An ultrasonic horn is a device that amplifies and transmits high-frequency sound waves, typically between 15 and 100 kHz, generated by an ultrasonic transducer. The horn is designed to efficiently transfer the vibrational energy from the transducer to the material being processed, such as welding, cutting, cleaning, or bonding.
The ultrasonic horn is usually made of a metal alloy, such as titanium or aluminium, which has high acoustic conductivity and low damping. The shape of the horn is carefully designed to match the acoustic properties of the transducer and the material being processed. The horn may have different configurations, including a booster horn, a sonotrode, or a horn stack.
Ultrasonic horns are widely used in various industries, such as automotive, aerospace, medical, food, and electronics. They offer several advantages over traditional mechanical or thermal processing methods, including high precision, low energy consumption, and non-contact processing.
