According to a discovered patent which has been filed by Google, the design of Google’s Glass might include a indirect bone conduction speaker to deliver audio to the wearer.
The indirect bone conduction speaker will vibrate the frame of the eyewear, which will then be passed to the wearer via their skull and through the inner ear.
Unlike bone conduction speakers, the indirect method Google might be planning to use vibrates the frame rather than your bones, Google called this new method “indirect”. Using the indirect method rather than bone conduction, the frames act as a transport mechanism which actually brushes up against your face, nose and temples and more as they are worn.
The patent, named “Wearable Computing Device with Indirect Bone-Conduction Speaker“, was first filed on October 10, 2011, but came into the public eye yesterday on January 24th, 2013.
“A wearable-computing system comprising: one or more optical elements; a support structure comprising a front section and at least one side section, wherein the support structure is configured to support the one or more optical elements; an audio interface configured to receive an audio signal; and at least one vibration transducer located on the at least one side section, wherein the at least one vibration transducer is configured to vibrate the at least one side section based on the audio signal; wherein the support structure is configured such that when worn, a first portion of the at least one side section has an inner wall that contacts the wearer so as to vibrationally couple to a bone structure of the wearer; wherein the vibration transducer is located on a second portion of the at least one side section having an inner wall that does not contact the wearer, such that when the support structure is worn, the vibration transducer vibrates the support structure without directly vibrating a wearer.”
