Embodiment Construction
[0020] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0021] In the current wireless communication system, there are a variety of wireless protocols that can be used collaboratively in the system. Currently, civilian frequencies are used and are easy to develop and use. One is the WIFI wireless network that we are familiar with, and the other is the ZIGBEE wireless network for the Internet of Things. . Considering the flow of audio data and the availability of wireless network equipment, WIFI wireless network is selected as the medium of audio transmission in the present invention. The WIFI wireless network has a mature wireless frequency band management protocol, and multiple WIFI wireless network devices can work together normally and reliably without user intervention; at the same time, the ...

The invention discloses a wireless microphone system based on a WIFI (wireless fidelity) wireless network connected to a network audio frequency receiver, wherein the wireless microphone system comprises a power supply module, a management and control module, a WIFI wireless network interface, a pick-up device system and a speaker system; the power supply module is used for supplying electricity to the wireless microphone system; the management and control module is used for managing and controlling the wireless microphone system; the pick-up device system is used for collecting audio data; the speaker system is used for playing the audio data, and the control and management module is respectively connected to the power supply system, the WIFI wireless network interface, the pick-up device system and the speaker system. An analogue or digital wireless transmission mode of the traditional wireless microphone is replaced by the WIFI wireless network, so the wireless management is more convenient and effective, and the tone quality of the microphone is clearer and more sable. In addition, two WIFI wireless network cards at different work frequency bands are utilized, so as to avoid interference of an electromagnetic signal to the wireless network cards.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a wireless microphone system based on a WIFI wireless network. Background technique [0002] Known wireless microphones generally have two types of wirelessly transmitting analog audio signals and wirelessly transmitting digital audio signals. With the popularization of digital technology, there are fewer and fewer wireless microphones that transmit analog audio signals wirelessly. Most wireless microphones use digital audio technology to improve audio quality and wireless stability. However, the wireless digital transmission technology used by wireless microphones has two relatively big problems. One is the problem of wireless frequency band matching and conflict; the other is the problem of limited transmission distance. The problem of wireless frequency band matching and conflict is because the current wireless microphones use independent wireless communication modules, a...
