Description

Technical Field

[0001] This utility model relates to the field of dual microphone cables, and more particularly to a flexible dual microphone cable. Background Technology

[0002] As a crucial solution in the professional audio acquisition field, the cable structure design of dual-microphone pickup systems directly impacts user experience and equipment reliability. Currently, dual-microphone harnesses on the market generally use independently insulated wires of 2.4-3.5mm diameter arranged in parallel, covered by a PVC / PU sheath. Existing harnesses lack self-retrieval functionality, and haphazardly tangled audio cables can easily affect sound quality. Utility Model Content

[0003] The purpose of this invention is to provide a flexible dual-microphone cable to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A flexible dual-microphone cable includes a wire core, an insulating sheath, a copper wire braided shielding layer, an insulation layer, an aluminum film shielding layer, a filling and shock-absorbing layer, an arc-shaped pre-drilled groove, a cable sheath, and horizontal cuts. The wire core is wrapped around the outer edge of an insulating sheath, the insulating sheath is wrapped around the outer edge of a copper wire braided shielding layer, the copper wire braided shielding layer is wrapped around the outer edge of an insulation layer, the insulation layer is wrapped around the outer edge of an aluminum film shielding layer, and the aluminum film shielding layer is wrapped around the outer edge of a filling and shock-absorbing layer. The filling and shock-absorbing layer has arc-shaped pre-drilled grooves at both the top and bottom. The filling and shock-absorbing layer and the two arc-shaped pre-drilled grooves are all wrapped around the outer edge of a cable sheath. The cable sheath has horizontal cuts at both the top and bottom, and can be spirally stacked through the horizontal cuts.

[0006] Preferably, the flexible dual microphone cable also includes magnetic blocks. Several magnetic blocks are equidistantly installed inside the cable sheath located in the upper and lower arc-shaped reserved slots. The magnetic blocks are located in the upper and lower horizontal cuts respectively, and can be arranged by mutual attraction between the internal magnetic blocks when the cable is spirally stacked.

[0007] The beneficial effects of this utility model are: this utility model has a reasonable design, with built-in multi-layer shielding and protective layers, and good thermal insulation performance, which can adapt to low-temperature working environments, and can be spirally stacked for easy storage.

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0011] like Figure 1 As shown, a flexible dual-microphone cable includes a wire core 1, an insulating sheath 2, a copper wire braided shielding layer 3, a heat insulation layer 4, an aluminum film shielding layer 5, a filling and shock-absorbing layer 6, an arc-shaped reserved groove 7, a cable sheath 8, and a horizontal cut 9. The outer perimeter of the wire core 1 is wrapped with the insulating sheath 2. The outer perimeter of the insulating sheath 2 is wrapped with the copper wire braided shielding layer 3. The outer perimeter of the copper wire braided shielding layer 3 is wrapped with the heat insulation layer 4. The outer perimeter of the heat insulation layer 4 is wrapped with the aluminum film shielding layer 5. The outer perimeter of the aluminum film shielding layer 5 is wrapped with the filling and shock-absorbing layer 6. The top and bottom of the filling and shock-absorbing layer 6 are provided with arc-shaped reserved grooves 7. The outer perimeter of the filling and shock-absorbing layer 6 and the two arc-shaped reserved grooves 7 are wrapped with the cable sheath 8. The top and bottom of the cable sheath 8 are provided with horizontal cuts 9, and the cable sheath 8 can be spirally stacked through the horizontal cuts 9. The flexible dual microphone cable also includes a magnetic block 10. Several magnetic blocks 10 are equidistantly installed inside the cable sheath 8 located in the upper and lower arc-shaped reserved grooves 7. The magnetic blocks 10 are located in the upper and lower horizontal cuts 9 respectively. When the cable is spirally stacked, the internal magnetic blocks 10 attract each other to organize the cable bundle.

[0012] The working principle of this utility model is as follows: the double shielding of the copper wire braided shielding layer 3 and the aluminum film shielding layer 5 prevents damage to the sound quality. At the same time, the heat insulation layer 4 enables the wire to work in a low-temperature environment. The horizontal cuts 9 at the upper and lower ends of the cable sheath 8 make the wire bundle more stable when it is spirally stacked. Furthermore, the internal magnetic blocks 10 attract each other to strengthen and fix the wire bundle, preventing it from tangling.

[0013] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary in all respects, and thus equivalent variations within the scope of this invention are included within its scope.
