    • A digital type electroacoustic transducer converts between a digital electric signal and an analog acoustic signal and includes units A (sounding bodies) arranged on the same plane as that of units B (sound receiving sensors), with the number of group units being decided at a ratio corresponding to a digit position of each bit of the digital signal. When the bit exists, a power source for electrode driving and the group unit are connected, and both of an electric/acoustic conversion and a digital/analog conversion are simultaneously executed through the unit A. The units B provide an addition value of all outputs of the units A. After a level of the detection acoustic signal is adjusted by a preamplifier, the signal is delta modulated and supplied to an arithmetic operating circuit. When a digital electric signal which is input does not exist, only the acoustic signal which arrives at the diaphragm surface of the unit B is input to the arithmetic operating circuit. A digital signal proportional to the acoustic signal is derived from a digital type electroacoustic transducer output terminal.
