A METHOD OF MANUFACTURING A TRANSDUCER HAVING A DIAPHRAGM WITH A PREDETERMINED TENSION |
摘要 |
A method of manufacturing a transducer of the type having a diaphragm (11) with a predetermined tension. After the transducer has been manufactured wit h its basic structure the diaphragm is adjusted to have a predetermined tensio n, which is preferably low in order to obtain a high sensitivity. Two embodimen ts are disclosed. One embodiment includes heating the transducer to a temperatu re above the glass transition temperature of the material (12, 14) retaining th e diaphragm. Another embodiment includes measuring the actual tension of the diaphragm, which can be used to calculate an adjustment of the thickness of the diaphragm resulting in the desired tension. |
