Abstract
A toy musical box having an electronic musical sound reproduction circuit and an electric motor drive for an endless band carrying a continuous picture past a window, so that the musical box can resemble a television set. The operation of the sound reproduction circuit and the motor are remotely controlled by sound impulses from a separate hand-held device, the musical box having a microphone and a discriminator to provide an output signal upon receipt of the sound impulses. Preferably a double sound impulse is acquired to operate the musical box, eg. two clicks one immediately following the other, for differentiation from other extraneous sounds.
