Problems solved by technology

At present, the industry generally designs better built-in devices of mobile terminals, and spends a lot of money to develop and install noise reduction devices to improve sound quality and listening experience, but it ignores the impact of external environmental noise on the audio when it directly enters the human ear. The impact of the signal, so that no matter how good the design of the mobile terminal is, the sound that finally enters the human ear is very bad, which greatly reduces the user experience

Abstract

The invention provides an external noise reduction device for a mobile terminal and a noise reduction method of the external noise reduction device. The external noise reduction device is used for externally connecting between the mobile terminal and a headset and comprises a microphone, a preprocessing module and a main processing module, the microphone is used for acquiring external environmental noise, the preprocessing module is used for preprocessing the external environmental noise, the main processing module is used for loading the preprocessed external environmental noise to digital audio signals outputted by the mobile terminal and transmitting the preprocessed external environmental noise to the headset, and the external environmental noise directly entering ears is eliminated by the aid of the loaded external environmental noise. Effective noise reduction can be performed for audio signals directly entering the ears, and the external noise reduction device is low in cost and high in transportability.

Description

technical field [0001] The present invention relates to the technical field of terminal and audio data processing, in particular to an external noise reduction device for a mobile terminal and a noise reduction method thereof. Background technique [0002] As the audio functions of mobile terminals such as smart phones become more and more perfect, the frequency of using smart phones to plug in earphones to play music or make calls is getting higher and higher. At present, the industry generally designs better built-in devices of mobile terminals, and spends a lot of money to develop and install noise reduction devices to improve sound quality and listening experience, but it ignores the impact of external environmental noise on the audio when it directly enters the human ear. No matter how good the design of the mobile terminal is, the sound that finally enters the human ear is very bad, which greatly reduces the user experience. Contents of the invention [0003] In vie...
