A device and method controlling a speaker to emit a sound to protect a microphone is provided. An example device: determines, using a motion detector, when a drop is occurring. The example device, in response to determining that a drop is occurring: controls a speaker of the example device to emit a sound according to one or more predetermined drop parameters, the sound to apply an acoustic pressure at a membrane of the MEMS microphone of the example device to reduce a deflection thereof that results due to one or more of the drop and an impact which ends the drop.

Systems and methods for verifying sealing integrity in a portable electronic device. One method includes raising, with an electronic processor, an internal temperature of the portable electronic device. The method includes, when the internal temperature exceeds a threshold, determining whether a vent port of the portable electronic device is closed. The method includes, when the vent port is closed, receiving, from a pressure sensor, a first internal pressure for the portable electronic device. The method includes, after a cool down period has elapsed, receiving, from the pressure sensor, a second internal pressure for the portable electronic device. The method includes determining, based on the first and second internal pressures, a pressure drop rate. The method includes determining a sealing integrity indication based on the pressure drop rate. The method includes providing a test result output based on the sealing integrity indication.

A vehicle adapter configured to be mounted to a vehicle. The vehicle adapter includes a body sized and shaped to receive and hold a portable communications device, the body including a surface configured to press against the portable communications device. The vehicle adapter further includes a cooling system coupled to the body, the cooling system including a conduit configured to deliver a coolant to an internal channel of the portable communications device. The conduit defines a projection sized and shaped to press against and open a valve on the portable communications device when the portable communications device is received into the vehicle adapter.
