Sound box microphone two-way synchronous wireless audio transmission live broadcast system and method

Abstract

The invention is suitable for the technical field of live broadcast, and provides a sound box microphone two-way synchronous wireless audio transmission live broadcast system and method, and the system comprises a sound box microphone which comprises a sound pickup, a preamplifier, a DSP audio processor controller, a power amplifier, a loudspeaker and a Bluetooth module, and also comprises a wireless audio receiving and transmitting module, the sound pickup is used for acquiring human voice signals; the pre-amplifier is used for amplifying human voice signals collected by the sound pickup; and the Bluetooth module is used for receiving an accompany signal of an intelligent equipment terminal. The beneficial effects of the sound box microphone two-way synchronous wireless audio transmission live broadcast system lie in that the live broadcast can facilitate the monitoring, and the two-way synchronous wireless audio transmission avoids the audio time delay; the problems of stumbling and constraint caused by the audio cable are perfectly solved, and faults caused by physical audio cable connection are greatly reduced.

Description

technical field [0001] The invention belongs to the field of live broadcast technology, and in particular relates to a speaker microphone two-way synchronous wireless audio transmission live broadcast system. Background technique [0002] With the development of society, people's lives have entered the information age, and the spiritual life of entertainment is closely integrated with information; live broadcast products are common equipment for Internet celebrities, home entertainment, and commercial sales live broadcast, but many live broadcast products on the market still exist as follows insufficient: [0003] 1. In the traditional live broadcast, the microphone is equipped with a cable for earphone monitoring, and the audio cable is connected to the smart device for live broadcast.

AI Technical Summary

Problems solved by technology

[0003] 1. In the traditional live broadcast, the microphone is equipped with a cable for earphone monitoring, and the audio cable is connected to the smart device for live broadcast. However, this live broadcast method wears earphones for a long time. Wearing earphones for a long time is easy to damage the hearing of the ears. The earphones do not have the ear return function, and the monitoring effect is not good. good;

[0004] 2. Although the ordered traditional sound card equipment can be connected to the speaker through the sound card, but the live broadcast connects the human voice signal to the smart terminal through a special audio cable for live broadcast. convenient;

[0005] 3. The wireless audio transmission of the existing connected smart devices is mainly the Bluetooth module. The technical protocol of the Bluetooth module itself has the disadvantage of not being able to connect the human voice to the smart device for live broadcast in real time. The fatal disadvantage is that the sound delay is not good. There is no solution to the synchronization problem. It also needs to be carried out with headphones, and it is also easy to wear headphones for a long time and easily damage the ears.
