Description

Technical Field

[0001] This invention relates to the field of headphone technology, and in particular to a true wireless stereo headphone, a headphone communication switching method, system, and medium. Background Technology

[0002] In existing True Wireless Stereo (TWS) solutions, the main earbud establishes a Bluetooth connection with the smart device and begins sending or receiving data in the time slots agreed upon by the Bluetooth protocol. The secondary earbud listens to the data communication between the main earbud and the smart device by receiving air signals, and switches and completes the communication between the main earbud and the secondary earbud during the intervals between the communication between the main earbud and the smart device, thus realizing the TWS earbud function.

[0003] However, with this TWS solution, when the amount of data sent from the smart device to the main ear is large and the remaining time slot is very short, it is sometimes not enough for the main and secondary earbuds to initiate and complete a communication. In this case, the communication between the main and secondary earbuds will affect the transmission and reception of the main link information of the original communication between the smart device and the main earbud, thereby increasing the number of retransmissions between the smart device and the main earbud. In severe cases, it will cause music stuttering, increase system power consumption, affect the connection stability of the entire system, and lead to a poor user experience. Summary of the Invention

[0004] Therefore, it is necessary to provide true wireless stereo headphones, headphone communication switching methods, systems, and media to solve the problem that communication between the primary and secondary earbuds will affect the main link information transmission and reception between the original smart device and the primary earbud.

[0005] A method for switching headphone communication is provided, applied to a communication system, the communication system including a smart device, a main earphone, and a secondary earphone, the method comprising:

[0006] After the start of a unit time slot, the main earphone initiates an RF connection with the smart device and the secondary earphone;

[0007] After the radio frequency connection is stabilized, the main earphone receives data from the smart device sent by the smart device based on the radio frequency connection;

[0008] After the main earphone finishes receiving the smart device data sent by the smart device, the main earphone calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization duration and the first transmit / receive duration; wherein, the RF stabilization duration indicates the duration from RF connection startup to stabilization, and the first transmit / receive duration indicates the duration of transmitting and receiving smart device data between the main earphone and the smart device;

[0009] If the remaining time slot duration is less than the preset time slot duration threshold, the main earphone remains locked at the frequency of the current radio frequency connection and receives feedback information sent by the secondary earphone.

[0010] After the main earphone finishes receiving the feedback information sent by the secondary earphone, the main earphone closes the radio frequency connection with the secondary earphone.

[0011] In one embodiment, the method further includes:

[0012] If the remaining time slot duration is greater than or equal to a preset time slot duration threshold, the main earphone shuts down the radio frequency connection with the secondary earphone.

[0013] During the agreed communication time of the main earphone within a unit time slot, the main earphone initiates the radio frequency connection with the secondary earphone.

[0014] After the RF connection is stabilized, the main earphone remains locked at the frequency of the current RF connection and receives feedback information sent by the secondary earphone.

[0015] After the main earphone finishes receiving the feedback information sent by the secondary earphone, the main earphone closes the radio frequency connection with the secondary earphone.

[0016] In one embodiment, the method further includes:

[0017] The main earphone acquires a second transmit / receive duration; wherein, the second transmit / receive duration indicates the duration of transmitting and receiving feedback information between the main earphone and the secondary earphone;

[0018] Calculate the sum between the second transmit / receive duration and the radio frequency stabilization duration, and use the sum between the sum and the preset shutdown duration as the time slot duration threshold.

[0019] In one embodiment, the main earphone calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization duration and the first transmit / receive duration, including:

[0020] The main earphone subtracts the radio frequency stabilization duration from the unit time slot duration and the first transmit / receive duration, and uses the calculated difference as the remaining time slot duration.

[0021] In one embodiment, the main earphone initiates an radio frequency connection with the secondary earphone, including:

[0022] The main earphone is configured with a target frequency of a phase-locked loop, and the current frequency of the phase-locked loop within the main earphone is adjusted.

[0023] The method further includes:

[0024] When the current frequency of the phase-locked loop in the main earphone is locked to the target frequency, the radio frequency connection is confirmed to be stable.

[0025] A method for switching headphone communication is provided, applied to a communication system, the communication system including a smart device, a main earphone, and a secondary earphone, the method comprising:

[0026] After the start of a unit time slot, the secondary earphone initiates an RF connection with the smart device and the primary earphone;

[0027] After the radio frequency connection is stabilized, the secondary earphone receives air signals based on the radio frequency connection to listen to the smart device data between the primary earphone and the smart device;

[0028] After the main earphone finishes receiving the smart device data sent by the smart device, the secondary earphone calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization duration and the first transmit / receive duration; wherein, the RF stabilization duration indicates the duration from RF connection startup to stabilization, and the first transmit / receive duration indicates the duration of transmitting and receiving smart device data between the main earphone and the smart device;

[0029] If the remaining time slot duration is less than the preset time slot duration threshold, the secondary earphone remains locked at the frequency point of the current radio frequency connection and sends feedback information to the primary earphone;

[0030] After the secondary earphone finishes sending feedback information to the primary earphone, the secondary earphone disconnects the radio frequency connection with the primary earphone.

[0031] In one embodiment, the method further includes:

[0032] If the remaining time slot duration is greater than or equal to a preset time slot duration threshold, the secondary earphone shuts down the radio frequency connection with the primary earphone.

[0033] During the agreed communication time of the secondary earpiece within a unit time slot, the secondary earpiece initiates an RF connection with the primary earpiece.

[0034] After the RF connection is stabilized, the secondary earphone remains locked at the frequency of the current RF connection and sends feedback information to the primary earphone.

[0035] After the secondary earphone finishes sending feedback information to the primary earphone, the secondary earphone disconnects the radio frequency connection with the primary earphone.

[0036] A communication system includes a smart device, a main earpiece, and a secondary earpiece, wherein the main earpiece establishes a radio frequency connection with the smart device;

[0037] The main earphone and the secondary earphone are used to initiate an RF connection after the start of a unit time slot;

[0039] The secondary earpiece is used to monitor smart device data between the primary earpiece and the smart device by receiving air signals.

[0040] The main earphone and the secondary earphone are further configured to calculate the remaining time slot duration within a unit time slot duration based on the RF stabilization duration and the first transmit / receive duration after the data transmission and reception between the main earphone and the smart device is completed; wherein, the RF stabilization duration indicates the duration from RF connection startup to stabilization, and the first transmit / receive duration indicates the duration of data transmission and reception between the main earphone and the smart device; if the remaining time slot duration is less than a preset time slot duration threshold, the frequency point of the RF connection between the main earphone and the secondary earphone is locked, and feedback information is transmitted and received; after the feedback information transmission and reception between the main earphone and the secondary earphone is completed, the RF connection is closed.

[0041] A computer-readable storage medium storing a program that, when executed by a processor, causes the processor to perform the steps of the above-described headphone communication switching method.

[0042] A true wireless stereo headset includes a memory and a processor. The memory stores a program, which, when executed by the processor, causes the processor to perform the steps of the headset communication switching method described above.

[0043] This invention provides true wireless stereo headphones, a headphone communication switching method, a system, and a medium. First, after the start of a unit time slot, the main earphone initiates an RF connection with the secondary earphone. Then, after the RF connection stabilizes, regular communication occurs between the main earphone and the smart device. Next, after the smart device completes data transmission and reception between the main earphone and the smart device, the main earphone calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization time and the first transmission / reception time. If the remaining time slot duration is less than a preset time slot duration threshold, the main earphone and the secondary earphone transmit and receive feedback information based on the stable RF connection. Finally, after the feedback information transmission and reception between the main earphone and the secondary earphone is completed, the RF connection is closed to allow the start of the next unit time slot. Therefore, this invention, by maintaining the RF connection, ensures that communication between the main and secondary earphones does not affect the main link information transmission and reception of the original communication between the smart device and the main earphone, even when the amount of data sent from the smart device to the main earphone is large and the remaining time slot interval is short. This effectively maintains communication stability and provides a good user experience. Attached Figure Description

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] like Figure 1 As shown, Figure 1 This is a flowchart illustrating the headphone communication switching method in the first embodiment, applied to a communication system including a smart device, a main earphone, and a secondary earphone. This embodiment aims to address situations in TWS communication where the smart device sends a large amount of data to the main earphone, and the remaining time slot interval is very short. This first embodiment takes the main earphone as the primary perspective of the communication switching method; the following will be combined with... Figure 2 The first timing diagram shown is used for illustration.

[0056] The steps provided by the headphone communication switching method in this first embodiment include:

[0057] Step 102: After the start of a unit time slot, the main earphone initiates the radio frequency connection between the smart device and the secondary earphone.

[0058] Specifically, corresponding Figure 2 After a unit time slot (slot N) begins, the main earpiece will activate its RF circuitry and establish RF connections with both the smart device and the secondary earpiece. This step corresponds to... Figure 2 The period during which the RF signal between the main and secondary earphones is turned on and waits for stabilization. Here, RF refers to radio frequency.

[0059] See Figure 3 , Figure 3 This is a schematic diagram of a radio frequency (RF) circuit, which includes a receiving and transmitting antenna 310, an RF receiving circuit 320, an RF transmitting circuit 330, and a phase-locked loop (PLL) 340. It can be installed in smart devices, main earphones, and secondary earphones. The complete data transmission and reception process within this RF circuit is as follows:

[0060] a. RF reception process: Configure PLL target frequency -> Turn on PLL -> Wait for PLL to stably lock onto the target frequency from 0 -> RF receiving circuit normally receives data and forwards it to subsequent circuits.

[0061] b. RF transmission process: Configure PLL target frequency -> Turn on PLL -> Wait for PLL to stably lock onto the target frequency from 0 -> RF transmission circuit transmits normally and subsequent circuits send RF data.

[0062] Of course, data transmission and reception are not involved in this step. For the main earphone, the target frequency of the phase-locked loop (PLL) is configured, and the current frequency of the PLL within the main earphone is adjusted. When the current frequency of the PLL within the main earphone is locked to the target frequency, the RF connection is confirmed to be stable.

[0063] Step 104: After the RF connection is stable, the main earphone receives data from the smart device sent by the smart device based on the RF connection.

[0064] After waiting for the stabilization time required by the main earphone's own RF circuitry, the main earphone begins receiving data from the smart device based on the established RF connection. This step corresponds to... Figure 2 The time period during which the "main earphone and smart device receive or send data via RF".

[0065] Step 106: After the main earpiece finishes receiving the data sent by the smart device, the main earpiece calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization duration and the first transmit / receive duration.

[0066] Among them, the RF stabilization time indicates the time it takes for the RF connection to stabilize from startup, which is... Figure 2 The duration of "RF activation and stabilization between the main and secondary earpieces". The first transmit / receive duration indicates the duration of data transmission and reception between the main earpiece and the smart device, which is... Figure 2 The duration of "data reception or transmission between the main headset and the smart device via RF".

[0067] Next, the remaining time slot duration is calculated as follows: the main earphone subtracts the RF stabilization duration from the unit time slot duration and subtracts the first transmit / receive duration, and the difference is taken as the remaining time slot duration. The remaining time slot duration is... Figure 2 The duration of "RF between the main and secondary earpieces remains on and data is received or transmitted" and "RF between the main and secondary earpieces is off".

[0068] Step 108: Determine whether the remaining time slot duration is less than the preset time slot duration threshold. If the remaining time slot duration is less than the preset time slot duration threshold, proceed to step 110, whereby the main earphone remains locked to the frequency of the current RF connection and receives feedback information sent by the secondary earphone.

[0069] The remaining time slot duration determines the subsequent communication method between the primary and secondary earbuds. When the remaining time slot duration is less than the preset time slot duration threshold, it indicates that the primary and secondary earbuds can communicate normally, and the communication time between the smart device and the primary earbud is very short. At this time, the PLL between the primary and secondary earbuds is kept locked at the target frequency to transmit and receive feedback information between the primary and secondary earbuds based on a stable RF connection. This reduces the time for RF channel reconfiguration and waiting for stabilization, effectively reducing conflicts and retransmissions in smart device data and TWS data transmission. This step corresponds to... Figure 2 The time period during which "RF between the main earphone and the secondary earphone remains on and receives or transmits data".

[0070] Here, the time slot duration threshold can be set to 200us, or it can be set to other values. The principles that must be followed when setting this value will be explained later.

[0071] Step 112: After the feedback information between the main earphone and the secondary earphone is transmitted and received, the main earphone shuts down the radio frequency connection between the main earphone and the secondary earphone.

[0072] In other words, the RF connection will be closed after data transmission between the primary and secondary earphones is complete. Therefore, the primary and secondary earphones need to reset the target frequency and re-establish the RF connection before the next data transmission and reception. This step corresponds to... Figure 2 The time period during which "RF is turned off between the main and secondary earphones".

[0073] As can be seen, the headphone communication switching method in the first embodiment above, by maintaining the radio frequency connection, can ensure that the communication between the main and secondary ears will not affect the main link information transmission and reception of the original communication between the smart device and the main headphone, even when the amount of data sent by the smart device to the main ear is large and the remaining time slot is very short. This effectively maintains communication stability and brings a good user experience.

[0074] like Figure 4 As shown, Figure 4 This is a flowchart illustrating the headphone communication switching method in the second embodiment, which is also applied to a communication system including a smart device, a main earphone, and a secondary earphone. This second embodiment also uses the main earphone as the primary perspective for the communication switching method. The following text will refer to... Figure 5 The second timing diagram shown will be used for illustration.

[0075] The steps provided by the headphone communication switching method in this second embodiment include:

[0076] Step 402: After the start of a unit time slot, the main earphone initiates the radio frequency connection between the smart device and the secondary earphone.

[0077] Step 404: After the RF connection is stable, the main earphone receives data from the smart device sent by the smart device based on the RF connection.

[0078] Step 406: After the main earpiece finishes receiving the data sent by the smart device, the main earpiece calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization duration and the first transmit / receive duration.

[0079] Step 408: Determine whether the remaining time slot duration is less than a preset time slot duration threshold. If the remaining time slot duration is less than the preset time slot duration threshold, proceed to step 410, where the primary earphone remains locked to the current RF connection frequency and receives feedback information sent by the secondary earphone. If the remaining time slot duration is greater than or equal to the preset time slot duration threshold, proceed to step 414.

[0080] Step 412: After the feedback information between the main earphone and the secondary earphone is transmitted and received, the main earphone shuts down the radio frequency connection between itself and the secondary earphone.

[0081] In a specific implementation scenario, steps 402-412 are basically the same as steps 102-112 of the headphone communication switching method in the first embodiment, and will not be described again here.

[0082] Step 414: The main earphone disconnects the RF connection between itself and the secondary earphone.

[0083] When the remaining time slot duration is greater than or equal to the preset time slot duration threshold, it indicates that there is sufficient remaining time and communication between the main and secondary earphones is not urgent. In this case, power consumption can be reduced by actively disabling the RF connection between the main and secondary earphones. This step corresponds to... Figure 5 The time period during which "RF is turned off between the main and secondary earphones".

[0084] In this invention, the time slot duration threshold is set as follows: the main earpiece acquires the second transmit / receive duration; wherein, the second transmit / receive duration indicates the duration of the transmit / receive feedback information between the main earpiece and the secondary earpiece, corresponding to... Figure 5 The duration of "data reception or transmission between the main and secondary earpieces via RF" is calculated. Then, the sum of the second transmit / receive duration and the RF stabilization duration is calculated, and this sum is combined with a preset shutdown duration as the time slot duration threshold; where the RF stabilization duration corresponds to... Figure 5 The duration of "RF switching between the main and secondary earpieces on and waiting for stabilization" refers to the preset shutdown duration, which is the time it takes for the RF to transition from "on" to "off," and is generally a very short time. It's understandable that the second transmit / receive duration, the RF stabilization duration, and the preset shutdown duration can all be obtained through experimental testing. When the time slot duration threshold is set to the sum of these three or slightly greater, the RF between the main and secondary earpieces can completely complete the process of "off state" → "on state" → "stabilized state" → "data transmission and reception" → "off state."

[0085] Step 416: During the agreed communication time of the main earphone within the unit time slot, the main earphone initiates the radio frequency connection between itself and the secondary earphone.

[0086] This means the main earphone re-activates its RF circuit to establish an RF connection with the secondary earphone, and then waits for the stabilization time required by the RF circuits of both the main and secondary earphones. This step corresponds to... Figure 5 The period during which the RF between the main and secondary earphones is turned on and waits for stabilization.

[0087] Step 418: After the RF connection is stable, the main earphone remains locked at the frequency of the current RF connection and receives feedback information sent by the secondary earphone.

[0088] This means that the PLL between the primary and secondary earbuds is kept locked at the target frequency, and the primary earbud receives TWS data sent by the secondary earbud. This step corresponds to... Figure 5 The time period during which the main earphone and the secondary earphone receive or transmit data via RF.

[0089] Step 420: After the feedback information between the main earphone and the secondary earphone is transmitted and received, the main earphone disconnects the radio frequency connection between itself and the secondary earphone.

[0090] In other words, the RF connection is closed after data transmission between the primary and secondary earphones is complete. This allows the primary and secondary earphones to reset their target frequency and re-establish the RF connection before the next data transmission and reception. This step corresponds to... Figure 5 The time period during which "RF is turned off between the main and secondary earphones".

[0091] As can be seen, the headphone communication switching method in the second embodiment described above can maintain normal communication even when the idle time slot between the smart device and the main headphone is very short, and can also minimize device power consumption when the idle time slot between the smart device and the main headphone is sufficient. This makes the TSW solution of the present invention have the advantages of high efficiency, low power consumption, low collision and low retransmission.

[0092] like Figure 6 As shown, Figure 6 This is a flowchart illustrating the headphone communication switching method in the third embodiment, applied to a communication system including a smart device, a main earphone, and a secondary earphone. This third embodiment focuses on the secondary earphone as the primary perspective of the communication switching method. The following text, in conjunction with... Figure 5 The timing diagram is used for illustration.

[0093] The steps provided by the headphone communication switching method in this third embodiment include:

[0094] Step 602: After the start of a unit time slot, the secondary earphone initiates the RF connection with the primary earphone.

[0095] Step 604: After the radio frequency connection is stable, the secondary earpiece listens to the smart device data between the primary earpiece and the smart device by receiving air signals.

[0096] Step 606: After the main earpiece finishes receiving the smart device data sent by the smart device, the secondary earpiece calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization duration and the first transmit / receive duration.

[0097] Step 608: Determine whether the remaining time slot duration is less than a preset time slot duration threshold. If the remaining time slot duration is less than the preset time slot duration threshold, proceed to step 610, whereby the secondary earphone remains locked to the current RF connection frequency and sends feedback information to the primary earphone. If the remaining time slot duration is greater than or equal to the preset time slot duration threshold, proceed to step 614.

[0098] Step 612: After the secondary earphone finishes sending feedback information to the primary earphone, the secondary earphone disconnects the radio frequency connection with the primary earphone.

[0099] Step 614: The secondary earphone disconnects the RF connection with the primary earphone.

[0100] Step 616: During the agreed communication time of the secondary earphone within the unit time slot, the secondary earphone initiates the radio frequency connection with the primary earphone.

[0101] Step 618: After the RF connection is stable, the secondary earphone remains locked at the frequency of the current RF connection and sends feedback information to the primary earphone.

[0102] Step 620: After the secondary earphone finishes sending feedback information to the primary earphone, the secondary earphone disconnects the radio frequency connection with the primary earphone.

[0103] In a specific implementation scenario, steps 602-620 above are essentially the same as steps 402-412 of the headphone communication switching method in the second embodiment. See also Figure 5 The main difference is that the secondary earpiece listens to the data between the main earpiece and the smart device by receiving air signals. When communicating between the main and secondary earpieces, the secondary earpiece sends TWS data and the main earpiece receives TWS data.

[0104] In one embodiment, such as Figure 7 As shown, a communication system is proposed, which includes a smart device 702, a main earpiece 704, and a secondary earpiece 706; wherein,

[0105] The main earphone 704 and the secondary earphone 706 are used to initiate the RF connection after the start of a unit time slot;

[0106] The main earphone 704 and the smart device 702 are used to transmit and receive data from the smart device 702 based on the RF connection after the RF connection is stable;

[0107] The secondary earpiece 706 is used to monitor data between the main earpiece 704 and the smart device 702 by receiving air signals;

[0108] The main earphone 704 and the secondary earphone 706 are also used to calculate the remaining time slot duration within a unit time slot duration based on the RF stabilization duration and the first transmit / receive duration after the main earphone 704 and the smart device 702 have completed data transmission and reception between the smart device 702 and the main earphone 704. The RF stabilization duration indicates the duration from RF connection startup to stabilization, and the first transmit / receive duration indicates the duration of data transmission and reception between the main earphone 704 and the smart device 702. If the remaining time slot duration is less than a preset time slot duration threshold, the frequency point of the RF connection between the main earphone 704 and the secondary earphone 706 is locked, and feedback information is transmitted and received. After the feedback information transmission and reception between the main earphone 704 and the secondary earphone 706 is completed, the RF connection is closed.

[0109] Figure 8An internal structural diagram of a true wireless stereo headset in one embodiment is shown. Figure 8 As shown, the true wireless stereo headset includes a processor, a memory, and an antenna connected via a system bus. The memory includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores an operating system and may also store a program. When executed by the processor, this program enables the processor to implement a headset communication switching method. The internal memory may also store a program, which, when executed by the processor, enables the processor to implement the headset communication switching method. Those skilled in the art will understand that… Figure 8 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the true wireless stereo headphones to which the present application is applied. Specific true wireless stereo headphones may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0110] A true wireless stereo headset includes a memory, a processor, and a program stored in the memory and executable on the processor. When the processor executes the program, it performs the following steps: after the start of a unit time slot, the main headset initiates an RF connection with a smart device and a secondary headset; after the RF connection stabilizes, the main headset receives smart device data sent by the smart device based on the RF connection; after the main headset finishes receiving the smart device data, the main headset calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization time and a first transmit / receive time. If the remaining time slot duration is less than a preset time slot duration threshold, the main headset remains locked at the frequency of the current RF connection and receives feedback information sent by the secondary headset; after the main headset finishes receiving the feedback information sent by the secondary headset, the main headset closes the RF connection with the secondary headset.

[0111] The system implements the following steps: After the start of a unit time slot, the secondary earpiece initiates an RF connection with the smart device and the primary earpiece; after the RF connection stabilizes, the secondary earpiece receives air signals based on the RF connection to monitor the smart device data between the primary earpiece and the smart device; after the primary earpiece finishes receiving the smart device data sent by the smart device, the secondary earpiece calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization time and the first transmit / receive time duration; if the remaining time slot duration is less than a preset time slot duration threshold, the secondary earpiece remains locked at the frequency point of the current RF connection and sends feedback information to the primary earpiece; after the secondary earpiece finishes sending feedback information to the primary earpiece, the secondary earpiece closes the RF connection with the primary earpiece.

[0112] A computer-readable storage medium storing a program that, when executed by a processor, performs the following steps:

[0113] After the start of a unit time slot, the main earpiece initiates the RF connection with the smart device and the secondary earpiece. After the RF connection stabilizes, the main earpiece receives data from the smart device based on the RF connection. After the main earpiece finishes receiving the data from the smart device, it calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization time and the first transmit / receive time. If the remaining time slot duration is less than a preset time slot duration threshold, the main earpiece remains locked at the frequency of the current RF connection and receives feedback information from the secondary earpiece. After the main earpiece finishes receiving the feedback information from the secondary earpiece, it closes the RF connection with the secondary earpiece.

[0114] The system implements the following steps: After the start of a unit time slot, the secondary earpiece initiates an RF connection with the smart device and the primary earpiece; after the RF connection stabilizes, the secondary earpiece receives air signals based on the RF connection to monitor the smart device data between the primary earpiece and the smart device; after the primary earpiece finishes receiving the smart device data sent by the smart device, the secondary earpiece calculates the remaining time slot duration within the unit time slot duration based on the RF stabilization time and the first transmit / receive time duration; if the remaining time slot duration is less than a preset time slot duration threshold, the secondary earpiece remains locked at the frequency point of the current RF connection and sends feedback information to the primary earpiece; after the secondary earpiece finishes sending feedback information to the primary earpiece, the secondary earpiece closes the RF connection with the primary earpiece.
