Part Number: No.20 horn

It is an element that converts electrical signals into sound, also known as a loudspeaker.
Horn is actually a kind of electrical energy into sound conversion equipment, when different electronic energy to the coil, the coil produces a kind of energy and the magnetic field of the magnet interaction, this interaction caused by the vibration of the paper disc, because the electronic energy at any time change, the coil of the horn will be forward or backward movement, so the speaker will follow the movement of the paper disc, which this action makes the air sparse and dense degree of change and produce sound.

Part Function:Sound Playback
