Patent number: 11640142Abstract: 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 f0 of a first vibration mode.Type: GrantFiled: October 10, 2019Date of Patent: May 2, 2023Assignee: Blancpain SAInventors: Alain Delizee, Mehdi Denden, Jerome Favre
