[0149] Throughout the accompanying drawings and detailed description, unless otherwise stated, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustration, and convenience, the dimensions, lengths, and thicknesses of these layers, regions, and elements, and their depictions, may be exaggerated. Detailed Implementation

[0150] Reference will now be made to embodiments of this disclosure in detail, examples of which are illustrated in the accompanying drawings. In the following description, detailed descriptions of well-known functions or configurations may be omitted for brevity where such descriptions might unnecessarily obscure aspects of this disclosure. The progression of the described processing steps and / or operations is exemplary; however, the order of steps and / or operations is not limited to the order set forth herein and may be varied, except for steps and / or operations that must occur in a specific order.

[0151] Unless otherwise stated, the same reference numerals may denote the same components even when shown in different figures. In one or more aspects, unless otherwise stated, the same components (or components with the same name) in different figures may have the same or substantially the same function and characteristics. The names of the various components used in the following explanation are chosen for convenience only and may therefore differ from those used in actual products.

[0152] The advantages and features of this disclosure and its implementation methods are illustrated by referring to the accompanying drawings. However, this disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure is thorough and complete and fully conveys the scope of this disclosure to those skilled in the art.

[0153] The shapes, dimensions, areas, scales, angles, and numbers disclosed in the accompanying drawings to describe embodiments of this disclosure are merely examples, and therefore, this disclosure is not limited to the details shown.

[0154] When terms such as “comprising,” “having,” “including,” “constituting,” “forming,” “component,” etc. are used, one or more other elements may be added unless terms such as “only” are used. The terminology used in this disclosure is for describing particular implementations only and is not intended to limit the scope of this disclosure. The terminology used herein is for describing exemplary implementations only and is not intended to limit the scope of this disclosure. Unless the context clearly specifies otherwise, singular terms may include plural forms. The word “exemplary” is used to indicate that it is used as an example or illustration. An implementation is an exemplary implementation. An aspect is an exemplary aspect. Any implementation described herein as an “example” is not necessarily to be construed as superior to other implementations.

[0155] In one or more aspects, elements, features, or corresponding information (e.g., grade, range, size, dimensions, etc.) are interpreted as including a range of errors or tolerances, even if no explicit description of such errors or tolerances is provided. Ranges of errors or tolerances can be caused by a variety of factors (e.g., process factors, internal or external influences, noise, etc.). Furthermore, the word "can" encompasses all meanings of "able to".

[0156] When describing positional relationships, if the positional relationship between two parts is described using terms such as "above," "over," "below," "upper," "lower," "below," "near," "closer," "adjacent," "beside," "next to," etc., then one or more other parts may be located between the two parts, unless further qualifiers such as "immediately," "directly," or "tightly" are used. For example, when a structure is described as being located "above," "over," or "below," "above," "below," "near," "closer," "adjacent," "beside," or "next to" another structure, the description should be interpreted to include situations where the structures are in contact with each other and situations where one or more additional structures are arranged between them. Furthermore, the terms "front," "rear," "back," "left," "right," "top," "bottom," "down," "up," "upper," "lower," "above," "below," "lower," "column," "row," "vertical," "horizontal," etc., refer to any frame of reference.

[0157] When describing temporal relationships, when the temporal order is described as such as "after", "following", "next", "before", "before", "in front", etc., it may include cases where they are not consecutive or sequential, unless more restrictive terms such as "only", "immediately", or "directly" are used.

[0158] It should be understood that although the terms "first," "second," etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element may be a second element without departing from the scope of this disclosure, and similarly, a second element may be a first element. Furthermore, the terms "first element," "second element," etc., may be arbitrarily named as convenient for those skilled in the art without departing from the scope of this disclosure. The terms "first," "second," etc., may be used to distinguish components, but the function or structure of a component is not limited by the serial number preceding the component or the component name.

[0159] In describing the elements of this disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to identify the corresponding element from other elements, and the elements, basis, order, or number of these terms should not be limited by the elements, basis, order, or number of elements not used to define the elements.

[0160] The expression “connected,” “joined,” or “adhered” to another element or layer can mean not only directly connecting, joining, or adhering to another element or layer, but also indirectly connecting or adhering to another element or layer where one or more intermediate elements or layers are disposed or inserted between the elements or layers, unless otherwise stated.

[0161] For expressions such as "contact" or "overlap" between an element or layer and another element or layer, the element or layer may not only directly contact or overlap with another element or layer, but also indirectly contact or overlap with another element or layer, wherein one or more intermediate elements or layers are set or inserted between elements or layers, unless otherwise specified.

[0162] The term "at least one" should be understood to include any and all combinations of one or more of the associated listed items. For example, "at least one of the first, second, and third items" means a combination of all items proposed from two or more of the first, second, and third items, as well as only one of the first, second, or third items.

[0163] The expressions for the first, second, and / or third element should be understood as one of the first, second, and third elements, or any or all combinations of the first, second, and third elements. For example, A, B, and / or C can refer to only A; only B; only C; any or some combinations of A, B, and C; or all of A, B, and C. Furthermore, the expression "element A / element B" can be understood as element A and / or element B.

[0164] In one or more respects, unless otherwise stated, the terms “between” and “among” may be used interchangeably. For example, the expression “between multiple elements” can be understood as “among multiple elements.” In another example, the expression “among multiple elements” can be understood as “among multiple elements.” In one or more examples, the number of elements may be two. In one or more examples, the number of elements may be more than two.

[0165] In one or more respects, unless otherwise stated, the phrases “mutually” and “each other” may be used interchangeably. For example, the expression “mutually different” can be understood as “different from each other.” In another example, the expression “different from each other” can be understood as “different from each other.” In one or more examples, the number of elements involved in the above expressions may be two. In one or more examples, the number of elements involved in the above expressions may be more than two.

[0166] In one or more respects, unless otherwise stated, the phrases “one or more of…” and “one or more of…” may be used interchangeably. In one or more respects, unless otherwise stated, the term “nth” or “nth one” may refer to “nth” or “nth one” (e.g., the second, where n is 2), or “nth” or “nth one” (e.g., the third, where n is 3), and n may be a natural number.

[0167] Features of the various embodiments of this disclosure can be partially or entirely linked or combined with each other, and can be interoperably linked or driven differently. Embodiments of this disclosure can be performed independently of each other, or can be performed together in a commonly related or related relationship. In one or more aspects, components of each device according to various embodiments of this disclosure are operably linked and configured.

[0168] Unless otherwise defined, the terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the exemplary embodiments pertain. It should be further understood that terms, such as those defined in common dictionaries, should be interpreted as having a meaning consistent with their meaning in the relevant technical context, and should not be interpreted in an idealized or overly formative sense, unless otherwise expressly defined herein.

[0169] In the following, devices, vibration devices, and vehicles including such devices and vibration devices according to various exemplary embodiments of the present disclosure are described in detail with reference to the accompanying drawings. For reference numerals of elements in each drawing, although the same elements may be shown in other drawings, the same reference numerals may refer to the same elements unless otherwise stated.

[0186] The vibration device 500 can be connected to or attached to the support portion 300. The vibration device 500 can have a non-planar (or non-flat) structure via the support portion 300. For example, the vibration device 500 can be configured with a curved shape or curved structure via the support portion 300. For example, the vibration device 500 can be positioned in a state where prestress is applied to it via the support portion 300.

[0187] 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.

[0188] Each of the first vibration device 500-1 and the second vibration device 500-2 can be a membrane vibration device or a membrane-type 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 cover member 130. For example, the first vibration device 500-1 and the second vibration device 500-2 can be disposed parallel to the first central line CL1 between them. For example, the first vibration device 500-1 and the second vibration device 500-2 can be configured to have a symmetrical structure (or a bilaterally symmetrical structure) or an asymmetrical structure (or a bilaterally asymmetrical structure) with respect to the first central line CL1 of the cover member 130.

[0189] The first vibration device 500-1 can be disposed at the first rear peripheral portion of the cover member 130. For example, the first vibration device 500-1 can be disposed at the first support portion 310 in the first region 100A1 of the cover member 130. For example, the first vibration device 500-1 can be disposed close to the first rear peripheral portion of the cover member 130.

[0190] 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 can be aligned with or positioned at the second central line CL2 of the cover member 130. For example, the central portion (or central part or intermediate part) CP of the first vibration device 500-1 can be disposed on the second central line CL2 within the first region 100A1 of the cover member 130, between the first central line CL1 of the cover member 130 and the first sidewall (or first short side or first side) of the cover member 130. For example, the first vibration device 500-1 can be configured within the first region 100A1 of the cover member 130, closer to the first sidewall of the cover member 130 than the first central line CL1 of the cover member 130, or the distance to CL1 is greater than the distance to the first sidewall.

[0191] According to another exemplary embodiment of this disclosure, the central portion (or central or intermediate portion) CP of the first vibration device 500-1 may be spaced apart from the second central line CL2 of the cover member 130. For example, the central portion (or central or intermediate portion) CP of the first vibration device 500-1 may be positioned in a first sub-region 100B1 of the first region 100A1. For example, the central portion (or central or intermediate portion) CP of the first vibration device 500-1 may be positioned at the first sub-region 100B1 of the first region 100A1, spaced apart from the second central line CL2 of the cover member 130 by a predetermined separation distance ΔL. 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.

[0192] In another embodiment, a portion or area of ​​the first vibration device 500-1 disposed in the first sub-region 100B1 is larger than a portion or area disposed in the second sub-region 100B2. For example, when the device according to an exemplary embodiment of the present disclosure is applied to a display device, the lowest portion (or the lowest end or lowest part) of the second sub-region 100B2 of the cover member 130 can act as a support portion and therefore can be a free end that is able to move or vibrate freely from the lowest portion of the second sub-region 100B2 toward the uppermost portion of the first sub-region 100B1 during vibration of the cover member 130. Therefore, when the central portion CP of the first vibration device 500-1 is positioned at the first sub-region 100B1 spaced apart from the second central line CL2 of the cover member 130, the vibration width (or displacement width) of the first vibration device 500-1 corresponding to the same drive signal can be increased more than when the central portion CP of the first vibration device 500-1 is positioned at the second central line CL2 of the cover member 130. As a result, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated based on the vibration of the first vibration device 500-1 can be enhanced.

[0193] The second vibration device 500-2 can be disposed at the second rear peripheral portion of the cover member 130. For example, the second vibration device 500-2 can be disposed at the second support portion 320 in the second region 100A2 of the cover member 130. For example, the second vibration device 500-2 can be disposed close to the second rear peripheral portion of the cover member 130.

[0194] 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 can be aligned with or positioned at the second central line CL2 of the cover member 130. For example, the central portion (or central part or intermediate part) CP of the second vibration device 500-2 can be disposed on the second central line CL2 within the second region 100A2 of the cover member 130, between the first central line CL1 of the cover member 130 and the second sidewall (or second short side or second side) of the cover member 130. For example, the second vibration device 500-2 can be disposed within the second region 100A2 of the cover member 130, closer to the second sidewall of the cover member 130 than the first central line CL1 of the cover member 130.

[0195] The first vibration device 500-1 and the second vibration device 500-2 are symmetrically arranged with respect to the first central line CL1. Both have similar distances from their respective sidewalls and similar spacing from the first central line CL1.

[0196] According to another exemplary embodiment of this disclosure, the central portion (or central or intermediate portion) CP of the second vibration device 500-2 may be spaced apart from the second central line CL2 of the cover member 130. For example, the central portion (or central or intermediate portion) CP of the second vibration device 500-2 may be positioned in the second sub-region 100B2 of the second region 100A2. For example, the central portion (or central or intermediate portion) CP of the second vibration device 500-2 may be positioned at the first sub-region 100B1 of the second region 100A2, spaced apart from the second central line CL2 of the cover member 130 by a predetermined separation distance ΔL. 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.

[0197] Each of the first vibration device 500-1 and the second vibration device 500-2 can vibrate based on a drive signal including a sound signal (or voice signal) or, for example, a sound signal and a tactile feedback signal input from the outside, to cause the vibrating member 100 to vibrate, and thus, sound S can be generated based on the vibration of the vibrating member 100, or tactile feedback (or tactile vibration) can be generated in response to a user touch.

[0198] 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 the vibrating member 100 driven by the 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, 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 the display panel) as a vibrating plate for generating (or outputting) sound to output sound in the forward direction of the vibrating member 100 or in the forward direction of the screen, and thus can transmit more accurate sound, thereby improving sound quality and / or sound and enhancing the viewer's immersion.

For example, the connecting member 114 may include an acrylic adhesive member that has relatively better adhesion and hardness than a urethane adhesive member, allowing vibrations of the guide member 115 to 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 adhesive layer or an acrylic adhesive resin cured layer.

[0226] According to an exemplary embodiment of the present disclosure, the front surface of the coupling member 114 can be disposed at the second substrate 111b or the first polarizing member 111c of the display panel 111. The coupling member 114 can be directly coupled to the rear peripheral portion of the second substrate 111b to enhance adhesion to the display panel 111. For example, the coupling 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.

[0227] 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 portion 113. The connecting member 114 may be disposed in the guide frame 115a of the guide member 115 in a four-sided closed shape or a closed-loop shape, 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 rearmost surface of the display panel 111 facing each other and the uppermost surface of the backlight portion 113, with an opening portion of the guide member 115 between the rearmost surface of the display panel 111 and the uppermost surface of the backlight portion 113, thereby preventing or minimizing leakage (or loss) of sound pressure transmitted to the sound transmission space STS. The sound transmission space STS may also serve as a sound pressure level generating space based on the vibration of the backlight portion 113, or a panel vibration space that allows the vibration of the display panel 111 to be smoothly performed. 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.

[0228] The cover member 130 can be configured to support the display member 110. The cover member 130 may include a rear portion 131 and a side portion 135.

[0229] The rear portion 131 can be disposed on the rear surface of the display member 110. The rear portion 131 may include a substrate surface (or support surface or bottom surface) 130a that supports the display member 110. The rear portion 131 can be related to the above-mentioned... Figure 1 and 2 The latter part 131 of the description is basically the same, so its repeated description can be omitted for brevity.

[0230] Side portion 135 may be connected to the peripheral portion of rear portion 131 and may be configured to support display member 110. Side portion 135 may be configured to have a predetermined height along the peripheral portion of rear portion 131, and thus, may provide receiving space above substrate surface 130a of rear portion 131. For example, side portion 135 may be bent from the peripheral portion of rear portion 131. For example, side portion 135 may be a sidewall portion or a transverse cover portion, and embodiments of this disclosure are not limited thereto.

[0231] A support portion 300 may be disposed on the rear surface of the vibrating member 100. The support portion 300 may be disposed on the rear surface of the cover member 130 disposed on the vibrating member 100 and may be configured to support the vibrating device 500. The support portion 300 may support the vibrating device 500 such that the shape of the vibrating device 500 is non-planar (or non-flat). For example, the support portion 300 may be configured to apply prestress to the vibrating device 500. For example, the support portion 300 may be configured to apply tensile stress only to the vibrating device 500. For example, the support portion 300 may include a bent portion 315 having a bent shape (or bent structure) for applying tensile stress only to the vibrating device 500.

[0232] The support portion 300 according to an exemplary embodiment of the present disclosure may include a first support portion 310 and a second support portion 320.

[0233] Each of the first support portion 310 and the second support portion 320 may include a shape or structure for applying prestress to the vibration device 500. For example, each of the first support portion 310 and the second support portion 320 may include a bent portion 315 configured to apply tensile stress only to the vibration device 500.

[0234] Each of the first support portion 310 and the second support portion 320 may include a pair of first support members 311 and 312.

[0235] The pair of first support members 311 and 312 may be parallel to each other along a first direction X. Each of the pair of first support members 311 and 312 may include a curved portion 315 with a predetermined curvature.

[0236] The curved portion 315 may have a curved structure having a curvature (or a single curvature) without an inflection point. For example, the curved portion 315 may have a structure that projectes outward from the rear portion 131 of the cover member 130. For example, the curved portion 315 may have a single convex curved shape with a certain curvature. For example, the pair of first support members 311 and 312 including the curved portion 315 may be curved support portions, support rods, protruding rods, curvature guide portions, curved structures, curved structures, curved protrusions, arcuate portions, or stress-applying portions, but embodiments of this disclosure are not limited thereto.

[0237] According to an exemplary embodiment of this disclosure, the height (or distance) H1 between the curved portion 315 of the support portion 300 and the vibrating member 100 can gradually increase from the outer periphery of the curved portion 315 toward the central portion of the curved portion 315. According to an exemplary embodiment of this disclosure, the height H1 of the curved portion 315 can be set within a range that allows prestress to be applied to the vibrating device 500. For example, the height H1 of the curved portion 315 can be from 2 mm to 200 mm, but embodiments of this disclosure are not limited thereto, and the height H1 of the curved portion 315 can vary based on the dimensions of the vibrating device 500. When the height H1 of the curved portion 315 is less than 2 mm, due to the relatively small curvature, it may be difficult or insufficient to apply prestress to the vibrating device 500, and therefore, there may be no effect. When the height H1 of the curved portion 315 is greater than 200 mm, due to the relatively large curvature and thickness of the device or display device, the reliability of the vibrating device 500 may decrease, and therefore, it may be difficult to achieve a slim profile.

[0238] The pair of first support members 311 and 312 may be disposed parallel to the first direction X at the rear portion 131 of the cover member 130. Each of the pair of first support members 311 and 312 may support a pair of first peripheral portions of the vibrating device 500 parallel to the first direction X. Therefore, the vibrating device 500 may be bent into a curved shape by means of the curved portion 315 of each of the pair of first support members 311 and 312. For example, the vibrating device 500 may be bent into a curved shape by means of the curved surface of the curved portion 315 of each of the pair of first support members 311 and 312. Each of the pair of first support members 311 and 312 may include an arcuate shape with a predetermined curvature between a pair of short sides 311a and 311b parallel to the second direction Y.

[0239] Each of the first support portion 310 and the second support portion 320 may also include a pair of second support members (or support rods) 321 and 322.

[0240] The pair of second support members 321 and 322 may be parallel to each other along the second direction Y. Each of the pair of second support members 321 and 322 may be connected to or disposed between the pair of first support members (or support rods) 311 and 312. Each of the pair of second support members 321 and 322 may be disposed at the rear portion 131 of the cover member 130 parallel to the second direction Y. Each of the pair of second support members 321 and 322 may support a pair of second peripheral portions of the periphery of the vibration device 500 parallel to the second direction Y.

[0241] exist Figure 4The illustration shows each of the pair of first support members 311 and 312 and each of the pair of second support members 321 and 322 spaced apart from each other, but embodiments of this disclosure are not limited thereto. For example, each of the pair of first support members 311 and 312 and each of the pair of second support members 321 and 322 may be provided as a single body having a frame shape.

[0242] According to an exemplary embodiment of this disclosure, when the vibration device 500 has a rectangular shape including a long side and a short side, the curved portion 315 of each of the pair of first support members 311 and 312 can support the peripheral portion of the short side of the vibration device 500 in a curved shape. For example, when each of the pair of first support members 311 and 312 is arranged parallel to the first direction X at the rear portion 131 of the cover member 130 and supports the peripheral portion of the short side of the vibration device 500, the long side of the vibration device 500 can be arranged parallel to the second direction Y. For example, when each of the pair of first support members 311 and 312 is arranged parallel to the second direction Y at the rear portion 131 of the cover member 130 and supports the peripheral portion of the short side of the vibration device 500, the long side of the vibration device 500 can be arranged parallel to the first direction X.

[0243] According to exemplary embodiments of this disclosure, each of the first support portion 310 and the second support portion 320 may include one or more of a metallic material, a plastic material, and an elastic material, but embodiments of this disclosure are not limited thereto. For example, the metallic material may be electroplated galvanized sheet iron, but embodiments of this disclosure are not limited thereto. The plastic material may be a composite of polycarbonate (PC) resin and acrylonitrile-butadiene-styrene (ABS) resin, but embodiments of this disclosure are not limited thereto. For example, the elastic material may be a foam pad. For example, the elastic material may include epoxy resin, acrylic resin, silicone resin, or polyurethane resin, but embodiments of this disclosure are not limited thereto.

[0244] According to an exemplary embodiment of this disclosure, each of the first support portion 310 and the second support portion 320 may be coupled or attached to the rear surface of the vibrating member 100 by an adhesive member. For example, each of the first support portion 310 and the second support portion 320 may be coupled or attached to the rear portion 131 of the cover member 130 by an adhesive member.

[0245] According to an exemplary embodiment of this disclosure, each of the first support portion 310 and the second support portion 320 may be connected or fastened to the rear surface of the vibrating member 100 by a fastening member such as a screw or nut. For example, each of the first support portion 310 and the second support portion 320 may be connected or fastened to the rear portion 131 of the cover member 130 by a fastening member.

[0246] According to an exemplary embodiment of this disclosure, each of the first support portion 310 and the second support portion 320 may comprise a metallic material and may be connected or fixed to the rear surface of the vibrating member 100 by welding or the like. For example, each of the first support portion 310 and the second support portion 320 may be connected or fixed to the rear portion 131 of the cover member 130 by welding or the like.

[0247] According to exemplary embodiments of the present disclosure, each of the first support portion 310 and the second support portion 320 may comprise a metallic material and may be integrated into or provided together with the rear surface of the vibrating member 100 as a single body without a separate intermediate medium material. For example, each of the first support portion 310 and the second support portion 320 may be integrated into or provided together with the rear portion 131 of the cover member 130 as a single body without a separate intermediate medium material.

[0248] The vibration device 500 can be coupled or attached to the curved portion 315 of the support portion 300. For example, the vibration device 500 can be coupled or attached to the curved portion 315 based on the curvature of the curved portion 315 to have an isometric shape (or conformal shape), but embodiments of this disclosure are not limited thereto. For example, the vibration device 500 can be coupled or attached to the curved portion 315 to have an isometric shape that conforms to the curvature profile of the curved portion 315. For example, the vibration device 500 can be coupled or attached to the curved portion 315 to have a non-isometric shape (or non-conformal shape) that is not based on the curvature of the curved portion 315 or has a curvature different from the curvature of the curved portion 315. For example, the vibration device 500 can be coupled or attached to the curved portion 315 to have a non-isometric shape that is not based on the curvature profile of the curved portion 315 or has a curvature different from the curvature of the curved portion 315.

[0249] According to another exemplary embodiment of this disclosure, the vibration device 500 may be coupled to or attached to the curved portion 315 of the support portion 300, and thus may have prestress or receive prestress based on the curved portion 315. For example, the vibration device 500 may be coupled to or attached to the curved portion 315 of the support portion 300, and thus may be maintained in a state where the vibration device 500 has prestress or receives prestress based on the curved portion 315 of the support portion 300. For example, the vibration device 500 may receive tensile stress or tensile stress including the curvature based on the curved portion 315 of the support portion 300. For example, the curved portion 315 of the support portion 300 may be configured to apply tensile stress only to the vibration device 500 in order 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 curved portion 315 of the support portion 300, the vibration characteristics of the vibration device 500 may be reduced.

[0250] According to another exemplary embodiment of this disclosure, the vibration device 500 may include a bent state in a curved shape, or may receive prestress (or pre-tension stress) based on the bent portion 315 of the support portion 300, and thus, the second moment of inertia may increase. In the vibration device 500, the number of resonant frequencies occurring during vibration due to the increase in the second moment of inertia may decrease, and thus the number of nodes (or joints) may decrease, 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, and thus the sound pressure level characteristics and / or acoustic characteristics can be enhanced.

[0251] According to another exemplary embodiment of this disclosure, the vibration device 500 can vibrate based on the curved portion 315 of the support portion 300 while the vibration device 500 is bent in a curved shape or receiving prestress (or pre-tension stress). Therefore, its vibration direction (or displacement direction, bending direction, or driving direction) can be implemented as a single direction and the dynamic displacement can extend. Consequently, the sound generated by the vibration of the vibration device 500 can be concentrated in a direction toward the center of the curved portion 315, and the sound pressure level transmitted to the vibration member 100 can be increased or amplified. Therefore, the sound characteristics and / or sound pressure level characteristics generated by the vibration of the vibration member 100 can be enhanced.

[0252] The first vibration device 500-1 of the vibration device 500 can be coupled to or attached to the curved portion 315 of the first support portion 310. The first vibration device 500-1 can be coupled to or attached to the curved portion 315 to have an isoangular shape based on the curvature of the curved portion 315, 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 curved portion 315 to have an isoangular shape with a profile conforming to the curvature of the curved portion 315. For example, the first vibration device 500-1 can be coupled to or attached to the curved portion 315 to have a non-isoangular shape, which is not based on the curvature of the curved portion 315 or has a curvature different from the curvature of the curved portion 315. For example, the first vibration device 500-1 can be coupled to or attached to the curved portion 315 to have a non-isoangular shape, which is not based on the profile of the curvature of the curved portion 315. Therefore, the first vibration device 500-1 can vibrate in a state where it receives prestress (or pre-tension stress) or is bent in a curved shape based on the bending portion 315, thereby generating or outputting sound or sound waves. Therefore, the first region of the vibration member 100 overlapping with the first vibration device 500-1 can receive sound or sound waves generated based on the vibration of the first vibration device 500-1 to vibrate, and thus can generate or output sound and / or tactile feedback.

[0253] The second vibration device 500-2 of the vibration device 500 can be coupled or attached to the curved portion 315 of the second support portion 320. The second vibration device 500-2 can be coupled or attached to the curved portion 315 to have an isoangular shape based on the curvature of the curved portion 315, but embodiments of this disclosure are not limited thereto. For example, the second vibration device 500-2 can be coupled or attached to the curved portion 315 to have an isoangular shape with a profile conforming to the curvature of the curved portion 315. For example, the second vibration device 500-2 can be coupled or attached to the curved portion 315 to have a non-isoangular shape, which is not based on the curvature of the curved portion 315 or has a curvature different from the curvature of the curved portion 315. For example, the second vibration device 500-2 can be coupled or attached to the curved portion 315 to have a non-isoangular shape, which is not based on the profile of the curvature of the curved portion 315. Therefore, the second vibration device 500-2 can vibrate in a state where it receives prestress (or pre-tension stress) or is bent in a curved shape based on the bending portion 315, thereby generating or outputting sound or sound waves. Therefore, the second region of the vibrating member 100 that overlaps with the second vibration device 500-2 can receive sound or sound waves generated based on the vibration of the second vibration device 500-2 to vibrate, and thus can generate or output sound and / or tactile feedback.

[0254] The device 1 according to the first exemplary embodiment of the present disclosure may further include a gap space GS disposed between the vibrating member 100 and the vibrating device 500 by a support portion 300.

[0255] The gap space GS can be provided between the rear portion 131 of the cover member 130 and the vibration device 500 via the support portion 300. For example, the gap space GS can be provided between the curved portion 315 and the reflector 113b of the backlight portion 113. The gap space GS can include a space for generating sound or sound pressure level based on the vibration of the vibration device 500, a space for smoothly executing the vibration of the vibration device 500, or a space or path for sound waves generated based on the vibration of the vibration device 500 to propagate to the vibration 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 generating portion, a sound generating 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.

[0256] The vibration device 500 can vibrate in a state where it receives prestress (or pre-tension stress) or is bent in a curved shape based on the bending portion 315 of the support portion 300, and therefore, sound or sound waves can be generated or output in the gap space GS. Thus, the vibration member 100 can vibrate based on the sound (or sound waves) in the gap space GS to generate or output sound and / or tactile feedback. For example, in the display member 110, sound (or sound waves) generated by the vibration of the backlight portion 113 based on the vibration of the cover member 130 can be output 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 in the sound transmission space STS.

[0257] 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 pre-tension stress) or is bent based on the bending shape of the support portion 300, and thus the second moment of inertia in the vibration device 500 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, which vibrates based on the vibration of the vibration device 500.

[0258] Figure 5 This is a perspective view illustrating a vibration device according to an exemplary embodiment of the present disclosure. Figure 5 Examples Figure 2 and Figure 3 The vibration device shown is either the first vibration device or the second vibration device.

[0259] Reference Figure 5The vibration device 500 or the first vibration device 500-1 and the second vibration device 500-2 according to the first exemplary embodiment of the present disclosure may include a vibration generator 510, a first connecting member 520, a plate 530 and a second connecting member 540.

[0260] The vibration generator 510 can be configured to vibrate (or displace or drive) the vibrating member 100 based on a drive signal (or electrical signal or voice signal) applied thereto. For example, the vibration generator 510 can 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 embodiments of this disclosure are not limited thereto.

[0261] 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 or drive) based on the vibration (or displacement or drive) of the piezoelectric material generated by a drive signal applied thereto, or may cause the vibration member 100 to vibrate (or displace or drive). For example, the vibration generator 510 may vibrate (or displace or drive) as contraction and / or expansion alternately repeat via the piezoelectric effect (or piezoelectric properties). For example, the vibration generator 510 may vibrate (or displace or drive) in the vertical direction (or thickness direction) Z because contraction and / or expansion alternately repeat via the inverse piezoelectric effect.

[0262] 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 that includes a curved surface.

[0263] The vibration generator 510 according to an exemplary embodiment of the present 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, wherein the first length and the second length are the same, or it may include a rectangular shape, wherein the first length and the second length are different.

[0264] The first connecting member 520 may be connected to or coupled to one of a first surface and a second surface of the vibration generator 510, the second surface being different from (or opposite to) the first surface. For example, in the vibration generator 510, the first surface may be a top surface, a front surface, a forward surface, or an upper surface. In the vibration generator 510, the second surface may be a lower surface, a rear surface, a bottom surface, a back surface, or a rearward surface. For example, the first connecting member 520 may be an adhesive member or a first adhesive member.

[0265] The first connecting member 520 according to an exemplary embodiment of the present disclosure may include an adhesive layer (or sticky layer) that is relatively strong in terms of adhesion or bonding force. For example, the first connecting member 520 may include double-sided tape, double-sided foam pads, or adhesive sheets. For example, when the first connecting member 520 includes an adhesive sheet (or adhesive layer), the first connecting member 520 may consist only of an adhesive layer or sticky layer without a base member such as a plastic material.

[0266] The adhesive layer (or adhesive layer) of the first 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 not limited thereto. The adhesive layer (or adhesive layer) of the first connecting member 520 according to another exemplary embodiment of the present disclosure may include pressure-sensitive adhesive (PSA), optically transparent adhesive (OCA), or optically transparent resin (OCR), but the embodiments of the present disclosure are not limited thereto.

[0267] Plate 530 can be attached to or attached to the first connecting member 520. For example, plate 530 can have a size or area larger than that of the vibration generator 510. For example, the central portion of plate 530 can be aligned with or positioned at the central portion of the vibration generator 510. Plate 530 can be attached to or attached to the second connecting member 540. Figure 3 On the curved portion 315 of the support portion 300 shown.

[0268] According to an exemplary embodiment of this disclosure, the vibration generator 510 may have a modulus greater than the modulus (or Young's modulus) of each of the first connecting member 520, the plate 530, and the second connecting member 540, or may have a modulus equal to the modulus (or Young's modulus) of each of the first connecting member 520 and the second connecting member 540 and greater than the modulus (or Young's modulus) of the plate 530. Therefore, the vibration generator 510 may be bent in a curved shape. For example, the plate 530 may have a modulus smaller than that of the vibration generator 510. Thus, the vibration generator 510 can be bent by the first connecting member 520, the plate 530, and the second connecting member 540 in a shape corresponding to the curved portion 315 of the support portion 300, thereby enhancing the reliability of sound reproduction.

[0269] Furthermore, the vibration generator 510 according to the exemplary embodiment of this disclosure can enhance the adhesion of the first connecting member 520, the plate 530, and the second connecting member 540 to the curved portion 315 of the support portion 300, thereby enhancing the reliability of sound reproduction and improving the sound characteristics and / or sound pressure level characteristics of the bass vocal cords. For example, when the modulus of the plate 530 is greater than that of the vibration generator 510, the vibration generator 510 may be difficult to bend in the shape corresponding to the curved portion 315 of the support portion 300, and the adhesion of the first connecting member 520, the plate 530, and the second connecting member 540 to the curved portion 315 of the support portion 300 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.

[0270] According to an exemplary embodiment of this disclosure, plate 530 may include a material having material properties suitable for bending the vibration generator 510 into a curved shape. For example, plate 530 may include a material with a stiffness less than the bending stiffness of the vibration generator 510. Plate 530 may include one or more materials selected from metal, glass, plastic, rubber, fiber, leather, wood, cloth, and paper. For example, plate 530 may be a support plate, stiffening plate, transmission plate, intermediate plate, or vibration transmission plate, but embodiments of this disclosure are not limited thereto.

[0271] like Figure 5 As shown, the second connecting member 540 can connect or attach the plate 530 to the curved portion 315 of the support portion 300. For example, the second connecting member 540 can be disposed between the curved portion 315 of the support portion 300 and the plate 530. For example, the second connecting member 540 can be inserted between the curved portion 315 of the support portion 300 and the front peripheral portion of the plate 530.

[0272] The second connecting member 540 may include an adhesive layer (or sticky layer) that is relatively strong in terms of adhesion or bonding force. The second connecting member 540 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 greater modulus (or adhesion or hardness) than the second connecting member 540, such that the plate 530 and the vibration generator 510 bend smoothly in a curved shape.

[0273] The second connecting member 540 according to an exemplary embodiment of the present disclosure may include an opening portion 541. Therefore, the second connecting member 540 may be disposed or inserted between the curved portion 315 of the support portion 300 and the front peripheral portion of the plate 530. For example, the second connecting member 540 may be configured as a quadrilateral strip shape including the opening portion 541.

[0274] According to another exemplary embodiment of this disclosure, the second connecting member 540 may have a structure in which the second connecting member 540 is divided into four or more parts to correspond to or overlap with the front peripheral portion of the plate 530.

[0275] In the vibration device 500 or the first vibration device 500-1 and the second vibration device 500-2 according to the exemplary embodiments of the present disclosure, the vibration generator 510 can be connected or attached to the curved portion 315 of the support portion 300 via the first connecting member 520, the plate 530 and the second connecting member 540, and thus can be in a state where the vibration generator 510 receives prestress (or pre-tension stress) or is bent in a curved shape based on the bending shape of the curved portion 315 (or including this state). Therefore, the vibration generator 510 can vibrate in a state where the vibration generator 510 receives prestress (or pre-tension stress) or is bent in a curved shape, and thus, the second moment of inertia can be increased or the vibration direction can be implemented in a single direction.

[0276] The vibration device 500 or the first vibration device 500-1 and the second vibration device 500-2 according to the first exemplary embodiment of the present disclosure may further include a pad 550.

[0277] The pad 550 may be coupled to or attached to the second surface of the vibration generator 510. For example, the pad 550 may be coupled to or attached to the central portion of the second surface of the vibration generator 510. The pad 550 may have a size smaller than or equal to that of the vibration generator 510. For example, the pad 550 may have a polygonal column shape or a circular column shape, but embodiments of this disclosure are not limited thereto.

[0278] The pad 550 according to an exemplary embodiment of the present disclosure may include a material having a stiffness less than that of the vibration generator 510. The pad 550 according to another exemplary embodiment of the present disclosure may include an elastic material that may act as a mass (or counterweight) on the vibration generator 510.

[0279] According to an exemplary embodiment of this disclosure, the pad 550 can increase the mass of the vibration generator 510, and thus can reduce 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 mass caused by the pad 550, resulting in the lowest resonant frequency (or lowest natural frequency). Therefore, the sound characteristics and / or sound pressure level characteristics of the bass vocal cords generated based on the vibration of the vibration device 500 can be enhanced. For example, the pad 550 can be a resonant pad, a mass member, a counterweight, or a counterweight member. For example, the bass vocal cords can be about 300 Hz or about 500 Hz or lower, but embodiments of this disclosure are not limited thereto.

[0280] Figure 6 It is along Figure 2 Another cross-sectional view taken from line I-I' in the diagram. Figure 7 This is an example Figure 6 The rear perspective view of the cover component shown. Figure 6 and Figure 7 An apparatus according to a second exemplary embodiment of the present disclosure is illustrated. Figure 6 and Figure 7 Examples are shown in the reference above. Figures 1 to 5 An exemplary embodiment of the described device is further provided with holes.

[0281] Reference Figure 6 and Figure 7 According to a second exemplary embodiment of the present disclosure, the device 2 may include a vibration member 100, a support portion 300, and a vibration device 500.

[0282] The vibrating member 100 may include one or more holes 137 overlapping with the support portion 300 or the vibrating device 500. For example, the cover member 130 of the vibrating member 100 may include one or more holes 137 overlapping with the support portion 300 or the vibrating device 500. In addition to one or more holes 137 being disposed at the cover member 130, the vibrating member 100 may be configured with the aforementioned references. Figures 1 to 5 The descriptions are the same or substantially the same, and therefore, in the following description, the same elements, except for one or more holes and related elements, may be referred to by the same or similar reference numerals, and their descriptions may be omitted for brevity.

[0283] The cover member 130 may include one or more holes 137 overlapping with the vibration device 500. One or more holes 137 may be covered by the vibration device 500. For example, one or more holes 137 may be provided... Figure 4 The pair of first support members (or support rods) 311 and 312 shown are positioned between them. For example, one or more holes 137 can be used. Figure 4 The pair of first support members (or support rods) 311 and 312 and the pair of second support members (or support rods) 321 and 322 shown are surrounded.

[0284] One or more holes 137 may be formed at the rear portion 131 of the cover member 130 to overlap with the vibration device 500. For example, one or more holes 137 may be formed to pass through the curved portion 315 of the cover member 130 along a third direction Z. Thus, one or more holes 137 may be an opening, a connecting portion, an opening hole, a connecting hole, a through portion, a through opening, a through hole, a support hole, a slit, a slot, or a sound-passing portion, but 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 cover member 130, or it may be the Z-axis direction in the XYZ axis direction.

[0285] One or more holes 137 according to exemplary embodiments of the present disclosure may have the same shape as the vibration device 500. For example, when the vibration device 500 has a square shape, one or more holes 137 may have a square shape, and when the vibration device 500 has a rectangular shape, one or more holes 137 may have a rectangular shape, but embodiments of the present disclosure are not limited thereto.

[0286] One or more holes 137 may be provided between the vibrating member 100 and the vibrating devices 500-1 and 500-2. Therefore, one or more holes 137 may provide a clearance space GS between the vibrating member 100 and the vibrating devices 500-1 and 500-2. Therefore, with... Figure 3 Compared to the device 1 shown, the gap space GS between the vibrating member 100 and the vibrating device 500 can be expanded to a volume (or space) corresponding to the thickness of the rear portion 131 of the cover member 130 and the size of one or more holes 137. 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 part, a sound-generating 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.

[0287] One or more holes 137 may be provided between the backlight portion 113 of the vibrating member 100 and the vibrating devices 500-1 and 500-2. Therefore, one or more holes 137 can provide a gap space GS between the backlight portion 113 and the vibrating devices 500-1 and 500-2. For example, one or more holes 137 can provide a gap space GS between the reflective sheet 113b of the backlight portion 113 and the vibrating devices 500-1 and 500-2.

[0288] Each of the first vibration device 500-1 and the second vibration device 500-2 of the vibration device 500 can be connected or attached to the first bending portion 315 and the second bending portion 315 to cover one or more holes 137, and can receive prestress (or pre-tension stress) or vibrate in a bent state in the first vibration device 500-1 and the second vibration device 500-2, and thus the second moment of inertia can be increased or the vibration direction can be implemented in a single direction.

[0289] Each of the first vibration device 500-1 and the second vibration device 500-2 of the vibration device 500 can face the rear surface of the vibration member 100 or directly face the rear surface of the vibration member 100 through one or more holes 137. For example, each of the first vibration device 500-1 and the second vibration device 500-2 can face the backlight portion 113 or directly face the backlight portion 113 of the vibration member 100 through one or more holes 137. For example, each of the first vibration device 500-1 and the second vibration device 500-2 can face the reflector 113b of the backlight portion 113 or directly face the reflector 113b of the backlight portion 113 through one or more holes 137. 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 display member 110 of the vibration member 100 through one or more holes 137 or 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 portion 113 of the display member 110 through one or more holes 137 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 display member 110 or the vibrating member 100, and thus, the sound characteristics and / or sound pressure level characteristics generated by the vibration of the display member 110 or the vibrating member 100 can be enhanced. 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 portion 113 based on the sound according to the gap space GS can be output 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 according to the gap space GS.

[0290] 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 pre-tension stress) or is bent in a curved shape, and 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. Additionally, the device 2 according to the second exemplary embodiment of this disclosure may include one or more holes 137 formed in the vibrating member 100 or the cover member 130, and therefore, the sound (or sound waves) generated based on the vibration of the vibrating device 500 can be directly transmitted to the display member 110. Therefore, the transmission efficiency of the vibration can be increased, and the sound characteristics and / or sound pressure level characteristics generated based on the vibration of the vibrating member 100 or the cover member 130 can be further enhanced.

[0291] Figure 8 This is a rear perspective view illustrating a support portion and a cover member according to another exemplary embodiment of the present disclosure. Figure 8 Examples are shown by modifying Figure 7 An exemplary embodiment implemented with the support portion and cover member shown.

[0292] Reference Figure 6 and Figure 8 According to another exemplary embodiment of the present disclosure, the rear surface of the vibration member 100 or the rear portion 131 of the cover member 130 may include a first region 100A1, a second region 100A2, and a third region 100A3. For example, the rear surface of the vibration member 100 or the rear portion 131 of the cover member 130 may include a first region 100A1, a second region 100A2, and a third region 100A3 relative to a first length (or lateral length) parallel to a first direction X.

[0293] The first region 100A1 can be a first rear region, a left region, or a rear left region. The second region 100A2 can be a second rear region, a right region, or a rear right region. The third region 100A3 can be the region between the first region 100A1 and the second region 100A2. For example, the third region 100A3 can be a central region including a centerline having a first length of the cover member 130.

[0294] The support portion 300 may include a curved portion 315 disposed in each of the first region 100A1, the second region 100A2, and the third region 100A3 of the rear portion 131 of the cover member 130 or the vibration member 100. For example, the support portion 300 may include a first support portion 310, a second support portion 320, and a third support portion 330 disposed in the first region 100A1, the second region 100A2, and the third region 100A3, respectively, and each support portion includes a curved portion 315.

[0295] Each of the first support portion 310, the second support portion 320, and the third support portion 330 may be coupled to or connected to the rear surface of the vibrating member 100 or the rear portion 131 of the cover member 130, having the same dimensions and shape. Each of the first support portion 310, the second support portion 320, and the third support portion 330 may have a square or rectangular shape. The curved portion 315 of each of the first support portion 310, the second support portion 320, and the third support portion 330 may have the same curvature. The curved portion 315 of each of the first support portion 310, the second support portion 320, and the third support portion 330 may be as described above. Figure 3 and Figure 4 The descriptions are the same or substantially the same, and therefore, repeated descriptions may be omitted for brevity.

[0296] The vibration device 500 may include a first to a third vibration device disposed at a curved portion 315 of each of the first support portion 310, the second support portion 320, and the third support portion 330. Each of the first to third vibration devices may receive prestress (or pre-tension stress) or vibrate in a bent state based on the curvature of the curved portion 315, and thus the second moment of inertia may be increased or the vibration direction may be implemented in a single direction.

[0297] The rear surface of the vibrating member 100 or the cover member 130 may also include one or more holes 137, which overlap with the vibrating device 500 disposed at one or more of the first support portion 310, the second support portion 320, and the third support portion 330. For example, one or more holes 137 may be configured at the rear portion 131 of the cover member 130 to overlap with the vibrating device 500 disposed at the third support portion 330. In addition to forming one or more holes 137 at the rear portion 131 of the cover member 130 to overlap with the vibrating device 500 disposed at the third support portion 330, one or more holes 137 may be formed with reference to the above-mentioned... Figure 6 and Figure 7The descriptions are the same or substantially the same, and therefore repeated descriptions may be omitted for brevity. Thus, sound (or sound waves) generated by the vibration of the vibrating device 500 located at the third support portion 330 can be directly transmitted to the third region 100A3 of the display member 110 through one or more holes 137, and thus, the transmission efficiency of the vibration can be increased, and the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated by the vibration of the third region 100A3 of the display member 110 or the vibrating member 100 can be further enhanced.

[0298] According to an exemplary embodiment of this disclosure, each of the first to third vibration devices disposed at the curved portion 315 of each of the first support portion 310, the second support portion 320, and the third support portion 330 can be configured to generate or output the sound of the vocal cords with the same or substantially the same pitch. Therefore, the device 2 according to a second exemplary embodiment of this disclosure can output stereo sound due to the sound output from each of the left, right, and central (or middle) portions of the vibration member 100 based on the vibration of each of the first to third vibration devices, and can have 3-channel sound output characteristics.

[0299] According to another exemplary embodiment of this disclosure, one or more of the first to third vibrating devices disposed at the curved portion 315 of each of the first support portion 310, the second support portion 320, and the third support portion 330 may be configured to generate or output the sound of vocal cords with different pitches. For example, the third vibrating device 500-3 may be configured to generate or output the sound of low-pitched vocal cords, and each of the first vibrating device 500-1 and the second vibrating device 500-2 may be configured to generate or output the sound of vocal cords with a wider pitch than the third vibrating device 500-3, but the embodiments of this disclosure are not limited thereto. Therefore, the device 2 according to the second exemplary embodiment of this disclosure can achieve, for example, stereo sound by outputting left and right sounds based on the vibration of the vibrating member 100 of each of the first and second vibrating devices, and can enhance the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords due to the sound of the low-pitched vocal cords output based on the vibration of the vibrating member 100 driven by the third vibrating device.

[0300] Figure 9 This is a rear perspective view illustrating a support portion and a cover member according to another exemplary embodiment of the present disclosure. Figure 9 Examples are shown by modifying Figure 8 An exemplary embodiment implemented using the first support portion and the second support portion shown in the figure.

[0301] Reference Figure 6 and Figure 9 According to another exemplary embodiment of the present disclosure, the support portion 300 may include a first support portion 310, a second support portion 320 and a third support portion 330 respectively disposed in a first region 100A1, a second region 100A2 and a third region 100A3 of the rear portion 131 of the cover member 130 or the vibration member 100, and each support portion includes a bent portion 315.

[0302] One or more of the first support portion 310, the second support portion 320, and the third support portion 330 may have different dimensions. For example, each of the first support portion 310 and the second support portion 320 may be configured to have a smaller dimension than the third support portion 330.

[0303] Each of the first and second vibrating devices respectively disposed at the first support portion 310 and the second support portion 320 may have a relatively smaller size than the third vibrating device disposed at the third support portion 330. Therefore, each of the first and second vibrating devices may be configured to produce a high-pitched vocal cord sound.

[0304] Figure 10 A vibration generator according to another exemplary embodiment of the present disclosure is illustrated. Figure 11 It is along Figure 10 Example of a cross-sectional view taken from line II-II' in the diagram. Figure 12 This is an example Figure 11 An example of a rear perspective view of the vibrating portion shown. Figures 10 to 12 The above reference is an example. Figures 1 to 10 Another exemplary implementation of the described vibration generator.

[0305] Reference Figures 10 to 12 The vibration generator 510 according to the first exemplary embodiment of this disclosure may be referred to as a flexible vibration structure, flexible vibrator, flexible vibration generating device, flexible vibration generator, flexible speaker, flexible sound device, flexible sound generating device, flexible sound generator, flexible actuator, flexible loudspeaker, flexible piezoelectric loudspeaker, membrane actuator, membrane piezoelectric composite actuator, membrane loudspeaker, membrane piezoelectric loudspeaker or membrane piezoelectric composite loudspeaker, etc., but the embodiments of this disclosure are not limited thereto.

[0306] The vibration generator 510 according to a first exemplary embodiment of the present disclosure may include a vibration portion 511. The vibration portion 511 may include a vibration layer 511a, a first electrode layer 511b, and a second electrode layer 511c.

[0307] The vibrating layer 511a may include a piezoelectric material (or an electroactive material) that exhibits a piezoelectric effect. For example, a piezoelectric material may possess the property that, when pressure or torsion (or bending) is applied to the crystal structure by an external force, a potential difference arises due to dielectric polarization caused by changes in the relative positions of positive (+) ions and negative (-) ions, and vibration is generated by an electric field based on a reverse voltage applied thereto. The vibrating layer 511a may be referred to as a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a piezoelectric material portion, an electroactive portion, a piezoelectric structure, a piezoelectric composite layer, a piezoelectric compound, or a piezoelectric ceramic composite, etc., but embodiments of this disclosure are not limited thereto. The vibrating layer 511a may be formed of a transparent, translucent, or opaque piezoelectric material. The vibrating layer 511a may be transparent, translucent, or opaque.

[0308] The vibrating layer 511a according to an exemplary embodiment of the present disclosure may include a plurality of first portions 511a1 and a plurality of second portions 511a2. For example, the plurality of first portions 511a1 and the plurality of second portions 511a2 may be arranged alternately and repeatedly along a first direction X (or a second direction Y). For example, the first direction X may be the transverse direction of the vibrating layer 511a and the second direction Y may be the longitudinal direction of the vibrating layer 511a, but the embodiments of the present disclosure are not limited thereto; the first direction X may be the longitudinal direction of the vibrating layer 511a and the second direction Y may be the transverse direction of the vibrating layer 511a.

[0309] Each of the plurality of first portions 511a1 can be configured as an inorganic material portion. The inorganic material portion may include a piezoelectric material having a piezoelectric effect, a composite piezoelectric material, or an electroactive material.

[0310] Each of the plurality of first portions 511a1 can be configured as a ceramic-based material for generating relatively high vibrations, or can be configured as a piezoelectric ceramic having a perovskite-based 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, while "O" can be an anion. For example, each of the plurality of first portions 511a1 can contain 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.

[0311] The vibrating layer 511a or the first portion 511a1 according to another exemplary embodiment of the present disclosure may include one or more of lead (Pb), zirconium (Zr), titanium (Ti), zinc (Zn), nickel (Ni) and niobium (Nb), but the embodiments of the present disclosure are not limited thereto.

[0312] 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 nickel zirconate lead niobate (PZNN) based material, including lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb), but 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, each of which is lead-free (Pb), but embodiments of this disclosure are not limited thereto.

[0313] Each of the plurality of first portions 511a1 according to an exemplary embodiment of the present 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 the second direction Y (or the first direction X). Each of the plurality of second portions 511a2 may have a second width W2 parallel to the first direction X (or the second direction Y) and may have a length parallel to the second direction Y (or the 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 line shapes or strip shapes having the same or substantially the same size or different sizes. Thus, the vibrating layer 511a may include a 2-2 composite structure with piezoelectric properties having 2-2 vibration modes, and thus may have a resonant frequency of 20 kHz or less, but embodiments of the present 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, etc.

[0314] In the vibrating layer 511a, each of the plurality of first portions 511a1 and the plurality of second portions 511a2 may be arranged parallel to each other (or arranged in the same plane (or the same layer). Each of the plurality of second portions 511a2 may be configured to fill the gap between two adjacent first portions of the plurality of first portions 511a1, and may be connected or attached to the adjacent second portion 511a2. Therefore, the vibrating layer 511a may extend to a desired size or length based on the lateral connection (or connection) between the first portions 511a1 and the second portions 511a2.

[0315] In the vibrating layer 511a, the width (or dimension) W2 of each of the plurality of second portions 511a2 may gradually decrease in the direction from the central portion of the vibrating layer 511a or the vibration generator 510 to the two outer peripheries (or the two ends or the two portions).

[0316] According to an exemplary embodiment of this disclosure, the second portion 511a2 having the largest width W2 among the plurality of second portions 511a2 can be located at the portion where the highest stress can 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 having the smallest width W2 among the plurality of second portions 511a2 can 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 having the largest width W2 among the plurality of second portions 511a2 can be disposed at the central portion of the vibrating layer 511a, and the second portion 511a2 having the smallest width W2 among the plurality of second portions 511a2 can be disposed at each of the two outer peripheries of the vibrating layer 511a. Therefore, when the vibrating layer 511a or the vibration generator 510 vibrates in the vertical direction Z, the interference of sound waves or the overlap of resonant frequencies (each occurring in the portion with the highest stress concentration) can be reduced or minimized. Therefore, the drop in sound pressure level 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.

[0317] In the vibrating layer 511a, each of the plurality of first portions 511a1 may have a different size (or width). For example, the size (or width) of each of the plurality of first portions 511a1 may gradually decrease or increase in the direction from the central portion of the vibrating layer 511a or the vibration generator 510 to the two outer peripheries (or the two ends or the two portions). For example, in the vibrating layer 511a, the sound pressure level characteristics of the sound may be enhanced, and the sound reproduction frequency band may be increased based on the various inherent vibration frequencies according to the vibration of each of the plurality of first portions 511a1 with different sizes.

[0318] 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 lattice of each first portion 511a1 can be increased by the corresponding second portion 511a2, and thus, the vibrational characteristics can be increased, and the piezoelectric properties and flexibility can be fixed. For example, the second portions 511a2 may comprise one or more of epoxy-based polymers, acrylic-based polymers, and silicone-based polymers, but embodiments of this disclosure are not limited thereto.

[0319] 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 and thus can absorb impacts applied to the inorganic material portions (or the first portion), can release stress concentrated on the inorganic material portions to enhance the overall durability of the vibration layer 511a or vibration generator 510, and can provide 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 that matches the shape of the curved portion of the support portion. 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 portion.

[0320] The organic material portion disposed at the second part 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 part 511a1. For example, the second part 511a2 may be referred to as an adhesive portion, elastic portion, bending portion, damping portion, or flexible portion, etc., each having flexibility, but embodiments of this disclosure are not limited thereto.

[0321] Multiple first portions 511a1 and second portions 511a2 can be disposed (or connected) on the same plane, and therefore, the vibration layer 511a according to an exemplary embodiment of the present disclosure can be a single membrane type or a single thin 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 that extends through the entire vibration layer 511a. For example, the vibration layer 511a can vibrate vertically by means of the first portions 511a1 having vibrational properties, and can be bent into a curved shape by means of the flexible second portions 511a2. In addition, 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 properties 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 properties 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 exemplary 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 its desired properties, and thus, the vibrating layer 511a can be easily designed.

[0322] 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 disposed together or 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-body 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 substantially the same shape as the vibration layer 511a, but embodiments of this disclosure are not limited thereto.

[0323] 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 disposed together or connected to 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, 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-body 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 embodiments of this disclosure are not limited thereto.

For example, the vibrating layer 511a can alternately and repeatedly contract and / or expand based on the inverse piezoelectric effect of the vibration of an acoustic signal (or speech signal or drive signal) applied externally to the first electrode layer 511b and the second electrode layer 511c. For example, the vibrating layer 511a can vibrate based on the vertical and planar vibrations of the acoustic 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.

When the first power line PL1 is configured not to overlap with the second power line PL2, a short circuit between the first power line PL1 and the second power line PL2 can be prevented.

[0339] The pad component 516 may be configured 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 or a portion) of each of the first power line PL1 and the second power line PL2.

[0341] The first pad electrode can 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 can 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.

[0343] According to an exemplary embodiment of this disclosure, each of the first power line PL1, the second power line PL2, and the pad component 516 may be configured to be transparent, translucent, or opaque.

[0344] According to another exemplary embodiment of this disclosure, the pad component 516 can be electrically connected to the signal cable 517.

[0345] The signal cable 517 can be electrically connected to the pad component 516 disposed at the vibration generator 510, and can provide 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 component 516 and a second terminal electrically connected to a second pad electrode of the pad component 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.

[0346] 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 component.

For example, when the vibration generator 510 is connected or coupled to a vibrating member including various curved portions by means of a connecting member, the vibration generator 510 can be bent in a curved shape along the shape of the curved portion of the vibrating member, and despite being bent in a curved shape, the reliability against damage or breakage may not be reduced. In addition, in the vibration generator 510 according to another exemplary embodiment of the present disclosure, the vibration width (or displacement width) can be increased due to the flexible second portion 511a2 having flexibility. Therefore, the sound characteristics and / or sound pressure level characteristics generated based on the vibration of the vibrating member can be enhanced.

Each of the plurality of first portions 511a1 may include a piezoelectric material, which may be as described above.

[0360] Each of the plurality of first portions 511a1 may have a flat structure in a triangular shape. For example, each of the plurality of first portions 511a1 may have a triangular plate shape, but embodiments of this disclosure are not limited thereto. Each of the plurality of first portions 511a1 may include a piezoelectric material, said piezoelectric material being as described above. Figures 10 to 12 The first part 511a1 described is the same or substantially the same, and therefore the same reference numerals may refer to the same elements, and repeated descriptions may be omitted for brevity.

[0361] According to an exemplary embodiment of this disclosure, four adjacent first portions 511a1 of a plurality of first portions 511a1 may be adjacent to each other to form a quadrilateral (or a square shape or a quadrilateral shape). The vertices of the four adjacent first portions 511a1 forming the quadrilateral shape may be adjacent to each other in the central portion (or central part) of the quadrilateral shape.

[0362] The second portion 511a2 may be disposed between the plurality of first portions 511a1 along each of the first direction X and the second direction Y. The second portion 511a2 may be configured to surround each of the plurality of first portions 511a1, and therefore 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 disposed) on the same plane (or the same layer).

[0364] Figure 16 A vibration generator according to another exemplary embodiment of the present disclosure is illustrated, and Figure 17 It is along Figure 16 An example of a cross-sectional view taken by line III-III' shown. Figure 16 and Figure 17 Examples of references Figures 1 to 9 Another exemplary implementation of the described vibration generator.

[0365] Reference Figure 16 and Figure 17 According 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.

[0366] 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 based on the piezoelectric effect of vibration. The first vibrating portion 511-1 and the second vibrating portion 511-2 can be disposed or laid flat at a certain interval (or distance) D1. Therefore, the vibration generator 510 in which the first vibrating portion 511-1 and the second vibrating portion 511-2 are disposed 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.

[0367] 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 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 about 5 cm or more. For example, each of the first vibration portion 511-1 and the second vibration portion 511-2 may have a square shape with a size of 5 cm × 5 cm or more, but the embodiments of the present disclosure are not limited thereto.

[0368] 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, and thus 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.

[0369] 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) D1, and thus can be implemented as a single vibrating device (or a single vibrating device) that is driven as a complete single entity rather than being driven independently. According to an exemplary embodiment of this disclosure, with respect to the first direction X, 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 can be 0.1 mm or greater and less than 3 cm, but embodiments of this disclosure are not limited thereto.

[0370] According to an exemplary embodiment of this disclosure, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 can be configured or tiled to have a first separation distance (or interval) D1 of 0.1 mm or greater and less than 3 cm, and thus can be driven as a vibrating device to increase the sound reproduction band and sound pressure level characteristics of the sound generated based on the single-body vibration 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 can be configured with a first separation distance (or interval) D1 of 0.1 mm or greater and less than 5 mm to increase the sound reproduction band of the sound generated based on the single-body vibration of the first vibrating portion 511-1 and the second vibrating portion 511-2, and to increase the sound of the low-pitched vocal band (e.g., sound pressure level characteristics of 500 Hz or less).

[0371] According to an exemplary embodiment of this disclosure, when the first vibration portion 511-1 and the second vibration portion 511-2 are set to a first separation distance (or interval) D1 of less than 0.1 mm or do not have a first separation distance 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 breakage caused by physical contact between them when each of the first vibration portion 511-1 and the second vibration portion 511-2 vibrates.

[0372] According to an exemplary embodiment of this disclosure, when the first vibrating portion 511-1 and the second vibrating portion 511-2 are set to a first separation distance 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 sound reproduction band and sound pressure level characteristics 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 set to a first separation distance D1 of 3 cm or greater, the sound characteristics and sound pressure level characteristics of the low-pitched vocal band (e.g., 500 Hz or lower) can be reduced.

[0373] According to an exemplary embodiment of this disclosure, when the first vibration portion 511-1 and the second vibration portion 511-2 are set to a first separation distance D1 of 5 mm, each of the first vibration portion 511-1 and the second vibration portion 511-2 may not be driven entirely as a vibration device, and thus, each may reduce the sound characteristics and sound pressure level characteristics of the low-pitched vocal band (e.g., 200 Hz or less).

[0374] According to another exemplary embodiment of this disclosure, when the first vibrating portion 511-1 and the second vibrating portion 511-2 are set to a first separation distance D1 of 1 mm, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 can be driven as a vibration device, and thus, the sound reproduction band 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 set to a first separation distance D1 of 1 mm, 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 single-body vibration of the first vibrating portion 511-1 and the second vibrating portion 511-2, and thus, the sound characteristics and sound pressure level characteristics can each increase the sound reproduction band in the low-pitched vocal band generated based on the large-area vibration of the vibration generator 510.

[0375] Therefore, in order to achieve single-body vibration (or a single vibration device) of the first vibrating part 511-1 and the second vibrating part 511-2, the first 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 single-body vibration (or a single vibration device) of the first vibrating part 511-1 and the second vibrating part 511-2 and to increase the sound pressure level characteristics of the low-pitched vocal cords, the first 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.

[0376] 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.

[0377] The vibration layer 511a of each of the first vibration portion 511-1 and the second vibration portion 511-2 may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the vibration layer 511a of each of the first vibration portion 511-1 and the second vibration portion 511-2 may be configured to be in accordance with the above reference. Figures 12 to 15 Any of the described vibration layers 511a are substantially the same, and therefore the same reference numerals may refer to the same elements, and repeated descriptions may be omitted for brevity.

[0378] 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-mentioned reference. Figures 12 to 15 The described vibration portion 511 may be any one of the vibration portions 511, or may include different vibration portions 511.

[0379] 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 11 and Figure 12 The first electrode layer 511b described is substantially the same; therefore, the same reference numerals can denote the same elements, and repeated descriptions can be omitted for brevity.

[0380] 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 11 and Figure 12 The second electrode layer 511c described is substantially the same; therefore, the same reference numerals can denote the same elements, and for the sake of brevity, repeated descriptions can be omitted.

[0381] The vibration generator 510 according to another exemplary embodiment of the present disclosure may further include a first cover member 512 and a second cover member 513.

[0382] The first cover member 512 can be disposed on the first surface of the vibration generator 510. For example, the first cover member 512 can 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, and therefore, the first cover member 512 can be commonly connected to, or commonly 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 can 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.

[0383] The second cover member 513 can be disposed on the second surface of the vibration generator 510. For example, the second cover member 513 can 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, and therefore, the second cover member 513 can be commonly connected to the second surface of each of the first vibration portion 511-1 and the second vibration portion 511-2, or can commonly 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 can 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.

[0384] The first cover member 512 and the second cover member 513 according to exemplary embodiments of the present disclosure may each comprise one or more materials such as plastic, fiber, leather, wood, cloth, rubber, 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.

[0385] According to an exemplary embodiment of the present disclosure, the first cover member 512 may be disposed on the first surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2 via a first adhesive layer 514. For example, the first cover member 512 may be directly disposed on the first surface of each of the first vibrating portion 511-1 and the second vibrating portion 511-2 via a film lamination process using the first adhesive layer 514. Therefore, each of the first vibrating portion 511-1 and the second vibrating portion 511-2 may be integrated (or disposed) with the first cover member 512 or laid flat with a first separation distance D1.

[0386] According to an exemplary embodiment of the present disclosure, the second cover member 513 can be disposed on the second surface of each of the first vibration portion 511-1 and the second vibration 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 vibration portion 511-1 and the second vibration portion 511-2 via a film lamination process using the second adhesive layer 515. Therefore, each of the first vibration portion 511-1 and the second vibration portion 511-2 can be integrated (or disposed) with or laid flat with the second cover member 513 having a first separation distance 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.

[0387] The first adhesive layer 514 may be disposed between the first vibrating portion 511-1 and the second vibrating portion 511-2, and 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 surface of the first cover member 512 facing 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 filling 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.

[0388] The second adhesive layer 515 may be disposed between the first vibrating portion 511-1 and the second vibrating portion 511-2, and disposed on 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 surface 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 filling 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.

[0389] 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 space between the first adhesive layer 514 and the second adhesive layer 515.

[0390] Each of the first adhesive layer 514 and the second adhesive layer 515 according to exemplary embodiments of the present disclosure may comprise an electrically insulating material that is adhesive and capable of compression and decompression. For example, each of the first adhesive layer 514 and the second adhesive layer 515 may comprise 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.

[0391] 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 component 518 electrically connected to the first power line PL1 and the second power line PL2.

[0392] 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, electrically 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.

[0393] 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 a second direction Y. For example, the first upper power line PL11 may be connected or electrically 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 and directly connected to the first electrode layer 511b of the second vibration portion 511-2.

[0394] The second power line PL2 can be disposed on the front surface of the second surface of the second cover member 513 facing each of the first vibration portion 511-1 and the second vibration portion 511-2. The second power line PL2 can be connected or electrically 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.

[0395] 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.

[0396] The pad component 518 may be configured 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.

[0397] The pad component 518 according to an exemplary embodiment of the present disclosure may include a first pad electrode electrically connected to one end (or a portion) of a first power line PL1 and a second pad electrode electrically connected to one end (or a portion) of a second power line PL2.

[0398] 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.

[0399] The vibration generator 510 according to another exemplary embodiment of the present disclosure may also include a signal cable 519.

[0400] The signal cable 519 can be electrically connected to the pad component 518 disposed at the vibration generator 510, and can provide 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 component 518 and a second terminal electrically connected to a second pad electrode of the pad component 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.

[0401] 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 either a positive (+) vibration drive signal or a negative (-) vibration drive signal, and the second vibration drive signal can also be either a positive (+) vibration drive signal or a negative (-) vibration drive signal. For example, the first vibration drive signal can be provided 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 component 518, and the first power line PL1. The second vibration drive signal can be provided 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 component 518, and the second power line PL2.

[0402] The vibration generator 510 according to another exemplary embodiment of this disclosure can be configured as a thin-film type (or may be a thin-film) to correspond with the above-mentioned... Figures 10 to 15 The vibration generator 510 described is similar in manner, and therefore can be bent in 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. Additionally, the vibration generator 510 according to another exemplary embodiment of this disclosure may include a first vibrating portion 511-1 and a second vibrating portion 511-2, the first vibrating portion 511-1 and the second vibrating portion 511-2 being arranged (or tiled) with a first separation distance D1 so as to be configured in a single vibrating body without being driven independently, and therefore can be driven as a large-area vibrating body based on the single-body vibration of the first vibrating portion 511-1 and the second vibrating portion 511-2.

[0403] Figure 18 A vibration generator according to another exemplary embodiment of the present disclosure is illustrated. Figure 18 Examples are shown in Figure 16 and Figure 17 An exemplary embodiment of the vibration generator shown provides four vibrating parts. Therefore, in the following description, the same or similar elements other than the four vibrating parts and related components may be referred to by the same reference numerals.

[0404] This indicates that repeated descriptions of these terms may be omitted or will be given briefly. Figure 17 The example shown is along Figure 18

[0405] An example of a cross-sectional surface cut by line III-III' shown.

[0406] Reference Figure 17 and Figure 18 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.

[0407] Multiple vibrating portions 511-1 to 511-4 may be electrically disconnected and 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 may be arranged in an i×j configuration or laid flat on the same plane, and thus, the vibration generator 510 can be implemented to have a large area based on the tiling of multiple vibrating portions 511-1 to 511-4 having relatively small dimensions. For example, i may be the number of vibrating portions arranged along the first direction X, and may be a natural number of 2 or greater, and j may be the number of vibrating portions arranged along the second direction Y, and may be a natural number of 2 or greater, which may be the same as or different from i. For example, the multiple vibrating portions 511-1 to 511-4 may be arranged in a 2×2 configuration or laid flat, 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.

[0408] 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.

[0409] The first vibrating portions 511-1 to the fourth vibrating portions 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 jointly connected to the first vibrating portions 511-1 to the fourth vibrating portions 511-4, or can jointly support the first vibrating portions 511-1 to the fourth vibrating portions 511-4, and thus the first vibrating portions 511-1 to the fourth vibrating portions 511-4 can be driven as a vibrating device (or a single vibrating device). For example, the first vibrating portions 511-1 to the fourth vibrating portions 511-4 can be laid flat by the cover members 512 and 513 at a certain interval D1 and D2, and thus can be driven as a vibrating device (or a single vibrating device).

[0410] According to exemplary embodiments of this disclosure, as referred to above... Figure 16 and Figure 17 In order to achieve single-body 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 D1 and D2 of 0.1 mm or greater and less than 3 cm, or can be set (or laid flat) at intervals D1 and D2 of 0.1 mm or greater and less than 5 mm along each of the first direction X and the second direction Y.

[0411] 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.

[0412] The vibration layer 511a of each of the first vibration portions 511-1 to the fourth vibration portions 511-4 may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the vibration layer 511a of each of the first vibration portions 511-1 to the fourth vibration portions 511-4 may be configured to be similar to the above-referenced Figures 12 to 15 Any of the described vibration layers 511a are substantially the same, and therefore the same reference numerals may refer to the same elements, and repeated descriptions may be omitted for brevity.

[0413] 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-mentioned reference. Figures 12 to 15 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 those referenced above. Figures 12 to 15 The different vibration layers 511a are described.

[0414] The first electrode layer 511b can be disposed on 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. Figure 11 and Figure 12 The first electrode layer 511b described is substantially the same, and therefore the same reference numerals can denote the same elements, and for the sake of brevity, their repeated descriptions can be omitted.

[0415] The second electrode layer 511c can be disposed on the second surface of the corresponding 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 11 and Figure 12 The second electrode layer 511c described is substantially the same; therefore, the same reference numerals can denote the same elements, and for the sake of brevity, repeated descriptions can be omitted.

[0416] According to an exemplary embodiment of this disclosure, the first adhesive layer 514 and the second adhesive layer 515 may be connected or joined to each other between the first vibrating portions 511-1 to the fourth vibrating portions 511-4. 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 space between the first adhesive layer 514 and the second adhesive layer 515.

[0417] The vibration generator 510 according to another exemplary embodiment of the present disclosure may further include a first power line PL1, a second power line PL2, and a pad component 518.

[0418] 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 connected to the structure described above. Figure 16 and Figure 17 Each of the first power line PL1 and the second power line PL2 described is substantially the same; therefore, in the following description, only a brief description will be given of 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.

[0419] 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 a 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. The second upper power line PL12 may be electrically connected to a first electrode layer 511b of each of the second vibration portion 511-2 and the fourth vibration portion 511-4 disposed in a second row parallel to the second direction Y in the first vibration portion 511-1 to the fourth vibration portion 511-4.

[0420] 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 the second electrode layer 511c 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 among the first vibration portion 511-1 to the fourth vibration portion 511-4. The second lower power line PL22 may be electrically connected to the second electrode layer 511c of each of the second vibration portion 511-2 and the fourth vibration portion 511-4 disposed in a second row parallel to the second direction Y among the first vibration portion 511-1 to the fourth vibration portion 511-4.

[0421] The pad component 518 may be disposed at an edge portion (or a peripheral portion) of one of the first cover member 512 and the second cover member 513 for electrical connection to one side (or an end or a portion) of each of the first power line PL1 and the second power line PL2. The pad component 518 may be connected to... Figure 16 and Figure 17 The pad components 518 shown are substantially the same, and therefore the same reference numerals may denote the same components, and repeated descriptions may be omitted for brevity.

[0422] According to another exemplary embodiment of the present disclosure, the vibration generator 510 may have the same characteristics as described above. Figure 16 and Figure 17 The vibration generator 510 described has the same effect, and therefore, for the sake of brevity, its repeated description can be omitted.

[0423] Figure 19 A vibration generator according to another exemplary embodiment of the present disclosure is illustrated. Figure 20 It is along Figure 19 Example of a cross-sectional view taken by line IV-IV' in the diagram. Figure 19 and Figure 20 Examples of references Figures 1 to 10 Another exemplary implementation of the described vibration generator.

[0424] Reference Figure 19 and Figure 20 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 middle member) 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.

[0425] Multiple vibration generating portions (or a first vibration generating portion and a second vibration generating portion) 510A and 510B may overlap or be stacked to shift (or drive or vibrate) 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 portion, 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.

[0426] Multiple vibration generating parts (or the first vibration generating part and the second vibration generating part) 510A and 510B can be referenced above. Figures 10 to 18 Any of the vibration generators 510 described herein, and therefore, for the sake of brevity, repeated descriptions of them may be omitted.

[0427] Multiple vibration generating portions 510A and 510B can overlap or stack based on the polarization direction of the vibration layer 511a to shift (or drive or vibrate) in the same direction. 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 to each other, the second vibration generating portion 510B can be disposed on the front or rear surface of the first vibration generating portion 510A, as a vertically inverted type.

[0428] An intermediate member 510m can be disposed or inserted between a plurality of 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 having a relatively strong adhesion or bonding force with respect to each of the plurality of vertically overlapping vibration generators 210 and 230.

[0429] The intermediate component 510m according to an exemplary embodiment of this disclosure may include foam pads, single-sided tape, double-sided tape, single-sided foam pads, double-sided foam pads, single-sided foam tape, double-sided foam tape, or adhesives, but the embodiments of this disclosure are not limited thereto. For example, the adhesive layer of the intermediate component 510m may include epoxy resin-based, acrylic-based, silicone-based, or urethane-based materials, but the embodiments of this disclosure are not limited thereto. The adhesive layer of the intermediate component 510m may include urethane-based materials, which have relatively ductile properties compared to acrylic and urethane materials. Therefore, in the vibration generator 510 according to another exemplary 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.

[0430] According to another exemplary embodiment of this disclosure, the intermediate component 510m may include one or more of thermosetting adhesives, photocurable adhesives, and thermal bonding adhesives. For example, the intermediate component 510m may include a thermal bonding adhesive. The thermal bonding adhesive may be of a thermoactive type or a thermosetting type. For example, the intermediate component 510m including a thermal bonding adhesive may attach or join two adjacent vibration generating portions 510A and 510B by heat and pressure. For example, the intermediate component 510m including a thermal bonding adhesive may minimize or reduce the vibration loss of the vibration generator 510.

[0431] Multiple vibration-generating parts 510A and 510B can be integrated into a single structure (or element or component) by using a lamination process with intermediate member 510m. For example, multiple vibration-generating parts 510A and 510B can be integrated into a single structure by using a lamination process with rollers.

[0432] Figures 21A to 21D This is an example Figure 19 and Figure 20 An example perspective view of a stacked structure between multiple vibration-generating layers, as shown.

[0433] Reference Figure 19 and Figure 21A 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 a plurality of second portions 511a2 disposed between the plurality of first portions 511a1. The vibration layer 511a may be in conjunction with the above reference. Figure 11 and Figure 12 The vibration layer 511a described is essentially the same, therefore, its repeated description can be omitted for brevity.

[0434] 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 located at the virtual extension line VR. 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 located at the virtual extension line VR. Therefore, the first portions 511a1 of the multiple vibration generating portions 510A and 510B can substantially overlap or stack each other 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 portions 510A and 510B, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated by the vibration of the vibration member.

Therefore, the first portions 511a1 of the multiple vibration generating portions 510A and 510B can substantially overlap or stack each other 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 portions 510A and 510B, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords generated by the vibration of the vibration member.

[0451] According to an exemplary embodiment of this disclosure, each of the first to nth support portions 310, 320, and 330 may be disposed on the rear surface of the vibrating member 600 or at the rear portion 631 of the cover member 630 to have a predetermined curvature. For example, the curved portion 315 of each of the first support portion 310, the second support portion 320, and the third support portion 330 may have a curved shape having a curvature (or a single curvature). For example, the curved portion 315 of each of the first support portion 310, the second support portion 320, and the third support portion 330 may have a curved structure having a curvature (or a single curvature) without an inflection point.

[0452] According to another exemplary embodiment of this disclosure, one or more of the curved portions 315 of each of the first to nth support portions 310, 320 and 330 may have different dimensions.

[0453] The device 3 according to the third exemplary embodiment of the present disclosure may further include a gap space GS, which is disposed between the rear surface of the vibrating member 600 or the rear portion 631 of the cover member 630 and the first to the nth vibrating devices 500 based on the support portion 300.

[0454] The gap space GS can be disposed between the rear portion 631 of the cover member 630 and the first to nth vibrating devices 500, based on the support portion 300. The gap space GS can include a space for generating sound or sound pressure level based on the vibration of each of the first to nth vibrating devices 500, a space for smoothly executing the vibration of each of the first to nth vibrating devices 500, or a space for sound waves generated based on the vibration of each of the first to nth vibrating devices 500 to propagate to the vibrating member 600.

[0456] According to another exemplary embodiment of this disclosure, each of the first to nth vibration devices 500 may be coupled to or attached to the curved portion 315 of the support portion 300, and thus may have prestress or receive prestress based on the curved portion 315. For example, each of the first to nth vibration devices 500 may receive tensile stress or tensile stress including that based on the curvature of the curved portion 315 of the support portion 300. For example, the curved portion 315 of the support portion 300 may be configured to apply tensile stress only to each of the first to nth vibration devices 500 in order to enhance the vibration characteristics of each of the first to nth vibration devices 500. Thus, each of the first to nth vibration devices 500 may vibrate in a state where it receives prestress (or pre-tension stress) or is bent in a curved shape, and thus, the second moment of inertia may be increased or the vibration direction may be implemented in a single direction.

[0457] Each of the first to nth vibration devices 500 may include the above reference. Figure 5 The described vibration equipment and the above reference Figures 10 to 21D The vibration generator is described. Therefore, the above refers to...

[0458] Each of the first to nth vibration devices 500 can be configured to produce the sound of vocal cords with the same pitch, or can be configured to produce the sound of vocal cords with different pitches. For example, the device 3 according to the third exemplary embodiment of the present disclosure may include the first to nth vibration devices 500 respectively disposed at the curved portions 315 of each of the first to nth support portions 310, 320 and 330, and each of the first to nth vibration devices 500 can be configured to produce the sound of vocal cords with the same pitch, or can be configured to produce the sound of vocal cords with different pitches.

[0459] One or more of the first to nth vibration devices 500 can be configured to produce sounds from different pitch vocal cords or low-pitched vocal cords. Therefore, the device 3 according to the third exemplary embodiment of this disclosure can output sound, for example, stereo or high-definition stereo, and can have multi-channel sound output characteristics due to the sound generated or output based on the region-based vibration of the vibrating member 600 according to the vibration of each of the first to nth vibration devices 500.

[0460] As described above, the device 3 according to the third exemplary embodiment of this disclosure may include a first to an nth vibrating device 500, which vibrate in a state of receiving prestress (or pre-tension stress) or bending in a curved shape. Therefore, the second moment of inertia of the first to nth vibrating devices 500 may be increased, or the vibration direction of the first to nth vibrating devices 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 vibrating member 600, which vibrates based on the vibration of the first to nth vibrating devices 500. The device 3 according to the third exemplary embodiment of this disclosure can cause the vibrating member 600 to vibrate to output sound based on the vibration of each of the first to nth vibrating devices 500, and thus can output, for example, stereo or high-definition stereo sound, wherein the acoustic characteristics and / or sound pressure level characteristics are enhanced, and it may have multi-channel sound output characteristics.

In another example, n may be a natural number of 1, so that one hole 637 may overlap with one vibrating device 500.

[0463] Each of the first to nth holes 637 can be formed at the cover member 630, overlapping with a corresponding one of the first to nth vibration devices 500. For example, each of the first to nth holes 637 can be formed to pass through the rear portion 631 of the cover member 630 along a third direction Z, overlapping with a corresponding one of the first to nth vibration devices 500.

[0465] Similar to device 3 according to the third exemplary embodiment of this disclosure, device 4 according to the fourth exemplary embodiment of this disclosure can vibrate in a state where the vibrating device 500 receives prestress (or pre-tension stress) or is bent in 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 made unidirectional, thereby enhancing 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. Additionally, device 4 according to the fourth exemplary embodiment of this disclosure may include one or more of a first to an nth hole 637 formed in the cover member 630, and therefore, the sound (or sound waves) generated based on the vibration of the vibrating device 500 can be directly transmitted to the vibrating panel 610.

Furthermore, device 6 according to the sixth exemplary embodiment of this disclosure may include one or more holes 837 formed at the base member 800 or the substrate 810, and therefore, the sound (or sound waves) generated based on the vibration of the vibrating device 500 can be directly transmitted to the vibrating member 900.
