CES 2012: UK firm demos novel drive units and amplifier technology

According to the Cambridge based electronic circuit specialist, the Tempus brings together an all new variant of its Balanced Mode Radiator (BMR) speaker drive unit and its Audium amplifier chip. The reference design says HiWave, delivers higher power output plus Bluetooth wireless audio streaming. Housed in a transparent enclosure, by pairing the speakers with any Bluetooth enabled phone or tablet, the Tempus is designed to deliver clarity, range and depth of sound. At typical listening levels, the battery powers the unit for more than 30h between charges. Chris Travis, cto of HiWave, said: "Our BMR technology overcomes the difficulties and compromises that come with the use of conical or domed diaphragms. The flat diaphragm's bending modes give these drive units wide dispersion across the full frequency range, approximating the performance of an ideal point source. By using HiWave drive units our customers are creating better sounding products in shorter timeframes than ever before. The Tempus demonstrator shows speaker design at its purest - a flat drive unit in an enclosure that is all curves, giving it superior acoustic and mechanical properties."
