Abstract
This utility model belongs to qin tool field, it is specifically related to a kind of automatic tone tuning device, including the battery being sequentially communicated, variator and CPU, a main switch it is provided with between battery and variator, this main switch is in order to control the power supply of whole device, variator and CPU are provided with an automatic tuning switch, and automatic tuning switch connects with CPU in order to control variator；The CPU that also includes being sequentially communicated, amplifier, motor, knob chord bolt, the information obtained from variator is carried out processing and exporting making motor work by amplifier by CPU, step motor drive knob, final drives string bolt to rotate.To realize stringed musical instrument automatic tuning, the student just starting stringed musical instrument is made to realize tuning.
Description
Technical field
This utility model belongs to qin tool field, is specifically related to a kind of automatic tone tuning device.
Background technology
Ordinary people just start learning instrument soon time (when of also accurately cannot distinguishing each scale), it is necessary to must be by variator or understand that the older generations of music help.Variator is the selection of most people, because understanding that the people of tuning will not always with you.In view of this, the applicant provides a kind of automatic tone tuning device, and this case thus produces.
Utility model content
The purpose of this utility model is to provide a kind of automatic tone tuning device, to realize stringed musical instrument automatic tuning, makes the student just starting stringed musical instrument realize tuning.
For achieving the above object, the specifically disclosed technical scheme of this utility model is: a kind of automatic tone tuning device, including the battery being sequentially communicated, variator and CPU, a main switch it is provided with between battery and variator, this main switch is in order to control the power supply of whole device, variator and CPU are provided with an automatic tuning switch, and automatic tuning switch connects with CPU in order to control variator；The CPU that also includes being sequentially communicated, amplifier, motor, knob chord bolt, the information obtained from variator is carried out processing and exporting making motor work by amplifier by CPU, step motor drive knob, final drives string bolt to rotate.
Further, described amplifier, motor, knob chord bolt have four groups, are communicated in described CPU.
Further, described CPU is also communicated with a buzzer, in order to remind user to tighten or to adjust pine string.
The beneficial effects of the utility model: the information obtained from variator is carried out processing and exporting making motor work by amplifier by this utility model by CPU, step motor drive knob, final drive string bolt rotates, and completes stringed musical instrument automatic tuning.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model application drawing.
Label declaration: 1 knob；2 motors；3 amplifiers；4 CPU；5 buzzers；6 string bolts；7 automatic tuning switches；8 variators；9 main switchs；10 batteries.
Detailed description of the invention
As shown in Figure 1, 2, what this utility model disclosed is a kind of automatic tone tuning device, including the battery 10 being sequentially communicated, variator 8 and CPU4, a main switch 9 it is provided with between battery 10 and variator 8, this main switch 9 is in order to control the power supply of whole device, being provided with an automatic tuning switch 7 between variator 8 and CPU4, automatic tuning switch 7 connects with CPU4 in order to control variator 8；The CPU4 that also includes being sequentially communicated, amplifier 3, motor 2, knob 1 chord bolt 6, the information obtained from variator 8 is carried out processing and exporting making motor 2 work by amplifier 3 by CPU4, motor 2 drive knob 1 rotates, and final drive string bolt 6 rotates；Described amplifier 3, motor 2, knob 1 chord bolt 6 have four groups, are communicated in described CPU4；A buzzer 5 also it is communicated with, in order to remind user to tighten or to adjust pine string on described CPU4.
Pressing main switch 9 and automatic tuning switch 7, the string of tuning once wanted by bullet.String sends vibrations, the frequency vibrated when sending different sounds due to different strings is different, according to these frequencies that shakes, variator 8 can judge what this sound is, thus this frequency and due frequency are compared, and then calculate this sound from should be to be transferred to sound differ.
The information input CPU4 that variator 8 will obtain, then output information to amplifier 3 through CPU4, make motor 2 work, drive knob 1 to rotate, finally make string bolt 6 rotate to reach the effect of automatic tuning.
If automatic tuning function is damaged, can close automatic tuning switch 7, open main switch 9 and switch to the original manual disc-jockey functionality of variator 8, buzzer 5 can remind user to tighten or adjust pine string, helps tuning acoustically.
