[摘要]学习收音机和来电显示电话机的工作原理,了解整机安装的一般步骤,并掌握焊接元件的操作程序.收音机就是把从天线接收到的高频信号经检波还原成音频信号,送到耳机变成音波。电话通信是实现声能与电能相互转换的用户设备。由送话器、受话器和发送、接收信号的部件组成。发话时，由送话器把话音转换成电信号，沿线路发送到对方；受话时，由受话器把接收到的电信号还原成话音。本次实习完成了收音机和来电显示功能的电话机的装配，并能正常工作。本次试验通过单人单组装配一台收音机和来电显示功能的电话机，焊接调试，排除遇到的故障。

[Abstract]Learning radio and telephone caller ID works, to understand the general steps to install the machine and a welding torch component of operating procedures. Radio is the high frequency from the antenna to restore the audio signal by the detector signal to the headphones into Sound waves. Telephone communication is to achieve sound energy and energy conversion of the user equipment. By the transmitter, receiver and transmit, receive signal components. Speaker, by the transmitter converts the voice signal, is sent to each other along the way; by words, by the receiver to restore the received voice signal. The internship completed radio and telephone caller ID function of the assembly, and can work properly. Through this experiment, one group assembled for a single radio and telephone caller ID function, weld testing, preclude the failure encountered.

[Key words]radio; telephone; welding
