Adaptive resonance-controlled audio systems and methods

An electronic device, comprising:

• a speaker having a resonant frequency that changes over time during operation of the speaker while the speaker is un-occluded;
• an electronic component;
• and
• one or more processors configured to:
• obtain an electrical characteristic of the electronic component during operation of the speaker while the speaker is un-occluded;
• determine, based on the electrical characteristic, a resonant frequency of the speaker;
• and
• generate an audio output with the speaker at an output frequency that is different from the resonant frequency by an amount that is based on a frequency of a prior output tone from the speaker.

An electronic device, comprising:

• a speaker;
• an electronic component;
• and
• one or more processors configured to:
• receive an emergency alert trigger;
• determine, responsive to the emergency alert trigger, a resonant frequency of the speaker based on an electrical characteristic of a component of the speaker;
• and
• generate, with the speaker, an emergency alert including audio content at a frequency corresponding to a semitone bin corresponding to the resonant frequency.
