In-ear earphone

Abstract

The invention provides an in-ear earphone, and belongs to the technical field of earphones. The problems of poor low-frequency reproducibility, poor sealing performance and more serious sound leakage of a conventional in-ear earphone are solved. The in-ear earphone comprises earphone bodies, wherein each earphone body comprises a main shell with an accommodation cavity and a loudspeaker arranged in the main shell; a front cover is arranged at the front end of each main shell; a sound guide tube axially extends from the middle part of each front cover; the front end of each loudspeaker is in sealing connection with the inner wall of the corresponding front cover; the inner wall of each front cover is gradually reduced from the rear end to the front end; a bucket-shaped sound guide hole is formed in each front cover and the corresponding sound guide tube; a toning hole is vertically formed in the top of each main shell, and is positioned in the rear end of the corresponding loudspeaker; a net cover is arranged on each toning hole; the rear wall of each accommodation wall is parallel to the rear end face of the corresponding loudspeaker; the loudspeakers and the toning holes are perpendicular to the bucket-shaped sound guide holes. According to the in-ear earphone, the low-frequency reproducibility of the earphone is enhanced, ear canals of a user can be prevented from being completely isolated from the outside, potential threats are avoided, and the occurrence of a sound leakage phenomenon is prevented.

Description

technical field [0001] The invention belongs to the technical field of earphones and relates to an in-ear earphone. Background technique [0002] As an indispensable electronic equipment accessory in modern life, earphones are widely used in various fields. Due to the popularization of electronic products such as mobile phones or video players, earphones, as their supporting products, can be seen everywhere even in daily life. While it brings many conveniences to people, it also adds endless fun to life. [0003] As one of many earphones, in-ear earphones are favored by consumers due to their special sound effects. On the basis of ordinary earphones, in-ear earphones are inserted into the human ear canal with a rubber plug to obtain better Its airtightness has the advantage of providing a closed environment, which greatly enhances the performance of the earphones, reduces the interference of external noise to music, and greatly reduces sound leakage. [0004] Generally, ea...

AI Technical Summary

Problems solved by technology

[0004] Generally, earphones usually vibrate the sound unit of the earphone according to the audio signal of the player. The flow of gas inside and outside the earphone directly affects the frequency of the generated sound, so the flow of gas has a great impact on the sound quality. In-ear earphones have the advantage of low distortion. In terms of sound effect, it brings users an unprecedented sound quality experience, but the earphone is a closed space, and the gas cannot flow, so the low frequency reproducibility of this earphone is poor, and the low frequency is the most basic and most important frequency in the sound. ; but because this earphone forms a closed space between the pronunciation end and the human ear canal, and is separated from the outside world, the user often cannot hear other sounds from the outside world when listening to music. In some special environments, because the user's hearing is isolated from the outside world, there is often a greater threat to his own safety. For example, when walking on the road or crossing the road, the user cannot hear the whistle of the vehicle. , are often easy to be bumped into and cause accidents, and these phenomena are common in life; and in the existing in-ear earphones, the sound leakage is often serious due to the poor sealing of the earphones, and the sound leakage will not only affect the user's surroundings impact on people, greatly reducing the effect of earphones
