Inside Engineering And Working:
Based on the audio system technology we can categories this gadget into two types. The first one uses specially designed conventional speakers and the second one is using Bone Conduction technique.
Convention speaker-based Bluetooth sunglasses are lower in cost with clumsiness. These are bulky, ugly, and heavy. They are like this because when they are integrated with Bluetooth, they transform from sunglasses to electronics. Various chips, speakers, and batteries are stuck into the glasses arms and it makes them cumbersome.
Bone conduction-based Bluetooth sunglasses uses bone conduction transducers or kind of vibrators that transmit sound vibrations to the Cochlea inside the ear. The sound reaches the ears as vibration through the bones and skin. Although it’s is possible that some sound would still escape the vibrator and run into your ears via air by the Eardrums. So, it is safe to say that in this kind of gadget you will receive most of the sound via the vibrations on your cheekbones.
Following electronic units are being used inside Bluetooth sunglasses nowadays:
- Bluetooth board
- Speakers and microphone
- Li-ion batteries
- Bone conduction sensors
