Vibraphones

Vibraphones were devices patented by Charles Fensky about 1923. They were produced until about 1935.

Vibraphones were apparently considered fraudulent although attempts to stop their production and advertising were unsuccessful.

They were manufactured in various sizes (the ones shown above are the large size) and consisted of silver chambers in an “L” shaped design. Inside the larger chamber were small metal reeds that vibrated with the sound. It is doubtful that they would have helped anyone, even with a mild hearing loss.

Vibraphones came in at least 3 sizes—large (R-4), medium (R-2) and small (R-1).

As you can see on the box, these Vibraphones (large size) were made by the European Vibraphone Co. in London.
