Abstract
The present invention concerns a water-resistant portable apparatus including a case in which there is mounted an electroacoustic transducer separated from an inlet cavity in a water-resistant manner by a deformable membrane. This inlet cavity is arranged in said case in direct communication with the exterior. The electroacoustic transducer and the inlet cavity are arranged collaterally such that at least one part of said transducer, respectively of the cavity, of a determined thickness is arranged in the same slice of the case and in that an acoustic channel connects the transducer to the membrane to transmit acoustic vibrations.
