Speaker cable
The speaker cable is used to connect the power amplifier and the speaker. The current signal flowing in it is much larger than the aforementioned video cable and audio cable. Because of the large signal amplitude, this kind of cable often has no shielding layer. For this kind of cable, the key is to reduce The resistance, because the output impedance of modern power amplifiers is very low, so the requirements for the speaker wire will also increase, such as the use of large cross-sectional area or multi-stranded wire.
Introduction to Sounder
In audio equipment, the wire used for the connection between the power amplifier and the speaker. Since the speaker cable transmits a power signal, there should not be too much signal loss on it. This objectively requires the speaker cable to have extremely excellent electrical conductivity. , Excellent electrical conductivity requires the wire to have extreme transmission capability. The main technical indicators currently used to measure these two points are the N value and the number of wire strands. The N value is a parameter that reflects the purity of the metal used in the production of the speaker wire. Generally, OFC oxygen-free copper and tinned copper +/- are easy to distinguish. Mainly used in various types of speakers, PA projects, home theater connections, public space broadcasting systems.
Audio wire function
Connect each part of the audio to transmit audio and video signals. This is the role of the audio cable. Many people think that the audio cable is just an accessory in the audio, there is no need to be so particular, just find a few pieces. Of course, this sound can also produce sound and picture, but in fact the effect has been compromised. Because, whether it is the audio signal transmission process from the disc player to the power amplifier to the speaker, or the video signal transmission process from the disc player to the TV to the projector, it has been affected by the poor transmission performance of the cable itself. The influence of external electromagnetic interference, weakening and pollution of these influences, weakening and pollution of these influences, so that the sound can not emit high-fidelity sound, TV and projector can not reproduce the lifelike. Therefore, friends who are using and going to use audio systems must know more about audio cables, make reasonable investments in them, and use them correctly, so as to ensure the best audio performance.

The speaker cable is used to connect the power amplifier and the speaker. The current signal flowing in it is much larger than the aforementioned video cable and audio cable. Because of the large signal amplitude, this kind of cable often has no shielding layer. For this kind of cable, the key is to reduce The resistance, because the output impedance of modern power amplifiers is very low, so the requirements for the speaker wire will also increase, such as the use of large cross-sectional area or multi-stranded wire. The wires range from pure copper to silver wires. One of the more expensive speaker cables is dedicated oxygen-free copper speaker cables. Its main characteristics are good electrical conductivity and low resistivity. When it is used, the tone will not increase when the sound is reproduced. few. According to the classification of home speakers, it is divided into home theater speakers (usually 6) and HIFI music speakers (two), which are generally called fever boxes.
HIFI speakers are used to restore the recording sound field with high fidelity, so there must be sufficient protection for the lossless transmission of audio signals. Generally, transmission lines have different impedances to signals of different frequencies. This characteristic is manifested in poor sound quality in terms of sound restoration. For this reason, people have produced a high-end speaker cable called smart signal cable. The characteristics of this line are The signal is divided into two channels according to the frequency. The outer line of a certain thickness passes through the signal above 5KHZ, and the signal below 5KHZ is transmitted through the inner layer of the line. This greatly improves the frequency characteristics of the transmission line and makes the sound reproduced. The effect is good. However, the price is also very expensive. Most of the audio cable brands mentioned above also produce fever speaker cables.
