[0002] Fixed telephone is also referred to as fixed telephone. It usually refers to a telephone that is fixed in a certain location and does not move. Contrary to mobile telephones, it is mostly used in business units. Fixed telephones are one of the important means of communication in modern times. Vibration of sound utilizes the vibration of the telephone The microphone modulates the current and voltage on the telephone line, that is, the sound is converted into a voltage signal and transmitted to the other end of the telephone through the telephone line, and then the microphone is used to convert the voltage signal into a sound signal. Because it is usually fixed in one position, the academic name is Fixed telephones, which are commonly referred to as landline telephones, but when the fixed telephone is in use, dust often falls on the outer surface, which makes the cleaning work more cumbersome and inconvenient to use
