Device for implanting a microphone and a pressure compensating member in a telephone watch
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.
1. A telephone watch comprising:
a case having a cavity;
a microphone, having a front face and a rear face, mounted in said case so that said rear face faces said cavity; and
at least a first pressure-compensating member having a front face and a rear face, said rear face of said at least first pressure-compensating member facing said cavity,
wherein said front face of the microphone is covered with an impermeable membrane,
wherein said first pressure-compensating member includes a hydrophobic disc, said impermeable membrane and said hydrophobic disc being in direct communication with an exterior of the case,
wherein said microphone and said a least first pressure-compensating member are arranged in immediate proximity to each other, and
wherein said impermeable membrane and said hydrophobic disc open at least partially into a single chamber opening out to an outside of the telephone watch through a long opening in said case.
2. The telephone watch according to claim 1 , wherein the opening has a slot with elongated edges connected to each other by a reinforcing rib located substantially in the middle of the slot.
3. The telephone watch according to claim 1 , wherein the disc fitted to the first pressure-compensating member is impervious to liquids, and permeable to gases whose pressure varies slowly.
4. The telephone watch according to claim 1 , wherein the membrane covering the microphone defines therewith a space in communication with a second pressure-compensating member including a disc which is permeable to gases whose pressure varies slowly.
5. The telephone watch according to claim 1 , wherein said opening is a slot having a length sufficient to allow circulation of a cleaning fluid, said circulation defining a cleaning flow.
