  1. Speaker Design A. Ryan Parker

  2. Diaphragm Usually manufactured with a cone or dome shaped profile to accurately reproduce the voice coil signal waveform if replications aren’t precise acoustical distortion could occur

  3. Frame/Basket Houses speaker and its components while protecting the magnet gap and voice coil (over heating)

  4. Pole Piece Serves as magnet in center of speaker

  5. Suspension System Spider & Surround Suspension System: Keeps coil centered and serves as a restoring force for the cone after vibration. Spider: Connects frame and diaphragm or voice coil Surround: Ring of fabric attached to outer diaphragm & frame

  6. Voice Coil Copper or aluminum wire wrapped around a drum located in the magnetic gap where it moves

  7. Tags/Lead Wires Used to wrap voice coil

  8. Dust cap Sometimes lowers acoustic quality because it hinders the overall cone design

  9. How it all works • “An electromagnet is placed n front of a permanent magnet (pole piece). The permanent magnet is fixed firmly into position whereas the electromagnet is mobile. As pulses of electricity pass through the coil of electromagnet the direction of its magnetic field is rapidly changed. Meaning that this is attracted to and repelled from the permanent magnet, vibrating back and forth. “ -http://www.physics.org
