Definitely, a special interface would let us use less volume due to its efficency, but a simple (and powerfull) loudspeaker preferrably covering low frequencies would do as well. I simply take my 6-inch PC subwoofer and put it on my knee and then rotate, trying to find some position where vibration penetrates most inside the joint. As a rule, its some of its rear plastik parts. The bigger the speaker, the better. But be careful though, as vibration can kill as well as heal..

But there's always a risk when exploring new technologies. Today I've made some tests on myself and my knee has noticed some positive effect..
