A pick up device acts as a transducer that captures

Guitar pickup works by the principles of magnetic induction and the quarter inch plug that runs from the amplifier to the guitar is electrically wired to the pickups. The pickups themselves are composed of small electromagnets that are small magnets with a coil of wire wrapped around it. These small magnets produce a field in their immediate vicinity, and thus induce a north and south pole on the actual guitar string. When the string is struck by the guitarist, it begins to oscillate. These oscillations affect the field in the vicinity of the pickup magnet and it induces a change in the flux of the magnetic field. These guitar strings are primarily made of steel, and the heavier strings would be nickel wound. On a normal six string electric guitar, the heaviest three are wound and the lightest three are single strands as these ferromagnetic substances that are guitar strings move within the magnetic field of the permanent magnet and it causes the flux through the bobbin to change. As this bobbin is such an excellent conductor and the change in the magnetic flux is opposed in the bobbin by the induction of an alternating current. The change in magnetic field that is created from the alternating current that is opposite to that of the change in the magnetic field in the bobbin and this is created because of a principle known as Lenz's law. There is an alternating current instead of a direct current within the bobbin because of the motion of the string and it moves towards and away from the pole piece of the pickup like the way the voltage of an alternating current increases or decreases. An acoustic guitar pickup is a small device inserted into the body of the guitar that allows an acoustic guitar to be plugged into an amplifier and this acoustic guitar pickup is easy to make and then used on any acoustic guitar. Open the buzzer element and extract the Piezo and the buzzer elements are made from two elements separated by crystals. It looks like a round, metal disk about the size of a can lid. Strip two inches off the end of the shielded cable. Solder one end onto the element. The ground wire needs to be soldered to the brass surface of the element. The positive wire needs to be soldered to the signal end of the element. Attach the audio jack to the element with the other end of the shielded wire. Solder the wires into place. Glue the small foam onto the back of the element. This improves the performance of the elements. Mark a hole on the side of the guitar close to the guitar strap knob for the audio jack. Drill a hole through the guitar at this mark. For best results, remove the guitar strings beforehand. Drill the hole with a steady smooth motion. If you drill too fast, the guitar may splinter.
