Abstract
A musical toy has a simple construction and can accurately produce melodies and rhythms without also producing extraneous mechanical noise. A generally doll-shaped body contains two permanent magnets and is fitted with a pair of swinging members each containing an electromagnetic coil disposed so that it faces the permanent magnets. A control device, containing a rhythm signal generator circuit and a control circuit which creates rhythm drive signals based on the signal from the rhythm signal generator circuit, supplies each of the coils with a separate and independent drive signal. A sound producing body is disposed in the swinging path of each swinging member so that when the swinging member is caused by the magnetic interaction between the coil and the permanent magnets to swing in response to the rhythm signal from the control device, the sound producing body is struck by the swinging member and a musical note is sounded.
