PURPOSE: A vibration speaker is provided to steadily maintain coupling strength between an elastic member and a yoke by adjusting the junction location of an elastic member and a yoke into a boundary part. CONSTITUTION: A vibration speaker(1) elementarily includes a yoke(34), an oscillating element(30), and an oscillating plate(50). A magnet(32), which is offered in a case(10), is arranged in the yoke. The oscillating element includes an elastic plate(36) which is connected between the yoke and the case. The oscillating plate is arranged on the oscillating element in the case. The yoke and the elastic plate of the oscillating element are bonded in a boundary part. The oscillating element offers a vibration generating function. The oscillating plate offers a sound generating function. A weight is arranged in the yoke between the elastic plate and performs the role of amplifying vibration amount. |
