Abstract
A light projecting toy musical box projects a light pattern which is synchronized with musical sound generated by an acoustic mechanism. The projected light patterns are formed by providing a lamp within a base and rotatably mounting a dome over the lamp and substantially on top of the base. The dome is made out of translucent material which is patterned with a semi-opaque coating so as to form light patterns on the dome itself and project the light patterns on adjacent ceilings and/or walls of a room.

A light projecting toy musical box comprising:
- a base;
- a dome movably mounted on the base and being substantially translucent;
- a lamp disposed within the base and projecting light through the dome;
- an acoustic mechanism, disposed within the base, for generating musical sound;
