Embodiment Construction

[0022] The frequency pairing method of the wireless microphone system of the present invention is to add a simple simplex or duplex communication module on the receiver and the wireless microphone transmitter respectively in the original simplex communication wireless microphone system for frequency pairing. control. Based on this, the frequency pairing function is realized. The frequency binding function can use the original communication link of the receiver and the wireless microphone to cooperate with the frequency binding module circuit to complete the frequency binding work, or use the frequency binding module circuit to complete the frequency binding independently, which depends on the basic structure of the frequency binding module.

[0023] The composition of the frequency pairing module in the present invention can select different communication modes to realize the frequency pairing according to different use environments and related functions of the frequency pairi...

Abstract

The invention discloses a wireless microphone system frequency matching method. The wireless microphone system comprises a wireless microphone and a receiver. The wireless microphone comprises a first microcontroller, a first carrier generation module, a transmitting chain and a frequency matching receiving module. The receiver comprises a second microcontroller, a second carrier generation module, a receiving link and a frequency matching transmitting module. When the wireless microphone and the receiver carry out frequency matching, the first microcontroller closes the transmitting chain. The frequency matching receiving module is switched on. The second microcontroller closes the receiving link. The frequency matching transmitting module is switched on. The second microcontroller controls the frequency matching transmitting module to transmit frequency matching data to the frequency matching receiving module. The first microcontroller modifies the carrier frequency of the first carrier generation module according to the frequency matching data received by the frequency matching receiving module. According to the frequency matching method provided by the invention, the operation is simple; dependence on a use environment is small; system failures caused by improper manual operation are reduced; the installation of the wireless microphone system is greatly simplified; and the installation cost is reduced.

Description

[technical field] [0001] The present invention relates to wireless microphone frequency linking, in particular to a wireless microphone system frequency linking method. [Background technique] [0002] Wireless microphone frequency pairing refers to transferring the available frequency point information retrieved by the receiver to the handheld microphone, so that the handheld microphone and receiver can work normally in the same frequency mode. [0003] When installing a common wireless microphone system for entertainment, it is necessary to manually adjust the transmission frequency of the receiver and the microphone before it can work normally. This installation method is very cumbersome, and it also brings a lot of inconvenience to the later maintenance of the system. In order to solve this problem, the manufacturers basically adopt the infrared frequency matching method. Although this method of frequency binding solves the cumbersome process of manual frequency adjustme...
