For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood in specific situations.

In the prior art, the earphone is connected to the inside and outside through the sound outlet to realize listening. However, due to the existence of the sound outlet, the waterproof effect of the earphone itself will also be poor, resulting in the water or water mist from the outside entering the earphone, which is harmful to the earphone. Corrosion of internal electrical components reduces the service life of the headset.

In order to solve the above problems, the earphone of the present application is described below with reference to FIGS. 1 to 8 . The earphones given here can be wired earphones or wireless earphones, which are not limited. Optionally, the earphones are TWS earphones.

As shown in FIG. 1 to FIG. 4 , the earphone according to the embodiment of the present application includes: a casing 10 , a sealing cover 30 and a driving part.

The casing 10 has a sound outlet 10a; the casing 10 is a part of the structure of the earphone, which is used to cover other electrical components in the earphone, such as a wireless module and a speaker. The housing 10 communicates with the inside and the outside through the sound outlet 10a, so that the sound of the speaker can be transmitted to the outside through the sound outlet 10a to realize listening. Specifically, one end of the sound outlet 10a is connected with a speaker net, and the other end is arranged opposite to the speaker.

The sealing cover 30 is movably arranged in the casing 10; specifically, as shown in FIG. 6 and FIG. 7, the earphone further includes a bracket 20, and the bracket 20 is fixed in the casing 10; the sealing cover 30 is movably arranged in the casing On the body 10 , the bracket 20 is used as a structure for supporting the sealing cover 30 .
