SpeakUP design with fans attached

I need details of All measurements of All angles in design. I have fans with filtered air circulation, as well as a power box with detailed circuit board (already designed) then a wire to mouth area. Inside the mask @ mouth level a waterproof microphone. The microphone will have 2 thin spikes poking out that is pushed through the mask material, into plugs attached to end of wire leading from power box. There is a speaker set into the power box that has on/off button, volume control, recharge USB, plug in on fans. Both fans & power box are held in place by magnets, attach to any mask & transferable repeatedly to clean masks. The fans are detachable to use only the microphone/speaker/power box parts.
