Magnepan has used several different technologies in constructing their magnetostatic speakers.All Magnepan speakers are based on flexible ferrite magnet strips (like refrigerator magnets), 0.060" (1.5 mm) thick, typically cut to either 1/4" (6 mm) wide (mid-bass) or 1/8" (3 mm) wide (tweeters) and more or less the length of the speaker.
Schematic showing an electrostatic speaker's construction and its connections. The thickness of the diaphragm and grids has been exaggerated for the purpose of illustration. An electrostatic loudspeaker (ESL) is a loudspeaker design in which sound is generated by the force exerted on a membrane suspended in an electrostatic field.
Planar magnetic speakers (having printed or embedded conductors on a flat diaphragm) are sometimes described as ribbons, but are not truly ribbon speakers. The term planar is generally reserved for speakers with roughly rectangular flat surfaces that radiate in a bipolar (i.e. front and back) manner. Planar magnetic speakers consist of a ...
A magnetostatic loudspeaker is a dipole loudspeaker that is similar to an electrostatic loudspeaker but uses high currents instead of using high voltages. Permanent magnets provide a static magnetic field and wires or strips carrying audio frequency currents are bonded to a thin diaphragm. The current flowing in the conductors interacts with ...
All speaker drivers have a means of electrically inducing back-and-forth motion. Typically there is a tightly wound coil of insulated wire (known as a voice coil) attached to the neck of the driver's cone. In a ribbon speaker, the voice coil may be printed or bonded onto a sheet of very thin paper, aluminum, fiberglass or plastic.
Monsoon's speaker designs were based on planar magnetic technology, licensed from Eminent Technology who developed the original concept. However, despite the brand's popularity among computer users – or perhaps because of it – within the next couple of years the assets of Sonigistix were purchased by Eastech, an Asian technology company ...
