Introducing The Smart Glass Speaker by Hypersound




This speaker makes use of transparent glass to drive sound in a highly focused
beam directly in front of them while being inaudible
outside the beam’s range. Welcome to never knowing
why you’re hearing ads all the time—our Blade Runner
hell future has arrived.
The exact means the Glass uses to generate a tight
beam of sound isn’t specifically disclosed, but
according to the company, the glass is layered with
transparent films. Like other highly directional
speakers, what’s being generated isn’t audible sound
waves but rather ultrasonic waves. Based on other
products of this nature, it’s safe to guess that as those
ultrasound waves pass through the glass/film
sandwich they’re modulated in such a way that they
become audible again while traveling in a straight
line, though the details on specific improvements will
likely remain trade secrets. Acoustics is, to put it
mildly, a bizarre science.
While these see-through speakers probably won’t
replace more traditional options for the home market,
there are some interesting applications for the
technology. According to a press release , Turtle Beach
may try to integrate the technology into things we
already make out of glass, like computer monitors and
car windshields—things that are already easy to break
and expensive to fix. But heck, being able to crank a
laptop to full volume without bothering the person
sitting next to you would be worth it.





Similar to other Hypersound products, the Glass might
also be useful for people with hearing loss. Because the
sound that directional speakers produce is so focused
it’s more like wearing headphones than what you
would think of as “speaker sound.” For that same
reason, Hypersound Glass might find its way into
things like ATM screens, where privacy is key.
Highly directional sound isn’t a particularly new
concept—with early entrants in the market like
Holosonic producing commercial models since 2000—
it just never quite caught on at a consumer level. Glass
also isn’t a novel material for driving sound: We’ve
seen plenty of glass speakers in the past. But the two
existing technologies have never been combined
successfully before. Turtle Beach is mainly known for
its gaming-focused products, but the company appears
to be putting serious resources behind these laser-like
speakers.
