- Black Copper Mini Boom Speaker is a product of Black Copper Technology Co. Ltd is a high-tech enterprise founded in 2003. An unusual design by HiWave Technologies, the DyadUSB USB-powered stereo audio amplifier module used in the SoundScience QSB 30W Portable USB Speakers allows a USB-powered and driven stereo speaker pair to supply 30W of power for short periods with a signal that has short high-power peaks and much lower average power, as most music and speech does. It stores energy from the USB connection during quieter periods, delivering high power for the peaks. (With a constant sine-wave input, power output cannot exceed the 2.5W that any USB speaker can deliver). The module is claimed to require less power most of the time, increasing laptop computer battery endurance, and delivering clean, unclipped sound peaks.
