A microphone includes a housing. The microphone includes a windscreen coupled with the housing. The windscreen and the housing define a central volume. The microphone includes an audio module within the central volume. The audio module includes a receiver capsule, a carrier unit coupled with the receiver capsule, and a counterweight coupled with the carrier unit. The microphone includes a suspension element that is coupled with the housing and carrier unit to suspend the audio module within the central volume. The suspension element includes an inner body that contacts the carrier unit. The suspension element includes first and second flanges extending outward from the inner body. The first and second flange are fixedly coupled with the housing. A cross-section of the first and second flange includes an arched region that extends at least partially to an inner wall of the housing. The arched regions are oriented in opposite directions.

Microphone suspension system

A microphone system includes a microphone and a pre-amplification conditioning circuit configured within a housing and comprising a pair of matched JFETs configured in a differential pair with common-source configuration and, when biased, are operable to receive and amplify the differential microphone output signal. The microphone further includes a pair of BJTs configured as a complimentary feedback transistor pair with each of the pair of BJTs coupled in parallel to a corresponding one of the pair of matched JFETs, and a current sink coupled to the matched JFETs and corresponding emitter electrodes of the BJTs and operable to maintain a fixed total direct current through each of the matched JFETs and BJTs, which reduces the JFETs corresponding electrical load, reduces signal noise, and increases a maximum amplified microphone output signal level at the drains of the matched JFETs.

A microphone capsule assembly includes a first microphone capsule oriented to face a first direction that is parallel to a first plane, a second microphone capsule oriented to face in a direction opposite to the first direction, where a front face of the second microphone capsule is spaced a distance from a front face of the first microphone capsule in the first direction, a third microphone capsule oriented to face in a second direction that is at a first acute angle to the first direction when measured parallel to the first plane, and a fourth microphone capsule oriented to face in a third direction that is at a second acute angle to the first direction when measured parallel to the first plane, where the third and fourth microphone capsules are spaced a distance from the front face of the first microphone capsule in the first direction.

Microphone array assembly

Ambient sound is converted into digital signals. A processor performs active noise cancellation and/or a transformation operation that is distinct from the active noise cancellation on the digital signals. The active noise cancellation and the transformation operation transform the digital signals into modified digital signals. The modified digital signals are converted into modified analog signals. The modified analog signals are outputted as audio waves. An interior microphone is configured to output an output signal to the processor in response to receiving the modified analog signals. In response to receiving the output signal from the interior microphone, the processor is configured to determine whether the modified digital signals produce desired audio waves.

Real-time audio processing of ambient sound

There is disclosed a noise reducing headphone including a headphone housing, a microphone generate an ambient audio signal representative of ambient noise, a processor to generate an anti-sound signal based on the ambient audio signal. A first speaker is disposed within the headphone housing to convert the anti-sound signal into anti-sound. A second speaker is disposed within the headphone housing to convert an audio input signal into high fidelity sound. At least one characteristic of the second speaker is different from a corresponding characteristic of the first speaker.

An earpiece for real-time audio processing of ambient sound includes an ear bud that provides passive noise attenuation to the earpiece such that exterior ambient sound is substantially reduced within an ear of a wearer, an exterior microphone that receives ambient sound and converts the received ambient sound into analog electrical signals, and an analog-to-digital converter that converts the analog electrical signals into digital signals representative of the ambient sounds. The earpiece further includes a digital signal processor that performs a transformation operation on the digital signals according to instructions received from a mobile device, the transformation operation transforms the digital signals into modified digital signals, a digital-to-analog converter that converts the modified digital signals into modified analog electrical signals, and a speaker that outputs the modified analog electrical signals as audio waves.

Non-occluding active noise suppression apparatus and methods are disclosed. A housing includes an inlet to admit ambient sound and an outlet to output personal sound to the ear of a user. An acoustic path and an electronic path are provided from the inlet to the outlet within the housing. For a predetermined frequency range, a phase difference between the acoustic path and the electronic path is substantially 180 degrees.

Apparatus and method for non-occluded active noise shaping

A sensor system includes a touch screen and a force sensor. The touch screen has a first and second surface and detects a first surface touch and converts it to data indicative of an X, Y coordinate position upon the touch screen first surface. The force sensor contacts the touch screen second surface and substantially extends around the perimeter of the touch screen second surface. The force sensor measures the force exerted by the first surface touch in the form of force data.
