| Keywords: Reflex loudspeaker animation.gif folded horn speaker widely used in public address systems It consists of a specialized diaphragm loudspeaker called a compression driver a attached to a metal horn d The driver has a diaphragm <font color blue > blue </font> driven to vibrate by the audio signal current flowing through a coil of wire <font color red > red </font> between the poles of a cylindrical magnet <font color green > green </font> The horn serves to couple the diaphragm more efficiently to the air allowing it to radiate more of its energy as sound than a conventional horn speaker making it louder The horn sound path must be several feet long so to make the speaker more compact the sound path is folded into a zigzag shape by several concentric exponentially-widening ducts The sound waves pass forward through an inner tube b in the central projection in the horn back through a larger concentric tube c then out through the surrounding horn d <br /><br /> In this animation the rate of vibration of the diaphragm and the speed of the sound waves are shown greatly reduced The logo in the lower right corner is not a part of the diagram and was added by the gif animation software 2012-07-16 own Chetvorno Reflex loudspeaker animation 2 gif is an improved more realistic version of this animation cc-zero Uploaded with UploadWizard Horn speakers Public address speakers Loudspeaker schematics Animated diagrams Animated GIF | ||||
