Audio cables are used to transmit sound signals between audio devices. They are mainly used to connect audio sources (such as mobile phones, computers, players, etc.) to audio equipment, such as headphones, to ensure high-fidelity transmission of audio signals.
Core functions and features of audio cables
Signal transmission.
Audio cables transmit analog or digital audio signals, such as music and conversations, through physical connections to avoid interference or delay problems in wireless transmission. 2
Common application scenarios: connecting mobile phones to car AUX interfaces, computers to speakers, players to amplifiers, etc.
Key factors affecting sound quality.
High-quality audio cables can reduce signal loss and retain sound details (such as bass depth and treble clarity). Poor-quality cables may cause noise or distortion.
Type and interface diversity.
3.5mm audio cable: universal, used for mobile phones, headphones and other devices. 2
RCA lotus head cable: used for DVD and audio systems, supporting left and right channel separation. 4
Professional speaker cable: Different from ordinary audio cables, it is designed for high-power audio (such as home theater).
Length and adaptability. The standard length ranges from 1.5 meters to 10 meters. It needs to be selected according to the distance of the device. Too long may cause signal attenuation.
