Abstract: The subject matter described herein provides systems and techniques for controlling the production of eNoise in an audio playback system. The eNoise may be an audible noise produced when a current, such as a noise/ripple current, flows through a battery of the audio playback system. Such eNoise may be reduced by limiting the current, such as noise/ripple current, flowing through the battery. In some examples, the noise/ripple current may be diverted to the main board of the audio playback system by adding a source of current. A circuit to produce such a current may include transistor(s), capacitor(s), and/or resistor(s). Using the current source and/or such a circuit may also divert the noise/ripple current away from the battery, thereby reducing the eNoise produced.

Abstract: The present disclosure describes a system and method for protecting an electronic device from high voltages that may exceed tolerance limits for circuitry within the electronic device. A protection circuit blocks high voltages from the device components through gating techniques. Such gating techniques may similarly be used to control whether power is received by the electronic components when an error condition is detected by a control unit.
