Abstract

The invention provides a wireless teaching device. The wireless teaching device comprises a transmitting end and a receiving end, wherein the transmitting end comprises a UHF (Ultra High Frequency) voice processing-transmitting chip, an embedded digital microphone circuit, an external microphone interface, a microphone selection circuit, a first antenna matching circuit, a 2.4G radio frequency transmitting chip, a key unit, a laser driving circuit, a six-axis gravity angular velocity sensor and a second antenna matching circuit, wherein the receiving end comprises a UHF voice receiving-processing chip and a 2.4G radio frequency receiving chip; the UHF voice processing-transmitting chip is connected with the first antenna matching circuit; and the 2.4G radio frequency transmitting chip is connected with the UHF voice processing-transmitting chip, the key unit, the laser driving circuit, the six-axis gravity angular velocity sensor and the second antenna matching circuit. The wireless teaching device has the beneficial effects that a pairing way is convenient; automatic pairing can be performed at startup; and the functions of automatically allocating UHF frequency points and encrypting can be realized according to pairing ID.

Description

technical field [0001] The invention relates to the field of multimedia teaching, in particular to a wireless teaching device. Background technique [0002] With the development of the education industry, teaching methods are becoming more and more modernized, and multimedia teaching equipment, such as wireless microphones, laser pointers, etc., has begun to be used. In the teaching process, the wireless microphone needs to be paired before use. Under normal circumstances, the wireless microphone is the same as the receiver. If the encryption method is not used, the voice picked up by one wireless microphone or the voice picked up by multiple wireless microphones, the receiver will If it can be received, there will be a phenomenon of channel crossing. Regarding the wireless microphone pairing method, the easiest way in the past is to burn the ID into the EPROM during production. When initializing, the chip reads the ID from the EPROM to initialize the transceiver chip. The ...
