Operation
When the compressed air is allowed to act on the diaphragm, it vibrates to produce sound waves which passes through the horn and gets amplified in it. The simple arrangement consists of a diaphragm with an air inlet port. The diaphragm is contained in a conical shaped curved structure horn, which helps in amplifying and spreading the sound.
