Vỏ đựng Micro tiếp xúc (Piezo Contact Microphone)

Just a small (5x5x1cm) Case for a 27mm Piezo Disk to use ist as a Contact Microphone.
In the bottom is a 15mm hole to glue a magnet in, which also is used to ensure a direct connection between the ground an the piezo disk. 

Additinal Material needed: 

• 15x3mm Magner

• 27mm Piezo Disk

• 4x 3x12mm Screws (holes are 4mm ists not strict)

• Cable with plug - XLR or TRS 

The Nuts are a bit loose in the bottom part - i used a flat screwdriver to hold the nuts while tightening the screws. 

Building: i just superglued the magnet to the piezo disk an than both into the bottom part. The cable get a strain relief through the curves.
