      You don’t need a chip in a vibration circuit. Hell a potentiometer is more than sufficient to give you different levels of vibration

        I don’t know why I’m replying this deep to play devils advocate for some stupid knife, but I could see a situation where you haven’t completed the research on optimal frequency and ship it out while that’s ongoing. Maybe the window of optimal frequency is narrow enough, or unknown enough, that it’d be difficult to calibrate a potentiometer such that the end user could find that ideal point.
