MEMS or micro electro mechanical systems have existed for some time, and this technology has allowed the miniaturization of various things If you are not familiar with MEMS, simply put, it is a method of making movable parts from the same type of silicon, which makes semiconductors in the same type of wafer factory.
Xmems is a company specialized in manufacturing what the company calls micro speakers using MEMS technology. The first earphone based on its micro speakers should be available later this year. The company demonstrated a 3D printing model with an OEM manufacturer named Vencer on Computex
The 3D printed model has no amazing appearance, and the matching is far from perfect, especially the installed foam earplugs do not form a proper seal for you. Therefore, it is impossible to make any kind of sound quality judgment at the exhibition site, but it seems that MEMS earphones and balance armature have a lot in common, that is, they need good sealing to make a good sound.
The demo device is connected via usb-c. what is not shown in the picture is a fairly large and ugly three button control unit on the wire, which also contains a cx31988 audio decoder from Synaptics. An interesting aspect of MEMS speakers is that they can be used in both open and closed modes, where open mode will be used for environmental modes such as making a phone call or instead of enabling ANC type earplugs. The closed mode will work like a pair of ordinary drive units in an ordinary earplug.
I hope we can see the final product without waiting too long, and it can be bought in the market. However, there is no specific information about when the retail products will be launched, but the relevant manufacturers say that they will be launched later this year.
