In the thesis, we focused on designing a device for measuring vibrations based on a piezocrystal and evaluating both this device and the piezodisk itself. First, we designed and assembled an amplifier, then we designed a suitable casing, and finally, we conducted measurements on the piezocrystal and the speaker. The measurements were performed with manual excitation and using a vibration generator at different frequencies. With the basic amplifier design we successfully achieved singal amplification, performing best at lower
frequencies.
