Embodiment Construction
[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0035] In the existing headphone equipment, it is necessary to distinguish the left and right sound channels according to the left and right marks, and this method is not convenient. Aiming at this technical problem, the embodiment of the present application provides a solution. The basic principle is: set two microphones on both sides of the referenc...

Embodiments of the present invention provide a left and right channel determining method and an earphone device. Two microphones are arranged on either side of a reference line of any earphone of an earphone device, sound signals collected by the two reference microphones at moments t and t + T are acquired on the basis of a delay T of the same reference sound source signal reaching the two microphones, a correlation of the sound signals collected by the two microphones at the different moments is calculated, a relative position of the earphone and an actual sound source is determined according to the corresponding correlation, and thereby a channel corresponding to the earphone is determined. In this way, a user does not need to manually distinguish left and right earphones during use, and channels corresponding to the earphones can be automatically determined, allowing the earphones to adopt corresponding processing methods to process left and right channel signals, thereby improving the quality of sound signals and improving user experience.
Description
technical field [0001] The present application relates to the technical field of terminals, in particular to a method for determining left and right sound channels and an earphone device. Background technique [0002] As an important accessory of terminal equipment such as mobile phones, computers, and walkmans, earphones bring great convenience to people's life and work. The earphone generally includes two left and right earphones, which are respectively worn on the left ear and the right ear of the user. This can form the left and right channels, thereby improving the stereo effect of the sound. [0003] In the prior art, it is mainly to add left and right marks on the earphone to distinguish the left and right sound channels. When using it, the user needs to wear the left earphone on the user's left ear to output the left channel signal, and wear the right earphone on the user's right ear to output the right channel signal. If the user wears the left and right earphone...
