  • Patent number: 11146890
    Abstract: The present disclosure relates to a method for simultaneously operating a loudspeaker assembly in a loudspeaker function and in a microphone function. The loudspeaker assembly comprises a coil, which is movably mounted in the magnetic field of a magnet, and a diaphragm, which is mechanically coupled to the coil, wherein the magnet produces a magnetic flux density (B), the coil, has an effective length in the magnetic field, and the diaphragm has an area (A). In order to determine a first transfer function ZM, a first calibration state is set, in which an external sound pressure (p) on the diaphragm is equal to zero. In order to determine a second transfer function ZC, a second calibration state is set, in which movement of the diaphragm is suppressed.

  • Patent number: 11051091
    Abstract: A cleanroom compatible elastomeric cover for an acoustic attachment, such as a diffuser or a director, to a Small Ceiling Speaker System. The present invention provides one elastomeric cover for the otherwise exposed axial acoustic port of a director or the exposed radial acoustic port of a diffuser. The cover further provides a cleanroom seal between the diffuser or the director and the ceiling tile. The diffuser and the director are each acoustic attachments to the enclosed speaker portion of the small ceiling speaker that is above the ceiling tile and supported on the ceiling tile support grid, rather than the tile itself. The portion of the small ceiling speaker that is below the ceiling tile includes a sectionally threaded acoustic channel shell and an acoustic attachment. The cover prevents contaminants from entering the cleanroom though the hole in the ceiling tile through which the acoustic channel shell extends.

  • Patent number: 10015618
    Abstract: Techniques of rendering sound for a listener involve producing, as the amplitude of each of the source driving signals, a sum of two terms: a first term based on a solution s† to the equation b=A·s, and a second term based on a projection of a specified vector ? onto the nullspace of A, ? not being a solution to the equation b=A·s. Along these lines, in one example, the first term is equivalent to a Moore-Penrose pseudoinverse, e.g., AH(AAH)?1·b. In general, any solution to the equation b=A·s is satisfactory. The specified vector that is projected onto the nullspace of A is defined to reduce the coherence of the net sound field. Advantageously, the resulting operator is both linear time-invariant and idempotent so that the sound field may be faithfully reproduce both inside the RSF and at a sufficient range outside the RSF to cover a human head.

  • Patent number: 9510076
    Abstract: Disclosed is a waterproof earphone structure including a main body with a rear cavity and a front cavity for installing a waterproof module and a shielding module respectively, and a speaker body installed in the main body. The waterproof module includes first and second waterproof elements installed in the rear and front cavities of the main body respectively. This structure not just allows users to sense external sounds only, but also improves low-frequency noise interference and water-resistance. Since the first and second waterproof elements are formed with pores having a diameter smaller than 0.6 mm and arranged apart from one another, external low-frequency noises are suppressed. Further, the effect of surface tension prevents water from entering into waterproof devices or soaking the interior of the earphone. Users enjoy good sound quality since the sound is transmitted through the pores. In addition, the shielding module provides an anti-dust effect.

  • Patent number: 9451348
    Abstract: An electronic device housing includes an outer casing, a microphone, and a recess in the outer casing proximate to the microphone. A base of the recess has a first adhesive portion and an adjacent first non-adhesive portion, and a hole is defined in the first non-adhesive portion and the recess. The hole and the recess define an acoustic pathway for sound external to the outer casing to reach the microphone. The first adhesive portion and the first non-adhesive portion have different shapes.

  • Patent number: 9426560
    Abstract: Disclosed herein is a waterproof case for protecting electronic devices. The waterproof case includes a flexible waterproof bag attached to a rigid lid that can be opened to allow electronic devices to pass into the bag. When closed, the lid forms a watertight seal that protects the inside of the bag from ingress of water. The lid can include a pass-through jack which allows a user to connect an electronic device, such as an audio device, to an output through the lid. The case may also be incorporated into a flexible attachment system, such as an armband or swimbelt. Methods of connecting an electronic device to an electronic output, such as an audio output, through a waterproof case are also provided.

  • Patent number: 9374635
    Abstract: This document describes methods and apparatus for reducing a magnetic field emitted by an earpiece assembly from extending substantially outside a device associated with the earpiece assembly. Where the earpiece assembly is susceptible to ingress of magnetically attractable particles into the earpiece assembly such a reduction can prolong an operational life of the earpiece assembly. By insert molding magnetically permeable materials throughout an enclosure that surrounds and supports a permanent magnet of the earpiece assembly, a portion of a magnetic field emanating from the permanent magnet that extends outside the device can be substantially reduced or redirected so that the magnetic field ceases to draw the magnetically attractable particles into the earpiece assembly.

  • Patent number: 9357299
    Abstract: A device comprises a housing, an acoustic component coupled to an exterior of the device through an acoustic passage in the housing, and an actuated mechanism operable to close the acoustic passage between the acoustic component and the housing. The actuated mechanism is operable to close the acoustic passage in response to a control signal, where the control signal is indicative of a pressure differential transmittable from the exterior of the device through the acoustic passage to the acoustic component.

  • Patent number: 9326080
    Abstract: Methods and systems are taught for testing microphone packages—including measuring non-acoustic noise for the package. A package positioner holds a microphone package such that an acoustic input port of the microphone package is aligned with a plug. An actuator moves the plug relative to the microphone package between a first position—where the plug does not obstruct the acoustic input port of the microphone package—and a second position—where the plug obstructs the acoustic input port and restricts acoustic pressures from entering the microphone package through the acoustic input port. A controller monitors an output of the microphone package and identifies the output as indicative of isolated non-acoustic noise when the plug is in the second position.
