Understanding 3.5mm audio cables: structure, types (TRS/TRRS) and applications

3.5mm audio cable is a common cable for connecting audio devices. Its structure seems simple, but it contains multiple important components that work together to ensure the transmission quality of audio signals. Therefore, it is crucial to understand the structure of 3.5mm audio cable.

What is 3.5mm audio cable?

3.5mm audio cable (also known as AUX cable) is a common analog audio cable with a standard plug diameter of 3.5mm (about 1/8 inch) and is usually divided into three sections (TRS: left channel, right channel, ground) or four sections (TRRS: left, right, microphone, ground) of metal contacts. It is widely used to connect smartphones, computers, portable players, headphones, speakers, car audio and other devices to achieve stereo audio signal transmission. It has become one of the most common audio interfaces in the consumer electronics field because of its small size, popularity and strong compatibility.

3.5mm audio cable type: TRS, TRRS

TRS (also known as "stereo mini") is the most common 3.5 mm connector. The tip of the TRS plug is for the left channel signal, the ring is for the right channel signal, and the sleeve is for the ground wire.

TRRS connector is suitable for headphones or earbuds with inline controls and built-in microphones. The tip is for the left channel, the first ring is for the right channel. The second ring is for ground, and the sleeve is for the microphone channel.

Application scenarios: diverse and extensive

The 3.5mm audio cable is a common audio connection cable with a wide range of application scenarios, mainly including the following aspects:

1. Connecting audio devices: Mainly used to connect audio source devices such as mobile phones and MP3 players to playback devices such as speakers and car stereos. Simply plug the two ends of the cable into the output port of the device and the input port of the receiving device to play music, podcasts or listen to books.
2. Auxiliary input/output:Many electronic devices are equipped with dedicated auxiliary (aux) input or output ports, usually represented by a small headphone icon. The 3.5mm AUX cable is used to establish a wired connection between these devices to transmit audio signals, such as connecting a mobile phone to a car stereo to play music.
3. Recording and mixing: In professional recording and mixing equipment, 3.5mm stereo auxiliary cables also play an important role. These cables are used to connect various audio devices, such as microphones, musical instruments, audio interfaces, and studio monitor speakers. They help transmit audio signals between different components, allowing accurate recording, monitoring, and mixing of audio tracks.

It should be noted that although the application scenarios of 3.5mm audio cables are very wide, when selecting and using them, factors such as cable quality, length, and shielding performance need to be considered to ensure the transmission quality and stability of audio signals.
