[0021] The present invention is further described below with reference to the drawings.

[0022] In order that the objectives, technical schemes and advantages will become more apparent, the present invention will be described in more detail with reference to the drawings and examples above. It should be understood that the specific embodiments described herein are only for illustrating but not for limiting the present invention.

[0023] With reference to Figs. 1 and 2, a view of an earphone 1 in a first specific embodiment is illustrated. The earphone 1 is an in-ear earphone. The earphone 1 comprises an earplug cap 10, a front case 20, a rear case 30 and an earphone cover 50. Among them, the earplug cap 10 is set on one end of the front case 20, the front case 20 cooperating with the rear case 30 to form a sound chamber and a cavity for accommodating other circuit components of the earphone.

[0024] With reference to Figs. 3 and 4, a view of the earphone cover 50 is illustrated. The earphone cover 50 includes a sleeve portion 51 and a fixing portion 52. The sleeve portion 51 is configured to set the earphone cover 50 on the front case 20. The fixing portion 52 surrounds the sleeve portion 51. The sleeve portion 51 extends through the fixing portion 52. The fixing portion 52 includes a first end portion 521 and a second end portion 522 opposite to the first end portion 521. Preferably, a spherical radius of the first end portion 521 is larger than a spherical radius of the second end portion 522. Specifically, the fixing portion 52 has an egg shape. The distance between the sleeve portion 51 and the first end portion 521 is smaller than the distance between it and the second end portion 522. The sleeve portion 51 further includes a front side 523 and a rear side 524 opposite to the front side 523. Among them, the front side 523 faces the earplug cap 10, i.e., toward the ear; the rear side 524 faces the rear case 30. The aperture of the sleeve portion 51 on the front side 523 is larger than the aperture of the sleeve portion 51 on the rear side 524 and larger than the maximum diameter of the body of the front case 20. Therefore, when the earphone cover 50 is set on the front case 20, there is a certain gap 527 between the earphone cover 50 and the front case 20 (see Fig. 6).

[0025] With reference to Fig. 7, the fixing portion 52 is provided with a hollow cavity 528. The cavity 528 is connected with the sleeve portion 51 thoroughly. The earphone cover 50 is made of a soft material such as elastic silica gel.

[0026] With reference to Fig. 5, a view of the earphone 1 in use state in a third embodiment is illustrated. With reference to Fig. 6 together, a section view of the earphone 1 in use state in a third embodiment is illustrated. When the earphone 1 is inserted into the user's ear 100, the earphone cover 50 abuts the ear bone 110. Specifically, the front side 523 of the earphone cover 50 abuts the ear bone 110 such that the front side 523 is forced to deform toward the rear side 524, while the first end portion 521 and the second end portion 522 are snapped onto the ear bone 110. Specifically, the ear bone 110 includes a tragus 111 and an antitragus 112, and the first end portion 521 abuts the tragus 111; the second end portion 522 abuts the antitragus 112. Moreover, the second end portion 522 and the ear bone 110 may form at least two snapping points 200. Specifically, the second end portion 522 includes an upper portion corresponding to a crus helix and a lower portion corresponding to a cavitas conchae; when the second end portion 522 is snapped on the ear bone 110, the upper portion forms at least one snapping point 220 with the crus helix, and the lower portion forms at least one snapping point 200 with the cavitas conchae. At the same time, the first end portion 521 is also snapped on the ear bone 110 to form at least one snapping points 200, i.e., the first end portion 521 may form a snapping point 200 at the tragus. When the top 525 and the bottom 526 of the earphone cover 50 abut against the ear bone 110, the air in the cavity 528 is squeezed out of the gap 527. Therefore, the earphone cover 50 may be adjusted in shape according to the pressure (i.e., the longitudinal distance of the user's cavitas conchae). Thus, the earphone cover 50 may be applied to multiple users.

[0027] Furthermore, with at least three snapping points formed, the earphone cover 50 secures the earphone 1 to the ear bone 110 so that the earphone 1 may not fall off easily. In addition, the earphone 1 is more closely fitted to the human ear 100, and the possibility of sound leakage is greatly reduced.

[0028] With reference to Fig. 8, a view of the earphone cover 50 according to a second specific embodiment is illustrated. In the second embodiment, the fixing portion 52 of the earphone cover 50 has a solid structure, and the sleeve portion 51 is a circular through hole penetrating the fixing portion 52. That is, the aperture of the sleeve portion 51 on the front side 523 is larger than the aperture of the sleeve portion 51 on the rear side 524.

[0029] The earphone cover provided not only makes it easier to fit the ear cavity by virtue of its smooth surface, but also has more contact points with the ear cartilage, thereby achieving the effect of homogenizing pressure without puncturing the human ear cartilage.

[0030] With reference to Fig. 9, a view of the earphone cover 50 according to a third specific embodiment is illustrated. In the third embodiment, the fixing portion 52 of the earphone cover 50 is further provided with at least one through hole 529. The through hole 529 has a crescent shape. Specifically, the through hole 529 is defined in the first end portion 521 and the second end portion 522 of the fixing portion 52.

[0031] With reference to Fig. 10, a view of the earphone 1 in use state in the third embodiment is illustrated. When the earphone cover 50 abuts the ear bone 110, the first end portion 521 and the second end portion 522 are pressed by the ear bone such that the through hole 529 at the both end portions is deformed. Thus, the first end portion 521 and the second end portion 522 may not cause too much pressure on the ear bone. The earphone 1 may be fixed in the human ear without puncturing the ear bone of the human ear.

[0032] The earphone cover provided is deformed when receiving the pressure, and the telescopic expansion of the earphone cover is realized by deformation. Therefore, the earphone cover may weaken the pressure on the ear cavity caused by the earphone during use.

[0033] The foregoing is only preferred exemplary embodiments and is not intended to be limiting of the present invention. The scope of the invention is defined by the appended claims.
