If your speaker cone is damaged, you may have a better chance of locating complete replacement. If thatis not possible, you will most likely have to rebuild it using some of the old parts where you can.
If you can remove the retainer for the spider, and the dust cap, you can see if the voice coil form is burned out, windings are loose, misallignment, or dirt.
The latter two are easily dealt with by cleaning and reallignment of the vocie coil to the center pole. Alignment is accomplished by shimming the space between the center pole and the voice coil. This can be done with paper/cardstock strips, or if the space looks like it will allow it- a wrap of craft paper, or heavy paper bag wrapped around the pole piece in a manner that leaves no overlap points. This would also be your procedure for reassembly on a comprehensive repair.
If the vocie coil form is good, and the windings have just come undone; rewinding the voice coil is not as intimidating as it may seem. Usually the best approach there is to start over rather than try to put the dislodged windings back into place. Match the wire guage, and count how many turns are on the voice coil, as well as the placement of the coil on the form, and winding direction.
If the cone is destroyed, but the coil form is okay, but windings are loose; you can use the paper cone repair procedure outlined on this site at: http://www.NostalgiaAir.org/NostalgiaAir/Articles/TheFlash/Flash03.htm , but forming those edges for the speaker to move freely, are a bit difficult to form with some papers. The way to cheat on that is to use a leather surround on the speaker. I show that procedure on a repair that I did as a repair to a Kellog that had been in need of some speaker work (it had a leather surround originally, but there is no reason that one cannot be used for other repairs).

If the coil form is destroyed, finding a complete replacement is most likely the only route to a repair.
You might find a repair cone, but those have been scarce in general.
: Want to rebuild a electrodynamic speaker.
: The voice coil is buzzing somewhere.
: Can I get the cone along with the voice coil?
: Where?
: Thanks again you all.
