Electronic horn and method for mimicking a multi-frequency tone

摘要

An electronic horn for mimicking a multi-frequency tone includes a wave signal generator for generating an input signal and a complex signal generator for generating a complex signal across a transducer to mimic the sound and sound intensity of an electromechanical horn. The complex signal generator produces a complex output signal which may derive from a plurality of product signals, each product signal being derived by processing the input signal. A first product signal drives the transducer through a full bridge motor driver circuit and a second product signal is converted to a control signal by the signal processor circuit. The control signal is used to control the full bridge motor driver circuit to drive the transducer.
