Summary: Explanatory note diploma project on "device for sound reinforcement bandura" volume 56 pages contains 24 illustrations, 8 tables, 2 addition and 7 applications bibliographic titles for references. The aim of the diploma project is to develop a portable device pickup and sound reinforcement bandura, to ensure the functioning tures which do not need to interfere with the design tool. The project analyzed the design bandura and methods of removing the sound of acoustic instruments selected optimum pickup and circuit gain with frequency compensation scheme of electrical structural and fundamental instrument, designed PCB and printing unit and conducted calculations confirm performance of the device, including: reliability, mechanical testing. In the section "Occupational Safety" is estimated major potentially harmful and dangerous factors that play a role in the design, manufacture and operation of the designed device.

Keywords: bandura, pickup, piezoelectric, power, printed circuit board.

The work consists of  58 pages of explanatory note, 2 appendix and 5 drawings
