Hypophonia Amplification Device

Contest Closed
I have Parkinson's disease. One of the classic symptoms of Parkinson's is hypophonia, a decrease in speech amplitude. My hypophonia is severe and presents a challenge to me in terms of job, family, & friends. I am seeking a small, discreet, and aesthetically pleasing personal amplification device. Here are some criteria.
-The microphone should be sensitive as my hypophonia is severe.I'm not averse to a handheld microphone that I bring to my mouth as needed.
-I would like an on-off switch on the microphone.
-I prefer regular batteries to rechargeable batteries
-The speaker should be small and have volume control. I would like to be able to use it for one-on-one conversation as well as in meetings or when lecturing.
-it would be great if the speaker could be placed somewhere nearish to where the sound naturally comes from, i.e., my mouth. E.g. the collar of the shirt or pinned to the shirt pocket. Attached to the belt is also possible.
-Would be nice if the speaker could be removed and put on the table for meetings
-All three pieces (mic, speaker, amplifier) can be separate so no one is too bulky
Small, discrete, powerful, adjustable volume, aesthetically pleasing, lack of mic/spkr feedback
Don't Wants:
-I have https://www.amazon.com/WinBridge-Rechargeable-Ultralight-Presentations-Etc-Black/dp/B014JJG43E/ref=sr_1_1?ie=UTF8&qid=1494774803&sr=8-1-spons&keywords=winbridge+voice+amplifier&psc=1 and it works reasonably well, but it is big and clunky.
Ask for Sample:
I want you to design it and I want you to build it. $250 prize for the design, then I pay parts & a fair profit to you for building it.
  1. This is a required field, but I have no idea what to put here

Both mic and the speaker are lightweight, both use clip on style so you can wear them on your shirt, suit or other type of clothing. Speaker is easy to use and requires only one AA batery, and it has on one side the volume button and on the other it has a jack port for the microphone. Microphone is made in the same way with a clip on the back to hold it in place while you are speaking. Microphone has an ON/OFF switch, with led light green nad red as to indicate when it is on and when not. Head of the microphone is a very sensitive microphone head as you recomended. Microphone and speaker are conected by the wire provided in the picture, also the speaker can be put on a belt and also on table.

#3 hypophonia amplification device by Manuel Zaragoza
For a look at it go to
and the same microphone connector CAD.
Here the deal what i did different
the dimensions are: height 2.5 inches, Length 2.5 inches, and thickness is .4 inches if you include the clip.
for better dimensions detail look into the pdf for the hypophonia amplification device drawing
The volume control is the + and - signs on the device. and the P sign is for power. the red on the device is for the
microphone connector CAD.
There is a switch as you request for the microphone connector CAD. this switch will turn off and on the sound.
The stl file will allow you to 3d print it out and attempt to assembly it.
You can use the Grundig Mini 400 Shortwave Radio as a guide build the circuit and use the speaker in it.

I base my design off of the sony x11 ultraportable bluetooth speaker
- http://www.bestbuy.com/site/sony-x11-ultraportable-bluetooth-speaker-blue/6604143.p?skuId=6604143&extStoreId=&ref=212&loc=1&ksid=34abc314-af94-45b3-82ea-6b056573dd13&ksprof_id=11&ksaffcode=pg210753&ksdevice=c&lsft=ref:212,loc:2
for me this is as small as it gets if you want quality sound and high volume.
The volume control is the + and - signs on the mini-box device. and the P sign is for power.

There is a switch as you request for the microphone connector CAD. this switch will turn off and on the sound.
i also include a stl file so you can 3d print it out to have a better look at it.
