Piezo Spherical Dome Tweeter with Flare (L001) for ultrasonic Sound Generator M048N

Solved my raccoon problem

I used this speaker to make an anti-barking device and it did the job that I needed. Work great on high-frequency sounds.

I purchased this speaker with the Kemo 40watt amplifier.I tested frequencies from 3000-15000 hz, and a pin drop is 100x louder than this “speaker” and amp combo.Do not waste your money on this Kemo amp and this speaker. It is worse than useless. Money down the drain.

Yapping dogs at all odd hours of the night, barking at who knows what .. Pigeons cooing in the wee hours of the morning. -I paired this a KEMO M048N UltraSonic Generator and a Headphone Amplifier. I removed the cone, and added a 3" polished ABS tube in-front, and it acts like a Sound Cannon :-P

Seemed to work fine for high frequency sounds and we noticed it stopped having an effect on the animals I was using it for. I checked the back of the speaker and part of it had come unglued and was hanging freely from it's two connecting wires. Completely useless after a day of light use.
