Abstract

A remote control toy has a main housing and a remote housing. A radio receiver is located in the main housing for receiving transmitted radio signals. The main housing includes a plurality of elements moveably mounted thereon which are set in motion by a motor in response to receipt of transmitted radio signals by the radio receiver. The remote housing incorporates a radio transmitter. The transmitter includes an electrical circuit having an antenna, a piezoelectric element for generating a current and an electrical component which is capable of generating a radio frequency signal in response to current flow through the electrical circuit. The remote housing further includes a moving member which is moved by the operator of the toy. The moving member is associated with the piezoelectric element to impact a mechanical force on the piezoelectric element for generation of an electrical current in the electrical circuit.
