Yiyi PR100MKII in-ear headphones violent dismantling

The PR100MKII features a dual diaphragm design with two independent sounding diaphragms on one side. What is the internal structure of this headset? How does the double diaphragm work? We carried out a violent dismantling of the masses and loved them for study and study. From the dismantling situation, PR100MKII does use two diaphragms, one of which is the diaphragm of the drive, and the other is a separate diaphragm, which is located at the back of the earphone housing, at first glance The passive diaphragm designs that are often seen in miniature speakers are very similar, but in reality they are essentially different: the independent diaphragm of the PR100MKII is not intended for vocalization, but for controlling the pressure inside the chamber. Thus, a design that adjusts the pressure balance inside and outside the chamber has advantages and disadvantages as compared with the more common way of opening.
