Description

Technical Field

[0001] The utility model relates to the technical field of wireless earphones, in particular to a wireless earphone with a noise reduction function. Background Art

[0002] Noise-canceling headphones are headphones that use some method to reduce noise. There are two types of noise-canceling headphones: active and passive. Active noise-canceling works by generating sound waves that are equal to or opposite to the external noise, neutralizing it. Passive noise-canceling headphones primarily create a closed space around the ear, or use sound-isolating materials like silicone earplugs to block out external noise.

[0003] Whether active or passive noise reduction headphones, they both reduce the amount of external noise intake, but they cannot achieve a good noise reduction effect on the noise caused by the vibration generated by the headphones themselves during work and other reasons. The utility model is based on the principle of passive noise reduction headphones and a multi-noise reduction cavity structure design to propose a new type of wireless headphones with noise reduction function, which can effectively target various noises.
