Description

Ultrasonic generating device having position recognition function and method for controlling the same The present invention relates to an ultrasonic generating device. More specifically, it relates to an ultrasonic generating device having a position recognition function of an ultrasonic generating element, such as a transducer, and a method for controlling the same. Generally, ultrasound refers to a wave that has a frequency exceeding 20 kHz and propagates by vibrating a medium. In some cases, it refers to sound waves exceeding 15 kHz. Due to its short wavelength, ultrasound can concentrate energy at an acute angle to impart directionality, resulting in high linearity. Furthermore, ultrasound possesses propagation characteristics such as reflection and refraction, and is widely utilized in various fields due to its recognized high safety and non-harmfulness. For example, ultrasound is used in industrial sectors such as sensors for detection or measurement, sonicators for the dispersion or mixing of substances, and cleaning. Other applications include ultrasound imaging, monitoring of heartbeats, the destruction of kidney stones, and cosmetic devices for skin stimulation.
