Embodiment 1

[0021] see figure 1 , the present invention provides a kind of anti-jamming audio and video playing system here by improving, comprise audio equipment 1, analyze audio frequency module 2, eliminate module 3, antijamming module 4, signal amplifying module 5 and power supply module 6, audio equipment 1 output The signal is analyzed by the analysis audio module 2. After the audio analysis is completed, the common mode signal will be imported into the elimination module 3 through the analysis audio module 2, and the analyzed differential mode signal can be output to the anti-interference module 4, and the analysis audio module 2 The output noise signal is processed by the elimination module 3, and the differential mode signal of the analysis audio module 2 is imported into the anti-interference module 4. After the anti-interference module 4 completes the elimination of the differential mode noise, the signal is amplified by the signal amplification module 5 to better import In the...

Embodiment 2

[0026] The present invention provides an anti-interference audio and video playback system through improvement, which solves the problem that different external signals affect the use of signal equipment, thereby causing bad user experience to users and causing troubles to users.

[0027] The present invention provides an anti-interference audio and video playback system through improvement, and its working principle is as follows;

[0028] First, the audio device 1 first inputs the audio transmission signal into the analysis audio module 2 and waits for the next step to be processed;

[0029] Second, analyze the common-mode detection signal unit 21 and the differential-mode detection signal unit 22 in the audio module 2 thereafter to classify the audio signals introduced into it, and the common-mode detection signal unit 21 will detect the common-mode signal. It can be input into the elimination module 3, and the detected differential mode signal will be input into the anti-j...

Abstract

The invention discloses an anti-interference audio and video playing system.The anti-interference audio and video playing system comprises audio equipment, an audio analysis module, an elimination module, an anti-interference module, a signal amplification module and a power module.According to the anti-interference audio and video playing system, noise of common-mode signals is preliminarily screened out through the audio analysis module; and then noise in the differential-mode signal is secondarily screened through the anti-interference module and the power supply module, and finally the filtered signal is amplified through the signal amplification module and is guided back to the audio equipment, so that the user experience of a user can be improved, the processing effect on external signal noise is effectively improved, and the user experience is improved. Meanwhile, the situation that other external devices interfere with signals output by the audio device is avoided, and the elimination module and the differential mode noise elimination unit are arranged, so that the filtered noise can be eliminated.

Description

technical field [0001] The invention relates to the field of anti-jamming, in particular to an anti-jamming audio and video playback system. Background technique [0002] In modern life, the intelligence of electronic products has become a major trend in the development of the industry. There are more and more terminal products such as smart phones, smart homes, tablet computers, Internet of Vehicles, and smart wearables, and they are used more and more frequently. Users usually use smart terminals The bluetooth function in the computer transmits data with each other, or controls the play, pause and change of the song of the bluetooth device through the standard protocol provided by bluetooth, or connects through the cable, and due to the mutual connection between the power grid, wireless network and various intelligent electronic products Crosstalk produces audio interference, and these audio interferences are likely to affect the audio playback signal used, causing a bad e...
