Abstract
A kind of LED keys instruction device, including：Lamp bar and controller; controller is connected with lamp bar by connecting line; lamp bar is flexible lamp strip; flexible lamp strip includes the flexible circuit board for being welded with LED light and driving the components such as IC; flexible circuit board bottom can be removably mounted on piano or electronic organ, the flexible imitative water transparent adhesive tape protection flexible circuit board of covering and be welded in component thereon at the top of flexible circuit board.As a result of flexible circuit board and the imitative water transparent adhesive tape of elasticity so that the LED key instruction devices of the application are foldable, curling, bending, when that need not use, it can be removed from piano or electronic organ, storage carries, and without causing circuit to damage, damages the key instruction function of lamp bar.
Description
Technical field
The present invention relates to piano study auxiliary device technical fields, and in particular to a kind of LED keys instruction device.
Background technology
For piano beginner, due to being unfamiliar with to key mapping, it is difficult to which continuity plays a first complete song, easily cause just
Scholar generates boredom, abandons piano practice.The hard of position instruction can be played by intelligent APP realizations by having on the market at present
Matter lamp bar, the hard lamp bar can be used as key indicator light, can excite the interest of learner, reduce study threshold.However, hard
The light bar of matter is not foldable, not easily contained and carrying, be easy to cause circuit damage once squeezing, the key for influencing hard lamp bar refers to
Show function.
Invention content
The application provides a kind of LED keys instruction device, which can be removably mounted on piano
Or on electronic organ, it is that piano beginner indicates key mapping as key indicator light, can also needing in use, from piano or electricity
It is removed on sub- qin, carries out folding storage without causing circuit to damage.
A kind of LED keys instruction device provided by the present application, including：Lamp bar and controller, controller and lamp bar pass through company
Wiring is connected, and the lamp bar is flexible lamp strip, and the flexible lamp strip includes the flexible circuit board for being welded with LED light and driving IC,
The flexible circuit board bottom can be removably mounted on piano or electronic organ, covering elasticity at the top of the flexible circuit board
Imitative water transparent adhesive tape.
In some embodiments, the flexible circuit board bottom is provided with 3M glue or several small magnet blocks.
In some embodiments, the controller includes being welded with control MCU, interfaces of connecting wires, USB interface and bluetooth module
Master board, the MIDI data that the controller can be received according to USB interface or bluetooth module controls the LED of lamp bar
Lamp on/off, the MIDI data are music score of Chinese operas information.
According to above-described embodiment, as a result of flexible circuit board and the imitative water transparent adhesive tape of elasticity so that the LED qins of the application
Key instruction device is foldable, curling, bending, do not needing in use, can be removed from piano or electronic organ, storing or carry,
Without causing circuit to damage, the key instruction function of lamp bar is damaged.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of LED keys instruction device.
Specific implementation mode
Below by specific implementation mode combination attached drawing, invention is further described in detail.Wherein different embodiments
Middle similar component uses associated similar element numbers.In the following embodiments, many datail descriptions be in order to
The application is better understood.However, those skilled in the art can be without lifting an eyebrow recognize, which part feature
It is dispensed, or can be substituted by other elements, material, method in varied situations.In some cases, this Shen
Please it is relevant some operation there is no in the description show or describe, this is the core in order to avoid the application by mistake
More descriptions are flooded, and to those skilled in the art, these relevant operations, which are described in detail, not to be necessary, they
It can completely understand relevant operation according to the general technology knowledge of description and this field in specification.
It is formed respectively in addition, feature described in this description, operation or feature can combine in any suitable way
Kind embodiment.
Referring to FIG. 1, being a kind of structural schematic diagram of LED keys instruction device, which includes：Lamp
Item 20 and controller 21, controller 21 and lamp bar 20 are connected by connecting line 6, and lamp bar 20 is flexible lamp strip, flexible lamp strip packet
The flexible circuit board 2 for being welded with LED light 3 and the flexible circuit board 2 of IC4 being driven to wait components is included, in some embodiments, flexible circuitry
2 bottom of plate is provided with 3M glue 1 or several small magnet blocks, and 2 bottom of flexible circuit board can be removably mounted on piano or electricity
On sub- qin, the top of flexible circuit board 2 covers flexible imitative water transparent adhesive tape and is used to protect flexible circuit board 2 and is welded in first device thereon
Part, wherein the imitative water transparent adhesive tape of elasticity can guarantee foldable flexible circuit board 2, curling, bending.
As a result of flexible circuit board and the imitative water transparent adhesive tape of elasticity so that the LED keys instruction device of the application can roll over
Folded, curling, bending are not needing in use, can be removed from piano or electronic organ, are storing or carry, without causing circuit
The key of damage, damage hard lamp bar indicates function.
In some embodiments, controller 21 includes being welded with control MCU10, interfaces of connecting wires 9, usb 11 and bluetooth
The master board 8 of module 12, wherein interfaces of connecting wires 9 is used to be connected to flexible lamp strip by connecting line 6.
Usb 11 or bluetooth module 12 receive the MIDI data that peripheral hardware terminal is sent, and control MCU10 receives MIDI data
Afterwards, the corresponding control signal of output, controls 3 light on and off of LED light of lamp bar 20, achievees the effect that aided education indicates, the MIDI numbers
According to for music score of Chinese operas information.
In one embodiment, in actual use, the LED key instruction devices of the application are laid on piano or electricity by user
On sub- qin, USB or bluetooth connection are carried out by terminal and controller 21, terminal will need the music score of Chinese operas played to be converted to MIDI data
And it is sent to controller 21, MIDI data is level signal by control MCU10, and the LED light 3 of control lamp bar 20 shines, reminds
User presses the key for needing to press.The terminal can be computer, mobile phone or tablet computer, and the LED keys of the application refer to
Showing device can be according to the study schedule and learning interest of user, and voluntarily the setting study music score of Chinese operas, improves learning interest and imitated with study
Rate.User can need not also use, and LED keys instruction device is removed from piano or electronic organ, after folding, storage
Or it carries.
Use above specific case is illustrated the present invention, is merely used to help understand the present invention, not limiting
The system present invention.For those skilled in the art, according to the thought of the present invention, can also make several simple
It deduces, deform or replaces.
