Description

具有 LCD弹奏指导装置的电子琴 技术领域
本实用新型涉及一种具有 LCD弹奏指导装置的电子琴。
背景技术
使用电子琴弹奏音乐时， 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。
实用新型内容
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电子琴弹奏提供 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： 提供一种具有 LCD弹奏 指导装置的电子琴， 其包括电子琴琴体， 单片机， 存储器， 以及设置在电子琴 琴体的琴键键盘上的 LCD触摸显示屏， LCD触摸显示屏的横向长度与琴键键盘 的横向长度的相等； 琴键键盘、 LCD触摸显示屏、 存储器分别与单片机连接。
进一步地， 琴键键盘包括 25个琴键或 30个琴键或 44个琴键或 61个琴键。 进一步地， 所述存储器为 FLASH存储卡或 SD存储卡。
进一步地， 电子琴琴体的调控功能按键也与单片机连接。 进一步地， LCD触摸显示屏与琴键键盘的夹角为 90° 至 180° 。 本实用新型的有益效果是:用户通过 LCD触摸显示屏选出想要弹奏的曲子， 单片机从存储器中读出弹奏数据， 并分析弹奏数据， 得出应弹的琴键位置， 位 置数据输送到 LCD触摸显示屏显示， 用户只要能根据 LCD触摸显示屏的指示 连续按下相应的琴键， 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， 同时获得了不需读琴谱， 独立弹奏曲子的乐趣。 附图说明
图 1为本实用新型具有 LCD弹奏指导装置的电子琴的原理方框图； 图 2为本实用新型具有 LCD弹奏指导装置的电子琴的效果示意图； 图 3为图 2的 A向示意图。 具体实施方式
请参照图 1、 图 2和图 3, 本实施例具有 LCD弹奏指导装置的电子琴， 其 包括电子琴琴体， 单片机 10, 存储器 30, 以及设置在电子琴琴体的琴键键盘 40 上的 LCD触摸显示屏 20。 LCD触摸显示屏 20的横向长度与琴键键盘 40的横 向长度相等。 琴键键盘 40、 LCD触摸显示屏 20、 存储器 30分别与单片机 10连 接。 本实施例的琴键键盘 40包括 25个琴键 (也可以是 25、 44或 61个琴键， 甚至更多数量的琴键）， 所述琴键与现有技术相同， 包括白键 401和黑键 402。 本实施例的存储器 30采用 FLASH存储卡（也可以采用 SD存储卡）。 本实施例 的电子琴琴体的调控功能按键 50也与单片机 10连接。
为了便于用户观看， LCD触摸显示屏 20与琴键键盘 40的夹角为 145° (实 际上， 其夹角范围在 90。 至 180。 即可）。 单片机 10用于数据处理， 分析输入和生成输出。 存储器 20用于储存弹奏 数据， 通过单片机 10读写。 LCD触摸显示屏 20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， 还用于显示琴键弹奏的指导信息， 对应于琴键键盘 40上的琴键位置。 调控功能按键 50也与单片机 10连接， 通过 LCD触摸显示屏 20也可以设置调控功能按键 50对应的功能。
使用时， 接上电源， 用户通过 LCD触摸显示屏 20选出想要弹奏的钢琴曲， 单片机 10从存储器 30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 LCD触摸显示屏 20, LCD触摸 显示屏 20会在相应琴键上方同时显示最上方与最下方的两个指示光点， 分别是 光点 201和光点 202, 并在 1至 3秒 (速度可设定）内把最上方光点（即光点 201 ) 向下移动到达对应的最下方光点（即光点 202 )。 在下降的时间内， 用户应借鉴 光点 202的位置将手移动到位。 当下移的光点 201到达对应的光点 202时， 其 发光颜色会改变， 告知用户在此时应按下该光点 202对应的琴键。 用户只要能 连续按 LCD触摸显示屏 20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。
此外， 本实施例是由 LCD触摸显示屏 20、 单片机 10、 存储器 30构成的弹 奏指导装置， 与电子琴琴体构成一新型完整的电子琴。
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。
