Abstract: This document describes systems and techniques for a non-contact vibration testing system for enhanced component placement. In one example a testing system includes a mounting device configured to receive an electronic device having a magnetic-field-sensitive component, the magnetic-field-sensitive component configured to vibrate in response to a variable-frequency magnetic field. A magnetic coil is configured to generate the variable frequency magnetic field in response to receiving an alternating electric current. The magnetic coil is disposed proximate to the mounting device to cause the variable-frequency magnetic field to propagate into a region of the mounting device in which the electronic device is configured to be received. The variable-frequency magnetic field configured to cause the magnetic-field-sensitive component to vibrate.

Abstract: The present document describes a low-emission cylindrical-winding battery design. The battery design is a rolled and stacked battery, with two or more winding rolls of cathode and anode layers separated by insulation layers, the winding rolls also being separated by a distance with the distance, in some embodiments, filled with a dielectric material. A first winding roll of first stacked anode and cathode layers and a second winding roll of second stacked anode and cathode layers are wound in a direction around a central axis of the battery. The first winding roll of first stacked anode and cathode layers follows a first stacking order with the anode and cathode layers alternating. The second winding roll of second stacked anode and cathode layers follows a second stacking order with the anode and cathode layers alternating opposite to the first stacking order. The alternating stacking orders cause the battery to produce a reduced H-field when compared with a battery having non-alternating stacking orders.

Abstract: Techniques and apparatuses are described for an earbud with low enoise. An electronic device includes: a flexible printed circuit (FPC) having first, second, and third regions, the FPC being shaped to form multiple layers including first, second, and third layers, the second region forming the second layer and being between the first layer formed by the first region and the third layer formed by the third region. The electronic device further includes a multi-layer board (MLB) in the first region. A battery connected to the FPC in the first region and disposed between the first and second regions. A speaker connected to the FPC in the second region and disposed between the second and third regions. Charger pins connected to the FPC in the third region. A microphone connected to the FPC in the third region. An infrared sensor connected to the FPC in the third region.
