Problems solved by technology

This usually has the advantage of ensuring a fixed position between the microphone and the user's mouth, but the placement of the microphone is limited due to lack of space
Moreover, the distance between the microphone and the earbud speaker is relatively close, and this close distance can cause acoustic echo problems that are not easy to solve

Abstract

The invention discloses a headset and a method for uplink noise cancellation for headsets. The headset comprises: at least one earpiece including at least one speaker; a connector for connecting withan electronic device; and a control box connected to the earpiece and disposed on an earphone cable between the earpiece and the connector, wherein at least three microphones for uplink noise cancellation is placed in ta control box.

Description

technical field [0001] The present invention relates to the technical field of earphones, and more particularly to an earphone and an uplink noise cancellation method for the earphone. Background technique [0002] More and more headphones now include noise cancellation, which includes uplink noise cancellation and downlink noise cancellation. Uplink noise cancellation is to reduce noise and enhance the desired audio components in the signal to be played to the user, so that the user can clearly hear the sound played. In downlink noise cancellation, a microphone is used to capture ambient sound (noise) and generate a waveform that cancels out the ambient sound. This waveform is mixed with the signal to remove noise. For example, headphones from the companies Bose and Sony employ this type of noise cancellation. [0003] Traditional headsets on the market usually employ a dual microphone solution for uplink noise cancellation. In most cases, the microphone is located on t...
