Description

一种尤克里里
技术领域
本实用新型涉及一种乐器，特别是指一种尤克里里。
背景技术
尤克里里是一种四弦夏威夷的拨弦乐器，发明于葡萄牙盛行于夏威夷，归属在吉他乐器一族。
尤克里里一般包括琴头、琴弦、指板、琴体，所述琴头安装在指板上端，所述琴体安装在指板下端，所述琴头上设有四个用于固定琴弦的固定钮，琴头侧面还设有分别与固定钮相连的调节旋钮，琴头与指板的连接处设有弦枕，所述指板上设有将指板分为若干个品格的品丝，所述琴体的正面上设有琴码和琴桥，所述琴弦的上端固定在固定钮上，所述琴弦的下端跨过琴桥固定在琴码上。
尤克里里由于体型相比较一般的吉他小，适合演奏节奏简单，欢快的音乐，因此广受人们喜爱，但是目前的尤克里里主要靠共鸣箱发声，声音较小，没有音色变化，只能单纯的演奏；而且现在人们喜欢用智能手机来播放伴奏来演奏尤克里里，但是由于智能手机播放的伴奏和尤克里里弹奏的声音是在空气中混音后直接传入人耳，而且还由于智能手机的功放小，这些问题导致智能手机播放的伴奏和尤克里里弹奏的声音不能完美的融合在一起，导致演奏的声音的音质差强人意。
实用新型内容
本实用新型的目的在于提供一种尤克里里，其能配合智能手机中的伴奏进行演奏，并且能保证演奏的音质。
为了达成上述目的，本实用新型的解决方案是：
一种尤克里里，包括尤克里里本体，所述尤克里里本体包括琴头、琴弦、指板、琴体，所述琴体的正面设有琴码和琴桥；所述的一种尤克里里还包括有电路板；所述电路板配合在琴体上；所述电路板设有电源模块、蓝牙音频输入模块、拾音模块、混音模块、音频输出模块；所述电源模块为蓝牙音频输入模块、混音模块、音频输出模块供电，所述蓝牙音频输入模块和拾音模块分别与混音模块的两输入端相连，所述混音模块的输出端与音频输出模块相连；所述拾音模块包含压电式拾音器，所述压电式拾音器设在琴码和琴桥之间；所述音频输出模块包含耳机插座和音频插座，所述耳机插座与混音模块之间设有放大电路，所述耳机插座和音频插座设置琴体的侧面。
所述电路板还设有充电模块，所述充电模块与所述电源模块相连；所述电源模块设有锂电池，所述充电模块设有充电接口，所述充电接口设在琴体的侧面。
所述充电接口为Micro USB接口。
所述拾音模块与混音模块之间连接有音色调节电位器、音量调节电位器。
所述音色调节电位器、音量调节电位器分别配合有旋钮，所述旋钮设在在琴体的正面。
所述电源模块与蓝牙音频输入模块之间设有蓝牙电源开关。
所述琴体上设有共鸣箱。
所述琴体为实心结构。
采用上述技术方案后，本实用新型具有以下效果：
本实用新型使用时，本实用新型可以通过蓝牙音频输入模块将智能手机内的伴奏的第一音频信号通过输入到混音模块，而使用者可以根据伴奏而弹奏尤克里里本体，弹奏尤克里里本体产生的第二音频信号则通过拾音模块输入到混音模块，第一音频信号和第二音频信号在混音模块进行混音形成第三音频信号，第三音频信号通过音频输出模块输出；因此本实用新型能配合智能手机中的伴奏进行演奏，并且由于伴奏的第一音频信号和弹奏的第二音频信号是在混音模块中进行混音，所以可以避免外界环境对第一音频信号和第二音频信号混音时的影响，保证第三音频信号的质量，进而保证演奏的音质。而且本实用新型是通过设在琴桥和琴码之间压电式拾音器来采集弹奏的第二音频信号，可以减少拾音模块采集噪音，保证拾音模块采集的音频信号尽可能为尤克里里本体弹奏的声音。

具体实施方式
为了进一步解释本实用新型的技术方案，下面通过具体实施例来对本实用新型进行详细阐述。
如图1至图5所示，本实用新型揭示了一种尤克里里，其包括尤克里里本体A和电路板B；所述尤克里里本体A包括琴头A1、琴弦A2、指板A3、琴体A4，所述琴体A4设有琴码A41和琴桥A42，所述电路板B配合琴体A4上；所述电路板B设有充电模块1、电源模块2、蓝牙音频输入模块3、拾音模块4、混音模块5、音频输出模块6。
配合图4所示，所述充电模块1与电源模块2相连，所述电源模块2为蓝牙音频输入模块3、拾音模块4、混音模块5、音频输出模块6供电；所述蓝牙音频输入模块3和拾音模块4分别与混音模块5的两输入端相连，所述混音模块5的输出端与音频输出模块6相连。
配合图5所示，具体的，所述电源模块2包括锂电池和电源管理芯片以及电源管理芯片的配套外围电路，所述电源管理芯片的具体型号为AP2000。
所述充电模块1包括充电接口11、充电管理芯片以及充电管理芯片的配套外围电路；所述充电管理芯片的型号为AP5054B；所述充电接口11设在琴体A4的侧面；所述充电接口11优选为Micro USB接口以便适用于现有的安卓系统的智能手机的常见配备的电源线，方便使用者充电。
所述蓝牙音频输入模块3包括蓝牙芯片以及蓝牙芯片的配套外围电路，所述蓝牙芯片的具体型号为AC4605，所述蓝牙音频输入模块用于与智能手机相连并接收智能手机中的伴奏的第一音频信号及将第一音频信号传输给混音模块5。进一步，为减少功耗，所述电源模块2与蓝牙音频输入模块3之间设有蓝牙电源开关31；通过蓝牙电源开关31的通断可以实现蓝牙音频输入模块3的工作与否，从而减少功耗。
所述拾音模块4包括压电式拾音器41以及滤波放大电路，配合图3所示，所述压电式拾音器41设在琴码A41和琴桥A42之间；当使用者弹奏尤克里里本体A时，琴弦A2的振动会传递到琴码A41和琴桥A42，拾音模块4的压电式拾音器41便可以采集使用者弹奏的第二音频信号，而且可以减少拾音模块4采集噪音，保证拾音模块4采集的音频信号尽可能为尤克里里本体A弹奏的声音。进一步，所述拾音模块4与混音模块5之间连接有音色调节电位器42、音量调节电位器43，通过音色调节电位器42、音量调节电位器43可以对拾音模块4采集的第二音频信号进行音色、音量的调节；为便于使用者调节音色、音量，所述音色调节电位器42、音量调节电位器43分别配合有旋钮44，所述旋钮44设在在琴体4的正面。
所述混音模块5包括一音频放大电路，所述音频放大电路采用功率放大器LM386及其配套器件。通过混音模块5，可以将蓝牙音频输入模块3传输的第一音频信号和拾音模块4采集的第二音频信号进行混音形成第三音频信号。
所述音频输出模块6包含耳机插座61和音频插座62，用户可以通过耳机线或音频线接入耳机或者是外置功放扬声器来将混音模块5输出的第三音频信号转为声音进行播放。所述音频输出模块6采用耳机插座61和音频插座62可以将第三音频信号完全传输到耳机或者是外置功放扬声器，避免第三音频信号的损失，尽可能保证耳机或者是外置功放扬声器播放的声音的音质；为了防止耳机线、音频线影响用户的弹奏，所述耳机插座61和音频插座62设在琴体A4的侧面；同时为了保证耳机播放的声音的质量，所述耳机插座61与混音模块5之间设有放大电路，所述放大电路的放大器采用JRC4558。
本实用新型使用时，用户可以将耳机和\或外置的功放扬声器连接到音频输出模块6，用于将声音播放出来；具体的，以用户单独连接外置功放扬声器为例说明本实用新型的使用过程，用户使用时，先将智能手机的蓝牙与本实用新型的蓝牙音频输入模块3连接；然后将智能手机内的伴奏的第一音频信号通过蓝牙音频输入模块3输入到混音模块5，此时用户可以根据伴奏而弹奏尤克里里本体A，用户弹奏时会引起琴桥A42和琴码A41的振动，因此用户弹奏尤克里里本体A产生的第二音频信号便通过拾音模块4传输到混音模块5；第一音频信号和第二音频信号通过混音模块5进行混音后形成第三音频信号输出到音频输出模块6，第三音频信号再通过音频输出模块6输出到外置的功放扬声器外放声音，方便多人聆听，在此过程中，用户可以通过音色调节电位器42、音量调节电位器43调节第二音频信号的音色和音量，而第一音频信号的音量则可以通过智能手机来调节。
进一步，所述琴体A4上可设有共鸣箱，这样用户可以和现有的尤克里里一样进行弹奏，弹奏的声音通过共鸣箱进行放大；当然所述琴体A4也可以为实心结构，即所述琴体A4上不设有共鸣箱，这样用户在使用时，可以通过耳机聆听演奏的声音，将声音限制在耳机内，避免扰民。
上述实施例和图式并非限定本实用新型的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本实用新型的专利范畴。
