The main difference between electromagnetic actuators and piezoelectric actuators lies in their driving frequencies.
Electromagnetic actuators operate at a single frequency, typically below 500 Hz, whereas piezoelectric actuators can be driven across a wide range of frequencies, from low (1 Hz) to high (up to 40 kHz).
TAIYO YUDEN’s piezoelectric actuators offer a range of driving frequencies tailored to different applications.
Examples of Piezoelectric Technology Applications
Piezoelectric technology has revolutionized various industries with its ability to convert mechanical energy into electrical signals and vice versa. Below are some innovative applications of this versatile technology:
Automobile Cockpit Components
​
Piezoelectric actuators enable precise haptic feedback in touch panels and control systems, enhancing the user experience with responsive tactile sensations.

Innovative Speaker Systems
Piezoelectric speakers can offer a compact, lightweight, and energy-efficient alternative to traditional electromagnetic speaker delivering clear, high-frequency sound with minimal distortion. Ideal for specialized applications such as ultra-thin speakers in smart devices, wearable audio products, and so on.
Communication Devices with Wireless Tactile Transmission
​Piezoelectric technology's advanced wireless tactile feedback capability allows users to experience real-time, tactile sensations when interacting with devices, enhancing the user experience in smartphones, gaming controllers, and other consumer devices.
Bone Conduction Headsets and Hearing Aids
Bone conduction devices can use piezoelectric actuators to send vibrations directly through the bones of the skull to the inner ear, allowing users with hearing impairments to enjoy clear audio while keeping their ear canals open, providing both comfort and situational awareness.
