The American company Resonado Labs offered an alternative version of the speaker. Instead of the traditional design with a diffuser and a sound coil on two suspensions, internal and external, the Resonado offers two oppositely directed diffusers powered by a single sound coil. Moreover, the coil was made flat and placed between the rod magnets. The design was named Flat Core Speaker (FCS).
The technology in its” pure form ” debuted at CES 2020. This year, Resonado presented at the exhibition concepts of speakers based on FCS – options for an outboard and smart speaker. Prototypes of floor acoustics and a flat subwoofer with FCS drivers are already ready (at least in the renderers).
It is clear that such a bi-directional emitter will be especially good for dipole-type acoustics. It provides an almost uniform radiation pattern. At the same time, the driver itself turned out to be flat and, importantly, easily scalable — it is easy to dial a flat panel of any size from the FCS speakers.
The appearance of a new technology in real devices is possible soon. Resonado Labs plans to distribute its technology by selling licenses for the production of FCS drivers to speaker manufacturers in two versions: the basic FCS SingleCore and the dual-drive FCS DualCore. It is also important that the replication of the new product does not require any new technological equipment and materials.
