In Japan, there is a finger-size alarm that can emit an alarm sound of up to 130 decibels when the plug is pulled out. It seems very interesting. What role can it play?
For some reasons you know, Japanese women have been far more likely to be harassed than other regions. On the one hand, traditional self defence devices, such as pepper spray, electric shock device, anti-defence ring, etc., are not convenient to use when they are not sure whether the other party will have further misdeeds.
On the other hand, women who know kungfu like Maolilan are rare in reality. So the best way is to sound the alarm to attract others’ attention. In fact, if you think about it carefully, this alarm is still full of “positive energy”. For example, when you see the thief is about to succeed on the road or on the subway, you will press the alarm quietly next to him, and the bad guys will be scared to death. Both adults and children can wear it at any time.
With AAA battery power supply, the continuous sound can last for 6 hours. Of course, the actual use is longer.
