Description

Explanation transmitter and wireless explanation device Technical Field The application relates to the field of explanation devices, in particular to an explanation emitter and a wireless explanation device. Background The wireless explanation device is used as voice transmission equipment widely applied to scenes such as museums, scenic spots, conferences and training, and has the core function of transmitting voice signals of explanation persons to receiving equipment of listeners in a wireless mode, so that clear and stable voice explanation is realized. Conventional wireless teaching devices are mainly composed of a transmitter and a receiver, wherein the transmitter generally employs an Electret Condenser Microphone (ECM) or a silicon microphone (MEMS) as a sound pickup device. The microphone has the characteristics of high sensitivity, wide frequency response range, high fidelity and sound quality reduction and the like, and can realize high-quality voice acquisition and transmission in a conventional environment. However, in complex environments with noise intensity of more than 80 db, such as airports, factories, construction sites, and the like, the conventional microphone is easy to pick up a large amount of environmental noise due to the excessively high sensitivity, so that the signal-to-noise ratio of the voice signal is obviously reduced, and the voice definition and the intelligibility are seriously affected. In the prior art, part of schemes carry out noise reduction treatment on the acquired audio signals by introducing an AI algorithm, but the method has the following technical defects: 1. The AI noise reduction algorithm generally needs a certain processing time, which causes delay in voice signal transmission and affects real-time performance. 2. And the tone quality is damaged, namely the problems of high-frequency distortion, voice definition reduction and the like possibly occur in the noise reduction process, and the voice restoration effect is affected. 3. The strong noise environment adaptability is poor, and under the strong noise environment with the sound pickup distance being more than 80 dB, the AI noise reduction algorithm is difficult to effectively improve the signal to noise ratio, and the actual explanation requirement cannot be met. In addition, the traditional wireless explanation device has a plurality of defects in structural design, particularly in the aspects of volume, weight and portability, and the use experience of a user is obviously influenced. The technical defects seriously affect the use experience of users and restrict the further development of the wireless navigation system.
