Last month, Exeger and Mayht announced a partnership to create a portable Bluetooth speaker that's powered by light. At CES, they offered a glimpse at the prototype.
Swedish company Exeger makes Powerfoyle, a material that can turn natural and ambient light into power. Dutch startup Mayht, meanwhile, is behind a type of audio tech called Heartmotion. It claims to have reinvented "the core of the speaker driver" to allow for speakers that can be more than 10 times more compact than other models without sacrificing sound quality or bass output. According to TechCrunch, Mayht's drivers need less energy than similar audio devices, so solar cells are a seemingly sufficient power source for the speaker.
Details about the speaker's specs remain unclear, such as what percentage of the device's surface is covered in Powerfoyle material. We've seen some headphones that use this tech, including Urbanista’s Los Angeles headphones. Based on our time with those, the speaker will need a decent proportion of solar cells to meet Exeger and Mayht's claim that it has "unlimited battery life" — at least if you don't live in eternal darkness.
Whether the speaker can deliver solid sound quality remains to be seen. The physical size of a driver and the depth of a cabinet are key factors in how speakers generate bass, so it'll be intriguing to hear how Mayht compensates for that.
