For example, the elastic connection portion 130 may be made of a rubber material. In order to facilitate the elastic connection portion 130 to generate elastic bending deformation, the outer surface of the elastic connection portion 130 is provided with a plurality of protrusions 131 and grooves 132 which are alternately concave and convex. In one embodiment, the elastic connection portion 130 is a tubular structure, the protrusions 131 and the grooves 132 on the exterior of the tubular structure may be annular, and the annular protrusions 131 and the grooves 132 are sequentially arranged along the central axis m1 of the tubular structure, so that when the elastic connection portion 130 is bent, for example, when the left end of the elastic connection portion 130 is bent upward in the state shown in fig. 1, the protrusions 131 on the upper end of the elastic connection portion 130 are close to each other and the protrusions 131 on the lower end are far from each other, thereby facilitating the bending of the elastic connection portion 130.

In one embodiment, the elastic connection portion 130 is provided with a plurality of protrusions 131 and grooves 132 with alternating concave and convex portions, the protrusions 131 and grooves 132 are not limited to the elongated embodiment shown in fig. 1, for example, the protrusions 131 and grooves 132 may also be discrete dot-shaped structures, such as convex hemispherical structures or concave hemispherical structures, and the protrusions 131 and grooves 132 make the elastic connection portion 130 more easily elastically deformed, thereby improving the flexibility of the mutual movement of the housing 100 and the sound tube 120 after being elastically connected.

In one embodiment, as shown in fig. 1, the sound tube 120 may be oscillated within a conical region with respect to the housing 100 about the central axis m1 of the tubular structure by the resilient connection 130.

In one embodiment, the sound tube 120 is made of hard plastic or metal, the housing 100 is made of hard plastic or metal, and the elastic connection 130 made of rubber is disposed between the sound tube 120 and the housing 100. The housing 100 of the earphone in this embodiment has high strength, and can protect the electronic components in the housing 100.

In one embodiment, as shown in fig. 3, the speaker 310 is disposed in the sound tube 120, and the speaker 310 can move synchronously with the sound tube 120. Specifically, the sound tube 120 is a tubular structure, for example, the sound tube 120 has a passage 121 penetrating the sound tube 120 along a center line m2 of the sound tube 120, and the speaker 310 is fixed in the passage 121. In this embodiment, the sound emitted from the speaker 310 is transmitted through the shorter channel 121 in the earphone, so that the sound loss in the earphone is reduced and the sound effect is better. The speaker 310 has a sound outlet 311, the sound outlet 311 of the speaker 310 faces and is close to the sound outlet 122 of the sound tube 120 far from the housing 100, when the sound tube 120 is inserted into the ear canal 12, the sound outlet 122 is closer to the depth of the ear canal 12, and the sound emitted from the sound outlet 311 can directly emit from the sound outlet 122 to enter the depth of the ear canal 12, and therefore, no matter how the sound tube 120 swings relative to the housing 100, the sound emitted from the sound outlet 311 of the speaker 310 can be emitted from the sound outlet 122 in a stable and shortest distance, thereby improving the sound quality of the earphone and the stability of the sound.

In some embodiments, the speaker 310 may be disposed in the housing 100, the sound duct 120 is a tubular structure, and the sound emitted from the speaker 310 is emitted through the channel 121 of the tubular sound duct 120, and since the sound duct 120 may swing within a certain range relative to the housing 100, the tubular sound duct 120 may swing toward different directions to change the sound emitting direction, so that the sound is always emitted from the sound duct 120.

It should be understood that in the above embodiments, whether the speaker 310 is disposed within the sound tube 120 or the speaker 310 is disposed within the housing 100, it means that at least a portion of the speaker 310 is disposed within the sound tube 120 or the housing 100. For example, when the speaker 310 is disposed in the sound tube 120, specifically, at least a portion of the speaker 310 is fixed in the sound tube 120, the speaker 310 moves along with the sound tube 120 when the sound tube 120 swings with respect to the housing 100; when the speaker 310 is disposed within the housing 100, specifically meaning that at least a portion of the speaker 310 is fixed within the housing 100, the speaker 310 does not move with the sound tube 120 when the sound tube 120 is swung relative to the housing 100.
