Cars as Speakers? Ford’s Patent Aims to Redefine Outdoor Sound

Ford has filed a patent for a futuristic audio system that uses autonomous vehicles — and possibly drones — to create immersive surround sound experiences outdoors.

Ford is exploring the idea of turning its future vehicles into a dynamic, mobile audio system — capable of delivering stereo, surround, or even overhead sound outdoors. While it’s still at the patent stage, the concept reimagines the car as not just a method of transport, but a speaker in a reconfigurable soundstage.

According to a recently published U.S. patent application, Ford envisions a “multi-vehicle audio system” that uses autonomous cars equipped with synchronised sound gear to create immersive audio environments. The vehicles would wirelessly sync with one another and automatically arrange themselves around an audience, a stage, or a projection screen — each car effectively acting as an individual speaker in a much larger multi-channel system.

For example, two vehicles could be parked on either side of a crowd to provide stereo sound, while four or more could be positioned to deliver surround sound — with vehicles playing different audio channels depending on their location. And thanks to autonomous control, they could reconfigure themselves as needed, adapting to different content types or venues.

The system also goes further, accounting for acoustic optimisation. Vehicles could open windows, doors, or even adjust their roofs to fine-tune the audio presentation, depending on whether the equipment is installed inside the cabin or mounted externally. Built-in GPS would allow each vehicle to understand its relative position, automatically selecting the correct channel and delay timing for precise synchronisation.

While Ford’s patent includes the possibility of using regular cars (so long as they’re properly positioned), the more future-focused version relies on full autonomy — and possibly even drones. The document suggests airborne audio units could introduce verticality to the setup, enabling a kind of portable Dolby Atmos effect without permanent infrastructure. In theory, a full 360-degree soundscape could be created anywhere from a music festival to an outdoor cinema screening, with minimal setup time and no need for traditional PA systems.

Filed under U.S. patent number US20230121724A1, the application is the latest in a string of imaginative ideas exploring what autonomous vehicles could be used for beyond transportation.

Of course, like many patents, this concept may never make it into production — but the idea of cars and drones forming an on-the-fly surround system has plenty of appeal for outdoor events, entertainment brands, and audio manufacturers alike. And in a world where immersive sound is increasingly becoming part of the premium AV experience, Ford’s vision might not be as far-fetched as it first appears.
