The current detection circuit includes a current detection module and an analog-to-digital converter. The current detection module samples a current flowing through the speaker based on current mirror technology, and converts the current into a voltage to output a first voltage signal and a second voltage signal. The analog-to-digital converter converts the first voltage signal and the second voltage signal into a PDM code, to calculate a current parameter of the speaker."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current detection circuit, chip, and current detection method used for speaker protection","description":"A current detection circuit and method for protecting a speaker, and a chip are provided.
