In addition, the earphone further comprises: a decorative plate, which is mounted at an end of the cover plate away from the casing and can be manually mounted to the cover plate or detached from the cover plate.

In addition, the earphone further comprises: an earplug sleeve, which is detachably sleeved on the mounting end.

The beneficial effects of the present utility model are as follows:

The earphone provided by the present utility model can adjust the in-ear angle, which improves the wearing comfort and thereby improve the sound quality of the earphone. In addition, the sound guiding tube can be manually removed from or installed to the casing, which is very convenient for users to replace the sound guiding tube or clean the earphones.

DETAILED DESCRIPTION

In order to explain the technical solutions of the present utility model more clearly and completely, the present utility model will be further described as below in conjunction with the attached drawings.

Please refer toFIG. 1toFIG. 3, the present utility model provides an earphone, wherein the earphone comprises:

a casing10, wherein a receiving cavity11is formed inside the casing10, and the casing10is provided with a first mounting hole12connecting with the receiving cavity11;

a mounting plate20, wherein the mounting plate20is fixedly mounted in the receiving cavity11and the mounting plate20completely blocks the first mounting hole12from connecting with the receiving cavity11; and one end of the mounting plate20adjacent to the first mounting hole12is provided with a sound-transmitting groove21; and
a sound guiding tube30, wherein one end of the sound guiding tube30is a movable end31, and the other end of the sound guiding tube30is a mounting end32, and a sound guiding channel33passing through the movable end31and the mounting end32is provided inside the sound guiding tube30so that when the movable end31portion is installed in the first mounting hole12the sound guiding channel33connects with the sound-transmitting groove21and the movable end31can rotate in the first mounting hole12so as to enable the sound guiding tube30to rotate relatively to the casing10; and the sound guiding tube30can be installed into the first mounting hole12or be detached from the first mounting hole12manually.

In the present embodiment, when a user wears the earphone, the in-ear angle of the earphone is adjusted by rotating the sound guiding tube30to achieve optimal wearing comfort, thereby improving the sound quality of the earphone; and in addition, the sound guiding tube30can be manually mounted into the first mounting hole12or detached from the first mounting hole12, and a user can replace the sound guiding tube30according to actual conditions, which improves wearing comfort and sound quality of the earphone to the maximum extent. The earphone provided by the present utility model can adjust the in-ear angle of the earphone, which improves the wearing comfort and thereby improve the sound quality of the earphone. In addition, the sound guiding tube30can be manually removed from or installed to the casing10, which is very convenient for users to replace the sound guiding tube30or clean the earphone.

Please refer toFIG. 1andFIG. 2. A first mounting slot24is disposed at one end of the mounting plate20away from the first mounting hole12, a first sound-transmitting hole22is disposed at a bottom of the first mounting slot24, and the first sound-transmitting hole22is in connection with the sound-transmitting groove21. A second mounting slot25is further disposed at one end of the mounting plate20away from the first mounting hole12, a second sound-transmitting hole23is disposed at a bottom of the second mounting slot25, and the second sound-transmitting hole23is in connection with the sound-transmitting groove21.

In the present embodiment, the first mounting slot24and the second mounting slot25are used to mount other components of the earphone, such as a sounding unit; wherein sound made in the receiving cavity11passes through the first sound-transmitting hole22and the second sound-transmitting hole23to be transmitted to the sound-transmitting groove21, and then transmitted by the sound-transmitting groove21to the sound guiding channel33and finally transmitted out of the earphone through the sound guiding channel33to enter a wearer's ear canals.

Please refer toFIG. 1andFIG. 3. The earphone further comprises: a cover plate40, which is fixedly connected to an end of the casing10away from the first mounting hole12. The earphone further comprises: a decorative plate50, which is mounted at an end of the cover plate40away from the casing10and can be manually mounted to the cover plate40or detached from the cover plate40.

In the present embodiment, the cover plate40is fixedly connected to the casing10, and the cover plate can effectively protect the components installed in the receiving cavity11. The decorative plate50can be manually mounted to the cover plate40or detached from the cover plate40. Thus, users can replace the decorative plate50of different styles according to their own preferences, which can meet the individual needs of users.

Please refer toFIG. 1andFIG. 3. The earphone further comprises: an earplug sleeve60, which is detachably sleeved on the mounting end32.
