Description

Headset Technical Field The application relates to the technical field of headphones, in particular to a headset. Background Headphones are increasingly used because they are comfortable to wear and have excellent use effects. As the demands of people are also increasing, there is a higher demand for the functions of headphones. In the related technical field, when a user wears the headset, the earmuffs are usually covered on the ears of the user, so that air at the ears of the user is easy to not circulate, the user can feel stuffy and uncomfortable feeling of the ears after wearing the headset for a long time, and the user experience is reduced. Disclosure of utility model The embodiment of the application provides a headset, which aims at meeting noise reduction and ventilation requirements of users. In order to solve the technical problems, the embodiment of the application provides a headset, which comprises an earshell, a horn assembly, a mounting bracket and an opening and closing blade assembly, wherein the earshell is provided with an air hole communicated with the outside, the horn assembly is arranged in the earshell and is matched with the earshell to form a front cavity and a rear cavity, the front cavity is communicated with the rear cavity, the rear cavity is communicated with the air hole, the mounting bracket is arranged in the rear cavity and divides the rear cavity into a first subchamber and a second subchamber, the mounting bracket is provided with an opening communicated with the first subchamber and the second subchamber, the opening and closing blade assembly is arranged at the opening, the opening and closing blade assembly is movably connected with the mounting bracket and is provided with a first state and a second state, when the opening and closing blade assembly is in the first state, and when the opening and closing blade assembly is in the second state, the opening and closing blade assembly is closed.
