Abstract:
    A voice circuit is arranged on a chassis member. The voice circuit includes a voice outputting amplifier and a high-frequency bypass part. An output terminal of the voice outputting amplifier is connected to one edge of a voice coil through wiring and is grounded through the high-frequency bypass part. The voice outputting amplifier supplies the voice coil with a voice current through the wiring. The resonance frequency of the high-frequency bypass part is set at the same frequency as that of a discharge current flowing in the chassis member. A high-frequency induction current generated in the voice circuit due to the discharge current flowing in the chassis member is permitted to flow into a grounding terminal through the high-frequency bypass part.
