摘要 My inventions are: three concentric baffles, plus one non-resonant tailpiece assembly. FIG. (3) Bottom deflecting baffle. drawing sheets, -1,2,AND 3 FIG. (4) Middle detoning baffle, '' '' '' '' '' ''FIG. (5) Top detoning baffle, '' '' '' '' '' ''FIG. (1) Non-resonant tailpiece assembly. drawing sheet, No.3 All three baffles are joined together, as one whole, designed to deflect, and project sound; guiding the path of, sound in a (360) degree radius, VI-A the banjo head, FIG.(6) to the tone ring, FIG. (8) thus, having a clarity a volume sound, and a clarity of tone, continue on, by-passing, the outer edge of the baffles plane surface, spreading out striking the resonator, FIG. (13) bounces back, then exhausts out through, the (22) holes of the flange plate, FIG. (14). Illustration, FIG. (16) drawing sheet number, (4). Please note: all moment of sound, and charity of tone, described in the above paragraph, occurs in sequence, moving, at the rated speed of sound. synopsis when using my inventions, the clarity of tone, (30) percent, and the volume of sound, (8) points, on the decibel meter.
