Troubleshooting of repeater

1. The most common problem is that the voice is shaky and the speed is unstable. The main reason is that the aging of the belt, the torque of the motor can not be completely transmitted to the main shaft, resulting in throwing, or or transmitted torque unequal, resulting in shaking of the voice. This kind of fault is better repaired, just change the belt of the same type. But the best use of the original belt, not the original belt, often not long before the aging and relaxation, mainly due to the current market quality of the belt poor.
2, after using the walkman for a long time, the surface of the belt pulley will be polished, resulting in not enough friction to drive the tape. The method is to remove the belt pulley, to burnish the aging layer of the surface with very fine water sand paper, and to obtain greater frictional force by adjusting the pressure of the belt pulley spring

Repetition machine principle

On the basis of portable radio cassette recorder, the repeater has added a multi-function language signal access device which is formed by micro processing chip and digital memory chip. It is in the tape playback and converts the analog signal to digital signal, stored in digital memory chip; repeat state transforms the digital signal into analog signals in the memory, the power amplified by the speaker to restore voice. The conversion of all the states of the repeating machine is accomplished under the control of the micro processor chip of the computer.

Brief introduction of repeater

A repeater is a machine that stores sounds and plays them repeatedly. On the basis of portable radio cassette recorder, a multi-function language signal access device is formed after micro processing chip and digital memory chip. It is in the tape playback and converts the analog signal to digital signal, stored in digital memory chip; repeat state transforms the digital signal into analog signals in the memory, the power amplified by the speaker to restore voice.
