Abstract
The utility model discloses a kind of upright piano with audio output function, comprise vertical piano body, also comprise one group of pressure transducer, this pressure transducer permutation and combination corresponding to each key is got up, and form one piece of pressure sensor plate, this pressure sensor plate is between hammer and string, be connected with qin body by runing rest, qin body bottom is provided with pedal, and pedal and runing rest link, and qin body side is provided with source of sound processor, digital socket, USB and source of sound processor power supply.The utility model by adding conversion equipment on the basis of original upright piano, make upright piano and the easy conversion of pianotron, by information processing and technology processing, make upright piano also can output audio signal, person easy to use regulates qin sound size, reduces interference to external world.
Description
Technical field
The utility model belongs to musical instrument field, is specifically related to a kind of upright piano with audio output function.
Background technology
In a prior art situation, upright piano and pianotron are separate classifications.Upright piano relies on traditional hammer to knock string sounding, and mellotron is by frequency division mimic channel sounding.In actual life, for piano practicer, the maximum drawback of pianotron compared by upright piano is that upright piano does not output on sound equipment or earphone by audio output apparatus, and to regulate sound of musical instrument volume, and pianotron has unique advantage in acoustic processing.
Summary of the invention
For making up the deficiencies in the prior art, the utility model adds conversion equipment on upright piano, makes upright piano be converted into pianotron, carries out audio frequency output.
The utility model is achieved by the following technical solution:
A kind of upright piano with audio output function, comprise vertical piano body, its special character is: also comprise one group of pressure transducer, this pressure transducer permutation and combination corresponding to each key is got up, form one piece of pressure sensor plate, this pressure sensor plate, between hammer and string, is connected with qin body by runing rest; Qin body bottom is provided with pedal, and pedal and runing rest link, and when pedal is stepped on to position B by position A, runing rest drive pressure sensor plate is gone to by position of floating and is parallel between hammer and string; Qin body side is provided with source of sound processor, digital socket, USB and source of sound processor power supply.
Upright piano of the present utility model and pianotron conversion equipment, key drives hammer to knock pressure transducer by hammered string instrument.
The beneficial effects of the utility model are: by technically adding conversion equipment at original upright piano, make upright piano and the easy conversion of pianotron, by processing information processing and technology, make upright piano also can output audio signal, to connect voice actuated device, person easy to use regulates qin sound size, particularly reduces interference to external world when practicing qin.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is external structure schematic diagram of the present utility model.
Accompanying drawing 2 is inner structure schematic diagram of the present utility model.
Accompanying drawing 3 is sectional views of the present utility model.
In figure, 1 pianotron pedal, 2 source of sound processors, 3 digital audio sockets, 4USB socket, 5 source of sound processor power supply, 6 runing rests, 7 pressure sensor plate, 8 hammers, 9 strings, 10 keys, 11 hammered string instruments, 12 position A, 13 position B.
Embodiment
Accompanying drawing is a kind of embodiment of the present utility model.This embodiment comprises vertical piano body, also comprise one group of pressure transducer, this pressure transducer gets up with the corresponding permutation and combination of each key 10, form one piece of pressure sensor plate 7, this pressure sensor plate 7, between hammer 8 and string 9, is connected with qin body by runing rest 6, and qin body bottom is provided with pedal 1, pedal 1 and runing rest 6 link, and qin body side is provided with source of sound processor 2, digital socket 3, USB 4 and source of sound processor power supply 5.
Push down on the pedal 1 fixing from position A12 to position B13 after, source of sound processor power supply 5 on ringing tone source processor 2 is energized work, now, upright piano is converted into pianotron pattern, under the interlock effect of pedal 1 and runing rest 6, runing rest 6 drives pressure sensor plate 7 to be gone to by floating position to be parallel between hammer 8 and string 9, simultaneously, under the effect of pianotron pedal 1, distance between hammered string instrument 11 and string 9 adds, the amount increased is the distance between pressure sensor plate 7 and string 9, under pianotron pattern, knocking key 10 drives hammer 8 to knock pressure sensor plate 13 by hammered string instrument 11, act on the power in pressure sensor plate 7, being transformed by pressure sensor plate 7 will output level, digital signal is converted into by through analog/digital conversion circuit, import source of sound processor 2 into, carry out acoustic processing again, synthesize corresponding key sound, loudspeaker is connected with USB 4 output by digital audio socket 3, the sound device such as sound equipment or earphone.The sound devices such as the wave volume opertaing device itself carried by source of sound processor 2 or the loudspeaker connected outward, sound equipment or earphone are regulated sound of musical instrument volume.
When wanting to be converted to upright piano pattern, pedal 1 being stepped on back from position B13 and is relaxed to position A12.Now, pressure sensor plate 7 is under the interlock effect of pedal 1 and runing rest 6, floating position is become from original being parallel between hammer 8 and string 9, simultaneously, hammered string instrument 11 turns back to origin-location under the effect of pianotron pedal 1, cut off source of sound processor power supply 5, sound processing apparatus quits work, and is now namely converted to upright piano completely.
