So light, yet so powerful! On March 26, vivo’s annual flagship foldable X Fold3 made a lightweight appearance. As possibly the lightest large foldable phone in the industry, the vivo X Fold3 weighs only 219g, with a thickness of only 4.65mm in its unfolded state. In terms of sensory experience, vivo has collaborated with AAC Technologies to tailor an ultra-light and thin haptic and audio solutions for the X Fold3 – it features a first-class privacy dual speaker and foldable devices specific haptic solutions. This combination allows the X Fold3 to provide a haptic and audio experience that is light yet substantial!
Whisper Speakers: Innovatively Achieving Hardware-Level Call Privacy Protection
Empowered by the Whisper speaker, vivo has seamlessly integrated privacy protection from a first-class cabin into mobile phone calls. vivo achieved for the first time on the X Fold3 calls that are truly private to better meet the strict requirements for security and privacy among business users.
The Whisper speaker, developed by AAC Technologies, is the industry’s first side-by-side dual-diaphragm anti-leakage speaker. It features an innovative dual-drive side-by-side design, serving as both a handset for private calls and a speaker for external audio playback, allowing users to converse without worrying about privacy. (Note: The side-by-side design means it has two independent voice coils and diaphragms.The dual-drive capability refers to the ability to achieve both in-phase and reverse-phase drive modes.)
1) Handset Mode: Reverse-Phase Drive for Private Calls
During a call (in handset mode), the two diaphragms within the Whisper speaker are driven in reverse-phase, mutually canceling the sound waves. This reduces sound leakage and ensures the privacy of the call by ensuring that the sound propagates near the ear. Whether in an office, elevator, or other public places such as high-speed trains and taxis, X Fold3 users do not need to worry about others overhearing private information.
(Whisper Speaker Position and Private Call Functionality)
(According to tests conducted by AAC Technologies’ acoustic lab, compared to other typical phones on the market, the Whisper speaker has doubled (4dB) the average isolation in the mid-low frequency range, effectively reducing sound leakage.)
2) Speaker Mode: In-Phase Drive for Immersive Audio
When playing audio in noisy environments (in speaker mode), the two diaphragms within the Whisper speakers are driven in-phase, working together to amplify the volume and create clear and pleasing sound. According to tests conducted by AAC Technologies’ acoustic lab, the Whisper speaker excel in the mid-low frequency range. Particularly in the low frequency, the performance is more than double that of traditional speakers. The speaker delivers powerful and rich bass, clear and balanced mid range, and extremely detailed sound.
Beyond Ultra-Slim: Exceptional Immersive Stereo Experience
In the stacking design of foldable devices, each millimeter and milligram counts. Saving even the smallest space can represent a significant technological breakthrough. AAC Technologies’ first-class privacy dual speaker aids the X Fold3 in creating an unprecedentedly slim body.
Among these innovations, AAC Technologies’ ultra-thin speakers may be the thinnest high-performance speakers in the industry, with a single unit featuring an extreme thickness of 1.8mm, greatly saving stacking space. The Whisper speaker weighs as little as 0.95g and is only 2.15mm thick, possibly the industry’s lightest and thinnest side-by-side dual diaphragm anti-leakage speaker.
In addition to the ultra-slim design, the first-class privacy dual speaker also excels in acoustic experience. With the support of AAC Technologies’ ultra-linear speaker technology platform, this solution can provide the X Fold3 with an outstanding immersive stereo experience,including the grand and powerful background music of movies, the fluctuating rhythm of music, and the subtle footsteps in games. With the X Fold3’s giant “skylight” foldable screen, users can enjoy an immersive auditory experience anytime, anywhere.
Unveiling the AeroEngine Ultra-Light High-Performance X-Axis Motor, Pioneering the “1g Era”
In terms of haptics feedback, the X Fold3 debuts with the custom AeroEngine ultra-light high-performance X-axis actuator, exclusively for foldable devices, developed in collaboration with AAC Technologies. Weighing just 1g, it may be the lightest X-axis actuator in the industry, and with a thickness of only 2.4mm, it helps the X Fold3 deliver a lightweight yet powerful haptic experience.
Compared to the actuator used in the previous generation, the AeroEngine offers greater vibration intensity, faster start-stop, and a wider frequency range. It is capable of simulating stronger haptic feedback, more responsive interaction, and more detailed and varied vibration effects, bringing a huge leap to the haptic experience of the X Fold3. Additionally, empowered by the RichTap® haptic solution, the X Fold3 can adapt to a broader high-quality haptic ecosystem. It meets users’ demands for premium vibration experiences in various mainstream applications, including input methods, gaming, and multimedia. Every interaction triggers a delightful response.
This exclusive innovative product, developed through the collaboration between AAC Technologies and vivo, achieves a slim design and exceptional experience at the same time. It represents a breakthrough in the sensory experience of foldable devices. Looking ahead, AAC Technologies will continue to focus on innovation, persistently creating even more delightful sensory experiences for the world.
