A space may be set between the sound device 30 and the shell, and the sound (or sound pressure level) may be output based on the vibration of the air between the sound device 30 and the shell by the vehicle interior material 130. However, there may be a problem that the sound of the low-pitched vocal band is not output, and there may be a problem that the flatness of the sound pressure level is reduced, because the number of peaks and dips that appear in the reproduction frequency band of the sound (or sound pressure level) generated based on the vibration of the vehicle interior material 130 increases, and each of the highest sound pressure level and the lowest sound pressure level that appear in the reproduction frequency band of the sound (or sound pressure level) generated based on the vibration of the vehicle interior material 130 increases. A peak may be a phenomenon in which the sound pressure level bounces at a specific frequency, and a dip may be a phenomenon in which a low sound pressure level is generated as the occurrence of a sound with a specific frequency decreases. The flatness of the sound characteristic may be a deviation level between the highest sound pressure and the lowest sound pressure in a specific frequency.

[0115] The inventors of the present disclosure have performed extensive research and experiments for realizing a sound device and a vehicle device including the sound device, in which the sound characteristics of a low-pitched vocal band can be improved and the flatness characteristics of the sound pressure level can be enhanced. 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 output sounds including a high-pitched vocal band to a low-pitched vocal band, and can enhance the balance characteristics of the sound pressure level or the flatness characteristics of the sound pressure level.

For example, the coupling member 320 may include a material having elasticity for vibration absorption (or shock absorption). The coupling member 320 according to an embodiment of the present disclosure may be configured with a silicone material, a polyurethane material, or a polyolefin material, but the embodiments of the present disclosure are not limited thereto. For example, the coupling member 320 may include one or more of an adhesive, a double-sided tape, a double-sided tape, a double-sided adhesive tape, a double-sided foam tape, a double-sided adhesive foam tape, a double-sided pad, a double-sided foam pad, a double-sided adhesive foam pad, and a double-sided buffer tape, but the embodiments of the present disclosure are not limited thereto.

[0170] The sound device 30 or the housing 310 according to the embodiment of the present disclosure may further include an opening portion 310 o .

[0171] The opening portion 310o may be configured at the first housing 311 to overlap with the sound generating module 330 relative to the thickness direction Z (or vertical direction) of the sound device 30. The opening portion 310o may be configured to pass through (or vertically pass through) the first housing 311 along the thickness direction Z (or vertical direction) of the housing 310. For example, the opening portion 310o may face or directly face the first surface of the sound generating module 330. The opening portion 310o may be connected to the internal space 313 (or communicate with the internal space 313). For example, the opening portion 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 portion 310o. For example, the internal space 313 of the housing 310 may include a first space 313a connected to the opening portion 310o.

[0172] The opening 310o may be configured to reduce the air pressure of the internal space 313 of the housing 310. The opening 310o may be configured to reduce the air pressure of the first space 313a of the first housing 311 or the air pressure of the first space 313a disposed between the vibration member 331 and the first housing 311. Therefore, the frequency band of the low-pitched vocal band can be expanded, and thus the sound characteristics of the low-pitched vocal band can be improved. For example, since the pressure (or air pressure) of the first space 313a is reduced by the opening 310o, the displacement (or bending force) of the vibration member 331 disposed between the vibration member 331 and the first housing 311 can be increased, and thus, the frequency band of the low-pitched vocal band can be expanded, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band. Therefore, the sound (or sound pressure level) of the low-pitched vocal band generated based on the vibration (or displacement) of the vibration device 337 can be improved.

[0173] According to an embodiment of the present disclosure, the opening portion 310o may be arranged to correspond to the central portion of the sound generating module 330. For example, the opening portion 310o may be arranged to correspond to the central portion of the vibration device 337. For example, the opening portion 310o may include a line shape passing through the central portion of the vibration device 337, or may include a rectangular shape. For example, the opening portion 310o may be a hole, a slot, or a slit, but embodiments of the present disclosure are not limited thereto. For example, the opening portion 310o may be a sound discharge portion, a first sound discharge port, a sound output portion, a sound output port, a sound output hole, a duct hole, or a vent, but embodiments of the present disclosure are not limited thereto.

[0174] The opening portion 310o may be a space in which the sound (or sound wave) generated in the internal space 313 of the housing 310 based on the vibration of the sound generating module 330 is output to the external space (e.g., the inner space of the vehicle) of the housing 310. For example, the vibration or sound generated by the vibration (or displacement) of the vibration member 331 based on the vibration of the vibration device 337 may be output (or discharged) into the inner space of the vehicle through the opening portion 310o.

[0175] The first shell 311 of the shell 310 may also include a sloped surface (or inclined surface) 311s. The sloped surface 311s may be configured to be inclined between the opening 310o and the inner surface 311i of the first shell 311. The sloped surface 311s may be configured to guide the sound generated based on the vibration of the sound generating module 330 to the inner space of the vehicle. Therefore, the sound generated based on the vibration of the sound generating module 330 can be output to the inner space of the vehicle, and the sound characteristics and / or sound pressure level characteristics of the sound including the low-pitched vocal band can be further enhanced. For example, the inclined surface 311s may be a guide surface or a sound guiding surface, but the embodiments of the present disclosure are not limited thereto.

[0176] According to another embodiment of the present disclosure, the vibration or sound generated by the vibration of the vibration member 331 based on the vibration of the vibration device 337 can be transmitted (or output or discharged) to the vehicle interior material through the opening portion 310o, and the vehicle interior material can vibrate based on the vibration or sound transmitted through the opening portion 310o to output the sound to the inner space of the vehicle. Therefore, the sound can be generated based on the vibration of the vehicle interior material having a size larger than that of the sound device 30, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the tone vocal band including the low-tone vocal band generated based on the driving (or vibration) of the sound device 30.

[0177] Figure 5 According to the embodiments of the present disclosure Figure 3 and Figure 4 A cross-sectional view of a vibration device of a sound generating module is shown.

[0178] Reference Figures 3 to 5 , the vibration device 337 according to the embodiment of the present disclosure may include a base frame 337a, a magnetic circuit portion including a bobbin 337b, and a damper 337e. For example, the vibration device 337 may include a base frame 337a, a bobbin 337b, a magnet 337c, a coil 337d, and a damper 337e.

[0179] The base frame 337a may be the main body of the vibration device 337. The base frame 337a may support the magnet 337c. The base frame 337a may include a metal material having magnetism similar to iron (Fe). The base frame 337a may be referred to as a base plate, a lower plate, a yoke, etc., but the embodiments of the present disclosure are not limited thereto.

[0180] The base frame 337a may include a groove portion accommodating the magnet 337c and the bobbin 337b. The groove portion may be concavely formed from the upper surface of the base plate 337a to have a shape corresponding to the shape of each of the magnet 337c and the bobbin 337b.

[0181] The magnetic circuit portion may be disposed at the base frame 337a and may be configured to vibrate (or displace) the vibration member 331. For example, the magnetic circuit portion may include a magnet 337c, a bobbin 337b, and a coil 337d disposed at the base frame 337a. For example, the magnetic circuit portion may be a magnetic vibration portion or a magnetic vibration unit, but the embodiments of the present disclosure are not limited thereto.

[0182] The magnetic circuit portion according to an embodiment of the present disclosure may have an external magnetic type structure or a dynamic magnetic type structure in which the magnet 337c is arranged outward from the coil 337d (or the bobbin 337b), or may have an internal magnetic type structure or a microstructure in which the magnet 337c is arranged inward from the coil 337d (or the bobbin 337b). The vibration device 337 including the magnetic circuit portion having the internal magnetic type structure may have an overall small size and low leakage magnetic flux. The vibration device 337 according to an embodiment of the present disclosure may have an external magnetic type structure or an internal magnetic type structure, and hereinafter, an example in which the vibration device 337 has an internal magnetic type will be described.

[0183] The magnet 337c may be received or inserted into a groove portion of the base frame 337a. The magnet 337c may be a permanent magnet that can be received or inserted into the bobbin 337b.

[0184] The bobbin 337b may be provided on the base frame 337a to surround the magnet 337c. For example, the bobbin 337b may include a structure formed of a material obtained by processing pulp or paper, Al or magnesium (Mg) or an alloy thereof, or a synthetic resin such as polyimide, etc. For example, the bobbin 337b may be implemented with a polyimide film having relatively good heat dissipation characteristics and being relatively light in weight.

[0185] The wire barrel 337b may be a circular shape or an oval shape, but the embodiments of the present disclosure are not limited thereto. For example, the oval shape of the wire barrel 337b may have an elliptical shape, a rectangular shape with rounded corners, or a non-circular curved shape whose width is different from its height, but the embodiments of the present disclosure are not limited thereto. For example, the wire barrel 337b having an oval shape may improve the sound of a high-pitched vocal cord compared to the wire barrel 337b having a circular shape, and may reduce the generation of heat caused by vibration, and therefore, may have excellent heat dissipation characteristics.

[0186] The wire barrel 337b may be connected (or coupled) to the vibration member 331 by an adhesive member 338. For example, the front surface (or front end portion) of the wire barrel 337b may be attached to the second surface 331s2 of the vibration member 331 by an adhesive member 338. For example, when the sound device 30 includes a heat sink 339 attached to the second surface 331s2 of the vibration member 331, the wire barrel 337b may be connected to the heat sink 339 by an adhesive member 338.

[0187] The coil 337d can be wound around the outer circumferential surface of the bobbin 337b, and can be supplied with a sound generating current (or voice current) from the outside. The coil 337d can drop or rise together with the bobbin 337b. The coil 337d can be called a voice coil. When current is applied to the coil 337d, the entire part of the bobbin 337b can be moved up and down according to Fleming's left-hand rule based on the applied magnetic field generated around the coil 337d and the external magnetic field generated around the magnet 337c, and sound (or sound waves) or vibration can be generated by the vibration of the vibration member 331 based on the vertical movement (or vibration) of the bobbin 337b.

[0188] The damper 337e may be connected between the base frame 337a and the bobbin 337b. For example, the damper 337e may be a tripod, a suspension, an edge, etc., but the embodiments of the present disclosure are not limited thereto.

[0189] According to an embodiment of the present disclosure, one end (or one side) of the damper 337e can be connected to the base frame 337a, and the other end (or the other side) of the damper 337e can be connected to the outer surface of the bobbin 337b. The damper 337e can have a pleated structure between one end and the other end (or the other side), and can shrink and relax based on the vertical movement (or vertical movement) of the bobbin 337b to control the vibration of the bobbin 337b. The damper 337e can utilize the restoring force to limit the vibration distance of the bobbin 337b. For example, when the bobbin 337b vibrates a certain distance or a greater distance or vibrates a certain distance or a smaller distance, the bobbin 337b can be restored to the initial position by the restoring force of the damper 337e.

[0190] The vibration device 337 according to an embodiment of the present disclosure may further include a center pole 337f and an edge frame 337g.

[0191] The center rod 337f can be accommodated or inserted into the wire barrel 337b, and can be configured to guide the rise or fall of the wire barrel 337b. For example, since the center rod 337f can be accommodated or inserted into the wire barrel 337b, the outer circumferential surface of the center rod 337f can be surrounded by the wire barrel 337b. For example, the center rod 337f can be a lifting guide or a rod sheet, etc., but the embodiments of the present disclosure are not limited thereto.

[0192] The edge frame 337g can be arranged at the front edge (or front periphery) of the base frame 337a. The edge frame 337g can be configured to support one end of the damper 337e. For example, the damper 337e can be connected between the edge frame 337g and the bobbin 337b. The edge frame 337g according to an embodiment of the present disclosure can be arranged at the front edge of the base frame 337a to have a certain height and a shape identical to the shape of the bobbin 337b. The edge frame 337g according to another embodiment of the present disclosure can be arranged at the front edge of the base frame 337a to have a certain height, and can include a hollow portion of a shape identical to the shape of the bobbin 337b.

[0193] According to an embodiment of the present disclosure, in the vibration device 337, at least a portion of the base frame 337a may be fixed (or supported) or connected (or coupled) to the second housing 312 (or the second plate 312a of the second housing 312) of the housing 310 by a fixing member 336. As an embodiment, the fixing member 336 may include an adhesive member disposed (or inserted) between at least a portion of the base frame 337a and the second housing 312 (or the second plate 312a of the second housing 312) of the housing 310. As another embodiment, the fixing member 336 may include a plurality of screws that pass through at least a portion of the base frame 337a and are fastened to the second housing 312 (or the second plate 312a of the second housing 312) of the housing 310.

[0194] The sound device 30 or the vibration device 337 according to an embodiment of the present disclosure may further include an extension portion 337i.

[0195] The extension portion 337i may extend (or protrude) from the side surface of the base frame 337a and may be fixed (or supported) or connected (or coupled) to the second housing 312 of the housing 310 or the second plate 312a of the second housing 312 by the fixing member 336 .

[0196] According to an embodiment of the present disclosure, when the fixing member 336 is an adhesive member (or a second adhesive member), the adhesive member may be disposed or connected between the extension portion 337i of the vibration device 337 and the second housing 312 (or the second plate 312a of the second housing 312). Therefore, the vibration device 337 may be fixed (or supported) or connected (or coupled) to the second housing 312 or the second plate 312a of the second housing 312 by the adhesive member.

[0197] According to another embodiment of the present disclosure, when the fixing member 336 is a plurality of screws (or a plurality of bolts), the plurality of screws may pass through the extension portion 337i of the vibration device 337 and may be fastened to the second housing 312 (or the second plate 312a of the second housing 312). Therefore, the vibration device 337 may be fixed (or supported) or connected (or coupled) to the second housing 312 or the second plate 312a of the second housing 312 by the plurality of screws.

[0198] According to another embodiment of the present disclosure, since the vibration device 337 is disposed (or inserted) between the vibration member 331 and the second housing 312 (or the second plate 312a of the second housing 312), the vibration device 337 should have a relatively thin thickness to thinly reduce the thickness of the sound device 30 or make the sound device 30 thinner, and due to this, when the height (or thickness) of the bobbin 337b is reduced, the sound pressure level can be reduced. Therefore, in order to solve the problem of reduced sound pressure level due to the height reduction of the bobbin 337b, the inventor has designed a structure in which the area of ​​the damper 337e disposed around the bobbin 337b is large. When the area of ​​the damper 337e increases, the inventor has recognized that the space where the wire for applying current to the coil 337c is provided is narrowed, thereby causing interference between the wire and the damper 337e. Therefore, through various experiments, the inventor of the present disclosure has configured a damper 337e formed by a conductor and performing a wire function.

[0199] The damper 337e according to another embodiment of the present disclosure may include a metal material electrically connected to the coil 337c. For example, the damper 337e may be configured with a metal material such as stainless steel or copper (Cu), but the embodiments of the present disclosure are not limited thereto.

[0200] The sound device 30 or the vibration device 337 according to the embodiment of the present disclosure may further include a protection member 337h.

[0201] The protective member 337h may be configured to protect the wire drum 337b from impact or to prevent deformation of the wire drum 337b caused by impact. The protective member 337h may be configured to protect the wire drum 337b and transmit the vibration of the wire drum 337b to the vibration member 331. The protective member 337h may vibrate together with the wire drum 337b. The protective member 337h may be arranged (or inserted) between the vibration member 331 and the wire drum 337b. The protective member 337h may be arranged on the front surface (or front end portion) of the wire drum 337b to protect the front surface (or front end portion) of the wire drum 337b. The protective member 337h may transmit the rise or fall (or vibration) of the wire drum 337b to the vibration member 331. The protective member 337h according to an embodiment of the present disclosure may have a ring shape connected to (attached to) the front surface of the wire barrel 337b, a circular plate shape (or a disc shape) covering the entire front surface of the wire barrel 513b2, or a cap shape surrounding the front surface and the upper outer surface of the wire barrel 337b. For example, the protective member 337h may be a wire barrel protective member, an intermediate member, or a wire barrel ring, but the embodiments of the present disclosure are not limited thereto.

[0202] The protection member 337h may be connected (or coupled) to the vibration member 331 through an adhesive member 338. For example, the protection member 337h may be attached to the second surface 331s2 of the vibration member 331 through the adhesive member 338. For example, when the sound device 30 includes a heat sink 339 attached to the second surface 331s2 of the vibration member 331, the protection member 337h may be connected to the heat sink 339 through the adhesive member 338.

[0203] According to an embodiment of the present disclosure, the vibration width (or displacement width or drive width) of the coil-type based vibration device 337 may be relatively greater than the vibration width (or displacement width or drive width) of the piezoelectric-type based vibration device, and therefore, the coil-type based vibration device 337 may enhance the sound characteristics and / or sound pressure level characteristics of the tonal vocal cords including the low-pitched vocal cords generated based on the vibration of the vibration member 331. Therefore, the sound device 30 according to an embodiment of the present disclosure may vibrate the vibration member 331 to output sound based on the vibration of the coil-type vibration device 337 whose sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords are relatively better than those of the piezoelectric-type vibration device, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the tonal vocal cords including the low-pitched vocal cords.

[0204] Figure 6 A sound device according to another embodiment of the present disclosure is shown. Figure 7 According to the embodiments of the present disclosure Figure 6 An exploded perspective view of the sound device shown.

[0205] Reference Figure 6 and Figure 7 , a sound device 30 according to another embodiment of the present disclosure may include a housing 310, a sound generating module 330, and a coupling member 320. The description of the housing 310, the sound generating module 330, and the coupling member 320 may be the same as Figures 3 to 5 The descriptions of the present invention are substantially the same, and thus, the same reference numerals refer to the same elements, and repeated descriptions are omitted or will be briefly given below.

[0206] The sound device 30 or the housing 310 according to another embodiment of the present disclosure may further include a heat dissipation portion 340 .

[0207] The heat dissipation portion 340 may be configured to dissipate heat generated by the driving (or vibration) of the sound generating module 330 to the outside. For example, the heat dissipation portion 340 may be configured to dissipate heat generated by the driving (or vibration) of the vibration device 337 in the sound generating module 330 to the outside of the housing 310.

[0208] The heat dissipation portion 340 according to an embodiment of the present disclosure may be configured to pass through a portion of the housing 310 overlapping with the vibration device 337. The heat dissipation portion 340 may be configured to pass through a portion of the second housing 312 of the housing 310 connected to and overlapping with the vibration device 337. For example, the heat dissipation portion 340 may be configured to vertically pass through a portion of the second plate 312b of the second housing 312 connected to and overlapping with the vibration device 337. For example, the heat dissipation portion 340 may include one or more holes 341.

[0209] One or more holes (or heat dissipation holes) 341 may be configured to pass through a portion of the second plate 312b of the second housing 312 that overlaps with or faces the base frame 337a of the vibration device 337. The one or more holes 341 may be configured to expose at least a portion of the base frame 337a of the vibration device 337 at the external space of the housing 310. For example, at least a portion of the rear surface of the base frame 337a of the vibration device 337 may be directly exposed to the external space of the housing 310 through the one or more holes 341 of the heat dissipation portion 340.

[0210] The one or more holes 341 may include any one of a circular shape, an oval shape, and a slit shape, but the embodiments of the present disclosure are not limited thereto. The size (or area) of the heat dissipation portion 340 including the one or more holes 341 may be smaller than the size (or area) of the vibration device 337, but the embodiments of the present disclosure are not limited thereto. For example, the total size (or area) of the heat dissipation portion 340 including the one or more holes 341 may be smaller than the size (or area) of the bobbin 337b of the vibration device 337.

[0211] According to an embodiment of the present disclosure, the heat generated based on the driving (or vibration) of the vibration device 337 can be dissipated to the external space of the shell 310 through one or more holes 341, thereby preventing the performance of the vibration device 337 from being reduced due to the heat generated when the vibration device 337 is driven (or vibrated).

[0212] Figure 8 A sound device according to another embodiment of the present disclosure is shown. Fig. 9 According to the embodiments of the present disclosure Figure 8 An exploded perspective view of the sound device shown.

[0213] Reference Figure 8 and Fig. 9 , a sound device 30 according to another embodiment of the present disclosure may include a housing 310, a sound generating module 330, and a coupling member 320. The description of the housing 310, the sound generating module 330, and the coupling member 320 may be the same as Figures 3 to 5 The descriptions of the present invention are substantially the same, and thus, the same reference numerals refer to the same elements, and repeated descriptions are omitted or will be briefly given below.

[0214] The sound device 30 according to another embodiment of the present disclosure may further include a heat dissipation portion 340 .

[0215] The heat dissipation portion 340 according to another embodiment of the present disclosure may be spaced apart from the vibration device 337, and may be configured to pass through a portion of the housing 310 facing the vibration member 331. For example, the heat dissipation portion 340 may be configured to pass through a portion of the second housing 312 of the housing 310 facing the vibration member 331 at the periphery of the vibration device 337. For example, the heat dissipation portion 340 may be configured to vertically pass through a portion of the second plate 312b of the second housing 312 facing the vibration member 331 at the periphery of the vibration device 337. For example, the heat dissipation portion 340 may include one or more first holes 343 and one or more second holes 345.

[0216] One or more first holes (or first heat dissipation holes) 343 and one or more second holes (or second heat dissipation holes) 345 may be formed (or arranged) in parallel, wherein the vibration device 337 is between the one or more first holes 343 and the one or more second holes 345. For example, the one or more first holes 343 may be formed (or arranged) at an area between the second housing 312 and a first side surface of the vibration device 337. The one or more second holes 345 may be formed (or arranged) at an area between the second housing 312 and a second side surface of the vibration device 337 opposite to the first side surface. For example, the heat dissipation portion 340 may include a pair of holes (or a pair of heat dissipation holes) 343 and 345 parallel to each other, wherein the vibration device 337 is between the pair of holes 343 and 345 parallel to each other.

[0217] One or more first holes 343 and one or more second holes 345 may be configured to vertically penetrate a portion of the vibration member 331 at the periphery of the second plate 312b of the second shell 312 facing the vibration device 337. Therefore, the second interior space 313b in the interior space 313 of the shell 310 may be connected to the exterior space of the shell 310 (or communicate with the exterior space of the shell 310) through the one or more first holes 343 and the one or more second holes 345.

[0218] The one or more first holes 343 and the one or more second holes 345 may include any one of a circular shape, an oval shape, and a slit shape, but the embodiments of the present disclosure are not limited thereto. The size (or area) of the heat dissipation portion 340 including the one or more first holes 343 and the one or more second holes 345 may be smaller than the size (or area) of the vibration device 337, but the embodiments of the present disclosure are not limited thereto. For example, the total size (or area) of the heat dissipation portion 340 including the one or more first holes 343 and the one or more second holes 345 may be smaller than the size (or area) of the bobbin 337b of the vibration device 337.

[0219] According to an embodiment of the present disclosure, the heat generated based on the driving (or vibration) of the vibration device 337 can be dissipated to the external space of the shell 310 through one or more first holes 343 and one or more second holes 345, thereby preventing the performance of the vibration device 337 from being reduced due to the heat generated when the vibration device 337 is driven (or vibrated).

[0220] According to an embodiment of the present disclosure, the heat dissipation portion 340 may be a path through which the air in the internal space 313 of the housing 310 and the heat generated in the vibration device 337 are dissipated to the external space of the housing 310. For example, in the case where a large amount of air in the internal space 313 of the housing 310 is dissipated through the heat dissipation portion 340, the sound characteristics and / or the sound pressure level characteristics of the sound device 30 may be reduced. Therefore, the one or more first holes 343 and the one or more second holes 345 of the heat dissipation portion 340 may have a size (or area) that minimizes the amount of air dissipated from the internal space 313 of the housing 310 to the external space of the housing 310 and dissipates the heat generated in the vibration device 337 and / or the heat of the internal space 313 of the housing 310 to the external space of the housing 310.

[0221] According to an embodiment of the present disclosure, the heat generated based on the driving (or vibration) of the vibration device 337 can be dissipated to the external space of the shell 310 through one or more first holes 343 and one or more second holes 345, thereby preventing the performance of the vibration device 337 from being reduced due to the heat generated when the vibration device 337 is driven (or vibrated).

Fig.15 and Fig.16 The description can be included in Fig.25 and Fig.26 in the description.

[0332] Reference Fig.25 and Fig.26 In the sound device 30 according to another embodiment of the present disclosure, the connecting member 380 may be disposed or configured between the vehicle interior material 130 and the sound generating module 330. The connecting member 380 may be configured between the first shell 311 of the shell 310 and the vehicle interior material 130. For example, the first shell 311 may include an inner surface 311i and an outer surface. The inner surface 311i of the first shell 311 may face the vibration member 331. The outer surface of the first shell 311 may be a surface of the first shell 311 opposite to the inner surface 311i. For example, the connecting member 380 may be connected to the outer surface of the first shell 311. The connecting member 380 may be a second coupling member, a third intermediate member, a third buffer member, or a third cushion member, but the embodiments of the present disclosure are not limited thereto.

[0333] The connecting member 380 may be configured with a material different from that of the coupling member 320 of the sound device 30. For example, the connecting member 380 may be configured with a material different from that of the first coupling member 321 of the coupling member 320. For example, the connecting member 380 may be configured with a material having an adhesive force different from that of the first coupling member 321. Since the connecting member 380 is configured with a material having an adhesive force different from that of the first coupling member 321, the separation or removal process (or rework) of the connecting member 380 from the vehicle interior material 130 may be easily performed in the separation or removal 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 / removing the sound device 30 from the vehicle interior material 130 may be easily performed.

[0334] The connection member 380 may be coupled (or attached) to the rear surface of the housing 310 and may contact (or surface contact) the inner 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 contact) the inner surface of the vehicle interior material 130, in 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 may be easily performed without damaging the sound device 30 or the vehicle interior material 130. For example, the inner surface of the vehicle interior material 130 may be the second surface, the outer surface (or the outdoor surface), the front surface, or the upper surface.

[0335] According to another embodiment of the present disclosure, the connecting member 380 may include a single-sided tape, a single-sided adhesive tape, a single-sided foam tape, a single-sided adhesive foam tape, a single-sided pad, a single-sided foam pad, a single-sided adhesive foam pad, a single-sided pad member, a single-sided buffer member, a single-sided buffer pad or a single-sided buffer tape, etc., but the embodiments of the present disclosure are not limited thereto. For example, the connecting member 380 may include rubber, but the embodiments of the present disclosure are not limited thereto. For example, the rubber may be ethylene propylene diene rubber (or ethylene propylene diene rubber M-grade rubber), ethylene propylene rubber or polyurethane rubber, but the embodiments of the present disclosure are not limited thereto. For example, the ethylene propylene rubber may be ethylene propylene diene monomer (EPDM), but the embodiments of the present disclosure are not limited thereto. For example, the hardness of EPDM may be 40 to 90, but the embodiments of the present disclosure are not limited thereto. For example, the tensile strength of EPDM may be 50kg / cm 2 Up to 200kg / cm 2 , but the embodiments of the present disclosure are not limited thereto. For example, the connection member 380 may include highly elastic rubber, but the embodiments of the present disclosure are not limited thereto.

[0336] According to an embodiment of the present disclosure, since the connecting member 380 includes rubber or the like, when the vibration of the shell 310 or the first shell 311 is transmitted to the vehicle interior material 130, the vibration loss can be prevented or minimized, and thus, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be further improved.

[0337] According to an embodiment of the present disclosure, the connection member 380 may further include a hole 380 o. For example, the connection member 380 may further include a hole 380 o connected to the opening portion 310 o at the housing 310 or the first housing 311.

[0338] The hole 380o may be arranged to correspond to (or overlap) the opening portion 310o. The hole 380o may have the same shape as the opening portion 310o, but the embodiments of the present disclosure are not limited thereto. For example, the hole 380o may have the same shape as the opening portion 310o, and may have a size larger than the size of the opening portion 310o. Therefore, the sound based on the vibration of the sound generating module 330 may be output to the inner space IS of the vehicle by (or through) the opening portion 310o and the hole 380o. For example, the hole 380o may be a through hole, a fourth through hole, an opening portion, an opening hole, a slit, a groove, a connecting hole, or an intermediate hole, but the embodiments of the present disclosure are not limited thereto.

[0339] According to an embodiment of the present disclosure, the hole 380o may correspond to (or overlap) the hole 137 of the vehicle interior material 130. The hole 380o may be between the hole 137 of the vehicle interior material 130 and the opening 310o of the housing 310. For example, the hole 380o may be between the hole 137 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 arranged to correspond to the opening 310o. The hole 380o of the connecting member 380 may have the same size as the size of each of the opening 310o and the hole 137, or may have a size larger than the size of each of the opening 310o and the hole 137. Therefore, the sound based on the vibration of the sound generating module 330 may be output to the inner space of the vehicle by (or through) the opening portion 310 o , the hole 380 o , and the hole 137 .

[0340] 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.

[0341] According to another embodiment of the present disclosure, the connecting member 380 may have a compressive force (or a shrinkage force) and an elastic restoring force, and may be shrunk or compressed by coupling between the coupling portion 500 and the first housing 311. The length (or thickness) of the connecting member 380 may be less than or equal to the length (or thickness) of the vehicle interior material 130. For example, the length (or thickness) of the connecting member 380 may be less than or equal to the length (or thickness) of the first housing 311.

[0342] like Fig.26 As shown, the connecting member 380 may have an initial thickness T1′ before being compressed (or contracted), and may be compressed (or contracted) to have a thickness T1′ based on the pressure applied from the housing 310 through the coupling (or connection) between the coupling portion 500 and the housing 310. Fig.25The deformed thickness (or compressed thickness) T1 shown. 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 can be compressed from the initial thickness T1' to the compressed thickness T1, and thus, the vibration of the housing 310 can be effectively transmitted to the vehicle interior material 130. For example, when the sound device 30 is separated (or disassembled) from the vehicle interior material 130 by disassembling the coupling portion 500, the connecting member 380 can be restored from the deformed thickness (or compressed thickness) T1 to the initial thickness T1' by the elastic restoring force.

[0343] The coupling portion 500 may be connected or coupled to the sound device 30 through the hole 137 of the vehicle interior material 130, the hole 380o of the connection member 380, and the opening portion 310o (arrow direction) of the first shell 311. For example, in the interior space of the vehicle, the coupling portion 500 may be connected or coupled to the opening portion 310o of the first shell 311 through the hole 137 of the vehicle interior material 130 and the hole 380o of the connection member 380. According to an embodiment of the present disclosure, at the interior space of the vehicle, the coupling portion 500 may be connected or coupled to the sound device 30 or the shell 310 through the hole 137 of the vehicle interior material 130 (arrow direction). For example, at the interior space of the vehicle, the coupling portion 500 may be accommodated or inserted into the hole 380o of the connection member 380 and the opening portion 310o of the first shell 311 through the hole 137 of the vehicle interior material 130. For example, the hook member 504 of the coupling portion 500 may be connected or coupled to the opening portion 310o of the first housing 311. For example, the hook member 504 of the coupling portion 500 may be inserted (or accommodated) into the opening portion 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.

[0344] Fig. 27 A sound device according to another embodiment of the present disclosure is shown.

[0345] Reference Fig. 27 , a vehicle interior material 130 according to another embodiment of the present disclosure may include one or more curved portions (or tortuous portions or uneven portions) 136. A connecting member 380 may be configured to correspond to the one or more curved portions 136. The connecting member 380 may be in contact with the one or more curved portions 136. The connecting member 380 may be in direct contact with the one or more curved portions 136. For example, the connecting member 380 may be in direct contact with the one or more curved portions 136 without a medium or intermediate member.

[0346] The sound device 30 or the housing 310 may be connected or coupled to one or more curved portions 136 of the vehicle interior material 130 through a connecting member 380. For example, the connecting member 380 may be provided between the housing 310 and the one or more curved portions 136 of the vehicle interior material 130. For example, the connecting member 380 may be provided between the first housing 311 and the one or more curved portions 136 of the vehicle interior material 130. For example, the first housing 311 or the first plate 311a of the first housing 311 may be connected or coupled to one or more curved portions 136 of the vehicle interior material 130 through a connecting member 380.

[0347] 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 the embodiments of the present disclosure are not limited thereto. For example, the thickness T1 of the connecting member 380 may be 0.5 mm to 3 mm, but the embodiments of the present disclosure are not limited thereto. For example, the connecting member 380 may have a thickness T1 that is reduced by the coupling force between the coupling portion 500 and the first shell 311. Fig.26 The initial thickness T1 ′ is shown to be compressed (or contracted). Therefore, based on the coupling force between the coupling portion 500 and the first housing 311 , the connection member 380 may surface-contact the vehicle interior material 130 including the one or more bent portions 136 .

[0348] According to an embodiment of the present disclosure, the sound based on the vibration of the sound generating module 330 can be output to the inner space of the vehicle by (or through) the opening portion 310o, the hole 380o, and the hole 137. In addition, the vibration of the shell 310 or the first shell 311 based on the sound (or sound pressure level or sound wave) based on the vibration of the sound generating module 330 can be effectively transmitted to the vehicle interior material 130 including one or more curved portions 136 through the connecting member 380 without vibration loss, and the vehicle interior material 130 including one or more curved portions 136 can vibrate based on the vibration of the shell 310 or the first shell 311 transmitted through the connecting member 380 to be output to the inner space of the vehicle, and therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band can be further improved.

[0349] The sound device 30 according to another embodiment of the present disclosure may include a housing 310 and a connecting member 380. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cord may be further improved, and the attachment or detachment process of the sound generating module 330 attached to the vehicle interior material 130 through the connecting member 380 including the rubber material may be easily performed.

[0350] Fig.28 A sound device according to another embodiment of the present disclosure is shown. Fig.29 The interior of a sound device according to another embodiment of the present disclosure is shown. Fig.28 and Fig.29 As shown in the above reference Figures 1 to 27 The embodiment of the sound device 30 described in the present invention additionally configures at least one hole. Therefore, in the following description, at least one hole will be described in detail, and other elements may be the same as those described above. Figures 1 to 27 The elements described above are substantially the same, and therefore, the same reference numerals refer to the same elements, and repeated descriptions are omitted or will be briefly given below. Figures 1 to 27 The description can be included in Fig.28 and Fig.29 in the description.

[0351] Reference Fig.28 and Fig.29 , the sound device 30 according to another embodiment of the present disclosure may further include one or more holes 331o.

[0352] One or more holes 331o may be configured at the vibration member 331. One or more holes 331o may be configured to pass through the vibration member 331. One or more holes 331o may be configured to pass through the vibration member 331 along the thickness direction Z of the vibration member 331. For example, one or more holes 331o may be formed to vertically pass through the vibration member 331 along the thickness direction Z of the vibration member 331.

[0353] The sound generating module 330 according to an embodiment of the present disclosure may include a vibration member 331 having one or more holes 331 o and a vibration device 337 disposed at the vibration member 331 .

[0354] One or more holes 331o may be configured to adjust the flow of air in the internal space 313 of the housing 310. For example, one or more holes 331o may perform control so 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, one or more holes 331o may be configured to adjust the flow of air between the first space 313a and the second space 313b that are spatially separated from each other by the vibration member 331 in the internal space 313 of the housing 310. For example, one or more holes 331o may be a through hole, a fifth through hole, an air hole, a vent, an airflow hole, a duct hole, a connection hole, a communication hole, or a space connection portion, but embodiments of the present disclosure are not limited thereto.

[0355] One or more holes 331 o according to an embodiment of the present disclosure may be configured in a polygonal shape, such as an oval shape, an elliptical shape, or a quadrilateral shape, but embodiments of the present disclosure are not limited thereto.

[0356] One or more holes 331o may be configured to reduce the air pressure of the internal space 313 of the housing 310. For example, one or more holes 331o may be configured to connect the first space 313a and the second space 313b separated from each other in space 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 in the housing 310 may be connected (communicated) to each other through one or more holes 331o. For example, one or more holes 331o may be configured to reduce the air pressure of the first space 313a of the first housing 311 or the first space 313a disposed between the vibration member 331 and the first housing 311. Therefore, the frequency band (reproduction frequency band) of the low-pitched vocal band can be expanded, and thus the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band can be improved. In addition, the sound generation module 330 can vibrate more stably through one or more holes 331o in the vibration member 331, and thus, the sound characteristics and / or sound pressure level characteristics can be further improved.

[0357] According to an embodiment of the present disclosure, one or more holes 331o may be disposed adjacent to the vibration device 337. For example, one or more holes 331o may be disposed at the periphery of each vibration device 337. For example, one or more holes 331o may be disposed adjacent to the side surface of the vibration device 337. For example, the distance between the one or more holes 331o and the vibration device 337 may be less than the distance between the one or more holes 331o and the side wall (or side surface) of the housing 310. For example, when the one or more holes 331o are disposed at a position away from each vibration device 337, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords may be further improved.

[0358] According to an embodiment of the present disclosure, one or more holes 331o may be configured at the vibration member 331 adjacent to the vibration device 337, wherein the vibration device 337 is between at least one or more holes 331o and the vibration member 331. For example, the vibration member 331 may include a first peripheral area adjacent to a first side surface of the vibration device 337 and a second peripheral area opposite to a second side surface of the vibration device 337 opposite to the first side surface. For example, with respect to the first direction X, the vibration member 331 may include a first peripheral area, a vibration area, and a second peripheral area. For example, in the vibration member 331, each of the first peripheral area and the second peripheral area may be a hole area or a non-arrangement area of ​​the vibration device 337, and the vibration area may be an arrangement (or setting) area of ​​the vibration device 337. For example, one or more holes 331o may be configured in each of the first peripheral area and the second peripheral area of ​​the vibration member 331 to have a symmetrical structure (or a horizontally symmetrical structure or a left-right symmetrical structure) or an asymmetrical structure (or a horizontally asymmetrical structure or a left-right asymmetrical structure) relative to the vibration device 337.

[0359] According to an embodiment of the present disclosure, the vibration device 337 may each include a long side and a short side. The distance (or separation distance or shortest distance) between the one or more holes 331o and the short side of the vibration device 337 may represent a ratio of the length of the short side of the vibration device 337. According to an embodiment of the present disclosure, the distance between the one or more holes 331o and the vibration device 337 may be 60% or less of the length of the short side of the vibration device 337.

[0360] One or more holes 331o may be provided closer to the vibration device 337 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 provided closer to the vibration device 337 than the first coupling member 321 and the second coupling member 322. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords may be enhanced.

[0361] According to an embodiment of the present disclosure, one or more holes 331o may not overlap with the opening 310o. For example, one or more holes 331o may be arranged to be spaced apart from the opening 310o. Therefore, the sound generated based on the vibration (or drive) of each vibration device 337 in the second space 313b can 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 band can be enhanced.

[0362] According to an embodiment of the present disclosure, the sound generated at the rear surface of the vibration member 331 or the second space 313b of the shell 310 based on the vibration (or drive) of each vibration device 337 can be output to the first space 313a through one or more holes 331o, and can be output (or radiated) through the opening portion 310o of the first shell 311 and the hollow portion 501 of the coupling portion 500, and therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be further enhanced.

[0363] According to another embodiment of the present disclosure, one or more holes 331o may be configured at the vibration member 331 to be aligned with the holes 331o configured above. Figure 8 and Fig. 9 For example, one or more holes 331o may be arranged at the vibration member 331 to overlap with each of one or more first holes 343 and one or more second holes 345 of the heat dissipation portion 340 arranged at the second shell 312 of the shell 310 relative to the thickness direction Z of the vibration member 331.

[0364] According to another embodiment of the present disclosure, one or more holes 331o may be disposed at the vibration member 331 so as not to interfere with the vibration member 331 disposed above. Figure 8 and Fig. 9 For example, one or more holes 331o may be arranged at the vibration member 331 so as not to overlap with each of one or more first holes 343 and one or more second holes 345 of the heat dissipation portion 340 arranged at the second shell 312 of the shell 310 relative to the thickness direction Z of the vibration member 331.

[0365] The one or more holes 331o may have a size smaller than that of the heat dissipation portion 340. For example, the one or more holes 331o may have a size smaller than that of the one or more first holes 343 and the one or more second holes 345 of the heat dissipation portion 340.

[0366] The inventors of the present disclosure have recognized that the sound characteristics change based on the structure of the coupling portion 500. Therefore, the inventors have performed various studies and experiments on the structure of the coupling portion 500. Based on the extensive studies and experiments, the inventors have invented a sound device including a coupling portion 500 for enhancing sound characteristics and / or sound pressure level characteristics and a vehicle device including the sound device. This will be described below.

[0367] Fig.30 A sound device according to another embodiment of the present disclosure is shown. Fig.31 A coupling portion according to another embodiment of the present disclosure is shown. Fig.30and Fig.31 Shown by modifying the above reference Figures 15 to 29 Therefore, in the following description, the coupling part 500 will be described in detail, and other elements may be the same as those described above. Figures 15 to 29 The elements of the description are substantially the same, and thus, the same reference numerals refer to the same elements, and repeated descriptions may be omitted or will be briefly given below.

[0368] Reference Fig.30 and Fig.31 In the sound device 30 according to another embodiment of the present disclosure, the description of the coupling portion 500 may be the same as Figures 15 to 29 The descriptions of the present invention are substantially the same, and thus, the same reference numerals refer to the same elements, and repeated descriptions are omitted or will be briefly given below.

[0369] The coupling portion 500 according to another embodiment of the present disclosure may further include a chamfered portion 503 a .

[0370] The coupling portion 500 may include a hollow portion 501 connected to the inner space 313 of the housing 310, and include a chamfered portion 503a. The chamfered portion 503a may be configured at the hollow portion 501. For example, the hollow portion 501 may be connected to the inner space 313 of the housing 310 through the opening portion 310o of the housing 310.

[0371] The vehicle interior material 130 may include a first surface and a second surface different from (or opposite to) the first surface. The first surface may be a surface facing the housing 310. The vehicle interior material 130 may include holes 137 configured at the first surface and the second surface. For example, the hole 137 of the vehicle interior material 130 may be configured to pass through the first surface and the second surface. For example, the latch member 503 may be configured to pass through the hole 137 and couple to the inner surface 130s of the vehicle interior material 130. For example, the latch member 503 may include a chamfered portion 503a. For example, the latch member 503 may overlap with the second surface 130s of the vehicle interior material 130.

[0372] The chamfered portion 503a according to another embodiment of the present disclosure may include a non-rectangular shape (or a non-right angle shape). For example, the chamfered portion 503a may include one or more of a curved shape (or a circular shape) and a sloped surface. For example, the chamfered portion 503a may have a curvature. The sound characteristics and / or sound pressure level characteristics may be changed 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 peak and / or the depression in the low-pitched vocal band to the high-pitched vocal band is improved, thereby enhancing the balance characteristic of the sound pressure level or the flatness characteristic of the sound pressure level. In addition, as the curvature of the chamfered portion 503a increases, the flatness characteristic and / or the sound pressure level characteristic of the sound pressure level in the high-pitched vocal band can be further enhanced. Therefore, since the coupling portion 500 is configured to have a circular shape or a sloped surface, the sound characteristics and / or sound pressure level characteristics in the vocal cords including the sound of the low-pitched vocal cords can be enhanced, and the peaks and / or dips in the high-pitched vocal cords can be improved, thereby enhancing the balance characteristics of the sound pressure level or the flatness characteristics of the sound pressure level.

[0373] Reference Fig.31 , the coupling portion 500 may include a first side portion (or lower surface) 500a and a second side portion (or upper surface) 500b. The second side portion 500b may be opposite to the first side portion 500a. For example, the chamfered portion 503a may be configured in an area between the second side portion 500b and the hollow portion 501. For example, the chamfered portion 503a may be configured in a non-rectangular shape in an area (corner area) between the inner surface (or inner surface) of the hollow member 502 and the upper surface of the hook member 503. For example, the hollow portion 501 may be connected to the internal space 313 through the opening portion 310o of the housing 310.

[0374] According to another embodiment of the present disclosure, the hollow portion 501 may have a "1" shape (or a straight line shape), but the embodiments of the present disclosure are not limited thereto. The hollow portion 501 may have a "1" shape parallel to the long side direction or the first direction X of the shell 310, but the embodiments of the present disclosure are not limited thereto. For example, the hollow portion 501 may have a slit shape including a short axis and a long axis, but the embodiments of the present disclosure are not limited thereto. For example, the long axis of the hollow portion 501 may be parallel to the long side direction or the first direction X of the shell 310, but the embodiments of the present disclosure are not limited thereto. For example, the short axis of the hollow portion 501 may be parallel to the second direction Y or the short side direction of the shell 310, but the embodiments of the present disclosure are not limited thereto. For example, the hollow portion 501 may have the above reference Fig.19 or Fig. 20The “*” shape (or asterisk shape) or the “+” shape (or cross shape) is described, but the embodiments of the present disclosure are not limited thereto. The shape of the chamfered portion 503 a may be identically applied based on various shapes of the hollow portion 501 .

[0375] According to another embodiment of the present disclosure, the coupling portion 500 may include a hollow portion 501 having a certain width (or first width) W. The hollow portion 501 of the coupling portion 500 may be configured to have a certain width W. For example, the width W of the hollow portion 501 may be the short axis length of the hollow portion 501. The width W of the hollow portion 501 or the short axis length of the hollow portion 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 portion 501 or the short axis length of the hollow portion 501 may be 1 mm to 5 mm or less, but the embodiments of the present disclosure are not limited thereto.

[0376] 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 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 portion 501 may 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.

[0377] 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, the sound characteristics and / or sound pressure level characteristics in the tonal vocal band including the sound of the low-pitched vocal band can be enhanced, and the peak and / or the dip in the high-pitched 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 or more, dust or particles flowing in from the outside can be reduced or minimized.

[0378] According to another embodiment of the present disclosure, the coupling portion 500 may include a latch member 503 having a certain length L (or a second width). For example, the latch member 503 may be configured to have a certain 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. The latch member 503 having the length L may overlap with at least one of the vehicle interior material 130, the connecting 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, but embodiments of the present disclosure are not limited thereto.

[0379] According to an embodiment of the present disclosure, as the length L of the coupling portion 500 or the latch member 503 is reduced, the sound pressure level characteristics can be enhanced. According to an embodiment of the present disclosure, the length L of the latch member 503 may be 10 mm or more, but the embodiment of the present disclosure is not limited thereto. For example, the length L of the latch member 503 may be 10 mm or more and less than 19 mm, but the embodiment of the present disclosure is not limited thereto. For example, when the length L of the latch member 503 is less than 10 mm, the sag and / or peak of the sound may be improved, but there may be a problem that it is difficult to equip the sound device in the roof trim of the vehicle equipment. According to an embodiment of the present disclosure, since the length L of the latch member 503 is configured to be 10 mm or more and less than 19 mm, the sound characteristics and / or sound pressure level characteristics in the tone vocal band of the sound including the low-pitched vocal band can be enhanced, and the peak and / or sag in the high-pitched vocal band can be improved, thereby enhancing the balance characteristics of the sound pressure level or the flatness characteristics of the sound pressure level.

[0380] According to another embodiment of the present disclosure, since the coupling portion 500 is configured to include one or more of the width W of the hollow portion 501 and the length L of the latch member 503 , the sound characteristics and / or sound pressure level characteristics of the sound device 30 may be further enhanced.

[0381] Refer to above Fig.30 and Fig.31 The coupling portion 500 described above can be applied to the Figure 25 to Figure 29 For example, the above referenced sound device 30 may be Figure 25 to Figure 29 The coupling portion 500 of the sound device 30 described above is changed to Fig.30 and Fig.31 For example, in the above reference Figure 25 to Figure 29 In the description of the sound device 30 described above, other descriptions besides the description of the coupling portion 500 may be included in Fig.30 and Fig.31 For example, according to another embodiment of the present disclosure, since the sound device 30 may include one or more holes 331o and may be configured to include one or more of the shape of the coupling portion 500, the width W of the coupling portion 500, and the length L of the coupling portion 500, the sound characteristics and / or sound pressure level characteristics of each of the low-pitched vocal band and the middle-pitched vocal band may be further enhanced, and the sound reproduction frequency band may be further expanded.

[0382] Fig.32 A sound device according to another embodiment of the present disclosure is shown. Fig.32 The above reference Fig.25 or Fig.30 Another embodiment of the connection member 380 is described. Therefore, in the following description, repeated descriptions of other elements except the connection member 380 are omitted or will be briefly given below.

[0383] In configuration Fig.25 or Fig.30 In the case of the connecting member 380, the inventors of the present disclosure have recognized that the sound characteristics and / or sound pressure level characteristics are reduced because the edge portion (or peripheral portion) of the connecting member 380 is not connected to or is not in contact with the vehicle interior material 130. For example, the inventors of the present disclosure have recognized that the loss of sound (or vibration transmission) occurs due to the peripheral portion of the connecting member 380 not being connected to or is not in contact with the vehicle interior material 130. Therefore, the inventors of the present disclosure have recognized that the sound characteristics and / or 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 sound pressure level characteristics of the low-pitched vocal cords. This will be described below.

[0384] Reference Fig.32 , the sound device 30 according to another embodiment of the present disclosure may further include a connecting member 380 .

[0385] The connecting member 380 may include a first portion and a second portion. The second portion may be a peripheral portion of the housing 310. The second portion may be a portion (or region) between the vehicle interior material 130 and the peripheral portion of the housing 310. The first portion may be a portion other than the peripheral portion of the housing 310. For example, the first portion may correspond to a central portion of the housing 310 surrounded by a second portion corresponding to the peripheral portion of the housing 310.

[0386] According to an embodiment of the present disclosure, the first portion of the connection member 380 may include an opening hole 380o connected to the inner space 313 of the housing 310. For example, the first portion of the connection member 380 may include an opening hole 380o connected to the inner space 313 of the first housing 311.

[0387] 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.

[0388] The first area A1 may correspond to the central portion of the housing 310 or the first housing 311. The first area A1 may be at the central portion of the housing 310 or the first housing 311. The second area A2 may correspond to the peripheral portion of the housing 310 or the first housing 311 surrounding the central portion. The third area A3 may be between the first area A1 and the second area A2. For example, the first portion of the connecting member 380 may be at the first area A1 and the third area A3. For example, the second portion of the connecting member 380 may be at the second area A2.

[0389] According to an embodiment of the present disclosure, the first and second parts of the connecting member 380 may have different thicknesses. For example, the connecting member 380 may include a first and second parts having different thicknesses. In the connecting member 380, the thickness T1 of the first part may be different from the thickness "T1+T2" of the second part. For example, in the connecting member 380, the thickness "T1+T2" of the second part may be thicker than the thickness T1 of the first part. For example, the thickness T1 of the connecting member 380 at the first area A1 may be different from the thickness "T1+T2" of the connecting member 380 at the second area A2. At least one thickness of the connecting member 30 at each of the first area A1 and the third area A3 may be different from the thickness "T1+T2" of the connecting member 380 at the second area A2. For example, the thickness "T1+T2" of the connecting member 380 at the second area A2 may be thicker than the thickness T1 of the connecting member 380 at the first area A1.

[0390] According to an embodiment of the present disclosure, the second portion of the connecting member 380 may have a thickness "T1+T2" thicker than the first portion, and therefore, the peripheral portion of the connecting member 380 may be connected to or in contact with the vehicle interior material 130 without being partially disassembled (or lifted up). Therefore, the peripheral portion of the connecting member 380 may be prevented from being partially disassembled (or lifted up) from the vehicle interior material 130, and the vibration at the peripheral portion of the housing 310 may be transmitted to the vehicle interior material 130 without losing the vibration (or vibration transmission) at the peripheral portion of the housing 310. The vibration at the peripheral portion of the housing 310 may increase the vibration area of ​​the vehicle interior material 130, and therefore, the sound characteristics of the low-pitched vocal cords may be further improved or strengthened. Therefore, the sound generated by the vibration of the sound device 30 may be transmitted to the vehicle interior material 130 without loss, and therefore, the sound of the low-pitched vocal cords may be further 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 portion 310o and the peripheral portion of the shell 310, and therefore, the efficiency of the vibration transmitted from the shell 310 to the vehicle interior material 130 can be improved, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band.

[0391] The connection member 380 according to an embodiment of the present disclosure may include a first connection member 381 and a second connection member 382 .

[0392] The first connecting member 381 may be at the first portion and the second portion. 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 to third areas 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.

[0393] According to an embodiment of the present disclosure, the first connection member 381 may include a hole 380o at a first portion and connected to the inner space 313 of the housing 310. For example, the first connection member 381 may include a hole 380o at a first portion and connected to the inner space 313 of the first housing 311.

[0394] The second connecting member 382 may be at the second portion. The second connecting member 382 may be connected to a portion of the first connecting member 381. The second connecting member 382 may be on the first connecting member 381 at the second portion. For example, the first portion may include only the first connecting member 381 of the first connecting member 381 and the second connecting member 382. The first connecting member 381 and the second connecting member 382 may be together at the second portion. For example, the second portion may include all of 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 area A2.

[0395] The first and second portions of the connection member 380 may have different widths (or sizes). In the connection member 380, the width of the first portion may be smaller than the width of the second portion. For example, the width of the connection member 380 at the first area A1 and the third area A3 may be smaller than the width of the connection member 380 at the second area A2. Therefore, the connection member 380 may include a first portion and a second portion having different sizes (or widths) and different thicknesses.

[0396] 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 portion. The second connecting member 382 may be configured to be stacked on the first connecting member 381 at the second area A2. Therefore, the thickness "T1+T2" of the second portion of the connecting member 380 may be thicker than the thickness T1 of the first portion, and therefore, the peripheral portion of the housing 310 may be connected to (or in contact with) the vehicle interior material 130 without being partially disassembled (or lifted). For example, the second connecting member 382 may be a buffer member or a pad member, but embodiments of the present disclosure are not limited thereto.

[0397] The first connecting member 381 can be Fig.25 or Fig.30 The described connection members 380 are substantially the same, and therefore, a repeated description thereof is omitted.

[0398] The second connecting member 382 may include the same material (or substance) as the material 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 relatively high elastic (or Young's modulus) material. One of the first connecting member 381 and the second connecting member 382 may be configured to be configured with a high elastic rubber, 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 relatively high elastic (or Young's modulus) material and may include a relatively high tensile strength material. 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-grade rubber), ethylene propylene rubber or polyurethane rubber. For example, 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 50kg / cm 2 Up to 200kg / cm 2 , but the embodiments of the present disclosure are not limited thereto. For example, the minimum elongation 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.

[0399] According to an embodiment of the present disclosure, the coupling member 320 may be configured as a material different from that of the connection member 380. For example, one of the first connection member 381 and the second connection member 382 may be configured as a material having higher elasticity (or Young's modulus) than that of the coupling member 320.

[0400] According to an embodiment of the present disclosure, the width of the connection member 380 at the second portion may be greater than the width of the coupling member 320. For example, the width of the connection member 380 at the second area A2 may be greater than the width of the coupling member 320.

[0401] According to an embodiment of the present disclosure, each of the first connection member 381 and the second connection member 382 of the connection member 380 may have a compressive force (or a shrinkage force) and an elastic restoring force, and may be shrunk or compressed by the coupling between the coupling portion 500 and the first shell 311. For example, the first connection member 381 disposed (or inserted) between the first shell 311 and the vehicle interior material 130 may have a first thickness T1 obtained by pressure compression of the first shell 311. The second connection member 382 disposed (or inserted) between the first shell 311 and the vehicle interior material 130 may have a second thickness T2 obtained by pressure compression of the first shell 311.

[0402] The first thickness T1 of the first connection member 381 may be equal to or different from the second thickness T2 of the second connection member 382. The first thickness T1 of the first connection member 381 and the second thickness T2 of the second connection member 382 may each be 0.5 mm or more, but embodiments of the present disclosure are not limited thereto. For example, the first thickness T1 of the first connection member 381 and the second thickness T2 of the second connection member 382 may each be 0.5 mm to 3 mm, but embodiments of the present disclosure are not limited thereto.

[0403] The sound device 30 according to another embodiment of the present disclosure may further include an air gap AG at an area between the housing 310 and the vehicle interior material 130. For example, the air gap AG may be at an area between the vehicle interior material 130 and the first portion of the connecting member 380, or at an area between the first portion and the second portion of the connecting member 380. For example, the air gap AG may be at a third area A3 between the first area A1 and the second area A2 of the housing 310. For example, the air gap AG may be at an area between the third area A3 of the housing 310 and the vehicle interior material 130. For example, the air gap AG may be provided at the third area A3 between the first area A1 and the second area A2 of the housing 310, and thus the separation or interference between the vibration of the first area A1 and the vibration of the second area A2 may be minimized, thereby increasing the vibration force (or vibration amount) transmitted from the second area A2 (e.g., the peripheral portion) of the housing 310 to the vehicle interior material 130. Therefore, the frequency band (reproduction frequency band) of the low-pitched vocal band may be expanded, and thus the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band may also be improved.

[0404] According to an embodiment of the present disclosure, a connecting member 380 including a first portion and a second portion having different thicknesses may be configured, thereby providing a sound device 30 that further enhances the sound characteristics and / or sound pressure level characteristics of a low-pitched vocal band. According to an embodiment of the present disclosure, since the second connecting member 382 is configured, when the sound device 30 is coupled to a roof trim of a vehicle device, the vibration zone (or vibration area) of the roof trim of the vehicle device may be widened, and therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band may be further enhanced.

[0405] Fig.33 Another embodiment according to the present disclosure is shown. Fig.32 The connection method between the sound device and the coupling part is shown.

[0406] Reference Fig.32 and Fig.33 According to an embodiment of the present disclosure, the first connecting member 381 of the connecting member 380 can be connected (or attached) to the rear surface (or the first part and the second part) of the shell 310 or the first shell 311 so that the hole 380o overlaps with the shell 310 or the first shell 311 (or is connected to the shell 310 or the first shell 311), and the second connecting member 382 of the connecting member 380 can be connected (or attached) to the outer portion (or the second portion) of the first connecting member 381.

[0407] The housing 310 or the first housing 311 may be disposed on the vehicle interior material 130 so that the opening portion 310o overlaps with (or is connected to) the hole 137 of the vehicle interior material 130. At the inner space (or indoor 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 137 (arrow direction) of the vehicle interior material 130. For example, at 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 second hole 137 of the vehicle interior material 130 and the hole 380o (arrow direction) of the first connecting member 381. For example, at the inner space of the vehicle, the coupling portion 500 may be accommodated or inserted into the hole 137 of the vehicle interior material 130, the hole 380o of the first connecting member 381, and the opening portion 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 portion 310o of the first housing 311. For example, the hook member 504 of the coupling portion 500 may be inserted (or accommodated) into the opening portion 310o of the first housing 311, and may be connected or coupled to the groove portion 311g of the first housing 311 based on the hook coupling scheme.

[0408] Therefore, the first shell 311 can be connected (or contact) with the interior material 130 and coupled to the coupling part 500 through the first and second connection members 381 and 382, ​​and can vibrate the vehicle interior material 130 to output sound based on the vibration of the vibration device.

[0409] The first connection member 381 may have an initial thickness T1' before being compressed (or contracted), and may be compressed (or contracted) to have a deformed thickness (or compressed thickness) T1 based on a pressure applied from the housing 310 through 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, the thickness of the first connection member 381 may be compressed from the initial thickness T1' to the compressed thickness T1 based on a pressure applied from the housing 310, and thus, the vibration of the first area A1 in the first housing 311 may be efficiently transmitted to the vehicle interior material 130 through the first portion of the first connection member 381. For example, when the sound device 30 is separated (or disassembled) from the vehicle interior material 130 by disassembling the coupling portion 500, the first connection member 381 may be restored from the deformed thickness (or compressed thickness) T1 to the initial thickness T1' by an elastic restoring force.

[0410] The second connection member 382 may have an initial thickness T2' before being compressed (or contracted), 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, the thickness of the second connection member 382 may be compressed from the initial thickness T1' to the compressed thickness T1 based on the pressure applied by the housing 310, and thus, the vibration of the second area A2 at the first housing 311 may be efficiently transmitted to the vehicle interior material 130 through the compressed (or contracted) first connection member 381 and the first portion of the second connection member 381. For example, when the sound device 30 is separated (or disassembled) from the vehicle interior material 130 by disassembling the coupling portion 500, the second connection member 382 may be restored from the deformed thickness (or compressed thickness) T2 to the initial thickness T2' by the elastic restoring force.

[0411] Based on the coupling (or connection) between the coupling portion 500 and the shell 310, the vehicle interior material 130 connected to (or in contact with) the shell 310 or the first shell 311 can be deformed to include a zigzag portion or at least one bent portion, and thus, partial disassembly (or lifting or separation) between the outer portion of the shell 310 or the first shell 311 and the vehicle interior material 130 can be prevented by the second portion of the connecting member 380 having a relatively thick thickness. Therefore, the vibration at the outer portion of the shell 310 or the first shell 311 based on the vibration of the vibration device can be transmitted to the vehicle interior material 130 without losing the vibration (or vibration transmission) at the outer portion of the first shell 311, and thus, the vibration efficiency transmitted from the shell 310 to the vehicle interior material 130 can be improved, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band.

[0412] According to another embodiment of the present disclosure, the above reference Figures 25 to 31 The connecting member 380 described above is changed to include Fig.32 and Fig.33 The connecting member 380 of the first connecting member 381 and the second connecting member 382 described above, and therefore, Figures 25 to 31 In the described sound device 30, the sound characteristics and / or the sound pressure level characteristics of each of the low-pitched vocal band and the middle-pitched vocal band can be more enhanced, and the sound reproduction frequency band can be more expanded.

[0413] Fig.34 A sound device according to another embodiment of the present disclosure is shown. Fig.34 The above reference Fig.32 and Fig.33 Another embodiment of the connecting member 380 is described. Therefore, in the following description, repeated descriptions of other elements except the connecting member 380 are omitted or may be briefly given below. Fig.32 and Fig.33 The description of the housing 310 or the first housing 311 and the description of the connecting member 380 may be included in the description of Fig.34 in the description.

[0414] Reference Fig.34 , the sound device 30 according to another embodiment of the present disclosure may further include a connecting member 380 .

[0415] The connecting member 380 may include a first portion and a second portion. The first portion of the connecting member 380 may include a hole 380o connected to the inner space 313 of the housing 310. For example, the first portion of the connecting member 380 may include a hole 380o connected to the inner space 313 of the first housing 311. The housing 310 or the first housing 311 may include a first area A1, a second area A2, and a third area A3.

[0416] According to an embodiment of the present disclosure, the first and second parts of the connecting member 380 may have different thicknesses T3 and T4. For example, the connecting member 380 may include a first and 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 area A1 may be different from the thickness T4 of the connecting member 380 at the second area A2. For example, the thickness T4 of the connecting member 380 at the second area A2 may be thicker than the thickness T3 of the connecting member 380 at the first area A1. For example, the connecting member 380 may not be disposed at the third area A3 between the first area A1 and the second area A2 or at the part between the first part and the second part.

[0417] According to an embodiment of the present disclosure, the second portion of the connecting member 380 may have a thickness T4 thicker than the first portion, and therefore, the peripheral portion of the connecting member 380 may be connected to or in contact with the vehicle interior material 130 without being partially disassembled (or lifted up). Therefore, the peripheral portion of the connecting member 380 may be prevented from being partially disassembled (or lifted up) from the vehicle interior material 130, and the vibration at the peripheral portion of the housing 310 may be transmitted to the vehicle interior material 130 without losing the vibration (or vibration transmission) at the peripheral portion of the housing 310. The vibration at the peripheral portion of the housing 310 may increase the vibration area of ​​the vehicle interior material 130, and therefore, the sound characteristics of the low-pitched vocal cords may be further improved or strengthened. Therefore, the sound generated by the vibration of the sound device 30 may be transmitted to the vehicle interior material 130 without loss, and therefore, the sound of the low-pitched vocal cords may be further 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 portion 310o and the peripheral portion of the shell 310, and therefore, the efficiency of the vibration transmitted from the shell 310 to the vehicle interior material 130 can be improved, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band.

[0418] According to an embodiment of the present disclosure, the connection member 380 may include a first connection member 383 and a second connection member 384 .

[0419] The first connecting member 383 may be connected to the housing 310. The first connecting member 383 may be at the first part. The first connecting member 383 may be only at the first part of the first part and the second part. The first connecting member 383 may be connected to (or attached to) the first housing 311 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. The first connecting member 383 may be connected to (or attached to) the rear surface of the first housing 311 corresponding to the first part of the first part and the second part. For example, the first connecting member 383 may be connected to (or attached to) the center part (or rear center part) of the first housing 311 (or attached to). For example, the first connecting member 383 may be connected to (or attached to) only the first area A1 of the first to third areas A1, A2 and A3 of the housing 310.

[0420] According to an embodiment of the present disclosure, the first connection member 383 may include a hole 380o at a first portion and connected to the inner space 313 of the housing 310. For example, the first connection member 383 may include a hole 380o at a first portion and connected to the inner space 313 of the first housing 311.

[0421] The second connecting member 384 may be at the second part. The second connecting member 384 may be only at the second part of the first part and the second part, and may be spaced apart from the first connecting member 383. The second connecting member 384 may be at the second part of the first part and the second part to surround the first connecting member 383, wherein the 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 area A2 of the housing 310. For example, the second connecting member 384 may be connected to (or attached to) the rear surface of the second part of the first part and the second part of the first housing 311. For example, the second connecting member 384 may be connected to (or attached to) the peripheral part (or rear peripheral part) of the first housing 311 (or attached thereto). For example, the second connecting member 384 may be connected only to (or attached to) the second area A2 of the first to third areas A1, A2 and A3 of the housing 310.

[0422] The first and second portions of the connecting member 380 may have different widths (or sizes). The width of the first portion may be smaller than the width of the second portion. For example, the width of the first connecting member 383 at the first area A1 may be smaller than the width of the second connecting member 384 at the second area A2. Therefore, the first connecting member 383 and the second connecting member 384 may include different sizes (or widths) and different thicknesses.

[0423] Each of the first connection member 383 and the second connection member 384 may be a buffer member or a pad member, but embodiments of the present disclosure are not limited thereto.

[0424] The first connecting member 383 may include the same material (or substance) as the second connecting member 384. Each of the first connecting member 383 and the second connecting member 384 may be a highly elastic rubber or the like, but the 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-grade rubber), ethylene propylene rubber, or polyurethane rubber.

[0425] According to an embodiment of the present disclosure, the width of the connection member 380 at the second portion may be greater than the width of the coupling member 320. For example, the width of the connection member 380 at the second area A2 may be greater than the width of the coupling member 320.

[0426] According to an embodiment of the present disclosure, each of the first connection member 383 and the second connection member 384 of the connection member 380 may have a compressive force (or a shrinkage force) and an elastic restoring force, and may be shrunk or compressed by the coupling between the coupling portion 500 and the first shell 311. For example, the first connection member 383 disposed (or inserted) between the first shell 311 and the vehicle interior material 130 may have a first thickness (or a third thickness) T3 obtained by pressure compression of the first shell 311. The second connection member 384 disposed (or inserted) between the first shell 311 and the vehicle interior material 130 may have a second thickness (or a fourth thickness) T4 obtained by pressure compression of the first shell 311.

[0427] The first thickness T3 of the first connecting member 383 may be different from the second thickness T4 of the second connecting member 382. The first thickness T3 of the first connecting member 383 and the second thickness T4 of the second connecting member 384 may each be 0.5 mm or more, but the 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 each be 0.5 mm to 3 mm, but the 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 in the range of 0.5 mm to 3 mm. For example, in 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.

[0428] 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 at an area between the vehicle interior material 130 and the first portion of the connecting member 380, or at an area between the first portion and the second portion of the connecting member 380. For example, the air gap AG may be at a third area A3 between the first area A1 and the second area A2 of the housing 310. For example, the air gap AG may be at an area between the second area A2 of the housing 310 and the vehicle interior material 130. For example, the air gap AG may be provided at a third area A3 between the first area A1 and the second area A2 of the housing 310, and thus the separation or interference between the vibration of the first area A1 and the vibration of the second area A2 may be minimized, thereby increasing the vibration force (or amount of vibration) transmitted from the second area A2 (e.g., the peripheral portion) of the housing 310 to the vehicle interior material 130. Therefore, the frequency band (reproduction frequency band) of the low-pitched vocal band may be expanded, and thus the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band may also be improved.

[0429] According to an embodiment of the present disclosure, a connection member 380 including a first connection member 383 and a second connection member 384 having different thicknesses T3 and T4 may be configured, thereby providing a sound device 30 in which the sound characteristics and / or the 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 384 is configured, when the sound device 30 is coupled to a roof trim of a vehicle device, the vibration zone (or vibration area) of the roof trim of the vehicle device may be widened, and therefore, the sound characteristics and / or the sound pressure level characteristics of the low-pitched vocal cords may be further enhanced.

[0430] Fig.35 Another embodiment according to the present disclosure is shown. Fig.34 The connection method between the sound device and the coupling part is shown.

[0431] Reference Fig.34 and Fig.35 According to an embodiment of the present disclosure, the first connecting member 383 of the connecting member 380 can be connected (or attached) to the central portion (or first portion) of the shell 310 or the first shell 311 so that the hole 380o overlaps with the shell 310 or the first shell 311 (or is connected to the shell 310 or the first shell 311), and the second connecting member 384 of the connecting member 380 can be connected (or attached) to the outer portion (or second portion) of the shell 310 or the first shell 311.

[0432] The housing 310 or the first housing 311 may be disposed on the vehicle interior material 130 so that the opening portion 310o overlaps with the hole 137 of the vehicle interior material 130 (or is connected to the hole 137 of the vehicle interior material 130). At the inner space (or indoor 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 137 (arrow direction) of the vehicle interior material 130. For example, at 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 second hole 137 of the vehicle interior material 130 and the hole 380o (arrow direction) of the first connecting member 383. For example, at the inner space of the vehicle, the coupling portion 500 may be accommodated or inserted into the hole 137 of the vehicle interior material 130, the hole 380o of the first connecting member 383, and the opening portion 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 portion 310o of the first housing 311. For example, the hook member 504 of the coupling portion 500 may be inserted (or accommodated) into the opening portion 310o of the first housing 311, and may be connected or coupled to the groove portion 311g of the first housing 311 based on the hook coupling scheme.

[0433] Therefore, the first shell 311 can be connected (or contact) with the interior material 130 and coupled to the coupling portion 500 through the first and second connection members 383 and 384, and can vibrate the vehicle interior material 130 to output sound based on the vibration of the vibration device.

[0434] The first connection 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 portion 500 and the housing 310. For example, when the coupling portion 500 is coupled (or connected) to the housing 310, the thickness of the first connection member 383 may be compressed from the initial thickness T3' to the compressed thickness T3 based on the pressure applied from the housing 310, and thus, the vibration of the first area A1 in the first housing 311 may be effectively transmitted to the vehicle interior material 130 through the first connection member 381. For example, when the sound device 30 is separated (or disassembled) from the vehicle interior material 130 by disassembling the coupling portion 500, the first connection member 383 may be restored from the deformed thickness (or compressed thickness) T3 to the initial thickness T3' by the elastic restoring force.

[0435] The second connection member 384 may have an initial thickness T4' before being compressed (or contracted), 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 (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, the thickness of the second connection member 384 may be compressed from the initial thickness T4' to the compressed thickness T4 based on the pressure applied from the housing 310, and thus, the vibration of the second area A2 at the first housing 311 may be effectively transmitted to the vehicle interior material 130 through the compressed (or contracted) second connection member 384. For example, when the sound device 30 is separated (or disassembled) from the vehicle interior material 130 by disassembling the coupling portion 500, the second connection member 384 may be restored from the deformed thickness (or compressed thickness) T4 to the initial thickness T4' by the elastic restoring force.

[0436] Based on the coupling (or connection) between the coupling portion 500 and the shell 310, the vehicle interior material 130 connected to (or in contact with) the shell 310 or the first shell 311 can be deformed to include a zigzag portion or at least one bent portion, and thus, partial disassembly (or lifting or separation) between the outer portion of the shell 310 or the first shell 311 and the vehicle interior material 130 can be prevented by the second connecting member 384 having a relatively thick thickness. Therefore, the vibration at the outer portion of the shell 310 or the first shell 311 based on the vibration of the vibration device can be transmitted to the vehicle interior material 130 without losing the vibration (or vibration transmission) at the outer portion of the first shell 311, and thus, the vibration efficiency transmitted from the shell 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 band.

[0437] According to another embodiment of the present disclosure, the above reference Figures 25 to 31 The connecting member 380 described above is changed to include Fig.34 and Fig.35 The connecting member 380 of the first connecting member 381 and the second connecting member 382 described above, and therefore, Figures 25 to 31 In the described sound device 30, the sound characteristics and / or the sound pressure level characteristics of each of the low-pitched vocal band and the middle-pitched vocal band can be more enhanced, and the sound reproduction frequency band can be more expanded.

For example, the vehicle interior material 130 may output sound based on the vibration of one or more first sound generating devices 30-1. For example, the vehicle interior material 130 may be exposed to the inner space IS.
