Wireless speaker module delivers 40 hours playback from a single AA
Cambridge, UK-based HiWave has unveiled a wireless speaker module for consumer Hi-Fi applications that delivers over four months of playback from a single battery charge. The module uses HiWave’s HIAS2001-QNC-010 amplifier chip, which consumes one-20th the power of other amplifier technologies at typical listening levels (68dBC at 1m).
The 13W burst (26W peak) module enables speakers to receive streamed audio from home cinema systems, PCs, smartphones and tablets. The complete wireless speaker system draws less than 75 milliamps at typical playback levels. Connected to single 1.2V rechargeable NiMH AA battery (3,000mAh) the speaker delivers 40 hours (600 songs, 220 albums) of playback – and over 145 hours of playback from a rechargeable size D battery (11,000mAh).
