ABSTRACT:
An automated external defibrillator (AED) having a housing and an openable lid with a water resistant speaker port formed in the housing below the openable lid. A water resistant fabric is attached underneath the speaker port to resist water passing into the interior of the AED while allowing clear sound output from the speaker located beneath the speaker port. A microphone is positioned adjacent to the speaker port in the AED for recording emergency scene ambient activities. This position uses the existing water resistant opening thereby taking advantage of the good sound transmitting properties of the opening for recording purposes and at the same time eliminating the need for an additional cavity in the housing where water could ingress. Positioning the microphone near the speaker also eliminates the need for an additional wiring harness.
