Patent ID: 8477981

Claim:
A watch comprising: (a) a watchcase; (b) a sound wave processing unit circuit; (c) at least one microphone connected to the sound wave processing unit wherein the microphone and the sound wave processing unit circuit are placed inside the watchcase; (d) a bracelet having two end parts, respectively attached to two opposite sides of the watchcase; (e) at least one through aperture made in a lateral wall of the watchcase, wherein the aperture defines a first sound wave guide channel, wherein the through aperture opens into the case in the direction of the microphone, for the reception of sound waves by the microphone; and (f) an audio guide member fitted with a second open sound wave guide channel, wherein the audio guide member is made in one of the end parts of the bracelet, and comes into direct contact with an external surface of the lateral wall of the case, across an area that extends on either side of the aperture, to guide the sound waves towards the first channel, so as to remove or attenuate any interference from reflecting cavities, edges or surfaces in an area close to the aperture; wherein the a contact line of the second sound wave guide channel with the external surface of the lateral wall is U-shaped; and wherein the base of the U defines an arc of a circle that is centred relative to the through aperture for receiving sound waves, or relative to a group of through apertures made in the lateral wall.
