housing 311.

[0466] According to an embodiment of the present disclosure, the first connecting member 381 may include a hole 380o that is at the first part and connected to the internal space 313 of the housing 310. For example, the first connecting member 381 may include a hole 380o that is at the first part and connected to the internal space 313 of the first housing 311.

[0467] The second connecting member 382 may be at the second part. The second connecting member 382 may be connected to a part of the first connecting member 381. The second connecting member 382 may be on the first connecting member 381 at the second part. For example, the first part may include only the first connecting member 381 among the first connecting member 381 and the second connecting member 382. The first connecting member 381 and the second connecting member 382 may be together at the second part. For example, the second part may 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 may be together at the second region A2.

[0468] The first part and the second part of the connecting member 380 may have different widths (or dimensions). In the connecting member 380, the width of the first part may be smaller than the width of the second part. For example, the width of the connecting member 380 at the first region A1 and the third region A3 may be smaller than the width of the connecting member 380 at the second region A2. Therefore, the connecting member 380 may include a first part and a second part having different sizes (or widths) and different thicknesses.

[0469] The second connecting member 382 may be at the periphery of the first connecting member 381. The second connecting member 382 may be configured to be stacked on the first connecting member 381 at the second part. For example, the second connecting member 382 may be configured to be stacked on the first connecting member 381 at the second region A2. Therefore, the thickness "T1 + T2" of the second part of the connecting member 380 may be thicker than the thickness T1 of the first part, and thus, the peripheral part of the housing 310 may be connected to (or contact) the vehicle interior material 130 without being partially lifted (or disassembled). For example, the second connecting member 382 may be a buffer member or a pad member, but the embodiments of the present disclosure are not limited thereto.

[0470] The first connecting member 381 may be substantially the same as the connecting member 380 described above with reference to Figures 21 to 28 and Figure 29 Thus, the description of the first connecting member 381 may be substantially the same as the description with reference to the above Figure 30 and Figures 21 to 28 and thus, the same reference numerals refer to the same elements, and repeated descriptions may be omitted or will be briefly given below.

[0471] The second connecting member 382 may include the same material (or substance) as that of the first connecting member 381, but the embodiments of the present disclosure are not limited thereto. For example, one of the first connecting member 381 and the second connecting member 382 may include a material with relatively high elasticity (or Young's modulus). One of the first connecting member 381 and the second connecting member 382 may be configured with a highly elastic rubber or the like, but the embodiments of the present disclosure are not limited thereto. One of the first connecting member 381 and the second connecting member 382 may have a material with relatively high elasticity (or Young's modulus), and may include a material with 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 include ethylene propylene diene rubber (or ethylene propylene diene M-class rubber), ethylene propylene rubber or polyurethane rubber. For example, the ethylene propylene rubber may be ethylene propylene diene monomer (EPDM), but the embodiments of the present disclosure are not limited thereto. For example, the hardness of EPDM may be 40 to 90, but the embodiments of the present disclosure are not limited thereto. For example, the tensile strength of EPDM may be 50 kg / cm 2 to 200 kg / cm 2 but the embodiments of the present disclosure are not limited thereto. For example, the minimum elongation rate of EPDM may be 200%, but the embodiments of the present disclosure are not limited thereto. For example, the use temperature of EPDM may be -30°C to 110°C, but the embodiments of the present disclosure are not limited thereto.

[0472] According to an embodiment of the present disclosure, the coupling member 320 may be configured with a material different from that of the connecting member 380. For example, at least one of the first connecting member 381 and the second connecting member 382 may be configured with a material having a higher elasticity (or Young's modulus) than that of the coupling member 320.

[0473] According to an embodiment of the present disclosure, the width of the connecting member 380 at the second part 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.

[0474] According to an embodiment of the present disclosure, each of the first connecting member 381 and the second connecting member 382 of the connecting member 380 may have a compressive force (or a contracting force) and an elastic restoring force, and may be contracted or compressed by the coupling between the coupling part 500 and the first housing 311. For example, the first connecting member 381 disposed (or inserted) between the first housing 311 and the vehicle interior material 130 may have a first thickness T1 obtained by being compressed by the pressure of the first housing 311. The second connecting member 382 disposed (or inserted) between the first housing 311 and the vehicle interior material 130 may have a second thickness T2 obtained by being compressed by the pressure of the first housing 311.

[0475] The first thickness T1 of the first connecting member 381 may be equal to 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 each be 0.5 mm or greater, but the embodiments of the present disclosure 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 each be 0.5 mm to 3 mm, but the embodiments of the present disclosure are not limited thereto.

[0476] The sound device 30 according to another embodiment of the present disclosure may further include an air gap AG in a region between the housing 310 and the vehicle interior material 130. For example, the air gap AG may be in a region between the vehicle interior material 130 and the first part of the connecting member 380, or in a region between the first part and the second part of the connecting member 380. For example, the air gap AG may be at a third region A3 between the first region A1 and the second region A2 of the housing 310. For example, the air gap AG may be in a region between the third region A3 of the housing 310 and the vehicle interior material 130. For example, the air gap AG may be provided at the third region A3 between the first region A1 and the second region A2 of the housing 310, and thus may minimize the separation or interference between the vibration of the first region A1 and the vibration of the second region A2, thereby increasing the vibration force (or vibration amount) transmitted from the second region A2 (e.g., the peripheral part) of the housing 310 to the vehicle interior material 130. Therefore, the frequency band (reproduction band) of the low-pitched sound band may be extended, and thus the sound characteristics and / or sound pressure level characteristics of the low-pitched sound band may be more improved.

[0477] According to an embodiment of the present disclosure, the connection member 380 including a first part and a second part having different thicknesses may be configured to provide a sound device 30 in which the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords are further enhanced. According to an embodiment of the present disclosure, since the second connection member 382 is configured, when the sound device 30 is coupled to the roof trim of the vehicle device, the vibration area (or vibration region) of the roof trim of the vehicle device may be widened, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords may be further enhanced.

[0478] Figure 31 is another embodiment according to the present disclosure Figure 31 exploded perspective view of the sound device shown.

[0479] Referring to Figure 29 and Figure 30 , according to another embodiment of the present disclosure, the first connection member 381 of the connection member 380 may be connected (or attached) to the rear surface (or the first part and the second part) of the housing 310 or the first housing 311 such that the hole 380o overlaps (or is connected to) the housing 310 or the first housing 311, and the second connection member 382 of the connection member 380 may be connected (or attached) to the peripheral portion (or the second part) of the first connection member 381.

[0480] The housing 310 or the first housing 311 may be disposed on the vehicle interior material 130 such that the opening 310o overlaps (or is connected to) the hole 135 of the vehicle interior material 130. In the interior space of the vehicle, the coupling portion 500 may be connected or coupled to the sound device 30 or the housing 310 through the hole 135 (in the arrow direction) of the vehicle interior material 130. For example, in the interior space of the vehicle, the coupling portion 500 may be connected or coupled to the sound device 30 or the housing 310 through the hole 135 of the vehicle interior material 130 and the hole 380o of the first connection member 381. For example, in the interior space of the vehicle, the coupling portion 500 may be received or inserted into the hole 135 of the vehicle interior material 130, the hole 380o of the first connection member 381, and the opening 310o of the first housing 311. For example, the hook member 504 of the coupling portion 500 may be connected or coupled to the opening 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 310o of the first housing 311 and may be connected or coupled to the groove portion 311g of the first housing 311 based on a hook coupling scheme. Accordingly, the first housing 311 may be connected (or contacted) to the vehicle interior material 130 and coupled to the coupling portion 500 through the first connection member 381 and the second connection member 382, and may vibrate the vehicle interior material 130 based on the vibration of the vibration device to output sound.

[0481] The first connecting member 381 may have an initial thickness T1' before compression (or contraction), and may be compressed (or contracted) to have a deformed thickness (or compressed 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. For example, when the coupling portion 500 is coupled (or connected) to the housing 310, based on the pressure applied from the housing 310, the thickness of the first connecting member 381 may be compressed from the initial thickness T1' to the compressed thickness T1, and thus, the vibration of the first region A1 in the first housing 311 may be efficiently transmitted to the vehicle interior material 130 through the first portion of the first connecting member 381. For example, when the sound device 30 (or the housing 310) is separated (or disassembled) from the vehicle interior material 130 by separating (or disassembling) the coupling portion 500, the first connecting member 381 may be restored from the deformed thickness (or compressed thickness) T1 to the initial thickness T1' by the elastic restoring force.

[0482] The second connecting member 382 may have an initial thickness T2' before compression (or contraction), and may be compressed (or contracted) to have a deformed thickness (or compressed thickness) T2 based on the pressure applied from the housing 310 through the coupling (or connection) between the coupling portion 500 and the housing 310. For example, when the coupling portion 500 is coupled (or connected) to the housing 310, based on the pressure applied from the housing 310, the thickness of the second connecting member 382 may be compressed from the initial thickness T2' to the compressed thickness T2, and thus, the vibration of the second region A2 at the first housing 311 may be efficiently transmitted to the vehicle interior material 130 through the first portions of the compressed (or contracted) first connecting member 381 and the second connecting member 382. For example, when the sound device 30 (or the housing 310) is separated (or disassembled) from the vehicle interior material 130 by separating (or disassembling) the coupling portion 500, the second connecting member 382 may be restored from the deformed thickness (or compressed thickness) T2 to the initial thickness T2' by the elastic restoring force.

[0483] Based on the coupling (or connection) between the coupling part 500 and the housing 310, the vehicle interior material 130 connected to (or in contact with) the housing 310 or the first housing 311 can be deformed to include a zigzag part or at least one bent part, and thus, the partial lifting (or disassembly or separation) occurring between the peripheral part of the housing 310 or the first housing 311 and the vehicle interior material 130 can be prevented by the second part of the connecting member 380 having a relatively thick thickness. Therefore, the vibration at the peripheral part of the housing 310 or the first housing 311 due to the vibration of the vibration device can be transmitted to the vehicle interior material 130 without loss of the vibration (or vibration transmission) at the peripheral part of the first housing 311, and thus, the vibration efficiency transmitted from the housing 310 to the vehicle interior material 130 can be improved, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the bass vocal cords.

[0484] According to another embodiment of the present disclosure, the connecting member 380 described above with reference to Figure 29 can be changed to a connecting member 380 including the first connecting member 381 and the second connecting member 382 described above with reference to Figure 30 and Figure 31 and thus, in the sound device 30 described above with reference to Figure 32 the sound characteristics and / or sound pressure level characteristics of each of the bass vocal cords and the midrange vocal cords can be further enhanced, and the sound reproduction frequency band can be further extended.

[0485] Figure 31 FIG. shows a sound device according to another embodiment of the present disclosure. Figure 3 1 FIG. shows another embodiment of the connecting member 380 described above with reference to Figure 32 and Figure 33 and thus, in the following description, the repeated description of other elements except the connecting member 380 is omitted or can be briefly given below. The description of the housing 310 or the first housing 311 and the description of the connecting member 380 described above with reference to Figure 34 and Figure 33 can be included in the description of Figure 35 .

[0486] Referring to Figure 33 , the sound device 30 according to another embodiment of the present disclosure may further include a connecting member 380.

[0487] The connecting member 380 may include a first portion and a second portion. The second portion may be the peripheral portion of the housing 310. The second portion may be the portion (or region) between the vehicle interior material 130 and the peripheral portion of the housing 310. The first portion may be the other portion of the housing 310 other than the peripheral portion. For example, the first portion may correspond to the central portion of the housing 310, and the central portion is surrounded by the second portion corresponding to the peripheral portion of the housing 310.

[0488] According to an embodiment of the present disclosure, the first portion of the connecting member 380 may include an opening hole 380o connected to the internal space 313 of the housing 310. For example, the first portion of the connecting member 380 may include an opening hole 380o connected to the internal space 313 of the first housing 311.

[0489] According to an embodiment of the present disclosure, the housing 310 or the first housing 311 may include at least one or more regions. For example, the housing 310 or the first housing 311 may include a first region A1, a second region A2, and a third region A3.

[0490] The first region A1 may correspond to the central portion of the housing 310 or the first housing 311. The first region A1 may be at the central portion of the housing 310 or the first housing 311. The second region A2 may correspond to the peripheral portion of the housing 310 or the first housing 311 surrounding the central portion. 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 at the first region A1. For example, the second portion of the connecting member 380 may be spaced apart from the first portion and may be at the second region A2. For example, the second portion of the connecting member 380 may be spaced apart from the first region A1 and may be at the second region A2. For example, the first portion of the connecting member 380 may be at the central portion of the housing 310. For example, the second portion of the connecting member 380 may be spaced apart from the first region A1 and may be at the peripheral portion of the housing 310.

[0491] According to an embodiment of the present disclosure, the first part and the second part of the connecting member 380 may have different thicknesses T3 and T4. For example, the connecting member 380 may include a first part and a second part having different thicknesses T3 and 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 at the first region A1 may be different from the thickness T4 of the connecting member 380 at the second region A2. For example, the thickness T4 of the connecting member 380 at the second region A2 may be thicker than the thickness T3 of the connecting member 380 at the first region A1. For example, the connecting member 380 may not be provided at the third region A3 between the first region A1 and the second region A2 or at the portion between the first part and the second part.

[0492] According to an embodiment of the present disclosure, the second part of the connecting member 380 may have a thickness T4 thicker than that of the first part, and thus, the peripheral portion of the connecting member 380 may be connected to or in contact with the vehicle interior material 130 without being partially lifted (or disassembled or separated). Accordingly, it is possible to prevent the peripheral portion of the connecting member 380 from being partially lifted (or disassembled or separated) from the vehicle interior material 130, and vibrations at the peripheral portion of the housing 310 may be transmitted to the vehicle interior material 130 without loss of vibrations (or vibration transmission) at the peripheral portion of the housing 310. Vibrations at the peripheral portion of the housing 310 may increase the vibration area of the vehicle interior material 130, and thus, the sound characteristics of the low-pitched vocal cords may be more improved or enhanced. Accordingly, the sound generated by the vibration of the sound device 30 may be transmitted to the vehicle interior material 130 without loss, and thus, the sound of the low-pitched vocal cords may be more enhanced. For example, the sound generated by the vibration of the sound device 30 may be transmitted to the vehicle interior material 130 through the opening 310o and the peripheral portion of the housing 310, and thus, the vibration efficiency transmitted from the housing 310 to the vehicle interior material 130 may be increased, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords.

[0493] According to an embodiment of the present disclosure, the connecting member 380 may include a first connecting member 383 and a second connecting member 384.

[0494] The first connecting member 383 may be connected to the housing 310. The first connecting member 383 may be at the first portion. The first connecting member 383 may be only at the first portion of the first and second portions. The first connecting member 383 may be connected to (or attached to) the first region A1 of the housing 310. For example, the first connecting member 383 may be connected to (or attached to) the rear surface of the first housing 311 corresponding to the first portion of the first and second portions. For example, the first connecting member 383 may be connected to (or attached to) the central portion (or rear central portion) of the first housing 311. For example, the first connecting member 383 may be connected to (or attached to) only the first region A1 of the first to third regions A1, A2, and A3 of the housing 310.

[0495] According to an embodiment of the present disclosure, the first connecting member 383 may include a hole 380o that is at the first portion and connected to the internal space 313 of the housing 310. For example, the first connecting member 383 may include a hole 380o that is at the first portion and connected to the internal space 313 of the first housing 311.

[0496] The second connecting member 384 may be at the second portion. The second connecting member 384 may be only at the second portion of the first and second portions and may be spaced apart from the first connecting member 383. The second connecting member 384 may surround the first connecting member 383 at the second portion of the first and second portions, where an air gap AG is between the second connecting member 384 and the first connecting member 383. The second connecting member 384 may be connected to (or attached to) the second region A2 of the housing 310. For example, the second connecting member 384 may be connected to (or attached to) the rear surface of the first housing 311 corresponding to the second portion of the first and second portions. For example, the second connecting member 384 may be connected to (or attached to) the peripheral portion (or rear peripheral portion) of the first housing 311. For example, the second connecting member 384 may be connected to (or attached to) only the second region A2 of the first to third regions A1, A2, and A3 of the housing 310. The first and second portions of the connecting member 380 may have different widths (or dimensions). The width of the first portion may be less than the width of the second portion. For example, the width of the first connecting member 383 at the first region A1 may be less than the width of the second connecting member 384 at 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.

[0497] Each of the first connecting member 383 and the second connecting member 384 may be a buffer member or a pad member, but embodiments of the present disclosure are not limited thereto.

[0498] The first connecting member 383 may include the same material as that of the second connecting member 384. Each of the first connecting member 383 and the second connecting member 384 may be highly elastic rubber or the like, but embodiments of the present disclosure 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 may include ethylene propylene diene rubber (or ethylene propylene diene M-class rubber), ethylene propylene rubber, or polyurethane rubber.

[0499] According to an embodiment of the present disclosure, the width of the connecting member 380 at the second portion may be greater than the width of the coupling member 320. For example, the width of the connecting member 380 at the second portion may be greater than the width of the coupling member 320.

[0500] According to an embodiment of the present disclosure, each of the first connecting member 383 and the second connecting member 384 of the connecting member 380 may have a compressive force (or a contraction force) and an elastic restoring force, and may be contracted or compressed by the coupling between the coupling portion 500 and the first housing 311. For example, the first connecting member 383 disposed (or inserted) between the first housing 311 and the vehicle interior material 130 may have a first thickness (or a third thickness) T3 obtained by the compression of the pressure of the first housing 311. The second connecting member 384 disposed (or inserted) between the first housing 311 and the vehicle interior material 130 may have a second thickness (or a fourth thickness) T4 obtained by the compression of the pressure of the first housing 311.

[0501] The first thickness T3 of the first connecting member 383 may be different from the second thickness T4 of the second connecting member 382. Each of 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 greater, but embodiments of the present disclosure are not limited thereto. For example, each of 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, but embodiments of the present disclosure are 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 within the range of 0.5 mm to 3 mm. For example, within the range of 0.5 mm to 3 mm, the second thickness T4 of the second connecting member 384 may be thicker than the first thickness T3 of the first connecting member 383.

[0502] The sound device 30 according to another embodiment of the present disclosure may further include an air gap AG. For example, the air gap AG may be in the region between the vehicle interior material 130 and the first portion of the connecting member 380, or in the region between the first portion and the second portion of the connecting member 380. For example, the air gap AG may be in the third region A3 between the first region A1 and the second region A2 of the housing 310. For example, the air gap AG may be in the region between the second region A2 of the housing 310 and the vehicle interior material 130. For example, the air gap AG may be provided in the third region A3 between the first region A1 and the second region A2 of the housing 310, and thus may minimize the separation or interference between the vibrations of the first region A1 and the vibrations of the second region A2, thereby increasing the vibration force (or the amount of vibration) transmitted from the second region A2 (e.g., the peripheral portion) of the housing 310 to the vehicle interior material 130. Accordingly, the frequency band (reproduction band) of the low-pitched sound band may be extended, and thus the sound characteristics and / or the sound pressure level characteristics of the low-pitched sound band may be more improved.

[0503] Figures 33 to 35 is according to another embodiment of the present disclosure Figures 3 to 31 exploded perspective view of the sound device shown.

[0504] Refer to Figure 36 and Figure 34 According to an embodiment of the present disclosure, the first connecting member 383 of the connecting member 380 may be connected (or attached) to the central portion (or the first portion) of the housing 310 or the first housing 311 such that the hole 380o overlaps (or is connected to) the housing 310 or the first housing 311, and the second connecting member 384 of the connecting member 380 may be connected (or attached) to the peripheral portion (or the second portion) of the housing 310 or the first housing 311.

[0505] The housing 310 or the first housing 311 may be disposed on the vehicle interior material 130 such that the opening 310o overlaps (or is connected to) the hole 135 of the vehicle interior material 130. In the inner space of the vehicle, the coupling part 500 may be connected or coupled to the sound device 30 or the housing 310 through the hole 135 of the vehicle interior material 130 (in the arrow direction). For example, in the inner space of the vehicle, the coupling part 500 may be connected or coupled to the sound device 30 or the housing 310 through the hole 135 of the vehicle interior material 130 and the hole 380o of the first connecting member 383. For example, in the inner space of the vehicle, the coupling part 500 may be received 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 housing 311. For example, the hook member 504 of the coupling part 500 may be connected or coupled to the opening 310o of the first housing 311. For example, the hook member 504 of the coupling part 500 may be inserted (or received) into the opening 310o of the first housing 311 and may be connected or coupled to the groove portion 311g of the first housing 311 based on a hook coupling scheme. Accordingly, the first housing 311 may be connected (or contacted) to the interior material 130 through the first connecting member 383 and the second connecting member 384 and may be coupled to the coupling part 500, and may vibrate the vehicle interior material 130 based on the vibration of the vibration device to output sound.

[0506] The first connecting member 383 may have an initial thickness T3' before being compressed (or contracted) and may be compressed (or contracted) to have a deformed thickness (or compressed thickness) T3 based on the pressure applied from the housing 310 through the coupling (or connection) between the coupling part 500 and the housing 310. For example, when the coupling part 500 is coupled (or connected) to the housing 310, based on the pressure applied from the housing 310, the thickness of the first connecting member 383 may be compressed from the initial thickness T3' to the compressed thickness T3, and thus, the vibration of the first area A1 at the first housing 311 may be efficiently transmitted to the vehicle interior material 130 through the first connecting member 381. For example, when the sound device 30 (or the housing 310) is separated (or disassembled) from the vehicle interior material 130 by separating (or disassembling) the coupling part 500, the first connecting member 383 may be restored from the deformed thickness T3 to the initial thickness T3' by an elastic restoring force.

[0507] The second connecting member 384 may have an initial thickness T4' before compression (or contraction), and may be compressed (or contracted) to have a deformed thickness (or compressed thickness) T4 based on the pressure applied from the housing 310 through the coupling portion 500 (or connection) between the coupling portion 500 and the housing 310. For example, when the coupling portion 500 is coupled (or connected) to the housing 310, based on the pressure applied from the housing 310, the thickness of the second connecting member 384 may be compressed from the initial thickness T4' to the compressed thickness T4, and thus, the vibration of the second region A2 at the first housing 311 may be efficiently transmitted to the internal material 130 through the compressed (or contracted) second connecting member 384. For example, when the housing 310 (or the sound device 30) is separated (or disassembled) from the vehicle interior material 130 by separating (or disassembling) the coupling portion 500, the second connecting member 384 may be restored from the deformed thickness T4 to the initial thickness T4' by the elastic restoring force.

[0508] Based on the coupling (or connection) between the coupling portion 500 and the housing 310, the vehicle interior material 130 connected to (or in contact with) the housing 310 or the first housing 311 may be deformed to include a zigzag portion or at least one bent portion, and thus, the partial lifting (or disassembly or separation) occurring between the peripheral portion of the housing 310 or the first housing 311 and the vehicle interior material 130 may be prevented by the second connecting member 384 having a relatively thick thickness. Therefore, the vibration at the peripheral portion of the housing 310 or the first housing 311 based on the vibration of the sound generation module 330 may be transmitted to the vehicle interior material 130 without loss of the vibration (or vibration transmission) at the peripheral portion of the first housing 311, and thus, the vibration efficiency transmitted from the housing 310 to the vehicle interior material 130 may be improved, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the bass vocal cords.

[0509] Figure 36 A vibration device according to an embodiment of the present disclosure is shown. Figures 33 to 35 is a cross-sectional view taken along Figure 33 the line I-I' shown in Figure 36 is a cross-sectional view taken along Figures 32 to 34 the line II-II' shown in

[0510] Referring to Figure 37 , the sound generation module 330 according to an embodiment of the present disclosure may include vibration devices 333 and 335. The vibration devices 333 and 335 may include one or more vibration generators 1310.

[0511] The vibration generator 1310 may include a piezoelectric material having piezoelectric properties. The vibration generator 1310 may vibrate (or displace or drive) a vibration member (or an interior material of a vehicle) based on the vibration (or displacement or drive) of the piezoelectric material based on an electrical signal (or voice signal or sound signal) applied to the piezoelectric material. For example, the vibration generator 1310 may alternately repeat contraction and / or expansion through the piezoelectric effect (or piezoelectric property) to perform vibration (or displacement or drive). For example, when contraction and / or expansion are alternately repeated through the inverse piezoelectric effect, the vibration generator 1310 may vibrate (or displace or drive) in the vertical direction (or thickness direction) Z. For example, in the vibration generator 1310, a piezoelectric material including piezoelectric ceramics may vibrate or mechanically displace (or vibrate or drive) in response to an electrical signal applied from the outside.

[0512] The vibration generator 1310 may be configured with a ceramic-based piezoelectric material capable of achieving relatively strong vibration, or may be configured with a piezoelectric ceramic having a perovskite-based crystal structure. For example, the vibration generator 1310 may be a vibration generating device, a vibration film, a vibration generating film, a vibrator, an active vibrator, an active vibration generator, an actuator, an exciter, a film actuator, a film exciter, an ultrasonic actuator, or an active vibration member, etc., but the embodiments of the present disclosure are not limited thereto.

[0513] The vibration generator 1310 according to an embodiment of the present disclosure may include a vibration generating unit 1311.

[0514] The vibration generating unit 1311 may be configured to vibrate through the piezoelectric effect based on a drive signal. For example, the vibration generating unit 1311 may include a piezoelectric type vibration unit. The vibration generating unit 1311 may include at least one or more of a piezoelectric inorganic material and a piezoelectric organic material. For example, the vibration generating unit 1311 may be a vibration device, a piezoelectric device, a piezoelectric device unit, a piezoelectric device layer, a piezoelectric structure, a piezoelectric vibration unit, or a piezoelectric vibration layer, etc., but the embodiments of the present disclosure are not limited thereto.

[0515] The vibration generating unit 1311 according to an embodiment of the present disclosure may include a vibration unit 1311a, a first electrode unit 1311b, and a second electrode unit 1311c.

[0516] The vibration unit 1311a may include a piezoelectric material or an electroactive material including a piezoelectric effect. For example, a piezoelectric material may have such a property that when a pressure or distortion phenomenon is applied to a crystal structure by an external force, a potential difference appears due to dielectric polarization caused by a change in the relative positions of positive (+) and negative (-) ions, and thus vibration is generated by an electric field based on a reverse voltage applied thereto. For example, the vibration unit 1311a may be a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a piezoelectric composite layer, a piezoelectric composite, or a piezoelectric ceramic composite, etc., but embodiments of the present disclosure are not limited thereto.

[0517] The vibration unit 1311a may be configured as a ceramic-based material capable of achieving relatively strong vibration, or may be configured as a piezoelectric ceramic having a perovskite-based crystal structure. The perovskite-based crystal structure may have a piezoelectric effect and / or a reverse piezoelectric effect, and may be a plate-shaped structure having an orientation or alignment. The perovskite-based crystal structure may be represented by the chemical formula "ABO 3 ". In the chemical formula, "A" may include a divalent metal element, and "B" may include a tetravalent metal element. As an embodiment of the present disclosure, in the chemical formula "ABO 3 ", "A" and "B" may be cations, and "O" may be an anion. For example, the vibration unit 1311a may include at least one or more of lead titanate (PbTiO 3 ), lead zirconate (PbZrO 3 ), lead zirconate titanate (PbZrTiO 3 ), barium titanate (BaTiO 3 ), and strontium titanate (SrTiO 3 ), but embodiments of the present disclosure are not limited thereto.

[0518] The piezoelectric ceramic may be configured as a single-crystal ceramic having a crystal structure, or may be configured as a ceramic material or polycrystalline ceramic having a polycrystalline structur...
