step A: when Bluetooth connection is not established between the Bluetooth sound box and the sound source equipment, bluetooth positioning is carried out on a main earphone in the TWS Bluetooth earphone, and whether the main earphone is located in a first preset area around the Bluetooth sound box or not is detected;
in order to improve the positioning accuracy, the Bluetooth sound box and the TWS Bluetooth earphone can adopt a Bluetooth standard 5.1 protocol;
the Bluetooth sound box can pre-store the identity (such as Bluetooth address code) of the sound source equipment and the main earphone, when Bluetooth connection is not established between the Bluetooth sound box and the sound source equipment, the Bluetooth sound box determines the position of the main earphone by utilizing the pre-stored identity of the main earphone, and judges whether the main earphone is positioned in a pre-set first preset area or not;
for example, the first preset area around the bluetooth speaker may be an area having a distance from the bluetooth speaker smaller than a first preset value, that is, when it is determined that the distance between the main earphone and the bluetooth speaker is smaller than the first preset value (preset distance), it may be determined that the main earphone is located in the first preset area.
The sound source equipment can be a smart phone, a tablet personal computer and the like.
And (B) step (B): when the main earphone is detected to be positioned in a first preset area, a broadcast data packet is sent and a Bluetooth connection request is sent to the sound source equipment, wherein the broadcast data packet contains a first instruction, and the first instruction is an instruction for informing the main earphone to disconnect Bluetooth connection with the sound source equipment;
as shown in fig. 3, when the main earphone is not detected to be located in the first preset area, the bluetooth module of the bluetooth speaker sends out a broadcast data packet 1, where the broadcast data packet 1 may include information such as an identity identifier and a status of the bluetooth speaker, and when the main earphone is detected to be located in the first preset area, the bluetooth module of the bluetooth speaker sends out a broadcast data packet 2, that is, sends out a broadcast instruction capable of being identified by the main earphone, where the broadcast instruction is a preset instruction capable of being identified by the main earphone, so that the main earphone disconnects bluetooth connection with the audio source device;
when the main earphone is connected with the sound source equipment, if the broadcast instruction (first instruction) is received, the main earphone disconnects the Bluetooth connection with the sound source equipment, so that the sound source equipment is in a Bluetooth unconnected state, and when the sound source equipment receives a Bluetooth connection request sent by the Bluetooth sound box, bluetooth connection is established between the sound source equipment and the Bluetooth sound box, so that automatic switching of audio playing is realized;
step C: after Bluetooth connection is established between the Bluetooth sound box and the sound source equipment, bluetooth positioning is carried out on a slave earphone in the TWS Bluetooth earphone, and whether the slave earphone is located in a second preset area around the Bluetooth sound box or not is detected;
the bluetooth sound box can pre-store the identity (such as bluetooth address code) of the slave earphone, after bluetooth connection is established between the bluetooth sound box and the sound source device, the bluetooth sound box determines the position of the slave earphone by using the pre-stored identity (such as bluetooth address code) of the slave earphone, and judges whether the slave earphone is positioned in a second preset area;
wherein, the second preset area may be the same as or different from the first preset area;
for example, the second preset area may be an area having a distance from the bluetooth speaker smaller than a second preset value, where the second preset value is the same as or different from the first preset value, for example, the second preset value is the same as or smaller than the first preset value.
Step D: if the master earphone is located in the first preset area and the slave earphone is located in the second preset area, determining an included angle between the current first azimuth (azimuth of the master earphone relative to the Bluetooth module of the Bluetooth sound box, namely the azimuth of the master earphone) and the second azimuth (azimuth of the slave earphone relative to the Bluetooth module of the Bluetooth sound box, namely the azimuth of the slave earphone);
step E: and D, acquiring volume parameters corresponding to the included angles according to the prestored information, and adjusting the volume according to the corresponding volume parameters, and returning to the step D, wherein the prestored information contains the corresponding relation between different included angles and different volume parameters.
If the main earphone is detected not to be located in the first preset area or the auxiliary earphone is detected not to be located in the second preset area, the Bluetooth sound box is configured to be incapable of adjusting the volume according to the included angle between the first azimuth and the second azimuth.
For example, as shown in fig. 4, when the distances among the slave earphone 22, the master earphone 21 and the bluetooth speaker are all smaller than a preset value r, the bluetooth speaker can adjust the volume according to the current azimuth of the master earphone and the included angle formed by the azimuth of the slave earphone, wherein the included angles are different, and the volume adjusted by the bluetooth speaker is also different.
According to the audio playing control method provided by the embodiment of the invention, when the Bluetooth headset is connected with the sound source equipment, a user can realize automatic switching of audio playing by changing the position of the main headset, the audio playing is switched from the Bluetooth headset to the audio playing by the Bluetooth loudspeaker, after Bluetooth connection is established between the Bluetooth loudspeaker and the sound source equipment, the control of the volume of the Bluetooth loudspeaker can be realized through the Bluetooth headset, the control convenience of the user can be effectively improved, and the user experience is improved.
Through the audio playing control method, when the Bluetooth headset is connected with the audio device Bluetooth, when the main headset of the Bluetooth headset is taken off from a human body and gradually approaches the intelligent sound box, the main headset can be actively disconnected with the audio device when entering the preset range of the intelligent sound box (Bluetooth module), so that the intelligent sound box can be actively connected with the audio device and continue audio playing of the audio device, and the intelligent sound box can also realize the change of audio volume according to the change of the included angle formed by the position of the main headset and the position of the auxiliary headset.
In the embodiment of the invention, after the Bluetooth connection between the main earphone and the sound source equipment is disconnected, the Bluetooth module of the intelligent sound box can be connected with the sound source equipment in a back connection mode or in a corresponding broadcasting request mode;
in order to realize faster connection, any one of the intelligent sound box, the TWS Bluetooth headset and the sound source equipment comprises identification marks (such as Bluetooth addresses) of the other two parties;
in another embodiment of the present invention, the first preset area and the second preset area around the bluetooth speaker may be an area located in a certain direction of the bluetooth speaker, instead of the approximately spherical three-dimensional area as shown in fig. 4, when the master earphone and the slave earphone are positioned to detect whether they are located in the corresponding preset areas, it is necessary to determine not only the distance between the earphone and the bluetooth speaker, but also the direction in which the earphone is located, so as to determine whether they are located in the corresponding preset areas;
it may be understood that in the embodiment of the invention, the bluetooth speaker performs bluetooth positioning on the earphone by using the built-in bluetooth module, the distance between the bluetooth speaker and the earphone may be specifically the distance between the bluetooth module of the bluetooth speaker and the earphone, and the azimuth of the earphone may be specifically the azimuth of the earphone relative to the bluetooth module of the bluetooth speaker.
In addition, the Bluetooth sound box can be provided with a mark for representing the position of the Bluetooth module.
For example, in an embodiment, the larger the included angle formed by the position of the main earphone (the first position) and the position of the auxiliary earphone (the second position), the larger the sound volume adjusted by the bluetooth speaker, and the smaller the included angle formed by the direction of the main earphone and the direction of the auxiliary earphone, the smaller the sound volume adjusted by the bluetooth speaker.
Preferably, in an embodiment, the bluetooth speaker includes a housing, and a groove is disposed on a top surface of the housing, for accommodating the TWS bluetooth headset, where an included angle between a connection line between the main headset and the bluetooth module and a connection line between the main headset and the bluetooth module changes when any one of the main headset and the slave headset moves in the groove. For example, the groove is an annular groove closed in a circle, for example, the track of the annular groove is circular, elliptical, rectangular or square.
For example, referring to fig. 5, the top of the bluetooth speaker 10 (i.e. the top view of the bluetooth speaker) is provided with an annular groove 12 in which a master earphone and a slave earphone can be placed, wherein the annular groove is located in the first preset area and located in the second preset area, and the master earphone and the slave earphone can move in the annular groove, through which the earphone can be placed, and the earphone can move along the groove in the groove, so that a user can conveniently determine the position of the preset area, and the operation of the user is further facilitated;
in the embodiment of the invention, the annular groove 12 is a closed-loop groove, which can be in a circular ring shape or a square ring shape, and two earphones of the Bluetooth earphone can freely move in the annular groove.
For example, in the process that the user places the bluetooth headset in the annular groove 12, when detecting that the distance between the main headset and the bluetooth speaker in the TWS bluetooth headset is smaller than a first preset value, the bluetooth speaker disconnects the bluetooth connection between the main headset and the sound source device by sending a broadcast data packet, establishes a bluetooth connection between the bluetooth connection request and the sound source device by sending a bluetooth connection request to the sound source device, performs bluetooth positioning on the slave headset in the bluetooth headset after the bluetooth connection is established between the bluetooth speaker and the sound source device, and determines an included angle formed by the current position of the main headset and the position of the slave headset and performs volume adjustment according to the included angle if the distance between the main headset and the bluetooth speaker is smaller than the first preset value and the distance between the slave headset and the bluetooth speaker is smaller than a second preset value.
For example, referring to fig. 6-8, the volume of the bluetooth speaker may gradually decrease or increase as the included angle formed by the position of the master earphone and the slave earphone decreases.
Through the mode, the Bluetooth sound box can be automatically switched, the use of a user is convenient, the interestingness can be improved, and the user experience is improved.
For example, in an embodiment, the bluetooth speaker includes a bluetooth module, a main control unit and an audio output module, where the bluetooth module and the audio output module are connected with the main control unit, and angle information obtained by the bluetooth module is converted into a volume change instruction after being processed by the main control unit, and is transmitted to the audio output module, so as to realize volume increase and decrease.
In the embodiment of the invention, a communication mode of monitoring and forwarding can be adopted between the Bluetooth headset and the sound source equipment, namely, the master headset and the sound source equipment are connected in a Bluetooth mode, the master headset and the slave headset are also connected in a Bluetooth mode, when the sound source equipment sends information to the master headset, the slave headset acquires communication data between the sound source equipment and the master headset in a monitoring mode, and the master headset then performs verification of data correctness by forwarding the received information to the slave headset.
Preferably, in an embodiment, the step S100 may specifically include:
step S111: the Bluetooth sound box detects that the main earphone enters a first preset area around the Bluetooth sound box;
step S121: the Bluetooth sound box establishes a monitoring link with the main earphone through the Bluetooth module, monitors audio data sent to the main earphone by the sound source equipment, and receives the audio data forwarded by the main earphone through the Bluetooth module;
step S131: and the Bluetooth sound box plays, integrates and plays the audio data.
For example, referring to fig. 9, when there is a bluetooth connection between the bluetooth headset and the sound source device 30, the bluetooth speaker performs bluetooth positioning on the main headset 21 in the bluetooth headset, when the main headset 21 enters into the first preset area, the main headset 21 establishes bluetooth connection with the intelligent speaker 10, the main headset 21 receives the audio data of the sound source device 30, and at the same time, the intelligent speaker 10 listens to the communication data between the main headset 21 and the sound source device 30, and the main headset 21 forwards the acquired audio data to the intelligent speaker 10. Namely, the intelligent sound box is equivalent to a second slave earphone taking the intelligent sound box as the master earphone through a communication mode of monitoring and forwarding.
