Headphone

Abstract

The invention provides a headphone, comprising two earmuffs and a head hoop through which the two earmuffs are connected. Each earmuff comprises a shell, an ear pad, sound absorption cotton and a pickup. Each ear pad is set on the outside surface of each shell. The sound absorption cotton is set in a cavity of each shell. Empty areas of each cavity are filled by the sound absorption cotton. The outside wall of the pickup is coated by a layer of rubber pad. Each pickup is fixedly set on the shell through the rubber pad. According to the headphone provided by the invention, the sound absorptioncotton is set in the cavity of each shell and shapes and sizes of the empty spaces of the cavity of each shell are extracted as shape parameters of the sound absorption cotton, so all empty areas of the cavity of each shell can be filled up by the sound absorption cotton, noises can be absorbed by the sound absorption cotton omni-directionally and a passive denoising effect is good; vibration transmission among parts is reduced through rubber pads; and the ear pads contact auricles of a wearer closely, so the passive denoising effect is further improved.

Description

technical field [0001] The invention relates to the technical field of loudspeaker components, in particular to a headset. Background technique [0002] With the rapid development of high-tech electronic products and the continuous popularization of mobile communication products, earphones, as an indispensable accessory for these products, have also been widely used thereupon. With the continuous improvement of people's needs in life, consumers have higher and higher requirements for earphones. In addition to having stable communication quality, they must also be able to isolate unnecessary noise and perform normal communication in noisy or even high-noise environments.

AI Technical Summary

Problems solved by technology

[0003] Headphones currently on the market can be classified into head-mounted and earplugs according to the way they are worn. The noise reduction methods of headphones mainly include: using sound-insulating materials for physical noise reduction (also known as passive noise reduction) and electronic noise reduction. There are two types of active noise reduction (also known as active noise reduction) for lines. However, for some types of noise sources such as pulses and shock waves, active noise reduction cannot achieve noise reduction effects, and only physical noise reduction can be used. Therefore, physical noise reduction noise is extremely important

[0004] Among the existing technologies, the currently used headphones are usually only provided with simple rubber pads in the gap between the shells for physical noise reduction. The passive noise reduction effect is poor, and it can only isolate the noise within 25dB at most, which cannot meet the needs of users. Require
