How does insect repellent work?
An active ingredient whose natural or synthetic chemistry is not within certain ranges is the way insect repellent works. The active ingredient may be citronella, DEET, geranium oil, lemongrass, oil of lemon eucalyptus, peppermint oil or soybean oil. Insects such as mosquitoes and ticks seek carbon dioxide or lactic emissions, certain colors and specific temperatures from their unwilling human hosts, whose vulnerability is lessened by being protected by oils or sprays whose lab- or Mother Nature-made contents are deemed repulsive to breeding and feeding.
How do the ultrasonic input signals should be given to the loudspeakers to produce ultrasonic sound's explain the mechanism of working?
It works just like any other input signal (you know, the changing current moves an iron slug connected to the diaphragm of the speaker). The trick is to use a speaker with a small enough diaphragm to respond to those high frequency signals. ADDED. An ultrasonic loudspeaker is more likely to be piezoelectric than moving-coil in action, especially much above about 20kHz.
