Examples

The present embodiment provides a stringed tricine 10, which, as shown in fig. 1, includes a body 100, strings 200, a main bridge 300, a sub-bridge 400, and a headstock bridge 500.

As shown in fig. 1 and 2, the body 100 has a headstock 120 at one end and a cavity 110 at the other end. Compared with the traditional three-string, the three-string added string 10 adds three strings 200 in total, and the number of the strings 200 is six. The six strings 200 are grouped into three string groups 210, one for each two. The two strings 200 in each string set 210 are relatively close to each other, and when playing, the two strings 200 can be regarded as a whole to be subjected to playing, so that the two strings 200 are subjected to double-tone or accent resonance, not only can unique timbre be generated, but also the playing range is further widened.

In order to realize the novel playing mode, the three stringed strings 10 are modified correspondingly on the main supporting horse 300 as shown in fig. 3. The main bridge 300 is disposed on the surface of the cavity 110, and the main bridge 300 includes a first support member 310, a first conducting member 320, and a connecting member 330.

The first support 310 has a step shape and includes a relatively small upper surface 311, a relatively large lower surface, and a first inclined surface 312 and a second inclined surface 313 connecting the upper surface 311 and the lower surface. The first inclined surface 312 is provided with a first supporting groove group 3121, and the first supporting groove group 3121 includes a pair of first supporting grooves (not labeled) arranged side by side. The second inclined surface 313 is provided with a second support groove group 3131, and the second support groove group 3131 includes a pair of second support grooves (not labeled) arranged side by side. The upper surface 311 is provided with a third support groove group 3111, and the third support groove group 3111 includes a pair of third support grooves (not labeled) arranged side by side. The first, second, and third support grooves are all provided along the width direction of the first support member 310. The six strings 200 are engaged with the pair of first support grooves, the pair of second support grooves, and the pair of third support grooves, respectively. While the engagement is performed, grouping of the six strings 200 is also completed. Meanwhile, the traditional three-string 200 is in one plane, only two strings 200 can be used during playing, and the range of sound is narrow. However, in this embodiment, due to the unique shape of the first supporting member 310, the third supporting groove group 3111 is spaced apart from the cavity 110 by a greater distance than the first supporting groove group 3121 and the second supporting groove group 3131, and thus, the supporting grooves are distributed in a staggered manner. When the bow is used for playing, the bow hair can independently act on any one string set 210 without influencing other string sets 210, so as to achieve better playing effect.

Further, as shown in fig. 3, in the present embodiment, the included angles between the first inclined surface 312 and the upper surface 311 and the second inclined surface 313 are equal to each other, and are about 150 to 160 °. The first supporting groove, the second supporting groove and the third supporting groove are all arc-shaped grooves. The distance between the pair of first supporting grooves is 0.5-1 cm; the distance between the pair of second supporting grooves is 0.5-1 cm; the distance between the pair of third supporting grooves is 0.5-1 cm. Within the above distance range, the two strings 200 of the same string set 210 can better realize resonance, and the playing effect is better.

In addition, the first support 310 is further provided with a mass reduction hole 314, and the mass reduction hole 314 is located in the middle of the first support 310, is arranged along the width direction of the first support 310, and penetrates through the first support 310. The first supporting member 310 is further provided with a pair of conductive plus distance holes 315, the pair of conductive plus distance holes 315 are arranged at two sides of the mass reduction hole 314, and each conductive plus distance hole 315 is arranged along the width direction of the first supporting member 310 and penetrates through the first supporting member 310. The mass reducing holes 314 may serve to reduce the mass of the first support 310, making the first support 310 lighter and more susceptible to vibration. The distance of the vibration transmitted from the strings 200 to the cavity 110 can be extended by the transmission distance hole 315, so that the resonance effect is enhanced.

The first conducting member 320 is disposed along the length direction of the first supporting member 310, a pair of conducting portions 321 protruding from the bottom of the first conducting member 320 for connecting with the cavity 110, and the pair of conducting portions 321 are respectively disposed at two ends of the first conducting member 320 in the length direction. The two conductive parts 321 are connected to the cavity 110, so that two resonance points with the same frequency can be formed on the surface of the cavity 110 during playing, and the resonance effect is further enhanced.

The connection member 330 is positioned between the first support member 310 and the first guide member 320, and one end of the connection member 330 is connected to the lower surface of the first support member 310 and the other end is connected to the top of the first guide member 320. Wherein, the length of the first conducting member 320 is longer than that of the first supporting member 310, and the length of the connecting member 330 is shorter than that of the first conducting member 320, so as to form a structure similar to an I shape. The arrangement mode can also increase the conduction distance of vibration to achieve the effect of strengthening resonance.

Further, as shown in fig. 1 and 4, the three stringed strings 10 further include a secondary support bridge 400, and the secondary support bridge 400 is disposed on the surface of the cavity 110 on the side of the main support bridge 300 away from the headstock 120. In the conventional three-string instrument, when performing a playing performance, a bow (not shown) is erected on the side of the cavity 110 close to the head 120, and the strings 200 in the area are close to the body 100, so that the instrument is slightly compact for playing two strings 200. In the present embodiment, the player can play six strings 200 with a more apparent elbow. In order to increase the distance between the strings 200 and the body 100, it is preferable to move the main bridge 300 toward the headstock 120. However, if the main bridge 300 is moved toward the headstock 120, the strings 200 are easily attached to the cavities 110 at the end away from the headstock 120, thereby affecting the sounding of the stringed tri-strings 10. Based on this, the present embodiment adds the secondary support bridge 400 in addition to the main support bridge 300, and the secondary support bridge 400 can add a support point at the end far away from the headstock 120 to support the strings 200.

As shown in fig. 4, the sub support horse 400 includes a second support member 410 and a second conductive member 420, the second support member 410 is integrally formed in an isosceles triangle shape, and a third inclined surface 411 and a fourth inclined surface 412 are formed at the top of the second support member 410. The included angles between the third inclined surface 411 and the fourth inclined surface 412 and the surface of the piano cavity are equal and are 20-30 degrees. The third inclined plane 411 is provided with a fourth supporting groove 413 at an end far from the fourth inclined plane 412, the fourth inclined plane 412 is provided with a fifth supporting groove 414 at an end far from the third inclined plane 411, and a sixth supporting groove 415 is provided at a vertex where the third inclined plane 411 and the fourth inclined plane 412 meet. The fourth, fifth and sixth supporting

grooves

413, 414 and 415 penetrate the second supporter 410 in the width direction of the second supporter 410. The three string sets 210 are engaged with the fourth support groove 413, the fifth support groove 414 and the sixth support groove 415, respectively. It should be noted that, since the playing area of the three stringed instruments 10 is mainly concentrated on the side of the main support bridge 300 near the headstock 120, the sub-support bridge 400 only plays a supporting role, and for the convenience of processing, it is not necessary to provide a support slot for each string 200 independently, and it is sufficient to embed two strings 200 of each string set 210 in one support slot.

The second conductive element 420 is located below the second supporting element 410, the top of the second conductive element 420 is connected with the bottom of the second supporting element 410, and the bottom of the second conductive element 420 is provided with a main conductive surface 421; the second conductive member 420 has extension members 430 disposed at both ends in the length direction, the bottom of the extension member 430 is provided with a sub conductive surface 431, and the sub conductive surface 431 and the main conductive surface 421 are coplanar to form a conductive surface (not labeled) of the three stringed strings 10 for contacting with the musical instrument cavity 110. Preferably, the length of each of the sub conductive surfaces 431 is 1 to 1.3 times the length of the main conductive surface 421. When the three stringed instruments 10 are played, the vibrations of the strings 200 may be transmitted through the main bridge 300 and the sub bridge 400 at the same time, and the noise may be generated in the cavity 110, which may affect the playing effect. In order to avoid this, it is necessary to weaken the sub-horse 400 while enhancing the vibration transmission effect of the main horse 300. For this reason, the present embodiment designs the sub-horse 400 as a whole as a solid structure, and increases the contact area of the sub-horse 400 with the cavity 110 by the extension member 430 to achieve the weakening effect.

Meanwhile, the present embodiment further adds an absorbing buffer 440 to the secondary support horse 400, and the absorbing buffer 440 is disposed at the bottom of the second conductive element 420 and the extension element 430. The top of the absorbing bumper 440 is connected to the conductive surface. The width of the absorbing buffer member 440 is 1.5 to 2 times the width of the conducting surface, and the length of the absorbing buffer member 440 is 1.05 to 1.2 times the length of the conducting surface. The absorbing bumper 440 can further increase the contact area of the sub-mount bridge 400 with the cavity 110, and has an effect of absorbing vibration. Through the combined action of the extension member 430 and the absorbing and buffering member 440, the vibration transmitted to the piano cavity 110 by the secondary support bridge 400 is basically negligible, so that the interference to the playing effect can be avoided while the support function is played.

When the mounting is carried out, as shown in fig. 1 and 2, the main support bridge 300 is located at 1/4-1/3 lengths of the surface of the cavity 110 near one end of the headstock 120, and the sub-support bridge 400 is located at 1/4-1/3 lengths of the surface of the cavity 110 far from one end of the headstock 120. The mounting mode can increase the comfort of playing, and can also ensure the effective support of the string 200, so that the three stringed instrument 10 has more playing modes.

Further, as shown in fig. 5 and 6, the stringed tri-string instrument 10 further includes a headstock-supporting bridge 500, and the headstock-supporting bridge 500 is disposed on the headstock 120 at an end of the headstock 120 near the cavity 110. The head support bridge 500 is at one end of the head 120, and cooperates with the main support bridge 300 and the sub support bridge 400 to complete grouping and fixed support of the strings 200.

In this embodiment, the headstock support bridge 500 includes a body 510, the body 510 is generally strip-shaped, the body 510 is provided with three headstock support groove sets 520, and the three headstock support groove sets 520 are arranged at intervals along the length direction of the body 510; each headstock support groove group 520 comprises an A groove 521, a B groove 522 and a C groove 523, and the A groove 521, the B groove 522 and the C groove 523 are arranged along the width direction of the body 510 and penetrate through the body 510; in each headstock support groove group 520, the a groove 521 and the C groove 523 are located on both sides of the B groove 522, respectively, the a groove 521 and the B groove 522 penetrate the top of the body 510, and an a notch 5211 and a B notch 5221 are formed in the top of the body 510, respectively. A transition groove 524 is arranged between the B groove 522 and the C groove 523, and the transition groove 524 penetrates through groove walls of the B groove 522 and the C groove 523 to communicate the B groove 522 with the C groove 523. The three string groups 210 are respectively fitted with the three headstock 120 support grooves, and two strings 200 in each string group 210 are one inserted in the a groove 521 and the other inserted in the B groove 522 or the C groove 523. In mounting, the six strings 200 are fitted into the three a-slots 521 and the three B-slots 522 through the a-slots 5211 and the B-slots 5221, respectively. The width of the a, B and

C slots

521, 522, 523 is comparable to the diameter of the string 200, enabling better fixation of the string 200 when it is embedded therein. In addition, a plurality of anti-slip protrusions 525 are formed on the inner walls of the a, B and

C grooves

521, 522 and 523, the anti-slip protrusions 525 are formed along the width direction of the body 510, and the plurality of anti-slip protrusions 525 are formed at equal intervals. The friction of the groove wall to the strings 200 can be strengthened by the anti-slip convex ribs 525, and the fixing effect is improved.

In the present embodiment, as shown in fig. 6, the bottom of the B tank 522 is provided with a first opening 5222, the top of the C tank 523 is provided with a second opening 5231, and the transition tank 524 communicates the first opening 5222 and the second opening 5231. The B groove 522, the transition groove 524, and the C groove 523 form an "N" shaped structure when viewed from the side. When two strings 200 of the same group are located in the a-slot 521 and the B-slot 522, respectively, it is the distance most suitable for the two strings 200 to sound in resonance. However, when necessary, the strings 200 in the B-groove 522 can slide into the C-groove 523 through the transition groove 524, so that the distance between the two strings 200 is increased, thereby reducing the resonance sound production between the two strings 200, and even playing a single string 200 to generate a single tone, so that the three stringed instruments 10 with additional strings have richer playing modes. It should be noted that the "N" shaped structure is not the only structure of the present invention, and in other preferred embodiments of the present invention, the first opening 5222 and the second opening 5231 can be respectively disposed in the middle of the B groove 522 and the C groove 523 to form an "H" shaped structure, or other structures capable of playing a role of changing the groove. Similarly, according to actual needs, more installation grooves may be added on the side of the C groove 523 away from the B groove 522 to achieve more levels of distance adjustment, with reference to the arrangement manner of the C groove 523 and the transition groove 524.

To sum up, the embodiment of the present invention provides a three-string with string 10, which has six strings 200 compared with the traditional three-string. The six strings 200 are in a group, the two strings 200 in the same group are relatively close to each other, and can make double-tone or accent resonance when playing, and the resonance effect is further strengthened under the action of the main support horse 300, so that the unique timbre is shown. Meanwhile, different from the coplanar design of all the strings 200 in the traditional three-string instrument, the main support horse 300 has a height difference for supporting the three groups of strings 200, so that the traditional playing performance is more beneficial to playing performance, and the traditional three-string instrument has richer playing forms.
