Abstract
A toy vehicle with noisemaker includes a closed rectangular resonating chamber with a hard flexible diaphragm forming the upper chamber surface. An idler wheel in the gear train between the vehicle's electric motor and the driven rear wheels has cam profiles molded in its flat surface. A hammer pin extending through a rigid chamber wall rides on the cam profiles and continuously and alternately flexes and releases the diaphragm. When released, the diaphragm unflexes and drives against a rigid stop. The impact of the hard diaphragm against the stop oscillates the diaphragm and causes a sound which the resonating chamber amplifies. The sound is produced twice with each revolution of the idler wheel.
