Tiny ‘hearing’ device is 100,000 times thinner than your eardrum
Finding long-range, low-powered sensors for wearable devices is the next scientific frontier. Researchers at Case Western Reserve University are working on atomically thin transducer "drumheads" that can send and receive signals at radio frequencies even greater than those we can hear with our natural ear. Better yet, the drumhead is 10,000,000,000,000 times smaller in volume and 100,000 times thinner than the human eardrum and can detect a much wider range of signal than other similar devices.
Wireless ButtKicker kit ready to rumble your posterior
Earlier this year, we were fortunate (or unfortunate, depending on perspective) enough to get our rumps on one of the famed ButtKickers. For those unaware, these devices are meant for installation underneath a seat or sofa in order to provide chair-rumbling effects to help you "feel" the film. Now, the Guitammer Company is making them even easier to install by cutting the wires, bringing low frequency audio transducers just inches from your derriere without any cords necessary. The above pictured kit will go on sale next Friday (yes, that's Black Friday for you Americans) for under $300 on Amazon -- are you really ready to rumble?
Tymphany's LAT250 subwoofer: smaller than you'd think
Believe it or not, that thing you see above actually is a subwoofer, albeit a wee one. Tymphany's LAT250 (Linear Array Transducer) deviates from the traditional cone approach and instead "displaces air using a linear array of multiple smaller diaphragms." A pair of internal motors drive both sets of diaphragms, and the unit itself can be mounted either horizontally or vertically depending on your install needs. Most notably, this thing reportedly checks in at just 10.24- x 3.5-inches in size and weighs only 1.86-pounds, but it can somehow still handle 100-watts RMS. As you'd expect, Tymphany is aiming this unit at users with tight space requirements, and while a variety of impedance configurations are available, the standard 4-ohm dual-coil version is available now for $58.[Via AudioJunkies]Read - MadiSoundRead - Tymphany
Bose patent app sees electroacoustical transducers in our chairs
While finding hidden speakers tucked neatly away in one's headrest, rocking chair, or gaming seat isn't exactly surprising, Bose is hoping to integrate the technology one step further by getting "surround sound" into practically every seat imaginable. According to a patent application filed by the company, it's hoping to develop an audio system that includes an "electroacoustical transducer mounted in the back of a seat" so that surround sound is radiated and focused around the ears of the listener. Obviously, said technology could be placed into cars, recliners, office chairs, and beach loungers with relative ease, and while musical entertainment is clearly the primary candidate for use in such a system, the filing also mentions possible telephone integration. Unsurprisingly, Bose didn't mention any details surrounding RMS ratings, frequency ranges, or driver sizes.[Via Wired]
MTI Whirlpools' Stereo H2O throws tunes in the tub
We know, you're already skeptical about this one, especially considering all the dodgy material that's already floated your way, but unless someone at MTI Whirlpools is blowing hot steam, this one is for realz. The Stereo H20 bathtub actually does manage to integrate audio-blastin' equipment into a container full of water without guaranteeing any sort of unexpected electrocution along the way. Touting the soothing benefits of "full-bodied sound," the tub rocks several acoustic transducers on the shell's exterior near the waterline, which should theoretically create a bucket of sound to "envelope" the bather in question. Additionally, the digital amplifier that powers said speakers includes provisions for your iPod (or any other DAP, we presume), CD / DVD player, or even an eight-track jam if you can find the correct adapter. Unsurprisingly, there's no word yet concerning the pricetag on this unique piece, but if it's anything like the musically inclined Aquagate shower, it'll probably be reserved for the more affluent set anyway.[Via OhGizmo]
