(1) A piece of ferromagnetic material used to control the distribution of magnetic lines of force; that is, it concentrates the lines of force in a particular place or evenly distributes the lines of force over a wide area. (2) The shaped magnetic material upon which the stator windings of motors and generators are mounted or wound.
The piece of metal in a speaker that concentrates and focuses energy from the speaker magnet to create a magnetic circuit. Because heat can build up during this process, many pole pieces are vented for cooler, more efficient operation.
The cylindrical core of a loudspeaker motor, one end of which forms the inside of the magnetic gap within which the voice coil moves.
A magnetic material that channels a magnetic field from a magnet into a pipe material.
The metal pole attached to the magnet structure in a speaker's motor assembly that is surrounded by the voice coil, forming the inside wall of the gap.
A pole piece concerns the metal piece in a speaker that concentrates and focuses energy from the speaker magnet into creating a magnetic circuit. Because heat can accumulate during this process, many manufacturers vent pole pieces for cooler, more efficient operation.
