Imagine stepping into your car and being enveloped by sound that seems to come from everywhere at once, yet there are no visible speakers in sight. This is the exciting future that Continental, a leading German automotive technology company, is bringing to life with its innovative Ac2ated Sound Technology. This groundbreaking approach transforms any flat surface in your vehicle, including instrument panels and door trims, into a speaker, enhancing both audio experience and design aesthetics.<\/p>\n

How Does This Technology Work?<\/p>\n

At the heart of this technology are specially designed actuators that generate sound by inducing vibrations in the surface of the display. Think of it as turning your car’s dashboard into a sound chamber. This means that instead of relying on traditional speakers, which can take up valuable space and add weight, the entire surface can transmit sound in what Continental describes as \u201cexceptional quality.\u201d Whether it\u2019s music, navigation prompts, or alerts, the sound quality is designed to be immersive and clear.<\/p>\n

One of the standout features of this technology is its ability to create what\u2019s known as \u201cacoustic localization.\u201d This means that when a sound is produced, it can be perceived as coming from the direction of the display itself. This is particularly useful for drivers, as it naturally draws their attention to the relevant information, enhancing safety and usability. Imagine receiving a navigation prompt that seems to come directly from the map display rather than from a speaker hidden somewhere in the car. It\u2019s a subtle but significant shift in how we interact with in-car technology.<\/p>\n

Why Is This Important for Modern Vehicles?<\/p>\n

In-car audio is no longer just about playing your favorite tunes; it\u2019s about relaying crucial information to occupants. With the rise of advanced driver-assistance systems (ADAS), the need for clear, immediate communication within the vehicle has never been more critical. By integrating sound with visual displays, Continental is addressing this need head-on, making it easier for drivers to stay informed without losing focus on the road.<\/p>\n

Moreover, the potential applications of this technology extend beyond just instrument panels. Continental envisions integrating these actuators into various flat surfaces throughout the car\u2019s interior, such as headrests, A-pillars, and even the roof lining. This could lead to a dramatic reduction in the number of conventional speakers needed\u2014up to 40% less weight and a staggering 90% reduction in space. For context, a high-end audio system can have over 30 speakers, so the savings in weight and space could be substantial.<\/p>\n

What About the Sound Quality?<\/p>\n

When Continental first showcased the Ac2ated Sound Technology at CES in 2020, it was focused on creating a speakerless immersive sound system. The concept was likened to how the body of a violin resonates to produce sound. Different surfaces in the car can handle various frequency ranges, much like traditional speakers of different sizes. This means that, with the right setup, the audio experience could rival that of high-end systems currently available in luxury vehicles.<\/p>\n

Real-World Impact and Future Prospects<\/p>\n

As we look to the future of automotive design, this technology represents a significant leap forward. Not only does it promise to enhance the audio experience, but it also aligns with the growing demand for sleeker, more minimalist interiors. By eliminating the need for visible speaker grilles and bulky audio components, manufacturers can create a more aesthetically pleasing environment without sacrificing sound quality.<\/p>\n

The big takeaway? Continental\u2019s Ac2ated Sound Technology isn\u2019t just about eliminating speakers\u2014it\u2019s about rethinking how we experience sound in our vehicles. As this technology continues to evolve, we can expect a more integrated, immersive experience that enhances both safety and enjoyment on the road. So, keep an eye out; the next time you step into a car, it might just be a symphony of sound, all coming from surfaces you never expected.<\/p>\n","protected":false},"excerpt":{"rendered":"

German firm’s new tech enables an instrument panel or any flat surface to be a speaker<\/p>\n

\n

In-car audio is as much about relaying information to the occupants as it is listening to music.<\/p>\n

With that in mind, one of the latest ideas to emerge from Continental is an instrument display that doubles as a sound chamber to transmit sound without the need\u00a0for separate speakers.<\/p>\n

The display is based on the company\u2019s Ac2ated Sound Technology, which it began developing a number of years ago with audio specialist Sennheiser.<\/p>\n

An exercise in system integration, the display does away with the need for separate speakers, saving cost, weight and space.<\/p>\n

Sound is generated by actuators, which effectively turn the entire display surface into a speaker thanks to audible vibrations induced in the glass. It\u00a0can transmit all kinds of sound, including speech,\u00a0in \u201cexceptional quality\u201d.<\/p>\n

According to Continental, a further advantage is \u2018acoustic localisation\u2019. As humans, we can tell where a sound is coming from and tend to turn our heads in that direction.<\/p>\n

So when a spoken message or alert sound is produced by the display, the driver\u2019s gaze is drawn to the instrument it\u2019s related to, directing attention where it\u2019s needed.<\/p>\n

The thinking behind\u00a0the combined audio\u00a0and display technology comes from part of the team specialising in\u00a0vehicle acoustics and\u00a0also \u2018psychoacoustics\u2019,\u00a0the science of how\u00a0humans perceive sound.<\/p>\n

Although the main use of the display may be to relay information and link visuals and sound more closely, Continental says the actuator technology can be integrated into almost any existing flat component in a car\u2019s interior.<\/p>\n

By installing the actuators in door trims, headrests, A-pillars, the rooflining and so on, there\u00a0is the potential to get rid of all conventional speakers.<\/p>\n

That could provide aesthetic benefits (no need for speaker grilles) together with a significant saving of around 40kg (about the weight of multiple speakers and fittings in a high-end audio system) and a 90% reduction in the space needed, which Continental estimates at 30-40 litres depending on the number of speakers used.<\/p>\n

Some premium audio systems incorporate more than 30 speakers, so the packaging benefits could be substantial too, assuming the active surface technology can match them for the audio quality.<\/p>\n

When the original Ac2ated system was shown by Continental at CES in 2020, it was audio system-focused, rather than display-focused, and called the Speakerless Immersive Sound system. Then, it was integrated with Sennheiser\u2019s Ambeo 3D audio technology.<\/p>\n

As Continental said at the time, the concept is similar to the way the wooden body of a string instrument like a violin acts as a resonance chamber and the surface vibrates to project the sound.<\/p>\n

Different sizes of surfaces, such as an A-pillar compared with a door panel, handle various frequency ranges in the same way as specific types and sizes of speaker.<\/p>\n<\/div>\n","protected":false},"author":1,"featured_media":63503,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"Default","format":"standard","meta":{"footnotes":""},"categories":[2,137],"tags":[],"class_list":["post-63502","post","type-post","status-publish","format-standard","has-post-thumbnail","category-featured","category-news"],"_links":{"self":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts\/63502","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/comments?post=63502"}],"version-history":[{"count":0,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts\/63502\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/media\/63503"}],"wp:attachment":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/media?parent=63502"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/categories?post=63502"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/tags?post=63502"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
