A new type of microphone is proposed, one of the distinguishing features of which is a variable sensitivity, which depends on the magnitude of the constant electric pumping voltage. In addition, a matching device (mediator) has been created that allows to significantly increase the sensitivity of the microphone. In the course of experiments, a significant increase in sensitivity was confirmed, both due to a charge pump and the use of a mediator. In the course of the experiments, the microphone sensitivity was obtained equal to 1990.5 mV / Pa at 1000 V pumping.
