Ear Trumpets (Ear Horns)

Audiscope (Regular) Ear Trumpet (Ear Horn)

The Audiscope (Regular) was manufactured by the American Earphone Co. Inc. of  New York, NY around 1925, It is a two-section telescoping ear trumpet made of hard rubber.

The bell is cut at an angle giving it a slightly-scooped appearance. The purpose of the scoop according to one catalogue is "so that conversations may be carried on from the side. It is for this reason considered more convenient."

The Audiscope is easy to identify, unlike many of the early ear trumpets. On the back at the bell end it gives its name—Audiscope—and manufacturer—American Earphone Co. of New York.

The Audisocpe had two rather unusual features. First, it was flattened on the back rather than round like most ear trumpets. This gave less of a bulge when carried in a pocket.

Second, it had a clip at the mouth of the bell to hold the second section so it didn't rattle around. This is the only multi-section ear trumpet I've seen with such a clip.

The angled ear-piece screwed on to the narrow end of the second section. This made manufacturing the straight second second section easier.
