This is a super basic 2.5 inch speaker holder. The speaker is held in with a friction fit and the whole thing is glued to the board with epoxy. This was designed as part of my new rocket controller as the controller has a Arduino voice module and talks to the user. It was a super quick and basic design as it serves one simple purpose and will not be seen as it is under the panel with all the wiring.
