What's the difference between audio cable and ordinary cable?

The difference between audio cable and ordinary cable is as follows:

Audio line, usually used for line input and line output.

It is a low-current and low-power signal with high impedance, so it is generally a shielded wire, but the wire is generally thin.

Speaker cable, which is used to connect the final stage of the power amplifier with the speaker and directly transmit the power signal, is usually thick because of the large current. Moreover, in order to ensure high frequency pass and reduce resistance attenuation, most of them are silver-plated and gold-plated copper or copper-silver alloy wires.

Wire refers to the wire that transmits electric energy. Divided into bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires and various profiles. Mainly used for outdoor overhead and indoor buses and switch boxes. Electromagnetic wire is an insulated wire that generates a magnetic field or induces a current in the magnetic field after being electrified. It is mainly used for windings of related electromagnetic equipment such as motors and transformers.
