Exploration and Design of Folk Guitar Stereo Pickup
An ultra-thin and easy to install stereo pickup is designed to improve the artistic expression of folk guitar in recording and performance.The control variable of an electromagnet plucking system is designed,and the best scheme to improve the signal-to-noise ratio is found by comparing two kinds of electromagnetic coil structure schemes.The experimental results show that the first end of the two electromagnetic coil sensors is connected in series with the first section in the same winding direction,and the opposite direction of the magnetic poles of the two magnets can increase the effective signal quantity picked up.Similarly,the head end of the two electromagnetic coil sensors is connected in series with the tail end in the opposite winding direction,and the magnetic pole direction is opposite.The ideas presented lay the foundation for the design of guitar pickup.
