Description

Trill urheen

Technical field

The present invention relates to musical instrument field, especially, it is related to a kind of urheen.

Background technology

During Erhu playing, in order to realize tremolo effect, vibrato skill is generally used；, can only for vibrato skill Realize the relatively low trill of frequency that trembles；And gradually enriching with contemporary music, the performance song of urheen is from traditional music Rock music field is extended to, in the case, needs to form the high speed trill close to electric distortion tone color often, this is for passing For system urheen, it is clear that helpless.

The content of the invention

In view of the above-mentioned problems, it is an object of the invention to provide a kind of trill urheen, the trill urheen can played Cheng Zhong, conveniently realizes high speed tremolo effect.

The technical solution adopted for the present invention to solve the technical problems is：The trill urheen include scroll head, rod, barrel, Bow；The scroll head provided with two around string axle, it is described in string axle rotating around being equipped with a string, two strings Mutually abut and extend downward into the barrel bottom；The top of the rod is provided with a thousand pieces of gold mechanism, a thousand pieces of gold mechanism Pedestal including being fixed on rod, and the pressure string part of string is inwardly compressed, pass through pressure between the pedestal and pressure string part Electroceramics block is connected, and power module of the piezoelectric ceramics block in the pedestal is powered, and horizontal during piezoelectric ceramics block work To vibration.

Preferably, the pressure string part, which includes one, surrounds the string, and the not enclosure with string contact, and From being screwed into laterally outside for enclosure it is on the inside of enclosure, while towards string, the adjusting screw rod of rod；The adjusting screw rod The inner props up the string.

Preferably, the power module has the chargeable battery in the pedestal to power.

Preferably, having on-off switch between the power module and the piezoelectric ceramics block, the on-off switch is Push switch located at the barrel bottom；Because barrel generally rests on leg, therefore, when needing to play trill, only need The on-off switch is pressed, it is closed, and during without trill, then the on-off switch is pressed once again, it is disconnected, so as to In the flexible modulation voice effect in playing procedure.

Preferably, an input of the output end of the power module directly with the piezoelectric ceramics block is electrical Connection, another output end is electrically connected at the rod that outer surface is made up of metal level；The bowstring of the string and bow In mixed with conductive fiber, another input of the piezoelectric ceramics block is electrically connected with the string；Thus, when needing performance to quiver During sound, only the bowstring of bow need to be made to rub rod, then the piezoelectric ceramics block is switched on, so that continuous shaking；When without trill When, then bowstring is deviateed rod, you can piezoelectric ceramics block is stopped vibration；Thus, audio extremely can easily be switched.

The beneficial effects of the present invention are：The trill urheen need to such as produce high speed tremolo effect in playing procedure, then only The piezoelectric ceramics block need to be connected, then piezoelectric ceramics block drives the pressure string part continuous transverse vibration so that string it is elastic Continuous shaking, so as to produce high speed tremolo effect.

Brief description of the drawings

Fig. 1 is the schematic diagram of embodiment one of this trill urheen.

During Fig. 2 is the embodiment one of this trill urheen, the axial schematic diagram of a thousand pieces of gold mechanism.

Fig. 3 is the schematic diagram of embodiment two of this trill urheen.

Embodiment

The present invention is further described with reference to the accompanying drawings and examples：

Embodiment one：

In the embodiment one shown in Fig. 1, Fig. 2, the trill urheen includes scroll head 11, rod 12, barrel 13, bow（Do not scheme Show）；The scroll head 11 provided with two around string axle 14, it is described in string axle 14 rotating around being equipped with a string 2, two institutes State string mutually to abut and extend downward into the bottom of barrel 13, and push down the bridge 15 of the end of barrel 13.

The top of the rod 12 is provided with a thousand pieces of gold mechanism, and a thousand pieces of gold mechanism is as shown in Fig. 2 including being fixed on rod 12 pedestal 31, and the pressure string part 32 of string is inwardly compressed, made pottery between the pedestal 31 and pressure string part 32 by piezoelectricity Porcelain block 33 is connected；The pressure string part 32 includes one and surrounds the string, and the not enclosure 321 with string contact, and From enclosure 321 be screwed into laterally outside the inner side of enclosure 321, while towards string 2, the adjusting screw rod 322 of rod 12；Institute The inner for stating adjusting screw rod 322 props up the string 2, thus, and adjusting screw rod 322 is twisted by choosing, you can compress the string 2.

Power module of the piezoelectric ceramics block 33 in the pedestal 31 is powered, and horizontal during the piezoelectric ceramics block 33 work To vibration.

Above-mentioned trill urheen, the power module has the chargeable battery in the pedestal 31 to power.

In the present embodiment one, there is on-off switch 4, the break-make between the power module and the piezoelectric ceramics block 33 Switch 4 is the push switch located at the bottom of barrel 13；Because barrel 13 generally rests on leg, therefore, needing to play During trill, the on-off switch 4 need to only be pressed, close it, and during without trill, then the on-off switch 4 pressed once again, Disconnect it, in order to the flexible modulation voice effect in playing procedure.

Above-mentioned trill urheen need to such as produce high speed tremolo effect in playing procedure, then need to only connect the piezoelectric ceramics Block 33, then piezoelectric ceramics block 33 drive the continuous transverse vibration of pressure string part 32 so that the elastic continuous shaking of string 2, from And produce high speed tremolo effect.

Embodiment two：

For the embodiment three shown in Fig. 3, the difference of itself and embodiment one is：There is no the on-off switch 4；And in reality Apply in example two, an output end of the power module is directly electrically connected with an input of the piezoelectric ceramics block 33, Another output end is electrically connected at the rod 12 that outer surface is made up of metal level；In the bowstring of the string 2 and bow Mixed with conductive fiber, another input of the piezoelectric ceramics block 33 is electrically connected with the string 2；Thus, when need play During trill, only the bowstring of bow need to be made to rub rod 12, then the piezoelectric ceramics block 33 is switched on, so that continuous shaking；Work as nothing When needing trill, then bowstring is set to deviate rod 12, you can piezoelectric ceramics block 33 is stopped vibration；Compared to embodiment one, embodiment Two can more easily switch audio, it is possible to preferably keep the continuity played.

The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification for being made, equivalent substitution should be included in the scope of the protection.
