Publication number: 20170070839Abstract: A portable electronic device includes at least four speakers spaced apart from one another. An audio processor attenuates a high frequency portion of a left audio signal and a right audio signal to provide a processed left audio signal and a processed right audio signal. An audio router directs the left audio signal to only a first speaker, the right audio signal to only a second speaker, the processed left audio signal to a third speaker, and the processed right audio signal to a fourth speaker. The audio signals may be directed according to the orientation of the device. The cutoff frequency for attenuating the high frequency portion of the audio signals may be responsive to the orientation of the device. In other embodiments, the high frequency portion of the audio signals may be decorrelated to produce signals with high frequency portions for all speakers.Type: ApplicationFiled: September 2, 2016Publication date: March 9, 2017Inventors: Ryan J. Mihelich, Tomlinson Holman, Alexander P. Niemeyer, Timothy E. Sandrik

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

Publication number: 20160088379Abstract: An enclosure for an electronic device is enclosed. The enclosure includes rib structures configured to improve structural support to prevent damage and to dissipate vibration throughout the enclosure. The rib structure can receive a speaker module and a cap member. The rib structure and the speaker module can combine to form a three-dimensional volume allowing the speaker module in which the speaker module may project sound, thereby enhancing acoustic performance. Also, the cap member may be adhesively attached to the rib structure to provide additional structural support against vibration and abuse caused by load forces associated with a drop event.Type: ApplicationFiled: September 24, 2014Publication date: March 24, 2016Inventors: G. Kyle Lobisser, Jason S. Keats, Ryan J. Mihelich, Pablo Seoane Vieites, Kevin M. Kenney, John Raff, Erik A. Uttermann, Melody L. Kuna, Oliver C. Ross

Patent number: 8995673Abstract: An audio power management system manages operation of audio devices in an audio system. The audio power management system includes a parameter computer, a threshold comparator and a limiter. Audio signals generated with the audio system may be provided to the audio power management system. Based on a measured actual parameter of the audio signal, such as a real-time actual voltage and/or a real-time actual current, the parameter computer can derive estimated operational characteristics of audio devices, such as a loudspeaker included in the audio system. The threshold comparator may use the estimated operational characteristics to develop a threshold and manage operation of one of more devices in the audio system by monitoring the measured actual parameter, and selectively directing the limiter to adjust the audio signal, or another device in the audio system to protect or optimize performance.Type: GrantFiled: June 4, 2012Date of Patent: March 31, 2015Assignee: Harman International Industries, IncorporatedInventors: Ryan J. Mihelich, Jeffrey Tackett, Douglas K. Hogue

Patent number: 8675892Abstract: A spectral management system may be used in an audio system to receive and process audio signals having multiple distributed audio channels, such as a right, left, center, right side, left side, right rear and left rear channels. The spectral management system may separate and route a frequency range of audio content included in one or more of the distributed audio channels to other distributed audio channels. The separated and routed frequency range of audio content may be combined with audio content present on the other distributed audio channels to which the separated frequency range of audio content is routed. Separation, routing and combination may include bass audio content routing, mid-bass audio content routing, subwoofer audio content routing and treble audio content routing.Type: GrantFiled: April 30, 2010Date of Patent: March 18, 2014Assignee: Harman International Industries, IncorporatedInventors: Douglas K.

Patent number: 8559655Abstract: An automated audio tuning system may optimize an audio system for power efficiency when performing automated tuning of the audio system to optimize acoustic performance. The system may establish any number of different power efficiency weighting factors to provide a balance between acoustic performance and power efficiency during operation. The power efficiency weighting factors may range from representing optimizing power efficiency with constrained optimization of acoustic performance to optimized acoustic performance with minimized regard for power efficiency. For each of the efficiency weighting factors, the system may generate operational parameters, such as filter parameters, to achieve a target acoustic response while maintaining a determined level of power efficiency.Type: GrantFiled: May 18, 2010Date of Patent: October 15, 2013Assignee: Harman International Industries, IncorporatedInventors: Ryan J. Mihelich, Steven E. Hoshaw

Patent number: 8315421Abstract: A magnet structure for use with a loudspeaker has an interlocking mechanism. The magnet structure can include a magnet, a shell pot and at least one core cap. The shell pot can contain the magnet in its hollow interior. The magnet can be a single magnet or double magnets. The core cap has two surfaces. For a single magnet, one surface of the core cap faces the magnet. For double magnets, the core cap can be vertically disposed between the two magnets. The magnet, the core cap and the shell pot can interlock with one another such that a position of the magnet relative to the core cap and the shell pot can be rigidly preserved. The magnet can be configured to be, for example, overlapped, inserted, staked and/or engaged with at least one of the shell pot or the core cap.Type: GrantFiled: July 7, 2010Date of Patent: November 20, 2012Assignee: Harman International Industries, IncorporatedInventors: Ryan J.
