AI Technical Summary

Technical Problem

Mechanical watches have complex and bulky striking mechanisms with limited energy and autonomy, while electronic watches produce synthetic sounds that lack the natural timbre of mechanical gongs, making it difficult to achieve a compact and efficient alarm or minute repeater system in watches.

Method used

A hybrid watch mechanism combining mechanical gongs with an electrodynamic actuator driven by an integrated circuit and electrical energy accumulator, allowing for a compact, high-energy, and uniform striking system that produces natural sounds, with optional pre-oscillations to enhance impact energy.

Benefits of technology

The solution provides increased autonomy, sound intensity, and spatial efficiency, while generating natural sounds comparable to mechanical gongs, exceeding the energy of electronic systems with optimized current pulses and pre-oscillation techniques.

Abstract

A watch according to the invention comprises a striking mechanism, including at least one fixed gong (4) and at least one hammer (15), as well as a battery (6) and an integrated circuit (7) powered by the battery and configured to produce current pulses, and an electrodynamic actuator (17) connected to the integrated circuit and capable of receiving said pulses, the actuator being integral with the hammer or connected to the hammer so as to generate, in response to said pulses, a movement of the hammer from its rest position, said movement being capable of striking the gong with the hammer. The mechanism also includes a spring (27) connected to the hammer so as to return the hammer to its rest position after the impact. In particular embodiments, the hammer undergoes one or more pre-oscillations before striking. In one particular embodiment, the hammer and the gong are provided with attracting magnets.
