Let’s face it, the sound quality coming from the tiny speakers on our mobile phones can in no way compare to that of a proper speaker. However there are times when we need those speakers, i.e. calls made on speaker phone, video calls, watching a YouTube video with many people, etc. Well the good news is that NXP has introduced a new audio chip today dubbed the TFA9887 which is supposed to help improve the sound quality on micro speakers which are commonly found on mobile devices such as smartphones and tablets.
Featuring the company’s CoolFlux audio DSP, a class-D amplifier with current sensing and a DC-to-DC converter, this should not only help boost the output level by five times, but will reportedly not damage the drivers in the process. The class-D amplifier will also help deliver a strong and clear signal regardless of battery level (this could be a good or bad thing), and the chip will ultimately help produce a louder and richer sound with a tighter bass. However given that these are micro speakers we’re talking about, we’re sure that many probably didn’t expect much to begin with, right? In any case we wouldn’t exactly say no if this chip finds its way into our mobile devices in the future.
