| 摘要 |
There is provided a capacitor microphone comprising a capacitor transducer (KW), a high frequency bridge (HFB) coupled to the capacitor transducer (KW), a high frequency coil (HFS) coupled to the high frequency bridge (HFB), an HF transformer (HFT), a synchronous demodulator (SD), a low frequency output (NFA) and a high frequency stabilizer unit (SE). The high frequency stabilizer unit (SE) is coupled between the synchronous demodulator (SD) and the low frequency output (NFA) and serves to stabilize the HF voltage.
