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.

What are the internal interfaces of a computer motherboard? Recommended introduction to the internal interfaces of a computer motherboard
Mar 12, 2024 pm 04:34 PM
When we assemble the computer, although the installation process is simple, we often encounter problems in the wiring. Often, users mistakenly plug the power supply line of the CPU radiator into the SYS_FAN. Although the fan can rotate, it may not work when the computer is turned on. There will be an F1 error "CPUFanError", which also causes the CPU cooler to be unable to adjust the speed intelligently. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard. Popular science on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard 1. CPU_FANCPU_FAN is a dedicated interface for the CPU radiator and works at 12V

Solution to NotImplementedError()
Mar 01, 2024 pm 03:10 PM
The reason for the error is in python. The reason why NotImplementedError() is thrown in Tornado may be because an abstract method or interface is not implemented. These methods or interfaces are declared in the parent class but not implemented in the child class. Subclasses need to implement these methods or interfaces to work properly. How to solve this problem is to implement the abstract method or interface declared by the parent class in the child class. If you are using a class to inherit from another class and you see this error, you should implement all the abstract methods declared in the parent class in the child class. If you are using an interface and you see this error, you should implement all methods declared in the interface in the class that implements the interface. If you are not sure which
Application of interfaces and abstract classes in design patterns in Java
May 01, 2024 pm 06:33 PM
Interfaces and abstract classes are used in design patterns for decoupling and extensibility. Interfaces define method signatures, abstract classes provide partial implementation, and subclasses must implement unimplemented methods. In the strategy pattern, the interface is used to define the algorithm, and the abstract class or concrete class provides the implementation, allowing dynamic switching of algorithms. In the observer pattern, interfaces are used to define observer behavior, and abstract or concrete classes are used to subscribe and publish notifications. In the adapter pattern, interfaces are used to adapt existing classes. Abstract classes or concrete classes can implement compatible interfaces, allowing interaction with original code.

Inner class implementation of interfaces and abstract classes in Java
Apr 30, 2024 pm 02:03 PM
Java allows inner classes to be defined within interfaces and abstract classes, providing flexibility for code reuse and modularization. Inner classes in interfaces can implement specific functions, while inner classes in abstract classes can define general functions, and subclasses provide concrete implementations.
Java interfaces and abstract classes: revealing the inner connection between them
Mar 04, 2024 am 09:34 AM
Interface Interface defines abstract methods and constants in Java. The methods in the interface are not implemented, but are provided by the class that implements the interface. The interface defines a contract that requires the implementation class to provide specified method implementations. Declare the interface: publicinterfaceExampleInterface{voiddoSomething();intgetSomething();} Abstract class An abstract class is a class that cannot be instantiated. It contains a mixture of abstract and non-abstract methods. Similar to interfaces, abstract methods in abstract classes are implemented by subclasses. However, abstract classes can also contain concrete methods, which provide default implementations. Declare abstract class: publicabstractcl
