Redmi Note 7 made its debut surprising everyone with its excellent value for money and among its many strengths, the company has decided to focus on emphasizing above all its 48 MP camera. But nobody seems to talk about the quality of his main speaker, which reproduces a really full and powerful sound, despite its mono nature.
On the official Redmi channel on Weibo, the company has today finally decided to go into details, explaining how they came to this result. The smartphone adopts a large soundbox, separated from the main one, which leads to a huge increase in volume and sound quality. Space is important, but not enough to give good results if the electronic components are not up to: Redmi Note 7, however, uses sound diffusion components (PA) from the same supplier of Samsung and Apple . Finally, thanks to the use of a DSM dynamic gain control and a custom AAC micro-speaker, the volume is increased up to 2.5 times.
To all this is added the mode that allows you to increase the maximum call volume by a further 40% by simply pressing the volume key, if needed. To crown the quality of the calls, the two noise-suppressing microphones guided by the AI and the main “anti-obstruction” microphone are then taken into consideration. What to say, nothing seems to have been left to chance in this smartphone, which despite the price has shown not to neglect the quality of any of its appearance.
