摘要： An acoustic port of acoustic device is covered with a mesh and/or other structure that resists entry of liquid and/or other materials into the acoustic device. Apertures of a housing that are separated by an umbrella section are coupled to the acoustic port such that the umbrella section may cover the acoustic port. In this way, when liquid enters one or more of the apertures, the umbrella section may direct the liquid away from the mesh such that pressure from the liquid upon the mesh may be reduced. As such, potential damage to the mesh and/or internal acoustic device components may be mitigated. In some implementations, the apertures may be covered with an additional mesh. Such additional mesh may further reduce the pressure of entering liquid on the mesh covering the acoustic port of the acoustic device.

摘要： An acoustic module, such as a microphone or speaker module, includes an acoustic membrane that vibrates to produce acoustic waves and an acoustic cavity through which acoustic waves produced by the membrane travel. A liquid removal mechanism removes liquid from the acoustic cavity. Such a liquid removal mechanism may include the acoustic membrane, heating elements, hydrophobic and/or hydrophilic surfaces, and so on. In some cases, the liquid removal mechanism may remove liquid from the acoustic cavity upon connection of the acoustic module and/or an associated electronic device to an external power source.

摘要： An acoustic module is coupled to an acoustic passage. The acoustic module includes an acoustic transducer coupled to a diaphragm. A controller or other circuitry measures an impedance of the acoustic transducer. Based on the impedance, the controller determines whether the impedance indicates that the acoustic passage is blocked. The controller may determine that the acoustic passage is blocked by liquid that is present in the acoustic passage. When the controller determines based on the impedance that liquid is present in the acoustic passage, the controller may drive out, purge, and/or otherwise remove the liquid, such as by using the acoustic transducer to vibrate the diaphragm.

摘要： An electronic device having a composite acoustic membrane to inhibit water ingress and to allow sound transmission, is disclosed. Embodiments include an electroacoustic transducer within an encased space of a casing, and a composite acoustic membrane between the electroacoustic transducer and an acoustic port in the casing. The acoustic membrane may include a nonporous region at least partly covering the acoustic port, and a porous region to vent the electroacoustic transducer volume to the encased space and/or to an environment surrounding the casing. Other embodiments are also described and claimed.

摘要： 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.

摘要： A differential pressure gradient micro-electro-mechanical system (MEMS) microphone for measuring an acoustic characteristic of a loudspeaker. The microphone includes a MEMS microphone housing and a compliant membrane mounted in the MEMS microphone housing, the compliant membrane dividing the MEMS microphone housing into a first chamber and a second chamber. The first chamber includes a primary port open to a first side of the compliant membrane and the second chamber includes a secondary port open to a second side of the compliant membrane, and the primary port and the secondary port are tuned with respect to one another to control a pressure difference between the first side and the second side of the compliant membrane such that at least 10 dB of attenuation is observed in a microphone signal output relative to a microphone having a sealed first or second chamber.
