STMicroelectronics and USound Demonstrate Immersive Listening Experiences with Advanced Micro-Speakers in 3D-Sound Headphones at MWC 2018
- MEMS speakers developed by USound and manufactured by
STMicroelectronicscombine minuscule size, low profile, and high efficiency enabling multiple speakers in wearable form factors
- Headphone demonstration shows how hardware-based 3D-audio, enabled by these tiny speaker units, boosts augmented/virtual reality
The demonstration presents over-the-ear headphones that contain 14 of the miniature, low-profile speakers to create lifelike 3D-audio effects. These allow wearers to localize events occurring to the right, left, behind, or elsewhere, in a sonic virtual or augmented reality, giving a rich and immersive user experience that could enhance visual AR and VR worlds. With their large bandwidth and high-quality bass, the speakers are capable of highly realistic sound reproduction.
"The demonstration at MWC 2018 shows how the tiny dimensions and good sound quality of these advanced speakers enable lifelike 3D sound," said
USound's micro-speakers feature industry-unique, high-precision piezo-electric actuators, which simultaneously enable small size, low power consumption, low heat dissipation, and very high sound quality, unmatched by conventional electro-dynamic balanced-armature speakers. Audio equipment producers can take advantage of these attributes to create hardware-based wearable 3D-audio products that accurately recreate a real acoustic environment.
ST's Piezo-electric Transducer technology (PeTra) and MEMS (Micro Electro-Mechanical Systems) manufacturing processes provided the keys to realizing the manufacturing of such tiny speakers as market-ready products within an aggressive project timeline, leveraging proven techniques similar to conventional MEMS and CMOS (Complementary Metal-Oxide Semiconductor) chip fabrication. The actuators are extremely small, reliable, and can be manufactured economically in high volumes.
The demonstration of USound's silicon MEMS speakers takes place at the ST booth, Hall 7, Stand 7A61,
