Sound Module With 100+ Songs

Hour & Quarter-Hour Chimes

Play music on the hour or every quarter hour, or switch to classic chime styles: Shelf, Grandfather, Cuckoo, Train, and more.

Speaker & Volume Control

A clear, sealed-enclosure speaker paired with a single knob sub-board for play and volume, connected by ribbon cable for easy mounting.

Quartz Clock Movement

A standard quartz movement with hand shaft is included, ready to drive the hour and minute hands on your own clock face. The movement uses 1 AA battery.

Battery Powered

Runs on a battery holder included in the kit — we now use a class-D speaker amplifier for improved battery efficiency. The module uses 4 C batteries.

The speaker mounted in an enclosure in the frame at the bottom of the clock
The speaker mounts in the frame at the bottom of the clock, which needs about 2½ inches of frame depth. An enclosure like the one shown can be used, but it also works without one — any speaker or speaker system can be used.
The volume and play knob mounted in the side frame of the clock
The volume/play knob mounted in the clock's frame, with a small hole for the day/night sensor above the knob.
