Abstract

The invention provides an audio processing device of electronic equipment, comprising a high-frequency noise filtering device and a low-frequency noise filtering device, wherein the high-frequency noise filtering device comprises a first magnetic bead and a second magnetic bead; the low-frequency noise filtering device comprises a first capacitor and a second capacitor for filtering the low-frequency noise of an audio signal. The invention also provides an audio processing method of electronic equipment, comprising the following steps: receiving an audio input signal by the audio input deviceof the electronic equipment; consuming and adsorbing noise energy in the audio signal by the high-frequency noise filtering device so as to filter the high-frequency noise of the audio signal; and filtering the low-frequency noise of the audio signal by the low-frequency noise filtering device. According to the method and the device for inhibiting audio breakthrough interference, the capability of the electronic product on inhibiting audio breakthrough interference can be obviously improved. According to the method and the device, the function of inhibiting noise is realized by the magnetic beads and the capacitors, and the product design cost is saved.

Description

technical field [0001] The invention relates to the field of audio signal processing, in particular to an audio interference suppression device and method for electronic equipment. Background technique [0002] Due to the rapid development of modern electronic products, the space electromagnetic environment is very complex and harsh. Space electromagnetic radiation greatly affects the performance of electronic products, and poses higher challenges and requirements for the anti-interference performance of electronic products. GB17626, IEC61000-4 and EN301489 all have detailed regulations on the audio breakthrough performance of electronic products. [0003] The audio breakthrough test is to measure the ability of mobile phones and other electronic devices to correctly demodulate and receive and modulate and transmit audio signals when they are interfered by external signals. In the prior art, methods to improve product immunity and suppress interference include: [0004] 1...
