While the Leslie speaker is still made and sold, similar effects can now be obtained via analogue electronic devices and digital emulation. Chorus and phase shifter devices can give an approximation of the sounds produced by a Leslie speaker. The Uni-Vibe, a four-stage phase shifter, was specifically marketed as a low-cost Leslie substitute for ...
Donald James Leslie (April 13, 1911 – September 2, 2004) was an American inventor best known for the Leslie speaker and its distinctive effect commonly used with the Hammond organ which helped popularize electronic instruments.
Leslie speaker - This rapidly spinning speaker, located in its own cabinet within the organ's console, added depth to the otherwise relatively flat sounds generated by the oscillators. Leslie speakers were not an invention of Thomas but were certainly used by them.
A diagram showing the key components of a Leslie speaker. It was performed by Brian and several session musicians, with no other members of the Beach Boys. The session sheet for the recording date carries the notation, "This is a working title only."
A Leslie speaker (best known through its historical and popular association with the Hammond organ) creates vibrato as a byproduct of tremolo production. As a Leslie speaker is moved by the rotating mechanism on which it is mounted, it moves closer to or farther away from any given object (such as a listener's ears) not also mounted on the ...
The Leslie speaker, most commonly associated with and predominantly used with the famous Hammond organ, takes advantage of the Doppler effect by using an electric motor to rotate an acoustic horn around a loudspeaker, sending its sound in a circle. This results at the listener's ear in rapidly fluctuating frequencies of a keyboard note.
In a Leslie speaker, the function of the switch is to control the speed of the oscillating horn, thus controlling frequency of the vibrato. It ranges from slowest (labelled chorale) to fastest (labelled tremolo). There is often an off position in between the two settings, depending on the switch.

The Leslie speaker is a specially constructed amplifier/loudspeaker cabinet used to create special audio effects such as vibrato, chorus and tremolo. The Leslie creates these effects by rotating the tweeters or horns or a spinning a sound-directing duct around the bass woofer speaker, which causes the Doppler effect .
