Abstract
The device for implanting a microphone (1) and at least one pressure compensating member (2) in a telephone watch consists in placing the microphone and the compensating member close together. A membrane (5) covers the microphone (1) and a disc (6) forms the compensating member (2). The membrane (5) and the disc (6) open at least partially into a single chamber (7) opening onto the outside via an opening (8) in the form of a slot. A liquid (arrow A) can be injected through this slot to rid the chamber, the membrane and the disc of foreign bodies which could accumulate therein.
