Patent number: 10109292Abstract: An audio system includes an external microphone to receive a near-end audio content and a loudspeaker transducer and a corresponding enclosure defining an acoustic chamber. An internal pressure-gradient microphone is positioned in the acoustic chamber to detect a radiated output from the loudspeaker transducer. The audio system also includes a processor and a memory having instructions that, when executed by the processor, cause the audio system to receive a near-end signal from the external microphone and a reference signal from the internal microphone. The instructions, when executed, further cause the processor to cause the audio system to filter the reference signal from the near-end signal to define a clean near-end signal, and to emit the clean near-end signal. Related principles are described by way of reference to method and apparatus examples.Type: GrantFiled: June 3, 2017Date of Patent: October 23, 2018Assignee: Apple Inc.Inventors: Sylvain J.

Patent number: 10110995Abstract: An arrangement and method for converting an input signal into a mechanical or acoustical output signal by using a transducer and additional means for generating a desired transfer behavior and for protecting said transducer against overload. Transducers of this kind are for example loudspeaker, headphones and other mechanical or acoustical actuators. The additional means comprise a controller, a power amplifier and a detector. The detector identifies parameters of the transducer model if the stimulus provides sufficient excitation of the transducer. The detector permanently identifies time variant properties of the transducer for any stimulus supplied to the transducer. The controller provided with this information generates a desired linear or nonlinear transfer behavior; in particular electric control linearizes, stabilizes and protects the transducer against electric, thermal and mechanical overload at high amplitudes of the input signal.Type: GrantFiled: October 17, 2013Date of Patent: October 23, 2018Inventor: Wolfgang Klippel

Patent number: 10091584Abstract: In some embodiments, portable speakers can be small and lightweight and can communicate with one or more audio device over wired or wireless connections. In some embodiments, portable speakers achieve reduced complexity as compared to typical high fidelity systems (e.g., by including a reduced number of speaker drivers and amplifiers), while still maintaining high fidelity stereo audio playback, thereby achieving both portability and high quality audio capability. For instance, certain implementations of the speaker include two primary speakers disposed on opposing faces of the speaker enclosure (e.g., full or mid-range drivers) and two tweeters, also disposed on opposing faces. Primary speakers can be disposed on respective ends of the housing and each can output a different stereo channel. Each tweeter can be positioned on different face of the housing. The speaker system according to some embodiments generates a mono high frequency signal to drive the tweeters.Type: GrantFiled: April 26, 2017Date of Patent: October 2, 2018Assignee: Fugoo CorporationInventors: Frank Barone, Dennis Stone

Patent number: 10079028Abstract: Embodiments of the present invention relate to enhancing sound through reverberation matching. In sonic implementations, a first sound recording recorded in a first environment is received. The first sound recording is decomposed to a first clean signal and a first reverb kernel. A second reverb kernel corresponding with a second sound recording recorded in a second environment is accessed, for example, based on a user indication to enhance the first sound recording to sound as though recorded in the second environment. An enhanced sound recording is generated based on the first clean signal and the second reverb kernel. The enhanced sound recording is a modification of the first sound recording to sound as though recorded in the second environment.Type: GrantFiled: December 8, 2015Date of Patent: September 18, 2018Assignee: Adobe Systems IncorporatedInventors: Ramin Anushiravani, Paris Smaragdis, Gautham Mysore
