Abstract:
A pedometer for detecting vibrations in a direction of motion, comprising:a main body (10); a printed circuit board (20) incorporating a counting circuit (30) and being installed inside the main body (10); the counting circuit (30) being formed by a signal amplifier (31), a signal detection circuit (32), and a processor (33); a vibration detector (11) being installed on the printed circuit board (20) and connected to the counting circuit (30), wherein a sensing pad (110) of the vibration detector (11) is disposed orthogonal to the direction of motion to sense any body vibration in the direction of motion; wherein the vibration detector (11) comprises a ceramic piezoelectric element; and a display unit (12) being installed on the printed circuit board (20) and connected to the counting circuit (30) for displaying a pace count value; where the above vibration detector (11) is disposed orthogonal to the direction of motion and operates in conjunction with the counting circuit (30) on the printed circuit board (20) to detect any body vibration in the direction of motion.
