Technical support against the bone conduction glasses developed by TDK Corporation
Technical support against the bone conduction glasses developed by TDK corporation
We performed R&D support of acoustic part of AR (Augmented Reality) glasses developed by TDK Corporation.
We suppose that AR glasses becomes main streaming as next generation interface of the smartwatch such as Apple Watch in the future and focus on the bone conduction system that is appropriate for the glasses type wearable device such as AR glasses and does not block the ear.
In R&D of the bone conduction device that is the base of R&D support to TDK, we succeeded downsizing and thinning.
Further, we suggested special mechanism that can surely fit to heads of many users and developed smart bone conduction glasses that does not let them feel mounting stress with TDK.
In addition, we are concerned with sound leak in the bone conduction system; however, we attempted to suppress sound leak by using our knowledge of sound and vibration technologies.

Biomimetics diaphragm
“Biomimetics” means applying structure and element which exist in the natural world to industrial products to solve complicated phenomena.
For the purpose of “coexisting of light weight and high rigidity” and “resonance dispersion” and realizing these, we considered applying structures and configurations of creatures which survive the natural world to a speaker diaphragm shape.
Shape to which “wing vein structure” and “three-dimensional structure of a shell” are applied is applied to a speaker diaphragm.
