 Earbud reference design supports Qualcomm Snapdragon sound
Goertek has unveiled a powerful new earbud reference design to help manufacturers looking to implement Qualcomm® Snapdragon Sound™ technology to speed their time to commercialization.

Goertek collaborated closely with Qualcomm Technologies International in the optimization, system integration, acoustic optimization, and manufacturing of the Rox earbud reference design. Powered by the Qualcomm® QCC5141 Bluetooth Audio SoC, the Rox reference design is optimized for use in earbuds and hearables and is designed to deliver high-resolution music, crystal-clear voice calls, and lag-free gaming— with superior connectivity and extended battery life.

Each side of Rox reference design has three Goertek high SNR MIC and one SBS (Super Balance Speaker) speaker to support high performance ANC and deliver a premium wireless sound experience. Goertek has collaborated with Qualcomm Technologies on the Rox reference design which is engineered to meet the strict metrics for latency, voice call quality, music quality and connectivity required to carry the Snapdragon Sound logo. Key features of the Rox reference design include Qualcomm® aptX™ Adaptive audio technology for 24-bit 96 kHz music quality, aptX Voice for 32 kHz super wideband voice quality and always on wake word detection for Amazon Alexa or Google Voice Assistant. In addition to this Goertek could also offer ANC and EQ tuning to help OEMs reduce development time and cost. The device is optimized for power with 6.1 mA current during ANC to support 5 hours of battery life with 35 mAh battery.

Justin Zhan, GM of Goertek Consumer Electronic Products, said, "Goertek has developed several generations of reference designs based on the Qualcomm® Snapdragon™ Platform and we are excited to extend that to Snapdragon Sound which is designed to provide seamless, immersive audio in, and across, devices including smartphones, wireless earbuds and headsets. Goertek's capability is demonstrated with this, the first true wireless earbud reference design with support for Snapdragon Sound technology which we have designed with human wear comfort and a superior sound experience for listening to music, communicating on the phone, or wirelessly gaming.”
