Abstract
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.
Claims19
A gong for a striking mechanism of a watch, the gong comprising:
- a wire or a strip including a rectilinear part connected to a curved part;
- and
- at least two notches or hollows or grooves at defined geometric points on a portion of a length thereof so as to adapt at least two natural vibration frequencies within an audible range between 1 kHz and 5 kHz, the notches or hollows or grooves formed on an undersurface of the gong such that the at least two notches or hollows or grooves are not visible on an upper surface of the gong located opposite the undersurface,
- wherein a ratio between the at least two frequencies is a number N+d, where N is an integer number greater than or equal to 2, and d/N is comprised between −0.01 and +0.01, so that a sound produced by the gong results in consonant harmonic and melodic intervals.
