摘　　要：提出了一种基于单片机技术的音乐门铃设计方案.门铃以STC15L104单片机为核心,辅以低压差电池反接保护、喇叭驱动、门铃按键三个外围线路.门铃的乐曲通过单片机编程录入,乐曲录入程序采用了单字节压缩编码技术,并具有音调、半音、休止符等处理功能.门铃适合3 V电池供电,并通过单片机低功耗掉电技术,降低了门铃的待机电流,延长了电池的使用时间,实测待机电流低于1 u A.A design and implementation scheme of music doorbell based on single-chip microcomputer technology is presen- ted in this paper, which is simple and reliable, by using STC15L104 single-chip and three peripheral circuits, such as the circuit of opposite connection protection for low drop-out, the circuit of loudspeaker drive and the circuit of doorbell button. The music is entered into the doorbell through the program of single-chip, which processes pitch, half-tone and rest based on the single byte compression and encoding technology. The doorbell adapts to battery of 3V and can reduce standby cur- rent by using the ＂power down＂ technology of single-chip which can also bring longer life cycle of the battery. The meas- ured value of standby current is lower than 1 uA.
