July 29, 2014 - Recently, NXP Semiconductors (Nasdaq: NXPI) and AAC Technologies (hereinafter referred to as "AAC Technologies") conducted a joint experiment and successfully completed Tested for the life of mobile smart Speaker horns. Through this joint experiment, the two 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 complements AAC's high-performance Miniature Speaker DMSP0916S, perfect for portable devices such as smartphones and tablets, and improves mobile The loudness of the audio equipment and enhanced sound quality. During the experiment, the technicians of both parties discussed the parameters of the speaker and amplifier for the protection algorithm on the NXP TFA9890 intelligent power amplifier after in-depth discussion. The AAC speaker with rated power of 0.67W was safely driven to 4W and passed. The overall system reliability life test. In addition, through in-depth cooperation between the two parties, NXP and AAC Technologies have jointly defined the relevant parameters of the speaker and intelligent power amplifier, such as Xmax, Tmax, etc., and reached a unified test method.
The NXP TFA9890 smart power amplifier solution, which integrates the DC/DC converter to achieve an unparalleled 9.5V boost voltage, increases the voltage margin of the audio driver IC, preventing the amplifier from clipping and maximizing Maintain a high sound quality at the volume. The TFA9890 is currently the most powerful driver for micro-speakers. With AAC's high-reliability and high-performance standard speakers, it can safely output a rated power peak of up to 4 W, significantly improving the phone, The sound output and sound quality of the 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 jointly improved the mobile audio industry standards and improved the external effects of mobile audio. The results of the experiment also prove that our solution design guarantees the quality of mobile devices such as mobile phones in their life cycle. For the end consumers, mobile devices equipped with NXP smart power amplifier technology can make consumers enjoy Better music playback."
"Audio Technology's DMSP0916S speaker adopts 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 level, and can be used with NXP The horn protection algorithm is perfectly matched. At present, the overall scheme has passed the joint testing and certification of both parties, demonstrating the excellent performance and high reliability of the overall audio system. Both parties plan to include the relevant parameters defined by the joint experiment in the new product. In the application manual, the speaker protection intelligent power amplifier chip provides excellent and reliable speaker application parameters, and the value of the smart chip is optimized.†Mr. Zhu Bingke, vice president of R&S and R&D, fully affirmed the results of the experiment. He said: “The future , we will be in more models of speakers
Carry out tests to further optimize the performance of the speaker and improve the speaker parameter standards including the rated power, and hope to take the industry standard to a new height! â€
As early as 2012, NXP pioneered the definition of "Smart Amplifier", a new generation of revolutionary amplifier solutions for portable devices. After the launch of the program, it has achieved great market response. So far, NXP has sold more than 100 million smart power amplifier chips worldwide, designed and adopted by famous mobile phone manufacturers. Nowadays, as the design of mobile terminals such as smart phones becomes more and more light and thin, the design space for placing speakers will continue to shrink in the future. How to improve the sound quality of mobile terminals is becoming a design challenge. In an effort to achieve better sound quality and greater output volume, leading handset manufacturers are also beginning to increase the internal voltage used to drive the microspeakers. To this end, both parties to this joint experiment, NXP Semiconductors and AAC Technologies, will spare no effort to promote the application of the experimental results, and together with the partners, through the leading intelligent power amplifier solutions, including high and medium The low-end intelligent mobile terminals at all levels achieve Hi-Fi high-quality sound.
