ある。[Detailed Description of the Invention] This invention compares the input signal and the speaker terminal signal (including the back electromotive force) in order to operate the speaker more faithfully in response to the input signal. In this system, the ``abare signal'' of the speaker's operation appears) is returned to the main amplifier for driving the speaker, and the speaker is operated faithfully to the waveform of the input signal.
以下ダイヤブロックグラムの動作説明をする。The operation of the diamond block diagram will be explained below.
