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

I used this in circuit with the Kemo Ultrasonic Signal Generator Module. Speaker worked as advertised. I'll probably end up configuring an amplifier and a higher Wattage / dB speaker set up. It definitely produced some annoying frequencies to try and hinder dogs from barking.

It delivers high frequency

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.

This sounds very quiet, maybe it needs more than a couple watts drive?I have some smaller ones that are much louder.

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

Seems to work for barking dogs. Would recommend and I even bought a 2nd.

el producto es como se especifica

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