Abstract

La présente invention concerne un dispositif de rétroaction de force, un appareil électronique l'utilisant, et un système d'appareil électronique. Le dispositif de rétroaction de force comprend une base, une gâchette, un mécanisme à cliquet et un mécanisme de pression ; la gâchette est reliée de manière rotative à la base, et a une position initiale et une position inférieure ; le mécanisme à cliquet comprend un cliquet, un cliquet actif et un cliquet de retenue ; le cliquet est monté sur la base et situé sur le côté interne de la gâchette ; le cliquet actif est monté sur la surface latérale interne de la gâchette et utilisé pour venir en prise avec le cliquet lorsque la gâchette est abaissée ; le cliquet de retenue est en prise avec le cliquet ; le mécanisme de pression est monté sur la base, relié élastiquement au cliquet de retenue, et utilisé pour presser le cliquet de retenue sur le cliquet. La présente invention peut fournir une meilleure expérience de rétroaction tactile pour un utilisateur.
