Audio adapter for conversation in prison

Abstract

The invention discloses an audio adapter for conversation in a prison. The audio adapter comprises an audio input module, an audio amplifying module, an impedance matching module, and an audio output module, wherein the audio input module is used for inputting an audio signal; the audio amplifying module is used for amplifying the input audio signal, and transmitting the amplified audio signal to the impedance matching module; the impedance matching module is used for performing smooth processing on the amplified audio signal, and transmitting the smoothly processed audio signal to the audio output module; and the audio output module is used for outputting the smoothly processed audio signal. The audio adapter for the conversion in the prison disclosed by the invention can effectively adapt to a video-audio compression card in a prison helping-educating system, the noise interference is reduced, and the sound articulation is improved.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio adapter for prison conversation. Background technique [0002] In the process of one-on-one remote teaching through the prison teaching system, there is a problem of communication delay. Aiming at this problem, the traditional solution is to increase terminal configuration and server configuration. However, this traditional solution cannot effectively compress audio and video, and cannot fully guarantee lip synchronization. Therefore, in a new solution we introduced a surveillance-grade hardware video and audio compression card. [0003] However, during the actual debugging process of the assistant education system after the introduction of the video and audio compression card, the prison guards generally reported that the sound of the microphone that comes with the headset is too small, and the use of pickups cannot effectively pick up sound in a small range....

Problems solved by technology

[0003] However, during the actual debugging process of the assistant education system after the introduction of the video and audio compression card, the prison guards generally reported that the sound of the microphone that comes with the headset is too small, and the use of pickups cannot effectively pick up sound in a small range

At the same time, the camera in the teaching assistant system is powered by a traditional 12V transformer alone, and there is a problem of poor current stability.
