具体实施方式
下面，结合附图以及具体实施方式，对本发明做进一步描述。
结合图1至图3所示，一种电子吉他，其包括琴颈1以及与所述琴颈1连接的琴身2。
所述琴颈1包括支撑板11、多个触摸按键12以及用于指示用户按压相应的触摸按键12显示屏13，触摸按键12和显示屏13固定安装在支撑板11上并且触摸按键12位于显示屏13的下侧边。本实施例的显示屏13可以是LED显示屏或LCD显示屏。多个触摸按键12沿显示屏13的下侧边的长度方向分布，显示屏13上用于显示出指示用户按压相应的触摸按键12的指示块131，每一指示块131所在的移动路径与相应的触摸按键12对应，如果显示屏13采用的是LED显示屏，则每一灯条(即用于显示对应的指示块131)的位置与相应的一个触摸按键12对应。多个触摸按键12也可以制作成一个细长的触摸屏。
所述琴身2包括外壳21、人机交互界面6、控制电路板、扬声器和电源。人机交互界面6安装在外壳21的上表面，具体的，外壳21的上表面开设有一缺口212，人机交互界面6安装在缺口212的底面，为了便于用户观看，人机交互界面6所在的平面与外壳21的后侧壁215所在的平面之间形成的夹角为45°(实际上，角度范围可在10°-165°之间设计)。人机交互界面6可采用电容式触摸显示屏。所述外壳21的前侧壁211上还安装有一用于控制发声效果的摇杆3。
控制电路板、扬声器和电源7安装在外壳21内。所述控制电路板上集成有主控电路、存储器、音源电路和功率放大器，存储器、音源电路、功率放大器、触摸按键12、显示屏13、摇杆和人机交互界面6均与主控电路连接，功率放大器与扬声器连接。触摸按键12和显示屏13可分别通过各自的连接端子与控制电路板相应的连接端子连接。
电源7为扬声器、触摸按键12、显示屏13、人机交互界面6和控制电路板提供工作电压。
所述支撑板11位于外壳21的右侧壁213，显示屏13所在的平面与外壳21的前侧壁211所在的平面形成一夹角，所述夹角为10-160°，本实施例优选为45°。
为了便于收纳和携带，琴颈1与琴身2采用可拆卸的方式连接。具体的，外壳21的右侧壁213开设有一安装通孔2131，支撑板11的一侧向外延伸出一固定件111，所述固定件111通过所述安装通孔2131进入所述外壳21的内部空间，所述固定件111通过螺丝与所述外壳21连接。为了便于拆装琴颈1，所述外壳21的后侧壁215开设有一位置与所述固定件111对应的第一窗口2151，所述第一窗口2151由一第一盖板4封闭，第一盖板4与第一窗口2151卡扣连接。
为了便于取出电源7，所述外壳21的后侧壁215还开设有一第二窗口2152，所述第二窗口2152由一第二盖板5封闭，第二盖板5与第二窗口2152卡扣连接；所述电源7固定连接在所述第二盖板5上。本实施例的电源7可采用市面上买到的移动电源，从而提高通用性。电源7可通过USB接口与控制电路板连接。
为了便于用户舒适的使用，所述外壳21的下表面设有用于放置用户大腿的凹槽214。
本实施例的使用过程如下：
将本实施例的电子吉他放置在大腿上，即凹槽214放在大腿上，通过人机交互界面6选择歌曲，选择歌曲后，用户就可以直接低头看显示屏13上的掉点指示(如图1所示，掉点指示可用指示块131进行提示)，当指示块131下落至相应的触摸按键12时，用户按压相应的触摸按键13，以使控制电路根据触摸按键12的信号，驱动扬声器发出相应的吉他声。用户还可以通过拨动摇杆3往上、下、左、右方向摆动，以使扬声器配合吉他声发出特殊的音效效果，例如颤音、弯音、扫弦音等。本实施例的发声原理与申请号为CN201410312842.0的中国发明专利申请公开的一种弓弦乐器弹奏指导装置基本相同，即指示块掉落至LED显示屏底部时，用户按压触摸按键12，主控电路接收到按压信号后，根据存储卡内的MIDI文件以及能够发出电子吉他声音源电路，驱动功率放大器和扬声器发出相应的声音。
另外，还可以将上述实施例的摇杆3替换为按键。例如，在外壳的前侧壁上安装有一用于控制发声效果的按键组，所述按键组与控制电路板电性连接。通过按压按键，也可以达到制造特殊音效的效果。
实施例二
如图4所示，本实施例与实施例一的区别在于：琴身2的外壳的前侧壁不安装摇杆或按键组，而是在琴身2的外壳的左侧壁安装一手柄8。所述手柄8上设置有用于控制发声效果的按键组，所述按键组与控制电路板电性连接。琴颈1也同样位于琴身2的右侧。使用时，用户可用右手握持手柄8，并根据需要按压按键组，以发出特殊吉他声的效果。
本发明完全颠覆了现有的电子吉他的弹奏方式，现有的电子吉他在弹奏时，需要用户根据品位点用左手按压所需弹奏的弦，然后用右手弹奏所述弦，才能发出相应的吉他声，弹奏方式是二维的。而本发明只需要用户按压触摸按键即可发出吉他声，弹奏方式是一维的，操作十分方便。
对于本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及变形，而所有的这些改变以及变形都应该属于本发明权利要求的保护范围之内。
