A piezo speaker pressure sensor that includes a bladder and a piezo speaker element. The bladder abuts the piezo speaker element. A pressure may be sensed from the piezo speaker element proportional to a pressure exerted on the bladder in a direction of the piezo speaker element. The piezo speaker element functions as a speaker when audio signals are received by the piezo speaker element.
