Abstract: An acoustic transducer includes a housing, which may be a circular cylinder or may have a rectangular cross-section. Two permanent magnets that closely fit the inside of the housing are joined by a linkage having a high magnetic permeability to form a piston that is inserted into the housing. Two pole coils surround the housing with each coil adjacent one of the permanent magnets. The coils are arranged to cause the piston to oscillate within the housing and emit sound waves when coupled to an electrical signal. One end of the housing may be closed except for a barometric leak. A third permanent magnet or a spring may provide a restoring force that centers the piston between the coils when the piston is not subjected to other forces. One of the permanent magnets on the piston may include a vent passage.

Abstract: A portable electronic device having an outer case having a substantially planar face in which a microphone associated acoustic port is formed. The device also has a micro-electro-mechanical system (MEMS) microphone positioned within the outer case, the MEMS microphone having a diaphragm facing the microphone associated acoustic port. An acoustic mesh is positioned between the front face of the outer case and the diaphragm, the acoustic mesh having a non-linear acoustic resistance so as to minimize an effect of an incoming air burst on the diaphragm. Other embodiments are also described and claimed.

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: A micro-electro-mechanical system (MEMS) transducer including an enclosure defining an interior space and having an acoustic port formed through at least one side of the enclosure. The transducer further including a compliant member positioned within the interior space and acoustically coupled to the acoustic port, the compliant member being configured to vibrate in response to an acoustic input. A back plate is further positioned within the interior space, the back plate being positioned along one side of the compliant member in a fixed position. A filter is positioned between the compliant member and the acoustic port, and the filter includes a plurality of axially oriented pathways and a plurality of laterally oriented pathways which are acoustically interconnected and dimensioned to prevent passage of a particle from the acoustic port to the compliant member.

Abstract: A mobile multi-function device that includes a speaker, two or more microphones, and a beamformer processor is described. The beamformer processor uses the microphones to perform beamforming operations. One of the microphones shares a receiver acoustic opening with the speaker while the other microphone uses a separate acoustic opening. The receiver acoustic opening may be an earpiece opening that is held to the ear of a user while conducting a phone call with the device and provides acoustic input and output paths for the microphone and the speaker, respectively.

Abstract: 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.
