Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The wireless sound box of the present embodiment is specifically a bluetooth sound box, the bluetooth sound box is provided with a controller inside, and a memory arranged to store computer executable instructions, the memory has a computer readable storage medium therein, the computer readable storage medium stores one or more programs formed by a set of computer executable instructions, and when the one or more programs are executed by the controller, the following wireless sound box volume control methods as shown in fig. 1 and fig. 2 are implemented:

the mobile phone is connected with the loudspeaker box through SPE Bluetooth or BLE, when the mobile phone is connected with the loudspeaker box, the loudspeaker box identifies the Bluetooth MAC address of the mobile phone, the Bluetooth MAC address is stored in the preset address of the local flash of the loudspeaker box, and after the mobile phones are connected, a connection list can be formed in the preset address of the local flash of the loudspeaker box.

After the mobile phone is successfully connected with the upper sound box:

1) in the connection process, the mobile phone sends an instruction to control the sound box to implement a volume adjustment action, and the sound box updates the content corresponding to the mobile phone in the connection list to a flash data format of 'flag bit A1+ MAC address + volume step number' at the moment or after the sound box receives the instruction, wherein A1 is preferably a binary character '1';

2) if no command is sent by the mobile phone to perform a volume adjustment action in the connection process, at the moment of disconnection or after disconnection, the sound box queries the item content corresponding to the mobile phone in the connection list, if the flag bit in the item content is A1, the sound box history is subjected to volume adjustment by the mobile phone, data updating is not performed, if the flag bit in the item content is not A1, the item content corresponding to the mobile phone in the connection list is updated to a flash data format "flag bit A2+ MAC address", which indicates that the mobile phone is connected but has no volume adjustment, wherein A2 is preferably a binary character "0".

In the time period that the mobile phone is connected with the loudspeaker box every time and the connection is not successful, the loudspeaker box inquires and sets a connection list in a local flash space of the loudspeaker box:

1) if the Bluetooth MAC address of the current mobile phone is not inquired, the current mobile phone is not connected with the loudspeaker box, and default volume is used;

2) if the Bluetooth MAC address of the current mobile phone has a record in the connection list, directly inquiring a flag bit, and if the flag bit is A2, indicating that the volume of the current mobile phone is not adjusted before, using default volume;

3) if the Bluetooth MAC address of the current mobile phone is recorded in the connection list and the flag bit is found to be A1 through inquiry, which indicates that the volume of the current mobile phone is adjusted last time, the sound box directly reads the volume steps of the corresponding content in the connection list to set the volume of the sound box.

It should be noted that, because the mobile phone generally needs to broadcast immediately after being connected with the bluetooth, and during the bluetooth connection, the bluetooth handshake action needs to occupy a part of time, so the loudspeaker box is required to quickly read and judge whether the mobile phone has been connected and whether the volume of the data has been adjusted in a very short time, and the influence on the user experience caused by the overlong time of connecting the mobile phone to broadcast from the bluetooth is avoided. In order to meet the requirement of the sound box for fast reading and reading judgment of the data, in this embodiment, the following settings are made to ensure: 1) setting a connection list to be stored in a preset address of a local flash of the sound box, and ensuring that data transmission between the sound box and the flash is directly executed locally; 2) setting the time for reading data by the sound box to occur in the time period when the mobile phone is connected with the sound box and the connection is not successful; 3) setting a mark bit in a frame header of a flash data format, setting the mark bit as a binary character, and directly inquiring the mark bit to perform condition classification response when the sound box inquires that the MAC has a record, thereby shortening the operation flow.

The sound box of the embodiment can be replaced by other wireless sound boxes such as WIFI and the like, and is not necessarily limited to a Bluetooth sound box; in this embodiment, a computer, a tablet, or other terminal may be used instead of the mobile phone.

The method of the present embodiment may be implemented by a method that is converted into program steps and apparatuses that can be stored in a computer storage medium and invoked and executed by a controller.
