Abstract

Telephone handset equipped with at least one piezoelectric transducer (6, 7). This transducer is housed in a part (2) which contains means of fixing this transducer and its electrical connection means. This part is assembled with at least one other complementary part (1) in order to form the shell of the handset, which it closes locally. An adaptor sleeve optionally enables the piezoelectric transducer to be replaced with an electromagnetic transducer. <IMAGE>
