MULTI-FUNCTION ACTUATOR HAVING FUNCTION OF PREVENTING VIBRATION GENERATION

摘要

The actuator (1) has a moving coil (22) vibrating a diaphragm (21) in response to an audio signal, where the diaphragm generates sound. A vibratory coil (33) generates a vibration in response to an audio or vibratory signal. The coils apply electromagnetic forces on a vibratory unit (30), where the forces become coaxial and opposed to each other in order to be cancelled when the audio signal is applied simultaneously to the coils.
