Piezo Loudspeaker for Ultrasonic Power Cannon (M161) Kemo part L010

I used this to build a dog death star for my annoying ass neighbors and there dogs. The dogs bark at 2 am and the neighbors haven't a care in the world. I tell them it's a issue and I get " me no a speak a English " . Ya actually they speak perfect English just playing there games.Now I use this speaker with a ultrasonic pulse generator. I have one that's set just out of human hearing for the dogs and one set for human annoyance for the neighbors! It's the most terrible thing I've ever heard and the speakers are pointed right at them its awesome!Since then a month went by and now we all speak perfect English!! The dogs are still annoying and so are tge neighbors but at least we're speaking the same language now 🤣

The media could not be loaded. I'm using these in conjunction with a KEMO ultra sonic generator to help distract an otherwise non-stop-barker. Works really well. The video shows them mounted in a 3D printed housing. These seem nicely made, too.

This thing produces nice loud sound with my 1..150KHz square wave generator. Audible sounds are nice and loud even below 1000Hz. My ultrasound receiver and the neighbors dog shows that it puts out strong well into the 40KHz range.

Was hoping it was louder but still worked ok

If you have neighbors that don’t care how much their dogs bark and disturb your peace and quiet. This is what you need buy the power Canon M 161+ this piezo loudspeaker follow the instructions and it will stop the obnoxious barking, it really works ! I was amazed ,I tried other ones they all failed.They claim it has a range of 300 m and I believe it , I know it works real well in the range of 100 to 150 m ,they just stop barking it doesn’t make a sound and neither do the dogs ,I love it !! I bought another one for backup!

When added to a cone for directed sound, it works pretty good to ward off pests and annoying people.

Ultrasound to stop dog barking. It didn't work. Dog continued barking. It's a waste of money.

used two of these as part of my neighbor dog barking repellent. They seem to do the trick
