Walk the independent claim. Meta's grant US12026313B1, "Haptic device with coupled resonance at tunable frequencies" (issued July 2, 2024; inventors Dongsuk Shin and Sai Sharan Injeti), is a granted patent. Its CPC mix — G06F 3/016 haptics plus H02K 33 vibration-motor classes — marks actuator-hardware art aimed at richer tactile output.
The element that does the work is frequency tunability through coupled resonance. A simple resonant actuator is efficient but locked to one frequency, giving one characteristic buzz. The claim's contribution is a coupled-resonance design whose frequency can be tuned, so a single actuator can produce a range of distinct haptic sensations — sharper taps, different textures — across frequencies.
What it reads on is the haptic hardware in VR controllers and wearables, where conveying rich, varied tactile feedback is central to immersion. Meta's Reality Labs has a clear product motive for expressive haptics, and the claim protects an actuator architecture built to deliver them.
Read against Apple's single-actuator, waveform-driven multi-mode approach and Microsoft's two-independent-actuator design, this is a third philosophy: change the actuator's resonant frequency rather than its drive waveform or count. The haptics field is a real contest of architectures, and each major player's claims reflect a different bet.
Scope discipline: the claim protects the recited tunable coupled-resonance device, not haptics generally and not fixed-frequency actuators. A device using a fixed-resonance actuator, or achieving variety purely through drive waveforms, operates outside it. The defensible element is the tunable coupled resonance.
Granted status makes US12026313B1 a live consideration in immersive haptics. For a strategist mapping the haptics landscape, it marks Meta's position — a hardware-side bet on frequency tunability, distinct from the software-side and multi-actuator approaches its rivals hold.
