STRIKING OR MUSICAL WATCH PROVIDED WITH AT LEAST ONE ACOUSTIC RADIATING MEMBRANE AND METHOD FOR MANUFACTURING THE MEMBRANE
20200133202 · 2020-04-30 · ·

A striking watch is provided with an acoustic radiating membrane made of metallic material or amorphous metal. The membrane takes the form of a loop with walls of a certain thickness to be connected by a first edge portion to a middle part of a watch case and by a second edge portion to a bezel fixed to a watch crystal. The bezel connected to crystal is movable with respect to the case middle via the membrane during the vibration of membrane once a sound is generated by a watch striking mechanism in the watch case. The membrane is configured with a wall of a specific thickness in an active region dependent on the mass of the bezel connected to the crystal, to obtain a frequency f.sub.0 of a first vibration mode.

Atypical gong, watch with striking mechanism comprising the same and gong manufacturing method

The gong is made with a wire or a strip having an atypical shape for a watch striking mechanism. The gong includes a rectilinear part connected to a curved part. The rectilinear part and/or the curved part are connected to the same gong-carrier. The gong includes several notches made at defined geometric points on a portion of the length of the gong to adapt the natural vibration frequencies within an audible range between 1 kHz and 5 kHz, so that the sound produced by the vibrating gong is harmonious.
