Abstract

A radio microphone to be incorporated in a cellular phone handfree kit well-suited for using in a vehicle is composed of a main clip, an auxiliary clip a rotatable base, and a microphone main body, it is an all directionally turnable and handy communication device made up with low cost.

Claims

1. All directionally turnable radio microphone comprising:

a main clip having a containment hole with two opposing trap slots stretched radially out of its circumferential fringe;

a rotatable base with a rotating shaft attached to its center portion and having two elastic straps erected vertically at its both ends thereof and the inner surfaces of both said elastic straps being formed into male protrusions each provided with several notches equidistantly disposed around its circumference, and the front end of said rotating shaft being provided with two radially emerged stoppers; and

a microphone main body having a female recess formed at each of its both sides thereof each recess being provided with two inwardly emerged protuberances;

with this construction, said rotating shaft of said rotatable base is inserted into said containment hole of said main clip with said two stoppers trapped in said two trap slots such that said rotating shaft is able to rotate said rotatable base by 360°

on said main clip, on the other hand, said microphone main body is conjoined with said rotatable base by said female recesses coupled to said male protrusions such that said main body is secured to said rotational base by the resilient force provided by said two elastic straps of said rotatable base thereby said microphone main body is turnable 180°

up and down about an axis connecting the center of said two male protrusions, during turning, said microphone main body can be halt at a position where said protuberances of said female recesses are mated with certain pair of notches formed on said male protrusions thereby the microphone main body is positioned at a desired direction.

2. The microphone of claim 1, wherein said microphone main body is provided with a control board having a push button switch, a microphone and a LED all equipped thereon.

3. The microphone of claim 1, wherein said microphone body has an auxiliary clip.

4. The microphone of claim 1, wherein a round is formed at the front tip of said stopper of said rotating shaft so as to facilitate insertion of said stopper into said trap slot of said containment hole.
