System and method for controlling electrical current flow as a function of detected sound volume

An assembly comprising:

• a variable speed motor capable of rotating at different speeds, wherein the rotational speed of said motor depends upon current supplied to said motor;
• a vehicle propelled by said variable speed motor, wherein said vehicle travels at a speed dependent upon said rotational speed of said motor;
• an audio detector for detecting the volume of sound energy at a particular location and producing an electrical signal corresponding to the volume of sound energy;
• a current flow controller for selectively controlling current flow to said motor as a function of said electrical signal, wherein the louder the volume of sound received by said audio detector, the more current said current flow controller directs to said variable speed motor and the faster said variable speed motor rotates.

A method of controlling the rotating speed of a variable speed motor used to power a toy vehicle, said method comprising the steps of:

• converting sound energy into a corresponding electrical signal, wherein said electrical signal varies with the volume of the sound energy;
• utilizing said electrical signal to selectively adjust a current flow controller, wherein said current flow controller enables the flow of current in a manner proportional to the volume of sound energy represented by said electrical signal;
• and
• directing current through said current flow controller to said variable speed motor, wherein the louder the sound energy received, the more current said current flow controller directs to said variable speed motor, the faster said variable speed motor rotates and the faster said toy vehicle travels.
