This work repurposes the diaphragm of a loudspeaker as a drumhead. The loudspeaker is used as both an input and an output device at the same time, similar to a head of an actual drum. Whereas one may directly hit the loudspeakers diaphragm, we mount it protected as bottom head of a standard tom-tom to prevent the drummer from damaging it. In this configuration, audio effects can be applied to the tom-tom sound, but the sound of the drum still remains natural with its full dynamic range. In particular, we look at filtering effects that can for instance dampen or lengthen the drums decay and at ring modulation to introduce new components to the drums sound.
