Application of Decowell Remote IO in TWS headphone production line

1、TWS headset introduction


TWS full name is TrueWirelessStereo, meaning true wireless stereo, TWS technology is based on the development of Bluetooth chip technology. Its working principle is that the phone by connecting the main headset, and then the main headset through the wireless way to quickly connect the secondary headset, to achieve true Bluetooth left and right channel wireless separation use.

Without the wire connecting the left and right units, which makes their batteries and control circuitry must also be built into the headset cavity, and the increased volume of the cavity, bringing more rich features. In many TWS headphones are integrated inside the voice assistant, gesture control, active noise cancellation and other relatively "technological" features.

       

When TWS headphones were first introduced in 2016, global sales were only 9 million, but by 2020 they will have reached 230 million, an increase of 2556% in five years. It is foreseeable that TWS Bluetooth headset will be an ultimate form of headset segmentation.

3、Nanjing Decowell TWS headphone production line application cases   

Nanjing Decowell has been deeply involved in the industrial control field for many years and has been recognized by many customers. At present, the products are widely used in 3C, new energy, medical, logistics, automotive, textile, packaging, steel, mining, environmental protection and other industries. The following is the application case of Decowell remote IO in TWS production line.


3.1 TWS headphone production line    

The project is a TWS assembly and testing line, the number of our EX modules used in the whole production line is 20pcs (EX1100) + 400pcs (DI&DO), which mainly undertakes the assembly of the whole production line, signal acquisition and control in the testing process, replacing the original OMRON remote IO solution, saving cost and improving the stability of signal transmission on site for the customer.
