ABSTRACT:
A toy vehicle incorporating a sound effect generator similar to an acoustical phonograph having a machined turntable with mutually exclusive sound tracks, each of the sound tracks creating a different sound effect through a tone arm and speaker cone arrangement. The turntable is driven by a gear train from the wheels of the vehicle. Selection of the various sound effects is made by movement of the vehicle in response to the normal forces of the play pattern on the vehicle causing the tone arm to engage different ones of the sound tracks.
