Abstract
The utility model discloses a demonstration ware is discerned to tone relates to music teaching aid field, and this demonstration ware is discerned to tone's pillar top is equipped with a plurality of sound production pieces, and the sound production piece is equipped with a plurality of bolt hole, and the sound production piece is fixed on the pillar through fastening bolt, and sound production piece and pillar and fastening bolt contact surface all be equipped with the flexible gasket of disc, and all sound production piece both sides are all fixed through two tight loops and are in the same place. The flexible gasket steadiness is good, can fix sound production piece steadily on the pillar, and the teacher can use and strike the hammer and strike a sound production piece sounding and let the student identify to through the panel number that changes the sound production piece, and a fastening bolt and a sound production upward different bolt hole cooperation, change the vocal length of stretching out, thereby change the vibration frequency and the intensity of vibration of sound production piece, send the sound of different tones and demonstrate for the student, let the student know the principle of pitch variation.
Description
Technical field
The utility model relates to Music teaching aid field, relates in particular to a kind of tone identification demonstration device.
Background technology
Tone represents the degree of the tune height of people's a sound of sense of hearing resolution. Tone is mainly determined by the frequency of sound, simultaneously also relevant with intensity of sound. To the pure tone of some strength, tone is lifting with the lifting of frequency.
Present music lesson also only rests on theoretical side for the teaching of tone, there is Music Teacher to use musical instrument to demonstrate different tones, for students identification, but musical instrument is difficult to react intuitively the relation of tonal variations and sounding body vibration frequency and intensity, be difficult to allow student have understanding intuitively to tone.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of tone identification demonstration device, use fastening bolt that some sounding sheets are fixed on important actor, coordinate with fastening bolt by bolt through-holes different on sounding sheet, and the quantity of sounding sheet on change important actor, thereby change vibration frequency and the oscillation intensity of sounding sheet, thereby show that intuitively tonal variations rule is to student.
For achieving the above object, the utility model provides following technical scheme: a kind of tone identification demonstration device, it is characterized in that: described tone identification demonstration device comprises striking to be hammered into shape and tubular important actor, important actor bottom is provided with tabular base, important actor top is provided with the sounding sheet of the rectangular plate shape that some chip sizes are identical, on all sounding sheets, same position is equipped with several bolt through-holes, sounding sheet is fixed on important actor by fastening bolt, fastening bolt is through bolt through-hole and the important actor threaded engagement of sounding sheet, and in the middle of sounding sheet and important actor and fastening bolt contact-making surface, be equipped with discoidal flexible gasket, all sounding sheets both sides are fixed together by two tight loops.
As the further optimization of the technical program, described important actor, strike hammer, base by cast iron manufacture, and important actor and base are monolithic construction.
As the further optimization of the technical program, described sounding sheet is manufactured by stainless steel, and the thickness of every sounding sheet is all not more than 1 ㎜.
As the further optimization of the technical program, described flexible gasket and tight loop are by rubber or silica gel material manufacture.
Adopt the beneficial effect of above technical scheme to be: the important actor top of this tone identification demonstration device is provided with some sounding sheets, sounding sheet is provided with several bolt through-holes, sounding sheet is fixed on important actor by fastening bolt, and sounding sheet and important actor and fastening bolt contact-making surface are equipped with discoidal flexible gasket, all sounding sheets both sides are all fixed together by two tight loops. Flexible gasket steadiness is good, sounding sheet stably can be fixed on important actor, teacher can use and strike hammer and knock sounding sheet and send the sound and allow student recognize, and by changing the sheet number of sounding sheet, and fastening bolt and different bolt through-holes cooperations on sounding sheet, change the length of stretching out of sounding sheet, thereby change vibration frequency and the oscillation intensity of sounding sheet, the sound that sends different tones shows student, allows student understand the principle of tonal variations.
Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the front view of a kind of tone identification of the utility model demonstration device;
Fig. 2 is the top view of a kind of tone identification of the utility model demonstration device.
Wherein, 1-important actor, 2-sounding sheet, 3-strike hammer, 4-base, 5-fastening bolt, 6-tight loop, 7-flexible gasket, 8-bolt through-hole.
Detailed description of the invention
Describe the preferred embodiment of a kind of tone identification of the utility model demonstration device in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 show the detailed description of the invention of a kind of tone identification of the utility model demonstration device: this tone identification demonstration device comprises and strikes hammer 3 and tubular important actor 1, important actor 1 bottom is provided with tabular base 4, and important actor 1 top is provided with the sounding sheet 2 of the rectangular plate shape that some chip sizes are identical.
As shown in Figure 2, on all sounding sheets 2, same position is equipped with several bolt through-holes 8, and the distance of adjacent two bolt through-holes 8 all equates, sounding sheet 2 is fixed on important actor 1 by fastening bolt 5, fastening bolt 5 is through the bolt through-hole 8 and important actor 1 threaded engagement of sounding sheet 2, and in the middle of sounding sheet 2 and important actor 1 and fastening bolt 5 contact-making surfaces, be equipped with discoidal flexible gasket 7, all sounding sheets 2 both sides are fixed together by two tight loops 6.
In conjunction with Fig. 1 and Fig. 2, important actor 1, strike hammer 3, base 4 is by cast iron manufacture, the shock-absorbing performance of cast iron is good, stability is strong, and hardness is large, and important actor 1 and base 4 are monolithic construction. Sounding sheet 2 is manufactured by stainless steel, and the thickness of every sounding sheet 2 is all not more than 1 ㎜, thinner thickness, and vibration frequency is high, and adjustable scope is large. Flexible gasket 7 and tight loop 6 are by rubber or silica gel material manufacture, and elasticated is good, and tight loop 6 can bundle sounding sheet 2 tightly.
Flexible gasket 7 steadiness are good, sounding sheet 2 stably can be fixed on important actor 1, teacher can use and strike hammer 3 and knock sounding sheet 2 and send the sound and allow student recognize, and by changing the sheet number of sounding sheet 2, and fastening bolt 5 coordinates from different bolt through-holes 8 on sounding sheet 2, change the length of stretching out of sounding sheet 2, thereby change vibration frequency and the oscillation intensity of sounding sheet 2, the sound that sends different tones shows student, allows student understand the principle of tonal variations.
Above is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
