A passive amplifier system has been developed which improves the sound and the volume of a smartphone enormously, without complicated technology. The entire body consists of porcelain. The "transmission line" achieves in combination with the gallant material porcelain incredible sonic results. The glazed surface and shape analogy toward a metronome, gives TOCTOC the high quality appearance. The amplifier system provides easy handling and can be used everywhere by everyone.
