ABSTRACT:
Disclosed is an actuator for a percussion instrument, such as a bass drum. The actuator includes a heel driven pedal, which handles the vertical motion of a free falling leg, and through the motion transmitting lever, which ends with a sound initiation member, transforms it onto the bass drum face until the heel driven pedal reaches a blocking surface of the actuator's base. The user can initiate the percussion instrument by letting his leg to fall down from a raised position while keeping the foot toe in one place on the base. The heel driven pedal, after it reaches the base, is blocked, what prevents from hitting the drum face with unnecessary big force and allows to control the dynamic of play so it does not increase with tempo. The base also allows the heel driven pedal to have a surface from which it can rebound and return to pre-shot position. The motion transmitting lever transmits motion of a heel into motion of a sound initiation member as well as regulates the maximum deflection of the beater into the bass drum face and by this means controls the dynamic of play. The actuator also allows to filter weak shots, which for some reason may not be desired.
