Abstract
Description
Acoustic electronics
Fighting harmful tidal waves using tiger cry
Harmful tidal control system using only very low frequency signals among tiger cry
Using a frequency extractor and a low pass filter to extract the bass frequencies from the crying tiger and amplify the signal with a digital amplifier
It is effective in combating harmful tides without disturbing human ears.
Only the ultra-low frequency components below 18 (Hz) except the 20 ~ 20,000 (Hz) component, which is audible to human ears, of tiger crying from Gyeongsang National University Bio-acoustic bank, are frequency extractor or low pass filter (LPF). After extracting only the animal extermination sound signal component by using, store the extracted animal extermination sound signal in a memory such as ROM, and control the memory where the extermination sound is stored by using microprocessor, and consists of digital amplification circuit, power circuit and timer circuit. And reproduce through a speaker.
Conventionally, the problem that the tiger cries are greatly heard through the speaker is also improved, so that only the signal components that can only be felt by animals are reproduced through the woofer speaker, and the digital amplification output circuit of the eradication device is configured by 4CH. In case of connecting only signal line at the stage, installation of four speakers has widened the operating radius to improve practicality and efficiency.
