Embedded Algorithms Used to Improve Speaker Output
We are constantly struggling with the poor sound output offered by speakers fitted in our mobile devices. As compared to regular speakers, they also have a shorter life span and can wear out pretty quickly. But today we have a solution to this problem in the form of embedded algorithms which are used for enhancing speaker output.
The installation of circuits can help in monitoring the performance of the speakers and also prevent damage. For instance, excursion control measures can prevent the over-excursion of the speaker membrane. Similarly, real-time temperature protection will prevent overheating of the voice coil.
An example of the use of embedded algorithms is seen in the NXP audio system. The system is incorporated in a wafer-level cost-efficient, small chip-scale package with an embedded DSP which runs advanced algorithms to boost speaker output and also offers speaker protection. It also has a high performing audio amplifier as well as a smart DC-to-DC converter. With environmental awareness, the system can automatically adapt to thermal and acoustic changes. The sophisticated clip controller avoids the occurrence of clipping even when there is poor voltage supply. So you get a loudest possible sound from even smaller speakers fitted in your smartphones, tablets and other such devices.
