For TrueWireless Earbuds
QUALCOMM recently launched their next generation of ultra-low-power Bluetooth Systems on a Chip (SoCs), designed to deliver outstanding truly wireless support with innovative QUALCOMM TrueWireless™ Mirroring technology. Optimized for use in true wireless earbuds and hearables, the QUALCOMM® QCC514X (premium tier) and QUALCOMM® QCC304X (entry/mid-tier) SoCs provide customers with improved robustness and connectivity, increased battery life, integrated dedicated hardware for Hybrid Qualcomm® Active Noise Cancellation (Hybrid ANC), Voice Assistant support and premium wireless sound and voice quality.
Innovative TrueWireless Mirroring Technology
These new SoCs build on the proven technology of the earlier launched QCC5100 and QCC30xx series. One key added feature is that these new solutions now support the innovative QUALCOMM TrueWireless Mirroring technology. With this technology, one earbud is wirelessly connected to the phone via Bluetooth while the other bud mirrors the connected bud and is engineered to deliver a rapid swap under several scenarios. There is also a unique connection made between the buds such that is the mirroring bud misses a packet in the transmission, it can request that from the connected bud and by this greatly improve the robustness of the TrueWireless experience.
For example, if the user removes the connected bud from their ear, the mirroring bud is designed to take over the connection to the phone, to avoid any interruption of streaming music or an active voice call with no action required by the user. QUALCOMM TrueWireless Mirroring is also engineered to manage a single Bluetooth address so only one “device” shows up when the user is pairing their earbuds to a phone.
Integrated Hybrid ANC technology
The new SoCs also boast integrated Hybrid ANC technology. The dedicated ANC hardware integrated in the SoC enables super-low latency leak-through of the outside environment to allow for truly natural awareness of the surroundings, making ANC not just for airplane use, but applications in sports, office environments and other places throughout the user’s day.
With up to 13 hours’ playtime
The QCC514x and QCC304x SoCs are also optimized to deliver leading power consumption under various use cases, with up to 13 hours’ playtime based on 65mAh battery, depending on settings and other factors. Now, with ANC enabled, there is minimal impact on battery life, allowing consumers extended battery life for enjoying sound on international flights or long periods at the office. Additionally, the extended playtime on the device allows for the shrinking of the battery used in the charging case and a more compact design that readily fits in a pocket.
Premium tier QUALCOMM® QCC5141
At the premium tier, the QCC5141 offers dedicated support for Always on Voice (wake-word) activation for multiple voice ecosystems. For entry/mid-tiers, the QCC304x family offers push-button voice activation for multiple voice ecosystems, enabling OEMs to add voice assistant capability more quickly and cost effectively. By adding this support to entry/mid-tier SoCs, QUALCOMM is helping OEMs bring voice assistant capability to lower cost segments for the first time on single chip solutions, making it possible for voice to become a more widely pervasive feature across a greater range of price points.
