Abstract
A multifunctional vibrator includes a frame, a vibrating unit receiving in the frame and including a magnetic circuit part with a magnetic gap, a plurality of elastic members connecting the vibrating unit and the frame, and a voice coil partially inserted into the magnetic gap. Each elastic member includes a retaining portion assembling to an inner face of the frame, a connecting portion attached to the vibrating unit, and an elastic portion extending from the retaining portion to the connecting portion along a devious way. The elastic portion of elastic members includes a first arm capable of generating elastic deformation along a short axis direction of the vibrating unit and a second arm capable of generating elastic deformation along a long axis direction of the vibrating unit.
