在一个实施例中，蓝牙音箱还包括连接蓝牙模组104的显示装置124。显示装置124用于显示蓝牙音箱的状态信息，例如显示蓝牙音箱处于歌曲播 放模式或通话模式，在蓝牙音箱处于歌曲播放模式时还可显示当前播放歌曲的名称、歌手和剩余时间等信息，在蓝牙音箱处于通过模式时还可显示来电用户名、归属地和通话时长等信息，以便于用户查看。此外，当用户在进行音源的输入选择时，显示装置124还可显示可使用的音源，例如显示蓝牙、USB和AUX IN三种音频来源，显示装置124将用户通过按压播放调节按键所选中的音源标亮显示，蓝牙模组104接收标亮显示的音源输入的音频信号。
此外，蓝牙音箱还包括箱体，蓝牙天线102、蓝牙模组104、电池112和功放模组114均设置于箱体内，数据接口106、按键板108、电源开关110和扬声器116设置于箱体外面表。此外，还可将前级信号放大电路118和充电控制器120设置于箱体内，将麦克风、指示灯、充电接口122和显示装置124设置于箱体外面表。利用箱体保护内部器件，减少被碰坏的风险，提高了蓝牙音箱的使用安全性。
具体地，如图3所示，按键板108、麦克风126和指示灯设置在箱体132顶部的外表面。按键板108包括播放调节按键(由后退键1081和前进键1082组成)、音频控制按键1083、音量减小按钮1084和音量增大按钮1085。指示灯包括音源输入指示灯128和电池电量指示灯130。如图4和图5所示，电源开关110、USB接口1062、AUX IN接口1064和充电接口122设置在箱体132背部的外表面。箱体132开设有喇叭口，扬声器116设置于喇叭口。
上述蓝牙音箱，用户可通过电源开关110控制蓝牙音箱的开启和关闭，操作简便可靠。可通过按键板108发送数据接入切换指令，控制蓝牙模组104进行音源的输入选择，避免在没有蓝牙或蓝牙信号较差的环境时影响蓝牙 音箱的播音效果，使用便利性高。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
