AI Technical Summary
Technical Problem
Traditional erhus suffer from a lack of richness and fullness in sound quality due to differences in materials, especially noticeable in low- to mid-range erhus.
Method used
By installing connectors and tone window adjusters on the erhu soundbox, the length of the air column and the size of the tone window can be adjusted, thereby changing the gap between the inner leaf and the tone window, thus improving the sound quality and effect.
Benefits of technology
Without changing the materials of the core components, the sound quality and effects are improved through the regulator, especially significantly enhancing the tone of mid-to-low-end erhus. It is inexpensive and easy to operate.

Abstract
This utility model discloses an erhu soundbox resonance adjuster, including a connector mounted on the erhu soundbox. An auxiliary adjusting cylinder is mounted on the connector, and the auxiliary adjusting cylinder is internally threaded with a tone window adjuster for changing the length of the air column in the erhu soundbox. The tone window adjuster includes an outer leaf and an inner leaf that rotates on the outer leaf. The outer leaf has tone window holes of a shape, size, and number adapted to the inner leaf. When the inner leaf rotates on the outer leaf, it changes the size of the gap between the inner leaf and the tone window holes, thereby transmitting different levels of sound quality and effect. This utility model improves and enhances the sound quality and effect of the erhu by adding an erhu soundbox resonance adjuster and appropriately adjusting the length of the air column in the erhu soundbox and the size of the tone window holes. Especially for mid-to-low-end erhus, this invention allows for a significant improvement in sound quality and effect through low cost and simple operation, contributing to the promotion of traditional folk musical instruments.
