Meyrowitz Otophone 1B
Otophones were manufactured by E. B. Meyrowitz in New York, an
optician who also manufactured surgical instruments. Otophones were
manufactured starting about 1887. They consist of a cone opening with
a diaphragm ear piece set at right angles. They are held flat against
the ear with the cone facing forward. Because of the diaphragm ear
piece, they offer considerable gain in the high frequencies. The 1B
model is the smaller of two sizes with a cone opening of 2.5” and a 2"
diaphragm in the ear piece. |
