Glasses with built-in screens, cameras and – most importantly – loudspeakers are appearing on the market. These types of devices allow the user to perform many of same tasks as they would on a portable device (phone/tablet) while having hands free for other tasks. These pages specifically deal with the audio part of the smart glasses, where loudspeakers are placed in the temples as close to the ear entrance as possible in order to deliver the best sound. The speakers’ job is to direct sound waves towards the user’s ear while the ears remains unoccluded, allowing the user to hear the surroundings while listening to audio at the same time. This is where Ole Wolff’s expertise in maximizing sound performance from tiny enclosures can make a notable difference.
