Recently, the latest statistics from Canalys, an international research organization, showed that the growth of the global personal smart audio market was hindered in the second quarter of this year. TWS headphones were the only personal smart audio equipment category that achieved growth, an increase of 8% to 63 million units. Apple continued to lead the global TWS headset market in the second quarter, with overall shipments reaching 15.3 million units. Sherry Jin, research analyst at Canalys, said: “Apple will rely on its widely anticipated AirPods Pro2 to drive shipments in its wearables, home and accessories categories in the coming quarters. The AirPods Pro2 will not only deliver on battery life and good performance, etc. It must also be able to provide innovative features for novel uses.”
On September 18, at the 2022 Apple Autumn Conference, Apple’s new generation of active noise-cancelling headphones, AirPods Pro2, was officially released. ? The hot comments on Bilibili and Weibo are: 1. Double the noise reduction. Thanks to the AirPods Pro 2 equipped with the new Apple H2 chip, this wireless earphone has a computational audio algorithm, and the noise reduction has been improved by 2 times. Bluetooth has been upgraded from 5.0 to 5.3, adding adaptive transparency mode.

2. Apple has added a capacitive sensing layer to the handle of the headset, and users can adjust the volume by sliding the handle, which increases the interactive mode of sliding touch. Some user comments: I was pleasantly surprised that AirPods Pro 2 finally added the function of controlling the volume. Before, the volume of the headphones could only be adjusted through the iPhone or Apple Watch. It was really troublesome to use. Swipe up and down on the headphone handle to adjust the volume, and the volume is also adjusted bar by bar.
In fact, long before the AirPods headset was equipped with the touch sliding function, other high-end TWS headset brands such as Huawei, OPPO, and Xiaomi have widely adopted the pressure-sensitive + touch interactive solution. Apple’s upgrade of this function proves that the interactive solution combining pressure and touch has been widely recognized by the industry and the market, representing the future development trend of TWS headset intelligent interaction.
What is the market application prospect of multifunctional interactive sensor solutions? Which manufacturer first introduced the pressure-sensitive + touch interactive solution? What are the unique advantages of Goodix’s pressure-sensitive + touch interactive solution compared to traditional solutions in terms of power consumption and integration? In addition to TWS earphones, what are its broad application prospects?
The multi-functional interactive sensor is mainly used in the smart wearable market. According to the latest report of ABI Research, the global shipment of wearable devices is expected to reach about 344 million units this year. It is estimated that by 2027, the global shipment will exceed 650 million units. The CAGR between 2027 and 2027 is 13.2%.
As the pioneer of multi-functional interactive sensor solutions, Goodix Technology released the world’s first in-ear detection + touch two-in-one solution in 2019, providing a sensitive and intelligent complete interactive solution for TWS headsets, breaking touch The common shortcomings of sensors are “easy to touch by mistake, single function” and so on.
Keeping up with the development trend of TWS headsets, Goodix Technology will take the lead in launching an all-in-one TWS headset interactive solution such as wearing detection + touch sliding + pressure sensing + body temperature detection in 2021, and provides wearing + pressure sensing for different grades of TWS headsets , wearing + touch, sliding + pressure sensing and other high-performance solutions to meet the customized needs of customers for flexible development. For example, the OPPO Enco X2 TWS headset adopts the wearing + sliding + pressure sensing solution of Goodix Technology, and the latest TWS flagship headset released by Xiaomi uses the wearing + pressing detection solution of Goodix Technology, etc.

The wide application of this multifunctional interactive sensor in TWS headsets benefits from the unique technical advantages of Goodix Technology. According to the company, its solution features high integration, high performance, high cost performance, and high quality.
●In terms of high integration, the main performance advantages: support up to 9 channels of self-capacitance and mutual-capacitance detection sensors; support two-way Wheat bridge analog front-end; the chip integrates MCU to support highly flexible development.
●High performance is mainly reflected in the aF-level capacitance detection resolution, which supports maximum 300 pF offset capacitance cancellation; 24-bit high-precision ADC supports pressure detection; industry-leading interference suppression and environmental adaptability.
●High cost performance, can provide customized solutions for low, medium and high TWS earphones of different levels. Supports multi-function integration: any combination of wearing detection + pressure detection + sliding detection + temperature detection; supports up to 9 channels of proximity sensing and touch gesture applications; cost advantages, support customized development.
●High quality. Goodix provides TWS earphones with a variety of high-performance solution combinations such as wearing + pressure sensing, wearing + touch, sliding + pressure sensing, etc. With large-scale commercial application cases and successful development experience, it can provide a full range of chips and algorithms. support.
It is understood that in order to accelerate the wider penetration of the solution for different positioning of TWS headphones, Goodix Technology not only supports the traditional resistive pressure detection solution, but also launched a cost-effective capacitive pressure detection solution with complete intellectual property rights. This solution does not need to be equipped with an additional resistive pressure sensor, and only needs to be equipped with a simple FPC design to achieve pressure sensing and sliding functions. It is a one-stop TWS headset interaction solution that takes into account performance and cost.
In addition to TWS headsets, what are the usage scenarios of multi-functional interactive sensors that people are interested in? According to Huiding Technology, the multi-functional interactive sensor is mainly used in smart wearable devices such as watches, wristbands, AR/VR glasses and handles, and supports various applications of wearing detection and human-computer interaction. This solution can also be applied to mobile phones, tablets, active pens and other products, providing functions such as proximity sensing, press detection and game touch buttons; in other electronic devices such as smart home appliances, this solution can support wearing, proximity sensing, touch, Compression and customized application.
