Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of and priority to Korean Patent Application No. 10-2021-0194789, filed on December 31, 2021, the entire contents of which are incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to devices for vibration. Background Technology

[0004] The device may include a separate loudspeaker or sound device for providing sound. When a loudspeaker is placed in the device, problems may arise due to the space occupied by the loudspeaker, especially when the design and space arrangement of the device are limited.

[0005] The loudspeaker used in the device can be, for example, an actuator comprising a magnet and a coil. However, when an actuator is used in a device, there is a drawback of its thickness. Therefore, piezoelectric devices for achieving thinner thicknesses have attracted considerable attention.

[0006] Due to their fragile nature, piezoelectric devices are easily damaged by external impacts, resulting in low reliability of sound reproduction. Furthermore, when loudspeakers using piezoelectric devices are applied to flexible devices, their fragility can lead to damage.

[0007] The descriptions provided in the background section should not be construed as prior art simply because they are mentioned in or related to this section. The background section may include information describing one or more aspects of the subject matter art, and the descriptions in this section do not limit the invention. Summary of the Invention

[0008] Therefore, the inventors of this disclosure have recognized the problems and shortcomings of the prior art and have conducted extensive research and experimentation on a vibrating device that can improve sound quality and enhance sound pressure level characteristics. Through extensive research and experimentation, the inventors have invented a device comprising a novel vibrating mechanism that can enhance sound quality and enhance sound pressure level characteristics.

[0009] Therefore, embodiments of this disclosure relate to an apparatus that substantially avoids one or more problems caused by the limitations and disadvantages of the prior art.

[0042] Throughout the accompanying drawings and detailed embodiments, unless otherwise described, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustration, and convenience, the size, length, and thickness of layers, regions, and elements, and their descriptions, may be exaggerated. Detailed Implementation

[0043] Reference will now be made to embodiments of this disclosure in detail, examples of which are illustrated in the accompanying drawings. In the following description, detailed descriptions of well-known functions or configurations may be omitted for brevity where such descriptions might unnecessarily obscure aspects of this disclosure. The described progression of processing steps and / or operations is exemplary; however, the order of steps and / or operations is not limited to the order set forth herein and may be varied, except that they must occur in a specific order.

[0044] Unless otherwise stated, the same reference numerals always refer to the same elements, even if they are shown in different figures. In one or more aspects, the same elements (or elements with the same name) in different figures may have the same or substantially the same function and characteristics. The names of the corresponding elements used in the following description are chosen for convenience only and may therefore differ from the names of elements used in the actual product.

[0045] The advantages and features of this disclosure, and its implementation methods, are illustrated by means of embodiments described with reference to the accompanying drawings. However, this disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are merely examples and are provided to make this disclosure detailed and comprehensive, to assist those skilled in the art in understanding the inventive concept, and do not limit the scope of protection of this disclosure.

[0046] The shapes, sizes, areas, ratios, angles, and numbers disclosed in the accompanying drawings used to describe embodiments of this disclosure are merely examples, and therefore, this disclosure is not limited to the details shown.

[0047] When using terms such as “comprising,” “having,” “including,” “containing,” “constituting,” “composed of,” “formed from,” etc., one or more other elements may be added unless a term such as “only” is used. The terminology used in this disclosure is only for describing particular implementations and is not intended to limit the scope of this disclosure. The terminology used herein is only for describing exemplary implementations and is not intended to limit the scope of this disclosure. Singular terms may include plural forms unless the context clearly indicates otherwise. The word “exemplary” means used as an example or illustration. Implementations are exemplary implementations. Aspects are exemplary aspects. Any implementation described herein as an “example” is not necessarily to be construed as preferred or advantageous relative to other implementations.

[0048] In one or more aspects, a component, feature, or corresponding information (e.g., level, range, size, dimensions, etc.) is interpreted as including a range of errors or tolerances, even if no explicit description of such a range of errors or tolerances is provided. Ranges of errors or tolerances can be caused by various factors (e.g., process factors, internal or external influences, noise, etc.). Furthermore, the use of "can / may" encompasses all the meanings of "able to".

[0049] When describing positional relationships, such as when using terms like "on," "above," "below," "above," "below," "below," "near," "close to," "adjacent," "beside," or "next to" to describe the positional relationship between two parts, one or more other parts may be located between these two parts, unless more restrictive terms such as "immediately adjacent," "directly," or "closely" are used. For example, when a structure is described as being positioned relative to another structure as "on," "above," "below," "above," "below," "below," "near," "close to," "adjacent," "beside," or "next to," this description should be interpreted as including situations where the structures are in contact with each other and where one or more additional structures are set or inserted between them. Furthermore, the terms "front," "back," "behind," "left," "right," "top," "bottom," "down," "upper," "above," "lower," "upper," "lower," "row," "column," "vertical," "horizontal," etc., refer to any frame of reference.

[0050] When describing temporal relationships, when the temporal order is described as such as "after", "following", "next", "before", "in front", "before", etc., it may include discontinuous or non-sequential situations, unless more restrictive terms such as "only", "immediately after", "directly" are used.

[0051] It should be understood that although the terms "first," "second," etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from other elements. For example, a first element may be a second element without departing from the scope of this disclosure, and similarly, a second element may be a first element. Furthermore, first elements, second elements, etc., may be arbitrarily named as appropriate by those skilled in the art without departing from the scope of this disclosure. The terms "first," "second," etc., may be used to distinguish components from each other, but the function or structure of each component is not limited to the serial number or component name preceding the component.

[0052] In describing elements of this disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to distinguish one or more corresponding elements from one or more other elements, and they are not used to define the substance, basis, order, or number of elements.

[0053] When a component or layer is described as being “connected,” “coupled,” or “adhered” to another component or layer, the component or layer may be directly connected, coupled, or adhered to the other component or layer, or indirectly connected, coupled, or adhered to the other component or layer, with one or more intermediate components or layers disposed or inserted between the components or layers, unless otherwise stated.

[0054] Unless otherwise stated, when a component or layer is described as "in contact" or "overlapping" with another component or layer, the component or layer may not only be in direct contact or overlap with another component or layer, but may also be indirect contact or overlap with another component or layer, and one or more intermediate components or layers may be disposed or inserted between these components or layers.

[0055] Terms such as “line” or “direction” should not be interpreted solely based on the geometric relationship that lines or directions are parallel or perpendicular to each other, but can refer to lines or directions that have greater directionality within a certain range in which the components of this disclosure can function properly.

[0056] The term "at least one" should be understood to include any and all combinations of one or more of the associated enumerated items. For example, "at least one of the first, second, and third items" means a combination of two or more items from the first, second, and third items, as well as a combination of only one of the first, second, or third items.

[0057] The expressions "first element," "second element," and " / or" "third element" should be understood as one of the first, second, and third elements, or any or all combinations of the first, second, and third elements. As an example, A, B, and / or C can refer to only A; only B; only C; any or some combinations of A, B, and C; or all of A, B, and C. Furthermore, the expression "element A / element B" can be understood as element A and / or element B.

[0058] In one or more aspects, unless otherwise stated, for convenience, the terms "between" and "among" may be used interchangeably. For example, the expression "between multiple elements" can be understood as "among multiple elements." In another example, the expression "among multiple elements" can be understood as "between multiple elements." In one or more examples, the number of elements may be two. In one or more examples, the number of elements may be more than two.

[0059] In one or more aspects, unless otherwise stated, for convenience, the phrases “each other” and “mutually” may be used interchangeably. For example, the expression “different from each other” can be understood as “different from each other”. In another example, the expression “different from each other” can be understood as “different from each other”. In one or more examples, the number of elements involved in the above expression may be two. In one or more examples, the number of elements involved in the above expression may be more than two.

[0060] In one or more aspects, unless otherwise stated, for convenience, the phrases “one or more of…” and “one or more of…” may be used interchangeably. In one or more aspects, unless otherwise stated, the terms “nth” or “n…” th " can refer to "nnd" or "n" nd (e.g., 2nd, where n is 2), or "nrd" or "n rd (For example, 3rd, where n is 3), and n can be a natural number.

[0061] The apparatus according to one or more embodiments of this disclosure may include, for example, a liquid crystal display (LCD) device or an organic light-emitting display (OLED) device. E D) The display device of the device includes a display panel and a driver for driving the display panel.

[0062] Therefore, in one or more embodiments of this disclosure, examples of the apparatus may include the display device itself, such as an LCD or OLED, as well as kit devices that are end-consumer devices or application products including LCDs or OLEDs.

[0063] In one or more embodiments, an LCD or OLED including a display panel and a driver may be referred to as a display device, and an electronic device that is a final product including an LCD or OLED may be referred to as a kit device. For example, a display device may include a display panel such as an LCD or OLED, and a source printed circuit board (PCB) as a controller for driving the display panel. The kit device may also include a kit PCB as a kit controller electrically connected to the source PCB to control the kit device.

[0064] The display panel used in embodiments of this disclosure can be any type of display panel, such as a liquid crystal display panel, an organic light-emitting diode (OLED) display panel, and an electroluminescent display panel, but is not limited to a specific display panel that is vibrated by a sound generating device according to embodiments of this disclosure to output sound. Furthermore, the shape or size of the display panel used in the display device according to embodiments of this disclosure is not limited.

Furthermore, the display panel may include: an array substrate including thin-film transistors (TFTs) that are switching elements for adjusting the light transmittance of each pixel; an upper substrate including color filters and / or a black matrix; and a liquid crystal layer formed between the array substrate and the upper substrate.

[0066] When the display panel is an organic light-emitting display panel, the display panel may include: multiple gate lines, multiple data lines, and multiple pixels respectively disposed in multiple pixel regions defined by the intersection of the gate lines and the data lines. Furthermore, the display panel may include: an array substrate including thin-film transistors (TFTs), which are elements for selectively applying voltage to each of the pixels; an organic light-emitting device layer on the array substrate; and an encapsulation substrate disposed on the array substrate to cover the organic light-emitting device layer. The encapsulation substrate can protect the TFTs and the organic light-emitting device layer from external impacts and can prevent water or oxygen from penetrating into the organic light-emitting device layer. Additionally, the layers disposed on the array substrate may include inorganic light-emitting layers (e.g., nanoscale material layers, quantum dots, etc.). As another example, the layers disposed on the array substrate may include micro-light-emitting diodes.

[0067] The display panel may also include a backing, such as a metal plate, attached to the display panel. However, this embodiment is not limited to a metal plate, and the display panel may include another structure (e.g., another structure including another material or a different material).

[0068] Features of various embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may operate, link or drive each other in various ways. Embodiments of this disclosure may be performed independently of each other, or may be performed together in a mutually dependent or related relationship.

[0069] In one or more aspects, the components of each device according to various embodiments of the present disclosure are operatively coupled or configured.

[0070] Unless otherwise defined, the terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the exemplary embodiments pertain. It should also be understood that terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with, for example, their meaning in the context of the relevant field, and should not be interpreted ideally or in an overly formal sense, unless otherwise expressly defined herein.

[0071] In the following description, exemplary embodiments of this disclosure are described in detail with reference to the accompanying drawings. Regarding reference numerals for elements in each drawing, the same elements may be shown in other drawings, and the same reference numerals may refer to the same elements unless otherwise specified. Furthermore, for ease of description, the scale, dimensions, size, and thickness of each element shown in the drawings may differ from the actual scale, dimensions, size, and thickness, and therefore embodiments of this disclosure are not limited to the scale, dimensions, size, and thickness shown in the drawings.

[0072] Figure 1 An apparatus according to an embodiment of the present disclosure is shown. Figure 2 It is along Figure 1 A cross-sectional view taken from line A-A'.

[0073] Reference Figure 1 and Figure 2 The apparatus according to embodiments of this disclosure may include a vibrating member 100 and a vibrating device 130 disposed on the rear surface (or rear side surface) of the vibrating member 100. For example, the vibrating member 100 may be a passive vibrating member, a vibrating object, a display panel, a vibrating plate, or a front member, but embodiments of this disclosure are not limited thereto. Hereinafter, one or more embodiments of the vibrating member as a display panel will be described. The vibrating member 100 may have a first surface facing the exterior of the device or exposed to the exterior of the device, and a second surface facing the interior of the device. As used herein, references to the vibrating device 130 disposed on the rear surface of the vibrating member 100 may refer to the vibrating device 130 being disposed on the second surface of the vibrating member 100, or the vibrating device 130 being disposed directly on the second surface, or one or more additional components being disposed between the vibrating device 130 and the vibrating member 100.

[0074] The vibrating member 100 according to embodiments of this disclosure can be a display panel for displaying images. The display panel can display images (e.g., electronic images, digital images, still images, or video images). For example, the display panel can emit light to display images.

[0076] The display panel according to embodiments of this disclosure may include an anode electrode, a cathode electrode, and a light-emitting device, and may display images based on a pixel array layer comprising multiple pixels in a type such as top-emitting, bottom-emitting, or dual-emitting. For the top-emitting type, visible light emitted from the pixel array layer can illuminate the base substrate in a forward direction to allow image display, and for the bottom-emitting type, visible light emitted from the pixel array layer can illuminate the base substrate in a rearward direction to allow image display.

[0077] A display panel according to embodiments of the present disclosure may include a pixel array portion disposed in a pixel region consisting of a plurality of gate lines and / or a plurality of data lines. The pixel array portion may include a plurality of pixels that display an image based on a signal provided through each of the signal lines. The signal lines may include gate lines, data lines, and / or pixel drive power lines, etc., but embodiments of the present disclosure are not limited thereto.

[0078] Each of the plurality of pixels may include a pixel circuit layer comprising: a driving thin-film transistor (TFT) disposed in the pixel region, an anode electrode electrically connected to the driving TFT, a light-emitting device formed on the anode electrode, and a cathode electrode electrically connected to the light-emitting device.

[0079] The driving TFT can be disposed in the transistor region of each pixel region in the substrate. The driving TFT may include a gate electrode, a gate insulating layer, a semiconductor layer, a source electrode, and a drain electrode. The semiconductor layer of the driving TFT may include silicon such as amorphous silicon (a-Si), polycrystalline silicon (poly-Si), or low-temperature polycrystalline silicon, or may include oxides such as indium gallium zinc oxide (IGZO), but embodiments of this disclosure are not limited thereto.

[0080] The anode electrode (or pixel electrode) can be disposed in an opening region in each pixel region and can be electrically connected to the driving TFT.

[0081] The light-emitting device according to embodiments of this disclosure may include a light-emitting device layer disposed on an anode electrode. The light-emitting device layer may be implemented such that pixels emit light of the same color (e.g., white light) or emit light of different colors (e.g., red, green, and blue light). A cathode electrode (or common electrode) may be connected to the light-emitting device layer disposed in each pixel region. For example, the light-emitting device layer may have a stacked structure comprising two or more structures or a single structure comprising the same color.

[0082] In another embodiment of this disclosure, the light-emitting device layer may have a stacked structure comprising two or more structures, each comprising one or more different colors for each pixel. The two or more structures comprising one or more different colors may be configured as one or more of blue, red, yellow-green, and green, or combinations thereof, but embodiments of this disclosure are not limited thereto. Examples of combinations may include blue and red, red and yellow-green, red and green, red / yellow-green / green, etc., but embodiments of this disclosure are not limited thereto. Furthermore, this combination can be applied regardless of its stacking order. The stacked structure comprising two or more structures having the same color or one or more different colors may also include a charge generation layer between the two or more structures. The charge generation layer may have a PN junction structure and may include an N-type charge generation layer and a P-type charge generation layer.

[0083] According to another embodiment of this disclosure, the light-emitting device may include a miniature light-emitting diode (LED) device electrically connected to each of the anode electrode and the cathode electrode. The miniature LED device may be an LED implemented as an integrated circuit (IC) or a chip-type LED. The miniature LED device may include a first terminal electrically connected to the anode electrode and a second terminal electrically connected to the cathode electrode. The cathode electrode may be connected to the second terminal of the miniature LED device disposed in each pixel region.

[0084] An encapsulation portion can be formed on a substrate to surround the pixel array portion, and thus, oxygen or water can be prevented from penetrating into the light-emitting device layer of the pixel array portion. The encapsulation portion according to embodiments of this disclosure can be formed as a multilayer structure with alternating stacked organic and inorganic material layers, but embodiments of this disclosure are not limited thereto. The inorganic material layer prevents oxygen or water from penetrating into the light-emitting device layer of the pixel array portion. The organic material layer can be formed to have a thickness relatively thicker than the inorganic material layer to cover particles generated during the manufacturing process. For example, the encapsulation portion may include a first inorganic layer, an organic layer on the first inorganic layer, and a second inorganic layer on the organic layer. The organic layer may be a particle covering layer, but embodiments of this disclosure are not limited thereto. A touch panel can be disposed on or at the encapsulation portion, or it can be disposed on or at the rear surface of the pixel array portion or within the pixel array portion.

[0085] The display panel according to embodiments of this disclosure may include a first substrate, a second substrate, and a liquid crystal layer. The first substrate may be an upper substrate or a TFT array substrate. For example, the first substrate may include a pixel array (or display section or display area), the pixel array including a plurality of pixels disposed in a pixel area composed of a plurality of gate lines and / or a plurality of data lines. Each of the plurality of pixels may include: a TFT connected to the gate lines and / or data lines, a pixel electrode connected to the TFT, and a common electrode formed adjacent to the pixel electrode and provided with a common voltage.

[0086] The first substrate may further include a pad portion disposed on its first edge (or non-display portion or first periphery) and a gate driving circuit disposed on its second edge (or second non-display portion or second periphery).

[0087] The pad portion can provide signals supplied from the outside to the pixel array portion and / or the gate drive circuit. For example, the pad portion may include multiple data pads connected to multiple data lines via multiple data link lines and / or multiple gate input pads connected to the gate drive circuit via gate control signal lines. For example, the size of the first substrate may be larger than the size of the second substrate, but embodiments of this disclosure are not limited thereto.

[0088] The gate driving circuit can be embedded (or integrated) into the second edge (or second periphery) of the first substrate to be connected to multiple gate lines. For example, the gate driving circuit can be implemented using a shift register comprising transistors formed using the same process as the TFTs disposed in the pixel region. According to another embodiment of this disclosure, the gate driving circuit may not be embedded in the first substrate and can be disposed in an IC-type panel driving circuit.

[0089] The second substrate can be a lower substrate or a color filter array substrate. For example, the second substrate may include a pixel pattern (or pixel-defined pattern) capable of including an opening region overlapping a pixel region formed in the first substrate and a color filter layer formed in the opening region. The second substrate may have a smaller size than the first substrate, but embodiments of this disclosure are not limited thereto. The second substrate may overlap with a portion of the first substrate other than the first edge (or first periphery). The second substrate may be bonded (or attached) to a portion of the first substrate other than the first edge (or first periphery) by a sealant, wherein the liquid crystal layer is located between the first substrate and the second substrate.

[0090] A liquid crystal layer may be disposed between a first substrate and a second substrate. The liquid crystal layer may include liquid crystal, wherein the alignment orientation of the liquid crystal molecules is changed based on an electric field generated by the data voltage and a common voltage applied to the pixel electrode of each pixel.

[0091] The second polarizing member can be attached to the bottom surface (or lower surface) of the second substrate and can polarize the light incident from the backlight and traveling to the liquid crystal layer. The first polarizing member can be attached to the top surface (or upper surface) of the first substrate and can polarize the light passing through the first substrate and output to the outside.

[0092] The display panel according to embodiments of this disclosure can drive the liquid crystal layer using an electric field generated by the data voltage applied to each pixel and a common voltage, thereby displaying an image based on light passing through the liquid crystal layer.

[0093] In another embodiment of the display panel according to this disclosure, the first substrate may be a color filter array substrate, and the second substrate may be a TFT array substrate. For example, the display panel according to another embodiment of the present disclosure may have a form in which the display panel according to the embodiment of the present disclosure is vertically inverted. In this case, the pad portion of the display panel according to another embodiment of the present disclosure may be covered by a separate mechanism (or structure).

[0094] A display panel according to another embodiment of the present disclosure may include a bent portion that is bent or flexed to have a specific radius of curvature or a curved shape.

The edge portion (or peripheral portion) and the other edge portion (or another peripheral portion) of the display panel implementing the bent portion can include only the non-display area IA, or can include the display area AA and the edge portion (or peripheral portion) of both the display area IA and the non-display area IA. The display panel including the bent portion implemented by bending the non-display area IA can have a one-sided bezel bending structure or a double-sided bezel bending structure. Furthermore, the display panel including the edge portion (or peripheral portion) of the display area AA and the bent portion implemented by bending the non-display area IA can have a one-sided active bending structure or a double-sided active bending structure.

[0098] Vibration device 130 can cause vibration member 100 to vibrate. For example, vibration device 130 can be implemented on the rear surface of vibration member 100 to directly cause vibration member 100 to vibrate. For example, vibration device 130 can cause vibration member 100 to vibrate at the rear surface of vibration member 100, and thus can provide sound and / or tactile feedback to the user based on the vibration of vibration member 100. For example, vibration member 100 can output sound based on the vibration of vibration device 130. Vibration device 130 can output sound through vibration member 100 as a diaphragm. For example, vibration device 130 can output sound towards the front surface of vibration member 100 through vibration member 100 as a diaphragm. For example, vibration device 130 can generate sound such that the sound travels towards the front surface of display panel or each of vibration member 100. Vibration device 130 can cause vibration member 100 to vibrate to output sound. For example, vibration device 130 can directly cause vibration member 100 to vibrate to output sound. For example, the vibration member 100 may be (or may include) a vibration object, a vibration plate, or a front member, but the embodiments of this disclosure are not limited thereto.

[0099] According to embodiments of this disclosure, the vibration device 130 can vibrate based on a vibration drive signal synchronized with an image displayed by the display panel, which serves as a vibration member 100, thereby causing the display panel to vibrate. According to another embodiment of this disclosure, the vibration device 130 can vibrate based on a tactile feedback signal (or haptic feedback signal) synchronized with a user touch applied to a touch panel (or touch sensor layer) disposed on or embedded in the display panel, and thus, the display panel can vibrate. Therefore, the display panel can vibrate based on the vibration of the vibration device 130 to provide one or more of auditory and tactile feedback to the user (or viewer).

[0100] The vibration device 130 according to embodiments of this disclosure can be implemented with a size corresponding to the size of the vibrating member 100 or the display area AA of the display panel. The size of the vibration device 130 can be 0.9 to 1.1 times the size of the vibrating member 100 or the display area AA, but embodiments of this disclosure are not limited thereto. For example, the size of the vibration device 130 can be less than or equal to the size of the vibrating member 100 or the display area AA. For example, the size of the vibration device 130 can be equal to or almost equal to the size of the vibrating member 100 or the display area AA of the display panel, and therefore, a large area of ​​the display panel or the vibrating member 100 can be covered, and the vibration generated by the vibration device 130 can cause the entire (all) area of ​​the display panel or the vibrating member 100 to vibrate, thereby improving user satisfaction and increasing the sound localization. Furthermore, the contact area (or panel coverage) between the display panel or the vibrating member 100 and the vibration device 130 can be increased, and therefore, the vibration area of ​​the display panel or the vibrating member 100 can be increased, thereby enhancing the sound of the mid-to-low pitch bands generated by the vibration of the display panel or the vibrating member 100. Furthermore, the vibration device 130 applied to a large-size device can vibrate all display panels or vibration members 100 having a large size (or large area), and thus, the localization of sound based on the vibration of the display panel or vibration member 100 can be further enhanced, thereby achieving an enhanced sound effect. Therefore, the vibration device according to the embodiments of the present disclosure can be arranged on or at the rear surface of the display panel or vibration member 100 to sufficiently vibrate the display panel or vibration member 100 in the vertical (or forward and backward) direction, thereby outputting the desired sound in the forward direction of the device.

[0101] The vibration device 130 can be implemented as a membrane type, and therefore can have a thickness thinner than the display panel or the vibrating member 100, thereby minimizing the increase in device thickness caused by the arrangement of the vibration device 130. For example, the vibration device 130 can use the display panel or the vibrating member 100 as a sound diaphragm. For example, the vibration device 130 according to the embodiments of this disclosure can be referred to as a vibration generating device, a displacement device, a sound device, a sound generating module, a sound generating apparatus, a membrane actuator, a membrane piezoelectric composite actuator, a membrane loudspeaker, a membrane piezoelectric loudspeaker, or a membrane piezoelectric composite loudspeaker, but the terminology is not limited thereto. According to another embodiment of this disclosure, the vibration device 130 may not be arranged on the rear surface of the display panel 100, and may be applied to non-display panels instead of display panels. For example, the vibration device 130 may be applied to one or more of the following: wood, plastic, glass, metal, fabric, fiber, rubber, paper, mirrors, leather, interior materials of motor vehicles, ceilings of buildings, and aircraft, but the embodiments of this disclosure are not limited thereto. In this case, the non-display panel can be used as a vibrating plate, and the vibration device 130 can vibrate the non-display panel to output sound.

[0102] According to embodiments of the present disclosure, the vibration device 130 may be arranged in or on the rear surface of the display panel or the vibration member 100, overlapping with the display area of ​​the display panel or the vibration member 100. For example, the vibration device 130 may overlap with the vibration member 100 or with a display area corresponding to half or more of the display area of ​​the display panel. According to another embodiment of the present disclosure, the vibration device 130 may overlap with the entire (or all) display area of ​​the display panel or the entire vibration member 100.

[0103] According to another embodiment of this disclosure, the vibrating member 100 may include a plate 101. The plate 101 may include a metallic material, or it may include a single non-metallic material or a composite non-metallic material. The single non-metallic material or the composite non-metallic material includes one or more of the following: wood, plastic, glass, fabric, fiber, rubber, paper, mirror, and leather, but the embodiments of this disclosure are not limited thereto.

[0104] When an alternating current (AC) voltage is applied, the vibration device 130 according to embodiments of the present disclosure can alternately contract and expand based on the inverse piezoelectric effect, and can vibrate the vibration member 100 or the display panel based on the vibration. According to embodiments of the present disclosure, the vibration device 130 can vibrate the display panel based on a voice signal synchronized with the image displayed on the display panel. According to another embodiment of the present disclosure, the vibration device 130 can vibrate based on a tactile feedback signal (or haptic feedback signal) synchronized with a user touch applied to a touch panel (or touch sensor layer) disposed on or embedded in the display panel, and therefore, can vibrate the display panel. Thus, the display panel can vibrate based on the vibration of the vibration device 130 to provide one or more of auditory and tactile feedback to the user (or viewer).

[0105] Therefore, the apparatus according to embodiments of the present disclosure can output sound generated by the vibration of the display panel or the vibration member 100 based on the vibration of the vibration device 130 in the forward direction of the display panel or the vibration member 100. Furthermore, the apparatus according to embodiments of the present disclosure can further enhance the sound localization and sound pressure level characteristics of the sound based on the vibration of the vibration member 100 (or the display panel) by causing a large area of ​​the vibration member 100 (or the display panel) to vibrate using the diaphragm-type vibration device 130.

[0106] The apparatus according to embodiments of the present disclosure may further include a connecting member 150 (or a first connecting member) between the vibration device 130 and the vibration member 100.

[0107] For example, the connecting member 150 may be arranged between the vibrating device 130 and the rear surface (or rear side surface) of the vibrating member 100. For example, the vibrating device 130 may be connected or coupled to the rear surface of the vibrating member 100 by the connecting member 150, and therefore may be supported by or arranged on the rear surface of the vibrating member 100.

[0108] The connecting member 150 according to embodiments of this disclosure may include a material comprising an adhesive layer having relatively strong adhesion or bonding force to the rear surface of the vibrating member 100 and each of the vibrating devices 130. For example, the connecting member 150 may include a foam pad, double-sided tape, double-sided foam pad, double-sided foam tape, or adhesive, but embodiments of this disclosure are not limited thereto. For example, the adhesive layer of the connecting member 150 may include epoxy resin, acrylic resin, silicone resin, or urethane, but embodiments of this disclosure are not limited thereto. For example, the adhesive layer of the connecting member 150 may include an acryloyl-based material, which has stronger adhesion and higher hardness compared to urethane-based materials. Therefore, vibrations from the vibrating device 130 can be efficiently transmitted to the vibrating member 100.

[0109] The adhesive layer of the connecting member 150 may also include additives, such as tackifiers, wax components, or antioxidants, but embodiments of this disclosure are not limited thereto. Additives can prevent the connecting member 150 from separating (peeling off) from the vibrating member 100 due to vibration of the vibrating device 130. For example, the tackifier may be a rosin derivative, the wax component may be paraffin, and the antioxidant may be a phenol-based antioxidant such as a thioester, but embodiments of this disclosure are not limited thereto.

[0110] According to another embodiment of this disclosure, the connecting member 150 may further include a hollow portion disposed between the vibrating device 130 and the vibrating member 100. The hollow portion of the connecting member 150 can provide an air gap between the vibrating device 130 and the vibrating member 100. Based on this air gap, the sound waves (or sound pressure level) generated by the vibration of the vibrating device 130 may not be dispersed by the connecting member 150 and may be concentrated on the vibrating member 100. Therefore, the loss of vibration based on the connecting member 150 can be minimized, thereby increasing the sound pressure level characteristics and / or sound characteristics of the sound generated by the vibration of the vibrating member 100.

[0111] The apparatus according to embodiments of the present disclosure may further include a support member 300 disposed on the rear surface (or rear side surface) of the vibrating member 100.

[0112] The support member 300 may be arranged on the rear surface of the vibrating member 100 or the display panel.

For example, the support member 300 may cover the entire rear surface of the vibrating member 100 or the display panel, with a gap space GS therebetween. The support member 300 may be spaced apart from the rearmost surface of the display panel or the vibrating member 100, with a gap space GS therebetween, or it may be spaced apart from the vibration device 130. For example, the gap space GS may be referred to as an air gap, a vibration space, or a sound box, but the terminology is not limited thereto.

[0113] For example, the support member 300 may include one or more of glass, metal, and plastic materials. For example, the support member 300 may be a rear structure, a setting structure, a support structure, a support cover, a rear member, a shell, or a housing, but the terminology is not limited thereto. The support member 300 may be referred to by other terms such as cover bottom, plate bottom, rear cover, base frame, metal frame, metal chassis, chassis base, intermediate chassis, etc. For example, the support member 300 may be implemented as any type of frame or plate structure arranged on the rear surface of the vibrating member 100.

[0114] The edges or sharp corners (or peripheries) of the support member 300 may be beveled or curved by chamfering or rounding. For example, the glass material of the support member 300 may be sapphire glass. In another embodiment of this disclosure, the support member 300, which includes a metallic material, may include one or more of the following: aluminum (Al), aluminum alloys, magnesium (Mg) alloys, and iron (Fe)-nickel (Ni) alloys.

[0115] The support member 300 according to embodiments of this disclosure may include a first support member 310 and a second support member 330.

[0116] The first support member 310 may be disposed between the second support member 330 and the rear surface of the display panel or vibrating member 100. For example, the first support member 310 may be disposed between the front edge (or front periphery) of the second support member 330 and the rear edge (or rear periphery) of the display panel or vibrating member 100. The first support member 310 may support one or more of the edge portions (or periphery portions) of the second support member 330 and the edge portions (or periphery portions) of the display panel or vibrating member 100. In another embodiment of this disclosure, the first support member 310 may cover the rear surface of the display panel or vibrating member 100. For example, the first support member 310 may cover the entire (or all) rear surface of the display panel or vibrating member 100. For example, the first support member 310 may be a member that covers the entire rear surface of the display panel or vibrating member 100.

For example, the first support member 310 may be an inner plate, a first rear structure, a first support structure, a first support cover, a first back cover, a first rear member, an inner plate, or an inner cover, but the embodiments of this disclosure are not limited thereto. For example, the first support member 310 may be omitted.

[0117] The first support member 310 may be spaced apart from the rearmost surface of the vibrating member 100, having a gap space GS therebetween, or it may be spaced apart from the vibrating device 130. For example, the gap space GS may be referred to as an air gap, a vibration space, and a sound box, but the embodiments of this disclosure are not limited thereto.

[0118] The second support member 330 may be disposed on or on the rear surface of the first support member 310. The second support member 330 may cover the entire (or all) rear surface of the display panel or the vibration member 100.

[0119] The support member 300 according to the embodiments of this disclosure may further include a connecting member 350 (or a second connecting member).

[0120] The connecting member 350 may be disposed between the first support member 310 and the second support member 330. For example, the first support member 310 may be coupled to or connected to the second support member 330 by the connecting member 350. For example, the connecting member 350 may be an adhesive resin, double-sided tape, or double-sided foam tape, but embodiments of the present disclosure are not limited thereto. For example, the connecting member 350 may have elasticity for shock absorption, but embodiments of the present disclosure are not limited thereto. For example, the connecting member 350 may be disposed over the entire (or all) region or the entire (or all) region between the first support member 310 and the second support member 330. In another embodiment of the present disclosure, the connecting member 350 may be formed as a mesh structure including an air gap between the first support member 310 and the second support member 330.

[0121] The apparatus according to embodiments of this disclosure may further include an intermediate frame 400. The intermediate frame 400 may be disposed between the rear edge (or rear periphery) of the display panel or vibrating member 100 and the front edge (or front periphery) of the support member 300. The intermediate frame 400 may support one or more of the edge portions (or periphery) of the display panel and the edge portions (or periphery) of the support member. The intermediate frame 400 may surround one or more side surfaces of each of the display panel and the support member 300. The intermediate frame 400 may provide a clearance space GS between the display panel and the support member 300. The intermediate frame 400 may be referred to as an intermediate housing, intermediate cover, intermediate chassis, connecting member, frame, frame member, intermediate member, or side cover member, but embodiments of this disclosure are not limited thereto.

[0122] The intermediate frame 400 according to embodiments of the present disclosure may include a first support portion 410 and a second support portion 430. For example, the first support portion 410 may be a support portion, but embodiments of the present disclosure are not limited thereto. For example, the second support portion 430 may be a sidewall portion, but embodiments of the present disclosure are not limited thereto.

[0123] The first support portion 410 can be arranged between the rear edge (or rear periphery) of the display panel or vibrating member 100 and the front edge (or front periphery) of the support member 300, and thus, a gap space GS can be provided between the display panel or vibrating member 100 and the support member 300. The front surface of the first support portion 410 can be connected or attached to the rear edge (or rear periphery) of the display panel or vibrating member 100 by a first adhesive member 401. The rear surface of the first support portion 410 can be connected or attached to the front edge (or front periphery) of the support member 300 by a second adhesive member 403. For example, the first support portion 410 can have a single frame structure with a quadrilateral shape or multiple frame structures with a segmented shape, but the embodiments of this disclosure are not limited thereto.

[0124] The second support portion 430 may be arranged parallel to the thickness direction Z of the device. For example, the second support portion 430 may be vertically connected to the outer surface of the first support portion 410 parallel to the thickness direction Z of the device. The second support portion 430 may surround one or more of the outer surfaces of the vibrating member 100 and the support member 300, thereby protecting the outer surfaces of each of the vibrating member 100 and the support member 300. The first support portion 410 may protrude from the inner surface of the second support portion 430 into the gap space GS between the vibrating member 100 and the support member 300.

[0125] An apparatus according to an embodiment of this disclosure may include a panel connecting member (or connecting member) in place of the intermediate frame 400.

[0126] A panel connecting member can be disposed between the rear edge (or rear periphery) of the vibrating member 100 and the front edge (or front periphery) of the support member 300, thus providing a gap space GS between the vibrating member 100 and the support member 300. The panel connecting member can be disposed between the rear edge (or rear periphery) of the vibrating member 100 and the front edge (or front periphery) of the support member 300, and can attach the vibrating member 100 to the support member 300. For example, the panel connecting member can be implemented using double-sided tape, single-sided tape, or double-sided foam tape, but embodiments of this disclosure are not limited thereto. For example, the adhesive layer of the panel connecting member can include epoxy resin, acrylic resin, silicone resin, or urethane, but embodiments of this disclosure are not limited thereto. For example, to minimize the transmission of vibrations from the vibrating member 100 to the support member 300, the adhesive layer of the panel connecting member can include an acrylamide-based material, which has stronger adhesion and higher hardness compared to urethane-based materials. Therefore, the vibration transmitted to the display panel or the vibration member 100 to the support member 300 can be minimized.

[0127] In the apparatus according to embodiments of the present disclosure, where a panel connecting member is provided instead of the intermediate frame 400, the support member 300 may include a bent sidewall that bends from one side (or end or portion) of the second support member 330 to surround one or more of the outer surfaces (or outer sidewalls) of the first support member 310, the panel connecting member, and the vibration member 100. The bent sidewall according to embodiments of the present disclosure may have a single sidewall structure or a rolled edge structure. A rolled edge structure may be a structure in which the end portion of any member is bent into a curved shape and overlaps or is spaced parallel to another portion. For example, to enhance the aesthetics of the side surface in the design, the bent sidewall may include a first bent sidewall bent from one side (or end or portion) of the second support member 330 and a second bent sidewall bent from the first bent sidewall to the region between the first bent sidewall and the outer surface of the vibration member 100. The second bent sidewall may contact the inner surface of the first bent sidewall, or may be spaced apart from the inner surface of the first bent sidewall to reduce the transmission of external impacts in the lateral direction to the outer surface of the vibrating member 100. Therefore, the second bent sidewall can reduce the contact between the outer surface of the vibrating member 100 and the inner surface of the first bent sidewall, or reduce the transmission of external impacts in the lateral direction to the outer surface of the vibrating member 100.

[0128] According to another embodiment of this disclosure, the intermediate frame 400 may be omitted. Instead of the intermediate frame 400, panel connecting members or adhesives may be provided. According to another embodiment of this disclosure, instead of the intermediate frame 400, a separator may be provided.

[0129] Because the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords are reduced when the vibrating device 130 is configured as a diaphragm vibrating device, the inventors have conducted extensive research and experiments to improve the sound pressure level characteristics of the low-pitched vocal cords. Through extensive research and experiments, the inventors have invented a device comprising a new structure for enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords. This will be described below.

[0130] Figures 3A to 3C A vibration device according to an embodiment of the present disclosure is shown.

[0131] Reference Figures 3A to 3CThe vibration device 130 according to embodiments of this disclosure may include a first vibration part 131 and a second vibration part 132. For example, the first vibration part 131 may be configured as (or may include) one or more first vibration parts. For example, the second vibration part 132 may be configured as (or may include) a plurality of second vibration parts. The plurality of second vibration parts may differ from one or more first vibration parts. For example, one or more of the shape, size, material, material properties, or sound output characteristics of the plurality of second vibration parts may differ from one or more first vibration parts.

[0132] According to embodiments of this disclosure, the first vibration part 131 may include a material having a polycrystalline structure, and the second vibration part 132 may include a material having a single-crystal structure. For example, the first vibration part 131 may include polycrystalline ceramic, and the second vibration part 132 may include single-crystal ceramic.

[0133] For example, the first vibrating part 131 can be a polycrystalline vibrating part, and the second vibrating part 132 can be a monocrystalline vibrating part. For example, the first vibrating part 131 can include irregular particles in which various crystal domains are disposed. For example, the second vibrating part 132 can have a structure in which particles of monocrystalline domains with a specific structure are regularly arranged. Because the first vibrating part 131 is about two or three times smaller than the second vibrating part 132 in terms of vibration characteristics, there may be a problem of reduced sound pressure level characteristics of the low-pitched vocal cords. However, the vibrating device 130 can be manufactured with a large area, thereby realizing a large-size vibrating device or sound device. The second vibrating part 132 can be manufactured with vibration characteristics (e.g., piezoelectric deformation constant "d") that are significantly smaller than the second vibrating part 132. 33 "It is larger in the thickness direction Z; or, for example, the piezoelectric deformation constant 'd'." 33 "A vibration device that is two or three times larger (in the thickness direction Z) than the first vibrating part 131, and therefore, can have higher sound pressure level characteristics (or sound characteristics) in the low-pitched vocal cords. Therefore, the inventors conducted extensive research and experiments using the second vibrating part 132 to improve the sound pressure level characteristics and / or sound characteristics of the low-pitched vocal cords produced when the vibration device is implemented using the first vibrating part 131. Through extensive research and experiments, the inventors invented a vibration device including the first vibrating part 131 and the second vibrating part 132. This will be described in more detail below."

[0134] The vibration device 130 according to embodiments of this disclosure can vibrate by alternately and repeatedly contracting and expanding based on the piezoelectric effect (or piezoelectric properties). The vibration device 130 according to embodiments of this disclosure can vibrate in the thickness direction Z by alternately and repeatedly contracting and expanding based on the inverse piezoelectric effect or the piezoelectric effect, and therefore, can cause the vibration member 100 or the display panel to vibrate. For example, the vibration device 130 can be a vibrating diaphragm, a displacement generator, a displacement membrane, a sound generator, a vibration array, a vibration array portion, a vibration structure array portion, or a vibration array structure, but embodiments of this disclosure are not limited thereto.

[0135] Each of the first vibrating part 131 and the second vibrating part 132 may include a piezoelectric material, a composite piezoelectric material, or an electroactive material that incorporates the piezoelectric effect. Each of the first vibrating part 131 and the second vibrating part 132 may be referred to by terms such as piezoelectric vibrating part, piezoelectric vibrating layer, displacement part, piezoelectric displacement part, piezoelectric displacement layer, sound wave generating part, vibrating layer, piezoelectric material layer, piezoelectric composite layer, electroactive layer, piezoelectric material part, electroactive part, piezoelectric structure, piezoelectric composite layer, piezoelectric composite, or piezoelectric ceramic composite. However, the terminology is not limited thereto.

[0136] For example, each of the first vibrating part 131 and the second vibrating part 132 may include a ceramic matrix material for generating relatively high vibrations, and / or may include a piezoelectric ceramic having a perovskite-based crystal structure. The perovskite crystal structure may have a piezoelectric effect and / or an inverse piezoelectric effect, and may be an oriented plate-like structure. The perovskite crystal structure may be represented by the chemical formula "ABO3". In the chemical formula, "A" may include a divalent metal element, and "B" may include a tetravalent metal element. For example, in the chemical formula "ABO3", "A" and "B" may be cations, and "O" may be an anion. For example, the first vibrating part 131 and the second vibrating part 132 may include one or more of lead(II) titanate (PbTiO3), lead zirconate (PbZrO3), lead zirconate titanate (PbZrTiO3), barium titanate (BaTiO3), and strontium titanate (SrTiO3), but embodiments of this disclosure are not limited thereto.

[0137] In perovskite crystal structures, the position of the central ion can be altered by external stress or a magnetic field to change the polarization, and a piezoelectric effect can be generated based on this change in polarization. In perovskite crystal structures including PbTiO3, the position of the Ti ion corresponding to the central ion can be changed to alter the polarization, and thus, a piezoelectric effect can be generated. For example, in perovskite crystal structures, a cubic shape with a symmetrical structure can be changed into a quadrilateral shape, an orthorhombic shape, and a rhombic shape with an asymmetrical structure by external stress or a magnetic field, and thus, a piezoelectric effect can be generated. The polarization can be high at the morphotropic phase boundary (MPB) of the quadrilateral and rhombic structures, and the polarization can be easily realigned, thereby obtaining high piezoelectric properties.

[0138] According to embodiments of the present disclosure, the inorganic material portion included in each of the first vibration portion 131 and the second vibration portion 132 may include one or more of the following materials: lead (Pb), zirconium (Zr), titanium (Ti), zinc (Zn), nickel (Ni), and niobium (Nb), but embodiments of the present disclosure are not limited thereto.

[0139] According to another embodiment of this disclosure, the inorganic material portion in each of the first vibration section 131 and the second vibration section 132 may include a material based on lead zirconate titanate (PZT), including lead (Pb), zirconium (Zr), and titanium (Ti); or may include a material based on lead nickel niobate (PZNN), including lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb), but the embodiments of this disclosure are not limited thereto. According to another embodiment of this disclosure, the inorganic material portion may include a material based on lead magnesium niobate (PMN), a material based on lead nickel niobate (PNN), a material based on lead zirconate niobate (PZN), or a material based on lead indium niobate (PIN), but the embodiments of this disclosure are not limited thereto. The PMN-based material may include Pb, Mg, and Nb, and may include, for example, Pb(Mg,Nb)O3. The PNN-based material may include Pb, Ni, and Nb, and may include, for example, Pb(Ni,Nb)O3. PIN-based materials may include Pb, In, and Nb, and may include, for example, Pb(In,Nb)O3. According to another embodiment of this disclosure, the inorganic material portion included in each of the first vibration portion 131 and the second vibration portion 132 may include one or more of calcium titanate (CaTiO3), BaTiO3, and SrTiO3, each excluding Pb, but embodiments of this disclosure are not limited thereto.

[0140] According to another embodiment of this disclosure, the inorganic material portion included in each of the first vibration portion 131 and the second vibration portion 132 may have a piezoelectric deformation coefficient "d" of 1000 pC / N or greater in the thickness direction Z. 33 "Through the high piezoelectric deformation coefficient "d 33 This provides a device that can be applied to display panels or vibrating components (or vibrating objects) of large size, or that possesses sufficient vibrational or piezoelectric properties. For example, to achieve a high-voltage deformation coefficient "d" 33 The inorganic material component may include PZT-based materials (PbZrTiO3) as the main component, and may include softening dopant materials doped into the A site (Pb) and relaxor ferroelectric materials doped into the B site (ZrTi).

[0141] Softener dopants can enhance the piezoelectric and dielectric properties of inorganic material components, and, for example, can increase the piezoelectric deformation coefficient "d" of the inorganic material components. 33 When the softening agent dopant material includes a divalent element "+1", the piezoelectric and dielectric properties of the inorganic material portion can be reduced. For example, when the softening agent dopant material includes potassium (K) and rubidium (Rb), the piezoelectric and dielectric properties of the inorganic material portion can be reduced. The softening agent dopant material according to embodiments of this disclosure can include divalent elements "+2" to trivalent elements "+3". Quasi-isomorphic phase boundaries (MPBs) can be achieved by adding softening agent dopant materials to PZT-based materials (PbZrTiO3), and thus, piezoelectric and dielectric properties can be enhanced. For example, the softening agent dopant material can include one or more of strontium (Sr), barium (Ba), lanthanum (La), neodymium (Nd), calcium (Ca), yttrium (Y), erbium (Er), or ytterbium (Yb). For example, the softening agent dopant material ions (e.g., Sr) doped into PZT-based materials (PbZrTiO3) 2+ Ba 2+ La 2+ 、Nd 3+ Ca 2+ Y 3+ Er 3+ and Yb 3+ This material can replace a portion of the lead (Pb) in PZT-based materials (PbZrTiO3), with a substitution rate ranging from approximately 2 mol% to approximately 20 mol%. For example, when the substitution rate is less than 2 mol% or greater than 20 mol%, the perovskite crystal structure may be disrupted, and therefore, the electromechanical coupling coefficient "kP" and the piezoelectric deformation coefficient "d" may be reduced. 33When the softener dopant material is replaced, an MPB can be formed, and the piezoelectric and dielectric properties of the MPB can be high, thereby realizing a vibration device with high piezoelectric and high dielectric properties.

[0142] According to embodiments of this disclosure, relaxor ferroelectric materials doped into PZT-based materials (PbZrTiO3) can enhance the electrical deformation properties of the inorganic material portion. The relaxor ferroelectric materials according to embodiments of this disclosure may include PMN-based materials, PNN-based materials, PZN-based materials, or PIN-based materials, but embodiments of this disclosure are not limited thereto. PMN-based materials may include Pb, Mg, and Nb, and may include, for example, Pb(Mg,Nb)O3. PNN-based materials may include Pb, Ni, and Nb, and may include, for example, Pb(Ni,Nb)O3. PZN-based materials may include Pb, Zr, and Nb, and may include, for example, Pb(Zr,Nb)O3. PIN-based materials may include Pb, In, and Nb, and may include, for example, Pb(In,Nb)O3. For example, relaxor ferroelectric materials doped into PZT-based materials (PbZrTiO3) can replace a portion of each of zirconium (Zr) and titanium (Ti) in the PZT-based materials (PbZrTiO3), and the substitution rate can be from about 5 mol% to about 25 mol%. For example, when the substitution rate is less than 5 mol% or greater than 25 mol%, the perovskite crystal structure may be destroyed, and therefore, the electromechanical coupling coefficient “kP” and the piezoelectric deformation coefficient “d” may be reduced. 33 ".

[0143] According to embodiments of this disclosure, the inorganic material portion included in each of the first vibrating portion 131 and the second vibrating portion 132 may further include donor materials doped into the B-sites (ZrTi) of the PZT-based material (PbZrTiO3) to further enhance the piezoelectric coefficient. For example, the donor materials doped into the B-sites (ZrTi) may include tetravalent elements "+4" or hexavalent elements "+6". For example, the donor materials doped into the B-sites (ZrTi) may include one or more of tellurium (Te), germanium (Ge), uranium (U), bismuth (Bi), niobium (Nb), tantalum (Ta), antimony (Sb), or tungsten (W).

[0144] According to embodiments of this disclosure, compared to the first vibrating part 131, the second vibrating part 132 may have a larger electromechanical coupling coefficient "kP" and a higher piezoelectric deformation coefficient "d". 33 The vibration direction of the second vibration unit 132 can be changed based on the crystal orientation. For example, when the crystal orientation of the second vibration unit 132 is the (001) crystal orientation, this can be the high voltage deformation coefficient "d". 33The vibration mode is "", and the vibrating member 100 can vibrate in the thickness direction (or vertical direction) (Z-axis vibration or vertical vibration), thereby causing an increase in the sound pressure level of the high-pitched vocal cords. For example, when the crystal direction of the second vibrating part 132 is the (011) crystal direction, this can be the high voltage deformation coefficient "d". 32 The vibration mode is "", and the vibrating member 100 can vibrate in the lateral direction (X-axis vibration, lateral vibration or horizontal vibration), thereby causing an increase in the sound pressure level of the low-pitched vocal cords.

[0145] According to embodiments of this disclosure, a first vibrating portion 131 that vibrates in the thickness direction (Z-axis vibration) and a second vibrating portion 132 that vibrates in the transverse direction (XY-axis vibration) can be provided, thereby improving the sound of the bass vocal cords. Furthermore, the second vibrating portion 132 having a (011) crystal orientation can be provided, thereby reducing the area occupied by the second vibrating portion 132 in the vibration device 130, thus improving the sound of the bass vocal cords and reducing the manufacturing cost of the vibration device 130 based on the second vibrating portion 132.

[0146] Reference Figure 3A The vibration device 130 according to embodiments of the present disclosure may include a second vibration part 132 adjacent to the first vibration part 131. The second vibration part 132 may include a second-first vibration part 132-1 and a second-second vibration part 132-2. The first vibration part 131 may be arranged at the center of the vibration member 100. The second vibration part 132 may be arranged above and below the first vibration part 131. The second vibration part 132 may be arranged above and below the first vibration part 131 relative to the first vibration part 131. For example, the second-first vibration part 132-1 may be arranged above the first vibration part 131. For example, the second-second vibration part 132-2 may be arranged below the first vibration part 131. For example, the second-first vibration part 132-1 may be a second vibration part, and the second-second vibration part 132-2 may be a third vibration part. It should be understood that the foregoing provides examples but does not limit the scope of the present disclosure. As used herein, references to the periphery of a first feature and a second feature can be used to indicate that the first feature is adjacent to the second feature, for example, by being arranged laterally adjacent in a direction parallel to the front surface of the vibrating member / display panel described herein. A second-first vibrating part 132-1 may be arranged adjacent to a first side of the first vibrating part 131, and a second-second vibrating part 132-2 may be arranged adjacent to a second side of the first vibrating part 131. The first side may be opposite to the second side.

[0147] The thickness of each of the first vibrating part 131 and the second vibrating part 132 can be from 0.1 mm to 0.3 mm, but the embodiments of this disclosure are not limited thereto. As the thickness of each of the first vibrating part 131 and the second vibrating part 132 gradually decreases, the voltage (or net electric field) applied per thickness can increase, and therefore, the vibration characteristics of each of the first vibrating part 131 and the second vibrating part 132 can be further enhanced. For example, when the thickness of the first vibrating part 131 is 0.1 mm, the thickness of the second vibrating part 132 is 0.2 mm, and 10 V is applied, the magnitude of the electric field applied per thickness can be 100 V / mm and 50 V / mm, respectively. Therefore, the magnitude of the electric field of each of the first vibrating part 131 and the second vibrating part 132 with a thickness of 0.1 mm can be increased by about two times or more, and the sound pressure level can be increased by about 6 dB, thereby further enhancing the vibration characteristics.

[0148] The second vibration section 132 can be arranged above and below the first vibration section 131 relative to the first vibration section 131, and therefore, lateral vibrations based on the second vibration section 132 can be induced. The second vibration section 132 may include a (011) crystal orientation, and therefore, when the second vibration section 132 is configured to be in d 32 When the length is greater in the direction (or width), the displacement can increase based on high aspect ratio vibration. For example, the second vibrating part 132 can be configured in a quadrilateral shape (e.g., a strip), but embodiments of this disclosure are not limited thereto. The aspect ratio can be in the width direction (d... 32 (direction) and thickness direction (d) 33 The ratio of direction (d) 32 / d 33 The second vibration section 132 can repeatedly contract and expand based on an external voltage, and when the XY axis length expands, the Z axis length can contract, i.e., vibration can be performed in opposite directions. Therefore, when the second vibration section 132 is a vibration section with a high aspect ratio (e.g., width / thickness direction), the X-axis length and / or Y-axis length can expand (or contract) relative to the Z-axis length in an aspect ratio manner, and thus, the vibration characteristics of the second vibration section 132 can be further enhanced. For example, when the width / thickness direction is 5, the vibration characteristics of the second vibration section 132 can be further enhanced by approximately five times.

[0149] Reference Figure 3CThe ratio "a' / b'" of the lateral length "a'" to the longitudinal length "b'" of the second vibrating part 132 (e.g., the second-1st vibrating part 132-1 and the second-2nd vibrating part 132-2) can be adjusted to 5 or greater, but embodiments of the present disclosure are not limited thereto. Therefore, the second vibrating part 132 can have a high vibration displacement, and thus, the vibration characteristics that cause the vibrating member 100 to vibrate can be increased, thereby outputting a high sound pressure level in the low-pitched vocal cords. For example, the lateral length of the second vibrating part 132 can be 5 cm to 10 cm, but embodiments of the present disclosure are not limited thereto.

[0150] Reference Figure 3B The first vibrating part 131 may have a quadrilateral shape, but the embodiments of this disclosure are not limited thereto. As another example, the first vibrating part 131 may be constructed as a square, rectangle, or rhombus. The longitudinal length "b" of the first vibrating part 131 may be adjusted to be longer than its transverse length "a". For example, the first vibrating part 131 may be along the thickness direction (d) 33 The vibration direction is increased, and therefore, the vibration characteristics can be enhanced when the area (or XY area) is increased. When the area of ​​the first vibrating part 131 is increased, the vibration characteristics can be enhanced, and therefore, the sound pressure level characteristics can be further enhanced.

[0151] According to embodiments of this disclosure, the second vibrating part 132 may be arranged above and below the first vibrating part 131 relative to the first vibrating part 131, and thus may supplement the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords, thereby providing a vibrating device 130 having sound characteristics and / or sound pressure level characteristics of the full-range pitch vocal cords including the low-pitched vocal cords. Furthermore, the first vibrating part 131 may be arranged at the center of the vibrating member 100 relative to the second vibrating part 132, thereby providing a vibrating device 130 for further enhancing the sound of the high-pitched vocal cords.

[0179] The vibration device 130 according to the embodiments of this disclosure can drive each of the first-1 vibration section 131-1, the first-2 vibration section 131-2, the first-3 vibration section 131-3, the first-4 vibration section 131-4, the second-1 vibration section 132-1, and the second-2 vibration section 132-2 individually, and therefore, the drive of each vibration section can be adjusted based on the desired sound (high-pitched vocal cords or low-pitched vocal cords). For example, in the case of achieving a high-pitched vocal cord sound, by increasing the voltage applied to the first vibration section 131 and decreasing the voltage applied to the second vibration section 132, the vibration device 130 can be implemented in the same vibration device 130 to emphasize (or enhance) the high-pitched vocal cords. As another example, in the case of achieving a low-pitched vocal cord sound, by decreasing the voltage applied to the first vibration section 131 and increasing the voltage applied to the second vibration section 132, the vibration device 130 can be implemented in the same vibration device 130 to emphasize (or enhance) the low-pitched vocal cords.

[0180] According to embodiments of this disclosure, the first vibrating part 131 can be arranged above and below the second vibrating part 132 relative to the second vibrating part 132, and thus can supplement the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords, thereby providing a vibration device 130 having sound characteristics and / or sound pressure level characteristics of the full-range pitch vocal cords including the low-pitched vocal cords. Furthermore, the area of ​​the first vibrating part 131 can be larger than the area of ​​the second vibrating part 132, thereby providing a vibration device 130 for further enhancing the sound of the high-pitched vocal cords.

For example, in the rear surface of the vibrating member 100 or the display panel, the first region A1 may be a left rear region, and the second region A2 may be a right rear region. With respect to the first direction X, the first region A1 and the second region A2 may be horizontally symmetrical with respect to the center line CL of the vibrating member 100 or the display panel, but embodiments of this disclosure are not limited thereto. For example, when the vibrating member 100 is a display panel, each of the first region A1 and the second region A2 may overlap with the display area of ​​the display panel.

[0224] According to another embodiment of this disclosure, the vibration device 130 may include a first vibration device 137 and a second vibration device 138, which are arranged on the rear surface of the vibration member 100 or the display panel. For example, the first vibration device 137 may be a first vibration generating device, a first displacement device, a first sound device, or a first sound generating device, but the terminology is not limited thereto. For example, the second vibration device 138 may be a second vibration generating device, a second displacement device, a second sound device, or a second sound generating device, but the terminology is not limited thereto.

[0225] The first vibration device 137 may be disposed in or at the first region A1 of the vibrating member 100 or the display panel. For example, the first vibration device 137 may be disposed at the central portion of the first region A1 of the vibrating member 100 or the display panel relative to the first direction X. As another example, the first vibration device 137 may be disposed relative to the first direction X near the central portion or edge (or periphery) of the first region A1 of the vibrating member 100 or the display panel. The first vibration device 137 according to embodiments of the present disclosure may cause the first region A1 of the vibrating member 100 or the display panel to vibrate, and thus may generate a first vibration sound or a first tactile feedback in the first region A1 of the vibrating member 100 or the display panel. For example, the first vibration device 137 according to embodiments of the present disclosure may directly cause the first region A1 of the vibrating member 100 or the display panel to vibrate, and thus may generate a first vibration sound or a first tactile feedback in the first region A1 of the vibrating member 100 or the display panel. For example, the first vibration sound may be a left-handed sound. According to embodiments of this disclosure, the size of the first vibration device 137, based on the characteristics of the first vibration sound or the desired sound characteristics of the device, may be half or less, or half or more, the size of the first region A1. In another embodiment of this disclosure, the size of the first vibration device 137 may be the size corresponding to the first region A1 of the vibration member 100 or the display panel. For example, the size of the first vibration device 137 may be less than or equal to the size of the first region A1 of the vibration member 100 or the display panel.

[0226] The second vibration device 138 may be arranged in or at the second region A2 of the vibrating member 100 or the display panel. For example, the second vibration device 138 may be arranged relative to the first direction X at the central portion of the second region A2 of the vibrating member 100 or the display panel. For example, the second vibration device 138 may be arranged relative to the first direction X near the central portion or edge (or periphery) of the second region A2 of the vibrating member 100 or the display panel. The second vibration device 138 according to embodiments of the present disclosure can cause the second region A2 of the vibrating member 100 or the display panel to vibrate, and thus can generate a second vibration sound or a second tactile feedback in the second region A2 of the vibrating member 100 or the display panel. For example, the second vibration device 138 according to embodiments of the present disclosure can directly cause the second region A2 of the vibrating member 100 or the display panel to vibrate, and thus can generate a second vibration sound or a second tactile feedback in the second region A2 of the vibrating member 100 or the display panel. For example, the second vibration sound may be a right-handed sound. According to embodiments of this disclosure, the size of the second vibration device 138, based on the characteristics of the second vibration sound or the desired sound characteristics of the device, may be half or less, or half or more, the size of the second region A2. In another embodiment of this disclosure, the size of the second vibration device 138 may be the size corresponding to the second region A2 of the vibration member 100 or the display panel. For example, the size of the second vibration device 138 may be less than or equal to the size of the second region A2 of the vibration member 100 or the display panel. Therefore, the first vibration device 137 and the second vibration device 138 may have the same size or different sizes based on the left and right sound characteristics and / or the overall sound characteristics of the device. Furthermore, the first vibration device 137 and the second vibration device 138 may be arranged in a symmetrical or asymmetrical configuration relative to the center line CL of the vibration member 100 or the display panel.

The second vibration device 138 may include one or more first vibration parts 131-12 and multiple second vibration parts 132-12 and 132-22. Figure 11 In the description, each of the first vibration device 137 and the second vibration device 138 is configured as follows: Figures 3A to 3C The embodiments of the vibration device 130 are described above, but the embodiments of this disclosure are not limited thereto. For example, each of the first vibration device 137 and the second vibration device 138 may include the above-described embodiments. Figures 4A to 4C , Figures 5A to 5C , Figures 6A to 6C , Figure 8A , Figure 8B as well as Figures 9A to 9C One of the vibration devices described.

[0229] For example, each of the first vibration device 137 and the second vibration device 138 may include the above reference. Figure 3A , Figure 4A , Figure 8A and Figure 9A At least one or more of the vibration devices 130 described herein. In such a configuration, each of the first vibration device 137 and the second vibration device 138 can achieve enhanced bass tone sound. For example, each of the first vibration device 137 and the second vibration device 138 may include the above-described vibration devices. Figure 5A , Figure 6A , Figure 9A and Figure 9C At least one or more of the vibration devices 130 described herein. In such a configuration, each of the first vibration device 137 and the second vibration device 138 can achieve a further enhanced high-pitched vocal cord sound.

[0230] According to embodiments of this disclosure, the connecting member 150 can be arranged between each of the first vibration device 137 and the second vibration device 138 and the rear surface of the vibration member 100 or the display panel. For example, each of the first vibration device 137 and the second vibration device 138 can be arranged at the rear surface of the vibration member 100 or the display panel via the connecting member 150. The connecting member 150 can be related to the above-mentioned... Figure 2 The described connecting member 150 is substantially the same, and therefore repeated descriptions of it can be omitted.

[0231] Therefore, the apparatus according to another embodiment of the present disclosure can output sound including left and right sounds in the forward direction of the vibrating member 100 or the display panel through the first vibration device 137 and the second vibration device 138 to provide sound to the user.

[0232] The vibration device 130 according to the embodiments of this disclosure may also include a plate 101.

[0233] According to embodiments of this disclosure, plate 101 can be connected to or coupled to the rear surface of vibrating member 100. For example, when vibrating member 100 is a light-emitting display panel that serves as a display panel, plate 101 can be disposed on the rear surface of the encapsulation portion of the light-emitting display panel. Plate 101 can be disposed on the rear surface of the encapsulation portion and can be configured as a bonding structure. Plate 101 can dissipate heat generated in the display panel. For example, plate 101 can be referred to as a heat dissipation member, heat sink, or heat radiator, but the terminology is not limited thereto.

[0234] According to embodiments of this disclosure, plate 101 can reinforce the mass of the vibrating device 130 arranged or suspended on the rear surface of the vibrating member 100. Therefore, plate 101 can reduce the resonant frequency of the vibrating device 130 due to the increased mass of the vibrating device 130. Consequently, plate 101 can enhance the sound characteristics and sound pressure level characteristics of the low-pitched vocal cords generated by the vibration of the vibrating device 130, and can improve the flatness of the sound characteristics. For example, the flatness of the sound characteristics can represent the amplitude deviation between the highest and lowest sound pressure levels. For example, plate 101 can be referred to as a weight member, mass member, or sound flattening member, but the terminology is not limited thereto.

[0235] Plate 101 may have the same shape and size as the vibrating member 100 or the display panel, or it may have the same shape and size as the vibrating device 130. In another embodiment of this disclosure, plate 101 may have a size different from that of the vibrating member 100 or the display panel. For example, the size of plate 101 may be smaller than (or less than) the size of the vibrating member 100 or the display panel. In another embodiment of this disclosure, plate 101 may have a size different from that of the vibrating device. For example, the size of plate 101 may be larger than or smaller than (or less than) the size of the vibrating device 130. The vibrating device 130 may have a size less than or equal to that of the vibrating member 100 or the display panel.

[0236] The plate 101 according to embodiments of this disclosure may include metallic materials. For example, the plate 101 may include one or more materials selected from stainless steel, Al, Mg, Mg alloy, magnesium-lithium (Mg-Li) alloy, and Al alloy, but embodiments of this disclosure are not limited thereto.

[0237] According to embodiments of this disclosure, the displacement (or bending force) or amplitude displacement (or vibration width) of the vibrating member 100 or display panel on which the plate 101 is arranged can decrease with increasing thickness of the plate 101 based on the stiffness of the plate 101. Therefore, the sound pressure level characteristics and low-pitched vocal characteristics of the sound generated based on the displacement (or vibration or drive) of the vibrating member 100 or display panel can be reduced.

[0238] According to embodiments of this disclosure, plate 101 can be coupled or connected to the rear surface of vibrating member 100 or display panel via a connecting member (or a fifth connecting member). The connecting member can be arranged between vibrating member 100 and plate 101.

[0239] The connecting member according to embodiments of this disclosure may include an adhesive layer having stronger adhesion or bonding force relative to each of the vibrating member 100 or the rear surface of the display panel and the vibrating device 130. For example, the connecting member may include a foam pad, double-sided tape, or adhesive. For example, the adhesive layer of the connecting member may include epoxy resin, acrylic resin, silicone resin, or urethane, but embodiments of this disclosure are not limited thereto. For example, the adhesive layer of the connecting member may be the same as or substantially the same as the adhesive layer of the connecting member 150, but embodiments of this disclosure are not limited thereto. For example, the adhesive layer of the connecting member may include an acryloyl-based material, which has stronger adhesion and higher hardness than urethane-based materials, enabling efficient transmission of vibrations from the vibrating device 130 to the vibrating member 100. In another embodiment of this disclosure, the adhesive layer of the connecting member may be configured to be different from the adhesive layer of the connecting member 150.

[0240] According to embodiments of this disclosure, the plate 101 can be integrated into or may be included in the vibration device 130. For example, the plate 101 and the vibration device 130 can be constructed as a single component (or device) or configured as an integral (or monolithic) structure. Therefore, when the plate 101 is arranged between the vibration device 130 and the vibration member 100 or the rear surface of the display panel, the assembly process between the vibration device 130 and the vibration member 100 or the display panel can be easily performed based on the component integration (or unification) between the plate 101 and the vibration device 130.

[0241] In another embodiment of this disclosure, when the plate 101 and the vibration device 130 are constructed as a single component (or device) or integrated into a single structure, the non-display panel can be configured as a vibrating plate. The plate 101 and the vibration device 130 can be arranged within or at the non-display panel. The plate 101 and the vibration device 130 can be connected or linked to each other via connecting members 150. For example, the plate 101 can be (or may include) one or more of the following materials: metal, wood, rubber, plastic, glass, fabric, fiber, paper, mirror, leather, interior materials of motor vehicles, ceilings of buildings, and interior materials of aircraft, but embodiments of this disclosure are not limited thereto. Therefore, the vibration device 130 can vibrate the non-display panel to output sound. In another embodiment of this disclosure, when the plate 101 and the vibration device 130 are constructed as a single component (or device) or integrated into a single structure, the plate 101 can be configured as a vibrating plate. For example, in the module (or structure) of plate 101 and vibration device 130, plate 101 may include one or more single non-metallic materials or composite non-metallic materials including wood, rubber, plastic, glass, fabric, fiber, paper, mirror and leather, but the embodiments of this disclosure are not limited thereto.

[0242] According to another embodiment of this disclosure, the plate 101 may include a plurality of openings. The plurality of openings may be configured to have a certain size and a certain spacing. For example, the plurality of openings may be arranged along a first direction X and a second direction Y to have a certain size and a certain spacing. Each of the plurality of openings can prevent sound waves (or sound pressure levels) based on the vibration of the vibrating device 130 from being dispersed by the plate 101, and can allow the sound waves to be concentrated on the vibrating member 100, and thus can minimize the vibration loss caused by the plate 101, thereby increasing the sound pressure level characteristics of the sound generated based on the vibration of the vibrating member 100. For example, the plate 101 including the plurality of openings may have a grid shape. For example, the plate 101 including the plurality of openings may have a mesh plate.

[0243] An apparatus according to an embodiment of the present disclosure may include two or more vibration devices 137 and 138, and therefore, a sound including a left sound and a right sound may be provided to a user based on the vibration of the two or more vibration devices 137 and 138.

[0244] Furthermore, the apparatus according to embodiments of this disclosure may also include a plate 101 disposed on the rear surface of the vibrating device 130, and thus, the resonant frequency of the vibrating device 130 may be reduced. Therefore, the sound characteristics and sound pressure level characteristics of the bass vocal cords generated based on the vibration of the vibrating member 100 or the display panel according to embodiments of this disclosure may be increased based on the vibration of the vibrating device 130, and the flatness of the sound characteristics may be enhanced.

[0245] Furthermore, in the apparatus according to embodiments of the present disclosure, each of two or more vibration devices 137 and 138 may be configured with or as a first vibration part and a second vibration part, and thus, an apparatus may be provided in which the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords are further enhanced.

[0246] Figure 12 An apparatus according to another embodiment of the present disclosure is shown.

[0247] Reference Figure 12 In another embodiment of the apparatus according to the present disclosure, the vibration device 130 may include one or more first vibration parts 131 and a plurality of second vibration parts 132. For example, one or more first vibration parts 131 may include first-1 vibration part 131-1, first-2 vibration part 131-3, first-3 vibration part 131-3, first-4 vibration part 131-4, first-5 vibration part 131-5, first-6 vibration part 131-6, first-7 vibration part 131-7 and first-8 vibration part 131-8, and the plurality of second vibration parts 132 may include second-1 vibration part 132-1, second-2 vibration part 132-2, second-3 vibration part 132-3 and second-4 vibration part 132-4.

[0248] A drive signal (or sound signal) can be provided to each of the 1-1 to 1-8 vibrating parts 131-1 to 131-8 to output sound. In embodiments of this disclosure, an example of active sound drive will be described below. For example, in a television screen, an example will be described where subtitles such as news are displayed on the left side of the screen and a news anchor narrating the news is displayed on the right side of the screen.

[0249] For example, a first drive signal DS1 can be applied to the first-1 vibrating section 131-1, and a second drive signal DS2 can be applied to the first-2 vibrating section 131-2. Because the left side of the screen displays subtitles such as news text, the drive can be performed to reduce the characteristics of the high-pitched vocal cords. For example, a ninth drive signal DS9 can be applied to the second-1 vibrating section 132-1, and a tenth drive signal DS10 can be applied to the second-2 vibrating section 132-2. Because the left side of the screen displays subtitles such as news text, the drive can be performed to reduce the characteristics of the high-pitched vocal cords. A fifth drive signal DS5 can be applied to the first-5 vibrating section 131-5, and a sixth drive signal DS6 can be applied to the first-6 vibrating section 131-6. Because the left side of the screen displays subtitles such as news text, the drive can be performed to reduce the characteristics of the high-pitched vocal cords.

[0250] For example, a third drive signal DS3 can be applied to the first-third vibrating section 131-3, and a fourth drive signal DS4 can be applied to the first-fourth vibrating section 131-4. Since the right side of the screen displays a news anchor, this drive can be applied to enhance the characteristics of the high-pitched vocal cords. An eleventh drive signal DS11 can be applied to the second-third vibrating section 132-3, and a twelfth drive signal DS12 can be applied to the second-fourth vibrating section 1332-4. Since the right side of the screen displays a news anchor, this drive can be applied to enhance the characteristics of the high-pitched vocal cords. A seventh drive signal DS7 can be applied to the first-seventh vibrating section 131-7, and an eighth drive signal DS8 can be applied to the first-eighth vibrating section 131-8. Since the right side of the screen displays a news anchor, this drive can be applied to enhance the characteristics of the high-pitched vocal cords.

[0251] According to embodiments of this disclosure, by applying separate or independent drive signals (or sound signals) to the first and second vibration portions, drive signals based on desired sound characteristics can be applied, and thus, an apparatus having desired sound characteristics can be realized.

Sound can be measured with the microphone perpendicular to the vibration device. The sound collected by the microphone can be input to the control PC via the sound card, and the control program can examine the input sound to analyze the sound of the vibration device. For example, the frequency response characteristics in the frequency range of 20 Hz to 20 kHz can be measured using a pulse program. Measurements can be performed by applying 1 / 3 octave band smoothing in a sine sweep within the range of 0.15 kHz to 20 kHz.

Furthermore, the SPL from 10 kHz to 20 kHz is approximately 65.4 dB, and the SPL from 0.2 kHz to 20 kHz is approximately 54.9 dB.

[0340] Figure 20 The sound output characteristics of a device according to another embodiment of the present disclosure are shown.

[0341] The measurement methods for sound output characteristics can be found in the above reference. Figure 19 The descriptions provided are the same or substantially the same, and therefore their descriptions can be omitted.

[0342] Figure 20 This refers to the sound output characteristics of a multi-crystal crystal. (Refer to...) Figure 20 It can be seen that the sound pressure level (SPL) from 0.2 kHz to 1 kHz is approximately 63.3 dB, and the SPL from 1 kHz to 10 kHz is approximately 69.5 dB. Furthermore, it can be seen that the SPL from 10 kHz to 20 kHz is approximately 80.3 dB, and the SPL from 0.2 kHz to 20 kHz is approximately 67.5 dB. This is consistent with the characteristics of a single crystal. Figure 19 In comparison, the sound pressure level characteristics can be seen to be increased (or higher).

[0343] Figure 21 The sound output characteristics of a device according to another embodiment of the present disclosure are shown.

[0344] The measurement methods for sound output characteristics can be found in the above reference. Figure 19 The descriptions provided are the same or substantially the same, and therefore their descriptions can be omitted.

[0345] exist Figure 21 In the middle, solid lines represent Figures 3A to 3C The sound output characteristics of the vibrating device are shown, and the dashed line represents the sound output characteristics of the polycrystalline material.

[0346] Reference Figure 21 In the solid lines, it can be seen that the sound pressure level (SPL) from 0.2 kHz to 1 kHz is approximately 67.5 dB, and the SPL from 1 kHz to 10 kHz is approximately 73.9 dB. Furthermore, it can be seen that the SPL from 10 kHz to 20 kHz is approximately 80.7 dB, and the SPL from 0.2 kHz to 20 kHz is approximately 74.2 dB. In the dashed lines, as shown above... Figure 20As described, it can be seen that the sound pressure level (SPL) at frequencies from 0.2 kHz to 1 kHz is approximately 63.3 dB, and the SPL at frequencies from 1 kHz to 10 kHz is approximately 69.5 dB. Furthermore, it can be seen that the SPL at frequencies from 10 kHz to 20 kHz is approximately 80.3 dB, and the SPL at frequencies from 0.2 kHz to 20 kHz is approximately 67.5 dB. Therefore, compared to a polycrystalline crystal, when a single-crystal and polycrystalline crystal are provided according to embodiments of this disclosure, it can be seen that the average SPL increases by approximately 7 dB or more. Furthermore, it can be seen that the SPL of each of the low-pitched and mid-pitched vocal bands increases without loss of the SPL at frequencies of 8 kHz or higher, which are considered high-pitched vocal bands. The low-pitched vocal band may be 500 Hz or lower and the mid-pitched vocal band may be 500 Hz to 8 kHz, but embodiments of this disclosure are not limited thereto.

[0347] Figure 22 The sound output characteristics of another device according to an embodiment of this disclosure are shown.

[0348] The measurement methods for sound output characteristics can be found in the above reference. Figure 19 The descriptions provided are the same or substantially the same, and therefore the descriptions of them may be omitted.

[0350] Reference Figure 22 In the solid lines, it can be seen that the sound pressure level (SPL) from 0.2 kHz to 1 kHz is approximately 75.2 dB, and the SPL from 1 kHz to 10 kHz is approximately 77.5 dB. Furthermore, it can be seen that the SPL from 10 kHz to 20 kHz is approximately 84.6 dB, and the SPL from 0.2 kHz to 20 kHz is approximately 77.9 dB. In the dashed lines, as shown above... Figure 20As described, it can be seen that the sound pressure level at frequencies from 0.2 kHz to 1 kHz is approximately 72.6 dB, and the sound pressure level at frequencies from 1 kHz to 10 kHz is approximately 72.3 dB. Furthermore, it can be seen that the sound pressure level at frequencies from 10 kHz to 20 kHz is approximately 92.1 dB, and the sound pressure level at frequencies from 0.2 kHz to 20 kHz is approximately 72.4 dB. Therefore, it can be seen that as the size (or area) of the first vibrating part 131, including the polycrystalline material, increases, the average sound pressure level increases by approximately 6 dB or more. According to embodiments of this disclosure, because the first vibrating part 131 vibrates in the vertical direction (d33 direction), the vibration characteristics can be enhanced with increasing area. The vibration characteristics can be enhanced with increasing area of ​​the first vibrating part 131, and therefore, it can be seen that the sound pressure level characteristics are further enhanced.

[0352] The measurement methods for sound output characteristics can be found in the above reference. Figure 19 The descriptions provided are the same or substantially the same, and therefore their descriptions can be omitted.

For example, Figure 23 It shows about Figure 5A and Figure 6A The sound output characteristics of the interval between the second vibrating parts 132-1 and 132-2. Figure 23In the diagram, dashed lines represent a spacing of 0 cm between single crystals, dotted lines represent a spacing of 4 cm, and solid lines represent a spacing of 8 cm. Within the dashed lines, it can be seen that the sound pressure level (SPL) is approximately 46.8 dB from 0.2 kHz to 1 kHz, and approximately 58.0 dB from 1 kHz to 10 kHz. Furthermore, it can be seen that the SPL is approximately 68.5 dB from 10 kHz to 20 kHz, and approximately 55.6 dB from 0.2 kHz to 20 kHz. Additionally, within the dotted lines, it can be seen that the SPL is approximately 55.3 dB from 0.2 kHz to 1 kHz, and approximately 61.3 dB from 1 kHz to 10 kHz. Moreover, it can be seen that the SPL is approximately 66.7 dB from 10 kHz to 20 kHz, and approximately 60.0 dB from 0.2 kHz to 20 kHz. Furthermore, in the solid lines, it can be seen that the sound pressure level (SPL) from 0.2 kHz to 1 kHz is approximately 47.5 dB, and the SPL from 1 kHz to 10 kHz is approximately 57.9 dB. Additionally, it can be seen that the SPL from 10 kHz to 20 kHz is approximately 65.3 dB, and the SPL from 0.2 kHz to 20 kHz is approximately 55.4 dB.

[0354] According to embodiments of this disclosure, a single crystal having a (011) crystal orientation can be d 32 Vibrational modes (or XY-axis vibrations) are observed, and therefore, the aspect ratio can affect the vibrational characteristics. A single crystal with a (011) crystal orientation can have d... 33 Vibration mode (or Z-axis vibration), and therefore, when the device is configured such that the aspect ratio and vibration interference of the single crystal phase are small, the d32 vibration mode (or XY-axis vibration) can be a highly efficient vibration mode, thereby enhancing the sound pressure level of the low-pitched vocal cords.

[0355] When the spacing between single crystals with a (011) crystal orientation is 0 cm, the device can be driven based on a single crystal, and therefore, the aspect ratio can be reduced. Therefore, d 33 Vibration modes (or Z-axis vibrations) can be highly efficient, and thus it can be seen that the sound pressure level of the high-pitched vocal cords (e.g., 10 kHz to 20 kHz) is enhanced, but the sound pressure level of the low-pitched vocal cords (e.g., 0.2 kHz to 1 kHz) is reduced.

[0356] When the spacing between single crystals with a (011) crystal orientation is 4 cm, without interfering with the d of each single crystal... 33 In the case of vibration mode (or Z-axis vibration), d can be strengthened. 32Vibration modes (or XY axis vibrations), and thus it can be seen that the sound pressure level of the low-pitched vocal cords (e.g., 0.2 kHz to 1 kHz) increases and the sound pressure level of the mid-pitched vocal cords (e.g., 1 kHz to 10 kHz) increases.

[0357] When the spacing between single crystals with (011) crystal orientation is 8 cm, the d-strength of each single crystal can be reduced. 32 The effect of vibration mode (or XY axis vibration) is thus observed, and therefore, it can be seen that the sound pressure level of the low-pitched vocal cords and the high-pitched vocal cords decreases.
