What Do you Need to About Horn Speakers?
Horn loudspeakers are more efficient; they can usually offer ten times (10 dB) more sound power than a cone speaker from a given amplifier output. Hence horns are extensively used in public address systems, megaphones, and sound systems for huge venues like theaters, auditoriums, and more. It utilizes an acoustic horn to spruce up the overall effectiveness of the driving element(s). A common form incorporates a compression driver which generates sound waves with a small metal diaphragm vibrated by an electromagnet, connected to a horn, a flaring duct to conduct the sound waves to the open air. The horn functions to boost the coupling performance between the speaker driver and the air. The horn can be conceived as an "acoustic transformer" that offers impedance matching between the moderately dense diaphragm material and the less-dense air. The effect is superior acoustic output power from a provided driver. Besides the driver, the narrow part of the horn is termed the ...
