Telharmonium console by Thaddeus Cahill 1897. The Telharmonium (also known as the Dynamophone [1]) was an early electrical organ, developed by Thaddeus Cahill c. 1896 and patented in 1897. [2] [3] [4] The electrical signal from the Telharmonium was transmitted over wires; it was heard on the receiving end by means of "horn" speakers. [5]

A number of instruments have been invented, designed, and made, that make sound from matter in its liquid state. This class of instruments is called hydraulophones . Hydraulophones use an incompressible fluid, such as water, as the initial sound-producing medium, and they may also use the hydraulic fluid as a user-interface.
The A-20 was designed for churches and small-capacity halls, and featured a set of doors in front of the speaker, that could be closed when the organ was not in use. [96] The D-20 was introduced in 1937 and only allowed sound from the speakers to escape by a louvered opening on one side and a gap in the top. [97]
A tonewheel or tone wheel is a simple electromechanical apparatus used for generating electric musical notes in electromechanical organ instruments such as the Hammond organ and in telephony to generate audible signals such as ringing tone. It was developed by Thaddeus Cahill for the telharmonium c. 1896 and patented in 1897. [1]
