MOTOR ACTUATED BUZZER

摘要

A motor actuated buzzer includes a motor mounted on a body, at least one cam member fixedly mounted on an output shaft of the motor, a sound generating plate mounted on the body, and a hammer for striking the sound generating plate, the cam having a plurality of radial protrusions. At least one leaf spring is fixed to the body at one end thereof and urged toward the cam member. The leaf spring carries the hammer intermediate opposite ends thereof and having at a free end thereof a projection. The radial protrusions are engage able with the projection upon rotation of the cam member to oscillate the leaf spring to intermittently bring the hammer into striking contact with the sound generating plate to produce a buzzing sound.
