Oscillation device and electronic device

An oscillation device, applied to an electronic device comprising a fan, the oscillation device comprising a detection module, an oscillation module, a variable capacitance module, and a control module, wherein:

• the detection module is configured to detect a temperature of the electronic device and/or a rotational speed of the fan;
• the oscillation module is configured to oscillate to output a clock signal, a frequency of the clock signal varies with a capacitance of the variable capacitance module;
• the variable capacitance module is electrically coupled with the oscillation module;
• and
• the control module is electrically coupled with the detection module, the variable capacitance module, and the oscillation module, and is configured to:
• determine a capacitance adjustment parameter according to a preset correspondence, and the temperature of the electronic device and/or the rotational speed of the fan, wherein the preset correspondence comprises a correspondence between the capacitance adjustment parameter and the temperature of the electronic device and/or the rotational speed of the fan, and the capacitance adjustment parameter is configured to change the capacitance of the variable capacitance module;
• and
• adjust the capacitance of the variable capacitance module according to the capacitance adjustment parameter.
