A piezoelectric fan assembly includes a case defining an air outlet, a fan arranged in the case, and a guide plate mounted in the case and encircling the fan. The fan includes a mandrel positioned in the case, two swing members mounted to the mandrel and each including a piezoelectric element, a circular connecting portion connected to the at least one swing member, and a number of fan blades mounted to the connecting portion to generate airflow by the swing members in response to the piezoelectric element receiving alternating current power. A wind channel is formed between the case and the guide plate. A number of openings are defined in the guide plate corresponding to the fan blades. The guide plate is to transfer airflow from the number of fan blades to the air outlet via the wind channel, through the number of openings.
