とにより発音体から前記周波数の音を発生させる
発音体駆動回路において、 前記発音体に所定時間以上継続して電流が流れ
る場合はこの発音体に流れる電流を強制的に断に
する手段 を具えたことを特徴とする発音体駆動回路。[Claims for Utility Model Registration] In a sounding body drive circuit that generates a sound at a frequency from a sounding body by cutting and disconnecting a current flowing through the sounding body at a predetermined frequency, the current continues to flow through the sounding body for a predetermined period of time or more. A sounding element drive circuit comprising means for forcibly cutting off the current flowing to the sounding element if the current flows.
