Description

自动吉他弦微调检测装置
技术领域
本发明涉及吉他领域，特别地，是涉及一种吉他调弦装置。
背景技术
吉他又译六弦琴；其面板与背板都是平的，琴身腰部一般无角而往里凹；琴颈很宽，长，指板上有弦枕并装有很多窄而稍向上凸起的金属制的横格，称之为品；现有的吉他在调音的过程中，通常是使用者手动旋转弦钮，通过跟标准音进行比对，进行调节音准；调节琴弦的音准主要跟琴弦的松紧程度有关，由于琴弦在长期的使用者过程中，弦钮可能会出现松动，使得琴弦的松紧状态发生改变，从而使得琴弦的音准被改变；因此，使用者经常需要重新将其校准，在调音方面花费较多的时间。
发明内容
针对上述问题，本发明的目的在于提供一种自动吉他弦微调检测装置，能够自动补偿松弛的吉他弦的松紧状态，从而使得吉他琴弦能够维持在标准音的可接受误差范围值内。
本发明解决技术问题所采用的技术方案是：该自动吉他弦微调检测装置包括固定板、调节板及微调模块；所述固定板上设计有与各琴弦相对应的固定孔，所述琴弦的末端由弦栓卡紧固定在固定孔内；所述调节板设置于固定板的上侧，所述调节板上排列有与各琴弦相正对的滑孔；所述微调模块包括可在所述滑孔内上下滑动的滑柱及支承于滑柱底部的弹簧；所述滑柱的顶面设计有卡置琴弦的弦槽。
作为优选，所述微调模块上设计有电磁感应灯模块，所述电磁感应灯模块包括LED灯、螺线管线圈及环形磁体；所述LED灯固定安装在所述弦槽的下方，所述滑柱内设有与所述滑柱同轴的螺线管线圈，所述螺线管线圈耦合于所述LED灯；所述滑孔的孔壁内设计有环绕所述滑柱的所述环形磁体；进一步地，所述琴弦由内掺散射杂质的半透明尼龙弦构成，以使所述LED灯发出的光照在琴弦内大范围散射，以点亮整根琴弦，提高其艺术表现效果。
作为优选，所述滑柱上设计有刻度线；从而当滑柱与滑孔端面所对应的当前刻度值与初始调校时的刻度值发生明显变化时，使用者可判断该滑柱所对应的琴弦已产生明显失准，有必要对其进行重新调校。
本发明的有益效果在于：对于采用该自动吉他弦微调检测装置的吉他，在校调完各琴弦基准音后，各琴弦枕在所述调节板上的各滑柱的弦枕内，并将各滑柱下压，使各弹簧保持一定的预紧压力；当使用者在长时间使用吉他后，琴弦的松紧度发生变化时，所述弹簧的预紧压力得到释放，以补偿琴弦的松紧度，从而使吉他琴弦能够维持在标准音的可接受误差范围值内。
附图说明
图1是本发明自动吉他弦微调检测装置的主视图。
图2是图1中A处的局部放大图。
图3是本发明自动吉他弦微调检测装置的局部剖视图。
具体实施方式
下面结合附图和实施例对本发明进一步说明：
如图1、图2、图3中实施例所示，该自动吉他弦微调检测装置是一种能够自动补偿松弛的吉他弦的松紧状态，从而使得吉他弦能够维持在标准音的可接受误差范围值内的装置，它包括固定板2、调节板1及微调模块3；所述固定板2上设计有与各琴弦4相对应的固定孔，所述琴弦4的末端由弦栓21卡紧固定在固定孔内；所述调节板1设置于固定板2的上侧，所述调节板1上排列有与各琴弦4相正对的滑孔；所述微调模块3包括可在所述滑孔内上下滑动的滑柱31及支承于滑柱31底部的弹簧32；所述滑柱31的顶面设计有卡置琴弦4的弦槽。
对于采用该自动吉他弦微调检测装置的吉他，在校调完各琴弦4基准音后，各琴弦4枕在所述调节板1上的各滑柱31的弦枕内，并将各滑柱31下压，使各弹簧32保持一定的预紧压力；当使用者在长时间使用吉他后，琴弦4的松紧度发生变化时，所述弹簧32的预紧压力得到释放，以补偿琴弦4的松紧度，从而使吉他琴弦4能够维持在标准音的可接受误差范围值内。
另外，如图3所示，所述微调模块3上设计有电磁感应灯模块，所述电磁感应灯模块包括LED灯51、螺线管线圈52及环形磁体53；当使用者在拨动琴弦4时，琴弦4的震动使得所述滑柱31上下振动，带动所述螺线管线圈52上下振动，从而使其磁通量连续变化，以产生感应电动势，从而点亮所述LED灯51，发出的光照在琴弦4上，能够提高其艺术表现效果。
以上所述仅为本发明的较佳方式，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
