Passive Buzzers: Unlike active buzzers, passive versions require an external AC signal to produce sound, providing more flexibility in tone generation.
High-Frequency Buzzers: Known for producing sounds at higher frequencies, these buzzers are ideal for applications needing alert signals or alarms.
Low-Frequency Buzzers: These buzzers generate lower tones and are suitable for applications requiring audible but less piercing sounds, like notifications.
Piezoelectric buzzer has a wider range of applications
In terms of usage scope, this type of buzzer can be used for various products such as gas alarms, anti-theft alarms, speed alarms, navigators, car speakers, and car equipment.
Can produce a variety of sounds
Due to the fact that piezoelectric buzzers are controlled by electronic circuits, they can produce various pleasant sounds as well as simulated and intermittent sounds. The sound is pure and not easily covered by noise.
Can save electricity
Piezoelectric buzzers use voltage excitation, so the current consumption is small, generally below 20mA and not exceeding 100mA.
Advantages Of Active Piezo Buzzer
Have High Sound
Sound quality is one of the main factors to consider when choosing a buzzer. The active buzzer tone is relatively loud due to its higher sound pressure, making it more reliable.
Have High Sensitivity
In contrast, active buzzers are more sensitive. The active buzzer is easier to be triggered and makes a sound, which makes it more effective.
Have Low Power Consumption Rate
The power consumption rate is one of the main factors determining the operating cost of the buzzer. For how to make a piezo buzzer work at minimal cost, you need to consider its power consumption rate.
Highly Reliable
Compared to other types of buzzers, piezo active buzzers are very reliable because they require less power to operate. Therefore, the active buzzer will rarely applaud because of insufficient power. Moreover, it is easy to maintain.

Application of Piezoelectric Ceramic Buzzer
Sensors and Actuators: Piezoelectric ceramics find extensive use in sensor technologies, such as pressure sensors, accelerometers, and strain gauges.
Energy Harvesting: The ability of piezoelectric ceramics to convert mechanical energy into electrical energy makes them valuable for energy harvesting applications.
Medical Imaging: Ultrasound imaging heavily relies on the piezoelectric effect of ceramics to generate and receive ultrasonic waves. Piezoelectric transducers are crucial components in medical ultrasound systems, allowing for non-invasive imaging of internal body structures and aiding in diagnostics.
Industrial Applications: Piezoelectric ceramics are employed in industrial settings for precision positioning, flow and pressure control, and vibration damping. They contribute to improving manufacturing processes, ensuring accurate measurements, and enhancing overall efficiency.
Application of Active Piezo Buzzer
Consumer Electronics: Commonly found in smartphones, tablets, and appliances for alerts and notifications.
Medical Devices: Used in equipment for alarms and alerts, enhancing patient safety and care.
Automotive Industry: Integrated into vehicles for seatbelt warnings, alarm systems, and various electronic notifications.
Employed in machinery for warning signals or operational notifications, crucial for workplace safety.
Piezoelectric Ceramic Buzzer Structure
Piezoelectric Disc
Typically made of specialized ceramic material like lead zirconate titanate (PZT), this disc generates sound waves when subjected to an electric field, causing mechanical vibrations.
Metal Plates
These plates, often made of brass or stainless steel, serve as electrodes to transmit the electric signal to the piezoelectric material. Their size and shape can vary based on the buzzer's size and output.
Housing
Some piezo buzzers include housing, often plastic or metal, to protect the components from damage. The housing's design depends on the intended use of the buzzer.
