Abstract
An electronic device may include a printed circuit board and a speaker box defining an acoustic volume between spaced apart first and second speaker box walls with the first speaker box wall being between the second speaker box wall and the printed circuit board. A loudspeaker may be coupled to the first speaker box wall, and the loudspeaker may include an acoustic actuator that is configured to generate displacements in response to an electrical signal applied thereto. The loudspeaker may further include a speaker membrane that is mechanically coupled to the acoustic actuator and that is configured to deflect in directions toward and away from the second speaker box wall responsive to displacements of the acoustic actuator. Related assemblies and methods are also discussed.
