Bluetooth Mic

[Jayz99]

Hi
I'am trying to build a Bluetooth mic that I can connect with my Bluetooth speaker.
Doing this to help my mom with her teaching in class, so I'm looking to make a small mic with a Bluetooth module that can be hand-held which connects to the speaker to give a louder output.
If someone can help me with the list of components I'd need and how I should go about doing this I'd greatly appreciate it.
Cheers.

Hi , jayz99
there are different commercial bluetooth speaker devices that you can use to your application. You don't spend many money to it. This system use one power small box of 10 Watt about. If you want more power speaker, you may connect to the output and amplify it.

I sorry you for my english but i am italyen and I'm learning it

The microphone should be able to receive the speech audio, amplify it and transmit it via Bluetooth to the speaker. I'm looking to make the microphone as small as possible

ok, there are many devices low cost that do it . Build a bluetooth system is impossible. You should search one bluetooth module that make it . For this reason is convenient to buy one microphone with inside this broadcast system. In reception you have as system as broadcast. You have to buy one low power module TX&RX which low cost, and amplify the reception module speaker output with amplifier

If the microphone can hear the speaker then you will have acoustical feedback howling as the sounds go around and around and around and around and around ....

but in this case there is no problem, because microphone and speaker there aren't near.

The Swiss company Phonak that make my hearing aids make a Roger Pen that is a Bluetooth wireless mic.

how many money ?

how many money ?

The cost of hearing aid products does not matter here in Canada because money grows on trees and you just need to pick it off the tree or from the ground under each tree. I phoned my audiologist and they are thinking about how much profit they can make if I buy a Roger Pen Bluetooth wireless mic and they will phone me back with the price.
I think my government will pay some of the cost.

Hey , thanks for the reply , but what if the mic and the speaker are acoustically isolated could I then transmit the audio without any hassle to the speaker??

I just checked the Roger pen out, what are the components I'd need to make one such device myself ??

Have you considered an off-the-shelf solution; a radio mic such as is used by actors/performers on stage? Some may not be Bluetooth, but is that important?
I doubt you'll be able to build one yourself cheaper than the numerous offerings on Ebay etc.

 

[giova241018]

Of course, however in canada the money grow on trees.
jaz99 , do you live in canada ?

Different rooms with the door closed between them or record the mic then turn it off during a playback.
