This is essentially an updated megaphone/bullhorn that also has a line input for music players.

This is a professional unit for playground to police use, and so it is probably better suited for field work than off-the-shelf consumer electronics items.

My preferred source is Markertek. They know their stuff and have at least a dozen items that might fill the need; this one seemed the best to me.

Good luck,

John

You will never get the db output you need to throw as far as you need
in a jungle over the top of all the jungle noise as well with home
loudspeakers

You have to have an efficient bullhorn/compression driver horn/ or this
unit Mark has posted would work well for you also

Dont forget the harsh climate you are gonna have this stuff in and you need
something that can handle the humidity/mold/moisture/heat etc

Best of luck and by all means have a good time in the jungle an bring
plenty of deet along!

Hi John,
Thanks for the speedy reply. Do you know anything about the sound quality of the bullhorn? I need quite good quality because I am trying to fool the animals into thinking that there is actually another animal producing the vocalization.

  I have no personal experience with that product. From my perspective, the fact that it runs on battery power, and is self-contained and not heavy are decisive advantages.
  
  Nearly all stereo loudspeakers are designed to be used indoors or in nearfield listening outdoors, e.g., rainproof loudspeakers meant to provide background music at cocktail time on the deck. So that means the listening distance is at most 15 feet, and not the length of a football field.
  
  I understand your requirement of natural sound. All I can suggest is that you discuss with Markertek the terms on which you can return it, and then take it to a zoo and see if it fools any primates.

  I don't have a product recommendation for you, but I do have a couple thoughts on animal sounds, birds in particular. You may be surprised at how much detail and variation there is in a "typical" bird sound. I've recorded a fair amount of them, and when I look at the waveforms, there's all kinds of stuff going on! I've come to believe that the "simple" sound we hear has much more meaning to the birds! Actually, this shouldn't be surprising. Our own vocalizations, without the details, are fairly monotonic. It's the details of the variations that make up our languages and give our sounds meaning.

    I agree completely! Part of what I study is the significance of small variations in bonobos' vocalizations.
