Wolfson audio technology selected by Lenovo for flagship smartphone

Wolfson Microelectronics has announced that its WM5102 High Definition (HD) Audio System-on-a-Chip (SoC), and its WM2000 earpiece driver with its ambient noise cancellation (ANC) technology built-in, has been selected by Lenovo for its latest flagship smartphone, the IdeaPhone K900.

The WM5102 HD Audio SoC with voice processor DSP, combined with the WM2000 earpiece driver with ANC, has been designed to help smartphone manufacturers deliver a clearer, more natural-sounding voice call, even in the noisiest environments. Featuring integrated transmit-path (Tx) noise reduction, echo cancellation and receive-path (Rx) noise reduction, the WM5102 enables intelligible, natural-sounding conversation and reduces background noise transmitted via voice calls by up to 90%, regardless of whether the caller is travelling through a busy train station, socialising in a bar or relaxing at home.

Providing 113dB signal-to-noise ratio (SNR) and low power, high performance audio DSP, the WM5102 offers a HD Audio experience but with minimal power consumption which OEMs can use across all smartphone application processor platforms.

The WM2000 low power, high quality earpiece driver, with Wolfson’s Rx ANC technology built-in, uses a feed-forward system to provide up to 20dB of noise cancellation during a call, enabling users to hear what is being said in noisy environments, and resulting in less chance of calls being terminated as a result of background noise which can make communication difficult.

The Lenovo IdeaPhone K900 runs on an IntelAtom processor, and will be available in China, the world’s largest smartphone market, imminently and then in other selected markets.

John Forsyth, VP Product Management, Audio Solutions at Wolfson, said: “Consumers are increasingly demanding a better audio experiences from their smartphones in even the noisiest environments, and we are pleased to work with Lenovo to help deliver audio to their flagship smartphone. Lenovo selecting our audio solutions for the IdeaPhone K900 is testament to our technology and expertise in providing differentiated audio experiences to many of the world’s leading consumer electronics applications.”
