Membrane tension measuring device |
| abstract |
Membrane tension measuring device, comprising: - a rectangular frame (5) which can be placed against a surface (4) of a membrane (2), a voltage being applied to the membrane (2); - an acoustic wave generator (17) which is mounted on the frame (5) and which is a flat speaker with a flat plate (20) placed parallel to the part (2a) of the diaphragm (2) on which the frame is applied and emits an acoustic wave to the part (2a) of the membrane (2) surrounded by the frame (5); - a vibration detector (24) which is mounted on the frame (5) and which is designed to detect the vibration induced by the emitted acoustic wave in the part (2a) of the membrane (2); and - a processor (29) which is attached to the frame (5) and is designed to calculate the tension based on the vibration data detected by the vibration detector (24). |
