Earphone noise reduction method and device, main earphone, slave earphone and earphone noise reduction system

Abstract

The invention relates to the technical field of earphones and in particular relates to an earphone noise reduction method and device, a main earphone, a slave earphone and an earphone noise reductionsystem. The earphone noise reduction method is applied to a main earphone. The main earphone is wirelessly connected to the slave earphone and comprises a first transducer. The slave earphone comprises a second transducer. The main earphone and / or the slave earphone are / is wirelessly connected with an audio source apparatus. The earphone noise reduction method comprises the steps of acquiring a first environmental noise signal collected by the first transducer; receiving, based on wireless communication, a second environmental noise signal collected by the second transducer; generating, according to the first environmental noise signal and the second environmental noise signal, a first noise eliminating signal. Noise reduction of wireless earphones can be achieved. The noise reduction effect is good and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone noise reduction method and device, a master earphone, a slave earphone and an earphone noise reduction system. Background technique [0002] With the development of smart wearable device technology, Bluetooth headsets are increasingly sought after by the market. A traditional Bluetooth headset includes a left earphone, a right earphone and a cable, and the left earphone is connected to the right earphone through a cable. The left earphone or the right earphone can communicate with the mobile phone Bluetooth to realize remote playback or transmission of audio files. [0003] In the process of realizing the present invention, the inventor found at least the following problems in the traditional technology: First, because the left earphone and the right earphone are connected by a cable, the cable limits the freedom of the Bluetooth earphone, thus causing the user to ...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found at least the following problems in the traditional technology: First, because the left earphone and the right earphone are connected by a cable, the cable limits the freedom of the Bluetooth earphone, thus causing the user to be unable to flexibly use the Bluetooth earphone. earphone

Moreover, although the left / right earphones of traditional Bluetooth headsets are equipped with noise reduction functions, their noise reduction functions are implemented based on the hardware architecture of traditional Bluetooth headsets after all.

Furthermore, the noise reduction of traditional Bluetooth headsets is only a unilateral noise reduction method, that is, the left earphone collects the environmental noise on the left ear side for noise reduction, and the right earphone collects the environmental noise on the right ear side for noise reduction. The earphones cannot fully capture the ambient noise on the opposite side, so the effect of unilateral noise reduction is not ideal
