A rotating mallet assembly for generating a continuous note from a standing bell includes a base, which is positionable on a substantially horizontal surface. A fastener engaged to an upper surface of the base can selectively engage a bottom of a standing bell so that the standing bell is removably engaged to the base. An arm is engaged to and extends from the base. A mallet is pivotally engaged to and extends from the arm distal from the base so that the mallet frictionally contacts a rim of the standing bell. A motor is engaged to the arm and is operationally engaged to the mallet. The motor is positioned to selectively rotate the mallet relative to the standing bell to excite continuous vibrations in the standing bell so that a continuous note is produced.

A light-powered, electromechanical chime has a striker assembly (3) inside a bell (1). The striker assembly contains a clapper (6) and electronics, including a light collector (7) and a motor (10.) The striker assembly is suspended by a torsion element (2) attached to the shaft (11) of the motor. Light causes the motor to wind the torsion element, then the unwinding torsion element causes the striker assembly to rotate and the clapper to strike the bell.

In some embodiments, a power supply in a doorbell system includes a boost rectifier circuit with a plurality of active devices arranged in a bridge topology that are configured to receive an AC input voltage, generate a DC output voltage by rectifying the AC input voltage, drive an electric load using the rectified DC voltage, and boost an amplitude of the AC input voltage. Two of the plurality of active devices in the boost rectifier circuit may be pulse driven and can control an operation of a mechanical or digital chime device. The chime device can include a solenoid and the boost rectifier circuit may utilize the solenoid as an energy storage element to facilitate the boosting of the amplitude of the AC input voltage. The boost rectifier circuit may boost the AC input voltage by at least a multiplication factor of two.
