Abstract: Aspects of the subject technology relate to providing audio alerts with electronic devices. An audio alert may be provided, in part, using power management operations that manage one or more both of the instantaneous power usage for providing the audio alert, and the long-term power usage for providing the audio alert.

Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may operate the speaker to generate audio output at one or more resonance frequencies of the speaker and/or the electronic device. This can allow the electronic device to generate particularly loud audio outputs while reducing the power consumption used to generate those audio outputs. In order, for example, to help ensure that the audio output is generated at the resonance frequencies, the electronic device can determine the resonance frequencies prior to generating the audio outputs. For example, the electronic device may determine resonance frequencies by obtaining one or more electrical characteristics of an electronic component while operating the speaker, and determine the resonance frequencies based on the obtained electrical characteristics.
