Abstract: In a device (8) which includes an electroacoustic transducer (7) for the acoustic reproduction of sound signals to an ear (14) of a user (2) who assumes a user position at the device (8), the transducer (7) is optimized for the acoustic reproduction of speech-signal sound waves and is equipped with additional means (25) for realizing a distinct directivity for the speech-signal sound waves emitted by said transducer (7) and, as a result of its directivity, the transducer (7) directs the speech-signal sound waves which it emits preferentially to the ear (14) of a user (2) who is in the user posture.
