Abstract: An apparatus includes a microphone and a gasket. The microphone includes a base having an inner surface and an outer surface. The inner surface is generally parallel with the outer surface. The base has a port extending from the outer surface to the inner surface. The microphone includes a micro electro mechanical system (MEMS) transducer coupled to the inner surface of the base over the port. The microphone has a cover coupled to the base and the cover encloses the MEMS transducer. The gasket is coupled to the outer surface of the base and forms a channel. The channel has a first end and a second end. The first end communicates with the port of the microphone, and the second end of the channel is generally aligned with an edge of the base.

Abstract: An acoustic apparatus includes a mechanical shell, a first electronic component, a first connector, and a receiver. The mechanical shell is generally cylindrical in shape and forms a cavity, the shell having an inner surface, the inter surface in communication with the cavity. The first electronic component is disposed in the cavity. The first connector includes electrical contacts and is disposed on the inner surface of the shell. A first electrical connection electrically couples the microphone to the first connector. The receiver is disposed in the cavity, and the receiver has a second connector. An electrical connection is formed between the first electronic component and the receiver via the first connector and the second connector. A rotation of the shell causes the electrical contacts to rotate within or with respect to the second connector such that the rotation does not cause the electrical connection between the first connector and the second connector to be broken.

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.
