There is research on ultrasound devices which do what you're asking. Designed to work as short-medium term contraceptives[0]. That isn't how smartphones kill sperm however, just as an aside for getting the same-ish results.

- nickpsecurity 11y agoThanks for that link. Interesting. There's also the evidence... which needs more corroboration to be sure... that heat above a certain temperature kills them or weakens them. Small scale experiments and survey of blast-furnace workers provided evidence for it. With both, the fertility went back to normal I think a few months after they left the environment where they were overheated. So, initial evidence for sperm-killing heat to be a safe and effective contraceptive. Doesn't feel as bad as you'd think, either.
