Abstract
A sound effect device for radio controllable toy vehicles is capable of producing various realistic sounds such as a klaxon horn, an emergency braking sound, a small braking sound, and a tire-squealing sound upon sharp turning. The sounds are generated depending upon the driving condition of the toy vehicle, and the device is further capable of producing realistic sounds that are readily modified various types of toy vehicles. The device may have an engine sound on/off switch and a starting switch that causes production of a first engine sound which is thereafter varied based on the driving condition of the vehicle. Further, the device may generate certain sounds only upon simultaneous detection of two signals controlling the movements of the vehicle.
