发明名称 Muffler for bass drums
摘要 A muffling device for enhancing the sound and feel of a bass drum. The muffling device includes a flat pad and a pillow which is hinged to the pad and which exerts spring resistance to flexure about the hinge. The underside of the pad has a pair of fastening strips for application to mating fastening strips on the drum body to secure the pad in the drum body with the pillow flexed about its hinge and resting against the batter head of the drum to apply a tension force to it. The pad and pillow have sound absorbing cores continued within netting having mesh openings through which the cores are exposed.
