Cynaps Bone Conduction Headset Teardown

[@scramble45]

Her handle is from Ada Lovelace (see wiki), I believe. But really only she would know.

[@IraQNid]

I'd love to see teardowns of the Brother ScanNCut DX digital cutters. In particular the 125, 230, and newer models. It would be cool to see what types of computers, RAM, and upgrade/hack options there might be inside.

Lady Ada, she did undergrad and masters from MIT

These kinds of transducers are really sub-optimal for the application. As Limor pointed out, they really take a lot of current to operate, which makes poor use of the energy from the LiPo cell. A better technology would be ElectroActive Polymer (EAP) actuators. They, instead, use relatively high-voltage and low-current to modulate sound into an adjacent object with very high resolution and can pulse from sub-1 Hz all the way to ultrasound at surprising dynamic range. I believe the technology is already being implemented by Bayer Chemical as a haptic device, but it could be so much more.

Ahg i have not tested these headset (but my tooth aces less now after this video) lovely

Hi, thanks for this video, it was very useful. Could you say what would be the smallest possible battery (size and power) able to work with this bone conduction transducer ? Regards, Benjy

[@CollinLim]

I get 130 minutes of continuous runtime from my set-up: bone conductor transducer, DFPlayer Mini, LiPo charger module, and a five-year-old 100mAh 1S 20C LiPo battery (20 x 14 x 7mm).

Poop scares me a LOT. Brown gloop coming out of your body, how can that be safe?

[@smithincanton]

I'm going to guess it would be she took her name from Ada Lovelace, a 19th century mathematician and writer credited as one of the first computer programmers.

[@LizQuilty]

I'm only hearing the music background and no speaking - is that just me?

[@lanceseidman]

Those sets scare me, a LOT. Vibration to the skull, how safe can this be?

[@AshenTechDotCom]

very, in many cases more so then actual on or in ear drivers, mostly because, most of the bone conduction stuff enlarge, dosnt have the driving power behind it to push dangerous volumes, use to work for a place that made hearing devices that used bone conduction, and required a belt mounted power pack that either had 2x9v or 8xAA cells in it, far from optimal but they allowed people who couldnt hear due to illness or damage, but whos inner ear was actually capable of hearing and transmitting sound to the brain. i also know a fellow who was part of a test group in the military for implanted mic/speaker setups, it was originally just going to be a way to more securely attach a headset onto a soldier, the implanted component he has at this time, is not a speaker or actuator or whatever its just a magnetic mount system thats under the skin imbeaded in is skull, also, they didnt take people who where not already going in to surgery for other reasons into that test, and everybody agreed to be a subject at the time, in his case, the hearing he lost a large % of when he was injured becomes a non-issue, the bone conduction setup hes got now can actually be put into a few different modes, one, just fills in the parts of his hearing that is weak or ineffective when doing day to day life tasks, or it can do full spectrum, or vocal only, and with the current unit, it can also be put into a training mode to learn somebodies voice, and freq shift it, if needed, to be more easily understood by him, only one of his ears is damaged this way, and hes still got about 50-60% hearing in that ear, just large range that nolonger functions without the bone conduction unit, his wife is hard to hear/understand most of the time for alot of people, myself included, his unit... shifts her voice in that ear, such that... using his unit connected to a set of over ear bone conduction headphones he has...even i can understand her flawlessly... and normally i have to remind her to speak up and speak clearly... (i love her, shes genuinely one of the best people you could hope to meet, but, shes a tiny asian woman, who is embarassed by her accent and talks very quiet, outside when shes around people who speak her native lang, then shes stupidly loud....) this stuff is actually really cool, my buddy is quite lucky to be in the program, and the VA still many years later, upgrade him and have even when he had ear surgery, replaced the mount unit with a much newer, much more "long term safe" version, though, his old one showed no signs of corrosion like some apparently had, the new unit will also allow something the company is working on, that will be part of the transducer once the company has that part of the unit ready for more wide testing, it will be powered/driven by the external magnetized assembly, also the new units exteral parts more closely resemble the coclear implant setup, in part because they can use the same shells and such, its very cool tech...

[@NilesBlackX]

Have you ever spoken? You're vibrating your skull the same amount. This is why your voice sounds different on recordings. It's literally the same. If you're going to be paranoid, worry about the magnets, although all headphones use magnets so...?

[@gudenau]

Why is ladyada called ladyada?

[@angiripli2456]

Nice

[@LizQuilty]

nope, it was just me, darned headphone wire was broken!

[@planecrazyish]

👏👏👏👏👏👏👏👏👏👏👏👏👏

[@gudenau]

Make sense.

[@EasyDYITech]

Looks like something right out of a Tom Clancy book. something like this would be great for getting commands in black op missions without giving away your position. It almost makes me wonder if such a technology can be coupled with a magnetized metal plate to extend the plates magnetic lines along side sound waves give It more magnetic range. make a minni tractor beam of sorts or repulser tech . or a device that can effect or bend light. Maybe not in my life time but I have to say awesome tech. Thanks for the tear down.

[@NilesBlackX]

I like your optimism about making a "device that can bend light"

[@jeremy0203]

Could have made the hat not so ugly

[@kglefo]

> Why is ladyada called ladyada? Because "Rumplestiltskin" was already taken. :-)

My one comment is Signal-to-Noise ratio. Please cut out the annoying elevator-music background and just concentrate on describing what you are working on.
