HiWave in Cambridge is showing new loudspeaker driver and amplifier designs in its “Tempus” demonstrator at Consumer Electronics Show (CES) this week and the ALMA (The International Loudspeaker Association) Symposium using technology developed in Bristol.

Tempus brings together an all-new variant of the company’s BMR (Balanced Mode Radiator) speaker drive unit and its Audium amplifier chip, originally developed and designed in Bristol, in a reference design that now delivers higher power output plus Bluetooth wireless audio streaming.

The Tempus transparent enclosure enables engineers to see the simplicity of the structure that encapsulates the BMR drive unit and the electronics module based on HiWave’s Audium amplifier chip. The single Lithium-ion battery that powers the device is also visible. Pairing the speakers with any Bluetooth enabled phone or tablet produces a clarity, range and depth of sound that belies the 23cm tall unit’s physical size. At typical listening levels the battery powers the unit for over 30 hours between charges.

“Our BMR technology overcomes the difficulties and compromises that come with the use of conical or domed diaphragms,” said Chris Travis, CTO of HiWave.” 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”.

Immediately following CES, HiWave has a display booth at the ALMA (The International Loudspeaker Association) Winter Symposium at the Riviera Hotel in Las Vegas on 13th and 14th January. ALMA has titled the symposium “The Future of Loudspeakers” and HiWave will be showing industry specialists the key benefits of its low-cost, full-range, wide-dispersion BMR speaker drive units coupled with the power-saving, battery life-enhancing Audium amplifier chips.

“With consumers’ focus on value-for-money we are creating components that punch well above their weight in terms of cost-effective audio performance,” said James Lewis, CEO of HiWave.
