Data transmission device used in wireless microphone system

Abstract

The present invention is a data transmission device used in a wireless microphone system, in particular, the host and the transmitter are respectively equipped with wireless communication components, so that the system architect can implement two-way and multi-party wireless data transmission; its main structure is composed of the host and the transmitter. The transmitters are respectively equipped with wireless communication components, which can be used as a function of a two-way and multi-directional digital frequency-to-frequency data synchronization update system in a wireless connection between the units. The system can directly set the various operation functions of the host and the microphone, and the system can give the host to remotely assign and set the frequency transmission of most microphones. In case of abnormality or interference, you can immediately directly Performing various real-time frequency updates and troubleshooting, effectively solving many limitations and inconveniences in the process of wireless data transmission with existing microphones, it is a function that simplifies system connection, just like a local area network.

Description

technical field [0001] The present invention relates to a wireless data transmission device, in particular to a wireless communication component installed on the receiver and the transmitter respectively, which can be matched with a personal computer and controlled by software to act as a two-way System architecture with multi-directional digital frequency data transmission control. Background technique [0002] By the way, the leisure activities of modern people are quite diverse. From the invention of karaoke in the early days to the popularity of KTV and DVD players, microphones have been widely used in daily life. Usually, a wired microphone is selected as the audio-visual equipment used in the box. This type of microphone is mainly connected to the control host through a cable, and all functions such as volume, high and low, and loudness are unified on the host. Choose the setting, and the microphone usually has to be fixed in the corner or on the wall with the microph...

Problems solved by technology

[0004] Although the wireless microphone has many advantages in use, it is often seen that when the teacher uses the microphone in the classroom, because the receiving distance of the microphone is too short, the receiving range of the main unit will be exceeded if the teacher is not careful, and the volume will fluctuate suddenly and suddenly. This will inevitably affect the class process, and because the operation setting is limited to unilaterally on the host, once the class is held in a large classroom, it is possible that when the microphone is interfered by external noise and the radio effect is poor and the abnormal sound is generated, it is located in the classroom. A lecturer somewhere has to quickly go back to the control panel and reset the microphone to remove all malfunctions. This is indeed troublesome for teachers who use microphones to teach every day. In addition, in today's teaching, conferences and educational training , There are a lot of multimedia video broadcasts that need to be played through the computer, but the system data between them often cannot be connected to each other, causing the user to repeatedly set and test the personal computer, the control host and the microphone to achieve the best results. For this reason, it is necessary to try to solve it together
