SPEAKERLESS AUDIO, NO MORE SPEAKERS IN YOUR CAR

Continental, a brand you might recognise for its automotive tyres, wants to supply its new sound technology to car manufacturers which would eliminate the need for traditional loudspeakers.

The speakerless audio and transducer technology it calls 'Ac2ated Sound', vibrates physical parts of the vehicle, such as an interior door panel,  side glass or windscreen. The technology is not new but to our knowledge hasn't yet been implemented within a vehicle. Check out Nakymatone's invisible speakers that are installed in your walls.

Continental is an OEM for German manufacturers including BMW, Audi and Mercedes. A report in the New York Times recently indicated that Continental could have the technology ready for mass production by 2021.

Its small transducers conduct an electrical signal which vibrates through the panel it is attached to.

Multiple panels of differing physical size are required for full-range sound. For example, the larger and more rigid the panel, the lower the frequency it will produce. It's likely multiple panels throughout the vehicle will be required, and Continental says up to 10 panels will be required for 'premium' sound.

GadgetNET says: There's no indication that this technology will ever outperform traditional loudspeaker design regarding sound quality. The advantage here is in the weight savings and efficiency and as we move to electric vehicles, every gram matters.
