Description

This sales item is an .STL file for 3D printing of a plastic horn to increase the distance for 1D tracking for up to 100m or more. Note, the microphone is not included and shall be purchased separately.

The horn can be shipped already printed – not as an STL file. In this case, the order shall include sales item Shipping & Handling fee (Complexity I).

The horn is perfectly tuned for the External Microphone-IP67 and is designed to be used along with Super-Beacons and Mini-RXs as ultrasonic receiving beacons. See more about external microphone: https://youtu.be/FwH-ScrTnm8.

Typical configurations for 1D tracking:

  • Beacons HW v4.9 (TX) + Super-Beacon (RX) & Horn (RX) + Modem HW v4.9
  • Beacons HW v4.9 (TX) + Mini-RX (RX) & Horn (RX) + Modem HW v4.9
  • Super-Beacon (TX) + Super-Beacon (RX) & Horn (RX) + Modem HW v4.9
  • Super-Beacon (TX) + Mini-RX (RX) & Horn (RX) + Modem HW v4.9
  • Industrial Super-Beacon (TX) + Super-Beacons (RX) & Horn (RX) + Modem HW v4.9

Instead of Modem HW v4.9, Super-Modem can be used.

Recommended ultrasonic frequency for the TX beacon is 25kHz or 19kHz. Range is decreasing with higher frequency. External noise is increasing with lower frequency. Optimal is 25kHz based on our experience, which is perfect for the Industrial beacons as well.

Many RX beacons can be used as in a regular system. But they must be within the ultrasonic beam defined by the horn, which around 20 degrees.

This is an RX horn. Separately, you can order a TX horn as well that would increase the distance even further or it would make the tracking even more confident in noisier conditions. Notice, that TX horn requires additional transducers to be shipped. Thus, it is not a purely .STL file. Contact us fore more details at info@marvelmind.com.

Please, notice that the attached oscilloscope graphs show results with a 50m-shift. Instead of trigger on 50m, it is trigger on 50+50=100m.
