Abstract
The piezo-electric device (9) which connects a glass (8) to a movement (3) of the timepiece (1) is arranged in such a way as to deform in flexion in response to an exciting signal applied to its electrodes. The attachment zones (9a,9b) of this device (9) to this glass (8) and respectively to this movement (3) are distinct one from the other when the timepiece (1) is looked at in a direction perpendicular to the planes of the principal faces of the device (9). Thanks to this arrangement, the sound produced by the displacement of the glass (8) when the exciting signal is applied to the electrodes of the piezo-electric device (9) is more intense than in a known timepiece.
