Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

Currently, most electronic devices, such as computers, mobile phones, music playing devices, etc., can play audio data. Along with further development of the technology level and increase of demands of users, the electronic device can be connected with the external audio playing device, so that the electronic device can play audio data through the external audio playing device. The audio playing device may include an earphone, a sound box, a vehicle-mounted device and the like. The audio playing device can receive the audio data transmitted by the electronic device and play the audio data. The electronic device can be connected with the audio playing device in a wired mode or a wireless mode.

When a user actually plays audio data transmitted by an electronic device using an audio playing device, the user often uses a headset in a wireless communication manner to play the audio data by using, for example, a headset that uses wireless fidelity (Wireless Fidelity, wiFi) communication or a headset that uses Bluetooth (BT) communication. Particularly for users with high demands, the playing of audio data is performed by means of real wireless stereo (True Wireless Stereo, TWS) headphones with a wireless separation of the left channel from the right channel. The real wireless stereo headset can realize the wireless separation of the real Bluetooth left channel and the real Bluetooth right channel, namely, the two headsets of the real wireless stereo headset do not need wired connection. When playing audio data by using the real wireless stereo headset, the electronic device may connect to a master headset of the wireless stereo headset, and the slave headset is connected to the master headset, where the master headset transmits link information (including, but not limited to, bluetooth address and other information) between the slave headset and the electronic device to the slave headset, so that the slave headset may acquire audio data of the electronic device (e.g., an audio source device) by means of bluetooth listening (snip), thereby directly acquiring audio data from the electronic device with the master headset, and in some manners, the master headset may also transmit the audio data to the slave headset after receiving the audio data transmitted by the electronic device by means of the master headset. Therefore, stereo playing with separated left and right sound channels is realized, and song listening, conversation and wearing are all promoted.

In the conventional wireless stereo headset, a mode of performing master-slave switching between a master headset and a slave headset generally uses a change of state of the headset as a switching basis, for example, abnormal connection between the master headset and an electronic device, the fact that the master headset is put into a charging box, the electric quantity of the master headset is too low, and the like as the switching basis.

The inventor discovers through long-time research that in the traditional master-slave switching mode between the master earphone and the slave earphone, the change of the surrounding environment is not considered, so that in some scenes, the signal strength of the slave earphone and the host is obviously more suitable for being used as the master earphone connected with the electronic equipment to carry out data transmission with the electronic equipment.

For example, the real-time requirement of the bluetooth call scene on the transmission link is relatively high, the transmission link allows transmission for three times at most when transmitting the same packet of call audio data, if the electronic device still does not receive the corresponding audio data packet after the transmission for three times, it means that the electronic device loses the data packet, and then the voice content is lost in the call, so that bad experience is brought to the user. When the TWS earphone is used for conversation in some special situations (for example, when the TWS earphone and the host device are in an environment with stronger interference or communication between the host device and the main ear needs to penetrate through the body, the signal intensity of the slave ear and the host device is obviously better than that of the main ear and the electronic device), the main ear microphone conversation data can often generate packet loss phenomenon during transmission, and although the slave ear signal is relatively better, the slave ear microphone cannot transmit data at the moment, so that bad inspection (such as a phenomenon that a conversation partner hears a sound with a jam) can be brought to a user.

In view of the above problems, the inventors propose an earphone control method, an apparatus, a bluetooth earphone, and a storage medium provided in the embodiments of the present application, where when a first bluetooth earphone is used as a master earphone and a second bluetooth earphone is used as a slave earphone, according to signal strength between the first bluetooth earphone and an electronic device (e.g., a sound source device) and signal strength between the second bluetooth earphone and the electronic device, when the signal strength between the second bluetooth earphone and the electronic device meets a preset strength condition, the first bluetooth earphone is switched to be connected with the electronic device as the master earphone, so as to ensure data transmission quality between the second bluetooth earphone and the electronic device. When the second Bluetooth headset is a slave headset, the second signal intensity is obtained by monitoring the communication between the electronic equipment and the first Bluetooth headset based on the second Bluetooth headset; the earphone control method disclosed by the invention can be suitable for the situation that the main earphone and the auxiliary earphone acquire audio data from the sound source device, wherein the main earphone is connected with the sound source device through Bluetooth, so that the first signal intensity between the main earphone and the sound source device can be determined, the auxiliary earphone acquires the audio data through monitoring the link between the main earphone and the sound source device, so that the second signal intensity between the auxiliary earphone and the sound source device can be determined, and can be suitable for the situation that the main earphone acquires the audio data from the sound source device and then the main earphone forwards the audio data to the auxiliary earphone, but the auxiliary earphone can acquire the second signal intensity through monitoring the link between the main earphone and the sound source device, namely, in the situation, the auxiliary earphone monitors to acquire the second signal intensity, not necessarily to acquire the audio data for playing. The specific earphone control method is described in detail in the following embodiments.

Referring to fig. 1, fig. 1 is a flow chart illustrating a headset control method according to an embodiment of the present application. The earphone control method is used for realizing master-slave switching between the master earphone and the slave earphone according to the signal intensity of the master earphone and the slave earphone, and guaranteeing the data transmission quality between the master earphone and the slave earphone and the electronic equipment. In a specific embodiment, the earphone control method is applied to a first bluetooth earphone. The specific flow of this embodiment will be described below using the first bluetooth headset as an example. The following describes the flowchart shown in fig. 1 in detail, and the earphone control method specifically includes the following steps:

step S110: and acquiring the first signal intensity of the first Bluetooth headset and the second signal intensity of the second Bluetooth headset.

At present, many users are connected with a Bluetooth headset by using an electronic device, so as to realize the transmission of audio data collected by the headset and the playing of audio data to be played, and especially for users with higher demands, the users can use a TWS headset to perform data transmission with the electronic device. In actual use of the TWS headset, a master headset typically establishes a bluetooth link with the electronic device for connection, and a slave headset establishes a bluetooth link with the master headset for connection. Further, in order to obtain the signal strength between the slave earphone and the electronic device, the slave earphone needs to obtain link information between the electronic device and the master earphone, so that communication between the electronic device and the master earphone can be monitored, and further second signal strength between the slave earphone and the electronic device is obtained.

In this embodiment, referring to fig. 2, when the first bluetooth headset 702 is connected to the electronic device 701 as a master headset, the second bluetooth headset 703 may be connected to the first bluetooth headset 702 as a slave headset. The first bluetooth headset may be a headset for playing audio data of a left channel, and the second bluetooth headset may be a headset for playing audio data of a right channel, and of course, the first bluetooth headset may also be a headset for playing audio data of a right channel, and the second bluetooth headset is a headset for playing audio data of a left channel.

Because the TWS earphone is in actual use, the signal intensity between the master earphone and the electronic device and the signal intensity between the slave earphone and the electronic device are possibly changed due to the influence of the actual environment, the signal intensity between the master earphone and the electronic device and the signal intensity between the slave earphone and the electronic device can be monitored, so that when the signal intensity between the slave earphone and the electronic device is more suitable for being connected with the electronic device as the master earphone, master-slave switching between the master earphone and the slave earphone is performed. It can be understood that, since the main earphone and the electronic device are established with a bluetooth link, the bluetooth signal strength between the main earphone and the electronic device can be determined; while the slave earphone does not establish a bluetooth connection link with the electronic device, the slave earphone in the TWS earphone may establish a listening link with the electronic device, where the listening link is used to listen to the transmission condition of audio data between the master earphone and the electronic device, so that the signal strength between the slave earphone and the electronic device may also be determined.

In some embodiments, the first bluetooth headset as the master headset may begin monitoring and recording bluetooth signal strength between the first bluetooth headset and the electronic device after the bluetooth link with the electronic device is established. For example, in a call scenario, the bluetooth signal strength between the first bluetooth headset and the electronic device is monitored and recorded.

In this embodiment of the present application, the first bluetooth headset may use the bluetooth signal strength between the acquired first bluetooth headset and the electronic device as the first signal strength. The obtained first signal strength of the first bluetooth headset may be a bluetooth signal strength between the first bluetooth headset and the electronic device at a certain time, may also be a bluetooth signal strength between the first bluetooth headset and the electronic device at a plurality of times, or may also be an average bluetooth signal strength between the first bluetooth headset and the electronic device within a period of time, which is not limited herein.

In this embodiment of the present application, the first bluetooth headset as the master headset obtains the second signal intensity of the second bluetooth headset through its bluetooth link with the second bluetooth headset (slave headset), obtain the bluetooth signal intensity between second bluetooth headset and the electronic equipment promptly, further, the master headset can compare first signal intensity and the second signal intensity, judge whether satisfy the master slave switching condition according to the comparison result, if satisfy, send the switching command to the slave headset through the bluetooth link between master headset and the slave headset, so that the slave headset carries out master slave switching, and master headset itself also switches. Likewise, the second signal intensity of the second bluetooth headset may be obtained, or the bluetooth signal intensity of the second bluetooth headset between a certain time and the electronic device may be obtained, or the bluetooth signal intensity of the second bluetooth headset between a plurality of times and the electronic device may be obtained, or the average bluetooth signal intensity of the second bluetooth headset between a period of time and the electronic device may be obtained.

Step S120: and determining that the first signal intensity and the second signal intensity meet a preset intensity condition.

In this embodiment of the present application, after obtaining the first signal strength between the first bluetooth headset and the electronic device and the second signal strength between the second bluetooth headset and the electronic device, the first bluetooth headset serving as the master headset may determine whether the first signal strength and the second signal strength meet the preset strength condition according to the first signal strength and the second signal strength. If the first signal intensity and the second signal intensity meet the preset intensity condition, the main earphone is required to be switched to the second Bluetooth earphone; if the first signal intensity and the second signal intensity indicate that the main earphone is not required to be switched to the second Bluetooth earphone, at this time, the first Bluetooth earphone can be kept connected with the electronic device as the main earphone without switching the main earphone.

In some embodiments, the preset strength condition may be a condition that characterizes the signal strength of the second bluetooth headset as more suitable as the master headset. For example, the preset strength condition may be that the second signal strength of the second bluetooth headset is greater than the first signal strength of the first bluetooth headset, for example, the preset strength condition may be that the second signal strength of the second bluetooth headset is greater than the first signal strength of the first bluetooth headset by a certain value, for example, the preset strength condition may be that the first signal strength of the first bluetooth headset is less than a certain value, which is not limited herein.

It should be noted that, whether the preset intensity condition is satisfied may be determined after the signal intensities of the two headphones are acquired by the master headphone, or whether the preset intensity condition is satisfied may be determined after the signal intensities of the two headphones are acquired by the slave headphone.

Step S130: and if the signal intensity of the first Bluetooth headset and the signal intensity of the second Bluetooth headset meet the preset intensity condition, sending switching indication information to the second Bluetooth headset, wherein the switching indication information is used for indicating the second Bluetooth headset to be used as a main headset to be connected with the electronic equipment.

In this application embodiment, when determining that the first signal intensity of the first bluetooth headset and the second signal intensity of the second bluetooth headset meet the preset intensity condition, the switching between the master headset and the slave headset is performed, so that the first bluetooth headset is switched into the slave headset, and the second bluetooth headset is switched into the master headset. Specifically, the first bluetooth headset sends switching indication information to the first bluetooth headset, where the switching indication information is used to instruct the second bluetooth headset to establish bluetooth connection with the electronic device as a master headset. In some embodiments, after the first bluetooth headset sends the switch indication information to the second bluetooth headset, the first bluetooth headset may switch itself to the slave headset after receiving the indication information sent by the second bluetooth headset and used for indicating that the second bluetooth headset is ready to establish a bluetooth connection with the electronic device, disconnect the bluetooth link with the electronic device, and send the connection indication information to the second bluetooth headset while starting to switch to the slave headset, where the second bluetooth headset immediately establishes a connection with the electronic device after receiving the connection indication information. Because the first Bluetooth headset is not immediately switched to the slave headset after the switching indication information is sent, but is switched after the second Bluetooth headset is ready, the problem that the data transmission is interrupted due to the fact that the first Bluetooth headset is disconnected from the electronic device under the condition that the second Bluetooth headset does not establish a Bluetooth link between the completion and the electronic device is avoided.

It should be noted that, the first bluetooth headset may refer to a bluetooth headset currently used as a master headset in the TWS headset, and all bluetooth headsets used as the master headset may automatically implement master-slave switching between the master headset and the slave headset in the use process according to the headset control method provided in the embodiment of the present application.

According to the earphone control method, when the first Bluetooth earphone is used as the master earphone and connected with the electronic equipment, the second Bluetooth earphone is used as the slave earphone and connected with the first Bluetooth earphone, the first Bluetooth earphone obtains the first signal intensity of the first Bluetooth earphone and obtains the second signal intensity of the second Bluetooth earphone, if the first signal intensity and the second signal intensity are determined to meet the preset intensity conditions, switching indication information is sent to the second Bluetooth earphone, the switching indication information is used for indicating the second Bluetooth earphone to serve as the master earphone and be connected with the electronic equipment, so that when the signal intensity representation slave earphone of the master earphone and the slave earphone is more suitable for serving as the master earphone, the switching between the master earphone and the slave earphone is conducted, the first Bluetooth earphone is switched into the slave earphone, the second Bluetooth earphone is switched into the master earphone, the packet loss rate of data transmission between the second Bluetooth earphone and the electronic equipment is reduced, and the data transmission quality between the second Bluetooth earphone and the electronic equipment is guaranteed.

Referring to fig. 3, fig. 3 is a flow chart illustrating a headset control method according to another embodiment of the present application. The earphone control method is applied to the first bluetooth earphone, and will be described in detail with respect to the flow shown in fig. 3, where the earphone control method specifically includes the following steps:

step S210: and acquiring the first signal intensity of the first Bluetooth headset and the second signal intensity of the second Bluetooth headset.

In the embodiment of the present application, step S210 may refer to the content of the foregoing embodiment, which is not described herein.

Step S220: determining that the second signal strength is not less than a first threshold.

In this embodiment of the present application, after the first bluetooth headset serving as the master headset obtains the first signal strength between the first bluetooth headset and the electronic device, and the second signal strength between the second bluetooth headset and the electronic device, the signal strength of the second bluetooth headset may be compared with the first threshold. The first threshold may be a signal strength condition that a bluetooth headset in the TWS headset may be used as a main headset to perform data transmission with the electronic device, if the signal strength of the bluetooth headset is less than or equal to the first threshold, the bluetooth headset may not be used as the main headset to perform data transmission with the electronic device, and if the signal strength of the bluetooth headset is greater than the first threshold, the bluetooth headset may be used as the main headset to perform data transmission with the electronic device.

Step S230: and determining that the first signal intensity and the second signal intensity meet a preset intensity condition.

In this embodiment of the present application, when the signal strength of the second bluetooth headset is greater than the first threshold, it indicates that the bluetooth headset may serve as the master headset for data transmission with the electronic device. Therefore, it can be determined whether the first signal strength of the first bluetooth headset and the second signal strength of the second bluetooth headset meet the preset strength condition, and if the preset strength condition is met, the switching indication information can be sent to the second bluetooth headset so as to switch the main headset to the second bluetooth headset which is more suitable for data transmission with the electronic device.

In some embodiments, when the signal strength of the second bluetooth headset is less than or equal to the first threshold, step S230 and step S240 may not be performed, that is, when the second bluetooth headset cannot be used as the master headset, the subsequent determination of whether the first signal strength and the second signal strength meet the preset strength condition may not be performed, and the switching operation of the master headset when the preset strength condition is met. Thus, the workload of the main earphone can be effectively saved, and the power consumption of the TWS earphone is further reduced, and it can be understood that when the second signal intensity is smaller than or equal to the first threshold value, the first signal intensity is possibly larger than the first threshold value, at the moment, the first Bluetooth earphone can be used as the main earphone to carry out data transmission with the electronic equipment, and the second Bluetooth earphone can not be used as the main earphone to carry out data transmission with the electronic equipment, at the moment, the first Bluetooth earphone is more suitable for being used as the main earphone, so that the switching of the main earphone can be omitted; of course, the first signal strength and the second signal strength may be both smaller than or equal to the first threshold, and at this time, the first bluetooth headset and the second bluetooth headset do not meet the requirement of performing data transmission with the electronic device as the main headset, so that switching of the main headset may not be performed, and when the signal strength of the first bluetooth headset and the signal strength of the second bluetooth headset are both smaller than or equal to the first threshold, the signal strength of the first bluetooth headset and the signal strength of the second bluetooth headset meet the preset strength condition, and ineffective switching caused by switching operation of the main headset is performed, so that power consumption of the TWS headset is effectively reduced.

In some embodiments, when the first signal strength and the second signal strength are both less than or equal to the first threshold, since the first bluetooth headset and the second bluetooth headset cannot meet the requirement of data transmission with the electronic device, the first bluetooth headset can send out a prompt message (such as outputting a prompt voice) to prompt a user to replace the position of the bluetooth headset, so that the signal strength of the first bluetooth headset is improved, and the data transmission with the electronic device can be met.

Step S240: and sending switching indication information to the second Bluetooth headset, wherein the switching indication information is used for indicating the second Bluetooth headset to be used as a main headset to establish connection with the electronic equipment.

According to the earphone control method, when the first Bluetooth earphone is used as a master earphone and connected with the electronic equipment, the second Bluetooth earphone is used as a slave earphone and connected with the first Bluetooth earphone, the first Bluetooth earphone obtains the first signal intensity of the first Bluetooth earphone and obtains the second signal intensity of the second Bluetooth earphone, then the signal intensity of the second Bluetooth earphone is compared with the first threshold value, when the signal intensity of the second Bluetooth earphone is larger than the first threshold value, the first signal intensity and the second signal intensity are determined to meet the preset intensity condition, switching indication information is sent to the second Bluetooth earphone, and the switching indication information is used for indicating the second Bluetooth earphone to be connected with the electronic equipment as the master earphone. Therefore, when the signal intensity of the master earphone and the slave earphone is used for determining that the slave earphone is more suitable as the master earphone, the switching between the master earphone and the slave earphone is carried out, so that the first Bluetooth earphone is switched into the slave earphone, the second Bluetooth earphone is switched into the master earphone, the packet loss rate of data transmission between the slave earphone and the electronic equipment is reduced, and the data transmission quality between the slave earphone and the electronic equipment is ensured. And when the signal intensity of the second Bluetooth headset is smaller than or equal to the first threshold value, the power consumption caused by the subsequent processing steps of the first Bluetooth headset under the condition that the second Bluetooth headset does not meet the requirement of data transmission between the main headset and the electronic equipment can be avoided.

Referring to fig. 4, fig. 4 is a flow chart illustrating a headset control method according to another embodiment of the present application. The earphone control method is applied to the first bluetooth earphone, and will be described in detail with respect to the flow shown in fig. 4, where the earphone control method specifically includes the following steps:

step S310: and determining that the first Bluetooth headset is used as a main headset and is in a transmission state of audio data with the electronic equipment.

In this embodiment of the present application, when determining that the first bluetooth headset is in the transmission state of audio data between the main headset and the electronic device, for example, the TWS headset is used for a scene such as an audio call scene, a music playing scene, etc., the first signal strength of the first bluetooth headset and the signal strength of the second bluetooth headset may be obtained.

In some embodiments, the first bluetooth headset may determine whether the first bluetooth headset is in a transmission state of audio data with the electronic device according to a data type of data transmitted with the electronic device. If the data type of the data transmitted between the first Bluetooth headset and the electronic equipment is the audio data type, determining that the data between the first Bluetooth headset and the electronic equipment is in the transmission state of the audio data; if the data type of the data transmitted between the first Bluetooth headset and the electronic equipment is not the audio data type, the fact that the data between the first Bluetooth headset and the electronic equipment is not in the transmission state of the audio data can be determined.

It should be noted that, step S310 in the embodiment of the present application may be equally applicable to other embodiments.

Step S320: and periodically and respectively acquiring the average signal intensity among the first Bluetooth headset, the second Bluetooth headset and the electronic equipment as a first signal intensity and a second signal intensity.

In this embodiment of the present application, the signal intensity of the first bluetooth headset and the second bluetooth headset may be obtained by the first bluetooth headset, the second bluetooth headset, and the electronic device periodically and respectively. The specific value of the period may be, but not limited to, 1 minute, 2 minutes, or the like.

In some embodiments, the first bluetooth headset may monitor the bluetooth signal strength between itself and the electronic device, so that a time-varying relationship of the bluetooth signal strength may be obtained, or bluetooth signal strengths at multiple times may be obtained. The first bluetooth headset may periodically obtain the average signal strength according to a relationship of the obtained bluetooth signal strength varying with time or bluetooth signal strengths at a plurality of moments.

In some embodiments, the second bluetooth headset may also monitor the bluetooth signal strength between itself and the electronic device, so that a time-varying relationship of the bluetooth signal strength may be obtained, or bluetooth signal strengths at multiple times may be obtained. The second bluetooth headset may periodically obtain the average signal strength according to the relationship of the obtained bluetooth signal strength with time variation or the bluetooth signal strength at a plurality of moments. After the second Bluetooth headset obtains the average signal intensity, the counted average signal intensity can be sent to the first Bluetooth headset, so that the first Bluetooth headset can obtain the average signal intensity between the second Bluetooth headset and the electronic equipment.

Of course, the second bluetooth headset may also send the monitored signal strength between the second bluetooth headset and the electronic device to the first bluetooth headset, and then the first bluetooth headset periodically calculates the average signal strength between the second bluetooth headset and the electronic device.

In some embodiments, the first bluetooth headset periodically obtains an average signal strength between the first bluetooth headset and the electronic device, and the average signal strength between the second bluetooth headset and the electronic device may be obtained by obtaining an average signal strength in at least one period adjacent to the current time. Therefore, the obtained first signal intensity and second signal intensity can embody the signal intensity between the first Bluetooth earphone and the electronic equipment as well as the second Bluetooth earphone, and an accurate basis is provided for master-slave switching of the master earphone and the slave earphone.

Step S330: and obtaining a difference value between the second signal intensity and the first signal intensity.

In this embodiment of the present application, the first bluetooth headset may determine, according to the obtained first signal strength and the second signal strength, whether the first signal strength and the second signal strength meet a preset strength condition, and calculate a difference between the second signal strength and the first signal strength, so as to determine, according to the calculated difference, whether the preset strength condition is met.

Step S340: determining that the difference is not less than a second threshold.

In this embodiment of the present application, after the first bluetooth headset calculates the difference between the second signal strength and the first signal strength, the calculated difference may be compared with the second threshold. If the difference is smaller than the second threshold, that is, the difference between the first signal strength and the second signal strength is not large, the first signal strength and the second signal strength do not meet the preset strength condition, and switching of the main earphone is not needed. If the difference is not smaller than (i.e. smaller than or equal to) the second threshold, that is, the second signal strength is greater than the first signal strength and greater than a certain value, it may be indicated that the first signal strength and the second signal strength meet the preset strength condition, and the switching of the main earphone is required. The specific value of the second threshold may not be limited, and may be set according to actual requirements.

It should be noted that, the manner in which the first signal strength and the second signal strength determined in step S330 and step S340 satisfy the preset strength condition in the embodiment of the present application may also be applicable to the foregoing embodiment.

According to the earphone control method, when the first Bluetooth earphone serving as the master earphone is in the transmission state of audio data with the electronic equipment, the average signal intensity between the first Bluetooth earphone and the second Bluetooth earphone and the electronic equipment is obtained, then the difference between the average signal intensity of the second Bluetooth earphone and the average signal intensity of the first Bluetooth earphone is calculated, if the difference is not smaller than the second threshold, switching indication information is sent to the second Bluetooth earphone and used for indicating the second Bluetooth earphone to serve as the master earphone to be connected with the electronic equipment, so that when the signal intensity characterization slave earphone of the master earphone and the slave earphone is more suitable for serving as the master earphone, switching between the master earphone and the slave earphone is conducted, the first Bluetooth earphone is switched into the slave earphone, the second Bluetooth earphone is switched into the master earphone, the packet loss rate of data transmission between the second Bluetooth earphone and the electronic equipment is reduced, and the data transmission quality between the second Bluetooth earphone and the electronic equipment is guaranteed.

Referring to fig. 5, fig. 5 is a flowchart illustrating a headset control method according to another embodiment of the present application. The earphone control method is applied to the first bluetooth earphone, and will be described in detail with respect to the flow shown in fig. 5, where the earphone control method specifically includes the following steps:

Step S410: and acquiring the first signal intensity of the first Bluetooth headset and the second signal intensity of the second Bluetooth headset.

In this embodiment, step S410 may refer to the content of the foregoing embodiment, which is not described herein.

Step S420: and respectively acquiring a first change rate and a second change rate corresponding to the first signal intensity and the second signal intensity.

In this embodiment of the present application, when determining, according to the first signal strength and the second signal strength, whether the first signal strength and the second signal strength meet the preset strength condition, the first bluetooth headset serving as the main headset may respectively obtain, according to the obtained first signal strength and the obtained second signal strength, a first rate of change corresponding to the first signal strength, and a second rate of change corresponding to the second signal strength.

In some embodiments, the first signal strength obtained by the first bluetooth headset may be signal strengths between the first bluetooth headset and the electronic device at a plurality of times within a preset time period before the current time, and the second signal strength may be signal strengths between the second bluetooth headset and the electronic device at a plurality of times within a preset time period before the current time. The first bluetooth headset can calculate the average change rate of the signal intensity in the preset duration according to the signal intensity of the first bluetooth headset at a plurality of moments corresponding to the first bluetooth headset, and the calculated average change rate of the signal intensity corresponding to the first bluetooth headset is used as the first change rate. Similarly, the first bluetooth headset may calculate an average rate of change of the signal strength within the preset duration according to the signal strengths of the second bluetooth headset at a plurality of moments, and use the calculated average rate of change of the signal strength corresponding to the second bluetooth headset as the second rate of change.

In other embodiments, the first signal strength obtained by the first bluetooth headset may also be a first change curve of the signal strength corresponding to the first bluetooth headset, where the first change curve of the signal strength corresponding to the first bluetooth headset changes with time, and the second signal strength may also be a second change curve of the signal strength corresponding to the first bluetooth headset, where the second change curve of the signal strength corresponding to the first bluetooth headset changes with time. According to a first change curve of the signal intensity corresponding to the first Bluetooth headset, which changes along with time, the change rate of the current signal intensity (namely the slope of the first change curve at the current moment) can be obtained, and the obtained change rate is taken as the first change rate. Similarly, the change rate of the current signal strength (i.e. the slope of the second change curve at the current moment) can be obtained as the second change rate according to the second change curve of the signal strength corresponding to the second bluetooth headset, which changes with time.

Step S430: determining that the second rate of change is greater than the first rate of change.

In this embodiment, after obtaining the first rate of change of the first signal strength and the second rate of change of the second signal strength, the first bluetooth headset may compare the second rate of change with the first rate of change. If the second change rate is larger than the first change rate, it can be determined that the first signal strength and the second signal strength meet the preset strength condition, that is, the second Bluetooth headset is more suitable for data transmission between the main headset and the electronic device. If the second rate of change is not greater than the first rate of change, it may be determined that the first signal strength and the second signal strength do not meet the preset strength condition, that is, the switching of the master earphone is not required.

It can be understood that when the second rate of change is greater than the first rate of change, the first rate of change and the second rate of change may be both positive, which indicates that the rate of increase of the signal strength between the second bluetooth headset and the electronic device is greater than the rate of increase of the signal strength between the first bluetooth headset and the electronic device, that is, the signal strength of the subsequent second bluetooth headset may be greater than the signal strength of the first bluetooth headset, so that it may be determined that the first signal strength and the second signal strength meet the preset strength condition, that is, the second bluetooth headset is more suitable for data transmission with the electronic device as the main headset. If the second rate of change is greater than the first rate of change, the first rate of change and the second rate of change may be both negative, which indicates that the speed of signal strength decrease between the second bluetooth headset and the electronic device is less than the speed of signal strength decrease between the first bluetooth headset and the electronic device, that is, the signal strength of the subsequent second bluetooth headset may be greater than the signal strength of the first bluetooth headset, so that it may be determined that the first signal strength and the second signal strength meet the preset strength condition, that is, the second bluetooth headset is more suitable for data transmission between the main headset and the electronic device. If the second rate of change is greater than the first rate of change, also probably the first rate of change is negative, and the second rate of change is positive, that is to say that the signal strength of first bluetooth headset is decreasing, and the signal strength of second bluetooth headset is increasing, so, the signal strength of follow-up second bluetooth headset can be greater than the signal strength of first bluetooth headset, consequently can confirm that first signal strength and second signal strength satisfy preset intensity condition, and that is to say that second bluetooth headset is more suitable for carrying out data transmission as main earphone and electronic equipment. On the contrary, when the second change rate is greater than the first change rate, the signal intensity of the subsequent first bluetooth headset is greater than the signal intensity of the second bluetooth headset, so that the switching of the main headset is not required. It is understood that the rate of change of the signal intensity characterizes the trend of the signal intensity over a predetermined period of time, i.e. the average slope of the signal intensity curve over the predetermined period of time.

Step S440: and sending switching indication information to the second Bluetooth headset, wherein the switching indication information is used for indicating the second Bluetooth headset to be used as a main headset to establish connection with the electronic equipment.

In the embodiment of the present application, step S440 may refer to the content of the foregoing embodiment, which is not described herein.

In this embodiment of the present application, before the first bluetooth headset sends the switching indication information to the second bluetooth headset, the first bluetooth headset may further obtain a headset state of the second bluetooth headset, where the headset state includes a wearing state and a non-wearing state. The wearing state refers to a state that the Bluetooth headset is worn on the ear of the user, and the non-wearing state refers to a state that the Bluetooth headset is not worn on the ear of the user, namely, a state that the Bluetooth headset is taken out from the ear of the user.

In some embodiments, the second bluetooth headset may detect the headset state, and specifically may acquire data detected by the second bluetooth headset and used for determining the headset state, for example, the received pressure data, the detected temperature, the ambient light intensity, the capacitance measurement value, and the like, and determine that the second bluetooth headset is in the wearing state or the non-wearing state according to the data used for determining the headset state. After the second Bluetooth headset determines the headset state, the headset state can be sent to the first Bluetooth headset, and the first Bluetooth headset can obtain the headset state of the second Bluetooth headset.

Further, after acquiring the earphone state of the second bluetooth earphone, it may be determined whether the earphone state is a wearing state, and if so, it indicates that the second bluetooth earphone is being used by the user, so that the main earphone may be switched to the second bluetooth earphone. If the second Bluetooth headset is not in the wearing state, the second Bluetooth headset is not used by the user currently, and the main headset does not need to be switched to the second Bluetooth headset.

According to the earphone control method, the first Bluetooth earphone serving as the master earphone is used for acquiring the first signal intensity of the first Bluetooth earphone and the second signal intensity of the second Bluetooth earphone, then acquiring the first change rate of the first signal intensity and the second change rate of the second signal intensity, determining that the second signal intensity and the first signal intensity meet the preset intensity condition when the second change rate is larger than the first change rate, and sending switching indication information to the second Bluetooth earphone at the moment, wherein the switching indication information is used for indicating the second Bluetooth earphone to serve as the master earphone to be connected with the electronic equipment, so that when the signal intensity characterization slave earphone of the master earphone and the slave earphone is more suitable for serving as the master earphone, switching between the master earphone and the slave earphone is conducted, the first Bluetooth earphone is conveniently switched into the slave earphone, the second Bluetooth earphone is switched into the master earphone, the packet loss rate of data transmission between the second Bluetooth earphone and the electronic equipment is reduced, and the data transmission quality between the second Bluetooth earphone and the electronic equipment is guaranteed.

Referring to fig. 6, fig. 6 is a flow chart illustrating a headset control method according to still another embodiment of the present application. The earphone control method is applied to the first Bluetooth earphone, when the first Bluetooth earphone is used as a master earphone and connected with the electronic equipment, the second Bluetooth earphone is used as a slave earphone and connected with the first Bluetooth earphone, and the number of the second Bluetooth earphone is more than one.

step S510: and acquiring the first signal intensity of the first Bluetooth headset and the second signal intensity of the second Bluetooth headset.

In this embodiment of the present application, the number of second bluetooth headsets serving as slave headsets may be plural, for example, in a teleconference scenario, one master headset is connected to the electronic device, and the other slave headsets are connected to the master headset, so as to implement transmission of audio data in the teleconference. In this case, the first bluetooth headset may acquire the second signal strength of each of the second bluetooth headsets.

Step S520: and respectively acquiring the difference values of the second signal intensities corresponding to the second Bluetooth headset and the first signal intensities.

In this embodiment of the present application, the first bluetooth headset may obtain a difference between the second signal strength and the first signal strength of each second bluetooth headset, so as to obtain a plurality of differences.

Step S530: determining that a plurality of differences are not smaller than a third threshold value.

In this embodiment of the present application, after obtaining the differences between the plurality of second signal intensities and the first signal intensities, it may be determined whether a difference no smaller than a third threshold exists in the plurality of differences, and if a difference no smaller than the third threshold exists, it indicates that a second bluetooth headset corresponding to the difference no smaller than the third threshold is more suitable to be connected to the electronic device as a master headset than the first bluetooth headset, so that it may be determined that a preset intensity condition is satisfied.

Step S540: and acquiring the second Bluetooth headset corresponding to the difference value which is not smaller than the third threshold as a target Bluetooth headset.

In this embodiment of the present application, the first bluetooth headset may determine a second bluetooth headset corresponding to each difference value that is not less than the third threshold, and use the determined second bluetooth headset as the target bluetooth headset. It can be appreciated that if the above determined difference value not smaller than the third threshold value is a plurality of, a plurality of target bluetooth headsets can be determined; if the determined difference value not smaller than the third threshold value is 1, 1 target Bluetooth headset can be determined.

Step S550: and sending the switching indication information to a target Bluetooth headset with the maximum signal strength, the highest electric quantity or the maximum data quantity of the collected audio data, wherein the switching indication information is used for indicating the target Bluetooth headset to be used as a main headset to establish connection with the electronic equipment.

And if the determined number of the target Bluetooth headsets is 1, the switching indication information can be directly sent to the target Bluetooth headsets.

In some embodiments, when the number of the target bluetooth headsets is multiple, one target bluetooth headset with the maximum signal strength may be determined from the multiple target bluetooth headsets according to the signal strength between each target bluetooth headset and the electronic device, and the switching indication information may be sent to the one target bluetooth headset with the maximum signal strength, so as to switch the target bluetooth headset with the maximum signal strength into the master headset, thereby ensuring the quality of data transmission.

In other embodiments, when the number of the target bluetooth headsets is multiple, one target bluetooth headset with the maximum residual electric quantity can be determined from the multiple target bluetooth headsets according to the residual electric quantity of each target bluetooth headset, and switching indication information is sent to the one target bluetooth headset with the maximum residual electric quantity, so that the target bluetooth headset with the maximum residual electric quantity is switched to a main headset, the durability of data transmission is ensured, and the quality of data transmission is further ensured.

In still other embodiments, audio data may also be collected from the headset and transmitted to the electronic device via the master headset, e.g., in a teleconference, both the master headset and the user of the slave headset may speak and collect audio data via their headset. Under the condition, the data volume of the audio data collected by each target Bluetooth headset (for example, the data volume collected in a set time period) can be obtained respectively, then one target Bluetooth headset with the largest data volume is obtained, and switching indication information is sent to one target Bluetooth headset with the largest data volume, so that the target Bluetooth headset with the largest data volume is switched to a main headset, the audio data collected by the Bluetooth headset with the larger data volume can be reduced, the audio data can be transmitted to the electronic equipment only after being transferred by the main headset, and the data transmission volume of the Bluetooth headset is effectively saved.

According to the earphone control method, when the first Bluetooth earphone is used as the master earphone to be connected with the electronic equipment, the second Bluetooth earphone is used as the slave earphone to be connected with the first Bluetooth earphone, and the number of the second Bluetooth earphone is multiple. The first Bluetooth headset obtains the first signal intensity of the first Bluetooth headset, obtains the second signal intensity of each second Bluetooth headset, calculates the difference value between each second signal intensity and the first signal intensity to obtain a plurality of difference values, determines a target Bluetooth headset from target Bluetooth headsets corresponding to a plurality of difference values not smaller than a third threshold value when determining that the plurality of difference values are not smaller than the third threshold value, and sends switching indication information to the determined target Bluetooth headsets. Therefore, in the application scene of the plurality of slave earphones, master-slave switching of the master earphone and the slave earphone is performed according to the signal intensity of each earphone, the packet loss rate of data transmission with the electronic equipment is reduced, and the data transmission quality with the electronic equipment is ensured.

The following describes the earphone control method provided in the embodiment of the present application in a call scenario.
