This is a passive amplifier manufactured with 3D printing in ceramic and designed for iPhone. The acoustic designed chamber amplifies the sound emitted from an iPhone speaker without the need of extra power supply.
The product is seamlessly printed in ceramic, with structure embedded inside, to create a smooth sound tube. The 3D printing technology also helps the designer to minimize the product size by folding up the sound tube. It makes this product as effective as some passive amplifier twice the length.
Made for iPhone 5c, 5s, 5, 4s, 4 with or without iPhone Case.
Dock opening: 17mm x 64mm
