Title:
音響変換器
Document Type and Number:
Japanese Patent JP6984009
Kind Code:
B2
Abstract:
A sound transducer, in particular for an ultrasonic sensor, is described, which includes a housing, at least one decoupling element and a functional group. The functional group includes a diaphragm cup and at least one electroacoustic converter element. The diaphragm cup includes a vibratable diaphragm and a circumferential wall as well as at least one electroacoustic converter element, the converter element being configured to excite the diaphragm to vibrations and/or to convert vibrations of the diaphragm into electrical signals. The diaphragm cup and at least one part of the housing are made from a plastic material. The decoupling element is configured to vibration-mechanically decouple the diaphragm cup and/or the at least one part of the housing from outer surroundings of the sound transducer. The decoupling element is integrated into the diaphragm cup, in particular into the wall of the diaphragm cup, and/or the at least one part of the housing.
