Abstract: An acoustic transducer can have an acoustic diaphragm defining a barometric vent configured to equalize a barometric pressure-gradient across the acoustic diaphragm. Such a barometric vent can be formed by an aperture through the acoustic diaphragm. A gas-permeable vent membrane can be coupled with the acoustic diaphragm and extend across the aperture. The vent membrane can inhibit movement of liquid across the vent membrane. An acoustic-transducer module can include a chassis a chassis configured to mount the acoustic-transducer module to another module, and a suspension system can movably couple the acoustic diaphragm with the chassis. Such an acoustic-transducer module can sealably couple with a housing of a water-resistant electronic device to inhibit a flow of liquid into the housing while providing a water-resistant barometric vent to the housing, as well as an acoustic diaphragm having a sufficient size to meet or exceed selected acoustic-performance targets.

Abstract: A portable electronic device including an enclosure having an enclosure wall that forms an interior chamber. A speaker module is positioned within the interior chamber and includes a speaker and a module wall forming a back volume chamber of the speaker. The back volume chamber includes an acoustic vent port formed through the module wall to acoustically couple the back volume chamber to the interior chamber. The device further including an electromechanical valve for regulating the acoustic coupling of the back volume chamber to the interior chamber. The electromechanical valve is operable to transition between an open configuration in which the acoustic vent port is open to the interior chamber and a closed configuration in which the acoustic vent port is closed off from the interior chamber.

Abstract: An audio speaker having a speaker housing surrounding a back volume that is divided into a rear cavity behind a speaker driver and an adsorption cavity separated from the rear cavity by a permeable partition, is disclosed. More particularly, the adsorption cavity may be defined between the speaker housing and the permeable partition, and may be directly filled with adsorptive particles to adsorb gas during sound generation. The permeable partition may allow the gas to flow between the rear cavity and the adsorption cavity, and may retain the adsorptive particles within the adsorption cavity. Other embodiments are also described and claimed.

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.

The driver has a diaphragm with a front face and a rear face, and a motor to vibrate the diaphragm in accordance with an audio signal. A back volume chamber is positioned behind the driver within the earphone housing. The diaphragm is part of a wall of the back volume chamber. An acoustic mass loading membrane that is part of a wall of the back volume chamber, and that is to vibrate in response to acoustic waves produced by vibration of the diaphragm impinging on a front face of the membrane, is provided. Other embodiments are also described and claimed, including a polymer production process for an elastic material.
