Why are piezoelectric buzzers in demand?

Piezoelectric materials produce electric signals when under mechanical stress. The process is reversible, that is it can produce mechanical output if electric signal is given as input. When electrical signal is given to these materials, they change their shape slightly. Let us dive into more details about this amazing part of machinery. 


What is a piezo buzzer? 

As the name suggest piezo buzzer is an electronic product that is used to produce a tone, alarm or buzz. Its light weight and simple in construction and low cost. Depending on the piezo ceramic buzzer specification its highly reliable and can be used in wide range of applications in varying sizes & frequencies. 

Our piezo buzzers offer high sound output, also as they can be mounted on circuit boards they can be used in wide range of applications & assemblies. All our prices are highly competitive with fast delivery time. 


How is piezoelectric buzzer used? 

The piezoelectric property was discovered by Pierre Currie & Jacques in 1880, when they found that some of the materials when applied with electric signals can produce mechanical output and vice versa. 

When a piezoelectric material is subjected to alternating current, it stretches and compresses in sequence with the frequency of current and hence produces and audible sound. 


Piezoelectric buzzer work in a voltage range of 3-250 V unlike magnetic buzzer which has a narrow operating range of 1-16 V. The power consumption also piezo buzzers are less than 30miliamperes, even at higher frequencies whereas for magnetic buzzer it may range from 30mA –100mA. These are some of the primary reasons why piezoelectric buzzer is preferred over magnetic buzzers. 


Applications Of Piezo Buzzers

Piezo buzzers are flexible and reliable due to which they produce monotone buzz to multi tone alarms hence they find huge application in small & high-density applications. Due to their low power consumption, they can be easily used in batter operated devices. So, in short, they are used in applications like alarms, warning devices & automobile alerts. Their wide range of audible signals find them applications in pest controlling devices. They also are used in computers, toys, games etc.


Audible Sound Transducers

Also called tone generators, these simple, compact, reliable piezoelectric audible sound transducers can produce high sound output from a small energy input. They are widely used in battery operated devices, timers, smoke alarms, telephone ringers, metal detectors etc.

Audible sound transducers consist of a thin disk of piezoelectric ceramic bonded to a thin metal diaphragm. When voltage is applied to the ceramic disk it deforms causing the metal diaphragm to bend and produce sound. Likewise, when a recurring voltage is applied to the ceramic disk the metal vibrates at frequency equal to the applied voltage and produces sound. The maximum sound is produced when the mechanical resonance frequency of the metal matches the frequency of electric signal applied.

The future Of Piezoelectricity

The piezoelectricity is an interesting part of nanotechnology and many tests are underway to harness its power in full form. If used well and in right direction piezoelectricity will be another technology with which we can reduce our dependency on fossil fuels to produce the amount of energy we need.

The Benefits of Using Custom Battery Packs in Industrial Applications

By Swetha Parvathy • September 25, 2025
In industrial applications, battery power is often the backbone of operations, providing reliable and efficient energy to critical systems. While standard battery packs may suffice for some uses, custom battery packs offer unparalleled benefits for industrial applications that require specific power solutions. In this blog post, we’ll explore the advantages of using custom battery packs in industrial settings and how they can enhance performance, safety, and efficiency. What Are Custom Battery Packs? Custom battery packs are tailored battery solutions designed to meet the specific needs of a particular application. Unlike standard battery packs, which are mass-produced for general use, custom battery packs are engineered with precise specifications, chemistry, and design to fit the unique requirements of an industrial application. This customization allows for optimized performance, safety, and longevity. Benefits of Custom Battery Packs in Industrial Applications 1. Optimized Performance Custom battery packs are designed to deliver the exact voltage, current, and power output required for a specific application. This ensures that the battery performs at its best, providing consistent power and reducing the risk of underperformance or overpowering, which can damage equipment. 2. Enhanced Safety Industrial environments can be harsh, with extreme temperatures, vibrations, and other factors that can affect battery performance. Custom battery packs can be designed with safety features such as overcharge protection, thermal management, and ruggedized enclosures to ensure safe operation in demanding conditions. 3. Increased Reliability Reliability is crucial in industrial applications where downtime can lead to significant losses. Custom battery packs are built to meet the specific reliability needs of an application, ensuring that the power supply remains consistent and dependable, even in critical situations. 4. Longer Lifespan By selecting the right chemistry and design for a custom battery pack, manufacturers can significantly extend the lifespan of the battery. This reduces the need for frequent replacements, lowering maintenance costs and minimizing disruptions to operations. 5. Space and Weight Optimization Custom battery packs can be designed to fit within specific form factors, allowing for more efficient use of space in industrial equipment. Additionally, by optimizing the battery design, weight can be reduced, which is particularly important in applications where portability or weight distribution is a concern. 6. Flexibility and Scalability Custom battery packs offer the flexibility to adapt to changing application requirements. Whether it’s increasing the capacity, changing the form factor, or integrating new technologies, custom solutions can be re-engineered to meet evolving needs, making them a scalable investment for the future. Applications of Custom Battery Packs in Industry Custom battery packs are used in a wide range of industrial applications, including: - Material Handling Equipment: Forklifts, automated guided vehicles (AGVs), and other material handling equipment often rely on custom battery packs for reliable and efficient power. - Industrial Automation: Robotics, conveyor systems, and other automated equipment benefit from custom battery solutions that provide precise power and durability. - Medical Devices: Custom battery packs are essential in medical devices where safety, reliability, and longevity are paramount. - Energy Storage Systems: Custom battery solutions are used in energy storage systems to optimize power output and efficiency for industrial and commercial applications. Conclusion Custom battery packs offer significant advantages for industrial applications, from optimized performance and enhanced safety to increased reliability and longer lifespan. By investing in custom battery solutions, manufacturers can ensure that their equipment operates efficiently and reliably, reducing downtime and maintenance costs. Whether it’s for material handling, industrial automation, or medical devices, custom battery packs provide the tailored power solutions needed to meet the demands of modern industrial applications.
