Abstract

PURPOSE:To prevent degradation of signal information, by storing a vibration- voltage converter and an A-D converter in a microphone case and by taking out an digital output as a microphone output. CONSTITUTION:The acoustic wave is converted to an analogue electric signal by vibration-electric converter 2 in microphone case 1 and is amplified by amplifier 3. The amplified analogue electric signgal is converted to a digital signal by A-D converter 4 and is output through cable 6 to external.
