Description

[Technical field]

[0001] The present disclosure relates to devices, including but not limited to devices and transport devices including the same. [Background technology]

[0002] The device includes a separate speaker or audio device to provide sound. When the speaker is arranged in the device, the speaker occupies the space of the device. Therefore, there is a problem that the design and spatial arrangement of the device are restricted.

[0003] The speaker applied to the device may be, for example, an actuator including a magnet and a coil. However, when an actuator is applied to a device, the device has a drawback in that the device is thick. Therefore, a piezoelectric element that can realize a thin thickness is attracting attention.

[0004] Piezoelectric elements are easily damaged by external impact due to their brittle characteristics, which results in low reliability in sound reproduction. In addition, when a speaker such as a piezoelectric element is applied to a flexible device, the brittle characteristics of the piezoelectric element can cause damage. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present specification have recognized the above problems and conducted various research and experiments to prevent damage to a piezoelectric element due to impact when attaching a vibration element to a device, etc., and to improve sound quality and / or acoustic characteristics. Through various experiments, they have invented a device and a transportation device including a new vibration device that can reduce damage to a piezoelectric element due to impact when attaching a vibration element to a device, etc., and can improve sound quality and / or acoustic characteristics.

[0017] Throughout the drawings and detailed description, unless otherwise stated, the same drawing numerals should be understood to refer to the same components, features and structures. The relative size and depiction of these elements may be exaggerated for clarity, explanation and convenience. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Reference will now be made in detail to the embodiments of the present specification, examples of which may be illustrated in the accompanying drawings. In the following description, if a specific description of well-known functions or configurations unnecessarily obscures the gist of the present specification, the specific description may be omitted for the sake of brevity. The progression of steps and / or operations described is exemplary, but the order of steps and / or operations is not limited to those described herein and may be modified, except for steps and / or operations that necessarily occur in a particular order. Unless otherwise specified, the same reference numerals may generally refer to similar components even if they are illustrated in different drawings. In one or more embodiments, identical components (or components having the same name) in different drawings may have the same or substantially the same functions and characteristics, unless otherwise specified. The names of the respective components used in the following description are selected for convenience and may differ from the actual products.

[0019] The advantages and features of the present specification and methods for achieving them will become apparent from the following detailed description of various embodiments with reference to the accompanying drawings. However, the present specification is not limited to the embodiments disclosed below, and may be embodied in various different forms, and the embodiments are provided solely for the purpose of completing the disclosure of the present specification and fully conveying the scope of the technical ideas of the present specification to those skilled in the art to which the technical ideas of the present specification belong.

[0020] The shapes, sizes, areas, ratios, angles, numbers, etc. disclosed in the drawings for explaining the embodiments of this specification are merely illustrative, and the present specification is not limited to the details shown in the drawings.

[0021] When the terms "comprise", "have", "consist", "comprise", "formed", etc. are used in this specification, other parts can be added unless "only" or "only" is used. The terms used in this specification are used only to describe a particular embodiment and are not intended to limit the scope of the specification. The terms used in this specification are used only to describe an exemplary embodiment and are not intended to limit the scope of the specification. Terms expressing elements in the singular include the plural unless otherwise expressly stated. An "embodiment" may be an illustrative example. Any implementation described in the "embodiment" or "example" described in this specification should not necessarily be construed as preferred or advantageous over other implementations.

[0022] In one or more embodiments, components, features, or corresponding information (e.g., levels, ranges, dimensions, sizes, etc.) may be interpreted as including an error or tolerance range even if an explicit description of these error or tolerance ranges is not provided. The error or tolerance range may be caused by various factors (e.g., process factors, internal or external impacts, noise, etc.).

[0023] In the case of a description of a location relationship, when a location relationship is described between two parts using words such as "on or over," "on top," "under or below," "at the bottom," "near," "adjacent to," "beside," or "next to," one or more other parts may be located between the two parts, unless "just," "immediately(ly)," "close(ly)," or "direct(ly)" is used. For example, when structures are described as being located "above or over," "on top," "under or below," "on bottom," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures touch each other and have a third structure disposed between them. For example, when structures are described as being located "above or over," "on top," "under or below," "on bottom," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures touch each other and have a third structure disposed between them. Additionally, "front", "back", "back", "left", "right", "top", "bottom", "downward", "upward", "top", "bottom", "column", "row", "vertical", "horizontal", etc. refer to any frame of reference.

[0024] In the case of descriptions of temporal relationships, when the temporal sequence is described using "after," "subsequent," "next," "before, preceding, or prior to," etc., consecutive or non-consecutive cases can also be included, since "just," "immediately," or "directly" are not used.

[0025] Although the terms "first", "second", etc. are used to describe various components, these components are not limited to these terms. These terms are used only to distinguish one component from another component. Thus, a first component referred to below may also be a second component within the technical spirit of this specification. Furthermore, the first element, the second element, etc. may be named arbitrarily according to the convenience of a person skilled in the art without departing from the scope of this specification. Terms such as "first", "second", etc. may be used to distinguish components from each other, but the function or structure of the component is not limited by the ordinal number before the component or the name of the component.

[0026] In describing components of this specification, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are used to distinguish the components from other components, and are not used to define the nature, basis, order, or number of the components.

[0027] When a component or layer is described as being "connected," "bonded," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other components, but that other components or layers may be "disposed" or "interpodated" between each component that may be indirectly connected or connected unless specifically and explicitly stated.

[0028] When a component or layer is described as being in "contact with" or "overlapping" another component or layer, it should be understood that the component may be in direct contact with or overlaid on the other component or layer, but one or more other components or layers may be "disposed" or "interpodded" between each component or layer that may be in indirect contact or overlaid unless otherwise expressly described. For example, for purposes of this specification, terms such as "overlap" and "overlapping" should be understood as "overlapping, electrically and / or physically connected" by, for example, surface-to-surface connection, and "overlapping, electrically and / or physically connected" by, for example, surface-to-surface connection.

[0029] Terms such as "line" or "direction" should not be construed solely in terms of a geometric relationship in which the respective lines or directions are aligned or perpendicular to one another, but can refer to lines or directions that have a broader orientation within which the components of this specification can functionally operate.

[0030] The term "at least one" should be understood to include all possible combinations of one or more of the associated items. For example, the meaning of "at least one of the first, second, and third items" may include only any combination of the first, second, and third items, and not just combinations of items presented from two or more of the first, second, or third items.

[0031] The phrase "first component", "second component" and / or "third component" should be understood as one of the first, second and third components or any or all combinations 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 some combination of A, B and C, or all of A, B and C. Furthermore, the phrase "component A / component B" should be understood as component A and / or component B.

[0032] In one or more embodiments, the terms "between" and "in" may be used interchangeably for convenience only, unless otherwise noted. For example, the phrase "between multiple components" may also be understood as "among multiple components." In other embodiments, the phrase "among 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.

[0033] In one or more embodiments, the term "different from" may be understood to mean that any element is different from the other element.

[0034] In one or more embodiments, the terms "one or more of" and "one or more of" may be used interchangeably for convenience only, unless otherwise specified. For example, the term "one or more of" can also be understood as "one or more of." For example, the term "one or more of" can also be understood as "one or more of."

[0035] In the present specification, the term "apparatus" may include a display device such as a liquid crystal display (LCD) or an organic light emitting display (OLED) including a display panel and a driver for driving the display panel. In addition, in the present specification, the term "apparatus" may also include a set electronic apparatus or set device such as a notebook computer, a television, a computer monitor, an automotive apparatus or other forms of a vehicle, which is a complete product or final product including an LCD or an OLED, and a mobile electronic apparatus such as a smartphone or an electronic pad.

[0036] Therefore, the device in this specification can include a display device itself such as an LCD or OLED, and a set device that is an application product or end-user device that includes an LCD or OLED.

[0037] In one or more embodiments of the present specification, an LCD or OLED composed of a display panel and a driver may be referred to as a "display device," and an electronic device as a completed product including the LCD or OLED may be referred to as a "set device." For example, the display device may include a display panel such as a liquid crystal display panel or an organic light emitting display panel, and a source printed circuit board (PCB) that is a controller for driving the display panel. The set device may further include a set PCB (or control PCB) that is a set controller electrically connected to the source PCB and drives the entire set device.

[0038] The display panel used in one or more embodiments of the present specification may be a display panel of any shape, such as a liquid crystal display panel, an organic light-emitting display panel, and an electroluminescent display panel, and the embodiments of the present specification are not limited thereto. For example, the display panel may be a display panel that can generate sound by being vibrated by a vibration device according to the embodiments of the present specification. The display panel applied to the device or display device according to the embodiments of the present specification is not limited to the shape or size of the display panel.

[0039] According to one or more embodiments of the present specification, when the display panel is a liquid crystal display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and a plurality of pixels formed at each of the intersection regions of the gate lines and the data lines.

[0040] When the display panel is an organic light emitting display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and a plurality of pixels formed at each of the intersection regions of the gate lines and the data lines. The display panel may include an array substrate including a thin film transistor, which is an element for selectively applying a voltage to each pixel, an organic light emitting device (OLED) layer on the array substrate, and a sealing substrate or encapsulation substrate disposed on the array substrate to cover the organic light emitting device layer. The sealing substrate may protect the thin film transistor and the organic light emitting device layer from external impact and prevent moisture or oxygen from penetrating into the organic light emitting device layer. The layer formed on the array substrate may include an inorganic light emitting layer, for example, a nano-sized material layer, and a quantum dot light emitting layer.

In one or more embodiments of the present specification, the components of each device according to various embodiments of the present specification may be operably combined or configured.

[0043] The terms used in this specification (including technical and scientific terms) may have the same meaning as that understood by a person having ordinary knowledge in the technical field to which this specification belongs. Furthermore, terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant technology, and should not be interpreted as idealized or overly formal unless otherwise specified.

[0044] Hereinafter, a vibration device according to various embodiments of the present specification, a vibration device, and a vehicle including the same will be described in detail with reference to the accompanying drawings. The reference numbers for components in each drawing may refer to similar components, although the same components may be illustrated in other drawings, unless otherwise specified. Furthermore, for convenience of explanation, the scale, dimensions, size, and thickness of the components illustrated in the drawings may have a scale, dimensions, size, and thickness different from the actual scale, dimensions, size, and thickness, and therefore are not limited to the scale, dimensions, size, and thickness illustrated in the drawings.

[0045] Figure 1 is a perspective view of an apparatus according to an embodiment of the present disclosure. Figure 2 is a diagram of an apparatus according to an embodiment of the present disclosure.

[0046] Referring to FIG. 1, a device 10 according to embodiments of the present disclosure can include a vibration element 200 .

[0047] The vibration element 200 may be configured to vibrate (or displace or be driven) by an applied drive signal (or electrical signal or voice signal) to vibrate (or displace) a vibration member, or to vibrate the display panel from the rear side of the display panel, and provide acoustic and / or haptic feedback to a user by the vibration of the display panel. For example, the vibration element 200 may be an active vibration member, a vibration generator, a vibrating structure, a vibrator, a vibration generating element, an acoustic generator, an acoustic element, an acoustic generating structure, or an acoustic generating element, but examples of the present specification are not limited thereto.

[0048] The vibration element 200 according to the embodiment of the present specification may include a piezoelectric material (or an electroactive material or a piezoelectric ceramic) having piezoelectric properties. The vibration element 200 may vibrate (or displace) itself or vibrate (or displace) a vibrating member or the like by vibration (or displacement) of the piezoelectric material due to a driving signal applied to the piezoelectric material. For example, the vibration element 200 may vibrate (or displace) by alternately repeating contraction and / or expansion due to the piezoelectric effect (or piezoelectric properties). For example, the vibration element 200 may vibrate (or displace) in the vertical direction (or thickness direction) (Z) by alternately repeating contraction and / or expansion due to the inverse piezoelectric effect of the piezoelectric structure. Thus, the displacement amount (or bending force or deflection force) or amplitude displacement of the vibration element 200 may be increased or maximized, and the embodiment of the present specification is not limited thereto. For example, the vibration element 200 according to the embodiment of the present specification may vibrate (or be mechanically displaced) in response to an electrical signal applied from the outside by including a piezoelectric ceramic having a perovskite-series crystal structure.

[0049] The vibration element 200 according to the embodiment of the present specification has an advantage of being thin compared to a coil-shaped acoustic device, but may easily break due to its brittle characteristics. To solve this problem, the vibrator 1 may be configured to be easy to handle in the assembly process and prevent damage to the vibration element 200.

[0050] The vibrator 1 according to the embodiment of the present specification may include a support member 100 and a vibration element 200. The vibration element 200 may be disposed on the support member 100. For example, the support member 100 may be disposed on the rear surface of the vibration element 200. For example, the support member 100 may support or protect the vibration element 200. This may prevent or minimize damage to the vibration element 200.

[0051] The vibrator 1 according to the embodiment of the present specification may further include a first connecting member 120 between the support member 100 and the vibration element 200. The vibrator 1 according to the embodiment of the present specification may include the support member 100, the vibration element 200, and the first connecting member 120.

[0052] The first connecting member 120 may be connected or coupled to any one of the first surface and the second surface different from (or opposite to) the first surface of the vibration element 200. For example, in the vibration element 200, the first surface may be the upper surface, the front surface, the top surface, or the front surface. In the vibration element 200, the second surface may be the lower surface, the back surface, the rear surface, the lower surface, or the back surface. For example, the first connecting member 120 may be a connecting member, a bonding member, an adhesive member, or a first adhesive member that may at least include a substance including an adhesive layer having excellent adhesion or adhesiveness to the vibration element 200, but the embodiments of the present specification are not limited thereto.

[0053] According to an embodiment of the present specification, the first connecting member 120 is disposed between the rear surface (or back surface) of the support member 100 and the vibration element 200, and the vibration element 200 can be connected or coupled to the back surface of the support member 100. For example, the vibration element 200 can be supported or disposed on the back surface of the support member 100 by being connected or coupled to the back surface of the support member 100 via the first connecting member 120.

[0054] The first connecting member 120 according to the embodiment of the present specification may include an adhesive layer (or a pressure-sensitive adhesive layer) having excellent adhesion or bonding strength. For example, the first connecting member 120 may be made of a material including an adhesive layer having excellent adhesion or bonding strength to each of the rear surface of the support member 100 and the vibration element 200. For example, the first connecting member 120 may include a foam pad, double-sided tape, double-sided foam pad, double-sided foam tape, adhesive, double-sided adhesive tape, double-sided adhesive foam pad, or adhesive sheet, and the embodiment of the present specification is not limited thereto. For example, when the first connecting member 120 includes an adhesive sheet (or adhesive layer), the first connecting member 120 may include only an adhesive layer or adhesive layer without a base member such as a plastic material.

[0055] The adhesive layer (or sticky layer) of the first connecting member 120 according to the embodiment of the present specification may include epoxy, acrylic, acryl-based polymer, silicone-based polymer, silicone, urethane-based polymer, or urethane, but the embodiment of the present specification is not limited thereto. The adhesive layer (or sticky layer) of the first connecting member 120 according to other embodiments of the present specification may include a heat-curable adhesive, a photo-curable adhesive, a pressure sensitive adhesive (PSA), an optically clear adhesive (OCA), an optically clear resin (OCR), or a heat-sealing adhesive (e.g., a heat-active type or a thermosetting type, etc.), but the embodiment of the present specification is not limited thereto. For example, the adhesive layer of the first connecting member 120 may include an acrylic-based substance (or material) having a relatively better adhesive strength and high hardness than a urethane material, so that the vibration of the vibration element 200 may be effectively transmitted to the vibration member 20.

[0056] The adhesive layer of the first connecting member 120 may further include an additive such as a tackifier, a wax component, or an antioxidant, but the embodiments of the present specification are not limited thereto. The additive can prevent the first connecting member 120 from being separated (or peeled off) from the support member 100 due to the vibration of the vibration element 200. For example, the tackifier may be a rosin derivative, the wax component may be paraffin wax, and the antioxidant may be a phenol-based antioxidant such as thioester, but the embodiments of the present specification are not limited thereto.

[0057] 1, the device 10 according to the embodiment of the present specification may further include a first protective part 300. The vibrator 1 according to the embodiment of the present specification may include a support member 100, a vibration element 200, a first connecting member 120, and / or a first protective part 300.

[0058] The first protective part 300 can protect the vibration element 200. The first protective part 300 can include one or more of a metal material or a non-metal material (or a composite non-metal material). For example, the first protective part 300 can include one or more of a metal material, a plastic, a fiber, and a wood, and the embodiment of the present specification is not limited thereto. For example, the first protective part 300 can be an enclosure, a protective part, a protective member, or a cover, and the embodiment of the present specification is not limited thereto.

[0059] Referring to FIG. 1, a vibrator 1 according to an embodiment of the present specification may include a support member 100, a vibration element 200, a first connecting member 120, and / or a first protective part 300. The vibrator 1 may be a vibration generator, a vibration module, a vibration generating module, or a vibration generating device, and the embodiment of the present specification is not limited thereto. When configured with a module (or device) for protecting one vibrator 1 or vibration element 200, damage to the vibration element 200 due to warping or external impact can be prevented, so that handling during an assembly process may be easy. The inventor of the present specification recognized that while it is easy to attach the vibrator 1 to a vibration member composed of a flat portion, there is a problem in that it is difficult to attach it to a vibration member including a curved portion. And, when the vibration member is an exterior material and / or an interior material of a vehicle (or a transportation device), the vibrator 1 may be attached to the exterior material and / or the interior material by a double-sided adhesive or the like. Although double-sided adhesives can be used to simplify the attachment process and allow repairs, the adhesive strength or bonding strength of the double-sided adhesive varies depending on the material and shape of each part (or vehicle structure) of a vehicle (or transportation device), which can cause problems with the adhesive strength or bonding strength of the vibrator 1 attached (placed or mounted) to the exterior and / or interior material of the vehicle (or transportation device). Therefore, through several experiments, the inventors of the present specification have invented a new device that can be attached to a vibration member including a curved portion or to the exterior and / or interior material of a vehicle (or transportation device), which will be described below.

[0060] Referring to FIG. 1, the device 10 according to the embodiments herein may further include a coupler 400 .

[0061] The coupler 400 can accommodate (or insert) the vibrator 1. For example, the coupler 400 can accommodate the vibration element 200. For example, the coupler 400 can accommodate the support member 100 and the vibration element 200. The coupler 400 can be a coupler, a linker, a coupling, a coupling means, a connecting member, or a coupling member, and the examples of the present specification are not limited thereto. The coupler 400 can be made of an extrusion material, and the examples of the present specification are not limited thereto. For example, the coupler 400 can be made of an extrusion material including a plastic or a styrene material, and the examples of the present specification are not limited thereto. For example, the styrene material can be an ABS material. The ABS material can be acrylonitrile, butadiene, and styrene.

[0062] 2, the device 10 according to the embodiments herein may further include a vibration member 20. The vibrator 1 may be in the vibration member 20.

[0063] The device 10 according to the embodiments of the present specification may further include a second connecting member 105. For example, the coupler 400 may be connected or coupled to the vibrator 1 by the second connecting member 105.

[0096] The vibration element 200 or the vibrator 1 may be disposed on the rear surface of the vibration member 20. For example, the vibration element 200 or the vibrator 1 may vibrate the vibration member 20. For example, the vibration element 200 may be realized on the rear surface of the vibration member 20 so as to directly vibrate the vibration member 20. For example, the vibration element 200 may provide the user with sound and / or haptic feedback based on the vibration of the vibration member 20 by vibrating the vibration member 20 on the rear surface of the vibration member 20. For example, the vibration member 20 may output sound by the vibration of the vibration element 200. The vibration element 200 may output sound by using the vibration member 20 as a diaphragm. For example, the vibration element 200 may output sound to the front surface of the vibration member 20 by using the vibration member 20 as a diaphragm.

[0097] According to an embodiment of the present specification, the vibrating element 200 can vibrate the display panel by vibrating according to a vibration drive signal synchronized with an image displayed on the display panel, which is the vibrating member 20. According to another embodiment of the present specification, the vibrating element 200 can vibrate the display panel by vibrating according to a haptic feedback signal (or tactile feedback signal) synchronized with a user's touch on a touch panel (or a touch sensor layer) disposed on or built into the display panel. In this way, the display panel can vibrate according to the vibration of the vibrating element 200 to provide at least one of audio and haptic (or tactile) feedback to the user (or viewer), and the embodiment of the present specification is not limited thereto.

[0098] The vibration element 200 or vibrator 1 according to the embodiments of the present specification may be realized in a size corresponding to the vibration member 20 or the display area of ​​the display panel. The size of the vibration element 200 may be 0.9 to 1.1 times the size of the vibration member 20 or the display area, but the embodiments of the present specification are not limited thereto. For example, the size of the vibration element 200 may be the same as or smaller than the size of the vibration member 20 or the display area. For example, the size of the vibration element 200 may be the same as or approximately the same as the display area of ​​the vibration member 20 or the display panel, so that it can cover most of the area of ​​the vibration member 20 or the display panel, and the vibration generated from the vibration element 200 can vibrate the entire area of ​​the vibration member 20 or the display panel, so that the sense of sound localization is high and the satisfaction of the user can be improved. In addition, since the contact area (or panel coverage) between the vibrating member 20 or the display panel and the vibrating element 200 can be increased and the vibration area of ​​the vibrating member 20 or the display panel can be increased, the mid-low frequency band sound generated by the vibration of the vibrating member 20 or the display panel can be improved. In addition, the vibrating element 200 applied to a large device (large display device) can vibrate the entire large (or large area) vibrating member 20 or the display panel, so that the sense of localization of the sound caused by the vibration of the vibrating member 20 or the display panel can be further improved and improved sound effects can be realized.

[0099] The vibration device 200 according to the embodiment of the present specification may be realized in a film shape, and since the vibration element 200 is realized in a film shape, it can have a thickness thinner than the vibration member 20 or the display panel, so that an increase in the thickness of the device can be minimized by the arrangement of the vibration element 200. For example, the vibration element 200 can use the vibration member 20 or the display panel as an acoustic diaphragm. For example, the vibration element 200 can be expressed as a vibration device, a vibration generating device, a displacement device, an acoustic device, an acoustic generating module, an acoustic generating device, a film actuator, a film type piezoelectric composite actuator, a film speaker, a film type piezoelectric speaker, a piezoelectric element, a piezoelectric vibrating part, a piezoelectric vibrating layer, a piezoelectric driving part, a piezoelectric structure, or a film type piezoelectric composite speaker, and the embodiment of the present specification is not limited thereto.

[0100] In another embodiment of the present specification, the device 10 or the vibration device may be applied to a non-display panel instead of a display panel, without being disposed on the rear surface of the display panel. For example, the non-display panel may include one or more of wood, plastic, glass, metal, cloth, fiber, rubber, paper, mirror, carbon, leather, interior materials of vehicles, interior materials of building ceilings, and interior materials of aircraft, and the embodiments of the present specification are not limited thereto. In this case, the non-display panel may be applied to a diaphragm, and the vibration element 200 may vibrate the non-display panel to output sound.

[0101] In other embodiments of the present specification, the device 10 or the vibration device may be applied to realize an audio device, an audio output device, a sound bar, an audio system, an audio device for a transportation device, an audio output device for a transportation device, or a sound bar for a transportation device.

For example, the transportation device may include a vehicle, a train, a ship, or an aircraft, and the embodiments of the present specification are not limited thereto. In addition, the device 10 or the vibration device may realize analog signage or digital signage such as an advertising billboard, a poster, or a guide board.

[0102] The device 10 or vibration device according to the embodiments of the present specification may be disposed on the back surface of the vibration member 20 or the display panel so as to overlap with the display area of ​​the vibration member 20 or the display panel. For example, the device 10 or vibration device may overlap with more than half of the vibration member 20 or with more than half of the display area of ​​the display panel. According to other embodiments of the present specification, the device 10 or vibration device may overlap with the entire vibration member 20 or the entire display area of ​​the display panel. For example, the device 10 or vibration device may overlap with 20%, 30%, 40%, 60%, 70%, 80%, or 90% of the entire area of ​​the vibration member 20 or the display area of ​​the display panel, and the embodiments of the present specification are not limited thereto.

[0103] According to another embodiment of the present specification, a plate may be further disposed on the vibration element 200. For example, the plate may be disposed on the front and / or rear surface of the vibration element 200. The plate may include a metal material, or may include any one or more of a single non-metallic material or a composite non-metallic material among wood, rubber, plastic, glass, fiber, cloth, paper, mirror, carbon, and leather, and the embodiment of the present specification is not limited thereto. For example, each of the vibration element 200 and the plate may have the same size, and the embodiment of the present specification is not limited thereto.

[0104] The plate according to the embodiment of the present specification can reduce the lowest resonance frequency (or the lowest natural frequency) of the vibration element 200 by increasing the weight of the vibration element 200. Therefore, the vibration element 200 can vibrate at a relatively low frequency due to the reduction in the lowest resonance frequency (or the lowest natural frequency) caused by the increase in weight of the plate. This can improve the acoustic characteristics and / or sound pressure characteristics of the low frequency band generated by the vibration of the vibration element 200, and the flatness of the sound pressure characteristics can be increased or improved. For example, the flatness of the sound pressure characteristics can be the magnitude of deviation between the maximum sound pressure and the minimum sound pressure. For example, the plate can be a resonating pad, a mass member, a weight member, an acoustic flattening member, a support plate, a rigid plate, a transmission plate, an intermediate plate, or a vibration transmission plate, and the embodiment of the present specification is not limited thereto. For example, the low frequency band can be 200 Hz or less, or 300 Hz or less, or 400 Hz or less, or 500 Hz or less, but the embodiment of the present specification is not limited thereto, and can be 3 kHz or less.

[0105] When an AC voltage is applied to the vibration element 200 according to the embodiment of the present specification, the vibration element 200 can vibrate by alternately repeating contraction and / or expansion due to the inverse piezoelectric effect, and the vibration can be used to vibrate the vibration member 20 or the display panel. For example, the vibration element 200 can vibrate the display panel by vibrating with a voice signal synchronized with an image displayed on the display panel. As another embodiment of the present specification, the vibration element 200 can vibrate the display panel by vibrating with a haptic feedback signal (tactile feedback signal) synchronized with a user's touch on a touch panel (or a touch sensor layer) disposed on the display panel or built into the display panel. As a result, the display panel can vibrate due to the vibration of the vibration element 200 to provide at least one of sound and haptic feedback to the user (or viewer).

[0106] Therefore, the device 10 or vibration device according to the embodiment of the present specification can output the sound generated by the vibration of the vibrating member 20 or the display panel due to the vibration of the vibrating element 200 to the front of the vibrating member 20 or the display panel. And, since the device 10 according to the embodiment of the present specification can vibrate most of the area of ​​the vibrating member 20 (or the display panel) by the film-shaped vibrating element 200, the sound pressure characteristics and the sense of sound localization due to the vibration of the vibrating member 20 (or the display panel) can be further improved.

[0107] Referring to FIG. 2, the first protective part 300 may be connected or coupled to the rear surface of the vibration element 200 (when the surface of the vibration element 200 facing the vibration member 20 is the upper surface) so as to cover the vibration element 200. For example, the first protective part 300 may be connected or coupled to the rear surface of the vibration element 200 via a connecting member (or a coupling member). The first protective part 300 may form a sealed space that covers or surrounds the vibration element 200. For example, the first protective part 300 may be an enclosure, a sealing member, a sealing cap, a sealing box, or a sound box, although the embodiments of the present specification are not limited thereto. The sealed space may be a gap space, an air gap, a vibration space, an acoustic space, or a sound box, although the embodiments of the present specification are not limited thereto.

[0108] The first protective part 300 according to the embodiment of the present specification may further include one or more holes 310. The one or more holes 310, which may be referred to as a communication part, may communicate (or connect) the sealed or sealed space between the first protective part 300 and the vibration element 200 with the outside of the device 10.

[0109] The one or more holes 310 of the first protective unit 300 may be arranged in a predetermined area of ​​the first protective unit 300 to reduce air pressure in a gap space in the device or vibration device. For example, the one or more holes 310 may be arranged to have a certain interval. The one or more holes 310 may be configured to correspond to the size of the vibration element 200 or the vibration device. The one or more holes 310 may overlap with the vibration element 200 or the vibration device. For example, the one or more holes 310 may have a size smaller than the size of the vibration element 200. For example, one or more holes 310 that are different from each other may be arranged in a region where the vibration element 200 is not arranged, rather than in a region where the vibration element 200 is arranged. For example, the one or more holes 310 of the first protective unit 300 may be arranged to be different from the center of the vibration element 200 to the edge. For example, the size of the one or more holes 310 may be different from the center of the vibration element 200 to the edge.

[0110] According to the embodiment of the present specification, the one or more holes 310 of the first protective part 300 can expand the band of the bass band as the air pressure in the gap space is reduced, and therefore the acoustic characteristics of the bass band can be improved. For example, as the pressure (or air pressure) in the gap space is reduced by the one or more holes 310, the displacement (or bending force) of the vibration element 200 disposed between the vibration member 20 or the display panel and the first protective part 300 can be increased, thereby expanding the band of the bass band, and further improving the acoustic characteristics and / or sound pressure characteristics of the bass band. If the one or more holes 310 are not disposed in the first protective part 300, the air pressure in the gap space increases due to the sound waves or sound generated by the vibration of the vibration element 200, and the acoustic characteristics of the bass band can be reduced. In addition, if the one or more holes 310 are disposed in the first protective part 300, the vibration device 200 can vibrate more stably, and therefore the sound quality and acoustic characteristics of the sound can be improved.

[0111] According to the embodiment of the present specification, by forming one or more holes 310 in the first protective part 300, even if sound waves or sounds are generated by vibration of the vibration element 200 or the vibration device, air can be discharged through one or more holes 310, so that the air pressure in the gap space can be reduced. As a result, the frequency band of the bass band can be expanded, and the acoustic characteristics of the bass band can be improved.

[0112] With reference to FIG. 2, the coupler 400 may further include at least one or more coupling portions 404 .

The alignment member may be configured as an alignment key, an alignment scale, or an alignment groove, and the embodiment of the present specification is not limited thereto. For example, the alignment member may adjust or adjust the alignment position of the coupler 400 and the vibrator 1. For example, the alignment member may visually check whether the coupler 400 and the vibrator 1 are assembled, thereby improving the reliability of the device 10 or the vibration device.

[0115] Although the vibrator 1 according to one or more embodiments of the present specification is shown to include, for example, a laminated structure of the vibration element 200, the first connecting member 120, the support member 100, and the second connecting member 105 (or further including the first protective part 300), the embodiments of the present specification are not limited thereto.

The receiving portion 407, the first surface 401, at least one or more grooves 406, and at least one or more coupling portions 404 are substantially the same or similar to those described with reference to FIGS. 4 to 6, and therefore the description here may be omitted or may be briefly described. In addition, the description of the rear surface of the connector 400 described with reference to FIG. 6 may also be applied in the same or similar manner to FIG. 7.

[0141] FIG. 8 shows an apparatus according to another embodiment of the present disclosure.

[0142] 8, a device according to another embodiment of the present specification may include a vibration member 20, a vibrator 1, and a coupler 400. The description of the vibration member 20, the vibrator 1, and the coupler 400 is substantially the same or similar to the description with reference to FIGS. 1 to 7, so the same reference numerals are used therefor, and the duplicated description thereof may be omitted or simplified.

[0143] The vibration member 20 according to the embodiment of the present specification may include at least one or more curved portions. For example, the vibration member 20 may include at least one or more flat portions and at least one or more curved portions. The at least one or more curved portions may be disposed adjacent to the at least one or more flat portions, but the embodiment of the present specification is not limited thereto. Thereby, the coupling device 400 may be configured along the shape of the at least one or more curved portions of the vibration member 20. For example, the coupling device 400 may be disposed or configured corresponding to the shape of the at least one or more curved portions of the vibration member 20. For example, the coupling device 400 may have at least one or more curved portions 408 corresponding to the shape of the at least one or more curved portions of the vibration member 20. In other words, the coupling device 400 may be configured to be completely attached to the vibration member 20, and may be configured to flatten or planarize the at least one or more curved portions of the vibration member 20, so that the vibration element 200 can be easily attached to the vibration member 20 and the vibration element 200 disposed thereon can be prevented from bending or curving. At least one or more curved surface portions 408 may be disposed on a first surface of the coupler 400 and may have a concave shape, and examples herein are not limited thereto. For example, at least one or more curved surface portions 408 may have a concave shape toward the vibration member 20, and examples herein are not limited thereto. For example, when the vibration member 20 is an exterior and / or interior material of a vehicle, the exterior and / or interior material of the vehicle may include at least one or more curved surface portions. Since the coupler 400 including at least one or more curved surface portions 408 may be coupled or disposed along the shape of the vibration member 20, or the exterior and / or interior material of the vehicle, the vibrator 1 may be easily coupled or attached to the vibration member 20 including at least one or more curved surface portions, or the exterior and / or interior material of the vehicle, by the coupler 400 without reducing the adhesion or bonding force of the vibrator 1.

[0144] According to an embodiment of the present specification, the coupler 400 may be configured to include at least one or more curved surface portions 408 according to the shape of the exterior and / or interior material of the vehicle, and the coupler 400 and the exterior and / or interior material of the vehicle may be attached by a connecting member to configure an integrated vibration device.

Since the attachment position of the vibrator 1 may be guided by the coupler 400, deviations in the acoustic characteristics of the vibrator 1 may be reduced or minimized. According to an embodiment of the present specification, the coupler 400 may include at least one or more coupling portions 404, so that the vibrator 1 may be coupled or fixed to the coupler 400 without floating.

The at least one or more curved portions 409 may have a streamlined or boat shape, and the embodiment of the present specification is not limited thereto. For example, when the vibration member 20 is an exterior material and / or an interior material of a vehicle, the exterior material and / or the interior material of the vehicle may include at least one or more curved portions. Since the coupler 400, which includes at least one or more curved portions 409, can be coupled or positioned along the shape of the vibration member 20, or the exterior and / or interior materials of the vehicle, the vibrator 1 can be easily coupled or attached to the vibration member 20, which includes at least one or more curved portions 409, or the exterior and / or interior materials of the vehicle, by the coupler 400.

Since the integrated vibration device may be attached to the first surface 401 of the coupler 400, the process of attaching the vibration device to the vibration member 20 may be simplified. Since the attachment position of the vibrator 1 may be guided by the coupler 400, deviations in the acoustic characteristics of the vibrator 1 may be reduced or minimized. According to an embodiment of the present specification, the coupler 400 may include at least one or more protrusions 402 and / or at least one or more coupling portions 404, so that the vibrator 1 may be coupled or fixed to the coupler 400 without floating.

[0156] 11 to 13, the vibration element 200 according to the embodiments of the present specification may be represented as an active vibration member, a vibration device, a flexible vibration device, a flexible vibration structure, a flexible vibrator, a flexible vibration generating element, a flexible vibration generator, a flexible acoustic device, a flexible acoustic element, a flexible acoustic generating element, a flexible acoustic generator, a flexible actuator, a flexible speaker, a flexible type piezoelectric speaker, a film actuator, a film type piezoelectric composite actuator, a film speaker, a film type piezoelectric speaker, or a film type piezoelectric composite speaker, etc., and the embodiments of the present specification are not limited thereto.

[0157] The vibration element 200 according to the embodiment of the present specification may include a vibration part 511. The vibration part 511 may include a vibration layer 511a, a first electrode layer 511b, and a second electrode layer 511c.

[0158] The vibrating part 511 according to the embodiment of the present specification may include a piezoelectric vibrating part. The vibrating layer 511a may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the piezoelectric material may have a characteristic that a potential difference is generated by dielectric polarization due to a change in the relative positions of positive (+) ions and negative (-) ions when a pressure or twist phenomenon acts on a crystal structure due to an external force, and vibration is generated by an electric field due to an applied voltage. For example, the vibrating layer 511a may be expressed as a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a piezoelectric material part, an electroactive part, a piezoelectric structure, a piezoelectric composite layer, a piezoelectric composite, or a piezoelectric ceramic composite, and the embodiment of the present specification is not limited thereto. The vibrating layer 511a may be made of a transparent, semitransparent, or opaque piezoelectric material, so the vibrating layer 511a may be transparent, semitransparent, or opaque.

[0159] 13, the vibration unit 511 according to the embodiment of the present specification may include a plurality of inorganic material parts and an organic material part between the plurality of inorganic material parts. For example, each of the plurality of inorganic material parts may have a piezoelectric characteristic. For example, each of the plurality of inorganic material parts may be a first part 511a, and the organic material part may be a second part 511a2. For example, the vibration layer 511a may include a plurality of first parts 511a1 and a plurality of second parts 511a2. For example, the plurality of first parts 511a1 and the plurality of second parts 511a2 may be alternately and repeatedly arranged along the second direction (Y) (or the first direction (X)). For example, the first direction (X) may be the horizontal direction of the vibration layer 511a, and the second direction (Y) may be the vertical direction of the vibration layer 511a intersecting the first direction (X), but is not limited thereto, and the first direction (X) may be the vertical direction of the vibration layer 511a, and the second direction (Y) may be the horizontal direction of the vibration layer 511a.

[0160] Each of the first portions 511a1 may be made of an inorganic material. The inorganic material may include a piezoelectric material having a piezoelectric effect, a composite piezoelectric material, or an electroactive material, but the embodiments of the present specification are not limited thereto.

[0161] Each of the first portions 511a1 may be made of a ceramic-based material capable of realizing a relatively high vibration, or may be made of a piezoelectric ceramic having a perovskite-based crystal structure. The perovskite crystal structure may have a piezoelectric and / or inverse piezoelectric effect and may be an oriented structure (e.g., a plate-shaped or film-shaped structure). The perovskite crystal structure may be an ABO 3 The A site may be composed of a divalent metal element and the B site may be composed of a tetravalent metal element. 3 In the chemical formula, the A site and the B site may be cations, and O may be an anion. For example, each of the first portions 511a1 may be PbTiO 3 , PbZrO 3 , PbZrTiO 3 , BaTiO 3 , and SrTiO 3 However, examples herein are not limited thereto.

[0162] The perovskite crystal structure can be transformed by external stress or magnetic field to displace the central ions, e.g., PbTiO 3 In this case, the position of titanium (Ti) ions fluctuates, causing a change in polarization or poling, which can generate a piezoelectric effect. For example, the perovskite crystal structure can change from a symmetric cubic shape to an unsymmetric tetragonal, orthorhobic, or rhombohedral shape due to external stress or magnetic field, generating a piezoelectric effect. Since the polarization is high at the morphotropic phase boundary of the tetragonal or rhombohedral, which has an asymmetric structure, and the polarization can be easily rearranged, the material can have high piezoelectric properties.

[0163] The vibration layer 511a or first portion 511a1 according to other embodiments of the present specification may include one or more of lead (Pb), zirconium (Zr), titanium (Ti), zinc (Zn), nickel (Ni), and niobium (Nb), although embodiments of the present specification are not limited thereto.

[0164] According to other embodiments of the present specification, the vibration layer 511a or the first portion 511a1 may include a PZT (lead zirconate titanate)-based material including lead (Pb), zirconium (Zr), and titanium (Ti), or a PZNN (lead zirconate nickel niobate)-based material including lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb), but the embodiments of the present specification are not limited thereto. In addition, the vibration layer 511a or the first portion 511a1 may include CaTiO 3 , BaTiO 3 , and SrTiO 3 However, examples herein are not limited thereto.

[0165] Each of the plurality of first portions 511a1 according to the embodiment of the present specification may be disposed between the plurality of second portions 511a2 and may have a first width (W1) parallel to the second direction (Y) (or the first direction (X)) and a length parallel to the first direction (X) (or the second direction (Y)). Each of the plurality of second portions 511a2 may have a second width (W2) parallel to the second direction (Y) (or the first direction (X)) and a length parallel to the first direction (X) (or the second direction (Y)). The first width (W1) may be the same as or different from the second width (W2). For example, the first width (W1) may be larger than the second width (W2). For example, the first portion 511a1 and the second portion 511a2 may include a line shape or a stripe shape having the same or different sizes. Therefore, the vibration layer 511a may have a resonant frequency of 20 kHz or less by having a 2-2 composite structure having piezoelectric characteristics of a 2-2 vibration mode, but the embodiments of the present specification are not limited thereto. For example, the resonant frequency of the vibration layer 511a may be changed by at least one or more of the shape, length, and thickness of the first portion 511a1.

[0166] In the vibration layer 511a, the plurality of first portions 511a1 and the plurality of second portions 511a2 may be arranged (or arrayed) next to each other on the same plane (or the same layer). Each of the plurality of second portions 511a2 may be connected or bonded to the adjacent first portions 511a1 by being configured to fill the gap between two adjacent first portions 511a1. This allows the vibration layer 511a to be expanded to a desired size or length by the side connection (or connection) of the first portions 511a1 and the second portions 511a2.

[0167] In the vibration layer 511a, the width (W2) of each of the plurality of second portions 511a2 may be gradually reduced from the middle portion of the vibration layer 511a or the vibration element 200 toward both edge portions (or both tips).

[0168] According to an embodiment of the present specification, the second portion 511a2 having the largest width (W2) among the plurality of second portions 511a2 may be located at a portion where the largest stress is concentrated when the vibration layer 511a or the vibration element 200 vibrates in the vertical direction (Z) (or thickness direction). The second portion 511a2 having the smallest width (W2) among the plurality of second portions 511a2 may be located at a portion where the smallest stress is generated relatively when the vibration layer 511a or the vibration element 200 vibrates in the vertical direction (Z). For example, the second portion 511a2 having the largest width (W2) among the plurality of second portions 511a2 may be disposed in a middle portion of the vibration layer 511a, and the second portion 511a2 having the smallest width (W2) among the plurality of second portions 511a2 may be disposed at both edge portions of the vibration layer 511a. As a result, when the vibration layer 511a or the vibration element 200 vibrates in the vertical direction (Z), the interference of sound waves generated at the portion where the greatest stress is concentrated or the overlap of resonance frequencies can be minimized, and thus the dip phenomenon of sound pressure generated in the low frequency band can be improved and the flatness of acoustic characteristics in the low frequency band can be improved. For example, the flatness of acoustic characteristics can be the magnitude of deviation between the maximum sound pressure and the minimum sound pressure.

[0169] In the vibration layer 511a, each of the first portions 511a1 may have a different size (or area). For example, the size (or area) of each of the first portions 511a1 may gradually decrease or increase from the middle portion of the vibration layer 511a or the vibration element 200 toward both edge portions (or both tips). In this case, the vibration layer 511a may have improved sound pressure characteristics and a wider sound reproduction band due to various natural vibration frequencies caused by the vibration of each of the first portions 511a1 having different sizes.

[0170] Each of the second portions 511a2 may be disposed between the first portions 511a1. As a result, the vibration layer 511a or the vibration element 200 may increase the vibration energy due to the link in the unit cell of the first portion 511a1 by the second portion 511a2, so that the vibration characteristics may be increased and the piezoelectric characteristics and flexibility may be ensured. For example, the second portion 511a2 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 specification are not limited thereto.

[0171] Each of the second parts 511a2 according to the embodiment of the present specification may be made of an organic material part. For example, the organic material part may be disposed between the inorganic material parts to absorb impacts applied to the inorganic material part (or the first part), to release stress concentrated on the inorganic material part, to improve durability of the vibration layer 511a or the vibration element 200, and to provide flexibility to the vibration layer 511a or the vibration element 200. The vibration element 200 may have flexibility. For example, the vibration element 200 may be configured to bend into a non-planar shape including a curved surface. Thus, the vibration element 200 may have flexibility and be disposed in a shape corresponding to the shape of the curved surface of the coupler 400 or the vibration member 20.

[0172] The second portion 511a2 according to the embodiment of the present specification may have a lower modulus (or Young's modulus) and viscoelasticity than the first portion 511a1, thereby improving the reliability of the first portion 511a1, which is vulnerable to impact due to the brittle characteristics of the first portion 511a1. For example, the second portion 511a2 may be made of a material having a loss factor of 0.01 to 1 and a modulus of 0.1 to 10 GPa (Giga Pascal).

[0173] The organic material portion of the second portion 511a2 may include an organic material, an organic polymer, an organic piezoelectric material, or an organic non-piezoelectric material having a flexible characteristic compared to the inorganic material portion of the first portion 511a1. For example, the second portion 511a2 may be expressed as a flexible adhesive portion, an expandable portion, a bending portion, a damping portion, or a soft portion, but the embodiments of the present specification are not limited thereto.

[0174] The vibration layer 511a according to the embodiment of the present specification may have a single thin film shape by arranging (or connecting) a plurality of first portions 511a1 and a plurality of second portions 511a2 on the same plane. For example, the vibration layer 511a may have a structure in which a plurality of first portions 511a1 are connected to one side. For example, the plurality of first portions 511a1 may have a structure in which they are connected by the entire vibration layer 511a. For example, the vibration layer 511a may vibrate in the vertical direction by the first portion 511a1 having vibration characteristics, and may bend into a curved shape by the second portion 511a2 having flexibility. In the vibration layer 511a according to the embodiment of the present specification, the size of the first portion 511a1 and the size of the second portion 511a2 may be set according to the piezoelectric characteristics and flexibility required for the vibration layer 511a or the vibration element 200. As an embodiment of the present specification, in the case of vibration layer 511a that requires piezoelectric characteristics rather than flexibility, the size of first portion 511a1 may be configured to be larger than the size of second portion 511a2. As another embodiment of the present specification, in the case of vibration layer 511a that requires flexibility rather than piezoelectric characteristics, the size of second portion 511a2 may be configured to be larger than the size of first portion 511a1. Therefore, since the size of vibration layer 511a can be adjusted according to the required characteristics, there is an advantage that vibration layer 511a can be easily designed.

[0175] The first electrode layer 511b may be disposed on the first surface (or upper surface) of the vibration layer 511a. The first electrode layer 511b may be commonly disposed or coupled to the first surfaces of each of the plurality of first portions 511a1 and each of the plurality of second portions 511a2, and may be electrically coupled to the first surfaces of each of the plurality of first portions 511a1. For example, the first electrode layer 511b may have a single electrode (or one electrode) shape disposed over the entire first surface of the vibration layer 511a. For example, the first electrode layer 511b may have substantially the same shape as the vibration layer 511a, but the embodiments of the present specification are not limited thereto.

[0176] The second electrode layer 511c may be disposed on a second surface (or back surface) different from (or opposite to) the first surface of the vibration layer 511a. The second electrode layer 511c may be commonly disposed or coupled to the second surface of each of the plurality of first portions 511a1 and the second surface of each of the plurality of second portions 511a2, and may be electrically coupled to the second surface of each of the plurality of first portions 511a1. For example, the second electrode layer 511c may have a single electrode (or one electrode) shape disposed over the entire second surface of the vibration layer 511a. For example, the second electrode layer 511c may have the same shape as the vibration layer 511a, but the examples of the present specification are not limited thereto. For example, one or both of the first electrode layer 511b and the second electrode layer 511c may be formed of a pattern-shaped electrode disposed to correspond only to each of the plurality of first portions 511a1.

[0177] One or more of the first electrode layer 511b and the second electrode layer 511c according to the embodiment of the present specification may be made of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, the transparent or semi-transparent conductive material may include, but is not limited to, ITO (indium tin oxide) or IZO (indium zinc oxide). The opaque conductive material may include, but is not limited to, aluminum (Al), copper (Cu), gold (Au), silver (Ag), molybdenum (Mo), magnesium (Mg), or the like, or may be made of an alloy thereof.

[0178] The vibration layer 511a may be poled by a constant voltage applied to the first electrode layer 511b and the second electrode layer 511c in a constant temperature atmosphere or a temperature atmosphere that changes from high temperature to room temperature, but the embodiments of the present specification are not limited thereto. For example, the vibration layer 511a may vibrate by alternately repeating contraction and / or expansion due to an inverse piezoelectric effect caused by an acoustic signal (or a voice signal or a drive signal) applied from the outside to the first electrode layer 511b and the second electrode layer 511c. For example, the vibration layer 511a may vibrate by vibration in the vertical direction (or thickness direction) and vibration in the planar direction due to an acoustic signal applied to the first electrode layer 511b and the second electrode layer 511c. The vibration layer 511a may increase the displacement of the vibration member by contracting and / or expanding in the planar direction, thereby further improving the vibration of the vibration member.

[0179] The vibration element 200 according to the embodiment of the present specification may further include a first cover member 512 and a second cover member 513.

[0180] The first cover member 512 may be disposed on a first surface of the vibration portion 511. For example, the first cover member 512 may be configured to cover the first electrode layer 511b. Thus, the first cover member 512 can protect the first electrode layer 511b.

[0181] The second cover member 513 may be disposed on a second surface of the vibration portion 511. For example, the second cover member 513 may be configured to cover the second electrode layer 511c. Thus, the second cover member 513 can protect the second electrode layer 511c.

[0182] Each of the first cover member 512 and the second cover member 513 according to the embodiment of the present specification may include one or more materials of plastic, fiber, cloth, paper, leather, rubber, carbon, and wood, but the embodiment of the present specification is not limited thereto. For example, each of the first cover member 512 and the second cover member 513 may include the same or different materials. For example, each of the first cover member 512 and the second cover member 513 may be a polyimide film or a polyethylene terephthalate film, but the embodiment of the present specification is not limited thereto.

[0183] The first cover member 512 according to the embodiment of the present specification may be connected or bonded to the first electrode layer 511b via the first adhesive layer 514. For example, the first cover member 512 may be connected or bonded to the first electrode layer 511b by a film lamination process using the first adhesive layer 514 as an intermediate.

[0184] The second cover member 513 according to the embodiment of the present specification may be connected or bonded to the second electrode layer 511c via the second adhesive layer 515. For example, the second cover member 513 may be connected or bonded to the second electrode layer 511c by a film lamination process via the second adhesive layer 515. For example, the vibration element 200 may be realized by one film using the first cover member 512 and the second cover member 513.

[0185] The first adhesive layer 514 may be disposed between the first electrode layer 511b and the first cover member 512. The second adhesive layer 515 may be disposed between the second electrode layer 511c and the second cover member 513.

For example, the vibration layer 511a and the first electrode layer 511b and the second electrode layer 511c may be embedded or built-in between the first adhesive layer 514 and the second adhesive layer 515.

[0186] Each of the first adhesive layer 514 and the second adhesive layer 515 according to the embodiment of the present specification may include an electrically insulating material that has adhesiveness and is compressible and resilient. For example, each of the first adhesive layer 514 and the second adhesive layer 515 may include an epoxy resin, an acrylic resin, a silicone resin, or a urethane resin, but the embodiment of the present specification is not limited thereto.

[0187] The vibration element 200 according to an embodiment of the present specification may further include a first power supply line (PL1) arranged on the first cover member 512, a second power supply line (PL2) arranged on the second cover member 513, and a pad part 516 electrically connected to the first power supply line (PL1) and the second power supply line (PL2).

The first power supply line (PL1) may be extended long along the second direction (Y) (or the first direction (X)) and electrically connected to a central portion of the first electrode layer 511b, but the embodiments of the present specification are not limited thereto.

As another embodiment of the present specification, the first power supply line (PL1) may be electrically connected to the first electrode layer 511b via a conductive material (or particles) contained in the first adhesive layer 514.

[0189] The second power supply line (PL2) may be disposed between the second electrode layer 511c and the second cover member 513 and electrically connected to the second electrode layer 511c.

[0190] According to the embodiment of the present specification, the first power supply line (PL1) may be arranged so as not to overlap with the second power supply line (PL2). When the first power supply line (PL1) is arranged so as not to overlap with the second power supply line (PL2), the problem of a short circuit between the first power supply line (PL1) and the second power supply line (PL2) may be improved.

[0191] The pad portion 516 may be configured on an edge portion of one side of either the first cover member 512 or the second cover member 513 so as to be electrically connected to one side (or one end) of each of the first power supply line (PL1) and the second power supply line (PL2).

[0193] The first pad electrode may be disposed on an edge portion on one side of either the first cover member 512 or the second cover member 513, and may be connected to one end of the first power supply line (PL1). For example, the first pad electrode may pass through either the first cover member 512 or the second cover member 513 and be electrically connected to one end of the first power supply line (PL1).

[0194] The second pad electrode may be arranged side by side with the first pad electrode and connected to one end of the second power supply line (PL2). For example, the second pad electrode may be electrically connected to one end of the second power supply line (PL2) by penetrating either the first cover member 512 or the second cover member 513. The first power supply line (PL1) and the second power supply line (PL2) according to the embodiment of the present specification may be drawn out through at least one or more homes 406 of the coupler 400 described with reference to FIGS. 4 to 7.

[0195] According to embodiments of the present disclosure, each of the first power supply line (PL1), the second power supply line (PL2), and the pad portion 516 may be configured to be transparent, semi-transparent, or opaque.

[0196] The pad portion 516 according to the embodiment of the present disclosure may be electrically connected to a signal cable 517 .

The signal cable 517 according to the embodiment of the present specification may include a first terminal electrically connected to a first pad electrode of the pad portion 516, and a second terminal electrically connected to a second pad electrode of the pad portion 516. For example, the signal cable 517 may be composed of a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multilayer printed circuit, or a flexible multilayer printed circuit board, but the embodiment of the present specification is not limited thereto.

[0200] The signal cable 517 according to the embodiment of the present specification may be led out through at least one or more homes 406 of the coupler 400 described with reference to FIGS.

[0201] The vibration element 200 according to the embodiment of the present specification may be realized in a thin film shape by alternately and repeatedly connecting the first portion 511a1 having a piezoelectric property and the second portion 511a2 having flexibility. As a result, the vibration element 200 may be bent into a shape corresponding to the curved portion of the vibration member 20 and / or the shape of the vibration member 20 and / or the coupler 400. For example, when the vibration element 200 is connected or coupled to the vibration member 20 including various curved portions via a connecting member, it may be bent into a curved shape along the shape of the curved portion of the coupler 400 and / or the vibration member 20, and reliability such as damage or breakage is not reduced even when it is bent into a curved shape. And, the vibration width (or displacement width) of the vibration element 200 according to the embodiment of the present specification may be increased by the second portion 511a2 having flexibility.

[0202] FIG. 14 is a diagram showing the vibrating portion shown in FIG. 13 according to another embodiment of the present specification.

[0203] Referring to FIG. 14, a vibration layer 511a according to another embodiment of the present specification may include a plurality of first portions 511a1 spaced apart from each other along a first direction (X) and a second direction (Y), and a second portion 511a2 arranged between the plurality of first portions 511a1.

[0204] The first portions 511a1 may be arranged to be spaced apart from each other along the first direction (X) and the second direction (Y). For example, the first portions 511a1 may be arranged in a lattice shape, each having a hexahedral shape of the same size. Since the first portions 511a1 are substantially the same as or similar to the first portions 511a1 described with reference to FIGS. 11 to 13, the same reference numerals are used therefor, and a duplicate description thereof may be omitted or briefly described.

[0205] The second portion 511a2 may be disposed between the first portions 511a1 along each of the first direction (X) and the second direction (Y). The second portion 511a2 may be connected or bonded to the adjacent first portions 511a1 by filling a gap between two adjacent first portions 511a1 or by being configured to surround each of the first portions 511a1. According to an embodiment of the present specification, the width (W4) of the second portion 511a2 disposed between two adjacent first portions 511a1 along the first direction (X) may be the same as or different from the width (W3) of the first portion 511a1, and the width (W4) of the second portion 511a2 disposed between two adjacent first portions 511a1 along the second direction (Y) may be the same as or different from the width (W3) of the first portion 511a1.

[0206] The vibration layer 511a according to another embodiment of the present specification may have a resonant frequency of 30 MHz or less by including a 1-3 composite structure having a piezoelectric characteristic of a 1-3 vibration mode, but the embodiment of the present specification is not limited thereto.

For example, each of the first portions 511a1 may have a dot shape including an elliptical shape, a polygonal shape, or a doughnut shape. Each of the first portions 511a1 is substantially the same as or similar to the first portion 511a1 described with reference to FIGS. 11 to 13, and therefore the same reference numerals are given thereto, and a duplicate description thereof may be omitted or briefly described.

The first portions 511a1 and the second portions 511a2 may be disposed (or arranged) side by side on the same plane (or the same layer). For example, the second portion 511a2 is substantially the same as or similar to the second portion 511a2 described with reference to FIGS. 11 to 13, and therefore the same reference numerals are given thereto, and a duplicated description thereof may be omitted or briefly described.

Each of the first portions 511a1 is substantially the same as or similar to the first portion 511a1 described with reference to Figures 11 to 13, and therefore the same reference numerals are given thereto, and redundant description thereof may be omitted or briefly described.

[0214] According to an embodiment of the present specification, four adjacent first portions 511a1 among the plurality of first portions 511a1 may be adjacently disposed to form a square shape (or a regular square shape). Each vertex of the four adjacent first portions 511a1 forming the square shape may be adjacently disposed to the center (or the exact center) of the square shape.

[0215] The second portion 511a2 may be disposed between the first portions 511a1 along each of the first direction (X) and the second direction (Y). The second portion 511a2 may be configured adjacent to each of the first portions 511a1 or configured to surround each of the first portions 511a1, and may be connected or bonded to each side of the first portions 511a1. The first portions 511a1 and the second portions 511a2 may be disposed (or arranged) next to each other on the same plane (or the same layer). For example, the second portion 511a2 is substantially the same as or similar to the second portion 511a2 described with reference to FIGS. 11 to 13, and therefore the same reference numerals are given thereto, and a duplicated description thereof may be omitted or briefly described.

[0216] According to another embodiment of the present specification, adjacent 2N (N is a natural number equal to or greater than 2) first portions 511a1 among the plurality of first portions 511a1 having a triangular shape may be adjacently arranged to form a 2N-sided polygon.

Each of the plurality of first portions 511a1 and second portions 511a2 may be disposed (or arranged) next to one another on the same plane (or the same layer).

[0217] Fig. 17 is a diagram showing a vibration element according to another embodiment of the present specification. Fig. 18 is a cross-sectional view taken along line BB' shown in Fig. 17 according to another embodiment of the present specification. Figs. 17 and 18 are diagrams showing another embodiment of the vibration element described with reference to Figs. 1 to 10B.

[0218] 17 and 18, the vibration element 200 or vibration portion according to other embodiments of the present specification may include at least two or more vibration portions between the first cover member 512 and the second cover member 513. The vibration element 200 according to other embodiments of the present specification may include first and second vibration portions 511-1, 511-2.

[0219] The first and second vibrating parts 511-1, 511-2 may be arranged electrically separated from each other along the first direction (X). The first and second vibrating parts 511-1, 511-2 may vibrate by alternately or repeatedly contracting and / or expanding due to the piezoelectric effect. For example, the first and second vibrating parts 511-1, 511-2 may be arranged at regular intervals or tiled along the first direction (X). As a result, the vibrating element 200 in which the first and second vibrating parts 511-1, 511-2 are tiled may be a vibrating array, a vibrating array section, a vibrating module array section, a vibrating array structure, a tiling vibrating array, a tiling vibrating array module, or a tiling vibrating film.

[0220] Each of the first and second vibration parts 511-1, 511-2 according to the embodiment of the present specification may have a rectangular shape. For example, each of the first and second vibration parts 511-1, 511-2 may have a rectangular shape with a width of 5 cm or more. For example, each of the first and second vibration parts 511-1, 511-2 may have a square shape with a size of 5 cm x 5 cm or more, but the embodiment of the present specification is not limited thereto.

[0221] The first and second vibrating parts 511-1, 511-2 are arranged on the same plane or tiled, so that the vibration element 200 can be made larger in area by tiling the first and second vibrating parts 511-1, 511-2, which have relatively small sizes.

[0222] Each of the first and second vibration units 511-1, 511-2 may be realized as one vibration device (or a single vibration device) that is not driven independently but driven in the shape of one complete unit by being arranged at a regular interval or tiled. According to an embodiment of the present specification, the first separation distance (D1) between the first and second vibration units 511-1, 511-2 based on the first direction (X) may be 0.1 mm or more and less than 3 cm, but the embodiment of the present specification is not limited thereto.

[0223] According to an embodiment of the present specification, the first and second vibrating units 511-1, 511-2 may be arranged or tiled to have a separation distance (or interval) (D1) of 0.1 mm or more and less than 3 cm, so that they can be driven as one vibrating device, and the reproduction band and sound pressure characteristics of the sound generated in conjunction with the single-body vibration of the first and second vibrating units 511-1, 511-2 may be increased. For example, in order to increase the reproduction band of the sound generated in conjunction with the single-body vibration of the first and second vibrating units 511-1, 511-2 and to increase the sound pressure characteristics of low-frequency sound, for example, at 500 Hz or less, the first and second vibrating units 511-1, 511-2 may be arranged at an interval (D1) of 0.1 mm or more and less than 5 mm.

[0224] According to embodiments of the present specification, when the first and second vibrating parts 511-1, 511-2 are arranged with a gap (D1) of less than 0.1 mm or no gap (D1), the reliability of the first and second vibrating parts 511-1, 511-2 or the vibration element 200 may be reduced due to cracks or damage caused by physical contact between each other when the first and second vibrating parts 511-1, 511-2 vibrate, respectively.

[0225] According to an embodiment of the present specification, when the first and second vibration parts 511-1, 511-2 are arranged at an interval (D1) of 3 cm or more, the first and second vibration parts 511-1, 511-2 may not be driven as one vibration device due to the independent vibration of each of them. This may result in a decrease in the reproduction band and sound pressure characteristics of the sound generated by the vibration of the first and second vibration parts 511-1, 511-2. For example, when the first and second vibration parts 511-1, 511-2 are arranged at an interval (D1) of 3 cm or more, the acoustic characteristics and sound pressure characteristics in the low frequency band, for example, below 500 Hz, may each be decreased.

[0226] According to an embodiment of the present specification, when the first and second vibration parts 511-1, 511-2 are arranged at a distance (D1) of 5 mm, the first and second vibration parts 511-1, 511-2 are not driven as a single vibration device, and therefore the acoustic characteristics and sound pressure characteristics may be degraded in the low frequency range, for example, below 200 Hz.

[0227] According to another embodiment of the present specification, when the first and second vibration parts 511-1, 511-2 are arranged at an interval (D1) of 1 mm, the first and second vibration parts 511-1, 511-2 are vibrated as one vibration device, so that the reproduction band of the sound is increased, and the characteristics of the sound in the low frequency band, for example, the sound pressure at 500 Hz or less, can be increased. For example, when the first and second vibration parts 511-1, 511-2 are arranged at an interval (D1) of 1 mm, the vibration element 200 can be realized as a large-area vibration body by optimizing the separation distance between the first and second vibration parts 511-1, 511-2. As a result, the vibration element 200 can be driven as a large-area vibration body by the single body vibration of the first and second vibration parts 511-1, 511-2, and thus the reproduction band of the sound generated in conjunction with the vibration of the large area of ​​the vibration element 200 and the acoustic characteristics and sound pressure characteristics of the low frequency band can be increased or improved.

[0228] Therefore, in order to realize the single body vibration (or one vibration device) of the first and second vibration parts 511-1, 511-2, the separation distance (D1) between the first and second vibration parts 511-1, 511-2 may be set to 0.1 mm or more and less than 3 cm. Alternatively, in order to realize the single body vibration (or one vibration device) of the first and second vibration parts 511-1, 511-2 and increase the sound pressure characteristics of the sound in the low frequency range, the separation distance (D1) between the first and second vibration parts 511-1, 511-2 may be set to 0.1 mm or more and less than 5 mm.

[0229] Each of the first and second vibrating parts 511-1, 511-2 according to the embodiment of the present specification may include a vibrating layer 511a, a first electrode layer 511b, and a second electrode layer 511c.

[0230] The vibration layer 511a of each of the first and second vibration units 511-1 and 511-2 may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the vibration layer 511a of each of the first and second vibration units 511-1 and 511-2 may be substantially the same or similar to any of the vibration layers 511a described with reference to Figs. 11 to 16, and therefore the same reference numerals may be given to the vibration layers 511a, and the description thereof may be omitted or simplified.

[0231] According to the embodiments of the present specification, each of the first and second vibrating parts 511-1, 511-2 may include any one of the vibrating parts 511 described with reference to Figures 11 to 16, or may include different vibrating parts 511 from each other.

[0232] The first electrode layer 511b may be disposed on a first surface of the vibration layer 511a and electrically connected to the first surface of the vibration layer 511a. The first electrode layer 511b is substantially the same as or similar to the first electrode layer 511b described with reference to Figures 11 to 16, and therefore the same reference numerals are used therefor, and redundant description thereof may be omitted or briefly described.

[0233] The second electrode layer 511c may be disposed on a second surface of the vibration layer 511a and electrically connected to the second surface of the vibration layer 511a. The second electrode layer 511c is substantially the same as or similar to the second electrode layer 511c described with reference to Figures 11 to 16, and therefore the same reference numerals are used therefor, and redundant description thereof may be omitted or briefly described.

[0234] The vibration element 200 according to another embodiment of the present disclosure may further include a first cover member 512 and a second cover member 513.

[0235] The first cover member 512 may be disposed on the first surface of the vibration element 200. For example, the first cover member 512 may be commonly connected to the first surfaces of the first and second vibration parts 511-1 and 511-2 or commonly support the first surfaces of the first and second vibration parts 511-1 and 511-2 by covering the first electrode layers 511b disposed on the first surfaces of the first and second vibration parts 511-1 and 511-2. This allows the first cover member 512 to protect the first surfaces or the first electrode layers 511b of the first and second vibration parts 511-1 and 511-2.

[0236] The second cover member 513 may be disposed on the second surface of the vibration element 200. For example, the second cover member 513 may be commonly connected to the second surfaces of the first and second vibration parts 511-1 and 511-2 or commonly support the second surfaces of the first and second vibration parts 511-1 and 511-2 by covering the second electrode layers 511c disposed on the second surfaces of the first and second vibration parts 511-1 and 511-2. This allows the second cover member 513 to protect the second surfaces or the second electrode layers 511c of the first and second vibration parts 511-1 and 511-2.

[0237] Each of the first cover member 512 and the second cover member 513 according to the embodiment of the present specification may include one or more materials of plastic, fiber, leather, rubber, wood, cloth, carbon, and paper, but the embodiment of the present specification is not limited thereto. For example, each of the first cover member 512 and the second cover member 513 may include the same or different materials. For example, each of the first cover member 512 and the second cover member 513 may be a polyimide film or a polyethylene terephthalate film, but the embodiment of the present specification is not limited thereto.

[0238] The first cover member 512 according to the embodiment of the present specification may be disposed on the first surfaces of the first and second vibrating parts 511-1, 511-2 via the first adhesive layer 514. For example, the first cover member 512 may be disposed directly on the first surfaces of the first and second vibrating parts 511-1, 511-2 by a film lamination process using the first adhesive layer 514 as an intermediary. Thus, each of the first and second vibrating parts 511-1, 511-2 may be integrated (or disposed) with or tiled to the first cover member 512 so as to have a constant interval (D1).

[0239] The second cover member 513 according to the embodiment of the present specification may be disposed on the second surfaces of the first and second vibrating parts 511-1, 511-2 via the second adhesive layer 515. For example, the second cover member 513 may be disposed directly on the second surfaces of the first and second vibrating parts 511-1, 511-2 by a film lamination process using the second adhesive layer 515 as an intermediary. Thus, each of the first and second vibrating parts 511-1, 511-2 may be integrated (or disposed) or tiled with the second cover member 513 so as to have a certain interval (D1). For example, the vibration element 200 may be realized by one film using the first cover member 512 and the second cover member 513. For example, the first and second vibrating parts 511-1, 511-2 can be integrated with the first cover member 512 and the second cover member 513 by being arranged side by side on the same plane (or the same layer) between the first cover member 512 and the second cover member 513.

[0240] The first adhesive layer 514 may be disposed between the first and second vibrating parts 511-1, 511-2 and disposed on the first surfaces of the first and second vibrating parts 511-1, 511-2. For example, the first adhesive layer 514 may be formed on the back surface (or inner surface) of the first cover member 512 facing the first surfaces of the first and second vibrating parts 511-1, 511-2, filled between the first and second vibrating parts 511-1, 511-2, and disposed between the first cover member 512 and the first surfaces of the first and second vibrating parts 511-1, 511-2.

[0241] The second adhesive layer 515 may be disposed between the first and second vibrating parts 511-1, 511-2 and disposed on the second surfaces of the first and second vibrating parts 511-1, 511-2. For example, the second adhesive layer 515 may be formed on the front surface (or inner surface) of the second cover member 513 facing the second surfaces of the first and second vibrating parts 511-1, 511-2, filled between the first and second vibrating parts 511-1, 511-2, and disposed between the second cover member 513 and the second surfaces of the first and second vibrating parts 511-1, 511-2.

[0242] The first and second adhesive layers 514, 515 may be interconnected or bonded between the first and second vibrating parts 511-1, 511-2. Thus, each of the first and second vibrating parts 511-1, 511-2 may be surrounded by the first and second adhesive layers 514, 515. For example, the first and second adhesive layers 514, 515 may be configured between the first cover member 512 and the second cover member 513 so as to completely surround each of the first and second vibrating parts 511-1, 511-2. For example, each of the first and second vibrating parts 511-1, 511-2 may be embedded or built-in between the first adhesive layer 514 and the second adhesive layer 515.

[0243] Each of the first and second adhesive layers 514, 515 according to the embodiment of the present specification may include an electrically insulating material that is adhesive and capable of being compressed and restored. For example, each of the first and second adhesive layers 514, 515 may include an epoxy resin, an acrylic resin, a silicone resin, or a urethane resin, but the embodiment of the present specification is not limited thereto. For example, each of the first and second adhesive layers 514, 515 may be configured to be transparent, translucent, or opaque.

[0244] The vibration element 200 according to another embodiment of the present specification may further include a first power supply line (PL1) arranged on the first cover member 512, a second power supply line (PL2) arranged on the second cover member 513, and a pad portion 518 electrically connected to the first power supply line (PL1) and the second power supply line (PL2).

[0245] The first power supply line (PL1) may be disposed on a rear surface of the first cover member 512 facing the first surfaces of the first and second vibrating parts 511-1, 511-2. The first power supply line (PL1) may be coupled or electrically coupled to the first electrode layers 511b of the first and second vibrating parts 511-1, 511-2. For example, the first power supply line (PL1) may be electrically coupled to the first electrode layers 511b of the first and second vibrating parts 511-1, 511-2 via an anisotropic conductive film or a conductive material (or particles) contained in the first adhesive layer 514.

[0246] The first power supply line (PL1) according to the embodiment of the present specification may include first and second upper power lines (PL11, PL12) arranged along the second direction (Y). For example, the first upper power line (PL11) may be connected to or directly electrically connected to the first electrode layer 511b of the first vibrating part 511-1. The second upper power line (PL12) may be connected to or directly electrically connected to the first electrode layer 511b of the second vibrating part 511-2.

[0247] The second power supply line (PL2) may be disposed on a front surface of the second cover member 513 facing the second surfaces of the first and second vibrating parts 511-1, 511-2. The second power supply line (PL2) may be coupled to or directly electrically coupled to the second electrode layers 511c of the first and second vibrating parts 511-1, 511-2. For example, the second power supply line (PL2) may be electrically coupled to the second electrode layers 511c of the first and second vibrating parts 511-1, 511-2 via an anisotropic conductive film or a conductive material (or particles) contained in the second adhesive layer 515.

[0248] The second power supply line (PL2) according to the embodiment of the present specification may include first and second lower power lines (PL21, PL22) arranged along the second direction (Y). The first lower power line (PL21) may be connected to the second electrode layer 511c of the first vibrating part 511-1 or may be directly connected electrically. For example, the first lower power line (PL21) may be arranged so as not to overlap with the first upper power line (PL11). When the first lower power line (PL21) is arranged so as not to overlap with the first upper power line (PL11), the problem of a short circuit between the first power supply line (PL1) and the second power supply line (PL2) may be improved. The second lower power line (PL22) may be connected to the second electrode layer 511c of the second vibrating part 511-2 or may be directly connected electrically. For example, the second lower power line (PL22) may be arranged so as not to overlap with the second upper power line (PL12). When the second lower power line (PL22) is arranged so as not to overlap with the second upper power line (PL12), the problem of a short circuit between the first power supply line (PL1) and the second power supply line (PL2) can be improved.

[0249] The pad portion 518 may be configured on an edge portion of one side of either the first cover member 512 or the second cover member 513 so as to be electrically connected to one side (or one end) of each of the first power supply line (PL1) and the second power supply line (PL2).

[0250] The pad part 518 according to an embodiment of the present specification may include a first pad electrode electrically connected to one end of the first power supply line (PL1) and a second pad electrode electrically connected to one end of the second power supply line (PL2).

[0251] The first pad electrode may be commonly connected to one end of each of the first and second upper power lines (PL11, PL12) of the first power supply line (PL1). For example, one end of each of the first and second upper power lines (PL11, PL12) may branch off from the first pad electrode. The second pad electrode may be commonly connected to one end of each of the first and second lower power lines (PL21, PL22) of the second power supply line (PL2). For example, one end of each of the first and second lower power lines (PL21, PL22) may branch off from the second pad electrode.

[0252] The vibration element 200 according to other embodiments of the present disclosure may further include a signal cable 519 .

[0253] The signal cable 519 is electrically connected to the pad portion 518 disposed on the vibration element 200, and can supply a vibration drive signal (or an acoustic signal or a voice signal) provided from the sound processing circuit to the vibration element 200. The signal cable 519 according to the embodiment of the present specification may include a first terminal electrically connected to a first pad electrode of the pad portion 518, and a second terminal electrically connected to a second pad electrode of the pad portion 518. For example, the signal cable 519 may be composed of a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multilayer printed circuit, or a flexible multilayer printed circuit board, but the embodiment of the present specification is not limited thereto.

[0254] The signal cable 519 according to the embodiment of the present specification may be led out through at least one or more homes 406 of the coupler 400 described with reference to FIGS.

[0255] The sound processing circuit can generate an AC vibration drive signal including a first vibration drive signal and a second vibration drive signal based on the sound data. The first vibration drive signal can be either a positive polarity (+) vibration drive signal or a negative polarity (-) vibration drive signal, and the second vibration drive signal can be either a positive polarity (+) vibration drive signal or a negative polarity (-) vibration drive signal. For example, the first vibration drive signal can be supplied to the first electrode layer 511b of each of the first and second vibration units 511-1 and 511-2 via a first terminal of the signal cable 519, a first pad electrode of the pad unit 518, and a first power supply line (PL1). The second vibration drive signal can be supplied to the second electrode layer 511c of each of the first and second vibration units 511-1 and 511-2 via a second terminal of the signal cable 519, a second pad electrode of the pad unit 518, and a second power supply line (PL2). The first power supply line (PL1) and the second power supply line (PL2) according to the embodiment of the present specification may be drawn out through at least one or more homes 406 of the coupler 400 described with reference to FIGS.

[0256] The vibration element 200 according to another embodiment of the present specification may be realized in the form of a thin film. As a result, the vibration element 200 can be bent into a shape corresponding to the shape of a vibration member or a vibration target object, and can easily vibrate a vibration member including various curved surfaces, thereby improving the acoustic characteristics and / or sound pressure characteristics in the low frequency range generated by the vibration of the vibration member. The vibration element 200 according to another embodiment of the present specification may be driven as a large-area vibration body by the single-body vibration of the first and second vibration generating units 511-1 and 511-2 by including the first and second vibration units 511-1 and 511-2 arranged (or tiled) at a constant interval (D1) so as to be realized as one single vibration body without being driven independently. Therefore, the vibration element 200 is realized as one single vibration body, and therefore can be driven as a large-area vibration body that can be applied to a vibration member having a large area or a display panel.

[0257] FIG. 19 is a diagram showing a vibration element according to another embodiment of the present specification. FIG. 19 shows a vibration element shown in FIG. 17 and FIG. 18 according to another embodiment of the present specification, in which four vibration parts are configured. Therefore, in the following, the remaining configurations other than the four vibration parts and the configurations related thereto are given the same reference numerals in the drawings, and duplicated descriptions thereof are omitted or simplified. The cross section of line B-B' shown in FIG. 19 is also shown in FIG. 18.

[0258] 18 and 19, a vibration element 200 according to another embodiment of the present specification may include a plurality of vibration parts 511-1, 511-2, 511-3, and 511-4.

[0259] Each of the multiple vibration parts 511-1, 511-2, 511-3, and 511-4 may be arranged electrically separated from each other along each of the first direction (X) and the second direction (Y). For example, each of the multiple vibration parts 511-1, 511-2, 511-3, and 511-4 may be arranged in the form of i×j on the same plane or tiled, so that the vibration element 200 may have a large area by tiling the multiple vibration parts 511-1, 511-2, 511-3, and 511-4 having relatively small sizes. For example, i may be a natural number of 2 or more as the number of vibration parts arranged along the first direction (X), and j may be a natural number of 2 or more that is the same as or different from i as the number of vibration parts arranged along the second direction (Y). For example, each of the multiple vibration parts 511-1, 511-2, 511-3, and 511-4 may be arranged or tiled in a 2×2 format, but the embodiments of the present specification are not limited thereto. In the following description, it is assumed that the vibration element 200 includes the first to fourth vibration parts 511-1, 511-2, 511-3, and 511-4.

[0260] According to an embodiment of the present specification, the first and second vibration parts 511-1, 511-2 may be spaced apart from each other along the first direction (X). The third and fourth vibration parts 511-3, 511-4 may be spaced apart from each other along the first direction (X) and from each other along the second direction (Y).

The second and fourth vibration parts 511-2, 511-4 may face each other and be spaced apart from each other along the second direction (Y).

[0261] The first to fourth vibration units 511-1, 511-2, 511-3, and 511-4 may be disposed between the first cover member 512 and the second cover member 513. For example, the first cover member 512 and the second cover member 513 may connect the first to fourth vibration units 511-1, 511-2, 511-3, and 511-4 or may support them in common, thereby driving the first to fourth vibration units 511-1, 511-2, 511-3, and 511-4 as one vibration device (or a single vibration device). For example, the first to fourth vibration units 511-1, 511-2, 511-3, and 511-4 may be driven as one vibration device (or a single vibration device) by tiling them at regular intervals between the first and second cover members 512 and 513.

[0265] According to an embodiment of the present specification, each of the first to fourth vibrating units 511-1, 511-2, 511-3, and 511-4 may include one of the vibrating layers 511a described with reference to Figures 13 to 16, or may include different vibrating layers 511a. According to another embodiment of the present specification, one or more of the first to fourth vibrating units 511-1, 511-2, 511-3, and 511-4 may include different vibrating layers 511a of the vibrating layers 511a described with reference to Figures 11 to 16.

The first electrode layer 511b is substantially the same as or similar to the first electrode layer 511b described with reference to FIG. 18, so the same reference numerals are used therefor, and redundant description thereof may be omitted or briefly described.

[0267] The second electrode layer 511c may be disposed on a second surface of the vibration layer 511a and electrically connected to the second surface of the vibration layer 511a. The second electrode layer 511c is substantially the same as or similar to the second electrode layer 511c described with reference to FIG. 18, so the same reference numerals are used therefor, and redundant descriptions thereof may be omitted or briefly described.

[0268] According to the embodiment of the present specification, the first and second adhesive layers 514, 515 may be connected or bonded to each other between the first to fourth vibration parts 511-1, 511-2, 511-3, and 511-4. As a result, each of the first to fourth vibration parts 511-1, 511-2, 511-3, and 511-4 may be surrounded by the first and second adhesive layers 514, 515. For example, the first and second adhesive layers 514, 515 may be configured between the first cover member 512 and the second cover member 513 so as to completely surround each of the first to fourth vibration parts 511-1, 511-2, 511-3, and 511-4. For example, each of the first to fourth vibration parts 511-1, 511-2, 511-3, and 511-4 may be embedded or built in between the first adhesive layer 514 and the second adhesive layer 515.

[0269] The vibration element 200 according to another embodiment of the present specification may further include a first power supply line (PL1), a second power supply line (PL2), and a pad portion 518.

[0270] The first power supply line (PL1) and the second power supply line (PL2) are substantially the same as or similar to the first power supply line (PL1) and the second power supply line (PL2) described with reference to Figures 17 and 18, except for the electrical connection structure with the first to fourth vibration parts 511-1, 511-2, 511-3, and 511-4. Therefore, in the following explanation, only the electrical connection structure between the first power supply line (PL1) and the second power supply line (PL2) and the first to fourth vibration parts 511-1, 511-2, 511-3, and 511-4 will be briefly explained.

[0271] The first power supply line (PL1) according to the embodiment of the present specification may include first and second upper power supply lines (PL11, PL12) arranged along the second direction (Y). For example, the first upper power supply line (PL11) may be electrically connected to the first electrode layers 511b of the first and third vibration generating units 511-1, 511-3 arranged in a first row parallel to the second direction (Y) among the first to fourth vibration units 511-1, 511-2, 511-3, 511-4. The second upper power supply line (PL12) may be electrically connected to the first electrode layers 511b of the second and fourth vibration units 511-2, 511-4 arranged in a second row parallel to the second direction (Y) among the first to fourth vibration units 511-1, 511-2, 511-3, 511-4.

[0272] The second power supply line (PL2) according to the embodiment of the present specification may include first and second lower power supply lines (PL21, PL22) arranged along the second direction (Y). For example, the first lower power supply line (PL21) may be electrically connected to the second electrode layers 511c of the first and third vibration generating units 511-1, 511-3 arranged in a first row parallel to the second direction (Y) among the first to fourth vibration units 511-1, 511-2, 511-3, 511-4. The second lower power supply line (PL12) may be electrically connected to the second electrode layers 511c of the second and fourth vibration units 511-2, 511-4 arranged in a second row parallel to the second direction (Y) among the first to fourth vibration units 511-1, 511-2, 511-3, 511-4.

[0273] The pad unit 518 may be configured on one side edge portion of either the first cover member 512 or the second cover member 513 so as to be electrically connected to one side (or one end) of each of the first power supply line (PL1) and the second power supply line (PL2). The pad unit 518 is substantially the same as or similar to the pad unit 518 described with reference to Figures 17 and 18, and therefore the same reference numerals are given thereto, and duplicate descriptions thereof may be omitted or briefly described.

[0274] The vibration element 200 according to other embodiments of this specification has the same or similar effects as the vibration element 200 described with reference to Figures 17 and 18, so duplicate descriptions therefor may be omitted or briefly described.

[0275] Fig. 20 is a diagram showing a vibration element according to another embodiment of the present specification. Fig. 21 is a cross-sectional view taken along line CC' shown in Fig. 20 according to another embodiment of the present specification. Figs. 20 and 21 are diagrams showing another embodiment of the vibration element described with reference to Figs. 1 to 10B.

[0276] 20 and 21, a vibration element 200 according to another embodiment of the present specification may include a plurality of vibration generating units 510A and 510B, and an intermediate member 510m. For example, a vibration element 200 according to another embodiment of the present specification may include a first vibration generating unit 510A, a second vibration generating unit 510B, and an intermediate member 510m between the first vibration generating unit 510A and the second vibration generating unit 510B.

[0277] According to the embodiments of the present specification, the description of FIGS. 20 and 21 may be applied in the same or similar manner to FIGS. 17 to 19.

[0278] The multiple vibration generating units (or the first and second vibration generating units) 510A, 510B may be overlapped or stacked with each other so as to be displaced (or driven or vibrated) in the same direction to maximize the amplitude displacement of the vibration element 200 and / or the amplitude displacement of the vibration member. One side (or end portion or tip or outer surface or each corner portion) of each of the multiple vibration generating units (or the first and second vibration generating units) 510A, 510B may be aligned or positioned on a virtual extension line (VL) extended along the third direction (Z). For example, the first vibration generating unit 510A may be disposed in front of or on the back of the second vibration generating unit 510B.

[0279] Each of the multiple vibration generating units (or first and second vibration generating units) 510A, 510B is any one of the vibration elements 200 described with reference to Figures 11 to 16, so duplicated explanations therefor may be omitted or may be simply described.

[0280] The vibration generating units 510A, 510B may be overlapped or stacked on each other so that they are displaced (or driven or vibrated) in the same direction based on the polarization direction of the vibration layer 511a. For example, when the vibration layers 511a of the first and second vibration generating units 510A, 510B have the same polarization direction, the second vibration generating unit 510B may be disposed on the front or back of the first vibration generating unit 510A. For example, when the vibration layers 511a of the first and second vibration generating units 510A, 510B have opposite polarization directions, the second vibration generating unit 510B may be disposed on the front or back of the first vibration generating unit 510A in an upside-down shape.

[0281] The intermediate member 510m may be disposed or interposed between the multiple vibration generating units 510A and 510B. For example, the intermediate member 510m may be disposed between the second cover member 513 of the first vibration generating unit 510A and the first cover member 512 of the second vibration generating unit 510B. For example, the intermediate member 510m may be made of an adhesive material including an adhesive layer having excellent adhesion or adhesive strength to each of the first vibration generating unit 510A and the second vibration generating unit 510B stacked vertically.

[0282] The intermediate member 510m according to the embodiment of the present specification may include a foam pad, a single-sided tape, a double-sided tape, a single-sided foam pad, a double-sided foam pad, a single-sided foam tape, a double-sided foam tape, or an adhesive, but the embodiment of the present specification is not limited thereto. For example, the adhesive layer of the intermediate member 510m may include an epoxy, an acrylic, a silicone, or a urethane series, but the embodiment of the present specification is not limited thereto. The adhesive layer of the intermediate member 510m may include a urethane series material (or material) having a relatively softer characteristic than acrylic among acrylic and urethane. As a result, in the vibration element 200 according to another embodiment of the present specification, vibration loss due to interference of displacement between the multiple vibration generating units 510A and 510B may be minimized, or each of the multiple vibration generating units 510A and 510B may be freely displaced.

[0283] The intermediate member 510m according to other embodiments of the present specification may include one or more of a heat-curable adhesive, a photo-curable adhesive, and a heat-sealing adhesive. For example, the intermediate member 510m may include a heat-sealing adhesive. The heat-sealing adhesive may be a heat-activated type or a heat-setting type. For example, the intermediate member 510m including the heat-sealing adhesive may bond or bond the two adjacent vibration generating units 510A and 510B to each other by heat and pressure. For example, the intermediate member 510m including the heat-sealing adhesive may minimize or reduce the loss of vibration of the vibration element 200.

[0284] The vibration generating units 510A and 510B may be integrated into one structure (or part) by a lamination process using the intermediate member 510m. For example, the vibration generating units 510A and 510B may be integrated into one structure by a lamination process using a roller.

[0285] 22A to 22D are perspective views showing the laminated structure between the vibration layers of the plurality of vibration generating units shown in FIGS. 10 and 21 according to another embodiment of the present specification.

[0286] 20 and 22A, the vibration layer 511a of each of the vibration generating units 510A and 510B may include a plurality of first portions 511a1 and a plurality of second portions 511a2 disposed between the plurality of first portions 511a1. The vibration layer 511a is substantially the same as or similar to the vibration layer 511a described with reference to FIG. 13, so a duplicated description thereof will be omitted. According to the embodiments of the present specification, the description of FIGS. 22A to 22D may be applied in the same or similar manner to FIGS. 17 to 19.

[0287] The first portion 511a1 of the vibration generating unit 510B arranged in the lower layer among the multiple vibration generating units 510A and 510B and the first portion 511a1 of the vibration generating unit 510A arranged in the upper layer can be substantially overlapped or superimposed on each other without passing each other. The second portion 511a2 of the vibration generating unit 510B arranged in the lower layer among the multiple vibration generating units 510A and 510B and the second portion 511a2 of the vibration generating unit 510A arranged in the upper layer can be substantially overlapped or superimposed on each other without passing each other. As a result, the first portions 511a1 of each of the multiple vibration generating units 510A, 510B are substantially stacked or overlapped on each other without being misaligned with each other, and are displaced (or driven or vibrated) in the same direction as each other, so that the amplitude displacement of the vibration element 200 and / or the amplitude displacement of the vibration member can be increased or maximized by the combined vibration of each of the multiple vibration generating units 510A, 510B, thereby improving the acoustic characteristics and / or sound pressure characteristics in the low-frequency range generated by the vibration of the vibration member.

[0288] 20 and 22B to 22D, the vibration layer 511a of each of the vibration generating units 510A and 510B may include a plurality of first portions 511a1 and a second portion 511a2 that is adjacent to each of the plurality of first portions 511a1 or that is arranged to surround each of the plurality of first portions 511a1. Such a vibration layer 511a is substantially the same as or similar to the vibration layer 511a described with reference to FIGS. 14 to 16, and therefore a duplicate description thereof may be omitted or may be described briefly.

[0289] The first portion 511a1 of the vibration generating unit 510B arranged in the lower layer among the multiple vibration generating units 510A and 510B and the first portion 511a1 of the vibration generating unit 510A arranged in the upper layer can be substantially overlapped or superimposed on each other without being misaligned with each other. The second portion 511a2 of the vibration generating unit 510B arranged in the lower layer among the multiple vibration generating units 510A and 510B and the second portion 511a2 of the vibration generating unit 510A arranged in the upper layer can be substantially overlapped or superimposed on each other without passing each other. As a result, the first portions 511a1 of each of the multiple vibration generating units 510A, 510B are substantially overlapped or superimposed on each other without passing each other and displace (or drive or vibrate) in the same direction as each other, so that the composite vibration of each of the multiple vibration generating units 510A, 510B can increase or maximize the amplitude displacement of the vibration element 200 and / or the amplitude displacement of the vibrating member, thereby improving the acoustic characteristics and / or sound pressure characteristics in the low-frequency range generated by the vibration of the vibrating member.
