ABSTRACT:
An ultrasonic device includes a coupler, a mounting sleeve and an exponential horn form by both the coupler and the mounting sleeve. A flange is located on the mounting sleeve for support at a node of minimum vibratory motion. The mounting sleeve and coupler are formed separately and then metallurgically attached so they vibrate together as a substantially unitary member. The formation of the horn by the two components in this manner allows the diameter at the start of the horn to be increased to the outer diameter of the mounting sleeve, thereby increasing cross-sectional area at the horn start and increasing amplitude at the horn tip. Preferably, the coupler and mounting sleeve are made from stainless steel alloy and attached using a silver braze alloy. The device may also include a support collar attached to the mounting sleeve flange to support the mounting sleeve and primary coupler.
