3C Industry-TWS Headphones

TWS is the abbreviation of True Wireless Stereo, which means True Wireless Stereo, realizing the use of true Bluetooth left and right channel wireless separation.

A few days ago, the research organization Canalys released a report on the global smart personal audio market in the third quarter of 2023, showing that the global shipments of smart personal audio products reached 110 million units in that quarter, and due to the continued penetration of the mass market, TWS headphones have accounted for 73% of the total shipments. At the same time, with a more affordable price, TWS headphones continued to dive into the low-end market and achieved more market share.

Accompanied by the maturity of Bluetooth, chips, sensors, and other technologies, TWS headphones will accelerate the development, is expected to become the fastest-growing field of smart wearable devices, and the global market size is forecast to reach $40.13 billion in 2024.

0 TWS assembly and testing production line industry process

TWS headphones are mainly composed of a charging box part and a wireless headset part, where the charging box includes devices such as Li-ion battery packs, power PCB components, battery management ICs, LED charging indicator modules, etc. The wireless headset part includes chips (e.g., Bluetooth chips, power management chips, etc.), sensors (e.g., acceleration sensors, distance sensors, etc.), batteries, microphones, and other electronic devices.

The TWS headphone production line is divided into three parts: pre-processing, product assembly, and packaging.
