ABSTRACT:
A portable apparatus (100) for mechanically amplifying voice and percussive sound includes a flared horn (10) with a horn mouth (26) and voice opening (28) for projecting sound in a desired directional sound radiation pattern. Within an opening formed in the body of the horn, a vibratile membrane (20) is secured by a retaining ring (22). The vibratile membrane (20) is tensioned to produce a drum sound when excited by percussion. Two handles (12) are mounted to the outer surface of the horn to enable lefthanded and righthanded persons to conveniently hold the horn. The horn is of frusto-conical shape and appropriate dimensioning of the horn flare in relation to the width of the horn mouth defines a structure operable to permit the sound waves to cling to the horn inner surface and project outwardly therefrom.
