Ultrasonic Focused Transducer
A high-performance acoustic driving device based on piezoelectric ceramic technology, converting high-frequency electrical energy into high-intensity focused ultrasound (HIFU) for targeted energy delivery through precise electro-acoustic energy conversion and focusing. Its core function is to generate controlled acoustic pressure pulses that produce high-energy shockwaves or thermal effects in specific focal zones, widely used in medical therapy, industrial inspection, and scientific research, particularly excelling in non-invasive treatments (e.g., lithotripsy, pain management).
