Publication number: 20230379626Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may operate the speaker at or near one or more resonance frequencies of the speaker and/or the electronic device. This can allow the electronic device to efficiently eject an occlusion when the speaker is occluded by a fluid or other debris. For example, the electronic device may determine a resonance frequency by obtaining one or more electrical characteristics of an electronic component while the speaker is occluded, determine the resonance frequency based on the obtained electrical characteristic(s), and operate the speaker at a frequency that is based on the resonance frequency to eject the occlusion.Type: ApplicationFiled: April 19, 2023Publication date: November 23, 2023Inventors: Yang LIU, Ashwat Kandasamy AMIRTHALINGAM, Onur I. ILKORUR, Thomas M. JENSEN, Oliver LEONHARDT, David W. ROBISON, Teemu P. SIPILA

Publication number: 20220360886Abstract: Aspects of the subject technology relate to electronic devices having speakers with resonators, such as Helmholtz resonators, acoustically coupled to the front volume of the speaker. A speaker module for an electronic device may include multiple resonators, including a first resonator that is acoustically separate from, and at least partially disposed within a second resonator. An acoustic barrier between the first resonator and the second resonator may have a liquid resistance that is different from a liquid resistance that is provided between the first resonator and a back volume of the speaker module and/or between an external environment of the speaker. In one or more implementations, a third resonator may be provided, that is spatially separated from first and second nested and/or adjacent resonators.Type: ApplicationFiled: May 7, 2021Publication date: November 10, 2022Inventors: Oliver LEONHARDT, Anthony P. GRAZIAN, Claudio NOTARANGELO

Patent number: 11451902Abstract: Aspects of the subject technology relate to electronic devices having speakers with vented resonators. A vented resonator may have a resonator chamber and a channel that fluidly couples a front volume of the speaker with the resonator chamber. A vent such as a barometric vent may be disposed in a wall of the resonator chamber that separates the resonator chamber from the back volume of the speaker. The barometric vent may thus allow airflow from the front volume to the back volume via the resonator chamber, and prevent fluid flow from the front volume to the back volume via the resonator chamber.Type: GrantFiled: May 7, 2021Date of Patent: September 20, 2022Assignee: Apple Inc.Inventors: Oliver Leonhardt, Logan A. Rotolo, Claudio Notarangelo, Joshua Kim

Patent number: 10767927Abstract: This application relates to a portable electronic device including a processor and an operational component assembly, the operational component assembly including a frame. The frame carries a sensor that is coupled to the frame, where the sensor is capable of (i) receiving an environmental stimulus, and (ii) subsequently, generating an environmental parameter based on the environmental stimulus. The operational components further include a speaker that includes a magnetic driver that is capable of generating a magnetic field in response to receiving the instructions, and a diaphragm that is capable of actuating in response to the magnetic field being generated by the magnetic driver. An opening is disposed at an external surface of the frame such that when an amount of moisture is present within the volume, the magnetic driver receives the instructions from the processor to generate a magnetic field that actuates the diaphragm so as to expel the moisture.Type: GrantFiled: January 18, 2019Date of Patent: September 8, 2020Assignee: APPLE INC.Inventors: Brian A. Argyres, Matthew A. Donarski, Eric N. Nyland, Tyler B. Cater, Oliver Leonhardt

Patent number: 10728638Abstract: A transducer assembly including a transducer enclosure having an enclosure wall separating a surrounding ambient environment from an encased space, and a transducer module positioned within the encased space. The transducer module has a module wall that divides the encased space into an exterior chamber and an interior chamber and defines a fluid port between the exterior chamber and the interior chamber, the exterior chamber is between the module wall and the enclosure wall, the interior chamber is between the module wall and a sound radiating surface positioned within the transducer module, and the interior chamber is acoustically coupled to an acoustic port to the surrounding ambient environment. The enclosure wall is movable relative to the module wall and movement of the enclosure wall causes ejection of a fluid out of the interior chamber to the ambient environment.Type: GrantFiled: July 20, 2018Date of Patent: July 28, 2020Assignee: Apple Inc.Inventors: Oliver Leonhardt, Onur I. Ilkorur, Justin D. Crosby
