摘要： A wearable audio device sized to fit within an ear of an user comprises an outer housing; a circuit board positioned within the outer housing; a battery having an anode and a cathode, the battery being connected to the circuit board; a speaker adjacent the battery; and an electromagnetic interference (“EMI”) shield tab coupled to the anode. The EMI shield tab may be configured to shield the speaker from EMI generated by the circuit board and to provide an electrical interconnection to the anode. The EMI shield tab may be comprised of a high magnetic flux permeable metal material

摘要： An antenna is provided for a wearable personal computing device, such as an earbud. The antenna integrates with other components of the wearable device, such as an input control. For example, the antenna may at least partially surround a portion of a touchpad input at a surface of the device that is exposed when the device is worn. In one example, the antenna shares a ground plane with the touchpad. In another example, the antenna includes two nested traces, wherein a first trace is connected to ground and a second trace is connected to an antenna feed.

摘要： This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.

摘要： A first device provides both power and data to a second device over a power line connection between the two devices. The first device includes a power line extending from a power supply, a ground line extending from a ground, a first impedance in the power line, and a second impedance in the ground line. A modulator comprised of a transistor and modulator impedance is between the first impedance and the second impedance, and a tank capacitor is between the power line and the ground line, outside the first impedance and second impedance. A comparator is coupled between the first and second impedance. A switch may be included to short out the first and second impedance, thereby enabling transmission of only power for period of time, and return to a mode of transmitting both data and power. The first device may also receive data from the second device over the power line connection.

摘要： The technology provides for a magnetic sensing device. The device includes a magnetic sensor configured to generate a first output triggered by a first polarity and a second output triggered by a second polarity. The device includes a first magnet, a second magnet, and a third magnet. The device may be configured such that, when the second magnet is not within a predetermined distance from the first magnet, a magnetic field from the first magnet having the first polarity causes the first output and the second output to have a first set of values. The device may be configured such that, when the second magnet is within the predetermined distance from the first magnet, a magnetic field from the third magnet having the second polarity causes the first output and the second output to have a second set of values.

摘要： A wireless accessory has one or more sensors positioned at an outer periphery of its housing, thereby forming a knob-like input. The sensors may be configured to detect a change in contact force or contact location of first and second fingertips at respective first and second opposite sides of the periphery. An input gesture is determined based on the detected change, and a command corresponding to the gesture may be executed.

摘要： The present disclosure provides a magnetic system within a case for an electronic accessory. The case may include a housing portion and a lid coupled to the housing portion. Within the housing portion may be a housing magnet. The housing magnet may be oriented such that the magnetic field of the housing magnet is oriented transverse to a longitudinal axis of the case. The housing magnet may have a size and strength to magnetically couple the electronic accessory within a cavity of the housing. A hinge magnet may be located along an axis of rotation of the lid with respect to the housing. The hinge magnet and housing magnet may magnetically interact to form a bistable magnetic hinge. Thus, the one housing magnet may be large enough and have a strong enough magnetic field to perform various functions.

摘要： A first electronic device, electronically coupled to a second device for supplying a charge to the second electronic device, tracks the voltage requirements of the second device and dynamically adjusts its output voltage upwards or downwards to match such requirements. The second electronic device may provide feedback to the first electronic device through a feedback loop. The feedback may include an indication of the voltage requirements and/or instructions for adjusting the voltage output of the first electronic device. The second device may be, for example, a wearable audio device, while the first device is a case for the wearable audio device.
