Description

Double-layer water-blocking anti-interference shielding horn wire

Technical Field

The utility model relates to the field of loudspeaker wires, in particular to a double-layer water-blocking anti-interference shielding loudspeaker wire.

Background

The speaker line is also called as sound line, which is used to connect the power amplifier and the sound box, wherein the current signal flowing through the speaker line is far greater than that of the video line and the audio line.

The patent number CN208014432U discloses an anti-interference loudspeaker line, and the first conductive metal wire shielding net layer is arranged outside the first copper wire to play a role in shielding electromagnetic signals generated by the first copper wire, and the second conductive metal wire shielding net layer is arranged outside the second copper wire to play a role in shielding electromagnetic signals generated by the second copper wire, so that signal interference between the first copper wire and the second copper wire can be effectively avoided. Through setting up the shielding mesh layer of third electrically conductive wire, can further prevent that the loudspeaker line from causing electromagnetic signal to other signal lines to interfere with, also avoid other signal lines to cause the interference to the loudspeaker line. Furthermore, by arranging the carbon fiber material layer and the aluminum foil paper layer, the fireproof and high-temperature-resistant effects can be achieved. Through setting up nylon stratum reticulare, can play the effect of strengthening loudspeaker line intensity. The flame-retardant coating is coated to play a role in flame retardance.

The prior art horn wire has the following disadvantages: 1. in the above patent, the copper wire is shielded only by the copper woven mesh, so that the shielding effect is poor, and the electromagnetic field of the copper wire is still interfered; 2. when the horn wire is used, the horn wire is often pulled and bent, the elasticity of the horn wire is poor, the horn wire is easy to break and damage after being bent for many times, and the use is inconvenient; for this purpose, we propose an anti-interference shielded horn wire. Therefore, it is necessary to invent a double-layer water-blocking anti-interference shielding horn wire to solve the above problems.
