Ear Trumpets (Ear Horns)

Small London Dome Ear Trumpet (Ear Horn)

This is the second smallest London Dome Ear trumpet in the collection. Overall, it is only 2⅝" in height. The dome itself if only 2⅛" high, while the bell opening is 1¾". It is made of brass painted black (most of the black has worn off) and has a hard rubber “gutta percha” ear tip.

This style of trumpet was named because of its similarity in shape to the dome on St. Paul’s Cathedral in London, England.

The design is a parabolic reflector into an ear tube which achieves considerable gain while maintaining a small size.

Compared to the long ear trumpets which sound more bassy, this tiny ear trumpet sounds more tinny.

The manufacturer is unknown. This London Dome probably dates to somewhere around 1900.
