31. The central, cylindrical pole piece surrounded by the voice coil is normally referred to as " the pole piece ". 32. In fact, the amp's output circuitry will be the main electrical load on the " voice coil current generator ". 33. Adhesives can melt, the voice coil former can melt or distort, or the insulation separating the voice coil windings can fail. 34. Adhesives can melt, the voice coil former can melt or distort, or the insulation separating the voice coil windings can fail. 35. In fact, the round panel attached to the voice coil bends in a carefully controlled way to produce full range sound. 36. The technology is designed to replace voice coil motor components, while improving speed, power consumption, and precision of the autofocus function. 37. The magnetic actuators were later replaced with hydraulic actuators and later yet the hydraulic actuators were replaced with voice coil actuators. 38. They reside in what would normally be the air gap around the voice coil , held in place by the speaker's magnet. 39. The circuit then relies on the inductance of the loudspeaker to keep the HF component from heating up the voice coil . 40. If all other conditions remain constant, the area of the voice coil windings is proportional to the power handling of the coil.
