Description
technical field [0001] The invention relates to a wave detection system, in particular to a loss suppression type high-frequency conversion wave detection system with low calorific value. Background technique [0002] The detector can detect some useful information in the fluctuating signal. It is a device used to identify the existence or change of waves and oscillating signals, and can also be used to extract information carried by the outside world. At present, the geophone has been widely used, for example, it can be used in geological exploration and engineering survey, and it can be used to measure the noise when the equipment is running, which brings great convenience to people. [0003] However, the current temperature of the geophones on the market is too high when they work, which is not conducive to the long-term work of the geophones. Contents of the invention [0004] The purpose of the present invention is to overcome the defect of high temperature when the ...
