Tuning device

Abstract

The invention relates to a tuning device comprising a vibration sensor, a signal processing module, and an LED lamp assembly. The vibration sensor arranged inside a sound box of a musical instrument is used for acquiring an acoustical signal and converting the acoustical signal into a signal source. The signal processing module connected with the vibration sensor is used for carrying out A / D conversion on a signal source to obtain a predetermined signal. The LED lamp assembly is connected with the signal processing module and comprises a plurality of LED lamps corresponding to capo positions of the musical instrument and a fixed plate for installing the LED lamps, wherein the fixed plate is arranged at a fingerboard side of the musical instrument. The tuning device has the excellent effects that: the LED lamp assembly is arranged on the fingerboard side of surface of the musical instrument, and the fingerboard and the LED lamp assembly are arranged at the same position, so that a problem that the eye contact of the player needs to be switched between the fingerboard and the tuning device back and forth when the player is playing the musical instrument in the prior art can be solved, and thus the fatigue caused by frequent focus switching of eyes can be avoided. Meanwhile, the signal identification time is shortened; and with the on-off way of the LED lamps, the user can obtain correctness information of the playing intonation rapidly.

Description

technical field [0001] The invention relates to the technical field of musical instruments, in particular to a tuner. Background technique [0002] In the process of music learning, the pitch of the musical instrument is very important. If the pitch of the musical instrument is not accurate, it will affect the learner's judgment of the pitch and affect the hearing, and it will affect the performance effect and destroy the sense of music. Therefore, before playing the musical instrument , the user needs to use a tuner to tune the instrument. The structure of existing tuner is made up of vibration sensor, single-chip microcomputer and display screen, and its principle is that vibration sensor collects the frequency of sound, and sends to single-chip microcomputer to process, and single-chip computer calculates the sound name of corresponding pitch, uses sound name The seven English letters A-G are displayed on the screen. Its disadvantages are as follows: First, because the ...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: First, because the pitch of the musical instrument is controlled by the position of the finger, and only English letters can be displayed on the screen, the user needs to think and react from reading the letter to adjusting the finger position, and it will not respond when playing quickly First, it is not suitable for tuning when playing; the second is that the ordinary tuner is set on the headstock, the fingerboard and the tuner are not in the same position, and the user needs to switch back and forth between the fingerboard and the tuner when playing. The operation is inconvenient, and the user cannot take care of both

Although the tuner can realize the recording function, its structure is complicated and the operation is inconvenient. It also cannot solve the problem of the existing tuner switching back and forth between the fingerboard and the tuner body, and the practicability is poor.
