Brass Oval Telescoping Ear Trumpet (Ear Horn)
This large brass oval-shaped telescoping domed ear trumpet has no
name or manufacturer's marks on it.
Date of manufacture was probably somewhere around
1910.
The dome of this ear trumpet measures 4 15/16" (12.6 cm) high. The
oval end measures 2⅞" (7.3 cm) x 1 15/16" (5.0 cm). The ear tube
collapses and extends. In its fully collapsed position the overall
height measures 5 7/16" (13.8 cm) while in its extended position it
measures 8" (20.3 cm).
This domed ear trumpet weighed 6.1 oz. (172 g), quite heavy for its
size.

One of the cool features of this large brass oval-shaped telescoping
domed ear trumpet is that the ear tube swivels out for use (as shown),
and then swivels over the top of the dome, thus giving it a smaller
profile for storing or carrying it (see bottom picture). The oval
shape also makes fitting it in a pocket easier and less noticeable as
there is less of a bulge than with round domes of a similar size. |

If you wanted to, you could extend the ear tube of this large brass
oval-shaped telescoping domed ear trumpet up to a practical limit of
about 2¾" (7.0 cm) although I'm not sure why you might want to. It fits
comfortably in your hand in its collapsed position. |

telescoping domed ear trumpet. You can see the bottom of the "U" of
the ear tube inside the grill (upper left). The way
these domed ear trumpets worked was that the dome had a parabolic shape
so that the sound waves that entered the base of the dome reflected off
the curved sides of the top of the dome right into the large end of the
ear tube making these ear trumpets surprisingly effective. |

showing the ear tube swung back over the top of the dome for storing or
carrying it. The ear tube was much less likely to get caught on things
in this position.
