A microphone mount arranged to receive a microphone (MC), the microphone mount comprising an inner tube (T1) forming an inner cavity (CI) with an opening (OP11) arranged to receive a microphone for capturing sound in the inner cavity (CI) of the inner tube (T1), and with one or more openings (OP12) arranged to allow acoustic waves to enter the inner cavity (CI). An outer tube (T2) forming an inner cavity (C2) with first and second ends having an openings (OP21, OP22). The inner tube (T1) is arranged in the inner cavity (C2) of the outer tube (T2). A sound reflecting surface (R) is arranged at a distance from the second end of the outer tube (T2) so as to reflect incoming sound waves into the inner cavity of the outer tube (T2). Such microphone mount can provide a substantial acoustical amplification of sound in the frequency range 4-10 kHz, to allow clear voice recordings even if hidden behind a person's clothes, such as hidden behind a tie. This allows applications such as high quality recording of voice with hidden microphone during film recordings.

In some embodiments, the disclosed subject matter involves a system and method relating to using an ambient capture device including a fisheye camera and a microphone array to capture audio and video in an environment, for use in an artificial intelligence (Al) application. The device with fisheye camera may provide approximately a 360 audio and video view, at relatively low cost. An embodiment may utilize a speech and vision fusion model component. The speech and vision fusion model may be trained using deep learning to combine features from many different sources, including available sensor data from the capture device. A long short term memory (LSTM) model may inter or identify features such as, but not limited to: audio direction; vision detection and tracking; voice signature; facial signature; gesture recognition; and object identification. The fusion processing may be performed by a cloud server, enabling the capture device to remain less complex.

A single enclosure multi-channel loudspeaker product 100 uses a novel signal processing system and method to achieve a surprisingly effective psycho-acoustically expanded image breadth by inter-aural crosstalk cancellation, in a manner which relies on a new method for cancellation of apparent sources of inter-aural crosstalk. In the commonly owned Polk SDA (prior art) method, the optimal distance between stereo pair main and effect (SDA) loudspeakers was required to be substantially equal to the ear-to-ear width of a typical user's head. Compact SDA speaker system 100 employs digital signal processing generating selected time delays to acoustically simulate the optimal placement of an effects transducer relative to its main transducer for a physically compact configuration having each side's main transducer (e.g., 108LMS) spaced at less than 5.5 inches from the side's corresponding SDA (or effects) transducer (e.g., 108LSS), and this permits the system enclosure to be surprisingly compact, (e.g., width of as little as 341.2 mm).

A surface mount package for a micro-electro-mechanical system (MEMS) microphone die is disclosed. The surface mount package features a substrate with metal pads for surface mounting the package to a device's printed circuit board and for making electrical connections between the microphone package and the device's circuit board. The surface mount microphone package has a cover, and the MEMS microphone die is substrate-mounted and acoustically coupled to an acoustic port provided in the surface mount package. The substrate and the cover are joined together to form the MEMS microphone, and the substrate and cover cooperate to form an acoustic chamber for the substrate-mounted MEMS microphone die.

The present disclosure relates to microphones and electronic devices having the same. A microphone may include a housing for receiving vibration signals; a converting component inside the housing for converting the vibration signals into electrical signals, and a processing circuit for processing the electrical signals. The converting component may include a transducer and at least one damping film attached to the transducer.

The present invention relates generally to microphone mounts and more particularly to an isolation mount for a microphone having an address axis. The isolation mount may include a base configured to attach to an object, a mounting assembly adapted to securely receive the microphone, and a suspension element extending between the base and the mounting assembly. The suspension element may include a first end affixed to the base, a second end affixed to the mounting assembly and a rolling spring extending therebetween, wherein the rolling spring is arranged to form an arc having an opening substantially aligned to the address axis of the microphone. Advantageously, the isolation mount may be configured to have a lowered resonant frequency, to provide a high level of compliance in at least one direction, and to provide a greater degree of energy absorption.

An isolation device (10) comprising a pad (10) having one or more layers of metallic foil (20) and one or more layers of polymer (30), the adjacent layers alternating between metallic foil (20) and polymer (30).

A shotgun microphone unit which includes a housing, a microphone capsule, a shotgun tube having a longitudinal axis, and a shotgun mounting for mounting the shotgun tube with the microphone capsule within the housing. The shotgun mounting has an axial and a radial mounting, wherein the axial mounting is softer than the radial mounting.

A packaged microphone has a lid structure with an inner surface having a concavity, and a microphone die secured within the concavity. The packaged microphone also has a substrate coupled with the lid structure to form a package having an interior volume containing the microphone die. The substrate is electrically connected with the microphone die. In addition, the packaged microphone also has aperture formed through the package, and a seal proximate to the microphone die. The seal acoustically seals the microphone and the aperture to form a front volume and a back volume within the interior volume. The aperture is in acoustic communication with the front volume.

An apparatus for sound detection, sound localization and beam forming comprises a display and a plurality of microphone stacks, wherein the display surrounds each microphone stack in lateral directions. The apparatus further comprises a plurality of elastic connectors, wherein each elastic connector surrounds one respective microphone stack in lateral direction and mechanically connects the respective microphone stack with the display. Each microphone stack further comprises a microelectromechanical transducer array, the transducer array comprising a plurality of membranes, in particular nano-membranes, and corresponding integrated back-volumes, the back-volumes being arranged under the membranes. An optical reading device is configured to separately detect the displacement of each membrane.
