As shown in fig. 2, the wireless speaker assembly includes a wireless speaker 101a, a wireless speaker 101 b. The second positioning module 1001 mainly obtains the distance or the mutual position relationship between the smart device 100 and each wireless speaker, and based on the second positioning module 1001, it may determine that a group of wireless speakers in the wireless loudspeaker closest to the smart device 100 is the wireless speaker 101a. The second processor 1002 switches the wireless speaker playing the audio signal to the wireless speaker 101a closest to the smart device 100 according to the distance between the smart device 100 and each wireless speaker acquired by the second positioning module 1001. In some embodiments, in the case that the wireless speaker currently playing the audio signal is the closest wireless speaker to the smart device 100, the smart device 100 may send an instruction not to switch to the wireless speaker playing the audio signal through the second wireless communication module 1003. In some embodiments, in the case that the wireless speaker currently playing the audio signal is the wireless speaker closest to the smart device 100, the smart device 100 may not send the switching instruction to the wireless speaker playing the audio signal, and still continue to play the audio signal. In some embodiments, the smart device includes a wearable device, a cell phone, a laptop, etc., wherein the wearable device may be a smart watch or a bracelet, etc. The wearable device is often together with the user, and the wireless speaker is switched according to the distance between the wearable device and the wireless speaker or the mutual position relation, so that the wireless speaker for playing the audio signal is automatically switched to the wireless speaker closest to the intelligent device 100, and the user experience is improved.
In some embodiments, the second processor 1002 may include a general-purpose processor or a special-purpose processor dedicated to a particular process, one or more programmable circuits, one or more dedicated circuits, or a combination thereof. For example, the second processor 1002 may be any one or a combination of a Micro Processing Unit (MPU), an SOC (system on chip), a DSP (digital processing).

In some embodiments, the second positioning module 1001 comprises a UWB positioning module. In some embodiments, the positions of the wireless speakers in the set of wireless speakers are known, and the UWB positioning module in the smart device 100 may be utilized to directly position the wireless speakers, so as to obtain the distance or mutual position relationship between the smart device 100 and the wireless speakers. In other embodiments, the wireless speaker is an audio device with wireless function, and may include a positioning module, a wireless communication module, a processor, and the like, and the positioning module may further include a UWB positioning module, and the UWB positioning module of the smart device 100 and the UWB positioning module of the wireless speaker may be used to cooperate with each other to obtain the distance or the mutual position relationship between the smart device 100 and each wireless speaker.
In some embodiments, the smart device 100 communicates with the wireless speaker through any one of bluetooth low energy, BLE mesh or UWB, and sends a switching instruction to the wireless speaker playing the audio signal or the wireless speaker to be switched to through any one of bluetooth low energy, BLE mesh or UWB. Fig. 3 shows a schematic diagram of a smart device controlling wireless speaker switching according to an embodiment of the present disclosure. In some embodiments, as shown in fig. 3, the second wireless communication module 1003 employs any one of bluetooth, bluetooth low energy, BLE mesh and UWB communication modes to perform wireless communication with each wireless speaker, for example, to transmit various switching instructions and/or parameters and the like from the second processor 1002 to the corresponding wireless speaker to control switching of the wireless speaker for playing audio signals. At present, the wireless speaker 101b is playing an audio signal, but since the relative position of the smart device 100 is changed, the wireless speaker closest to the smart device 100 is determined to be the wireless speaker 101a through the judgment of the second positioning module 1001, and at this time, the wireless speaker 101b playing the audio signal needs to be switched to the wireless speaker 101a.
In some embodiments, the second processor 1002 is further configured to determine a closest wireless speaker to the smart device 100; determining whether the wireless speaker playing the audio signal is the closest wireless speaker to the smart device 100; in a case where the wireless speaker that is playing the audio signal is not the wireless speaker closest to the smart device 100, determining the wireless speaker closest to the smart device 100 as the wireless speaker to be switched to; the first switching instruction is sent to the wireless speaker 101b which is playing the audio signal so as to transmit the playing parameter to the wireless speaker 101a to be switched to, or the playing parameter is received from the wireless speaker 101b which is playing the audio signal to be forwarded to the wireless speaker 101a to be switched to. The second processor 1002 is further configured to send a second switching instruction to the wireless speaker 101a to be switched to cause the wireless speaker 101a to be switched to process the audio signal based on the received playback parameter. In some embodiments, the playback parameters include the source of the audio signal being played, the progress of playing the audio signal, and the volume at which the audio signal is played. The progress of playing the audio signal includes a time offset of the progress of currently playing the audio signal relative to an initial time of the progress (for example, how long a song is played), and the sources of the played audio signal include the WIFI AP and the smart device 100. In some embodiments, when the played audio signal is from the WIFI AP, the information related to the WIFI AP may include at least one of an address of the WIFI AP, an address of a server where the audio signal is located, and a file where the audio signal is located. In some embodiments, when the played audio signal is from the smart device, the information related to the smart device may include at least one of a WIFI address of the smart device, a directory name where the audio signal is located, and a file name where the audio signal is located. The following embodiments will be described in detail by taking an example in which the wireless speaker 101a to be switched acquires audio signals from the WIFI AP and the smart device 100, respectively.
In some embodiments, the first switching instruction also indicates that the wireless speaker 101b playing the audio signal is ready to exit the play state, and the second switching instruction also indicates that the wireless speaker 101a to switch to is ready to enter the play state.
In some embodiments, the wireless speaker may be connected to the WIFI AP through the WIFI module, and then obtain an audio signal from the WIFI AP, where the audio signal may be audio, broadcast, and the like. Fig. 4 shows a schematic flowchart of acquiring an audio signal from a WIFI AP by a wireless speaker according to an embodiment of the present disclosure. As shown in fig. 4, the wireless speaker 101a to be switched to acquire an audio signal from the WIFI AP starts in step S301, and the wireless speaker 101b playing the audio signal receives a first switching instruction indicating that the wireless speaker 101b playing the audio signal is ready to exit the playing state. In some cases, the first switching instruction may come from the smart device 100, the wireless speaker 101b playing the audio signal that received the first switching instruction transmits the playback parameters to the wireless speaker 101a to be switched to, or the wireless speaker 101b playing the audio signal that received the first switching instruction transmits the playback parameters to the smart device 100, and the smart device 100 forwards the playback parameters received from the wireless speaker 101b playing the audio signal to the wireless speaker 101a to be switched to.
In step S302, the wireless speaker 101a to be switched to receives a second switching instruction indicating that the wireless speaker 101a to be switched to is ready to enter the playback state. In some embodiments, the second switching instruction may come from the smart device 100, at which time the smart device 100 forwards the playing parameters received from the wireless speaker 101b playing the audio signal to the wireless speaker 101a to be switched to by any one of bluetooth, bluetooth low energy, BLE mesh or UWB. In other embodiments, the second switching instruction may also be from the wireless speaker 101b playing the audio signal, in this case, the wireless speaker 101b playing the audio signal is connected to the wireless speaker 101a to be switched to through BLE mesh, and the wireless speaker 101b playing the audio signal sends the playing parameter to the wireless speaker 101a to be switched to through BLE mesh, where the playing parameter may be at least one of a source of the audio signal playing, a progress of playing the audio signal, and a volume of playing the audio signal. The transmission of playing parameters such as the progress of playing the audio signal enables the wireless loudspeaker 101a to be switched to only receive the required audio signal, thereby effectively avoiding the wireless loudspeaker from receiving some audio signals which are not to be played, and being beneficial to improving the experience of users. In this step S302, the timing at which the wireless speaker 101a to be switched receives the second switching instruction may be the same timing as or close to the timing at which the wireless speaker 101b that is playing an audio signal receives the first switching instruction.
In some embodiments, the second switching instruction is from the smart device 100 or the wireless speaker 101b playing the audio signal, the second switching instruction further indicating content after a first predetermined period of time of progress of the wireless speaker 101a to switch to receiving the audio signal. In some embodiments, the second switching instruction may be implemented by one radio frame, or may be implemented by a plurality of radio frames based on a plurality of communications.
In step S303, the wireless speaker 101a to be switched to receives the content after the first predetermined period of time of the schedule of the audio signal from the WIFI AP. At this time, the wireless speaker 101a to be switched receives the audio signal to be played after the first predetermined time period (the first predetermined time period may be within several tens or hundreds of milliseconds) of the currently played content from the WIFI AP according to the playing parameters. In order to make the audio playing continuously and reliably not jammed, the wireless speaker 101a to be switched to may receive the audio signal for a period of time and temporarily store the audio signal in the memory before starting playing, so that when the audio signal is temporarily interrupted due to the transient deterioration of the channel, the audio signal may be read from the memory to play, so that the audio signal is played without jamming, which is beneficial to improving the user experience. Therefore, the content after the first predetermined time period of the schedule for the wireless speaker 101a to be switched to receive the audio signal from the WIFI AP avoids receiving an audio signal that is not used, so that the switching is faster and the wireless channel is not wasted.
In step S304, the wireless speaker 101a to be switched to performs the play state after receiving the audio content for the second predetermined period of time. In some embodiments, the second switching instruction is from the smart device 100, and may also be from the wireless speaker 101b playing the audio signal, and the second switching instruction further instructs the wireless speaker 101a to be switched to execute the playing state after receiving the audio content for the second predetermined time period. When the audio signal received by the wireless speaker 101a to be switched exceeds a second predetermined period of time (the second predetermined period of time may be within several tens or several hundreds of milliseconds), the wireless speaker 101b that is playing the audio signal and the wireless speaker 101a to be switched perform playback switching.
In some embodiments, the first switching instruction also indicates the wireless speaker 101b that is playing the audio signal to fade out to play, and the second switching instruction also indicates the wireless speaker 101a to switch to fade in to play. Fade-in playback and fade-out playback make switching of audio signal playback more natural, and make the time synchronization precision of the wireless speaker 101b playing the audio signal and the wireless speaker 101a to be switched to be reduced, improve the user experience.
In some embodiments, each wireless speaker may communicate with the smart device 100 through any one of bluetooth, bluetooth low energy, LE audio, WIFI, and UWB, and the wireless speaker to be switched is determined according to a distance or a mutual position relationship between the smart device 100 and each wireless speaker, so that the wireless speaker to be switched receives an audio signal from the smart device 100 and plays the audio signal. Fig. 5 shows a schematic flow diagram of a wireless speaker acquiring an audio signal from a smart device according to an embodiment of the present disclosure. As shown in fig. 5, the wireless speaker acquires the audio signal from the smart device, and starts in step S401, the wireless speaker 101b playing the audio signal receives a first switching instruction indicating that the wireless speaker 101b playing the audio signal is ready to exit the playing state. In some cases, the first switching instruction may come from the smart device 100.
In step S402, the wireless speaker 101a to be switched to receives a second switching instruction indicating that the wireless speaker 101a to be switched to is ready to enter the playback state. In some embodiments, the second switching instruction may come from the smart device 100 and may also come from the wireless speaker 101b playing the audio signal, so that the wireless speaker 101a to be switched acquires the audio signal from the smart device 100 and plays the audio signal based on the received playing parameter, where the playing parameter may be at least one of a source of the played audio signal, a progress of playing the audio signal, and a volume of playing the audio signal. The transmission of playing parameters such as the progress of playing the audio signal enables the wireless loudspeaker 101a to be switched to only receive the required audio signal, thereby effectively avoiding the wireless loudspeaker from receiving some audio signals which are not to be played, and being beneficial to improving the experience of the user.
In step S403, the wireless speaker 101a to be switched to receives the content after the first predetermined period of time of the progress of the audio signal from the smart device 100. In some embodiments, the wireless speaker 101a to be switched to needs to receive the audio content after the first predetermined time period exceeding the progress of the audio signal and temporarily store the audio content in the memory, so as to start playing and switching, which can ensure that when the audio signal is temporarily interrupted due to instantaneous deterioration of the channel, the audio signal can be read from the memory to be played, so that the playing of the audio signal is not paused, which is beneficial to improving user experience. Meanwhile, the transmission of the playing parameters can avoid receiving unused audio signals, so that the switching is quicker, and meanwhile, the wireless channel is not wasted.
In step S404, the wireless speaker 101a to be switched to performs the play state after receiving the audio content for the second predetermined period of time.
The smart device 100 may enable information interaction with the wireless speaker 101b playing the audio signal and the wireless speaker 101a to be switched to via various wireless communication means. For example, the smart device 100 may transmit the switching instruction and/or the related data to the related wireless speakers respectively in a time-sharing manner.
In some embodiments, the smart device 100 may enable synchronized interaction with certain information (e.g., switching instructions) with the wireless speaker 101b playing the audio signal and the wireless speaker 101a to be switched to, as desired, via a bluetooth mode, a WIFI mode, or the like. In the bluetooth mode, the smart device 100 may establish a bluetooth link with one wireless speaker (for example, but not limited to, the wireless speaker 101 b), and the wireless speaker transmits related communication parameters of the bluetooth link to another wireless speaker (for example, but not limited to, the wireless speaker 101 a) through various wireless communication methods (for example, but not limited to, the UWB mode, the WIFI mode, etc.), so that the other wireless speaker may masquerade as the former to implement interception of the established bluetooth link, so that information transmitted by the smart device 100 via the bluetooth link may be received by each wireless speaker.
As shown in fig. 6, during the first sub-period, the smart device 100 may send a first switching instruction to the wireless speaker 101b playing the audio signal and send a second switching instruction to the wireless speaker 101a to be switched to. In some embodiments, the smart device 100 may send the first and second switching instructions within the first sub-period and encode the identity of the recipient within each switching instruction, whereby each wireless speaker may identify the wireless speaker 101b playing the audio signal and the wireless speaker 101a to switch to using the established bluetooth link and the listening to the bluetooth link. In the second sub-period, after the wireless speaker 101b playing the audio signal receives the first switching instruction, the playing parameter is output to the wireless speaker 101a to be switched to. During the third sub-period, the wireless speaker 101a to be switched to acquires the audio signal from the smart device 100 according to the received playing parameter. The wireless speaker 101a to be switched to may also temporarily store the audio signal received from the smart device 100 in the memory and then start playing, so that when the audio signal is temporarily interrupted due to transient channel degradation, the audio signal may be read from the memory and played, so that the playing of the audio signal is not jammed, which is beneficial to improving the user experience. In addition, wireless speaker 101b and/or wireless speaker 101a may also send an acknowledgement packet to smart device 100. In some embodiments, as shown in fig. 6, an acknowledgement/negative acknowledgement packet (ACK/NACK acknowledgement packet) is transmitted by the wireless speaker 101a to the smart device 100, and the transmission and reception of the acknowledgement packet may be completed in the front part of the period of the second bluetooth frame.
In addition to listening to the bluetooth link, the smart device 100 may also transmit a switching command and/or related data to a set of wireless speakers in a broadcast manner, which is not limited by this disclosure. Various implementation details in the above embodiments described based on bluetooth link may be incorporated herein, including but not limited to encoding the identification of the receiving party in the switching instruction, presetting corresponding first, second and third sub-periods within each period to implement the transmission of the switching instruction, the transmission of the playing parameters, and the transmission of the audio data, respectively.
In some embodiments, separate Bluetooth Low Energy (BLE), BLE mesh, etc. connections may be established between the smart device and the wireless speakers. In some embodiments, a Bluetooth Low Energy (BLE), BLE mesh, or the like may establish BLE or BLE mesh connections between the various wireless speakers.

In some embodiments, as shown in fig. 7, the smart device 100 further includes a vital sign measurement module 1004 configured to measure at least one vital sign of the heartbeat or pulse of the user. In some embodiments, the second processor 1002 is further configured to determine whether the smart device 100 is in a worn state based on the vital signs measured by the vital sign measurement module 1004; and under the condition that the intelligent device 100 is not in a wearing state, switching of the wireless speakers is forbidden, so that switching of the wireless speakers playing the audio signals is realized according to the distance or mutual position relation between the intelligent device 100 and different wireless speakers only when a user wears the intelligent device 100, and power consumption of the intelligent device 100 is reduced.
In some embodiments, an intelligent system is also provided, the intelligent system comprising a wireless speaker assembly and an intelligent device 100.
