Double Coil Speaker

摘要

An audio system that comprises an electro-acoustic transducer connected to a first driver circuit and a second driver circuit, which electro-acoustic transducer comprises a first coil stacked on a second coil mechanically linked to a membrane, with the coils oscillatingly suspended in the magnetic field of a permanent magnet focused by a pole plate, wherein the first coil and the second coil are mechanical arranged symmetrical to the pole plate in a rest position.
