Description

Technical Field

[0001] The utility model relates to the field of microphones, in particular to a multifunctional microphone. Background Art

[0002] The most popular and most widely used controller on the market is Microsoft's XBOX game controller, but this controller has no built-in microphone. If users want to transmit the audio channel to the game, they need to purchase the expensive and bulky Bluetooth headset optional for XBOX, which is unacceptable for users with limited budgets and who pursue simplicity. Alternatively, they can use a HEADSET four-stage headphone cable with a built-in microphone to connect the audio channel to the controller. However, the sound recorded in this way is small and noisy, and there is no way to mute the microphone with one click, nor can the sound of the microphone be monitored in real time. The sound quality of the headset is poor, and it also affects the battery life of the controller, which is very unfriendly to gamers. Summary of the Invention
