Description

Urheen megaphone

Technical Field

The utility model is applied to the field of music performance, relates to a urheen of a folk musical instrument, and particularly relates to a device for amplifying or reducing sound, which changes the volume of the urheen.

Background

Urheen is a traditional musical instrument in China, and is widely spread among people, and urheen accompaniment is required for various dramas. The volume of the urheen is generated by resonance sound of strings and leather films, and the volume of the urheen is generated by a window after being amplified by a musical instrument cylinder. Therefore, the cost of the two-stringed bowed instrument is low, and the main reason is that the materials and the working of strings, films and musical instrument barrels directly influence the tone quality and the volume of the two-stringed instrument. In particular, the shape of the barrels directly determines the propagation of the air vibration, which is directly related to the flying sounds, and most of the barrels are in a regular hexagonal shape, and a few of the barrels are in a regular octagonal shape or a round shape. The volume of the two-stringed bowed instrument is smaller than that of the performance hall, and special pickup and sound amplifying equipment are needed when the two-stringed instrument is used for playing the two-stringed instrument, but the volume of the two-stringed instrument is enough to disturb the rest of neighbors when the two-stringed instrument is used for playing the two-stringed instrument.

In order to increase the volume of the urheen, various patents provide different schemes, for example, CN202339699U discloses a urheen with an octagonal section, the horn shape of the urheen is utilized to increase the sound amplifying effect, the sound amplifying effect is limited, and the volume is insufficient to meet the requirement of a performance hall.

Detailed Description

Example 1

The structure of the sound amplifying device in this embodiment is shown in fig. 1-4, in fig. 1, the lower end of the two-stringed bowed instrument stem 1 is connected with the instrument tube 3, one end of the instrument tube 3 is wrapped with the leather membrane 2, and the leather membrane 2 and the strings are resonated and sounded. The other end of the musical instrument barrel 3 is a musical instrument window 5, and a window hole is formed in the musical instrument window 5, so that musical instrument sound emission is facilitated. At the bottom of a musical instrument barrel, a musical instrument support 4 is fixedly connected, and the musical instrument support 4 is placed on the legs during sitting posture performance. The sound amplifying device of the embodiment is sleeved at the window end of the musical instrument barrel and comprises a cover barrel 7, a horn barrel 8, a sound amplifier 9 and the like, wherein the cover barrel 7 is in a hexagonal shape, as shown in fig. 4, one end section of the cover barrel is hexagonal, and the cover barrel is used for being inserted into and connected with the musical instrument barrel, as shown in fig. 2. One end is a cylinder with a cross section, and a connecting horn 8 is inserted into the cylinder, as shown in figure 1. The horn cylinder 8 is inserted into the cylinder end of the cover cylinder 7 and is fixed by virtue of friction force, the horn cylinder 8 can rotate around the cylinder end, so that the horn direction can be adjusted, the amplified sound is directionally transmitted, the sound of the urheen performance is further transmitted after being amplified, and the device is suitable for a spacious performance hall environment.

A flexible pad 10 is fixed on the hexagonal inner wall of the cylinder end of the cover cylinder, and the flexible pad 10 can be made of flexible materials such as rubber, sponge, cloth materials and the like. The friction force between the cover cylinder 7 and the organ cylinder 3 can be increased, and the cover cylinder is fixed at the end part of the organ window of the organ cylinder 3 by using the friction force; secondly, the material is soft, and the external paint surface of the musical instrument barrel cannot be damaged. The loudspeaker 9 is fixedly arranged in the middle of the inner cavity of the cover cylinder 7 by a screw 11. The loudspeaker is the prior art, is just different with the loudspeaker shape of selling on the market, is hexagonal, conveniently fixes inside the cover section of thick bamboo. The loudspeaker meets the requirement of music amplification, and does not change the tone quality on the basis of power amplification. At the bottom of the loudspeaker, a battery 6 is arranged, and the battery 6 is a rechargeable battery and can provide electric energy for the loudspeaker 9.

When the two-stringed bowed instrument is used, the instrument barrel end of the cover barrel is sleeved into the instrument window end of the instrument barrel to be fixed, the horn barrel 8 is inserted, the direction is adjusted in a rotating mode, and the battery switch is turned on to play the two-stringed bowed instrument. After playing, the battery is closed, the cover cylinder 7 and the horn cylinder 8 are pulled out, and the musical instrument box is placed in the musical instrument box, so that the musical instrument is convenient and quick to install and detach.
