It should be understood that the specific embodiments described here are only used to explain the present invention, but not used to limit the present invention.

Refer to FIG. 1, which is a schematic structural diagram of an earphone in an embodiment of the present invention, and FIG. 11 is a perspective view of the earphone shown in FIG. 1. The earphone includes a main housing 100, a mouthpiece 300, a long shaft 200, and an ear cap 400. The mouthpiece 300 has a cylindrical structure, a speaker 600 is arranged in the main housing 100, and the output end of the speaker 600 is connected to the mouthpiece 300. The main housing 100 is a revolving body with a second central shaft 110, the mouthpiece 300 is connected to the main housing 100 and used to output sound, and the mouthpiece 300 is a revolving body with a first central shaft 310, the second central shaft 110 and The first central axis 310 coincides. Among them, the body of revolution is a three-dimensional curved surface, which can include a cylinder, a cone, a sphere, a torus, etc. For example, a cylinder is formed by rotating a line parallel to the axis of rotation 360° around the axis of rotation. In this embodiment, the main housing 100 and the mouthpiece 300 are both rotating bodies, and the second central axis 110 and the first central axis 310 overlap, so this structure is the same as the technology in which the mouthpiece 300 is arranged obliquely on the main housing 100 Compared with the scheme, it is simpler and the mold making method is simpler, which reduces the difficulty of manufacturing.

In some embodiments, the main housing 100 may be a revolving body, or it may not be a revolving body. For example, the cross section of the main housing 100 may be elliptical. When the main housing 100 is a cylinder, the rotation axis of the cylinder is the second central axis 110.

In some embodiments, the first central axis 110 and the second central axis 310 may be coaxially arranged.

Fig. 2 shows a schematic structural diagram of the ear. The ear canal 11 is inclined inward. In the traditional way, the technical solution of obliquely setting the sound mouth 300 on the main housing 100 is to fit the inclined ear canal 11, and the present invention Since the second central axis 110 and the first central axis 310 coincide, that is, the mouthpiece 300 of the earphone in the present invention is not obliquely arranged on the main housing 100, so the main housing 100 of the earphone in the present invention is adapted to When the inclined ear canal 11 is worn, the main housing 100 is inclined.

Continuing to refer to FIG. 2, the ear also includes a tragus 12 and an antitragus 13. The tragus 12 refers to a protrusion outside the ear canal 11 and is composed of cartilage that can cover the ear canal 11. The tragus 12 has a relatively flat inner surface. The position opposite to the tragus 12 also has a protrusion called the antitragus 13, and the inner surface of the antitragus 13 is usually slightly bulged. A depression is formed between the tragus 12 and the antitragus 13, which is called a cutout 14 formed between the tragus 12 and the antitragus 13. The cutout 14 has a larger upper port diameter and a smaller lower port diameter.

In order to improve wearing comfort and wearing firmness, the long rod part 200 is connected to the main housing 100. The cross section of the long rod part 200 perpendicular to the extending direction of the long rod part 200 is a flat structure, as shown in Figures 11 and 12 The direction Y is the extending direction of the long rod portion 200. As shown in FIG. 1, the flat structure is provided with a first plane 210 for abutting against the tragus 12 when worn along its long axis direction L, and a clamp between the first plane 210 and the vertical surface of the first central axis 310 The angle is α, and α is 15°-40°. With reference to FIG. 2, the long rod 200 can be inserted into the cutout 14 between the tragus 12 and the antitragus 13 when the earphone is worn.

In one embodiment, the long rod portion 200 extends along a linear direction, and the extension along the linear direction specifically refers to that a cross section of the long rod portion 200 is a flat structure, and the flat structure scans along the linear direction. The long rod part 200 is formed. Further, the angle between the extending direction of the long rod portion 200 and the first central axis 310 is 85° to 95°, so that the long rod portion 200 is substantially perpendicular to the first central axis.

In one embodiment, as shown in FIG. 1, the long rod part 200 is connected to the main housing 100, and the cross section of the long rod part 200 perpendicular to the extending direction of the long rod part 200 is a flat structure. The angle between the structure along its long axis direction L and the vertical surface of the first central axis 310 is β, β is 15°-40°, and the long rod portion 200 can be inserted into the tragus 12 when the earphone is worn. And the incision 14 between the tragus 13. Preferably, β is 20° to 30°.

When the earphone is worn, the outer surface 220 abuts against the tragus 13, specifically, the flat structure The outer surface 220 abuts against the inner surface of the tragus 13. Since the inner surface of the antitragus 13 is slightly bulged, the outer surface 220 may be flat, so that the tragus 12 and the antitragus 13 firmly clamp the long rod 200.

In other embodiments, the outer surface 220 of the flat structure may also be a curved surface. Fig. 3 and Fig. 4 are schematic diagrams of the structure of earphones in two embodiments, respectively. As shown in FIG. 3, the convex surface may be convex.
