ABSTRACT:
A multi-function microphone connecter includes a main body having a cylindrical member and a dust cover unit combined with a front end of the cylindrical member. The cylindrical member has a large center plug hole for a microphone plug to insert, and small plug holes for another microphone plug to insert. The dust cover unit consists of a rotatble member, a silicon rubber member and an outer cover member. After the dust cover unit are combined with the main body, the rotatable member may be rotated to close up the small plug holes, preventing dust from drifting therein, always keeping normal function. Further, the silicon rubber member has fan-shaped sections able to be pushed to bend inward by the first microphone plug. The fan-shaped sections can close up the large plug hole to prevent dust from moving therein when the second microphone plug is used.
