The present invention provides an improved electroacoustic apparatus. The dynamic speaker of the said apparatus has two voice-coil windings. Its power amplifier circuit is a directly-coupled circuit with balanced two-way output. With the coordination of these components the double-terminal push-pull output may be realized with its pead-to-peak value of output voltage close to twice power voltage, and the sound quality is also improved. |
