  • two piezoelectric diaphragms each corresponding to a force S stereo RL audio signal, are affixed to the violin torso, it becomes more difficult to hear and a harsh distortion sound is emitted.

Abstract

La présente invention concerne une partie vibrante ayant deux plaques vibrantes piézoélectriques pouvant vibrer du fait d'un signal sonore stéréo et fixée dans une position supportée par le pont par le biais d'une structure. Un signal sonore stéréo est entré dans la partie vibrante pour faire vibrer de façon stéréophonique le pont par le biais de la structure. La plaque avant, le billet audio, la barre d'harmonie et la plaque arrière vibrent donc systématiquement de la même façon que la vibration de corde normale, et le violon peut donc par conséquent être actionné automatiquement. Lorsqu'un signal sonore stéréo est entré dans la partie vibrante, il est donc facile de réaliser l'interprétation automatique de la source sonore stéréo.
