A watch () has a microphone () placed in a watchcase (), a bracelet () with two end parts respectively attached to two opposite sides of the case and at least one through aperture () made in a lateral wall () of the case. The through aperture defines a first sound wave guide channel, and opens into the case in the direction of said microphone. The microphone is connected in the case to a sound wave processing unit circuit () for voice recognition. The watch further includes an audio guide member () fitted with a second open sound wave guide channel that comes into direct contact with the external surface of the lateral wall of the case across an area () that extends on either side of the aperture so as to guide the sound waves towards said first channel. This guide member may be made in an end part of the bracelet. In this manner, any interference from reflecting cavities, edges or surfaces in said area close to the aperture can be removed or attenuated.

Watch including a built-in microphone in the watchcase

The present invention concerns a water-resistant portable apparatus including a case in which there is mounted an electroacoustic transducer separated from an inlet cavity in a water-resistant manner by a deformable membrane. This inlet cavity is arranged in said case in direct communication with the exterior. The electroacoustic transducer and the inlet cavity are arranged collaterally such that at least one part of said transducer, respectively of the cavity, of a determined thickness is arranged in the same slice of the case and in that an acoustic channel connects the transducer to the membrane to transmit acoustic vibrations.

Water-resistant portable apparatus comprising an electroacoustic transducer

The device for implanting a microphone () and at least one pressure compensating member () in a telephone watch consists in placing the microphone and the compensating member close together. A membrane () covers the microphone () and a disc () forms the compensating member (). The membrane () and the disc () open at least partially into a single chamber () opening onto the outside via an opening () 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.

A device includes a case (,) in which an acoustic transducer (,) is mounted so as to communicate in a water tight manner with the exterior of the case (,) via acoustic energy. The transducer (,) is mounted in front of a membrane (,) able to be deformed separating it in a water tight manner from an inlet cavity (,) which is arranged in the case (,) of the device and is in communication with the exterior. Between the membrane (,) and the transducer (,) an intermediate chamber (,) is arranged allowing deformation of the membrane by the action of external static pressure and delimited on the side of the transducer by a support element (,) fixedly mounted in the case and capable of limiting the deformation of the membrane in the event of application of the external pressure.

Device capable of being submerged and including an acoustic transducer

A case (2) in which an acoustic transducer (22) is mounted so as to communicate in a watertight manner with the exterior of the case (2) via acoustic energy. The transducer (22) is attached to a membrane (17) separating it in a watertight manner from an inlet cavity (10, 11) which is arranged in the case (2) and is in direct communication with the exterior. The membrane (17) is resiliently applied by its periphery onto a rest surface (12) arranged around the cavity separating the latter in a watertight manner from a deformation chamber (13) situated on the side of the membrane (17) opposite to the inlet cavity while being in communication with the interior of the case. The bottom (13a) of the deformation chamber (13) forms a support surface for said membrane (17) when external static pressure greater than a predetermined value is applied thereto.
