Voice-operated control circuit and method for using same

摘要

A voice-operated control circuit and method for using the voice-operated control circuit in connection with a toy vehicle. The voice-operated control circuit contains an audio detector, such as a microphone, to detect audible sound signals, and an integrated circuit that determines the duration of the audible sound signals received by the audio detector. At a user-defined time and based on the audible sound signals received, the integrated circuit determines and controls the duration of operation of various components of the toy vehicle, such as a motor, lights and/or sounds.

主权项

1. A voice-operated control circuit for a toy vehicle comprising:
an audio detector circuit for receiving audible sound signals; a switch having an open position and a closed position; a motor; and an integrated circuit coupled to the audio detector circuit, said integrated circuit configured to determine, from when said switch is in its open position to when said switch is in its closed position, the cumulative duration in which audible sound signals greater than a predetermined decibel level are received by said audio detector circuit, to calculate a period based on said cumulative duration, and to provide output signals to activate said motor for said period.
