This is the medical device : http://www.dymedso.ca/site_usa/patient/en/frequencer_v2_easy_to_use.htm
You can hear what it sounds like here : https://www.youtube.com/watch?v=wXbJWYRvxOU
This paper describes how it works (Page 10) : http://www.dymedso.ca/pdf/White%20paper_rev0_Sept20_041.pdf
The above document contains a lot of valuable information and some math regarding how the Frequencer works (page 19).
The device uses sound waves to create vibrations inside the patient's chest to help dislodge thick mucus.
I need a driver that can generate frequencies between 20Hz and 65Hz. It has to be around 6 inches and not too heavy. From the little that I understand about speakers, this seems like a tall order. How can I achieve this?
Thanks for your help.
