Piezo Buzzer Summer active

This practical active buzzer can simply be connected to a digital Arduino output and generate a signal. It is often used where a button press or confirmation should be signaled. Since this is an active buzzer, it produces a fixed frequency of about 2500Hz. The buzzer can also be operated with 3.3V, but be careful and first check whether your output can supply 15mA (do not connect directly to the ESP8266). The long pin on the buzzer is the + pole and the short one is GND.
