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.
Claims14
A device,
- in which a user can assume a user posture and
- which comprises a carrier for carrying at least one electroacoustic transducer, which carrier is made of an acoustically dense material and extends comparatively close to at least one ear of a user who is in the user posture, to which carrier an electroacoustic transducer is attached for the acoustic reproduction of sound signals for an ear of a user who is in the user posture, which transducer comprises sound-generation means for generating and emitting sound waves,
- characterized in that
- the transducer is constructed for an optimum acoustic reproduction of speech-signal sound waves and
- the transducer is equipped with additional means for realizing a distinct directivity for the speech-signal sound waves emitted by said transducer and,
- as a result of its directivity, the transducer directs the speech-signal sound waves which it emits preferentially to an ear of a user who is in the user posture.
