  • Such a timepiece is for example a striking watch (such as a minute repeater, grand strike, small strike, alarm clock) for which the vibration-generating device is for example a gong arranged to be struck by a hammer when the buzzer is engaged to generate vibrations to produce sound.
  • the gong is conventionally in the form of a leaf spring wrapped around the movement.
  • the gong is mounted integral with the frame (assembly of the plate and the bridges) of the watch by means of a heel or gong holder, in order to transmit the vibrations of the gong to the whole of the watch (frame, movement , trim components).
  • the vibrations of the gong are transmitted to the wearer of the watch with maximum intensity.
  • the document DE 14 58 431 describes a striking clock comprising a gong mounted on a heel and a resonating plate. Said plate is joined at one end to the heel of the gong, and is fixed at the other end to the wall of the clock case, leaving a space between the resonance plate and said wall. The heel cooperates with the gong to vibrate with said gong and transmit the vibrations of the gong to the plate.
