Abstract: The speaker coil in a dynamic speaker in a mobile computing device can be used to generate radio frequency (RF) signals having a frequency of about 100 kHz or greater. A speaker amplifier drives the dynamic speaker to produce sound and RF circuitry drives the speaker amplifier to generate the RF signals having a frequency of about 100 kHz or greater. The speaker coil can comprise a tap at an appropriate point between the ends of the coil to cause the coil to operate at resonance over a desired RF frequency band. A low-pass filter can be positioned at the speaker amplifier output to protect the speaker amplifier from RF energy generated by the RF circuitry and a high-pass filter can be positioned at the output of the RF circuitry to protect the RF circuitry from audio energy generated by the speaker amplifier.

Abstract: Adaptive filtering is described for use with amplifiers for any wired speaker. In one example, an apparatus includes an audio cable to provide an analog audio signal to an audio transducer, such as a speaker, the audio cable also receiving a modulated noise current, an output amplifier to receive an audio input, to generate an audio output by amplifying the audio input, and to provide the audio input to the audio cable, and a feedback system to receive the audio output and to receive a reference signal and to generate a noise cancellation signal to the output amplifier, the noise cancellation signal to cancel the modulated noise current.

Abstract: Technologies for reducing the impact of inductors on electrical traces are disclosed. In an illustrative embodiment, conductive ink is applied in a silk screen layer on top of a solder mask of a circuit board. The conductive ink forms shield regions under and near where inductors are placed and/or where a power plane is routed. The conductive shield regions may be coupled to a ground plane in the circuit board. The conductive shield regions can partially shield traces under and near the inductor, reducing the noise induced on nearby traces. The conductive shield regions can allow traces for high-speed input/output signals to be routed closer to the inductor, reducing the size, number of layers, and/or cost of the circuit board. In some embodiments, the conductive shield regions can shield emissions from the power plane, reducing interference on antennas of a device.

Abstract: Wire coils are distributed over the bottom surface of an inner chamber of a vapor chamber. The working fluid of the vapor chamber comprises ferromagnetic particles that are attracted to a wire coil as current passes through the wire coil. The resulting increase in the volumetric concentration of ferromagnetic particles in the vicinity of the activated wire coil increases the capacity of the working fluid to remove heat from an integrated circuit component attached to the vapor chamber in the region of the activated wire coil. The vapor chamber wire coils can be activated based on performance metrics associated with the processor units of an integrated circuit component, thereby allowing for the thermal resistance of the working fluid to be dynamically adjusted based on the workload executing on the integrated circuit component and power consumption transients.
