Description
Technical field
The utility model belongs to piano pestle technical field of angle detection, and in particular to a kind of piano tuning, parts adjustment work
Tool hammerhead angle measurement equipment.
Background technology
Modern piano, is described as the king of musical instrument in musical instrument.Its broad range is across 7 octaves (A2-c5), and its is only
Which part musical instrument some performances, aesthetic value and abundant expressive force, do not have can be by comparison.Modern piano can reflect that works are most weak
Change to most strong dynamics, embody multi-level acoustic characteristic, its abundant expressive force can simulate whole large-scale symphony
Team, being processed by playing skill can make music expression more diversification, or even connect various interrupted tones, continuant etc. can be sharp
And optionally show, can truly give expression to rich colors and artistic conception that melody is taken out of.
When player's piano, by finger tip contacts key, drive keyboard hammered string instrument system accurately and quickly several
Level lever transmission, draws hammerhead and taps string, string is produced vibration, and vibrational energy has been passed into sympathetic response work by string code
Soundboard, the vibration of soundboard produces the ripple of density in atmosphere, sends the sound of the piano that we are heard.
The good tonequality 50% of piano is decided by source of sound, and 25% is hammerhead.Certainly, these are weighed with any data
The primary and secondary of factor is difficult.But certainly, hammerhead is a critically important factor for influenceing piano sound, with string row and sound
Plate together decides on the tonequality of piano.The quality of hammerhead, elasticity, hit string mode and hit the length that string lasts and be to determine piano sound
Key.
At present, in the market can detect hammerhead angle without preferably detection instrument, in this case piano hammerhead angle
It is difficult to ensure that the hitting dynamics with grasp hammerhead.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of piano tuning, parts adjustment
Instrument hammerhead angle measurement equipment.
A kind of piano tuning, parts adjustment instrument hammerhead angle measurement equipment, including measurement bay, base, measuring bolt, it is special
Levy and be：The end of the measuring bolt is tip-angled shape, and measurement bay is provided with 2 ~ 4 screwed holes for vertically arranging, and is surveyed
2 groups of measuring bolts are installed in the screwed hole for measuring frame, 2 groups of measuring bolt length are identical, measurement bay is fixedly arranged in the middle of semicircle
Angle dial, the circular place of angle dial semicircle is provided with gravity pointer, the sensing of gravity pointer vertically downward, measurement
Frame is fixed on the sidepiece of extension frame by rotating shaft, and the end of rotating shaft is provided with rotary damper, and extension frame is fixed by screws in
The groove of rectangle is provided with base, in the middle part of base, horizon rule is provided with the rectangular recess of base.
Preferably, the bottom at four angles of the base is provided with adjustment knob.
Compared with prior art, the beneficial effects of the utility model：
The utility model when in use, is first adjusted to horizontality base, and wheel measuring frame makes two groups of measuring bolts
End wedge angle aligns with hammerhead end face, and reading of the gravity pointer on angle dial is the angle of inclination of hammerhead end face；It is logical
Cross setting rotary damper and cause that measurement bay rotates steadily, and arbitrary angle can be rested on, user-friendly, this reality
Have the advantages that simple structure, easy to use, certainty of measurement are high with new.
Brief description of the drawings
Fig. 1 is a kind of piano tuning of the utility model, the structural representation of parts adjustment instrument hammerhead angle measurement equipment.
In figure, 1, measurement bay, 2, measuring bolt, 3, gravity pointer, 4, angle dial, 5, hammerhead, 6, rotary damper,
7th, frame is extended, 8, base, 9, horizon rule, 10, adjustment knob.
Specific embodiment
Referring to Fig. 1, a kind of piano tuning, parts adjustment instrument hammerhead angle measurement equipment, including measurement bay 1, base 8, survey
Amount screw 2, it is characterised in that：The end of the measuring bolt 2 is tip-angled shape, and measurement bay 1 is provided with 2 ~ 4 and vertically arranges
The screwed hole of row, it is identical to be provided with 2 groups of measuring bolts, 2,2 groups of length of measuring bolt 2 in the screwed hole of measurement bay 1, measurement bay 1
Semicircular angle dial 4 is fixedly arranged in the middle of, the circular place of the semicircle of angle dial 4 is provided with gravity pointer 3, gravity pointer
Vertically downward, measurement bay 1 is fixed on the sidepiece of extension frame 7 by rotating shaft, and the end of rotating shaft is provided with rotary damper for 3 sensing
6, extension frame 7 is fixed by screws on base 8, and the middle part of base 8 is provided with the groove of rectangle, is set in the rectangular recess of base 8
There is horizon rule 9.
The bottom at four angles of the base 8 is provided with adjustment knob 10.
Technical solutions of the utility model are exemplarily described above in conjunction with accompanying drawing to utility model, it is clear that this practicality
New implementing is not subject to the restrictions described above, as long as employ method design of the present utility model and technical scheme carrying out
Various unsubstantialities improve, or it is not improved the design of utility model and technical scheme are directly applied into other occasions,
Within protection domain of the present utility model.
