An earphone comprising: an earphone housing having a cap portion and a body portion that interlock with one another to enclose a driver, the driver having a front face that outputs sound waves and a back face opposite the front face, the cap portion defines a first chamber coupled to the front face of the driver and the body portion defines a second chamber coupled to the back face of the driver, a first opening formed through the cap portion; a first port and a second port formed through the body portion and open to a surrounding environment; and a mesh coupled to the first opening, the first port or the second port.

Earphone having a controlled acoustic leak port

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.

Audio speaker with back volume containing adsorptive material

An audio speaker having an adsorptive insert in a speaker back volume, is disclosed. More particularly, an embodiment includes an adsorptive insert having a rigid open-pore body formed by bonded adsorptive particles. The rigid open-pore body includes interconnected macropores that transport air from the speaker back volume to adsorptive micropores in the bonded adsorptive particles during sound generation. Other embodiments are also described and claimed.

Audio speaker having a rigid adsorptive insert

An earphone comprising an earphone housing having a wall comprising (1) a front side that joins (2) an end portion in which a primary sound output opening is formed, which joins (3) a face portion in which a secondary output opening is formed, which joins (4) a back side which joins the front side and encloses a driver, wherein the primary output opening is dimensioned to output sound generated by a diaphragm of the driver contained within the earphone housing into the ear and the secondary output opening is dimensioned to vent the ear to a surrounding environment, and wherein the primary output opening and the secondary output opening face different directions.

Ultrasonic ranging for mobile devices is disclosed. A mobile device using ultrasonic ranging can include an ultrasound transmitter capable of emitting an ultrasound signal for detection by a proximate device and an ultrasound receiver capable of receiving an ultrasound signal from the proximate device. The mobile device can then use a time lapse associated with one or both of these ultrasound signals to find a range to the proximate device.

Ultrasound ranging for mobile devices

A speaker assembly including a frame and a magnet assembly positioned within the frame. The magnet assembly may include a magnet and a top plate. The assembly further including a sound radiating surface suspended over the magnet assembly. The sound radiating surface includes a flexible circuit. A suspension suspending the sound radiating surface over the magnet assembly is further provided. The suspension may be over molded to the sound radiating surface and the frame. A voice coil extends from a bottom side of the sound radiating surface and electrically connects to the flexible circuit.

Speaker with flex circuit acoustic radiator

An audio speaker having a suspension system including a surround to support a diaphragm within a frame and to reduce non-pistonic motion of the diaphragm at several resonant frequencies is disclosed. More particularly, embodiments of the surround include a film that undulates in a peripheral direction around the diaphragm and includes several undulations above and below a radial gap between the diaphragm and the frame. Other embodiments are also described and claimed.

Audio speaker surround geometry for improved pistonic motion

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.

Valve for acoustic port

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.
