+14db project

For the deaf-blind, real-time communication methods are limited to tactile methods such as "handwriting," "finger sign language," and "finger braille." 
This project attempts to provide another tactile communication method that does not rely on either hearing or vision by converting Morse telegraphy, which is both a voice communication and a primitive digital communication, into low-frequency vibrations. Since it can be transmitted via electric communication, it enables remote and one-to-many communication that was difficult with conventional communication methods. Furthermore, if he/she obtains an amateur radio license, he/she can use a vibration converter and a vertical key to achieve completely barrier-free communication with general amateur radio stations on the telegraph band. (= We can communicate without being conscious of hearing and visual impairments each other.)  My goal is to follow that up and fully utilize the "universal design" of Morse telegraphy.
