Noun
(electronics) A coil of wire attached to the apex of the cone of a loudspeaker that provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.
(electronics) A similar mechanism that positions the disk read-write head in a computer hard disk drive.

For instance, the shape of the pole piece affects the magnetic interaction between the voice coil and the magnetic field, and is sometimes used to modify a driver's behavior. Source: Internet
In fact, the round panel attached to the voice coil bends in a carefully controlled way to produce full range sound. Source: Internet
Instead, the voice coil is inductive, the driver has mechanical resonances, the enclosure changes the driver's electrical and mechanical characteristics, and a passive crossover between the drivers and the amplifier contributes its own variations. Source: Internet
Some early PC drives used a stepper motor to move the heads, and as a result had seek times as slow as 80–120 ms, but this was quickly improved by voice coil type actuation in the 1980s, reducing seek times to around 20 ms. Source: Internet
The advantage of aluminum is its light weight, which raises the resonant frequency of the voice coil and allows it to respond more easily to higher frequencies. Source: Internet
