magnetostat

Magnetostats are flat-panel loudspeakers, comparable to electrostats, with the difference that the diaphragm

is moved by a magnetic field and not by an electrostatic one. The freely moving diaphragm is a lightweight plastic foil diaphragm with a metal layer vapour-deposited in strips. It is located in the middle between the permanent magnets arranged on both sides. When current flows through the metal coating, the membrane is moved in one direction or the other, depending on the direction of the current flow, which produces the sound

.

ostats are suitable for the high-frequency and mid-frequency ranges. The diaphragm sizes range from about 2 cm to 10 cm. There are such speakers

with much larger diaphragm areas in the metre range also for the low frequency range.

ostats are comparable to electrostats in their characteristics. They have a good impulse response and are not very pronounced in the low frequency range. Therefore they are often tweeters.
