The audio "wire" is not only a seemingly simple conductor structure, but also a complex system. "Wire" is by no means an accessory to the sound system, but an important component! Therefore, a good "wire" must have a good internal structure, different structures show different effects, and its resistance, capacitance and inductance will be completely different. “YL†shares the most common structure of “wire†(“power cordâ€, “horn cableâ€, “signal lineâ€).
First, the "power cord" in the production structure conductor core can be designed as: 7 strands, 19 strands, the middle of 7 strands plus three braided conductors, so that there is enough density to reduce the resistance, capacitance and inductance A quantity, thus outputting sufficient current.
Second, the "trumpet line" structure can be divided into two types: one, the core is a single conductor for the twisted pair. Second, the core is a single conductor and a pair of aluminum plating shields are applied in a twisted manner. Both of these configurations have sufficient density to reduce the resistance, capacitance, and inductance, thus outputting sufficient horn current.
Third, the "signal line" structure: the car signal "signal line" is weak due to the transmitted electronic signal, and the transmission distance is long (about 5M). What is more unfavorable is that the electric field magnetic interference is quite serious, so the signal line of special structure must be used. competent. However, there are three most common "signal line" structures:
A: It is simple to use the double-strand copper wire as the center conductor to cover the insulating material. However, the production process must be a density of 8MM-10MM, which will also result in the line-to-line. Shielding effect.
B: The single-strand copper wire is used as the center conductor with the insulating material, and the shielding layer is covered with aluminum, and then the conductor copper wire is woven with a braid of 99% density. This process is also called double-layer shielding.
C: The double-strand copper wire is used as the center conductor to cover the insulating material, the single-stranded copper wire is used as the negative electrode and the grounding wire shield, the outer layer is covered with the shielding aluminum berth layer, and then the conductor copper wire is woven with the 100% density braid layer. This practice is not only independent shielding but also enhances resistance to dryness. (This design is directional connection, the installation should pay attention to the connection direction between the host and the amplifier)
