Embodiment 1

[0041] like figure 1 and figure 2 As shown, an earphone provided in this embodiment can be plugged into an electronic device, and includes a sound guide tube 1, a speaker unit 2, and a front shell 3 arranged between the sound guide tube 1 and the speaker unit 2. The shell 3 is a hollow shell, and the surface of the front shell 3 is formed with a first opening 3a communicating with the inside 30 of the front shell; the sound guide tube 1 has opposite first ends 1a and second ends 1b, and the surface of the front shell 3 is also formed with It communicates with the inside of the front shell 30 and allows the first end 1a of the sound guide tube 1 to extend into and extend out of the second opening 3b of the inside of the front shell 30. The circumferential side wall of the sound guide tube 1 abuts against the inner wall of the second opening 3b to close the second opening 3b. Two openings 3b, the second end 1b of the sound guide tube 1 is located outside the front shell 3, the...

Embodiment 2

[0050] Attached below image 3 Only the differences from the previous embodiments will be described in detail.

[0051] In this embodiment, the earphone also includes a hollow back shell 5 and a tuning member 6, the surface of the back shell 5 is formed with a third opening 5a, and the speaker unit 2 is arranged at the third opening 5a of the back shell 5; 6 has a relatively built-in portion 6a and an external portion 6b, and the surface of the rear shell 5 is also formed with a fourth opening 5b that communicates with the inside of the rear shell 5 and allows the built-in portion 6a to extend into and out of the rear shell 5. The inner portion 6a The outer wall contacts the inner wall of the fourth opening 5b to close the fourth opening 5b. The outer part 6b is located outside the rear case 5, and the inner part 6a and the speaker unit 2 define a sound cavity 50 inside the rear case 5 together.

[0052] When the built-in part 6a stretches into and out of the back shell 5, th...

Abstract

The invention relates to the technical field of earphones, and specifically relates to an earphone with adjustable sound quality. The earphone comprises a sound guide tube, a loudspeaker single body and a hollow front shell, and is characterized in that a first opening communicated with the interior of a front shell is formed in the surface of the front shell; the sound guide tube is provided witha first end and a second end which are opposite, a second opening which is communicated with the interior of the front shell and allows the first end of the sound guide tube to extend into and out ofthe front shell is further formed in the surface of the front shell, the circumferential side wall of the sound guide tube abuts against the inner wall of the second opening to close the second opening, and the second end of the sound guide tube is located outside the front shell; the front shell and the sound guide tube jointly define a volume-variable internal space, and the loudspeaker singlebody is arranged in the internal space and located on the first opening side; a user changes the volume of the internal space by controlling the second end of the sound guide tube, and the sound fieldwave transmission frequency can be changed by changing the volume of the front side space of the loudspeaker single body, so that the sound quality of the earphone sound is adjusted, the user can listen to different types of music conveniently, and the user experience is good.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone with adjustable sound quality. Background technique [0002] With the continuous improvement of people's requirements for the quality of earphones, the single audio output function is far from meeting the requirements of consumers. The earphone products currently on the market are fixed due to the cooperation between the front cavity and the rear cavity of the earphone, which makes the earphone leave the factory. That is, there is only one sound quality, which cannot meet the user's hearing requirements for different types of music. In order to use headphones to hear their favorite and comfortable sounds, users usually choose to purchase multiple headphones with different sound qualities, which is costly. ; Therefore, in order to meet different hearing requirements, it is necessary to study a headphone structure that can freely adjust the sound quality.
