Bone conduction is the transmission of sound vibrations to the inner ear (cochlea) bones of the skull, which allows you to perceive sound without blocking the ear canal. Even more simply put: it’s sound that is delivered directly to the inner ear without needing to pass through the eardrum. Think of bone conduction as a shortcut to hearing sound. Have you ever plugged your ears and sang a song, but wondered how you can still hear the tune? Or heard the sounds generated from brushing your teeth or eating potato chips? That’s bone conduction at its finest, and, along with more commonly used air conduction, your ears have been transmitting sound that way all along! Unlike traditional in-ear or on-ear headphones that utilize air conduction, Shokz has mastered the natural phenomenon of bone conduction by adapting it to consumer electronics, and it’s now the secret behind the success of our open-ear product line. Here’s how we’ve harnessed bone conduction technology to work for our products: 1. Audio Enters The Transducer Every Shokz audio device features two transducers on either side. These transducers, positioned near the cheekbone, work to convert audio signals into mechanical energy (vibrations) which is then sent to your cheekbones. 2. Titanium Makes Conduction Seamless The use of titanium in the frame of all Shokz products is not only because of its lightweight and flexible properties, but also because titanium is an ideal metal for properly and efficiently conducting sound waves. 3. Vibrations Are Converted Into Audible Sound Advances in bone conduction technology have enabled us to create devices that minimize the sensation of vibrations on the temple while still retaining high-quality sound.
