The transducer is received in a housing part (2) which includes fixing means for the transducer and its electrical connection means. The housing part is assembled with at least one other complementary part (1) in order to form the handset shell, and it closes the shell locally. An adaptor sleeve makes it possible to replace the piezoelectric transducer by an electromagnetic transducer.
