Operation, the not readily portable instant demonstration carried out into classroom during classroom instruction, and it is single to measure function, can only use
One sensor measures, so as to cause student preferably to grasp principle and the side of piezoelectric transducer vibration measurement
Method.The invention of handheld piezoelectric sensor vibration measurement experiment platform, helps to carry conveniently during class-teaching of teacher, is saying class hour more
The principle and method of piezoelectric transducer vibration measurement are vivo shown to student.
Utility model content
In order to overcome existing sensor laboratory table measurement method single, observation is not directly perceived enough and cannot be given immediately on classroom
The defects of student demonstrates, passes through small-sized integrated the utility model proposes a kind of handheld piezoelectric sensor vibration measurement experiment platform
Change design, using transparency protected babinet, carry out vibration measurement using piezoelectric ceramics or piezoelectric film sensor, realize class-teaching of teacher
When can conveniently carry during the experimental bench carries out classroom instruction to classroom immediately demonstrating.
Technical solution is used by the utility model solves its technical problem：Using manually tap piezoelectric membrane or
Press piezoelectric ceramics and produce vibration electric signal, ensure the output of only sensor signal using double-point double-throw switch, using turning
The vibration electric signal that fishplate bar will detect, connects usb data capture card by preamplification board and is transferred to computer, and then is throwing
Real-time display on shadow instrument.By the way that lithium battery, piezoelectric membrane, piezoelectric membrane pinboard, piezoelectric ceramic piece, piezoelectric ceramics are transferred
Plate, double-point double-throw switch, preamplification board and usb data capture card all functions component are integrated into a small-sized transparent experimental bench
In carry conveniently when realizing class-teaching of teacher.
The beneficial effects of the utility model are：By lithium battery, piezoelectric ceramic piece, piezoelectric ceramics pinboard, piezoelectric membrane, pressure
Conductive film pinboard, double-point double-throw switch, preamplification board and usb data capture card are integrated in a small box body and improve
The portability of experimental bench；The transparent babinet of design is easy to the composition and experimental result of student's direct-viewing system on classroom.
