Audio cables are used to transmit electrical sound signals or data. They carry low current and low power signals, have high impedance, and are easily interfered with, so they are generally shielded cables, and the wire diameter is usually quite thin. Audio cables can be divided into two main categories: 'audio electrical signal cables' and 'audio optical signal cables'. The commonly used type in the market is the audio electrical signal cable. Common specifications include: 3.5mm male to male audio extension cable, 3.5mm male to female audio extension cable, and dual RCA audio cables.

RCA, commonly known as the lotus socket, is also called the AV terminal or AV interface. Almost all televisions and DVD players have this interface. RCA usually comes in pairs, with a white audio interface and a yellow video interface. It typically uses RCA (commonly known as the lotus head) for connection, and when in use, you only need to connect the standard AV cable with lotus heads to the corresponding interfaces.
Used for video signage and video surveillance. They connect laptops and desktop computers to home theater systems. They connect some TVs to DVD players, Blu-ray players, game consoles, cameras, and digital cameras. RCA connects audio devices such as power amplifiers, mixers, speakers, CD players, and turntables.
