THE LATEST TVs HAVE NO SPEAKERS? SOUNDS GOOD TO ME!


You can call it “Acoustic Sound Technology” or you can call it “Crystal Sound” or even “Planar Speaker Technology” — whatever you call it, there’s a lot more improvements in today’s (and tomorrow’s) TVs than just the quality of the picture. How, and perhaps just as importantly, where we get the sound from is also undergoing a dramatic change, and based on the early results, television LISTENING will never be the same.

Sony got the head start with their Acoustic Sound Technology when they first introduced their landmark Bravia A1Emodel to the public at Video & Audio Center’s Woodland Hills Technology Showroom just over a year ago in March of 2017. While the picture was certainly flawless, the star of the event was the Acoustic Sound Technology—where the sound emanated from the vibrating screen.
 
At this year’s Consumer Electronics Show in Las Vegas, LG, the pioneer in consumer OLED TV technology proudly announced the addition of Crystal Sound to their upcoming OLED line of TVs, and just like Sony, instead of producing the audio with traditional speakers, Crystal Sound uses the TV screen itself to produce the sound. With special “exciters” placed behind the ultra-thin OLED panels that produce sound by vibrating the display, the end result is a more geotargeted sound, which seemingly comes directly from the objects on the screen being shown.

This is nothing new in realm of sound technology, according to Philip Jones, Product Technology Manager at Sony Electronics, “It’s a lot like a pair of planar headphones,” Jones explains. In the realm of headphones, planar models are often the most-expensive options due to their sonic fidelity. “The challenge is, how do you move the plane, which in this case is the screen. In a headphone, you can do electrostatic technology, you can do it with magnets. But this is vibrating glass.” 


Planar speaker technology was a dramatic departure from traditional dynamic speakers. The “planar” in planar magnetic sound referred to the magnetic field that’s distributed in the same plane to the diaphragm that produces the sound—but today’s technology substitutes the thin glass of the TV screen for the diaphragm and when the circuit is energized with an audio signal, it interacts and produces a force that vibrates the screen hypersonically, thereby creating sound.
Planar sound technology offers numerous benefits, including generating far greater responsiveness, its’ capable of producing a wider frequency ranges across high, mid and low ranges with less distortion, they are far more durable with less moving parts, and of course it’s really cool to hear an explosion on-screen sound like it’s coming directly from the explosion—or the sound of an on-screen kiss coming from two pairs of lips for those not into action films.

The end result from all of these leaps in TV technology—on a visual, audio, smart and even aesthetic viewpoint is a far more immersive and satisfying viewing experience, and just another reason why today’s TVs represent a quantum leap in entertainment value.
