Description

for the Federal Republic of Germany, Italy and Switzerland:

Reconstruction and modification of accordion and harmonica keyboards using alkantara (buffers) and goatskin or other types of leather.

For professional musicians there is the problem of touching down hard

the keys of a keyboard, which particularly disturbs the microphone work,

In order to make the keyboards almost noiseless, the above have worked out a change in all keys.

Then flap linings, as the following drawings show, no longer glued directly to the carrier plates or wooden flaps, but attached to alkantara buffers.

So far, when the button is released, the flaps hit the resonance box directly (called: filling)

The resonance box is covered with goat leather or suede so that that the buffer flaps put on this leather frame.

This lowers the phon number of the surcharge so that one only 1/3 of the volume when idling? perceives while at Playing, i.e. with sound, nothing can be heard from putting it on.

With this construction, one of the greatest problems of hand-drawn instrument construction is solved.

Until now:
