The geometry <strong>of</strong> the speaker in an enclosure is<br />

shown below. Note that ¼ symmetry is used:<br />

For the speaker, forces are<br />

exerted on the voicecoil,<br />

causing it to move.<br />

The voicecoil moves the cone<br />

which is what displaces the<br />

air to produce sound.<br />

The surround and spider<br />

connect and stabilize the cone<br />

to the rigid frame.
