Movable coil for loudspeaker and microphones without the classical carrier of the movable coil. The movable coil is made of electrically conductive and isolation strips wound turn over turn, so that the isolation strip is wider than the electrically conductive strip, and their difference in width is used as a coil carrier. Empty spaces between turns of isolation strip must be filled up with varnish or glue, for better solidity of the coil carrier. In this way constructed movable coil has greater fill up by electrical conductors and decrease of isolation material in the gap of the magnetic field. By this construction of the movable coil, is a greater power and sensitivity of the movable coil achieved and thus also a greater working precision of the movable coil.
