Abstract
A step counting device includes a top casing, a bottom casing, a display, and two operating buttons. A circuit board is arranged in the space between the top casing and the bottom casing. An open area is formed on the edge of the circuit board and a ceramic vibration detecting mechanism is arranged on the circuit board. One end of the ceramic vibration detecting mechanism is a fixed point located on a fixed position and the other end is a cantilever point extended to the open area of the circuit board and a heavy mass is attached to the cantilever point. The step counting device is attached on a shoe, and the step counting device will be vibrated while a user wears the shoes walking or running. The ceramic vibration detecting mechanism will receive the vibration and a tiny voltage change will be produced to become an input signal to the control circuit on the circuit board. Through counting, processing and exchanging the input signal by the control circuit, a step counting output signal will be outputted and a step number will be displayed on the display.
