Multi-Track Stereo Earphone Structure

Abstract

The invention provides a multi-track stereo earphone structure. The earphone body comprises the following components: a built-in horn and a resonant cavity which is connected to the horn; at least one bass hole, which is arranged in the middle position of the lower circumference of the resonant cavity; at least one treble hole, which is arranged in the middle position of the upper circumference of the resonant cavity; multiple midrange holes, which surround a sound hole plate in front of the horn, wherein the middle of the sound hole plate is a solid sheet which is facing a vibrating diaphragm center of the horn, aperatures of the multiple midrange holes are reduced from bottom to up layer by layer gradually, and the midrange holes surround the periphery of the solid sheet; so that the earphone body is desinged with a specially effective opening design, and output effects of the multi-rack stereoscopic surround sound as an advanced sound combination are realized.

Description

technical field [0001] The invention relates to a multi-track stereo earphone structure, in particular to the earphone with a special hole design on the earphone body, which can achieve the output effect of multi-track stereo surround sound. Background technique [0002] With the continuous advancement of science and technology, related audio-visual electronic products are developing towards the trend of light weight and miniaturization, providing people with entertainment and entertainment anytime, anywhere. In order to facilitate listening to audio-visual information without disturbing others, earphones have become a necessary accessory for electronic products. And many different types have been developed: such as earmuffs, earhooks, headbands and in-ears. [0003] Listening with headphones can provide better sound transmission effect, effectively overcome the unclear situation caused by sound transmission in the air, especially in noisy environments or intense sports such...

[0004] However, the various existing headphone structures are still not perfect in the design of sound field changes, such as Figure 8 As shown, there are only simple and random openings 52 on the sound hole sheet 51 of the existing earphone 50, which generally can only achieve the output effect of common high-bass stereo, but cannot provide the output effect of imitating the multi-channel loudspeaker stereo of advanced audio. For music appreciators who value sound quality, the existing headphone design simply cannot meet the requirements of music lovers who pursue immersive effects

[0005] In fact, as early as more than ten years ago, after the successful reform of subwoofer sound effect, high-end products imitating 7.1 speaker audio have been launched in the earphone market, but the overall planning of the existing structure is not yet proper, and the subwoofer in the machine completely affects The performance of the midrange and treble, the sound effect is greatly disturbed and still cannot be fully displayed, which is the defect that makes the original sound impossible to reproduce
