Abstract: A balanced armature receiver includes a gas permeable barrier located on a portion of the receiver defining a back volume to provide barometric relief. The barrier can be located in a wall portion or diaphragm of the receiver to vent the back volume to an exterior of the receiver directly, via a front volume, or via a nozzle. The gas permeable barrier is impermeable to liquid infiltration and can be configured to influence the low frequency response of the receiver.

Abstract: An acoustic device that is configured to be disposed at least partially within an ear includes a hard inner sleeve, a soft or flexible outer sleeve, a speaker, a microphone, and a microphone chamber. The outer sleeve includes a first channel and a second channel. The first channel extends through the soft outer sleeve. A portion of the second channel is open and not surrounded by the hard inner sleeve on an outer surface of the hard outer sleeve. The soft outer sleeve at least partially surrounds the hard inner sleeve. The soft outer sleeve covers the portion of the second channel that is open to form an enclosed channel. The speaker is in communication with the first channel. The microphone chamber communicating with a microphone, and the microphone chamber is also in communication with the second channel via a port.

Abstract: An acoustic apparatus includes a top assembly and a bottom assembly. The bottom assembly is coupled to the top assembly to form an overall assembly. A diaphragm assembly is disposed in the overall assembly so as to separate the overall assembly into a front volume and a back volume. The diaphragm assembly includes a frame and the frame has a first end, a second end, and a middle portion that is disposed between the first end and the second end. The first end and the second end are not in the same plane as the middle portion. The first end is coupled to the bottom assembly and the second end is coupled to the top assembly.
