HiWave Technologies has announced the immediate availability of a wireless speaker module for consumer Hi-Fi applications that delivers over four months of playback from a single battery charge. It will be on display for the first time at CES 2012.
The 13W burst (26W peak) module enables OEMs to more rapidly create speakers that receive streamed audio from home cinema systems, PCs, smartphones and tablets throughout the home, without any trailing speaker and power cables.
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 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 of playback – and over 145 hours of playback from a rechargeable size D battery (11,000mAh).
Commenting James Lewis, CEO of HiWave said: “Wireless speakers enable a user to more easily stream music throughout the home and let people position them to achieve either the best sound quality or the best aesthetics. The demand for such technology has increased as we store music on, or stream cloud-based music to, PCs and smartphones,”
“And, whilst it’s been possible to transmit music wirelessly for many years; amplifier chips had been too inefficient to ditch the power cable.”
The amplifier module works with all speaker types, including HiWave’s BMR flat panel drivers. By also integrating HiWave’s flat panel BMR speakers, manufacturers can deliver a wide audio frequency range with a greater fidelity, and eliminate the need for a separate tweeter.
HiWave anticipates consumer Hi-Fi quality speakers to be available early 2012.
