Mini Piezoelectric Tweeter

small but mighty

I hooked just one of these up to a Kemo M071N as they are for a project I have planned. I adjusted the frequency and didn’t know whether to cover my ears or turn the frequency up to a n ultrasonic sound that humans cannot hear. These are tiny little speakers and I wasn’t expecting that level of sound to come out . So I am very happy and they should work well in my new project. I have/had these sparrows coming back for the last three years and they look in my window and chirp. To say it drives me nuts is an understatement and I really didn’t know what to do. I should say that one of them is now deceased as I accidentally hit it with my catapult knocked him of the roof and then had to break its neck to put it out if it’s misery, well after I played with it for a while for all the torment it’s caused me. Its mates will be getting the ultrasonic treatment and so will my neighbours dogs as they leave them caged barking howling and screaming for hours on end so I’m looking forward to that as I am planning to put one speaker in each corner of my roof so I can get anything from anywhere. I say anything as this includes my other neighbours kids. They scream and shout and blow whistles to the loudest of their ability as they are encouraged by there parents as I have hypersensitivity to certain sounds due to a brain injury. So this summer is going to be a reverse of the last three where I have been tortured to the extreme and I am going to enjoy every moment of them running in crying as they cannot deal with the noise. Whereas I won’t be able to hear it due to my age although their parents will and as I said the other sides four fat dogs that are never walked will and I hope they enjoy it as much as I have the barking and the whistling and chirping. I can’t wait. Revenge they say is sweet. Thank you for my new toys.
