Leading high-performance analog IC and sensor supplier ams (Ams, SIX stock code: AMS) today announced that the earphones of Huawei ’s latest smartphones will use the ams speaker driver AS3415 with active noise reduction (ANC) to help enhance the headphones Noise reduction effect. The headphone of Huawei's new high-end Android smartphone Ascend Mate 7 uses the ANC chip of ams. The passive noise reduction of the earbuds, combined with the active noise reduction function, can reduce most of the low-frequency environmental noise below 3kHz. This function eliminates external noise interference and brings a realistic listening experience. Ascend Mate 7 enables users to easily enjoy music or hear sound content. The traditional method used by traditional earphone users is to turn up the volume very high to resist environmental noise. This method improves the signal-to-noise ratio, but may damage the sensitive inner ear. If you use Ascend Mate 7 headphones, due to its own noise reduction function, users can easily listen to every sound at a suitable volume. The AS3415 with high-performance active noise reduction also brings a more pleasant voice call experience to Ascend Mate 7: some consumers often struggle to understand each other ’s speech in a noisy phone environment, while in the ams active noise reduction technology With support, the call will be conducted in a nearly silent background sound, making phone communication easier. AS3415 is a feed-forward active noise reduction speaker driver IC, its low power consumption, excellent audio performance and small size are perfect for Ascend Mate 7 headphones. Unlike other digital noise reduction solutions that control the speaker output through software, the ams speaker driver uses pure analog circuits, which requires less than half the power consumption of the digital noise reduction solution. At the same time, the functions necessary for active noise reduction are integrated in the AS3415 circuit, requiring only a few small external components, saving the headphone space. The AS3415 high-fidelity audio playback function gives Ascend Mate 7 headphones excellent sound quality. The total harmonic distortion rate of AS3415 is usually only 0.004%, and the signal-to-noise ratio is higher than 110dB (in the case of 32 ohm load and 34mW output). Under standard conditions, AS3415 can reduce the noise by 95%. Oliver Jones, director of ams and general manager of the audio sensor business, said: "The new Ascend Mate 7 mobile phone headset with active noise reduction is a major breakthrough for Huawei to meet high-end smartphone consumer demand. The AS3415 active noise reduction speaker driver will be for mobile phone users. Brings clear sound quality and near-silent background sound. " Bruce Li, Vice President of Headphone Product Line of Huawei Consumer Products Business Unit, said: "Ascend Mate7 is Huawei's most high-end smartphone to date, adopting the latest innovative technologies to bring users a faster, lasting and efficient extraordinary experience. We will work with ams Work together to achieve superior sound quality and continue to meet consumer demand. " The AS3415 active noise reduction speaker driver is now in production, and its evaluation kit is now available on the ams official website.
