Haptics LRA Expansion

Announcement

PUI Audio introduced Haptics in 2022, ensuring that when a tactile response or alert is necessary it can be felt clearly. Our commitment to innovation continues as we expand our haptics portfolio with new products tailored for diverse applications.

PUI Audio is excited to unveil the addition of a surface mount Linear Resonant Actuator (LRA) featuring patent-pending design, making it reflowable and washable through seamless automatic pick and place operations.

HD-LA1307-SM measures just 13mm x 13mm and delivers 1.8G maximum acceleration in a linear direction at a resonant frequency of 154 Hz to provide immediate, high-resolution tactile feedback. Our new waterproof IP rated surface mount product facilitates seamless integration into various end applications, such as virtual reality environments, gaming consoles, medical simulators, handheld devices, and consumer and industrial control interfaces.

Key Advantages of Linear Resonant Actuators

Linear Resonant Actuators (LRA) Haptic devices are AC-driven parts and produce a vibration in two directions along one axis. In default orientation, this is in the Z-axis (but can be adjusted using different mounting directions). A change in the frequency or amplitude of the driving signal will directly correspond to changes in vibration produced by the actuator.

A key benefit of using an LRA is the linear response- there is no ramping time for the device to reach a threshold for proper actuation like an ERM. The user will feel a vibration as soon as the coil is excited, and the mass moves up or down.

LRA devices fit into some of the smallest form factors available for haptic actuators. They are incredibly power efficient, making them the most popular choice in products such as wearables and smartphones. Designers using LRA devices in their products can take advantage of high-resolution, responsive vibration patterns to deliver information to the user. These vibrations are often supplementary to another stimulus, like audio effects or information on the devices’ screen, but also may be used as an independent source of information for a user. The rapid linear response of LRA devices allows product designers to design custom vibration patterns to fit the needs of any situation.
