[0002] This application claims the benefit of Korean Patent Application No. 10-2023-0101771 filed in Korea on August 3, 2023, which is hereby incorporated by reference into this application in its entirety. Technical Field

[0003] The present disclosure relates to a device. Background Art

[0004] The device includes a separate speaker or a sound generating device for providing sound. When the speaker is in the display device, the speaker occupies space, and therefore, the design and spatial layout of the display device are limited.

[0005] A speaker applied to a device may be, for example, an actuator including a magnet and a coil. However, when the actuator is applied to a device, its thickness becomes thick. Therefore, a piezoelectric device for achieving a thin thickness has received much attention. Summary of the invention

[0006] The sound generated in the speaker or sound-emitting device embedded in the device is output in the rear or side direction of the device rather than in the front direction of the device, and therefore, is not propagated toward the viewer or user who is viewing the image in the front area relative to the device or display device. Therefore, there is a problem that the immersive experience of the viewer viewing the image is hindered.

[0007] Therefore, the inventors of the present disclosure have recognized the above problems and have conducted extensive research and experiments to realize a device capable of enhancing sound quality and sound pressure level characteristics. Through extensive research and experiments, the inventors of the present disclosure have invented a device capable of enhancing sound quality and sound characteristics and / or sound pressure level characteristics.

[0008] Accordingly, embodiments of the present disclosure are directed to an apparatus that substantially obviates one or more problems due to limitations and disadvantages of the related art.

[0009] One aspect of the present disclosure provides an apparatus that can vibrate a vibration member to generate sound or vibration, thereby enhancing sound characteristics and / or sound pressure level characteristics.

[0010] Additional features, advantages and aspects of the present disclosure are partially set forth in the present disclosure, and will also be apparent from the present disclosure, or can be learned by practicing the inventive concepts provided herein.

[0011] To achieve these and other advantages and aspects of the present disclosure, as embodied and broadly described herein, in one or more aspects, a device may include: a vibration member; a vibration device configured to vibrate the vibration member, the vibration device including a long side and a short side; and a pad member connected to a rear surface of the vibration device. The pad member may include a linear shape having a length direction parallel to the long side of the vibration device or inclined relative to the length direction of the long side of the vibration device.

[0012] The device according to one embodiment of the present disclosure may vibrate the vibration member to generate sound, and may output the sound having enhanced sound characteristics and / or sound pressure level characteristics in a front direction of the vibration member.

[0013] According to one embodiment of the present disclosure, a pad member may be configured on a rear surface of a vibration device, thereby providing a device that can enhance sound characteristics and / or sound pressure level characteristics in a mid-high frequency band.

[0014] According to one embodiment of the present disclosure, a pad member may be configured on a rear surface of a vibration device, thereby providing a device for improving peaks and / or valleys in a high frequency band.

[0036] Throughout the drawings and detailed description, unless otherwise described, the same drawing reference numerals should be understood to refer to the same elements, features, and structures. The size, length, thickness, and description of layers, regions, and elements may be exaggerated for clarity, illustration, and convenience. DETAILED DESCRIPTION

[0037] Reference is now made in detail to aspects of the present disclosure, examples of which may be illustrated in the accompanying drawings. In the following description, when a detailed description of a known method, function, structure, or configuration may unnecessarily obscure aspects of the present disclosure, a detailed description of such known function or configuration may be omitted for the sake of brevity. In addition, for the sake of brevity, a repeated description thereof may be omitted. The described progression of processing steps and / or operations is a non-limiting example.

[0038] The order of steps and / or operations is not limited to the order described herein, and can be changed to occur in an order different from the order described herein, except for steps and / or operations that must occur in a specific order. In one or more examples, two operations in succession can be performed substantially simultaneously, or the two operations can be performed in a reverse order or a different order depending on the functions or operations involved.

[0039] Unless otherwise specified, the same reference numerals may refer to the same elements even if they are shown in different figures. Unless otherwise specified, throughout the specification and drawings, the same reference numerals may be used to refer to the same or substantially the same elements. In one or more aspects, the same elements (or elements with the same names) in different figures may have the same or substantially the same functions and characteristics unless otherwise specified. The names of the various elements used in the following description are selected for convenience only and, therefore, may be different from the names used in the actual product.

[0040] The advantages and features of the present disclosure and their implementation methods are illustrated by referring to the aspects described in the accompanying drawings. However, the present disclosure can be implemented in different forms and should not be interpreted as being limited to the example aspects set forth herein. On the contrary, these example aspects are examples, and these example aspects are provided so that the present disclosure can be thorough and complete, to help those skilled in the art understand the inventive concept, without limiting the scope of protection of the present disclosure.

[0041] The shapes, dimensions (e.g., size, length, width, height, thickness, position, radius, diameter, and area), proportions, ratios, angles, quantities, number of elements, etc. disclosed herein, including those shown in the drawings, are merely examples, and therefore, the disclosure is not limited to the details shown. However, it should be noted that the relative dimensions of the components shown in the drawings are part of the disclosure.

[0042] For one or more elements (e.g., layers, films, regions, components, sections, members, parts, areas, portions, steps, operations, etc.), when terms such as "including", "having", "comprising", "containing", "consisting of", "made of", "formed of", etc. are used, one or more other elements may be added unless terms such as "only" are used. The terms used in the present disclosure are only used to describe specific example aspects and are not intended to limit the scope of the present disclosure. Unless the context clearly indicates otherwise, terms in the singular may include plural forms.

[0043] Unless otherwise stated, the word "exemplary" is used to mean serving as an example or illustration. An embodiment is an example embodiment. An aspect is an example aspect. Here, in one or more implementations, "embodiments," "aspects," "examples," etc. should not be construed as being preferred or advantageous over other implementations. Unless otherwise stated, an aspect, an example, an example aspect, etc. may refer to one or more aspects, one or more examples, one or more example aspects, etc. In addition, the term "may" includes all meanings and coverage of the term "can."

[0044] In one or more aspects, unless otherwise expressly stated, an element, feature, or corresponding information (e.g., level, range, dimension, size, etc.) is interpreted as including an error or tolerance range, even if no explicit description of such error or tolerance range is provided. The error or tolerance range may be caused by various factors (e.g., process factors, internal or external influences, noise, etc.). When interpreting a numerical value, unless otherwise expressly stated, the value is interpreted as including an error range.

[0045] When describing a positional relationship, when two components (e.g., layers, films, regions, components, parts, etc.) are described using, for example, “on,” “over,” “on top of,” “over,” “under,” “above,” “below,” “near,” “near,” “adjacent,” “beside,” “near,” “on one side or one side,” etc., one or more other components may be located between the two components unless more restrictive terms such as “immediately adjacent,” “directly,” or “close to,” etc. are used. For example, when a structure is described as being relative to another structure, When positioned as follows: "on", "over", "on top of", "above", "below", "above", "below", "below", "near", "close", "adjacent", "beside", "near", "on one side or on the side", etc., the description should be interpreted to include the situation where the structures are in contact with each other and the situation where one or more additional structures are arranged or inserted therebetween. In addition, the terms "front", "back", "back", "left", "right", "top", "bottom", "downward", "upward", "upper", "lower", "up", "down", "column", "row", "vertical", "horizontal", etc. refer to an arbitrary reference system.

[0046] Spatially relative terms such as "below", "beneath", "below", "above", and the like may be used to describe the relationship between various elements (e.g., layers, films, regions, components, parts, etc.) shown in the drawings. Spatially relative terms should be understood to include terms for different orientations of elements in use or operation in addition to the orientations shown in the drawings. For example, if the elements shown in the drawings are flipped, elements described as being "below" or "below" other elements will be oriented to be "above" the other elements. Therefore, the term "below" as an exemplary term may include all directions of "above" and "below". Similarly, the exemplary terms "above" or "on" may include both the directions of "above" and "below".

[0047] When describing a temporal relationship, when the temporal order is described as, for example, "after", "subsequently", "next", "before", "previously", "in front of", etc., discontinuity or non-sequential situations may be included, and therefore, one or more other events may occur in between, unless more restrictive terms such as "just after", "immediately" or "directly" are used.

[0048] Terms such as "below," "lower," "above," "upper," etc. may be used to describe the relationship between elements shown in the drawings. It should be understood that these terms are spatially relative and based on the orientation shown in the drawings.

[0049] It should be understood that, although the terms "first", "second", etc. can be used to describe various elements (e.g., layers, films, regions, components, parts, members, parts, regions, regions, parts, steps, operations, etc.) in this article, these elements should not be limited by these terms, for example, any specific order, sequence, priority or quantity of elements. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present disclosure, the first element can be referred to as the second element, and similarly, the second element can be referred to as the first element. In addition, without departing from the scope of the present disclosure, the first element, the second element, etc. can be arbitrarily named according to the convenience of those skilled in the art. For the sake of clarity, the function or structure of these elements (e.g., the first element, the second element, etc.) is not limited by the ordinal number or name in front of the element. In addition, the first element may include one or more first elements. Similarly, the second element, etc. may include one or more second elements, etc.

[0050] When describing elements of the present disclosure, terms such as "first", "second", "A", "B", "(a)", "(b)", etc. may be used. These terms are intended to identify corresponding elements with other elements, and these terms are not used to define the nature, basis, order, sequence or number of the elements.

[0051] When an element (for example, a layer, a film, a region, a component, a part, etc.) is described as being “connected,” “bonded,” “attached,” “adhered,” etc. to another element, unless otherwise specified, the element may not only be directly connected, bonded, attached, adhered, etc. to the other element but may also be indirectly connected, bonded, attached, adhered, etc. to the other element by arranging or inserting one or more intervening elements between the elements.

[0052] When an element (for example, a layer, film, region, component, part, etc.) is “contacted”, “overlapped”, etc. with another element, unless otherwise specified, the element may not only be directly in contact with, overlapped with, etc., but may also be indirectly in contact with, overlapped with, etc., with the other element by arranging or inserting one or more intervening elements between the elements.

[0053] Phrases where an element (e.g., a layer, a film, a region, a component, a part, etc.) is “disposed in”, “arranged on”, “connected to”, “bonded to”, etc., may be understood to mean, for example, that at least a portion of the element is disposed in, disposed on, connected to, or bonded to at least a portion of the other element, or that the entire element is disposed in, disposed on, connected to, or bonded to the other element, etc. Phrases where an element (e.g., a layer, a film, a region, a component, a part, etc.) is “in contact with”, “overlaps”, etc., and another element may be understood to mean, for example, that at least a portion of the element is in contact with, overlaps, etc., and at least a portion of the other element, or the entire element is in contact with, overlaps, etc., and at least a portion of the other element, or at least a portion of the element is in contact with, overlaps, etc., and the entire element is in contact with, overlaps, etc., and the entire element is in contact with, overlaps, etc., and the entire element is in contact with, overlaps, etc.

[0054] Terms such as "line" or "direction" should not be interpreted based solely on the geometric relationship of the corresponding lines or directions being parallel or perpendicular to each other. Such terms may refer to lines or directions that have a wider directionality within the scope of functional operation of the components of the present disclosure. For example, the terms "first direction", "second direction", etc., such as directions parallel or perpendicular to the "x-axis", "y-axis", or "z-axis", should not be interpreted based solely on the geometric relationship of the respective directions being parallel or perpendicular to each other, and may refer to directions that have a wider directionality within the scope of functional operation of the components of the present disclosure.

[0055] The term "at least one" should be understood to include any and all combinations of one or more of the associated listed items. For example, each of the phrases "at least one of the first, second, or third items" and "at least one of the first, second, and third items" can mean (i) a combination of items provided by one or more of the first, second, and third items, or (ii) only one of the first, second, and third items.

[0056] The expression of a first element, a second element “and / or” a third element should be understood to include one of the first element, the second element, and the third element, and any and all combinations of the first element, the second element, and the third element. By way of example, A, B, and / or C include only A; only B; only C; any one of A, B, and C (e.g., A, B, or C); some combination of A, B, and C (e.g., A and B; A and C; or B and C); and all of A, B, and C. In addition, the expression “A / B” may be understood as A and / or B. For example, the expression “A / B” may refer to only A; only B; A or B; or A and B.

[0057] In one or more aspects, unless otherwise stated, the terms "between" and "among" may be used interchangeably simply for convenience. For example, the expression "between a plurality of elements" may be understood as among a plurality of elements. In another example, the expression "among a plurality of elements" may be understood as between a plurality of elements. In one or more examples, the number of elements may be two. In one or more examples, the number of elements may be more than two. In addition, when an element (e.g., a layer, film, region, component, portion, etc.) is referred to as being "between at least two elements," the element may be the only element between the at least two elements, or one or more intervening elements may also be present.

[0058] In one or more aspects, unless otherwise specified, the phrases "each other" and "mutually" may be used interchangeably simply for convenience. For example, a statement "different from each other" may be understood to be different from each other. In another example, a statement "different from each other" may be understood to be different from each other. In one or more examples, the number of elements involved in the foregoing statements may be two. In one or more examples, the number of elements involved in the foregoing statements may be more than two.

[0059] In one or more aspects, the phrases "one or more of" and "one or more of" may be used interchangeably simply for convenience unless otherwise stated.

[0060] The term "or" means an inclusive or, not an exclusive or. For example, unless stated otherwise or clear from the context, the statement "x employs a or b" means any of the natural inclusive permutations. For example, "a or b" may mean "a," "b," or "a and b." For example, "a, b or c" may mean "a," "b," "c," "a and b," "b and c," "a and c," or "a, b, and c."

[0061] Unless otherwise defined, the terms (including technical and scientific terms) used herein have the same meaning as commonly understood by a person of ordinary skill in the art to which the exemplary aspects belong. It should be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless otherwise explicitly defined herein.

[0062] The terms used herein are selected as common terms in the relevant technical field, however, other terms may exist according to the development and / or change of technology, convention, preference of technicians, etc. Therefore, the terms used herein should not be understood as limiting the technical concept, but should be understood as examples of terms used to describe exemplary aspects.

[0063] In addition, in certain cases, the terms may be arbitrarily selected by the applicant, and in this case, their detailed meanings are described in this document. Therefore, the terms used in this document should be understood not only based on the term names, but also based on the meanings of the terms and their contents.

[0064] Furthermore, the “X-axis direction”, “Y-axis direction”, and “Z-axis direction” should not be interpreted only by the geometric relationship of being perpendicular to each other, and the elements of the present disclosure may have wider directivities within the scope of functional operations.

[0065] In the present disclosure, the display device may include a display device such as an organic light emitting display (OLED) module or a liquid crystal module (LCM), the OLED module or the LCM including a display panel and a driver for driving the display panel.

[0066] Therefore, the display device in the present disclosure may include the display device itself, such as an LCM or OLED module, as well as a complete device as an end-consumer device or an application product including the LCM or OLED module.

[0067] In addition, in some embodiments, an LCM or OLED module configured with a display panel and a driver, etc., may be referred to as a display device, and an electronic device including a final product of the LCM or OLED module may be referred to as a complete set of equipment. For example, a display device may include a display panel such as an LCD or OLED and a source printed circuit board (PCB) as a controller for driving the display panel. The complete set of equipment may further include a complete set of PCBs as a complete set of controllers electrically connected to the source PCB to control the complete set of equipment as a whole.

[0071] The display panel may further include a back plate, such as a metal plate attached to the display panel. However, the present embodiment is not limited to the metal plate, and the display panel may include another structure made of other materials.

[0072] The features of various aspects of the present disclosure may be partially or completely combined or combined with each other, may be technically interrelated, and may be operated, linked or driven together in various ways. Various aspects of the present disclosure may be implemented or executed independently of each other, or may be implemented or executed together in a mutually dependent or related relationship.

For example, the pad member 600 may be connected to any one of the first cover member 213a and the second cover member 213d to overlap with the vibration component 211. For example, the pad member 600 may be connected to any one of the second adhesive layer 213c and the second cover member 213d to overlap with the vibration component 211. For example, the pad member 600 may be connected to the rear surface 200b of the second cover member 213d to overlap with the vibration component 211. Fig.11 and Fig.12 The pad member 600 described above may be changed to Figure 5 The pad member 700 described above may be changed to Figure 6 The pad member 800 is described above, and thus, a repeated description thereof may be omitted.

The cover member 213 may be configured to cover one or more of a first surface and a second surface of a vibration component 211 of each of the first vibration device 201 and the second vibration device 202. The pad member 600 may be connected to the cover member 213 to overlap with the vibration component 211 of each of the first vibration device 201 and the second vibration device 202. For example, the pad member 600 may be connected to any one of the first cover member 213a and the second cover member 213d to overlap with the vibration component 211 of each of the first vibration device 201 and the second vibration device 202.

[0290] The vibration device 200 according to one embodiment of the present disclosure may further include a signal supply member 250 .

[0291] The signal supply member 250 may be configured to supply a driving signal provided from the driving circuit part to the vibration part 211. The signal supply member 250 may be configured to be electrically connected to the vibration part 211. The signal supply member 250 may be configured to be electrically connected to the first electrode layer 211b and the second electrode layer 211c of the vibration part 211.

[0292] A portion of the signal supply member 250 may be accommodated (or inserted) between the cover member 213 and the vibration component 211. For example, a portion of the signal supply member 250 may be accommodated (or inserted) between the first surface of the vibration component 211 and the first cover member 213a. For example, a portion of the signal supply member 250 may be accommodated (or inserted) between the first cover member 213a and the second cover member 213d.

[0293] According to one embodiment of the present disclosure, an end (or a distal end or one side or a portion) of the signal supply member 250 may be arranged or inserted (or accommodated) between one peripheral portion of the cover member 213 and the vibration component 211. For example, an end (or a distal end or one side or a portion) of the signal supply member 250 may be arranged or inserted (or accommodated) between one peripheral portion of the first cover member 213a and the first surface of the vibration component 211.

[0294] According to another embodiment of the present disclosure, the end (or distal end or one side or part) of the signal supply member 250 can be arranged or inserted (or accommodated) between a peripheral portion of the first cover member 213a and a peripheral portion of the second cover member 213d. A peripheral portion of the first cover member 213a and a peripheral portion of the second cover member 213d can accommodate or cover the end (or distal end or one side or part) of the signal supply member 250 in the vertical direction (or up and down). Therefore, the signal supply member 250 can be integrated with the vibration device 200. For example, the signal supply member 250 can be configured as a signal cable, a flexible cable, a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multi-layer printed circuit, or a flexible multi-layer printed circuit board, but the embodiments of the present disclosure are not limited thereto.

[0295] The signal supply member 250 according to one embodiment of the present disclosure may include a base member 251 and a plurality of signal lines 252a and 252b. For example, the signal supply member 250 may include a base member 251, a first signal line 252a, and a second signal line 252b.

[0296] The base member 251 may include a transparent or opaque plastic material, but the embodiments of the present disclosure are not limited thereto. The base member 251 may have a certain width along the first direction X, and may extend long along a second direction Y intersecting the first direction X.

[0297] The first signal line 252a and the second signal line 252b may be arranged on the first surface of the base member 251 in parallel with the second direction Y, and may be spaced apart from or electrically separated from each other along the first direction X. The first signal line 252a and the second signal line 252b may be arranged on the first surface of the base member 251 in parallel with each other. For example, the first signal line 252a and the second signal line 252b may be implemented in a linear shape by patterning a metal layer (or a conductive layer) formed or deposited on the first surface of the base member 251.

[0298] Ends (or distal ends or one side or a portion) of the first signal line 252a and the second signal line 252b may be separated from each other, and thus, may be individually bent or curved.

[0299] The end (or distal end or one side or part) of the first signal line 252a can be electrically connected to the first electrode layer 211b of the vibration component 211. For example, the end of the first signal line 252a can be electrically connected to at least a portion of the first electrode layer 211b of the vibration component 211 in one peripheral portion of the first cover member 213a. For example, the end (or distal end or one side or part) of the first signal line 252a can be directly electrically connected to at least a portion of the first electrode layer 211b of the vibration component 211. For example, the end (or distal end or one side or part) of the first signal line 252a can be electrically connected to or directly contact the first electrode layer 211b of the vibration component 211. For example, the end of the first signal line 252a can be electrically connected to the first electrode layer 211b by a conductive double-sided tape. Therefore, the first signal line 252a can be configured to provide the first drive signal provided from the drive circuit component to the first electrode layer 211b of the vibration component 211.

[0300] The end (or distal end or one side or a portion) of the second signal line 252b can be electrically connected to the second electrode layer 211c of the vibration component 211. For example, the end of the second signal line 252b can be electrically connected to at least a portion of the second electrode layer 211c of the vibration component 211 in one peripheral portion of the second cover member 213d. For example, the end of the second signal line 252b can be directly electrically connected to at least a portion of the second electrode layer 211c of the vibration component 211. For example, the end of the second signal line 252b can be electrically connected to or directly contact the second electrode layer 211c of the vibration component 211. For example, the end of the second signal line 252b can be electrically connected to the second electrode layer 211c via a conductive double-sided tape. Therefore, the second signal line 252b can be configured to provide the second drive signal provided from the drive circuit component to the second electrode layer 211c of the vibration component 211.

[0301] The signal supply member 250 according to one embodiment of the present disclosure may further include an insulating layer 253 .

[0302] The insulating layer 253 may be disposed on the first surface of the base member 251 and cover each of the first signal line 252 a and the second signal line 252 b except for an end (or one side or a portion) of the signal supply member 250 .

[0303] According to one embodiment of the present disclosure, an end (or one side) of a signal supply member 250 including an end (or one side or a portion) of a base member 251 and an end (or one side or a portion) 253a of an insulating layer 253 can be inserted (or accommodated) between the cover member 213 and the vibration component 211, and can be fixed between the cover member 213 and the vibration component 211 by a first adhesive layer 213b and a second adhesive layer 213c.

[0304] According to one embodiment of the present disclosure, an end (or one side) of a signal supply member 250 including an end (or one side) of a base member 251 and an end (or one side or a portion) 253a of an insulating layer 253 may be inserted (or accommodated) between the first cover member 213a and the second cover member 213d, and may be fixed between the first cover member 213a and the second cover member 213d by a first adhesive layer 213b and a second adhesive layer 213c. Therefore, an end (or one side or a portion) of a first signal line 252a may remain electrically connected to the first electrode layer 211b of the vibration component 211, and an end (or one side or a portion) of a second signal line 252b may remain electrically connected to the second electrode layer 211c of the vibration component 211. In addition, an end (or one side or a portion) of the signal supply member 250 may be inserted (or accommodated) and fixed between the vibration component 211 and the first cover member 213a, and therefore, a contact defect between the vibration device 200 and the signal supply member 250 caused by movement of the signal supply member 250 may be prevented.

[0305] In the signal supply member 250 according to one embodiment of the present disclosure, each of the end (or one side or a portion) 253a of the base member 251 and the end (or one side or a portion) 253a of the insulating layer 253 may be removed. For example, each of the end of the first signal line 252a and the end of the second signal line 252b may be exposed to the outside without being supported or covered by each of the end (or one side or a portion) 253a of the base member 251 and the end (or one side or a portion) 253a of the insulating layer 253, respectively. For example, the end (or one side or a portion) of each of the first signal line 252a and the second signal line 252b may protrude (or extend) from the end 251e of the base member 251 or the end 253e of the insulating layer 253 to have a certain length. Therefore, the end (or distal end or one side or a portion) of each of the first signal line 252a and the second signal line 252b may be bent individually or independently.

[0306] An end (or one side or a portion) of the first signal line 252a that is not supported by an end (or one side or a portion) of the base member 251 and an end (or one side) 253a of the insulating layer 253 may be directly connected to or directly contact the first electrode layer 211b of the vibration component 211. An end (or one side or a portion) of the second signal line 252b that is not supported by an end (or one side or a portion) of the base member 251 and an end (or one side or a portion) 253a of the insulating layer 253 may be directly connected to or directly contact the second electrode layer 211c of the vibration component 211.

[0307] According to one embodiment of the present disclosure, a portion of the signal supply member 250 or a portion of the base member 251 may be arranged or inserted (or accommodated) between the cover member 213 and the vibration component 211, and thus, the signal supply member 250 may be integrated with the vibration component 211. For example, a portion of the signal supply member 250 or a portion of the base member 251 may be arranged or inserted (or accommodated) between the first cover member 213a and the second cover member 213d, and thus, the signal supply member 250 may be integrated with the vibration device 200. Therefore, the vibration device 200 and the signal supply member 250 may be configured as one component (or one element or one component), and thus, an effect of uni-materialization may be obtained.

[0308] According to one embodiment of the present disclosure, the first signal line 252a and the second signal line 252b of the signal supply member 250 may be integrated with the vibration device 200, and therefore, a welding process for electrical connection between the vibration device 200 and the signal supply member 250 may not be required. Therefore, the manufacturing process and structure of the vibration device 200 may be simplified, and the danger associated with the welding process may be reduced.

Figures 10 to 12 The described vibration layer 211 a is substantially the same, and thus, a repeated description thereof may be omitted or will be briefly given below.

[0313] Each of the plurality of second portions 211a2 may be arranged between the plurality of first portions 211a1.

Therefore, the vibration component 211a may be extended to a desired size or length by combining (or connecting) the sides of the first part 211a1 and the second part 211a2.

[0316] According to one embodiment of the present disclosure, each of the plurality of second parts 211a2 can absorb the impact applied to the first part 211a1, and therefore, the overall durability of the first part 211a1 can be enhanced and flexibility can be provided to the vibration component 211a. Each of the plurality of second parts 211a2 may include an organic material having a ductile property. For example, each of the plurality of second parts 211a2 may include one or more of an epoxy-based polymer, an acrylic-based polymer, and a silicone-based polymer, but the embodiments of the present disclosure are not limited thereto. For example, each of the plurality of second parts 211a2 may be an organic part, an organic material part, an adhesive part, a stretching part, a bending part, a damping part, or an extensible part, but the embodiments of the present disclosure are not limited thereto.

The second surface of each of the plurality of first portions 211a1 and the plurality of second portions 211a2 may be commonly connected to the second electrode layer 211c. As another embodiment of the present disclosure, one or both of the first electrode layer 211b and the second electrode layer 211c may be formed as a pattern-shaped electrode to correspond only to the plurality of first portions 211a1.

[0318] A plurality of first parts 211a1 and a plurality of second parts 211a2 may be arranged (or connected) in the same plane, and therefore, the vibration component 211a according to another embodiment of the present disclosure may be a single-layer film type. Therefore, the vibration component 211 (or the vibration generating component 210, or the first vibration device 201 and the second vibration device 202, or the vibration device 200) including the vibration layer 211a according to another embodiment of the present disclosure may vibrate through the first part 211a1 having vibration characteristics, and may be bent into a curved shape through the second part 211a2 having flexibility.

[0321] Each of the plurality of first portions 211a3 may be arranged to be spaced apart from each other along each of the first direction X and the second direction Y. For example, each of the plurality of first portions 211a3 may have a hexahedral shape of the same size and may be arranged in a grid shape, but the embodiments of the present disclosure are not limited thereto. For example, each of the plurality of first portions 211a3 may have a circular plate, an elliptical plate, or a polygonal plate having the same size as each other, but the embodiments of the present disclosure are not limited thereto.

[0322] Each of the plurality of first portions 211a3 may be the same as that referred to above. Fig.13 The described first portion 211 a 1 of the vibration layer 211 a are substantially the same, and thus, a repeated description thereof may be omitted.

The second portion 211a4 may be configured to fill a gap between two adjacent first portions 211a3, or to be adjacent to each of the plurality of first portions 211a3, or to be configured to surround each of the plurality of first portions 211a3, and thus, the second portion 211a4 may be connected to or attached to the first portion 211a3 adjacent thereto. The second portion 211a4 may be similar to the first portion 211a3 described above with reference to Fig.13 The second portion 211a2 of the description is substantially the same, and therefore, a repeated description thereof may be omitted.

A second surface of each of the plurality of first portions 211a3 and second portions 211a4 may be commonly connected to the second electrode layer 1311c.

[0325] A plurality of first parts 211a3 and second parts 211a4 may be arranged (or connected) in the same plane, and therefore, the vibration layer 211a according to another embodiment of the present disclosure may be a single-layer film type. Therefore, the vibration component 211 (or the vibration generating component 210, or the first vibration device 201 and the second vibration device 202, or the vibration device 200) including the vibration layer 211a according to another embodiment of the present disclosure may vibrate through the first part 211a3 having vibration characteristics, and may be bent into a curved shape through the second part 211a4 having flexibility.

[0327] Reference Figure 2 , Figure 8 and Fig.15 , the vibration device 200 according to another embodiment of the present disclosure may include more than two vibration generating components 210-1 and 210-2. For example, the vibration device 200 may include a first vibration generating component 210-1 and a second vibration generating component 210-2.

[0328] The first vibration generating component 210-1 and the second vibration generating component 210-2 may overlap or stack each other to shift (or drive or vibrate) in the same direction to maximize the amplitude displacement of the vibration device 200 or the amplitude displacement of the vibration member. For example, the second vibration generating component 210-2 may be stacked on the first vibration generating component 210-1. For example, the first vibration generating component 210-1 and the second vibration generating component 210-2 may have substantially the same size, but the embodiments of the present disclosure are not limited thereto. For example, the first vibration generating component 210-1 and the second vibration generating component 210-2 may have substantially the same size within the error range of the manufacturing process, but the embodiments of the present disclosure are not limited thereto. Therefore, the first vibration generating component 210-1 and the second vibration generating component 210-2 may maximize the amplitude displacement of the vibration device 200 and / or the amplitude displacement of the vibration member.

[0329] According to an embodiment of the present disclosure, any one of the first vibration generating component 210-1 and the second vibration generating component 210-2 can be Figures 2 to 8 The connection member 150 is shown connected or coupled to the vibration member 100. For example, the first vibration generating part 210-1 may be connected or coupled to the vibration member 100 through the connection member 150.

[0330] Each of the first vibration generating part 210 - 1 and the second vibration generating part 210 - 2 may be the same as that described above with reference to Figures 10 to 12 The vibration device 200 or the vibration component 211 described is the same or substantially the same, and therefore, the same reference numerals refer to the same elements and their repeated descriptions may be omitted. For example, each of the first vibration generating component 210-1 and the second vibration generating component 210-2 may include a vibration component 211 and a cover member 213.

[0331] The vibration device 200 according to another embodiment of the present disclosure may further include an intermediate member 203 .

[0332] The intermediate member 203 may be arranged or connected between the first vibration generating component 210-1 and the second vibration generating component 210-2. As one embodiment of the present disclosure, the intermediate member 203 may be arranged or connected between the second adhesive layer 213c of the first vibration generating component 210-1 and the first cover member 213a of the second vibration generating component 210-2. As another embodiment of the present disclosure, the intermediate member 203 may be arranged or connected between the second cover member 213d of the first vibration generating component 210-1 and the first cover member 213a of the second vibration generating component 210-2. For example, the intermediate member 203 may be an intermediate adhesive member, an adhesive member, or a connecting member, but embodiments of the present disclosure are not limited thereto.

[0333] According to an embodiment of the present disclosure, the intermediate adhesive member 203 may be configured as a material including an adhesive layer, and the adhesive layer has good adhesive force or adhesion relative to each of the first vibration generating component 210-1 and the second vibration generating component 210-2. For example, the intermediate adhesive member 203 may include a foam pad, a double-sided tape, a double-sided foam tape, a double-sided foam pad, a double-sided adhesive tape or an adhesive, etc., but the embodiments of the present disclosure are not limited thereto. For example, the adhesive layer of the intermediate adhesive member 203 may include epoxy resin, acrylic acid, silicone resin or polyurethane, but the embodiments of the present disclosure are not limited thereto. For example, the adhesive layer of the intermediate adhesive member 203 may include a urethane-based material (or substance) having a relatively ductile property. Therefore, the vibration loss caused by the displacement interference between the first vibration generating component 210-1 and the second vibration generating component 210-2 can be reduced or minimized, or each of the first vibration generating component 210-1 and the second vibration generating component 210-2 can be freely displaced (or vibrated or driven).

[0334] The vibration device 200 according to another embodiment of the present disclosure may include a first vibration generating component 210-1 and a second vibration generating component 210-2 that are stacked (or piled up or overlapped) to vibrate (or shift or drive) in the same direction, and thus, the displacement amount or amplitude displacement can be maximized or increased. Therefore, the displacement amount (or bending force or driving force) or amplitude displacement of the vibration member 100 can be maximized or increased, thereby further enhancing the sound characteristics and / or sound pressure level characteristics of the bass band.

[0335] Fig.16 Sound output characteristics of each of a device according to one embodiment of the present disclosure and a device according to an experimental example are shown.

[0336] The sound output characteristics can be measured by a sound measuring device in an anechoic chamber closed in all directions. The sound analysis device can be configured to include a sound card that can send sound to a control personal computer (PC) or receive sound from a control personal computer (PC), an amplifier that can amplify the signal generated from the sound card and transfer the amplified signal to a vibration device, and a microphone that can collect the sound generated by the display panel based on the drive of the vibration device. For example, the microphone is set at a distance of 50cm from the front surface of the vibration device on the display panel. The sound collected by the microphone can be input to the control PC through the sound card, and the control program can check the input sound to analyze the sound output characteristics of the vibration device. For example, the frequency response characteristics of the frequency range of 100Hz to 20kHz can be measured by a pulse program. The measurement method of the sound output characteristics does not limit the content of the present disclosure.

[0337] Fig.16 The dashed line and the thin solid line represent the sound output characteristics of the device according to the experimental example. The dashed line represents the sound output characteristics when no pad member is configured in the vibration device. The thin solid line represents the sound output characteristics when a pad member is configured in the center part of the vibration device. Fig.16 The thick solid line represents an embodiment of the present disclosure. Figure 3 and Figure 4 The sound output characteristics of the device. Fig.16 , the horizontal axis represents the frequency in Hertz (Hz), and the vertical axis represents the sound pressure level (SPL) in decibels (dB).
