Audio signal driver for flat sound generator

摘要

An audio driver for a flat sound generator is coupled to the sound generator. The audio driver includes a power amplifier and an audio-amplifying transformer, the power amplifier receiving an input audio signal and the audio-amplifying transformer transforms the input audio signal into an output audio signal to drive a flat sound generator. The flat sound generator includes a perforated electrode plate and a diaphragm. Wherein, the audio-amplifying transformer and the flat sound generator form a low-pass filter effectively.
