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
The present invention relates to a kind of flasher of guitar.
Background technology
The string of existing guitar is thinner, and the distance between the string is less, difficult assurance for the learner simultaneously for the instructor, also exists to be difficult to show the fingering of playing guitar and be difficult to obtain the problem that the learner grasps the situation of string to the learner.
Summary of the invention
The present invention is for solving difficult assurance for the learner that existing guitar exists, also exist for the instructor and to be difficult to show the fingering play guitar and be difficult to obtain the problem that the learner grasps the situation of string to the learner, a kind of flasher of guitar is provided, and this device comprises:
Signal amplification unit is used for sending to signal processing unit after the electric signal amplification with input;
Signal processing unit, the electric signal after being used for amplifying output to the LED lamp of flashing light unit by the frequency correspondence;
Flashing light unit comprises five LED lamps, is used for lighting corresponding LED lamp according to the electric signal of input.
The present invention amplifies the back by the electric signal with corresponding string output and activates different LED lamps according to different frequencies, make the position that the learner can easier grasp string, the fingering that also can play guitar with mode professor intuitively of instructor simultaneously, and can grasp the situation that the learner grasps string.
Description of drawings
Fig. 1 is the structural representation of the flasher of guitar.
Embodiment
The specific embodiment of the present invention provides a kind of flasher of guitar, as shown in Figure 1, this device comprises signal amplification unit 1, signal processing unit 2, flashing light unit 3 and power supply unit 4, sends to signal processing unit 2 after the electric signal that signal amplification unit 1 is used for importing amplifies; Electric signal after signal processing unit 2 is used for amplifying outputs to the LED lamp of flashing light unit 3 by the frequency correspondence; Flashing light unit 3 comprises five LED lamps, is used for lighting corresponding LED lamp according to the electric signal of input; Power supply unit 4 is used to signal amplification unit 1 and flashing light unit 3 power supplies.
