Abstract
An electronic device includes a microphone coupled to a first substrate, a second substrate defining an acoustic port, and a pressure relief device situated between the first substrate and the second substrate. The pressure relief device includes a bore defining an acoustic duct through which the microphone receives acoustic energy from the acoustic port. The pressure relief device also includes a venting section. The venting section breaches the acoustic duct when a pressure within the acoustic duct exceeds a predefined pressure threshold.
