Description

乐器弹奏指导装置 技术领域
本实用新型涉及一种对乐器提供弹奏指导的电子装置。 背景技术
学弹钢琴、 电子琴等乐器时， 要能读懂琴谱， 找到正确琴键， 以及在弹现 节拍时同时考虑下一节拍。 要弹得流畅， 这三种处理必须同时进行， 而没经过 长时间训练的人是不可能做到的。 初学者往往不熟悉琴谱、 琴键， 不会控制节 奏， 出错的时候也得不到及时的纠正， 导致弹奏的过程枯燥乏味， 缺乏效率， 也难以体会到自己弹出动听音乐的乐趣。 发明内容
本实用新型所要解决的技术问题是提供一种能对自我练习乐器弹奏提供即 时指导的装置。
本实用新型解决其技术问题所采用的技术方案是： 提供一种乐器弹奏指导 装置， 其包括单片机， 与单片机相连的储存卡、 选择控制单元以及发光二极管 显示板， 所述发光二极管显示板对应于琴键设置于乐器的压键板上。
进一步地， 所述发光二极管显示板包括印刷电路板、 控制芯片和与琴键对 应的若干发光二极管组， 每一发光二极管组包括若干垂直排列的发光二极管。
进一步地， 每一发光二极管组中的发光二极管个数为 16个、 24个或 32个。 进一步地， 所述发光二极管组的组数为 25组、 37组、 44组、 61组或 88组。 进一步地， 所述选择控制单元为选择键或触控屏。 进一步地， 所述储存卡为安全数码卡或通用串行总线接口卡。
本实用新型的有益效果是： 用户通过选择控制单元选出想要弹奏的曲子， 单片机从储存卡中读出弹奏数据， 并分析弹奏数据， 得出应弹的琴键位置， 位 置数据输送到发光二极管显示板， 用户只要能连续按显示板上的发光二极管的 指示按下相应的琴键， 便可弹奏出曲子。 对于初学者来说， 达到了增强学习效 果的目的， 同时获得了独立弹奏曲子的乐趣。 附图说明
图 1为本实用新型乐器弹奏指导装置的原理示意图；
图 2为本实用新型乐器弹奏指导装置的效果示意图。 具体实施方式
请参照附图 1和图 2, 本实用新型乐器弹奏指导装置包括单片机 10、 储存 卡 20、 选择控制单元 30以及 LED (发光二极管）显示板 40。 单片机 10用于数 据处理， 分析输入和生成输出。 储存卡 20用于储存弹奏数据， 通过单片机 10 读写， 可为 SD (安全数码)卡或 USB (通用串行总线)接口卡。 选择控制单元 30与 单片机 10相连， 用于输入用户控制信息， 例如曲目选择， 熟读选择等， 可为选 择键或触控屏。 LED显示板 40用于显示琴键弹奏的指导信息， 对应于钢琴琴键 1设置于钢琴的压键板 2上，从琴键的 C2 (中央 C向左 24键）开始到 C7键（中 央 C向右 36键） ， 横跨共 61键。
LED显示板 40包括印刷电路板、 控制芯片 （图未示）和与钢琴琴键——对 应的若干发光二极管组。发光二极管组的组数根据乐器型号而定，如可为 25组、 37组、 44组、 61组或 88组， 在本实施例中为 61组。 每一发光二极管组包括 16个垂直排列的发光二极管 3 (每组发光二极管个数可升级到 24个、 32个或更 使用时， 接上电源， 用户通过选择控制单元 30选出想要弹奏的钢琴曲， 单 片机 10从储存卡 20中读出弹奏数据， 并分析弹奏数据， 得出应弹的琴键位置, 并按弹奏速度加以调节。 位置数据输送到 LED显示板 40, LED显示板 40的控 制芯片会在相应琴键上方同时点亮该发光二极管组最上方与最下方的两个发光 二极管，并在 1至 3秒 (速度可设定）内把最上方发光点向下移动到达该组最下方 (图 2 中的箭头即下移的发光二极管） 。 在下降的时间内， 用户应借鉴最下方 发光点的位置将手移动到位。 当下移的发光点到达该组最下方已点亮的发光二 极管时， 其发光颜色会改变， 告知用户在此时应按下该发光二极管组对应的琴 键。 用户只要能连续按发光二极管的指示按下相应的琴键， 便可弹奏出钢琴曲。 对于初学者来说， 达到了增强学习效果的目的， 同时获得了独立弹奏乐曲的乐 趣。
以上所述仅为本实用新型的较佳实施例而已， 并不用以限制本实用新型， 凡在本实用新型的精神和原则之内所作的任何修改、 等同替换和改进等， 均应 包含在本实用新型的保护范围之内。
