Mobile terminal with electromagnetic actuator |
摘要 |
This invention deals with a portable terminal that reduces extraneous tones in a portable terminal in which is mounted an electromagnetic induction actuator that produces voice signals, a buzzer signal or a low frequency vibration. By short-circuiting the terminal fittings of the electromagnetic induction actuator or by connecting them electrically to amplifiers or to a signal generator that produces a constant voltage signal or a constant-frequency signal, the extraneous tone produced by vibration of the mechanical vibration system of the actuator is reduced.
