The present invention provides a microphone assembly having shielding function for a motor vehicle, comprising: a microphone circuit board having a microphone, which is supplied by a differential audio bus such that the ground potential of the microphone is floating; a cover which is located outside the microphone circuit board; a foamy part which is located between the cover and the microphone circuit board; and a shielding film which is suitable for shielding the microphone against electrostatic discharge, wherein the shielding film is located between the cover and the foamy part and covers the outer surface of the foamy part, and wherein the shielding film is electrically conductive and grounded to a vehicle chassis ground potential. In this situation, the shielding film can collect electrostatic charges and guide them to the chassis ground of the vehicle, so that electronic components on the microphone circuit board under the shielding film, especially the microphones having the floating ground, can be shielded from electrostatic discharge (ESD) damage. As a result, the ESD robust performance of the microphone assembly is significantly improved.

This application discloses a microphone that includes a handle portion, a control portion, and a microphone head that are connected in sequence. The control portion includes a first circuit board and multiple light-emitting assemblies arranged along a perimeter of the control portion. The first circuit board is electrically connected to the multiple light-emitting assemblies for controlling the multiple light-emitting assemblies to emit light in a preset light-emitting mode. In the solution of this application, multiple light-emitting assemblies are arranged in the control portion, so that when in use, the color of the light and the brightness of the light-emitting assembly can be automatically changed according to the microphone song or through a control button, so that the multiple light-emitting assemblies of the microphone can illuminate in a preset manner.
