NXP and AAC Technologies join forces to improve the mobile audio industry standard

July 29, 2014-Recently, NXP Semiconductors (NASDAQ: NXPI) and AAC Technologies Holdings Limited (AAC Technologies, hereinafter referred to as "AAC Technologies") conducted a joint experiment and successfully completed Tested for the life of smart amplifier speakers for mobile devices. Through this joint experiment, both parties not only verified each other's technology, but also further improved the industry standards, bringing a better listening experience for mobile terminal users such as smartphones and tablets.

In this experiment, NXP ’s innovative Smart Amplifier (TFA98XX series) and AAC ’s high-performance miniature speaker device (DMSP0916S) complement each other, perfect for portable devices such as smartphones and tablets, and improve mobile The loudness of audio equipment, and enhance the sound quality effect. During the experiment, the technical personnel of the two parties have reasonably configured the parameters of the speaker and the amplifier used for the protection algorithm on the NXP TFA9890 intelligent power amplifier, and safely driven the AAC speaker with a rated power of 0.67W to 4W, and passed Reliability life test of the overall system. In addition, through in-depth cooperation between the two parties, NXP and AAC have jointly defined relevant parameters such as Xmax and Tmax when using the speaker with the intelligent power amplifier, and reached a unified test method.

The NXP TFA9890 intelligent power amplifier solution participating in this experiment integrates a DC / DC converter to achieve an unparalleled 9.5V boost voltage, increasing the voltage margin of the audio driver IC, preventing the amplifier from clipping peaks, and at the maximum Maintain high sound quality at the volume. TFA9890 is currently the most powerful driver for miniature speakers. With the high-reliability and high-performance standard speakers of AAC Technology, it can safely output a peak power rating of record-breaking 4 W, which significantly improves mobile phones, The sound output and sound quality of micro-speakers on portable devices such as tablets, while providing greater volume, better sound quality and thicker bass, will not cause damage to the speakers.

Vincent Pronk, general manager of NXP Semiconductors ’Global Mobile Audio product line, said,“ NXP and AAC have passed this test to jointly raise the standards of the mobile audio industry and improve the performance of mobile device audio. At the same time, this The results of the second experiment also prove that the design of our solution has guaranteed the quality of mobile phone and other mobile device speakers during their life cycle. For end consumers, mobile devices equipped with NXP smart power amplifier technology can enable consumers to enjoy Better music playback. "

"AAC's DMSP0916S loudspeaker uses advanced technology and quality control standards in the design and production process to improve the reliability of the speaker unit and box, reduce low-frequency distortion, improve amplitude symmetry and consistency. The speaker protection algorithms are perfectly matched. At present, the overall scheme has passed the joint test certification of both parties, showing the excellent performance and high reliability of the overall audio system. Both parties plan to include the relevant parameter definitions derived from this joint experiment in the new product. The application manual provides excellent and reliable speaker application parameters for the speaker protection smart power amplifier chip, and maximizes the value of the smart chip. "Mr. Zhu Bingke, Vice President of R & D of AAC Technology fully affirmed the experimental results, he said: , We will be in more models of speakers

Conduct experiments to further optimize and strengthen speaker performance, and improve various speaker parameter standards including rated power, hoping to take this industry standard to a new height! "

NXP pioneered the definition of "Smart Amplifier", a new generation of revolutionary amplifier solutions for portable devices, as early as 2012. After the program was launched, it achieved a huge market response. So far, NXP has sold more than 100 million smart amplifier chips worldwide, designed and adopted by major mobile phone manufacturers. Nowadays, as the design of mobile terminals such as smart phones becomes more and more lightweight and flat, the design space for placing speakers will continue to shrink in the future. How to improve the sound quality of mobile terminals has become a design challenge. In an effort to achieve better sound quality and greater output volume, leading mobile phone manufacturers have also begun to increase the internal voltage used to drive micro-speakers. To this end, the two sides of this joint experiment, NXP Semiconductors and AAC, will spare no effort to promote the application of the experimental results, and together with partners, through leading intelligent power amplifier solutions, including high, middle and high , Low-end intelligent mobile terminals at all levels to achieve Hi-Fi high-quality sound.
