  • Bass sound generator

    Hello everyone!! First time posting here!!
    Basically, what I am doing, is making some props to produce and sell(don't want to say what it is just yet).
    But essentially, I am using 2 puck transducers to create a rumble effect. They are low power transducers, so I have a 2x20w amp powering them.
    The only problem is, what can I use as an audio source?? There are plenty of signal generators or pieces of software out there, but those aren't really what I need to assemble and sell props.
    What I am looking for is some sort of small electronic device, that simply outputs a low frequency tone (20hz to 200hz range) to make the transducers shake.
    I am trying to keep it as low cost as possible, as I am trying to keep the cost of the props down for customers. I already have about a dozen people wanting these props, so it preferably needs to be something I can just wire into the amp and go.
    Also, I plan on running the amp and whatever I use to generate the tone, and a couple other small devices on the prop, through a common switchable power source. So basically, I can set it up to flip one switch, and everything comes on at once. So using something like a cheap MP3 player would not work. I need it to output the tone as soon as power is applied.
    Anyone have any ideas???

    How about this?

    And you can create your tone in Audacity ...
    You can get it from audacity.sourceforge.net I made a 33Hz file, but it wouldn't let me upload it. I will leave instructions instead...Once in Audacity, click "Generate" then "Tone" then select "Sine" and set the tone to 33Hz and the duration to whatever you want. Click "File", "Export as WAV".

    That should do it.

      Check out these guys as well, call them and tell them your needs- since all you need is a sine wave I bet a servo controller could do it too.

      If you want to try the servo route Ive had great success with

        We sell Gilderfluke SD-10s and they begin playing as soon as power is applied. Let me know if you have any interest.

          Cool you know Pololu - I had them laser cut a grid of holes into plexi like five years ago - when I was in Vegas last I planned to go see the shop but was overbooked. They are great people and will deliver exactly what they say they will.

            i know Im going off topic here, but I love their micro maestros- it controls six servos in a repeating programmable pattern that happens automatically at start up. awesonme. I have about six of them working for me in my museum.
