TWS technology is based on the development of Bluetooth chip technology. Its working principle means that the mobile phone can be connected to the main headset through the main headset, and then the main headset can be quickly connected to the auxiliary headset through wireless mode to achieve the true wireless separation of left and right channels.
In 2016, Apple officially released AirPods wireless headphones, and since then, TWS (True Wireless Stereo, true wireless stereo) headphones were born.
At present, AirPods has evolved to the third generation. The stability of the call, noise reduction performance and standby time have brought a deep impression to users, becoming the industry benchmark for TWS headsets and triggering a wave of wireless headset reform. Therefore, the popularity of AirPods has cultivated TWS earphones as a new generation of consumer electronics explosives.
Analysis of the five main characteristics of TWS headphonesAccording to the latest IDC data, global headphone / audible device shipments in 2019 were 170.5 million pairs, a 2.5-fold increase from 48.6 million pairs in 2018. From the perspective of the ODM / OEM industry chain, it is estimated that from 2020 to 2022, global shipments of TWS headsets (including AirPods) will be 1.67, 2.57 and 410 million pairs, respectively.
1. What is TWS earphone?TWS, true wireless stereo, TWS technology is developed based on Bluetooth chip technology. Its working principle is that the mobile phone is connected to the main headset through the main headset, and then the main headset is quickly connected to the sub headset through wireless mode, so as to realize the real Bluetooth wireless separation of the left and right channels.
In fact, Bluetooth headset technology and products have been developed for many years, but due to the uneven product and quality, the entire industry is in chaos. Until Apple released the world's first TWS Bluetooth headset AirPods, this product supports the connection of many of Apple's ecological products (Iphone, Ipad, iwatch, Macbook), wireless headphones with built-in optical sensors and accelerometers. Double-click this wireless headset can also access Siri. During the phone call, this headset can also reduce noise and filter noise to ensure sound quality. At the same time, the domestic and foreign AI fields are booming. With the help of AI, the TWS technology rides on the express train of the "smart" era, and the Bluetooth headset has renewed its vitality.
2. What are the main features of TWS?
The main features of TWS headphones are:
Analysis of the five main characteristics of TWS headphones
(1) True wireless: Abandon the trouble of earphone wire winding
The WS Bluetooth headset does not require a wired connection, getting rid of the traditional headset's wired restraint; the two left and right headsets form a stereo system through Bluetooth, which improves listening to songs, talking, and wearing. If you add professional acoustic pickup technology, intelligent noise reduction technology & AI algorithm noise reduction technology, etc., you can achieve a perfect sound experience: ear-worn voice, video calls, music enjoyment, mountain running, safe driving, etc. are not constrained .
(2) Binaural stereo: improve sound quality and improve call quality
From the perspective of the product, audio and video experience is the focus of most attention on the TWS headset, so the noise reduction function is an indispensable technology of TWS.
(3) Multiple perception: enhance user experience and create intelligent voice
TWS headphones experienced the path of semi-intelligent headphones in the era of crazy development in 2018. Many Bluetooth chip manufacturers have upgraded in version 5.0, embedded serial flash memory, can be more flexible to upgrade customer software, support third-party software migration; cooperate with the original ecology or content delivery (audio content, headlines, health Zi Xun, financial dynamics, sports information, etc.) have opened their ports, in fact, there is a lot to do in the content area.
Nowadays, the mainstream front-line gods are all involved in the field of artificial intelligence, and they are all building their own intelligent ecological chain. Microsoft, Google, and Amazon have been used as examples to extend Microsoft Cortana, Google Assistant, and Amazon Alexa wireless intelligent voice interaction services. Battle for smart end users.
Similarly, domestic hardware manufacturers, including mobile phone manufacturers, support their voice assistants. Huawei's TWS supports Xiaoyi in their mobile phones, and Xiaomi TWS supports Xiaoai students.
(4) Small size: comfortable to wear, convenient to use and easy to carry.
