This vibration is transmitted to the body and the speaker, and the resonant cavity resonance effect is produced in the well-designed speaker, thus forming a special tone of the stringed instrument.

Abstract

Un système de reproduction de son comprend un instrument à cordes (60), une tête de lecture (30) montée sur l'instrument à cordes, un dispositif d'enregistrement et de reproduction de son (908) se connectant électriquement à la tête de lecture, un amplificateur (404) se connectant électriquement au dispositif d'enregistrement et de reproduction de son, un actionneur (20) et un corps résonant (50). Le son est détecté et converti en un signal de sortie audio par la tête de lecture (30). Le signal de sortie audio est enregistré et reproduit par le dispositif d'enregistrement et de reproduction de son (908) qui délivre un signal d'entrée audio. Le signal d'entrée audio est amplifié par l'amplificateur (404) pour produire un signal d'entrée audio amplifié. Une vibration mécanique est générée par l'actionneur (20) monté sur le corps résonant conformément au signal d'entrée audio amplifié. Sur la base de la vibration mécanique, une résonance est produite par le corps résonant (50), qui sert de dispositif de sortie de son pour produire un son.
