Electrodynamic speakers

The innovative character of the invention is related to the operating principle relying on an ironless motor and ferrofluid seal suspension.



One of the study's purposes was to calculate the modes and frequencies inherent to speaker vibration, to isolate the bending modes and shift the frequencies.



For materials we chose aluminum laminated with unidirectional carbon sheets combined with very low thickness walls. The investigations have focused on the impact of the dome's geometric profile.
