Description

A kind of plate membrane resonance leather recklessly

Technical field:

The utility model relates to Chinese national stringed instrument, particularly leather technical field recklessly.

Background technology:

Leather is the bass bowed instrument in the Chinese Musical Instruments recklessly.Hu Youyi horizontal cylinder shape of existing leather resonant, its left side cover and cover vibrating membrane, and the right side is a hollow out sound window, and other has a qin bar to be plugged among the resonant cylinder, have some strings to be fixed in qin bar upper end and resonant bottom.Below string, set up the support of qin sign indicating number to stand on the resonant barrel, qin sign indicating number bottom has the extension to enter in the resonant, which is provided with mesopore and be convenient to the part of qin bar in cylinder and pass, qin sign indicating number tail end is connected with the vibrating membrane inner face of resonant left side by a linkage structure.String vibration sound wave conducts to vibrating membrane by the linkage structure of qin sign indicating number tail end during performance.Existing as can be seen leather this indirect vibrational structure recklessly is difficult to make vibrating membrane fully to vibrate, and is less owing to the resonant specification again, the blocked up frequency that makes of barrel is higher, do not match with the pitch frequencies of string setting, so resonance state is not good, volume is also less.

Summary of the invention:

At the existing limitation of above-mentioned existing leather Hu, the utility model provides a kind of plate membrane resonance leather recklessly, its purpose is: change the structure of existing leather Chinese fiddle string to the indirect sound wave conduction of epithelium, and to make string directly make the vibrating membrane pressurized by the qin sign indicating number, produce direct sound wave conduction, and the adjustment by resonant specification and shape system, improve resonance state, vibrational state and tonequality volume.

Technical solutions of the utility model are:

Leather resonant recklessly is a casing, and a film drum hole is established at its panel middle part, corresponding a vibrating membrane drum that comprises vibrating membrane is installed, and the vibrating membrane inner face is provided with the cuticula plate, is provided with a sound column between the backboard of resonant and cuticula plate; Establish a fortune bow groove in the panel right side central of resonant; Leather qin bar recklessly is plugged in the resonant upper end; Some string one ends are fixed on qin bar top, and the other end is fixed on the resonant bottom; Between string and vibrating membrane, a qin sign indicating number is established in support.

The effect that the utility model scheme is embodied is:

Because qin sign indicating number directly support stands between string and the vibrating membrane, has guaranteed the abundant pressure of string to vibrating membrane, thereby make sound wave do the conduction of fullest to vibrating membrane, make that it produces directly, the vibration of fullest by the qin sign indicating number.Reduced frequency owing to enlarged resonant again, the pitch frequencies coupling that itself and string are set, and resonant is fully vibrated by the conduction of sound column, thereby vibrational state and resonance state are improved fully, again because vibrating membrane produces resonance among being arranged at panel, make tone color obtain new optimization simultaneously.

Description of drawings:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a left view of the present utility model.

The represented name of sequence number is called among above-mentioned each figure:

(1) resonant, (2) vibrating membrane drum, (2a) vibrating membrane, (2b) cuticula plate, (2c) drum circle, (2d) indent flanging, (3) groove, (4) sound column, (5) panel, (6) backboard, (7) qin bar, (8) string, (9) qin sign indicating number, (10) chord-drawing plate, (11) film drum hole.

Embodiment:

Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is specifically described:

Please referring to Fig. 1, Fig. 2.A kind of plate membrane resonance leather of the present utility model recklessly, its resonant 1 as a upright rectangular box body, the panel 5 of resonant 1 is established a quadrangular membrane drum hole 11 at the middle part of taking back, vibrating membrane drum 2 that comprises vibrating membrane 2a of corresponding installation, be provided with cuticula plate 2b at vibrating membrane 2a inner face, between the backboard 6 of resonant 1 and cuticula plate 2b, be provided with a sound column 4; Establish a fortune bow groove 3 in panel 5 right side central of resonant 1; There is a qin bar 7 to be plugged in resonant 1 upper end; Four string 8 one ends are fixed on qin bar 7 tops, and the other end is fixed on the bottom of resonant 1; And between string 8 and vibrating membrane 2a, a qin sign indicating number 9 has been established in support.

Again from Fig. 1 and Fig. 2 as can be seen, the vibrating membrane drum 2 in the utility model is that a drum circle 2c single face covers and covers vibrating membrane 2a, and drum circle 2c outside surface Lower Half external diameter is less than first half external diameter, thereby forms a circle indent flanging 2d; Its Lower Half is inserted the film drum hole 11 on the described panel 5, indent flanging 2d and the hole 11 peripheral driving fits of film drum.Simultaneously, be provided with cuticula plate 2b at the inner face of vibrating membrane 2a, its area is less than vibrating membrane 2a area, and is laminated with in the middle part of vibrating membrane 2a inner face.

From Fig. 1 and Fig. 2 as can be seen, resonant 1 of the present utility model is at the groove 3 of being convenient to transport bow of right side central setting, and its bottom is for connecting the inclined-plane of panel 5 and side, the right.In addition, it can also be seen that from figure that the lower end of four strings is fixed on and is positioned on the just basifacial chord-drawing plate 10 of resonant 1 in the utility model, chord-drawing plate 10 then is fixed in the bottom of resonant 1.

What need further specify is, sound column in the utility model and qin sign indicating number the position is set, can regulate according to the demand of acoustic quality.Simultaneously, the groove of resonant right side central can global design become hollow out sound window, also can leave the adjustment hole of being convenient to regulate sound column on the sound window.

In sum, the utility model has not only enlarged volume by the improvement of the aspects such as structure utilization, resonant specification and shape system of directly vibration, has also produced the effect and the good tone color thereof of plate membrane resonance, optimize sympathetic response and vibrational state, improved leather acoustic quality recklessly.
