Speaker apparatus and method for driving speaker |
摘要 |
A speaker apparatus includes an acoustic vibration plate, and an actuator mounted to the acoustic vibration plate such that one end and the other end thereof, in a driving axis direction, exist in a plate surface of the acoustic vibration plate. The actuator applies vibration to the acoustic vibration plate to play back sound. The speaker apparatus enables a sound image to uniformly spread over the entire plate surface of the acoustic vibration plate. In addition, the entire speaker apparatus can be made compact. |
