Sound cable, also known as loudspeaker cable, is mainly used to connect power amplifier, main speaker and surround speaker in home theater, that is, to connect power amplifier and speaker. Shandong audio manufacturer reminds you that compared with video cable and audio cable, its current signal is relatively large. Because of the large signal amplitude, the audio cable often has no shielding layer.
For this kind of wire, the key is to reduce its resistance. Because the output resistance of modern power amplifiers is very low, the requirements for speaker wires are also increased, such as using large sectional area or stranded wires. How to distinguish audio cable from audio cable?
1. Audio cable, audio cable and wire
The audio cable directly passes through the power signal. Because of the large current passing through, the copper core of the cable is usually relatively thick. In order to ensure the high frequency passing through and reduce the resistance attenuation, most of the audio cables are silver, gold or oxygen free copper wires. Audio cable generally includes copper plated audio cable and oxygen free copper audio cable.
Audio cable is used to transmit electroacoustic signals or data. The signal passing through small current and small power has high impedance and is easy to be interfered. Therefore, it is generally shielded wire, and the wire diameter is generally thin. The types of audio cables can be divided into two categories: audio electrical signal cable "and" audio optical signal cable ". The audio electrical signal cable is commonly used in the market. The general specifications are: 3.5mm male to male audio extension cable, 3.5mm male to female audio extension cable, dual lotus head audio cable, etc.
2. Difference between audio cable and audio cable
Sound cable mainly transmits power signal, so speaker cable is required to have good conductivity and high-quality transmission capacity. At present, the oxygen free copper sound wire, also known as the gold and silver wire, is relatively mainstream and has low resistance. Audio gold and silver wire usually has no shielding layer, because the current signal flowing in it is larger than audio wire and video wire, and the signal amplitude is large. It is important to reduce the resistance of the line. The impedance when the power amplifier is lost is very low.
The audio cable passes through the signal of small power and small current, and has high impedance and is easy to be interfered. Therefore, it is generally shielded wire with thin wire. Audio cable usually has a shielding layer, but audio cable often has no shielding layer. The key is to reduce the resistance. Among the dark blue avenue audio lines, the more expensive one is the special line for oxygen free copper speakers, which is mainly characterized by good conductivity and low resistivity.
