[0116] FIG. 8 is a schematic diagram of the first embodiment of the present invention. active Vibration member and second active 4 is a diagram showing the vibration amplitude (or displacement amplitude) of a vibrating member and a passive vibrating member. FIG.

[0117] Referring to FIG. active The drive signal (or the first drive signal) applied to the first vibration element 311 of the vibration member 310 is a second active It can have the same phase as the drive signal (or the second drive signal) applied to each of the 2-1 vibration element 331 and the 2-2 vibration element 332 of the vibration member 330. As a result, the first vibration element 311 and the 2-1 vibration element 331 and the 2-2 vibration element 332 can be bent (or displaced) into the same shape as each other. As a result, the vibration width (or displacement width) at the second edge portion of the first vibration element 311 can be maximized by adding the vibration width (or displacement width) at the first edge portion of each of the 2-1 vibration element 331 and the 2-2 vibration element 332. For example, the vibration generated by the first vibration element 311 and the vibration generated by each of the 2-1 vibration element 331 and the 2-2 vibration element 332 are reinforced by each other, so that the vibration efficiency is improved and the vibration width (or displacement width) can be maximized.

[0119] Comparing the partial vibration width (or displacement width) of the passive vibration member 350 shown in FIG. 8 with the partial vibration width (or displacement width) of the passive vibration member 350 shown in FIG. 5, the passive vibration member 350 shown in FIG. 8 has a first vibration width (Wb1), a second vibration width (Wb2), and a third vibration width (Wb3) related to the straightness of the wind, the wind speed, and the wind volume. 3 Vibration width (Wb 3 ) can be increased, and the second 4 Vibration width (Wb 4 ) but It can be reduced.

[0120] Therefore, the passive vibration member 350 includes a hard region and a soft region by the first to third regions 351, 352, and 353 made of different materials, so that the vibration (or displacement width) of the first side 350a or the end adjacent to the air outlet of the housing can be increased, and thus it is possible to generate wind with enhanced linearity, increase the wind speed and volume, and concentrate the wind direction. Also, the passive vibration member 350 has a first side 350a or an end connected to the connecting member 360. By By being connected to the second active vibration member 330, the vibration (or displacement amplitude) of the first and second edge portions can be reduced, thereby preventing or minimizing the wave phenomenon and the resulting noise generation.

For example, the weight member 370 may be disposed at the intersection of the first active vibration member 310 and the second active vibration member 330. For example, the weight member 370 may be disposed between each of the second-first active vibration member 330-1 and the second-second active vibration member 330-2 and the first active vibration member 310. For example, the weight member 370 may be disposed between the first adhesive member 320 and the first active vibration member 310, or between the adhesive member 320 and the second active vibration member 330. For example, the weight member 370 may be disposed between each of the second-first active vibration member 330-1 and the second-second active vibration member 330-2 and the first adhesive member 320.

[0124] The weight member 370 may be disposed between each of the 2-1 vibration element 331 and the 2-2 vibration element 332 and the first vibration element 311. For example, the weight member 370 may be disposed between the first vibration element 311 and the first adhesive member 320. For example, the weight member 370 may be disposed between each of the 2-1 vibration element 331 and the 2-2 vibration element 332 and the first adhesive member 320. For example, the weight member 370 may be built into the first adhesive member 320. For example, the adhesive member 320 may be disposed so as to entirely surround the weight member 370.

[0125] The weight member 370 according to the embodiment of the present specification may include a first weight member 371 and a first weight member 372. For example, the weight member 370 may include a first weight portion, a weight member, a mass ( mass For example, the first-1 weight member 371 and the first-2 weight member 372 may be a pair of weight parts, a pair of weight members, a pair of masses ( mass In this specification, the No. 1-1 weight member 371 and the No. 1-2 weight member 372 may be the first weight member and the second weight member, and the No. 1-1 and No. 1-2 do not limit the contents of this specification.

[0126] According to embodiments of the present disclosure, each of the 1-1 weight member (or 1-1 weight portion) 371 and the 1-2 weight member (or 1-2 weight portion) 372 can include a first surface and a second surface.

[0127] A first surface of the 1-1 weight member 371 may be connected (or bonded) to the 1-1 adhesive member 371. A first surface of the 1-2 weight member 372 may be connected (or bonded) to the 1-2 adhesive member 372. A second surface of the 1-1 weight member 371 may be connected (or bonded) to a first edge portion of the vibration element 311 or the 2-1 vibration element 331. A second surface of the 1-2 weight member 372 may be connected (or bonded) to a first edge portion of the vibration element 311 or the 2-2 vibration element 332.

[0128] According to another embodiment of the present specification, the weight member 370 may be configured in one housing without being separated into the 1-1 weight member 371 and the 1-2 weight member 372. For example, the weight member 370 may have a polygonal prism shape or a cylindrical shape having a size equal to or smaller than the center of the first vibration element 311. For example, a first surface of the weight member 370 may be connected (or bonded) to the adhesive member 320.

For example, the weight member 370 or the 1-1st and 1-2nd weight members 371, 372 may be made of an elastic material having a strength less than the warping strength of the vibration elements 311, 331, 332. For example, the weight member 370 or the 1-1st and 1-2nd weight members 371, 372 may be made of the same elastic material as the coupling member 335 or the connecting member 360, but the embodiment of the present specification is not limited thereto. For example, the weight member 370 or the 1-1st and 1-2nd weight members 371, 372 may be made of an elastomer, but the embodiment of the present specification is not limited thereto.

[0130] According to another embodiment of the present disclosure, the weight member 370 or the first and second weight members 371, 372 may include an adhesive layer. But well or without an adhesive layer It is not necessary For example, when the weight member 370 or the first and second weight members 371, 372 do not include an adhesive layer, the vibration device 500 according to the present specification may further include an adhesive member attached to the first surface of the weight member 370.

[0131] The weight member 370 or the 1-1 and 1-2 weight members 371 and 372 are weight bodies (or mass bodies) that increase the weight (or mass) of the 1st vibration element 311 and the 2-1 and 2-2 vibration elements 331 and 332, respectively, thereby decreasing the lowest resonance frequency (or lowest natural frequency) of each of the vibration elements 311, 331, and 332. mass ) As a result, the first vibration element 311 and the 2-1 and 2-2 vibration elements 331 and 332 can vibrate at a relatively lower frequency by further reducing the lowest resonance frequency (or the lowest natural frequency).

[0132] Therefore, the passive vibration member 350 can have a larger vibration amplitude (or displacement amplitude) due to the composite vibration (or compound vibration) of the first active vibration member 310 and the second active vibration member 330. As a result, the passive vibration member 350 can vibrate with a larger displacement due to the larger displacement (or vibration) of the first active vibration member 310, and can blow stronger and more wind (or air) to the outside through the air outlet 101 of the housing 100. In addition, the passive vibration member 350 can blow (or exhaust) wind (or air) without noise due to vibration in the ultra-low frequency range. For example, the passive vibration member 350 can vibrate at a vibration frequency corresponding to the frequency of the ultra-low frequency range that the user cannot hear. For example, the passive vibration member 350 can vibrate at a vibration frequency corresponding to the frequency of the ultra-low frequency range that the user cannot hear. For example, the passive vibration member 350 can blow (or exhaust) wind (or air) to the outside through the air outlet 101 of the housing 100 without noise due to vibration in the ultra-low frequency range. Hz For example, the passive vibration member 350 can vibrate at a vibration frequency corresponding to the following ultra-low frequency band: Hz ~Dozens Hz By vibrating at the lowest vibration frequency (or lowest vibration frequency) of the device, it is possible to generate wind (or air) by vibrating at a noise that the user cannot hear.

[0134] The auxiliary weight member 375 may be connected to the second active vibration member 330, but the embodiment of the present specification is not limited thereto. For example, the auxiliary weight member 375 may be connected to the center of the rear surface of the first vibration element 311. The auxiliary weight member 375 may be made of the same elastic material as the weight member 370. The auxiliary weight member 375 may be modified to have a polygonal column shape or a cylindrical shape having a size equal to or smaller than the center of the first vibration element 311. As a result, the vibration device 300 according to another embodiment of the present specification may have a larger vibration width (or displacement width) due to the composite vibration (or composite vibration) of the first active vibration member 310 and the second active vibration member 330 by further including at least one of the weight member 370 and the auxiliary weight member 375. Therefore, the passive vibration member 350 may have a larger vibration width (or displacement width) due to the composite vibration (or composite vibration) of the first active vibration member 310 and the second active vibration member 330. As a result, the passive vibration member 350 vibrates with a larger displacement due to a larger displacement (or vibration) of the first active vibration member 310, and can blow stronger and more wind (or air) to the outside through the air outlet 101 of the housing 100.
