    I’m looking for more online photos of the inside of a vibrandoneon.
    On this page, there is also 1 inside photo

    Vibrandoneon-Inneres (vibrandoneon inside)

    The bottom is transparant acryl glass , so you can have a look at the reeds.

    Are there more online pics and info on the making of these vibrandoneons?

    Stephen, later this evening I will open up my Vibrandoneon and take some pictures then post, there are a couple of different models, so I will post open and closed.

    Thank you very much for those online photos of your vibrandoneon !
    They are a great help for all amateurs and professional free reed instrument makers , to understand the functions and construction of melodica and accordina types !

    I’m especially interested in the 2 seperate “air / wind chambers” that seem to be perfectly airtight, and the mouthpiece airflow going in 2 seperate “air / wind chambers”. I read online this system works great in the vibrandoneon, the reeds respond very quickly. Fascinating.
    Thank’s again, I hope more vibrandoneon and top quality melodica owners can post photos of detailed construction. We can learn from those pics.

    The reason I hope to see detailed photos of the direction the airflow is going into the “wind chests” , is to get a better understanding of how the air should “touch” the tips of the reeds, and set the reeds to vibrate.

    I have seen different melodica types and accordinas. Some are held horizontally, some are held vertically by the players. The reed plates or “reed blocks” sometimes are in horizontal position or vertical, and thus the reeds sometimes lay flat or stand up. It’s a difficult topic, but I try go find out the best direction of the airflow (breath economy, reed response, …)

    Scientific articles about free reed acoustics are very scarce, and difficult to understand. Even top experts have done experiments, and some results surprised even the scientists (see eg articles on the patmissin website about acoustics in mouth harmonicas and bending in mouth harps…

    If someone knows the online patent for your vibrandoneon (including the technical drawings) maybe we could learn more.
    I know there is an Italian “vibrandoneon” (?) patent by G. Tonini (?), but I just can’t find it online.
