  • SOUND PRESSURE LEVEL LIMITING
    Publication number: 20130259241
    Abstract: Limiting the sound pressure level presented to the listener's ears by one or more headphones, using processing capabilities of a personal media device. Headphones, coupled to audio signals from a personal media device, include a sensor to measure the sound pressure level presented to the listener's ears, and provide that measure to the personal media device. The personal media device, optionally aided by one or more analog circuits, adjusts the audio signal so that the sound pressure level is maintained within a recommended range.

  • Headphone response optimization
    Patent number: 9173045
    Abstract: Optimized sound waves presented to the listener by headphones, notwithstanding differences in ear geometry and headphone positioning. A test signal causes an acoustic sensor to receive sound waves actually formed in the listener's ear cavity. A response from the sensor is compared with an expected ear cavity transfer function, from which desired adjustments to the audio signal are determined. The audio signal might be received from an application program, calibrated by an interface software element, and adjusted thereby, before forwarding to the headphones. Calibration might be performed from when the headphones are positioned, or dynamically in response to changes in the transfer function.

  • EXTENSIBLE SMART HEADPHONE SYSTEM
    Publication number: 20130259255
    Abstract: A headphone system executing application programs on a media device to perform enhanced functions without burdening the headphones, including a headphone connector which receives signals from the media device, identifies command signals, and makes responses thereto. The system identifies the features of the headphones and what functions can be applied thereto, and performs those functions. The system includes one headphone cup for each ear, each including an embedded speaker and microphone. The microphones provide signals regarding sound present at the listener's ears, which are combined and input to the media device. The programs analyze signals from the microphones and apply signal processing techniques to outgoing signals.

  • VENTED ACOUSTIC ENCLOSURES AND RELATED SYSTEMS
    Publication number: 20170006373
    Abstract: An enclosure for a speaker transducer can have a front housing member and a rear housing member. Some enclosures position the speaker transducer between the front housing member and the rear housing member, and spaced apart from the rear housing member to define a rear chamber positioned between the speaker transducer and the rear housing member. The rear housing member can define a longitudinal axis. A first waveguide member and a second waveguide member can be longitudinally spaced apart from each other to define an acoustic waveguide therebetween oriented transversely relative to the longitudinal axis. A port can acoustically couple the acoustic waveguide with the rear chamber. A cross-sectional area of the waveguide can expand radially outward of the port. And, the acoustic waveguide can extend circumferentially around the longitudinal axis more than 90-degrees. Some embodiments include a speaker transducer and are suitable as a headphone.

  • Sound Producing System
    Publication number: 20100021000
    Abstract: A sound producing system includes an electro-acoustic transducer having an electromagnetic motor for moving a diaphragm of the transducer back and forth to create acoustic waves. The diaphragm has a surface that includes one or more of a surface of a dust cap of the diaphragm, a surface of a cone of the diaphragm, and a portion of a surface of a surround of the diaphragm. A solid gas impermeable cover faces the diaphragm surface and has a surface which faces the diaphragm surface. At least a portion of the cover surface has a contour which is substantially the same as a contour of the diaphragm surface. The system includes an asymmetric exit for the acoustic waves to leave a volume defined between the diaphragm surface and the cover surface.
