电话机的内在结构是集成电路、电子元件构成的全电子模式,在一般常规操作使用下,话机出现的故障率是相当低的。但如果平时在使用中若不注意爱护保养,特别是在打电话时乱敲乱摔,而使话机遭受严重碰击,轻则话机机壳件损坏,重则引起机内电路及部件故障,如话机手柄内送、爱话器、话机叉簧开关、手柄与座机问话绳线、以及电路输入元件的损坏等。特别话机线路一旦遭受意外高电压和强电雷冲击,则会很容易直接击毁话机电路元器件。1.话机手柄中送、受话器在电话机听筒的手柄两端各设置有送 The internal structure of a telephone is an all-electronic mode made up of integrated circuits and electronic components. The failure rate of the telephone is quite low under normal operation. However, if you usually do not pay attention to the care and maintenance if you are not using the mobile phone, especially when making phone calls, you may suffer severe impact on the phone. For example, if the phone case is damaged, the circuit and component malfunctions may occur. For example, Phone handle to send, love phone, phone hook switch, handle and desk phone line asked questions, as well as the circuit input components such as damage. Special phone line in the event of accidental high voltage and strong lightning impact, it will be very easy to directly destroy the telephone circuit components. 1.
