VIBRATING ELEMENT

摘要

A vibrating element including a diaphragm, a voice coil and a stiffening layer is provided. The diaphragm has a first surface and a second surface opposite to each other. The first surface includes a first conductive region and a second conductive region. The voice coil is disposed on the first surface. Two ends of the voice coil are electrically connected to the first conductive region and the second conductive region. The stiffening layer is disposed on the diaphragm. The diaphragm has a center region, which is enclosed and circled by the voice coil and includes an area of the diaphragm above the voice coil. The region outside the center region includes an inner circled zone and an outer circled zone surrounding the inner circled zone. At least one end of the voice coil is located in the inner circled zone and the stiffening layer covers the inner circled zone.
