When the various current of an audio sign is passed through the coil, it creates a varying magnetic area that reacts against the static magnetic area, exerting a varying pressure on the coil inflicting it and the attached diaphragm to vibrate.

Some stereo earbuds are wireless, using Bluetooth connectivity to transmit the audio sign by radio waves from source devices like cellphones and digital gamers.
Today they are typically used only in in-ear headphones and hearing aids, where their excessive effectivity and diminutive dimension is a serious benefit. They typically are restricted at the extremes of the listening to spectrum (e.g. below 20 Hz and above sixteen kHz) and require a better seal than other kinds of drivers to ship their full potential. Higher-end models might employ a number of armature drivers, dividing the frequency ranges between them utilizing a passive crossover community. A few combine an armature driver with a small moving-coil driver for elevated bass output. They require an influence supply, normally a battery, to drive their circuitry. Active noise cancelling headphones can attenuate ambient noise by 20 dB or extra, however the active circuitry is especially efficient on fixed sounds and at decrease frequencies, somewhat than sharp sounds and voices.
