Gotta go eat but I'll post these pics real quick. Feel free to dig for any more info that might be floating out there.
Sounds Great introduced the nano-semiconductor technology as part of the Taiwan Startup CES 2021 showcase. The concept of a speaker chip, with a minimal size of just 1mm x 1mm x 0.2mm was pitched as an ideal solution to extend battery life in true wireless earbuds with the possibility to create larger chips optimized for lower frequency ranges that could be combined without impact consumption in a major way. But the potential applications for Sounds Great' Semicon Speaker technology are much larger and that's what the company is promoting at this year's CES.
SDS also reproduces stereo sound in a 7x6mm form factor with independent tweeters, mid-range, woofers and even subwoofers focusing on very low frequency, resulting in sound pressure level optimization with extended frequency response.
An advantage mentioned specifically by Ted Zhou for this technology is the ability to customize the sound curve with precision, acting over very narrow bands in the signal, instead of amplifying or attenuating entire frequency bands. In its website the company already discusses possible array customizations from a 2-speaker system to a 4-speaker system, with or without Bass Reflex Port.
Sounds Great is also working on the development of multiple diaphragm materials on each independent speaker, creating SDS arrays with richer timbres for enhanced sound reproduction. "SDS' ability to create powerful and quality sound from compact spaces is a precursor to even more revolutionary audio applications such as hidden speakers on eyeglasses, AR/VR solutions, smart furniture, and even redefine car stereo architecture," adds co-founder Edmund Wu.
