At typical listening levels the system, called Dyad BA3, consumes an average of less than 300mW, yet also accurately reproduces the audio peaks.
The system combines HiWave’s proprietary wide range loudspeaker technology, BMR, with HiAS2002 ultra efficient amplifier chip and CSR’s BC05-MM Bluetooth module. OEMs adopting the design would be able to deliver wireless, Hi-Fi quality loudspeaker products to the market in less than 3 months.
Commenting James Lewis, CEO of HiWave said, “Bluetooth is an ideal technology for wireless speakers, especially as we shift to storing music in the cloud. It has both lossless and ultra-low power consumption variants, giving both quality and long battery life, and has been designed into almost every phone and laptop over the decade.”
The Dyad BA3 is the third design in HiWave’s series of reference platforms based on its BMR speaker drivers and ultra efficient wireless amplifier ICs. These speed time to market for HiWave’s customers, and its first reference platform, Dyad USB, was adopted and taken to market just months after its launch.
Schematics and design notes for the DyadBA3 reference design are available under NDA via HiWave or one of its local sales channels.
