2. Diaphragm (acoustics) - Wikipedia

   en.wikipedia.org/wiki/Diaphragm_(acoustics)

   The cone stiffness/damping plus the surround's linearity/damping play a crucial role in accuracy of the reproduced voice coil signal waveform. This is the crux of high-fidelity stereo. The surround may be resin-treated cloth, resin-treated non-wovens, polymeric foams, or thermoplastic elastomers over-molded onto the cone body.

3. Compression driver - Wikipedia

   en.wikipedia.org/wiki/Compression_driver

   Horn-loaded compression drivers can achieve very high efficiencies, around 10 times the efficiency of direct-radiating cone loudspeakers. They are used as midrange and tweeter drivers in high power sound reinforcement loudspeakers , and in reflex or folded-horn loudspeakers in megaphones and public address systems .

4. Electrodynamic speaker driver - Wikipedia

   en.wikipedia.org/wiki/Electrodynamic_speaker_driver

   This cone, dome or other radiator is mounted at its outer edge by a flexible surround to a rigid frame which supports a permanent magnet in close proximity to the voice coil. For the sake of efficiency, the relatively lightweight voice coil and cone are the moving parts of the driver, whereas the much heavier magnet remains stationary.

5. Loudspeaker enclosure - Wikipedia

   en.wikipedia.org/wiki/Loudspeaker_enclosure

   These speaker grilles are a metallic or cloth mesh that are used to protect the speaker by forming a protective cover over the speaker's cone while allowing sound to pass through undistorted. [ 3 ] Speaker enclosures are used in homes in stereo systems, home cinema systems, televisions , boom boxes and many other audio appliances.

6. Electrical characteristics of dynamic loudspeakers - Wikipedia

   en.wikipedia.org/wiki/Electrical_characteristics...

   The moving system of the loudspeaker—consisting of the cone, cone suspension, spider, and voice coil—can be modeled as an effective mass (spring–mass system), a mass suspended by a spring. This system has a characteristic mass and stiffness, and a resonant frequency at which the system will vibrate freely.

7. Voice coil - Wikipedia

   en.wikipedia.org/wiki/Voice_coil

   This magnetic field causes the voice coil to react to the magnetic field from a permanent magnet fixed to the speaker's frame, thereby moving the cone of the speaker. By applying an audio waveform to the voice coil, the cone will reproduce the sound pressure waves, corresponding to the original input signal.
