February 15, 201213 yr The cone is the "face" of the driver, the circular part that you can visually see moving inward and outward.On the other side of the cone, directly in the center, is the voice coil, shaped like a tube, often times made of paper, and wire is wrapped around it (coil).Also connected to the cone and voicecoil is a stiff disk with wrinkles in it. This is the spider / spider assembly. It keeps the voice coil aligned during travel, supplies a force causing the voice coil to return to it's resting position when no power is being applied. Sometimes the tinsel leads are woven in, other times they go above the spider. The tinsel leads carry the signal to the voice coil.The voice coil sits in a hole drilled through the motor (metal and magnets), this is called the gap. The front plate, pole piece, and back plate are often made of metal and used for creating a path for the magnetic field from the magnet.A/C current is applied to the voice coil and this creates an electromagnet. A/C current is in the form of a sine wave, so the polarity of the electromagnet changes in relation to the cycle of the sine wave. This polarity change causes the voice coil to be pulled and pushed in the gap from the outer magnetic field. The cone of the driver then moves inward and outward since the voice coil is connected directly to it. As the cone moves, so air is displaced, and sound is created.There are several different geometries used for positioning the voice coil in the gap, all have their benefits and weaknesses. Of course there are tons of other factors that effect a speaker's frequency response.
