A case for a portable electronic device includes an enclosed, elongated space extending within the case from an opening in an interior surface of the case. The opening corresponds to the location of a microphone in the device. The enclosed space is tapered to an increasingly smaller cross-section as it extends away from the opening. A first edge of the enclosed space aligns along most of its length with an exterior surface of the case. A screen covers a second opening in the exterior surface of the case along the first edge of the elongated space and provides an acoustic resistance between the elongated space and air outside the case through the second opening. A gasket located at the first opening couples the elongated space to the microphone of the electronic device.

An image capture device, having: a housing, a lens snout, a front microphone, a top microphone, and an audio processor. The housing has a top and front housing surface. The lens snout protrudes from the front housing surface. The front microphone mounted within or on the front housing surface and below the lens snout. The top microphone mounted within or on a top housing surface in a position biased toward the front housing surface. The audio processor comprises a memory that is configured to store instructions that when executed cause the audio processor to generate an output audio signal. The top microphone is located at a position to receive direct freestream air flow when the housing is positioned in a pitched forward orientation at a pitched forward angle relative to a vertical axis. The front microphone receives turbulent air flow from the lens snout when the housing is positioned in the pitched forward orientation.

A microphone housing is described with a screen for wind noise reduction. One example includes a housing defining a cavity and a surface on one side of the cavity, a mesh of holes through the surface into the cavity, and a microphone mounted inside the cavity.

The specification and drawings present packaging for integrating a microphone into an outdoor luminaire that provides high sensitivity and dynamic range together with being waterproof, resistant to impact and wind noise, environmentally resistant and unobtrusive to passers-by. Various embodiments describe packaging of outdoor luminaire mounted microphones to achieve waterproof and minimized unwanted noise performance, and other desirable features.

Provided is an acoustic transducer including: a semiconductor substrate; a vibrating membrane provided above the semiconductor substrate, including a vibrating electrode; and a fixed membrane provided above the semiconductor substrate, including a fixed electrode, the acoustic transducer detecting a sound wave according to changes in capacitances between the vibrating electrode and the fixed electrode, converting the sound wave into electrical signals, and outputting the electrical signals. At least one of the vibrating electrode and the fixed electrode is divided into a plurality of divided electrodes, and the plurality of divided electrodes outputting the electrical signals.

In an electronic device, at least a portion of a camera cover member is disposed inside a housing. The camera cover member includes a through-hole in fluid communication with the outside of the housing, and is formed to support a camera module disposed inside the housing. A microphone module is disposed inside the housing so as to be adjacent to the camera module, and includes a first circuit board disposed on the camera cover member and a microphone disposed on the first circuit board. A second circuit board is disposed to face the camera cover member with the microphone module therebetween, and includes a contact structure in contact with the first circuit board. The contact structure is configured to electrically connect the first circuit board to the second circuit board and can be disposed between the first circuit board and the second circuit board to surround the microphone.

Earpieces and methods of forming earpieces for radio frequency (RF) mitigation are provided. An earpiece is configured to be inserted in an ear canal. The earpiece includes an insertion element and a sealing section disposed on the insertion element and configured to conform to the ear canal. The sealing section is configured to substantially mitigate radio frequency (RF) transmission and to substantially isolate the ear canal from an ambient environment.

An audio capture device for a submersible camera including a supporting structure to prevent a waterproof membrane from deflecting beyond a point that will cause damage to the membrane. A microphone assembly includes a microphone for detecting ambient sound and generating an electrical signal representing the ambient sound. The microphone assembly is covered by a waterproof membrane to prevent water from reaching the microphone assembly. One or more supporting rings near the waterproof membrane prevents the waterproof membrane from deflecting more than a threshold deflection.

A wireless earphone comprising a housing that defines an interior cavity having an inner surface and an outer surface; an opening extending through the housing from the inner surface to the outer surface; and a mesh assembly disposed over the opening and comprising a permanent assembly coupled to the housing and a replaceable assembly removably coupled to the permanent assembly and comprising a mesh.

A hand gesture control system to be operated via hand gestures to receive a call from a mobile phone includes: a casing; a control unit installed inside the casing; a hand gesture recognition unit installed inside the casing, including an image capturing module and a hand gesture recognition module, wherein the image capturing module captures an image of a hand gesture of a user and transmits to the gesture recognition module for comparison, which feeds back an operation instruction to the control unit corresponding to the comparison; a wireless transmission unit communicates with the mobile phone via a wireless communication protocol for establishing communication between the mobile phone and the control unit; a microphone disposed at an exterior of the casing in order to receive a user's voice; and a loudspeaker disposed at an exterior of the casing in order to output the user's voice from the microphone.
