    • A switching device for generating an electrical switching signal for a hearing aid circuitry is provided having improved actuating comfort for users of hearing aids and is adequate for a high degree of miniaturization. This switching device comprises a first piezoelectric element (7) excited by an electrical oscillator and generating mechanical oscillations transmitted via mechanical oscillation transmission means (10) to a second piezoelectric element (8) which, in turn, generates electrical oscillations from which the electrical switching signal is derived by processing means, preferably, after comparison with a threshold value. The mechanical oscillation transmission characteristic of the mechanical oscillation transmission means are modulated by modulating means (14) dependent from a mechanical input from the respective user of the hearing aid.
    • 提供了一种用于产生用于助听器电路的电切换信号的开关装置,其具有对于助听器的使用者具有改进的致动舒适性并且足以用于高度的小型化。 该开关装置包括由电振荡器激励的第一压电元件(7),并且产生经由机械振荡传输装置(10)传递到第二压电元件(8)的机械振荡,第二压电元件(8)又产生电振荡,电开关 信号是通过处理手段得到的,最好是与阈值进行比较。 机械振动传递装置的机械振动传播特性由调制装置(14)调制,该调制装置(14)取决于来自助听器的相应使用者的机械输入。
