[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figure 1 As shown, the present application provides a neckband assembly 10 , which includes a wire assembly 100 and a protective outer layer 200 .

[0037] Combination Figure 2 and Figure 3 The wire assembly 100 includes a support wire 110, a first inner shell 120 and a second inner shell 130. The support wire 110 is the main supporting structure of the neckband assembly 10, and the support wire 110 is an open-loop arc structure that can be put on the user's neck; wherein the two ends of the support wire 110 are respectively connected to the first inner shell 120 and the second inner shell 130.

[0038] The support wire 110 is a memory steel wire, so that the support wire 110 can be restored after deformation.

[0039] Specifically, a first bending portion 111 is provided at the first end of the supporting wire 110, a second bending portion 112 is provided at the second end of the supporting wire 110, a limiting hole 121 is provided inside the first inner shell 120, and a limiting groove 131 is provided inside the second inner shell 130. The first end of the supporting wire 110 is inserted into the first inner shell 120 and the first bending portion 111 is inserted into the limiting hole 121, the second end of the supporting wire 110 is inserted into the second inner shell 130 and the second bending portion 112 is inserted into the limiting groove 131, and the second end of the supporting wire 110 is directly or indirectly fixed to the second inner shell 130 by adhesive.

[0040] It can be understood that the first end of the support wire 110 is passed through the interior of the first inner shell 120 and the first bent portion 111 is passed through the limiting hole 121, so that the first end of the support wire 110 can be connected to the first inner shell 120; the second end of the support wire 110 is passed through the second inner shell 130 and the second bent portion 112 is passed through the limiting groove 131, and under the action of the glue, the second end of the support wire 110 can be connected to the second inner shell 130.

[0041] Specifically, after the first bent portion 111 of the supporting wire 110 is inserted into the limiting hole 121 of the first inner shell 120, under the action of the hole wall of the limiting hole 121, the supporting wire 110 and the first inner shell 120 can be limited to prevent the supporting wire 110 from being pulled out of the first inner shell 120; after the second bent portion 112 of the supporting wire 110 is inserted into the limiting groove 131 of the second inner shell 130, the supporting wire 110 can be prevented from being pulled out of the second inner shell 130, and, under the action of the glue, the second end of the supporting wire 110 can be fixed to prevent the supporting wire 110 and the second inner shell 130 from relative movement.

[0042] More specifically, a first through hole is provided at the end of the first inner shell 120, and the first end of the supporting wire 110 can pass through the first through hole into the first inner shell 120; a second through hole is provided at the end of the second inner shell 130, and the second end of the supporting wire 110 can pass through the second through hole into the second inner shell 130.

[0043] It should be noted that the first inner shell 120 is assembled from two half shells. Before the two half shells are assembled, the first end of the supporting wire 110 can be inserted into the half shell with the limiting hole 121, and then the first end of the supporting wire 110 is bent to form a first bending portion 111, and the first bending portion 111 is extended into the limiting hole 121, and then the other half shell is assembled.

[0044] Similarly, the second inner shell 130 is also assembled from two half shells. Before the two half shells are assembled, the second end of the supporting wire 110 can be inserted into the half shell with the limiting groove 131, and then the second end of the supporting wire 110 is bent to form a second bending portion 112, and the second bending portion 112 is extended into the limiting groove 131, and then the other half shell is assembled.

[0045] like Figure 3 As shown, the direction in which the second end of the supporting wire 110 penetrates into the second inner shell 130 is defined as a preset direction, and the length of the limiting groove 131 along the preset direction is greater than the diameter of the second bending portion 112 .

[0046] It can be understood that the preset direction is the same as the axial direction of the second through hole, and the second end of the supporting wire 110 is inserted into the interior of the second inner shell 130 along the preset direction. Before the second end of the supporting wire 110 is fixed to the second inner shell 130 with glue, since the length of the limiting groove 131 along the preset direction is greater than the diameter of the second bending portion 112, the second end of the supporting wire 110 can still be moved relative to the second inner shell 130 along the preset direction. In this way, the positional relationship between the second inner shell 130 and the supporting wire 110 can be adjusted.

[0047] For example, by moving the second inner shell 130 relative to the second end of the support wire 110 in a preset direction, the length of the support wire 110 between the second inner shell 130 and the first inner shell 120 can be lengthened, and by moving the second inner shell 130 relative to the second end of the support wire 110 in a direction opposite to the preset direction, the length of the support wire 110 between the second inner shell 130 and the first inner shell 120 can be shortened. In this way, before the support wire 110 and the second inner shell 130 are fixed with the adhesive, the length of the support wire 110 between the second inner shell 130 and the first inner shell 120 can be adjusted, thereby ensuring that the length of the support wire 110 between the second inner shell 130 and the first inner shell 120 is within a predetermined range.

[0048] like Figures 1 to 3 As shown, the protective outer layer 200 is injection molded outside the line assembly 100, and two ends of the protective outer layer 200 respectively wrap at least a portion of the first inner shell 120 and at least a portion of the second inner shell 130.

[0049] Specifically, the protective outer layer 200 is formed on the outside of the line component 100 by injection molding, and the protective outer layer 200 plays a protective role on the line component 100; wherein, the protective outer layer 200 can directly contact the user's skin, and the material of the protective outer layer 200 is preferably a skin-friendly material to reduce its adverse effects on the user's skin.

[0050] During the production process of the neckband assembly 10 of the utility model, when assembling the wire assembly 100, the position of the second inner shell 130 can be adjusted to ensure that the length of the support wire 110 between the second inner shell 130 and the first inner shell 120 is within a predetermined range, meeting the requirements of the process of injection molding the protective outer layer 200 for the overall length of the wire assembly 100. In this way, it can be ensured that the wire assembly 100 can be normally placed in the mold cavity after assembly, thereby reducing the risk of leakage when the protective outer layer 200 is subsequently injected outside the wire assembly 100.

[0051] Figure 5 A measuring fixture 20 is shown, which has a lower limit measuring groove 21 and an upper limit measuring groove 22, wherein the dimensions of the lower limit measuring groove 21 and the upper limit measuring groove 22 are accurately fixed. Figure 6 and Figure 7 When the first inner shell 120 and the second inner shell 130 at both ends of the wire assembly 100 can be normally placed in the lower limit measuring slot 21 or the upper limit measuring slot 22, it means that the overall length of the wire assembly 100 meets the requirements. By adjusting the position of the second inner shell 130 relative to the support wire 110, the wire assembly 100 can be easily placed in the lower limit measuring slot 21 and the upper limit measuring slot 22, so that the tolerance of the wire assembly 100 is controlled within the allowable range, the operation is simple, and misjudgment can be reduced.

[0052] like Figure 3 As shown, in some embodiments, the angle between the depth direction of the limiting groove 131 and the preset direction is between 60° and 120°. In this way, the two side walls of the limiting groove 131 along the preset direction can effectively limit the second bending portion 112, so that when the adhesive used to bond the support wire 110 and the second inner shell 130 fails, the risk of the second end of the support wire 110 being pulled out can also be reduced.

[0053] It is understandable that the smaller the angle between the depth direction of the limiting groove 131 and the preset direction, the easier it is for the second end of the supporting wire 110 to be pulled out of the second inner shell 130 after the adhesive used to bond the supporting wire 110 and the second inner shell 130 fails. Specifically, when the angle between the depth direction of the limiting groove 131 and the preset direction is 10°, the side wall of the limiting groove 131 close to the second through hole will be relatively flat, causing the second bent portion 112 to easily come out of the limiting groove 131.

[0054] In some embodiments, the edge of the notch of the limiting groove 131 has a chamfered structure. In this way, when the support wire 110 rubs against the edge of the notch of the limiting groove 131, the wear effect of the edge of the notch of the limiting groove 131 on the support wire 110 can be reduced, thereby increasing the service life of the support wire 110.

[0055] The chamfered structure may be a rounded structure or a beveled structure.

[0056] like Figure 4 As shown, in some embodiments, the second inner shell 130 includes a first half shell 130a and a second half shell 130b detachably connected to the first half shell 130a, a limiting groove 131 is formed on the inner wall of the first half shell 130a, the first half shell 130a is provided with a positioning column 132, and the second half shell 130b is provided with a positioning hole 133, and the positioning column 132 is penetrated in the positioning hole 133. In this way, when assembling the first half shell 130a and the second half shell 130b, the positioning column 132 can be firstly penetrated into the positioning hole 133, so as to ensure the positioning accuracy of the first half shell 130a and the second half shell 130b.

[0057] The first half shell 130 a is provided with a plurality of positioning posts 132 arranged at intervals, and the second half shell 130 b is provided with a plurality of positioning holes 133 arranged at intervals. The plurality of positioning posts 132 are passed through the plurality of positioning holes 133 in a one-to-one correspondence.

[0058] Specifically, the number of the positioning posts 132 is the same as the number of the positioning holes 133 , and the plurality of positioning posts 132 corresponds to the plurality of positioning holes 133 one by one, and the positioning posts 132 are inserted into the corresponding positioning holes 133 .

[0059] Furthermore, the first half shell 130a is further provided with a first clamping portion 134, and the second half shell 130b is further provided with a second clamping portion 135, and the first clamping portion 134 is clamped with the second clamping portion 135, so that the first half shell 130a and the second half shell 130b are detachably connected. In this way, the first half shell 130a and the second half shell 130b are fixed by clamping, which is convenient for assembly and disassembly, and no other fasteners are required.

[0060] Specifically, the first clamping portion 134 is a clamping groove formed in the first half shell 130a, and the second clamping portion 135 is a buckle formed in the second half shell 130b, and the buckle is clamped into the clamping groove. In other embodiments, the first clamping portion 134 can be a buckle formed in the first half shell 130a, and the second clamping portion 135 can be a clamping groove formed in the second half shell 130b.

[0061] Combination Figure 2 and Figure 3In some embodiments, the wire assembly 100 further includes a wire 140 arranged in parallel with the support wire 110, and both ends of the wire 140 are respectively inserted into the first inner shell 120 and the second inner shell 130, and the protective outer layer 200 also wraps the wire 140. When assembling the wire assembly 100, by adjusting the position of the second inner shell 130, it can be ensured that the length of the support wire 110 and the wire 140 between the second inner shell 130 and the first inner shell 120 is within a predetermined range, meeting the requirements of the process of injection molding the protective outer layer 200 for the overall length of the wire assembly 100. In this way, it can be ensured that the wire assembly 100 can be normally placed in the mold cavity after assembly, thereby reducing the risk of the wire 140 being exposed when the protective outer layer 200 is subsequently injection molded outside the wire assembly 100.

[0062] Furthermore, the wire assembly 100 further includes a first fastener 150 and a second fastener 160, wherein the first fastener 150 is disposed inside the first inner shell 120 and fastens the wire 140 and the support wire 110 together, and the second fastener 160 is disposed inside the second inner shell 130 and fastens the wire 140 and the support wire 110 together. The first fastener 150 can also prevent the support wire 110 and the wire 140 from being pulled out of the first inner shell 120, and the second fastener 160 can also prevent the support wire 110 and the wire 140 from being pulled out of the second inner shell 130.

[0063] In some embodiments, adhesive may be disposed on the outside of the wire 140 , and the adhesive may be connected to the second inner shell 130 , so as to fix the wire 140 and the support wire 110 to the second inner shell 130 .

[0064] In other embodiments, glue may also be injected into the limiting groove 131 to fix the second bending portion 112 of the supporting wire 110 .

[0065] The present application also provides a neck-worn headset, comprising the neckband assembly 10 as described above.

[0066] The neckband headset of the present invention has the above-mentioned neckband assembly 10. During the production process of the neckband assembly 10, when assembling the line assembly 100, the position of the second inner shell 130 can be adjusted, so as to ensure that the length of the support wire 110 between the second inner shell 130 and the first inner shell 120 is within a predetermined range, and meet the requirements of the process of injection molding the protective outer layer 200 for the overall length of the line assembly 100. In this way, it can be ensured that the line assembly 100 can be normally placed in the mold cavity after assembly, thereby reducing the risk of leakage when the protective outer layer 200 is subsequently injected outside the line assembly 100.
