  • a buffer member 103 may be provided between the top plate 211 and the support member 105, or between the support member 105 and the bottom plate 212.
  • the positioning portion 218 does not need to extend to about half the height of the outer walls 213, 214 as long as it can indicate the position where the vibrating body 102 is to be placed. For example, as shown in FIG. 14, it may only need to protrude slightly from the bottom plate 212 of the container 101 so that the position of the positioning portion 218 can be indicated. This allows the container 101 to be made lighter and vibration efficiency to be improved.
  • the upper container 101A and the lower container 101B do not need to be provided with the positioning portion 218.
  • the vibrating body 102 can be placed at a position desired by the user, and the degree of freedom in the placement pattern of the vibrating body 102 is increased.
  • the outer walls 213 and 214 may be provided with one or more holes for heat dissipation.
  • the holes connect the space inside the container 101 to the outside.
  • the vibrating body 102 generates heat, and the heat is trapped in the space inside the container 101. Therefore, by providing holes in the outer walls 213 and 214 that connect to the outside, heat can be released from the holes, improving the heat dissipation properties of the vibration unit 210.
  • the fixing parts 2151 and 2152 are provided in the space of the container 101, but they may be provided on the outer walls 213 and 214.
  • the method of fixing the upper container 101A and the lower container 101B is not limited to a method using fasteners such as bolts.
  • the outer wall 213 of the upper container 101A and the outer wall 214 of the lower container 101B may be joined and fixed by adhesive, ultrasonic welding, or the like.
  • the fixing parts 2151 and 2152 do not necessarily have to be provided.
  • Ribs may be provided on the outer walls 213, 214.
  • the ribs extend from the outer walls 213, 214 outward, i.e., toward the opposite side to the space inside the container 101. This increases the surface area of the container 101. This improves the heat dissipation of the vibration unit 210.
  • the load strength of the outer walls 213, 214 increases, and the load-bearing capacity of the vibration unit 210 can be improved.
  • the container 101 does not have to have outer walls 213, 214. That is, the container 101 may be composed of a plate-shaped upper container 101A having only a top plate 211 and a plate-shaped lower container 101B having only a bottom plate 212. This can further reduce the weight of the container 101 and improve vibration efficiency. In this case, the axial load of the vibrating body 102 applied to the container 101 is received by the vibrating body 102 itself mounted between the top plate 211 and the bottom plate 212. For this reason, it is preferable to provide multiple vibrating bodies 102 or to increase the rigidity of the housing of the vibrating body 102 itself.
  • the buffer member 103 is provided between the vibrating body 102 and the top plate 211 or bottom plate 212, but the buffer member 103 is not an essential component.
  • the buffer member 103 may not be interposed and the vibrating body 102 may be directly abutted against the top plate 211 or bottom plate 212. In this case, the vibration force is not reduced by the buffer member 103, so the vibration efficiency can be increased.
  • the vibrating body 102 was cylindrical, but it may be polygonal, such as rectangular.
  • the positioning portion 218 is polygonal, following the shape of the vibrating body 102.
  • multiple types of positioning portions 218 that match the outer shapes and dimensions of the vibrating bodies 102 may be provided in the upper container 101A and the lower container 101B.
  • a sensor that detects the load applied to the vibration unit 210 a sensor that detects the movement of the vibrating body 102, etc. may be provided.
  • a sensor that detects the load applied to the vibration unit 210 may be provided, and if the load exceeds the load capacity of the vibration unit 210, an alarm or the like may be issued to notify the user.
  • a and/or B is synonymous with “at least one of A and B.”
  • a and/or B means that it may be just A, or just B, or a combination of A and B.
  • the same idea as “A and/or B” is also applied when three or more things are expressed by linking them with “and/or.”

Abstract

Le problème décrit par l'invention concerne la fourniture d'un élément vibrant et d'un dispositif vibrant qui, malgré leur légèreté, ont des propriétés de support de charge et une efficacité vibratoire exceptionnelle. À cet effet, la présente invention comprend : une source de vibrations capable de générer des vibrations en réponse à des signaux audio reçus via une partie de réception ; une partie de transmission qui est un élément de fixation auquel la source de vibrations est attachée, la partie de transmission ayant la source de vibrations attachée à une de ses surfaces et supportant un utilisateur sur une autre surface, et dans cet état, transmettant les vibrations générées par la source de vibrations à l'utilisateur à travers l'autre surface ; une partie de support fournie à la source de vibrations sur le côté opposé à la partie de transmission ; et un boîtier dont au moins une partie est constituée de la partie de transmission et de la partie de support. La source de vibration vient en butée sur la partie de support et la partie de transmission. La source de vibrations supporte des charges exercées sur le boîtier.
