[0002] An audio interface is a device that connects a microphone or other sound source to a computer. It serves as a bridge between analog and digital signals. Audio interfaces are usually used in conjunction with front microphones, line inputs, and a series of other input devices. Many electronic products with sound playback effects (computers, mobile phones) are equipped with audio interfaces. Through the audio interface, external speakers or headphones can be electrically connected to the internal circuits of electronic products, so that audio signals can be transmitted from the electronic product body to the speakers or headphones for playback.

[0003] When the audio and video interface is not in use, there is a possibility of foreign objects entering. Failure to remove the foreign objects will affect the complete insertion of the audio and video connector, and further affect the normal use of the connected device. However, since the hole specifications of the audio and video interface are usually small, it is somewhat difficult to remove the foreign objects. Utility Model Content
