String instrument combined vibrating device

Abstract

The invention relates to a string instrument combined vibrating device, belonging to the field of instruments. The vibrating device comprises a mask 1, an inner membrane 2, a high frequency membrane 3, a sound column 4 and the like and is characterized in that the mask, the inner membrane and the high frequency membrane are connected into a whole by virtue of the sound column and are fixed at the front end of a lyre, and the inner membrane and the high frequency membrane are positioned in a lyre drum. The mask is made from a traditional material or artificial material, and loudspeaker diaphragms are utilized as the inner membrane and the high frequency membrane. When the lyre is played, a string vibrates to drive the mask to vibrate by virtue of a code and simultaneously drive the inner membrane and the high frequency membrane by virtue of the sound column to vibrate. By adopting the device, the volume can be increased, and the string instrument can acquire a balanced sound effect in a playing frequency range.

Description

1. Technical field [0001] The utility model discloses a combined vibrating device for a stringed musical instrument, which belongs to the field of musical instruments. 2. Background technology [0002] The diaphragm plays an important role in the sound production of stringed instruments. [0003] Taking the traditional erhu as an example, although precious python skin is used as the diaphragm, it generally has the following disadvantages: 1. The volume is too low. When the band plays together, even if it is equipped with more than a dozen erhus, it is still a disadvantaged group and is often used Other instruments drown out. 2. The high and low sounds are unbalanced, the volume is louder when playing with empty strings and the upper position, the lower the volume, the weaker the volume, and the lowest position can't even make a sound. [0004] The above problems are mainly related to the following reasons. [0005] (1) It is related to the effective chord length [0006]...

AI Technical Summary

Problems solved by technology

[0003]Taking the traditional erhu as an example, although precious python skin is used as the diaphragm, it generally has the following disadvantages: 1. The volume is too small. Paired with a dozen erhus, it's still an underdog, often overwhelmed by other instruments

2. Unbalanced high and low sounds, the volume is louder when playing with empty strings and the upper position, the lower the volume, the weaker the volume, and the lowest position can’t even make a sound
