Abstract
The present invention relates to a microphone comprising a transducer for converting acoustic or vibratory oscillations into an electric signal; a preamplifier for amplifying the electric signal; and a controllable switch arranged electrically between the transducer and the preamplifier, the switch being adapted to be controlled by a control signal, the preamplifier including an input terminal connected directly to a terminal of the transducer, the microphone being adapted to transmit the amplified electric signal to a power and transmission device. The invention further relates to a mask comprising such a microphone.
