Description

Wireless communication method for earphone and intelligent devices and wireless earphone assembly

Technical Field

The present disclosure relates to the field of headsets, and more particularly, to a wireless communication method and wireless headset assembly for an earphone and a plurality of smart devices.

Background

With the social progress and the improvement of the living standard of people, the earphone becomes an indispensable living article for people. Traditional wired headsets are connected to smart devices (e.g., smartphones, laptops, tablets, etc.) via wires, which, however, can limit the wearer's mobility, especially in sports scenarios. At the same time, the twisting and pulling of the earphone cord and the stethoscope effect all affect the listening experience of the earphone wearer. Although the common Bluetooth headset cancels a wire between the headset and the intelligent device, a wire still exists between the left ear and the right ear. Therefore, true wireless stereo earphones are produced.

The existing true wireless earphone (true wireless audio device) can only establish wireless link with one intelligent device and can only transmit audio data with the one intelligent device. However, when the wireless headset needs to receive audio data from a plurality of different smart devices, the existing wireless link can only be disconnected and the wireless link with another smart device can be re-established to receive audio data from another smart device. This undoubtedly increases the waste of communication resources and makes the operation of the user excessively cumbersome. Meanwhile, when the distance between the smart device and the wireless headset is long, communication quality and data transmission may be severely interfered. Obviously, the existing earphones can not provide a technical solution to the above problems.

Disclosure of Invention

The present disclosure is provided to solve the above-mentioned problems occurring in the prior art.

The scheme for carrying out wireless communication between the earphone and the intelligent devices can realize seamless switching of the Bluetooth links between the wireless earphone and the intelligent devices through establishing the Bluetooth links between the wireless earphone and the intelligent devices, audio data are transmitted without establishing the Bluetooth links repeatedly with the intelligent devices, unnecessary waste of communication resources is avoided, and when part of intelligent devices are far away from the wireless earphone, the communication quality between the part of intelligent devices and the wireless earphone is improved by taking a specific intelligent device as a relay device, so that the use experience of a user is improved.

According to a first aspect of the present disclosure, a method of wireless communication of an earset with a number of smart devices is provided. The pair of ear bud headphones include a first headphone and a second headphone, the plurality of smart devices include a first smart device and a second smart device, and the first headphone and the second headphone communicate via a wireless link. The wireless communication method includes: establishing, by one of the first and second headsets as a first master headset, a first bluetooth link with the first smart device, transmitting relevant communication parameters of the first bluetooth link to the other headset via the wireless link so that the other headset listens to the first bluetooth link as a first slave headset; establishing, by one of the first and second headsets as a second master headset, a second bluetooth link with the second smart device, transmitting the relevant communication parameters of the second bluetooth link to the other headset via the wireless link so that the other headset listens to the second bluetooth link as a second slave headset; performing, by the headphones, during a first time period of each bluetooth frame, communication with the first smart device via the first bluetooth link and its listening bluetooth link; communicating, by the first headset and the second headset, with each other via the wireless link during a second time period of each Bluetooth frame; performing, by the headphones, communication with the second smart device via the second Bluetooth link and its listening Bluetooth link during a third time period of each Bluetooth frame, wherein the first, second and third time periods are separate from each other.

According to the wireless communication method of the earphone and the intelligent devices, the Bluetooth links between the wireless earphone and the intelligent devices can be established, seamless switching of the Bluetooth links between the wireless earphone and the intelligent devices can be achieved, and the wireless communication method does not need to repeat establishment of the Bluetooth links with the intelligent devices to transmit audio data. The establishment of a bluetooth link often requires significant computing and communication resources, which take on the order of seconds or hundreds of milliseconds; therefore, the seamless switching of the Bluetooth links between the earphone and the intelligent devices avoids unnecessary waste of communication resources, reduces the waiting time of the user, and enables the user to establish communication links with the intelligent devices in a time-sharing manner, such as simultaneously receiving music played by the intelligent devices. In addition, when part of the intelligent devices are far away from the wireless earphone, the specific intelligent device serves as a relay device to improve the communication quality between the part of the intelligent devices and the wireless earphone, and therefore the use experience of a user is improved.

According to a second aspect of the present disclosure, a wireless headset assembly is provided. The wireless headset assembly is configured to communicate with a plurality of smart devices, the wireless headset assembly including an anti-ear headset including a first headset and a second headset, the plurality of smart devices including a first smart device and a second smart device. The first and second headsets include first and second bluetooth modules, respectively, each of the first and second bluetooth modules configured to: establishing a first Bluetooth link with the first smart device with the respective headset as a first master headset, transmitting relevant communication parameters of the first Bluetooth link to another headset via a wireless link; establishing a second bluetooth link with the second smart device with the respective headset as a second master headset, transmitting related communication parameters of the second bluetooth link to another headset via the wireless link; listening to the first Bluetooth link with the respective headset as a first slave headset; and listening to the second bluetooth link if the respective headset is acting as a second slave headset. The first and second bluetooth modules are further configured to: performing communication with the first smart device via the first bluetooth link and its listening bluetooth link, respectively, during a first time period of each bluetooth frame; communicating with each other via a wireless link during a second time period of the respective Bluetooth frames; and performing communication with the second smart device via the second bluetooth link and its listening bluetooth link, respectively, during a third time period of the respective bluetooth frames, wherein the first, second and third time periods are separate from each other.

The wireless earphone component

By establishing each Bluetooth link between the wireless earphone and a plurality of different intelligent devices, seamless switching of the Bluetooth links between the wireless earphone and the different intelligent devices can be realized, and audio data can be transmitted without repeating establishment of the Bluetooth links with the intelligent devices. The establishment of a bluetooth link often requires significant computational and communication resources, which take on the order of seconds or hundreds of milliseconds; therefore, the seamless switching of the Bluetooth links between the earphone and the intelligent devices avoids unnecessary waste of communication resources, reduces the waiting time of the user, and enables the user to establish communication links with the intelligent devices in a time-sharing manner, such as receiving music played by the intelligent devices at the same time. In addition, when part of the intelligent devices are far away from the wireless earphone, the specific intelligent device serves as a relay device to improve the communication quality between the part of the intelligent devices and the wireless earphone, and therefore the use experience of a user is improved.

According to a third aspect of the present disclosure, there is provided a non-volatile computer storage medium disposed in a first earpiece and a second earpiece of a wireless earpiece assembly and storing computer executable instructions that, when executed by a processor, perform a method of wireless communication in accordance with various embodiments of the first aspect of the present disclosure.

Detailed Description

The following detailed description is provided to enable those skilled in the art to better understand the technical solutions of the present disclosure, with reference to the accompanying drawings and specific embodiments. Embodiments of the present disclosure are described in further detail below with reference to the figures and the detailed description, but the present disclosure is not limited thereto. The order in which the various steps described herein are described as examples should not be construed as a limitation if there is no requirement for a contextual relationship between each other, and one skilled in the art would know that sequential adjustments may be made without destroying the logical relationship between each other, rendering the overall process impractical.

A wireless communication scheme of an earphone to a plurality of smart devices according to an embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

Fig. 1a shows a flow diagram of bluetooth communication between earsets comprising a first earpiece and a second earpiece, and between the first earpiece and the second earpiece via a wireless link, and a plurality of smart devices comprising the first smart device and the second smart device, according to one embodiment of the disclosure. As shown in fig. 1a, one of the first earphone and the second earphone is taken as the current earphone.

In step 101a, for a bluetooth link of a current headset with a first smart device, determine if the current headset is a first master headset? The first master earphone is an earphone which establishes a first Bluetooth link with the first intelligent device. If so, the current headset establishes a first bluetooth link with the first smart device in step 102a, transmits the relevant communication parameters of the first bluetooth link to the other headset via the wireless link in step 103a, and listens to the first bluetooth link as a first slave headset in step 104 a. If not, in step 105a, the other earphone is used as the first master earphone, the other earphone establishes a first bluetooth link with the first smart device, in step 106a, the other earphone transmits the relevant communication parameters of the first bluetooth link to the current earphone via the wireless link, the current earphone receives the relevant parameters of the first bluetooth link, and in step 107a, the current earphone listens to the first bluetooth link as the first slave earphone.

Similarly and synchronously, in step 101b, for the bluetooth link of the current headset with the second smart device, determine if the current headset is the second master headset? The second master earphone is an earphone which establishes a second Bluetooth link with a second intelligent device. If yes, the current headset establishes a second bluetooth link with the second smart device in step 102b, transmits the related communication parameters of the second bluetooth link to the other headset via the wireless link in step 103b, and listens for the second bluetooth link as a second slave headset in step 104 b. If not, in step 105b, the other earphone is used as a second master earphone, the other earphone establishes a second bluetooth link with the second smart device, in step 106b, the other earphone transmits the communication parameters related to the second bluetooth link to the current earphone via the wireless link, the current earphone receives the parameters related to the second bluetooth link, and in step 107b, the current earphone listens to the second bluetooth link as a second slave earphone.

In some embodiments, after one of the earpieces establishes a first bluetooth link with the first smart device and the other earpiece listens for the first bluetooth link, and one of the earpieces establishes a second bluetooth link with the second smart device and the other earpiece listens for the second bluetooth link, during a first time period of each bluetooth frame, communication with the first smart device is performed by the earpieces via the first bluetooth link and its listening bluetooth link, during a second time period of each bluetooth frame, the first earpiece and the second earpiece communicate with each other via the wireless link, and during a third time period of each bluetooth frame, communication with the second smart device is performed by the earpieces via the second bluetooth link and its listening bluetooth link, wherein the first time period, the second time period, and the third time period are separate from each other. The timing for communicating the earpieces with the plurality of smart devices will be described in detail below.

Fig. 1b shows a schematic diagram of a bluetooth link between an earphone to the ear and between it and several smart devices according to one embodiment of the present disclosure. As shown in fig. 1b, the set of headphones comprises a first headphone 101 and a second headphone 102, the first headphone 101 and the second headphone 102 communicating via a wireless link 105. The plurality of smart devices comprises a first smart device 103 and a second smart device 104; the first smart device 103 includes at least one smart device, and the second smart device 104 includes at least one smart device. The smart device may be a variety of portable smart terminals including, but not limited to, cell phones, tablets, wearable devices, and the like.

As an example of establishing a bluetooth link between the headphones and between them and the plurality of smart devices shown in fig. 1a, in fig. 1b, the first headphone 101 (as the first master headphone) establishes a first bluetooth link 106 with the first smart device 103, and the first headphone 101 can transmit the relevant communication parameters of the first bluetooth link 106 to the second headphone 102 via the wireless link 105, so that the second headphone 102 (as the first slave headphone) listens to the first bluetooth link 106, i.e. the first listening bluetooth link 108, using the relevant communication parameters. The second earpiece 102 establishes a second bluetooth link 107 with the second smart device 104 and the second earpiece 102 can transmit the relevant communication parameters of the second bluetooth link 107 via the wireless link 105 to the first earpiece 101 so that the first earpiece 101 listens for the second bluetooth link 107, i.e. the second listening bluetooth link 109, using the relevant communication parameters.

In some embodiments, when the related communication parameters are transmitted between the first earphone 101 and the second earphone 102 via the wireless link 105 (for example, the first earphone 101 transmits the related communication parameters of the first bluetooth link 106 to the second earphone 102 via the wireless link 105, or the second earphone 102 transmits the related communication parameters of the second bluetooth link 107 to the first earphone 101 via the wireless link 105), the related communication parameters may be transmitted to the other earphone directly or via a relay device, wherein the relay device may be any one or a combination of a charging box, any one of the first smart device 103 or the second smart device 104, a wired circuit, and the like.

In some embodiments, the relevant communication parameters of the first bluetooth link 106 include, but are not limited to, a bluetooth link address of the first smart device 103, encryption parameter information of the bluetooth link, etc., such that the second headset 102 in the listening state does not need to perform pairing and establishment of the bluetooth link, but rather enables reception of audio signals transmitted by the first smart device 103 via the first bluetooth link 106 by listening. The relevant communication parameters of the second bluetooth link 107 include, but are not limited to, the bluetooth link address of the second smart device 104, the encryption parameter information of the bluetooth link, etc., so that the first headset 101 in the listening state does not need to perform pairing and establishment of the bluetooth link, but enables reception of the audio signal transmitted by the second smart device 104 via the second bluetooth link 107 by listening.

In some embodiments, the first earpiece 101 and the second earpiece 102 may be interchangeable.

After the bluetooth link is established, the first smart device 103 may send audio data (for example, audio data related to the user in a call state) to the first headset 101, and the second headset 102 may also receive the audio data sent by the first smart device 103 via the first listening bluetooth link 108, and in response to the first headset 101 and the second headset 102 receiving the audio data, it may send a transmission response packet, which may be ACK/NACK information, to the first smart device 103. Likewise, the second smart device 104 may also send audio data (e.g., related audio data of the user in a song listening state) to the second headset 102, the first headset 101 may also receive the audio data sent by the second smart device 104 via the second listening bluetooth link 109, and in response to the first headset 101 and the second headset 102 receiving the audio data, it may send a transmission acknowledgement packet, which may be ACK/NACK information, to the second smart device 104.

In some embodiments, the number of smart devices may further include a third smart device and an nth smart device, N being a positive integer. Fig. 1c shows a flow diagram of bluetooth communication between the earpieces and the plurality of smart devices according to another embodiment of the disclosure. Similarly and synchronously (with respect to steps 101a and 101 b), as shown in fig. 3, in step 101c, for the bluetooth link of the current headset with the third smart device, is it determined if the current headset is the third master headset? The third master earphone is an earphone which establishes a third Bluetooth link with a third intelligent device. If yes, in step 102c, the current headset establishes a third bluetooth link with a third smart device, in the subsequent step, the current headset transmits the related communication parameters of the third bluetooth link to another headset via the wireless link, and the another headset listens for the third bluetooth link as a third slave headset. If not, in step 105c, using another earphone as a third master earphone, and establishing a third bluetooth link between the another earphone and the third smart device, in the subsequent step, the another earphone transmits the related communication parameters of the third bluetooth link to the current earphone via the wireless link, the current earphone receives the related parameters of the third bluetooth link, and the current earphone is used as a third slave earphone to listen to the third bluetooth link. Similarly and synchronously, one of the headsets in the headset assembly may also establish a bluetooth connection with the nth smart device, the other headset listening for the corresponding bluetooth connection.

In some embodiments, after establishing a first bluetooth link with a first smart device and another headset listening to the first bluetooth link for one of the earpieces, establishing a second bluetooth link with a second smart device and another headset listening to the second bluetooth link for one of the earpieces, and establishing a third bluetooth link with a third smart device and another headset listening to the third bluetooth link (or the earpieces also establishing similar links with an nth smart device), communication with the first smart device is performed by the earpieces via the first bluetooth link and their listening to the bluetooth link for a first period of each bluetooth frame, communication with the second smart device is performed by the earpieces via the first bluetooth link and their listening to the bluetooth link for a second period of each bluetooth frame, the first and second earpieces communicate with each other via the wireless link for a second period of each bluetooth frame, communication is performed by the earpieces via the second bluetooth link and their listening to the bluetooth link for a third period of each bluetooth frame, and communication is performed by the earpieces via the third bluetooth link and their listening to the bluetooth link for a third period of each bluetooth frame, and the third period of each bluetooth link and the N + bluetooth link for a fourth period of each bluetooth frame, and the N + the earpieces perform communication with the third bluetooth link for a fourth period, and N + the bluetooth link for the N + the third period of each bluetooth link, and the N + the earsets of each other. The timing for communicating the earpieces with the plurality of smart devices will be described in detail below.

Fig. 1d shows a schematic diagram of a bluetooth link between the headphones and several smart devices according to another embodiment of the disclosure. As shown in fig. 1d, the plurality of smart devices further includes a third smart device 110 (and an nth smart device 113); the third smart device 110 includes at least one smart device (and the nth smart device 113 also includes at least one smart device).

As an example of establishing a bluetooth link between the headphones and the plurality of smart devices shown in fig. 1c, in fig. 1d, the first headphone 101 (acting as a third master headphone) establishes a third bluetooth link 111 with the third smart device 110, and the first headphone 101 can transmit the relevant communication parameters of the third bluetooth link 111 to the second headphone 102 via the wireless link 105, so that the second headphone 102 (acting as a third slave headphone) listens to the third bluetooth link 111, i.e. the third listening bluetooth link 112, using the relevant communication parameters. The second headset 102 (as an nth master headset) establishes an nth bluetooth link 114 with the nth smart device 113 and the second headset 102 may transmit the relevant communication parameters of the nth bluetooth link 114 to the first headset 101 via the wireless link 105 so that the first headset 101 (as an nth slave headset) listens to the nth bluetooth link 114, i.e. the nth listening bluetooth link 115, with the relevant communication parameters.

In some embodiments, the related communication parameters of the third bluetooth link 111 include, but are not limited to, a bluetooth link address of the third smart device 110, encryption parameter information of the bluetooth link, etc., such that the second earpiece 102 in the listening state does not need to perform pairing and establishment of the bluetooth link, but rather enables reception of the audio signal transmitted by the third smart device 110 via the third bluetooth link 110 by listening. The related communication parameters of the nth bluetooth link 114 include, but are not limited to, a bluetooth link address of the nth smart device 113, encryption parameter information of the bluetooth link, and the like, so that the first headset 101 in the listening state does not need to perform pairing and establishment of the bluetooth link, but enables reception of the audio signal transmitted by the nth smart device 113 via the nth bluetooth link 114 by listening.

After establishing the bluetooth link, in response to the first headset 101 and/or the second headset 102 receiving the audio data from the third smart device 110 (and the nth smart device 113), the first headset 101 and/or the second headset 102 may send a transmission acknowledgement packet, which may be ACK/NACK information, to the first smart device 103.

Fig. 2 shows a flow chart of a method of wireless communication of an earset with a number of smart devices according to an embodiment of the present disclosure. As shown in fig. 2, in step 201, a first bluetooth link 106 is established by the first headset 101 and the first smart device 103, and the related communication parameters of the first bluetooth link 106 are transmitted to the second headset 102 via the wireless link 105, so that the second headset 102 listens to the first bluetooth link 106. In step 202, a second bluetooth link 107 is established by the second headset 102 with the second smart device 104, and the related communication parameters of the second bluetooth link 107 are transmitted to the first headset 101 via the wireless link 105, so that the first headset 101 listens to the second bluetooth link 107. In step 203, during a first period of each bluetooth frame, communication is performed by the earphone via the first bluetooth link 106 and its listening bluetooth link (i.e. the first listening bluetooth link 108) with the first smart device 103, during a second period of each bluetooth frame, the first earphone 101 and the second earphone 102 communicate with each other via the wireless link 105, and during a third period of each bluetooth frame, communication is performed by the earphone via the second bluetooth link 107 and its listening bluetooth link (i.e. the second listening bluetooth link 109) with the second smart device 104.

In some embodiments, a third bluetooth link 111 is established by the first earpiece 101 with the third smart device 110, and communication parameters related to the third bluetooth link 111 are transmitted to the second earpiece 102 via the wireless link 105, so that the second earpiece 102 listens for the third bluetooth link 111. During the fourth time period of each bluetooth frame, communication with the third smart device 110 is performed by the headphones via the third bluetooth link 111 and its listening bluetooth link (i.e., the third listening bluetooth link 112).

In some embodiments, an nth bluetooth link 114 is established by the second earpiece 102 with the nth smart device 113, and the related communication parameters of the nth bluetooth link 114 are transmitted to the first earpiece 101 via the wireless link 105 so that the first earpiece 101 listens for the nth bluetooth link 114. During the (N + 1) th period of each bluetooth frame, communication is performed by the headphones with the nth smart device 113 via the nth bluetooth link 114 and its listening bluetooth link (i.e., the nth listening bluetooth link 115)

Through the communication configuration according to the embodiments of the present disclosure, bluetooth links between the earphone (the first earphone 101 and the second earphone 102) and the plurality of smart devices can be maintained together, and repeated establishment of the bluetooth links with the smart devices can be avoided, so that by allocating corresponding time slots for communication between the earphone and the first smart device, communication between the earphones, communication between the earphone and the second smart device, and communication between the earphone and the third smart device (communication between the earphone and the N-th smart device) in each bluetooth frame according to the embodiments of the present disclosure, time-sharing communication and seamless switching of the bluetooth links between the wireless earphone and the plurality of different smart devices can be achieved, communication resources can be saved while user experience can be improved, and audio data transmission between the earphone and the plurality of smart devices can be achieved in a more efficient manner.

Fig. 3 illustrates a timing diagram of a method of wireless communication of an earset with several smart devices according to an embodiment of the disclosure. In general, wireless communication may be performed in predetermined length periods of time, with transmission and reception of corresponding data occurring in respective predetermined periods of time. According to the bluetooth protocol, the time of one bluetooth slot is 625 microseconds; when the advanced audio distribution framework protocol (A2 DP) is adopted, one bluetooth frame occupies a plurality of slots; when the hands-free frame protocol (HFP) is employed, one bluetooth frame occupies one slot. In some embodiments, the fixed time interval (one bluetooth frame) for audio data transmission may be set to 12 bluetooth slots (7500 microseconds), i.e., one bluetooth frame of 7500 microseconds is set to receive audio data transmitted by the audio data source. In some embodiments, the audio data is continuous in the conversation state or in the listening state, and therefore 12 bluetooth slots are repeated every 7500 microseconds.

As shown in fig. 3, during a first time period 301 of a bluetooth frame, the first smart device 103 sends first audio data, for example, audio data in a call state, to the first earphone 101, and the second earphone 102 is in a listening state. The first earpiece 101 receives call related audio data via the first bluetooth link 106 and the second earpiece 102 receives call related audio data via the first listening bluetooth link 108. During the second period 302 of the bluetooth frame, the first headset 101 and the second headset 102 communicate with each other via the wireless link 105, and as described above, may transmit a transmission acknowledgement packet therebetween, which may be ACK/NACK information; or other synchronization information, indication information, etc. During the third time period 303 of the bluetooth frame, the second smart device 104 sends second audio data, for example, audio data in a song listening state, to the second earphone 102, and the first earphone 101 is in a listening state. The second earpiece 102 receives the listening to song related audio data via the second bluetooth link 107 and the first earpiece 101 receives the listening to song related audio data via the second listening bluetooth link 109. Therefore, communication between the earphone and the intelligent devices can be achieved, the communication occurs in independent communication time periods, and communication interference is avoided. In some embodiments, during the fourth time period 304 of the bluetooth frame, the third smart device 110 sends third audio data to the first earpiece 101, and the second earpiece 102 is in the listening state. The first earpiece 101 receives third audio data via the third bluetooth link 114 and the second earpiece 102 receives third audio data via the third listening bluetooth link 115. Similarly, during the (N + 1) th time period, the nth smart device communicates with the anti-ear headset.

In some embodiments, a plurality of sub bluetooth frames may be further included in each period of the bluetooth frame (e.g., the first period 301, the second period 302, the third period 303, and the fourth period 304), for example, the bluetooth frame includes K sub bluetooth frames, where K is a positive integer. In some embodiments, taking the first time period 301 as an example, in which audio data is sent by the first smart device 103 to the first headset 101 in a first sub-bluetooth frame, in which a transmission acknowledgement packet containing ACK/NACK information is sent by the first headset 101 to the first smart device 103 in a second sub-bluetooth frame. The first time period 301 includes a plurality of groups of sub bluetooth frames (e.g., a group consisting of a first sub bluetooth frame and a second sub bluetooth frame).

In some embodiments, a group of smart devices that establish a bluetooth link with an earset may only be able to determine that it is establishing a bluetooth link with the earset, and may not be able to determine whether there are other smart devices that also establish a bluetooth link with the earset. Therefore, when a certain group of smart devices performs data transmission with the earphone, another group of smart devices remains in a data transmission state without stopping data transmission; or when data transmission is carried out between the earphones, the two groups of intelligent devices are still in a data transmission state. Thus, in some embodiments, during the first time period 301, while the first and

second headsets

101, 102 are performing communication with the first smart device 103, the other smart devices remain transmitting signals without a response from either the first headset 101 or the second headset 102. When the first earpiece 101 and the second earpiece 102 communicate with each other during the second time period 302; all smart devices 104 keep sending signals without a response from the first earpiece 101 or the second earpiece 102. During the third time period 303, while the first and

second headsets

101, 102 are performing communication with the second smart device 104, the other smart devices remain transmitting signals without a response from either the first headset 101 or the second headset 102. When the fourth time period 304 and other time periods perform communication with corresponding smart devices, the situation is similar to that described above, and details are not described herein.

As described above, when the current smart device and the headphone perform data transmission, other smart devices remain in the data transmission state without stopping data transmission; or when data transmission is performed between the earphones, all the intelligent devices are in a data transmission state. This results in unnecessary waste of resources. In addition, when other smart devices transmit data, interference is also caused to communication between the current smart device performing data transmission and the headphones, which may affect data transmission (reception) between the current smart device and the headphones. Therefore, the plurality of smart devices are divided into a customized smart device capable of interpreting the non-bluetooth standard command transmitted by the headphones and a non-customized smart device incapable of interpreting the non-bluetooth standard command. And sending indication information to the customized intelligent device by the earphone, wherein the indication information comprises a communication time interval of the earphone and the non-customized intelligent device, so that the customized intelligent device determines that the earphone is communicating with the non-customized intelligent device in the communication time interval and cannot respond to the customized intelligent device, and the customized intelligent device does not send audio data to the earphone. Therefore, certain communication resources can be saved; and reduce communication interference and improve system performance.

In some embodiments, the start of the time slot of each bluetooth frame of the custom smart device is adjusted such that the start of the time slot of each bluetooth frame of the custom smart device is aligned with the start of the time slot of each bluetooth frame of the non-custom smart device. When the slot starts are not aligned, a period of time that is not aligned is wasted, which interferes with the communication of two bluetooth frames before and after simultaneously.

In some embodiments, the timing of the wireless link 105 may also be adjusted so that the start of frame of the wireless link 105 is aligned with the start of frame of the bluetooth link performing the communication. Typically, bluetooth connections are frequency hopped and hopped at 1600Hz, and a bluetooth signal sent by a smart device in one time slot will only interfere with communication between the earphones in that time slot. If the frame starting point of the wireless link 105 is not aligned with the frame starting point of the bluetooth link performing communication, the bluetooth signal sent by the intelligent device in one time slot interferes with the communication between the earphones in the front and back time slots, so that the possibility of interference of the communication is increased, and the possibility of collision between the frequency point where the bluetooth signal is sent by the intelligent device and the frequency point of the communication between the earphones (namely, the communication is on the same frequency point) is higher; when switching between different bluetooth links, one transmission timeslot and one reception timeslot are wasted, which is equivalent to wasting two timeslots in one bluetooth frame. In some embodiments, the frequency point for the customized smart device to transmit the bluetooth frame may be generated based on a frequency point other than the frequency point for the non-customized smart device to transmit the bluetooth frame.

For example, when the first headset 101 and the second headset 102 maintain communication with the first smart device 103 for the first time period 301, the first headset 101 knows the frequency f1 at which the first smart device 103 transmits audio data; the first earphone 101 and the second earphone 102 may skip the frequency point f1 and select a frequency point other than the frequency point f1 to transmit data when transmitting data to each other in the second period 302. At this time, f1 can be directly removed from the candidate frequency point and directly selected from other frequency points, or a frequency modulation increment is added to the frequency point f1, so that the frequency point f1 is avoided. In some embodiments, a frequency hopping table may be maintained based on the quality of the wireless link 105, the signal quality of the bluetooth link performing the communication at various frequency points; that is, when the communication quality of the wireless link 105 is good, any available frequency point can be selected; when the communication quality of the wireless link 105 is poor, a frequency point with good signal quality may be selected as a frequency point used in frequency hopping.

In some embodiments, when some smart devices (e.g., non-customized smart devices, or customized smart devices) are far away from the earphone, the communication quality between the smart devices and the earphone may be reduced, and at this time, a relay device of the customized smart device between the smart devices and the earphone may be selected, relay audio data from some smart devices (e.g., non-customized smart devices, or customized smart devices) may be received, and the relay audio data may be forwarded to the earphone when the earphone performs communication with the customized smart device.

In some embodiments, a first communication quality parameter between the earphone and the certain intelligent device (e.g. the off-the-shelf intelligent device, which may also be a customized intelligent device), a second communication quality parameter between the customized intelligent device to enable the relay function and the certain intelligent device (e.g. the off-the-shelf intelligent device, which may also be a customized intelligent device) are respectively determined; enabling the customized smart device to act as a relay device for communication between the headphones and the certain smart devices (e.g., an off-the-shelf smart device, which may also be a customized smart device) when the first communication parameter is less than a first threshold, or when the first communication parameter is less than the second communication quality parameter and exceeds a second threshold; and after the customized intelligent device successfully receives the relay audio data, transmitting a response packet to the non-customized intelligent device by the customized intelligent device. So, can promote the communication quality between earphone and the remote smart machine.

through establishing each bluetooth link between wireless earphone and the intelligent device of a plurality of differences, can realize wireless earphone and the seamless switching of the bluetooth link of a plurality of different intelligent devices, need not to transmit audio data with the establishment of each intelligent device repetition bluetooth link.
