[0002] This application claims priority to Korean Patent Application No. 10-2023-0078508, filed in Korea on June 19, 2023, the entire contents of which are expressly incorporated herein by reference. Technical Field

[0003] This disclosure relates to sound devices and vehicle equipment that includes sound devices. Background Art

[0004] The vehicle includes a sound device that outputs sound based on audio signals output from a multimedia device, and such a sound device may include an automotive audio system. For example, a sound device used in a vehicle may include front speakers and rear speakers configured as coil-type devices. Summary of the Invention

[0005] However, the audio equipment in a vehicle may be limited by the coil-type design when outputting realistic sound or multi-channel stereo through the front and rear speakers. Furthermore, while increasing the number of speakers in a vehicle's audio equipment can produce stereo sound, the increase in the number of speakers is limited by the size of the coil-type speakers and the space constraints within the vehicle, making it impossible to provide realistic sound or stereo using compact and aesthetically pleasing coil-type designs.

[0006] The inventors of this disclosure have recognized the problems and shortcomings of the related art and have conducted extensive research and experiments on enhancing the sound characteristics and / or sound pressure level characteristics of sound devices for vehicles. Based on this extensive research and experimentation, the inventors have invented a sound device that can enhance sound characteristics and / or sound pressure level characteristics, and a vehicle device including the sound device.

[0007] One or more aspects of this disclosure are intended to provide sound devices that can enhance sound characteristics and / or sound pressure level characteristics, and vehicle equipment including such sound devices.

[0008] Further features, advantages, and aspects will be set forth in the description which follows, and will in part become apparent from the description, or may be learned by practice of the inventive concept provided herein.

[0079] 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 / or convenience, the dimensions, lengths, and thicknesses of layers, regions, and elements, and their descriptions, may be exaggerated. DETAILED DESCRIPTION

[0080] Reference will now be made to various aspects of this disclosure, examples of which may be illustrated in the accompanying drawings. In the following description, detailed descriptions of well-known methods, functions, structures, or configurations may be omitted for brevity where such descriptions might unnecessarily obscure aspects of this disclosure. Furthermore, repeated descriptions may be omitted for brevity. The described processing steps and / or the progression of operations are non-limiting examples.

[0081] The order of steps and / or operations is not limited to the order set forth herein and may be changed to occur in a different order than that described herein, except for steps and / or operations that must occur in a specific order. In one or more examples, two consecutive operations may be performed substantially simultaneously, or, depending on the functions or operations involved, they may be performed in reverse or a different order.

[0082] Unless otherwise stated, even if the same reference numerals are shown in different figures, they may refer to the same elements throughout. Unless otherwise stated, the same reference numerals may be used to refer to the same or substantially the same elements throughout the specification and figures. In one or more aspects, unless otherwise stated, the same elements (or elements with the same name) in different figures may have the same or substantially the same function and properties. The names of the various elements used in the following description are chosen for convenience only and may therefore differ from the names used in actual products.

[0083] The advantages and features of this disclosure, and its implementation methods, have been illustrated by referring to the various aspects described in the accompanying drawings. However, this disclosure may be embodied in different forms and should not be construed as limited to the exemplary aspects set forth herein. Rather, these exemplary aspects are examples and are provided to make this disclosure thorough and complete in order to assist those skilled in the art in understanding the inventive concept, without limiting the scope of protection of this disclosure.

[0084] The shapes, dimensions (e.g., size, length, width, height, thickness, position, radius, diameter, and area), proportions, ratios, angles, numbers, number of elements, etc., disclosed herein, including those shown in the accompanying drawings, are merely examples, and therefore, this disclosure is not limited to the details shown. However, it should be noted that the relative dimensions of the components shown in the accompanying drawings are part of this disclosure.

[0085] When terms such as “comprising,” “having,” “including,” “containing,” “constituting,” “made of,” “formed by,” “composed of,” etc., are used relative to one or more elements (e.g., layer, membrane, region, component, segment, member, part, area, zone, section, step, operation, etc.), one or more other elements may be added unless terms such as “only” are used. The terminology used in this disclosure is for describing particular exemplary aspects only and is not intended to limit the scope of this disclosure. Unless the context clearly indicates otherwise, singular terms may include plural forms.

[0086] Unless otherwise stated, the word "exemplary" is used to mean used as an example or illustration. An implementation is an exemplary implementation, and an aspect is an exemplary aspect. In one or more implementations, "implementation," "aspect," "example," etc., should not be construed as superior or preferred to other implementations. Unless otherwise stated, aspect, example, exemplary aspect, etc., may refer to one or more aspects, one or more examples, one or more exemplary aspects, etc. Furthermore, the term "may" encompasses all the meanings of the term "able to."

[0087] In one or more respects, unless otherwise expressly stated, components, features, or related information (e.g., levels, ranges, dimensions, sizes, etc.) are interpreted as including a range of errors or tolerances, even if no explicit description of such a range of errors or tolerances is provided. An error or tolerance range can be caused by a variety of factors (e.g., process factors, internal or external influences, noise, etc.). When interpreting numerical values, unless otherwise expressly stated, the value is interpreted as including the range of errors.

[0088] When describing positional relationships, such as using terms like "on," "above," "top," "above," "below," "above," "below," "beneath," "near," "adjacent," "next to," "near," "on the side," "near," "on the side of," or "on top," to describe the positional relationship between two components (e.g., layers, membranes, regions, parts, sections, etc.), one or more other components may be located between the two components unless more restrictive terms such as "closely adjacent," "directly," or "nearly" are used. For example, when a structure is described relative to another structure as follows: When the terms "on," "above," "on top," "above," "below," "above," "below," "beneath," "near," "close to," "adjacent to," "beside," "near," "on the side of," "on the side of," or "above" are used, the description should be interpreted to include situations where 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," "back," "left," "right," "top," "bottom," "down," "up," "upper part," "lower part," "above," "below," "column," "row," "vertical," and "horizontal" refer to any frame of reference.

[0089] Spatial relative terms such as “below,” “under,” “lower,” “above,” “upper,” “superior,” and “superior” can be used to describe the relationships between various elements (e.g., layers, films, regions, components, segments, etc.) as shown in the figures. Spatial relative terms should be understood to include terms describing different orientations of elements in use or operation, in addition to those depicted in the figures. For example, if the elements shown in the figures are flipped, an element described as “below” or “under” other elements would be oriented as “above” other elements. Therefore, the term “below” (which is an example term) can include all directions of “above” and “below.” Similarly, the exemplary terms “above” or “superior” can include both directions of “above” and “below.”

[0090] When describing temporal relationships, when the temporal sequence is described as such as “after,” “following,” “next,” “before,” “previously,” “in front of,” etc., it may include discontinuous or non-sequential situations, and therefore one or more other events may occur in between, unless more restrictive terms such as “just,” “immediately,” or “directly” are used.

[0091] Terms such as “below,” “lower,” “above,” and “upper” may be used herein to describe the relationships between the elements shown in the accompanying drawings. It should be understood that these terms are spatially relative and based on the orientation depicted in the drawings.

[0092] It should be understood that although the terms "first," "second," etc., may be used herein to describe various elements (e.g., layer, membrane, region, component, segment, member, part, area, zone, section, step, operation, etc.), these elements should not be limited by these terms, for example, not by any particular order, priority, or number of elements. These terms are used only to distinguish one element from another. For example, without departing from the scope of this disclosure, a first element may refer to a second element, and similarly, a second element may refer to a first element. Furthermore, without departing from the scope of this disclosure, first elements, second elements, etc., may be named arbitrarily as is convenient for those skilled in the art. For clarity, the function or structure of these elements (e.g., first element, second element, etc.) is not limited by the ordinal number or name preceding the element. Furthermore, a first element may include one or more first elements. Similarly, a second element, etc., may include one or more second elements, etc.

[0093] In describing elements of this disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to identify the corresponding element from other elements, and are not used to define the nature, basis, sequence, order, or number of elements.

[0094] When an element (e.g., layer, film, region, component, segment, etc.) is described as “connected,” “coupled,” “attached,” “adheded,” etc. to another element, unless otherwise stated, the element may be directly connected, coupled, attached, adhered, etc. to another element, or indirectly connected, coupled, attached, adhered, etc. to another element by setting or inserting one or more intervening elements between the elements.

[0095] Unless otherwise stated, the description of a component (e.g., layer, film, region, component, segment, etc.) as "contacting" or "overlapping" with another component means that the component can not only directly contact or overlap with another component, but also indirectly contact or overlap with another component by setting or inserting one or more intervening components between the components.

[0096] Phrases such as "providing," "setting," "connecting," or "coupling" an element (e.g., layer, film, region, component, segment, etc.) in, on, or with or to another element can be understood as, for example, that at least a part of the element is in, on, or with at least a part of the other element, or is provided, set, connected, or coupled to at least a part of the other element, or the entire element is in, on, or with or to another element. Phrases such as "contacting" or "overlapping" an element (e.g., layer, film, region, component, segment, etc.) with another element can be understood, for example, as that at least a part of the element contacts or overlaps with at least a part of the other element, the entire element contacts or overlaps with at least a part of the other element, or at least a part of the element contacts or overlaps with the entirety of the other element.

[0097] Terms such as “row” or “direction” should not be interpreted solely based on the geometric relationship that the corresponding rows or directions are parallel or perpendicular to each other. Such terms can refer to a wider range of lines or directions within which the components of this disclosure can be functionally operated. For example, terms such as “first direction,” “second direction,” etc., directions parallel or perpendicular to the “x-axis,” “y-axis,” or “z-axis,” should not be interpreted solely based on the geometric relationship that the corresponding directions are parallel or perpendicular to each other, but can refer to directions with a broader directional scope within the range within which the components of this disclosure can be functionally operated.

[0098] 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, each of the phrases “at least one of the first, second, or third items” and “at least one of the first, second, and third items” can mean: (i) a combination of items provided by one or more of the first, second, and third items; or (ii) only one of the first, second, and third items.

[0099] The expressions "first element," "second element," and " / or" "third element" should be understood to cover one of the first, second, and third elements, as well as any and all combinations of the first, second, and third elements. As an example, A, B, and / or C cover only A; only B; only C; any one of A, B, and C (e.g., A, B, or C); some combinations of A, B, and C (e.g., A and B; A and C; or B and C); and all of A, B, and C. Furthermore, the expression "A / B" can be understood as A and / or B. For example, the expression "A / B" could refer to only A; only B; A or B; or A and B.

[0100] In one or more aspects, unless otherwise stated, for convenience, the terms "between" and "among which" 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. Furthermore, when an element (e.g., layer, membrane, region, component, segment, etc.) is referred to as being "between" at least two elements, the element may be the only element among at least two elements, or there may be one or more intervening elements.

[0101] 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 foregoing expression may be two. In one or more examples, the number of elements involved in the foregoing expression may be more than two.

[0102] In one or more respects, unless otherwise stated, for convenience, the phrases “one or more of them” and “one or more of them” may be used interchangeably.

[0103] The term "or" means "inclusive or" rather than "exclusive or". For example, unless otherwise stated or clear from the context, the expression "x uses a or b" means any of the natural inclusive permutations. For example, "a or b" can mean "a", "b", or "a and b". For example, "a, b, or c" can mean "a", "b", "c", "a and b", "b and c", "a and c", or "a, b, and c".

[0104] The features of various aspects of this disclosure may be coupled or combined with each other, may be technically related to each other, and may operate, link, or drive together in various ways. The aspects of this disclosure may be implemented or performed independently of each other, or may be implemented or performed together in a common dependency or relation. In one or more aspects, components of each device according to various aspects of this disclosure may be operatively coupled and configured.

[0105] Unless otherwise specified, the terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the examples pertain. It should also be understood that terms (e.g., those defined in common dictionaries) shall be interpreted as having a meaning consistent with, for example, their meaning in the relevant technical context, and shall not be interpreted as having an idealized or overly formal meaning, unless otherwise expressly specified herein.

[0106] The terms used herein have been selected as those commonly used in the relevant technical fields; however, other terms may exist depending on technological development and / or changes, conventions, preferences of those skilled in the art, etc. Therefore, the terms used herein should not be construed as limiting technical concepts, but rather as examples of terms used to describe exemplary aspects.

[0107] Furthermore, in certain circumstances, the terminology may be arbitrarily chosen by the applicant, and in such cases, its detailed meaning is described herein. Therefore, the terminology used herein should be understood not only based on its name but also on its meaning and content.

[0108] The “X-axis direction,” “Y-axis direction,” and “Z-axis direction” should not be interpreted solely by their geometric relationship of being perpendicular to each other, but can have a broader directionality within the scope of the elements of this disclosure that can function.

[0109] In the following description, various exemplary aspects of this disclosure are described in detail with reference to the accompanying drawings. Reference numerals for each element in the drawings may indicate the same element in other drawings, and unless otherwise stated, the same reference numerals may refer to the same element. Identical or similar elements may be indicated by the same reference numerals, even if they are depicted in different drawings.

[0110] In addition, for ease of description, the scale, dimensions, size and thickness of each of the elements shown in the accompanying drawings may differ from the actual scale, dimensions, size and thickness, and therefore, aspects of this disclosure are not limited to the scale, dimensions, size and thickness shown in the accompanying drawings.

For example, the vehicle interior material 130 or the base component 131 may be configured to cover one or more of the main structure 110 and the external material 120 in the interior space IS of the vehicle 10. For example, the vehicle interior material 130 or the base component 131 may be configured to cover a surface (or inner surface) of at least one or more of the main frame, side frame, door frame, and handle frame exposed in the interior space IS of the vehicle 10.

[0138] The base member 131 may include at least one or more flat portions and curved portions.

[0139] An external member 133 may be disposed on a base member 131. For example, the external member 133 may be configured to cover the base member 131. The external member 133 may cover the base member 131 at an interior portion or interior space IS of the vehicle 10, and may be configured to be exposed at an interior portion or interior space IS of the vehicle 10. For example, the external member 133 may be disposed on or coupled to a front surface (or interior surface) of the base member 131 exposed at an interior space IS of the vehicle 10.

[0140] The vehicle interior material 130 or exterior component 133 according to embodiments of this disclosure may include any one or more materials such as plastic, glass, fiber, leather, cloth, rubber, mirror, wood, paper, carbon, and metal, but embodiments of this disclosure are not limited thereto.

[0144] According to another embodiment of this disclosure, the sound device 30 can be configured to be surrounded by a housing. A space can be provided between the sound device 30 and the housing, and sound (or sound pressure level) can be output based on the vibration of the air between the sound device 30 and the housing based on the vehicle interior material 130. However, there may be a problem that the sound of the low-pitched vocal bands is not output, and there may be a problem that the flatness of the sound pressure level is reduced because the number of peaks and drops in the reproduction frequency band of the sound (or sound pressure level) generated based on the vibration of the vehicle interior material 130 increases, and each of the highest and lowest sound pressure levels in the reproduction frequency band of the sound (or sound pressure level) generated based on the vibration of the vehicle interior material 130 increases. Peaks can be the phenomenon of sound pressure levels bouncing at a specific frequency, while drops can be the phenomenon of generating low sound pressure levels as the occurrence of sound with a specific frequency decreases. The flatness of the sound characteristics can be the level of deviation between the highest and lowest sound pressure levels.

[0145] The inventors of this disclosure have conducted extensive research and experimentation on realizing a sound device and a vehicle device including the sound device, wherein the sound characteristics of the low-pitched vocal cords can be improved and the flatness characteristics of the sound pressure level can be enhanced.

The second housing 312 may support the second surface of the sound generation module 330, with an internal space 313 between them. The second housing 312 may be configured to surround the second surface of the sound generation module 330. The second housing 312 may be configured to cover the second surface of the sound generation module 330.

[0172] According to embodiments of this disclosure, the second housing 312 can be configured to have a shape opposite to that of the first housing 311. For example, the first housing 311 and the second housing 312 can be configured to have symmetrical shapes or symmetrical structures, with a sound generation module 330 located between them.

[0173] Each of the first vibration device 333 and the second vibration device 335 can cause the vibrating member 331 to vibrate to generate sound (or sound pressure level or sound wave) in the internal space 313 of the housing 310. The housing 310 can vibrate based on the sound (or sound pressure level or sound wave) in the internal space 313 of the housing 310, and the vehicle interior material 130 can vibrate based on the vibration of the housing 310 to generate (or output) sound. For example, the vehicle interior material 130 can vibrate based on the sound (or sound pressure level or sound wave) generated in the internal space 313 of the housing 310 through the vibration of the first housing 311 to generate (or output) sound.

[0174] According to embodiments of the present disclosure, the internal space 313 of the housing 310 may include a first space 313a and a second space 313b.

[0175] The vibration member 331 can be disposed in the internal space 313 of the housing 310. The vibration member 331 can be disposed in the internal space 313 of the housing 310 and can be connected to a vibration device. For example, the vibration member 331 can be disposed in the internal space 313 of the housing 310 and can be connected to one or more of the first vibration device 333 and the second vibration device 335. The vibration member 331 can be disposed between the first vibration device 333 and the second vibration device 335.

[0176] The vibrating member 331 can be disposed or configured in the region between the first housing 311 and the second housing 312 of the housing 310. The vibrating member 331 can be configured to divide the internal space 313 of the housing 310 into a first space 313a and a second space 313b. For example, the internal space 313 of the housing 310 can be divided into a first space 313a and a second space 313b by the vibrating member 331. For example, the first space 313a of the internal space 313 can be disposed in the region between the first housing 311 and the vibrating member 331 of the housing 310, and can be covered by the vibrating member 331. The second space 313b of the internal space 313 can be disposed in the region between the second housing 312 and the vibrating member 331 of the housing 310, and can be covered by the vibrating member 331.

[0177] According to embodiments of this disclosure, the first vibration device 333 and the second vibration device 335 may be located in different spaces within the internal space 313 of the housing 310. For example, the first vibration device 333 may be located in the first space 313a. For example, the second vibration device 335 may be located in the second space 313b.

[0178] The first space 313a can be between the sound generating module 330 and the first housing 311. For example, the first space 313a can be between the first surface of the sound generating module 330 and the first housing 311. The first space 313a can also be between the first vibration device 333 and the first housing 311. The second space 313b can be between the sound generating module 330 and the second housing 312. For example, the second space 313b can be between the second surface of the sound generating module 330, which is different from (or opposite to) the first surface, and the second housing 312. The second space 313b can also be between the second vibration device 335 and the second housing 312. For example, the internal space 313 can be a gap space, an air space, a vibration space, a sound space, a sound box, or a sealed space, etc., but the embodiments of this disclosure are not limited to these.

[0179] The sound generation module 330 can generate a sound pressure level (or sound or sound wave) in the internal space 313 of the housing 310 to cause the housing 310 to vibrate, and can cause the vehicle interior material 130 to vibrate based on the vibration of the housing 310. For example, the sound generation module 330 can be configured to vibrate a first housing 311 of the housing 310 to cause the vehicle interior material 130 to vibrate. For example, the sound generation module 330 can generate a sound pressure level (or sound or sound wave) in the internal space 313 of the housing 310 to cause the first housing 311 to vibrate, and can cause the vehicle interior material 130 to vibrate based on the vibration of the first housing 311.

[0180] According to embodiments of the present disclosure, the first housing 311 may include an opening 310o.

[0181] The opening 310o can be configured to pass through (or vertically pass through) the first housing 311 along the thickness direction Z (or vertical direction) of the housing 310. The opening 310o can be connected to (or communicate with) the internal space 313. For example, the opening 310o can be connected to (or communicate with) the first space 313a. For example, the opening 310o can be configured to reduce the air pressure in the internal space 313 of the housing 310. For example, the opening 310o can be configured to reduce the air pressure in the first space 313a. The opening 310o can be configured to reduce the air pressure in the first space 313a of the first housing 311 or the air pressure in the first space 313a located between the vibrating member 331 and the first housing 311. Therefore, the frequency band of the bass band can be extended, and thus the sound characteristics of the bass band can be improved. Because the pressure (or air pressure) in the first space 313a is reduced by the opening 310o, the displacement (or bending force) of the first vibrating device 333 disposed between the vibrating member 331 and the first housing 311 can be increased, and therefore, the frequency band of the bass vocal band can be extended, thereby enhancing the sound characteristics and / or sound pressure level characteristics of the bass vocal band. Therefore, the sound characteristics (or sound pressure level) of the bass vocal band generated based on the vibration of the first vibrating device 333 and / or the second vibrating device 335 can be improved.

[0182] According to embodiments of this disclosure, the opening 310o may be configured to correspond to the central portion of the sound generation module 330. For example, the opening 310o may be configured to correspond to the vibration devices 333 and 335. For example, the opening 310o may be configured to correspond to the central portion of the first vibration device 333 and the second vibration device 335. For example, the opening 310o may be configured to correspond to the central portion of each of the first vibration device 333 and the second vibration device 335. For example, the internal space 313 of the housing 310 may include a space connected to the opening 310o. For example, the internal space 313 of the housing 310 may include a first space 313a connected to the opening 310o.

[0183] According to embodiments of the present disclosure, the opening 310o may have a size smaller than that of the first vibration device 333. For example, the opening 310o may have a size smaller than that of the first vibration device 333 disposed at the vibration member 331. For example, the opening 310o may include a linear shape having a size (or length) smaller than that of the first vibration device 333 disposed at the vibration member 331. For example, the opening 310o may be a hole, a slot, or a slit, but embodiments of the present disclosure are not limited thereto. For example, the opening 310o may be a sound emitting portion, a first sound emitting port, a sound output portion, a sound output port, a sound output hole, or a vent hole, but embodiments of the present disclosure are not limited thereto.

[0184] The opening 310o can be the space through which sound waves generated by the vibration of the sound generation module 330 propagate (or are transmitted) to the interior space IS of the vehicle 10. For example, the vibration of the sound generation module 330 can be transmitted to the interior space IS of the vehicle 10 through the opening 310o. For example, sound waves (or sounds) based on the vibration of the sound generation module 330 can be transmitted (or output or emitted) to the interior space IS of the vehicle 10 through the opening 310o. Therefore, the vibration width (or displacement width) of the vibrating member 331 based on the vibration of the sound generation module 330 can be increased, and thus, the sound characteristics and / or sound pressure level characteristics generated based on the vibration of the vibrating member 331 can be enhanced.

[0185] The first housing 311, including the opening 310o, can be positioned closer to the vehicle interior material 130 than the second housing 312. For example, the first housing 311, including the opening 310o, can be positioned closer to the vehicle interior material 130 than the second housing 312. Therefore, sound generated based on the vibration of one or more of the first vibration device 333 and the second vibration device 335 can be output to the interior space IS of the vehicle 10, and thus, sound including the bass vocal cords can be output to the interior space IS of the vehicle 10.

[0186] The first housing 311 may include a ramp surface (or inclined surface) 311s and an inner surface 311i. The ramp surface 311s may be configured to slope between the opening 310o of the first housing 311 and the inner surface 311i. The ramp surface 311s may be configured to guide sound generated based on the vibration of the sound generation module 330 into the interior space IS of the vehicle 10. Therefore, sound generated based on the vibration of the sound generation module 330 can be output to the interior space IS of the vehicle 10, and the sound characteristics and / or sound pressure level characteristics of the sound, including the low-pitched vocal cords, can be further enhanced. For example, the ramp surface 311s may be a guiding surface or a sound guiding surface, but embodiments of this disclosure are not limited thereto.

[0187] The vibrating member 331 may be disposed or configured to be spaced apart from the opening 310o.

[0192] The second coupling member 322 may be located between the vibrating member 331 and the second housing 312. The second coupling member 322 may be located between the peripheral portion of the vibrating member 331 and the peripheral portion of the second housing 312.

[0195] The sound device 30 according to embodiments of the present disclosure may include a sound generation module 330 having a dual piezoelectric crystal structure, and therefore, the sound characteristics and / or sound pressure level characteristics of the sound including the bass vocal cords can be enhanced. Since the sound device 30 according to embodiments of the present disclosure includes a housing 310 containing an opening 310o, the air pressure in the internal space 313 of the housing 310 can be reduced, and therefore, the vocal cords of the bass vocal cords can be expanded, thereby improving the sound characteristics and / or sound pressure level characteristics of the bass vocal cords.

[0196] In various embodiments of this disclosure, multiple sound devices 30 can be configured and arranged in various ways. For example, two or more sound devices can be stacked on top of each other or arranged side by side.

[0214] According to embodiments of this disclosure, the soft component 360 can be configured as a different material from the connecting component 350. The elasticity (or Young's modulus) of the soft component 360 can be configured as a material with a different elasticity (or Young's modulus) than that of the connecting component 350. For example, the soft component 360 can be configured as a material with low elasticity. The soft component 360 can be configured as a soft material. For example, the soft component 360 can be ethylene propylene rubber or polyurethane rubber, but embodiments of this disclosure are not limited thereto. For example, the ethylene propylene rubber can be ethylene propylene diene monomer (EPDM), and as the foaming rate varies in EPDM, the ethylene propylene rubber can be configured as EPDM with low elasticity, but embodiments of this disclosure are not limited thereto.

For example, the soft component 360 may also include a hole 360o connected to the opening 310o. The hole 360o may be configured to correspond to the opening 310o. Therefore, sound based on the vibration of the sound generation module 330 can be output to the interior space IS of the vehicle 10 via the opening 310o and the hole 360o. The hole 360o may have the same shape as the opening 310o, but embodiments of this disclosure are not limited thereto.

For example, the soft component 360 may be a porous component, a buffer component, or a protective component, etc., but embodiments of this disclosure are not limited thereto.

[0216] In various embodiments of this disclosure, the sizes of the holes in the components may be different or the same. For example, the hole 310o of the first housing 311 may be the same or similar in size to the hole 360o of the soft member 360, but the embodiments of this disclosure are not limited thereto. For example, the size of the hole 310o may be different from the size of the hole 360o. In various embodiments of this disclosure, the hole 360o of the soft member 360 may be larger than or equal to the hole 310o of the first housing. When larger, the hole 360o allows sound to be emitted better from the housing 310, but when smaller, the hole 360o can regulate the amount of sound emitted. In various embodiments of this disclosure, at least one of the sizes of the holes 310o and 360o can be arbitrarily varied to increase or decrease in real time, for example by using a cover that can be closed or opened, or by changing the size of each of the holes 310o and 360o to regulate the sound emitted from the housing 310. Furthermore, the holes 310o and 360o do not need to be aligned or overlapped, but may partially overlap or may be offset from each other. When they are offset from each other, there is a connecting hole extending from hole 310o to hole 360o to allow sound to be emitted from housing 310.

[0217] In various embodiments of this disclosure, the shapes of holes 310o and 360o may correspond to those discussed below, but the embodiments of this disclosure are not limited thereto. For example, in various embodiments, the shapes of holes 310o and 360o may be different from each other. Furthermore, the shapes of holes 310o and 360o can be changed in real time by using a cover such as an iris diaphragm or a rotating diaphragm.

[0362] According to another embodiment of this disclosure, the sound device 30 may also include a connecting member 380.

[0363] According to another embodiment of this disclosure, the connecting member 380 can be disposed or configured between the vehicle interior material 130 and the sound generation module 330. The connecting member 380 can be configured between the first housing 311 and the vehicle interior material 130. For example, the first housing 311 may include an inner surface 311i and an outer surface. The inner surface 311i of the first housing 311 may face the vibrating member 331. The outer surface of the first housing 311 may be the surface of the first housing 311 opposite to the inner surface 311i.

[0364] The connecting member 380 may include a material different from at least one of the first coupling member 321 and the second coupling member 322. For example, the connecting member 380 may include a material having an adhesive force different from that of at least one of the first coupling member 321 and the second coupling member 322. Because the connecting member 380 includes a material having an adhesive force different from that of at least one of the first coupling member 321 and the second coupling member 322, the process of separating or removing (or reworking) the connecting member 380 from the vehicle interior material 130 can be easily performed.

[0365] The connecting member 380 may be coupled (or attached) to the rear surface of the housing 310 and may contact (or surface-contact) the first surface 130s1 of the vehicle interior material 130, but embodiments of this disclosure are not limited thereto. For example, when the connecting member 380 is coupled (or attached) to the rear surface of the housing 310 and simply contacts (or surface-contacts) the first surface 130s1 of the vehicle interior material 130, the process of separating or removing (or reworking) the connecting member 380 from the vehicle interior material 130 can be easily performed without damaging the sound device 30 or the vehicle interior material 130 during the separation and disassembly (or rework) of the sound device 30 from the vehicle interior material 130.

[0366] According to another embodiment of this disclosure, the connecting member 380 may include single-sided adhesive tape, single-sided adhesive tape, single-sided foam tape, single-sided foam tape, single-sided pad, single-sided foam pad, single-sided foam pad, single-sided pad component, single-sided cushioning component, single-sided cushioning pad, or single-sided cushioning tape, etc., but the embodiments of this disclosure are not limited to these. For example, the connecting member 380 may include rubber, but the embodiments of this disclosure are not limited to these. For example, the rubber may be ethylene propylene diene rubber (or ethylene propylene diene rubber M grade rubber), ethylene propylene rubber, or polyurethane rubber, but the embodiments of this disclosure are not limited to these. For example, the ethylene propylene rubber may be ethylene propylene diene monomer (EPDM), but the embodiments of this disclosure are not limited to these. For example, the hardness of EPDM may be 40 to 90, but the embodiments of this disclosure are not limited to these. For example, the tensile strength of EPDM may be 50 kg / cm². 2 Up to 200kg / cm 2 However, the embodiments of this disclosure are not limited thereto. For example, the connecting member 380 may include highly elastic rubber or low-elastic rubber, but the embodiments of this disclosure are not limited thereto. According to the embodiments of this disclosure, because the connecting member 380 includes rubber or the like, vibration loss can be prevented or minimized when vibration of the housing 310 or the first housing 311 is transmitted to the internal material 130, and therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be further improved.

[0367] According to embodiments of the present disclosure, the first coupling member 321 and the second coupling member 322 of the coupling member 320 may include adhesives, double-sided tape, double-sided adhesive tape, double-sided foam tape, double-sided foam tape, double-sided pad, double-sided foam pad, double-sided foam pad, double-sided pad component, double-sided cushioning component, double-sided cushioning pad or double-sided cushioning tape, etc., but the embodiments of the present disclosure are not limited thereto.

[0368] According to embodiments of this disclosure, the connecting member 380 may include a material different from the material of at least one of the first adhesive member 332 and the second adhesive member 334. For example, at least one of the first adhesive member 332 and the second adhesive member 334 may include an adhesive, double-sided tape, double-sided tape, double-sided foam tape, double-sided foam pad, double-sided cushioning tape, or adhesive sheet, but embodiments of this disclosure are not limited thereto.

[0370] The hole 380o can be configured to correspond to (or overlap with) the opening 310o. The hole 380o can have the same shape as the opening 310o, but embodiments of this disclosure are not limited thereto. For example, the hole 380o can have the same shape as the opening 310o, but can have a larger size than the opening 310o. Therefore, sound based on the vibrations of the sound generation module 330 can be output to the interior space IS of the vehicle through (or by means of) the opening 310o and the hole 380o. For example, the hole 380o can be an opening, a slot, a groove, a connecting hole, or an intermediate hole, but embodiments of this disclosure are not limited thereto.

[0371] According to embodiments of this disclosure, the hole 380o may correspond to (or overlap with) the hole 135 of the vehicle interior material 130. The hole 380o may be located between the hole 135 of the vehicle interior material 130 and the opening 310o of the housing 310. For example, the hole 380o may be located between the hole 135 of the vehicle interior material 130 and the opening 310o of the first housing 311. The hole 380o may be connected to the opening 310o of the housing 310. For example, the hole 380o may be connected to the opening 310o of the first housing 311. The hole 380o may be configured to correspond to the opening 310o. The hole 380o of the connecting member 380 may have the same size as each of the opening 310o and the hole 135, or it may have a larger size than each of the opening 310o and the hole 135. Therefore, the sound based on the vibration of the sound generation module 330 can be output to the interior space IS of the vehicle through (or by means of) the opening 310o, the hole 380o and the hole 135.

The connecting member 380 may directly contact at least one or more curved portions 136. For example, the connecting member 380 may directly contact at least one or more curved portions 136 without a medium or intermediate member.

[0375] The sound device 30 or housing 310 may be connected or coupled to at least one or more curved portions 136 of the vehicle interior material 130 via a connecting member 380. For example, the connecting member 380 may be disposed between the housing 310 and at least one or more curved portions 136 of the vehicle interior material 130.

For example, the first housing 311 may be connected or coupled to at least one or more curved portions 136 of the vehicle interior material 130 via the connecting member 380.

[0376] According to embodiments of this disclosure, sound based on vibrations of the sound generation module 330 can be output to the interior space of the vehicle via (or by means of) the opening 310o, the hole 380o, and the second hole 135. Furthermore, vibrations of the housing 310 or the first housing 311 based on the sound (or sound pressure level or sound wave) generated by the sound generation module 330 can be effectively transmitted via the connecting member 380 to the vehicle interior material 130, which includes at least one or more curved portions 136, without vibration loss.

Figures 27 to 30 The interior of a sound device according to another embodiment of this disclosure is shown. Figures 26 to 30 It is shown that at least one of the holes is added to the reference above. Figures 1 to 25C The following describes an embodiment of the sound device 30. Therefore, in the following description, at least one hole will be described in detail, and other elements will be provided by... Figures 1 to 25C The same reference numerals refer to the same items, and repeated descriptions are omitted or given briefly.

[0379] Reference Figure 26 According to another embodiment of the present disclosure, the sound device 30 may also include at least one or more holes 331o.

[0380] At least one or more holes 331o may be disposed at the vibrating member 331. At least one or more holes 331o may be disposed through the vibrating member 331. At least one or more holes 331o may be disposed through the vibrating member 331 in the thickness direction Z of the vibrating member 331. For example, at least one or more holes 331o may be formed to vertically pass through the vibrating member 331 in the thickness direction Z of the vibrating member 331.

[0381] The sound generation module 330 according to embodiments of the present disclosure may include a vibrating component 331 having at least one or more holes 331o and vibrating devices 333 and 335 disposed on the vibrating component 331.

[0382] At least one or more holes 331o can be configured to regulate the flow of air within the internal space 313 of the housing 310. For example, at least one or more holes 331o can perform control to allow air to flow within the internal spaces 313 of the housing 310 that are spatially separated from each other by a vibrating member 331. For example, at least one or more holes 331o can be configured to regulate the flow of air within the internal space 313 of the housing 310 between a first space 313a and a second space 313b that are spatially separated from each other by a vibrating member 331. For example, at least one or more holes 331o can be a first hole, a vent hole, an airflow hole, a ventilation hole, a pipe hole, a first connection hole, a first connecting hole, or a first spatial connection portion, but the embodiments disclosed are not limited thereto.

[0383] At least one or more holes 331o according to embodiments of the present disclosure may be configured in a polygonal shape, such as a circular shape, an elliptical shape or a quadrilateral shape, but embodiments of the present disclosure are not limited thereto.

[0384] At least one or more holes 331o can be configured to reduce the air pressure in the internal space 313 of the housing 310. For example, at least one or more holes 331o can be configured to connect a first space 313a and a second space 313b, which are spatially separated by the vibrating member 331, within the internal space 313 of the housing 310. For example, the first space 313a and the second space 313b in the internal space 313 of the housing 310 can be connected (interconnected) to each other through at least one or more holes 331o. For example, at least one or more holes 331o can be configured to reduce the air pressure in the first space 313a of the first housing 311 or the first space 313a disposed between the vibrating member 331 and the first housing 311. Therefore, the frequency band (reproduction band) of the bass tone band can be extended, and thus the sound characteristics and / or sound pressure level characteristics of the bass tone band can be improved. Furthermore, the sound generation module 330 can vibrate more stably through at least one or more holes 331o in the vibrating member 331, and thus, the sound characteristics and / or sound pressure level characteristics can be further improved.

[0385] According to embodiments of this disclosure, the internal space 313 may be located between the first surface of the sound generation module 330 and the first housing 311, and may be connected to the opening 310o. The internal spaces 313 may be connected to each other through at least one or more holes 331o. The housing 311 may include a second space 313b between the second housing 312 and the second surface of the sound generation module 330 opposite to the first surface. The internal spaces 313 and the second space 313b may be connected to each other through at least one or more holes 331o.

[0386] According to embodiments of this disclosure, at least one or more holes 331o may be configured adjacent to the vibrating devices 333 and 335. For example, at least one or more holes 331o may be configured at the periphery of each vibrating device 333 and 335. For example, at least one or more holes 331o may be configured adjacent to the side surface of each of the vibrating devices 333 and 335. For example, the distance between at least one or more holes 331o and each of the vibrating devices 333 and 335 may be less than the distance between at least one or more holes 331o and the sidewall (or side surface) of the housing 310. For example, when at least one or more holes 331o are configured at a location away from each of the vibrating devices 333 and 335, the sound characteristics and / or sound pressure level characteristics of the bass vocal cords may be further improved.

[0387] According to embodiments of this disclosure, at least one or more holes 331o may be configured at a vibrating member 331 adjacent to vibrating devices 333 and 335, wherein vibrating devices 333 and 335 are located between at least one or more holes 331o and vibrating member 331. For example, vibrating member 331 may include a first peripheral region adjacent to a first side surface of each of the vibrating devices 333 and 335, and a second peripheral region opposite to a second side of each of the vibrating devices 333 and 335 opposite to the first side. For example, with respect to a first direction X, vibrating member 331 may include a first peripheral region, a vibration region, and a second peripheral region. For example, in vibrating member 331, each of the first peripheral region and the second peripheral region may be a hole region or a non-arrangement region of each of the vibrating devices 333 and 335, and the vibration region may be an arrangement (or setting) region of the vibrating devices 333 and 335. For example, at least one or more holes 331o may be configured in each of the first and second peripheral regions of the vibrating member 331 to have a symmetrical structure (or a horizontally symmetrical structure or a left-right symmetrical structure) or an asymmetrical structure (or a horizontally asymmetrical structure or a left-right asymmetrical structure) with respect to the vibrating devices 333 and 335.

[0388] According to embodiments of this disclosure, vibration devices 333 and 335 each include a long side and a short side. The distance (or separation distance or shortest distance) between at least one or more holes 331o and the short side of vibration devices 333 and 335 can represent the ratio of the short side lengths of vibration devices 333 and 335. According to embodiments of this disclosure, the distance between at least one or more holes 331o and vibration devices 333 and 335 can be 60% or less of the short side lengths of vibration devices 333 and 335.

[0389] Reference Figure 26 and Figure 27 At least one or more holes 331o can be positioned closer to the vibrating devices 333 and 335 than the coupling member 320. The coupling member 320 may include a first coupling member 321 and a second coupling member 322. For example, at least one or more holes 331o can be positioned closer to the vibrating devices 333 and 335 than the first coupling member 321 and the second coupling member 322. Therefore, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be enhanced. (Refer to the following...) Figure 48A and Figure 48B Describe the sound output characteristics based on the distance between the vibrating devices 333 and 335 and at least one or more holes 331o.

[0390] According to embodiments of this disclosure, at least one or more holes 331o do not overlap with the opening 310o. For example, at least one or more holes 331o may be configured to be spaced apart from the opening 310o. Therefore, sound generated in the second space 313b based on the vibration (or drive) of each of the vibration devices 333 and 335 can be output to the first space 313a through at least one or more holes 331o, and the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal cords can be enhanced.

[0391] Reference Figure 26 and Figure 28 The dimensions of at least one or more holes 331o may differ from those of other holes. Figure 27 The dimensions of at least one or more apertures 331o are shown. As the size of at least one or more apertures 331o increases, the sound characteristics and / or sound pressure level characteristics of the bass-tone vocal cords increase. For example, the distance between at least one or more apertures 331o and the vibrating devices 333 and 335 can be less than the distance between at least one or more apertures 331o and the sidewalls (or side surfaces) of the housing 310. For example, as the size of at least one or more apertures 331o increases, the sound pressure level characteristics of the bass-tone vocal cords at 400Hz or lower can be further enhanced. Reference will be made below. Figure 47A , Figure 47B and Figure 49Describe the sound output characteristics based on the dimensions of at least one or more holes 331o.

[0392] Reference Figure 26 and Figure 29 At least one or more holes 331o may be configured to have two holes 331o. For example, the sound device 30 according to an embodiment of the present disclosure may also include two holes 331o. The two holes 331o may be configured to be adjacent to each other. For example, the two holes 331o may be configured to be adjacent to the vibrating devices 333 and 335. For example, the distance between each of the two holes 331o and the vibrating devices 333 and 335 may be different. For example, the two holes 331o may be configured parallel in a first direction X to be adjacent to the vibrating devices 333 and 335. For example, the distance between each of the two holes 331o and the vibrating devices 333 and 335 may be equal to each other. For example, each of the two holes 331o may be configured to be adjacent to the vibrating devices 333 and 335. For example, the two holes 331o may be configured parallel in a second direction Y to be adjacent to the vibrating devices 333 and 335.

[0393] Each of the two holes 331o according to embodiments of the present disclosure may be configured in a polygonal shape, such as a circular shape, an elliptical shape, or a quadrilateral shape, but embodiments of the present disclosure are not limited thereto.

[0394] Reference Figure 26 and Figure 30 At least one or more holes 331o can be configured in a quadrilateral shape. For example, at least one or more holes 331o can be configured adjacent to vibration devices 333 and 335. (Refer to the following...) Figure 50 Describe the sound output characteristics based on the shape of at least one or more holes 331o.

[0395] Reference Figures 27 to 30 One or more holes 331o may have straight or vertical hole walls, such that any polygonal shape in the polygonal shape has a constant cross-sectional shape. For example, when one or more holes 331o are circular, one or more holes 331o may be cylindrical in cross-section, but embodiments of this disclosure are not limited thereto. For example, the hole walls may have a shape that changes from a top (or first) opening to a bottom (or second) opening of one or more holes. In various embodiments of this disclosure, the top opening may refer to the opening of the hole 331o facing the second housing 312, and the bottom opening may refer to the opening of the hole 331o facing the first housing 311.

[0396] In embodiments of this disclosure, the shape of the orifice wall may become narrower as it travels from the top opening to the bottom opening or from the bottom opening to the top opening. In various embodiments of this disclosure, the sizes or areas of the top and bottom openings may differ from each other, or they may be the same. At different times, the top opening may be smaller than the bottom opening, or vice versa.

[0397] In various embodiments of this disclosure, the shape (or width or diameter) of the hole wall may be widest at the top and bottom openings and gradually decrease towards the center of the hole 331o, or it may be widest at the center and gradually decrease towards the top and bottom openings. The change in hole wall width is not necessarily gradual, and one or more steps or bends may exist within the hole wall of the hole 331o. In various embodiments of this disclosure, the cross-sectional shape of the hole wall may be triangular or curved, concave or convex, or various combinations thereof, but is not limited thereto. Furthermore, when multiple holes 331o exist, the cross-sectional shapes of the hole walls may be the same or different from each other.

[0398] In addition, the second housing 312 may include a hole similar to the hole 310o of the opening portion of the first housing 311.

[0399] According to embodiments of this disclosure, at least one or more holes 331o can output sound (or rear sound) generated based on the vibration of each of the vibrating devices 333 and 335, and released through the opening 310o of the first housing 311 to the rear surface (or rearward direction) of the vibrating member 331. Therefore, sound generated at the rear surface of the vibrating member 331 or the second space 313b of the housing 310 based on the vibration (or drive) of each of the vibrating devices 333 and 335 can be output to the first space 313a through at least one or more holes 331o, and can be output (or radiated) through the opening 310o of the first housing 311 and the hollow portion 501 of the coupling portion 500, thus further enhancing the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band. According to embodiments of this disclosure, the sound characteristics and / or sound pressure level characteristics of the low-pitched vocal band (e.g., 400 Hz or lower) can be further enhanced.

Therefore, the process of attaching or mounting the sound device 30 to or separating or attaching / removing the sound device 30 from the vehicle interior material 130 can be easily performed.

[0410] According to another embodiment of this disclosure, each of the connecting member 380 and the first coupling member 321 can be coupled to...

For example, the protective member 410 may include a material having an adhesive force different from that of the first coupling member 321. The protective member 410 may include a material having an adhesive force different from that of the first coupling member 321, and therefore, the protective member 410 can protect the sound device 30. For example, the protective member 410 may include rubber such as EPDM, and therefore, the sound pressure level of the bass vocal cords can be enhanced and the sound device 30 can be protected.

Figure 35 The cross-sectional view taken by line I-I' is shown. Figure 37 It is based on the implementation of this disclosure. Figure 35 The cross-sectional view taken from line II-II' is shown.

[0438] Reference Figures 35 to 37 According to embodiments of this disclosure, the sound generation module 330 may include vibration devices 333 and 335. Vibration devices 333 and 335 may include one or more vibration generators 1310.

[0439] Vibration generator 1310 may include a piezoelectric material with piezoelectric properties. Vibration generator 1310 can vibrate (or displace or drive) a vibrating member (or vehicle interior material) based on vibration (or displacement or drive) of the piezoelectric material in response to an electrical signal (or speech signal or sound signal) applied to the piezoelectric material. For example, vibration generator 1310 can vibrate (or displace or drive) by alternately and repeatedly contracting and / or expanding through a piezoelectric effect (or piezoelectric property). For example, vibration generator 1310 can vibrate (or displace or drive) in the vertical direction (or thickness direction) Z by alternately and repeatedly contracting and / or expanding through a reverse piezoelectric effect. For example, in vibration generator 1310, a piezoelectric material including piezoelectric ceramics can vibrate or mechanically displace (or vibrate or drive) in response to an externally applied electrical signal.

[0440] The vibration generator 1310 can be configured as a ceramic-based piezoelectric material capable of achieving relatively strong vibrations, or it can be configured as a piezoelectric ceramic having a perovskite-based crystal structure. For example, the vibration generator 1310 can be a vibration generating device, a vibration membrane, a vibration generating membrane, a vibrator, an active vibrator, an active vibration generator, an actuator, an exciter, a membrane actuator, a membrane exciter, an ultrasonic actuator, or an active vibration component, etc., but the embodiments of this disclosure are not limited thereto.

[0442] The vibration generating unit 1311 can be configured to vibrate based on a driving signal via the piezoelectric effect. For example, the vibration generating unit 1311 may include a piezoelectric type vibration unit or a piezoelectric vibration unit. The vibration generating unit 1311 may include at least one or more of piezoelectric inorganic materials and piezoelectric organic materials. For example, the vibration generating unit 1311 may be a vibration device, a piezoelectric device, a piezoelectric device section, a piezoelectric device layer, a piezoelectric structure, a piezoelectric vibration unit, or a piezoelectric vibration layer, etc., but the embodiments of this disclosure are not limited thereto.

[0444] The vibrating part 1311a may comprise a piezoelectric material or an electroactive material that includes a piezoelectric effect. For example, a piezoelectric material may have the property that when pressure or torsion is applied to the crystal structure by an external force, a potential difference arises due to dielectric polarization caused by the change in the relative positions of positive (+) ions and negative (-) ions, and thus vibration is generated by an electric field based on the reverse voltage applied thereto. For example, the vibrating part 1311a may be a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a piezoelectric composite layer, a piezoelectric composite, or a piezoelectric ceramic composite, etc., but embodiments of the present disclosure are not limited thereto.

[0445] The vibrating part 1311a can be configured as a ceramic matrix material capable of achieving relatively strong vibrations, or it can be configured as a piezoelectric ceramic having a perovskite-based crystal structure. The perovskite-based crystal structure can have a piezoelectric effect and / or a reverse piezoelectric effect, and can be an oriented or aligned plate-like structure. The perovskite-based crystal structure can be represented by the chemical formula "ABO3". In the chemical formula, "A" can include a divalent metal element, and "B" can include a tetravalent metal element. As an embodiment of this disclosure, in the chemical formula "ABO3", "A" and "B" can be cations, and "O" can be anion. For example, the vibrating part 1311a can contain at least one or more of lead titanate (PbTiO3), lead zirconate (PbZrO3), lead zirconate titanate (PbZrTiO3), barium titanate (BaTiO3), and strontium titanate (SrTiO3), but the embodiments of this disclosure are not limited thereto.

For example, the vibrating part 1311a may contain at least one or more of calcium titanate (CaTiO3), BaTiO3 and SrTiO3 that do not contain lead (Pb), but the embodiments of this disclosure are not limited thereto.

[0447] The first electrode portion 1311b may be disposed on the first surface (or upper surface or front surface) 1311s1 of the vibrating portion 1311a. The first electrode portion 1311b may have the same size as the vibrating portion 1311a, or it may have a smaller size than the vibrating portion 1311a.

[0448] The second electrode portion 1311c may be disposed at a second surface (or lower surface or rear surface) 1311s2 of the vibrating portion 1311a that is opposite to or different from the first surface 1311s1. The second electrode portion 1311c may have the same size as the vibrating portion 1311a, or it may have a smaller size than the vibrating portion 1311a. For example, the second electrode portion 1311c may have the same shape as the vibrating portion 1311a, but the embodiments of this disclosure are not limited thereto.

[0449] According to embodiments of this disclosure, to prevent electrical short circuits between the first electrode portion 1311b and the second electrode portion 1311c, each of the first electrode portion 1311b and the second electrode portion 1311c may be formed on the remaining portion other than the peripheral portion of the vibrating portion 1311a. For example, the first electrode portion 1311b may be formed on the entire remaining portion other than the peripheral portion of the first surface 1311s1 of the vibrating portion 1311a. For example, the second electrode portion 1311c may be formed on the entire remaining portion other than the peripheral portion of the second surface 1311s2 of the vibrating portion 1311a. For example, the distance between the lateral surface (or sidewall) of each of the first electrode portion 1311b and the second electrode portion 1311c and the lateral surface (or sidewall) of the vibrating portion 1311a may be at least 0.5 mm or greater. For example, the distance between the lateral surface of each of the first electrode portion 1311b and the second electrode portion 1311c and the lateral surface of the vibration portion 1311a can be at least 1 mm or more, but the embodiments of this disclosure are not limited thereto.

[0450] One or more of the first electrode portion 1311b and the second electrode portion 1311c according to embodiments of the present disclosure may be formed of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, the transparent or semi-transparent conductive material may include indium tin oxide (ITO) or indium zinc oxide (IZO), but embodiments of the present disclosure are not limited thereto. The opaque conductive material may include gold (Au), silver (Ag), platinum (Pt), palladium (Pd), molybdenum (Mo), magnesium (Mg), carbon, or silver (Ag) containing glass frit, or may be made of alloys thereof, but embodiments of the present disclosure are not limited thereto. For example, to enhance the electrical and / or vibrational properties of the vibrating portion 1311a, each of the first electrode portion 1311b and the second electrode portion 1311c may contain silver (Ag) with low resistivity. For example, carbon may include one or more of carbon black, ketjen black, carbon nanotubes, and carbon materials including graphite, but embodiments of the present disclosure are not limited thereto.

[0451] The vibrating section 1311a can be polarized (or polarized) by applying a specific voltage to the first electrode section 1311b and the second electrode section 1311c in a specific temperature atmosphere or a temperature atmosphere that can be changed from high temperature to room temperature, but the embodiments of the present disclosure are not limited to this. For example, the polarization direction (or polarization direction) formed in the vibrating section 1311a can be formed or aligned (or arranged) from the first electrode section 1311b to the second electrode section 1311c, but the embodiments of the present disclosure are not limited to this. For example, the polarization direction (or polarization direction) formed in the vibrating section 1311a can be formed or aligned (or arranged) from the second electrode section 1311c to the first electrode section 1311b.

[0452] The vibrating section 1311a can vibrate by alternately and repeatedly contracting and / or expanding through a reverse piezoelectric effect based on a driving signal applied externally to the first electrode section 1311b and the second electrode section 1311c. For example, the vibrating section 1311a can vibrate in the vertical (or thickness) and planar directions by signals applied to the first electrode section 1311b and the second electrode section 1311c. The vibrating section 1311a can be displaced (or vibrated or driven) by contraction and / or expansion in the planar direction, thereby improving the vibration characteristics, including the sound characteristics and / or sound pressure level characteristics of the vibration generator 1310.

[0453] The vibration generator 1310 according to embodiments of the present disclosure may further include a first cover member 1313 and a second cover member 1315.

[0454] The first cover member 1313 may be disposed on the first surface of the vibration generating portion 1311. For example, the first cover member 1313 may be configured to cover the first electrode portion 1311b of the vibration generating portion 1311. For example, the first cover member 1313 may be located at the first electrode portion 1311b. For example, the first cover member 1313 may be configured to have a size larger than the vibration generating portion 1311. The first cover member 1313 may be configured to protect the first surface of the vibration generating portion 1311 and the first electrode portion 1311b.

[0455] The second cover member 1315 may be disposed on the second surface of the vibration generating portion 1311. For example, the second cover member 1315 may be configured to cover the second electrode portion 1311c of the vibration generating portion 1311. For example, the second cover member 1315 may be located at the second electrode portion 1311c. For example, the second cover member 1315 may be configured to have a larger size than the vibration generating portion 1311, and may be configured to have the same size as the first cover member 1313. The second cover member 1315 may be configured to protect the second surface of the vibration generating portion 1311 and the second electrode portion 1311c.

[0456] The first cover member 1313 and the second cover member 1315 according to embodiments of this disclosure may comprise the same material or different materials. For example, each of the first cover member 1313 and the second cover member 1315 may be a polyimide (PI) film, a polyethylene terephthalate (PET) film, or a polyethylene naphthalate (PEN) film, but embodiments of this disclosure are not limited thereto.

[0457] The first cover member 1313 can be connected or coupled to the first surface of the vibration generating part 1311 or the first electrode part 1311b via the first adhesive layer 1317. For example, the first cover member 1313 can be connected or coupled to the first surface of the vibration generating part 1311 or the first electrode part 1311b via a film lamination process using the first adhesive layer 1317.

[0458] The second cover member 1315 can be connected or coupled to the second surface of the vibration generating part 1311 or the second electrode part 1311c via the second adhesive layer 1319. For example, the second cover member 1315 can be connected or coupled to the second surface of the vibration generating part 1311 or the second electrode part 1311c via a film lamination process using the second adhesive layer 1319.

[0459] Each of the first adhesive layer 1317 and the second adhesive layer 1319 according to embodiments of this disclosure may include an electrically insulating material that is adhesive and capable of compression and decompression. For example, each of the first adhesive layer 1317 and the second adhesive layer 1319 may contain epoxy resin, acrylic resin, silicone resin, polyurethane resin, acrylic polymer, silicone polymer, or polyurethane polymer, but embodiments of this disclosure are not limited thereto.

[0460] The first adhesive layer 1317 and the second adhesive layer 1319 may be disposed between the first cover member 1313 and the second cover member 1315 to surround the vibration generating portion 1311. For example, one or more of the first adhesive layer 1317 and the second adhesive layer 1319 may be configured to partially or completely surround the vibration generating portion 1311.

[0461] Either the first cover member 1313 or the second cover member 1315 can be passed through Figures 3 to 32 The adhesive members 332 and 334 shown are connected or coupled to the vibrating member 331.

[0462] The vibration generator 1310 according to embodiments of this disclosure may also include a signal supply component 1320.

[0463] The signal supply component 1320 can be configured to supply a drive signal from the drive circuit section to the vibration generation section 1311. The signal supply component 1320 can be configured to be electrically connected to the vibration section 1311a. The signal supply component 1320 can be configured to be electrically connected to the first electrode section 1311b and the second electrode section 1311c of the vibration generation section 1311.

[0464] A portion of the signal supply member 1320 can be accommodated (or inserted) between the first cover member 1313 and the second cover member 1315. An end portion (or distal portion or one side) of the signal supply member 1320 can be disposed or inserted (or accommodated) between an edge portion (or a peripheral portion) of the first cover member 1313 and an edge portion (or a peripheral portion) of the second cover member 1315. An edge portion of the first cover member 1313 and an edge portion of the second cover member 1315 can accommodate or vertically (or vertically) cover the end portion (or distal portion or one side) of the signal supply member 1320. Therefore, the signal supply member 1320 can be integrated (or configured) integrally with the vibration generating unit 1311. Therefore, the sound generating module 330 or vibration devices 333 and 335 can be implemented (or configured) as a membrane type integrated with the signal supply member 1320. For example, the signal supply member 1320 can be configured as a part (or component) of the vibration generating unit 1311, thereby achieving the effect of a single material. For example, the signal supply component 1320 may be configured as a signal cable, a flexible cable, a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multilayer printed circuit, or a flexible multilayer printed circuit board, but the embodiments of this disclosure are not limited thereto.

[0465] The signal supply component 1320 according to embodiments of the present disclosure may include a base component 1321 and a plurality of signal lines 1323a and 1323b. For example, the signal supply component 1320 may include the base component 1321, a first signal line 1323a, and a second signal line 1323b.

[0466] The base component 1321 may include transparent or opaque plastic material, but embodiments of this disclosure are not limited thereto. The base component 1321 may have a certain width along the first direction X, and may extend a considerable length along the second direction Y intersecting the first direction X.

[0467] The first signal line 1323a and the second signal line 1323b can be disposed on a first surface of the base member 1321 parallel to the second direction Y, and can be spaced apart from each other or electrically separated from each other along the first direction X. The first signal line 1323a and the second signal line 1323b can be disposed parallel to each other on the first surface of the base member 1321. For example, the first signal line 1323a and the second signal line 1323b can be implemented in a line shape by patterning a metal layer (or conductive layer) formed or deposited on the first surface of the base member 1321.

[0468] The end portions (or distal portions or one side) of the first signal line 1323a and the second signal line 1323b can be separated from each other and therefore can be bent or folded individually.

[0469] The end portion (or distal portion or one side) of the first signal line 1323a may be electrically connected to the first electrode portion 1311b of the vibration generating unit 1311. For example, the end portion of the first signal line 1323a may be electrically connected to at least a portion of the first electrode portion 1311b of the vibration generating unit 1311 at an edge portion of the first cover member 1313. For example, the end portion (or distal portion or one side) of the first signal line 1323a may be electrically connected and directly connected to at least a portion of the first electrode portion 1311b of the vibration generating unit 1311. For example, the end portion (or distal portion or one side) of the first signal line 1323a may be electrically connected to or directly contact the first electrode portion 1311b of the vibration generating unit 1311. For example, the end portion of the first signal line 1323a may be electrically connected to the first electrode portion 1311b via conductive double-sided adhesive tape. Therefore, the first signal line 1323a can be configured to transmit the first drive signal supplied from the drive circuit section (or vibration driver) to the first electrode section 1311b of the vibration generation section 1311.

[0470] The end portion (or distal portion or one side) of the second signal line 1323b can be electrically connected to the second electrode portion 1311c of the vibration generating unit 1311. For example, the end portion of the second signal line 1323b can be electrically connected to at least a portion of an edge portion of the second electrode portion 1311c of the vibration generating unit 1311 on the second cover member 1315. For example, the end portion of the second signal line 1323b can be electrically connected and directly connected to at least a portion of the second electrode portion 1311c of the vibration generating unit 1311. For example, the end portion of the second signal line 1323b can be electrically connected to or directly contact the second electrode portion 1311c of the vibration generating unit 1311. For example, the end portion of the second signal line 1323b can be electrically connected to the second electrode portion 1311c via conductive double-sided adhesive tape. Therefore, the second signal line 1323b can be configured to transmit a second drive signal supplied from the drive circuit unit (or vibration driver) to the second electrode portion 1311c of the vibration generating unit 1311.

[0471] The signal supply component 1320 according to embodiments of this disclosure may further include an insulating layer 1325.

[0472] An insulating layer 1325 may be disposed on a first surface of the base member 1321 to cover each of the first signal line 1323a and the second signal line 1323b except for the end portion (or one side) of the signal supply member 1320.

[0473] The signal supply component 1320, including the end portion (or one side) of the base component 1321 and the end portion (or one side) of the insulating layer 1325, and the end portion (or one side) of 1325a, can be inserted (or accommodated) between the first cover component 1313 and the second cover component 1315, and can be fixed between the first cover component 1313 and the second cover component 1315 by the first adhesive layer 1317 and the second adhesive layer 1319. Therefore, the end portion (or one side) of the first signal line 1323a can remain electrically connected to the first electrode portion 1311b of the vibration generating part 1311, and the end portion (or one side) of the second signal line 1323b can remain electrically connected to the second electrode portion 1311c of the vibration generating part 1311. In addition, the end portion (or one side) of the signal supply member 1320 can be inserted (or accommodated) and fixed between the vibration generating part 1311 and the first cover member 1313, and thus, contact defects between the vibration generator 1310 and the signal supply member 1320 caused by the movement of the signal supply member 1320 can be prevented.

[0474] In the signal supply component 1320 according to an embodiment of the present disclosure, each of the end portion (or side) of the base component 1321 and the end portion (or side) 1325a of the insulating layer 1325 can be removed. For example, each of the end portions of the first signal line 1323a and the second signal line 1323b can be exposed to the outside without being supported or covered by each of the end portions (or side) of the base component 1321 and the end portions (or side) 1325a of the insulating layer 1325, respectively. For example, the end portion (or side) of each of the first signal line 1323a and the second signal line 1323b can protrude (or extend) from the end portion 1321e of the base component 1321 or the end portion 1325e of the insulating layer 1325 to have a certain length. Therefore, each of the end portions (or distal portions or sides) of each of the first signal line 1323a and the second signal line 1323b can be bent individually or independently.

[0475] The end portion (or one side) of the first signal line 1323a that is not supported by the end portion (or one side) of the base member 1321 and the end portion 1325a of the insulating layer 1325 can be directly connected to or directly contact the first electrode portion 1311b of the vibration generating unit 1311. The end portion (or one side) of the second signal line 1323b that is not supported by the end portion (or one side) of the base member 1321 and the end portion 1325a of the insulating layer 1325 can be directly connected to or directly contact the second electrode portion 1311c of the vibration generating unit 1311.

[0476] According to embodiments of this disclosure, a portion of the signal supply member 1320 or a portion of the base member 1321 may be disposed or inserted (or accommodated) between the first cover member 1313 and the second cover member 1315, and thus, the signal supply member 1320 may be integrated (or configured) integrally with the vibration generating unit 1311. Therefore, the vibration generating unit 1311 and the signal supply member 1320 may be configured as a single part (or component), and thus, the effect of a single material can be achieved.

[0477] According to embodiments of this disclosure, the first signal line 1323a and the second signal line 1323b of the signal supply component 1320 can be integrated (or configured) with the vibration generator 1310, and therefore, welding processes for the electrical connection between the vibration generator 1310 and the signal supply component 1320 are unnecessary. This simplifies the manufacturing process and structure of the vibration devices 333 and 335 and reduces the hazards associated with welding processes.

[0479] Reference Figure 36 and Figure 38 According to another embodiment of the present disclosure, the vibration unit 1311a may include a plurality of first portions 1311a1 and a plurality of second portions 1311a2.

For example, vibration devices 333 and 335 may include first vibration generators 333A and 335A and second vibration generators 333B and 335B.

[0496] The first vibration generators 333A and 335A, and the second vibration generators 333B and 335B, can overlap or stack each other to shift (or drive or vibrate) in the same direction to maximize the amplitude displacement of the vibration devices 333 and 335 or the amplitude displacement of the vibration member 331. For example, the first vibration generators 333A and 335A, and the second vibration generators 333B and 335B, can have substantially the same dimensions, but embodiments of this disclosure are not limited thereto. For example, the first vibration generators 333A and 335A, and the second vibration generators 333B and 335B, can have substantially the same dimensions within the tolerance range of the manufacturing process, but embodiments of this disclosure are not limited thereto. Therefore, the first vibration generators 333A and 335A, and the second vibration generators 333B and 335B can maximize the amplitude displacement of the vibration devices 333 and 335 and / or the amplitude displacement of the vibration member 331.

Figures 3 to 34 The adhesive members 332 and 334 shown are connected or coupled to the vibrating member 331. For example, the first vibration generators 333A and 335A can be connected or coupled to the vibrating member 331 via adhesive members 332 and 334.

[0498] Each of the first vibration generators 333A and 335A and the second vibration generators 333B and 335B can be compared with the above reference. Figures 33 to 39 The vibration generating part 1311 described is the same or substantially the same, and therefore the same reference numerals refer to the same elements, and repeated descriptions of it are omitted or will be briefly given below.

For example, intermediate components 333M and 335M may comprise foam pads, double-sided tape, double-sided foam tape, double-sided pads, double-sided foam pads, or adhesives, but embodiments of this disclosure are not limited thereto. For example, the adhesive layer of intermediate components 333M and 335M may comprise epoxy resin, acrylic resin, silicone resin, or polyurethane, but embodiments of this disclosure are not limited thereto. For example, the adhesive layer of intermediate components 333M and 335M may comprise a polyurethane-based material (or substance) having relatively ductile properties. Therefore, the vibration loss caused by displacement interference between the first vibration generators 333A and 335A and the second vibration generators 333B and 335B can be reduced or minimized, or each of the first vibration generators 333A and 335A and the second vibration generators 333B and 335B can be freely displaced (or vibrated or driven).
