Nikola Tesla reportedly created a analogous device in 1881, but was not issued a patent. During this time, Thomas Edison was issued a British patent for a system using compressed appearance as an amplifying mechanism for his early cylinder phonographs, IPOD Speakers but he ultimately settled for the familiar solder horn driven by a membrane attached to the stylus. In 1898, Horace Boiled Down patented a arrangement for a loudspeaker driven by compressed air, then sold the rights to Charles Parsons, who was issued numerous additional British patents before 1910.

Another average call of not public drivers is in devices not primarily intended for high nature hearty reproduction, such as computers, toys, clock radios, and pocket sized music players. A single driver is less plush than several, and there is no duty for a crossover network, further reducing cost. In this use, high fidelity is at most a secondary consideration. Human hearing is able to tolerate listening to a reduced bandwidth, and upper harmonic synthesis can be given to to 'fill in' missing bass tones that the driver is too minuscule to usefully reproduce.
