Problems solved by technology

[0003] The call function of the existing feed-forward and hybrid ANC earphones mainly includes two implementation methods. One is to realize it through a call microphone. Beam Forming is implemented by feed-forward ANC microphones to eliminate noise on both sides of the human ear. However, since the beam formed by the two ANC microphones is an "8" shape, the noise on the back of the user's head It cannot be eliminated, and it is difficult to pick up only the call signal
[0004] It can be seen that only two ANC microphones in the existing ANC earphones are relatively fixed, and the received audio signal is also relatively stable, but the beams that can be achieved by the two microphones can only be in the shape of "8", which cannot cancel the user's head. The beam on the rear side; in addition, the call microphone cannot be effectively fixed, and the call microphone is usually a single one, which cannot perform uplink noise reduction processing

Abstract

The invention provides an earphone and a noise reducing method thereof. The earphone comprises two ear plugs and earphone lines connected with the ear plugs, wherein the ear plugs comprise shells and sounding units accommodated in the shells; noise reducing microphones are arranged in the two ear plugs respectively; a call microphone is fixed to one of the earphone lines; the call microphone and the two noise reducing microphones are used for performing uplink noise reduction on the earphone; and the two noise reduction microphones are used for performing downlink noise reduction on the earphone. Through adoption of the earphone and the noise reducing method thereof, a heart-shaped wave beam can be formed in front of the head of a user through the three microphones, so that the influence of external noise is lowered, and the call quality of the earphone is improved.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, relates to an ANC earphone with an uplink noise reduction function and a downlink noise reduction function and a noise reduction method thereof. Background technique [0002] At present, ANC (Active Noise Control, active noise control system) earphones mainly include feedforward, feedback and hybrid types. composition. [0003] The call function of the existing feed-forward and hybrid ANC earphones mainly includes two implementation methods. One is to realize it through a call microphone. Beam Forming is implemented by feed-forward ANC microphones to eliminate noise on both sides of the human ear. However, since the beam formed by the two ANC microphones is an "8" shape, the noise on the back of the user's head It cannot be eliminated, and it is difficult to pick up only the call signal. [0004] It can be seen that only two ANC microphones in the existing ANC ...
