PURPOSE:To obtain the electronic wristwatch with the accelometer having a simple constitution, by displaying the acceleration signal through a magnetism sensitie switch which responds to the locus of the tip of the pendulum formed by a permanent magnet. CONSTITUTION:The magnetism sensitive switch elements 31-34, which respond to the locus of the tip of the pendulum 2 formed by the permenant magnet of an acceleration detecting circuit 1, are provided in an symmetrical arrangement. The time interval between the detected outputs of said elements are measured by a measuring circuit 8 based on the oscillating frequency of a crystal oscillator 9. Based on said measured values, a computing circuit 10 computes the acceleration, and it is displayed on the display part 13 through a decoder 11 and a driver 12. Thus the electronic wristwatch with the accelometer having the simple constitution is obtained. |
