Paraboloidal percussion instrument

摘要

A percussion instrument, in the simplest case in the form of a djembe, having one or more interconnected resonators in the form of elliptical paraboloids, which meet at their focal points. At or near this common focal point, sound-receiving or sound-emitting devices may be additionally placed. An expedient embodiment provides that the resonators are of a form in which they can be dismantled. A possible method for producing a suitable form is provided by making rings out of plate material.
