The method also includes converting the first load current to a digital value using a second load current through a second resistor as a reference input. The second resistor is part of a circuit that reduces an effect of a temperature coefficient of resistance of the first resistor. The method also includes comparing the digital value of the first load current to a threshold value. The method further includes, responsive to the first load current being larger than the threshold value, generating an instruction to take an action to protect the speaker."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection of a speaker from thermal damage","description":"A method of protecting a speaker from thermal damage includes determining a first load current through a first resistor that is coupled to the speaker.
