Hello DIYers,
Are there any ready-to-use vibration sensors/accelerometers available? I would like to use one for the analysis of panel vibrations, and for planning and executing effective vibration control. I like to be proactive about design planning to determine if there is an improvement to be made before advancing to the to next stage of the design.

You can get small accelerometer boards with analog outputs. Power them from a few AA batteries and use them with Line/Mic in of a soundcard. They're available from ebay and others for <$10. The one shown below is the cheaper +/-3G model. Usually vibration analysis results in high G short duration signals but the ADXL335 may be enough to indicate cabinet improvements.

Hi perrymarshall,
What exciters did you have in mind? I was reading about people converting microphones for this purpose, but my hopes are to use a device that responds to surface vibration while not being sensitive to acoustic noise.
Hi DonVK,
Certainly interesting, and I will take a look at these now.
Use exciters like this one as microphones instead of speakers: https://www.parts-express.com/Dayto...m-2-Hole-Exciter-24W-4-Ohm-295-225?quantity=1
