The control circuit is configured to drive the speaker at a predetermined frequency that may correspond to a resonance frequency. The control circuit comprises a speaker driver in communication with a controller. The controller is operable to control a drive frequency of the speaker by monitoring at least a sample of each of a plurality of wavelengths of a current draw of the speaker in the form of a voltage signal. Based on the voltage signal, the controller is operable to identify a voltage differential and adjust the drive frequency of the speaker in response to the voltage differential to maintain the predetermined frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for driving a low frequency speaker","description":"A control circuit configured to control a speaker is disclosed.
