Method for manufacturing an ultrasonic transducer |
摘要 |
An ultrasonic transducer includes: a diaphragm pot that has a surrounding wall; a transducer element mounted in a diaphragm pot on a transducer section on an inner side of the diaphragm for generating the ultrasonic vibrations; a first damping element situated in the diaphragm pot on transducer element for damping the diaphragm; and a second damping element situated within the diaphragm pot in an edge section of the diaphragm around the transducer element for damping vibrations of the wall; the second damping element being connected with force locking, at least section by section, both to the edge section and to the inner side of the wall. |

1. A method for manufacturing an ultrasonic transducer having:
a diaphragm pot having a surrounding wall and a diaphragm; a transducer element; a first damping element; and a second damping element, the method comprising:
inserting the second damping element into the diaphragm pot, the second damping element being connected in a force-locking manner to an inner surface of the surrounding wall of the diaphragm pot and to an edge region of an inner side of the diaphragm in the diaphragm pot;fitting the first damping element into a through hole of the second damping element,removably mounting, before the insertion of the second damping element, a core having the shape and the dimensions of the first damping element on the transducer element, wherein the second damping element is introduced as a castable material into a region between the core and the inner surface of the surrounding wall of the diaphragm pot; andremoving the core to form the through hole, after the curing of the second damping element. |
