Abstract: Disclosed are passive acoustic structures, portable audio devices configured for use with the passive acoustic structures and methods for enhancing the frequency output of a speaker of a portable device configured for use with a disclosed passive acoustic structure. The disclosed portable audio device may include an opening proximal a speaker cavity of the device, a shutter or door to open and close the opening so that the device interoperates with a docking station of a passive acoustic structure including a labyrinth or a transmission line system that may increase the frequency range of the system. For an end user to experience the music and multimedia features of a portable audio device, and in particular a mobile communication device, the above-described passive acoustic structure may provide a bass enhancement for the typically small loudspeaker of a portable audio device with no additional loudspeaker and therefore no additional circuitry.

Abstract: An intelligent noise reduction system (100) is provided. The system can include a gradient microphone (110) to produce a gradient speech signal, a correction unit (116) to de-emphasize a high frequency gain imparted by the gradient microphone, a Voice Activity Detector 120 (VAD) to determine portions of speech activity (701) and portions of noise activity (702) in the gradient speech signal, an Automatic Gain Control 130 (AGC) unit to adapt a speech gain (740) of the gradient speech signal to minimize variations in speech signal levels, and a controller (140) to control the speech gain applied by the AGC to the portions of noise activity to preserve a speech to noise level ratio between speech activity and noise activity in the gradient speech signal.

Abstract: Un sistema, método, y aparato para separar la señal de voz de un ambiente acústico ruidoso. El proceso de separación puede incluir filtración bidireccional, separación de fuente ciega, y supresor de ruido de sustracción espectral de entrada doble. Los canales de entrada pueden incluir dos micrófonos omnidireccionales cuya salida se procesa utilizando filtración de retraso de fase para formar formas de haz de voz y ruido. Además, las formas de haz pueden ser de frecuencia corregida. Los micrófonos omnidireccionales generan un canal que substancialmente es únicamente ruido, y otro canal que es una combinación de ruido y voz. Un algoritmo de separación de fuente ciega aumenta la separación direccional mediante técnicas estadísticas. La señal de ruido y la señal de voz se utilizan después para ajustar las características del proceso en un supresor de sustracción espectral de ruido de entrada doble (DINS - dual input noise spectral) para reducir sustancialmente o eliminar el componente de ruido. De esta manera, el ruido se elimina eficazmente de la señal de combinación para generar una señal de voz de buena calidad.

Abstract: A speaker (302) is arranged in an enclosure formed by a front housing portion (200) and a rear housing portion (202), so that an air-gap is between a diaphragm (314) of the speaker and ports (114) formed in the front housing that face the diaphragm. The air-gap provides an acoustic leak into the enclosure, which makes the frequency response of the speaker relatively independent of the seal formed by a human ear and the front housing portion. Sound-absorbing material (304,300) disposed on either side of the speaker, ports that extend beyond the circumference of the speaker, and a filter (600) can be added to further enhance the audio quality of the speaker.

Abstract: Disclosed is a portable audio device and a quick-disconnect passive acoustic cover. The portable audio device includes a housing and a speaker supported by the housing that have a first system frequency response. The speaker of the portable audio device has a first side and a second side associated with a first audio port and a second audio port, associated with a first acoustic load and a second acoustic load respectively. The housing is configured to removably receive the cover which is configured to redefine at least one of the first acoustic load and the second acoustic load to replace the first system frequency response with a second system frequency response. The cover provides one or more additional surrounding structures, which replace the inherent frequency response with an improved frequency response. Different embodiments of the disclosed cover provide a plurality of sound quality enhancement options to a user.

Abstract: A noise suppression circuit for use in an audio signal processing circuit is provided. The noise suppression circuit includes a plurality of different types of noise activity detectors, which are each adapted for detecting the presence of a different type of noise in a received signal. The noise suppression circuit further includes a 10 plurality of different types of noise reduction circuits, which are each adapted for removing a different type of detected noise, where each noise reduction circuit respectively corresponds to one of the plurality of noise activity detectors. The respective noise reduction circuit is then selectively activated to condition the received signal to reduce the amount of the detected types of noise, when each one of 15 the plurality of noise activity detectors detects the presence of a corresponding type of noise in the received signal.

Abstract: A method and apparatus for modular authentication of a wireless communication device (120) including a portable communication device (210) and a wireless communication module (220) coupleable thereto is disclosed. When the wireless communication module (220) receives information (706) from the portable communication device (210), it determines whether the information received is authentic information (710) and operates together with the portable communication device (210) as a wireless communication device (120) in a communication system (100) in response to the information received being authentic information (720). In addition, a method and apparatus is disclosed for checking subsidy lock in a wireless communication device (120) capable of operating in a communication system (100), the wireless communication device comprising a first module (210), a second module (220) and a subscriber identity module (230) coupled to the first and second modules (210, 220). The first and second modules (210, 220) independently determine whether subsidy lock information stored in the subscriber identity module (230) corresponds to correct subsidy lock information (614, 618), and set a state of the wireless communication device (120) as operable in the communication system (100) in response to determining that the subsidy lock information stored in the subscriber identity module (230) corresponds to the correct subsidy lock information (614, 618).
