Hand Microphone for Airbus A320

Updated: Nov 24

Lately I have been digging deep into the cockpit communications and intercomm system. Currently I am using JeeHell's intercomm system which is an acceptable solution with some improvements to be implemented in the future.. hopefully... In this context I wanted to have realistic looking handheld mike both for the captains and first officers side. So I did a 3D CAD design first to get a real fealing of the hand held mike and then performed 3D printed from PLA material for the actual physical mike. I will mention about the electronics and interfacing as well.


The original handheld microphone in an Airbus A320 cockpit looks like ;

I could not find anywhere over the internet dimensional information on this, so I had to fully improvise as always ; did an 3D CAD design, 3 parts (the main body, top part and the top cap). The dimensions I used for my hand held mikes are as follows;

The top part 3D modeled looks like this, I have installed an electret type condenser microphone module in this piece.

The assembly of all pieces looks like (in 3D design enviroment) ;

The hang this hand held microphone on the side console, a special type holder was designed as below;

The parts were printed in my 3D printed using PLA material. I find the end results very satisfactory as can be seen below ;

I will also publish a blog entry on how I interfaced this microphone, the push button with the JeeHell FMGS intercom software. So keep an eye on the web site
