Conference room microphone is called the meeting microphone and some people call it an omnidirectional microphone. The conference room microphone is a portable conference phone product that not only enables high-quality Internet teleconferencing over the Internet through a computer interface, but also a speakerphone and microphone hands-free calling device for wireless mobile phones through the headphone jack for high quality wireless mobile conference calls. Its style is classic and easy to carry. The microphone pickup direction can be selected according to the conference scene, which is suitable for use in conference rooms and offices.

Most conference room mics on the market today also use electret microphones. The meeting microphone not only collects sound but also outputs sound.

Because the conference room mic has both sound input and output functions, its circuit design must have an anti-echo (self-excitation, howling) circuit. Therefore, the most important reference point for judging the quality of a conference room mic is its ability to resist the echo.
