PROBLEM TO BE SOLVED: To provide a lamp device which is actuated without requiring installation work, and when receiving vibration, automatically turns on a light-emitting diode, and after lighting for fixed period, automatically turns off the light-emitting diode, and to provide a buzzer device which when receiving vibration by a vibration sensor, automatically allows a buzzer to sound, and after sounding of the buzzer for a fixed period, automatically stops the sounding.SOLUTION: A lamp device 1 includes a cathode connection terminal T1, an anode connection terminal T2, a microcomputer MC, a vibration sensor S, and a light-emitting diode D. A buzzer device includes a cathode connection terminal, an anode connection terminal, a microcomputer, a vibration sensor, a buzzer, an electrolytic capacitor, and a bipolar NPN transistor. |
