Embodiment Construction

[0045] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0046] Scenario overview

[0047] As mentioned earlier, in the scene where the user uses the TWS Bluetooth headset while exercising, there is usually a lot of signal noise in the surrounding environment, which will interfere with the audio transmission quality, and in addition to general environmental noise, There will also be motion noise due to the bluetooth sending end, that is, the receiving end of the mobile phone and the bluetooth headset, and the asynchronous movement between the bluetooth headset. Therefore, in order to make the TWS bluetooth headset ...

Abstract

The invention discloses a noise reduction method and system for a high-performance TWS Bluetooth audio chip, and electronic equipment. The motion augmentation feature map of a motion difference feature map is used to to improve the expression capability of the motion difference feature map for relative motion information between a mobile phone and a Bluetooth earphone, meanwhile, the feature distribution of the motion difference feature map in the time dimension in the corresponding high-dimensional feature space is relatively sparse, so that a motion feature space which is more suitable for reflecting the relative motion feature between the mobile phone and the Bluetooth earphone is constructed, and therefore, the feature distribution density is improved, and the regression operation performed by a decoder model can obtain a better effect.

Description

technical field [0001] The present invention relates to the field of audio intelligent noise reduction, and more specifically, to a noise reduction method, system and electronic equipment for a high-performance TWS Bluetooth audio chip. Background technique [0002] The full name of TWS is True Wireless Stereo, which means true wireless stereo. TWS technology is developed based on Bluetooth chip technology. Its working principle is that the mobile phone is connected to the main earphone, and then the main earphone is quickly connected to the auxiliary earphone wirelessly to realize the true wireless separation of the left and right channels of Bluetooth. That is, the audio data is first transmitted from the mobile phone to the main earphone, and then from the main earphone to the auxiliary earphone. [0003] At present, for example, in the scene where the user uses the TWS Bluetooth headset while exercising, there is usually a lot of signal noise in the surrounding environm...
