[0015] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0016] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] See also Figure 1 , 2 , 3, 4, and 5 are schematic diagrams of preferred embodiments of the present invention. The present invention is related to a wire fixing structure of an earplug, comprising an earplug front cover 1, an earplug back cover 2, a speaker 3 disposed between the earplug front cover 1 and the earplug back cover 2, and a wire 4 connected to the speaker 3. In this embodiment, the earplug front cover 1 and the earplug back cover 2 are assembled by covering and forming an inner cavity, and the speaker 3 is positioned in the corresponding inner cavity. Furthermore, the earplug front cover 1 and the earplug back cover 2 are configured into a comma-shaped structure, and a lead wire channel 5 is also enclosed and configured between the earplug front cover 1 and the earplug back cover 2 so that the wire 4 can extend from the lead wire channel. In the present embodiment, the wire channel 5 is formed by the comma tail of the earplug front cover 1 and the earplug back cover 2, and the wire channel 5 extends upwardly tilted relative to the horizontal line to obtain a required slope. At the same time, the wire channel 5 has a self-locking structure that can change the routing direction of the wire 4 and increase the tensile resistance of the wire 4 during the assembly process of the earplug front cover 1 and the earplug back cover 2, thereby ensuring a stable connection between the wire inside the earplug and the speaker, which is not easily pulled and falls off, thereby improving the service life of the earplug. In addition, there is no need to tie a knot on the wire during assembly, nor is there any need to pre-make a bulge on the wire, thereby simplifying the assembly and production of the wire and reducing the production cost.

[0018] Figure 2 As shown, in this embodiment, the self-locking structure changes the routing direction of the wire 4 at least twice, and the amplitude of changing the routing direction of the wire 4 gradually decreases as the lead channel 5 extends in an inclined manner. The routing direction of the wire 4 is changed in accordance with the inclination of the lead channel 5 to form multiple locking lines, thereby increasing the axial tensile resistance of the wire, thereby protecting the connection between the wire 4 and the speaker 3.

[0019] Figure 2 , 3As shown in Figures 4 and 5, in this embodiment, the self-locking structure includes a first vertical plate 11 and a second vertical plate 12 erected from the front cover 1 of the earplug, and a first lower pressing plate 21 and a second lower pressing plate 22 of the rear cover 2 of the earplug; the first vertical plate 11 and the second vertical plate 12 form a front-to-back spacing relationship in the inclined extension direction of the lead-in channel 5, and the first vertical plate 11 is provided with a first U-shaped groove 111 with an upward opening, and the second vertical plate 12 is provided with a second U-shaped groove 121 with an upward opening, and the bottom of the second U-shaped groove 121 is higher than the bottom of the first U-shaped groove 111 at a height of the horizontal reference line. When the earplug front cover 1 and the earplug back cover 2 are assembled, the first vertical plate 11, the second vertical plate 12 and the first lower pressing plate 21, the second lower pressing plate 22 form an interlaced plug-in assembly, and the first lower pressing plate 21 presses down on the front side of the first vertical plate 11 to control the wire 4, so that the wire 4 climbs up and embeds into the first U-shaped groove 111 after coming out of the speaker 3, and the second lower pressing plate 22 presses down on the rear side of the first vertical plate 11 to control the wire 4, so that the wire 4 is in frictional contact with the inner side wall of the earplug front cover 1 and forms a tendency to climb up again with the second lower pressing plate 22 as the base point, and the second U-shaped groove 121 supports the wire 4 to extend from the end of the lead-in channel 5. In this way, the first vertical plate 11, the second vertical plate 12 and the first lower pressing plate 21, the second lower pressing plate 22 cooperate with each other, so that the routing direction of the wire 4 is changed multiple times when the wire 4 is led out, and the multi-line locking effect is obtained, thereby increasing the axial tensile resistance of the wire.

[0020] Figure 1 , 2 As shown in , 3, 4, and 5, in this embodiment, the end of the lead-in channel 5 is higher than the bottom of the second U-shaped groove 121 at the height of the horizontal reference line, so that the wire 4 forms an upward climbing posture from the second U-shaped groove 121 to the end of the lead-in channel 5 and frictionally contacts the inner side wall of the earplug front cover 1, thereby increasing the axial tensile resistance of the wire. The earplug front cover 1 is provided with a third U-shaped groove 13 and hanging platforms 14 distributed on the left and right sides of the third U-shaped groove 13 at the end of the lead-in channel 5. The third U-shaped groove 13 is used to guide the wire 4 to extend out, and the hanging platform 14 is used to cooperate with the hook 23 of the earplug back cover 2 to hang, which not only increases the combined connection strength between the earplug front cover 1 and the earplug back cover 2, but also ensures that the third U-shaped groove 13 stably supports the wire 4, so that the wire 4 maintains an upward climbing posture from the second U-shaped groove 121 to the end of the lead-in channel 5 and frictionally contacts the inner side wall of the earplug front cover 1.

[0021] The utility model does not need to tie a knot on the wires during assembly, nor does it need to pre-make bulges on the wires, thereby simplifying the assembly and production of the wires and reducing the production cost.

[0022] Although the preferred specific embodiments of the present invention are described above in conjunction with the accompanying drawings, the present invention should not be limited to the structures and operations that are exactly the same as the above description and the accompanying drawings. For those skilled in the art, many equivalent improvements and changes can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and changes should all fall within the scope of protection required by the present invention.
