Abstract (en)
[origin: EP2026596A1] The sound transducer includes a sound insulator (15) that encompasses a pressure-voltage transducer (12). The pressure-voltage transducer is in connection with a supporting plate (14) for resting in contact on the body part. The supporting plate has a larger surface area than the pressure voltage transducer.
