Flat panel speakers are nothing new. Dayton Audio (https://www.daytonaudio.com/topic/excitersbuyerguide) sell exciters you can put on any surface to make it into a loudspeaker. The sound quality highly depend on the material you put it on. As a general rule, do not expect high quality sound unless the material is optimal. There are several videos on Youtube which demonstrate them. A great one here: https://www.youtube.com/watch?v=XC814uQjlaE&t=1562s&ab_channel=AmplifyDIY
The news from LG is that they apparently have designed a new type of exciter. Do not expect miracles.

Think forward. Speakers complicate aerodynamics, sound proofing, and add weight where you do not want weight. Cars are just drones that don’t know how to fly yet. We’ll all want to be wrapped in the most aerodynamic space and weight conscious vehicles possible, because it’s going to be a balance between comfort, range, and economics.

timg528 t1_iy38aro wrote
Weight is the only valid argument here, and even then you're talking a miniscule fraction of the total vehicle's weight. As long as crumple zones are mandated, there will always be room for speakers (think between the outer and inner panels of doors. Soundproofing is more for road/vehicle noise and will tend to be on the outer panel of any body section.

FallofftheMap t1_iy38oym wrote
I couldn’t disagree more. Weight and space required for things like speakers complicate an engineer’s job, requiring compromises. Crumple zones require empty space to crumple. They don’t work properly if they smash a speaker into your kneecap. There are huge advantages to minimizing the space required by the most space wasteful components of vehicles, and speakers are obvious low hanging fruit.

timg528 t1_iy3a7bs wrote
A speaker is an insignificant intrusion into a crumple zone and no engineer cares about a speaker going into your knee. Speakers themselves are already pretty thin to the point where if it's going to happen, you've got larger issues based on the fact that a 6.5" speaker is around 2.5" deep, held together by paper, and weighs around 2lb.
As for weight, these will save at most 35lbs (assuming a heavy set of speakers at 50lbs total and the fact that these are only 70% lighter) on a 2000-6000lb vehicle.
If anything, these would get put into flat panel TVs, but a car? There's too much dead space behind nearly every panel to justify it.
Finally, keep in mind, we've had flat panel speakers for decades, and this isn't the first article to proclaim their use in cars.

Except speakers are smaller than the empty space already required to exist in cars.
You have to have front crumple zones and side windows that go up and down. That leaves empty space which is filled by speakers. Switching to a smaller speaker doesn't change the space required for a door window. (Because the door window doesn't and can't fill the entire door frame when lowered.)
The front crumple zones leaves space under the windshield in the dashboard. This is unused space that can't be filled with anything massive. But speakers are mostly thin metal and paper. So they can go into crumple zones where nothing else can.
A smaller speaker means more empty space inside the frame. It can't save space.

If I'm understanding these speakers correctly this is just old tech being rehyped under a new brand. They're basically normal speakers but replace the "black circle paper resonator disc"(idk it's real name) with a suction cup. And now you can stick it to any surface and just resonate that be to make your sound... it sounds like absolute shit on %95 of surfaces. It turns out most objects have very clear resonating frequencies and every time the speaker would play those It would be much louder making it sound very tinny.
I could definitely see a company adding a microcontroller and microphone to try and real time create an equalizer to mitigate this, and it might work and might be what was done here.
Also there is a YouTube channel called tech ingredients. The main guy like to talk long and dry but he gives out good info. He did a video where he took super cheap resinator speaks and tested a bunch of different materials and shapes of what to stick it to for the best inexpensive sound. Resulting in an amazing tutorial on how to make loud diy very high-fi speakers for about 30$

Bass and low frequency sound are enhanced greatly when using larger panels or increased areas of substrate. Additionally, using a heavier substrate will allow deeper bass to be achieved, but at the expense of reduced treble output."

People were listening to low-quality audio all the time before things went digital. The radio was the most popular way to listen to music for a very long time and it was not high quality until relatively recently. There was vinyl for a while, but many people just bought cheap turntables and didn't see a need to spend the money for a quality one. Audio cassettes were far from lossless, and people would put them into cheap stereos or they used cheap headphones. Cheap headphones have been used for many decades.
My point is that the general public has never really cared about audio quality, and the people who do care have always had ways to hear quality sound. I don't think that has changed at all (or if anything, quality has become cheaper to achieve, so more people can afford it).

You know what we had before Bluetooth and streaming?
- Cassette players
- Shitty plastic walkman headphones
- AM/FM radios
- Scratched records
- FM transmitters for your car
- Tiny desktop speakers bundled with a computer
- Laptop speakers
- Low quality burned CDs
High quality listening is cheaper and more accessible than it's ever been. Listening to Spotify over bluetooth on a stock car stereo is far better than the radio ever was, and that's without even getting into the convenience factor.
The truth is that people have never cared at large about audiophile level quality. The only difference now is that the baseline will get you far enough for most listeners, while you used to have to take some amount of effort to get to that level.

MyNameIsRay t1_iy3umt4 wrote
Haven't heard these in particular, but I have used a bunch of transducers that turn solid panels into speakers (Clark Synthesis/Aurasound/multiple Dayton transducers, and the bass-specific IBeams and Buttkickers), and they all have the same issue.
The material you stick it to has it's own absorption/reflection/resonance properties, which become audible when you use it as a speaker. You can easily tell if it's attached to metal, plastic, wood, or glass. It doesn't sound "like the panel is a speaker", it sounds like "a speaker behind the panel".
For bass, thicker/stiffer materials (or those with less surface area) need more power, which means it effectively reduces the output when used with the same power. Same transducer, same signal, will have wildly different response curves if attached to a side window vs a rear window, or a window vs the dashboard.)
For highs, basically everything absorbs high frequency sound (that's why you tend to only hear low frequency bass outside a loud car or club). No matter what, the high end is neutered, they all lack the "sparkle".
Tyler_Zoro t1_iy3uy9k wrote
It's not the pitch that is the concern, so much as the "shape" of the sound.
Panels can be turned into incredibly good speakers (example) but that's when they are flat. The surfaces in a car are going to created much more complex wave-fronts because they aren't flat.
I presume that what LG is showing off is some sort of system that compensates for this. I wouldn't be perfect, but it could potentially be good enough to improve on the speakers you can otherwise get in cars.
Of course, 17 year olds will use it to vibrate the rivets out of their cars because that's what they do.

There’s hopefully some feedback mechanisms for tuning the signal for better fidelity and giving some tips to users for better frequency response options. Hell, a calibration system that guides users to put the transducers on different surfaces and places would be pretty neat if you ask me. Something on the floor of a car or the dash would work better for sound than windows, especially because rolling the windows down would mean no more speakers.

Bass requires surface area and excursion (in and out movement) to be reproduced with volume. You can eq to make it more pronounced in comparison to the other frequencies, but you are still limited by the speakers physical characteristics for how low and loud they can play. Judging by the picture,these could maybe play down to 250-200 hz with good output. That's low enough to be a good midrange speaker, but it will still need a woofer to cover bass(20-80hz) and midbass(80-250hz). The good thing about speakers like this is that it allows for an engineer to design a speaker system with very good imagining. They can place these in spots in the vehicle where the sound should actually be coming from. With DSP(digital sound processing) they will be able to place these in a way that lets a car sound like it has a very wide soundstage. Doors for the widest sounds, the widest parts of the dash for most left and right content,and in the center of the dash for center stage content. Bass frequencies aren't as directional as the frequencies these will play so woofers in the doors or inside the bottom of the dash will sound convincing still. Sorry for the text wall, sometimes I get a little too nerdy about audio. Also, I'm going by the picture, didn't read the article. Edit: skimmed the article, what I said seems to be spot on. I would love to see a response graph for these.
TL/DR; They won't produce much bass, but they will allow for accurate sound placement in the frequencies that count for directionality.

The frequency response of typical transducer/actuator speakers, as I’m familiar calling them, rely heavily on the material they are mounted to. The EQ can be tuned to account for this, but a good one should have high fidelity down past 200 Hz. That may not be low enough for some people but I only stop there as I haven’t actually seen the data below 200 Hz.
I can’t yet find the specs for the LG TASS, but once they’re available I’d compare to the linked transducer below, which has wonderful fidelity.

The worst is when a game has really high quality chatter as ambient noise. So many times I’ve taken off my headphones and looked around because I swore I could hear someone right behind me.

I’m not going to dig into it for Sony but will add that phase usually does this. If you have one speaker in phase and one out of phase on the opposite side the sound “comes from everywhere” which is undesirable when it comes to setting a front sound stage.
I’d imagine if you those Sony units use multiple drivers that could switch phase live by driver it could use it in cool ways.
Totally bullshitting here though

I am optimistic that the technology has advanced leaps and bounds. Esp if a giant like LG is involved.

There are still limitations because of basic physics. You’re going to need to be able to move a lot of air to get any decent amount of bass.

I mean, when I got in the beta, and turned it on, it was radically different. The software was very much doing something, and I wasnt in a different room.

Science evolves. It always works with the limitations of known sciences from a particular frame of time, but it evolves.
They thought Newton was the end all be all until Albert Einstein came. My point is technological advancement, limitation is the first barrier that is broken during advancements.

The basic physics of how sound works doesn’t change. To get loud bass notes, you need to be able to vibrate a lot of air. What technological advancements have broken fundamental concepts in physics?

Lol you’re stubborn aren’t you. This particular TASS(Thin Actuator Sound System) produces sound by vibrating off the panel/surface it is attached to. Look up the word innovation.

Not surround sound systems though. At least not the ones I drive. Hearing speakers that are mixed and balanced but still playing the whole audio track is one thing. Hearing isolated sounds from the rear speakers would be something else entirely.

You're arguing points that relate to the size of the speakers while disregarding the same points to contradict yourself

buffalohands t1_iy6y4os wrote
Ok, i might be able to help with this. I'm an artists and I discovered the existence of this technology a few years ago. I wanted to make some art Installation with it and started experimenting.
The problem is: in a speaker, the vibration (just like what tass would produce) is basically just already "stuck" to the perfectly shaped and perfectly resonating surface ... And that's what we call a speaker. The perfect shape for sound into air is somewhat like a cone... Think megaphones etc. We all learn this as kids when screaming into various tubes and stuff. The perfect surface to resonate would be something thin and flexible but also not to thin because then it just wobbles away. So that's why you have these cone shaped cardboard things in your speaker. A speaker is basically a TASS that comes with its own built in perfect resonating surface.
You can of course improve this technology a bit with as was mentioned buit in equalizers to make up for "sub perfect" resonating surfaces that are too rigid or not cone shaped at all. But the principle will remain the same. There is nothing one can improve about how sound is transported through air. It's just how it works. And yes you can use almost any surface to vibrate it and it will transport these vibrations into the air. Just like you can hear loud music outside of a car. The whole care becomes the resonating surface that vibrates the air around you to reach your ears.
But all the comments that say: yeah it works but it sound funky are correct. Because any surface that is not cone shaped and not of a flexible yet rigid enough material will sound less nice as what we have in speakers.
The basic idea of an actuator is very old. Is a bit how old gramophones created their sound. The fact that we still went through all the trouble of inventing the speaker still speaks for itself.
Edit: some spelling (I'm on mobile sorry for format)

It’s all time and phase based, in addition to multiple drivers that are individually controllable.
If you are interested in it - look into Klang in-ear monitoring; it’s designed for live music but can be used for all kinds of things.

timg528 t1_iy8epam wrote
Yes, but your first message indicated you have issues with reading, which is why I want to know what specific statement you are misreading this time.
My overall point was that if you were to replace 50lbs of traditional speakers with these new flat ones, you'd only save 35lbs, which is miniscule compared to the overall vehicle weight.
If you assume 20lbs of speakers replaced, it's even less weight saved.

Think forward. Speakers complicate aerodynamics, sound proofing, and add weight where you do not want weight. Cars are just drones that don’t know how to fly yet. We’ll all want to be wrapped in the most aerodynamic space and weight conscious vehicles possible, because it’s going to be a balance between comfort, range, and economics.
Weight is the only valid argument here, and even then you're talking a miniscule fraction of the total vehicle's weight. As long as crumple zones are mandated, there will always be room for speakers (think between the outer and inner panels of doors. Soundproofing is more for road/vehicle noise and will tend to be on the outer panel of any body section.
I couldn’t disagree more. Weight and space required for things like speakers complicate an engineer’s job, requiring compromises. Crumple zones require empty space to crumple. They don’t work properly if they smash a speaker into your kneecap. There are huge advantages to minimizing the space required by the most space wasteful components of vehicles, and speakers are obvious low hanging fruit
A speaker is an insignificant intrusion into a crumple zone and no engineer cares about a speaker going into your knee. Speakers themselves are already pretty thin to the point where if it's going to happen, you've got larger issues based on the fact that a 6.5" speaker is around 2.5" deep, held together by paper, and weighs around 2lb.
As for weight, these will save at most 35lbs (assuming a heavy set of speakers at 50lbs total and the fact that these are only 70% lighter) on a 2000-6000lb vehicle.
If anything, these would get put into flat panel TVs, but a car? There's too much dead space behind nearly every panel to justify it.
Finally, keep in mind, we've had flat panel speakers for decades, and this isn't the first article to proclaim their use in cars.
Like I needed to waste my time doing this.
