Description

[Technical Field]

[0001] This specification relates to the apparatus. [Background technology]

[0002] The device includes separate speakers or sound equipment to provide sound. When speakers are placed within the device, the speakers occupy space, which creates constraints on the device's design and spatial placement.

[0003] The speaker applied to the device could be, for example, an actuator containing a magnet and a coil. However, when an actuator is applied to a display device, it has the disadvantage of being thick. Therefore, piezoelectric elements, which can achieve a thin profile, are attracting attention.

[0004] Piezoelectric elements have a brittle characteristic, making them easily damaged by external impacts, which leads to unreliable sound reproduction. Furthermore, when piezoelectric elements are used as speakers in flexible devices, their brittle characteristics can cause damage.

[0005] The descriptions provided in the background art should not be considered prior art simply because they refer to or relate to the background art. The discussion of prior art may include information describing one or more examples of the present art, and the description of the background art is not intended to limit the inventions of this specification. [Overview of the project] [Problems that the invention aims to solve]

[0006] Therefore, the inventors of this specification recognized the problems and shortcomings of the background technology, as well as the problems mentioned above, and conducted numerous studies and experiments to realize a vibration device that can improve the sound quality and sound pressure characteristics of acoustics. Through these studies and experiments, they invented a device including a new vibration device that can improve the sound quality and sound pressure characteristics of acoustics.

[0007] The problem to be solved by the embodiments of this specification is to provide an apparatus including a vibration device that can generate vibration or sound by vibrating a vibrating member, and that can improve the acoustic characteristics and / or sound pressure characteristics.

[0008] Additional features, advantages, and examples of the invention as described herein are partially described in the following description, partially clarified herein, and can be learned from the examples of the concept of the invention provided herein. Other features, advantages, and examples of the concept of the invention are realized, achieved, and can be achieved by the description, claims, as well as the accompanying drawings, which are provided herein or can be derived therefrom. [Means for solving the problem]

[0009] Apparatuses according to one or more embodiments of this specification include a vibrating member and a vibrating device configured to vibrate the vibrating member, wherein the vibrating device is composed of a first vibrating section and a second vibrating section different from the first vibrating section.

[0010] Apparatuses according to one or more embodiments of this specification include a vibrating member having first to n (n is a natural number of 2 or more) regions, and a vibration generating device located on the back of the vibrating member and causing the vibrating member to vibrate, wherein the vibration generating device includes first to n vibrating devices connected to the first to n regions of the vibrating member, each of the first to n vibrating devices consisting of a first vibrating part and a second vibrating part different from the first vibrating part, and the sound output from one or more of the first to n regions has a different frequency range than the sound output from one or more other of the first to n regions.

[0011] An apparatus according to one or more embodiments of this specification includes an exterior material covering a main structure, an interior material covering the main structure and one or more of the exterior materials, and one or more vibration generating devices located between the main structure and the exterior material, between the main structure and the interior material, in the exterior material, and in one or more of the interior materials, wherein the one or more vibration generating devices consist of a first vibrating section and a second vibrating section different from the first vibrating section, the vibrating members of the one or more vibration generating devices are one or more of the exterior material and the interior material, and one or more of the exterior material and the interior material emit sound through vibration of the one or more vibration generating devices. [Effects of the Invention]

[0012] The apparatus according to the embodiments of this specification can generate sound such that the direction of sound propagation is in front of the display panel or vibrating member, by configuring a vibration device that vibrates the display panel or vibrating member.

[0013] Since the apparatus according to the embodiments of this specification is composed of a vibrating device including a single crystal and a polycrystal, by complementing the acoustic characteristics and / or sound pressure characteristics in the low-frequency range with the single crystal, it is possible to provide an apparatus including a vibrating device that has uniform acoustic characteristics and / or sound pressure characteristics in the frequency range.

The relative sizes and depictions of these elements may be exaggerated for clarity, explanation, and convenience. [Modes for carrying out the invention]

[0019] Examples of the embodiments described herein are given in detail, and such examples can be illustrated in the accompanying drawings. Where a specific description of a well-known function or configuration would unnecessarily obscure the gist of this specification, such description may be omitted for the sake of brevity. The described steps and / or operations are illustrative, but the order of the steps and / or operations is not limited to those described herein and can be changed except for steps and / or operations that do not necessarily occur in a particular order.

[0020] Unless otherwise specified, the same reference numeral can refer to components that are generally similar, even if they are illustrated in different drawings. In one or more embodiments, identical components (or components with the same name) in different drawings may have the same or substantially the same function and characteristics unless otherwise specified. The names of the components used in the following description are chosen for convenience and may differ from those of the actual product.

[0021] The advantages and features of this specification and the methods for achieving them will become clear from the various examples described below in detail with reference to the accompanying drawings. However, this specification is not limited to the embodiments disclosed below, and can be realized in a variety of different forms, and the embodiments described herein are provided only to complete the disclosure of this specification and to fully inform those who have ordinary skill in the art to which the technical concept of this specification pertains.

[0022] The shapes, sizes, areas, ratios, angles, and quantities disclosed in the drawings illustrating one embodiment of this specification are illustrative only, and this specification is not limited to those depicted.

[0023] Wherever the terms “includes,” “have,” “consist of,” “form,” etc., are used herein, other parts may be added unless “only” or “solely” is used. The terms used herein are used solely to describe specific embodiments and are not intended to limit the scope of this specification. The terms used herein are used solely to describe exemplary embodiments and are not intended to limit the scope of this specification. Terms expressing components in the singular include plural forms unless otherwise explicitly stated. “Examples” may be illustrative examples. Any implementation described in an “Example” or “Example” herein is not necessarily construed as being preferred or advantageous over other implementations.

[0024] In one or more embodiments, components, features, or corresponding information (e.g., levels, ranges, dimensions, sizes, etc.) may be interpreted as including errors or tolerances, even if no explicit description of these errors or tolerances is provided. Errors or tolerances may arise from a variety of factors (e.g., process factors, internal or external impacts, noise, etc.).

[0025] When describing a spatial relationship, if the spatial relationship between two parts is described using words such as "on" or "above" or "over," "on top," "under" or "below" or "beneath," "near," "adjacent to," "beside," or "next to," then one or more other parts may be placed between the two parts unless "just," "immediately," "closely," or "directly" is used. For example, if a structure is described as being located "on or above or over," "at the top," "under or below," "below or beneath," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures are in contact with each other or where a third structure is positioned between them.

[0027] The terms "first," "second," etc., are used to describe various components, but these components are not limited to these terms. These terms are used solely to distinguish one component from another. Therefore, the first component mentioned below may also be the second component within the technical concept of this specification. Furthermore, the first element, the second element, etc., may be arbitrarily named at the convenience of those skilled in the art without departing from the scope of this specification. While terms such as "first," "second," etc., may be used to distinguish components from one another, the function or structure of a component is not limited by the preceding ordinal number or the name of the component.

[0028] In describing the components of this specification, terms such as 1st, 2nd, A, B, (a), (b), etc., may be used. Such terms are used to distinguish a component from other components and are not used to define its nature, basis, order, or number.

[0029] Where it is stated that a component or layer "connects," "joins," or "links" to another component, it should be understood that the component may directly connect to or be able to connect to the other component, but other components or layers may also be "disposed" or "interpoded" between each component that is indirectly connected or can be connected unless otherwise explicitly stated.

[0030] Where a component or layer is described as "in contact" or "superimposed" on another component or layer, it should be understood that the component may be in direct contact with or superimposed on the other component or layer, but that one or more other components or layers may also be "disposed" or "interpoded" between each component or layer that may be indirectly in contact with or superimposed on, unless otherwise explicitly stated.

[0031] Terms such as “line” or “direction” should not be interpreted solely as geometric relationships in which each line or direction is parallel or perpendicular to one another, but may mean lines or directions that have a broader directionality within the range in which the components herein can function.

[0032] The term "at least one" should be understood to include all possible combinations of one or more related items. For example, "at least one of item 1, item 2, and item 3" could mean any combination of item 1, item 2, and item 3, not just combinations of items 1 or 2 or more of item 1, item 2, or item 3.

[0033] The expressions "first component," "second component" and "and / or" "third component" should be understood as one of the first, second, and third components, or any combination or all of the first, second, and third components. For example, A, B and / or C can be considered as A only, B only, C only, any or any combination of A, B, and C, or all of A, B, and C. Furthermore, the expression "component A / component B" should be understood as component A and / or component B.

[0034] In one or more embodiments, the terms “between” and “inside” may be used interchangeably for convenience unless otherwise specified. For example, the expression “between multiple components” may also be understood as “inside multiple components.” In other embodiments, the expression “inside multiple components” may also be understood as “between multiple components.” In one or more embodiments, the number of components may be two. In one or more embodiments, the number of components may be more than two.

[0035] In one or more embodiments, the expression "different from each other" can be understood as any one component being different from the others.

[0036] In one or more embodiments, the expressions “one or more of” and “one or more of” may be used interchangeably for convenience unless otherwise specified. For example, the expression “one or more of” may also be understood as “one or more of.” For example, the expression “one or more of” may also be understood as “one or more of.”

The sealing portion according to the embodiments herein may be formed as a multilayer structure in which organic material layers and inorganic material layers are alternately stacked, but the embodiments herein are not limited thereto. The inorganic material layer can block oxygen or moisture from penetrating the light-emitting layer of the pixel array portion. The organic material layer may be formed to be relatively thicker than the inorganic material layer so as to be able to cover foreign matter (particles) that may be generated during the manufacturing process, but the embodiments herein are not limited thereto. For example, the sealing portion may include a first inorganic film, an organic film on the first inorganic film, and a second inorganic film on the organic film. The organic film may be a foreign matter cover layer, and the embodiments herein are not limited thereto.

[0061] The pad section can supply signals from an external source to the pixel array section and / or the gate drive circuit. For example, the pad section may include a plurality of data pads connected to a plurality of data lines via a plurality of data link lines and / or a plurality of gate input pads connected to the gate drive circuit via a gate control signal line. For example, the size of the first substrate may be larger than that of the second substrate, and the embodiments herein are not limited thereto.

[0062] The gate drive circuit may be embedded (or integrated) in the second edge of the first substrate so as to be connected to multiple gate lines. For example, the gate drive circuit may be implemented in a shift register that includes transistors formed by the same process as the thin-film transistors provided in the pixel region. Gate drive circuits according to other embodiments of this specification may not be embedded in the first substrate but may be included in the panel drive circuit in the form of an integrated circuit.

[0063] The second substrate may be a lower substrate or a color filter array substrate. For example, the second substrate may include a pixel aperture pattern that includes an aperture region superimposed on a pixel region formed on the first substrate, and a color filter layer formed in the aperture region. The second substrate may be smaller in size than the first substrate, and the embodiments herein are not limited thereto. For example, the second substrate may be superimposed on the remaining portion of the first substrate excluding the first edge. The second substrate may be bonded to the remaining portion of the first substrate excluding the first edge, with a liquid crystal layer in between, using a sealant.

[0064] A liquid crystal layer may be placed between a first substrate and a second substrate. The liquid crystal layer may consist of a liquid crystal in which the alignment direction of liquid crystal molecules is changed by an electric field formed by a data voltage applied to the pixel electrode for each pixel and a common voltage applied to the common electrode.

[0065] The second polarizing member is positioned on the lower surface of the second substrate and can polarize light incident from the backlight and propagating into the liquid crystal layer. The first polarizing member is positioned on the upper surface of the first substrate and can polarize light transmitted through the first substrate and emitted to the outside.

[0066] The display panel according to the embodiment of this specification can display an image by light passing through the liquid crystal layer, by driving the liquid crystal layer with an electric field formed for each pixel by a data voltage applied to each pixel and a common voltage.

[0067] In other embodiments of this specification, the display panel may consist of a first substrate made of a color filter array substrate and a second substrate made of a thin-film transistor array substrate. For example, the display panel in other embodiments of this specification may have a shape that is inverted from the display panel in the embodiment of this specification. In this case, the pad portion of the display panel in other embodiments of this specification may be covered by a separate mechanism.

[0068] Display panels according to other embodiments of this specification may include curved shapes or bends or curved portions having a certain radius of curvature.

[0069] A display panel bend can be realized in at least one of two parallel edge portions of the display panel.

[0072] The vibration device 130 can vibrate the vibrating member 100. The vibration device 130 may be implemented on the back of the vibrating member 100 so that it can directly vibrate the vibrating member 100. For example, the vibration device 130 can provide acoustic and / or haptic feedback to the user by vibrating the vibrating member 100 at its back. For example, the vibrating member 100 can output sound through the vibration of the vibration device 130. The vibration device 130 can output sound by using the vibrating member 100 as a diaphragm. For example, the vibration device 130 can output sound to the front of the vibrating member 100 by using the vibrating member 100 as a diaphragm. For example, the vibration device 130 can generate sound such that the direction of sound propagation is to the front of the display panel or the vibrating member 100. The vibration device 130 can output sound by vibrating the vibrating member 100. For example, the vibration device 130 can output sound by directly vibrating the vibrating member 100. For example, the vibrating member 100 may be an object to be vibrated, a diaphragm, or a front member, or may include one or more of these, and the embodiments herein are not limited to these terms.

[0073] According to embodiments of this specification, the vibration device 130 can vibrate the display panel by vibrating in response to a vibration drive signal synchronized with the image displayed on the display panel, which is a vibration member 100. According to other embodiments of this specification, the vibration device 130 can vibrate the display panel by vibrating in response to a haptic feedback signal (or tactile feedback signal) synchronized with the user's touch on a touch panel (or touch sensor layer) placed on or embedded in the display panel. This allows the display panel to vibrate in response to the vibration of the vibration device 130 and provide at least one of acoustic and haptic feedback to the user (or viewer).

[0074] The vibration device 130 according to the embodiments of this specification may be realized in a size corresponding to the display area (AA) of the vibrating member 100 or the display panel. The size of the vibration device 130 may be 0.9 to 1.1 times the size of the vibrating member 100 or the display area (AA), and the embodiments of this specification are not limited thereto. For example, the size of the vibration device 130 may be the same as or smaller than the size of the vibrating member 100 or the display area (AA). For example, the size of the vibration device 130 can be the same as or approximately the same as the display area (AA) of the vibrating member 100 or the display panel, so that it can cover most of the area of ​​the vibrating member 100 or the display panel, and the vibration generated from the vibration device 130 can vibrate the entire area of ​​the vibrating member 100 or the display panel, so that the sense of sound localization is high and user satisfaction may be improved. Furthermore, since the contact area (or panel coverage) between the vibrating member 100 or display panel and the vibration device 130 increases, the vibration range of the vibrating member 100 or display panel may increase, thus improving the mid-to-low frequency sound generated by the vibration of the vibrating member 100 or display panel. Moreover, the vibration device 130 applied to large devices can vibrate the entire large (or large-area) vibrating member 100 or display panel, further improving the sense of sound localization due to the vibration of the vibrating member 100 or display panel and achieving an improved sound effect.Therefore, the vibration device 130 according to the embodiment of this specification is positioned on the back of the vibrating member 100 or display panel and can sufficiently vibrate the vibrating member 100 or display panel in the vertical (or front-to-back) direction, so that the desired sound can be output to the front of the device (or display device).

[0075] Since the vibration device 130 is implemented in film form, it can have a thinner thickness than the vibration member 100 or the display panel, so that the increase in the thickness of the device can be minimized by the placement of the vibration device 130. For example, the vibration device 130 can use the vibration member 100 or the display panel as an acoustic diaphragm. For example, the vibration device 130 can be expressed as a vibration generator, displacement device, acoustic device, acoustic generation module, acoustic generator, film actuator, film piezoelectric composite actuator, film speaker, film piezoelectric speaker, or film piezoelectric composite speaker, and is not limited to these terms. In another embodiment of this specification, the vibration device 130 may be applied to a non-display panel rather than a display panel, and may not be placed on the back of the display panel. For example, the non-display panel may be one or more of wood, plastic, glass, metal, cloth, fiber, rubber, paper, leather, automotive interior materials, building ceilings, and aircraft interior materials, and is not limited to these embodiments of this specification. In this case, the non-display panel may be applied as a diaphragm, and the vibration device 130 can vibrate the non-display panel to produce sound.

[0076] The vibration device 130 according to the embodiments herein may be positioned on the back of the vibration member 100 or the display panel so as to overlap with the vibration member 100 or the display area (AA) of the display panel. For example, the vibration device 130 may overlap with more than half of the vibration member 100 or with more than half of the display area (AA) of the display panel. According to other embodiments herein, the vibration device 130 may overlap with the entire vibration member 100 or the entire display area (AA) of the display panel.

[0077] According to other embodiments of this specification, the vibrating member 100 may further include a plate 101. For example, the plate 101 is configured to have the same size as the vibrating member 100. The plate 101 may include a metallic material or one or more single nonmetallic materials or composite nonmetallic materials from among wood, plastic, glass, cloth, fiber, rubber, paper, mirror, and leather, and the embodiments of this specification are not limited thereto.

[0078] The vibration device 130 according to the embodiments of this specification can vibrate by repeatedly contracting and expanding alternately due to the inverse piezoelectric effect when an AC voltage is applied, and such vibration can be used to vibrate the vibrating member 100 or the display panel. For example, the vibration device 130 can vibrate the display panel by vibrating in response to a voice signal synchronized with the image displayed on the display panel. In another embodiment of this specification, the vibration device 130 can vibrate the display panel by vibrating in response to a haptic feedback signal (tactile feedback signal) synchronized with the user's touch on a touch panel (or touch sensor layer) placed on or built into the display panel. As a result, the display panel can vibrate in response to the vibration of the vibration device 130 and provide the user (or viewer) with at least one of acoustic and haptic feedback.

[0079] Therefore, the apparatus 10 according to the embodiment of this specification can output the sound generated by the vibration of the vibrating member 100 or the display panel due to the vibration of the vibrating device 130 to the front of the vibrating member 100 or the display panel. Furthermore, since the apparatus 10 according to the embodiment of this specification can vibrate most of the area of ​​the vibrating member 100 (or display panel) with the film-shaped vibrating device 130, the sound pressure characteristics and sound localization of the sound generated by the vibration of the vibrating member 100 (or display panel) can be further improved.

[0080] The apparatus (10) according to the embodiments of this specification may further include a connecting member 150 (or a first connecting member) between the vibrating member 100 or the vibrating device 130.

[0081] The connecting member 150 according to the embodiments of this specification can be positioned between the rear surface (or back surface) of the vibrating member 100 and the vibrating device 130 to connect or bond the vibrating device 130 to the back surface of the vibrating member 100. For example, the vibrating device 130 can be supported or positioned on the back surface of the vibrating member 100 by being connected to or bonded to the back surface of the vibrating member 100 via the connecting member 150.

[0082] The connecting member 150 according to the embodiments of this specification may be made of a material including an adhesive layer having a relatively strong adhesion or bonding force to the back surface of the vibrating member 100 and the vibrating device 130, respectively.

For example, the adhesive layer of the connecting member 150 may include epoxy, acrylic, silicone, or urethane, and the embodiments of this specification are not limited thereto. For example, the adhesive layer of the connecting member 150 may include an acrylic-based substance (or material) among acrylic and urethane that has a relatively strong adhesive force and high hardness. This allows the vibrations of the vibrating device 130 to be effectively transmitted to the vibrating member 100.

[0083] The adhesive layer of the connecting member 150 may further contain additives such as tackifiers, wax components, or antioxidants, and the examples herein are not limited thereto. The additives can prevent the connecting member 150 from separating (or peeling off) from the vibrating member 100 due to vibration of the vibrating device 130. For example, the tackifier may be a rosin derivative, the wax component may be paraffin wax, and the antioxidant may be a phenolic antioxidant such as a thioester, and the examples herein are not limited thereto.

[0084] Other embodiments of the connecting member 150 according to this specification may further include a hollow portion provided between the vibrating member 100 and the vibrating device 130. The hollow portion of the connecting member 150 can provide an air gap between the vibrating member 100 and the vibrating device 130. The air gap minimizes vibration loss by the connecting member 150 and improves the acoustic and / or sound pressure characteristics of the sound generated by the vibration of the vibrating member 100 by ensuring that the sound waves (or sound pressure) from the vibration of the vibrating device 130 are not dispersed by the connecting member 150 but concentrated on the vibrating member 100.

The first support member 310 can support one or more of the edges of the vibrating member 100 or the display panel and the edges of the second support member 330. In other embodiments of this specification, the first support member 310 may cover the back of the vibrating member 100 or the display panel. For example, the first support member 310 may cover the entire back of the vibrating member 100 or the display panel. For example, the first support member 310 may be a member that covers the entire back of the vibrating member 100 or the display panel.

For example, the first support member 310 may be, and is not limited to, an inner plate, a first rear structure, a first support structure, a first support cover, a first back cover, a first rear member, an inner plate, or an inner cover. For example, the first support member 310 may be omitted.

[0090] The first support member 310 may be separated from the rearmost part of the vibrating member 100 or the display panel, or from the vibrating device 130, with a gap space (GS) in between. For example, the gap space (GS) may be expressed as an air gap, a vibration space, or an acoustic tube, and is not limited to these terms.

[0091] The second support member 330 may be positioned on the back of the first support member 310.

According to other embodiments herein, the connecting member 350 may be formed as a mesh structure with an air gap between the first support member 310 and the second support member 330.

[0094] The apparatus 10 according to the embodiments of this specification may further include a middle frame 400. The middle frame 400 may be positioned between the rear edge portion of the vibrating member 100 or the display panel and the front edge portion of the support member 300. The middle frame 400 can support at least one of the edges of the display panel and the edge portion of the support member 300. The middle frame 400 may enclose one or more of the respective sides of the display panel and the support member 300. The middle frame 400 may provide a gap space (GS) between the display panel and the support member 300.

[0095] The middle frame 400 according to the embodiments of this specification may include a first support portion 410 and a second support portion 430. For example, the first support portion 410 may be a support portion, and is not limited to these terms. For example, the second support portion 430 may be a side wall portion, and is not limited to these terms.

[0096] The first support portion 410 is positioned between the rear edge portion of the vibrating member 100 or the display panel and the front edge portion of the support member 300, thereby providing a gap space (GS) between the vibrating member 100 or the display panel and the support member 300. The front surface of the first support portion 410 is coupled or can be coupled to the rear edge portion of the vibrating member 100 or the display panel via a first connecting member 401. The rear surface of the first support portion 410 is coupled or can be coupled to the front edge portion of the support member 300 via a second connecting member 403. For example, the first support portion 410 may have a single rectangular frame structure or a frame structure having the shape of multiple segmented bars, and the embodiments herein are not limited thereto.

[0097] The second support portion 430 may be positioned parallel to the thickness direction (Z) of the device (or display device).

[0098] The apparatus 10 according to the embodiments of this specification may include a panel connecting member (or connecting member) instead of the middle frame 400.

[0099] The panel connecting member is positioned between the rear edge of the vibrating member 100 and the front edge of the support member 300, thereby creating a gap space (GS) between the vibrating member 100 and the support member 300. The panel connecting member can be positioned between the rear edge of the vibrating member 100 and the front edge of the support member 300 to bond the vibrating member 100 and the support member 300.

For example, the adhesive layer of the panel connecting member can include a urethane-based material (or material) which has relatively more flexible properties than acrylic among acrylic and urethane, in order to minimize the transmission of vibrations from the vibrating member 100 to the support member 300. This can minimize the vibration of the vibrating member 100 transmitted by the support member 300.

[0100] In the apparatus 10 according to the embodiment of this specification, if a panel connecting member is included instead of the middle frame 400, the support member 300 may include a bent side wall that is bent from one side (or end) of the second support member 330 to surround one or more of the outer surfaces (or outer walls) of the first support member 310, the panel connecting member, and the vibrating member 100. The bent side wall according to the embodiment of this specification may have a single side wall structure or a hemming structure. A hemming structure may be a structure in which the ends of a member are bent into a curved shape and overlap each other or are adjacent to each other and separated. For example, to improve the aesthetic side appearance, the bent side wall may include a first bent side wall bent from one side (or end) of the second support member 330, and a second bent side wall bent from the first bent side wall between the first bent side wall and the outer surface of the vibrating member 100. The second bent sidewall can be separated from the inner surface of the first bent sidewall so as to contact the inner surface of the first bent sidewall or to mitigate the transmission of lateral external shocks to the outer surface of the vibrating member 100. This allows the second bent sidewall to mitigate the transmission of lateral external shocks to the outer surface of the vibrating member 100 or to the outer surface of the vibrating member 100.

[0101] In other embodiments of this specification, the middle frame 400 may be omitted in the apparatus 10 according to the embodiment of this specification. For example, a panel connecting member or adhesive may be provided instead of the middle frame 400. According to other embodiments of this specification, a partition may be provided instead of the middle frame 400.

[0102] The inventors of this specification have conducted numerous studies and experiments to improve the acoustic characteristics in the low-frequency range, as the acoustic characteristics and / or sound pressure characteristics in the low-frequency range are reduced when the vibration device 130 is composed of a film-type vibration device. Through these studies and experiments, they have invented a device with a new structure that can improve the acoustic characteristics and / or sound pressure characteristics in the low-frequency range. This is described below.

[0103] Figures 3A to 3F show the vibrating section according to the embodiment of this specification.

[0104] Referring to Figures 3A to 3F, the vibration device 130 according to the embodiment of this specification may include a vibration section 130a. The vibration section 130a according to the embodiment of this specification may include a first vibration section 131 and a second vibration section 132.

[0105] The first vibrating part 131 may include a first part 131a and a second part 131b. For example, the first part 131a may include an inorganic material, and the second part 131b may include an organic material. For example, the first part 131a may have piezoelectric properties, and the second part 131b may have flexible properties or flexibility. For example, the inorganic material of the first part 131a may have piezoelectric properties, and the organic material of the second part 131b may have flexible properties or flexibility. The first vibrating part 131 may include a plurality of first parts 131a and a plurality of second parts 131b. For example, a plurality of first parts 131a and a plurality of second parts 131b may be arranged alternately and repeatedly along a second direction (Y).

[0106] The second vibrating section 132 may include a first section 132a and a second section 132b. For example, the second section 132b may include an inorganic material, and the second section 132b may include an organic material. For example, the first section 132a may have piezoelectric properties, and the second section 132b may have flexible properties or flexibility. For example, the inorganic material of the first section 132a may have piezoelectric properties, and the organic material of the second section 132b may have flexible properties or flexibility. For example, the second vibrating section 132 may include a plurality of first sections 132a and a plurality of second sections 132b. For example, a plurality of first sections 132a and a plurality of second sections 132b may be arranged alternately and repeatedly along a second direction (Y).

[0107] According to the embodiments of this specification, the first vibrating part 131 and the second vibrating part 132 can each be made of a material having a crystalline structure (or an inorganic material or a piezoelectric material). For example, the first vibrating part 131 and the second vibrating part 132 can be made of materials having different crystalline structures. For example, the first vibrating part 131 can be made of a material having a single-crystal structure, and the second vibrating part 132 can be made of a material having a polycrystalline structure. For example, the first vibrating part 131 can be made of a single-crystal ceramic, and the second vibrating part 132 can be made of a polycrystalline ceramic.

[0108] According to the embodiments of this specification, the first vibrating portion 131 may be a single-crystal vibrating portion, and the second vibrating portion 132 may be a polycrystalline vibrating portion. For example, the first vibrating portion 131 may have a structure in which particles having a single crystal domain of a constant structure are regularly arranged. For example, the second vibrating portion 132 may be composed of disordered particles having diverse crystal domains.

[0109] The first vibrating section 131 can be manufactured from a vibrating element with vibration characteristics, such as a piezoelectric deformation constant (d33), that are approximately 2 to 3 times larger than those of the second vibrating section 132, thus enabling it to have high sound pressure characteristics (or acoustic characteristics) in the low-frequency range. The second vibrating section 132 has vibration characteristics that are approximately 2 to 3 times smaller than those of the first vibrating section 131, resulting in the problem of lower sound pressure characteristics in the low-frequency range. However, since it can be manufactured over a large area, it can be realized in large-scale vibrating or acoustic devices.

[0110] The inventors of this specification have conducted numerous studies and experiments to apply the first vibrating section 131 in order to improve the sound pressure characteristics in the low-frequency range that occur when implementing a vibrating device with the second vibrating section 132. Through these studies and experiments, they have invented a vibrating device including the first vibrating section 131 and the second vibrating section 132, which will be described below.

[0111] The vibration device 130 according to the embodiments of this specification can vibrate by repeatedly contracting and expanding alternately due to the piezoelectric effect (or piezoelectric properties). The vibration device 130 according to the embodiments of this specification can directly vibrate the vibrating member 100 or the display panel by vibrating in the thickness direction (Z) by repeatedly contracting and expanding alternately due to the inverse piezoelectric effect. For example, the vibration device 130 may be, but is not limited to, a vibration film, a displacement generator, a displacement film, an acoustic generator, a vibration array, a vibration array section, a vibration structure array section, or a vibration array structure. The first vibrating section 131 and the second vibrating section 132 may be, but is not limited to, a piezoelectric vibrating section, a piezoelectric vibrating layer, a displacement section, a piezoelectric displacement section, a piezoelectric displacement layer, an acoustic wave generating section, a vibration layer, a piezoelectric material layer, a piezoelectric composite layer, an electroactive layer, a piezoelectric material section, a piezoelectric composite section, an electroactive section, a piezoelectric structure, a piezoelectric composite, or a piezoelectric ceramic composite. Each of the first vibrating section 131 and the second vibrating section 132 according to the embodiments of this specification may have a 2-2 composite structure. The first part 131a of the first vibrating section 131 and the first part 132a of the second vibrating section 132 according to the embodiments of this specification may be composed of an inorganic material. For example, the first part 131a of the first vibrating section 131 and the first part 132a of the second vibrating section 132 may be, but are not limited to, a piezoelectric section, piezoelectric body, inorganic section, inorganic material, piezoelectric layer, vibration layer, displacement layer, or displacement body.

[0112] According to the embodiments herein, the first portion 131a of the first vibrating portion 131 and the first portion 132a of the second vibrating portion 132 may be composed of a ceramic series of materials capable of achieving relatively high vibrations, and / or piezoelectric ceramics having a perovskite series crystal structure. The perovskite crystal structure may be an oriented, plate-like structure having piezoelectric and inverse piezoelectric effects. The perovskite crystal structure is represented by the chemical formula ABO3, where the A site consists of a divalent metallic element and the B site consists of a tetravalent metallic element. For example, in the chemical formula ABO3, the A and B sites may be cations, and O may be an anion. For example, the chemical formula ABO3 may include at least one of PbTiO3, PbZrO3, PbZrTiO3, BaTiO3, and SrTiO3, and the embodiments herein are not limited thereto.

[0113] In perovskite crystal structures, the position of the central ion, for example, titanium (Ti) ions in the case of PbTiO3, changes due to external stress or a magnetic field, altering the polarization and generating a piezoelectric effect. For example, a perovskite crystal structure can generate a piezoelectric effect by changing from a symmetric cubic shape to an unsymmetric shape such as a tetragonal, orthorhombic, or rhombohedral shape due to external stress or a magnetic field. High polarization and easy polarization rearrangement at the morphotropic phase boundaries of tetragonal and rhombohedral structures can result in high piezoelectric properties.

[0114] According to the examples herein, the inorganic material portion comprising each of the plurality of first parts 131a, 132a may include one or more of lead (Pb), zirconium (Zr), titanium (Ti), zinc (Zn), nickel (Ni), niobium (Nb), magnesium (Mg), manganese (Mn), and indium (In), and the examples herein are not limited thereto.

[0115] According to other embodiments of this specification, the inorganic material portion comprising each of the plurality of first parts 131a, 132a may include a PZT (lead zirconate titanate) system containing lead (Pb), zirconium (Zr), and titanium (Ti), or a PZNN (lead zirconate nikel niobate) system containing lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb), and the embodiments of this specification are not limited thereto. According to other embodiments of this specification, the inorganic material portion comprising each of the plurality of first parts 131a, 132a may include a PMN (lead magnesium niobate) system, a PNN (lead nikel niobate) system, a PZN (lead zirconate niobate) system, or a PIN (lead indium niobate) system, and the embodiments of this specification are not limited thereto. PZN-based materials may contain lead (Pb), zirconium (Zr), and niobium (Nb), for example, Pb(Zr,Nb)O3. PMN-based materials may contain lead (Pb), magnesium (Mg), and niobium (Nb), for example, Pb(Mg,Nb)O3. PNN-based materials may contain lead (Pb), nickel (Ni), and niobium (Nb), for example, Pb(Ni,Nb)O3. PZN-based materials may contain lead (Pb), zirconium (Zr), and niobium (Nb), for example, Pb(Zr,Nb)O3. PIN-based materials may contain lead (Pb), indium (In), and niobium (Nb), for example, Pb(In,Nb)O3. According to other examples herein, the inorganic material portion comprising each of the plurality of first parts 131a, 132a may include at least one of lead (Pb)-free CaTiO3, BaTiO3, and SrTiO3, but the examples herein are not limited to these.

[0116] According to other embodiments of this specification, each inorganic material portion comprising a plurality of first parts 131a, 132a has a piezoelectric deformation coefficient (d) along the thickness direction (Z). 33) can have 1,000 pC / N or more. When applying the vibration device to a display panel or a vibration member (or an object to be vibrated) with a large size, in order to have sufficient vibration characteristics or piezoelectric characteristics, it is necessary to have a high piezoelectric strain coefficient (d 33 ). For example, in order to have a high piezoelectric strain coefficient (d 33 ), the inorganic material part can contain a PZT-based material (PbZrTiO3) as a main component, a softener dopant material doped into the A site (Pb), and a relaxor ferroelectric material doped into the B site (ZrTi).

[0117] The softener dopant material can improve the piezoelectric and dielectric characteristics of the inorganic material part. For example, it can increase the piezoelectric strain coefficient (d 33 ) of the inorganic material part. The softener dopant material according to the examples in this specification can contain divalent to trivalent elements. Since the PZT-based material (PbZrTiO3) can contain the softener dopant material to form a morphotropic phase boundary (MPB), the piezoelectric and dielectric characteristics can be improved. For example, the softener dopant material can contain strontium (Sr), barium (Ba), lanthanum (La), neodymium (Nd), calcium (Ca), yttrium (Y), erbium (Er), or ytterbium (Yb). For example, the ions (Sr 2+ , Ba 2+ , La 2+ , Nd 3+ , Ca 2+ , Y 3+ , Er 3+ , Yb 3+ ) of the softener dopant material doped into the PZT-based material (PbZrTiO3) replace a part of lead (Pb) in the PZT-based material (PbZrTiO3), and the replacement amount can be 2 to 20 mol%. For example, when the replacement amount is less than 2 mol% or exceeds 20 mol%, the perovskite crystal structure collapses, so the electromechanical coupling coefficient (kP) and the piezoelectric strain coefficient (d 33) may decrease. When a softener dopant material is substituted, a morphotropic phase boundary can be formed, and since high piezoelectric and dielectric properties can be obtained at the morphotropic phase boundary, a vibrating device with high piezoelectric and dielectric properties can be realized.

[0118] According to the examples herein, a relaxor ferroelectric material doped with a PZT-based material (PbZrTiO3) can improve the electrical deformation properties of the inorganic material portion. The relaxor ferroelectric materials according to the examples herein may include, but are not limited to, PMN (lead magnesium niobate)-based materials, PNN (lead nickel niobate)-based materials, PZN (lead zirconate niobate)-based materials, or PIN (lead indium niobate)-based materials. The PMN-based material may include lead (Pb), magnesium (Mg), and niobium (Nb), for example, Pb(Mg,Nb)O3. The PNN-based material may include lead (Pb), nickel (Ni), and niobium (Nb), for example, Pb(Ni,Nb)O3. PZN-based materials can contain lead (Pb), zirconium (Zr), and niobium (Nb), for example, Pb(Zr,Nb)O3. PIN-based materials can contain lead (Pb), indium (In), and niobium (Nb), for example, Pb(In,Nb)O3. For example, a relaxor ferroelectric material doped with a PZT-based material (PbZrTiO3) substitutes a portion of zirconium (Zr) and titanium (Ti) in the PZT-based material (PbZrTiO3), with the substitution amount being 5-25 mol%. For example, if the substitution amount is less than 5 mol% or greater than 25 mol%, the perovskite crystal structure collapses, and the electrical coupling coefficient (kP) and piezoelectric deformation coefficient (d 33 ) may decrease.

[0119] According to the embodiments herein, the inorganic material portion comprising each of the plurality of first parts 131a, 132a may further contain a donor material doped at the B site (ZrTi) of the PZT-based material (PbZrTiO3) for additional improvement of the piezoelectric deformation coefficient. For example, the donor material doped at the B site (ZrTi) may include elements with a valency of +4 to +6. For example, the donor material doped at the B site (ZrTi) may include tellurium (Te), germanium (Ge), uranium (U), niobium (Nb), tantalum (Ta), antimony (Sb), or tungsten (W).

[0120] Each of the multiple first parts 131a, 132a according to the embodiments herein has an inorganic material portion which has a piezoelectric deformation coefficient (d) along the thickness direction (Z). 33 Since it can have a vibration of 1,000 pC / N or more in this case, a vibration device with improved vibration characteristics can be realized. For example, a vibration device with improved vibration characteristics can be realized in a large-area device or a large-area vibrating member (or object to be vibrated).

[0121] Each of the second portion 131b of the first vibrating section 131 and the second portion 132b of the second vibrating section 132 according to the embodiments herein may be composed of an organic material portion. For example, by arranging the organic material portion between inorganic material portions, it is possible to absorb the shock applied to the inorganic material portion (or the first portion), relieve the stress concentrated in the inorganic material portion, improve the durability of the first and second vibrating sections 131, 132 or the vibrating device 130, and provide flexibility to the first and second vibrating sections 131, 132 or the vibrating device 130.

[0122] Each of the second portion 131b of the first vibrating section 131 and the second portion 132b of the second vibrating section 132 according to the embodiments of this specification can have a lower modulus and viscoelasticity compared to the first portion 131a of the first vibrating section 131 and the first portion 132a of the second vibrating section 132. This improves the reliability of the first portion 131a of the first vibrating section 131 and the first portion 132a of the second vibrating section 132, which are susceptible to impact due to their brittle properties. For example, the second portion 131b of the first vibrating section 131 and the second portion 132b of the second vibrating section 132 may be composed of a material having a loss coefficient of 0.01 to 1 and a modulus of 0.1 to 10 [Gpa (gigapascal)].

[0123] The organic material portion comprising the second part 131b of the first vibrating section 131 and the second part 132b of the second vibrating section 132 may include an organic substance, organic polymer, organic piezoelectric material, or organic non-piezoelectric material having flexible or pliable properties compared to the inorganic material portion comprising the first part 131a of the first vibrating section 131 and the first part 132a of the second vibrating section 132. For example, the second part 131b of the first vibrating section 131 and the second part 132b of the second vibrating section 132 can be described as an organic part, organic material, adhesive part, expandable part, bendable part, damping part, elastic part, resilient part, or pliable part, and the embodiments herein are not limited thereto.

[0124] The second portion 131b of the first vibrating section 131 according to the embodiments of this specification may include an organic material portion with a different modulus from the second portion 132b of the second vibrating section 132. The modulus may be Young's modulus. For example, it has been recognized that if the second portion 131b of the first vibrating section 131 and the second portion 132b of the second vibrating section 132 are composed of materials having the same modulus, the first vibrating section 131 has the problem of not being able to output the desired sound.

[0125] According to the embodiments of this specification, the second portion 132b of the second vibrating section 132 can be made of an epoxy material with a high modulus (e.g., 0.1 to 10 GPa). It was recognized that if the second portion 131b of the first vibrating section 131 is made of the same high modulus (e.g., 0.1 to 10 GPa) epoxy material as the second portion 132b of the second vibrating section 132, the displacement of the first vibrating section 131 cannot be maximized, and therefore the desired sound cannot be produced. Accordingly, in order to maximize the displacement of the first vibrating section 131, the second portion 131b of the first vibrating section 131 can be made of a softer material than the second portion 132b of the second vibrating section 132.

[0126] According to the embodiments of this specification, the modulus of the second portion 131b of the first vibrating section 131 can be made of a different material than the modulus of the second portion 132b of the second vibrating section 132. For example, the modulus of the second portion 131b of the first vibrating section 131 can be made of a material that is smaller (or lower) than the modulus of the second portion 132b of the second vibrating section 132. The modulus of the second portion 131b of the first vibrating section 131 can be 0.1 to 100 MPa (megapascal), and the embodiments of this specification are not limited thereto. For example, the second portion 131b of the first vibrating section 131 can be made of a different resin material than the second portion 132b of the second vibrating section 132. For example, the second portion 131b of the first vibrating section 131 can be made of a material softer than epoxy resin. For example, the second portion 131b of the first vibrating section 131 can be made of silicone resin, and the embodiments herein are not limited thereto. For example, the modulus of the second portion 132b of the second vibrating section 132 can be 0.1 to 10 GPa, and the embodiments herein are not limited thereto. For example, the second portion 132b of the second vibrating section 132 can be made of epoxy resin. Therefore, the vibration displacement of the first vibrating section 131 can be maximized, so that low-frequency sounds can be output. For example, in order to solve the problem of reduced low-frequency sounds that occurs when the second vibrating section 132 is used, the vibrating device 130 is configured to include the first vibrating section 131, so that the low-frequency sound characteristics can be complemented.

[0127] According to the embodiments of this specification, by configuring the vibration device 130 to include a first vibrating section 131 and a second vibrating section 132, the acoustic characteristics in the low-frequency range can be improved, and thus a vibration device 130 that covers both the low-frequency range and the high-frequency range can be provided.

[0128] Furthermore, according to the embodiments of this specification, by configuring the vibration device 130 to include a first vibrating section 131 and a second vibrating section 132, the acoustic characteristics and / or sound pressure characteristics in the low-frequency range are complemented by the first vibrating section 131, and the acoustic characteristics and / or sound pressure characteristics in the high-frequency range are complemented by the second vibrating section 132, thereby providing a vibration device 130 that can output uniform sound across the entire frequency range from the low-frequency range to the high-frequency range.

[0129] Furthermore, according to the embodiments of this specification, since the second portion 131b of the first vibrating part 131 and the second portion 132b of the second vibrating part 132 are made of materials having different modulos, the acoustic characteristics and / or sound pressure characteristics of the first vibrating part 131 in the low-frequency range can be improved.

[0130] According to the embodiments of this specification, the second portion 131b of the first vibrating portion 131 can be represented by the following Equation 1.

[0131] [Formula 1] TIFF0007867943000001.tif25170

[0132] According to the embodiments of this specification, the second portion 132b of the second vibrating section 132 can be represented by the following equation 2.

[0133] [Formula 2] TIFF0007867943000002.tif14170

[0134] Referring to Figures 3A to 3D, the vibrating device 130 according to the embodiment of this specification may include a first vibrating section 131 and a second vibrating section 132. As shown in Figures 3A and 3C, by increasing or making the fraction of the first vibrating section 131 higher (or greater) than the fraction of the second vibrating section 132, the low-frequency sound can be increased or made higher (or greater) than the high-frequency sound. For example, the fraction may be the ratio of the volume occupied by the second vibrating section 132 to that of the first vibrating section 131, and the thicknesses of the first vibrating section 131 and the second vibrating section 132 may be the same. For example, the fraction may be size or area. Figures 3B and 3D show configurations in which the positions of the first vibrating section 131 and the second vibrating section 132 are different from those in Figures 3A and 3C. For example, as shown in Figures 3B and 3D, the positions of the first vibrating section 131 and the second vibrating section 132 can be configured in the opposite way to those in Figures 3A and 3C.

[0135] Referring to Figures 3E and 3F, by configuring the fractions of the first vibrating part 131 and the second vibrating part 132 to be the same, it is possible to achieve sound in the low-frequency range to the high-frequency range. Figure 3E shows a configuration in which the positions of the first vibrating part 131 and the second vibrating part 132 are different from those in Figure 3F. For example, as shown in Figure 3E, the positions of the first vibrating part 131 and the second vibrating part 132 can be configured in the opposite direction to those in Figure 3F.

[0136] According to embodiments of this specification, a device can be provided that can adjust the acoustics of a desired frequency range by adjusting the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132. For example, by configuring the fraction (or magnitude) of the first vibrating part 131 to be greater than or the same as the fraction (or magnitude) of the second vibrating part 132, a device can be provided in which the acoustics of the low frequency range are enhanced more than those of the high frequency range, or a device can be provided that realizes acoustics in the low frequency range to the high frequency range. For example, since the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132 can be adjusted according to the sound pressure characteristics and / or acoustic characteristics required of the vibrating device 130, there is an advantage that the design of the vibrating device 130 is easy.

[0137] Furthermore, the vibrating device 130 according to the embodiment of this specification can be realized in a thin film shape by alternately and repeatedly connecting first parts 131a, 132a having piezoelectric properties and second parts 131b, 132b having flexibility, thereby allowing it to be bent into a shape corresponding to the shape of the support member or the object to be vibrated. For example, when the vibrating device 130 is connected or coupled to a vibrating member 100 including various curved surfaces via a connecting member 150, it can be bent into a curved shape along the shape of the curved surface of the vibrating member 100, and its reliability will not be reduced such as by damage or breakage even when bent into a curved shape.

[0138] Figures 4A to 4D show vibrating parts according to other embodiments of this specification.

[0139] Referring to Figures 4A to 4D, the vibration device 130 according to other embodiments of this specification may include a vibration section 130a. The vibration section 130a according to other embodiments of this specification may include a first vibration section 131 and a second vibration section 132.

[0140] Referring to Figures 4A to 4D, by increasing or making the fraction of the second vibrating part 132 higher (or greater) than the fraction of the first vibrating part 131, it is possible to increase or make the high-frequency sound higher (or greater) than the low-frequency sound. Figures 4B and 4D show configurations in which the positions of the first vibrating part 131 and the second vibrating part 132 are different from those in Figures 4A and 4C. For example, as shown in Figures 4B and 4D, the positions of the first vibrating part 131 and the second vibrating part 132 can be configured in the opposite direction to those in Figures 4A and 4C.

[0141] According to embodiments of this specification, a device can be provided that can adjust the acoustics of a desired frequency range by adjusting the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132. For example, by configuring the fraction (or magnitude) of the second vibrating part 132 to be larger than that of the first vibrating part 131, a device can be provided in which the acoustics of the low frequency range are enhanced more than those of the high frequency range. For example, since the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132 can be adjusted according to the sound pressure characteristics and / or acoustic characteristics required of the vibrating device 130, there is an advantage that the design of the vibrating device 130 is easy.

[0142] Figures 5A to 5D show a vibrating section according to another embodiment of this specification.

[0143] Referring to Figures 5A to 5D, the vibration device 130 according to other embodiments of this specification may include a vibration section 130a. The vibration section 130a according to other embodiments of this specification may include a first vibration section 131 and a second vibration section 132.

[0144] Referring to Figure 5A, the first vibrating part 131 may be positioned in the center of the second vibrating part 132. For example, the second vibrating part 132 may surround the first vibrating part 131. For example, the second vibrating part 132 may be positioned outside the first vibrating part 131. According to the embodiments of this specification, since the first vibrating part 131 is positioned in the center of the second vibrating part 132, it is possible to have a more balanced sound pressure characteristic of low and high frequencies than when a single vibrating device (e.g., the first vibrating part 131 or the second vibrating part 132) is used. Furthermore, in the case of low frequencies, the wavelength is long and the directivity is weaker compared to high frequencies, so when implemented in a vibrating device (or acoustic device), it may cause discomfort due to vibration. Therefore, compared to when only the first vibrating part 131 is used, it is possible to reduce discomfort from low frequencies while simultaneously enhancing high frequencies.

[0145] Referring to Figures 5B to 5D, the vibrating section 130a according to other embodiments of this specification may include a first vibrating section 131 and two second vibrating sections 132. Referring to Figures 5B and 5D, the two second vibrating sections 132 may be arranged on either side of the first vibrating section 131. For example, the two second vibrating sections 132 may be arranged with the first vibrating section 131 in between. This makes it possible to realize a vibrating device that includes sounds in the low-frequency to high-frequency range.

[0146] Referring to Figure 5B, since the two second vibrating parts 132 are arranged with the first vibrating part 131 in between, the acoustics in the high-frequency range can be further improved. According to the embodiment of this specification, since the first vibrating part 131 is arranged on both sides of the second vibrating part 132, it is possible to have a more balanced sound pressure characteristic of low and high frequencies than when a single vibrating device (e.g., the first vibrating part 131 or the second vibrating part 132) is used. Furthermore, in the case of low frequencies, the wavelength is long and the directivity is weaker compared to high frequencies, so when implemented in a vibrating device (or acoustic device), it can cause discomfort due to vibration. Therefore, compared to when only the first vibrating part 131 is used, it is possible to reduce discomfort from low frequencies while simultaneously enhancing high frequencies. Furthermore, according to the embodiments of this specification, the first vibrating section 131 can enhance bass frequencies, thereby improving the bass-range acoustics produced by the first vibrating section 131, and the second vibrating section 132 outputs high-frequency acoustics, thereby improving the high-frequency acoustics produced by the two second vibrating sections 132.

[0147] Referring to Figure 5D, by configuring the fraction (or magnitude) of the first vibrating part 131 to be smaller than the fractions of the two second vibrating parts 132, it is possible to provide a device that realizes acoustics in the low-frequency range to the high-frequency range. According to the embodiment of this specification, since the second vibrating parts 132 are arranged on both sides of the first vibrating part 131, it is possible to have a more balanced sound pressure characteristic of low and high frequencies than when a single vibrating device (e.g., the first vibrating part 131 or the second vibrating parts 132) is used. The manufacturing cost of the first vibrating part 131 may be higher than that of the second vibrating parts 132. Compared to Figure 5B, as the fraction (or magnitude) of the first vibrating part 131 decreases, the bass decreases, but there is the advantage of lower manufacturing costs. By finding the trade-off point between manufacturing cost and the bass enhancement effect, the degree of freedom in manufacturing the vibrating device 130 can be improved depending on the application of the vibrating device 130 and the manufacturing cost.

[0148] Referring to Figure 5C, two first vibrating parts 131 can be arranged on both sides of the second vibrating part 132. For example, two first vibrating parts 131 can be arranged with the second vibrating part 132 in between. This makes it possible to realize a vibration device that includes sounds in the low-frequency range to the high-frequency range. According to the embodiments of this specification, since the first vibrating parts 131 are arranged on both sides of the second vibrating part 132, it is possible to have a more balanced sound pressure characteristic of low and high frequencies than when the device is composed of a single vibration device (e.g., the first vibrating part 131 or the second vibrating part 132). Furthermore, in the case of high frequencies, there is a disadvantage that the wavelength is shorter compared to low frequencies and sound cannot be transmitted over long distances, but when implemented in a vibration device (or sound device), the addition of the first vibrating parts 131 makes it possible to extend the sound transmission distance of the vibration device (or sound device or speaker) and also enhance the bass. Furthermore, according to the embodiments of this specification, since the two first vibrating parts 131 are arranged with the second vibrating part 132 in between, the sound in the low-frequency range can be further improved. Furthermore, according to the embodiments of this specification, the first vibrating part 131 can enhance the bass, thus improving the sound in the low-frequency range produced by the first vibrating part 131, and the second vibrating part 132 outputs high-frequency sound, thus improving the sound in the high-frequency range produced by the two second vibrating parts 132.

[0149] According to the embodiments of this specification, a device can be provided that can adjust the acoustics of a desired frequency range by adjusting the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132. For example, since the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132 can be adjusted according to the sound pressure characteristics and / or acoustic characteristics required of the vibrating device 130, there is an advantage that the design of the vibrating device 130 is easy.

[0150] Figure 6 shows a vibrating section according to another embodiment of this specification.

[0151] Referring to Figure 6, the vibrating section 130a of the vibrating device 130 according to the embodiment of this specification may further include a first layer 133. For example, the first layer 133 may be positioned between the first vibrating section 131 and the second vibrating section 132. The first layer 133 can prevent vibration interference between the first vibrating section 131 and the second vibrating section 132. For example, the first layer 133 can prevent acoustic and / or sound pressure interference between the first vibrating section 131 and the second vibrating section 132. The first layer 133 may be, but is not limited to, an intermediate layer, a metal boundary layer, a boundary layer, a vibration interference prevention layer, or an acoustic interference prevention layer. The first layer 133 may be, but is not limited to, a metal layer. For example, the first layer 133 may include, but is not limited to, one or more of aluminum (Al), Al alloys, copper (Cu), and Cu alloys.

[0152] According to embodiments of this specification, the first layer 133 may be positioned at a distance from the first vibrating portion 131. The first layer 133 may be positioned at a distance from the second vibrating portion 132. For example, the first vibrating portion 131 may be positioned at a distance from the second vibrating portion 132. For example, the first vibrating portion 131 may be positioned at a distance from the second vibrating portion 132 with the first layer 133 in between. The size of the first layer 133 may be set within a range in which the vibrations between the first vibrating portion 131 and the second vibrating portion 132 do not interfere with each other. For example, the size of the first layer 133 may be smaller than the size of at least one of the first portion 131a of the first vibrating portion 131 and the first portion 132a of the second vibrating portion 132. For example, the area of ​​the first layer 133 may be larger than the area of ​​at least one of the second portion 131b of the first vibrating part 131 and the second portion 132b of the second vibrating part 132. For example, the area of ​​the first layer 133 may be 0.1 mm to 5 mm, and the embodiments of this specification are not limited thereto.

[0153] According to the embodiments of this specification, the first distance d1 between the first vibrating part 131 and the first layer 133 can be set so as not to suppress the vibration of the first vibrating part 131 to the maximum extent. For example, the first distance d1 between the first vibrating part 131 and the first layer 133 may be 50 μm to 1 mm, and the embodiments of this specification are not limited thereto. For example, the second distance (D2) between the second vibrating part 132 and the first layer 133 can be set so as not to suppress the vibration of the second vibrating part 132 to the maximum extent. The second distance (D2) between the second vibrating part 132 and the first layer 133 may be 50 μm to 1 mm, and the embodiments of this specification are not limited thereto. For example, the first distance (D1) may be the same as or substantially the same as the second distance (D2), and the embodiments of this specification are not limited thereto.

[0154] According to the embodiments of this specification, by configuring a first layer 133 between the first vibrating part 131 and the second vibrating part 132, vibration interference between the first vibrating part 131 and the second vibrating part 132 can be prevented, thereby providing a vibrating device that can deliver clearer sound.

[0155] Figure 7 shows an apparatus according to another embodiment of this specification. Figure 8 is a cross-sectional view along the line B-B' shown in Figure 7.

[0156] Referring to Figures 7 and 8, the vibration device 130 according to the embodiments of this specification can be represented as a flexible vibration structure, flexible vibrator, flexible vibration generating element, flexible vibration generator, flexible acoustic device, flexible acoustic element, flexible acoustic generating element, flexible acoustic generator, flexible actuator, flexible speaker, flexible piezoelectric speaker, film actuator, film-type piezoelectric composite actuator, film speaker, film-type piezoelectric speaker, or film-type piezoelectric composite speaker, and the embodiments of this specification are not limited thereto.

[0157] Referring to Figures 7 and 8, the vibrating device 130 according to the embodiments of this specification may include a vibrating section 130a, a first electrode section 130b, and a second electrode section 130c. Since the vibrating section 130a is identical or substantially identical to the vibrating section 130a described with reference to Figures 3A to 6, redundant explanations of it can be omitted. For example, the vibrating section 130a may include at least one of the vibrating sections 130a of the vibrating device 130 shown in Figures 3A to 6.

[0158] The first electrode portion 130b may be positioned on the first surface (or top surface) of the vibrating portion 130a. For example, the first electrode portion 130b may be positioned in common with or coupled to the first surfaces of each of the multiple first portions 131a and each of the multiple second portions 131b of the first vibrating portion 131. For example, the first electrode portion 130b may be electrically coupled to the first surfaces of each of the multiple first portions 131a and each of the multiple second portions 131b of the first vibrating portion 131. For example, the first electrode portion 130b may be positioned in common with or coupled to the first surfaces of each of the multiple first portions 132a and each of the multiple second portions 132b of the second vibrating portion 132. For example, the first electrode portion 130b may be electrically coupled to the first surfaces of each of the multiple first portions 132a and each of the multiple second portions 132b of the second vibrating portion 132. For example, the first electrode portion 130b may have the shape of a single electrode arranged across the entire first surface of the vibrating portion 130a. For example, the first electrode portion 130b may have substantially the same shape (or size) as the vibrating portion 130a, and the embodiments herein are not limited thereto.

[0159] The first electrode portion 130b in the embodiments of this specification may consist of a transparent conductive material, a translucent conductive material, or an opaque conductive material. For example, the transparent or translucent conductive material may include one or more of ITO (indium tin oxide) or IZO (indium zinc oxide), and the embodiments of this specification are not limited thereto. The opaque conductive material may consist of one or more of aluminum (Al), copper (Cu), gold (Au), silver (Ag), molybdenum (Mo), or magnesium (Mg), or an alloy thereof, and the embodiments of this specification are not limited thereto.

[0160] The second electrode portion 130c may be positioned on a different (or opposite) surface of the first surface of the vibrating portion 130a. For example, the second electrode portion 130c may be positioned on a second surface (or back surface) of the vibrating portion 130a that is different (or opposite) to the first surface. For example, the second electrode portion 130c may be positioned in common with or coupled to the second surfaces of each of the multiple first portions 131a and each of the multiple second portions 131b of the first vibrating portion 131. For example, the second electrode portion 130c may be electrically coupled to the first surfaces of each of the multiple first portions 131a and each of the multiple second portions 131b of the first vibrating portion 131. For example, the second electrode portion 130c may be positioned in common with or coupled to the second surfaces of each of the multiple first portions 132a and each of the multiple second portions 132b of the second vibrating portion 132. For example, the second electrode portion 130c may be electrically connected to the second surfaces of each of the multiple first portions 132a and multiple second portions 132b of the second vibrating portion 132. For example, the second electrode portion 130c may have the shape of a single electrode arranged across the entire second surface of the vibrating portion 130a.

For example, the vibrating part 130a can vibrate by repeatedly contracting and expanding alternately due to the inverse piezoelectric effect of an acoustic signal (or voice signal or drive signal) applied to the first electrode part 130b and the second electrode part 130c from the outside. For example, the vibrating part 130a can vibrate by vertical vibration and planar vibration due to an acoustic signal applied to the first electrode part 130b and the second electrode part 130c. The vibrating part 130a can increase the displacement of the vibrating member (or diaphragm or object to be vibrated) by contraction and expansion in the planar direction, thereby further improving the vibration of the vibrating member.

Thus, the first cover member 130d can protect the first electrode portion 130b.

[0165] The second cover member 130e may be positioned on the second surface of the vibrating portion 130a. For example, the second cover member 130e may be positioned on the second electrode portion 130c. For example, the second cover member 130e may be configured to cover the second electrode portion 130c. Thus, the second cover member 130e can protect the second electrode portion 130c.

For example, the vibrating portion 130a, the first electrode portion 130b, and the second electrode portion 130c may be embedded or incorporated between the first adhesive layer 130f and the second adhesive layer 130g.

[0170] Each of the first adhesive layer 130f and the second adhesive layer 130g in the examples of this specification may contain an electrically insulating material that is compressible and resilient while maintaining adhesive properties. For example, each of the first adhesive layer 130f and the second adhesive layer 130g may contain an epoxy resin, an acrylic resin, a silicone resin, or a urethane resin, and the examples of this specification are not limited thereto.

[0172] The method for manufacturing the first vibrating section 131 according to the embodiments of this specification is as follows.

[0173] The first vibrating section 131 can be formed by solid-state crystal growth, but the examples herein are not limited thereto. For example, solid-state crystal growth may involve mixing powders such as ceramics, attaching a single-crystal seed, and growing a polycrystalline material into a single crystal through a sintering process. For example, the single-crystal seed may be BaTi x Zr (1-x) The material may be O3, and the examples herein are not limited thereto. This method involves mixing and grinding a powder such as ceramic and then plasticizing it. The plasticizing temperature may be 800°C, and the examples herein are not limited thereto. Then, a secondary material is mixed and ground. For example, the secondary material may be a lead (Pb) compensation material, and the examples herein are not limited thereto. Then, pellets (particles) are produced and sintered. Then, the first vibrating section 131 is manufactured by inducing the growth of the mixture using a seed template (e.g., polycrystalline) and carrying out crystal growth and lead (Pb) compensation. Crystal growth and lead (Pb) compensation can be carried out at a temperature of 900°C or higher for 200 hours or more, and the examples herein are not limited thereto.

[0174] The first vibrating section 131 according to other embodiments of this specification may be formed by the Bridgman method. For example, the Bridgman method may be a method in which a powder mixture of ceramics or the like is melted into a liquid state at a high temperature, and then a single crystal is grown from a small single crystal nucleus. To describe this method, the powder of ceramics or the like is mixed and pulverized, and then melted. The melting temperature may be 1300°C to 1700°C, and the embodiments of this specification are not limited to this. Then, the first vibrating section 131 is manufactured by causing crystallization of the molten material while lowering the temperature, and growing a single crystal. The crystallization temperature may be 800°C to 1400°C, and the embodiments of this specification are not limited to this.

[0175] The manufacturing method for the vibration device 130, including the first vibrating section 131 and the second vibrating section 132 according to other embodiments of this specification, is described below. Since the manufacturing method for the second vibrating section 132 is the same as or substantially the same as the manufacturing method for the first vibrating section 131, the manufacturing method for the first vibrating section 131 will be described as an example.

[0176] A substrate material of a plate-shaped inorganic substance having piezoelectric properties is manufactured through the preceding process.

[0177] The prior steps in the embodiments of this specification involve mixing and drying ceramic raw materials, crystallizing the crystalline structure through a plasticity step, and producing a plate-shaped inorganic matrix through at least one molding step and a sintering step. For example, the plate-shaped inorganic matrix may include piezoelectric ceramics having a perovskite-based crystalline structure. Heat, pressure, and spark plasma can be used in the sintering step.

[0178] Multiple cut first parts 131a are produced from each of multiple inorganic material base materials by cutting the inorganic material base material into units of predetermined size through a cutting process. For example, the cutting process can be carried out by at least one of the following methods: wire sawing, scribing, blade dicing, laser cutting, stealth dicing, and TLS (Thermal Laser Seperation), and the embodiments herein are not limited thereto. Multiple second parts 131b are then injected between the multiple first parts 131a and the multiple second parts 131b are cured.

[0179] The second vibrating section 132 is manufactured in the same manner as described above.

[0180] Next, a first electrode portion 130b is formed on the first surface of the first vibrating portion 131 and the second vibrating portion 132, and a second electrode portion 130c is formed on the second surface of the first vibrating portion 131 and the second vibrating portion 132 opposite to the first surface.

[0181] Next, polarization is formed in each of the multiple first parts 131a, 132a arranged in the first vibrating part 131 and the second vibrating part 132 through a polarization process in which a constant voltage is applied to the first electrode part 130b and the second electrode part 130c in an atmosphere of constant temperature or a temperature atmosphere that changes from high to room temperature.

[0182] Next, pads are formed to connect to the first electrode portion 130b and the second electrode portion 130c, respectively, and cover members 130d and 130e are formed to cover the first electrode portion 130b and the second electrode portion 130c, respectively, thereby completing the post-processing of the vibration device 130.

[0183] A method for manufacturing a vibrating device 130 including a first vibrating section 131 and a second vibrating section 132 according to other embodiments of this specification is described below.

[0184] By growing polycrystals in a solid state, the process can be stopped at, for example, 50% or less of the manufacturing stage (e.g., 20% to 80%) before the polycrystals become 100% single crystals. After collecting the ceramic material containing the mixed single and polycrystal portions, a vibrating device including the first vibrating section 131 and the second vibrating section 132 can be manufactured.

The description of the vibrating device 130 is the same or substantially the same as that described in Figures 7 and 8, so the same reference numerals are used, and redundant descriptions thereof can be omitted.

In another embodiment of this specification, the second power supply line (PL2) may be electrically connected to the second electrode portion 130c via a conductive material (or particles) contained in the second adhesive layer 130g.

[0191] The vibrator 130 according to the embodiments of this specification may further include a pad portion electrically connected to a first power supply line (PL1) and a second power supply line (PL2). The pad portion may be configured on one edge portion of either the first cover member 130d or the second cover member 130e so as to be electrically connected to one side (or end) of the first power supply line (PL1) and the second power supply line (PL2).

[0192] The pad portion according to the embodiments of this specification may include a first pad electrode electrically connected to one end (or one side) of a first power supply line (PL1), and a second pad electrode electrically connected to one end (or one side) of a second power supply line (PL2).

[0193] The first pad electrode is positioned on one edge portion of either the first cover member 130d or the second cover member 130e and can be connected to one end (or one side) of the first power supply line (PL1). For example, the first pad electrode can be electrically connected to one end (or one side) of the first power supply line (PL1) by passing through either the first cover member 130d or the second cover member 130e.

[0194] The second pad electrode is positioned alongside the first pad electrode and may be connected to one end (or side) of the second power supply line (PL2). For example, the second pad electrode may be electrically connected to one end (or side) of the second power supply line (PL2) by passing through either the first cover member 130d or the second cover member 130e.

[0195] According to the embodiments of this specification, the first power supply line (PL1), the second power supply line (PL2), and the pad portion may each be configured to be transparent, translucent, or opaque.

[0196] The pad portion according to the embodiments of this specification can be electrically connected to a signal cable.

[0197] The signal cable is electrically connected to a pad portion located on the vibration device 130 and can supply vibration drive signals (or acoustic signals or voice signals) provided from the acoustic processing circuit to the vibration device 130. The signal cable according to the embodiments of this specification may include a first terminal and a second terminal.

[0199] Figure 11 shows an apparatus according to another embodiment of this specification.

[0200] Referring to Figure 11, the vibration device 130 according to other embodiments of this specification may include at least two or more vibration generating units 1301, 1302. For example, the vibration device 130 according to other embodiments of this specification may include first and second vibration generating units 1301, 1302.

[0201] The first and second vibration generating units 1301 and 1302 can each be arranged electrically isolated from each other while being spaced apart along a first direction (X). Each of the first and second vibration generating units 1301 and 1302 can vibrate by repeatedly contracting and expanding alternately due to the piezoelectric effect. For example, the first and second vibration generating units 1301 and 1302 can be arranged at a first interval (D1) along the first direction (X) or tiled. Thus, the vibration device 130 in which the first and second vibration generating units 1301 and 1302 are tiled can be a vibration array, a vibration array section, a vibration module array section, a vibration array structure, a tiled vibration array, a tiled vibration array module, or a tiled vibration film.

[0202] Each of the first and second vibration generating units 1301 and 1302 in the embodiments of this specification may have a rectangular shape. For example, each of the first and second vibration generating units 1301 and 1302 may have a rectangular shape with a width of 5 cm or more. For example, each of the first and second vibration generating units 1301 and 1302 may have a square shape with dimensions of 5 cm x 5 cm or more, and the embodiments of this specification are not limited thereto.

[0203] The first and second vibration generating units 1301 and 1302 are arranged on the same plane or tiled, so that the vibration device 130 can be made to cover a large area by tiling the first and second vibration generating units 1301 and 1302, which are relatively small in size.

[0204] Each of the first and second vibration generating units 1301 and 1302 may be arranged at a fixed interval (D1) or tiled together so as a single vibrating device (or single vibrating device) that is not driven independently but is driven in the form of a complete single unit. According to the embodiments herein, the first interval (D1) between the first and second vibration generating units 1301 and 1302 with respect to a first direction (X) may be 0.1 mm or more and less than 3 cm, and the embodiments herein are not limited thereto.

[0205] According to embodiments of this specification, each of the first and second vibration generating units 1301, 1302 may be driven as a single vibration device by being arranged or tiled to have a first interval (or separation distance) (D1), thereby increasing the reproduction frequency band and sound pressure characteristics of the sound generated in conjunction with the single-body vibration of the first and second vibration generating units 1301, 1302. For example, in order to increase the reproduction frequency band of the sound generated in conjunction with the single-body vibration of the first and second vibration generating units 1301, 1302 and to increase the sound pressure characteristics of low-frequency sound, for example, below 500 Hz, the first and second vibration generating units 1301, 1302 may be arranged with a first interval (D1) of 0.1 mm or more and less than 5 mm.

[0206] According to the embodiments of this specification, when the first and second vibration generating units 1301 and 1302 are arranged with a first spacing (D1) of less than 0.1 mm or without a first spacing (D1), the reliability of the first and second vibration generating units 1301 and 1302 or the vibration device 130 may be reduced due to crack formation or damage caused by physical contact between them during the vibration of each of the first and second vibration generating units 1301 and 1302.

[0207] According to the embodiments of this specification, when the first and second vibration generating units 1301 and 1302 are arranged at a first interval (D1) of 3 cm or more, the independent vibrations of the first and second vibration generating units 1301 and 1302 may prevent them from being driven as a single vibration device. This can reduce the reproduction frequency range and sound pressure characteristics of the sound generated by the vibrations of the first and second vibration generating units 1301 and 1302. For example, when the first and second vibration generating units 1301 and 1302 are arranged at a first interval (D1) of 3 cm or more, the acoustic characteristics and sound pressure characteristics in the low-frequency range, for example, below 500 Hz, may be reduced.

[0208] According to the embodiments of this specification, when the first and second vibration generating units 1301 and 1302 are arranged at a first interval (D1) of 5 mm, the acoustic characteristics and sound pressure characteristics may be reduced in the low-frequency range, for example, below 200 Hz, because each of the first and second vibration generating units 1301 and 1302 is not driven as a single vibration device.

[0209] According to other embodiments of this specification, when the first and second vibration generating units 1301 and 1302 are arranged at a first interval (D1) of 1 mm, the vibration of the first and second vibration generating units 1301 and 1302 as a single vibrating device can increase the acoustic reproduction bandwidth and improve the sound pressure characteristics in the low-frequency range, for example, below 500 Hz. For example, when the first and second vibration generating units 1301 and 1302 are arranged at a first interval (D1) of 1 mm, the vibrating device 130 can be realized as a large-area vibrator by optimizing the spacing (or separation distance) between the first and second vibration generating units 1301 and 1302. As a result, the vibration device 130 can be driven as a large-area vibrating body by the single-body vibration of the first and second vibration generating units 1301 and 1302, thereby increasing, or potentially improving, the acoustic characteristics and sound pressure characteristics in the reproduction band and low-frequency range of the sound generated in conjunction with the large-area vibration of the vibration device 130.

[0210] Therefore, in order to achieve single-body vibration (or a single vibrating device) of the first and second vibration generating units 1301 and 1302, the first spacing (D1) between the first and second vibration generating units 1301 and 1302 can be set to 0.1 mm or more and less than 3 cm. Also, in order to increase the sound pressure characteristics of the low-frequency range acoustics while achieving single-body vibration (or a single vibrating device) of the first and second vibration generating units 1301 and 1302, the first spacing (D1) between the first and second vibration generating units 1301 and 1302 can be set to 0.1 mm or more and less than 5 mm.

[0211] Each of the first and second vibration generating units 1301 and 1302 according to the embodiments of this specification may include at least one of the vibration units 130a of the vibration device 130 described in Figures 3A to 6, and redundant explanations therein can be omitted. For example, each of the first and second vibration generating units 1301 and 1302 may include a first vibration unit and a second vibration unit. The vibration device 130 may include the first electrode unit, second electrode unit, first cover member, second cover member, first adhesive layer, and second adhesive layer described in Figures 7 and 8, and redundant explanations therein can be omitted.

[0212] According to the embodiments of this specification, each of the at least two or more vibration generating units 1301, 1302 can be realized by a single vibration device. Furthermore, according to the embodiments of this specification, each of the at least two or more vibration generating units 1301, 1302 is composed of a first vibrating unit and a second vibrating unit, so that a device with improved sound pressure characteristics and / or acoustic characteristics, including the low-frequency range, can be provided.

[0213] Figure 12 shows an apparatus according to another embodiment of this specification.

[0214] Referring to Figure 12, the vibration device 130 according to other embodiments of this specification may include at least two or more vibration generating units 1301, 1302, 1303, 1304.

[0215] The vibration device 130 according to the embodiments of this specification can vibrate the vibrating member 100 by vibrating in the thickness direction (Z) by alternately contracting and expanding due to the inverse piezoelectric effect. For example, the vibration device 130 according to the embodiments of this specification can directly vibrate the vibrating member 100 by vibrating in the thickness direction (Z) by alternately contracting and expanding due to the inverse piezoelectric effect. For example, the vibration device 130 may be, but is not limited to, a vibration film, a displacement generator, a displacement film, an acoustic generator, a vibration array, a vibration array section, a vibration structure array section, a vibration array structure, a tiling vibration array, a tiling vibration array module, or a tiling vibration film. The vibration device 130 may include at least two or more vibration generating sections 1301, 1302, 1303, 1304 arranged at regular intervals or tiled together. At least two or more vibration generating units 1301, 1302, 1303, and 1304 can vibrate by repeatedly contracting and expanding alternately due to the piezoelectric effect (or piezoelectric properties). For example, at least two or more vibration generating units 1301, 1302, 1303, and 1304 may be, but are not limited to, a vibration array, vibration generating array, segmented vibration array, partial vibration array, segmented vibration structure, partial vibration structure, or individual vibration structure.

[0216] According to other embodiments herein, at least two or more vibration generating units 1301, 1302, 1303, 1304 may be arranged separately from each other along a first direction (X) (or transverse direction) and a second direction (Y) (or longitudinal direction) intersecting the first direction (X). At least two or more vibration generating units 1301, 1302, 1303, 1304 may be arranged electrically separately from each other along a first direction (X) (or transverse direction) and a second direction (Y) (or longitudinal direction) intersecting the first direction (X). For example, by arranging at least two or more vibration generating units 1301, 1302, 1303, 1304 on the same plane in an i × j shape or by tiling, the vibration device 130 can be made larger in area by tiling at least two or more vibration generating units 1301, 1302, 1303, 1304 having relatively small sizes. For example, i is a natural number of 2 or more, representing the number of vibration generating units arranged along the first direction (X), and j is a natural number of 2 or more, which is the same as or different from i, representing the number of vibration generating units arranged along the second direction (Y). For example, at least two or more vibration generating units 1301, 1302, 1303, 1304 can be arranged in a 2x2 configuration or tiled, and the embodiments herein are not limited thereto. In the following description, it is assumed that the vibration device 130 includes first to fourth vibration generating units 1301, 1302, 1303, 1304.

[0217] According to the embodiments herein, the first and second vibration generating units 1301 and 1302 may be separated from each other along a first direction (X). The third and fourth vibration generating units 1303 and 1304 may be separated from each other along a second direction (Y) while being separated from each other along a first direction (X). The first and third vibration generating units 1301 and 1303 may face each other and be separated from each other along a second direction (Y). The second and fourth vibration generating units 1302 and 1304 may face each other and be separated from each other along a second direction (Y).

[0218] Referring to Figures 7, 8, and 12, the first to fourth vibration generating units 1301, 1302, 1303, and 1304 can be positioned between the first cover member 130d and the second cover member 130e. For example, each of the first cover member 130d and the second cover member 130e can drive the first to fourth vibration generating units 1301, 1302, 1303, and 1304 as a single vibrator (or single vibrator) by connecting or commonly supporting them. For example, the first to fourth vibration generating units 1301, 1302, 1303, and 1304 can be driven as a single vibrator (or single vibrator) by tiling them at regular intervals on the first and second cover members 130d and 130e.

[0219] As described with reference to Figure 11, the first to fourth vibration generating units 1301, 1302, 1303, and 1304 may be arranged (or tiled) at intervals of 0.1 mm or more and less than 3 cm along the first direction (X) and the second direction (Y), respectively, for complete single-body vibration or large-area vibration, for example, at intervals of 0.1 mm or more and less than 5 mm.

[0220] Each of the first to fourth vibration generating units 1301, 1302, 1303, and 1304 according to the embodiments of this specification may include at least one of the vibration units 130a of the vibration device 130 described in Figures 3A to 6, and redundant explanations therein can be omitted. For example, each of the first to fourth vibration generating units 1301, 1302, 1303, and 1304 may include a first vibration unit and a second vibration unit. Each of the first to fourth vibration generating units 1301, 1302, 1303, and 1304 may include a first electrode unit and a second electrode unit as described in Figures 7 and 8, and the vibration device 130 may include a first cover member, a second cover member, a first adhesive layer, and a second adhesive layer, and redundant explanations therein can be omitted.

[0221] According to the embodiments of this specification, each of the first to fourth vibration generating units 1301, 1302, 1303, and 1304 may include any of the vibration units 130a of the vibration device 130 described in Figures 3A to 6, or may include different vibration units 130a from each other.

[0222] According to the embodiments herein, each of at least two or more vibration generating units 1301, 1302, 1303, and 1304 can be realized by a single vibration device. Furthermore, according to the embodiments herein, each of at least two or more vibration generating units 1301, 1302, 1303, and 1304 is composed of a first vibrating unit and a second vibrating unit, so that a device with improved sound pressure characteristics and / or acoustic characteristics, including the low-frequency range, can be provided.

[0223] Figure 13 shows a vibrating device according to another embodiment of this specification. Figure 13 is another cross-sectional view along the line A-A' shown in Figure 1.

[0224] Referring to Figure 13, the vibration device 130 according to other embodiments of this specification may include at least two or more vibration generators 134, 135.

[0225] A vibration device containing a single vibration generator has the problem of not being able to output sufficient sound. For example, when a vibration device containing a single vibration generator is configured in a display device such as a TV, it is difficult to ensure (or generate) sufficient sound. When a vibration device realized with two vibration generators is applied to the device, the contact area between the vibrating member (or object to be vibrated) and the vibration device can be increased. However, with an increased contact area, when attaching a vibration device to the back of a display panel, for example, it is difficult to attach it to the back of the display panel without air bubbles. For example, if the display panel is an illuminating display panel, it is difficult to attach the vibration device to the sealing substrate without air bubbles. Furthermore, a vibration device realized by attaching two vibration generators placed side by side has the problem of divided vibration (or biased vibration), where the vibrations between adjacent vibration generators are different from each other, resulting in different vibrations. This leads to a decrease in the flatness of the acoustic characteristics. Divided vibration (or biased vibration) increases as the contact area of ​​the vibration device increases.

[0226] The vibration device 130 according to the embodiments of this specification may include at least two or more vibration generators 134, 135. For example, the vibration device 130 according to the embodiments of this specification may include at least two or more vibration generators 134, 135 that are superimposed on each other. At least two or more vibration generators 134, 134 can vibrate in the same direction. For example, the vibration device 130 may include at least two or more vibration generators 134, 135 that are superimposed or stacked so that they are displaced (or vibrated or driven) in the same direction to each other. For example, the vibration device 130 may include at least two or more vibration generators 134, 135 that are superimposed or stacked so that they have the same driving direction (or vibration direction or displacement direction) to each other.

[0227] At least two or more vibration generators 134, 135 can overlap or stack on top of each other so that they are displaced (or driven or vibrated) in the same direction. For example, each of the at least two or more vibration generators 134, 135 can increase or maximize the displacement (or bending force) or amplitude displacement by contracting or expanding in the same driving direction (or displacement direction or vibration direction) in response to a vibration drive signal while overlapping or stacked with each other. This allows the at least two or more vibration generators 134, 135 to increase (or maximize) the displacement (or bending force) or amplitude displacement of the display panel or vibrating member 100, thereby improving the acoustic characteristics and / or sound pressure characteristics, including the mid-to-low frequency range, generated by the vibration of the display panel or vibrating member 100. For example, the driving force of the at least two or more vibration generators 134, 135 can be increased or maximized by implementing them to overlap or stack on top of each other so that they have the same driving direction. This makes it possible to improve the acoustic and / or sound pressure characteristics in the mid-to-low frequency range generated in the vibrating member 100 by the vibration of at least two or more vibration generators 134, 135. For example, the mid-to-low frequency range may be 200 Hz to 1 kHz, and the embodiments herein are not limited thereto.

[0228] Each of the at least two vibration generators 134, 135 according to the embodiments of this specification may include at least one of the vibrating parts 130a of the vibration device 130 described in Figures 3A to 6, and redundant explanations therein can be omitted. For example, each of the at least two vibration generators 134, 135 may include a first vibrating part and a second vibrating part. Each of the at least two vibration generators 134, 135 may include a first electrode part and a second electrode part, a first cover member, a second cover member, a first adhesive layer, and a second adhesive layer as described in Figures 7 and 8, and redundant explanations therein can be omitted.

[0229] Each of the at least two vibration generators 134, 135 may include at least two vibration generating units. For example, each of the at least two vibration generators 134, 135 may include the first and first vibration generating units 1301, 1302 described in Figure 11, or the first to fourth vibration generating units 1301, 1302, 1303, 1304 described in Figure 12, and redundant explanations therein can be omitted.

[0230] When a vibration drive signal (or voice signal) is applied to each of the two or more vibration generators 134, 135, the inverse piezoelectric effect of the first and second vibrating parts causes them to alternately contract and expand, resulting in a bending phenomenon where the bending direction alternates, causing them to displace (or vibrate or drive) each other in the same direction, thereby increasing or maximizing the displacement (or bending force) or amplitude displacement of the vibration device 130 and / or the vibrating member 100 (or display panel).

[0231] Of the at least two or more vibration generators 134, 135, the first vibration generator 134 positioned on the vibrating member 100 may be one main vibration generator. For example, the remaining second vibration generator 135 of the at least two or more vibration generators 134, 135 may be at least one auxiliary vibration generator that has the same structure as the first vibration generator 134 but is laminated on the first vibration generator 134. The second vibration generator 135 may have the same structure as the first vibration generator 134, and the embodiments herein are not limited thereto. For example, the first vibration generator 134 may be, and is not limited thereto, a first vibration array, a first displacement generator, a first displacement film, a first acoustic generator, a first vibration array, a first vibration array section, a first vibration structure array section, a first vibration array structure, a first tiling vibration array, a first tiling vibration array module, or a first tiling vibration film. For example, the second vibration generator 135 may be, but is not limited to, a second vibration array, a second displacement generator, a second displacement film, a second sound generator, a second vibration array, a second vibration array section, a second vibration structure array section, a second vibration array structure, a second tiling vibration array, a second tiling vibration array module, or a second tiling vibration film.

[0232] The vibration device 130 according to the embodiments of this specification may further include an adhesive member 136 (or a third connecting member) disposed between at least two or more vibration generators 134, 135.

[0233] The adhesive member 136 according to the embodiments of this specification may be placed between at least two or more vibration generators 134, 135. For example, the adhesive member 136 may be made of a material that includes an adhesive layer with excellent adhesion or bonding strength to each of the at least two or more vibration generators 134, 135. For example, the adhesive member 136 may include foam pads, double-sided tape, or adhesives, and the embodiments of this specification are not limited thereto. For example, the adhesive layer of the adhesive member 136 may include epoxy, acrylic, silicone, or urethane, and the embodiments of this specification are not limited thereto. For example, the adhesive layer of the adhesive member 136 may include a urethane-based material (or material) that has relatively more flexible properties than acrylic-based materials. This minimizes vibration loss within the vibration device 130 due to interference of displacement between at least two or more vibration generators 134, 135, or allows each of the at least two or more vibration generators 134, 135 to be freely displaced (or vibrate or driven).

[0234] At least two or more vibration generators 134, 135 according to the embodiments of this specification can be integrated into a single structure (or component) by a lamination process using an adhesive member 136.

[0235] The apparatus according to the embodiments of this specification may further include a connecting member 150 (or a first connecting member) disposed between the vibrating member 100 and the vibrating device 130.

[0236] The connecting member 150 is positioned between the vibrating member 100 and the vibrating device 130, thereby connecting or coupling the vibrating device 130 to the back of the display panel or the vibrating member 100. For example, the vibrating device 130 may be supported or positioned on the back of the vibrating member 100 by being connected or coupled to the back of the display panel or the vibrating member 100 via the connecting member 150.

[0237] The connecting member 150 according to the embodiments of this specification may be made of a material including an adhesive layer having a relatively strong adhesion or bonding force to the back surface of the display panel or vibrating member 100 and to the vibrating device 130, respectively. For example, the connecting member 150 may include a foam pad, double-sided tape, or adhesive, and the embodiments of this specification are not limited thereto. For example, the adhesive layer of the connecting member 150 may include epoxy, acrylic, silicone, or urethane, and the embodiments of this specification are not limited thereto. For example, the adhesive layer of the connecting member 150 may differ from, or be different from, the adhesive layer of the adhesive member 136. For example, the adhesive layer of the connecting member 150 may include an acrylic-based material (or material) that has a relatively strong adhesive force and high hardness compared to urethane-based materials, so that the vibrations of the vibrating device 130 can be effectively transmitted to the display panel or vibrating member 100.

[0238] The adhesive layer of the connecting member 150 may further contain additives such as tackifiers, wax components, or antioxidants. These additives can prevent the connecting member 150 from separating (or peeling off) from the display panel or vibrating member 100 due to vibrations from the vibrating device 130. For example, the tackifier may be a rosin derivative, and the wax component may be paraffin wax. For example, the antioxidant may be a phenolic antioxidant such as a thioester, and the examples herein are not limited thereto.

[0239] Other embodiments of the connecting member 150 according to this specification may further include a hollow portion provided between the display panel or vibrating member 100 and the vibrating device 130. The hollow portion of the connecting member 150 can provide an air gap between the display panel or vibrating member 100 and the vibrating device 130. The air gap minimizes vibration loss by the connecting member 150 by preventing sound waves (or sound pressure) from the vibration of the vibrating device 130 from being dispersed by the connecting member 150 and concentrating them on the display panel or vibrating member 100, thereby increasing the acoustic and / or sound pressure characteristics of the sound generated by the vibration of the display panel or vibrating member 100.

[0240] The apparatus according to the embodiments of this specification may further include a support member 300 and a middle frame 400 positioned on the back of the vibrating member 100. The description of the support member 300 and the middle frame 400 is the same as or similar to that described in Figures 1 and 2, so redundant descriptions therein can be omitted.

[0241] The vibrating device 130 according to the embodiments of this specification may further include a plate.

[0242] According to embodiments of this specification, the plate can be connected to or bonded to the back surface of the vibrating member 100. For example, if the vibrating member 100 is a light-emitting display panel, the plate may be positioned on the back surface of the sealing portion of the light-emitting display panel. The plate may be configured to be positioned on the back surface of the sealing portion and bonded to it. The plate can dissipate heat generated from the display panel. For example, the plate can be described as a heat dissipation member, a heat dissipation plate, or a heat sink, and is not limited to these terms.

[0243] According to embodiments of this specification, a plate can be positioned on the back of the vibrating member 100 or can reinforce the mass of a suspended vibrating device 130. This allows the plate to reduce the resonant frequency of the vibrating device 130 due to the increase in its mass. Thus, the plate can increase the low-frequency acoustic characteristics and low-frequency sound pressure characteristics of the sound generated in conjunction with the vibration of the vibrating device 130, and improve the flatness of the sound pressure characteristics. Here, the flatness of the acoustic characteristics may be the magnitude of the deviation between the highest and lowest sound pressure. For example, the plate can be described as a weight member, mass member, or acoustic flattening member, and is not limited to these terms.

[0244] The plate may have the same shape and size as the vibrating member 100 or the display panel, or the same shape and size as the vibrating device 130. In other embodiments of this specification, the plate may have a different size from the vibrating member 100 or the display panel. For example, the plate may be smaller than the vibrating member 100 or the display panel. In other embodiments of this specification, the plate may have a different size from the vibrating device 130. For example, the plate may be larger or smaller than the vibrating device 130. The vibrating device 130 may be the same size as or smaller than the vibrating member 100 or the display panel.

[0245] The plates according to the embodiments of this specification may be made of a metallic material. For example, the plates may be made of one or more materials from stainless steel, aluminum (Al), magnesium (Mg), magnesium (Mg) alloy, magnesium-lithium (Mg-Li) alloy, and aluminum (Al) alloy, and the embodiments of this specification are not limited thereto.

[0246] According to the embodiments herein, the displacement (or bending force) and amplitude displacement (or vibration amplitude) of the vibrating member 100 or display panel on which the plate is placed may decrease as the plate thickness increases due to the rigidity of the plate. This may reduce the low-frequency acoustic and sound pressure characteristics of the sound generated by the displacement (or vibration) of the vibrating member 100 or display panel.

[0247] The plate according to the embodiments of this specification is coupled to or may be coupled to the back of the vibrating member 100 or the display panel via a connecting member (or a fifth connecting member). The connecting member may be positioned between the vibrating member 100 and the plate.

[0248] The connecting member (or fifth connecting member) according to the embodiments of this specification may include an adhesive layer with excellent adhesion or bonding strength to the back surface of the vibrating member 100 or the display panel and to the vibrating device 130, respectively. For example, the connecting member may include a foam pad, double-sided tape, or adhesive. For example, the adhesive layer of the connecting member may include epoxy, acrylic, silicone, or urethane, and the embodiments of this specification are not limited thereto. For example, the adhesive layer of the connecting member may be the same as the adhesive layer of the connecting member 150, and the embodiments of this specification are not limited thereto. For example, the adhesive layer of the connecting member may include an acrylic-based material (or material) that has relatively strong adhesion and high hardness compared to urethane-based materials, so that the vibrations of the vibrating device 130 are effectively transmitted to the vibrating member 100 or the display panel. In other embodiments of this specification, the adhesive layer of the connecting member may be configured differently from the adhesive layer of the connecting member 150.

[0249] The plate according to the embodiments of this specification may be integrated with the vibrator 130 or included in the configuration of the vibrator 130. For example, the plate and the vibrator 130 may consist of a single structure or a single component (or module) comprising a single body. This may facilitate the assembly process between the vibrator 100 or the display panel and the vibrator 130 by unifying (modularizing) the components between the plate and the vibrator 130 when the plate is positioned between the back of the vibrator 100 or the display panel and the vibrator 130.

[0250] In other embodiments of this specification, the plate and vibrator 130 can be configured as a diaphragm when the plate and vibrator 130 are composed of a single structure or a single part (or module) consisting of a single fuselage. The plate and vibrator 130 can be positioned on the non-visible panel. The plate and vibrator 130 can be coupled to or connected to each other via a connecting member 150. For example, the plate can include one or more of the following: metal, wood, rubber, plastic, glass, cloth, fiber, paper, carbon, mirror, leather, automotive interior materials, building ceilings, and aircraft interior materials, and the embodiments of this specification are not limited thereto. Thus, the vibrator 130 can vibrate the non-visible panel to produce sound. In other embodiments of this specification, the plate and vibrator 130 can be configured as a diaphragm when the plate and vibrator 130 are composed of a single structure or a single part (or module) consisting of a single fuselage. For example, in a plate and a module (or structure) of the vibrator 130, the plate may consist of one or more single nonmetallic or composite nonmetallic materials, including wood, rubber, plastic, glass, cloth, paper, fiber, carbon, mirror, and leather, and the embodiments herein are not limited thereto.

[0251] Plates according to other embodiments of this specification may include a plurality of openings. The plurality of openings may be configured to have a fixed size and fixed spacing. For example, the plurality of openings may be formed along a first direction (X) and a second direction (Y) to have a fixed size and fixed spacing. Each of the plurality of openings can minimize vibration loss by the plate and increase the sound pressure characteristics of the sound generated by the vibration of the vibrating member 100 by ensuring that the sound waves (or sound pressure) from the vibration of the vibrating device 130 are not dispersed by the plate but concentrated on the vibrating member 100. For example, a plate including a plurality of openings may have a mesh shape. For example, a plate including a plurality of openings may be a mesh plate.

[0252] The apparatus according to the embodiment of this specification is configured with at least two or more vibration generators 134, 135, and the vibration of at least two or more vibration generators 134, 135 can improve the acoustic characteristics in the mid-to-low frequency range and / or the sound pressure characteristics of the sound generated from the vibrating member 100.

[0253] Furthermore, the apparatus according to the embodiment of this specification further includes a plate positioned on the back of the vibrating device 130, thereby reducing the resonant frequency of the vibrating device 130. As a result, the apparatus according to the embodiment of this specification can increase the low-frequency acoustic characteristics and / or low-frequency sound pressure characteristics generated by the vibration of the vibrating member 100 or the display panel linked to the vibration of the vibrating device 130, and improve the flatness of the sound pressure characteristics.

[0254] Furthermore, since the apparatus according to the embodiment of this specification has at least two or more vibration generators 134, 135, each composed of a first vibration section and a second vibration section, it is possible to provide an apparatus with improved sound pressure characteristics and / or acoustic characteristics, including the low-frequency range.

[0255] Figure 14 shows an apparatus according to another embodiment of this specification. Figure 15 is a cross-sectional view along the line C-C' shown in Figure 14.

[0256] Referring to Figures 14 and 15, in apparatus according to other embodiments of this specification, the rear (or back) surface of the vibrating member 100 or the display panel may include a first region (or first back region) (A1) and a second region (or second back region) (A2). For example, on the back surface of the vibrating member 100 or the display panel, the first region (A1) may be the left back region, and the second region (A2) may be the right back region. The first and second regions (A1, A2) may be symmetrical with respect to a first direction (X) around the midline (CL) of the vibrating member 100, and the embodiments of this specification are not limited thereto. For example, each of the first and second regions (A1, A2) may overlap with the display region of the display panel if the vibrating member 100 is a display panel.

[0257] Other embodiments of the vibration device 130 described herein may include a first vibration device 137 and a second vibration device 138 located on the back of the vibration member 100 or the display panel. For example, the first vibration device 137 may be, but is not limited to, a first vibration generator, a first displacement device, a first acoustic device, or a first acoustic generator. For example, the second vibration device 138 may be, but is not limited to, a second vibration generator, a second displacement device, a second acoustic device, or a second acoustic generator.

[0258] The first vibration device 137 can be disposed in the first region (A1) of the vibration member 100 or the display panel. For example, the first vibration device 137 can be disposed at the center within the first region (A1) of the vibration member 100 or the display panel with respect to the first direction (X). As another example, the first vibration device 137 can be disposed so as to be biased toward the center or the edge portion within the first region (A1) of the vibration member 100 or the display panel with respect to the first direction (X). The first vibration device 137 according to the embodiments of the present specification can generate a first vibration sound or a first haptic feedback in the first region (A1) of the vibration member 100 or the display panel by vibrating the first region (A1) of the vibration member 100 or the display panel. For example, the first vibration device 137 according to the embodiments of the present specification can generate a first vibration sound or a first haptic feedback in the first region (A1) of the vibration member 100 or the display panel by directly vibrating the first region (A1) of the vibration member 100 or the display panel. For example, the first vibration sound can be a sound on the left side. The size of the first vibration device 137 according to the embodiments of the present specification can be less than or equal to half the size of the first region (A1) or greater than or equal to half the size depending on the characteristics of the first vibration sound or the acoustic characteristics required for the device. As another embodiment of the present specification, the size of the first vibration device 137 can be the size corresponding to the first region (A1) of the vibration member 100 or the display panel. For example, the size of the first vibration device 137 can be the same as the size of the first region (A1) of the vibration member 100 or the display panel or smaller than the size of the first region (A1).

[0259] The second vibration device 138 may be positioned in the second region (A2) of the vibrating member 100 or the display panel. For example, the second vibration device 138 may be positioned in the central part of the second region (A2) of the vibrating member 100 or the display panel with respect to the first direction (X). For example, the second vibration device 138 may be positioned so as to be off-center or towards the edge of the second region (A2) of the vibrating member 100 or the display panel with respect to the first direction (X). The second vibration device 138 according to the embodiments herein can generate a second vibroacoustic or second haptic feedback in the second region (A2) of the vibrating member 100 or the display panel by vibrating the second region (A2) of the vibrating member 100 or the display panel. For example, the second vibration device 138 according to the embodiment of this specification can generate a second vibratory acoustic or second haptic feedback in the second region (A2) of the vibrating member 100 or the display panel by directly vibrating the second region (A2) of the display panel. For example, the second vibratory acoustic may be the right-hand acoustic. The size of the second vibration device 138 according to the embodiment of this specification can be half or less the size of the second region (A2), or more than half the size, depending on the characteristics of the second vibratory acoustic or the acoustic characteristics required of the device. In other embodiments of this specification, the size of the second vibration device 138 can be the size corresponding to the second region (A2) of the vibrating member 100 or the display panel. For example, the size of the second vibration device 138 can be the same size as the second region (A2) of the vibrating member 100 or the display panel, or smaller than the second region (A2). Therefore, the first and second vibrators 137 and 138 may be the same size or different in size from each other, depending on the acoustic characteristics of the left and right sides of the device and / or the acoustic characteristics of the device. The first and second vibrators 137 and 138 may be arranged in a symmetrical or asymmetrical configuration around the midline (CL) of the vibrating member 100 or the display panel.

[0260] Since each of the first vibration device 137 and the second vibration device 138 includes one or more of the vibration parts 130a of the vibration device 130 described in FIGS. 3A to 6, duplicate explanations thereof can be omitted.

[0261] According to the embodiments of this specification, each of the first vibration device 137 and the second vibration device 138 can include one or more of the vibration parts 130a of the vibration device 130 described in at least one of FIGS. 3A to 4D. When configured in this way, each of the first vibration device 137 and the second vibration device 138 can realize an acoustic including a high-frequency band and / or a low-frequency band depending on the position of the vibration member 100 or the display panel.

[0262] According to the embodiments of this specification, each of the first vibration device 137 and the second vibration device 138 can include one or more of the vibration parts 130a of the vibration device 130 described in at least one of FIGS. 5B and 5D. When configured in this way, each of the first vibration device 137 and the second vibration device 138 can realize an acoustic from a low-frequency band to a high-frequency band as going from the center to the edge portion of the vibration member 100 or the display panel.

[0263] According to the embodiments of this specification, each of the first vibration device 137 and the second vibration device 138 can include one or more of the vibration parts 130a of the vibration device 130 described in FIG. 5C. When configured in this way, each of the first vibration device 137 and the second vibration device 138 can realize an acoustic from a high-frequency band to a low-frequency band as going from the center to the edge portion of the vibration member 100 or the display panel. For example, when each of the first vibration device 137 and the second vibration device 138 is configured by the vibration device 130 described in at least one of FIGS. 3A to 5D, the vibration device 130 described in FIG. 6 can be applied together.

[0264] The connecting member 150 according to the embodiments of this specification may be positioned between each of the first vibrator 137 and the second vibrator 138 and the back of the vibrator 100 or the display panel. For example, each of the first vibrator 137 and the second vibrator 138 may be positioned on the back of the vibrator 100 or the display panel via the connecting member 150. The connecting member 150 is identical or substantially the same as the connecting member 150 described in Figure 2, so a redundant explanation of it can be omitted.

[0265] Therefore, the apparatus according to other embodiments of this specification can provide sound to the user by outputting sound, including left-side sound and right-side sound, to the front of the vibrating member 100 or display panel using the first vibrating device 137 and the second vibrating device 138.

[0266] Figure 16 is a perspective view showing an apparatus according to another embodiment of this specification. Figure 17 is a diagram showing a vibrating member and a vibrating device according to another embodiment of this specification.

[0267] Referring to Figures 16 and 17, the apparatus according to other embodiments of this specification may include a vibrating member 110 and a housing 15. The apparatus according to other embodiments of this specification may be an apparatus applicable to a soundbar. For example, the apparatus according to other embodiments of this specification may be a soundbar or an acoustic device, and is not limited to this term.

[0268] The vibrating member 110 may be configured to be identical or substantially the same as the vibrating member 100 shown in any one of Figures 2, 8, and 13.

[0269] The housing 15 may be positioned behind the vibrating member 110 so as to cover the back of the vibrating member 110 and the vibration generating device 130. For example, the housing 15 may have a housing space for accommodating the vibration generating device 130 and may include a box shape with one side (or part of it) open. For example, the vibration generating device 130 may be a vibrating device, and is not limited to this term.

[0270] The housing 15 in the embodiments of this specification may include one or more materials, including metallic materials and non-metallic materials (or composite non-metallic materials), and the embodiments of this specification are not limited thereto. For example, the housing 15 may include one or more materials, including metallic materials, plastics, and wood, and the embodiments of this specification are not limited thereto. For example, the housing 15 may be described by terms such as case, outer case, case member, housing member, cabinet, enclosure, sealing member, sealing cap, sealed box, or soundbox, and is not limited thereto. For example, the housing space of the housing 15 may be described by terms such as gap space, air gap, vibration space, acoustic space, resonant chamber, or sealed space, and is not limited thereto.

[0271] The housing 15 according to the embodiment of this specification can maintain a constant impedance component due to the air acting on the vibrating member 110 when the vibrating member 110 is vibrating. For example, the air surrounding the vibrating member 110 resists the vibration of the vibrating member 110 and acts as an impedance component having different resistance and reactance components depending on the frequency. As a result, the housing 15, by forming a sealed space surrounding the vibration generator 130, maintains a constant impedance component (or air impedance or elastic impedance) acting on the vibrating member 110 due to the air, thereby improving the acoustic characteristics and / or sound pressure characteristics in the low-frequency range and improving the sound quality of the high-frequency range sound generated by the vibration of the vibrating member 110.

[0272] The connecting member may be positioned between the back surface of the vibrating member 110 and the housing 15. The side of the housing 15 may be connected to or coupled to the back surface of the vibrating member 110 via the connecting member. For example, the side of the housing 15 may be connected to or coupled to the edge portion of the back surface of the vibrating member 110 via the connecting member.

[0273] According to embodiments of this specification, the vibrating member 110 may include multiple regions. The vibrating member 110 may include first to nth (n is a natural number greater than or equal to 2) regions. The vibrating member 110 may include a vibration generator 130 located on its rear. The vibration generator 130 may vibrate the vibrating member 110. The vibration generator 130 may include first to nth vibrating devices (or vibrating elements) connected to the first to nth regions of the vibrating member 110. According to embodiments of this specification, the sound output from one or more regions among the first to nth regions may have a different frequency range than the sound output from the remaining regions (or one or more other regions among the first to nth regions). Each of the first to nth vibrating devices according to embodiments of this specification may include at least one of the vibrating parts 130a of the vibrating device 130 described in Figures 3A to 6, and redundant explanations thereof can be omitted. For example, each of the first to nth vibrating devices may include a first vibrating part and a second vibrating part. Each of the first to nth vibration devices may include the first electrode section, second electrode section, first cover member, second cover member, first adhesive layer, and second adhesive layer as described in Figures 7 and 8, and redundant explanations of these can be omitted.

[0274] According to the embodiments herein, the vibration generator 130 may include a plurality of vibration devices (or vibration elements). The vibration generator 130 may include first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6, which are shown as examples, and may include six or more vibration devices. For example, the vibration generator 130 may include first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6 connected to or tiled on the back of the vibrating member 110 so as to be at regular intervals along a first direction (X). For example, each of the first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6 may be a vibration generating unit or a vibrating unit, and the embodiments herein are not limited to this terminology.

[0275] Each of the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 may have a square in which the horizontal (L1) and vertical (L2) dimensions are the same or substantially the same, and the embodiments herein are not limited thereto. For example, each of the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 may have a rectangle in which the horizontal (L1) dimension is relatively longer than the vertical (L2) dimension.

[0276] The sound generated by the vibrating member 110, which vibrates due to the vibration of each of the first to sixth vibrating devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6, may have its reproduction bandwidth and sound pressure characteristics reduced by reinforcing interference and / or canceling interference and standing waves generated by reflected waves reflected by the connecting member. With respect to a first direction (X), the first interval (or gap or distance) (D1) between adjacent vibrating devices among the first to sixth vibrating devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 may be 3 mm or more and 5 mm or less, and the embodiments herein are not limited thereto. This makes it possible to prevent or minimize the reduction in the reproduction bandwidth and / or sound pressure characteristics of the sound due to the influence of reflected waves.

[0277] According to the embodiments of this specification, when the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 are arranged with a first spacing (D1) of less than 3 mm or without a first spacing (D1), the reliability of each of the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 may be reduced due to crack formation or breakage caused by physical contact between them during the vibration of each of the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6.

[0278] According to the embodiments of this specification, when the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 are arranged at a first interval (D1) greater than 5 mm, the acoustic characteristics and / or sound pressure characteristics of each of the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 may be reduced due to the influence of reflected waves. For example, when the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 are arranged at a first interval (D1) greater than 5 mm, the acoustic characteristics and sound pressure characteristics in the low-frequency range, for example, below 500 Hz, may be reduced.

[0279] According to the embodiments of this specification, when the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 are arranged at a first interval (D1) of 3 mm to 5 mm, the reinforcing interference and / or canceling interference and the formation of standing waves due to reflected waves generated by the vibrations of each of the first to sixth vibrators 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 are reduced or minimized, thereby increasing the reproducible frequency band of the sound and improving the sound pressure characteristics in the low-frequency range, for example, below 500 Hz.

[0280] According to embodiments herein, the second spacing (D2) may be the spacing (or gap or distance) between the end (or edge) of the vibrating member 110 (e.g., E1 or E2) closest to the end or edge of the vibrating member 110 and the vibrating device (e.g., 130-1 or 130-6). With respect to the first direction (X), the second spacing (D2) may be smaller than the transverse length (L1) of one (or each) of the vibrating devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6, and larger than the first spacing (D1).

[0281] According to the embodiments of the present specification, based on the second direction (Y), the third interval (or gap or distance) (D3) between each of the first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6 and each end of the vibration member 110 may be smaller than the longitudinal length (L2) of one (or each) of the vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6 (for example, the first vibration device 130-1) and may be larger than the first interval (D1). For example, when the second interval (D2) is relatively larger than the transverse length (L1) of one (or each) of the vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6 (for example, the first vibration device 130-1) and the third interval (D3) is relatively larger than the longitudinal length (L2) of one vibration device, for example, the first vibration device 130-1, the vibration regions of the first vibration device 130-1 and the sixth vibration device 130-6 increase relatively, whereby the uniformity of the acoustic characteristics and / or sound pressure characteristics may be degraded. Therefore, in order to realize uniform acoustic characteristics and / or sound pressure characteristics due to the vibrations of each of the first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6, the second interval (D2) may be smaller than the transverse length (L1) of one (or each) of the vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, 130-6 (for example, the first vibration device 130-1) and may be larger than the first interval (D1), and the third interval (D3) may be smaller than the longitudinal length (L2) of one vibration device, for example, the first vibration device 130-1 and may be larger than the first interval (D1).

[0282] Each of the first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 can output sound generated by the vibration of the vibrating member 110 by vibrating the vibrating member 110 in response to a vibration drive signal supplied from the sound processing circuit. For example, each of the first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 can vibrate the vibrating member 110 in response to a vibration drive signal and output sound in the same frequency range, and the embodiments of this specification are not limited thereto. For example, one or more of the first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6 can vibrate the vibrating member 110 in response to a vibration drive signal and output sound in different frequency ranges.

[0283] In other embodiments of this specification, the apparatus can improve the reproduction frequency band and / or sound pressure characteristics of the sound by vibrating the vibrating member 110 with the vibration of first to sixth vibrating devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6, which are connected to the back of the vibrating member 110 with a spacing (D1) to account for the effects of reflected waves, and thereby outputting sound.

[0284] Figures 18A to 18C show apparatus according to other embodiments of this specification.

[0285] Referring to Figures 18A to 18C, the apparatus according to other embodiments of this specification may include a vibrating member 110 and a vibration generating device 130.

[0286] The vibration generator 130 may include at least two or more vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6. For example, the vibration generator 130 may include the first to nth (where n is a natural number greater than or equal to 2) vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6. For example, the vibration generator 130 may include the first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6. For example, the vibration generator 130 may be a vibration device and is not limited to this term.

[0287] If the object (or user) receiving the sound source is located in the center of the device or soundbar, in order to transmit the sound source to the outer casing (or one or each of the ends) that is farther from the object, the first to nth vibrating devices positioned near the outer casing can be arranged such that the fraction (or magnitude) of the first vibrating part 131, which has high acoustics in the low-frequency range, is higher (or greater) than the fraction (or magnitude) of the second vibrating part 132. This makes it possible to provide the object (or user) with a sound source or sound with a uniform frequency range. For example, because low-frequency ranges have short wavelengths and long wavelengths, the sound source or sound can be transmitted (or moved) over long distances from the object.

[0288] According to embodiments of this specification, each of the first to nth vibrators positioned close to the object of the device (or the user listening to the sound of the device) may be configured such that the size of the second vibrating section 132 is larger than the size of the first vibrating section 131, and each of the first to nth vibrators positioned far from the object of the device may be configured such that the size of the first vibrating section 131 is larger than the size of the second vibrating section 132. According to other embodiments of this specification, each of the first to nth vibrators positioned close to the object of the device may be configured such that the size of the second vibrating section 132 of each of the first to nth vibrators positioned close to the object is larger than the size of one of the first vibrating sections 131 of the first to nth vibrators positioned close to the object. Furthermore, each of the first to nth vibrators positioned close to the object of the device may be configured such that the size of the first vibrating section 131 of each of the first to nth vibrators positioned close to the object is larger than the size of one of the second vibrating sections 132 of the first to nth vibrators positioned close to the object.

[0289] Referring to Figure 18A, the first vibrator 130-1 and the sixth vibrator 130-6 may be configured such that the first vibrating portion 131 has a larger fraction (or magnitude) than the second vibrating portion 132. When the object that hears the sound of the vibration generator 130 is located at the center of the vibrating member 110, the center of the vibrating member 110 may be configured such that the magnitude of the second vibrating portion 132 of each of the first to n vibrating devices is greater than the magnitude of the first vibrating portion 131, and the magnitude of the first vibrating portion 131 may be greater than the magnitude of the second vibrating portion 132 as the object is further away. According to other embodiments of this specification, if the object listening to the sound of the vibration generator 130 is located at the center of the vibration member 110, the center of the vibration member 110 may be configured such that the size of the second vibrating portion 132 of each of the first to n vibrating devices located closer to the center (than the periphery) of the vibration member 110 is greater than the size of the first vibrating portion 131 of each of the first to n vibrating devices, and the size of the first vibrating portion 131 may be configured to be greater than the size of the second vibrating portion 132 as it moves further away from the object. For example, assuming the object (or the user listening to the sound of the device) is located at the center, the first vibration device 130-1 and the sixth vibration device 130-6, which are farther from the object, may be configured such that the fraction (or size) of the first vibrating portion 131 is greater than the fraction (or size) of the second vibrating portion 132. The second vibrator 130-2 and the fifth vibrator 130-5 may be configured such that the first vibrating section 131 has a larger fraction (or magnitude) than the second vibrating section 132. For example, the second vibrator 130-2 and the fifth vibrator 130-5 may be configured so that the fraction (or magnitude) of the first vibrating section 131 of each of the second vibrator 130-2 and the fifth vibrator 130-5 is smaller than that of the first vibrator 130-1 and the sixth vibrator 130-6, respectively.

[0290] According to embodiments of this specification, in each of the first to nth vibrating devices, the fraction (or magnitude) of the first vibrating portion 131 can increase as you move from the first and nth regions (or the center) of the vibrating member 110 towards the edges of the vibrating member 110. For example, the fraction (or magnitude) of the first vibrating portion 131 can be configured to increase more than the fraction (or magnitude) of the second vibrating portion 132 as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or the edges). According to embodiments of this specification, the fraction (or magnitude) of the first vibrating portion 131 can be configured to increase as you move from the first and nth regions (or the center) of the vibrating member 110 towards the edges of the vibrating member 110, while the fraction (or magnitude) of the second vibrating portion 132 can be configured to decrease. The third vibrator 130-3 and the fourth vibrator 130-4 may be configured to have the same or substantially the same fraction (or magnitude) as the first vibrator 131 and the second vibrator 132. For example, if the object is located in the center of the vibrating member 110, the third vibrator 130-3 and the fourth vibrator 130-4 are located close to the object, so the fractions (or magnitudes) of the first vibrator 131 and the second vibrator 132 may be configured to be the same as each other. For example, a device or soundbar that outputs sound including low-frequency and high-frequency ranges can be provided in the center of the vibrating member 110. According to embodiments of this specification, the first vibrator 130-1 to the third vibrator 130-3 may be arranged symmetrically with respect to the center of the vibrating member 110 in reverse order to the fourth vibrator 130-4 to the sixth vibrator 130-6. According to embodiments of this specification, it is possible to provide a device or soundbar in which the low-frequency sound is further increased than the high-frequency sound as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or the edges). For example, by configuring the vibrating member 110 so that the fraction (or magnitude) of the first vibrating part 131 increases more than the fraction (or magnitude) of the second vibrating part 132 as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or the edges), it is possible to provide a device or soundbar in which the low-frequency sound is further increased, taking into account the position of the object.For example, the vibrating member 110 is configured such that the fraction (or magnitude) of the first vibrating portion 131 increases from the center towards both ends (E1, E2) (or edges) compared to the fraction (or magnitude) of the second vibrating portion 132, thereby providing a device or soundbar with a uniform frequency range to the object (or user). For example, the device or soundbar includes first to n vibrating devices arranged in the first to n regions of the vibrating member 110, and the magnitudes of the first vibrating portion 131 and the second vibrating portion 132 of the first to n vibrating devices are configured to be different from each other, so that the sound output from one or more of the first to n regions of the vibrating member 110 has a different frequency range than the sound output from the remaining regions.

[0291] Referring to Figure 18B, the first vibrator 130-1 and the sixth vibrator 130-6 may consist of the first vibrating section 131. For example, assuming the object is located at the center, the first vibrator 130-1 and the sixth vibrator 130-6, which are located at a distance from the object, may consist of the first vibrating section 131. The second vibrator 130-2 and the fifth vibrator 130-5 may be configured such that the fractions (or magnitudes) of the first vibrating section 131 and the second vibrating section 132 are identical or substantially identical. The third vibrator 130-3 and the fourth vibrator 130-4 may consist of the second vibrating section 132. This allows for a device or soundbar that outputs high-frequency sounds at a location close to the object, when the object is located at the center of the vibrating member 110. According to embodiments of this specification, in each of the first to nth vibrating devices, the magnitude of the second vibrating portion 132 may be configured to increase from each of the first to nth regions of the vibrating member 110 (or one of the first and nth regions of the vibrating member 110) towards the center of the vibrating member 110. For example, since the second vibrating portion 132 is configured in the center of the vibrating member 110, a device or soundbar that outputs high-frequency sounds can be provided in the center of the vibrating member 110. The device in Figure 18B may be a device or soundbar that further enhances the low-frequency sounds than the device in Figure 18A. According to embodiments of this specification, with respect to the center of the vibrating member 110, the first vibrating devices 130-1 to the third vibrating devices 130-3 may be arranged symmetrically with respect to each other in reverse order to the fourth vibrating device 130-4 to the sixth vibrating device 130-6. According to embodiments of this specification, a device or soundbar can be provided that outputs sound including high-frequency to low-frequency ranges as you move from the center of the vibrating member 110 to both ends (E1, E2) (or edge portions). For example, since the fraction (or magnitude) of the first vibrating portion 131 increases more than the fraction (or magnitude) of the second vibrating portion 132 as you move from the center of the vibrating member 110 to both ends (E1, E2) (or edge portions), a device or soundbar can be provided that has a greater increase in low-frequency sound.For example, the vibrating member 110 is configured such that the fraction (or magnitude) of the first vibrating portion 131 increases from the center towards both ends (E1, E2) (or edges) compared to the fraction (or magnitude) of the second vibrating portion 132, thereby providing a device or soundbar with a uniform frequency range to the object (or user). For example, the device or soundbar includes first to n vibrating devices arranged in the first to n regions of the vibrating member 110, and the magnitudes of the first vibrating portion 131 and the second vibrating portion 132 of the first to n vibrating devices are configured to be different from each other, so that the sound output from one or more of the first to n regions of the vibrating member 110 has a different frequency range than the sound output from the remaining regions.

[0292] Referring to Figure 18C, the first vibrator 130-1 and the sixth vibrator 130-6 may be configured such that the fractions (or magnitudes) of the first vibrating section 131 and the second vibrating section 132 are the same or substantially the same. For example, assuming that the object is located at the center of the vibrating member 110, the first vibrator 130-1 and the sixth vibrator 130-6, which are located at a distance from the object, can provide a device or soundbar that outputs sound including low and high frequency ranges. The second vibrator 130-2 and the fifth vibrator 130-5 may be configured such that the second vibrating section 132 has a larger fraction (or magnitude) than the first vibrating section 131. The third vibrator 130-3 and the fourth vibrator 130-4 may consist of the second vibrating section 132. This allows for a device or soundbar that outputs high-frequency sound at a location close to the object, when the object is located at the center of the vibrating member 110. According to embodiments of this specification, in each of the first to nth vibrating devices, the magnitude of the second vibrating portion 132 may be configured to increase from each of the first to nth regions of the vibrating member 110 (or one of the first and nth regions of the vibrating member 110) towards the center of the vibrating member 110. For example, since the second vibrating portion 132 is configured in the center of the vibrating member 110, a device or soundbar that outputs high-frequency sounds can be provided in the center of the vibrating member 110. According to embodiments of this specification, a device or soundbar can be configured in which the high-frequency range is further enhanced than the low-frequency range. According to embodiments of this specification, with respect to the center of the vibrating member 110, the first vibrating devices 130-1 to the third vibrating devices 130-3 may be arranged symmetrically with respect to each other in reverse order to the fourth vibrating device 130-4 to the sixth vibrating device 130-6. According to embodiments of this specification, a device or soundbar can be provided that outputs sound including low-frequency and high-frequency ranges from both ends (E1, E2) (or edges) of the vibrating member 110 towards the center. For example, a device or soundbar can be provided in which the high-frequency range sound is further increased from both ends (E1, E2) (or edges) of the vibrating member 110 towards the center.For example, the vibrating member 110 is configured such that the fraction (or magnitude) of the second vibrating part 132 increases from both ends (E1, E2) (or edges) towards the center compared to the fraction (or magnitude) of the first vibrating part 131. This makes it possible to provide a device or soundbar with a uniform frequency range to the object (or user).

[0293] According to the embodiments herein, the aspect ratio of the vibrating parts 131 and 132 may be less than 1. For example, the aspect ratio may be the vertical / horizontal aspect ratio of the vibrating parts 131 and 132. For example, the aspect ratio of the vibrating parts 131 and 132 shown in Figures 18A to 18C may be 1 / 6. For example, the sound pressure of the square first vibrating part 131 may be improved as the aspect ratio decreases.

[0294] According to the embodiments of this specification, it is possible to provide a device that can adjust the acoustics of a desired frequency range by adjusting the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132. For example, since the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132 can be adjusted according to the sound pressure characteristics and / or acoustic characteristics required of the device or soundbar, there is an advantage that the design of the vibration generator 130 is easy. Furthermore, according to the embodiments of this specification, since the vibration generator 130 configured in the device or soundbar can be made thin, the thickness of the device or soundbar can be made thin, and a device or soundbar with a slim design can be provided. Furthermore, according to the embodiments of this specification, since the low-frequency acoustics can be realized with the vibration generator 130 of this specification without configuring a woofer to realize the low-frequency acoustics, the spatial freedom of the device or soundbar can be improved. Furthermore, according to the embodiments of this specification, the device includes first to nth vibrating devices arranged in the first to nth regions of the vibrating member 110, and the sizes of the first vibrating part 131 and the second vibrating part 132 of each of the first to nth vibrating devices are configured to be different from each other. Therefore, it is possible to provide a device or soundbar in which the sound output from one or more of the first to nth regions of the vibrating member 110 has a different frequency range than the sound output from the remaining regions.

[0295] Figures 19A and 19B show apparatus according to other embodiments of this specification.

[0296] Referring to Figures 19A and 18B, the apparatus according to other embodiments of this specification may include a vibrating member 110 and a vibration generating device 130.

[0297] The vibration generator 130 can include at least two or more vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6. For example, the vibration generator 130 can include first to nth (n is a natural number greater than or equal to 2) vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6. For example, the vibration generator 130 can include first to sixth vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6.

[0298] Referring to Figure 19A, the first vibrator 130-1 and the sixth vibrator 130-6 may be configured such that the first vibrating portion 131 has a larger fraction (or magnitude) than the second vibrating portion 132. For example, assuming that the object is located at the center of the vibrating member 110, the first vibrator 130-1 and the sixth vibrator 130-6, which are farther from the object, may be configured such that the fraction (or magnitude) of the first vibrating portion 131 is larger than that of the second vibrating portion 132. The second vibrator 130-2 and the fifth vibrator 130-5 may be configured such that the fractions (or magnitudes) of the first vibrating portion 131 and the second vibrating portion 132 are the same or substantially the same. For example, the second vibrator 130-2 and the fifth vibrator 130-5 can be configured to have a smaller fraction (or magnitude) of the first vibrating portion 131 compared to the first vibrator 130-1 and the sixth vibrator 130-6. According to embodiments of this specification, in each of the first to nth vibrators, the fraction (or magnitude) of the first vibrating portion 131 can increase from the first and nth regions of the vibrating member 110 (or the center of the vibrating member 110) towards the edges of the vibrating member 110. For example, the fraction (or magnitude) of the first vibrating portion 131 can be configured to increase more than the fraction (or magnitude) of the second vibrating portion 132 from the center of the vibrating member 110 towards both ends (E1, E2) (or the edges). The third vibrator 130-3 and the fourth vibrator 130-4 can be configured such that the second vibrating portion 132 has a larger fraction (or magnitude) than the first vibrating portion 131. This makes it possible to provide a device or soundbar that outputs high-frequency sounds at a position close to the object, when the object is located in the center of the vibrating member 110. According to embodiments of this specification, in each of the first to nth vibrating devices, the fraction (or magnitude) of the second vibrating portion 132 can increase from the first and nth regions of the vibrating member 110 (or one of the first and nth regions of the vibrating member 110) towards the center of the vibrating member 110. For example, the second vibrating portion 132 is configured to have a larger fraction (or magnitude) than the first vibrating portion 131 in the center of the vibrating member 110, so that a device or soundbar that outputs high-frequency sounds can be provided in the center of the vibrating member 110.According to embodiments of this specification, the first vibrating devices 130-1 to the third vibrating device 130-3 can be arranged symmetrically with respect to the center of the vibrating member 110, in reverse order to the fourth vibrating device 130-4 to the sixth vibrating device 130-6. According to embodiments of this specification, it is possible to provide a device or soundbar in which the low-frequency sound is further increased than the high-frequency sound as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or edges). For example, the fraction (or magnitude) of the first vibrating part 131 is configured to increase more than the fraction (or magnitude) of the second vibrating part 132 as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or edges), so that a device or soundbar with a uniform frequency range can be provided to the object (or user).

[0299] Figures 18A to 19A show embodiments that include an even number of vibration devices, and Figure 19B may show embodiments that include an odd number of vibration devices.

[0300] Referring to Figure 19B, the vibration device 130 may include the first to fifth vibration devices 130-1, 130-2, 130-3, 130-4, and 130-5.

[0301] The first vibrator 130-1 and the fifth vibrator 130-5 may be configured such that the first vibrating section 131 has a larger fraction (or magnitude) than the second vibrating section 132. For example, assuming that the object is located at the center of the vibrating member 110, the first vibrator 130-1 and the fifth vibrator 130-5, which are farther from the object, may be configured such that the fraction (or magnitude) of the first vibrating section 131 is larger than that of the second vibrating section 132. The second vibrator 130-2 and the fourth vibrator 130-4 may be configured such that the fractions (or magnitudes) of the first vibrating section 131 and the second vibrating section 132 are the same or substantially the same. The third vibrator 130-3 may consist of two first vibrating sections 131 and one second vibrating section 132. In the third vibrator 130-3, the second vibrating section 132 may be positioned between the two first vibrating sections 131. This makes it possible to provide a device or soundbar that outputs low-frequency and high-frequency sounds at a position close to the object, when the object is located at the center of the vibrating member 110. According to embodiments of this specification, the first vibrating device 130-1 and the second vibrating device 130-2 can be arranged symmetrically with respect to the center of the vibrating member 110, in reverse order to the fourth vibrating device 130-4 to the fifth vibrating device 130-5. For example, with respect to the third vibrating part 130-3, the first vibrating device 130-1 and the second vibrating device 130-2 can be arranged symmetrically with respect to the fourth vibrating device 130-4 to the fifth vibrating device 130-5. According to embodiments of this specification, it is possible to provide a device or soundbar that outputs high-frequency to low-frequency sounds as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or edge portions). For example, the vibrating member 110 may be configured such that the fraction (or magnitude) of the first vibrating part 131 increases more than the fraction (or magnitude) of the second vibrating part 132 as you move from the center to both ends (E1, E2) (or the edges). For example, by configuring the vibrating member 110 so that the fraction (or magnitude) of the first vibrating part 131 increases more than the fraction (or magnitude) of the second vibrating part 132 as you move from the center to both ends (E1, E2) (or the edges), it is possible to provide a device or soundbar with a uniform frequency range to the object (or user).

[0302] According to the embodiments of this specification, the aspect ratio of the vibrating parts 131 and 132 may be less than 1. For example, the aspect ratio of the vibrating parts 131 and 132 shown in Figure 19A is 1 / 6, and the aspect ratio of the vibrating parts 131 and 132 shown in Figure 19B may be 1 / 5. For example, the sound pressure of the square first vibrating part 131 may be improved as the aspect ratio decreases.

[0303] According to the embodiments of this specification, it is possible to provide a device that can adjust the acoustics of a desired frequency range by adjusting the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132. For example, since the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132 can be adjusted according to the sound pressure characteristics and / or acoustic characteristics required of the device or soundbar, there is an advantage that the design of the vibration generator 130 is easy. Furthermore, according to the embodiments of this specification, since the vibration generator 130 configured in the device or soundbar can be made thin, the thickness of the device or soundbar can be made thin, and a device or soundbar with a slim design can be provided. Furthermore, according to the embodiments of this specification, since the low-frequency acoustics can be realized with the vibration generator 130 of this specification without configuring a woofer to realize the low-frequency acoustics, the spatial freedom of the device or soundbar can be improved. Furthermore, according to the embodiments of this specification, regardless of the number of vibration generating devices 130 (odd and / or even), the vibration generating device 130 can be implemented with a vibration generating device 130 including a first vibration section 131 and a second vibration section 132, thus improving the design flexibility of the vibration device. Furthermore, according to the embodiments of this specification, the first to nth vibration devices are arranged in the first to nth regions of the vibration member 110, and the first vibration section 131 and the second vibration section 132 of the first to nth vibration devices are configured to have different sizes, so it is possible to provide a device or soundbar in which the sound output from one or more of the first to nth regions of the vibration member 110 has a different frequency range than the sound output from the remaining regions.

[0304] Figures 20A and 20B show apparatus according to other embodiments of this specification.

[0305] Referring to Figures 20A and 20B, these figures show a device or soundbar positioned in a second direction (Y) (or a third direction (Z)). For example, Figures 20A and 20B show the device described in Figures 19A and 19B positioned in a second direction (Y) (or a third direction (Z)). The same reference numerals are used, and redundant descriptions can be omitted or simplified. For example, the third direction (Z) may be parallel to the thickness direction of the vibrating member 110 or the vibration generating device 130.

[0306] Apparatus according to other embodiments of this specification may include a vibrating member 110 and a vibration generating device 130. The vibration generating device 130 may include at least two or more vibration devices 130-1, 130-2, 130-3, 130-4, 130-5, and 130-6.

[0307] Referring to Figure 20A, the first vibrator 130-1 and the sixth vibrator 130-6 may be configured such that the first vibrating portion 131 has a larger fraction (or magnitude) than the second vibrating portion 132. For example, assuming that the object is located at the center of the vibrating member 110, the first vibrator 130-1 and the sixth vibrator 130-6, which are farther from the object, may be configured such that the fraction (or magnitude) of the first vibrating portion 131 is larger than that of the second vibrating portion 132. The second vibrator 130-2 and the fifth vibrator 130-5 may be configured such that the fractions (or magnitudes) of the first vibrating portion 131 and the second vibrating portion 132 are the same or substantially the same. For example, the second vibrator 130-2 and the fifth vibrator 130-5 can be configured to have a smaller fraction (or magnitude) of the first vibrating portion 131 compared to the first vibrator 130-1 and the sixth vibrator 130-6. For example, the fraction (or magnitude) of the first vibrating portion 131 may be configured to increase compared to the fraction (or magnitude) of the second vibrating portion 132 as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or the edges). The third vibrator 130-3 and the fourth vibrator 130-4 may be configured such that the second vibrating portion 132 has a larger fraction (or magnitude) than the first vibrating portion 131. This makes it possible to provide a device or soundbar that outputs high-frequency sounds closer to the object when the object is located at the center of the vibrating member 110. For example, the second vibrating portion 132 in the center of the vibrating member 110 is configured to have a larger fraction (or magnitude) than the first vibrating portion 131, so that a device or soundbar that outputs high-frequency sounds can be provided in the center of the vibrating member 110. According to embodiments of this specification, the first vibrating devices 130-1 to the third vibrating devices 130-3 can be arranged symmetrically with respect to the center of the vibrating member 110 in reverse order to the fourth vibrating devices 130-4 to the sixth vibrating devices 130-6. According to embodiments of this specification, a device or soundbar can be provided in which the low-frequency sounds are further increased than the high-frequency sounds as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or edge portions).For example, the vibration member 110 is configured such that the fraction (or magnitude) of the first vibration portion 131 increases from the center towards both ends (E1, E2) (or the edges) compared to the fraction (or magnitude) of the second vibration portion 132, thereby providing a device or soundbar with a uniform frequency range to the object (or user).

[0308] Referring to Figure 20B, the vibration generator 130 may include the first to fifth vibration devices 130-1, 130-2, 130-3, 130-4, and 130-5.

[0309] The first vibrator 130-1 and the fifth vibrator 130-5 may be configured such that the first vibrating section 131 has a larger fraction (or magnitude) than the second vibrating section 132. For example, assuming that the object is located at the center of the vibrating member 110, the first vibrator 130-1 and the fifth vibrator 130-5, which are farther from the object, may be configured such that the fraction (or magnitude) of the first vibrating section 131 is larger than that of the second vibrating section 132. The second vibrator 130-2 and the fourth vibrator 130-4 may be configured such that the fractions (or magnitudes) of the first vibrating section 131 and the second vibrating section 132 are the same or substantially the same. The third vibrator 130-3 may consist of two first vibrating sections 131 and one second vibrating section 132. In the third vibrator 130-3, the second vibrating section 132 may be positioned between the two first vibrating sections 131. This makes it possible to provide a device or soundbar that outputs low-frequency and high-frequency sounds at a position close to the object, when the object is located at the center of the vibrating member 110. According to embodiments of this specification, the first vibrating device 130-1 and the second vibrating device 130-2 can be arranged symmetrically with respect to the center of the vibrating member 110, in reverse order to the fourth vibrating device 130-4 to the fifth vibrating device 130-5. For example, with respect to the third vibrating part 130-3, the first vibrating device 130-1 and the second vibrating device 130-2 can be arranged symmetrically with respect to the fourth vibrating device 130-4 to the fifth vibrating device 130-5. According to embodiments of this specification, it is possible to provide a device or soundbar that outputs high-frequency to low-frequency sounds as you move from the center of the vibrating member 110 towards both ends (E1, E2) (or edge portions). For example, the vibrating member 110 may be configured such that the fraction (or magnitude) of the first vibrating part 131 increases more than the fraction (or magnitude) of the second vibrating part 132 as you move from the center to both ends (E1, E2) (or the edges). For example, by configuring the vibrating member 110 so that the fraction (or magnitude) of the first vibrating part 131 increases more than the fraction (or magnitude) of the second vibrating part 132 as you move from the center to both ends (E1, E2) (or the edges), it is possible to provide a device or soundbar with a uniform frequency range to the object (or user).

[0310] According to the embodiments of this specification, the aspect ratio of the vibrating parts 131 and 132 may be greater than 1. For example, the aspect ratio of the vibrating parts 131 and 132 shown in Figure 20A is 6, and the aspect ratio of the vibrating parts 131 and 132 shown in Figure 20B may be 5. For example, the sound pressure of the square first vibrating part 131 may be improved as the aspect ratio increases.

[0311] According to the embodiments of this specification, it is possible to provide a device that can adjust the acoustics of a desired frequency range by adjusting the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132. For example, since the fraction (or magnitude) of the first vibrating part 131 and the second vibrating part 132 can be adjusted according to the sound pressure characteristics and / or acoustic characteristics required of the device or soundbar, there is an advantage that the design of the vibration generator 130 is easy. Furthermore, according to the embodiments of this specification, since the vibration generator 130 configured in the device or soundbar can be made thin, the thickness of the device or soundbar can be made thin, and a device or soundbar with a slim design can be provided. Furthermore, according to the embodiments of this specification, since the low-frequency acoustics can be realized with the vibration generator 130 of this specification without configuring a woofer to realize the low-frequency acoustics, the spatial freedom of the device or soundbar can be improved. Furthermore, according to the embodiments of this specification, regardless of the number of vibration generating devices 130 (odd and / or even), the vibration generating device 130 can be implemented with a vibration generating device 130 including a first vibration section 131 and a second vibration section 132, thus improving the design flexibility of the vibration device. Furthermore, according to the embodiments of this specification, the first to nth vibration devices are arranged in the first to nth regions of the vibration member 110, and the first vibration section 131 and the second vibration section 132 of the first to nth vibration devices are configured to have different sizes, so it is possible to provide a device or soundbar in which the sound output from one or more of the first to nth regions of the vibration member 110 has a different frequency range than the sound output from the remaining regions.

[0312] Figures 21 and 21B show apparatus according to other embodiments of this specification.

[0313] Referring to Figures 21A and 21B, these figures show devices or soundbars arranged in the first and second directions (X, Y). For example, since Figures 21A and 21B are identical or substantially the same as those described in Figures 19A and 19B, the same reference numerals are used, and redundant explanations can be omitted or simplified.

[0314] Apparatus according to other embodiments of this specification may include a vibrating member 110 and a vibration generator 130. The vibration generator 130 may include at least two or more vibration devices 130-1, 130-2, 130-3, 130-4. For example, Figure 21A shows an apparatus or soundbar with an even number of vibration generators arranged. For example, the vibration generator 130 in Figure 21A may be a 2x2 array, and the embodiments of this specification are not limited to this terminology.

[0315] Referring to Figure 21A, the first vibration devices 130-1 to the fourth vibration devices 130-4 may be configured such that the fraction (or magnitude) of the first vibration section 131 is greater than the fraction (or magnitude) of the second vibration section 132. For example, the first vibration devices 130-1 to the fourth vibration devices 130-4 may be identically configured such that the fraction (or magnitude) of the first vibration section 131 is greater than the fraction (or magnitude) of the second vibration section 132. The embodiments herein are not limited thereto, and the first vibration devices 130-1 to the fourth vibration devices 130-4 may be configured such that the fraction (or magnitude) of the first vibration section 131 is greater than the fraction (or magnitude) of the second vibration section 132, and have different fractions (or magnitudes) from each other. For example, the fraction (or magnitude) of the second vibrating section 132 of the first vibrating device 130-1 and the fraction (or magnitude) of the second vibrating section 132 of the second vibrating device 130-2 may be configured to be greater than or less than the fraction (or magnitude) of the second vibrating section 132 of the third vibrating device (130-3) and the fraction (or magnitude) of the second vibrating section 132 of the fourth vibrating device (130-4). For example, the fraction (or magnitude) of the second vibrating section 132 of the first vibrating device 130-1 and the fraction (or magnitude) of the second vibrating section 132 of the third vibrating device 130-3 may be configured to be greater than or less than the fraction (or magnitude) of the second vibrating section 132 of the second vibrating device (130-2) and the fraction (or magnitude) of the second vibrating section 132 of the fourth vibrating device (130-4). For example, a first vibrating section 131 may be arranged on the edge portion of the vibrating member 110. For example, a second vibrating section 132 may be positioned on one side edge of the first vibrating device 130-1 to the fourth vibrating device 130-4. For example, a second vibrating section 132 may be positioned in the center of the vibrating member 110. According to the embodiments of this specification, the first vibrating section 131 of each of the first to n vibrating devices may be positioned closer to the edge of the vibrating member 110 than the second vibrating section 132, and the second vibrating section 132 of each of the first to n vibrating devices may be positioned closer to the center of the vibrating member 110 than the first vibrating section 131. Furthermore, according to the embodiments of this specification, the center of the vibrating member 110 outputs high-frequency sounds, and the sound output becomes lower in frequency ranges as you move from the center of the vibrating member 110 towards the edge, so it is possible to provide a device or soundbar that includes a vibrating device having a uniform frequency range from low to high frequencies.Furthermore, according to the embodiments of this specification, since the first vibrating part 131 is positioned adjacent to the center of the vibrating member 110 and the second vibrating part 132 is positioned around the first vibrating part 131 or the vibrating member 110, it is possible to have a more balanced sound pressure characteristic of low and high frequencies than when a single vibrating device (e.g., the first vibrating part 131 or the second vibrating part 132) is used. In the case of high frequencies, there is a disadvantage that the wavelength is shorter compared to low frequencies and the sound does not travel far, but when implemented in a vibrating device (or acoustic device), the addition of the first vibrating part 131 can increase the sound transmission distance of the vibrating device (or acoustic device or speaker) and also enhance the bass.

[0316] Referring to Figure 21B, the vibration generator 130 may include at least two or more vibration devices 130-1 to 130-9. For example, the vibration generator 130 may include the first to ninth vibration devices 130-1 to 130-9. For example, Figure 21B shows a device or soundbar with an odd number of vibration devices arranged. For example, the vibration generator 130 in Figure 21B may be a 3x3 array, and the embodiments herein are not limited to this term. For example, the vibration generator 130 in Figure 21B may have improved sound pressure characteristics and / or acoustic characteristics because the area of ​​the vibration generator 130 is increased compared to Figure 21A.

[0317] The first vibrator 130-1 and the third vibrator 130-3 may be configured such that the fraction (or magnitude) of the first vibrating section 131 is greater than the fraction (or magnitude) of the second vibrating section 132. For example, the fraction (or magnitude) of the first vibrating section 131 of the first vibrator 130-1 may be configured to be the same as or substantially the same as the fraction (or magnitude) of the third vibrator 130-3. For example, the fraction (or magnitude) of the second vibrating section 132 of the first vibrator 130-1 may be configured to be the same as or substantially the same as the fraction (or magnitude) of the third vibrator 130-3. The first vibrator 130-1 and the third vibrator 130-3 may be arranged symmetrically with respect to the center of the vibrating member 110. For example, the first vibrator 130-1 and the third vibrator 130-3 may be arranged symmetrically with respect to the second vibrator 130-2.

[0318] The second vibrator 130-2 and the eighth vibrator 130-8 may be configured such that the fraction (or magnitude) of the first vibrating section 131 and the fraction (or magnitude) of the second vibrating section 132 are identical or substantially identical to each other. For example, the fraction (or magnitude) of the first vibrating section 131 of the second vibrator 130-2 may be configured to be identical or substantially identical to the fraction (or magnitude) of the eighth vibrator 130-8. For example, the fraction (or magnitude) of the second vibrating section 132 of the second vibrator 130-2 may be configured to be identical or substantially identical to the fraction (or magnitude) of the eighth vibrator 130-8. The second vibrator 130-2 and the eighth vibrator 130-8 may be arranged symmetrically with respect to the center of the vibrating member 110. For example, the second vibration device 130-2 and the eighth vibration device 130-8 may be arranged symmetrically with respect to the fifth vibration device 130-5.

[0319] The fourth vibrator 130-4 and the sixth vibrator 130-6 may be configured such that the fraction (or magnitude) of the first vibrating section 131 and the fraction (or magnitude) of the second vibrating section 132 are identical or substantially identical to each other. For example, the fraction (or magnitude) of the first vibrating section 131 of the fourth vibrator 130-4 may be configured to be identical or substantially identical to the fraction (or magnitude) of the sixth vibrator 130-6. For example, the fraction (or magnitude) of the second vibrating section 132 of the fourth vibrator 130-4 may be configured to be identical or substantially identical to the fraction (or magnitude) of the sixth vibrator 130-6. The fourth vibrator 130-4 and the sixth vibrator 130-6 may be arranged symmetrically with respect to the center of the vibrating member 110. For example, the fourth vibration device 130-4 and the sixth vibration device 130-6 may be arranged symmetrically with respect to the fifth vibration device 130-5.

[0320] The seventh vibrator 130-7 and the ninth vibrator 130-9 may be configured such that the fraction (or magnitude) of the first vibrating section 131 is greater than the fraction (or magnitude) of the second vibrating section 132. For example, the fraction (or magnitude) of the first vibrating section 131 of the seventh vibrator 130-7 may be configured to be the same as or substantially the same as the fraction (or magnitude) of the ninth vibrator 130-9. For example, the fraction (or magnitude) of the second vibrating section 132 of the seventh vibrator 130-7 may be configured to be the same as or substantially the same as the fraction (or magnitude) of the ninth vibrator 130-9. The seventh vibrator 130-7 and the ninth vibrator 130-9 may be arranged symmetrically with respect to the center of the vibrating member 110. For example, the seventh vibrator 130-7 and the ninth vibrator 130-9 may be arranged symmetrically with respect to the eighth vibrator 130-8.

[0321] The fifth vibrating device 130-5 may be configured such that the fraction (or magnitude) of the first vibrating section 131 is larger than the fraction (or magnitude) of the second vibrating section 132. For example, the second vibrating section 132 may be located in the center of the fifth vibrating device 130-5. For example, the first vibrating section 131 of the fifth vibrating device 130-5 may surround the second vibrating section 132.

[0322] The first vibrator 130-1, the fourth vibrator 130-4, and the seventh vibrator 130-7 can be arranged symmetrically with respect to the center of the vibrating member 110, along with the third vibrator 130-3, the sixth vibrator 130-6, and the ninth vibrator 130-9.

[0323] According to the embodiments of this specification, the first vibrating portion 131 of each of the first to n vibrating devices may be positioned closer to the edge of the vibrating member 110 than the second vibrating portion 132, and the second vibrating portion 132 of each of the first to n vibrating devices may be positioned closer to the center of the vibrating member 110 than the first vibrating portion 131. Furthermore, according to the embodiments of this specification, the center of the vibrating member 110 outputs high-frequency sounds, and the sound output becomes lower in frequency ranges as you move from the center to the edge of the vibrating member 110, so it is possible to provide a device or soundbar that includes a vibrating device having a uniform frequency range from low to high frequencies. Furthermore, according to the embodiments of this specification, the first to n vibrating devices are arranged in the first to n regions of the vibrating member 110, and the first vibrating portion 131 and the second vibrating portion 132 of the first to n vibrating devices are configured to have different sizes, so it is possible to provide a device or soundbar in which the sound output from one or more of the first to n regions of the vibrating member 110 has a different frequency range than the sound output from the remaining regions. Furthermore, according to the embodiments of this specification, since the first vibrating part 131 is positioned adjacent to the center of the vibrating member 110 and the second vibrating part 132 is positioned around the first vibrating part 131, it is possible to have a more balanced sound pressure characteristic of low and high frequencies than when a single vibrating device (e.g., the first vibrating part 131 or the second vibrating part 132) is used. In the case of high frequencies, there is a disadvantage that the wavelength is shorter compared to low frequencies and sound cannot be transmitted over long distances, but when implemented in a vibrating device (or acoustic device), the addition of the first vibrating part 131 increases the sound transmission distance of the vibrating device (or acoustic device or speaker) and also enhances the bass.
