Abstract

PURPOSE:To simplify a measuring device by obtaining the peak value or integral value of a voltage by detecting impulsive force, applied to a diaphragm, directly by a pickup provided at the back of the disphragm. CONSTITUTION:Impulsive force generated by colliding a ball, etc., is measured. For example, the impulsive force is applied to a diaphragm 5 whose circumferential edge is fixed to a frame 4 and an electromagnetic pickup 6 is provided at the back or on the back side of the diaphragm 5. This pickup 6, including a permanent magnet 13 and a coil 8, detects vibrations of the diaphragm 5 and the peak value or integral value of a voltage induced across the pickup 6 is measured by impulsive force evaluation device 20 to display the peak value or integral value on a display device 30.
