Homework Help: Analog Steel Plate Sound Synthesizer, cut plate shapes to make oscillators and filter

  1. Aug 12, 2017 #1
    1. The problem statement, all variables and given/known data
    Hello there, I thought a fully analog , cutting vibrational shapes on steel plate and hit to each shape by fingers and produce whichever sine , square , triangle vibration you want and filter of those collections of vibrations by another steel cut shape and make a synthesizer .

    Steel is stainless and 1 mm thick

    everything is cut steel , works like percussion instrument.

    2. Relevant equations
    I dont know how to invent shapes for to cut steel for desired vibrations and filters

    3. The attempt at a solution

    I'd look at reed organs/instruments to get some ideas. A clarinet reed for example, produces a square wave. Filtering a square wave gives a triangle wave. A resonant cavity can filter that to a sine wave.

    I'm not sure these waveforms can be produced with a finger providing the energy, but maybe you meant forming the metal by hand (with the fingers)?
