Abstract

La présente invention concerne un système pour engendrer la commande directe d'une vibration forcée avec un ressort d'accélération, qui utilise le mouvement linéaire d'un piston alternatif de moteur (1) pour commander une bobine (7) ou un aimant (9) et produire de l'électricité. Un ressort spiral (8) d'un système vibrateur principal comprenant le piston (1), la bobine génératrice (7), le ressort spiral (8) et un connecteur (2) est connecté au ressort d'accélération (13) avec un coefficient élastique élevé au point mort bas du piston, de sorte qu'ils puissent former un ressort de compression avec un coefficient élastique variable près du point mort bas. Un ressort spiral (15) est placé entre un ressort d'équilibrage et le système vibrateur principal, de sorte qu'ils puissent former un ressort avec un coefficient élastique variable près du point mort haut. Après que les ressorts d'accélération ont été connectés au système vibrateur principal, leur fréquence de vibration est compatible avec la fréquence de vibration principale, et leurs phases sont en harmonie, de sorte que la vibration et le bruit peuvent être réduits.
