Wireless receiver inside comprises MCU processor, receiver module, Power supply part, audio frequency demodulation module, D/A modular converter, and outside has connector, LCDs, volume knob, button.
2) controller can carry out controller self speech by one-touch switching and receive the switching of wireless explanation speech machine speech.
3) the Power supply part of wireless explanation speech machine, controller and wireless receiver is that chargeable lithium cell is powered, and can be recycled, and system component devices is small and exquisite, can carries with.
4) connector of wireless explanation receiver and controller comprises Mike's jack, charge port.
5) connector of wireless receiver comprises earphone jack and charge port.
Compared with prior art, its advantage is the design of this utility model:
1) this system is without the need to installation wiring, adopts digital radio transmission technology, sound clarity, anti-interference.A people many people that makes a speech can listen to, also can many people many people that makes a speech listen to.
2) human hair make peace many people speech control mode take one-touch switching, convenient and swift.
3) controller has stereo process function, the information receiving different frequency range number can be transferred to same frequency range after treatment and launch, and ensure that the clear of tonequality.
4) quantity of wireless receiver is unrestricted, can unrestrictedly receive, and is applicable to the large and small meeting of any scope.
5) the Power supply part of this system adopts light, the capacious chargeable lithium cell of quality to power, and enables long-time use, and environmental protection.
This utility model is after the demand of profound understanding user, according to the actual service condition of conference hall, the a set of six directions one wireless explanation conference system installed without the need to wiring of design, a people can be supported to explain speech for this system or many people explain speech, and this function can be reached by one-touch switching, when many people make a speech, controller passes through stereo process, the signal of different frequency range will be received, by being converted into transmitting of same frequency range after stereo process, the receiver of unrestricted quantity receives the content of explanation simultaneously, this system not only solves fixed conference system and installs inconvenient problem, also solve many people to make a speech interference-free problem, be very suitable for the convention Room used, the places such as Conference Hall, that one is convenient for carrying, the conference system of handled easily.
