Abstract: A portable audio device has a voice coil audio signal processor in which a desired audio content signal is combined with an anti-noise signal produced by an active noise cancellation block. A voice coil amplifier receives a volume setting and is coupled to an output of the voice coil audio signal processor. A speaker is coupled to an output of the voice coil amplifier. In addition, a telecoil audio signal processor also receives the desired audio content, and feeds a telecoil amplifier that receives a telecoil coupling strength setting, followed by a telecoil. Other embodiments are also described and claimed.

Abstract: A mobile communications device contains at least two microphones. One microphone is located away from the handset receiver and serves to pick up voice of a near end user of the device for transmission to the other party during a call. Another microphone is located near the handset receiver and serves to pick up acoustic output of the handset receiver (a far end signal). A signal processor measures the frequency response of the receiver. The signal processor performs spectral analysis of the receiver frequency response to determine whether or not the device is being held at the ear of the user. On that basis, the device automatically changes its operating mode, e.g., turns on or off a touch sensitive display screen during the call. Other embodiments are also described.

Abstract: A hearing aid compatible portable electronic audio device is configured to automatically determine whether or not the device is being used by a hearing impaired user who is wearing a hearing aid, and select a mode of operation based on this determination. The device includes a proximity sensor and a magnetic field sensor. The proximity sensor is used to detect a change in distance of the device to the user's ear. The magnetic field sensor is used to detect a change in magnetic field caused by the device moving relative to the hearing aid. The device selects between a normal audio mode of operation and a hearing aid compatible mode of operation based on both the change in detected distance and the change in detected magnetic field. Other embodiments are also described and claimed.

Abstract: A wireless electronic device may be provided with components such as electrical and structural components. During transmission of radio-frequency signals, antennas and wireless communications circuitry of the wireless electronic device may produce associated time-varying magnetic fields. One or more components may be covered with magnetic-resistant shield structures that protect the components from the time-varying magnetic fields by preventing magnetic-induced vibrations. The magnetic-resistant shield structures may include a conductive base layer such a layer of brass. A magnetic-resistant layer may be plated onto the conductive base layer. The magnetic-resistant layer may be formed from an amorphous nickel-phosphorous alloy. The amorphous nickel-phosphorous alloy may be produced by controlling the manufacturing temperature and proportion of phosphorous in the alloy while performing the plating operations within a length of time that ensures non-equilibrium conditions during the plating operations.

Abstract: A mobile communications device contains at least two microphones. One microphone is designated by a selector to provide a voice dominant signal and another microphone is designated to provide a noise or echo dominant signal, for a call or a recording. The selector communicates the designations to a switch that routes the selected microphone signals to the inputs of a processor for voice signal enhancement. The selected voice dominant signal is then enhanced by suppressing ambient noise or canceling echo therein, based on the selected noise or echo dominant signal. The designation of microphones may change at any instant during the call or recording depending on various factors, e.g. based on the quality of the microphone signals. Other embodiments are also described.

Abstract: A connector for receiving a cylindrical plug includes a body defining a plug aperture and a cavity for receiving the cylindrical plug. A plurality of electrical contacts in communication with the cavity make electrical connections with the cylindrical plug and retain the cylindrical plug. A microphone is coupled to the body such that the plug aperture and the cavity provide an acoustic path to the microphone. The microphone may be at an end of the connector opposite the plug aperture or on a side of the connector adjacent the plug aperture. The connector allows a microphone to be added to a device, such as a mobile telephone, without the need for an additional external aperture. The microphone in the connector may operate with a second microphone and processing electronics in the device to provide audio processing functions such as noise cancellation or audio beamforming.
