Underwater communication using sensing fusion

Abstract

Underwater communication using sensing fusion can include one or more electronic devices. The electronic device can include a housing defining an internal volume. The electronic device can include a speaker sealed to the housing and tuned for water use (e.g., to produce/detect audible and/or sonar frequency noise underwater). The speaker can include a diaphragm configured to resonate at one or more frequencies underwater. The electronic device can include a pressure compensator associated with the speaker to compensate for hydrostatic pressure acting on the diaphragm. The speaker can include a water permeable membrane to equalize pressure underwater within the speaker, while still maintaining a seal with the housing. The speaker can include multiple seals to prevent water ingress to the internal volume. The electronic device can include another speaker for land communication (e.g., to produce/detect audible noise on land).
