Description

Technical Field

[0001] This utility model belongs to the field of headphone technology, specifically a wiring structure for a headphone stand. Background Technology

[0002] Headphones typically use two independent earcups, each housing a speaker structure to achieve a stereo effect. To ensure audio synchronization between the left and right ear speakers, the two earcups need to be connected by a physical cable.

[0003] Current technology for over-ear headphones increasingly adopts concealed wiring, hiding the wires inside the headphone shell. This not only improves the appearance but also protects the wires. In headphone structures with rotatable earcups, retaining the original headphone size and design with a large inner diameter for easy wire routing results in a thinner inner wall of the headphone shell. This makes the headphone prone to gradual deformation during frequent elastic deformation, making it unable to recover. Conversely, reducing the inner diameter of the mounting channel to a smaller hole structure, the existing one-piece injection molding process leads to a higher rate of hole blockage, affecting wiring quality and requiring post-processing, which severely impacts production efficiency. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a wiring structure for a headphone bracket.

[0005] The technical solution adopted by this utility model is as follows: A headphone bracket wiring structure includes earcups, headband, and a rotating connector. The rotating connector includes a wire sleeve and an upper cover and a lower cover that fit together. After the upper cover and the lower cover are closed, a wire channel for accommodating wires is formed.

One end of the wire sleeve is snapped into the upper cover, and the other end passes through the first opening and extends to the outside of the first connecting part. A wire hole is formed in the center of the wire sleeve for the wire to pass through.

[0006] In a preferred embodiment, the outer wall surface of the wire sleeve protrudes along its length to form a limiting block that is adapted to and engages with the first opening. The outer diameter of the wire sleeve is the same as the diameter of the first opening. The end of the wire sleeve located inside the upper cover protrudes to form a positioning ring, and the outer diameter of the positioning ring is larger than the diameter of the first opening.

[0007] In a preferred embodiment, the end edge of the wire-passing hole located inside the upper cover is provided with an arc-shaped chamfer for guiding the wire into the hole, and the outer diameter of the wire-passing hole is larger than the outer diameter of the wire.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] A wiring structure for a headphone stand, referring to Figure 1-5The device includes earmuffs 20, headbands 30, and a rotating connector 10. The rotating connector 10 includes a wire sleeve 15 and an upper cover 12 and a lower cover 11 that fit together. When the upper cover 12 and the lower cover 11 are closed, they form a wire channel 14 for receiving wires. The upper cover 12 includes a first connecting part 122 and a second connecting part 121 that are integrally formed. The first connecting part 122 has a first opening 123 that communicates with the wire channel 14. One end of the wire sleeve 15 is engaged inside the upper cover 12, and the other end passes through the first opening 123 and extends to the outside of the first connecting part 122. The center of the wire sleeve 15 has a center for the wire to pass through. The wire hole 152 is designed with a detachable upper cover 12 and a lower cover 11 for the rotating connector. The wire (not shown in the figure) can be hidden in the wire channel 14, which can protect the wire. At the same time, a wire sleeve 15 that can be manufactured separately is designed at the outlet of the wire channel 14. The wire sleeve 15 is used as the wire exit structure. The wire sleeve 15 and the upper cover 12 can be injection molded separately. Compared with the traditional one-piece injection molding process, it can effectively avoid the situation of the upper cover 12 blocking the hole during injection molding. While realizing convenient wiring, it can reduce the molding defect rate of parts.

[0024] Reference Figure 4 As shown, the wire hole 152 located inside the upper cover 12 has an arc-shaped chamfer 154 on one end edge for guiding the wire into the hole. The outer diameter of the wire hole 152 is larger than the outer diameter of the wire. The arc-shaped chamfer 154 is designed to facilitate the wire to be led out of the wire sleeve 15 without increasing the extra size of the wire hole 152.

[0025] Reference Figure 4 and Figure 5 As shown, a limiting block 153 that fits and engages with the first opening 123 is formed on the outer wall surface of the wire sleeve 15 along its length direction. The outer diameter of the wire sleeve 15 is the same as the diameter of the first opening 123. A positioning ring 151 is formed on the end of the wire sleeve 15 located inside the upper cover 12. The outer diameter of the positioning ring 151 is larger than the diameter of the first opening 123. The limiting block 153 can help limit the position of the wire sleeve 15 in the first opening 123, preventing the wire sleeve 15 from rotating on its own. It can also serve as an auxiliary limiting structure for the maximum rotation angle of the subsequent rotating connector 10.

[0026] Reference Figure 2 and Figure 3As shown, a rotating mounting groove 125 is recessed in the first connecting part 122. Two wire sleeves 15 are arranged opposite each other on both sides of the rotating mounting groove 125. Headband 30 is provided with headband connecting seats 40 at both ends. One end of the headband connecting seat 40 is disposed in the rotating mounting groove 125 and is rotatably connected to the wire sleeve 15. The bottom end of the rotating mounting groove 125 is recessed downward to form a groove 124. An elastic pad 13 is embedded in the groove 124, partially protruding out of the groove 124. The elastic pad 13 abuts against the outer wall surface of the headband connecting seat 40. During the rotation of the headband connecting seat 40 and the first connecting part, the damping silicone pad always generates sliding friction with the outer wall of the headband connecting seat. In this embodiment, the elastic pad 13 is made of silicone material. In other embodiments, the elastic pad 13 can also be made of rubber or other elastic materials.

[0027] Furthermore, the rotating connector 10 has a "C" shaped cross-section, and the end of the rotating connector 10 away from the headband 30 forms a clamping groove for rotating and clamping the earmuff 20.

[0028] It should be noted that the earcups 20 and headband 30 have pre-drilled channels for threading (not shown in the figure), which will not be elaborated on here.

[0029] Furthermore, the lower cover 11 includes a third connecting part 112 and a fourth connecting part 111 integrally formed. There are two fourth connecting parts 111, which are disposed opposite to each other at both ends of the third connecting part 112. The end of the fourth connecting part 111 away from the third connecting part 112 is provided with a connector 114 that connects to the ear cup 20. The connector 114 has a second opening that communicates with the wire channel 14. The second opening is designed to allow the wire to be introduced from inside the ear cup 20 into the wire channel 14, and then introduced into the other ear cup 20 along the wire channel 14.

[0030] Furthermore, there are two second connecting parts 121, which are symmetrically arranged at both ends of the first connecting part 122. The shape of the second connecting part 121 matches the shape of the fourth connecting part 111, and the shape of the third connecting part 112 matches the shape of the first connecting part 122. Before the cover is closed, the wire is first buried in the fourth connecting part 111, and then the second connecting part 121 is covered in the preset position, thereby completing the wiring operation in the upper cover 12 and the lower cover 11.

[0031] Furthermore, the lower cover 11 is provided with a plurality of positioning posts 113 having positioning holes at intervals, and the upper cover 12 is integrally provided with a plurality of positioning protrusions that are adapted to be inserted into the positioning posts. Through the cooperation of the positioning posts 113 and the positioning protrusions, the combined strength between the lower cover 11 and the upper cover 12 can be improved, and the force can be evenly distributed at each position. In this embodiment, the lower cover 11 and the upper cover 12 are fastened together by a plurality of screws. In other embodiments, such as bonding or other fixing methods can also be used, which are not limited here.

[0032] Furthermore, when the wire sleeve 15 is engaged at the extreme position of the first opening 123, one end of the positioning ring 151 is tightly abutted against the edge of the first opening 123. The lower cover 11 is also integrally provided with a plurality of reinforcing ribs 115, one end face of which abuts against the other end of the positioning ring 151. The reinforcing ribs 115 can improve the strength of the lower cover 11 itself, and can also serve as an auxiliary positioning part for the wire sleeve 15.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
