Abstract
An electronic sound-transmitting device used for an erhu is composed of a piezoelectric ceramic sheet, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a first capacitor, a second capacitor, a third capacitor, a transistor and a three-core socket. Compared with the prior art, the electronic sound-transmitting device of the utility model has the advantages of simple structure, convenient use and low cost. With the movement range of a performer being not affected, the electronic sound-transmitting device can transmit the sound of the erhu to a sound amplification device in a high-fidelity manner, and satisfy the requirement that more audiences and audiences at farther positions can enjoy the performance of the erhu.
Description
Technical field
The utility model relates to a kind of electronics sound-conducting apparatus, is specifically related to a kind of urheen electronics sound-conducting apparatus.
Background technology
The volume that Chinese nation's musical instrument sends is all more small and weak, and particularly urheen only can be propagated the distance about ten meters, appreciates for the audience nearby who surrounds and watches, and can not satisfy how farther audience and in time hear the demand that plays folk music.At present, all adopt the electronics mode of amplifying to come this deficiency of quasi-complement in the concert occasion, but urheen be difficult to cause distortion near microphone, had a strong impact on tone color and normally exported, make performing effect inferior.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of urheen electronics sound-conducting apparatus is provided.
Its technical scheme is: be made up of piezoelectric ceramic piece, first resistance, second resistance, the 3rd resistance, the 4th resistance, the 5th resistance, first electric capacity, second electric capacity, the 3rd electric capacity, triode and three core sockets; One end of described piezoelectric ceramic piece is connected with the negative pole of first electric capacity, the positive pole of first electric capacity is connected with the g utmost point of triode and an end of the 3rd resistance, the other end of the 3rd resistance is connected with an end of first resistance and an end of second resistance, the other end of first resistance is connected with an end of the 4th resistance and 2 ends of three core sockets, the other end of the 4th resistance is connected with the positive pole of the 3rd electric capacity and the d utmost point of triode, the negative pole of the 3rd electric capacity is connected with 1 end of three core sockets, and the s utmost point of triode is connected with an end anodal and the 5th resistance of second electric capacity; The other end of described electroceramics sheet is connected with the other end of second resistance, the other end of the 5th resistance, the negative pole of second electric capacity and 3 ends of three core sockets.
Wherein, described triode is fet, and its model is 3DJ6.The diameter of described electroceramics sheet is less than 27 millimeters.
The utility model has advantage simple in structure, easy to use, with low cost compared with prior art.And can also be under the situation that does not influence performer's scope of activities, the public address equipment that is sent to urheen sound high-fidelity has satisfied the demand that how farther audience in time hears Erhu playing.
