ABSTRACT:
Transducer substantially comprising a hollow housing, a device located inside the hollow housing to transform the electrical signals output by a vibration pickup microphone, a generally discoid shaped element for acoustical coupling with the mastoid bone, having one face directed to the outside of the housing and one face arranged onto the inside of the housing itself, and a coupling element for connection between the vibrating unit and the acoustic coupling element. The acoustic coupling element comprises one soft material headset apt to close and seal one opening made on one face of the hollow housing, and to hold the vibrating element freely hanging into said housing, by means of the coupling element.
