Abstract

本实用新型是属于民族拉弦乐器弦微调器,其特征是装于弦轴端部,利用螺钉调节琴弦局部张力,达到迅速、轻便调好空弦音准。本实用新型结构简单,安装方便,制造成本低,易于推广使用。

Description

二胡类拉弦乐器弦轴微调器
本实用新型属于民族拉弦乐器琴弦微调音高之用。
民族拉弦乐器的琴弦是一端固定在弦轴上,另一固定在琴筒下方,中间穿过“千斤”,“千斤”至琴码为有效振动弦长,通过琴码传递振动于皮膜而发出乐音。琴弦拉紧程度就是决定空弦音高准确与否?而琴弦紧张度是靠弦轴与琴杆之间磨擦来固定的。转动弦轴可调整空弦音准,但转动时需一边转,一边推紧,以免松开,要让两条弦调到准确音高较费事,要么转多了,要么又退过头,往往需多次反复调试才能调准。即使空弦调准了,由于气候影响及按指压力等因素,音准亦会发生微小变化,又要重新调试。为解决定弦准确便捷,曾采用多种方法,均不甚理想。
本实用新型的目的是对基本已接近音准的琴弦,利用装于弦轴端部的微调器,微调弦轴切点到弦勾6一段琴弦的局部张力,微调其音高,轻松快捷调准空弦音高,使演奏者能顺利进行演奏。
本实用新型弦轴微调器如图1,轴套1是套在弦轴端部,大小要适合,轴套1上有螺栓2用来一方面使轴套1固定套在弦轴上,另一方面也固定了弦钩板3,弦钩板3下部弯成弦钩6,中部铆有一开槽螺帽4,微调螺钉5就上到开槽螺帽4中,用业调整琴弦的张力,达到所需音准。当琴弦由弦轴下来,通过开槽帽板4与弦钩板3上弦钩6,调整微调螺钉5,微调螺钉5顶住琴弦,即达到微调音高目的,其调节灵敏度高,性能稳定,操作方便。
本实用新型是用金属材料如薄铜板、薄铁板、薄不锈钢板等制成。
本实用新型小巧美观,调音快捷,性能稳定,不跑音,灵敏度高,结构简单,易于安装,制造成本低,适用于各种民族拉弦乐器。
