Vybronics Introduces Smallest Coin Type LRA for Wearables

Vybronics, a company specializing in haptic vibration motors and engineering services, has broken a size barrier in the wearable technology market by introducing the VG0415001W-240H linear resonant actuator (LRA). This innovative device measures 4 millimeters in diameter by 1.5 millimeters in thickness and weighs a mere 0.1 gram, making it the smallest coin type LRA vibration motor on the market.

The VG0415001W-240H is designed for space-constrained wearables such as smart rings and hearables. Its compact dimensions and lightweight make it an ideal choice for devices that require minimal bulk. The actuator is capable of producing a minimum vibration acceleration of 0.12 Grms when referenced to a 10 gram sled, which is approximately twice the weight of a typical smart ring. This ensures a noticeable and effective haptic feedback experience for users.

Operational at a resonant frequency of 240 Hz, the VG0415001W-240H is driven by 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 milliseconds maximum and a fall time of 60 milliseconds maximum, ensuring crisp and responsive haptic effects. These features make the VG0415001W-240H a versatile solution for various applications, including smart rings, hearables, and other devices weighing up to 10 grams that require haptic or vibration feedback.

The VG0415001W-240H is now available for integration into compact smart ring assemblies via a flexible printed circuit (FPC) or wire leads. Vybronics can supply the device as shown or with a customer-designed FPC, providing flexibility for manufacturers to tailor the product to their specific needs. The company serves customers worldwide from sales offices in the USA and China, with factories located in Vietnam and China.
