Abstract
Official abstract text for this publication.
A vibration system is disclosed. The vibration system includes a diaphragm and a voice coil that drives the diaphragm to vibrate. The diaphragm includes a fixing part for fixing the voice coil, and a heat sink is disposed on and fixed to the fixing part. A speaker using the vibration system is also disclosed. By disposing the heat sink on the diaphragm, heat can be dissipated from the voice coil effectively to ensure stability of the speaker.
