    I have very limited experience with electronic knowledge but had a question that was hoping to find some guidance on. I was wondering what I needed to record audio on that I could connect to a battery powered external speaker. For example, a weather proof single speaker that would be outside that could play my One to two minute audio by pressing a button. Any ideas would be a huge help. Thank you.

    Cassette audio recorder? Maybe you can get a deal on one at RadioShack...;)

    Even though that would be very practical I was thinking a little more hi- tech.

    I think it was a month ago that I was in a drugstore and saw a digital voice recorder. Very small, surprising amount of time available.

    Thanks for the reply... I guess I'm trying to go for more of a way I record on computer then be able to export into something that could be played on the external speaker minus Bluetooth. So lets say a speaker on a stake powered by battery playing my 2 min recording.

    I don't understand. Do you want to make sure the computer does not play sound through its speakers, into the voice recorder?

    I guess you would have to use the computer to make an MP3 file and load that into a portable MP3 player.

    Sorry, I just want to invent something involving a small speaker that people can walk up to hit a button an it plays audio that I have recorded. Like me telling a story.

    Too late. It's already been invented.

    These things have been in museums for decades.

    Ditto, the electronics portion as you describe it has already been done. If you want to buy a ready made module, take a look here. These modules will accept an audio file up to 200 seconds long (over three minutes, depending on quality desired) and play back with the push of a button. They include the speaker and batteries. Alternately, you can search eBay for recordable greeting card (module), but I'm not sure there are many that can record and playback a full one to two minutes of audio.

    If you just want a chipcorder to work with, a Google of Chipcorder will get you to nuvoton ISD ChipCorder devices.

    You can buy very small & cheap mp3 players. You can also buy battery powered amp-speaker combos or make your own.

    Thanks for the reply! This is the direction I wanted to go in now only to see if it can be weatherproof for spring, summer, and fall.
