MicroLED AR smart glasses uses MEMS speakers
Indian developer Focally has used MEMS speakers from USound in Austria for its first augmented reality (AR) smart glasses.
The two-way MEMS speakers were developed by USound in Graz are combined with a microLED full colour display engine and features fully transparent see-through waveguide with a field of view (FOV) of 30 degrees.
The glasses integrate USound’s patented two-way audio system with MEMS tweeter and electrodynamic woofers, and dual microphones for noise cancellation and spatial audio. The glasses also include an accelerometer, gyroscope, magnetometer, environmental, gas composition and IR.
Focally is already working on its second-generation prototype with vision capabilities and advanced compute capabilities. An optimized computer platform will be launched to developers and early adopters later in 2023, but Focally has not disclosed the supplier of the microLED engine or the compute platform, although this is most likely to be Qualcomm’s Snapdragon.
The USound MEMS loudspeakers require up to 50% less space and consume 80% less energy and offer a greater frequency range per unit of area.
“Once more, it is demonstrated how our compact MEMS speakers-based audio solutions enable manufacturers to add more features to hearables and wearables for an improved user experience,” says Andrea Rusconi, CTO, and Co-Founder of USound.
“We are excited to showcase our first demonstration of making Contextual Augmented reality near and accessible by integrating cutting edge technologies into an acceptable and wearable form factor. Stay tuned with us for exciting offerings,” said Sagar Madliyavar CEO and Founder of Focally.
Focally is one of the several companies using the USound MEMS speakers that will launch wearables and hearables products to the market in 2022 and through 2023.
