The new architecture replaces star wiring with a serial bus. Smart speakers receive both data and power directly from the bus
Revolutionizing Car Audio Through Distributed E/E Architectures
My patent application EP 4601324 A1 introduces a distributed electrical/electronic (E/E) architecture for car audio systems. Instead of relying on heavy centralized amplifiers and complex star-topology wiring harnesses, this approach integrates amplification directly into smart loudspeakers connected by a serial bus. The result is a system that is lighter, scalable, faster to develop, and perfectly aligned with the automotive industry’s shift toward zonal computing.
