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: 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.

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: A audio speaker includes two parallel magnetically permeable plates and a diaphragm movably supported parallel to and approximately equidistant from the plates by a surround. A magnet assembly is coupled to the two magnetically permeable plates and passes through an opening in the diaphragm. The magnet assembly includes two magnets that are coupled with two like poles adjacent the diaphragm. A voice coil is coupled around the opening in the diaphragm to move the diaphragm when an electrical current flows in the voice coil. A suspension ring may surround a portion of the magnet assembly with a first end sealed to the diaphragm and an opposing second end sealed to one of the two plates to separate a back volume from a front volume. Some embodiments include several magnetic assemblies passing through the diaphragm with a voice coil and a suspension ring for each magnet assembly.
