tNEO3P_xxgw, Home made hearing aid at LOW COST under , this device is called hearing aid
it is a prototype model made at home thus, we use mini vibrator motor as a speaker to convert vibration into sound waves
*CONCEPT*
inside our ear we have small bone called “STAPES” that convert sound waves into brain signals
in our model we use this same vibration concept by using vibrator motor .while playing song the vibrator vibrates instead of rotating
when vibrator is placed behind the ears the vibration easily reaches our brain into sound signals thus we can hear audio by simply closing our ears
incase of deaf we can easily hear audios .
