- A SOFT IRON CORE in the coil
- 4 FACTORS WHICH SPEED IT UP
- Loudspeaker
- 1. A.C electrical from an amlifier are fed to a coil of wire in the speaker.
- 2. The coil is surrounded by a permanent magnet, so the A.C signals cause a force on the coil and make it move back and forth
- 3. These movements make the cone vibrate and this creates sounds
