After testing bone conduction headphone 1.0, I had an issue which the device itself was not stable on user’s head because of the shape that I designed in Fusion 360. However, I got a hint from one of my friend. Why do not you put your prototype onto glasses? I was shocked at what I have not even thought of such a simple solution. After all, I started working on new project called Bone Conduction Sunglasses 2.0. While I am soldering new thing, one of my teachers of electrical engineering recommended me to exhibit my prototype in Maker Faire Bay Area 2017.
I did not expect the prototype accepted, but I got accepted! Therefore, I would be able to introduce my prototype in public. Thank you for everyone involved it, and Maker Faire!
There are two transducers which generate some vibrations based on the audio input from 3.5mm headphone jack.
Basically, these transducers that I am using on the bone conduction sunglasses are called surface transducers. What the surface transducers do is to vibrate any object to make sounds. As you can see on this video, sounds go outside. This is something I need to fix for next prototype.
In Maker Faire
There was a faire for makers from May 19 to 21. I also exhibit my bone conduction sunglasses in my booth. I had a desktop to explain what bone conduction is and how it works with an image.
While I was exhibiting my prototype, I met 9 deaf people. These people gave me really good feedback after they tried. In addition, I got 10 times better result than I expected. Here is the result that I got through the Maker Faire. 8 of them could hear sounds through my device. One man who had an issue of Cochlea could not hear sounds. What I got from them is sounds through the bone conduction was better than some hearing aids that they are using.
After all, I have come up with an idea to next step. I might be able to exhibit the Bone Conduction 2.1 in upcoming mini Maker Faire in San Jose. See you there!
