Super sound engine/transmission sound enhancer
First Claim
1. An electronic supercharger/transmission/engine sound duplicator simulator in combination with an internal combustion motor, a battery, and an alternator comprising:
- A) a motor rpm sensor electrically connected to said alternator for converting motor rpm to an electronic signal;
B) sound duplicator microprocessor and amplifier means electrically connected to the positive terminal of said battery to receive electrical power and to said rpm sensor to receive said electronic signal for converting the rpm electronic signal into a frequency modulated electric signal based solely on said rpm signal;
C) speaker means for receiving the frequency modulated electric signal for generating a sound which simulates that of a predetermined high performance vehicle, said microprocessor and amplifier means having replaceable microchips for selecting the high performance vehicle whose sound is to be simulated;
D) sound trim adjuster means electrically connected to said microprocessor and amplifier means for preventing the frequency modulated electrical signal from being transmitted to said speaker means when there is a predetermined low motor rpm; and
E) switch means adapted to be mounted on the dashboard of a vehicle containing said simulator for turning off power to said microprocessor and amplifier means.

Abstract
The present invention relates to an electronic engine sound duplicator simulator used in combination with an internal combustion motor, a battery, and an alternator. The sound duplicator simulator includes a motor rpm sensor, a sound duplicator microprocessor, an amplifier, a sound trim adjuster and a switch. When the internal combustion engine is powered, the microprocessor converts the rpm signal into a frequency modulated electric signal which generates a sound simulating that of a high performance vehicle. The sound trim adjuster prevents the frequency modulated electrical signal from being transmitted to the speaker means when there is a predetermined low motor rpm. The stitch is mounted on the dashboard of a vehicle for turning the microprocessor and amplifier on and off.
