Detailed Description
The core of the invention is to provide a volume adjusting method, an adjusting system and a device, and a user only sends a volume adjusting instruction to one intelligent sound box, so that each intelligent sound box can synchronously adjust the volume at the same time, and the requirements of the user are met.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flow chart of a volume adjusting method provided by the present invention, which is applied to an intelligent sound box, and the method includes:
S11: determining clock delay between the intelligent sound box and each intelligent sound box in the same network with the intelligent sound box;
The applicant considers that clocks of all intelligent sound boxes in the same network may be inconsistent, and if all intelligent sound boxes adjust the volume according to the clocks of the intelligent sound boxes receiving the volume adjustment instruction, the intelligent sound boxes cannot be ensured to adjust the volume at the same time. For example, in each intelligent audio amplifier in the same network deployment, there may be first intelligent audio amplifier when the clock at the current moment is 8, the clock at the current moment of second intelligent audio amplifier is 8 time 1 minute, the clock at the current moment of third intelligent audio amplifier is 7 time 59 minutes, if 1 timesharing intelligent audio amplifier adjusts self volume to preset volume according to volume adjustment instruction when the user sets for 8, after the user sends volume adjustment instruction to first intelligent audio amplifier, first intelligent audio amplifier sends volume adjustment instruction to second intelligent audio amplifier and third intelligent audio amplifier again, because the user is according to the clock sending volume adjustment instruction of first intelligent audio amplifier, first intelligent audio amplifier is 8 time 1 minutes after 8 minutes, and second intelligent audio amplifier is 8 time 1 minutes, then second intelligent audio amplifier can carry out the regulation of volume immediately, the third intelligent audio amplifier needs to pass through two minutes, can carry out the regulation of volume after 1 minute to 8 time 1 minute of self clock, first intelligent audio amplifier, second intelligent audio amplifier and third intelligent audio amplifier all carry out the regulation of time at 8 minutes, can's the sound amplifier is still not carried out the regulation of three time, and the actual audio amplifier is still can't be satisfied because the sound amplifier is still can't be adjusted to the sound amplifier to the actual demand of the user.
The method is applied to intelligent sound boxes in networking, each intelligent sound box can determine clock delay between the intelligent sound box and each intelligent sound box in the same networking, and as the example above, the first intelligent sound box is delayed for 1 minute compared with the second intelligent sound box, and the first intelligent sound box is delayed for-1 minute compared with the third intelligent sound box, so that the clock delay between the intelligent sound boxes can be determined.
It should be noted that the same network may be, but not limited to, under the same wifi (wireless network communication technology) coverage area.
S12: when receiving the volume adjustment instruction, determining a first volume adjustment time of the intelligent sound box based on the volume adjustment instruction, and setting a second volume adjustment time corresponding to each intelligent sound box in the network based on clock delay and the first volume adjustment time;
When receiving the volume adjustment instruction, the intelligent sound box determines the first volume adjustment time of the intelligent sound box based on the volume adjustment instruction, namely the intelligent sound box adjusts the volume based on the volume adjustment instruction at the first volume adjustment time, and then sets the second volume adjustment time of each intelligent sound box according to the clock delay of each intelligent sound box in the networking.
S13: and sending the volume adjustment instruction and each second volume adjustment time to each intelligent sound box in the networking in a one-to-one correspondence manner, so that the volume of the intelligent sound box and each intelligent sound box in the networking can be adjusted simultaneously based on the volume adjustment instruction when the volume adjustment time corresponding to the intelligent sound box and the intelligent sound box in the networking is based on the volume adjustment instruction.
After setting the second volume adjustment time of each other intelligent sound box in the networking, the intelligent sound box sends the volume adjustment instruction and the second volume adjustment time to the corresponding intelligent sound box, so that the intelligent sound box adjusts the volume when the first volume adjustment time is up to the first volume adjustment time based on the volume adjustment instruction, each other intelligent sound box adjusts the volume according to the second volume adjustment instruction corresponding to the intelligent sound box, and based on the second volume adjustment instruction, each intelligent sound box including the intelligent sound box in the networking can adjust the volume simultaneously, and synchronous adjustment is realized.
Of course, the foregoing is merely an example, and an actual user may not set a specific time for adjusting the volume of the intelligent sound box, may immediately adjust the volume, or may always adjust the volume after receiving the volume adjustment command through a preset interval time, and may specifically adjust the volume according to the user's setting, so as to ensure that each intelligent sound box simultaneously adjusts the volume.
When receiving the volume adjustment instruction and the second volume adjustment time sent by other intelligent sound boxes, the self-timer can directly adjust the volume based on the volume adjustment instruction when the self-timer reaches the second volume adjustment time.
In summary, in the application, the user only sends the volume adjustment instruction to one intelligent sound box, so that each intelligent sound box can synchronously adjust the volume at the same time, and the requirement of the user is met.
Based on the above embodiments:
As a preferred embodiment, after determining the clock delay between itself and each smart speaker in the same network as itself, the method further comprises:

when receiving the volume adjustment instruction, determining a first volume adjustment time of the volume adjustment instruction based on the volume adjustment instruction, and setting a second volume adjustment time corresponding to each intelligent sound box in the network one by one based on the clock delay and the first volume adjustment time, wherein the method comprises the following steps:
When receiving the volume adjustment instruction, determining the first volume adjustment time of the intelligent sound box based on the volume adjustment instruction, and setting the second volume adjustment time corresponding to each intelligent sound box in the network based on the clock delay, the transmission delay and the first volume adjustment time.
The applicant considers that when data transmission is performed between the intelligent sound box receiving the volume adjustment instruction sent by the user and other intelligent sound boxes in the network, certain transmission delay may exist, that is, when the intelligent sound box sends the volume adjustment instruction to the other intelligent sound boxes, the other intelligent sound boxes need to receive the volume adjustment instruction after certain transmission delay, which also causes that each intelligent sound box cannot perform volume adjustment at the same time.
For example, after the first intelligent sound box receives the volume adjustment instruction, the second volume adjustment time of the second intelligent sound box and the second volume adjustment time of the third intelligent sound box are generated, the second volume adjustment time of the second intelligent sound box is sent to the second intelligent sound box, the transmission delay between the second intelligent sound box and the first sound box is between the time when the second intelligent sound box receives the second volume adjustment instruction of the second intelligent sound box and the second intelligent sound box, the second volume adjustment time of the third intelligent sound box is sent to the third intelligent sound box, the transmission delay between the third intelligent sound box and the first intelligent sound box is between the time when the second volume adjustment instruction is received by the third intelligent sound box and the third intelligent sound box, if the volume adjustment is performed immediately when the volume adjustment instruction is received by a user, the first intelligent sound box can be caused to receive the volume adjustment instruction, but due to the transmission delay between the second intelligent sound box and the first intelligent sound box and the transmission delay between the third intelligent sound box, the second intelligent sound box and the third intelligent sound box can be adjusted after the volume adjustment instruction is received, and the second intelligent sound box and the third intelligent sound box cannot be simultaneously transmitted between the second intelligent sound box and the third intelligent sound box.
In order to solve the technical problems, the application determines the clock delay between the intelligent sound box and the network, and also determines the transmission delay between the intelligent sound box and the network, thereby setting the second volume adjusting time of other intelligent sound boxes in the network according to the clock delay and the transmission delay, and further ensuring that the intelligent sound boxes can adjust the volume at the same time.
As a preferred embodiment, when receiving the volume adjustment command, determining a first volume adjustment time of the user based on the volume adjustment command, and setting a second volume adjustment time corresponding to each intelligent speaker in the network one by one based on the clock delay, the transmission delay and the first volume adjustment time, including:
determining the maximum transmission delay in the transmission delays between the intelligent sound box and each intelligent sound box in the networking;
When receiving the volume adjustment command, determining a first volume adjustment time of the intelligent sound box based on the volume adjustment command and the maximum transmission delay, and setting a second volume adjustment time corresponding to each intelligent sound box in the network based on the clock delay, the maximum transmission delay and the first volume adjustment time.
In order to ensure that all intelligent sound boxes can perform volume adjustment simultaneously, the maximum transmission delay in the transmission delays of all intelligent sound boxes and the intelligent sound boxes is determined, so that the first volume adjustment time and the second volume adjustment time are set according to the maximum transmission delay.
As a preferred embodiment, when receiving the volume adjustment command, determining a first volume adjustment time of the volume adjustment command based on the volume adjustment command and the maximum transmission delay, and setting a second volume adjustment time corresponding to each intelligent speaker in the network one by one based on the clock delay, the maximum transmission delay and the first volume adjustment time, comprising:
determining a current clock of the self when receiving a volume adjustment instruction;
determining a first volume adjustment time by a first formula based on the current clock, the volume adjustment instruction and the maximum transmission delay;
The first formula is:
TC1=T0+Ttm+T;
Wherein T C1 is a first volume adjustment time, T 0 is a current clock, T tm is a maximum transmission delay, and T is a preset additional delay;
Determining second volume adjustment time corresponding to each intelligent sound box in the networking one by one through a second formula based on the clock delay and the first volume adjustment time;
The second formula is:
TCn=TC1+Tdn
Wherein, T Cn is the second volume adjustment time of the nth intelligent sound box, T dn is the clock delay between the nth intelligent sound box and itself, and n is a positive integer greater than 1 but not greater than the total number of intelligent sound boxes in the network.
In this embodiment, when determining the first volume adjustment time of the current clock, after receiving the volume adjustment instruction, the current clock is first determined, and the maximum transmission delay is added to the current clock, and then the preset additional delay is set as the first volume adjustment time, where the current clock is the time when the current clock receives the volume adjustment instruction, and the maximum transmission delay is the time when each intelligent sound box can be guaranteed to receive the volume adjustment instruction, and the preset additional delay is added, where the preset additional delay can be, but is not limited to, the time when the user sets the desired delay to perform volume adjustment, and also can be the preset additional delay set to ensure that each intelligent sound box can perform volume adjustment simultaneously.
The first volume adjusting time is added with the clock delay of the nth intelligent sound box to be the second volume adjusting time of the nth intelligent sound box, so that the volume of the nth intelligent sound box is adjusted based on the volume adjusting instruction when the clock of the nth intelligent sound box reaches the second volume adjusting time of the nth intelligent sound box, and based on the volume adjusting instruction, the volume adjustment of each intelligent sound box is ensured when the clock of the nth intelligent sound box reaches the second volume adjusting time of the nth intelligent sound box, and the synchronous volume adjustment of each intelligent sound box is realized.
As a preferred embodiment, determining clock delays between itself and respective intelligent speakers in the same network as itself, and determining transmission delays between itself and respective intelligent speakers in the network, comprises:
Sending heartbeat signals to each intelligent sound box in the same network with the intelligent sound box, wherein the heartbeat signals comprise first time stamps for sending the heartbeat signals by the intelligent sound box;
judging whether feedback heartbeat signals sent by all intelligent sound boxes in the networking are received or not, wherein the feedback heartbeat signals comprise first time stamps, second time stamps when the heartbeat signals are received and third time stamps when the feedback heartbeat signals are sent;
Adding a fourth time stamp when the feedback heartbeat signal is received by the intelligent loudspeaker box in the feedback heartbeat signal sent by each intelligent loudspeaker box;
And determining clock delay and transmission delay between each intelligent sound box and the intelligent sound box in the networking based on the first time stamp, the second time stamp, the third time stamp and the fourth time stamp in each feedback heartbeat signal.
Referring to fig. 2, fig. 2 is a specific flow chart of a volume adjusting method according to the present invention.
In this embodiment, when determining the clock delay between each intelligent speaker and the self, after the self enters the networking, the heartbeat signal is sent to each intelligent speaker in the networking, where the heartbeat signal includes a first timestamp when the self sends the heartbeat signal. After receiving the heartbeat signal, the other intelligent sound boxes generate feedback heartbeat signals, for example, the intelligent sound box receiving the heartbeat signal can directly add a second time stamp when receiving the heartbeat signal in the heartbeat signal, so that the heartbeat signal comprising the second time stamp is used as the feedback heartbeat signal, a third time stamp when sending the feedback heartbeat signal is added to the feedback heartbeat signal, and the feedback heartbeat signal comprising the first time stamp, the second time stamp and the third time stamp is sent to the intelligent sound box sending the heartbeat signal in a feedback manner.
After the self sends the heartbeat signal and receives the feedback heartbeat signal, a fourth time stamp when the feedback heartbeat signal is received is added in the feedback heartbeat signal, based on the fourth time stamp, clock delay between the self and the intelligent sound box sending the feedback heartbeat signal can be determined through each time stamp in the feedback heartbeat signal, and transmission delay between the self and the intelligent sound box sending the feedback heartbeat signal can be determined, so that first volume adjusting time of the self and second volume adjusting time of other intelligent sound boxes can be calculated.
After calculating the clock delay and the transmission delay between the intelligent sound box and other intelligent sound boxes, the clock delay and the transmission delay corresponding to each intelligent sound box are sent to the corresponding intelligent sound box, so that the second volume adjusting time of other intelligent sound boxes can be calculated no matter which intelligent sound box is sent by a user.
In addition, in this embodiment, the heartbeat signal may be sent to each other intelligent sound box by the intelligent sound box that enters the networking. If the feedback heartbeat signal is not received after the heartbeat signal is transmitted, the heartbeat signal is retransmitted, and the first time stamp is updated until the feedback heartbeat signal is received or the heartbeat signals transmitted by other intelligent sound boxes are received.
As a preferred embodiment, determining a clock delay between each smart speaker in the network and itself based on the first timestamp, the second timestamp, the third timestamp, and the fourth timestamp in each feedback heartbeat signal includes:

The third formula is:
Tdn=((T2n-T1n)+(T3n-T4n))/2;
Wherein, T dn is clock delay of the nth intelligent sound box, T 1n is a first time stamp when the heartbeat signal is sent to the nth intelligent sound box, T 2n is a second time stamp in the feedback heartbeat signal sent by the nth intelligent sound box, T 3n is a third time stamp in the feedback heartbeat signal sent by the nth intelligent sound box, T 4n is a fourth time stamp when the feedback heartbeat signal sent by the nth intelligent sound box is received, and n is a positive integer greater than 1 but not greater than the total number of intelligent sound boxes in the network.
In this embodiment, when calculating the clock delay between the respective intelligent speakers, subtracting the first time stamp from the second time stamp is the time when the nth intelligent speaker receives the heartbeat signal later than the time when the respective intelligent speaker sends the heartbeat signal, and subtracting the fourth time stamp from the third time stamp is the time when the respective intelligent speaker receives the feedback heartbeat signal later than the time when the nth intelligent speaker sends the feedback heartbeat signal, the sum of the two is divided by 2, so that the clock delay between the nth intelligent speaker and the respective intelligent speaker can be determined, so that the second volume adjustment time is calculated later, and the respective intelligent speakers can adjust the volume simultaneously.
It should be noted that the present application is not limited to the method of calculating the clock delay between itself and each smart speaker.
As a preferred embodiment, determining a transmission delay between each smart speaker in the network and itself based on the first timestamp, the second timestamp, the third timestamp, and the fourth timestamp in each feedback heartbeat signal includes:
determining the transmission delay between each intelligent sound box in the networking and the intelligent sound box according to a fourth formula based on the first timestamp, the second timestamp, the third timestamp and the fourth timestamp in each feedback heartbeat signal;
the fourth formula is:
Ttn=((T4n-T1n)-(T3n-T2n))/2;
Wherein, T tn is the transmission delay of the nth intelligent sound box, T 1n is the first time stamp when the heartbeat signal is sent to the nth intelligent sound box, T 2n is the second time stamp in the feedback heartbeat signal sent by the nth intelligent sound box, T 3n is the third time stamp in the feedback heartbeat signal sent by the nth intelligent sound box, T 4n is the fourth time stamp when the feedback heartbeat signal sent by the nth intelligent sound box is received, and n is a positive integer greater than 1 but not greater than the total number of intelligent sound boxes in the network.
In this embodiment, when the fourth formula is based, the time of transmitting signals to and from the nth intelligent sound box once can be calculated by subtracting the difference value of the first time stamp from the fourth time stamp and subtracting the difference value of the second time stamp from the third time stamp, and then divided by 2, so that the transmission delay when the nth intelligent sound box transmits signals to itself or the transmission delay when the nth intelligent sound box transmits signals to itself can be calculated, and the transmission delay can be calculated together when the second volume adjustment time is calculated later, so that the volume adjustment of each intelligent sound box can be ensured at the same time.
As a preferred embodiment, the volume adjustment instruction includes a volume adjustment target value and a volume adjustment step size.
The volume adjustment instruction in this embodiment includes a volume adjustment target value and a volume adjustment step length, and when each intelligent sound box adjusts its own volume, the volume adjustment can be performed according to the volume adjustment step length until the volume of itself is adjusted to the volume adjustment target value, so as to avoid causing obvious volume change when directly adjusting its own volume to the volume adjustment target value, and provide bad experience for users.
Based on this, when the volume adjustment command and the second volume adjustment time corresponding to the volume adjustment command are sent to each intelligent sound box by the intelligent sound box, the digital signal can be sent, but not limited to, the digital signal can be analyzed by the intelligent sound box according to the order of the volume adjustment command, the second volume adjustment time, the volume adjustment target value and the volume adjustment step length.
