As shown in fig. 1 and 2, the konghou modulation sound transformer is mounted on the konghou and is used for modulating modulation sound, and the modulation sound transformer realizes quantitative modulation of modulation sound through an indexing positioning structure. The indexing positioning structure is a great improvement of the invention, and the traditional prior art can only regulate the distance between the poking head and the string by hand feel when regulating tuning, the accuracy of regulating tuning is completely dependent on the konghou user, and the tuning device cannot be quantitatively regulated without fixed quantization standard. The tuning regulator of the prior art can be regarded as a continuous variable, a user can select any value of the continuous variable in the regulating process, because unavoidable errors exist in manual operation, the any value is difficult to meet the accurate value of the tuning tone in a short time, the tuning tone is found to be inaccurate by stirring the stirring head 13 once, the tuning tone is possibly inaccurate by stirring the stirring head 13 once again, or although the tuning tone is more accurate than the tuning tone for the first time, the distance from the accurate value cannot be determined, the distance from the accurate value can be further adjusted by stirring the stirring head 13 once again, the repeated regulation consumes time, and the accuracy is difficult to achieve in a short time. The continuous change of the tuning sound regulator should be improved to discrete change, namely, the continuous variable for regulating the tuning sound in the traditional prior art is improved to discrete variable, so that a user can dial the dial head 13 to conduct tuning sound regulation, each time the regulation is at a certain value of the discrete variable, only the dial head 13 is needed to dial for several times to find a fixed discrete variable value, repeated attempts are not needed, and the advantage that the discrete variable is easy to regulate is that the continuous variable does not exist.

The indexing positioning structure is a mechanical structure, and comprises a rotating member capable of rotating by a self-axis and a supporting member which is contacted with the rotating member and can position the rotating member and rotate relative to the rotating member, wherein the rotating member rotates under the operation of a user, and the rotating member and the supporting member perform relative rotation, and meanwhile, the rotating period is discretized, so that the rotating member and the supporting member can uniformly stop at a plurality of positions in the process of relative rotation. The mechanical structure can be realized by gear meshing, multiple pin holes and splines, and the structure can realize indexing and positioning functions and realize accurate angle positioning of modulation and adjustment.

The konghou modulation tuning device shown in fig. 3 and 4 is installed on the konghou and is used for tuning modulation tuning, quantitative tuning of modulation tuning is achieved through an indexing positioning structure, the modulation tuning device comprises a modulation disc 6, a poking head 13 is installed on the modulation disc 6, an outer gear 11 is installed at the lower end portion of the modulation disc 6, a rotating shaft 9 is arranged below the modulation disc 6, an inner gear 10 is installed at the upper end portion of the rotating shaft 9, the inner gear 10 and the outer gear 11 are meshed with each other, and the modulation disc 6, the rotating shaft 9, the inner gear 10 and the outer gear 11 are connected together through screws 12 in a penetrating mode. During adjustment, the screw 12 is screwed out, the external gear is rotated, the external gear 11 and the internal gear 10 are re-meshed one by one, and the screw 12 is screwed. By adopting the tuning device, the initial position of the shifting head 13 can be adjusted by changing the relative meshing position of the external gear 11 and the internal gear 10, the angle of the tuning disc 6 is easy to position, a user does not need to enrich tuning experience, and accurate pitch can be adjusted by meshing the internal gear and the external gear in sequence and staggering the angle of one tooth each time. Moreover, after the tuning is aligned, the gear cannot be easily loosened and shifted, so that the tuning is more stable, and convenience is provided for a user.

In other embodiments, a multi-pin hole or spline structure is arranged between the inner gear 10 and the outer gear 11, and the like with indexing positioning function is replaced to realize accurate angular positioning of modulation and adjustment. The connection mode of the rotating disc 6 and the external gear 11 is key connection, pin connection, riveting, threaded connection or bonding, and the connection mode of the rotating shaft 9 and the internal gear 10 is key connection, pin connection, riveting, threaded connection, bonding and the like.

In another embodiment, the external gear 11 includes two layers of teeth in a stacked arrangement: a first layer of teeth 14 and a second layer of teeth 15, the first layer of teeth 14 meshing with the internal gear 10 and the second layer of teeth 15 meshing with the dial 6. The advantage of this embodiment is that: the angle of rotation is fixed as a result of each misalignment of the meshing crown gears with one tooth. In order for the tuning adjustment to be sufficiently precise, the crown gear must have sufficiently fine teeth. However, the size of the dial 6 itself is small, and if the teeth are too fine, the strength of the teeth will be insufficient to bear the reaction force of the pressed string, and the manufacturing cost of the gear will be greatly increased. For this purpose, a double-layer tooth structure is designed, which is characterized in that: the external gear 11 includes two layers of teeth, a first layer of teeth 14 meshing with the internal gear 10 and a second layer of teeth 15 meshing with the dial 6. The angle of each turn of the first layer of teeth 14 and the second layer of teeth 15 is different and not a multiple. The fine adjustment of the degree of the rotary dial can be realized through double-layer teeth. If the first layer of teeth is 24, every time one tooth rotates, 15 degrees are adopted, the second layer of teeth is 10, every time one tooth rotates, 36 degrees are adopted, if the first layer of teeth rotates clockwise by two teeth, the second layer of teeth rotates anticlockwise by one tooth, the rotating disc 6 rotates anticlockwise by 6 degrees as a whole, so that fine adjustment of the rotating disc 6 is realized, and the minimum angle which can be achieved by the angle adjustment of the rotating disc 6 is also realized.

In a further embodiment, the internal gear 10 is divided into two layers of teeth, the upper layer of teeth is meshed with the external gear 11, the lower layer of teeth is meshed with the rotating shaft 9, and the upper layer of teeth and the lower layer of teeth are meshed with the rotating shaft 6, so that fine adjustment of the angle of the rotating dial 6 is realized.

In other embodiments, the shifting head 13 is an adjustable shifting head, the adjustable shifting head is composed of a tubular tuning disc 16 and a threaded shifting head 17, the tubular tuning disc 16 is fixedly connected with the external gear 11, and the threaded shifting head 17 is in threaded connection with the tubular tuning disc 16. The advantage of this embodiment is that: the tuning adjustment is more accurate, the adjustable turning consists of a tubular tuning disc 16 and a thread turning head 17, the tubular tuning disc 16 and the external gear 11 are fixed together, and the thread turning head 17 is connected with the tubular tuning disc 16 through threads. The depth of the pressing string can be adjusted by adjusting the depth of the screw threads, and fine tuning of tuning can be realized. After the adjustment is completed, cement can be dripped into the threaded hole to permanently fasten the threaded hole. In the present embodiment, the thread of the thread pick 17 is a fine thread, and finer fine tuning is more accurate the finer the pitch. After the adjustment is completed, the screw thread shifting head 17 is permanently fastened by gluing, welding or riveting.

The above preferred embodiments are konghou-type tuning modulators, and when the konghou-type tuning modulators are mounted on konghou musical instruments, other embodiments can be formed, and these embodiments can be combined with each other to form other embodiments. It will be apparent to those skilled in the art that various other embodiments of the invention can be made in accordance with the invention without departing from the spirit and substance of the invention, and that these modifications and variations are intended to be within the scope of the appended claims.
