This AC electronic music door bell is composed of general electronic door bell, rectified power supply, relay and power amplifier and does not need battery to power it.───本发明涉及一种用交流电的电子音乐门铃，由普通电子门铃加整流电源、继电器及功率放大器构成。本发明不再需要电池供电。
It is only when the correct voltages are applied to the A/C amplifier from the key inputs that the primary output (the A/C compressor relay) will be energised.───只有A/C扩大器上的电压是来自输入端的正确电压时，初级输出（即A/C压缩机继电器）才会被激活开启。
