Many people always confuse audio cables with speaker cables, and don't know the difference between the two. So what is the difference between audio cables and speaker cables?
1. What is an audio cable
Audio cables are used to transmit electro-acoustic signals or data. Signals with low current and low power have high impedance and are susceptible to interference. Therefore, they are generally shielded cables, and their wire diameters are generally relatively thin.
2. What is a speaker cable
The speaker wire is also called the "gold and silver wire" in the industry. It is mainly used to connect the power amplifier and the main speakers and surround speakers in the home theater.
During the transmission process of the speaker cable, the current signal flowing inside is larger than the audio cable, and the signal amplitude is relatively large. The impedance of the power amplifier should be very low when outputting. The resistance of the cable should be low, and the resistance of the shielding layer will become larger, so the speaker The line is not shielded.
3. The difference between audio cable and speaker cable
The types of audio cables can be divided into two categories, "audio electrical signal cables" and "audio optical signal cables. Audio electrical signal cables are commonly used in the market. The general specifications are: 3.5mm male-to-male audio extension cables, 3.5mm male to female audio extension cable, double lotus head audio cable, etc.
Speaker cables are generally divided into single-skinned speaker cables and double-skinned speaker cables. Single-skinned means that there is only one outer skin wrapped around the copper core, while double-skinned means that there are two layers of outer skin wrapped around the copper core (the outer layer is thicker). , The inner layer is thinner).
The single-layer skin is generally a transparent skin, and the two-strand copper core is made of oxygen-free copper on one side and tinned copper on the other. Generally, oxygen-free copper is the positive electrode, and tin-plated copper is the negative electrode. The color of the double skin is red, both sides are brass-colored, and the oxygen-free copper core is marked with a red line on the positive side.
The audio signal cable can be used to connect the music output signal equipment of mobile phones, CD players, and MP3 to the connection line between the power amplifier. Speaker cables are mainly used in various types of speakers, PA projects, home theater connections, and public space broadcasting systems.
