SPEAKER

An electronic speaker typically consists of the following components:

1. Cone or Diaphragm: The cone or diaphragm is the main moving part of the speaker. It is usually made of lightweight materials such as paper, plastic, or metal, and it vibrates in response to the electrical signals received.

2. Voice Coil: The voice coil is a coil of wire attached to the back of the cone or diaphragm. When an electrical current passes through the coil, it generates a magnetic field that interacts with the permanent magnet of the speaker, causing the cone or diaphragm to move back and forth.

3. Magnet: The magnet is a permanent magnet positioned behind the voice coil. It provides a fixed magnetic field that interacts with the magnetic field generated by the voice coil, resulting in the movement of the cone or diaphragm.

4. Suspension System: The suspension system, including the spider and surround, holds the cone or diaphragm in place and allows it to move freely while maintaining its position within the speaker frame.

5. Frame or Basket: The frame, also known as the basket, is a rigid structure that holds all the components of the speaker together. It provides stability and support for the cone or diaphragm.

When an electrical audio signal is applied to the voice coil, it creates an electromagnetic field that interacts with the permanent magnet. This interaction causes the voice coil and attached cone or diaphragm to vibrate, producing sound waves that correspond to the original electrical signal. These sound waves are then radiated into the surrounding air, allowing us to hear the reproduced audio.
