vivo X Fold3 Debuts Global Premiere of Rivet Sound Technology Whisper Speaker and AeroEngine

Lightweight yet powerful! On March 26, vivo's annual folding flagship X Fold3 made a dazzling appearance. As possibly the lightest large foldable in the industry, the vivo X Fold3 weighs only 219g, with an unfolded thickness of just 4.65mm. In terms of perceptual experience, vivo has innovatively collaborated with Rivet Sound Technology to tailor a super-light and thin touch-and-listen solution for the X Fold3—the "Privacy First Class Dual Speaker" scheme and the "Foldable-specific Touch Sensation Solution," making the touch-and-listen experience "lightweight yet substantial"! The Whisper Speaker: Innovatively Ensuring Hardware-Level Call Privacy

With the power of the Whisper Speaker, vivo has brought the exclusivity of first-class privacy into mobile calls, introducing the privacy call feature for the first time on the X Fold3, meeting the stringent demands of business users for security and privacy.

The Whisper Speaker is the first dual-diaphragm leak-proof speaker from Rui Sheng Technology. It adopts an innovative dual-drive side-by-side design, which can be used both as a receiver with privacy call functionality and as a speaker for external audio playback, allowing users to chat with peace of mind and immerse themselves in clear sound. (Note: The side-by-side design refers to its two independent diaphragm voice coils, and the dual-drive means it can achieve both in-phase and out-of-phase driving modes.) Handset Mode: Anti-Phase Driving for Private Conversations

During phone calls (in handset mode), the two diaphragms in the Whisper speaker undergo anti-phase driving, resulting in a canceling effect on sound waves. This reduces sound leakage, ensuring that the sound remains confined near the ear and effectively prevents others nearby from overhearing private conversations. Whether in an office, elevator, or other public settings like trains or taxis, X Fold3 users can rest assured that their privacy is protected.

• After testing in the Rui Sheng Technology Acoustic Laboratory, the Whisper speaker demonstrated an average doubling (4dB) of mid-low frequency isolation compared to other typical phones on the market, effectively suppressing sound leakage.
• Speaker Mode: In-phase drive for immersive sound In noisy environments during external sound playback (speaker mode), the two diaphragms in the Whisper speaker work in phase, amplifying the volume under mutual cooperation to create a clear and immersive sound effect. According to tests conducted in the Rui Sheng Technology Acoustic Laboratory, the Whisper speaker excels in the mid-low frequency range, particularly with a performance increase of over 1x compared to traditional speakers in the low-frequency domain. The bass is robust and powerful, the midrange is clear and balanced, and the sound details are exceptionally rich.
• Beyond ultimate thinness, it also offers outstanding immersive stereo experience Within the stacked design of the folding machine, every 0.01mm thickness and 0.1g weight saved represents a significant technological breakthrough. Rui Sheng Technology's "Privacy First Class Dual Speaker" solution contributes to the X Fold3's achievement of a "record-breaking thin and light" body. Notably, Rui Sheng Technology's ultra-thin speaker may be the thinnest high-performance speaker in the industry, with a single unit thickness reaching an extreme thinness of 1.8mm, greatly saving stacking space. The Whisper speaker weighs as little as 0.95g, with a thickness of only 2.15mm, possibly making it the thinnest and lightest shoulder-to-shoulder dual-diaphragm leak-proof speaker in the industry. In addition to its ultra-thin design, the "Privacy First-Class Dual Lift" solution excels in sound experience as well. With the support of the Rui Voice Technology's super-linear speaker technology platform, this solution delivers an excellent immersive stereo experience for the X Fold3: from the booming cinematic background sound, to the subtle music rhythms, to the delicate game footsteps, coupled with the X Fold3's foldable giant screen "Sky Curtain," users can immerse themselves anytime, anywhere, and enjoy an immersive auditory experience.

Debuting the AeroEngine ultra-light high-performance X-axis motor, ushering in the "1 Gram Era."

In terms of touch, the X Fold3 debuts with the AeroEngine ultra-light high-performance X-axis motor specially customized by Rui Voice Technology for folding machines. Weighing only 1g, it may be the lightest X-axis motor in the industry, while its thickness is as thin as 2.4mm, helping the X Fold3 create a tactile experience of "lightweight 'vibration' and outstanding strength." Comparing to the motors used in the previous generation, the AeroEngine boasts greater vibration, faster start-stop capability, and a wider frequency range. This enables it to simulate stronger vibrations, provide more responsive and nuanced feedback, leading to a qualitative leap in the tactile experience of the X Fold3. Additionally, with the support of the RichTap® tactile solution, the X Fold3 can adapt to a broader range of high-quality tactile ecosystems, meeting users' demands for high-quality vibration experiences across various mainstream applications such as input methods, gaming, multimedia, etc., making every interaction a thrilling experience.

The collaboration between RuiSheng Technology and vivo in breaking conventional norms has brought about exclusive innovative products, demonstrating that slim design and exceptional experience are not mutually exclusive. This breakthrough enhances the perceptual experience of foldable devices. In the future, RuiSheng Technology will continue to focus on innovation, continuously creating a better perceptual experience for the world.
