By driving a current through the voice coil, a magnetic field is produced.

A second pole piece in turn surrounds the voice coil.

This product was considered unique for its dual 6-ohm voice coil system design.

Note that all specs are taken with the voice coils in parallel.

The voice coil and magnet form a linear electric motor.

Typically, they were driven by voice coils mounted on the moving part of the hammer.

They block the power amplifier from taking maximum control over the voice coil motion.

Enables the driver to have the same rise time, no matter where the voice coil is situated in the gap.

The remainder is converted to heat, mostly in the voice coil and magnet assembly.

Large magnet and voice coil for high power.

Its voice coil is wound with pure silver wire.

It features a 10inch ultra long-throw drive unit with high power voice coil.

The voice coil is attached by adhesives to the back of the speaker cone.

The higher the Bxl value, the larger the force generated by a given current flowing through the voice coil.

It is only a suspended cone, not attached to a voice coil or electrical circuit.

The image above shows two ways in which the voice coil is immersed in the magnetic field.

When the voice coil fails, the music stops.

A massive vented magnet and 50mm high temperature two layer voice coil.

Copper wire provides an easily manufactured, general purpose voice coil, at a reasonable cost.

A form of gain compression also takes place in loudspeaker voice coils when they heat up and increase their resistance.

Rotary voice coils are widely employed in devices such as disk drives.

Voice coils tend not to be as reliable as the stepping motors.

Behind the phase plug is an induction ring, matched by another at the other end of the voice coil.

Like a conventional driver, the Maggies use magnets and a voice coil to create sound by moving air.

The second cone has its own single layer voice coil and handles upper midrange.

Electronic control of the movement of the speech coil produces unbelievably good separation between vocal and instrument sound that can at best be compared only to the original performance.

The changing signal through the speech coil is translated into movement of the coil due to magnetic attraction/repulsion (remember from schooldays - like poles repel, opposites attract).
