Patent number: 11917350Abstract: A loudspeaker having a compressible lead wire is described. The lead wire carries an electrical audio input signal to a voice coil. The electrical audio input signal drives the voice coil to oscillate in an axial direction. The compressible lead wire includes an elastic portion that stretches and compresses in the axial direction to allow the voice coil to oscillate freely. The elastic portion includes several compressible elements that are located within a cavity of the loudspeaker. The compressible elements extend through the cavity in the axial direction. Other aspects are also described and claimed.Type: GrantFiled: August 23, 2021Date of Patent: February 27, 2024Assignee: Apple Inc.Inventors: Christopher Wilk, Logan A. Rotolo, Anthony P. Grazian, Onur I. Ilkorur

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.

Publication number: 20190281381Abstract: An acoustic enclosure has a housing at least partially defining an acoustic chamber for an acoustic radiator. The housing defines an acoustic port from the acoustic chamber to a surrounding environment. An acoustic resonator has a first resonant chamber and a second resonant chamber. The acoustic resonator also has a first duct to acoustically couple the first resonant chamber with the acoustic chamber and a second duct to acoustically couple the second resonant chamber with the first resonant chamber. An electronic device can have an electro-acoustic transducer. Circuitry in the electronic device can drive the electro-acoustic transducer to emit sound over a selected frequency bandwidth. Damping provided by the first and the second resonant chambers can de-emphasize one or more frequencies and/or extend a frequency response of the acoustic enclosure to improve perceived sound quality emitted by the electronic device.Type: ApplicationFiled: March 9, 2018Publication date: September 12, 2019Inventors: Hongdan Tao, Anthony P.

Patent number: 10271127Abstract: This disclosure describes a speaker assembly suitable for use in a portable electronic device utilizing water resistant ports. The speaker assembly can have an open back that subjects a back volume of the speaker to pressure differentials within a device housing of the portable electronic device. The speaker assembly can utilize a speaker surround having a varying thickness.
