The material used for the speaker wire and the corresponding use are as follows: The silk thread consists of a copper conductor (silver) and a center fiber.
1. Copper conductor:
1. Pure copper. Insufficient strength, only for low power speakers;
2. Oxygen-free copper (also pure copper). Poor strength, only used for low-power speakers;
3. Tin-copper alloy. Conductivity is lower than pure copper, medium strength, suitable for mid-range speakers;
4. Cadmium copper alloy. Good conductivity, high strength, suitable for high-power speakers;
5. Silver-plated cadmium copper. Good electrical conductivity, easy to weld, beautiful appearance;
6. Pure silver wire. Excellent electrical conductivity, beautiful appearance, good strength, but expensive.
2. Center fiber
1. Cotton thread. Heat resistance 90 degrees. Strength is general;
2.NOMEX. High strength and heat resistance of 180 degrees;
3. High-moisture modulus viscose staple fiber, heat-resistant 80 degrees;
4. Nylon 3. Surface treatment: anti-oxidation treatment. The feel is related to the weaving method.
There are two main types of common: Weaving wire strands There are many different types of subdivision.
1. One (non-conductive) fiber in the center, surrounded by round copper wire
2. One (non-conductive) fiber in the center, wrapped around copper foil (one or two), and then stranded or woven with this strand. The softest is single stranded strand.
Common lead wires for speakers: Surface treatment WAX treatment can stick the single wires together, so that the overall movement of the silk thread can play the role of enhancement, easy setting, noise removal, no sparking, anti-oxidation, easy welding, no welding, etc. .
Weaving and sturdy structure, the single wires support each other, so the wire is hard, suitable for the speaker with a long distance between the terminal plate and the paper cone and high power.
Stranded wires are generally soft and easy to suppress.
Straight stranded wire is a direct combination of single wire, such as HG4KNHJ, HG7KNHJ. The straight stranded wire is soft, not suitable for long distance use, only suitable for small power speakers.
The twisted pair is the first 4 strands to the left, and then the 3 strands are twisted to the right. For example, HG3X4KNHJ and HG4X4KNHJ have mutual support when they are twisted in the left and right directions. They have a certain hardness and are suitable for medium range power of neutral distance. Speaker use.
2C straight stranded wire 2C, 3C straight stranded wire is a single wire core wire thicker, high strength, and then wrapped with 2 or 3 layers of alloy copper foil, copper foil layer pressure, mutual protection. Has a strong resistance to flexing, for high-power and subwoofer and speakers with large amplitude.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
