Publication number: 20170223462Abstract: An electronic device whose enclosure or housing panel is used as part of an acoustic system is described. The panel is divided into several sub-panels. For each sub-panel, the device includes one or more actuators attached to vibrate the sub-panel. The actuator and its attached sub-panel convert an audio signal to acoustic output. Each actuator and sub-panel combination may receive a separate audio signal. The device includes a digital signal processor for controlling each of the sub-panel driving audio signals. The device may further include one or more backing frames that are attached to the panel to provide boundary conditions to the sub-panels. The boundary conditions define a resonance frequency for each sub-panel.Type: ApplicationFiled: October 29, 2015Publication date: August 3, 2017Inventors: Matthew A. Donarski, Daniel K. Boothe, Justin D. Crosby, Mitchell R. Lerner

Patent number: 9654863Abstract: A computer system having a loudspeaker mounted on a main logic board by a hermetic seal, is disclosed. More particularly, embodiments of the computer system include an acoustic cavity defined between the loudspeaker, the main logic board, and the hermetic seal. Embodiments of the computer system may include a compressible seal separated from the hermetic seal by the loudspeaker and/or the main logic board. The compressible seal may define an acoustic channel and the loudspeaker may emit sound in a high frequency range through the acoustic channel toward a system exit. Other embodiments are also described and claimed.Type: GrantFiled: December 8, 2014Date of Patent: May 16, 2017Assignee: Apple Inc.Inventors: Justin D Crosby, Matthew A Donarski, Andrew P Bright, Joss N Giddings, Ron A Hopkinson, Nathan A Johanningsmeier, William F Leggett, Mikael M Silvanto

Publication number: 20160277819Abstract: An electronic device including a frame member suitable for use with an audio driver is disclosed. The frame member may include a recessed region that receives the audio driver. The frame member may further include a flange member surrounding the recessed region. The frame member may be formed from a material having a relatively high coefficient of thermal conductivity. Accordingly, the frame member can dissipate thermal energy (heat) generated from the audio driver. In addition, the frame member may be seated in an enclosure of an electronic device in a manner that allows the frame member to pass the thermal energy to the enclosure. Also, the frame member may include a ferromagnetic material, which may cause the frame member to direct magnetic flux from a magnet of the audio driver in a desired manner.Type: ApplicationFiled: March 16, 2016Publication date: September 22, 2016Inventors: Michael D. McBROOM, Bartley K. ANDRE, Mikael M. SILVANTO, Matthew A. DONARSKI, Alexander V. SALVATTI, Daniel K. BOOTHE, Ryan J. MIHELICH, Sabrina K. PASEMAN

Patent number: 9264789Abstract: An acoustic transformer includes at least one outer boundary wall. A plurality of inner walls are disposed within the outer boundary wall. The outer boundary wall and the inner walls define a substantially annular input opening divided by at least some of the inner walls into a plurality of circumferentially-spaced input sections. Each of the input sections has an inner circumferential side and an outer circumferential side. A substantially rectangular output opening is divided by at least some of the inner walls into a plurality of output sections. Each of a plurality of acoustic paths interconnects a respective one of the input sections with a respective one of the output sections. The acoustic paths maybe identical or individually unique in order to change the both the shape of the acoustic wavefront at the output and the energy distribution.Type: GrantFiled: May 30, 2014Date of Patent: February 16, 2016Assignee: Robert Bosch GmbHInventor: Matthew A. Donarski
