Speaker mount for Skywalker Mini Trampoline

We bought a Skywalker Mini Trampoline for our Grandson. It comes with a speaker that makes sounds when you jump on it. There is nowhere to put the speaker except laying it on the ground underneath. That just wont do.

I designed it to clip over one of the lower support legs (1" diameter pipe).

It slides out easily to change the batteries and allows easy access to the power switch.

Here is a link to the trampoline we bought (no affiliation).
