The present invention provides a microphone support which includes a restriction groove 520 between a universal ball 50 and a mounting member 70 in order to restrict the rotating angle range of the universal ball 50 rotating with the axis line of a pipe through-hole 510 centered, so that the direction axis L of a microphone is restricted to have a designated swinging angle range with the talker side of the microphone centered. Therefore, no breaking wire by wire-twists is generated, and since the microphone is prevented from facing to loudspeakers owing to careless handling, no howling is also generated.
