[0035] Specifically, the sliding opening 143 passes through both ends of the clamping member 14. The sliding part 21 of the bracket 2 extends into one end of the sliding opening 143 and extends out from the other end. The clamping member 14 is sleeved on the outside of the sliding part 21 and fits against the sliding part 21 to prevent the sliding part 21 from shaking inside the clamping member 14 and causing the sliding part 21 to be misaligned during extension and retraction.

[0036] In some embodiments, such as Figure 2 As shown, the sliding part 21 is provided with a plurality of positioning grooves 211 along the telescopic extension direction, and the clamping member 14 is provided with positioning protrusions 142 that cooperate with the positioning grooves 211.

[0037] Specifically, the middle part of the sliding part 21 is provided with a plurality of positioning grooves 211, which are continuously distributed along the extension direction of the sliding part 21, and the clamping piece 14 is provided with a positioning protrusion 142 at a position opposite to the positioning groove 211, and the positioning groove 211 on the sliding part 21 and the positioning protrusion 142 of the clamping piece 14 form a stop buckle, which realizes the positioning of the sliding part 21 of the support 2 in the main body head beam 1, so as to ensure that the sliding part 21 can maintain the adjusted position state after the sliding adjustment on the clamping piece 14, so that the support 2 can play a role of length adjustment and positioning when being extended and retracted in the main body head beam 1.

[0038] Further, the positioning protrusion 142 can be selected but is not limited to a spherical structure, and the spherical positioning protrusion 142 can smoothly switch at different positions and form a stop buckle, thereby reducing the abnormal sound generated during the length adjustment of the support 2.

[0039] In the embodiment, the clamping piece 14 is sleeved on the sliding part 21 of the support 2 and is in sliding connection with the sliding part 21, the positioning protrusion 142 of the clamping piece 14 cooperates with the positioning groove 211 of the support 2 to realize the extension adjustment of the sliding part 21, the clamping piece 14 is provided with a swing shaft 141, the swing shaft 141 cooperates with the groove 15 in the main body head beam 1 to realize the swing of the clamping piece 14, and drives the support 2 to swing to realize the adjustment of the wearing angle.

[0040] Embodiment 2:

[0041] This embodiment is a further structural optimization of the earphone support structure of the utility model, please refer to Figure 3 .

[0042] In some embodiments, the clamping piece 14 is sleeved on the sliding part 21, the opposite two faces of the clamping piece 14 are respectively provided with a first protrusion 1411 and a second protrusion 1412, the first protrusion 1411 cooperates with the second protrusion 1412 to form a swing shaft 141.

[0043] Specifically, the top of the clamping piece 14 is provided with the first protrusion 1411, the bottom of the clamping piece 14 is provided with the second protrusion 1412, the first protrusion 1411 and the second protrusion 1412 are both arranged at the middle part of the clamping piece 14, and the first protrusion 1411 and the second protrusion 1412 cooperatively form the swing shaft 141 of the clamping piece 14. The up-and-down separated design of the swing shaft 141 shortens the swing shaft distance of the clamping piece 14, and the multiple abutting contact points also make the clamping piece 14 more stable when swinging.

[0044] In order to make the support 2 more smooth when adjusting the wearing angle, in some embodiments, the first protrusion 1411 and the second protrusion 1412 are both arc-shaped structures. The arc-shaped contact surface can make the contact area relatively stable, and the relative movement mode at the contact point is more regular during the entire rotation of the clamping piece 14, the friction between the components is more uniform, the service life of the earphone support structure is prolonged, and the arc-shaped contact surface can facilitate the installation of the clamping piece 14.

[0045] In some embodiments, the clamping piece 14 reciprocates within the main head beam 1 with a swing angle of 1-6 degrees with the swing axis 141 as the center.

[0046] It can be understood that the clamping piece 14 is limited by the internal space of the main head beam 1, and a larger rotation angle is easy to cause the main head beam 1 to have a larger cross section, greatly reducing the deformability of the main head beam 1, which is not conducive to wearing. The flat arc-shaped head beam can better fit the head curve, and the structure has a certain elasticity and can be self-adapted according to the head shape of different users. It has been proved through tests that this rotation angle not only can ensure that the comfort of most people is met when adjusting the wearing angle, but also the overall wearing of the main head beam 1 is aesthetically pleasing.

[0047] Further, the clamping piece 14 is made of POM plastic material. The clamping piece 14 can be integrally injection molded, and the positioning protrusion 142 of the clamping piece 14 is a POM plastic spring piece. When in use, the extension of the support 2 feels smooth, and the durability test of the positioning clamping point of the support 2 is more consistent, and it is not easy to produce irregular abnormal noise after long-term use. The clamping piece 14 made of POM plastic material has self-lubricating properties, which reduces wear when cooperating with the sliding part 21 of the support 2 during use, thereby increasing the service life of the clamping piece 14 and the support 2.

[0048] In the present embodiment, the clamping piece 14 is designed to form the swing axis 141 by cooperating the first protrusion 1411 and the second protrusion 1412. The swing axis 141 is separated and located on the upper and lower sides of the clamping piece 14, which not only reduces the occupied space of the clamping piece 14 in the main head beam 1, but also avoids the influence of a single rotating contact surface on the stability of the support 2. The clamping piece 14 can swing left and right within the main head beam 1 with a swing angle of 1-6 degrees with the swing axis 141 as the center, thereby achieving the effect of adjusting the wearing angle of the earphone support 2. In particular, the clamping piece 14 is made of POM plastic material, and the positioning protrusion 142 on the clamping piece 14 is a POM plastic spring piece, which can reduce the wear between components and has a simple structure, thereby reducing production costs.
