How to assemble together and pass sound through in one system

As you may know, I'm researching around parabolic speakers and did a survey around my first prototype (see https://www.diyaudio.com/forums/planars-and-exotics/352353-project-parabolic-speaker.html).
As I'm going deeper in the survey, people ask to be able to mount the parabolic speaker easily on various supports (floor support, desk support, hanging, etc.).


As for lights there are light bulbs that you can hold & plug to electricity in one system (screw or bayonet), is there such system for audio that fix pieces together and ensure sound signal is passing through?


If not, is there any usage that you would think it could be useful as well (so that I design it accordingly)?
 
Thanks, that's a very useful piece of information.
I feel like it's convenient to prevent any accidental unplug but not suitable to mechanically hold something like a light bulb is hold.


My parabolic speaker is beyond 500g. 😀



Any other idea?
