Abstract
An oscillation device and an electronic device are provided. The oscillation device is applied to the electronic device. The electronic device includes a fan. The oscillation device includes a detection module, an oscillation module, a variable capacitance module, and a control module. The control module is electrically coupled with the detection module, the variable capacitance module, and the oscillation module. The control module is configured to determine a capacitance adjustment parameter according to a preset correspondence, and a temperature of the electronic device and/or a rotational speed of the fan, where the preset correspondence includes a correspondence between capacitance adjustment parameters and temperatures of the electronic device and/or rotational speeds of the fan. The control module is configured to adjust a capacitance of the variable capacitance module according to the capacitance adjustment parameter.
