Erhu bridge with adjustable volume

Abstract

The invention provides an Erhu bridge with adjustable volume, and the Erhu bridge comprises a pressing block which is provided with a pressing surface attached to an Erhu skin. The pressing block is provided with a string pillow which is provided with a string groove. The interior of the pressing block is provided with a slide cavity, and the interior of the slide cavity is cooperatively provided with a sliding plug. The center of the sliding plug is fixedly provided with a screw extending towards the string pillow. The screw rod is matched with an internal thread pipe. An end part of the internal thread pipe can be held by a hand outside the string pillow, and the internal thread pipe can rotate freely. Moreover, the internal thread pipe cannot move axially. A surface peripheral array, facing the pressing surface, of the sliding plug is provided with flexible convex blocks. The pressing surface of the pressing block is provided with through holes which are corresponding to the flexible convex blocks. When the sliding plug moves to a lower / upper limit position, the flexible convex blocks completely extend into or draw back into the through holes of the pressing surface. The Erhu bridge can randomly adjust the overall volume of an Erhu according to the needs, and flexibly meets various actual demands in a practice process.

Description

technical field [0001] The invention relates to the field of musical instruments, in particular to an erhu. Background technique [0002] In the traditional erhu, a bridge is attached to the skin of the qin tube, and the strings cross the bridge and press the bridge tightly on the skin, so that the vibration of the strings is transmitted to the skin through the bridge. When practicing the erhu, the sound is louder, which often causes disturbance to the residents in the apartment building; therefore, in order to reduce the volume of the erhu, a mute is generally used, which is made of metal parts and clamped on the bridge of the piano, which can greatly reduce the volume of the erhu. The volume of the erhu; however, due to the different situations of each person, the actual required volume reduction range is different. The traditional mute device is fixed for the volume reduction degree, which cannot fully meet the user's needs. Contents of the invention [0003] In view o...
