The latest audio chip from NXP will make your phone sound sound closer to the stereo system. By analyzing and increasing the volume (not distortion) through the internal feedback circuit, the chip can monitor the speaker status in real time. You can take the essence to the dross, so that the sound quality is significantly improved. Motorola's Moto X and Droid Ultra have used the 9-volt NXP TFA9890 chip, only need a single speaker to achieve close to the performance of the HTC One series (to I know that the One series is two speakers controlled by a 5-volt NXP chip.) However, moto is not the latest product, and NXP's latest mobile phone speakers are still under development.

The next-generation NXP TFA9895 is expected to be launched at the 2014 Mobile World conference. The development of the TFA9895 does not have the option to continue to increase the voltage. Instead, it chooses to separately process different frequency bands to further reduce noise.
In a live audition, the engadget reporter selected 4 songs, and 3 of them could tell the difference between using TFA9895 or not - the 4th Sk8er Boi because the volume of each band is very close, resulting in a general effect of the chip, no distinction. The final conclusion is that the TFA9895 chip is obviously more effective. You don't even have to put your ear close to the phone, you can directly hear how it differs from the traditional mobile phone. This chip will be available in 2014.
