Freischwingers consist of a permanent magnet and an excitation coil standing 90° to eachother, the moving part is the core of the coil or an induction loop, depending on the manufacturer. Because of the compact-wound coil the have poor cooling and low power handling. They went into extinction when permanent magnets became strong enough for dynamic speakers. The Telefunken in my link has a diaphragm similar to a Linaeum.
