小度a1拆卸教程
顶部与上部都有固定螺丝下盖拆解撕开防滑垫就可以看到4颗十字螺丝
将螺丝取下后即可将底壳与中段分离，可以看到电源连接线
将电源线拿下后底壳就可以分离底壳了。

拿出白色底盖，DC插座PCB通过插头连接，黑色锥形反射板由4颗十字螺丝固定，拧开。

上盖拆解顶部触控面板沿缝隙将盖子挑起，顶盖为卡扣设计，翘起时不要用过于尖锐的东西不然容易留有撬痕。

按钮面板拿下后，可以看到4颗十字螺丝。

螺丝去掉后可以拿出按钮PCB，将底部的排线连接打开后即可拿下顶部。

音箱腔体两边拆解完成之后，就可以把音箱腔体拿出来，PCB在音箱腔体的侧面，两侧还有低音振膜，底部为音箱的喇叭单元。

4. 其他故障蓝牙音箱的其他故障可能涉及到电源电路、信号处理电路等部分。

对于这些故障，建议寻求专业维修人员的帮助，以确保有效解决问题。

三、维修步骤1. 确认故障点在进行维修之前，首先需要准确定位故障点。

通过全面的故障诊断，确定是电源模块、音频输入电路、音频输出电路还是蓝牙模块等部分出现了问题。

2. 准备工具进行电路维修需要准备一些基本的工具，例如万用表、焊接工具、电路图等。

确保工具的正常状态，以便进行精确的维修工作。

3. 检查元件在维修前，需要检查电路板上的元件是否有烧毁或松动的情况。

特别需要注意焊点是否牢固，如有松动需及时进行焊接修复。

4. 更换故障元件根据故障点的确认，对出现问题的电路元件进行更换。

在更换时，应选择与原件参数相匹配的替代元件，确保其能正常工作。

5. 连接调试在更换元件后，重新连接音频输入输出、电源模块及蓝牙模块等部分。

进行一次全面的检查，确保每个部分连接正常，电路板没有其他故障。

6. 测试运行维修完成后，进行一次全面的测试运行，验证修复效果。

先科W4无线音响使用说明书

先科W4无线音响使用说明书xxxx蓝牙音箱的连接方法一般是如下操作：在关机的状态下按开机键5秒以上直到红蓝灯交替闪烁，这时进入配对状态，然后打开手机蓝牙，搜索蓝牙设备，找到相对应的设备名，配对连接即可。

一般配对连接成功后，只要打开手机音乐播放器就可以使用蓝牙。

拆电池或者功放板：在xx蓝牙音响的反面，有一层双面胶垫，用指甲揭开，就可以看到垫子下面的紧固螺丝，一共三个，把螺丝拧掉，就可以看到锂电池和蓝牙功放板，功放板和喇叭之间通过一个硬币大小的孔联通的，拆喇叭：用钩子勾住，就可以揭开面罩（涂了点胶），喇叭是用胶水和金属音箱外壁粘死的，需要用小刀延边子划一圈，电吹风加热粘胶，再用小起子，一点点撬，就可以取下来了。
