Waterproof phones are few and far between stateside, but in Japan, they're pretty common -- and hey, who wouldn't like to be able to safely take that two-hour conference call from the comfort of your bubble bath? To that end, Murata is touting its new ultra-thin piezoelectric speaker that clocks in at just 0.9mm thick while maintaining IPX7 compliance for water resistance. It's said that waterproof phones are traditionally made by covering speaker holes with a film, compromising sound quality -- but with Murata's design, no film is necessary, offering you that symphony hall-style audio you so desperately need from sixteen inches under the surface of your swirling hot tub.
