Patent number: 11950036Abstract: An electronic device can include a housing defining an aperture and a display positioned in the aperture. The display and the housing can define an internal volume in which a speaker assembly is positioned. The speaker assembly can include a speaker module and a speaker enclosure in fluid communication, with the speaker enclosure at least partially defining a speaker volume.Type: GrantFiled: February 7, 2023Date of Patent: April 2, 2024Assignee: APPLE INC.Inventors: Paul X. Wang, Chanjuan Feng, Christopher Wilk, Dinesh C. Mathew, Keith J. Hendren, Stuart M. Nevill, Daniel K. Boothe, Nicholas A Rundle, Simon S. Lee, Xiang Zhang, Thomas H. Tsang, Rebecca J. Mikolajczyk

Publication number: 20240007782Abstract: Improved acoustic devices include water-resistant venting across various surfaces inside acoustic devices such as speakers and microphones. Surfaces such as an acoustic diaphragm, a cover for a resonant chamber, and a cover for an external port of an acoustic transducer may include design features that create or enhance gas-permeable and water impermeable attributes. Such design features include, for example, a series of apertures in the vented surface.Type: ApplicationFiled: May 2, 2023Publication date: January 4, 2024Inventors: Marco BARATELLI, Justin D. CROSBY, Thomas H. TSANG

Patent number: 10433048Abstract: A micro speaker assembly including a speaker enclosure having an enclosure wall separating a surrounding environment from an encased space, wherein the enclosure wall defines, in part, an acoustic channel that acoustically couples the encased space to the surrounding environment, and the enclosure wall comprises a chemically etched insert molded metal portion that is mechanically interlocked and hermetically sealed to a plastic portion. The micro speaker further including a speaker assembly positioned within the encased space, the speaker assembly having a sound radiating surface facing the metal portion of the enclosure wall, a voice coil extending from the sound radiating surface, a magnet assembly having a magnetic gap aligned with the voice coil, and an acoustic chamber formed, in part, by the metal portion of the enclosure wall and the sound radiating surface.Type: GrantFiled: August 31, 2017Date of Patent: October 1, 2019Assignee: Apple Inc.Inventors: Thomas H. Tsang, Onur I. Ilkorur, Derek C. Krass, Logan A. Rotolo, Christopher Wilk

Patent number: 10299032Abstract: A micro-speaker assembly including an enclosure having an enclosure wall separating a surrounding environment from an encased space, wherein the enclosure wall defines an acoustic port from the encased space to the surrounding environment; a sound radiating surface positioned within the encased space and dividing the encased space into a front volume chamber and a back volume chamber, wherein the front volume chamber is acoustically coupled to a first surface of the sound radiating surface and the acoustic port, and the back volume chamber acoustically coupled to a second surface of the sound radiating surface; and a resonator acoustically coupled to the front volume chamber, wherein the resonator comprises a neck acoustically coupled to an acoustic cavity, and an opening to the neck is positioned at a distance from the acoustic port that corresponds to a quarter wavelength resonance of the front volume chamber.Type: GrantFiled: September 11, 2017Date of Patent: May 21, 2019Assignee: Apple Inc.Inventors: Anthony P. Grazian, Christopher Wilk, Claudio Notarangelo, Hongdan Tao, Michael J. Newman, Onur I. Ilkorur, Thomas H. Tsang

Patent number: 10015574Abstract: A portable electronic device is described and includes a device housing, an acoustic housing disposed within the device housing and defining an interior volume, a speaker diaphragm assembly disposed within the interior volume and in fluid communication with a first opening leading out of the housing, and a microphone disposed within the interior volume and in fluid communication with a second opening leading out of the acoustic housing. Placing both the speaker diaphragm assembly and microphone within the same acoustic housing allows both components to share common power and data transfer circuitry. Furthermore, the additional volume of the acoustic housing used to accommodate the microphone can improve the acoustic performance of the speaker diaphragm assembly by increasing the back volume associated with the speaker diaphragm assembly.Type: GrantFiled: September 1, 2017Date of Patent: July 3, 2018Assignee: Apple Inc.Inventors: Thomas R. Luce, Robert I. Luan, Thomas H. Tsang
