Discover the inner workings of a modern wireless speaker system!
Wireless speakers combine the same basic techniques that the first speakers and wireless devices were based upon. So what makes modern wireless speakers stand out?
Well, today’s systems employ a transmission protocol called SKAA – a hi-fi audio standard that uses a portable device as the sound source that can be connected to any wireless gadget with SKAA support. Today, the 2.4GHz radio wavelength is a very crowded frequency as it’s such a high-quality audio band, so SKAA makes use of a patented protocol to avoid conflicts with any other devices.
Of course, speakers themselves have been refined in many ways over the years too. Alloy tweeters are now geometrically designed using computer software to find the optimum shape, then coated with ceramic and anodized with gold: this improves high-frequency sound output.
Elsewhere, the main drivers are made out of the same light yet rigid material originally developed for jet engines, which ensures it is highly resistant to flexion, or bending; this also reduces audio distortion at higher audio outputs.
Wireless receiver – The core of the speaker’s communications tech, the SKAA-based receiver delivers audio without noise and dropout.
Gold dome C-CAM – Advanced tweeter modelling moves sound breakup beyond the 35kHz range for clarity that extends way beyond human hearing.
C-CAM driver – The alloy driver cone is coated with an ultra-thin (50-micrometre) layer of ceramic alumina to dissipate heat.
