Recently, BYD officially declassified several configurations its new concept car, X- Dream, for the first time. This included a new dragon face shape, 3D Chinese knot taillights, a touch LCD screen, and a translucent leather detail for intelligent interaction. The model, first unveiled at the 2021 Shanghai Auto Show, has a stylish eye-catching exterior and user-friendly technology. According to BYD, the X-Dream’s automotive audio system module adopts AAC’s full-stack solution, which creates a futuristic and intelligent cockpit audio system through micro-acoustic technology, with both an aesthetic and sci-tech sensory feel. Its unique sky 3D surround audio field, independent sound zone, and non-porous interior design will bring a new immersive sound experience.
A small and light form factor enables flexible installation
As a world-leading supplier of intelligent equipment solutions, AAC has developed two innovative products for the BYD X-Dream: an ultra-thin full-range speaker and an ultra-thin woofer, which is small and light and provides a wide frequency range. These features enable more flexible installation, thus simplifying acoustic design, reducing design costs, improving acoustic performance, diversifying the sound field, increasing vehicle efficiency, and isolating the vibration effect.
Hidden design and Atmos sound make for an immersive 3D sound field experience
AAC’s new automotive speakers are designed with a sound guide tube and narrow slit for sound to ensure great sound quality while optimizing the interior design, realizing the integration of holes and shape. The unique all-in-one non-porous interior allows passengers to ‘hear but not see’ the speakers, creating a sense of novelty and mystery while offering passengers a new driving experience.
The X-Dream cockpit roof is equipped with ultra-thin speakers that apply customized sound algorithms, which upgrading 2D sound field to 3D, enhance the sound field stereo, and bring a more immersive experience to passengers.
Directional sounding and independent sound zone make for a private in-vehicle concert hall
X-Dream achieves directional sound inside the car through a precisely deployed micro-speaker array and micro-headrest speakers, giving passengers in different areas an independent sound zone that does not impact anyone else.
According to an AAC R&D engineer, the personal sound zone (PSZ) technology developed by AAC has shattered the traditional mode ‘one sound fits all’ to truly realize a customized sound experience for each passenger. In the future as autonomous driving technology matures, intelligent vehicles will be able to provide more immersive multimedia content for each passenger. Sound should not be functionally positioned solely as a carrier of information, but rather as a new interaction experience between audio and visual media. PSZ technology can not only make vehicles more intelligent, but also make them more enjoyable for users!
