The angle sensor 31 may include at least one of a gravity-sensing gyroscope and a mechanical rotary encoder. Therefore, except for the play mode of the bluetooth speaker 3 switched by the switching module 13, the bluetooth speaker 3 can also switch the play mode according to the placement state of the bluetooth speaker by setting the angle sensor 31, so that the bluetooth speaker 3 is more intelligent.

In an example, when the bluetooth speaker 3 is just turned on, the angle sensor 31 detects that the bluetooth speaker 3 is in a standing state, and the processing module 15 sends the audio signal to the directional speaker 12 for playing; when bluetooth speaker 3 just started, angle sensor 31 detects that bluetooth speaker 3 is in the state of keeping flat, and processing module 15 sends audio signal to spherical wave speaker 11 and plays. That is to say, when the bluetooth speaker 3 is just turned on, the play mode of the bluetooth speaker 3 is switched by default through the angle sensor 31, and the processing module 15 automatically switches the play mode of the bluetooth speaker 3 based on whether the bluetooth speaker 3 is in a flat or vertical state; when the mechanism for switching the play mode of the bluetooth speaker 3 through the angle sensor 31 conflicts with the mechanism for switching the play mode of the bluetooth speaker 3 through the switching module 13, the mechanism for switching the play mode of the bluetooth speaker 3 through the angle sensor 31 fails, and at this time, the mechanism for switching the play mode of the bluetooth speaker 3 through the switching module 13 is used as a criterion.

To sum up, the bluetooth speaker of this application passes through spherical wave speaker, directive property speaker and the setting of switching module, according to the mode switch of switching module, passes through spherical wave speaker or directive property speaker with the audio signal that bluetooth module received and plays alone, perhaps plays simultaneously through spherical wave speaker and directive property speaker to be applicable to the application scene of pluralism. In addition, bluetooth speaker is applicable to and hand-carries through rechargeable battery and bluetooth module's setting, and it is various to be suitable for the scene. In addition, bluetooth speaker still can switch the playback mode according to bluetooth speaker's the state of putting through angle sensor's setting, makes bluetooth speaker more intelligent.
