Knowledge of membrane transducers do not provide the entire musical quality. The speed of movement is too slow owing to the inertia of the coil membrane mass. The method uses a constant electromagnetic field as reference and at least a variable electromagnetic field, compelling the air particles to be activated to the rhythm of an audio modulation. An apparatus consisting of at least a primary winding electrically connected in series or in parallel to an electrical circuit for audio powering a loudspeaker, generates a depolarisation of the air particles. Said apparatus is a fixed motor with revolving field and also a transformer, by its being an inductance, thereby enabling to eliminate blast filter components, completely or partly. The apparatus and the method constitute an acoustic complement for sound reproduction, in all audio and audio-visual fields. |
