  • Toy vehicle with electronic sounder and direction sensor
    Patent number: 5045016
    Abstract: A toy wheeled vehicle such as a toy truck which is intended to be pushed along by a child includes electronic circuitry which is capable of emitting a plurality of different sounds similar to the sounds of a real truck. The actual sound of a truck's internal combustion engine is digitized and stored in a microprocessor along with other sounds such as those generated by a starter motor, horn, backup beeper and the like. In addition, the microprocessor is capable of synthesizing additional realistic vehicle sounds such as those generated by air brakes and the like. A starter switch first activates the starter motor sound and then the engine sound at idle speed. A speed sensor senses both speed and direction of travel and varies the engine sound in response to the sensed speed. The backup beeper sound is automatically generated along with the engine sound when the truck is moved in reverse. The microprocessor not only stores all of the digitized sounds but also controls all of the operations of the truck.
