Patent attributes
A compound resonance driver or CRD may be used to enhance the tonal qualities of a bass drum system or other sound system. A CRD may comprise a flex ring having two hinge pieces. The flex ring may further comprise a plurality of magnets and the flex ring may be easily folded and placed in a drum and then unfolded. A fixed circular component with a complementary magnet orientation may secure the flex ring. The fixed circular component may be attached to outwardly facing components that resonate or otherwise improve upon the sound of a drum or any sound producing, or sound shaping device or instrument, encompassing properties of an acoustic enclosure. The mass and shape of the CRD may increase the excursion of a drumhead. This longer excursion produces a more natural low frequency waveform.
