Abstract

The invention discloses a method, equipment and system for reducing headset noise, aiming at providing a method for reducing the headset noise without addition of hardware equipment and further saving the hardware equipment. The method comprises the following steps of: processing environment noise acquired by an MIC (Microphone) of a headset through a headset interface, an analog/digital conversion circuit, a digital filtering circuit, an audio decoder and a digital/analog conversion circuit of equipment to obtain reverse-phase environment noise corresponding to the environment noise; and overlaying the reverse-phase environment noise into an audio signal and transmitting the reverse-phase environment noise to the headset so that the reverse-phase environment noise and the environment noise heard by human ears can be cancelled out each other to realize noise reduction of the headset. By adopting the technical scheme disclosed by the invention, the headset noise can be reduced without improving the headset, or equipment connected with the headset, the procedure of reducing the headset noise is simplified, the hardware equipment is saved; and the hardware equipment does not need to be improved, thus the commonality and the flexibility of reducing the headset noise are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for reducing earphone noise. Background technique [0002] At present, there are more and more types of headphones, and the structure of the headphones can be as follows: figure 1 As shown, it includes a headphone jack, a microphone with a key switch and an earhook, wherein: the headphone jack is used to be inserted into the headphone jack of the main device (such as mobile phone, MP3, MP4, etc.) to realize the connection between the headphone and the main device At present, the standard 3.5mm headphone jack is used more often; the button switch of the microphone is used to control the connection or hang up of the call. [0003] The current earphones have not yet implemented the corresponding noise reduction function. Therefore, when the user is listening to music or talking on the phone, due to the influence of the surrounding environment, there is ...
