Google Glass applies bone-streaming technology

Google has confirmed the use of bone transmission technology for the Google Glass, eyeglasses help users can replace most tasks on the computer. With this technology, no one but the user themselves can hear the message from the device.

An internal source said the device would contact the mastoid area behind the ear, which would direct the sound to the middle ear. That means that all the audio that comes out, from the message alert, Google+ notifications to all kinds of notifications, is directed to the ears of the user, completely inaudible to the people around him. while still maintaining sound quality in a high noise environment.

True-bodied sound transmission has been applied to a number of previous audio devices, from stereo headphones to Bluetooth headsets, such as the Jawbone headset, to direct the vibration of the sound through the cheekbones. , thereby eliminating other background noise. Not only does it perform well in a noisy environment, it also frees users from entangled earbuds.

Google has not released specific hardware information about the sound of this device. In fact, the specs that Google has made available today are likely to change in the future as Google improves its design before launching Explorer for next year. Earlier it was reported that the device was fitted with a small speaker. However, such a loudspeaker will certainly bring about many troubles. For example, to increase or decrease the volume, users will have to continuously adjust the key press on the glasses, unless the volume level is adjusted automatically. Or the device can cause distraction to the people around if the loudspeaker volume is too loud. Meanwhile, some notifications or calls to users require privacy, security.

The sound quality of the sonic transmission technology seems less lively than the traditional headphones, but the outstanding advantages of this technology far outweigh its disadvantages. So it is very likely that the rectangular part of the glass in the Google image published in May was the transmission of bone through the device.
