Abstract

Il fondo (1) della fisarmonica presenta una generale struttura a sandwich con parti fisse (2a, 2b, 2c) attraversate da file di fori (4a, 4b, 4c) allineati fra loro ed ordinati in gruppi, ad esempio coppie, di fori adiacenti. I fori in ciascun gruppo (9a, 9b, 9c) sono presentanti dimensioni sostanzialmente inferiori alle dimensioni dei fori. L'occlusione dei fori per interdire il passaggio dell'aria attraverso i fori (4a, 4b, 4c) viene realizzata tramite una pluralità di lamine (6a, 6b) scorrevoli che occludono tali fori (4a, 4b, 4c) secondo una generale sequenza alternata.E' così possibile ottenere un addensamento dei fori e delle rispettive voci, aumentando il numero di queste ultime a parità di dimensioni complessive dello strumento.(Figura 3a-b)
