Patent number: 12317028Abstract: A multimedia device having a housing that includes a display screen, two tweeters, two mid-range drivers, and two woofers, which are integrated into the housing. Both woofers are disposed at a first distance from a center vertical axis of the housing in opposite horizontal directions, both tweeters are disposed at a second distance from the center vertical axis in the opposite horizontal directions, and both mid-range drivers are disposed at a third distance from the center vertical axis in opposite horizontal directions. In addition, both the first and second distances are greater than the third distance.Type: GrantFiled: August 15, 2022Date of Patent: May 27, 2025Assignee: Apple Inc.Inventors: Daniel K. Boothe, Martin E. Johnson, Ismael H. Nawfal, Timothy J. Valentine, Stuart M. Nevill, Chanjuan Feng

Publication number: 20250106562Abstract: Aspects of the subject technology relate to stiffness reduction for audio transducers, such as speakers. Stiffness reduction can be provided using one or more magnetic structures configured to move with a voice coil and/or a diaphragm of the speaker, and assist in the motion of the voice coil and/or diaphragm via magnetic interaction with one or more magnets of the speaker. In one or more implementations, the one or more magnetic structures may form a tri-stable system with the one or more magnets.Type: ApplicationFiled: September 27, 2023Publication date: March 27, 2025Inventors: Stuart M. NEVILL, Andrew M. HULVA, Chanjuan FENG, Martial A. ROUSSEAU, Scott P. PORTER

Publication number: 20240414462Abstract: A speaker includes a flexible layer, a sensor configured to detect a curvature of the flexible layer, and a transducer configured to vibrate the flexible layer. The vibrations of the flexible layer generate sound waves and output generated by the transducer is based on a curvature of the flexible layer.Type: ApplicationFiled: August 23, 2024Publication date: December 12, 2024Inventors: Paul X. Wang, Chanjuan Feng

Patent number: 12108200Abstract: A speaker includes a housing having walls that define a cavity and a diaphragm covering the cavity and configured to vibrate under application of a magnetic field. The vibration produces sound waves. The walls are configured to deform under bending stress. The speaker is configured produce the sound waves both in an undeformed state and in a deformed state. Another speaker includes a flexible layer, a sensor configured to detect a curvature of the flexible layer, and a transducer disposed on and configured to vibrate the flexible layer. The vibrations of the flexible layer generate sound waves and output generated by the transducer is based on the curvature of the flexible layer.Type: GrantFiled: August 4, 2022Date of Patent: October 1, 2024Assignee: APPLE INC.Inventors: Paul X. Wang, Chanjuan Feng

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
