This increased drive voltage results in a louder output sound from the buzzer while using the same supply voltage. Many versions of both half-bridge and full-bridge drivers are available as inexpensive integrated circuits and are often used to drive electric motors.

This article covers the advantages and disadvantages of several common driver circuit design techniques for piezo transducer buzzers. Piezoelectric transducer buzzers are a well-known option for audible identification and alert between a product and its user, but unlike their indicator counterparts, transducer buzzers require an external driver circuit to produce a …

Hi Moboy, yes it is possible to drive a piezo element directly through a IC 555 astable, by connecting the piezo wires across pin3 and ground, but you will also require a small 100uF inductor parallel with the piezo wires for proper amplification, an the frequency will also need to be adjusted to suit maximum volume.

https://www.maximintegrated.com/en/design/technical-documents/app-notes/9/988.html
Abstract: This audio application note identifies and describes the key elements in designing a driver for a piezoelectric transducer (PZT). The relationship between source impedance and sound pressure level is measured, single-ended (S/E) and bridge-tied load (BTL) driving schemes are compared and the input impedance of a PZT is characterized. Audible piezoelectric …

There are two possible ways to excite the audible PZT to produce sound; by driving it with a single- ended signal (i.e., 0V to +5V) or with a bipolar signal (i.e., -2.5V to +2.5V). Figure 2illustrates the mechanical deflection about a midpoint of mechanical zero when an audible PZT is driven with a bipolar signal.

For instance, an actuator/motor specifies 40V peak voltage, but a lab signal generator can only output is 5V or less. To achieve 40V square-wave, a piezo amplifier driver is used to boost the generator signal and outputs high voltage and high current to drive the piezoelectric actuator. Figure 3 shows an example of a piezoelectric transducer driver. Note …
