ABSTRACT:
An acoustical reflector (10) formed by a pair of assembled panels (17, 18), each of which including one or more mouths (45) spaced from one another in ring-like fashion about a centrally disposed opening (27) for the reflector (10), the panels (17, 18) rotatably adjustable independently of one another. Each pair of mouths (45) between the panels (17, 18) cooperate to provide a channel (47) through the panels (17, 18) in the adjustability of the panels. Channel (47) is variable in its capacity for transmitting sound through the reflector (10) and for reflecting sound by utilizing the reflecting surface of one of the outer panel faces (either 21 or 22) with a portion of a facing surface (either 23 or 24) of the alternate panel to reflect back the sound to its source or instrument player's ear(s) for a determination of tonal blend, accurate pitch, or volume balance. A grommet 33 is mounted in the centrally disposed openings (27) of the reflector (10) and about which the panels (17, 18) rotate or orient to one another to adjust the enlarging or reducing of the variable capacity of the channel (47) formed by the adjusted mouths (45). A spacer ring (40) on grommet (33) prevents the panels (17, 18) from scratching one another and projections (43) secured on a panel (17) eliminates wobbling, rotation, and scratching of the panels.
