[0035] Reference will now be made in detail to embodiments of the present disclosure, examples of which may be illustrated in the accompanying drawings. In the following description, detailed descriptions of well-known functions or configurations may be omitted for the sake of brevity when it is determined that such descriptions may unnecessarily obscure aspects of the present disclosure. The described progression of processing steps and / or operations are examples; however, except for steps and / or operations that must occur in a specific order, the order of steps and / or operations is not limited to that set forth herein and may be varied.

[0036] Unless otherwise specified, the same reference numerals may denote the same elements throughout the text, even if they are shown in different figures. In one or more aspects, unless otherwise specified, the same elements (or elements with the same names) in different figures may have the same or substantially the same functions and characteristics. The names of the various elements used in the following description are selected for convenience only and may therefore differ from the names used in the actual product.

[0037] The advantages and features of the present disclosure and their implementation methods are illustrated by the embodiments described with reference to the accompanying drawings. However, the present disclosure may be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure is thorough and complete and fully conveys the scope of the present disclosure to those skilled in the art. Furthermore, the present disclosure is limited only by the claims and their equivalents.

[0038] The shapes, sizes, areas, ratios, angles, quantities and the like disclosed in the drawings for describing the embodiments of the present disclosure are merely examples, and therefore, the present disclosure is not limited to the details shown.

[0039] When the terms "comprising," "having," "including," "containing," "consisting of," "composed of," "formed of," etc. are used, one or more other elements may be added unless a term such as "only" is used. The terms used in this disclosure are only for describing specific embodiments and are not intended to limit the scope of the disclosure. The terms used herein are only for describing example embodiments and are not intended to limit the scope of the disclosure. Terms in the singular may include plural forms unless the context clearly indicates otherwise. The word "exemplary" is used to mean used as an example or illustration. An embodiment is an example embodiment. An aspect is an example aspect. Any implementation described herein as an "example" is not necessarily to be construed as better or superior to other implementations.

[0040] In one or more aspects, elements, features, or corresponding information (e.g., levels, ranges, dimensions, sizes, etc.) are interpreted as including errors or tolerances, even though no explicit description of such errors or tolerances is provided. Errors or tolerances may be caused by various factors (e.g., process factors, internal or external influences, noise, etc.). In addition, the term "may" includes all meanings of the term "can."

[0041] When describing a positional relationship, when using "up", "above", "down", "above", "below", "below", "near", "close to", or "adjacent", "next to", or the like to describe the positional relationship between two components, one or more other components may be disposed between the two components unless a more restrictive term such as "immediately", "directly", or "closely" is used. For example, when a structure is described as being "up", "above", "down", "above", "below", "below", "near", "close to", or "adjacent" another structure, "next to", or "next to" another structure, the description should be interpreted as including situations in which the structures are in contact with each other and situations in which one or more additional structures are disposed therebetween or interposed therebetween. In addition, the terms "front", "back", "left", "right", "top", "bottom", "downward", "upward", "upper", "lower", or the like refer to an arbitrary reference system.

[0042] When describing time relationships, when using "after", "subsequently", "next", "before", "previous", etc. to describe the time order, discontinuous or non-sequential situations can be included, unless more restrictive terms such as "just", "immediately" or "directly" are used.

[0043] It will be understood that although the terms "first", "second" etc. can be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this disclosure, the first element can be the second element, and similarly, the second element can be the first element. In addition, without departing from the scope of this disclosure, the first element, the second element, etc. can be arbitrarily named according to the convenience of those skilled in the art. The terms "first", "second" etc. can be used to distinguish components from each other, but the function or structure of the components is not limited by the serial number or component name in front of the components.

[0044] When describing elements of the present disclosure, terms such as "first," "second," "A," "B," "(a)," "(b)," etc. may be used. These terms are intended to distinguish corresponding elements from other elements, and are not used to limit the nature, basis, order, or number of the elements.

[0045] When an element or layer is “connected,” “coupled,” or “bonded” to another element or layer, unless otherwise specified, the element or layer may be not only directly connected, coupled, or bonded to the other element or layer, but also indirectly connected, coupled, or bonded to the other element or layer with one or more intermediate elements or layers disposed or interposed therebetween.

[0046] Regarding statements that an element or layer is “contacting,” “overlapping,” etc., with another element or layer, unless otherwise specified, the element or layer may not only be directly in contact with, overlap, etc., but also be indirectly in contact with, overlap, etc., with another element or layer with one or more intermediate elements or layers disposed or interposed between the elements or layers.

[0047] The term "at least one" should be understood to include any and all combinations of one or more associated listed items. For example, the meaning of "at least one of the first, second, and third items" refers to a combination of two or more proposed items from the first, second, and third items, as well as only one of the first, second, or third items. The expression "first element, second element, and / or" third element should be understood as one of the first, second, and third elements or as any or all combinations of the first, second, and third elements. By way of example, A, B, and / or C can refer to only A; only B; only C; any one or some combination of A, B, and C; or all of A, B, and C. In addition, the expression "element A / element B" can be understood as element A and / or element B.

[0048] In one or more aspects, unless otherwise specified, for convenience, the terms "between" and "among" may be used interchangeably. For example, the expression "between a plurality of elements" may be understood as "among a plurality of elements." In another example, the expression "among a plurality of elements" may be understood as "between a plurality of elements." In one or more examples, the number of elements may be two. In one or more examples, the number of elements may be more than two.

[0049] In one or more aspects, unless otherwise specified, for convenience, the phrases "mutually" and "each other" may be used interchangeably. For example, the expression "mutually different" may be understood as mutually different. In another example, the expression "mutually different" may be understood as mutually different. In one or more examples, the number of elements involved in the above statements may be two. In one or more examples, the number of elements involved in the above statements may be more than two.

[0050] In one or more aspects, unless otherwise specified, the phrases "one or more of" and "one or more of" may be used interchangeably for convenience. In one or more aspects, unless otherwise specified, the term "nth" or "n" may be used interchangeably for convenience. th " can refer to "nnd" or "n nd ” (For example, 2 nd , where n is 2), or "nrd" or "n rd ” (for example, 3rd, where n is 3), and n can be a natural number.

[0056] The housing 100 may be a main body, body, or housing of the device, but embodiments of the present disclosure are not limited thereto. For example, the housing 100 may be in a box shape including a receiving space AS, one or more blowing holes 101, and one or more suction portions (or air suction portions) 103. The housing 100 according to an embodiment of the present disclosure may include a first housing 110 and a second housing 130.

[0057] The first housing 110 may include a first case, a lower case, a lower frame, or a lower body, but the embodiments of the present disclosure are not limited thereto. The first housing 110 may include a bottom plate portion 111 and a sidewall portion 113 .

[0058] The bottom plate portion 111 may be a bottom plate frame or a lower cover having a certain size. The side wall portion 113 may be connected to the outer periphery of the bottom plate portion 111. For example, the side wall portion 113 may have a certain height and may be connected to be perpendicular to the outer periphery of the bottom plate portion 111. The side wall portion 113 may be implemented to have a certain height along the outer periphery of the bottom plate portion 111, and thus may provide an accommodation space AS above the bottom plate portion 111. Therefore, the first housing 110 may include a box shape having a front opening portion (or an upper opening portion).

[0059] The side wall portion 113 may include a plurality of side wall portions 113a, 113b, 113c, and 113d. The side wall portion 113 may include a first side wall portion 113a, a second side wall portion 113b, a third side wall portion 113c, and a fourth side wall portion 113d.

The fourth side wall portion 113d may realize the second long side (or second short side) of the housing 100 or the fourth side portion of the housing 100. For example, each of the first long side and the second long side of the shell 100 (or the first shell 110) can be parallel to the first direction X, and each of the first short side and the second short side of the shell 100 (or the first shell 110) can be parallel to the second direction Y intersecting with the first direction X, but the embodiments of the present disclosure are not limited thereto.

[0060] The second housing 130 may be provided on the first housing 110. The second housing 130 may be connected to the sidewall portion 113 of the first housing 110 to cover the accommodation space AS of the first housing 110. For example, the second housing 130 may be detachably connected to the first housing 110. For example, the second housing 130 may be a second housing, an upper housing, an upper frame, an upper body, an upper cover, a cover frame, or a cover plate, but embodiments of the present disclosure are not limited thereto.

[0061] The housing 100 according to an embodiment of the present disclosure may include one or more blowing holes 101 and one or more suction portions 103 .

[0062] One or more blowing holes 101 can be provided at one of the multiple side portions of the side surface of the housing 100. For example, one or more blowing holes 101 can be provided to pass through the first side portion (or first sidewall portion 113a) of the first to fourth side portions of the housing 100. For example, one or more blowing holes 101 can be provided to pass through the first side portion of the housing 100 along the first direction X and extend along the second direction Y. For example, one or more blowing holes 101 can include one or more slots or slits. Optionally, an air filter can be provided at one or more blowing holes 101.

[0063] One or more suction parts 103 can be arranged at one or more of the other side parts except one side part provided with the blowing hole 101 among the multiple side parts of the side surface of the housing 100. As an embodiment of the present disclosure, one or more suction parts 103 can be implemented to pass through one or more of the second to fourth side parts of the housing 100. For example, one or more suction parts 103 can be implemented to pass through each of the third and fourth side parts of the housing 100. As another embodiment of the present disclosure, one or more suction parts 103 can be implemented to pass through the second housing 130 of the housing 100 along the third direction Z. For example, the third direction Z can be parallel to the thickness (or height) direction of the housing 100. One or more suction parts 103 may include one or more slots or slits. Optionally, an air filter can be provided at one or more suction parts 103.

[0064] The vibration device 300 can be arranged in the accommodating space AS of the housing 100, and can be implemented to vibrate (or displace or drive) based on the driving signal input thereto to blow out (or discharge) wind (or air) through one or more blowing holes 101. The vibration device 300 can be implemented to have a vibration frequency corresponding to the frequency of a sub-bass sound band that the user cannot hear. For example, the vibration device 300 can be implemented to have a vibration frequency corresponding to the frequency of a sub-bass sound band of 100 Hz or less. For example, the vibration device 300 can be implemented to have a minimum vibration frequency (or minimum vibration frequency) of several Hz to tens of Hz, and therefore, can vibrate with a noise that the user cannot hear to generate wind (or air), and can blow out (or discharge) the wind (or air) to the outside through one or more blowing holes 101.

[0065] The vibration device 300 may be connected across the inner surface of the third side portion and the fourth side portion of the housing 100 to face the one or more blowing holes 101 of the housing 100. The vibration device 300 may be implemented in the accommodation space AS of the housing 100 to generate wind (or air) based on the vibration of the passive vibration member 350 based on the composite vibration (or displacement or drive) of the multiple active vibration members 310 and 330. For example, the multiple active vibration members 310 and 330 and the passive vibration member 350 may be implemented as a composite structure having a 2-degree-of-freedom vibration model.

[0066] Figure 3 It shows Figure 1 and Figure 2 1 is a perspective view of a vibration device 300 according to an embodiment of the present disclosure.

For example, the first active vibration member 310 may be disposed in the accommodation space AS of the housing 100 parallel to the first direction X. For example, in the accommodation space AS of the housing 100, the first active vibration member 310 may be disposed between the bottom plate portion 111 of the first housing 110 and the second housing 130. The first active vibration member 310 may be connected to the passive vibration member 350 in the accommodation space AS of the housing 100. The first active vibration member 310 may include a first vibration component 311. For example, the first vibration component 311 may be connected to the passive vibration member 350.

[0069] The second active vibration member 330 may be disposed to intersect with and be connected to the first active vibration member 310. The second active vibration member 330 may be disposed in the accommodation space AS of the housing 100 parallel to a second direction Y intersecting with the first active vibration member 310, and may be connected to the first active vibration member 310. The second active vibration member 330 may be connected to a central portion of the first active vibration member 310. A portion of the second active vibration member 330 may be connected to the first active vibration member 310.

[0070] The second active vibration member 330 may include a 2-1st active vibration member 330-1 and a 2-2nd active vibration member 330-2, each of which is connected to the first active vibration member 310 and is connected to the inner side surface of the housing 100. The 2-1st active vibration member 330-1 and the 2-2nd active vibration member 330-2 may be arranged along a direction intersecting with the first active vibration member 310 and may be spaced apart from each other above the first active vibration member 310. For example, the 2-1st active vibration member 330-1 and the 2-2nd active vibration member 330-2 may be a pair of second active vibration members. In the present disclosure, the 2-1st active vibration member 330-1 and the 2-2nd active vibration member 330-2 may be the second active vibration member and the third active vibration member, but embodiments of the present disclosure are not limited to the numbers "2-1st" and "2-2nd".

For example, the 2-1st vibration device 331 and the 2-2nd vibration device 332 may be a pair of second vibration devices. The 2-1st vibration device 331 and the 2-2nd vibration device 332 may be arranged parallel to each other along a direction intersecting with the first vibration device 311, and may be spaced apart from each other above the first vibration device 311. For example, the 2-1st vibration device 331 and the 2-2nd vibration device 332 may be spaced apart from each other above the center portion of the first vibration device 311. In the present disclosure, the 2-1st vibration device 331 and the 2-2nd vibration device 332 may be a second vibration device (or vibration device) and a third vibration device (or vibration device), but the embodiments of the present disclosure are not limited to the numbers "2-1st" and "2-2nd".

[0072] The first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 may each have a quadrilateral shape including a short side and a long side, and may have a rectangular shape, for example. Each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 may have the same length, but embodiments of the present disclosure are not limited thereto. For example, each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 may have the same length within the length that can be arranged in the gap space GS.

[0073] The first vibration device 311 may be disposed to intersect each of the 2-1st vibration device 331 and the 2-2nd vibration device 332. For example, the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 may be two-dimensionally arranged in a "+" shape, but embodiments of the present disclosure are not limited thereto.

[0074] Each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 may include a first peripheral portion and a second peripheral portion, the first peripheral portion and the second peripheral portion being parallel to each other, and a center portion (or intersection portion) being located between the first peripheral portion and the second peripheral portion. The center portion of the first vibration device 311 may overlap with the first peripheral portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332. Therefore, the center portion of the first vibration device 311 may not overlap with the center portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332, and may be disposed between the center portions of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332.

[0075] One of the first peripheral portion and the second peripheral portion of the first vibration device 311 may be connected to the passive vibration member 350.

For example, the first peripheral portion of the first vibration device 311 may be connected to the passive vibration member 350.

[0076] The first peripheral portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332 may be spaced apart from each other and may be respectively connected to the central portion of the first vibration device 311. The second peripheral portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332 may be spaced apart from each other and may be respectively connected to the inner side surface of the housing 100. For example, the second peripheral portion of the 2-1st vibration device 331 may be connected to the inner side surface of the third side portion of the housing 100, and the second peripheral portion of the 2-2nd vibration device 332 may be connected to the inner side surface of the fourth side portion of the housing 100. For example, the second peripheral portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332 may be connected to the inner side surface of the housing 100 to have a cantilever structure.

[0077] Each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 may be a bending displacement vibration device (or a piezoelectric vibration device). For example, each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 may be a single-layer vibration device (or a piezoelectric vibration device) or a stacked vibration device (or a piezoelectric vibration device), but the embodiments of the present disclosure are not limited thereto.

[0078] Each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 can vibrate (or displace or drive) based on a driving signal input thereto. When contraction and expansion are alternately repeated based on the piezoelectric effect (or piezoelectric characteristics) according to a driving signal applied from the outside, each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 can vibrate (or displace or drive). The driving signal can be an alternating current (AC) signal, such as a sound signal, a vibration driving signal, or a voice signal. The 2-1st vibration device 331 and the 2-2nd vibration device 332 can vibrate (or displace or drive) based on the same driving signal. The driving signal applied to the 2-1st vibration device 331 and the 2-2nd vibration device 332 can have the same phase (or in phase) as the driving signal applied to the first vibration device 311, or can have an opposite phase (or anti-phase) relative to the phase of the driving signal applied to the first vibration device 311.

[0079] Each of the first vibration device 311, the 2-1st vibration device 331 and the 2-2nd vibration device 332 may include one or more piezoelectric devices. The one or more piezoelectric devices may include a piezoelectric layer, one or more first electrodes arranged at a first surface of the piezoelectric layer, and one or more second electrodes arranged at a second surface of the piezoelectric layer that is different from the first surface. For example, the piezoelectric layer may include a front surface and a rear surface. For example, the first surface of the piezoelectric layer may be a first area of ​​the front surface (or rear surface) of the piezoelectric layer, and the second surface of the piezoelectric layer may be a second area spaced apart from the first area of ​​the front surface (or rear surface) of the piezoelectric layer. For example, the first surface of the piezoelectric layer may be the front surface of the piezoelectric layer, and the second surface of the piezoelectric layer may be the rear surface of the piezoelectric layer.

[0080] In each of the first vibration device 311, the 2-1st vibration device 331 and the 2-2nd vibration device 332, the piezoelectric device may include a piezoelectric layer. The material of the piezoelectric layer is not limited thereto, but may include a piezoelectric material of a ceramic-based material capable of achieving relatively high vibration, or may include a piezoelectric ceramic material having a perovskite-based crystal structure. For example, the piezoelectric layer may be constructed as a piezoelectric material including lead (Pb) or a piezoelectric material not including lead (Pb).

[0081] The vibration device 300 according to an embodiment of the present disclosure may further include a first adhesive member 320 and a coupling member 335 .

[0082] The first bonding member 320 may be disposed between the first active vibration member 310 and the second active vibration member 330. For example, the first bonding member 320 may be disposed between the first active vibration member 310 and each of the 2-1st active vibration member 330-1 and the 2-2nd active vibration member 330-2. For example, the first bonding member 320 may be disposed between a pair of second active vibration members 330-1 and 330-2 and the first active vibration member 310. Therefore, each of the 2-1st active vibration member 330-1 and the 2-2nd active vibration member 330-2 may be connected to the first active vibration member 310 through the first bonding member 320, and thus may receive the vibration (or displacement) of the first active vibration member 310 to vibrate (or displace or drive).

[0083] The first bonding member 320 may be provided between the first vibration device 311 of the first active vibration member 310 and each of the 2-1st vibration device 331 of the 2-1st active vibration member 330-1 and the 2-2nd vibration device 332 of the 2-2nd active vibration member 330-2. For example, the first bonding member 320 may be provided between the pair of second vibration devices 331 and 332 and the first vibration device 311. Therefore, each of the 2-1st vibration device 331 and the 2-2nd vibration device 332 may be connected to the first vibration device 311 through the first bonding member 320, and thus, may receive the vibration (or displacement) of the first vibration device 311 to vibrate (or displace or drive).

[0084] The first bonding member 320 according to an embodiment of the present disclosure may include a 1-1st bonding member 321 and a 1-2nd bonding member 322. For example, the 1-1st bonding member 321 and the 1-2nd bonding member 322 may be a pair of bonding members. In the present disclosure, the 1-1st bonding member 321 and the 1-2nd bonding member 322 may be the first bonding member and the second bonding member, but the embodiments of the present disclosure are not limited to the numbers "1-1st" and "1-2nd".

[0085] The 1-1st bonding member (or 1-1st bonding portion) 321 may be bonded between the first peripheral portion of the 2-1st vibration device 331 and the first vibration device 311. The 1-1st bonding member 321 may be bonded between the first peripheral portion of the 2-1st vibration device 331 and the first side (or first portion) of the central portion of the first vibration device 311. Therefore, the first peripheral portion of the 2-1st vibration device 331 may be connected to the central portion of the first vibration device 311 through the 1-1st bonding member 321, and thus, may receive the vibration (or displacement) of the first vibration device 311 to vibrate (or displace or drive).

[0086] The 1-2nd bonding member (or the 1-2nd bonding portion) 322 may be bonded between the first peripheral portion of the 2-2nd vibration device 332 and the first vibration device 311. The 1-2nd bonding member 322 may be bonded between the first peripheral portion of the 2-2nd vibration device 332 and the second side (or second portion) of the central portion of the first vibration device 311. Therefore, the first peripheral portion of the 2-2nd vibration device 332 may be connected to the central portion of the first vibration device 311 through the 1-2nd bonding member 322, and thus may receive the vibration (or displacement) of the first vibration device 311 to vibrate (or displace or drive). Therefore, the first peripheral portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332 may vibrate (or displace or drive) together based on the vibration (or displacement) of the first vibration device 311.

[0087] According to another embodiment of the present disclosure, the first adhesive member 320 may not be divided into the 1-1st adhesive member 321 and the 1-2nd adhesive member 322 and may be attached at the entire center portion of the first vibrating device 311. Therefore, the first peripheral portion of the 2-1st vibrating device 331 and the second peripheral portion of the 2-2nd vibrating device 332 may be commonly connected to one first adhesive member 320 provided at the entire center portion of the first vibrating device 311 and may be spaced apart from each other above the one first adhesive member 320.

[0088] The first adhesive members 320, 321 and 322 can be constructed as an adhesive material that can be compressed and decompressed. For example, the adhesive members 320, 321 and 322 can be constructed as an adhesive material with a low elastic modulus. The adhesive members 320, 321 and 322 can be constructed as an adhesive resin material, an adhesive or an adhesive tape, etc., but the embodiments of the present disclosure are not limited thereto. The adhesive resin material may include one of an epoxy resin material, an acrylic resin material, a silicone resin material or a polyurethane resin material, but the embodiments of the present disclosure are not limited thereto. For example, the adhesive members 320, 321 and 322 may include an acrylic adhesive material having relatively good adhesion to acrylic and polyurethane and high hardness, so that the vibration of the first vibration device 311 is well transmitted to the first peripheral portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332.

[0089] The coupling member 335 may be coupled to the inner side surface of the housing 100 and may be implemented to support the second active vibration member 330. The coupling member 335 may be coupled to the inner side surface of the housing 100 and may support the second outer peripheral portion of each of the 2-1st vibration device 331 and the 2-2nd vibration device 332.

[0090] The coupling member 335 according to an embodiment of the present disclosure may include a first coupling member 335a and a second coupling member 335b. For example, the coupling member 335 may be a connecting portion, a supporting portion, a supporting member, an elastic connecting portion, an elastic supporting portion, or an elastic member. For example, the first coupling member 335a and the second coupling member 335b may be a pair of coupling members. For example, the first coupling member 335a may be a first connecting portion, a first supporting portion, a first supporting member, a first elastic connecting portion, a first elastic supporting portion, or a first elastic member. For example, the second coupling member 335b may be a second connecting portion, a second supporting portion, a second supporting member, a second elastic connecting portion, a second elastic supporting portion, or a second elastic member.

[0091] The first coupling member 335a may be implemented to connect the second peripheral portion of the 2-1st vibration device 331 to the inner side surface of the housing 100. For example, the first coupling member 335a may be implemented to connect the second peripheral portion of the 2-1st vibration device 331 to the inner side surface of the third side portion of the housing 100. The first coupling member 335a may be connected (or attached) to the inner side surface of the third side portion of the housing 100 and may be connected to the second peripheral portion of the 2-1st vibration device 331. For example, the first coupling member 335a may movably (or vibratingly) support the second peripheral portion of the 2-1st vibration device 331. For example, the first coupling member 335a may elastically or flexibly support the second peripheral portion of the 2-1st vibration device 331.

[0092] The first coupling member 335a according to an embodiment of the present disclosure may be connected (or coupled) to at least a portion of the second peripheral portion of the 2-1st vibration device 331. For example, the first coupling member 335a may be connected (or coupled) to each of the front surface and the rear surface of the second peripheral portion of the 2-1st vibration device 331 that face or are opposite to each other. For example, the first coupling member 335a may be connected (or coupled) to surround the second peripheral portion of the 2-1st vibration device 331. For example, the second peripheral portion of the 2-1st vibration device 331 may be inserted into the first coupling member 335a. Therefore, the second peripheral portion of the 2-1st vibration device 331 may be vibrationally (or displaceably) connected to the inner side surface of the housing 100 by the first coupling member 335a to have a cantilever structure.

[0093] The second coupling member 335b may be implemented to connect the second peripheral portion of the 2-2nd vibration device 332 to the inner side surface of the housing 100. For example, the second coupling member 335b may be implemented to connect the second peripheral portion of the 2-2nd vibration device 332 to the inner side surface of the fourth side portion of the housing 100. The second coupling member 335b may be connected (or attached) to the inner side surface of the fourth side portion of the housing 100, and may be connected to the second peripheral portion of the 2-2nd vibration device 332. For example, the second coupling member 335b may movably (or vibratingly) support the second peripheral portion of the 2-2nd vibration device 332. For example, the second coupling member 335b may elastically or flexibly support the second peripheral portion of the 2-2nd vibration device 332.

[0094] The second coupling member 335b according to an embodiment of the present disclosure may be connected (or coupled) to at least a portion of the second peripheral portion of the 2-2nd vibration device 332. For example, the second coupling member 335b may be connected (or coupled) to each of the front surface and the rear surface of the second peripheral portion of the 2-2nd vibration device 332 that face or are opposite to each other. For example, the second coupling member 335b may be connected (or coupled) to surround the second peripheral portion of the 2-2nd vibration device 332. For example, the second peripheral portion of the 2-2nd vibration device 332 may be inserted into the second coupling member 335b. Therefore, the second peripheral portion of the 2-2nd vibration device 332 may be vibrationally (or displaceably) connected to the inner side surface of the housing 100 through the second coupling member 335b to have a cantilever structure.

[0095] The coupling members 335, 335a, and 335b according to an embodiment of the present disclosure may include an elastic material having elasticity or flexibility. The coupling members 335, 335a, and 335b may be constructed as an elastomer having a lower elastic modulus (or Young's modulus) than each of the vibration devices 311, 331, and 332. For example, the coupling members 335, 335a, and 335b may include double-sided tape, single-sided tape, double-sided foam tape, or double-sided adhesive foam pad, but the embodiments of the present disclosure are not limited thereto. For example, the coupling members 335, 335a, and 335b may include an elastic pad, such as a rubber pad or a silicone pad, which has adhesive properties and can be compressed and decompressed. For example, the adhesive layer of the coupling members 335, 335a, and 335b may include an acrylic adhesive material having relatively good adhesive force and high hardness.

[0096] The passive vibration member 350 may be connected to the first peripheral portion of the first active vibration member 310 and may be disposed between the blowing hole 101 of the housing 100 and the first active vibration member 310. The passive vibration member 350 may vibrate based on the displacement (or vibration or drive) of the first active vibration member 310 to generate wind. For example, the passive vibration member 350 may vibrate based on the displacement (or vibration or drive) of the first active vibration member 310 to blow wind (or air) out to the outside through the blowing hole 101 of the housing 100. For example, the passive vibration member 350 may be a wind generating member, a blowing member, a wing member, a blowing wing, a vibration plate, a wind generating plate, a blowing plate, or a fan, but embodiments of the present disclosure are not limited thereto.

[0097] The passive vibration member 350 can blow out (or discharge) wind (or air) silently based on the vibration of the super bass sound band. For example, the passive vibration member 350 can vibrate at a vibration frequency corresponding to the frequency of the super bass sound band that the user cannot hear. For example, the passive vibration member 350 can vibrate at a vibration frequency corresponding to the frequency of the super bass sound band of 100 Hz or less. For example, the passive vibration member 350 can vibrate at a minimum vibration frequency (or minimum vibration frequency) of several Hz to tens of Hz, and therefore, can vibrate to generate wind (or air) with noise that the user cannot hear.

[0098] The passive vibration member 350 according to an embodiment of the present disclosure may include a relatively lightweight and flexible material. For example, the passive vibration member 350 according to an embodiment of the present disclosure may include one or more materials selected from wood, rubber, plastic, fiber, cloth, paper, flexible metal, and leather, but the embodiments of the present disclosure are not limited thereto.

[0099] The passive vibration member 350 according to an embodiment of the present disclosure may have a square shape or a rectangular shape, but the embodiment of the present disclosure is not limited thereto and may have a polygonal shape, a non-polygonal shape, a semicircular shape, or a semi-elliptical shape. For example, the passive vibration member 350 may have a rectangular shape, wherein the first side (or first long side) 350a faces the blowing hole 101 of the housing 100, and each of the two corner portions 350c1 and 350c2 of the first side 350a is rounded in a curved shape.

[0100] The vibration device 300 according to an embodiment of the present disclosure may further include a second adhesive member 340 .

[0101] The second bonding member 340 may be disposed between the first active vibration member 310 and the passive vibration member 350. For example, the second bonding member 340 may be disposed between the first peripheral portion of the first active vibration member 310 and the passive vibration member 350. The second bonding member 340 may be disposed between the first vibration device 311 and the passive vibration member 350. For example, the second bonding member 340 may be disposed between the first peripheral portion of the first vibration device 311 and the passive vibration member 350.

[0102] The second adhesive member 340 according to an embodiment of the present disclosure can be configured as an adhesive material that can be compressed and decompressed. For example, the second adhesive member 340 can be configured as an adhesive material with a low elastic modulus. The second adhesive member 340 can be configured as an adhesive resin material, an adhesive, or an adhesive tape, etc., but the embodiments of the present disclosure are not limited thereto. For example, the second adhesive member 340 can be configured as an adhesive material substantially the same as the first adhesive member 320, but the embodiments of the present disclosure are not limited thereto.

[0103] The device or vibration device 300 according to an embodiment of the present disclosure may further include a balancing member 390 .

[0104] The balancing member 390 may be disposed at the first active vibration member 310 in parallel with the passive vibration member 350, with the second active vibration member 330 located between the balancing member 390 and the passive vibration member 350. For example, when the passive vibration member 350 is connected to a first peripheral portion of the first active vibration member 310, the balancing member 390 may be disposed at a second peripheral portion of the first active vibration member 310.

[0105] The balancing member 390 may be disposed at the first vibration device 311 in parallel with the passive vibration member 350, with the second active vibration member 330 located between the balancing member 390 and the passive vibration member 350. For example, when the passive vibration member 350 is connected to a first peripheral portion of the first vibration device 311, the balancing member 390 may be disposed at a second peripheral portion of the first vibration device 311.

[0106] The balancing member according to an embodiment of the present disclosure may have a weight (or mass) substantially the same as that of the passive vibration member 350. The balancing member 390 may be balanced so that the center of gravity of the first active vibration member 310 connected to the passive vibration member 350 is disposed at the center portion of the first active vibration member 310. For example, when the passive vibration member 350 vibrates, the balancing member 390 may balance the center of gravity of the first active vibration member 310 (or the first vibration device 311), thereby preventing or inhibiting horizontal vibration (or bias vibration) of the first active vibration member 310 (or the first vibration device 311). For example, the balancing member 390 may be referred to as a first mass portion, a first mass member, a first mass, or a first weight.

[0107] As described above, when the vibration device 300 according to an embodiment of the present disclosure is driven (or vibrated), the vibration device 300 may have a large vibration width (or displacement width) based on the composite vibration (or synthetic vibration) of the first active vibration member 310 and the second active vibration member 330, and therefore, the vibration width (or displacement width) of the passive vibration member 350 may increase, thereby increasing the intensity (or wind force) and speed (or wind velocity) of the wind generated based on the vibration of the passive vibration member 350.

[0108] According to an embodiment of the present disclosure, when the drive signals applied to the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332 respectively have the same phase, the total vibration width (or displacement width) of the vibration device 300 can be added to the vibration width (or displacement width) of the first vibration device 311 and the vibration width (or displacement width) of the 2-1st vibration device 331 (or the 2-2nd vibration device 332), and thus can be maximized. Therefore, the vibration device 300 according to an embodiment of the present disclosure can increase (or amplify) or maximize the vibration width (or displacement width) of the passive vibration member 350, and can vibrate the passive vibration member 350 at a minimum vibration frequency (or minimum vibration frequency) of several Hz to tens of Hz.

[0109] Therefore, the vibration device 300 according to an embodiment of the present disclosure can increase the intensity (or wind force) and speed (or wind velocity) of the wind generated based on the vibration of the passive vibration member 350, and can generate wind (or air) with noise that the user cannot hear, and can blow the wind (or air) out (or discharge) to the outside through one or more blowing holes 101.

[0110] Figure 4 A vibration model of a device according to an embodiment of the present disclosure is shown.

[0111] Reference Figures 2 to 4The device according to the embodiment of the present disclosure may have a composite structure of a 2-DOF vibration model. For example, the device according to the embodiment of the present disclosure may include a composite model of an undamped model and a damped model.

[0112] In the device according to an embodiment of the present disclosure, the second active vibration member 330 can be connected to the housing 100 via a coupling member 335, the first active vibration member 310 and the second active vibration member 330 can be connected to each other, and the first active vibration member 310 can be connected to the passive vibration member 350 via a second adhesive member 340. Therefore, the coupling member 335 can be modeled with a first spring constant k1, and the first and second active vibration members 310 and 330 can be modeled with a first mass m1. In addition, the passive vibration member 350 can have weight and elasticity, and therefore, can be modeled with a second spring constant k2, a damping coefficient c, and a second mass m2. Therefore, the first and second active vibration members 310 and 330 can be configured as undamped vibration models, and the passive vibration member 350 can be configured as a damped vibration model.

[0113] The force generated by the vibration of each of the first and second active vibration members 310 and 330 can cause the passive vibration member 350 to vibrate. The second mass m2 of the passive vibration member 350, which is affected by the force generated by the vibration of each of the first and second active vibration members 310 and 330, can be reduced due to the second spring constant k2 and the damping coefficient c. Therefore, the acceleration applied to each of the first, second, and passive vibration members 310, 330, and 350 can be increased based on the force generated by the vibration of each of the first and second active vibration members 310 and 330. Furthermore, the acceleration applied to each of the first and second active vibration members 310 and 330 can be further increased by the second spring constant k2 and the damping coefficient c. Therefore, the first and second active vibration members 310 and 330 can resonate with a large displacement. In addition, the displacement (or vibration or drive) of each of the first active vibration member 310 and the second active vibration member 330 may be gradually transmitted by the second spring constant k2 and the damping coefficient c, and therefore, the displacement (or vibration or drive) of each of the first active vibration member 310 and the second active vibration member 330 may not be blocked (or reduced) by the second mass m2 of the passive vibration member 350.

[0114] Therefore, the device according to the embodiment of the present disclosure can increase the displacement amount (or displacement width) of each of the first active vibration member 310, the second active vibration member 330 and the passive vibration member 350, thereby enhancing the intensity (or wind force) and speed (or wind speed) of the wind generated based on the vibration of the passive vibration member 350, and can generate wind (or air) with noise that the user cannot hear, and can blow the wind (or air) out (or discharge) to the outside through one or more blowing holes 101.

[0115] Figure 5 Shown Figure 2 and Figure 3 The vibration width (or displacement width) of each of the first active vibration member, the second active vibration member, and the passive vibration member shown in .

[0116] Reference Figure 5 , the drive signal (or first drive signal) applied to the first vibrator 311 of the first active vibration member 310 can have the same phase as the drive signal (or second drive signal) applied to each of the 2-1st vibrator 331 and the 2-2nd vibrator 332 of the second active vibration member 330. Therefore, each of the first vibrator 311, the 2-1st vibrator 331, and the 2-2nd vibrator 332 can bend (or displace or vibrate) in the same shape. Therefore, by adding the vibration width (or displacement width) of the first peripheral portion of each of the 2-1st vibrator 331 and the 2-2nd vibrator 332, the vibration width (or displacement width) of the second peripheral portion of the first vibrator 311 can be maximized. For example, the vibration generated by the first vibrator 311 and the vibration generated by each of the 2-1st vibrator 331 and the 2-2nd vibrator 332 can be enhanced, and thus, the vibration efficiency can be improved, and the vibration width (or displacement width) can be maximized.

[0117] The passive vibration member 350 may vibrate based on the vibration of the second peripheral portion of the first vibration device 311 to generate wind.

[0118] like Figure 5As shown by line AA' shown in FIG, the first vibration (or central vibration in the first direction) of the central portion of the passive vibration member 350 parallel to the first direction X with respect to the length direction of the first vibration device 311 may have a first vibration width (or displacement width) Wb1 that is greater than the first device vibration width (or displacement width) Wa1 of each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332. For example, the first vibration width (or displacement width) Wb1 may correspond to the maximum vibration width (or displacement width) of the passive vibration member 350 based on the composite vibration of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332.

[0119] like Figure 5 As shown by line BB' shown in, relative to the first direction X, the second vibration of the first peripheral portion of the passive vibration member 350 (or the peripheral vibration in the first direction) parallel to the central portion of the passive vibration member 350 can have a second vibration width (or displacement width) Wb2 that is smaller than the first vibration of the passive vibration member 350.

[0120] like Figure 5 As shown by line C-C' shown in, the third vibration (or outer vibration or end vibration) of the first end portion (or first side or first peripheral portion) of the passive vibration member 350 adjacent to the blowing hole of the shell can have a third vibration width (or displacement width) Wb3, which is smaller than the first vibration of the passive vibration member 350 and greater than the second vibration of the passive vibration member 350.

[0121] like Figure 5 As shown by line D-D' shown in FIG, the fourth vibration (or inner vibration) of the second end portion (or second side or second peripheral portion) of the passive vibration member 350, including the connection portion with the first vibration device 311, which is parallel to the first end portion of the passive vibration member 350, may have a fourth vibration width (or displacement width) Wb4 that is smaller than the second device vibration width (or displacement width) Wa2 of each of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332. For example, the fourth vibration width (or displacement width) Wb4 may correspond to the minimum vibration width (or displacement width) of the passive vibration member 350 based on the composite vibration of the first vibration device 311, the 2-1st vibration device 331, and the 2-2nd vibration device 332.

[0122] As described above, the passive vibration member 350 can generate wind according to the vibration widths (or displacement widths) Wb1 to Wb4 based on the section, and blow (or discharge) the wind to the outside through the blowing hole 101 of the housing. Figure 5As shown by the line AA' shown in FIG, the passive vibration member 350 can generate a relatively strong wind in the central portion of the passive vibration member 350 parallel to the first direction X, and can generate a relatively weak wind in the direction from the central portion of the passive vibration member 350 to the peripheral portion thereof. Therefore, based on the vibration of the central portion and the peripheral portion parallel to the first direction X, the passive vibration member 350 can blow (or discharge) relatively more wind to the outside through the blowing hole 101 of the housing. For example, the passive vibration member 350 can generate scattered wind or fresh wind, and can blow (or discharge) the wind to the outside through one or more blowing holes 101.

[0123] Figure 6 is a perspective view illustrating a vibration device according to another embodiment of the present disclosure. Figure 6 Shown by modifying Figures 1 to 3 The embodiment is realized by the passive vibration component in the vibration device shown in FIG. Figure 6 In the description of the present invention, elements other than the passive vibration member and related elements are denoted by the same reference numerals, and repeated description thereof may be omitted.

[0124] Reference Figure 6 In the vibration device 300 according to the embodiment of the present disclosure, the passive vibration member 350 may include a plurality of regions (or vibration regions) 351, 352, and 353 having different hardnesses from each other. For example, the passive vibration member 350 may include a first region (or vibration region) 351, a second region (or vibration region) 352, and a third region (or vibration region) 353 having different hardnesses from each other.

[0125] The first region (or vibration region) 351, the second region (or vibration region) 352, and the third region (or vibration region) 353 may be implemented in a radial shape (or fan shape) with respect to a center point CP, which is a connection portion connected to the first active vibration member 310. For example, the first region (or vibration region) 351, the second region (or vibration region) 352, and the third region (or vibration region) 353 may have different sizes from each other.

[0126] The first region 351 may have a first hardness (or a first stiffness). The first region 351 may have half or less of the total area (or size) of the passive vibration member 350. For example, the first region 351 may be implemented in a triangular shape starting from the connection portion connected to the first active vibration member 310. For example, the first region 351 may include the second side (or second long side or second end) 350b of the passive vibration member 350 and two corner portions of the second side 350b.

[0127] The first region 351 may include a 1-1 region 351a and a 1-2 region 351b. For example, the 1-1 region 351a and the 1-2 region 351b may be a pair of first regions 351. Each of the 1-1 region 351a and the 1-2 region 351b may have a triangular shape or a rectangular shape. The 1-1 region 351a and the 1-2 region 351b may be arranged adjacent to or parallel to the second active vibration member 330. For example, the 1-1 region 351a may be arranged adjacent to the 2-1 vibration device 331. For example, the 1-1 region 351a may be arranged adjacent to the 2-2 vibration device 332. In the present disclosure, the 1-1 region 351a and the 1-2 region 351b may be the first region and the second region, but the embodiments of the present disclosure are not limited to the numbers "1-1" and "1-2".

[0128] The second region 352 may have a second hardness (or second stiffness) that is the same as or different from the first hardness of the first region 351. For example, the second region 352 may have a second hardness that is less than the first hardness of the first region 351. The second region 352 may have half or less of the total area (or size) of the passive vibration member 350. For example, the area (or size) occupied by the first region 351 and the second region 352 may be half or less of the total area (or size) of the passive vibration member 350. For example, the area (or size) of the second region 352 may be equal to or less than the area (or size) of the first region 351.

[0129] The second area 352 can be implemented in a triangular shape starting from the connection portion connected to the first active vibration member 310. For example, the second area 352 may include the central portion and the first side (or first long side or first end) 350a of the passive vibration member 350. For example, the second area 352 may have a triangular shape or a regular triangle shape. For example, the vertex of the second area 352 having a triangular shape may be set at the connection portion connected to the first active vibration member 310. The second area 352 may be set between the 1-1 area 351a and the 1-2 area 351b of the first area 351, and may be set at the central portion of the passive vibration member 350.

[0130] The third region 353 may have a third hardness that is different from each of the first hardness of the first region 351 and the second hardness of the second region 352. The third hardness of the third region 353 may be less than each of the first hardness of the first region 351 and the second hardness of the second region 352. The third region 353 may include a material that is softer than each of the first region 351 and the second region 352. The third region 353 may have an area (or size) other than the total area (or size) of the passive vibration member 350, excluding the total area (or size) of the first region 351 and the second region 352. For example, the third region 353 may be formed in a triangular or fan-shaped shape starting from the connection portion connected to the first active vibration member 310. For example, the third region 353 may include two corner portions 350c1 and 350c2 of the first side (or first long side) 350a of the passive vibration member 350, or a curved portion of each of the two corner portions 350c1 and 350c2. For example, the third region 353 may be located between the first region 351 and the second region 352.

[0131] The third area 353 may include a 3-1 area 353a and a 3-2 area 353b. For example, the 3-1 area 353a and the 3-2 area 353b may be a pair of third areas 353. Each of the 3-1 area 353a and the 3-2 area 353b may have a triangular shape or a fan shape. For example, the 3-1 area 353a may be arranged between the 1-1 area 351a of the first area 351 and the second area 352. For example, the 3-2 area 353b may be arranged between the 1-2 area 351b of the first area 351 and the second area 352. In the present disclosure, the 3-1 area 353a and the 3-2 area 353b may be the fourth area and the fifth area, but the embodiments of the present disclosure are not limited to the numbers "3-1" and "3-2".

[0132] The first region 351, the second region 352, and the third region 353 may be implemented using different materials. For example, the first region 351, the second region 352, and the third region 353 may be implemented using different materials and / or different hardnesses. The first region 351, the second region 352, and the third region 353 may be connected to each other using a bonding structure of different materials or a connection structure of different materials.

[0133] As described above, according to another embodiment of the present disclosure, the passive vibration member 350 may include a hard region and a soft region based on the first region 351, the second region 352, and the third region 353. Therefore, the passive vibration member 350 may increase the vibration (or displacement width) of the first side 350a or the end portion of the blowing hole adjacent to the housing, and thus, with reference to the above Figure 5 The passive vibration member 350 described above can generate wind with stronger linearity than that of the passive vibration member 350 and can realize wind direction at a position separated from the passive vibration member 350 by a certain distance (for example, 5 cm or more).

[0134] Therefore, a device or vibration device 300 including a passive vibration member 350 according to another embodiment of the present disclosure can enhance the linearity of the wind generated based on the vibration of the passive vibration member 350, and thus, can achieve a wind direction at a position separated from it by a certain distance (for example, 5 cm or more), thereby enhancing wind force and wind speed.

[0135] Figure 7 is a perspective view illustrating a vibration device according to another embodiment of the present disclosure. Figure 7 Shown in Figure 6 In the vibration device shown, an embodiment of the connecting member is additionally configured. Figure 7 The connecting members shown can also be used for Figure 3 The vibration device shown. Therefore, Figure 7 In the description of the present invention, elements other than the connecting members and related elements are denoted by the same reference numerals, and repeated description thereof may be omitted.

[0136] Reference Figure 7 , the vibration device 300 according to another embodiment of the present disclosure may further include a connecting member 360 .

[0137] The connecting member 360 may be configured to be connected to the second active vibration member 330 and the passive vibration member 350. The connecting member 360 may be connected between the second side 350b of the passive vibration member 350 and the second active vibration member 330. For example, the connecting member 360 may be connected between two corner portions of the second side 350b of the passive vibration member 350 and the second active vibration member 330.

[0138] The connection member 360 according to an embodiment of the present disclosure may include a first connection member 361 and a second connection member 362 .

[0139] The first connecting member 361 according to an embodiment of the present disclosure may be connected between the first side (or first portion) of the second side 350b of the passive vibration member 350 and the 2-1st active vibration member 330-1 of the second active vibration member 330. For example, the first connecting member 361 may be connected between the first side of the second side 350b of the passive vibration member 350 and the 2-1st vibration device 331 of the second active vibration member 330. For example, the first connecting member 361 may be connected between the first side corner portion of the second side 350b of the passive vibration member 350 and the 2-1st vibration device 331 of the second active vibration member 330. As an embodiment of the present disclosure, when the connecting member 360 is applied to Figure 3 In the vibration device 300 shown in FIG. 1 , the first peripheral portion of the first connecting member 361 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the 2-1 vibration device 331, and the second peripheral portion of the first connecting member 361 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the passive vibration member 350. As another embodiment of the present disclosure, when the connecting member 360 is applied to Figure 7 In the vibration device 300 shown, the first peripheral portion of the first connecting member 361 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the 2-1 vibration device 331, and the second peripheral portion of the first connecting member 361 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the 1-1 region 351a of the passive vibration member 350.

[0140] The second connecting member 362 according to an embodiment of the present disclosure may be connected between the second side (or second portion) of the second edge 350b of the passive vibration member 350 and the 2-2 active vibration member 330-2 of the second active vibration member 330. For example, the second connecting member 362 may be connected between the second side of the second edge 350b of the passive vibration member 350 and the 2-2 vibration device 332 of the second active vibration member 330. For example, the second connecting member 362 may be connected between the second side corner portion of the second edge 350b of the passive vibration member 350 and the 2-2 vibration device 332 of the second active vibration member 330. As an embodiment of the present disclosure, when the connecting member 360 is applied to Figure 3In the vibration device 300 shown in FIG. 1 , the first peripheral portion of the second connecting member 362 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the 2-2 vibration device 332, and the second peripheral portion of the second connecting member 362 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the passive vibration member 350. As another embodiment of the present disclosure, when the connecting member 360 is applied to Figure 7 In the vibration device 300 shown, the first peripheral portion of the second connecting member 362 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the 2-2 vibration device 332, and the second peripheral portion of the second connecting member 362 can be connected to or attached to the first surface (or front surface) or the second surface (or rear surface) of the 1-2 region 351b of the passive vibration member 350.

[0141] The connecting members 360, 361 and 362 may be constructed as an adhesive material capable of compression and decompression. For example, the connecting members 360, 361 and 362 may be constructed as an elastomer having a lower elastic modulus (or Young's modulus) than each of the 2-1st vibration device 331 and the 2-2nd vibration device 332. The connecting members 360, 361 and 362 may include an elastic pad such as a rubber pad or a silicone pad, which has adhesive properties and can be compressed and decompressed. For example, the connecting members 360, 361 and 362 may include an acrylic-based adhesive material having relatively good adhesive force and high hardness, but the embodiments of the present disclosure are not limited thereto.

[0142] As described above, the connecting members 360, 361, and 362 can prevent or minimize the vibration of the second side 350b of the passive vibration member 350, and thus can prevent or minimize the fluctuation phenomenon in the second side 350b of the passive vibration member 350 and the occurrence of noise caused thereby. Therefore, the device or vibration device 300 including the connecting member 360 according to an embodiment of the present disclosure can prevent or minimize the fluctuation phenomenon in the second side 350b of the passive vibration member 350 and the occurrence of noise caused thereby.

[0143] Figure 8 Shown Figure 7 The vibration width (or displacement width) of each of the first active vibration member, the second active vibration member, and the passive vibration member is shown.

[0144] Reference Figure 8, the drive signal (or first drive signal) applied to the first vibrator 311 of the first active vibration member 310 can have the same phase as the drive signal (or second drive signal) applied to each of the 2-1st vibrator 331 and the 2-2nd vibrator 332 of the second active vibration member 330. Therefore, each of the first vibrator 311, the 2-1st vibrator 331, and the 2-2nd vibrator 332 can bend (or displace or vibrate) in the same shape. Therefore, by adding the vibration width (or displacement width) of the first peripheral portion of each of the 2-1st vibrator 331 and the 2-2nd vibrator 332, the vibration width (or displacement width) of the second peripheral portion of the first vibrator 311 can be maximized. For example, the vibration generated by the first vibrator 311 and the vibration generated by each of the 2-1st vibrator 331 and the 2-2nd vibrator 332 can be enhanced, and thus, the vibration efficiency can be improved, and the vibration width (or displacement width) can be maximized.

[0145] The passive vibration member 350 may vibrate based on the vibration of the second peripheral portion of the first vibration device 311 to generate wind.

[0146] and Figure 5 The passive vibration member 350 shown in FIG. 3 is a portion of the vibration width (or displacement width) compared to the Figure 8 In the partial vibration width (or displacement width) of the passive vibration member 350 shown, Figure 8 The passive vibration member 350 may increase each of the first vibration width Wb1, the second vibration width Wb2, and the third vibration width Wb3 associated with wind linearity, wind speed, and wind volume, and may reduce the fourth vibration width Wb4 associated with the wave phenomenon.

[0147] Therefore, because the passive vibration member 350 includes a hard area and a soft area, the vibration (or displacement width) of the first side 350a or the end portion adjacent to the blowing hole of the shell can be increased based on the first area 351, the second area 352, and the third area 353, and thus, wind with enhanced linearity can be generated, the wind speed and wind volume can be increased, and the wind direction can be concentrated. In addition, in the passive vibration member 350, the second side 350b or the end portion can be connected to the second active vibration member 330 by the connecting member 360, and thus, the vibration (or displacement width) of each of the first peripheral portion and the second peripheral portion can be reduced, thereby preventing or minimizing the occurrence of the fluctuation phenomenon and the noise caused thereby.

[0148] Figure 9 is a perspective view illustrating a vibration device according to another embodiment of the present disclosure. Figure 9 Shown in Figure 7The vibration device shown in FIG. 1 is implemented by additionally constructing a mass member. Figure 9 In the description of FIG. 1 , elements other than the mass member and related elements are denoted by the same reference numerals, and their repeated description may be omitted.

[0149] Reference Figure 9 , the device or vibration device 300 according to an embodiment of the present disclosure may further include a mass member 370 .

[0150] The mass member 370 may be disposed between the plurality of active vibration members 310 and 330. For example, the mass member 370 may be disposed at the intersection between the plurality of active vibration members 310 and 330. For example, the mass member 370 may be disposed between the first active vibration member 310 and the second active vibration member 330. For example, the mass member 370 may be disposed at the intersection between the first active vibration member 310 and the second active vibration member 330. For example, the mass member 370 may be disposed between each of the 2-1st active vibration member 330-1 and the 2-2nd active vibration member 330-2 and the first active vibration member 310. For example, the mass member 370 may be disposed between the first bonding member 320 and the first active vibration member 310 or between the first bonding member 320 and the second active vibration member 330. For example, the mass member 370 may be disposed between each of the 2-1st active vibration member 330-1 and the 2-2nd active vibration member 330-2 and the first bonding member 320.

[0151] The mass member 370 may be provided between the first vibration device 311 and each of the 2-1st vibration device 331 and the 2-2nd vibration device 332. For example, the mass member 370 may be provided between the first vibration device 311 and the first adhesive member 320. For example, the mass member 370 may be provided between each of the 2-1st vibration device 331 and the 2-2nd vibration device 332 and the first adhesive member 320. The mass member 370 may be embedded in the first adhesive member 320. The first adhesive member 320 may be provided to completely surround the mass member 370.

[0152] The mass member 370 may include a 1-th mass member 371 and a 1-2th mass member 372. For example, the mass member 370 may be a mass portion, a mass, or a weight. For example, the 1-th mass member 371 and the 1-2th mass member 372 may be a pair of first mass portions, a pair of mass members, a pair of masses, or a pair of weights. In the present disclosure, the 1-th mass member 371 and the 1-2th mass member 372 may be the first mass member and the second mass member, but embodiments of the present disclosure are not limited to the numbers "1-1" and "1-2."

[0153] According to an embodiment of the present disclosure, each of the 1-1th mass member (or 1-1th mass portion) 371 and the 1-2th mass member (or 1-2th mass portion) 372 may include a first surface and a second surface.

[0154] The first surface of the 1-1st mass member 371 may be connected (or bonded) to the 1-1st bonding member 321. The first surface of the 1-2nd mass member 372 may be connected (or bonded) to the 1-2nd bonding member 322. The second surface of the 1-1st mass member 371 may be connected (or bonded) to the first peripheral portion of the first vibrating device 311 or the 2-1st vibrating device 331. The second surface of the 1-2nd mass member 372 may be connected (or bonded) to the first peripheral portion of the first vibrating device 311 or the 2-2nd vibrating device 332.

[0155] According to another embodiment of the present disclosure, the mass member 370 may not be divided into the 1-1 mass member 371 and the 1-2 mass member 372, and may be constructed as a single body. For example, the mass member 370 may have a polygonal column shape or a circular column shape, the size of which is smaller than or equal to the center portion of the first vibration device 311. For example, the first surface of the mass member 370 may be connected (or bonded) to the first bonding member 320. The second surface of the mass member 370 may be connected (or bonded) to the center portion of the first vibration device 311, or may be connected (or bonded) to the first peripheral portion of each of the 2-1 vibration device 331 and the 2-2 vibration device 332.

[0156] The mass member 370 or the 1-1st mass member 371 and the 1-2nd mass member 372 may include an elastic material that can be used as a mass (or mass body) on the vibration devices 311, 331, and 332. For example, the mass member 370 or the 1-1st mass member 371 and the 1-2nd mass member 372 may include an elastic material having a strength less than the bending strength of each of the vibration devices 311, 331, and 332. For example, the mass member 370 or the 1-1st mass member 371 and the 1-2nd mass member 372 may include the same elastic material as the coupling member 335 or the connecting member 360, but embodiments of the present disclosure are not limited thereto. For example, the mass member 370 or the 1-1st mass member 371 and the 1-2nd mass member 372 may be formed of an elastomer, but embodiments of the present disclosure are not limited thereto.

[0157] According to another embodiment of the present disclosure, the mass member 370 or the 1-1st mass member 371 and the 1-2nd mass member 372 may include or may not include an adhesive layer. For example, when the mass member 370 or the 1-1st mass member 371 and the 1-2nd mass member 372 do not include an adhesive layer, the vibration device 300 according to another embodiment of the present disclosure may further include an adhesive member attached to the first surface of the mass member 370.

[0158] The mass member 370 or the 1-1st mass member 371 and the 1-2nd mass member 372 can serve as a mass (or mass body) that increases the mass (or weight) of each of the first vibration device 311 and the 2-1st vibration device 331 and the 2-2nd vibration device 332 to lower the lowest resonance frequency (or lowest natural frequency) of each of the vibration devices 311, 331, and 332. Therefore, the first vibration device 311 and each of the 2-1st vibration device 331 and the 2-2nd vibration device 332 can further lower the lowest resonance frequency (or lowest natural frequency) and, therefore, can vibrate at a relatively low frequency.

[0159] Therefore, based on the composite vibration (or synthetic vibration) of the first active vibration member 310 and the second active vibration member 330, the passive vibration member 350 can have a large vibration width (or displacement width). Therefore, the passive vibration member 350 can vibrate with a larger displacement based on the larger displacement (or vibration) of the first active vibration member 310, and thus, stronger and more wind (or air) can be blown out to the outside through the blowing hole 101 of the housing 100. In addition, the passive vibration member 350 can blow out (or discharge) wind (or air) silently based on the vibration of the sub-bass sound band. For example, the passive vibration member 350 can vibrate at a vibration frequency corresponding to the frequency of the sub-bass sound band that the user cannot hear. For example, the passive vibration member 350 can vibrate at a vibration frequency corresponding to the frequency of the sub-bass sound band of 100 Hz or less. For example, the passive vibration member 350 can vibrate with a minimum vibration frequency (or minimum vibration frequency) of several Hz to tens of Hz, and therefore, can vibrate to generate wind (or air) with noise that the user cannot hear.

[0160] like Figure 9 As shown, the vibration device 300 according to another embodiment of the present disclosure may further include an auxiliary mass member 375 for increasing the mass (or weight) of each of the first vibration device 311 and the 2-1st and 2-2nd vibration devices 331 and 332 .

[0161] The auxiliary mass member 375 can be connected to the first active vibration member 310 and the second active vibration member 330, but embodiments of the present disclosure are not limited thereto. For example, the auxiliary mass member 375 can be connected to the rear center portion of the first vibration device 311. The auxiliary mass member 375 can include the same elastic material as the mass member 370. For example, the auxiliary mass member 375 can be configured to have a polygonal column shape or a circular column shape, having a size smaller than or equal to the center portion of the first vibration device 311. Therefore, a device or vibration device 300 according to another embodiment of the present disclosure can also include at least one of the mass member 370 and the auxiliary mass member 375, and thus can have a larger vibration width (or displacement width) based on the composite vibration (or combined vibration) of the first active vibration member 310 and the second active vibration member 330. Therefore, based on the composite vibration (or combined vibration) of the first active vibration member 310 and the second active vibration member 330, the passive vibration member 350 can have a large vibration width (or displacement width). Therefore, the passive vibration member 350 can vibrate with a larger displacement based on the larger displacement (or vibration or drive) of the first active vibration member 310, and thus, stronger and more wind (or air) can be blown out to the outside through the blowing hole 101 of the housing 100.

[0162] Figure 9 At least one of the mass member 370 and the auxiliary mass member 375 shown may also be applied to Figure 3 and Figure 6 The vibration devices shown in the drawings are not described herein, and therefore, repeated description thereof may be omitted.
