| 摘要 |
The device (10) has a casing (12) accommodating a sound pick-up microphone sensor (14), a sound reproduction transducer (16), control buttons (18, 20, 22, 24), a printed board, a power battery, operation indicators (26, 28), an external connector, and a near-field communication antenna. The casing is in the form of a U-shaped clamp having two branches (32, 34) separated by a transverse discontinuity (36). The transducer is carried by one branch, and the sensor is carried by the other branch, so that the transducer and the sensor are acoustically decoupled by the transverse discontinuity. |
