Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

An earphone 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 13. The headset 100 may be a TWS headset. In the following description of the present application, the headset 100 is exemplified as a TWS headset. Of course, those skilled in the art will appreciate that the headset 100 may also be other types of headsets 100 and is not limited to TWS headsets.

As shown in fig. 1 and 2, an earphone 100, such as a TWS earphone, according to an embodiment of the present invention includes a head band 1, two ear cups 2, and at least one earphone body 3.

Two earmuffs 2 are connected respectively at the both ends of head hoop 1, and at least one in two earmuffs 2 is the earmuff that charges, and the earmuff that charges includes the module of charging. From this, through above-mentioned setting, can hang head band 1 and use at human neck, compare with the earphone box that charges that needs carried independently now, because ear muff 2 links to each other with head band 1 and at least one ear muff 2 includes the module of charging, can prevent effectively that the module of charging from losing. Moreover, the charging module arranged in this way can be held by hands without hands, and is convenient to carry. In addition, head band 1 and ear muff 2 that the string of neck used can play better decorative effect, have higher fashion nature and aesthetic property to can effectively promote user experience. Alternatively, in conjunction with fig. 1 and 2, the head band 1 may be formed in an arc-shaped structure to fit the shape of the neck of a human body. But is not limited thereto.

Earphone body 3 detachably establishes in the earmuff that charges, and the module of charging is connected with earphone body 3 electricity in order being suitable for to earphone body 3 to charge when earphone body 3 is located the earmuff that charges. For example, in the example of fig. 10 and 11, a first charging contact 26 may be provided in the charging ear cup, and the first charging contact 26 is connected to the charging module. The earphone body 3 may be provided with a second charging contact 31. The first charging contact 26 can be connected to the second charging contact 31 when the earphone body 3 is placed in the charging muff. When the earphone 100 is determined to need to be charged, the power of the charging module is transferred to the earphone body 3 through the first charging contact 26 and the second charging contact 31.

Therefore, through the arrangement, when in use, the earphone body 3 can be taken out of the charging earmuff and put into the ear of a human body, so that the sound signal is transmitted to the ear of the human body; after the use is accomplished, can put into the corresponding earmuff that charges with earphone body 3 in, on the one hand, the module of charging in the earmuff that charges can charge earphone body 3 to improve earphone body 3's duration, on the other hand, the earmuff that charges can play effectual holding effect, can prevent effectively that earphone body 3 from losing.

In some embodiments of the present invention, referring to fig. 2, the charging earmuffs comprise an earmuff box 21 and an earmuff cover 22. Wherein the charging module is arranged in the earmuff box 21, one end of the earmuff cover 22 is rotatably connected with the earmuff box 21 to open and close the earmuff box 21, and the earphone body 3 is suitable for being put into the earmuff box 21 or taken out of the earmuff box 21 when the earmuff cover 22 opens the earmuff box 21.

For example, in the example of fig. 2, the ear cup case 21 is of a substantially cylindrical structure, the ear cup cover 22 is of a substantially circular shape, the ear cup cover 22 is provided on one side surface of the ear cup case 21, and one end of the ear cup cover 22 in the radial direction is pivotally connected to the ear cup case 21. When the earphone body 3 needs to be taken and placed, the earmuff cover 22 can rotate around the end of the earmuff cover 22 towards the side far away from the earmuff box 21, so that the earmuff box 21 is opened; when the taking and placing are completed, the earcup cover 22 is rotated around the one end of the earcup cover 22 toward the earcup box 21 to close the earcup box 21. Wherein, earphone body 3 can be fixed in earmuff box 21 through the mode of magnetism, can adopt magnetism to inhale or the mode that machinery pressed realizes opening and closing of earmuff box 21 between earmuff lid 22 and the earmuff box 21.

From this, through setting up foretell earmuff box 21 and earmuff lid 22, earmuff box 21 can be used for holding earphone body 3 to when making things convenient for earphone body 3 to charge, can prevent effectively that earphone body 3 from losing. Moreover, when the earmuff cover 22 closes the earmuff box 21, impurities such as external dust can be effectively prevented from entering the earmuff box 21, so that the influence on the normal work of the charging module can be avoided, and the service life of the charging module can be prolonged. In addition, through making ear muff lid 22 and ear muff box 21 rotationally link to each other, can need not extra spare part between ear muff lid 22 and the ear muff box 21 and be connected, the structure is simpler, makes things convenient for opening and closing of ear muff box 21 to make things convenient for getting of earphone body 3 and put.

In some embodiments of the present invention, referring to fig. 2-5, each ear cup 2 is rotatably connected to the head band 1 through a rotating structure 4, the rotating structure 4 includes a first rotating shaft 41, and each ear cup 2 is rotatable around a central axis of the corresponding first rotating shaft 41 relative to the head band 1.
