Such as: the user responds to the sound addition and subtraction operation by operating the sound addition and subtraction key on the terminal 100.
The terminal 100 may also be a smart device such as a mobile terminal, tablet computer, notebook computer, etc. For example, smart speaker 200 is controlled using an application running on a smart device. The application program, by configuration, can provide various controls to the user through an intuitive User Interface (UI) on a screen associated with the smart device.
A block diagram of the configuration of the intelligent speaker 200 is schematically shown in fig. 1B. As shown in fig. 1B, the smart speaker 200 includes a controller 210, a communicator 220, a sound output module 230, and a power supply 240.
The controller 210 includes a Random Access Memory (RAM) 211, a Read Only Memory (ROM) 212, a processor 213, a communication interface, and a communication bus.

Referring to fig. 2A, an embodiment of the present application provides a network distribution method for an intelligent sound box, including:
starting an intelligent sound box to be distributed with a network;
the terminal starts a distribution network interface, searches for the Bluetooth of the intelligent sound box, and initiates connection with the intelligent sound box;
the terminal can be a mobile phone, a computer or an ipad.
After the intelligent sound box is successfully connected with the terminal, other terminals cannot be connected with the intelligent sound box;
the intelligent sound box sends a request for acquiring the maximum transmission unit to the terminal;
after receiving the request sent by the intelligent sound box, the terminal responds to the request for acquiring the maximum transmission unit.
The terminal may or may not return to the limit size of the maximum transmission unit of the intelligent speaker.
For example, in an andorid system, the limitation of the maximum transmission UNIT (MAXIMUM TRANSMISSION UNIT, MTU) of the andorid device, typically 512 bytes, can be obtained before the bluetooth (ble) is used to transmit data. And for part of terminals and systems, the limit of the maximum transmission unit of the intelligent sound box is not returned.
The user clicks a button for acquiring the wifi list on the terminal, and the terminal sends a request for acquiring the wifi list;
and the intelligent sound box receives a request for acquiring the wifi list sent by the terminal, and decides a transmission mode according to whether the terminal replies to the maximum transmission unit.
If the intelligent sound box does not receive the maximum transmission unit limit replied by the terminal, the existing mode generally adopts the transmission of a ble transmission default transmission size, and the transmission of the ble transmission default transmission size is 23 bytes. When the default MTU is used for transferring data, the time for acquiring the wifi list is very long, so that the wifi list cannot be acquired by using the default MTU, and the user cannot select wifi. Aiming at the condition that the terminal does not reply to the maximum transmission unit, the method and the device use a BLE_WIFI self-adaptive transmission algorithm to transmit WIFI list data, and can meet the acquisition speed of a WIFI list. The specific method comprises the following steps:
referring to fig. 2B, fig. 2B is a flowchart of a ble_wifi adaptive transmission algorithm.
When the intelligent sound box does not receive the maximum transmission unit limit replied by the terminal, acquiring available wifi information in a preset range;
establishing a wifi list according to wifi information;
and calculating the data size of the wifi list, and transmitting the data size of the wifi list to the terminal according to the default transmission size of the ble.
And the terminal receives and records the data size of the wifi list transmitted in the table default transmission size.
For example: the intelligent sound box calculates the data size of the wifi list, namely the data size of the wifi list before being transmitted to the terminal is 1000 bytes, and the data of 1000 bytes is transmitted to the terminal by the transmission size of 23 bytes.
If the data size of the wifi list is smaller than the preset byte, the preset byte can be 512 bytes, the data of the wifi list is transmitted to the terminal by the first forward data size in the wifi list transmission data queue, and the wifi list transmission data queue comprises data sizes which are arranged from small to large.
The wifi list transmission data queue may be {70,134,262,518}, with the unit being bytes. The value of the wifi list transmission data queue represents the size of a data packet transmitted at one time. According to the structure of the ble transport packets, each transport packet is composed of a header (2 bytes), a payload, and a trailer (4 bytes), so the queue data is composed of: the first 2 bytes are packet heads, the effective data loads are 64, 128, 256 and 512 bytes respectively, and the last 4 bytes are packet tails, so that a wifi list transmission data queue {70,134,262,518} is formed.
The terminal continuously receives the data of the wifi list sent by the intelligent sound box until receiving the end mark; calculating the data size of the received wifi list; if the data size of the wifi list transmitted by the intelligent sound box is inconsistent with the data size of the wifi list calculated by the terminal, sending a packet loss message to the intelligent sound box; if the data size of the wifi list transmitted by the intelligent sound box is consistent with the data size of the wifi list calculated by the terminal, displaying the wifi name in the wifi list and sending a non-packet-loss message to the intelligent sound box. After the user checks available wifi in the wifi list, any wifi in the list is selected, a password corresponding to the wifi is input, and the terminal sends a service set identifier and a password for the user to select the wifi to the intelligent sound box.
If the intelligent sound box receives a packet loss message sent by the terminal, judging whether the transmission data size is the last value of a wifi list transmission data queue;
and determining the last value of the wifi list transmission data queue according to the direction of the wifi list transmission data queue. The wifi list transfer data queue is specifically {70,134,262,518}, because transfer of 70 bytes of forward first data size begins, then the last value is 518 bytes of forward last value.
And if the transmission data size is not the last value of the wifi list transmission data queue, retransmitting the data of the wifi list to the terminal by using the next forward data size in the wifi list transmission data queue.
And if the transmission data size is the last value of the wifi list transmission data queue, sending a message of failure in acquiring the wifi list to the terminal.
And if the intelligent sound box receives the non-packet-loss message sent by the terminal, receiving a service set identifier and a password of wifi selected by a user. Connecting the wireless network by using the received service set identification and the password; and after the connection is successful, reporting the successful networking state to the terminal.
The terminal enters a home page to display media resources and the like.
For example: the wifi list transmission data queue is {70,134,262,518}, the data size of the wifi list transmitted to the terminal by the intelligent sound box is 500 bytes, and the data of the wifi list is transmitted to the terminal by the intelligent terminal in 70 bytes. If the terminal receives all the transmitted data and calculates that the received data size is 500 bytes, the data size of a wifi list transmitted to the terminal by the intelligent sound box is consistent with the data size calculated by the terminal, the terminal sends a packet loss-free message to the intelligent sound box, and the intelligent sound box receives a service set identifier and a password of wifi selected by a user. Connecting the wireless network by using the received service set identification and the password; and after the connection is successful, reporting the successful networking state to the terminal. The terminal enters the home page to display media resources. If the terminal receives all the transmitted data and calculates the received data size as 490 bytes, the data size of the wifi list transmitted to the terminal by the intelligent sound box is inconsistent with the data size calculated by the terminal, and the terminal sends a packet loss message to the intelligent sound box. Because 70 is not the last data size of wifi list transmission data queue, intelligent audio amplifier is with the data of 134 byte transmission size retransmission wifi list to terminal until receiving the no packet loss message that the terminal sent, perhaps after the data of wifi list transmission data queue's last data size 518 byte retransmission data list to terminal, still do not receive the no packet loss message that the terminal sent, intelligent terminal sends the message that wifi list acquisition failed to the terminal, and the terminal shows the message that the distribution network failed, and the user can try again and try the distribution network.
If the data size of the wifi list is not smaller than the preset byte, the preset byte can be 512 bytes, and the data of the wifi list is transmitted to the terminal by the first reverse data size in the wifi list transmission data queue.
The wifi list transmission data queue may be {70,134,262,518}, with the unit being bytes. The value of the wifi list transmission data queue represents the size of a data packet transmitted at one time. According to the structure of the ble transport packets, each transport packet is composed of a header (2 bytes), a payload, and a trailer (4 bytes), so the queue data is composed of: the first 2 bytes are packet heads, the effective data loads are 64, 128, 256 and 512 bytes respectively, and the last 4 bytes are packet tails, so that a wifi list transmission data queue {70,134,262,518} is formed.
The terminal continuously receives the data of the wifi list sent by the intelligent sound box until receiving the end mark; calculating the data size of the received wifi list; if the data size of the wifi list transmitted by the intelligent sound box is inconsistent with the data size of the wifi list calculated by the terminal, sending a packet loss message to the intelligent sound box; if the data size of the wifi list transmitted by the intelligent sound box is consistent with the data size of the wifi list calculated by the terminal, displaying the wifi name in the wifi list and sending a non-packet-loss message to the intelligent sound box. After the user checks available wifi in the wifi list, any wifi in the list is selected, a password corresponding to the wifi is input, and the terminal sends a service set identifier and a password for the user to select the wifi to the intelligent sound box.
If the intelligent sound box receives a packet loss message sent by the terminal, judging whether the transmission data size is the last value of a wifi list transmission data queue;
and determining the last value of the wifi list transmission data queue according to the direction of the wifi list transmission data queue. The wifi list transfer data queue may be {70,134,262,518}, because the transfer starts with the reverse first data size 518 bytes, then the last value is the reverse last value 70 bytes.
And if the transmission data size is not the last value of the wifi list transmission data queue, retransmitting the data of the wifi list to the terminal by using the next reverse data size in the wifi list transmission data queue.
And if the transmission data size is the last value of the wifi list transmission data queue, sending a message of failure in acquiring the wifi list to the terminal.
And if the intelligent sound box receives the non-packet-loss message sent by the terminal, receiving a service set identifier and a password of wifi selected by a user. Connecting the wireless network by using the received service set identification and the password; and after the connection is successful, reporting the successful networking state to the terminal.
The terminal enters a home page to display media resources and the like.
For example: the wifi list transmission data queue may be {70,134,262,518}, the data size of the wifi list transmitted to the terminal by the intelligent sound box is 3000 bytes, and the intelligent terminal transmits the data of the wifi list to the terminal in 518 bytes. If the terminal receives all the transmitted data and calculates the data size to be 3000 bytes, the data size of the wifi list transmitted to the terminal by the intelligent sound box is consistent with the data size calculated by the terminal, the terminal sends a packet loss-free message to the intelligent sound box, and the intelligent sound box receives the service set identifier and the password of wifi selected by the user. Connecting the wireless network by using the received service set identification and the password; and after the connection is successful, reporting the successful networking state to the terminal. The terminal enters the home page to display media resources. If the terminal receives all the transmitted data and calculates the data size to be 2800 bytes, the data size of the wifi list transmitted to the terminal by the intelligent sound box is inconsistent with the data size calculated by the terminal, and the terminal sends a packet loss message to the intelligent sound box. Because 518 is not the last value of wifi list transmission data queue, intelligent audio amplifier is again with 262 byte transmission size retransmission wifi list's data to terminal, until receiving the no packet loss message that the terminal sent, perhaps, after the data of wifi list transmission data queue's last data size 70 byte retransmission data list is to terminal, still not receive the no packet loss message that the terminal sent, intelligent terminal sends wifi list acquisition failure's message to terminal, the terminal shows the message of joining in marriage net failure, the user can try again and join in marriage the net.
If the intelligent sound box receives the maximum transmission unit limit replied by the terminal, acquiring available wifi information in a preset range; establishing a wifi list according to wifi information; and transmitting the data of the wifi list with the transmission size of the maximum transmission unit.
For example, if the maximum transmission unit replied by the terminal is limited to 512 bytes, the data of the wifi list is transmitted in 512 byte transmission size.
The terminal receives a wifi list which is sent by the intelligent sound box and is available, and wifi names in the wifi list are displayed.
The user checks any wifi in the available wifi back selection list, and inputs a password corresponding to the wifi.
And the terminal sends the service set identifier and the password of the wifi selected by the user to the intelligent sound box.
The intelligent sound box is connected with a wireless network by using the received service set identification and the password; and after the connection is successful, reporting the successful networking state to the terminal.
The terminal enters the home page to display media resources.
The intelligent sound box is mainly dependent on a network, when the intelligent sound box is used for the first time, a terminal app is required to be used for configuring the network for the intelligent sound box, and in order to optimize user experience, a user can freely select the network to configure the network of the sound box no matter the app on an Android or IOS mobile phone operating system is operated.
