For example, the first sub-region 300B1 and the second sub-region 300B2 in each of the first region 300A1 and the second region 300A2 may have the same dimensions or area in the rear portion 310. For example, the centerline CL2 having the second length may be a second centerline or a vertical centerline, and may be referred to as the second centerline CL2 in the following description. For example, the second direction Y may be another of the Y-axis direction, the length direction, the vertical direction, or the XYZ axis direction of the support member 300.

[0244] The support member 300 may also include a reinforcing portion 320 disposed at the rear 310.

[0245] The reinforcing portion 320 may be implemented to enhance the rigidity of the support member 300. Therefore, the reinforcing portion 320 may be a reinforcing member, a reinforcing pattern, a reinforcing pattern portion, a rigid portion, a rigid reinforcing member, a rigid pattern, or a rigid pattern portion, but the embodiments of this disclosure are not limited thereto.

[0246] The reinforcing portion 320 may include a first reinforcing portion 321 disposed along the rear peripheral portion of the support member 300. For example, the first reinforcing portion 321 may be disposed along the peripheral portion of the rear portion 310 of the support member 300. For example, the first reinforcing portion 321 may be implemented by protruding in a direction from the peripheral portion of the rear portion 310 of the support member 300 to the rear surface of the support member 300 to have a predetermined height. The first reinforcing portion 321 may enhance the rigidity of the support member 300 or the rear portion 310 of the support member 300, thereby preventing or reducing bending of the equipment or vibrating member 100.

[0248] The vibration device 500 can be disposed at the support member 300 and can be configured to cause the vibration member 100 to vibrate. The vibration device 500 according to an exemplary embodiment of this disclosure may include a membrane vibration device or a membrane-type vibration device. Therefore, the vibration device 500 may be referred to as a sound generating device, a sound generating apparatus, a sound generating member, a sound generator, a vibration source, an active vibration member, an active vibration device, an active vibration apparatus, a piezoelectric vibration device, a piezoelectric vibration member, a piezoelectric vibration apparatus, a piezoelectric vibrator, a piezoelectric vibration generator, a flexible vibration generator, a flexible actuator, a flexible loudspeaker, a flexible piezoelectric loudspeaker, a membrane actuator, a membrane-type piezoelectric composite actuator, a membrane loudspeaker, a membrane-type piezoelectric loudspeaker, or a membrane-type piezoelectric composite loudspeaker, etc., but the embodiments described in this specification are not limited thereto.

[0249] The vibration device 500 can be supported by the support member 300. The vibration device 500 can be coupled to or attached to the rear portion 310 of the support member 300. For example, the vibration device 500 can be installed with prestress applied to the rear portion 310 of the support member 300. For example, the vibration device 500 can be installed at the rear portion 310 of the support member 300 with a non-planar (or non-flat) structure. For example, the vibration device 500 can be installed at the rear portion 310 of the support member 300 with a curved shape or curved structure.

[0250] The vibration device 500 according to an exemplary embodiment of the present disclosure may include a first vibration device 500-1 and a second vibration device 500-2.

[0251] Each of the first vibration device 500-1 and the second vibration device 500-2 can be a diaphragm vibration device. Each of the first vibration device 500-1 and the second vibration device 500-2 can be disposed at the rear peripheral portion of the support member 300. For example, the first vibration device 500-1 and the second vibration device 500-2 can be arranged in parallel, with the second reinforcing portion 322 of the reinforcing portion 320 located between the first vibration device 500-1 and the second vibration device 500-2. For example, the first vibration device 500-1 and the second vibration device 500-2 can be arranged to have a symmetrical structure (or a left-right symmetrical structure) or an asymmetrical structure (or a left-right asymmetrical structure) with respect to the first centerline CL1 of the support member 300.

[0252] The first vibration device 500-1 can be disposed at the first rear peripheral portion of the support member 300. For example, the first vibration device 500-1 can be disposed at the first region 300A1 of the support member 300. For example, the first vibration device 500-1 can be disposed near the first rear peripheral portion.

[0253] According to an exemplary embodiment of this disclosure, the central portion (or central part or intermediate part) CP of the first vibration device 500-1 may be aligned with or positioned at the second centerline CL2 of the support member 300. For example, the central portion (or central part or intermediate part) CP of the first vibration device 500-1 may be disposed on the second centerline CL2 within the first region 300A1 of the support member 300, between the first centerline CL1 of the support member 300 and the first sidewall (or first short side or first side) of the support member 300. For example, the first vibration device 500-1 may be disposed within the first region 300A1 of the support member 300, between the first reinforcing portion 321 and the second reinforcing portion 322. For example, within the first region 300A1 of the support member 300, the first vibration device 500-1 may be configured to be closer to the first sidewall of the support member 300 than closer to the first centerline CL1 of the support member 300.

[0254] According to another exemplary embodiment of this disclosure, the central portion (or central part or intermediate part) CP of the first vibration device 500-1 may be spaced apart from the second centerline CL2 of the support member 300. For example, the central portion (or central part or intermediate part) CP of the first vibration device 500-1 may be located in a first sub-region 300B1 of the first region 300A1. For example, the central portion (or central part or intermediate part) CP of the first vibration device 500-1 may be located in the first sub-region 300B1 of the first region 300A1 at a predetermined separation distance ΔL from the second centerline CL2 of the support member 300. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated by the vibration of the first vibration device 500-1 can be enhanced.

[0255] For example, when the device according to the exemplary embodiment of this disclosure is applied to a display device, the lowermost (or lowest) portion of the second sub-region 300B2 of the support member 300 can be used as a propping portion. Therefore, it can be a free end that can freely move or vibrate from the lowermost portion of the second sub-region 300B2 toward the uppermost portion of the first sub-region 300B1 during vibration of the support member 300. Therefore, when the central portion CP of the first vibration device 500-1 is spaced apart from the second centerline CL2 of the support member 300 and located in the first sub-region 300B1, the vibration width (or displacement width) of the first vibration device 500-1 corresponding to the same driving signal can be increased more significantly compared to when the central portion CP of the first vibration device 500-1 is located at the second centerline CL2 of the support member 300. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated by the vibration of the first vibration device 500-1 can be enhanced.

[0256] The second vibration device 500-2 can be disposed at the second rear peripheral portion of the support member 300. For example, the second vibration device 500-2 can be disposed at the second region 300A2 of the support member 300. For example, the second vibration device 500-2 can be disposed near the second rear peripheral portion.

[0257] According to an exemplary embodiment of this disclosure, the central portion (or central part or intermediate part) CP of the second vibration device 500-2 may be aligned with or located at the second centerline CL2 of the support member 300. For example, the central portion (or central part or intermediate part) CP of the second vibration device 500-2 may be disposed on the second centerline CL2 within the second region 300A2 of the support member 300, between the first centerline CL1 of the support member 300 and the second sidewall (or second short side or second side) of the support member 300. For example, the second vibration device 500-2 may be disposed within the second region 300A2 of the support member 300, between the first reinforcing portion 321 and the second reinforcing portion 322. For example, within the second region 300A2 of the support member 300, the second vibration device 500-2 may be positioned closer to the second sidewall of the support member 300 than closer to the first centerline CL1 of the support member 300.

[0258] According to another exemplary embodiment of this disclosure, the central portion (or middle portion or intermediate portion) CP of the second vibration device 500-2 may be spaced apart from the second centerline CL2 of the support member 300. For example, the central portion (or middle portion or intermediate portion) CP of the second vibration device 500-2 may be located in a first sub-region 300B1 of the second region 300A2. For example, the central portion (or middle portion or intermediate portion) CP of the second vibration device 500-2 may be located in the first sub-region 300B1 of the second region 300A2 at a predetermined separation distance ΔL from the second centerline CL2 of the support member 300. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated by the vibration of the second vibration device 500-2 can be enhanced.

[0259] Each of the first vibration device 500-1 and the second vibration device 500-2 can vibrate based on a drive signal, which includes a sound signal and a tactile feedback signal, or includes a sound signal (or voice signal) input from an external source, to cause the vibrating member 100 to vibrate. Therefore, each of the first vibration device 500-1 and the second vibration device 500-2 can generate sound S based on the vibration of the vibrating member 100, or can generate tactile feedback (or tactile vibration) in response to a user touch.

[0260] A device according to another exemplary embodiment of the present disclosure can generate sound S and / or tactile feedback (or tactile vibration) based on the vibration of a vibrating member 100 driven by a vibration device 500. For example, the sound S generated based on the vibration of the vibrating member 100 can be output in the forward direction of the vibrating member 100 or in the forward direction of the screen. For example, a device according to an exemplary embodiment of the present disclosure can output left and right sounds in the forward direction of the vibrating member 100 or in the forward direction of the screen based on the vibration of the vibrating member 100 driven by each of the first vibration device 500-1 and the second vibration device 500-2, and can achieve sound, for example, stereo sound through the left and right sounds. Therefore, a device according to an exemplary embodiment of the present disclosure can use the vibrating member 100 including a display panel as a vibrating plate for generating (or outputting) sound and output sound in the forward direction of the vibrating member 100 or in the forward direction of the screen, thus enabling the transmission of more precise sound, thereby improving sound quality and / or sound and enhancing the viewer's immersion.

[0261] Figure 3 It is along Figure 1 The example cross-section shown is taken by line I-I'. Figure 3 The cross-sectional structure of a support member according to an exemplary embodiment of the present disclosure is illustrated.

[0262] Reference Figure 3 In an example embodiment of the device according to the present disclosure, the support member 300 may include a rear portion 310, a side portion 330, and a curved portion 350.

[0263] The rear portion 310 may be disposed in the rear surface of the vibrating member 100. The rear portion 310 may include a base plate surface (bottom surface or support surface) 310a that supports the vibrating member 100. The rear portion 310 may be related to the above description. Figure 1 and Figure 2 The latter part 310 is essentially the same as described above, so its repeated description is omitted for brevity. Figure 1 and Figure 2 The enhanced part of the description.

[0264] Side portion 330 may be connected to the peripheral portion of rear portion 310. Side portion 330 may be implemented to support vibration member 100. Side portion 330 may be implemented to have a predetermined height along the peripheral portion of rear portion 310, thus providing receiving space on the base plate surface 310a of rear portion 310. For example, side portion 330 may bend from the peripheral portion of rear portion 310. For example, side portion 330 may be a sidewall portion or a lateral cover portion, and embodiments of this disclosure are not limited thereto.

[0265] The curved portion 350 can be implemented at the rear portion 310. The curved portion 350 can vibrate together with the vibration of the vibration device 500 to cause the vibration member 100 to vibrate. For example, the curved portion 350 can be configured to vibrate based on the vibration of the vibration device 500 to indirectly cause the vibration member 100 to vibrate.

[0266] According to another exemplary embodiment of this disclosure, the curved portion 350 may be implemented at the rear portion 310 with a predetermined curvature. For example, the curved portion 350 may include a curved structure projecting in the direction from the rear portion 310 to the rear surface of the support member 300. For example, the curved portion 350 may project from the rear portion 310 to have a curved shape having a curvature (or a single curvature). For example, the curved portion 350 may have a curved structure having a curvature (or a single curvature) without inflection points. For example, the curved portion 350 may project convexly in the direction from the rear portion 310 to the rear surface of the support member 300. For example, the curved portion 350 may have a single convex curved shape having a specific curvature. For example, the curved portion 350 may be a curved protrusion, a base plate curved protrusion, a rear curved portion, a curved structure, a curvature structure, a forming portion, or a stress-applying portion, but embodiments of this disclosure are not limited thereto. For example, the curved portion 350 may be a curved portion, a recessed portion, a recessed curved portion, a recessed arched portion, a groove portion, or a recessed groove portion having a first shape relative to the bottom plate surface 310a of the rear portion 310 facing the vibrating member 100, but the embodiments of this disclosure are not limited thereto.

[0267] According to another exemplary embodiment of this disclosure, the central portion of the curved portion 350 may be spaced apart from the rear surface of the vibrating member 100. For example, the height (or distance) between the rear surface of the vibrating member 100 and the curved portion 350 may increase from the peripheral portion of the curved portion 350 toward the central portion of the curved portion 350. According to an embodiment of this disclosure, the curved portion 350 may be implemented having a first height H1 from the rear portion 310. For example, the first height H1 of the curved portion 350 may be the shortest distance between the bottom plate surface 310a of the rear portion 310 and the rearmost surface of the curved portion 350.

[0268] According to another exemplary embodiment of this disclosure, the first height H1 of the bent portion 350 can be set within a range that allows prestress to be applied to the vibration device 500. For example, the first height H1 of the bent portion 350 can be from about 2 mm to about 200 mm, but the exemplary embodiment of this disclosure is not limited thereto, and the first height H1 can vary based on the dimensions of the vibration device 500. The first height H1 of the bent portion 350 can be less than the second height H2 of the vibration member 100. For example, the second height H2 of the vibration member 100 can be the shortest distance between the bottom plate surface 310a of the rear portion 310 and the uppermost surface (or top surface) of the vibration member 100. For example, when the first height H1 of the bent portion 350 is greater than the second height H2 of the vibration member 100, the thickness of the device or display device may increase, and because of this, it may be difficult to make the device or display device thinner (or have a thinner thickness).

[0269] The curved portion 350 according to an exemplary embodiment of the present disclosure may include a first curved portion 350a and a second curved portion 350b.

[0270] The first curved portion 350a may be realized at the rear 310 corresponding to the first region 300A1 of the support member 300. For example, the first curved portion 350a may be configured to support the first vibration device 500-1. The first curved portion 350a may be implemented to vibrate together with the vibration of the first vibration device 500-1.

[0271] The second curved portion 350b may be implemented at the rear 310 corresponding to the second region 300A2 of the support member 300. For example, the second curved portion 350b may support the second vibration device 500-2. The second curved portion 350b may be implemented to vibrate together with the vibration of the second vibration device 500-2.

[0272] The vibration device 500 may be coupled to or attached to the curved portion 350. For example, the vibration device 500 may have a size smaller than that of the curved portion 350. The vibration device 500 may be coupled to or attached to the curved portion 350 to have an isoangular shape (or conformal shape) based on the curvature of the curved portion 350, but embodiments of this disclosure are not limited thereto. For example, the vibration device 500 may be coupled to or attached to the curved portion 350 to have an isoangular shape that conforms to the profile of the curvature of the curved portion 350. For example, the vibration device 500 may be coupled to or attached to the curved portion 350 to have a non-isoangular shape (or non-conformal shape) that is not based on the curvature of the curved portion 350 or has a curvature different from that of the curved portion 350. For example, the vibration device 500 may be coupled to or attached to the curved portion 350 to have a profile not based on the curvature of the curved portion 350 or a non-equiangular shape with a curvature different from that of the curved portion 350.

[0273] According to another exemplary embodiment of this disclosure, the vibration device 500 may be coupled to or attached to the bending portion 350, and thus may have or receive prestress based on the bending portion 350. For example, the vibration device 500 may be coupled to or attached to the bending portion 350, and thus may remain in a state where the vibration device 500 has or receives prestress based on the bending portion 350. For example, the vibration device 500 may receive tensile stress or include tensile stress based on the curvature of the bending portion 350. For example, the bending portion 350 may be implemented to apply only tensile stress to the vibration device 500 to enhance the vibration characteristics of the vibration device 500. For example, when the vibration device 500 receives compressive stress instead of tensile stress based on the bending portion 350, the vibration characteristics of the vibration device 500 may be reduced.

[0274] According to another exemplary embodiment of this disclosure, the vibration device 500 may include a state where the bending portion 350 is bent into a curved shape or can receive prestress (or pretension), thus increasing the second moment of inertia. In the vibration device 500, because the second moment of inertia increases, the number of resonant frequencies occurring during vibration can be reduced, and therefore the number of nodes (or joints or connection points) can be reduced, thereby enhancing the acoustic characteristics and / or sound pressure level characteristics. For example, in the vibration device 500, because the number of resonant frequencies decreases due to the increase in the second moment of inertia, the mode shape can be corrected, thus enhancing the sound pressure level characteristics and / or acoustic characteristics.

[0275] According to another exemplary embodiment of this disclosure, the vibration device 500 may include a state in which the vibration device 500 is bent into a curved shape based on the bending portion 350 or can receive prestress (or pretension). Therefore, the vibration direction (or displacement direction, bending direction, or driving direction) of the vibration device 500 can be realized as a single direction, and the dynamic displacement can be extended. Therefore, the sound generated by the vibration of the vibration device 500 can be concentrated in the direction toward the center of the bending portion 350, and the sound pressure level transmitted to the vibration member 100 can be increased or amplified. Thus, the sound characteristics and / or sound pressure level characteristics generated by the vibration of the vibration member 100 can be enhanced.

[0276] The first vibration device 500-1 of the vibration device 500 can be coupled to or attached to the first curved portion 350a. The first vibration device 500-1 can be coupled to or attached to the first curved portion 350a to have an isoangular shape based on the curvature of the first curved portion 350a, but embodiments of this disclosure are not limited thereto. For example, the first vibration device 500-1 can be coupled to or attached to the first curved portion 350a to have an isoangular shape conforming to the profile of the curvature of the first curved portion 350a. For example, the first vibration device 500-1 can be coupled to or attached to the first curved portion 350a to have a non-isoangular shape not based on the curvature of the first curved portion 350a or having a curvature different from the curvature of the first curved portion 350a. For example, the first vibration device 500-1 can be coupled to or attached to the first curved portion 350a, having a non-equiangular shape with a profile not based on the curvature of the first curved portion 350a. Therefore, the first vibration device 500-1 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape based on the first curved portion 350a, thus enabling the first vibration device 500-1 to vibrate the first curved portion 350a to generate sound or sound waves. Therefore, the first region of the vibrating member 100 overlapping with the first vibration device 500-1 can receive sound or sound waves generated by the vibration of the first curved portion 350a to vibrate, thus generating or outputting sound and / or tactile feedback.

[0277] The second vibration device 500-2 of the vibration device 500 can be coupled to or attached to the second curved portion 350b. The second vibration device 500-2 can be coupled to or attached to the second curved portion 350b to have an isoangular shape based on the curvature of the second curved portion 350b, but embodiments of this disclosure are not limited thereto. For example, the second vibration device 500-2 can be coupled to or attached to the second curved portion 350b to have an isoangular shape consistent with the profile of the curvature of the second curved portion 350b. For example, the second vibration device 500-2 can be coupled to or attached to the second curved portion 350b to have a non-isoangular shape not based on the curvature of the second curved portion 350b or having a curvature different from the curvature of the second curved portion 350b. For example, the second vibration device 500-2 can be coupled to or attached to the second curved portion 350b, having a non-equiangular shape with a profile not based on the curvature of the second curved portion 350b. Therefore, the second vibration device 500-2 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape based on the second curved portion 350b, thus causing the second vibration device 500-2 to vibrate the second curved portion 350b to generate sound or sound waves. Therefore, the second region of the vibrating member 100 overlapping with the second vibration device 500-2 can receive sound or sound waves generated by the vibration of the second curved portion 350b to vibrate, thus generating or outputting sound and / or tactile feedback.

For example, the optical sheet portion 113c may be configured as a single layer including a lower diffuser, a lower prism sheet, and an upper prism sheet. However, embodiments of this disclosure are not limited thereto, and the optical sheet portion 113c may be configured as a stacked combination of one or more sheets of a diffuser, a prism sheet, a dual brightness enhancement film, and a biconvex lens sheet, or it may be configured as a composite sheet having both light diffusion and light collection functions.

[0302] The guide member 115 may be disposed at the rear peripheral portion of the display panel 111 and may support the rear peripheral portion of the display panel 111. The guide member 115 may be supported by or contained within the support member 300 to overlap with the rear peripheral portion of the display panel 111. The guide member 115 may be disposed below the rear peripheral portion of the display panel 111 so as not to protrude beyond the outer side of each side surface of the display panel 111.

[0303] The guide member (or support frame) 115 according to an exemplary embodiment of the present disclosure may include a guide frame 115a and a guide side 115b. For example, the guide member 115 may have a cross-sectional structure with a "┓" (γ) shape or a "┏" (rotated "┓") shape based on the connection structure or link structure between the guide frame 115a and the guide side 115b, but the embodiments of the present disclosure are not limited thereto.

[0304] The guide frame 115a can be connected to the rear peripheral region of the display panel 111 and can be supported by the support member 300. For example, the guide frame 115a can have a quadrilateral strip (or strip) shape, which includes an opening that overlaps with the central portion of the display panel 111 excluding the rear peripheral region, but embodiments of the present disclosure are not limited thereto. For example, the guide frame 115a can directly contact the uppermost surface of the backlight member 113 (e.g., the uppermost surface of the optical sheet portion 113c), or it can be spaced a certain distance from the uppermost surface of the optical sheet portion 113c.

[0305] The guide side 115b may be connected to the guide frame 115a and may surround a portion or side surface of the support member 300. For example, the guide side 115b may bend from the guide frame 115a to the side surface of the support member 300 and may surround or be surrounded by the side surface of the support member 300.

[0306] The guide member 115 according to the exemplary embodiments of this disclosure may include a plastic material, a metal material, or a mixture of plastic and metal materials, but the embodiments of this disclosure are not limited thereto. For example, the guide member 115 may be used as a vibration transmission member to transmit sound vibrations generated by the vibration device 500 to the peripheral portion of the display panel 111. Therefore, the guide member 115 can transmit sound vibrations generated by the vibration device 500 to the display panel 111 without loss while maintaining the rigidity of the display panel 111. For example, the guide member 115 may include a metal material to transmit sound vibrations generated by the vibration device 500 to the display panel 210 without loss while maintaining the rigidity of the display panel 111, but the embodiments of this disclosure are not limited thereto.

[0307] According to an exemplary embodiment of this disclosure, the guide member 115 can be connected or coupled to the rear peripheral portion of the display panel 111 via a connecting member (or panel connecting member) 114. The connecting member 114 can be disposed between the rear peripheral portion of the display panel 111 and the guide member 115, and can also be used to set or couple the display panel 111 to the guide member 115. For example, the connecting member 114 may include an acrylic-based adhesive member or a polyurethane-based adhesive member, but embodiments of this disclosure are not limited thereto. For example, the connecting member 114 may include an acrylic-based adhesive member that is relatively better than a polyurethane-based adhesive member in terms of adhesion and hardness, such that vibrations of the guide member 115 can be well transmitted to the display panel 111. For example, the connecting member 114 may include a double-sided foam adhesive pad having an acrylic-based adhesive layer or an acrylic-based adhesive resin cured layer.

[0308] According to an exemplary embodiment of this disclosure, the front surface of the connecting member 114 can be disposed at the second substrate 111b or the first polarizing member 111c of the display panel 111. The connecting member 114 can be directly attached to the rear peripheral portion of the second substrate 111b to enhance adhesion to the display panel 111. For example, the connecting member 114 can surround the side surface of the first polarizing member 111c to prevent light leakage from the side surface in the first polarizing member 111c.

[0309] The connecting member 114 may have a certain thickness (or height). Therefore, the connecting member 114, together with the guide frame 115a of the guide member 115, can provide a sound transmission space STS between the display panel 111 and the backlight member 113. The connecting member 114 may be arranged in a quad-closed shape or a closed loop shape within the guide frame 115a of the guide member 115, but embodiments of this disclosure are not limited thereto. For example, the connecting member 114 may seal (or close) the sound transmission space STS between the last surface of the display panel 111 and the uppermost surface of the backlight member 113, with the opening of the guide member 115 between the last surface of the display panel 111 and the uppermost surface of the backlight member 113, thereby preventing or minimizing leakage (or loss) of sound pressure transmitted to the sound transmission space STS. The sound transmission space STS can also be used as a sound pressure level generation space, in which sound pressure is generated based on the vibration of the backlight member 113, or the sound transmission space STS can also be used as a panel vibration space that enables the smooth execution of the vibration of the display panel 111. For example, the sound transmission space STS can be a sound wave transmission section or a sound transmission section, but the embodiments of this disclosure are not limited thereto.

[0310] The support member 300 can be configured to support the vibration member 100. The support member 300 may include the components described above. Figure 3 The rear portion 310, the side portion 330, and the curved portion 350 are described.

[0311] The rear portion 310 can be configured to support or accommodate the backlight element 113 of the vibrating member 100. The base plate surface (or bottom surface or support surface) 310a of the rear portion 310 can contact or directly contact the rear surface of the backlight element 113. For example, the base plate surface 310a of the rear portion 310 can contact or directly contact the reflector 113b of the backlight element 113.

[0312] Side portion 330 may be configured to support guide member 115 of vibration member 100. The side surface of side portion 330 may be surrounded by guide side portion 115b of guide member 115. Therefore, vibration of vibration device 500 can be transmitted to guide member 115 via side portion 330 of support member 300, and can be transmitted to peripheral portion of display panel 111 via connecting member 114. For example, side portion 330 may be a sidewall portion or a side cover portion, and embodiments of this disclosure are not limited thereto.

[0313] The curved portion 350 can be implemented at the rear portion 310. The curved portion 350 can be referenced above. Figure 3 and Figures 4A to 4C The descriptions are the same or substantially the same, therefore, for the sake of brevity, repeated descriptions can be omitted.

[0314] The device 1 according to the first embodiment of the present disclosure may further include a gap space GS between the curved portion 350 of the support member 300 and the vibrating member 100.

[0315] The gap space GS can be disposed between the curved portion 350 of the support member 300 and the rear surface of the vibrating member 100. For example, the gap space GS can be disposed between the curved portion 350 and the reflector 113b of the backlight member 113. The gap space GS can include a space for generating sound or sound pressure level based on the vibration of the curved portion 350, a space for smoothly performing the vibration of the curved portion 350, or a space for sound waves generated by the vibration of the vibrating device 500 to propagate to the vibrating member 100. For example, the gap space GS can be an air gap, a sound pressure level generating space, a sound space, a sound pressure level space, a sound-emitting part, a resonance box, a sound wave propagation path, a sound energy incident part, or a sound path, but the embodiments of this disclosure are not limited thereto.

[0316] The vibration device 500 can be disposed at or connected to the curved portion 350. For example, the vibration device 500 can be disposed at or connected to the rear surface of the curved portion 350. The vibration device 500 disposed at or connected to the curved portion 350 may include a first vibration device 500-1 and a second vibration device 500-2, and may be consistent with the description above. Figures 2 to 4C The descriptions are the same or substantially the same, therefore, for the sake of brevity, repeated descriptions can be omitted.

[0317] The vibration device 500 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape. Therefore, the vibration device 500 can be configured to vibrate the curved portion 350 to vibrate the vibration member 100 based on the vibration of the curved portion 350, thereby generating or outputting sound and / or tactile feedback. For example, the vibration device 500 can vibrate based on a drive signal to vibrate the curved portion 350. Therefore, the sound (or sound wave) generated based on the vibration of the curved portion 350 can be output to the gap space GS. The sound generated by the vibration of the backlight member 113 based on the sound of the gap space GS can be transmitted to the sound transmission space STS, and sound and / or tactile feedback can be generated by the vibration of the display panel 111 based on the sound of the sound transmission space STS.

[0318] Therefore, the device 1 according to the first exemplary embodiment of the present disclosure may include a vibration device 500 that vibrates in a state where the vibration device 500 receives prestress (or pretension) or is bent into a curved shape. Therefore, the second moment of inertia may be increased, or the vibration direction of the vibration device 500 may be realized as a single direction, thereby enhancing the acoustic characteristics and / or sound pressure level characteristics of the sound generated by the vibration member 100 vibrating based on the vibration of the vibration device 500.

[0321] The vibration generator 510 can vibrate (or displace) based on a drive signal (or electrical signal or voice signal) applied thereto, so as to cause the vibrating member 100 to vibrate (or displace). For example, the vibration generator 510 may be referred to as a vibration device, vibration structure, vibrator, vibration generating device, sound generator, sound device, sound generating structure or sound generating device, but the embodiments of this disclosure are not limited thereto.

[0322] The vibration generator 510 according to an exemplary embodiment of this disclosure may include a piezoelectric material (or electroactive material) having piezoelectric properties. The vibration generator 510 may autonomously vibrate (or displace) based on the vibration (or displacement) of the piezoelectric material generated by a driving signal applied thereto, or it may cause the vibration member 100 to vibrate (or displace). For example, the vibration generator 510 may vibrate (or displace) when alternately contracting and / or expanding by the piezoelectric effect (or piezoelectric properties). For example, the vibration generator 510 may vibrate (or displace) in the vertical direction (or thickness direction) Z when alternately contracting and / or expanding by the inverse piezoelectric effect.

[0323] The vibration generator 510 can be configured to be flexible. For example, the vibration generator 510 can be configured to bend into a non-planar shape including a curved surface.

[0324] The vibration generator 510 according to an exemplary embodiment of this disclosure may include a quadrilateral shape having a first length parallel to a first direction X and a second length parallel to a second direction Y intersecting the first direction X. For example, the vibration generator 510 may include a square shape with the first length and the second length being the same, or it may include a rectangular shape with the first length and the second length being different. For example, a vibration device including a vibration generator 510 with a square shape may be coupled to or attached to... Figure 4A The bending portion 350 of the support member 300 shown. For example, a vibration device including a vibration generator 510 with a rectangular shape can be coupled to or attached to.

[0325] The connecting member 520 may be connected to or coupled to one of the first surface S1 and the second surface S2 of the vibration generator 510, wherein the second surface S2 is different from (or opposite to) the first surface S1. For example, in the vibration generator 510, the first surface S1 may be a top surface, a forward surface, a front surface, or an upper surface. In the vibration generator 510, the second surface S2 may be a bottom surface, a back surface, a rear surface, a lower surface, or a rearward surface. For example, in the vibration generator 510, the first surface S1 may be positioned closer to the connecting member 520 than the second surface S2. For example, the connecting member 520 may be a first connecting member, an adhesive member, or a first adhesive member.

[0326] According to an exemplary embodiment of this disclosure, the connecting member 520 may include an adhesive layer (or sticky layer) with good adhesion or bonding strength. For example, the connecting member 520 may include double-sided tape, double-sided foam pad, or adhesive sheet. For example, when the connecting member 520 includes an adhesive sheet (or adhesive layer), the connecting member 520 may include only the adhesive layer or sticky layer, without including a base component such as a plastic material.

[0327] The adhesive layer (or adhesive layer) of the connecting member 520 according to an exemplary embodiment of the present disclosure may include epoxy resin, acrylic resin, silicone resin, or polyurethane, but the embodiments of the present disclosure are limited thereto. The adhesive layer (or adhesive layer) of the connecting member 520 according to another exemplary embodiment of the present disclosure may include pressure-sensitive adhesive (PSA), optically clear adhesive (OCA), or optically clear resin (OCR), but the embodiments of the present disclosure are not limited thereto.

[0328] like Figure 3 and Figure 5 As shown, according to an exemplary embodiment of the present disclosure, the connecting member 520 can connect or couple the vibration generator 510 to the curved portion 350 of the support member 300. For example, the connecting member 520 can be disposed between the curved portion 350 of the support member 300 and the first surface of the vibration generator 510. For example, the connecting member 520 can be inserted between the curved portion 350 of the support member 300 and the first surface of the vibration generator 510.

[0329] Therefore, the vibration generator 510 can be connected to or attached to the curved portion 350 of the support member 300 via the connecting member 520, and thus can receive prestress (or pretension), or can include a state in which the vibration generator 510 is bent into a curved shape based on the bending shape of the curved portion 350. Therefore, the vibration generator 510 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape, and thus, as described above, the second moment of inertia can be increased, or the vibration direction can be realized in a single direction.

[0330] Figure 7 This is a perspective view illustrating a vibration device according to a second exemplary embodiment of the present disclosure. Figure 7 Example of adding pad blocks Figure 6 An example implementation of the vibration device shown.

[0331] Reference Figure 7 The vibration device 500 or the first vibration device 500-1 and the second vibration device 500-2 according to the second exemplary embodiment of the present disclosure may include a vibration generator 510, a connecting member 520 and a pad 530.

[0332] Each of the vibration generator 510 and the connecting member 520 can be referenced above. Figure 6 The descriptions are the same or substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0333] The pad 530 may be attached to or attached to the second surface of the vibration generator 510. For example, the pad 530 may be attached to or attached to the central portion of the second surface of the vibration generator 510. The pad 530 may have a size smaller than or equal to the size of the vibration generator 510. For example, the pad 530 may have a polygonal column shape or a cylindrical shape, but embodiments of this disclosure are not limited thereto.

[0334] The pad 530 according to an exemplary embodiment of the present disclosure may include a material with a stiffness less than the bending stiffness of the vibration generator 510. The pad 530 according to another exemplary embodiment of the present disclosure may include an elastic material that can be used as mass (or weight) on the vibration generator 510.

[0335] The pad 530 according to an exemplary embodiment of this disclosure can increase the mass of the vibration generator 510, thereby reducing the lowest resonant frequency (or lowest natural frequency) of the vibration generator 510. Therefore, the vibration generator 510 can vibrate at a relatively low frequency due to the increase in the lowest resonant frequency (or lowest natural frequency) caused by the mass increase from the pad 530. Thus, the sound characteristics and / or sound pressure level characteristics of the bass vocal cords generated by the vibration of the vibration device 500 can be enhanced. For example, the pad 530 can be a resonant pad, a mass member, a weight clapper, or a counterweight. For example, the bass vocal cords can be approximately 300 Hz or approximately 500 Hz or lower, but embodiments of this disclosure are not limited thereto.

[0336] Figure 8 This is a perspective view illustrating a vibration device according to a third exemplary embodiment of the present disclosure. Figure 8 An example is shown of adding a plate and a second connecting member. Figure 6 An example embodiment of the vibration device is shown. Therefore, in the description... Figure 8 For the sake of brevity, only the plate, the second connecting member, and related components will be described.

[0337] Combination Figure 3 or Figure 5 Reference Figure 8 The vibration device 500 or the first vibration device 500-1 and the second vibration device 500-2 according to the third exemplary embodiment of the present disclosure may include a vibration generator 510, a first connecting member 520, a plate 540 and a second connecting member 550.

[0338] Each of the vibration generator 510 and the first connecting member 520 can be referenced above. Figure 6 The descriptions are the same or substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0339] Plate 540 can be attached to or attached to the first connecting member 520. For example, plate 540 can have a size or area larger than that of the vibration generator 510. For example, the central portion of plate 540 can be aligned with or located at the central portion of the vibration generator 510. Plate 540 can be connected to or attached to the second connecting member 550. Figures 2 to 6 On the curved portion 350 of the support member 300 shown.

[0340] According to an exemplary embodiment of this disclosure, the vibration generator 510 may have a modulus greater than that of each of the first connecting member 520, the plate 540, and the second connecting member 550, or it may have a modulus equal to that of each of the first connecting member 520 and the second connecting member 550 and greater than that of the plate 540, thereby bending the vibration generator 510 into a curved shape, and transmitting the vibration of the vibration generator 510 to the curved portion 350 of the support member 300. For example, the plate 540 may have a modulus smaller than that of the vibration generator 510. Therefore, the vibration generator 510 can be bent into a shape corresponding to the curved portion 350 of the support member 300 by the first connecting member 520, the plate 540, and the second connecting member 550, thereby enhancing the reliability of sound reproduction. Furthermore, the vibration generator 510 according to an exemplary embodiment of the present disclosure may have enhanced adhesion to the curved portion 350 of the support member 300 via the first connecting member 520, the plate 540 and the second connecting member 550, and vibration can be transmitted to the curved portion 350 of the support member 300 without vibration loss, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords.

[0341] For example, when the modulus of plate 540 is greater than that of vibration generator 510, vibration generator 510 may be difficult to bend into the shape corresponding to the curved portion 350 of support member 300, and the adhesion of the curved portion 350 of support member 300 via first connecting member 520, plate 540 and second connecting member 550 may be reduced. Therefore, the reliability of sound reproduction may be reduced, and the sound characteristics and / or sound pressure level characteristics of the bass vocal cords may be reduced. According to an exemplary embodiment of this disclosure, plate 540 may comprise a material with material properties suitable for bending vibration generator 510 into a curved shape and for the vibration of vibration generator 510 to be transmitted to the curved portion 350 of support member 300. For example, plate 540 may comprise a material with a stiffness less than the bending stiffness of vibration generator 510. Plate 540 may comprise one or more materials such as metal, glass, plastic, fiber, leather, rubber, wood, cloth and paper. For example, plate 540 may be a support plate, rigid plate, transmission plate, intermediate plate or vibration transmission plate, but embodiments of this disclosure are not limited thereto. Figure 8 The second connecting member 550 shown can connect or attach the plate 540 to... Figure 3 and Figure 5 The bending portion 350 of the support member 300 shown. For example, a second connecting member 550 may be disposed between the bending portion 350 of the support member 300 and the plate 540. For example, the second connecting member 550 may be inserted between the bending portion 350 of the support member 300 and the plate 540.

[0342] The second connecting member 550 may include an adhesive layer (or sticky layer) with good adhesion or bonding strength. The second connecting member 550 may include an adhesive material having a modulus different from that of the first connecting member 520. For example, the first connecting member 520 may have a modulus (or adhesive strength or hardness) greater than that of the second connecting member 550, such that the plate 540 and the vibration generator 510 can be smoothly bent into a curved shape.

[0343] Therefore, the vibration generator 510 can be connected to or attached to the curved portion 350 of the support member 300 via the first connecting member 520, and thus can receive prestress (or pretension), or can include a state in which the vibration generator 510 is bent into a curved shape based on the bending shape of the curved portion 350. Therefore, the vibration generator 510 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape, thus the second moment of inertia can be increased, or the vibration direction can be realized in a single direction.

[0344] Figure 9 This is a perspective view illustrating a vibration device according to a fourth exemplary embodiment of the present disclosure. Figure 9 Example of adding pad blocks Figure 8 An example implementation of the vibration device shown.

[0345] Reference Figure 9 The vibration device 500 or the first vibration device 500-1 and the second vibration device 500-2 according to the fourth exemplary embodiment of this disclosure may include a vibration generator 510, a first connecting member 520, a plate 540, a second connecting member 550 and a pad 530.

[0346] Each of the vibration generator 510, the first connecting member 520, the plate 540, and the second connecting member 550 can be referred to above. Figure 8 The descriptions are the same or substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0347] The spacer 530 can be attached to or attached to the second surface of the vibration generator 510. For example, the spacer 530 can be attached to or attached to the central portion of the second surface of the vibration generator 510. The spacer 530 can increase the mass of the vibration generator 510 to lower the lowest resonant frequency (or lowest natural frequency) of the vibration generator 510. The spacer 530 can be referenced above. Figure 7 The descriptions are essentially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0348] Figure 10 It is along Figure 2 Another example cross-sectional view taken from line II-II' shown. Figure 10 Examples are given of the direction Figures 2 to 9 The example embodiment of device 1 shown here has an added casing. Therefore, in the description Figure 10 In this case, other components besides the housing and related elements are indicated by similar reference numerals, and their repeated descriptions may be omitted for the sake of brevity.

[0349] Reference Figure 10 The device 1 according to the first exemplary embodiment of this disclosure may further include a housing 950.

[0350] The housing 950 may be connected to or coupled to the rear surface of the support member 300 to cover the vibrating device 500. For example, the housing 950 may be connected to or coupled to the rear surface of the rear portion 310 of the support member 300 via a connecting member 951. The housing 950 may form an enclosed space in the rear surface of the support member 300 that covers or surrounds the vibrating device 500. For example, the housing 950 may form an enclosed space in the rear surface of the rear portion 310 of the support member 300 that covers or surrounds the vibrating device 500. For example, the housing 950 may be an enclosing member, an enclosing cover, an enclosing box, or a speaker enclosure, but embodiments of this disclosure are not limited thereto. The enclosed space may be an air gap, a vibration space, a sound space, or a resonating chamber, but embodiments of this disclosure are not limited thereto.

[0351] The housing 950 may comprise one or more materials, including metallic materials and non-metallic materials (or composite non-metallic materials). For example, the housing 950 may comprise one or more materials selected from metallic materials, plastics, and wood, but the embodiments disclosed herein are not limited thereto.

[0352] When the curved portion 350 of the support member 300 or the vibrating device 500 vibrates, the housing 950 according to an exemplary embodiment of the present disclosure can retain the air-based impedance component acting on the curved portion 350 of the support member 300. For example, the air surrounding the support member 300 can resist the vibration of the curved portion 350 of the support member 300 and can be used as an impedance component having a frequency-based inductive resistance component and a drag component. Therefore, the housing 950 can be constructed in the rear surface of the support member 300 to form an enclosed space surrounding the vibrating device 500, thereby retaining the air-based impedance component (or air impedance or elastic impedance) acting on the curved portion 350 of the support member 300, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal bands and enhancing the sound quality of the high-pitched vocal bands. For example, the high-pitched vocal bands may be 3 kHz or higher or 5 kHz or higher, but the embodiments of the present disclosure are not limited thereto.

[0353] In the device 1 according to the first exemplary embodiment of the present disclosure, the housing 950 can enhance the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords and enhance the sound quality of the high-pitched vocal cords.

Figure 11A and Figure 11B Examples are shown by modifying Figures 2 to 5 An example implementation is achieved by bending the support member shown.

[0355] Reference Figure 11A and Figure 11B According to another exemplary embodiment of the present disclosure, the rear portion 310 of the support member 300 may include a first region 300A1, a second region 300A2, and a third region 300A3. For example, relative to a first length (or width direction length) parallel to the first direction X, the rear portion 310 of the support member 300 may include the first region 300A1, the second region 300A2, and the third region 300A3.

[0356] The first region 300A1 can be a first rear region, a left region, or a left rear region. The second region 300A2 can be a second rear region, a right region, or a right rear region. The third region 300A3 can be the region between the first region 300A1 and the second region 300A2. For example, the third region 300A3 can be the central region including the support member 300 and a centerline having a first length.

[0357] The support member 300 may include a curved portion 350 disposed in each of the first region 300A1, the second region 300A2 and the third region 300A3.

[0359] Each of the first curved portion 350a, the second curved portion 350b, and the third curved portion 350c may protrude from the rear portion 310 to have the same size and shape. Each of the first curved portion 350a, the second curved portion 350b, and the third curved portion 350c may protrude from the rear portion 310 to have the same curvature. The protruding structure and curvature of each of the first curved portion 350a, the second curved portion 350b, and the third curved portion 350c may be referenced above. Figure 3 The descriptions are the same or substantially the same, therefore, for the sake of brevity, repeated descriptions can be omitted.

[0360] As mentioned above Figures 4A to 4C Each of the first curved portion 350a, the second curved portion 350b, and the third curved portion 350c may have a square or rectangular shape, and therefore, repeated descriptions of them may be omitted for the sake of brevity.

[0361] The vibration device 500 may include a first vibration device 500-1 disposed at a first curved portion 350a, a second vibration device 500-2 disposed at a second curved portion 350b, and a third vibration device 500-3 disposed at a third curved portion 350c. As described above, each of the first vibration device 500-1, the second vibration device 500-2, and the third vibration device 500-3 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape. Therefore, as described above, the second moment of inertia can be increased, or the vibration direction can be realized in a single direction.

[0362] Reference Figure 11B According to an exemplary embodiment of this disclosure, one or more of the first curved portion 350a, the second curved portion 350b, and the third curved portion 350c may protrude from the rear portion 310 with different sizes and different shapes. One or more of the first curved portion 350a, the second curved portion 350b, and the third curved portion 350c may protrude from the rear portion 310 with different curvatures. For example, the third curved portion 350c may have a smaller size than each of the first curved portion 350a and the second curved portion 350b. Besides the fact that the third curved portion 350c has a smaller size than each of the first curved portion 350a and the second curved portion 350b, Figure 11B The curved portion 350 shown may be substantially the same, so for the sake of brevity, its repeated description can be omitted.

[0363] The third vibration device 500-3 can be located at the third bending portion 350c and can have a size corresponding to the size of the third bending portion 350c. Therefore, the third vibration device 500-3 can have a smaller size than each of the first vibration device 500-1 and the second vibration device 500-2.

[0364] Reference Figure 11A and Figure 11B Each of the first vibration device 500-1, the second vibration device 500-2, and the third vibration device 500-3 according to an exemplary embodiment of the present disclosure can be configured to generate or output the same pitch of the vocal cords. Therefore, the device 1 according to an exemplary embodiment of the present disclosure can output stereo sound based on the vibration of the vibrating member 100 based on the vibration of each of the first vibration device 500-1, the second vibration device 500-2, and the third vibration device 500-3, and can have 3-channel sound output characteristics.

[0365] According to another exemplary embodiment of this disclosure, one or more of the first vibration device 500-1, the second vibration device 500-2, and the third vibration device 500-3 can be configured to generate or output sounds with different pitches. For example, the third vibration device 500-3 can be configured to generate or output sounds with lower pitches, and each of the first vibration device 500-1 and the second vibration device 500-2 can be configured to generate or output sounds with pitches wider than those of the third vibration device 500-3, but the embodiments of this disclosure are not limited thereto. Therefore, the device 1 according to the first exemplary embodiment of this disclosure can achieve sound, for example, stereo sound by outputting left and right sounds based on the vibration of the driven vibrating member 100 of each of the first vibration device 500-1 and the second vibration device 500-2, and the sound characteristics and / or sound pressure level characteristics of the lower pitches can be enhanced due to the lower pitches output based on the vibration of the driven vibrating member 100 of the third vibration device 500-3.

[0366] Figure 12 It is along Figure 2 Another example cross-sectional view taken from line II-II' shown. Figure 13 This is an example Figure 12 Example rear perspective view of the support member shown. Figure 14 This is an example Figure 13 Example rear view of the support member shown. Figures 12 to 14 Examples are shown in the reference above. Figures 1 to 5 An example embodiment of the described device involves adding holes to the curved portion of a support member.

[0367] Reference Figures 12 to 14 According to a second exemplary embodiment of the present disclosure, the device 2 may include a vibration member 100, a support member 300, and a vibration device 500.

[0368] Vibrating component 100 can be referred to above. Figures 1 to 5 The descriptions are the same or substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0369] The support member 300 can be configured to support the vibration member 100. The support member 300 may include a rear portion 310, a side portion 330, a curved portion 350, and a hole 360. Each of the rear portion 310 and the side portion 330 may be referenced above. Figures 3 to 5 Each of the rear portion 310 and the side portion 330 described is identical or substantially identical, therefore, repeated descriptions may be omitted for brevity. Furthermore, except that the curved portion 350 includes the hole 360, the curved portion 350 may be the same as described above. Figures 3 to 5The described curved portion 350 is the same or substantially the same. Therefore, for the sake of brevity, its repeated description can be omitted.

[0370] The support member 300 may also include one or more holes 360 formed at the bend 350. The support member 300 may include one or more holes 360 formed at each of the first bend 350a and the second bend 350b.

[0371] One or more holes 360 may be formed at the curved portion 350. For example, one or more holes 360 may be formed to pass through the curved portion 350 along a third direction Z. Therefore, one or more holes 360 may be an opening, a connecting portion, an opening hole, a connecting hole, a through portion, a through port, a through hole, a support hole, a slit, a slot, or a sound passage portion, but the embodiments of this disclosure are not limited thereto. For example, the third direction Z may be the thickness direction or the height direction of the support member 300, or it may be the Z-axis direction in the XYZ axis direction.

[0372] According to an exemplary embodiment of this disclosure, one or more holes 360 may be formed in a portion (or central portion) of the curved portion 350 other than the peripheral portion. For example, one or more holes 360 may be formed to pass through a portion (or central portion) of the curved portion 350 in a third direction Z. For example, a support member 300 may include one or more holes 360 formed in a portion (or central portion) of the curved portion 350 other than the peripheral portion.

[0373] One or more holes 360 may be formed at the curved portion 350 and may have the same shape as the vibrating device 500. For example, when the vibrating device 500 has a square shape, one or more holes 360 may have a square shape, and when the vibrating device 500 has a rectangular shape, one or more holes 360 may have a rectangular shape, but the embodiments of this disclosure are not limited thereto.

[0374] One or more holes 360 may be formed at each of the first curved portion 350a and the second curved portion 350b. The size of one or more holes 360 may be smaller than the size of each of the first vibrating device 500-1 and the second vibrating device 500-2. For example, when the total size (or total width) of one or more holes 360 is greater than the total size of the first vibrating device 500-1 and the second vibrating device 500-2, the first vibrating device 500-1 and the second vibrating device 500-2 may be inserted into (or pass through or be accommodated in) one or more holes 360, and therefore, without additional mechanisms, the first vibrating device 500-1 and the second vibrating device 500-2 may not be provided at the curved portion 350. Therefore, when the total size (or total width) of one or more holes 360 is smaller than the total size of the first vibration device 500-1 and the second vibration device 500-2, the first vibration device 500-1 and the second vibration device 500-2 can be arranged at the curved portion 350 to cover one or more holes 360 or overlap with one or more holes 360 without additional mechanisms.

[0375] One or more holes 360 formed at each of the first curved portion 350a and the second curved portion 350b can be provided between the vibrating member 100 and the first vibrating device 500-1 and the second vibrating device 500-2. Therefore, one or more holes 360 can provide a clearance space GS between the vibrating member 100 and the first vibrating device 500-1 and the second vibrating device 500-2. Therefore, with... Figure 5 Compared to the device 1 shown, the gap space GS between the vibrating member 100 and the first curved portion 350a and the second curved portion 350b can extend to a space corresponding to the thickness of the first curved portion 350a and the second curved portion 350b. For example, the gap space GS can be an air gap, a sound pressure level generating space, a sound space, a sound pressure level space, a sound-generating portion, a resonating box, a sound wave propagation path, a sound energy incident portion, or a sound path, but the embodiments of this disclosure are not limited thereto.

[0376] One or more holes 360 formed in each of the first curved portion 350a and the second curved portion 350b can be provided between the backlight member 113 of the vibrating member 100 and the first vibrating device 500-1 and the second vibrating device 500-2. Therefore, one or more holes 360 can provide a gap space GS between the backlight member 113 and the first vibrating device 500-1 and the second vibrating device 500-2. For example, one or more holes 360 can provide a gap space GS between the reflective sheet 113b of the backlight member 113 and the first vibrating device 500-1 and the second vibrating device 500-2.

[0377] Each of the first vibration device 500-1 and the second vibration device 500-2 of the vibration device 500 can be connected to or attached to the first bending portion 350a and the second bending portion 350b to cover one or more holes 360, and can vibrate in a state where the first vibration device 500-1 and the second vibration device 500-2 receive prestress (or pretension) or are bent into a bending shape, so that the second moment of inertia can be increased, or the vibration direction can be realized as a single direction.

[0378] Each of the first vibration device 500-1 and the second vibration device 500-2 of the vibration device 500 can face or directly face the rear surface of the vibration member 100 through one or more holes 360. For example, each of the first vibration device 500-1 and the second vibration device 500-2 can face or directly face the backlight member 113 of the vibration member 100 through one or more holes 360. For example, each of the first vibration device 500-1 and the second vibration device 500-2 can face or directly face the reflector 113b of the backlight member 113 through one or more holes 360. Therefore, sound (or sound waves) generated by the driving of each of the first vibration device 500-1 and the second vibration device 500-2 can be directly transmitted to the vibration member 100 through one or more holes 360 or the gap space GS. For example, sound (or sound waves) generated by the driving of each of the first vibration device 500-1 and the second vibration device 500-2 can be directly transmitted to the backlight 113 of the vibrating member 100 through one or more holes 360 or gap spaces GS. Therefore, the vibration of each of the first vibration device 500-1 and the second vibration device 500-2 can be effectively transmitted to the vibrating member 100, thereby enhancing the sound characteristics and / or sound pressure level characteristics generated by the vibration of the vibrating member 100. For example, each of the first vibration device 500-1 and the second vibration device 500-2 can vibrate based on a driving signal to output sound (or sound waves) to the gap space GS; sound generated by the vibration of the backlight 113 based on the sound in the gap space GS can be output to the sound transmission space STS; and sound and / or tactile feedback can be generated based on the vibration of the display panel 111 based on the sound in the gap space GS.

[0379] The device 2 according to the second exemplary embodiment of this disclosure can vibrate in a state where the vibrating device 500 receives prestress (or pretension) or is bent into a curved shape. Therefore, the second moment of inertia in the vibrating device 500 can be increased, or the vibration direction of the vibrating device 500 can be realized as a single direction. Therefore, the sound characteristics and / or sound pressure level characteristics generated by the vibration of the vibrating member 100 based on the vibration of the vibrating device 500 can be enhanced. In addition, the device 2 according to the second exemplary embodiment of this disclosure may include a hole 360 ​​formed in the curved portion 350 of the support member 300. Therefore, the sound (or sound wave) generated based on the vibration of the vibrating device 500 can be directly transmitted to the vibrating member 100. Therefore, the vibration transmission efficiency can be increased, and the sound characteristics and / or sound pressure level characteristics generated based on the vibration of the vibrating member 100 can be further enhanced.

[0380] The device 2 according to the second exemplary embodiment of this disclosure may further include a housing 950.

[0381] The housing 950 may be disposed on the rear surface of the vibrating device 500. For example, the housing 950 may be connected to or coupled to the rear surface of the support member 300 to cover the vibrating device 500. For example, the housing 950 may be connected to or coupled to the rear surface of the rear portion 310 of the support member 300 via a connecting member 951. The housing 950 may construct (or form) an enclosed space covering or surrounding the vibrating device 500 in the rear surface of the rear portion 310 of the support member 300. For example, the housing 950 may construct an enclosed space covering or surrounding the vibrating device 500 in the rear surface of the rear portion 310 of the support member 300. For example, the housing 950 may be a sealing member, a sealing cover, a sealing box, or a speaker enclosure, but embodiments of the present disclosure are not limited thereto.

[0383] When the vibrating device 500 vibrates, the housing 950 according to an exemplary embodiment of this disclosure can retain the impedance component based on the air acting on the vibrating device 500. For example, the air surrounding the vibrating device 500 can resist the vibration of the vibrating device 500 and can be used as an impedance component having a frequency-based induced resistance component and a drag component. Therefore, the housing 950 can be constructed in the rear surface of the support member 300 to form an enclosed space surrounding the vibrating device 500, thus retaining the impedance component (or air impedance or elastic impedance) based on the air acting on the vibrating device 500. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be enhanced, and the sound quality of the high-pitched vocal cords can be enhanced.

[0430] According to another exemplary embodiment of this disclosure, the vibration device 500 can be compared with the above-described embodiment. Figures 4A to 9 The described vibration equipment 500 is the same or substantially the same, therefore, for the sake of brevity, its repeated description can be omitted.

[0431] According to another exemplary embodiment of this disclosure, the vibration device (or vibration generator) 500 may be coupled to or attached to the bending portion 350, and thus may have or receive prestress based on the bending portion 350. For example, the vibration device 500 may be coupled to or attached to the bending portion 350, and thus may be maintained in a state where the vibration device 500 has or receives prestress based on the bending portion 350. For example, the vibration device 500 may receive tensile stress or include tensile stress based on the curvature of the bending portion 350. For example, the bending portion 350 may be implemented to apply only tensile stress to the vibration device 500 to enhance the vibration characteristics of the vibration device 500.

[0432] According to another exemplary embodiment of this disclosure, as referred to above... Figure 3 The vibration device 500 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape based on the bending portion 350 realized at the protruding portion 340. Therefore, as described above, the second moment of inertia can be increased, or the vibration direction can be realized in a single direction. Therefore, for the sake of brevity, repeated descriptions can be omitted.

[0433] The vibration device 500 may include a first vibration device 500-1 and a second vibration device 500-2. The first vibration device 500-1 and the second vibration device 500-2 may refer to the above description.

The first vibration device 500-1 can be coupled to or attached to the first curved portion 350a between the vibration member 100 and the first curved portion 350a, and can face or directly face the rear surface of the vibration member 100.

Therefore, the first vibration device 500-1 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape based on the first curved portion 350a, and thus, sound or sound waves can be generated. The sound (or sound waves) generated by the vibration of the first vibration device 500-1 can be directly transmitted to the vibrating member 100 through the gap space GS, so the vibration of the first vibration device 500-1 can be effectively transmitted to the vibrating member 100, thereby enhancing the sound characteristics and / or sound pressure level characteristics generated by the vibration of the vibrating member 100. For example, the first region of the vibrating member 100 that overlaps with the first vibrating device 500-1 can vibrate based on receiving sound or sound waves generated by the vibration of the first vibrating device 500-1, and thus can generate or output sound and / or tactile feedback.

For example, the second vibration device 500-2 can be coupled to or attached to the inner surface (or inner curved surface) of the second curved portion 350b within the gap space GS.

[0437] The second vibration device 500-2 (or vibration generator) can be coupled to or attached to the second curved portion 350b to have an isoangular shape based on the curvature of the second curved portion 350b, but the embodiments of this disclosure are not limited thereto. For example, the second vibration device 500-2 can be coupled to or attached to the second curved portion 350b to have a non-isoangular shape not based on the curvature of the second curved portion 350b or having a curvature different from the curvature of the second curved portion 350b. Therefore, the second vibration device 500-2 can vibrate in a state where it receives prestress (or pretension) or is bent into a curved shape based on the second curved portion 350b, and thus, sound or sound waves can be generated. The sound (or sound waves) generated by the vibration of the second vibration device 500-2 can be directly transmitted to the vibrating member 100 through the gap space GS. Therefore, the vibration of the second vibration device 500-2 can be effectively transmitted to the vibrating member 100, thereby enhancing the sound characteristics and / or sound pressure level characteristics generated by the vibration of the vibrating member 100. For example, the second region of the vibrating member 100 that overlaps with the second vibrating device 500-2 can vibrate based on receiving sound or sound waves generated by the vibration of the second vibrating device 500-2, and thus can generate or output sound and / or tactile feedback.

[0438] The device 3 according to the third exemplary embodiment of this disclosure may include a vibration device 500 (or vibration generator) that vibrates while receiving prestress (or tensile stress) or bent into a curved shape. Therefore, the second moment of inertia can be increased, or the vibration direction of the vibration device 500 can be made unidirectional, thereby enhancing the acoustic characteristics and sound pressure level characteristics of the sound generated by the vibrating member 100 vibrating based on the vibration of the vibration device 500. Furthermore, because the vibration device 500 is disposed in the gap space GS between the vibrating member 100 and the support member 300, the device 3 according to the third exemplary embodiment of this disclosure can be thinned, and in this example, the vibration device 500 is not exposed to the outside, thereby enhancing the aesthetic design of the outermost rear surface. The device 3 according to the third embodiment of this disclosure may also include a housing 950.

[0439] The housing 950 may be configured to cover the protruding portion 340 and the bent portion 350 of the support member 300. The housing 950 may be connected to or coupled to the rear surface of the support member 300 to cover the protruding portion 340 and the bent portion 350. For example, the housing 950 may be connected to or coupled to the rear surface of the rear portion 310 of the support member 300 via a connecting member 951. The housing 950 may form an enclosed space in the rear surface of the support member 300 that covers or surrounds the vibrating device 500. For example, the housing 950 may be an enclosing member, an enclosing cover, an enclosing box, or a speaker enclosure, but embodiments of this disclosure are not limited thereto. The enclosed space may be an air gap, a vibration space, a sound space, or a resonating chamber, but embodiments of this disclosure are not limited thereto.

[0440] The housing 950 may comprise one or more materials, including metallic materials and non-metallic materials (or composite non-metallic materials). For example, the housing 950 may comprise one or more materials selected from metallic materials, plastics, and wood, but the embodiments disclosed herein are not limited thereto.

[0441] When the curved portion 350 of the support member 300 or the vibrating device 500 vibrates, the housing 950 according to an exemplary embodiment of the present disclosure can retain the impedance component acting on the curved portion 350 of the support member 300 based on air. For example, the air surrounding the support member 300 can resist the vibration of the curved portion 350 of the support member 300 and can be used as an impedance component having a frequency-based induced resistance component and a drag component. Therefore, the housing 950 can form an enclosed space around the protrusion 340 and the curved portion 350 of the support member 300 in the rear surface of the support member 300, thus retaining the impedance component (or air impedance or elastic impedance) acting on the curved portion 350 of the support member 300 based on air. Therefore, the sound characteristics and sound pressure level characteristics of the low-pitched vocal cords can be enhanced, and the sound quality of the high-pitched vocal cords can be enhanced.

[0442] In the device 3 according to the third exemplary embodiment of the present disclosure, the housing 950 can enhance the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords and enhance the sound quality of the high-pitched vocal cords.

Furthermore, except that the curved portion 350 includes the hole 360, the curved portion 350 may be the same as described above.

Therefore, the vibration (or displacement) of each of the first vibration device 500-1 and the second vibration device 500-2 can be performed smoothly, thus increasing the vibration width (or displacement width) of each of the first vibration device 500-1 and the second vibration device 500-2. Therefore, the sound pressure level generated in the gap space GS based on the vibration of each of the first vibration device 500-1 and the second vibration device 500-2 can be increased, thus increasing the vibration width (or displacement width) of the vibrating member 100 vibrating based on the sound pressure level of the gap space GS. Therefore, the sound characteristics and / or sound pressure level characteristics generated based on the vibration of the vibrating member 100 can be enhanced.

[0449] The device 4 according to the fourth exemplary embodiment of this disclosure may include a vibration device (or vibration generator) 500 that vibrates in a state where it receives prestress (or pretension) or is bent into a curved shape. Therefore, the second moment of inertia can be increased, or the vibration direction of the vibration device 500 can be made unidirectional, thereby enhancing the acoustic characteristics and / or sound pressure level characteristics of the sound generated by the vibrating member 100 vibrating based on the vibration of the vibration device 500. Additionally, the device 4 according to the fourth exemplary embodiment of this disclosure may include one or more holes 360 formed in the curved portion 350 of the support member 300. Therefore, the vibration of the vibration device 500 can be performed more smoothly, thereby increasing the vibration width (or displacement width) of each of the first vibration device 500-1 and the second vibration device 500-2. Therefore, the vibration width (or displacement width) of the vibrating member 100 can be increased, and thus, the acoustic characteristics and / or sound pressure level characteristics generated based on the vibration of the vibrating member 100 can be further enhanced.

[0450] The device 4 according to the fourth exemplary embodiment of this disclosure may further include a housing 950. The housing 950 may be referenced above.

[0484] Each of the plurality of first portions 511a1 can be configured as a ceramic matrix material for generating relatively high vibrations, or can be configured as a piezoelectric ceramic having a perovskite crystal structure. The perovskite crystal structure can exhibit both piezoelectric and inverse piezoelectric effects, and can be an oriented structure. The perovskite crystal structure can be represented by the chemical formula "ABO3". In the chemical formula, "A" can include a divalent metal element, and "B" can include a tetravalent metal element. For example, in the chemical formula "ABO3", "A" and "B" can be cations, and "O" can be an anion. For example, each of the plurality of first portions 511a1 can include at least one or more of lead(II) titanate (PbTiO3), lead zirconate (PbZrO3), lead zirconate titanate (PbZrTiO3), barium titanate (BaTiO3), and strontium titanate (SrTiO3), but embodiments of this disclosure are not limited thereto.

[0485] In perovskite crystal structures containing a central ion (e.g., PbTiO3), the position of titanium (Ti) ions can change due to external stress or magnetic fields. Therefore, polarization can change, resulting in a piezoelectric effect. For example, in a perovskite crystal structure, a cubic shape corresponding to a symmetrical structure can be transformed into a tetragonal (e.g., quadrilateral), square, or rhombohedral structure corresponding to an asymmetrical structure, thus generating a piezoelectric effect. In tetragonal (e.g., quadrilateral), square, or rhombohedral structures corresponding to asymmetrical structures, the polarizability at the quasi-isomorphic phase boundaries can be high, and the polarization can easily rearrange, thus the perovskite crystal structure may possess high piezoelectric properties.

[0486] The vibrating layer 511a or the first portion 511a1 according to the exemplary embodiments of this disclosure may include one or more of lead (Pb), zirconium (Zr), titanium (Ti), zinc (Zn), nickel (Ni) and niobium (Nb), but the embodiments of this disclosure are not limited thereto.

[0487] According to another exemplary embodiment of this disclosure, the vibrating layer 511a or the first portion 511a1 may comprise a lead zirconate titanate (PZT)-based material, including lead (Pb), zirconium (Zr), and titanium (Ti); or may comprise a lead nickel zirconate (PZNN)-based material, including lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb), but the embodiments of this disclosure are not limited thereto. In another example, the vibrating layer 511a or the first portion 511a1 may comprise at least one or more of calcium titanate (CaTiO3), BaTiO3, and SrTiO3, none of which contain lead (Pb), but the embodiments of this disclosure are not limited thereto.

[0488] Each of the plurality of first portions 511a1 according to the exemplary embodiments of this disclosure may be disposed between a plurality of second portions 511a2 and may have a first width W1 parallel to a first direction X (or a second direction Y) and a length parallel to a second direction Y (or a first direction X). Each of the plurality of second portions 511a2 may have a second width W2 parallel to a first direction X (or a second direction Y) and may have a length parallel to a second direction Y (or a first direction X). The first width W1 may be the same as or different from the second width W2. For example, the first width W1 may be greater than the second width W2. For example, the first portions 511a1 and the second portions 511a2 may include linear or strip shapes having the same or different dimensions. Therefore, the vibrating layer 511a may include a 2-2 composite structure with piezoelectric properties having 2-2 vibration modes, and thus the vibrating layer 511a may have a resonant frequency of 20 kHz or lower, but embodiments of this disclosure are not limited thereto. For example, the resonant frequency of the vibrating layer 511a may vary based on at least one or more of the shape, length, and thickness.

[0489] In the example of the vibrating layer 511a, each of the plurality of first portions 511a1 and the plurality of second portions 511a2 can be arranged (or arranged) in parallel on the same plane (or the same layer). Each of the plurality of second portions 511a2 can be configured to fill the gap between two adjacent first portions of the plurality of first portions 511a1, and can be connected to or attached to the adjacent second portion 511a2. Thus, the vibrating layer 511a can extend to a desired size or length based on the lateral connection (or connection) between the first portions 511a1 and the second portions 511a2.

[0490] In the example of the vibrating layer 511a, the width (or dimension) W2 of each of the plurality of second portions 511a2 can gradually decrease along the direction from the central portion of the vibrating layer 511a or the vibration generator 510 to the two peripheries (or ends).

[0491] According to an exemplary embodiment of this disclosure, the second portion 511a2 with the largest width W2 among the plurality of second portions 511a2 may be located at the portion where the highest stress may concentrate when the vibrating layer 511a or the vibration generator 510 vibrates in the vertical direction Z (or the thickness direction). The second portion 511a2 with the smallest width W2 among the plurality of second portions 511a2 may be located at the portion where relatively low stress may occur when the vibrating layer 511a or the vibration generator 510 vibrates in the vertical direction Z. For example, the second portion 511a2 with the largest width W2 among the plurality of second portions 511a2 may be located at the central portion of the vibrating layer 511a, and the second portion 511a2 with the smallest width W2 among the plurality of second portions 511a2 may be located at each of the two peripheries of the vibrating layer 511a. Therefore, when the vibrating layer 511a or the vibration generator 510 vibrates in the vertical direction Z, interference of sound waves occurring in the portion with the highest stress concentration or overlap of resonant frequencies can be reduced or minimized. Therefore, the sound pressure level dip that occurs in the low-pitched vocal cords can be reduced, thereby improving the flatness of the sound characteristics in the low-pitched vocal cords. For example, the flatness of sound characteristics can be the level of deviation between the highest and lowest sound pressure levels.

[0492] In the vibrating layer 511a, each of the plurality of first portions 511a1 can have a different size (or width). For example, the size (or width) of each of the plurality of first portions 511a1 can gradually decrease or increase in the direction from the central portion of the vibrating layer 511a or the vibration generator 510 to the two peripheries (or ends). For example, in the vibrating layer 511a, based on the vibration of each of the plurality of first portions 511a with different sizes, the sound pressure level characteristics of the sound can be enhanced and the sound reproduction frequency band can be increased based on various inherent vibration frequencies.

[0493] Multiple second portions 511a2 can be disposed between multiple first portions 511a1. Therefore, in the vibration layer 511a or vibration generator 510, the vibrational energy of the links in a unit cell of each first portion 511a1 can be increased by the corresponding second portion 511a2, thereby increasing the vibrational characteristics and ensuring piezoelectric properties and flexibility. For example, the second portion 511a2 may comprise one or more of epoxy-based polymers, acrylic polymers, and silicone polymers, but embodiments of this disclosure are not limited thereto.

[0494] According to exemplary embodiments of this disclosure, multiple second portions 511a2 can be configured as organic material portions. For example, the organic material portions can be disposed between the inorganic material portions, thus absorbing impacts applied to the inorganic material portions (or the first portion), releasing stress concentrated on the inorganic material portions to improve the overall durability of the vibration layer 511a or vibration generator 510, and providing flexibility to the vibration layer 511a or vibration generator 510. Therefore, the vibration generator 510 can be flexible and thus can be bent into a shape matching the shape of the curved portion of the support member. For example, the vibration generator 510 can be flexible and thus can be arranged along a shape corresponding to the shape of the curved portion of the support member.

[0495] According to exemplary embodiments of this disclosure, the plurality of second portions 511a2 may have a modulus (or Young's modulus) and viscoelasticity lower than that of each first portion 511a1. Therefore, the second portions 511a2 may enhance the reliability of each first portion 511a1, which is susceptible to impact due to its brittle nature. For example, the second portions 511a2 may be configured as a material having a loss coefficient of about 0.01 to about 1 and a modulus of about 0.1 GPa to about 10 GPa.

[0496] The organic material portion disposed at the second portion 511a2 may include one or more of organic materials, organic polymers, organic piezoelectric materials, or organic non-piezoelectric materials that have flexible properties compared to the inorganic material portion of the first portion 511a1. For example, the second portion 511a2 may be referred to as an adhesive portion, elastic portion, bending portion, damping portion, or flexible portion, etc., but the embodiments of this disclosure are not limited thereto.

[0497] Multiple first portions 511a1 and second portions 511a2 can be disposed (or connected) on the same plane; therefore, the vibration layer 511a according to an exemplary embodiment of the present disclosure can have a single film or a single film type. For example, the vibration layer 511a can have a structure in which multiple first portions 511a1 are connected to one side. For example, multiple first portions 511a1 can have a connection structure over the entire vibration layer 511a. For example, the vibration layer 511a can vibrate vertically by the first portions 511a1 having vibration characteristics, and can be bent into a curved shape by the flexible second portions 511a2. Furthermore, in the vibration layer 511a according to an exemplary embodiment of the present disclosure, the dimensions of the first portions 511a1 and the second portions 511a2 can be adjusted based on the piezoelectric characteristics and flexibility required by the vibration layer 511a or the vibration generator 510. As an exemplary embodiment of the present disclosure, when the vibration layer 511a requires piezoelectric characteristics rather than flexibility, the dimensions of the first portions 511a1 can be adjusted to be larger than the dimensions of the second portions 511a2. As another example embodiment of this disclosure, when the vibrating layer 511a requires flexibility rather than piezoelectric properties, the size of the second portion 511a2 can be adjusted to be larger than the size of the first portion 511a1. Therefore, the size of the vibrating layer 511a can be adjusted based on the required properties of the vibrating layer 511a, thus the vibrating layer 511a can be easily designed.

[0498] The first electrode layer 511b may be disposed on the first surface (or upper surface) of the vibration layer 511a. The first electrode layer 511b may be commonly disposed on the first surface of each of the plurality of first portions 511a1 and the first surface of each of the plurality of second portions 511a2, or may be commonly connected to the first surface of each of the plurality of first portions 511a1 and the first surface of each of the plurality of second portions 511a2, and may be electrically connected to the first surface of each of the plurality of first portions 511a1. For example, the first electrode layer 511b may be in the shape of a single electrode (or a single electrode) disposed on the entire first surface of the vibration layer 511a. For example, the first electrode layer 511b may have a shape substantially the same as that of the vibration layer 511a, but the embodiments of this disclosure are not limited thereto.

[0499] The second electrode layer 511c can be disposed on a second surface (or rear surface) that is different from (or opposite to) the first surface of the vibration layer 511a. The second electrode layer 511c can be commonly disposed on the second surface of each of the plurality of first portions 511a1 and the second surface of each of the plurality of second portions 511a2, or commonly connected to the second surfaces of each of the plurality of first portions 511a1 and the second surfaces of each of the plurality of second portions 511a2, and can be electrically connected to the second surface of each of the plurality of first portions 511a1. For example, the second electrode layer 511c can be in the shape of a single electrode (or a single electrode) disposed on the entire second surface of the vibration layer 511a. The second electrode layer 511c can have the same shape as the vibration layer 511a, but the embodiments of this disclosure are not limited thereto.

[0500] According to exemplary embodiments of the present disclosure, one or more of the first electrode layer 511b and the second electrode layer 511c may be formed of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, the transparent or semi-transparent conductive material may include indium tin oxide (ITO) or indium zinc oxide (IZO), but embodiments of the present disclosure are not limited thereto. The opaque conductive material may include aluminum (Al), copper (Cu), gold (Au), silver (Ag), molybdenum (Mo), magnesium (Mg), etc., or alloys thereof, but embodiments of the present disclosure are not limited thereto.

[0501] The vibrating layer 511a can be polarized by applying a certain voltage to the first electrode layer 511b and the second electrode layer 511c in a certain temperature atmosphere or in a temperature atmosphere that can be changed from high temperature to room temperature, but the embodiments of this disclosure are not limited thereto. For example, the vibrating layer 511a can vibrate by alternately and repeatedly contracting and / or expanding based on the inverse piezoelectric effect according to the sound signal (or voice signal or drive signal) applied from the outside to the first electrode layer 511b and the second electrode layer 511c. For example, the vibrating layer 511a can vibrate based on vertical vibration d33 and planar vibration d31 according to the sound signal applied to the first electrode layer 511b and the second electrode layer 511c. The vibrating layer 511a can increase the displacement of the vibrating member by contracting and / or expanding in the planar direction, thereby further improving the vibration of the vibrating member.

[0502] The vibration generator 510 according to the first exemplary embodiment of the present disclosure may further include a first cover member 512 and a second cover member 513.

[0503] The first cover member 512 may be disposed on the first surface of the vibrating portion 511. For example, the first cover member 512 may be configured to cover the first electrode layer 511b. Therefore, the first cover member 512 can protect the first electrode layer 511b.

[0504] The second cover member 513 may be disposed on the second surface of the vibrating portion 511. For example, the second cover member 513 may be configured to cover the second electrode layer 511c. Therefore, the second cover member 513 can protect the second electrode layer 511c.

[0505] According to exemplary embodiments of the present disclosure, the first cover member 512 and the second cover member 513 may each comprise one or more materials selected from plastic, fiber, cloth, paper, leather, rubber, and wood, but embodiments of the present disclosure are not limited thereto. For example, each of the first cover member 512 and the second cover member 513 may comprise the same material or different materials. For example, each of the first cover member 512 and the second cover member 513 may be a polyimide (PI) film or a polyethylene terephthalate (PET) film, but embodiments of the present disclosure are not limited thereto.

[0506] According to an exemplary embodiment of this disclosure, the first cover member 512 can be connected or coupled to the first electrode layer 511b via the first adhesive layer 514. For example, the first cover member 512 can be connected or coupled to the first electrode layer 511b via a film lamination process using the first adhesive layer 514.

[0507] According to an exemplary embodiment of this disclosure, the second cover member 513 can be connected or coupled to the second electrode layer 511c via the second adhesive layer 515. For example, the second cover member 513 can be connected or coupled to the second electrode layer 511c via a film lamination process using the second adhesive layer 515. For example, the vibration generator 510 can be implemented as a single membrane via the first cover member 512 and the second cover member 513.

[0508] A first adhesive layer 514 may be disposed between the first electrode layer 511b and the first cover member 512. A second adhesive layer 515 may be disposed between the second electrode layer 511c and the second cover member 513. For example, the first adhesive layer 514 and the second adhesive layer 515 may be disposed between the first cover member 512 and the second cover member 513 to completely surround the vibration layer 511a, the first electrode layer 511b, and the second electrode layer 511c. For example, the vibration layer 511a, the first electrode layer 511b, and the second electrode layer 511c may be embedded or built into the first adhesive layer 514 and the second adhesive layer 515.

[0509] Each of the first adhesive layer 514 and the second adhesive layer 515 according to an exemplary embodiment of the present disclosure may include an electrically insulating material that is viscous and capable of compression and decompression. For example, each of the first adhesive layer 514 and the second adhesive layer 515 may include an epoxy resin, an acrylic resin, a silicone resin, or a polyurethane resin, but embodiments of the present disclosure are not limited thereto.

[0510] According to an exemplary embodiment of this disclosure, either the first cover member 512 or the second cover member 513 can be connected to or attached to the curved portion 350 of the support member 300 via a connecting member 520, such as Figure 5 and Figure 6 As shown in the image.

[0511] According to an exemplary embodiment of this disclosure, either the first cover member 512 or the second cover member 513 can be connected to or attached to the curved portion 350 of the support member 300 via the first connecting member 520, the plate 540, and the second connecting members 550 and 560, such as Figure 5 , Figures 7 to 9 , Figure 12 and Figure 15 As shown in the image.

[0512] The vibration generator 510 according to an exemplary embodiment of the present disclosure may further include a first power line PL1 disposed at a first cover member 512, a second power line PL2 disposed at a second cover member 513, and a pad portion 516 electrically connected to the first power line PL1 and the second power line PL2.

[0513] A first power line PL1 may be disposed between the first electrode layer 511b and the first cover member 512, and may be electrically connected to the first electrode layer 511b. The first power line PL1 may extend a considerable length in the second direction Y and may be electrically connected to the central portion of the first electrode layer 511b. As an embodiment of this disclosure, the first power line PL1 may be electrically connected to the first electrode layer 511b via an anisotropic conductive film. As another example embodiment of this disclosure, the first power line PL1 may be electrically connected to the first electrode layer 511b via a conductive material (or particles) included in the first adhesive layer 514.

[0514] A second power line PL2 may be disposed between the second electrode layer 511c and the second cover member 513, and may be electrically connected to the second electrode layer 511c. The second power line PL2 may extend a considerable length in the second direction Y and may be electrically connected to the central portion of the second electrode layer 511c. As an example embodiment of this disclosure, the second power line PL2 may be electrically connected to the second electrode layer 511c via an anisotropic conductive film. As another example embodiment of this disclosure, the second power line PL2 may be electrically connected to the second electrode layer 511c via a conductive material (or particles) included in the second adhesive layer 515.

[0515] For example, the first power line PL1 can be configured not to overlap with the second power line PL2. When the first power line PL1 is configured not to overlap with the second power line PL2, short circuits between the first power line PL1 and the second power line PL2 can be prevented.

[0516] The pad portion 516 may be disposed at a peripheral portion of either the first cover member 512 or the second cover member 513 to be electrically connected to a portion (or an end) of each of the first power line PL1 and the second power line PL2.

[0517] According to an exemplary embodiment of the present disclosure, the pad portion 516 may include a first pad electrode electrically connected to one end of a first power line PL1 and a second pad electrode electrically connected to one end of a second power line PL2.

[0518] The first pad electrode may be disposed at a peripheral portion of either the first cover member 512 or the second cover member 513 to be electrically connected to a portion of the first power line PL1. For example, the first pad electrode may pass through either the first cover member 512 or the second cover member 513 to be electrically connected to a portion of the first power line PL1.

[0519] The second pad electrode can be arranged parallel to the first pad electrode to be electrically connected to a portion of the second power line PL2. For example, the second pad electrode can pass through either the first cover member 512 or the second cover member 513 to be electrically connected to a portion of the second power line PL2.

[0520] According to an exemplary embodiment of this disclosure, each of the first power line PL1, the second power line PL2, and the pad portion 516 may be configured to be transparent, translucent, or opaque.

[0521] According to another exemplary embodiment of this disclosure, the pad portion 516 can be electrically connected to the signal cable 517.

[0522] The signal cable 517 can be electrically connected to the pad portion 516 disposed at the vibration generator 510, and can supply the vibration generator 510 with a vibration drive signal (or sound signal or voice signal) provided from the sound processing circuit. According to an exemplary embodiment of this disclosure, the signal cable 517 may include a first terminal electrically connected to a first pad electrode of the pad portion 516 and a second terminal electrically connected to a second pad electrode of the pad portion 516. For example, the signal cable 517 may be a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multilayer printed circuit, or a flexible multilayer printed circuit board, but embodiments of this disclosure are not limited thereto.

[0523] The sound processing circuit can generate an AC vibration drive signal, including a first vibration drive signal and a second vibration drive signal, based on sound data provided from an external sound data generation circuit. The first vibration drive signal can be one of a positive (+) vibration drive signal and a negative (-) vibration drive signal, and the second vibration drive signal can also be one of a positive (+) vibration drive signal and a negative (-) vibration drive signal. For example, the first vibration drive signal can be supplied to the first electrode layer 511b via the first terminal of the signal cable 517, the first pad electrode of the pad portion 516, and the first power line PL1. The second vibration drive signal can be supplied to the second electrode layer 511c via the second terminal of the signal cable 517, the second pad electrode of the pad portion 516, and the second power line PL2.

[0524] According to an example embodiment of this disclosure, the signal cable 517 may be configured to be transparent, semi-transparent, or opaque.

[0525] The vibration generator 510 according to the first exemplary embodiment of this disclosure can be implemented as a thin film or a thin film type, wherein a first portion 511a1 having piezoelectric properties and a second portion 511a2 having flexibility are alternately repeated and connected. Therefore, the vibration generator 510 can be bent into a shape corresponding to the shape of the curved portion of the support member or the shape of the vibrating member. For example, when the vibration generator 510 is connected or coupled to a vibrating member including various curved portions via a connecting member, the vibration generator 510 can be bent into a curved shape along the shape of the curved portion of the vibrating member, and even when bent into a curved shape, its reliability against damage or breakage is not reduced. Furthermore, in the vibration generator 510 according to the first exemplary embodiment of this disclosure, the vibration width (or displacement width) can be increased due to the flexibility of the flexible second portion 511a2. Therefore, the sound characteristics and / or sound pressure level characteristics generated by the vibration of the vibrating member can be enhanced.

For example, each of the plurality of first portions 511a1 can have a hexahedral shape (or a hexahedral object shape) having the same dimensions, and can be arranged in a grid pattern. Each of the plurality of first portions 511a1 can include elements that can be referenced above.

The second portion 511a2 may be configured to fill the gap or space between two adjacent first portions 511a1 or to surround each of the plurality of first portions 511a1, and thus may be connected to or attached to adjacent first portions 511a1. According to an exemplary embodiment of this disclosure, the width W4 of the second portion 511a2 disposed between two adjacent first portions 511a1 along the first direction X may be the same as or different from the width W3 of the first portion 511a1, and the width W4 of the second portion 511a2 disposed between two adjacent first portions 511a1 along the second direction Y may be the same as or different from the width W3 of the first portion 511a1.

The second portion 511a2 may be configured to surround each of the plurality of first portions 511a1, and thus may be connected to or attached to the side surface of each of the plurality of first portions 511a1. Each of the plurality of first portions 511a1 and the second portion 511a2 may be disposed (or arranged) in parallel on the same plane (or the same layer). The second portion 511a2 may include components that can be referenced above. Figures 24 to 26 The second part 511a2 describes essentially the same organic material; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0540] According to another exemplary embodiment of this disclosure, 2N adjacent first portions 511a1 (where N is a natural number greater than or equal to 2) of a plurality of first portions 511a1 having a triangular shape can be arranged adjacent to each other to form a 2N-angle shape. For example, six adjacent first portions 511a1 of the plurality of first portions 511a1 can be adjacent to each other to form a hexagonal shape (or a regular hexagonal shape). The vertices of the six adjacent first portions 511a1 forming the hexagonal shape can be adjacent to each other in the central portion (or center portion) of the hexagonal shape. A second portion 511a2 can be configured to surround each of the plurality of first portions 511a1, and thus can be connected to or attached to the side surface of each of the plurality of first portions 511a1. Each of the plurality of first portions 511a1 and second portions 511a2 can be arranged (or arranged) in parallel on the same plane (or the same layer).

[0541] Figure 30 A vibration generator according to another exemplary embodiment of the present disclosure is illustrated. Figure 31 It is along Figure 30 The cross-sectional view shown is taken from line IV-IV'. Figure 30 and Figure 31 Examples of references Figures 1 to 23C Another example implementation of the described vibration generator.

[0542] Reference Figure 30 and Figure 31According to another exemplary embodiment of the present disclosure, the vibration generator 510 may include a first vibration portion 511-1 and a second vibration portion 511-2.

[0543] Each of the first vibrating portion 511-1 and the second vibrating portion 511-2 can be electrically separated and disposed, while being spaced apart from each other along a first direction X. Each of the first vibrating portion 511-1 and the second vibrating portion 511-2 can alternately and repeatedly contract and / or expand to vibrate based on the piezoelectric effect. The first vibrating portion 511-1 and the second vibrating portion 511-2 can be arranged or laid flat at a certain interval (or distance) D1. Therefore, the vibration generator 510 with the first vibrating portion 511-1 and the second vibrating portion 511-2 arranged or laid flat can be referred to as a vibration array, a vibration array portion, a vibration module array portion, a vibration array structure, a laid-flat vibration array, a laid-flat vibration array module, or a laid-flat vibration membrane, but the embodiments of this disclosure are not limited thereto.

[0544] Each of the first vibration portion 511-1 and the second vibration portion 511-2 according to the exemplary embodiments of this disclosure may have a quadrilateral shape. For example, each of the first vibration portion 511-1 and the second vibration portion 511-2 may have a quadrilateral shape with a width of approximately 5 cm or greater. For example, each of the first vibration portion 511-1 and the second vibration portion 511-2 may have a square shape with dimensions of 5 cm × 5 cm or greater, but the embodiments of this disclosure are not limited thereto.

[0545] Each of the first vibration portion 511-1 and the second vibration portion 511-2 can be arranged or laid flat on the same plane, so that the vibration generator 510 can have an enlarged area based on the tiling of the first vibration portion 511-1 and the second vibration portion 511-2, which have relatively small dimensions.

[0546] Each of the first vibrating portion 511-1 and the second vibrating portion 511-2 can be arranged or laid out at a certain interval (or distance), thus enabling it to be driven as a complete unit rather than an independently driven vibrating device (or a single vibrating device). According to an exemplary embodiment of this disclosure, the first separation distance (or first distance or first interval) D1 between the first vibrating portion 511-1 and the second vibrating portion 511-2 relative to the first direction X can be 0.1 mm or greater and less than 3 cm, but embodiments of this disclosure are not limited thereto.

[0547] According to an exemplary embodiment of this disclosure, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 may be configured or tiled to have a separation distance (or interval) D1 of 0.1 mm or greater and less than 3 cm, thus enabling it to be driven as a vibrating device to increase the sound reproduction bandwidth and improve the sound pressure level characteristics of the sound generated based on the individual vibrations of the first vibrating portion 511-1 and the second vibrating portion 511-2. For example, the first vibrating portion 511-1 and the second vibrating portion 511-2 may be configured with an interval D1 of 0.1 mm or greater and less than 5 mm to increase the sound reproduction bandwidth of the sound generated based on the individual vibrations of the first vibrating portion 511-1 and the second vibrating portion 511-2 and to increase the sound of the low-pitched vocal bands (e.g., sound pressure level characteristics at 500 Hz or lower).

[0548] According to an exemplary embodiment of this disclosure, when the first vibration portion 511-1 and the second vibration portion 511-2 are provided with a spacing D1 of less than 0.1 mm or no spacing D1, the reliability of the first vibration portion 511-1 and the second vibration portion 511-2 or the vibration generator 510 may be reduced due to damage or cracks caused by the physical contact between them that occurs when each of the first vibration portion 511-1 and the second vibration portion 511-2 vibrates.

[0549] According to an exemplary embodiment of this disclosure, when the first vibrating portion 511-1 and the second vibrating portion 511-2 are arranged with a spacing D1 of 3 cm or greater, the first vibrating portion 511-1 and the second vibrating portion 511-2 may not be driven as a vibrating device due to the independent vibration of each of them. Therefore, the reproduction frequency band and sound pressure level characteristics of the sound generated based on the vibration of the first vibrating portion 511-1 and the second vibrating portion 511-2 can be reduced. For example, when the first vibrating portion 511-1 and the second vibrating portion 511-2 are arranged with a spacing D1 of 3 cm or greater, the sound characteristics and sound pressure level characteristics of the low-pitched sound band (e.g., at 500 Hz or lower) may both be reduced.

[0550] According to an exemplary embodiment of this disclosure, when the first vibration portion 511-1 and the second vibration portion 511-2 are arranged at a 5mm interval, each of the first vibration portion 511-1 and the second vibration portion 511-2 may not be able to be perfectly driven as a vibration device. Therefore, the sound characteristics and sound pressure level characteristics of the low-pitched vocal cords (e.g., at 200Hz or lower) may both be reduced.

[0551] According to another exemplary embodiment of this disclosure, when the first vibrating portion 511-1 and the second vibrating portion 511-2 are arranged at a 1 mm interval, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 can be driven as a vibration device. Therefore, the sound reproduction bandwidth can be increased, and the sound of the low-pitched vocal band (e.g., sound pressure level characteristics at 500 Hz or lower) can be increased. For example, when the first vibrating portion 511-1 and the second vibrating portion 511-2 are arranged at a 1 mm interval, the vibration generator 510 can be implemented as a large-area vibrator, which is amplified based on the optimization of the separation distance between the first vibrating portion 511-1 and the second vibrating portion 511-2. Therefore, the vibration generator 510 can be driven as a large-area vibrator based on the individual vibrations of the first vibrating portion 511-1 and the second vibrating portion 511-2, thereby increasing the sound characteristics and sound pressure level characteristics, respectively, in the sound reproduction bandwidth and the low-pitched vocal band generated by the large-area vibration of the vibration generator 510.

[0552] Therefore, in order to achieve individual vibration (or a single vibration device) of the first vibrating part 511-1 and the second vibrating part 511-2, the separation distance D1 between the first vibrating part 511-1 and the second vibrating part 511-2 can be adjusted to 0.1 mm or more and less than 3 cm. Furthermore, in order to achieve individual vibration (or a single vibration device) of the first vibrating part 511-1 and the second vibrating part 511-2, and in order to improve the sound pressure level characteristics of the low-pitched vocal cords, the separation distance D1 between the first vibrating part 511-1 and the second vibrating part 511-2 can be adjusted to 0.1 mm or more and less than 5 mm.

[0553] Each of the first vibration portion 511-1 and the second vibration portion 511-2 according to an exemplary embodiment of the present disclosure may include a vibration layer 511a, a first electrode layer 511b, and a second electrode layer 511c.

[0554] The vibrating layer 511a of each of the first vibrating portion 511-1 and the second vibrating portion 511-2 may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the vibrating layer 511a of each of the first vibrating portion 511-1 and the second vibrating portion 511-2 may be configured to be similar to the above-mentioned... Figures 26 to 29 Any of the described vibrating layers 511a are substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0555] According to an exemplary embodiment of this disclosure, each of the first vibration portion 511-1 and the second vibration portion 511-2 may include the above-described references. Figures 26 to 29The vibration portion 511 described may be any one of the vibration portions 511, or may include different vibration portions 511.

[0556] The first electrode layer 511b can be disposed on the first surface of the vibration layer 511a and electrically connected to the first surface of the vibration layer 511a. The first electrode layer 511b can be referenced above. Figure 26 The first electrode layer 511b described is substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions thereof may be omitted for the sake of brevity.

[0557] The second electrode layer 511c can be disposed on the second surface of the vibration layer 511a and electrically connected to the second surface of the vibration layer 511a. The second electrode layer 511c can be referenced above. Figure 26 The second electrode layer 511c described is substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions thereof may be omitted for the sake of brevity.

[0558] The vibration generator 510 according to another exemplary embodiment of the present disclosure may also include a first cover member 512 and a second cover member 513.

[0559] The first cover member 512 may be disposed on the first surface of the vibration generator 510. For example, the first cover member 512 may cover the first electrode layer 511b disposed on the first surface of each of the first vibration portion 511-1 and the second vibration portion 511-2. Therefore, the first cover member 512 may be connected to the first surface of each of the first vibration portion 511-1 and the second vibration portion 511-2, or may support the first surface of each of the first vibration portion 511-1 and the second vibration portion 511-2. Thus, the first cover member 512 may protect the first surface or the first electrode layer 511b of each of the first vibration portion 511-1 and the second vibration portion 511-2.

[0560] The second cover member 513 may be disposed on the second surface of the vibration generator 510. For example, the second cover member 513 may cover the second electrode layer 511c disposed on the second surface of each of the first vibration portion 511-1 and the second vibration portion 511-2. Therefore, the second cover member 513 may be connected to the second surface of each of the first vibration portion 511-1 and the second vibration portion 511-2, or may support the second surface of each of the first vibration portion 511-1 and the second vibration portion 511-2. Thus, the second cover member 513 may protect the second surface or the second electrode layer 511c of each of the first vibration portion 511-1 and the second vibration portion 511-2.

[0561] According to exemplary embodiments of the present disclosure, the first cover member 512 and the second cover member 513 may each comprise one or more materials selected from plastic, fiber, leather, rubber, wood, cloth, and paper, but embodiments of the present disclosure are not limited thereto. For example, each of the first cover member 512 and the second cover member 513 may comprise the same material or different materials. For example, each of the first cover member 512 and the second cover member 513 may be a polyimide (PI) film or a polyethylene terephthalate (PET) film, but embodiments of the present disclosure are not limited thereto.

[0562] According to an exemplary embodiment of this disclosure, the first cover member 512 can be disposed on the first surface of each of the first vibrating portions 511-1 and the second vibrating portions 511-2 via a first adhesive layer 514. For example, the first cover member 512 can be directly disposed on the first surface of each of the first vibrating portions 511-1 and the second vibrating portions 511-2 via a film lamination process using the first adhesive layer 514. Therefore, each of the first vibrating portions 511-1 and the second vibrating portions 511-2 can be integrated (or arranged) or laid flat with the first cover member 512 with a certain interval D1.

[0563] According to an exemplary embodiment of this disclosure, the second cover member 513 can be disposed on the second surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2 via a second adhesive layer 515. For example, the second cover member 513 can be directly disposed on the second surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2 via a film lamination process using the second adhesive layer 515. Therefore, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 can be integrated (or stepped) with or laid flat with the second cover member 513 to have a certain interval D1. For example, the vibration generator 510 can be implemented as a single membrane via the first cover member 512 and the second cover member 513.

[0564] The first adhesive layer 514 may be disposed between the first vibrating portion 511-1 and the second vibrating portion 511-2, and disposed on the first surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2. For example, the first adhesive layer 514 may be formed on the rear surface (or inner surface) of the first cover member 512 facing each of the first surfaces of the first vibrating portion 511-1 and the second vibrating portion 511-2, filling between the first vibrating portion 511-1 and the second vibrating portion 511-2, and disposed between the first cover member 512 and the first surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2.

[0565] The second adhesive layer 515 may be disposed between the first vibrating portion 511-1 and the second vibrating portion 511-2, and at the second surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2. For example, the second adhesive layer 515 may be formed on the front surface (or inner surface) of the second cover member 513 facing the second surfaces of each of the first vibrating portion 511-1 and the second vibrating portion 511-2, filling between the first vibrating portion 511-1 and the second vibrating portion 511-2, and disposed between the first cover member 512 and the second surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2.

[0566] The first adhesive layer 514 and the second adhesive layer 515 may be connected or joined to each other between the first vibrating portion 511-1 and the second vibrating portion 511-2. Therefore, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 may be surrounded by the first adhesive layer 514 and the second adhesive layer 515. For example, the first adhesive layer 514 and the second adhesive layer 515 may be disposed between the first cover member 512 and the second cover member 513 to completely surround the first vibrating portion 511-1 and the second vibrating portion 511-2. For example, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 may be embedded or built into the first adhesive layer 514 and the second adhesive layer 515.

[0567] Each of the first adhesive layer 514 and the second adhesive layer 515 according to an exemplary embodiment of the present disclosure may include an electrically insulating material that is adhesive and capable of being compressed and decompressed. For example, each of the first adhesive layer 514 and the second adhesive layer 515 may include an epoxy resin, an acrylic resin, a silicone resin, or a polyurethane resin, but embodiments of the present disclosure are not limited thereto. Each of the first adhesive layer 514 and the second adhesive layer 515 may be configured to be transparent, translucent, or opaque.

[0568] According to another exemplary embodiment of the present disclosure, the vibration generator 510 may further include a first power line PL1 disposed at a first cover member 512, a second power line PL2 disposed at a second cover member 513, and a pad portion 518 electrically connected to the first power line PL1 and the second power line PL2.

[0569] A first power line PL1 may be disposed on the rear surface of the first surface of the first cover member 512 facing each of the first vibrating portions 511-1 and 511-2. The first power line PL1 may be connected or electrically connected and directly connected to the first electrode layer 511b of each of the first vibrating portions 511-1 and 511-2. For example, the first power line PL1 may be electrically connected to the first electrode layer 511b of each of the first vibrating portions 511-1 and 511-2 via an anisotropic conductive film or conductive material (or particles) included in the first adhesive layer 514.

[0570] According to an exemplary embodiment of this disclosure, the first power line PL1 may include a first upper power line PL11 and a second upper power line PL12 disposed along a second direction Y. For example, the first upper power line PL11 may be connected or electrically connected and directly connected to the first electrode layer 511b of the first vibration portion 511-1. The second upper power line PL12 may be connected or electrically connected and directly connected to the first electrode layer 511b of the second vibration portion 511-2.

[0571] The second power line PL2 can be disposed on the front surface of the second cover member 513 facing each of the second surfaces of the first vibration portion 511-1 and the second vibration portion 511-2. The second power line PL2 can be connected or electrically connected and directly connected to the second electrode layer 511c of each of the first vibration portion 511-1 and the second vibration portion 511-2. For example, the second power line PL2 can be electrically connected to the second electrode layer 511c of each of the first vibration portion 511-1 and the second vibration portion 511-2 through an anisotropic conductive film or conductive material (or particles) included in the second adhesive layer 515.

[0572] According to an exemplary embodiment of this disclosure, the second power line PL2 may include a first lower power line PL21 and a second lower power line PL22 disposed along a second direction Y. The first lower power line PL21 may be electrically connected to the second electrode layer 511c of the first vibration portion 511-1. For example, the first lower power line PL21 may be configured not to overlap with the first upper power line PL11. When the first lower power line PL21 is configured not to overlap with the first upper power line PL11, a short circuit between the first power line PL1 and the second power line PL2 can be prevented. The second lower power line PL22 may be electrically connected to the second electrode layer 511c of the second vibration portion 511-2. For example, the second lower power line PL22 may be configured not to overlap with the second upper power line PL12. When the second lower power line PL22 is configured not to overlap with the second upper power line PL12, a short circuit between the first power line PL1 and the second power line PL2 can be prevented.

[0573] The pad portion 518 may be disposed at a peripheral portion of either the first cover member 512 or the second cover member 513 to be electrically connected to a portion (or an end) of each of the first power line PL1 and the second power line PL2.

[0574] According to an exemplary embodiment of the present disclosure, the pad portion 518 may include a first pad electrode electrically connected to one end of a first power line PL1 and a second pad electrode electrically connected to one end of a second power line PL2.

[0575] The first pad electrode can be commonly connected to a portion of each of the first upper power line PL11 and the second upper power line PL12 of the first power line PL1. For example, a portion of each of the first upper power line PL11 and the second upper power line PL12 can branch off from the first pad electrode. The second pad electrode can be commonly connected to a portion of each of the first lower power line PL21 and the second lower power line PL22 of the second power line PL2. For example, a portion of each of the first lower power line PL21 and the second lower power line PL22 can branch off from the second pad electrode.

[0576] The vibration generator 510 according to another exemplary embodiment of this disclosure may also include a signal cable 519.

[0577] The signal cable 519 can be electrically connected to the pad portion 518 disposed at the vibration generator 510, and can supply the vibration generator 510 with a vibration drive signal (or sound signal or voice signal) provided from the sound processing circuit. According to an exemplary embodiment of this disclosure, the signal cable 519 may include a first terminal electrically connected to a first pad electrode of the pad portion 518 and a second terminal electrically connected to a second pad electrode of the pad portion 518. For example, the signal cable 519 may be a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multilayer printed circuit, or a flexible multilayer printed circuit board, but embodiments of this disclosure are not limited thereto.

[0578] The sound processing circuit can generate an AC vibration drive signal, including a first vibration drive signal and a second vibration drive signal, based on sound data. The first vibration drive signal can be one of a positive (+) vibration drive signal and a negative (-) vibration drive signal, and the second vibration drive signal can also be one of a positive (+) vibration drive signal and a negative (-) vibration drive signal. For example, the first vibration drive signal can be supplied to the first electrode layer 511b of each of the first vibration section 511-1 and the second vibration section 511-2 via the first terminal of the signal cable 519, the first pad electrode of the pad portion 518, and the first power line PL1. The second vibration drive signal can be supplied to the second electrode layer 511c of each of the first vibration section 511-1 and the second vibration section 511-2 via the second terminal of the signal cable 519, the second pad electrode of the pad portion 518, and the second power line PL2.

[0579] The vibration generator 510 according to another exemplary embodiment of the present disclosure can be implemented as a thin film or a thin film type, and therefore can be bent into a shape corresponding to the shape of the vibrating member or vibrating object, and can easily vibrate the vibrating member including various curved portions, thereby enhancing the sound characteristics and / or sound pressure level characteristics in the low-pitched vocal cords generated based on the vibration of the vibrating member. Furthermore, the vibration generator 510 according to another exemplary embodiment of the present disclosure may include a first vibrating portion 511-1 and a second vibrating portion 511-2 arranged (or tiled) at a certain interval D1, so as to be implemented as a single vibrator without being driven independently, and therefore can be driven as a large-area vibrator based on the individual vibration of the first vibrating portion 511-1 and the second vibrating portion 511-2.

[0580] Figure 32 A vibration generator according to another exemplary embodiment of the present disclosure is illustrated. Figure 32 Examples are shown in Figure 30 and Figure 31 The example embodiment shown is a vibration generator with four vibration sections. Therefore, in the following, other elements besides the four vibration sections and related components are indicated by similar reference numerals, and their descriptions may be omitted or will be briefly repeated. Figure 31 Examples along Figure 32 The section cut by line IV-IV' shown in the diagram.

[0581] Reference Figure 31 and Figure 32 According to another exemplary embodiment of the present disclosure, the vibration generator 510 may include a plurality of vibration portions 511-1 to 511-4.

[0582] Multiple vibrating portions 511-1 to 511-4 can be electrically disconnected and arranged spaced apart from each other along a first direction X and a second direction Y. For example, the multiple vibrating portions 511-1 to 511-4 can be arranged in an i×j configuration or laid flat on the same plane. Therefore, based on the tiling of multiple vibrating portions 511-1 to 511-4 with relatively small dimensions, the vibration generator 510 can be implemented with a large area. For example, i can be the number of vibration generators arranged along the first direction X, or it can be a natural number of 2 or greater, and j can be the number of vibration generators arranged along the second direction Y, and it can be a natural number of 2 or greater that is the same as or different from i. For example, the multiple vibrating portions 511-1 to 511-4 can be arranged or laid flat in a 2×2 configuration, but embodiments of this disclosure are not limited thereto. In the following description, an example of a vibration generator 510 including multiple vibrating portions 511-1 to 511-4 will be described.

[0583] According to an exemplary embodiment of this disclosure, the first vibrating portion 511-1 and the second vibrating portion 511-2 may be spaced apart from each other along a first direction X. The third vibrating portion 511-3 and the fourth vibrating portion 511-4 may be spaced apart from each other along the first direction X, and may be spaced apart from each of the first vibrating portion 511-1 and the second vibrating portion 511-2 along a second direction Y. The first vibrating portion 511-1 and the third vibrating portion 511-3 may be spaced apart from each other along the second direction Y so as to face each other. The second vibrating portion 511-2 and the fourth vibrating portion 511-4 may be spaced apart from each other along the second direction Y so as to face each other.

[0584] The first vibrating portion 511-1 to the fourth vibrating portion 511-4 can be disposed between the first cover member 512 and the second cover member 513. For example, each of the first cover member 512 and the second cover member 513 can be connected to the first vibrating portion 511-1 to the fourth vibrating portion 511-4, or can jointly support the first vibrating portion 511-1 to the fourth vibrating portion 511-4. Therefore, the first vibrating portion 511-1 to the fourth vibrating portion 511-4 can be driven as a vibrating device (or a single vibrating device). For example, the first vibrating portion 511-1 to the fourth vibrating portion 511-4 can be laid flat at certain intervals by the cover members 512 and 513, and therefore can be driven as a vibrating device (or a single vibrating device).

[0585] According to the exemplary embodiments of this disclosure, as referred to above... Figure 30 and Figure 31In order to achieve complete single-unit vibration or large-area vibration, the first vibration part 511-1 to the fourth vibration part 511-4 can be set (or laid flat) at intervals of 0.1 mm or more and less than 3 cm in each of the first direction X and the second direction Y, or they can be set (or laid flat) at intervals of 0.1 mm or more and less than 5 mm.

[0586] Each of the first vibration portion 511-1 to the fourth vibration portion 511-4 according to an exemplary embodiment of the present disclosure may include a vibration layer 511a, a first electrode layer 511b, and a second electrode layer 511c.

[0587] The vibrating layer 511a of each of the first vibrating portions 511-1 to the fourth vibrating portions 511-4 may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the vibrating layer 511a of each of the first vibrating portions 511-1 to the fourth vibrating portions 511-4 may be configured to be similar to the above-mentioned Figures 26 to 29 Any of the described vibrating layers 511a are substantially the same; therefore, similar reference numerals denote similar elements, and repeated descriptions may be omitted for brevity.

[0588] According to an exemplary embodiment of this disclosure, each of the first vibration portion 511-1 to the fourth vibration portion 511-4 may include the above-described references. Figures 26 to 29 The described vibration layer 511a may be any one of the vibration layers 511a, or may include different vibration layers 511a. According to another exemplary embodiment of this disclosure, one or more of the first vibration portion 511-1 to the fourth vibration portion 511-4 may include the vibration portions described above. Figures 26 to 29 The different vibration layers 511a are described.

[0589] The first electrode layer 511b can be disposed at the first surface of the corresponding vibration layer 511a and electrically connected to the first surface of the vibration layer 511a. The first electrode layer 511b can be referenced above.

Therefore, each of the first vibrating portions 511-1 to the fourth vibrating portions 511-4 may be surrounded by the first adhesive layer 514 and the second adhesive layer 515. For example, the first adhesive layer 514 and the second adhesive layer 515 may be disposed between the first cover member 512 and the second cover member 513 to completely surround the first vibrating portions 511-1 to the fourth vibrating portions 511-4. For example, each of the first vibrating portions 511-1 to the fourth vibrating portions 511-4 may be embedded or built into the first adhesive layer 514 and the second adhesive layer 515.

[0592] According to another exemplary embodiment of the present disclosure, the vibration generator 510 may further include a first power line PL1, a second power line PL2, and a pad portion 518.

[0593] Apart from the electrical connection structure between the first power line PL1 and the second power line PL2 and the first vibration part 511-1 to the fourth vibration part 511-4, the first power line PL1 and the second power line PL2 can be as described above. Figure 30 and Figure 31 Each of the first power line PL1 and the second power line PL2 described is substantially the same; therefore, in the following description, only the electrical connection structure between the first power line PL1 and the second power line PL2 and the first vibration part 511-1 to the fourth vibration part 511-4 will be briefly described.

[0594] According to an exemplary embodiment of the present disclosure, the first power line PL1 may include a first upper power line PL11 and a second upper power line PL12 disposed along the second direction Y. For example, the first upper power line PL11 may be electrically connected to a first electrode layer 511b of each of the first vibration portion 511-1 and the third vibration portion 511-3 disposed in a first row parallel to the second direction Y in the first vibration portion 511-1 to the fourth vibration portion 511-4.

[0595] According to an exemplary embodiment of the present disclosure, the second power line PL2 may include a first lower power line PL21 and a second lower power line PL22 disposed along the second direction Y. For example, the first lower power line PL21 may be electrically connected to a second electrode layer 511c disposed in each of the first vibration portion 511-1 and the third vibration portion 511-3 in a first row parallel to the second direction Y in the first vibration portion 511-1 to the fourth vibration portion 511-4. The second lower power line PL22 may be electrically connected to a second electrode layer 511c disposed in each of the second vibration portion 511-2 and the fourth vibration portion 511-4 in a second row parallel to the second direction Y in the first vibration portion 511-1 to the fourth vibration portion 511-4.

[0596] The pad portion 518 may be disposed at an edge portion of one of the first cover member 512 and the second cover member 513 for electrical connection to one side (or one end) of each of the first power line PL1 and the second power line PL2. The pad portion 518 may be connected to... Figure 30 and Figure 31 The pad portions 518 shown are substantially the same; therefore, similar reference numerals denote similar components, and repeated descriptions may be omitted for brevity.

[0597] According to another exemplary embodiment of this disclosure, the vibration generator 510 may have the same characteristics as described above. Figure 30 and Figure 31 The vibration generator 510 described has the same effect, therefore, for the sake of brevity, its repeated description can be omitted.

[0598] Figure 33 A vibration generator according to another exemplary embodiment of the present disclosure is illustrated, and Figure 34 It is along Figure 33 The example cross-section diagram shown is taken from line V-V'. Figure 33 and Figure 34 Examples of references Figures 1 to 23C Another example implementation of the described vibration generator.

[0599] Reference Figure 33 and Figure 34 According to another exemplary embodiment of the present disclosure, the vibration generator 510 may include a plurality of vibration generating portions 510A and 510B and an intermediate member (or intermediate component) 510m. For example, according to another exemplary embodiment of the present disclosure, the vibration generator 510 may include a first vibration generating portion 510A, a second vibration generating portion 510B, and an intermediate member 510m between the first vibration generating portion 510A and the second vibration generating portion 510B.

[0600] Multiple vibration generating portions (or a first vibration generating portion and a second vibration generating portion) 510A and 510B may overlap or stack to be displaced (or driven or vibrated) in the same direction in order to maximize the amplitude displacement of the vibrating member and / or the amplitude displacement of the vibration generator 510. One side (or end, or outer surface, or each corner) of each of the multiple vibration generating portions (or a first vibration generating portion and a second vibration generating portion) 510A and 510B may be aligned on a virtual extension line VL extending along a third direction Z, or may be located at the virtual extension line VL. For example, the first vibration generating portion 510A may be located on the front or rear surface of the second vibration generating portion 510B.

[0601] Multiple vibration generating parts (or the first vibration generating part and the second vibration generating part) 510A and 510B can be as described above. Figures 24 to 32 Any of the vibration generators 510 described herein may be omitted for the sake of brevity.

[0602] Multiple vibration generating portions 510A and 510B can overlap or stack to displace (or drive or vibrate) in the same direction based on the polarization direction of the vibration layer 511a. For example, when the vibration layer 511a of each of the first vibration generating portion 510A and the second vibration generating portion 510B has the same polarization direction, the second vibration generating portion 510B can be disposed on the front or rear surface of the first vibration generating portion 510A. For example, when the vibration layer 511a of each of the first vibration generating portion 510A and the second vibration generating portion 510B has opposite polarization directions, the second vibration generating portion 510B can be disposed on the front or rear surface of the first vibration generating portion 510A as a vertical reversal type.

[0603] An intermediate member 510m can be disposed or inserted between multiple vibration generating portions 510A and 510B. For example, the intermediate member 510m can be disposed between a second cover member 513 of the first vibration generating portion 510A and a first cover member 512 of the second vibration generating portion 510B. For example, the intermediate member 510m can be configured as an adhesive material including an adhesive layer, which has good adhesion or bonding force with respect to each of the multiple vertically overlapping vibration generators 210 and 230.

[0604] The intermediate component 510m according to an exemplary embodiment of this disclosure may include a foam pad, single-sided tape, double-sided tape, single-sided foam pad, double-sided foam pad, single-sided foam tape, double-sided foam tape, or adhesive, etc., but the embodiments of this disclosure are not limited thereto. For example, the adhesive layer of the intermediate component 510m may include epoxy-based, acrylic-based, silicone-based, or polyurethane-based materials, but the exemplary embodiments of this disclosure are not limited thereto. The adhesive layer of the intermediate component 510m may include a polyurethane-based material that has relatively ductile properties compared to acrylic acid in polyurethane and acrylic acid. Therefore, in the vibration generator 510 according to another embodiment of this disclosure, the vibration loss of the vibration generator 510 caused by displacement interference between the plurality of vibration generating parts 510A and 510B can be minimized, or each of the plurality of vibration generating parts 510A and 510B can be freely displaced.

[0605] According to another exemplary embodiment of this disclosure, the intermediate component 510m may include one or more of thermosetting adhesives, photocurable adhesives, and thermally bonded adhesives. For example, the intermediate component 510m may include a thermally bonded adhesive. The thermally bonded adhesive may be thermally activated or thermosetting. For example, the intermediate component 510m including a thermally bonded adhesive may attach or connect two adjacent vibration generating portions 510A and 510B by heat and pressure. For example, the intermediate component 510m including a thermally bonded adhesive may reduce or minimize the vibration loss of the vibration generator 510.

[0606] Multiple vibration generating parts 510A and 510B can be integrated into a single structure (or element or component) using a lamination process with intermediate component 510m. For example, multiple vibration generating parts 510A and 510B can be integrated into a single structure using a lamination process with rollers.

[0607] Figures 35A to 35D This is an example Figure 33 and Figure 34 An example perspective view of the stacked structure between the vibration layers of multiple vibration-generating parts shown.

[0608] Reference Figure 33 and Figure 35A The vibration layer 511a of each of the multiple vibration generating portions 510A and 510B may include multiple first portions 511a1 and multiple second portions 511a2 disposed between the multiple first portions 511a1. The vibration layer 511a may be related to the above-mentioned reference. Figure 26 The vibration layer 511a described is basically the same, so its repeated description can be omitted for the sake of brevity.

[0609] The first portion 511a1 of the lower vibration generating portion 510B and the first portion 511a1 of the upper vibration generating portion 510A can substantially overlap or stack without intersecting, or they can be aligned on a virtual extension line VL extending along a third direction Z, or they can be disposed on the virtual extension line VL. Similarly, the second portion 511a2 of the lower vibration generating portion 510B and the second portion 511a2 of the upper vibration generating portion 510A can substantially overlap or stack without intersecting, or they can be aligned on a virtual extension line VL extending along a third direction Z, or they can be disposed on the virtual extension line VL. Therefore, the first portion 511a1 of the multiple vibration generating parts 510A and 510B can substantially overlap or stack without interleaving, and can be displaced (or driven or vibrated) in the same direction. Thus, the amplitude displacement of the vibration generator 510 and / or the amplitude displacement of the vibration member can be increased or maximized by the combined vibration of the multiple vibration generating parts 510A and 510B, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated based on the vibration of the vibration member.

[0610] Reference Figure 33 and Figures 35B to 35D The vibration layer 511a of each of the plurality of vibration generating portions 510A and 510B may include a plurality of first portions 511a1 and second portions 511a2 disposed around each of the plurality of first portions 511a1. The vibration layer 511a may be as described above. Figures 27 to 29 The vibration layer 511a described is basically the same, so its repeated description can be omitted for the sake of brevity.

[0611] The first portion 511a1 of the lower vibration generating portion 510B and the first portion 511a1 of the upper vibration generating portion 510A can substantially overlap or stack without intersecting, or they can be aligned on a virtual extension line VL extending along a third direction Z, or they can be disposed on the virtual extension line VL. Similarly, the second portion 511a2 of the lower vibration generating portion 510B and the second portion 511a2 of the upper vibration generating portion 510A can substantially overlap or stack without intersecting, or they can be aligned on a virtual extension line VL extending along a third direction Z, or they can be disposed on the virtual extension line VL. Therefore, the first portion 511a1 of the multiple vibration generating parts 510A and 510B can substantially overlap or stack without interleaving each other, and can be displaced (or driven or vibrated) in the same direction. Thus, the amplitude displacement of the vibration generator 510 and / or the amplitude displacement of the vibration member can be increased or maximized by the combined vibration of the multiple vibration generating parts 510A and 510B, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated based on the vibration of the vibration member.

For example, the sign content can be directly attached to one or more of a first surface (or front surface) 600a and a second surface (or rear surface) 600b different from (or opposite to) the first surface 600a of the vibrating member 600. For example, the sign content can be printed on a medium such as paper, and the medium on which the sign content is printed can be directly attached to one or more of the first surface 600a and the second surface 600b of the vibrating member 600. For example, when the sign content is attached to the second surface 600b of the vibrating member 600, the vibrating member 600 can be configured as a transparent material.

[0618] The vibration member 600 according to an exemplary embodiment of the present disclosure may include a plate structure having a quadrilateral shape. For example, the vibration member 600 may include a plate structure having a quadrilateral shape. The vibration member 600 may include a width direction length parallel to a first direction X and a length direction length parallel to a second direction Y. For example, the vibration member 600 may include a rectangular shape, wherein the width direction length is relatively longer than the length direction length, but the embodiments of the present disclosure are not limited thereto. For example, the vibration member 600 may include a square shape with the width direction length and the length direction length being the same.

[0619] A support member 700 may be disposed on the rear surface of the vibrating member 600. The support member 700 may be configured to cover the rear surface of the vibrating member 600. The support member 700 may include a rear portion 710, a side portion 730, and a curved portion 750.

The rear portion 710, the side portion 730, and the curved portion 750 may be respectively referenced above. Figure 2 and Figure 3 The rear portion 310, side portion 330, and curved portion 350 are described as being substantially the same or substantially similar; therefore, Figures 2 to 11B The description (or details) of the support member 300 shown may be included in the description of Figures 36 to 38 The description of the support member 300 shown is included here. Therefore, its repeated description may be omitted or will be briefly given below.

[0620] The side 730 of the support member 700 can be connected to or attached to the rear peripheral portion of the vibration member 600 via the connecting member 601.

[0621] The connecting member 601 may be configured to minimize or prevent the transmission of vibrations from the vibrating member 600 to the support member 700. The connecting member 601 may include material properties suitable for blocking vibrations. For example, the connecting member 601 may include a material having elasticity for vibration absorption (or shock absorption). The connecting member 601 according to exemplary embodiments of this disclosure may be configured as a polyurethane material or a polyolefin material, but embodiments of this disclosure are not limited thereto. For example, the connecting member 601 may include one or more of adhesives, double-sided tape, double-sided foam tape, and double-sided cushioning tape, but embodiments of this disclosure are not limited thereto.

[0622] The connecting member 601 can prevent physical contact (or friction) between the vibrating member 600 and the side 730 of the support member 700, and therefore can prevent the occurrence of noise (or noise sound) caused by physical contact (or friction) between the vibrating member 600 and the support member 700. For example, the connecting member 601 can be a buffer member, an elastic member, a damping member, a vibration absorbing member, or a vibration blocking member, but the embodiments of this disclosure are not limited thereto.

[0623] The curved portion 750 of the support member 700 may include a plurality of curved portions 750. The curved portions 750 may be implemented at the rear portion 710 with predetermined intervals along one or more of the first direction X and the second direction Y.

[0624] Each of the plurality of curved portions 750 can vibrate together with the vibration of the vibration device 500 to cause the vibrating member 600 to vibrate. For example, each of the plurality of curved portions 750 can vibrate based on the vibration of the vibration device 500 to indirectly cause the vibrating member 600 to vibrate. Each of the plurality of curved portions 750 can be referenced above. Figure 2 and Figure 11B The described curved portions 350 are the same or substantially similar, therefore... Figures 2 to 11B The description (or details) of the curved portion 350 shown may be included in the description of the curved portion 350. Figures 36 to 38 The description of the curved portion 350 shown or adapted for use with Figures 36 to 38 The description of the curved portion 350 shown is therefore omitted or will be briefly given below.

[0625] According to an exemplary embodiment of this disclosure, each of the plurality of curved portions 750 may be implemented at the rear portion 710 to have a predetermined curvature. For example, each of the plurality of curved portions 750 may include a curved structure projecting in a direction from the rear portion 710 to the rear surface of the support member 700. For example, each of the plurality of curved portions 750 may project from the rear portion 710 to have a curved shape having a curvature (or a single curvature). For example, each of the plurality of curved portions 750 may have a curved structure having a curvature (or a single curvature) without an inflection point. For example, each of the plurality of curved portions 750 may project convexly in a direction from the rear portion 710 to the rear surface of the support member 700. For example, each of the plurality of curved portions 750 may have a single convex curved shape having a certain curvature.

[0626] According to another exemplary embodiment of this disclosure, one or more of the plurality of curved portions 750 may have different dimensions. For example, any one of the plurality of curved portions 750 may have a smaller dimension than the other curved portion 750, as referenced above. Figure 11B As described in the third curved section 350c.

[0627] The device 5 according to the fifth embodiment of this disclosure may further include a gap space GS disposed between the curved portion 750 of the support member 700 and the vibration member 600.

[0628] The gap space GS can be disposed between the curved portion 750 of the support member 700 and the rear surface of the vibrating member 600. The gap space GS can include a space for generating sound or sound pressure level based on the vibration of the curved portion 750, a space for smoothly performing the vibration of the curved portion 750, or a space for sound waves generated by the vibration of the vibrating device 500 to propagate to the vibrating member 600. For example, the gap space GS can be an air gap, a sound pressure level generating space, a sound space, a sound pressure level space, a sound-generating portion, a resonating box, a sound wave propagation path, a sound energy incident portion, or a sound path, but the embodiments of this disclosure are not limited thereto.

[0629] Vibration device 500 can be coupled to or attached to each of the plurality of bends 750 realized at support member 700. Vibration device 500 can cause each of the plurality of bends 750 to vibrate to output sound (or sound waves) to gap space GS, so that vibration member 600 can generate or output sound based on sound (or sound waves) transmitted through gap space GS.

[0630] The vibration device 500 according to an exemplary embodiment of the present disclosure can be individually coupled to or attached to each of the plurality of curved portions 750.

[0631] The vibration device 500 may have a size smaller than that of the curved portion 750. The vibration device 500 may be coupled to or attached to the curved portion 750 to have an isoangular shape based on the curvature of the curved portion 750, but embodiments of this disclosure are not limited thereto. For example, the vibration device 500 may be coupled to or attached to the curved portion 750 to have a non-isoangular shape not based on the curvature of the curved portion 750 or having a curvature different from that of the curved portion 750.

[0632] According to another exemplary embodiment of this disclosure, the vibration device 500 can be coupled to or attached to the bending portion 750, and thus can have or receive prestress based on the bending portion 750. For example, the vibration device 500 can be coupled to or attached to the bending portion 750, and thus can be maintained in a state where the vibration device 500 has or receives prestress based on the bending portion 750. For example, the vibration device 500 can receive tensile stress or include tensile stress based on the curvature of the bending portion 750. For example, the bending portion 750 can be implemented to apply tensile stress only to the vibration device 500 in order to enhance the vibration characteristics of the vibration device 500. Therefore, the vibration device 500 can vibrate in a state where the vibration device 500 receives prestress (or pre-tension) or is bent into a bending shape, thus the second moment of inertia can be increased, or the vibration direction can be implemented in a single direction.

[0633] Vibration equipment 500 may include the above reference Figures 6 to 9The described vibration equipment and the above references Figures 24 to 35D The vibration generator described. Therefore, the above refers to... Figures 6 to 9 The description of the vibration equipment and the above references Figures 24 to 35D The description of the vibration generator may include in the description of the vibration generator. Figure 37 The description of each of the plurality of vibration devices 500 shown or adapted for use in the vibration of... Figure 37 The description of each of the plurality of vibration devices 500 shown is omitted for brevity.

[0634] The vibrating device 500 disposed at each of the plurality of curved portions 750 can be configured to produce sound from vocal cords of the same pitch, or can be configured to produce sound from vocal cords of different pitches. For example, the device 5 according to the fifth exemplary embodiment of the present disclosure may include a plurality of vibrating devices 500 disposed at the plurality of curved portions 750, and the plurality of vibrating devices 500 may be configured to produce sound from vocal cords of the same pitch, or may be configured to produce sound from vocal cords of different pitches.

[0635] One or more of the plurality of vibration devices 500 can be configured to produce sound from different pitch vocal cords or sound from lower pitch vocal cords. Therefore, the device 5 according to the fifth exemplary embodiment of the present disclosure can output sound (e.g., stereo or stereophonic sound) based on sound generated or output according to the region-based vibration of the vibration member 600 of each of the plurality of vibration devices 500, and can have multi-channel sound output characteristics.

[0636] The device 5 according to the fifth exemplary embodiment of this disclosure may include a vibration device 500 that vibrates in a state where it receives prestress (or pretension) or is bent into a curved shape. Therefore, the second moment of inertia may be increased, or the vibration direction of the vibration device 500 may be unidirectional, thereby enhancing the acoustic characteristics and / or sound pressure level characteristics of the sound generated by the vibrating member 600 vibrating based on the vibration of the vibration device 500. The device 5 according to the fifth exemplary embodiment of this disclosure may vibrate the vibrating member 600 to output sound based on the vibration of each of the plurality of vibration devices 500. Therefore, sound can be output, for example, stereo or stereophonic sound with enhanced acoustic characteristics and / or sound pressure level characteristics, and may have multi-channel sound output characteristics.

[0637] Figure 39 It is along Figure 36 Another example cross-sectional view taken from line VI-VI' shown. Figure 39 Examples are given of the direction Figures 36 to 38 The example embodiment of device 5 with an added housing is shown. Therefore, in the description Figure 39 In this case, other components besides the housing and related elements are indicated by similar reference numerals, and their repeated descriptions may be omitted for the sake of brevity.

[0638] Reference Figure 39 The device 5 according to the fifth exemplary embodiment of the present invention may further include a housing 950.

[0639] The housing 950 may be disposed on the rear surface of the support member 300. The housing 950 may be connected to or coupled to the rear surface of the support member 700 to cover the vibrating device 500. For example, the housing 950 may be connected to or coupled to the rear surface of the rear portion 710 of the support member 700 via a connecting member 951. The housing 950 may form an enclosed space covering or surrounding the vibrating device 500 within the rear surface of the support member 700. For example, the housing 950 may form an enclosed space covering or surrounding the vibrating device 500 within the rear surface of the rear portion 710 of the support member 700. For example, the housing 950 may be a sealing member, a sealing cover, a sealing box, or a speaker enclosure, but embodiments of this disclosure are not limited thereto. The enclosed space may be an air gap, a vibration space, a sound space, or a resonance chamber, but embodiments of this disclosure are not limited thereto.

[0640] The housing 950 may comprise one or more materials, including metallic materials and non-metallic materials (or composite non-metallic materials). For example, the housing 950 may comprise one or more materials selected from metallic materials, plastics, and wood, but the embodiments disclosed herein are not limited thereto.

[0641] When the curved portion 750 of the support member 700 or the vibrating device 500 vibrates, the housing 950 according to an exemplary embodiment of the present disclosure can retain the impedance component acting on the curved portion 750 of the support member 700 based on air. For example, the air surrounding the support member 700 can resist the vibration of the curved portion 750 of the support member 700 and can be used as an impedance component having a frequency-based induced resistance component and a drag component. Therefore, the housing 950 can be constructed in the rear surface of the support member 700 to form an enclosed space surrounding the vibrating device 500, thus retaining the impedance component (or air impedance or elastic impedance) acting on the curved portion 750 of the support member 700 based on air. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be enhanced, and the sound quality of the high-pitched vocal cords can be enhanced.

[0642] In the device 5 according to the fifth exemplary embodiment of the present disclosure, the housing 950 can enhance the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords and enhance the sound quality of the high-pitched vocal cords.
