MIDI files).When system works, by the musical instrument digital interface on MIDI source of sound plates, i.e. midi interface SD card can be called to drive
The corresponding MIDI files stored in dynamic plate.Because MIDI source of sound plate amplitude output signals are smaller, therefore need first blended amplification
Afterwards again through power amplification.
The system also includes power supply module (power supply), and power supply module is powered by RS485 buses to each sensing unit, simultaneously
Return host supplying power；Can external power supply directly power, or be powered using power module.
The distance of present invention sensing unit each in the design will be shortened, and it is single to optimize each sensing in installation process
The relative position of member, so as to allow player to be touched with hand without being trampled with pin, is easily and fast touched as far as possible
Each note is sent out, the characteristic of its electronic musical instrument is reduced to a greater extent, gives user more preferable music experience.
A kind of method for playing music based on tree-shaped stereochemical structure is also disclosed in embodiment：
When user's finger touched on the sensing unit of tree-shaped stereochemical structure or close to (effect is almost identical) when, sensing
The capacitance sensor of unit (i.e. signal input part) can receive caused by faint actuating signal capacitance variations and produce sensing letter
Number, meanwhile, pass to sub-processor after induced signal is amplified, according to the capacitance variations threshold decision being previously set whether someone
Touching is close, if judging to produce musical sound triggering command when having touching or close actuating signal, and musical sound triggering command is led to
The incoming bus control unit of RS485 buses is crossed, bus control unit recognizes the sensing unit of response by poll, by the volume of sensing unit
Code is transferred to the processor of host machine part, processor can future self-induction unit coding and decoding and by corresponding note information
MIDI source of sound plates are output to, the corresponding MIDI texts stored in SD card driving plate are called by the midi interface on MIDI source of sound plates
Part, then be successively amplified by Hybrid amplifier module and power amplifier (power amplifier), finally spread out of note from loudspeaker.
It is worth noting that, different sensing units (i.e. signal input part) can cause processor to adjust after receiving touch action
With different MIDI files, corresponding audio amplifier will also send different notes, and the signal continuously combined by difference is inputted just
Different music can be played.
By the method for playing music based on tree-shaped stereochemical structure, moved when user's both hands apply in different sensing units
When making signal, sound equipment just can send different happy symbols in succession.During concrete application, two kinds of moulds can be arranged as required into
Formula, that is, be set to that every time the fixed button of triggering plays corresponding fixed musical sound, or all played in order when triggering any button every time
The music score single-tone of selected melody, by the continuous touching or close of hand or hands, also can just reach " musical sound broadcasting " and " hand over
The effect of mutually performance ", so as to realize the effect of music.
Certainly, stereochemical structure disclosed in this invention is not limited in tree-shaped stereochemical structure as shown in Figure 4, completely can be with
According to scene demand, application demand etc., the 3-D solid structure of different expression form is designed to.
Although above embodiment of the present invention is described, the invention is not limited in above-mentioned specific embodiment party
Case and application field, above-mentioned specific embodiment are only schematical, guiding, rather than restricted.This area
Those of ordinary skill under the enlightenment of this specification, in the case where not departing from the scope that the claims in the present invention are protected,
The form of many kinds can also be made, these belong to the row of protection of the invention.
