Telescoping Ear Trumpet
The popularity of the Townsend Telescoping Ear trumpet can be attributed to the fact that it was compact, and easy to conceal. Interestingly, as far back as the early 15th century there is record of a slide trumpet, which uses the same basic principle (pictured right.) Needless to say this is an example of the obvious, using the existing ear trumpet technology with telescoping technology to solve the problem of size.
