What interface is mic?

mic is the microphone interface. Mic is abbreviated from Microphone, which means "microphone" in Chinese, and its scientific name is microphone; a microphone is an energy conversion device that converts sound signals into electrical signals. There are three common microphone interfaces: 1. 6.35mm large two-core TS, which is mainly used for mono signal transmission. It has poor anti-shielding effect and has little impact from short wires. The connected cable is a single-core plus shielded wire; 2. Large The three-core TRS connector is connected to a balanced line and has a three-section head. It has good electrical performance, strong anti-interference performance and higher reliability; 3. XLR interface.

mic is the microphone interface.

mic is the abbreviation of Microphone, which means "microphone" in Chinese. Its scientific name is microphone, also known as microphone and microphone. A microphone is an energy conversion device that converts sound signals into electrical signals.

mic is used to convert sound signals into electrical signals, such as WeChat voice, WeChat video, QQ voice, QQ video, and phone calls, all of which require a microphone.

If there is no microphone, your voice will not be heard by the other party.

The corresponding counterparty will have a receiver, which converts electrical signals into sound signals. In this way, your voice is sent successfully.

Common microphone interface

There are three common microphone interfaces, namely 6.35mm sophomore Core TS, 6.35mm triple core TRS, XLR.

Big 2-pin TS connector

The 2-pin TS connector is similar in shape to the 3-pin TS connector, but has one less ring than the 3-pin TS connector. It is mainly used for mono signals. Transmission, anti-shielding effect is poor, and short-term effects are not significant. The connected cable is a single-core plus shielded wire. It can be realized by core-to-core, shield-to-shield welding and RCA, BNC and other mono-channel connectors. Convert.

Features: The large two-core connector can only transmit unbalanced signals, so the main application scenario is for guitars, basses and other musical instruments to be connected to mixers or sound cards.

Big three-core TRS connector

The big three-core TRS connector is connected to a balanced line, which is mostly used in professional equipment. The head is three-section, with good electrical performance and resistance to It has strong interference performance and higher reliability.

Features: The big three-core can be used for mono balanced connection, such as the microphone to the LINE input port of the mixer, or it can be used for single-jack stereo connection. Such as the headphone jack.

XLR connector

The XLR connector is a more professional audio interface head compared to the above two, and can be used for high-end microphones such as condenser microphones. The electrical performance and anti-interference performance are very strong, and the reliability is also extremely high. XLR connectors are divided into two-core, three-core, and four-core types, but the most common ones are three-core XLR connectors. The three-core XLR connector is divided into ground terminal, hot wire, and cold wire, which correspond to the corresponding positions of the microphone.

Features: The XLR head is specially designed to serve condenser microphones. It must use 48v phantom power or a microphone preamp to input sound to the computer normally. At the same time, because the XLR head can be powered by a mixer, the microphone does not need a separate power supply. Compared with other microphones, there is less chance of failure due to battery shortcomings, and the reliability is higher.

Expand knowledge:

Common commercial microphone types include condenser microphones, crystal microphones, carbon microphones and dynamic microphones. Commonly used condenser microphones use two energy sources: DC bias power supply and electret film. Both condenser microphones and crystal microphones convert sound energy into electrical energy, producing a changing electric field. Carbon microphones use a DC voltage source to change their resistance through sound vibrations, thereby converting acoustic signals into electrical signals.
