Balanced Armature Drivers Offer Premium Sound for Earphones
by 
Qualcomm Inc. announced that its subsidiary, Qualcomm Technologies, International, Ltd., has added active noise cancelling (ANC) to its CSR8675 product platform, claiming the industry’s first Bluetooth audio system-on-chip (SoC) to integrate this advanced technology. The new feature reduces the complexity and cost of adding active noise cancelling to headphones by eliminating the need for a separate ANC chip, which delivers premium audio experiences in much smaller form factor designs including ultra-small earbuds and headphones, said Qualcomm.
The CSR8675 is a fully integrated Flash platform with an embedded 120 MHz, 24-bit DSP. The device supports Qualcomm aptX and Qualcomm aptX HD audio technologies.
"Demand for stereo wireless in-ear devices and headsets is growing rapidly. Users want to enjoy a superb audio experience in any environment, without sacrificing quality when they listen to their music, videos and games," said Anthony Murray, senior vice president and general manager, IoT, Qualcomm Technologies International, Ltd., in a statement. "Being the first to bring a Bluetooth audio SoC with integrated active noise cancelling technology allows us to work with manufacturers to integrate noise cancelling technology into a wider range of their products now, while consumers, who have experienced noise cancelling in high end headsets, are increasingly wanting this capability in their more casual audio headsets which typically retail at lower price points."
