Abstract
An audio resonance vibrator includes a yoke defining a bottom and a sidewall extending vertically from the bottom, an elastic frame cooperatively with the yoke forming a housing defining a receiving space, a magnet disposed on the bottom of the yoke cooperatively with the sidewall of yoke forming a magnetic gap, a vibrating unit accommodated in the receiving space defining a vibrating plate and a coil assembly connected with the vibrating plate. The coil assembly is at least partially received in the magnetic gap, and the vibrating plate is positioned on the elastic frame. The audio resonance vibrator further includes an elastic member interposed between the magnet and the vibrating plate to support the magnet.
