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.

“A haptic device with coupled resonance at tunable frequencies includes an actuator, a first structure coupled to the actuator, a second structure coupled to the first structure and separate from the actuator, and at least one local mass coupled to the first or second structure; the first and second…”— U.S. Patent No. 12,026,313 source

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.
