[0003] Vehicles may contain a sound device that emits sound based on an audio signal output from a multimedia device, and such a sound device may include a vehicle audio unit. For example, the sound device applied to vehicles may include a front speaker and a rear speaker configured as a coil-type device. SUMMARY

[0004] However, a sound system in vehicles that produces realistic sound or multi-channel stereo sound through the front and rear speakers may be limited by the design of the speaker coil type. Furthermore, while a stereo sound system in vehicles can produce stereo sound even with an increased number of speakers, the size of the speakers (based on the design of the speaker coil type) and the limited space in vehicles restrict the ability to achieve realistic sound or stereo sound using a compact and aesthetically pleasing design.

[0005] The inventors of this disclosure recognized the problems and disadvantages of the related field and conducted extensive research and experiments to improve the sound characteristics and / or sound pressure level characteristics of a sound device for vehicles. Based on this extensive research and experimentation, the inventors invented a sound device and a vehicle device incorporating it, which are capable of improving the sound characteristics and / or sound pressure level characteristics.

[0124] Throughout the drawings and detailed descriptions, the same reference symbols should be understood as referring to the same elements, features, and structures, unless otherwise specified. The sizes, lengths, and thicknesses of layers, areas, and elements, and their representation, may be exaggerated for clarity, illustration, and / or as necessary. DETAILED DESCRIPTION

[0125] Now, specific reference is made to aspects of the revelation, for which examples may be illustrated in the accompanying drawings. In the following description, if a detailed description of known procedures, functions, or configurations might unnecessarily obscure aspects of the revelation, such a detailed description may be omitted for the sake of brevity. Furthermore, repeated descriptions may be omitted for the sake of brevity. The described progression of processing steps and / or operations is a non-limiting example.

[0126] The sequence of steps and / or operations is not limited to what is set forth here and may be modified to occur in an order different from that described herein, with the exception of steps and / or operations that necessarily occur in a specific order. In one or more examples, depending on a function or operation involved, two successive operations may be performed with substantial temporal overlap, or the two operations may be performed in reverse order or in a different order altogether.

[0127] Unless otherwise stated, similar reference numerals may refer to similar elements throughout the application, even if they are shown in different drawings. Unless otherwise stated, the same reference numerals may be used throughout the application text and drawings to refer to the same or substantially the same elements. In one or more aspects, identical elements (or elements with identical names) in different drawings may have the same or substantially the same functions and properties, unless otherwise stated. The names of the respective elements used in the following explanations are chosen for convenience only and may therefore differ from those used in actual products.

[0128] The advantages and features of the disclosure and its implementation methods are clarified by the aspects described with reference to the accompanying drawings. However, the disclosure may be embodied in various forms and should not be interpreted as being limited to the exemplary aspects presented here. Rather, these exemplary aspects are provided to ensure that this disclosure is thorough and complete, assisting those skilled in the art in understanding the inventive concepts without limiting the scope of protection afforded by the disclosure.

[0129] Shapes, dimensions (e.g., sizes, lengths, widths, heights, thicknesses, locations, radii, diameters, and areas), proportions, ratios, angles, numbers, the number of elements, and the like disclosed herein, including those illustrated in the drawings, are merely examples, and thus the disclosure is not limited to the illustrated details. It should be noted, however, that the relative dimensions of the components illustrated in the drawings are part of the disclosure.

[0130] Where a term such as "comprise," "possess," "exhibit," "contain," "form," "made of," "formed of," "composed of," or the like is used in reference to one or more elements (e.g., layers, thin layers, areas, components, sections, elements, parts, regions, surfaces, proportions, steps, operations, and / or the like), one or more further elements may be added, unless "merely" or the like is used. The terms used in the revelation are used only to describe exemplary aspects and are not intended to limit the scope of the revelation. Singular terms may contain plural forms unless the context clearly indicates otherwise.

[0131] The word "exemplary" is used to mean as an example or for illustration, unless otherwise specified. Embodiments are exemplary embodiments. Aspects are exemplary aspects. In one or more implementations, "embodiments," "aspects," "examples," and the like are not to be construed as being preferred or advantageous over other implementations. An aspect, an example, an exemplary aspect, or the like may refer to one or more aspects, one or more examples, one or more exemplary aspects, or the like, unless otherwise specified. Furthermore, the term "may" encompasses all meanings of the term "could."

[0132] Unless explicitly stated otherwise, in one or more aspects, an element, feature, or related information (e.g., a level, extent, dimension, size, or the like) is designed to contain a range of errors or tolerances, even if no explicit description of such an error range or tolerance exists. An error or tolerance range may be caused by various factors (e.g., process factors, internal or external influences, noise, or the like). When interpreting a numerical value, the value is interpreted as containing an error range unless explicitly stated otherwise.

[0133] When describing a positional relationship, if the positional relationship between two parts (e.g., layers, thin layers, areas, components, sections, or the like) is described using terms such as "on," "upon," "above," "below," "below," "near," "close," "adjacent to," "next to," "adjacent to," "on or to one side of," or the like, one or more other parts may be located between the two parts unless a more restrictive term such as "immediately," "directly," or "near" is used.For example, where a structure is described as being positioned "at," "on," "upon," "over," "under," "above," "below," "underneath," "near," "close to," "adjacent to," "next to," "on or to the side of," or the like, of another structure, this description should be interpreted as including both a case in which the structures are touching and a case in which one or more additional structures are positioned between or interposed. Furthermore, the terms "front," "back," "rear," "left," "right," "above," "below," "downward," "upward," "upper," "lower," "up," "down," "column," "row," "vertical," "horizontal," and the like refer to any frame of reference.

[0134] Spatially relative terms such as "under," "below," "lower," "on," "above," "upper," and the like can be used to describe a correlation between different elements (e.g., layers, thin films, areas, components, sections, or the like), as shown in the drawings. These spatially relative terms should be understood as encompassing various orientations of the elements in use or operation, in addition to the orientation shown in the drawings. For example, if the elements shown in the figures were reversed, elements described as "under" or "below" other elements would be oriented "above" them. Thus, the term "under," which is an exemplary term, can encompass all directions of "above" and "under." Likewise, an exemplary term "above" or "on" can encompass both directions of "above" and "under."

[0135] When describing a temporal relationship, if the temporal sequence is described as e.g. 'after', 'subsequent', 'next', 'before', 'preceding', 'before' or the like, a case that is not continuous or non-sequential may be included and thus one or more further events may occur in between, unless a more restrictive term such as 'exactly', 'immediately' or 'directly' is used.

[0136] Terms such as "under," "lower," "above," "upper," and the like can be used here to describe a relationship between one or more elements, as illustrated in the drawings. It is understood that these terms are spatially relative and use the orientation shown in the drawings as their basis.

[0137] It is to be understood that, although the terms "first," "second," or the like may be used here to describe various elements (e.g., layers, thin layers, regions, components, sections, elements, parts, areas, surfaces, proportions, steps, operations, and / or the like), these elements are not intended to be restricted by these terms to any particular order, priority, or number of elements. These terms are used merely to distinguish one element from another. For example, a first element could denote a second element, and vice versa, without altering the scope of the disclosure. Furthermore, the first element, the second element, and the like may be designated arbitrarily for the benefit of those skilled in the art, without altering the scope of the present disclosure.For clarity, the functions or structures of these elements (e.g., the first element, the second element, and so on) are not restricted by ordinal numbers or the names preceding the elements. Furthermore, a first element can contain one or more first elements. Similarly, a second element, or so on, can contain one or more second elements, or so on.

[0138] When describing elements of revelation, the terms “first”, “second”, “A”, “B”, “(a)”, “(b)”, or the like may be used. These terms are intended solely to identify the one or more corresponding elements from among the one or more other elements, and they are not used to define the nature, basis, order, or number of the elements.

[0139] For the expression that an element (e.g., a layer, a thin layer, an area, a component, a section, or the like) is described as being "connected," "coupled," "attached," "glued," or the like to another element, the element can not only be directly connected, coupled, attached, glued, or the like to another element, but can also be indirectly connected, coupled, attached, glued, or the like to another element, with one or more intermediate elements arranged or interposed between the elements, unless otherwise specified.

[0140] For the expression that an element (e.g., a layer, a thin layer, an area, a component, a section, or the like) "touches," "overlaps," or the like with another element, the element may not only directly touch, overlap, or the like with another element or layer, but may also indirectly touch, overlap, or the like with another element or layer, with one or more interposed elements arranged or inserted between the elements, unless otherwise specified.

[0141] The phrase "that an element (e.g., a layer, a thin layer, an area, a component, a section, or the like) is provided for, arranged, connected, coupled, or the like in, on, with, or to another element" can be understood, for example, to mean that at least one section of the element is provided for, arranged, connected, coupled, or the like in, on, with, or to another element, or that the entire element is provided for, arranged, connected, coupled, or the like in, on, with, or to another element. The phrase "that an element (e.g., a layer, a thin layer, an area, a component, a section, or the like) touches, overlaps, or the like in another element can be understood, for example, to mean that...to be understood in such a way that at least one section of the element "touches", "overlaps" or the like at least one section of another element, that the entire element "touches", "overlaps" or the like at least one section of another element, or that at least one section of the element "touches", "overlaps" or the like the entire other element.

[0142] Terms such as "line" or "direction" should not be interpreted solely on the basis of a geometric relationship in which the respective lines or directions are parallel or perpendicular to one another. Such terms can signify a broader range of lines or directions within which the components of the revelation can function appropriately. For example, terms such as "first direction," "second direction," and the like, such as a direction parallel or perpendicular to the "x-axis," "y-axis," or "z-axis," should not be interpreted solely on the basis of a geometric relationship in which the respective directions are parallel or perpendicular to one another, but may be meant to signify directions that exhibit broader directional effects to the extent that the components of the revelation can function appropriately.

[0143] The expression "at least one" should be understood to include all combinations of one or more of the associated listed elements. For example, each of the phrases "at least one of a first element, a second element, or a third element" and "at least one of a first element, a second element, and a third element" can (i) represent a combination of elements created by one or more of the first element, the second element, and the third element, or (ii) represent only one of the first element, the second element, and the third element.

[0144] The expression "a first element, a second element, and / or a third element" should be understood as including any of the first, second, and third elements, as well as all combinations of the first, second, and third elements. For example, A, B, and / or C can include only A; only B; only C; any one of A, B, and C (e.g., A, B, or C); a specific combination of A, B, and C (e.g., A and B; A and C; or B and C); and all of A, B, and C. Furthermore, the expression "A / B" can be understood as A and / or B. For example, the expression "A / B" can refer to only A; only B; A or B; or A and B.

[0145] In one or more aspects, the terms "between" and "under" may be used interchangeably for convenience only, unless otherwise specified. For example, an expression "between several elements" may be understood as "under several elements." In another example, an expression "under several elements" may be understood as "between several elements." In one or more examples, the number of elements may be two. In one or more examples, the number of elements may be greater than two. Furthermore, when an element (e.g., a layer, a thin layer, a region, a component, a section, or the like) is described as "between" at least two elements, the element may be the only element between the at least two elements, or it may also be one or more intervening elements.

[0146] In one or more aspects, the phrases "each other" and "each other" can be used interchangeably for convenience only, unless otherwise indicated. 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 preceding expression can be two or more.

[0147] In one or more aspects, the phrases “one or more among” and “one or more of” may only be used interchangeably for practical purposes, unless otherwise stated.

[0148] The term "or" means "inclusive or" rather than "exclusive or". For example, unless otherwise stated or clear from the context, the expression "using xa or b" means any naturally inclusive permutation. 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".

[0149] Features of different aspects of the disclosure can be partially or fully coupled or combined, technically linked, and operated, connected, or controlled in various ways. Aspects of the disclosure can be implemented or executed independently or jointly in a mutually dependent or interconnected relationship. In one or more aspects, the components of each device can be functionally coupled and configured to represent different aspects of the disclosure.

[0150] Unless otherwise defined, the terms (including technical and scientific terms) used herein have the same meanings as they are normally understood by a person skilled in the art in the field to which exemplary aspects belong. It should also be understood that terms such as those defined in common dictionaries are to be interpreted as having a meaning consistent with, for example, their meaning in the context of the relevant field, and not in an idealized or overly formal sense, unless expressly defined otherwise herein.

[0151] The terms used here have been chosen to be general within the relevant technical field; however, depending on the development and / or change of technology, convention, the preferences of engineers, etc., other terms may exist. Therefore, the terms used here should not be understood as restrictive technical concepts, but rather as examples of terms used to describe exemplary aspects.

[0152] Furthermore, in a specific case, an applicant may choose a term at will, and in that case, its precise meaning will be described here. Therefore, the terms used here should be understood not only on the basis of their names, but also on the basis of their meaning and content.

[0153] “X-axis direction”, “Y-axis direction” and “Z-axis direction” should not be interpreted by a geometric relationship of merely a mutual vertical relationship and may have a broader guideline to the extent that elements of the disclosure can appropriately function.

[0154] The following description details various exemplary aspects of the revelation with reference to the accompanying drawings. Regarding reference symbols to elements in each of the drawings, the same elements may be illustrated in other drawings, and similar reference symbols may refer to similar elements unless otherwise indicated. The same or similar elements may be designated by the same reference symbols even though they are depicted in different drawings.

[0155] Additionally, for the sake of simplicity, the scale, extent, size, and thickness of each of the elements illustrated in the accompanying drawings may differ from an actual scale, extent, size, and thickness, and thus aspects of the disclosure are not limited to a scale, extent, size, and thickness illustrated in the drawings.

[0172] According to one embodiment of the disclosure, the sound device 30 can be arranged on the vehicle interior material 130. The sound device 30 can vibrate the vehicle interior material 130 to generate a sound S based on a vibration of the vehicle interior material 130. For example, the sound device 30 can directly vibrate the vehicle interior material 130 to generate the sound S based on a vibration of the vehicle interior material 130. For example, the sound device 30 can be configured to vibrate the vehicle interior material 130 to output the sound S to the interior section or interior IS of the vehicle 10. Thus, the sound device 30 can use the vehicle interior material 130 as a sound-vibrating plate, a sound membrane, or an acoustic membrane.The vehicle interior material 130 can be a vibration plate, a sound vibration plate, or a sound-generating plate for emitting the sound S. For example, the vehicle interior material 130 can be larger than the sound device 30, but embodiments of the disclosure are not limited to this.

[0173] According to one embodiment of the disclosure, the sound device 30 can be arranged in a dashboard and / or a pillar interior material and / or a floor interior material and / or a roof interior material and / or a door interior material and / or a handle interior material and / or a seat interior material, or can be connected (or coupled) to a trunk interior material and / or a roof console and / or a rearview mirror and / or a glove compartment and / or a sun visor.

[0174] The vehicle 10 or the sound device 30 for vehicles, an embodiment of the disclosure, may include one or more sound devices. The sound device 30 for vehicles may vibrate a corresponding vehicle interior material 130 by means of one or more sound devices 30 arranged in the vehicle interior material 130 in order to emit a realistic sound S and / or a stereo sound containing a multi-channel, to the interior IS of the vehicle 10.

[0175] According to one embodiment of the disclosure, the sound device 30 can be configured in a region between the vehicle interior material 130 and the main structure 110 or in a region between the vehicle interior material 130 and the outer material 120. The sound device 30 can be arranged in a region between the vehicle interior material 130 and the main structure 110 or in a region between the vehicle interior material 130 and the outer material 120 and can indirectly or directly vibrate the region between the vehicle interior material 130 and the main structure 110 and / or the region between the vehicle interior material 130 and the outer material 120 in order to emit a sound.

[0176] According to one embodiment of the disclosure, the sound device 30 can be arranged in an area between the main structure 110 and the outer material 120 and / or an area between the main structure 110 and the vehicle interior material 130 and / or the outer material 120 and / or the vehicle interior material 130. For example, the sound device 30 can be arranged in an area between the main structure 110 and the outer material 120 and / or an area between the main structure 110 and the vehicle interior material 130 and / or the outer material 120 and / or the vehicle interior material 130 and can be configured to emit a sound.For example, the sound device 30 can be arranged in an area between the main structure 110 and the outer material 120 and / or an area between the main structure 110 and the vehicle interior material 130 and / or the outer material 120 and the vehicle interior material 130, and can indirectly or directly vibrate an area between the main structure 110 and the outer material 120 and / or an area between the main structure 110 and the vehicle interior material 130 and / or the outer material 120 and / or the vehicle interior material 130 in order to emit a sound. For example, the sound device 30 can be arranged in the area between the outer material 120 and the vehicle interior material 130 and can indirectly or directly vibrate the outer material 120 and / or the vehicle interior material 130 in order to emit a sound.For example, the sound device 30 can be arranged on the outer material 120 and / or the vehicle interior material 130 and / or in a region between the outer material 120 and the vehicle interior material 130. According to one embodiment of the disclosure, one or more of the outer material 120, the vehicle interior material 130, and a region between the outer material 120 and the vehicle interior material 130 can emit a sound based on a vibration of the sound device 30.

[0177] The sound devices 30, in one embodiment of the present disclosure, can emit sound in a region between the outer material 120 and the interior material 130 of the vehicle 10. For example, the sound devices 30 can be connected to or coupled to the outer material 120 and / or the interior material 130 in a region between the outer material 120 and the interior material 130 and can indirectly or directly cause the outer material 120 and / or the interior material 130 to vibrate in order to emit sound.

[0178] The exterior material 120 and / or the interior material 130 of the vehicle 10 can be a vibration plate, a sound vibration plate, a sound-generating plate, or the like, configured to emit sound. For example, each of the exterior material 120 and the interior material 130 configured to emit sound can be larger than the sound device 30 and can thus function as a large-area vibration plate, a large-area sound vibration plate, or a large-area sound-generating plate, thereby improving the sound characteristic and / or the sound pressure level characteristic of a sound band containing a low-pitched sound band generated by the sound device 30.For example, the frequency of a sound of the low pitch sound band may be 300 Hz or less, 400 Hz or less, or 500 Hz or less, but embodiments of the disclosure are not limited thereto.

[0179] Fig. Figure 2 illustrates a sound device for vehicles as a further embodiment of the disclosure. Fig. Figure 2 illustrates an embodiment implemented by modifying the vehicle interior material on which the sound device, referred to above, is attached. Fig. As described in section 1, the arrangement is as follows. Therefore, repeated descriptions of elements other than a vehicle interior material are omitted or briefly given in the following description.

[0180] With reference to Fig. 2. The sound device 30 can, in another embodiment of the disclosure, vibrate a vehicle interior material 130, which contains one or more materials made of metal, wood, rubber, plastic, carbon, glass, fibers, fabric, paper, a mirror, and leather, in order to emit a sound S. However, embodiments of the disclosure are not limited to this.

[0181] The vehicle interior material 130 of a further embodiment of the present disclosure can comprise a base element 131 and an outer element (or a surface element) 133. For example, the base element 131 can be an injection material, a first interior material, an inner interior material, or a rear interior material; however, embodiments of the disclosure are not limited to these. The outer element 133 can be a second interior material, an outer interior material, a front interior material, an outer surface element, a reinforcing element, or a decorative element; however, embodiments of the disclosure are not limited to these.

[0182] The basic element 131 can contain a plastic material. In one embodiment of the disclosure, the basic element 131 can contain an injection material. For example, the basic element 131 can be an injection material implemented by an injection process using a thermoplastic resin or a thermosetting resin; however, embodiments of the disclosure are not limited to this. The vehicle interior material 130 or the basic element 131 can be configured to cover an interior section of a vehicle 10. For example, the vehicle interior material 130 or the basic element 131 can be configured to cover the main structure 110 and / or the exterior material 120 in an interior IS of the vehicle 10.For example, the vehicle interior material 130 or the basic element 131 may be configured to cover a surface (or an interior surface) of one or more of a main frame, a side frame, a door frame and a handle frame that are exposed in the interior IS of the vehicle 10.

[0183] The basic element 131 can contain a planar section and / or a curved section. For example, the basic element 131 can have a structure that corresponds to a structure (or a back-structure) of a corresponding main structure 110, or it can have a structure that differs from a structure of a corresponding main structure 110.

[0184] The outer element 133 can be arranged on the base element 131. For example, the outer element 133 can be arranged to cover the base element 131. The outer element 133 can cover the base element 131 in the interior section or the interior IS of the vehicle 10 and can be configured to be exposed in the interior section or the interior IS of the vehicle 10. For example, the outer element 133 can be arranged at or coupled to a front surface (or an interior surface) of the base element 131 that is exposed in the interior IS of the vehicle 10.

[0185] The vehicle interior material 130 or the exterior element 133 of an embodiment of the disclosure may contain one or more materials made of plastic, glass, fiber, leather, fabric, rubber, a mirror, wood, paper, carbon, and metal; however, embodiments of the disclosure are not limited to these. For example, the exterior element 133 may be a fiber material. For example, the exterior element 133 containing the fiber material may contain a synthetic fiber and / or a carbon fiber (or an aramid fiber) and / or a natural fiber; however, embodiments of the disclosure are not limited to these. For example, the exterior element 133 containing the fiber material may be a textile web, a knitted web, or a nonwoven fabric; however, embodiments of the disclosure are not limited to these. For example, the exterior element 133 containing the fiber material may be a fabric element; however, embodiments of the disclosure are not limited to these.

[0186] The synthetic fiber can be a thermoplastic resin and can contain a polyolefin-based fiber, which is an environmentally friendly material that releases relatively no harmful substances. For example, the polyolefin-based fiber can contain a polyethylene fiber, a polypropylene fiber, or a polyethylene terephthalate fiber; however, embodiments of the disclosure are not limited to these. The polyolefin-based fiber can be a fiber of a single resin or a fiber of a core-shell structure; however, embodiments of the disclosure are not limited to these. The natural fiber can be a composite fiber of one, two, or more jute fibers, kenaf fibers, abaca fibers, coconut fibers, and wood fibers; however, embodiments of the disclosure are not limited to these.

[0187] The sound device 30 can be covered by the vehicle interior material 130. The sound device 30 can be configured to vibrate the vehicle interior material 130, which contains the base element 131 and the outer element 133, in order to emit a sound S to the inner section and / or the interior IS of the vehicle 10.

[0188] The sound device 30, a further embodiment of the disclosure, can output the sound S to the interior IS of the vehicle 10 using the vehicle interior material 130 as a vibration plate or a sound vibration plate and can output a realistic sound S or a stereo sound containing a multi-channel to the interior IS of the vehicle 10.

[0189] According to a further embodiment of the disclosure, the sound device 30 can be configured to be surrounded by an enclosure. A space can be provided between the sound device 30 and the enclosure, and sound (or a sound pressure level) can be emitted based on a vibration of the vehicle interior material 130 or on the air between the sound device 30 and the enclosure.However, a problem may occur where a sound of the sound band of low pitch is not output, and a problem may occur where the flatness of a sound pressure level is reduced because the number of peaks and dips occurring in a playback frequency band of a sound (or a sound pressure level) generated on the basis of a vibration of the vehicle interior material 130 increases, and each of a highest sound pressure level and a lowest sound pressure level occurring in a playback frequency band of a sound (or a sound pressure level) generated on the basis of a vibration of the vehicle interior material 130 increases.Peaking can be a phenomenon where a sound pressure level at a specific frequency is reflected, while diping can be a phenomenon where a lower sound pressure level is produced because the occurrence of a sound with a specific frequency is reduced. The flatness of a sound characteristic can be the degree of deviation between a highest and a lowest sound pressure level.

[0190] The inventors of the revelation have conducted extensive research and experiments to implement a sound device and a vehicle device containing it, capable of improving the sound characteristics of the low-pitched sound band and the flatness characteristic of a sound pressure level. Based on this extensive research and experimentation, the inventors of the revelation have invented a sound device and a vehicle device containing it, capable of emitting sound that includes both a high-pitched and a low-pitched sound band, and capable of improving the balance characteristic or the flatness characteristic of a sound pressure level. This is described in detail below.

[0191] Fig. Figure 3 illustrates a sound device as an embodiment of the disclosure. Fig. Figure 4 is a perspective exploded view of Fig. 3 of an embodiment of the disclosure.

[0192] With reference to Fig. 3 and Fig. 4. In an embodiment of the disclosure, the sound device 30 may include an enclosure 310 and a sound-generating module 330. The sound device 30 may be configured to vibrate a vehicle interior material 130. For example, the sound device 30 may be a sound-generating device, a sound-emitting device, a loudspeaker device, a vehicle audio device, or an audio device; however, embodiments of the disclosure are not limited to these.

[0193] The sound device 30 can be configured to be connected to (or coupled to) a vehicle structure.

[0226] The opening part 310o can be configured to pass through (or vertically pass through) the first enclosure 311 in a thickness direction Z (or a vertical direction) of the enclosure 310. The opening part 310o can be connected to (or communicate with) the interior 313. For example, the opening part 310o can be connected to (or communicate with) the first chamber 313a. For example, the opening part 310o can be configured to reduce the air pressure of the interior 313 of the enclosure 310. For example, the opening part 310o can be configured to reduce the air pressure of the first chamber 313a. The opening part 310o can be configured to reduce the air pressure of the first chamber 313a of the first enclosure 311 or the air pressure of the first chamber 313a that is provided between the vibration element 331 and the first enclosure 311.Therefore, a section of the low-pitched sound band can expand, thus improving the sound characteristics of the low-pitched sound band. For example, because the pressure (or air pressure) of the first chamber 313a is reduced by the opening part 310o, the amount of displacement (or bending force) of the first vibration device 333, which is arranged between the vibration element 331 and the first enclosure 311, can increase, thus allowing a section of the low-pitched sound band to expand, thereby improving the sound characteristics and / or the sound pressure level characteristics of the low-pitched sound band. Similarly, the sound characteristics (or sound pressure level) of the low-pitched sound band generated on the basis of vibration of the first vibration device 333 and / or the second vibration device 335 can be improved.

[0227] According to one embodiment of the disclosure, the opening part 310o can be arranged such that it corresponds to a central section of the sound-generating module 330.

For example, the interior 313 of the enclosure 310 can contain the first space 313a, which is connected to the opening part 310o.

For example, the opening part 310o can include a linear shape having a size (or length) smaller than the first vibration device 333 located at the vibration element 331. For example, the opening part 310o can be a hole, a recess, or a slot, but embodiments of the disclosure are not limited to these. For example, the opening part 310o can be a sound emission section, a first sound emission opening, a sound output section, a sound output opening, a sound output hole, or a vent hole, but embodiments of the disclosure are not limited to these.

[0229] The opening 310o can be a space in which a sound wave, generated on the basis of a vibration of the sound generation module 330, propagates (or is transmitted) to the interior IS of the vehicle 10. For example, a vibration of the sound generation module 330 can be transmitted through the opening 310o to the interior IS of the vehicle 10. Similarly, a sound wave (or sound) based on the vibration of the sound generation module 330 can be transmitted (or emitted or radiated) through the opening 310o to the interior IS of the vehicle 10. Accordingly, the amplitude (or displacement) of the vibration element 331 can increase based on the vibration of the sound generation module 330, thus improving the sound characteristic and / or sound pressure level characteristic generated on the basis of a vibration of the vibration element 331.

[0230] The first enclosure 311, which contains the opening part 310o, can be arranged closer to the vehicle interior material 130 than the second enclosure 312. For example, the first enclosure 311, which contains the opening part 310o, can be arranged closer to the vehicle interior material 130 than the second enclosure 312. Accordingly, a sound generated on the basis of vibrations from one or more of the first vibration device 333 and the second vibration device 335 can be emitted to the interior IS of the vehicle 10, and thus a sound containing the sound band of low pitch can be emitted to the interior IS of the vehicle 10.

[0231] The first enclosure 311 can include a tilted surface (or inclined surface) 311s and an inner surface 311i. The tilted surface 311s can be configured to be inclined between the opening part 310o and the inner surface 311i of the first enclosure 311. The tilted surface 311s can be configured to direct sound generated based on a vibration of the sound generation module 330 to the interior IS of the vehicle 10. Accordingly, the sound generated based on the vibration of the sound generation module 330 can be emitted to the interior IS of the vehicle 10, and the sound characteristic and / or sound pressure level characteristic of a sound containing the low-pitched sound band can be further enhanced.For example, the tilting surface 311s can be a guide surface or a sound guide surface, but embodiments of the disclosure are not limited thereto.

The connecting element 380 can be configured between the first enclosure 311 and the vehicle interior material 130. For example, the first enclosure 311 can include an inner surface 311i and an outer surface. The inner surface 311i of the first enclosure 311 can face a vibration element 331. The outer surface of the first enclosure 311 can be a surface that is opposite the inner surface 311i of the first enclosure 311. For example, the connecting element 380 can be connected to the outer surface of the first enclosure 311. The connecting element 380 can be a coupling element, an intermediate element, a buffer element, or a connection surface element; however, embodiments of the disclosure are not limited to these.

[0409] The connecting element 380 can contain a material that differs from that of the first coupling element 321 and / or the second coupling element 322. For example, the connecting element 380 can contain a material that exhibits an adhesive force that differs from that of the first coupling element 321 and / or the second coupling element 322. Because the connecting element 380 contains a material that exhibits an adhesive force that differs from that of the first coupling element 321 and / or the second coupling element 322, a separation or loosening process (or a rework) of the connecting element 380 from the vehicle interior material 130 can be easily carried out in a separation or loosening process (or a rework) of the sound device 30 attached to the vehicle interior material 130.Accordingly, a process of attaching or mounting the sound device 30 to the vehicle interior material 130 or a process of separating or attaching / removing the sound device 30 from the vehicle interior element 130 can be easily carried out.

[0410] The connecting element 380 can be coupled to (or attached to) the rear surface of the enclosure 310 and can touch (or make surface contact with) a first surface 130s1 of the vehicle interior material 130; however, embodiments of the disclosure are not limited thereto. For example, in a case where the connecting element 380 is coupled to (or attached to) the rear surface of the enclosure 310 and simply touches (or makes surface contact with) the first surface 130s1 of the vehicle interior material 130, a process of separating or detaching (or reworking) the connecting element 380 from the vehicle interior material 130 without damaging the sound device 30 or the vehicle interior material 130 can be easily carried out in a process of separating and detaching (or reworking) the sound device 30 from the vehicle interior material 130.

For example, the connecting element 380 may comprise rubber; however, embodiments of the disclosure are not limited thereto. For example, the rubber may be ethylene propylene diene rubber (or M-class ethylene propylene diene rubber), ethylene propylene rubber, or urethane rubber; however, embodiments of the disclosure are not limited thereto.For example, the ethylene propylene rubber can be ethylene propylene diene monomer (EPDM), but embodiments of the disclosure are not limited to this. For example, the hardness of the EPDM can be in the range of 40 to 90, but embodiments of the disclosure are not limited to this. For example, the tensile strength of the EPDM can be in the range of 50 kg / cm. 2 up to 200 kg / cm² 2However, embodiments of the disclosure are not limited to these. For example, the connecting element 380 can contain a highly elastic rubber or a low-elastic rubber, but embodiments of the disclosure are not limited to these. According to one embodiment of the disclosure, because the connecting element 380 contains rubber or the like, when a vibration of the enclosure 310 or the first enclosure 311 is transmitted to the vehicle interior material 130, the loss of vibration can be prevented or minimized, and thus the sound characteristics and / or the sound pressure level characteristics of a low-pitched sound band can be further improved.

[0412] According to one embodiment of the disclosure, the first coupling element 321 and the second coupling element 322 of the coupling element 320 may include an adhesive, a double-sided adhesive tape, a double-sided adhesive tape, a double-sided foam tape, a double-sided adhesive foam tape, a double-sided cushion, a double-sided foam cushion, a double-sided adhesive foam cushion, a double-sided cushion element, a double-sided cushioning element, a double-sided cushioning cushion or a double-sided cushioning tape or the like, however, embodiments of the disclosure are not limited thereto.

[0413] According to one embodiment of the disclosure, the connecting element 380 may contain a material that differs from that of the first adhesive element 332 and / or the second adhesive element 334.

For example, the connecting element 380 may further include a hole 380o that is connected to the opening part 310o in the enclosure 310 or the first enclosure 311.

[0415] The hole 380o can be arranged such that it corresponds to (or overlaps) the opening part 310o. The hole 380o can have the same shape as the opening part 310o, but embodiments of the disclosure are not limited to this. For example, the hole 380o can have the same shape as the opening part 310o and can be larger than the opening part 310o. Accordingly, sound based on a vibration of the sound-generating module 330 can be emitted to an interior IS of a vehicle through (or via) the opening part 310o and the hole 380o. For example, the hole 380o can be an opening part, an opening hole, a slot, a recess, a connecting hole, or an intermediate hole, but embodiments of the disclosure are not limited to this.

The hole 380o of the connecting element 380 can be the same size as the opening part 310o and the hole 135 respectively, or it can be larger than the opening part 310o and the hole 135 respectively.Accordingly, sound based on a vibration of the sound generation module 330 can be emitted to an interior IS of a vehicle through (or via) the opening part 310o, the hole 380o and the hole 135.

[0417] With reference to Fig. 25A and Fig. According to 25B, the coupling part 500 can be connected to or coupled to the sound device 30 through the second hole 135 of the vehicle interior material 130, the hole 380o of the connecting element 380, and the opening part 310o of the first enclosure 311 (one direction of arrow). For example, the coupling part 500 can be connected to or coupled to the opening part 310o of the first enclosure 311 in the interior of the vehicle through the second hole 135 of the vehicle interior material 130 and the hole 380o of the connecting element 380.

For example, the hook element 504 of the coupling part 500 can be connected to or coupled to the opening part 310o of the first enclosure 311. For example, the hook element 504 of the coupling part 500 can be inserted (or received) into the opening part 310o of the first enclosure 311 and can be connected to or coupled to an inclined surface 311s of the first enclosure 311 by a hook coupling arrangement.

[0418] Fig. 25C illustrates a sound device of another embodiment of the disclosure.

[0419] With reference to Fig. In another embodiment of the disclosure, the vehicle interior material 130 may include one or more curved (or flexible) sections 136. The connecting element 380 may be configured to correspond to the one or more curved sections 136. The connecting element 380 may contact the one or more curved sections 136.

The one or more holes 331o can be configured to pass through the vibration element 331 in a thickness direction Z of the vibration element 331. For example, the one or more holes 331o can be formed to pass through the vibration element 331 vertically in a thickness direction Z of the vibration element 331.

[0426] A sound-generating module 330, an embodiment of the disclosure, may include the vibration element 331, which contains the one or more holes 331o, and vibration devices 333 and 335 configured at the vibration element 331.

[0427] The one or more holes 331o can be configured to regulate an airflow in an interior space 313 of the enclosure 310. For example, the one or more holes 331o can perform a control such that air flows in the interior spaces 313 of the enclosure 310, which are spatially separated from one another by the vibration element 331. For example, the one or more holes 331o can be configured to regulate an airflow between a first space 313a and a second space 313b, which are spatially separated from one another by the vibration element 331 in the interior space 313 of the enclosure 310. For example, the one or more holes 331o can be a first hole, a vent hole, an airflow hole, a ventilation hole, a shaft hole, a first connecting hole, a first communication hole, or a first space connecting part; however, embodiments of the disclosure are not limited to these.

For example, the one or more holes 331o can be configured to connect the first chamber 313a and the second chamber 313b, which are spatially separated from each other by the vibration element 331 in the interior 313 of the enclosure 310. For example, the first chamber 313a and the second chamber 313b of the interior 313 in the enclosure 310 can be connected to each other (or establish a connection) by the one or more holes 331o. For example, the one or more holes 331o can be configured to reduce the air pressure of the first chamber 313a of the first enclosure 311 or of the first chamber 313a provided between the vibration element 331 and the first enclosure 311.Accordingly, a band (a playback band) of a low-pitched sound band can be extended, thereby improving the sound characteristics and / or the sound pressure level characteristics of the low-pitched sound band. Furthermore, the sound generation module 330 can be set into more stable vibration by the one or more holes 331o in the vibration element 331, thus further improving the sound characteristics and / or the sound pressure level characteristics.

[0430] According to one embodiment of the disclosure, the interior space 313 can be located between a first surface of the sound-generating module 330 and the first enclosure 311 and can be connected to the opening part 310o.

The enclosure 311 can contain the second space 313b between the second enclosure 312 and a second surface of the sound-generating module 330 that is opposite the first surface. The interior space 313 and the second space 313b can be connected to each other (or establish a connection with it) through one or more holes 331o.

[0431] According to one embodiment of the disclosure, the one or more holes 331o can be arranged adjacent to the vibration devices 333 and 335. For example, the one or more holes 331o can be arranged on a circumference of each of the vibration devices 333 and 335. For example, the one or more holes 331o can be arranged adjacent to a side surface of each of the vibration devices 333 and 335. For example, the distance between the one or more holes 331o and each of the vibration devices 333 and 335 can be less than the distance between the one or more holes 331o and a side wall (or a side surface) of the enclosure 310.For example, if one or more holes 331o are arranged in a position that is further away from each of the vibration devices 333 and 335, the sound characteristic and / or the sound pressure level characteristic of a low-pitched sound band can be further improved.

[0432] According to one embodiment of the disclosure, the one or more holes 331o can be configured in the vibration element 331 adjacent to the vibration devices 333 and 335, with the vibration devices 333 and 335 intersected. For example, the vibration element 331 can include a first circumferential region adjacent to a first side surface of each of the vibration devices 333 and 335, and a second circumferential region opposite a second side of each of the vibration devices 333 and 335. For example, with respect to a first direction X, the vibration element 331 can include the first circumferential region, a vibration region, and the second circumferential region.For example, in the vibration element 331, each of the first and second circumferential regions can be a hole region or a non-arrangement region of each of the vibration devices 333 and 335, and the vibration region can be a configuration region (or an arrangement region) of the vibration devices 333 and 335. For example, the one or more holes 331o in each of the first circumferential region and the second circumferential region of the vibration element 331 can be configured 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 vibration devices 333 and 335.

[0433] According to one embodiment of the disclosure, the vibration devices 333 and 335 can each have a long side and a short side. A distance (or a separation distance or a shortest distance) between the one or more holes 331o and the short side of the vibration devices 333 and 335 can represent a ratio of the length of a short side of the vibration devices 333 and 335. According to one embodiment of the disclosure, a distance between the one or more holes 331o and the vibration devices 333 and 335 can be 60% or less of the length of the short side of the vibration devices 333 and 335.

[0434] With reference to Fig. 26 and Fig. 27. The one or more holes 331o can be arranged closer to the vibration devices 333 and 335 than a coupling element 320. The coupling element 320 can include a first coupling element 321 and a second coupling element 322. For example, the one or more holes 331o can be arranged closer to the vibration devices 333 and 335 than the first coupling element 321 and the second coupling element 322. Accordingly, a sound characteristic and / or a sound pressure level characteristic of a low-pitched sound band can be improved. A sound output characteristic based on a distance between the vibration devices 333 and 335 and the one or more holes 331o is described below with reference to Fig. 46A and Fig. 46A described.

[0435] According to one embodiment of the disclosure, the one or more holes 331o need not overlap with an opening part 310o. For example, the one or more holes 331o can be arranged such that they are spaced apart from the opening part 310o. Accordingly, a sound generated on the basis of a vibration (or actuation) of each of the vibration devices 333 and 335 in the second chamber 313b can be emitted through the one or more holes 331o to the first chamber 313a, and a sound characteristic and / or a sound pressure level characteristic of a low-pitched sound band can be improved.

[0436] With reference to Fig. 26 and Fig. 28 can be a size of one or more holes 331o differing from that of one or more holes 331o which are in Fig. Figure 27 illustrates the differences. If the size of one or more holes 331o increases, the sound characteristic and / or the sound pressure level characteristic of a low-pitched sound band may be improved. For example, the distance between one or more holes 331o and the vibration devices 333 and 335 may be less than the distance between one or more holes 331o and a side wall (or a side surface) of the enclosure 310. For example, if the size of one or more holes 331o increases, the sound pressure level characteristic of a low-pitched sound band of 400 Hz or less may be further improved. A sound output characteristic based on the size of one or more holes 331o is described below with reference to Fig. 45A, Fig. 45B and Fig. 47 described.

[0437] With reference to Fig. 26 and Fig. 29 The one or more holes 331o can be configured with two holes 331o. For example, the sound device 30 of an embodiment of the present disclosure can further include two holes 331o. The two holes 331o can be configured adjacent to each other. For example, the two holes 331o can be configured adjacent to the vibration devices 333 and 335. For example, the distances between each of the two holes 331o and the vibration devices 333 and 335 can be different. For example, the two holes 331o can be configured parallel in a first direction X to be adjacent to the vibration devices 333 and 335. For example, the distances between each of the two holes 331o and the vibration devices 333 and 335 can be equal to each other. For example, each of the two holes 331o can be configured adjacent to the vibration devices 333 and 335.For example, the two holes 331o can be configured parallel in a second direction Y to be adjacent to the vibration devices 333 and 335.

[0438] Each of the two holes 331o in an embodiment of the disclosure can be configured in a polygon shape such as a circular shape, an oval shape or a square shape, however embodiments of the disclosure are not limited thereto.

[0439] With reference to Fig. 26 and Fig. The one or more holes 331o can be configured in a square shape. For example, the one or more holes 331o can be configured adjacent to the vibration devices 333 and 335. A sound output characteristic based on the shape of the one or more holes 331o is described below with reference to Fig. 48 described.

[0440] With reference to Fig. 27- Fig. 30 One or more of the holes 331o can have a hole wall that is straight or vertical, such that any of the polygonal shapes have a constant cross-sectional shape. For example, if the one or more holes 331o have a circular shape, then the one or more holes 331o can have a cylindrical shape in cross-section; however, embodiments of the disclosure are not limited thereto. For example, the hole wall can have a shape that varies inwardly from an upper (or first) opening to a lower (or second) opening of the one or more holes. In various embodiments of the disclosure, the top opening can refer to an opening of the hole 331o facing the second enclosure 312, and the bottom opening can refer to an opening of the hole 331o facing the first enclosure 311.

[0441] In embodiments of the disclosure, the shape of the perforated wall can become narrower from the top opening to the bottom opening, or narrower from the bottom opening to the top opening. In various embodiments of the disclosure, the size or area of ​​the top opening and the bottom opening can be different, but they can also be the same. If they are different, the top opening can be smaller than the bottom opening, or vice versa.

[0442] In various embodiments of the disclosure, the shapes (or the width or the diameters) of the hole wall can be widest at the upper and lower openings and gradually decrease in size towards the center of the hole 331o, or they can be widest at the center and gradually decrease in size towards the upper and lower openings. The change in the width of the hole wall need not be gradual, and one or more steps or curves can be present in the hole wall within the hole 331o. In various embodiments of the disclosure, the cross-sectional shape of the hole wall can be, but is not limited to, triangular waves or curved waves, concave shapes or convex shapes. Furthermore, if there are several holes 331o, the cross-sectional shapes of the hole walls can be the same or different from one another.

[0443] Additionally, the second enclosure 312 can contain a hole similar to that of the opening section 310o of the first enclosure 311.

[0444] According to one embodiment of the disclosure, the one or more holes 331o can emit a sound (or a rearward sound) which is generated on the basis of a vibration of each of the vibration devices 333 and 335 and is emitted to a rear surface (or rearward direction) of the vibration element 331 through the opening part 310o of the first enclosure 311.Therefore, sound generated on the basis of a vibration (or actuation) of each of the vibration devices 333 and 335 at a rear surface of the vibration element 331 or the second chamber 313b of the enclosure 310 can be emitted to the first chamber 313a through the one or more holes 331o and can be emitted (or radiated) through the opening part 310o of the first enclosure 311 and a hollow part 501 of a coupling part 500, thus further improving the sound characteristic and / or the sound pressure level characteristic of a low-pitched sound band. According to one embodiment of the disclosure, the sound characteristic and / or the sound pressure level characteristic of a low-pitched sound band, e.g., 400 Hz or less, can be further improved.

[0445] Fig. Figure 31 illustrates a sound device of another embodiment of the disclosure. Fig. Figure 31 illustrates an embodiment which is achieved by modifying the enclosure of the sound device 30, which is described above with reference to Fig. 1 to Fig. The implementation is as described in section 30. Therefore, the following description precisely describes the enclosure, and the other elements are identified by the same reference symbols as in section 30. Fig. 1 to Fig. 30 are designated and their repeated descriptions are omitted or given briefly.

[0446] With reference to Fig. In the sound device, a further embodiment of the disclosure may include the enclosure 310 and a first enclosure 311. For example, the second enclosure 312 may be contained within the enclosure 310 described above with reference to Fig. 1 to Fig. As described in 26, it may be removed (or omitted) and thus the enclosure 310 can only be configured with the first enclosure 311.

[0447] The enclosure 310 or the first enclosure 311 can be connected to a sound-generating module 330 with an interior space 313 in between. The enclosure 310 or the first enclosure 311 can be connected to a rear circumferential section of a vibration element 331 with the interior space 313 in between.

[0448] According to a further embodiment of the disclosure, the vibration element 331 can be configured to cover the interior 313 of the first enclosure 311. For example, the vibration element 331 can be configured to cover a section of the interior 313 of the first enclosure 311. The vibration element 331 can be configured to cover the first space 313a of the first enclosure 311. For example, the vibration element 331 can be configured to cover a section of the first space 313a of the first enclosure 311.

[0449] In a case where the enclosure 310 is configured with the first enclosure 311, the sound characteristic and / or the sound pressure level characteristic of a sound device 30 can be improved further than in a case where the enclosure 310 is configured with the first enclosure 311 and the second enclosure 312. For example, in a case where the enclosure 310 is configured with the first enclosure 311, the sound characteristic and / or the sound pressure level characteristic of a mid / low pitch sound band, e.g., 2 kHz or less, can be further improved, and a sound reproduction band can be extended further.

[0451] The connecting element 380, in another embodiment of the disclosure, can be configured between the first enclosure 311 and the vehicle interior material 130. For example, the first enclosure 311 can include an inner surface 311i and an outer surface. The inner surface 311i of the first enclosure 311 can face a vibration element 331. The outer surface of the first enclosure 311 can be a surface that is opposite the inner surface 311i of the first enclosure 311. For example, the connecting element 380 can be connected to the outer surface of the first enclosure 311.

[0452] The sound device 30, in a further embodiment of the disclosure, may further comprise a first coupling element 321 and a second coupling element 322. The first coupling element 321 may be located between the vibration element 331 and the first enclosure 311. A description of the first coupling element 321 may be essentially the same as the description of Fig. 3 and Fig. 4, and thus similar reference symbols refer to similar elements, and repeated descriptions are omitted or briefly given below.

[0454] According to a further embodiment of the disclosure, because the connecting element 380 contains a material that has an adhesive force different from that of the first coupling element 321, a separation or detachment process (or a rework) of the connecting element 380 from the vehicle interior material 130 can be easily carried out in a separation or detachment process (or a rework) of the sound device 30 attached to the vehicle interior material 130. Similarly, a process of attaching or mounting the sound device 30 to the vehicle interior material 130, or a process of separating or attaching / detaching the sound device 30 from the vehicle interior material 130, can be easily carried out.

[0455] According to a further embodiment of the disclosure, each of the connecting element 380 and the first coupling element 321 can be essentially the same as in the descriptions above of Fig. 25A to Fig. 25C, and thus similar reference symbols refer to similar elements, and their repeated descriptions are omitted or given briefly.

[0456] According to a further embodiment of the disclosure, because the sound device 30 includes the first enclosure 311 and the connecting element 380, a sound characteristic and / or a sound pressure level characteristic of each of a low-pitched sound band and a medium-pitched sound band can be further improved, a sound reproduction band can be extended, and a fastening or loosening process of the sound generation module 330, which is attached to the vehicle interior material 130, can be easily carried out.

[0460] The sound device 30, in a further embodiment of the disclosure, may further comprise a coupling element 320 or a first coupling element 321. The first coupling element 321 may be located between the vibration element 331 and the first enclosure 311.

For example, the connecting element 380 can contain a material that has high elasticity (or a high modulus of elasticity). For example, the connecting element 380 can contain a material that has an adhesive force that differs from that of the first coupling element 321.Because the connecting element 380 contains a material that exhibits an adhesive force different from that of the first coupling element 321, a separation or detachment process (or a rework) of the connecting element 380 from the vehicle interior material 130 can be easily carried out in a separation or detachment process (or a rework) of the sound device 30 attached to the vehicle interior material 130. Similarly, a process of attaching or mounting the sound device 30 to the vehicle interior material 130, or a process of separating or attaching / detaching the sound device 30 from the vehicle interior material 130, can be easily carried out.

[0463] According to a further embodiment of the disclosure, each of the connecting element 380 and the first coupling element 321 can be essentially the same as in the descriptions above of Fig. 25A to Fig. 25C, and thus similar reference symbols refer to similar elements, and their repeated descriptions are omitted or given briefly.

[0464] According to a further embodiment of the disclosure, because the sound device 30 includes the first enclosure 311 and the connecting element 380, a sound characteristic and / or a sound pressure level characteristic of each of a low-pitched sound band and a medium-pitched sound band can be further improved, a sound reproduction band can be extended, and a fastening or loosening process of the sound generation module 330, which is attached to the vehicle interior material 130, can be easily carried out.

For example, the second partial enclosure 312 can include a vertical side wall but may lack a horizontal top surface, such that the vertical side wall of the second partial enclosure 312 projects from the sound-generating module 330. In further embodiments of the disclosure, the second partial enclosure 312 can have the vertical side wall and a horizontal extension connected to the vertical side wall, such that the second partial enclosure 312 partially exposes the sound-generating module 330. The presence of the second partial enclosure 312 can protect the sound-generating module 330 while still leaving the module exposed.In various embodiments of the disclosure, the second partial enclosure 312 can contain a hole similar to that of the opening section 310o of the first enclosure 311. The location of the hole in the second partial enclosure 312 can be at the horizontal extension or the vertical side wall.

[0469] The vibration generator 1310 can contain a piezoelectric material exhibiting piezoelectric properties. The vibration generator 1310 can cause a vibration element (or vehicle interior material) to vibrate (or displace or drive) based on a vibration (or displacement or actuation) of the piezoelectric material applied to it by an electrical signal (or speech signal or sound signal). For example, the vibration generator 1310 can alternately contract and / or expand due to a piezoelectric effect (or property) to induce vibration (or displacement or actuation).For example, the vibration generator 1310 can be set into vibration (or displaced or driven) in a vertical direction (or a thickness direction) Z, while contraction and / or expansion are alternately repeated by an inverse piezoelectric effect. For example, in the vibration generator 1310, the piezoelectric material containing a piezoelectric ceramic can be set into vibration or mechanically displaced (or set into vibration or driven) in response to an externally applied electrical signal.

For example, the piezoelectric material can have a property such that when a pressure or twisting phenomenon is exerted on a crystal structure by an external force, a potential difference arises due to dielectric polarization caused by a change in the relative position of a positive (+) ion and a negative (-) ion, thus generating a vibration through an electric field based on a blocking voltage applied to it.For example, the vibration element 1311a may be a piezoelectric layer, a layer of a piezoelectric material, an electroactive layer, a piezoelectric composite layer, a piezoelectric composite material, a piezoelectric ceramic composite material, or the like, but embodiments of the disclosure are not limited thereto.

The second electrode part 1311c can be the same size as the vibrating part 1311a or it can be smaller. For example, the second electrode part 1311c can have the same shape as the vibrating part 1311a, but embodiments of the disclosure are not limited to this.

[0479] According to one embodiment of the disclosure, in order to prevent an electrical short circuit between the first electrode part 1311b and the second electrode part 1311c, each of the first electrode part 1311b and the second electrode part 1311c can be formed on a remaining section except a circumferential section of the vibrating part 1311a. For example, the first electrode part 1311b can be formed on an entire remaining section except a circumferential section of the first surface 1311s1 of the vibrating part 1311a. For example, the second electrode part 1311c can be formed on an entire remaining section except a circumferential section of the second surface 1311s2 of the vibrating part 1311a.For example, the distance between a side surface (or a side wall) of each of the first electrode part 1311b and the second electrode part 1311c and a side surface (or a side wall) of the vibrating part 1311a can be at least 0.5 mm or more. For example, the distance between the side surface of each of the first electrode part 1311b and the second electrode part 1311c and the side surface of the vibrating part 1311a can be at least 1 mm or more, but embodiments of the disclosure are not limited thereto.

The opaque conductor material may contain gold (Au), silver (Ag), platinum (Pt), palladium (Pd), molybdenum (Mo), magnesium (Mg), carbon, or silver (Ag) containing a glass frit or the like, or may be made from an alloy thereof, but embodiments of the disclosure are not limited thereto.For example, to improve an electrical property and / or a vibration characteristic of the vibration part 1311a, each of the first electrode part 1311b and the second electrode part 1311c may contain silver (Ag), which has a low resistivity. For example, the carbon may contain carbon black and / or carbon black and / or carbon nanotubes and / or a carbon material containing graphite; however, embodiments of the disclosure are not limited thereto.

[0481] The oscillating element 1311a can be polarized (or polarized) by a specific voltage applied to the first electrode element 1311b and the second electrode element 1311c in an atmosphere of a specific temperature or an atmosphere of temperature that can be changed from a high temperature to room temperature; however, embodiments of the disclosure are not limited thereto.

For example, the polarization direction (or the polarization direction) formed in the oscillating element 1311a can be formed or aligned (or arranged) from the second electrode element 1311c to the first electrode element 1311b.

[0482] The vibrating element 1311a can contract and / or expand alternately and repeatedly by means of an inverse piezoelectric effect based on a drive signal applied externally to the first electrode element 1311b and the second electrode element 1311c to set it into vibration. For example, the vibrating element 1311a can be set into vibration in a vertical (or thickness) direction and in a planar direction by the signal applied to the first electrode element 1311b and the second electrode element 1311c. The vibrating element 1311a can be displaced (or set into vibration or driven) by contraction and / or expansion in the planar direction, thereby improving a vibration characteristic that includes a sound characteristic and / or a sound pressure level characteristic of the vibration generator 1310.

For example, the first cover element 1313 can be located at the first electrode part 1311b. For example, the first cover element 1313 can be configured to be larger than the vibration generating part 1311. The first cover element 1313 can be configured to protect the first surface of both the vibration generating part 1311 and the first electrode part 1311b.

[0485] The second cover element 1315 can be arranged on a second surface of the vibration generating part 1311. For example, the second cover element 1315 can be configured to cover the second electrode part 1311c of the vibration generating part 1311. For example, the second cover element 1315 can be located within the second electrode part 1311c. For example, the second cover element 1315 can be configured to be larger than the vibration generating part 1311 and can be configured to be the same size as the first cover element 1313. The second cover element 1315 can be configured to protect the second surface of the vibration generating part 1311 and the second electrode part 1311c.

[0486] The first cover element 1313 and the second cover element 1315 of an embodiment of the disclosure may contain the same material or different materials. For example, each of the first cover element 1313 and the second cover element 1315 may be a thin polyimide layer (PI layer), a thin polyethylene terephthalate layer (PET layer), or a thin polyethylene naphthalate layer (PEN layer), but embodiments of the disclosure are not limited thereto.

[0487] The first cover element 1313 can be connected to or coupled to the first surface of the vibration-generating part 1311 or the first electrode part 1311b by means of a first adhesive layer 1317. For example, the first cover element 1313 can be connected to or coupled to the first surface of the vibration-generating part 1311 or the first electrode part 1311b by a thin-film lamination process using the first adhesive layer 1317.

[0488] The second cover element 1315 can be connected to or coupled to the second surface of the vibration-generating part 1311 or the second electrode part 1311c by means of a second adhesive layer 1319. For example, the second cover element 1315 can be connected to or coupled to the second surface of the vibration-generating part 1311 or the second electrode part 1311c by a thin-film lamination process using the second adhesive layer 1319.

[0489] Each of the first adhesive layer 1317 and the second adhesive layer 1319 in an embodiment of the disclosure may contain an electrically insulating material that exhibits adhesive properties and is capable of compression and decompression. For example, each of the first adhesive layer 1317 and the second adhesive layer 1319 may contain an epoxy resin, an acrylic resin, a silicone resin, a urethane resin, an acrylic-based polymer, or a urethane-based polymer; however, embodiments of the disclosure are not limited thereto.

[0490] The first adhesive layer 1317 and the second adhesive layer 1319 can be configured between the first cover element 1313 and the second cover element 1315 to surround the vibration-generating part 1311. For example, the first adhesive layer 1317 and / or the second adhesive layer 1319 can be configured to partially or completely surround the vibration-generating part 1311.

[0491] One of the first cover element 1313 and the second cover element 1315 can be connected to the vibration element 331 by the adhesive element 332 and 334, which is in Fig. 3 to Fig. 32 is illustrated, connected or coupled to it.

[0492] The vibration generator 1310, an embodiment of the disclosure, may further include a signal input element 1320.

[0493] The signal input element 1320 can be configured to supply the control signal, which is supplied by a control circuit part, to the vibration generation part 1311. The signal input element 1320 can be configured to be electrically connected to the vibration part 1311a. The signal input element 1320 can be configured to be electrically connected to the first electrode part 1311b and the second electrode part 1311c of the vibration generation part 1311.

[0494] A section of the signal input element 1320 can be received (or inserted) between the first cover element 1313 and the second cover element 1315. An end section (or remote end section or side) of the signal input element 1320 can be arranged or inserted (or received) between an edge section (or circumferential section) of the first cover element 1313 and an edge section (or circumferential section) of the second cover element 1315. One edge section of the first cover element 1313 and one edge section of the second cover element 1315 can receive or vertically (or upward / downward) the end section (or remote end section or one side) of the signal input element 1320. Accordingly, the signal input element 1320 can be integrated (or configured) as a single body with the vibration-generating part 1311.Accordingly, the sound generation module 330 or the vibration device 333 and 335 can be implemented (or configured) in a type of thin film integrated with the signal input element 1320. For example, the signal input element 1320 can be configured as a part (or component) with the vibration generation part 1311, thereby achieving a unimaterialization effect. For example, the signal input element 1320 can be configured as a signal cable, a flexible cable, a flexible printed circuit cable, a flexible flat cable, a single-sided flexible printed circuit, a single-sided flexible printed circuit board, a flexible multilayer printed circuit, or a flexible multilayer printed circuit board; however, embodiments of the disclosure are not limited thereto.

[0495] The signal input element 1320, in one embodiment of the disclosure, can comprise a basic element 1321 and several signal lines 1323a and 1323b. For example, the signal input element 1320 can comprise a basic element 1321, a first signal line 1323a, and a second signal line 1323b.

[0496] The basic element 1321 can contain a transparent or an opaque plastic material; however, embodiments of the disclosure are not limited thereto. The basic element 1321 can have a certain width in a first direction X and can be longitudinally extended in a second direction Y that intersects the first direction X.

[0497] The first signal line 1323a and the second signal line 1323b can be arranged parallel to the second direction Y on the first surface of the base element 1321 and can be spaced apart or electrically separated from each other in the first direction X. The first signal line 1323a and the second signal line 1323b can also be arranged parallel to each other on the first surface of the base element 1321. For example, the first signal line 1323a and the second signal line 1323b can be implemented in a line configuration by patterning a metal layer (or a conductive layer) formed or deposited on the first surface of the base element 1321.

[0498] End sections (or remote end sections or certain sides) of the first signal line 1323a and the second signal line 1323b may be separate from each other and may therefore be individually curved or bent.

[0499] The end section (or remote end section or one side) of the first signal line 1323a can be electrically connected to the first electrode part 1311b of the vibration generating part 1311. For example, the end section of the first signal line 1323a can be electrically connected to at least one section of the first electrode part 1311b of the vibration generating part 1311 in one edge section of the first cover element 1313. For example, the end section (or remote end section or one side) of the first signal line 1323a can be electrically and directly connected to at least one section of the first electrode part 1311b of the vibration generating part 1311. For example, the end section (or remote end section or one side) of the first signal line 1323a can be electrically connected to or directly touching the first electrode part 1311b of the vibration generating part 1311.For example, the end section of the first signal line 1323a can be electrically connected to the first electrode part 1311b by a conductive double-sided adhesive tape. Accordingly, the first signal line 1323a can be configured to transmit a first control signal, supplied by a control circuit part (or a vibration driver), to the first electrode part 1311b of the vibration generating part 1311.

[0500] The end section (or the remote end section or one side) of the second signal line 1323b can be electrically connected to the second electrode part 1311c of the vibration generating part 1311. For example, the end section of the second signal line 1323b can be electrically connected to at least one section of the second electrode part 1311c of the vibration generating part 1311 in one edge section of the second cover element 1315. For example, the end section of the second signal line 1323b can be electrically and directly connected to at least one section of the second electrode part 1311c of the vibration generating part 1311. For example, the end section of the second signal line 1323b can be electrically connected to or directly touching the second electrode part 1311c of the vibration generating part 1311.For example, the end section of the second signal line 1323b can be electrically connected to the second electrode part 1311c by means of conductive double-sided adhesive tape. Accordingly, the second signal line 1323b can be configured to transmit a second control signal, supplied by the control circuit part (or the vibration driver), to the second electrode part 1311c of the vibration generating part 1311.

[0501] The signal input element 1320, an embodiment of the disclosure, may further include an insulating layer 1325.

[0502] The insulating layer 1325 can be arranged at the first surface of the base element 1321 to cover each of the first signal line 1323a and the second signal line 1323b except for the end section (or one side) of the signal input element 1320.

[0503] An end section (or side) of the signal input element 1320, comprising an end section (or side) of the base element 1321 and an end section (or side) 1325a of the insulating layer 1325, can be inserted (or received) between the first cover element 1313 and the second cover element 1315 and can be fixed between the first cover element 1313 and the second cover element 1315 by a first adhesive layer 1317 and the second adhesive layer 1319. Similarly, the end section (or side) of the first signal line 1323a can be electrically connected to the first electrode part 1311b of the vibration generating part 1311, and the end section (or side) of the second signal line 1323b can be electrically connected to the second electrode part 1311c of the vibration generating part 1311.Additionally, the end section (or one side) of the signal supply element 1320 can be inserted (or received) and fixed between the vibration generating part 1311 and the first cover element 1313, thus preventing a contact fault between the vibration generator 1310 and the signal supply element 1320 caused by the movement of the signal supply element 1320.

[0504] In the signal input element 1320, one embodiment of the disclosure, each end section (or side) of the base element 1321 and the end section (or side) 1325a of the insulating layer 1325 can be removed. For example, each end section of the first signal line 1323a and the end section of the second signal line 1323b can be exposed on the outside without being supported or covered by each end section (or side) of the base element 1321 or the end section (or side) 1325a of the insulating layer 1325, respectively. For example, the end section (or side) of each of the first signal line 1323a and the second signal line 1323b can project (or extend) such that it has a certain length from an end 1321e of the base element 1321 or an end 1325e of the insulating layer 1325.Accordingly, each of the end section (or remote end section or one side) of each of the first signal line 1323a and the second signal line 1323b can be bent individually or independently.

[0505] The end section (or one side) of the first signal line 1323a, which is not supported by the end section (or one side) of the base element 1321 and the end section 1325a of the insulating layer 1325, may be directly connected to or in direct contact with the first electrode part 1311b of the vibration-generating part 1311. The end section (or one side) of the second signal line 1323b, which is not supported by the end section (or one side) of the base element 1321 and the end section 1325a of the insulating layer 1325, may be directly connected to or in direct contact with the second electrode part 1311c of the vibration-generating part 1311.

[0506] According to one embodiment of the disclosure, a section of the signal input element 1320 or a section of the base element 1321 can be arranged or inserted (or received) between the first cover element 1313 and the second cover element 1315, and thus the signal input element 1320 can be integrated (or configured) as a single body with the vibration-generating part 1311. Accordingly, the vibration-generating part 1311 and the signal input element 1320 can be configured as a single part (or component), thus achieving a unimaterialization effect.

[0507] According to one embodiment of the disclosure, the first signal line 1323a and the second signal line 1323b of the signal input element 1320 can be integrated (or configured) with the vibration generator 1310 as a single body, thus eliminating the need for a soldering process for an electrical connection between the vibration generator 1310 and the signal input element 1320. Accordingly, the manufacturing process and structure of the vibration device 333 and 335 can be simplified, and hazards associated with the soldering process can be reduced.

[0508] Fig. Figure 36 illustrates a vibration component, a further embodiment of the disclosure. Fig. Figure 36 illustrates a further embodiment of the vibration element, which was described above with reference to Fig. 33 to Fig. 35 is described.

[0509] With reference to Fig. 34 and Fig. 36. The vibration element 1311a can, in a further embodiment of the disclosure, comprise several first sections 1311a1 and several second sections 1311a2. For example, the several first sections 1311a1 and the several second sections 1311a2 can be arranged alternately and repeatedly in a second direction Y (or a first direction X).

[0510] Each of the several first sections 1311a1 may contain a section of inorganic material exhibiting a piezoelectric effect (or a piezoelectric property). For example, each of the several first sections 1311a1 may contain a piezoelectric inorganic material and / or a piezoelectric organic material. For example, each of the several first sections 1311al may be an inorganic section, a section of inorganic material, a piezoelectric section, a section of a piezoelectric material, or an electroactive section; however, embodiments of the disclosure are not limited thereto.

[0511] According to one embodiment of the disclosure, each of the multiple first sections 1311a1 can have a first width W1 parallel to the second direction Y (or the first direction X) and can be extended in the first direction X (or the second direction Y). Each of the multiple first sections 1311a1 can be substantially the same as a vibration part 1311a described above with reference to Fig. 33 to Fig. 35 is described, and therefore their repeated descriptions are omitted or briefly given below.

[0512] Each of the multiple second sections 1311a2 can be arranged between the multiple first sections 1311a1. For example, each of the multiple first sections 1311a1 can be arranged between two adjacent second sections 1311a2 of the multiple second sections 1311a2. Each of the multiple second sections 1311a2 can have a second width W2 parallel to the second direction Y (or the first direction X) and can be extended in the first direction X (or the second direction Y). The first width W1 can be the same as the second width W2 or different from it. For example, the first width W1 can be greater than the second width W2. For example, the first section 1311a1 and the second section 1311a2 can contain a line shape or a strip shape of the same size or different sizes.

[0513] Each of the multiple second sections 1311a2 can be configured to fill a gap between two adjacent first sections of the multiple first sections 1311a1. Each of the multiple second sections 1311a2 can be configured to fill a gap between two adjacent first sections of the multiple first sections 1311a1 and can thus be connected to or attached to the side surfaces of the adjacent first section 1311a1. According to one embodiment of the disclosure, each of the multiple first sections 1311a1 and the multiple second sections 1311a2 can be arranged (or laid out) parallel to each other in the same plane (or layer). Therefore, the vibration part 1311a can be extended to a desired size or length by lateral coupling (or connection) of the first sections 1311a1 and the second sections 1311a2.

[0514] According to one embodiment of the disclosure, each of the multiple second sections 1311a2 can absorb an impact exerted on the first sections 1311a1, thereby improving the overall durability of the first sections 1311a1 and imparting flexibility to the vibration-absorbing part 1311a. Each of the multiple second sections 1311a2 can contain an organic material exhibiting strain characteristics. For example, each of the multiple second sections 1311a2 can contain an epoxy-based polymer and / or an acrylic-based polymer and / or a silicone-based polymer, but embodiments of the disclosure are not limited thereto.For example, each of the several second sections 1311a2 can be an organic section, a section made of organic material, an adhesive section, a stretching section, a bending section, a damping section or a straining section, but embodiments of the disclosure are not limited thereto.

[0515] A first surface of each of the multiple first sections 1311a1 and of the multiple second sections 1311a2 can be common to the first electrode part 1311b. A second surface of each of the multiple first sections 1311a1 and of the multiple second sections 1311a2 can be common to the second electrode part 1311c. For example, the first electrode part 1311b and / or the second electrode part 1311c can be formed as pattern electrodes to correspond only to the multiple first sections 1311a1.

[0516] The multiple first sections 1311a1 and the multiple second sections 1311a2 can be arranged in (or connected to) the same plane, and thus the vibration element 1311a can, in a further embodiment of the disclosure, have a single thin-film type. Accordingly, the vibration generating element 1311 or the vibration generator 1310, which includes the vibration element 1311a, can be set into vibration by the first section 1311a1, which has a vibration characteristic, and can be bent into a curved shape by the second section 1311a2, which has flexibility.

[0517] Fig. Figure 37 illustrates a vibration component, a further embodiment of the disclosure. Fig. Figure 37 illustrates another embodiment of the vibration element, which was described above with reference to Fig. 33 to Fig. 35 is described.

[0518] With reference to Fig. 34 and Fig. 37 The vibration part 1311a can, in a further embodiment of the disclosure, include several first sections 1311a3 and a second section 1311a4, which is arranged between the several first sections 1311a3.

[0519] Each of the multiple first sections 1311a3 can be arranged such that they are spaced apart from each other along each of the first direction X and the second direction Y. For example, each of the multiple first sections 1311a3 can have a hexagonal shape of the same size and can be arranged in a grid shape, but embodiments of the disclosure are not limited thereto. For example, each of the multiple first sections 1311a3 can have a circular plate, an oval plate, or a polygonal plate of the same size, but embodiments of the disclosure are not limited thereto.

[0520] Each of the several first sections 1311a3 may be substantially the same as the first section 1311a1, which refers above to Fig. 36 is described, and therefore his repeated descriptions are omitted or briefly given below.

[0521] The second section 1311a4 can be arranged between the multiple first sections 1311a3 along either the first direction X and the second direction Y. The second section 1311a4 can be configured to fill a gap between two adjacent first sections 1311a3, or to be adjacent to or surrounding each of the multiple first sections 1311a3, and thus the second section 1311a4 can be connected to or attached to the first section 1311a3 to which it is adjacent. The second section 1311a4 can be substantially the same as the second section 1311a2 described above with reference to Fig. 36 is described, and therefore its repeated descriptions are omitted or briefly given below.

[0522] A first surface of each of the multiple first sections 1311a3 and of the second sections 1311a4 can be jointly connected to the first electrode part 1311b. A second surface of each of the multiple first sections 1311a3 and of the second sections 1311a4 can be jointly connected to the second electrode part 1311c. For example, the first electrode part 1311b and / or the second electrode part 1311c can be formed as pattern-shaped electrodes simply to correspond to the multiple first sections 1311a3.

[0523] The several first sections 1311a3 and the second section 1311a4 can be arranged on (or connected to) the same plane, and thus the vibration element 1311a can, according to a further embodiment of the disclosure, have a single thin-film type. Accordingly, the vibration generating element 1311 or the vibration generator 1310, which includes the vibration element 1311a, according to a further embodiment of the disclosure, can be set into vibration by the first section 1311a3, which has a vibration characteristic, and can be bent into a curved shape by the second section 1311a4, which has flexibility.

[0524] Fig. Figure 38 illustrates a vibration device as another embodiment of the disclosure. Fig. Figure 38 illustrates a vibration device containing one or more vibration generators, which are described above with reference to Fig. 7 are described.

[0525] With reference to Fig. 7 and Fig. 38. In a further embodiment of the disclosure, the vibration device 333 and 335 may include two or more vibration generators 333A, 333B, 335A and 335B. For example, the vibration device 333 and 335 may include a first vibration generator 333A and 335A and a second vibration generator 333B and 335B.

[0526] The first vibration generator 333A and 335A and the second vibration generator 333B and 335B can overlap or be stacked together to be displaced (or driven or set into vibration) in the same direction in order to maximize an amplitude displacement of the vibration device 333 and 335 or an amplitude displacement of a vibration element 331. For example, the first vibration generator 333A and 335A and the second vibration generator 333B and 335B can be substantially the same size, but embodiments of the disclosure are not limited to this. For example, the first vibration generator 333A and 335A and the second vibration generator 333B and 335B can be substantially the same size within a defect range of a manufacturing process, but embodiments of the disclosure are not limited to this.Therefore, the first vibration generator 333A and 335A and the second vibration generator 333B and 335B can maximize the amplitude shift of the vibration device 333 and 335 and / or the amplitude shift of the vibration element 331.

[0527] According to one embodiment of the disclosure, the first vibration generator 333A and 335A and / or the second vibration generator 333B and 335B can be connected to the vibration element 331 by an adhesive element 332 and 334, which is in Fig. 3 to Fig. Figure 32 illustrates how the vibration generators 333A and 335A can be connected or coupled to the vibration element 331 via the adhesive element 332 and 334.

[0528] Each of the first vibration generators 333A and 335A and of the second vibration generators 333B and 335B can be the same or substantially the same as the vibration generating part 1311 described above with reference to Fig. 33 to Fig. 37 is described, and thus a similar reference sign refers to a similar element, and their repeated descriptions are omitted or briefly given below.

[0529] The vibration device 333 and 335, a further embodiment of the disclosure, may also include an intermediate element 333M and 335M.

[0530] The intermediate element 333M and 335M can be arranged or connected between the first vibration generator 333A and 335A and the second vibration generator 333B and 335B. For example, the intermediate element 333M and 335M can be arranged or connected between the second cover element 1315 of the first vibration generator 333A and 335A and the first cover element 1313 of the second vibration generator 333B and 335B. For example, the intermediate element 333M and 335M can be an adhesive element or a connecting element; however, embodiments of the disclosure are not limited to these.

[0531] The intermediate element 333M and 335M, in one embodiment of the disclosure, can be configured in a material containing an adhesive layer that exhibits good adhesion or bonding strength with respect to each of the first vibration generator 333A and 335A and the second vibration generator 333B and 335B. For example, the intermediate element 333M and 335M can contain a foam pad, a double-sided adhesive tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, or an adhesive or the like; however, embodiments of the disclosure are not limited to these. For example, an adhesive layer of the intermediate element 333M and 335M can contain epoxy, acrylic, silicone, or urethane; however, embodiments of the disclosure are not limited to these.For example, the adhesive layer of the intermediate element 333M and 335M can contain a urethane-based material (or substance) that exhibits a relative strain characteristic. Accordingly, the vibration loss caused by displacement interference between the first vibration generator 333A and 335A and the second vibration generator 333B and 335B can be reduced or minimized, or each of the first vibration generator 333A and 335A and the second vibration generator 333B and 335B can be freely displaced (or set into vibration or driven).

[0532] The vibration device 333 and 335, in a further embodiment of the disclosure, can include the first vibration generator 333A and 335A and the second vibration generator 333B and 335B, which are stacked (or layered or overlapping) to be set into vibration (or displaced or driven) in the same direction, and thus the magnitude of a displacement or an amplitude displacement can be maximized or increased. Similarly, the magnitude of a displacement (or a bending force or a driving force) or an amplitude of a displacement of the vibration element 331 can be maximized or increased.
