摘要： A system, method, and apparatus for separating speech signal from a noisy acoustic environment. The separation process may include directional filtering, blind source separation, and dual input spectral subtraction noise suppressor. The input channels may include two omnidirectional microphones whose output is processed using phase delay filtering to form speech and noise beamforms. Further, the beamforms may be frequency corrected. The omnidirectional microphones generate one channel that is substantially only noise, and another channel that is a combination of noise and speech. A blind source separation algorithm augments the directional separation through statistical techniques. The noise signal and speech signal are then used to set process characteristics at a dual input noise spectral subtraction suppressor (DINS) to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify speech signal.

摘要： A mobile station (100) that includes a processor (212) that selectively disables at least one station component to reduce electromagnetic noise generated by the station in the frequency range below 20 kHz when the mobile station is operated in the hearing aid compatible mode. The component can be, for example, a display (204), a light (206) or a wireless interface (208). The processor also can optimize characteristics of audio signals transmitted from the mobile station to the hearing aid for reproduction by the hearing aid. For instance, the processor can selectively adjust filter parameters (216) and/or a signal gain (218) applied to audio signals. A user interface (220) having a soft-key can be provided to cycle through various HAC options.

摘要： A display system includes a display and a control circuit operable with the display. The display is configured to provide visual output having a presentation orientation. When user input is received, the control circuit can alter the presentation orientation from an initial orientation in response to user input. When non-user events or device events are detected, the control circuit can revert the presentation orientation to the initial orientation in response to the non-user event or device event. Where the presentation orientation has a user input configuration associated therewith, the user input configuration can either be altered with the presentation orientation or retained in an initial disposition.

摘要： A wireless device (100) provides coordinated audio playback. The device (100) includes a network interface (112) that receives a signal from a sending or originating device (401) and sends a reply to the signal. A network delay value is then calculated based on the reply to the signal. The wireless device (100) then receives a location of the originating device (401) and at least a portion of an audio file. The wireless device (100) generates audio from the audio file, with the generation being coordinated with audio generation by the originating device (401) based upon the network delay value and the distance between the wireless device (100) and the originating device (401).

摘要： A speakerphone accessory (100) is provided for use with a portable telephone (102). The speakerphone accessory (100) has a high-level speaker assembly (222) that includes a transducer (500) coupled to first and second resonators (502, 504). The first and second resonators (502, 504) are designed so that the first resonator (502) is most efficient at a high frequency while the second resonator (504) has maximum response at a low frequency. The frequency ranges produced by the first and second resonators (502, 504) overlap to reproduce frequencies between the high and low frequencies. The high-level speaker assembly (222), therefore, provides an acoustic bandpass having improved response when compared to the response of the transducer (500) alone. In addition, the speakerphone accessory (100) has a housing (130) and porting structure which allows the accessory (100) and attached portable telephone (102) to be used in a variety of positions without obstructing sound generated by the high-level speaker assembly (222).

摘要： An ultrasonic communication system includes an omnidirectional ultrasonic transducer including a housing having a closed side and an open side defining an aperture in the housing. A diaphragm is mounted into the housing to form a sealed cavity between the diaphragm and the closed side of the housing. A second side of the diaphragm is free to transmit ultrasonic signals through the aperture. The diaphragm and aperture both have a largest dimension that is less than or equal to one-quarter wavelength of an ultrasonic signal to be transmitted by the transducer, such that the transducer behaves as a monopole and radiates substantially omnidirectionally.
