    • PROBLEM TO BE SOLVED: To maintain a vibration application function of a vibration application device, to an object to be vibrated, even when a dimension change of the object to be vibrated is caused in a direction with which a vibration direction of a movable body of the vibration application device intersects.SOLUTION: A movable body 100 of a vibration application device 50 includes an electromagnetic engagement part EM and a rod-like part 101. When a drive signal is input to a voice coil 513, the electromagnetic engagement part EM is vibrated by a magnetic path formation part 52 which forms a magnetic path so that the movable body 100 is vibrated in a direction Z. An another end connection part 110 fixedly connects an another end part 101b of the rod-like part 101 to a sound board 7 so as to transmit a vibration of the movable body 100 to the sound board 7. An electromagnetic engagement between the magnetic path formation part 52 and the electromagnetic engagement part EM is maintained by providing a displacement allowing mechanism at least in one of a fixing part for fixing the magnetic path formation part 52 to a vertical column, the movable body 100, and the another end part connection part 110 even when the another end connection part 110 displaces in a horizontal direction within a prescribed range relative to the vertical column, and the vibration of the movable body 100 is transmitted to the sound board 7.
    • 要解决的问题:为了将振动施加装置的振动施加功能保持在要振动的对象上,即使当使振动对象的振动方向发生振动的方向时, 振动施加装置相交。解决方案:振动施加装置50的移动体100包括电磁接合部EM和杆状部101.当将驱动信号输入到音圈513时,电磁接合部EM为 由形成磁路的磁路形成部52振动,使得可动体100沿Z方向振动。另一端连接部110将棒状部101的另一端部101b固定在声音板 以便将可移动体100的振动传递到声音板7.磁路形成部52与电磁接合部EM之间的电磁接合保持 通过在至少一个用于将磁路形成部分52固定到垂直柱,可移动体100和另一端部连接部分110的固定部分中的一个中设置位移允许机构,即使当另一个端部连接部分110移位时 在相对于垂直列的规定范围内的水平方向上,将可动体100的振动传递到声音板7。
