Abstract
A hand-held automotive sound replicator having a case provided with a keyboard, a speaker and a power switch. The case houses a microprocessor responsive to a key input signal from the keyboard for providing data indicative of the key input signal for accessing a programmable read only memory via a random access memory. The programmable read only memory provides program and sound files to be stored in a microprocessor via the random access memory and through a controller. The microprocessor outputs digital sound signals to a digital-to-analog convertor, which provides an analog signal to a sound generator. The output from the sound generator is regulated by a volume control through an amplifier to the speaker.
