Diaphragm Speakers

Diaphragm Speakers:-This speaker is related to the electrodynamic loudspeaker in that it uses magnetic fields to move an element, however its shape is different. This speaker has the coil directly mounted on the diaphragm. Below is an example of a flat panel style diaphragm speaker. The copper coils have been wrapped around the base of the clear plastic bulges in the photos below. The entire clear plastic sheet below moves to create sound. See the diagram below. This is a heavier speaker than the flat panel speakers above.
