Size Barrier Broken: Vybronics' 4mm Coin LRA Claimed as the Smallest on the Market
Vybronics has introduced the VG0415001W-240H linear resonant actuator (LRA), a coin type haptic vibration motor developed for space-constrained wearables such as smart rings and hearables. It measures 4 mm in diameter by 1.5 mm thick and weighs only 0.1 gram.
Winter Park, FL, November 10, 2026 --(PR.com)-- Vybronics has introduced the VG0415001W-240H linear resonant actuator (LRA), a coin type haptic vibration motor developed for space-constrained wearables such as smart rings and hearables.
Measuring 4 mm in diameter by 1.5 mm thick and weighing only 0.1 gram, the VG0415001W-240H is claimed to have the smallest diameter of any coin type LRA vibration motor currently on the market. The previous smallest coin LRA measures 6 mm in diameter, making this device a full 2 mm smaller in diameter and significantly thinner.
The device produces a minimum vibration acceleration of 0.12 Grms referenced to a 10 gram sled, which is approximately twice the weight of a smart ring.
The VG0415001W-240H operates at a resonant frequency of 240 Hz and is driven at a rated 0.4 Vrms AC sine wave, with an input range of 0.1 to 0.42 Vrms. The actuator offers a rise time of 40 msec maximum and a fall time of 60 msec maximum for crisp, responsive haptic effects, The drive signal is normally supplied by an LRA driver IC; see our product page for details.
The device connects via a flexible printed circuit (FPC) or wire leads for direct integration into compact smart ring assemblies. Vybronics can supply the VG0415001W-240H as shown or with a customer designed FPC.
Typical applications include smart rings, hearables, and other devices (<=10 grams) that requires haptic / vibration feedback.
The VG0415001W-240H is available now. For datasheets, samples, pricing, and availability, visit www.vybronics.com or contact sales@vybronics.com.
