Abstract

The invention provides a flashing device of a guitar to solve the problem that the conventional guitar is difficult to grasp for a learner, and a teacher is difficult to show fingering of playing the guitar to the learner and difficult to know how the learner grasps the strings. The device comprises a signal amplification unit, a signal processing unit and a flashing unit, wherein the signal amplification unit is used for amplifying an input electric signal, and transmitting the electric signal to the signal processing unit; the signal processing unit is used for correspondingly outputting the amplified electric signal to a light emitting diode (LED) lamp in the flashing unit according to frequencies; and the flashing unit comprises five LED lamps, and is used for lighting the corresponding LED lamp according to the input electric signal. By the flashing device, after the electric signal output by the corresponding string is amplified, different LED lamps are activated according to different frequencies, so a learner can easily grasp the position of the string, meanwhile, and a teacher can teach the fingering of playing the guitar by an intuitive mode, and can grasp how the learner grasps the strings.

Description

technical field

[0001] The invention relates to a flashing device for a guitar. Background technique

[0002] The strings of existing guitars are relatively thin, and the distance between the strings is small, which is difficult for learners to grasp. Simultaneously, for teachers, it is difficult to show learners the fingering of playing the guitar and it is difficult to obtain The learner grasps the condition of the strings. Contents of the invention

[0003] The present invention aims to solve the problems that existing guitars are difficult for learners to grasp, and for teachers, it is also difficult to show learners the fingering of playing the guitar and to obtain the situation of learners mastering the strings, and provides a guitar The flash device includes: a signal amplification unit, which is used to amplify the input electrical signal and send it to the signal processing unit; a signal processing unit, which is used to output the amplified electrical signal...
