    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 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 portable electronic device that provides compact configurations for audio elements are disclosed. The audio elements can be drivers (e.g., speakers) or receivers (e.g., microphones). In one embodiment, an audio element can be mounted on or coupled to an intermediate structure (e.g., a flexible electrical substrate) having an opening therein to allow audio sound to pass there through. In another embodiment, an audio chamber can be formed to assist in directing audio sound between an opening an outer housing and a flexible electronic substrate to which the audio element is mounted or coupled thereto. In still another embodiment, a barrier, such as a mesh barrier, can be provided in an opening of an outer housing so that undesired foreign substances can be blocked from further entry into the opening in the outer housing.

    Abstract: A portable audio device, which includes active noise cancellation circuitry, a hearing aid compliant magnetic radiator, and a speaker/earpiece, is surrounded by ambient acoustic noise. The active noise cancellation circuitry provides an anti-noise signal at an input of the speaker to control/reduce the ambient acoustic noise outside of the device. In addition, the active noise cancellation circuitry provides an inverse anti-noise signal to an input of the magnetic radiator. The magnetic fields produced by the speaker driven by the anti-noise signal and the magnetic radiator driven by the inverse anti-noise signal cancel each other out through phase cancellation such that a hearing aid using a telecoil coupled to the audio device does not produce significant audio waves based on either of these signals. Other embodiments are also described.

    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.
