Problems solved by technology

[0003] This structure can only adjust the low-frequency sound quality effect of the headset by adjusting the airflow between the front cavity and the rear cavity, the rear cavity and the outside world. Therefore, before the headset leaves the factory, technicians have limited means to adjust the sound quality of the headset; After the headset leaves the factory, users cannot adjust the sound quality of the headset according to their own preferences and needs with a high degree of freedom

Abstract

The invention provides a headphone and relates to the field of headphones. The earphone comprises at least one earshell with a partition installed, a speaker assembly is installed on the partition, the speaker assembly and the partition together separate the earshell where it is located into a front cavity and a rear cavity, and the partition has at least one acoustic short-circuit channel Each acoustic short-circuit channel group includes: a first channel connecting the front cavity and a rear cavity; a second channel connecting the first channel and the outside world. The earphone realizes the simultaneous adjustment of the air flow between the front chamber, the rear chamber and the outside world, and can more flexibly change the low-frequency sound quality effect of the earphone.

Description

technical field [0001] The invention relates to the field of earphones, in particular to an earphone. Background technique [0002] In the existing technology, such as figure 1 As shown, the closed headphone generally has two ear shells, and each ear shell has an acoustic short-circuit hole 10 communicating with the front cavity and the rear cavity, and a transparent hole opened on the back shell of the ear shell and communicating with the rear cavity and the outside world. Sound hole 20. Changing the opening size of the sound short-circuit hole 10 and the sound-transmitting hole 20 and pasting tuning papers with different thicknesses on them can change the air flow in the earphone shell, thereby adjusting the frequency response of the earphone and changing the low-frequency sound quality of the earphone . [0003] This structure can only adjust the low-frequency sound quality effect of the headset by adjusting the airflow between the front cavity and the rear cavity, the...
