Description

technical field [0001] The invention relates to a vibration detection device, in particular to an earthquake alarm instrument. Background technique [0002] About 5.5 million earthquakes occur around the world each year. It can cause fires, floods, toxic gas leakage, bacteria and radioactive substances, and may also cause secondary disasters such as tsunamis, landslides, collapses, and ground fissures. Because earthquakes are difficult to predict accurately and occur at random times, they often cause a large number of casualties and property losses. [0003] Zhang Heng, a scientist in the Eastern Han Dynasty in my country, made the world's earliest "seismograph" as early as 132 AD. Although there are many early warning and alarm devices for earthquakes, due to its complex structure and relatively high cost, it is not easy to use it. Be popularized. Contents of the invention [0004] Based on this, it is necessary to provide an earthquake alarm instrument with simple stru...
