Globe Auditube Conversation Tube
The Globe Auditube was a conversation tube manufactured by the Globe
Phone Manufacturing Company
of Boston, MA around
1912.
This conversation tube is 45 inches long. It was apparently produced in three sizes, priced $5.00, $5.50 and
$6.00 for the small, medium and large sizes. (The one shown here is likely the
large one, but can't be sure.)

Auditube apart from other conversation tubes is that it used a diaphragm ear piece which provided a high frequency boost
to the listener. This diaphragm ear piece was similar to that employed on
the Otophones made by E.B. Meyrowitz around 1887. |
