Change the voice coil or the cone or the magnet or the air gap comes to mind.

It is the fine wire coil around the magnet with extremely loose multi stranded very fine wire so that it can allow the coil to move easily up and down your magnet flexing a million times without fatigue cracking that would disrupt current flow.

BTW the voice coil is firmly attached to paper cone and when you think about it, a speaker is small linear motor.

Referring to to the above single voice coil above it is a cut away.

The multiple voice coils probably think the design engineers see some sort of advantage in doing that way.

Thats not exactly how speakers work.Assuming I understand what you have done. A picture or two would help.

Normally a loud speaker will have a magnet - generally cylindrical, with a coil of fine wire wrapped round the magnet - loose so it can move up and down.

Applying your audio to this coil will cause it to move.

To make the sound loud the coil is connected to a paper or plastic cone to spread the sound.

Have you done something like this picture?

It depends on how you have used it. But it depends on how you use it and how the magnet is magnetized.

The illustration below might work.
