Abstract: An acoustical grille (1) secured to a top of a receiver (50) of microphone (5) with an annular ring (10) free from spit moisture installed to a rim of the acoustical grille (1) with grille shells (11) shielded over the receiver (50); at least, a stand (2) connected between the annular ring (10) and positioning ring (3), whereby a distance kept between the grille shells (11) and the receiver (50). Grille shell (11) not only prevents spit in but low pitch, mid pitch, and high pitch sounds can be superimposed received into the receiver (50). Confused or harsh sound emissions of users or breath sounds can be absorbed between the grille shells (10), thereby sounds picked up by the microphone demands for a higher pitch, where the original sounds can be tuned within higher vocal compass. It may be played at soft volume; the sounds are mellow and expressive.
