Cheap Alternative External Speaker for Dogtra Electronics

[copterdoc]

I just ordered a few of these. http://www.parts-express.com/pe/show...r=267-7054&utm
Way cheaper than $40.

I'll post a thread in the reviews section after I've used them a few times.

Thanks and please DO let us know if they work. For this price, I think I'll get some.

I got them today, and they DO work!

It's plug and play.

I measured the RR Deluxe internal speaker's output with a Radio Shack SPL meter, and compared it to what I get with the Pyle 5" external speaker.

Here's the measurements from 4 feet away.

Internal duck = 91 Db.
Internal beep = 93 Db.


External duck = 102 Db.
External beep = 110 Db.


The thing that you need to understand about Sound Pressure Level measurements, is that it's a logarithmic scale.
Every 3 Db increase, is double the volume.

So, this external speaker isn't just a little louder.
The duck is over 10 times louder, and the beep is over 50 times louder.

The beep actually hurts my ears.

CD, I've read stuff in the past about the use of an MP3 player hooked to a device like this for use as A) An electronic calling device for conservation order snow goose calling. B) A better way than a boom box to play the Guns Up CD or other Field Trial simulation sounds for training.

Are you enough of a RadioShack type geek to suggest what components to put together to make that work?

Let's say, for example I have the MP3 player already. Can I plug this straight in, or do I need an amplifying device as well? Any ideas?

I found this on Youtube:



I'm thinking an amplifier is needed. I'm wondering if this is a valid replacement for car stereos and boom boxes for the Guns Up CD.

You could plug it right in, but you are correct that it wouldn't be very loud without a separate amplifier.

The PA horn speaker that I linked to, has a power handling range of 15 to 25 watts.
Less than 15 watts, would not produce much sound. More than 25 watts, would damage the speaker.



The biggest issue with using an mp3 player for this application, is how do you trigger the sound remotely?

I wish this kid listed part numbers or sources for the stuff. The amplifier I can not find with the searches I've done.

I get it on activating the mp3 player. You'd pretty much have to be right there to push the button. Regarding the Guns Up, obviously that would be converted from your purchased CD onto an MP3 file.

Yeah, I haven't ever seen one.

Usually the speakers themselves contain the amplifier.
Or there are iPod docks with built in amplifiers.

You know, I bet a CB geek would know where to find one.

Here's one. But they are out of stock.
