Abstract

The invention provides an earphone, which comprises a shell, an earphone line, a speaker single body and a line knot fixing member, wherein the speaker single body is accommodated in the shell and connected with the earphone line, and the line knot fixing member is arranged in the shell. The earphone is characterized in that the side, which is away from the speaker single body, of the line knot fixing member is provided with a first gap; a first cavity is formed between the line knot fixing member and the speaker single body, and a second cavity is formed between the first gap and the shell; the line knot fixing member is provided with a low-pitch pipe and a connecting channel which connects the first cavity and the second cavity; and the low-pitch pipe is connected with the first cavity and isolated from the second cavity. By using the earphone provided by the invention, the intermediate frequency of the earphone can be adjusted by using the double rear acoustic cavities, and the acoustic performance of the earphone is improved correspondingly.

Description

technical field [0001] The invention relates to the technical field of acoustics, and more specifically, relates to an earphone with double rear acoustic cavities. Background technique [0002] With the wide application of high-quality smart phones, Pads and other portable electronic products, people have higher and higher requirements for earphones that can be used in conjunction with them. While requiring them to be small in size, they are also required to be able to reproduce various sound effects realistically. High-fidelity sound quality performance. In addition, regardless of the above-mentioned electronic products, in order to allow users to listen to the sound signals provided by the electronic products without disturbing others, earphones have become a necessary accessory for each electronic product. In addition, earphones also provide better sound for the listener. Transmission, so that the listener can clearly hear and understand the sound content. [0003] At p...
