Description

一种三维活动连接键盘电子琴 技术领域
本发明涉及一种电子琴，尤其是键盘类电子琴。
背景技术
常规电子琴通常为一字横排键盘，不仅笨拙难以携带，且必须放置在一个架子或台面上演奏；新近出现的可卷起键盘的电子琴，演奏时也必须将键盘平展在一个台面上演奏，而不能边行走，边演奏。
键盘乐器中的手风琴，具有可携带站立、行走演奏的功能，然而其左手与右手为完全不同的结构，这使得手风琴只能作为一门专项演奏技能去学习，而不宜于作为通识音乐教育的乐器。我们需要一种既具有像钢琴、电子琴一样的常规键盘，可以放置在平面上演奏，又能像手风琴一样方便站立、行走演奏，还便于收纳提携；既具有独特演奏特点，又能够与学习常规钢琴演奏技法自然衔接的新型乐器。
另外，现行常规电子琴均为全键盘同一种音色，切换音色时，全键盘所有的音都一起变化，每只手不能演奏不同音色，无法实现一个人演奏两件乐器的演奏效果。
现行的电子琴仅仅是演奏乐器，而不能作为音乐的播放设备，从而不能在音乐教学，特别是儿童音乐通识教育中承担起音乐欣赏、音乐模仿的教学任务。
发明内容
为了解决以上问题，本发明采用一种三维活动连接键盘电子琴，包括左键盘、右键盘、高音喇叭、低音喇叭、肩背带、存贮设备、录音键、 耳机插孔，左右键盘上均设有独立的乐器音色选择键、音区调整键、音量调整推杆，琴上设有音乐点播模式键。左右两块键盘可三维活动连接；左右两键盘呈一字型横排连接时，同常规电子琴；左右两键盘呈竖排连接时，为双排键电子琴；左右两键盘呈纵向对扣连接时，便于提拎携带。在竖排连接位置时，左右两键盘后部之间形成小于180度的夹角，在左右键盘下部两个斜面处分别设置磁块a、b以固定左右键盘。左右键盘之间由软数据线连接；左右键盘内设有无线通讯模块、存贮设备和USB接口，无线通讯模块可采用蓝牙、WIFI方式以实现数据更新。
所述三维活动连接为铰链连接，铰链包括铰链轴和连接铰链轴的左右连接轴，左右键盘与铰链连接，即左右连接轴插入左右键盘边侧孔中，通过弹性卡环将左右连接轴与左右键盘活动连接，左右键盘既可以绕铰链轴向上转动，形成横向一字键盘，也可以绕铰链轴向下转动，形成竖向双排键盘。在形成竖向双排键盘状态时，左右键盘又可以以连接轴为中心上下旋转：向下旋转左右两键盘后部之间形成小于180度的夹角状态，向上旋转则形成键盘对扣状态。
所述三维活动连接还可以为磁块、尼龙粘扣或插接扣连接，在左右键盘需要拼接贴合的侧面设置磁块、尼龙粘扣或插接扣，实现左右键盘的三维活动连接。
所述肩背带设置于左右键盘后部，肩背带与键盘的上端连接点位于居中一侧，下端连接点位于居外一侧。
本发明的有益效果是：三维活动连接键盘电子琴既包含了最适宜幼儿音乐通识教育的钢琴式键盘，又能够背在胸前站立、行走演奏，便携方便。特别是背在胸前双手演奏的模式，对于活泼好动，坐不住的孩子来说，可以极大地提高孩子的乐器接触率；行走演奏的方式可以使幼儿器乐集体课的课堂组织发生深刻的变化——教学组织灵活性、生动性远远高于排排坐学习。重要的是，竖向演奏方式与横向演奏方式对于人手而言，手的基本演奏模式没有改变，从而实现了与未来学习钢琴演奏的自然衔接。特别是键盘乐器的排列是天然的乐理教具，可以实现音乐知 识的学习与演奏技能的学习良好结合。双手分控的音色、音量可以实现演奏中类似于两个演奏家演奏不同乐器的效果。这一性能使得这一乐器不仅仅适用于儿童器乐学习中的集体合奏，也将成为业余音乐娱乐的最佳乐器选择。

具体实施方式
以下实施例用于说明本发明，但不用来限制本发明的范围。
参照附图1-13，一种三维活动连接键盘电子琴，包括左键盘(1)、右键盘(2)、肩背带(13)、存贮设备(2)、录音键(23)、耳机插孔(20)、高音喇叭(25)、低音喇叭(26)，所述三维活动连接为铰链(3)连接，铰链包括铰链轴(4)、与铰链轴连接的左连接轴(5)和右连接轴(6)，左右键盘与铰链(3)连接，即左右连接轴插入左右键盘下部孔(7)中通过弹性卡环(8)将左右连接轴与左右键盘活动连接，左右键盘既可以绕铰链轴向上转动，构成与常规钢琴、电子琴相同的一字型键盘电子琴，可以平放在台面上弹奏；左右键盘也可以绕铰链轴向下转动，构成对称排列的双键盘电子琴，配合肩背带(13)，所述双键盘电子琴可以站立行走演奏；左右键盘纵向连接，两键盘相对扣合，则可方便收纳、提拎携带。左右两键盘相对为双排键连接位置时，左右两键盘后部之间形成小于180度的夹角A，在左右键盘下部两个斜面处分别设置磁块a(9)和磁块b(10)以固定左右键盘。
所述三维活动连接还可以为磁块(11)、尼龙粘扣或插接扣(12)连接，在左右键盘需要拼接贴合的侧面设置磁块、尼龙粘扣或插接扣(12)，实现左右键盘的三维活动连接。
左右两键盘相对为双排键连接位置时，左右两键盘后部之间形成小于180度的夹角A，在左右键盘下部两个斜面处分别设置磁块以固定左右键盘。以满足演奏时人与键盘形成舒适的角度。
所述肩背带(13)分别设置于左右键盘后部，每个肩背带的第一连接端(14)和第二连接端(15)的位置相互错开，第一连接端(14)位于居中位置，第二连接端(15)位于居外位置，以避免肩背带从肩部滑落。
左右键盘上均设有乐器选择键(18)、音区调整键(16)、音量调整推杆(21)，每块键盘可选择各自的乐器音色、音区及音量，从而实现一人双手演奏如两个演奏员合奏般的多乐器合奏效果。将音色/音乐切换键(19)设在音色模式下，乐器选择键为选择乐器音色的功能；设在音乐模式下，则乐器选择键的功能变为播放该种乐器的乐曲，从而把电子琴变为一部 按乐器进行曲目分类的音乐播放机。左右键盘之间由软数据线连接，键盘内设有无线通讯模块、存贮设备接口，无线通讯模块可采用蓝牙、WIFI方式进行数据更新，内置或外插的存贮器，可实现更新、添加琴内音色库、节奏型库、欣赏乐曲库及保存个人演奏，通过无线通讯技术可实现存贮器的选程控制更新。
虽然，上文中已经用一般性说明及具体实施例对本发明作了详尽的描述，但在本发明基础上，可以对之做一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明精神的基础上所做的这些修改或改进，均属于本发明要求保护的范围。
