Disclosure of Invention

The technical scheme of the application provides a wireless audio system, a wireless communication method and equipment, response time delay of the magnetic type Bluetooth headset can be effectively reduced, and the requirement that a user can use the headset by separating the headset can be met.

The method provided by the first aspect may comprise: and a Bluetooth connection is established between the audio receiving party and the audio source. The audio receiver detects whether a first audio output device of the audio receiver and a second audio output device of the audio receiver are in an engaged state or an disengaged state. When detecting that the first audio output device and the second audio output device are switched from the separated state to the pull-in state, the audio receiving party and the audio source can keep the Bluetooth connection.

Therefore, when the left ear and the right ear are switched from the attraction state to the separation state, the profile connection can be quickly established on the premise that the Bluetooth connection between the audio receiving party and the audio source is not disconnected, the Bluetooth return connection is not needed, and the response time delay of the Bluetooth headset can be effectively reduced.

The first aspect provides a method wherein if there is an existing audio connection between the audio recipient and the audio source, the existing audio connection may be disconnected; if there is no existing audio connection between the audio recipient and the audio source, the audio recipient may refuse (not accept) to establish an audio connection with the audio source. The audio recipient may accept (accept) the audio connection with the audio source when it is detected that the first audio output device and the second audio output device are in the separate state.

The method provided in the first aspect, the audio receiving party may be a bluetooth headset. The audio receiver may include a first audio output device and a second audio output device, the first audio output device and the second audio output device having magnetic components. The magnetic component can be used for attracting the first audio output device and the second audio output device. The first audio output device and the second audio output device can be a left earphone and a right earphone of the Bluetooth earphone respectively. The audio source can be an electronic device such as a mobile phone and a tablet computer.

In the following, the audio receiving side is a bluetooth headset, the first audio output device and the second audio output device are left and right bluetooth headsets, and the audio source is an electronic device such as a mobile phone.

Implementing the method provided by the first aspect, the bluetooth headset may have two states of use: in the state 1, the left earphone and the right earphone are attracted, and audio connection does not exist between the Bluetooth earphone and the electronic equipment; and 2, the left earphone and the right earphone are separated, and the Bluetooth earphone and the electronic equipment maintain audio connection or accept to establish audio connection. When the left earphone and the right earphone are switched from the attraction state to the separation state, the Bluetooth earphone and the electronic equipment can establish audio connection according to actual audio playing requirements on the premise that Bluetooth connection is not disconnected, response time delay of the Bluetooth earphone can be reduced, and the purpose that a user can use the earphones by separating the left earphone and the right earphone is met.

In combination with the first aspect, in some embodiments, the audio recipient may be a bluetooth neck headset, and the first audio output device and the second audio output device may be a left earphone and a right earphone of the bluetooth neck headset, respectively. The neck-wearing type Bluetooth headset further comprises a line control, and a processor and a Bluetooth communication processing module can be integrated in the line control. The left earphone and the right earphone can be integrated with a sensor which can be used for detecting whether the left earphone and the right earphone are in a suction state or a separation state. The Bluetooth communication processing module in the wire control can control the connection state of audio connection based on the opening and closing state between the left earphone and the right earphone on the premise of not disconnecting the Bluetooth connection between the Bluetooth earphone and the electronic equipment.

In combination with the first aspect, in some embodiments, the audio recipient may be a single earpiece of a tws (true Wireless stereo) bluetooth earpiece. The audio recipient may be a left earpiece or a right earpiece of a TWS bluetooth headset. The first audio output device and the second audio output device may be a left earphone and a right earphone of a TWS Bluetooth earphone, respectively. The left earphone and the right earphone of the TWS Bluetooth earphone can be integrated with a sensor and a Bluetooth communication processing module. The sensor can be used for detecting whether the left earphone and the right earphone are in an attraction state or a separation state. The Bluetooth communication processing module can control the connection state of audio connection based on the opening and closing state between the left earphone and the right earphone on the premise of not disconnecting the Bluetooth connection between the Bluetooth earphone and the electronic equipment.

In conjunction with the first aspect, in some embodiments, disconnecting the existing audio connection may include two implementations: mode 1. the bluetooth headset sends an audio connection disconnection request to the electronic equipment, and the electronic equipment receives the request and actively disconnects the audio connection by the bluetooth headset; mode 2. the electronic device sends an audio connection disconnection request to the bluetooth headset, and the bluetooth headset receives the request and the electronic device actively disconnects the audio connection. In the mode 2, the electronic device may send an audio disconnection request when receiving the indication information (e.g., the first indication information) of the open/close state of the left and right ears sent by the bluetooth headset.

With reference to the first aspect, in some embodiments, rejecting establishing the audio connection with the electronic device may refer to that the bluetooth headset returns a rejection response of the audio connection establishment request to the electronic device to reject the audio connection establishment request when receiving the audio connection establishment request from the electronic device. When detecting that the left earphone and the right earphone are in the suction state, no audio connection exists between the Bluetooth earphone and the electronic equipment. Therefore, when the electronic equipment has audio (call audio or media audio) to be played, the audio is not routed to the Bluetooth headset but routed to the electronic equipment (such as a mobile phone) to be played, so that the use scene of a user who does not use the headset when the left headset and the right headset are pulled in is adapted.

In conjunction with the first aspect, in some embodiments, accepting (accept) and the electronic device establishing the audio connection may include, but is not limited to, the following two ways: mode 1. the bluetooth headset actively initiates audio connection establishment and sends an audio connection establishment request to an audio source; mode 2. the bluetooth headset may return an acceptance response of the audio connection establishment request to the electronic device to accept the audio connection establishment request when receiving the audio connection establishment request from the electronic device. And when the left earphone and the right earphone are detected to be in the separated state, the Bluetooth earphone can accept the audio connection with the electronic equipment. Thus, when the electronic device has audio (call audio or media audio) to be played, the audio is routed to the bluetooth headset for playing, so as to adapt to the user usage scenario of the user using the headset when the left and right headsets are separated.

Where if the audio connection is a media audio connection (e.g., A2DP connection), then approach 1 may be employed. When the left and right earphones are in the separated state, the Bluetooth earphone can send an audio connection establishment request to the electronic equipment. If the audio connection is a conversational audio connection (e.g., an SCO connection), then approach 2 may be employed. The SCO connection needs to be established when the call traffic arrives. For example, when a user places or receives a call to trigger a call service to arrive, the electronic device may send an audio connection establishment request to the bluetooth headset. At this time, if the left and right earphones are in the separated state, the bluetooth earphone can receive the audio connection establishment request sent by the electronic device.

With reference to the first aspect, in some embodiments, the bluetooth headset may send status indication information to the electronic device to indicate the open/close status of the left headset and the right headset, so that the electronic device may display an indicator of the open/close status of the left headset and the right headset according to the status indication information. Specifically, the method comprises the following steps: when detecting that the left earphone and the right earphone are in the attraction state, the Bluetooth earphone can send first indication information to the electronic equipment, and the first indication information can be used for indicating that the left earphone and the right earphone are in the attraction state. When it is detected that the left earphone and the right earphone are in the separated state, the bluetooth earphone may send second indication information to the electronic device, where the second indication information may be used to indicate that the left earphone and the right earphone are in the separated state.

In some embodiments, in combination with the first aspect, the bluetooth headset may specifically disconnect the media audio connection (e.g., A2DP connection) between the left and right headsets and the electronic device (e.g., a mobile phone) when detecting that the left and right headsets are switched from the separated state to the closed state. In particular, the bluetooth headset may disconnect the media audio connection by sending a media audio connection (e.g., A2DP connection) disconnect request to the electronic device (e.g., a cell phone). Therefore, the left earphone and the right earphone are changed from separated to attracted, the Bluetooth earphone can be disconnected from A2DP, and the Bluetooth earphone is suitable for a scene that the left earphone and the right earphone are temporarily stopped using by a user when the user attracts.

The line control 104 may be configured with keys such as a volume up key, a volume down key, a play control key, etc. The drive-by-wire 104 may also be configured with a sound collection device such as a receiver/microphone. Magnetic components can be arranged in the left earphone 102 and the right earphone 103. The audio output device 106 may be referred to as a magnetically-attractable audio output device, such as a magnetically-attractable bluetooth headset. When the left earphone 102 and the right earphone 103 are close to each other (for example, the distance is less than 2 mm) or in contact with each other, the left earphone 102 and the right earphone 103 can be attracted together due to the respective built-in magnetic components, so that the audio output device 106 can be conveniently received by the user.

A wireless communication connection 105 may be established between the electronic device 101 and the audio output device 106.

In the transmission direction of the electronic device 101 to the audio output device 106, the electronic device 101 may transmit audio data to the audio output device 106 over the wireless communication connection 105. At this time, the role of the electronic device 101 is an audio source (audio source), and the role of the audio output device 106 is an audio sink (audio sink). In this way, the audio output device 106 may convert the received audio data into sound so that the user wearing the audio output device 106 can hear the sound.

In addition to audio data, control (e.g., previous, next, etc.) messages, call control (e.g., answer, hang up) messages, volume control messages (e.g., volume up, volume down), etc. may be played, or otherwise interacted between the electronic device 101 and the audio output device 106 based on the wireless communication connection 105. Specifically, the electronic device 101 may send a play control message and a call control message to the audio output device 106 through the wireless communication connection 105, so that play control and call control may be performed on the electronic device 101 side. For example, when a user clicks a music play key on the electronic device 101, the electronic device may send an audio play command to the audio output device 106 over the wireless communication connection 105, triggering the audio output device 106 to play music. Specifically, the audio output device 106 may send a play control message and a call control message to the electronic device 101 through the wireless communication connection 105, so that play control and call control may be performed on the audio output device 106 side. For example, when the user presses the volume up key on drive-by-wire 104, audio output device 106 may send a volume up command to electronic device 101 over wireless communication connection 105, triggering electronic device 101 to increase the volume of music playing.

The physical forms and sizes of the electronic device 101 and the audio output device 106 may also be different from those shown in fig. 1A, and the present application does not limit the physical forms and sizes.

The wireless audio system 100 shown in fig. 1A may be a wireless audio system implemented based on the bluetooth protocol. For example, the wireless communication connection 105 between the electronic device 101 and the audio output device 106 may be a bluetooth communication connection.

The structure of the audio output device 106 in fig. 1A may be as shown in fig. 1B. Wherein the content of the first and second substances,

the left earphone 102 and the right earphone 103 may each include: audio module, magnetic component and sensor. The audio module may be used to convert audio data into sound, and may be specifically an electro-acoustic transducer (electro-acoustic transducer). The magnetic component may have a magnetic material. The magnetic components in the left earphone 102 and the magnetic components in the right earphone 103 may exhibit opposite magnetic properties and thus attract each other. If the left earphone 102 and the right earphone 103 are close to each other, the magnetic components in the left earphone 102 and the right earphone 103 may attract each other to attract the left earphone 102 and the right earphone 103 together. The sensor may be used to detect whether the left earphone 102 and the right earphone 103 are drawn together. The sensor may be a hall sensor, a proximity light sensor, or the like. The sensor may be referred to as a first sensor. If the left earphone 102 and the right earphone 103 are attracted together, it can be said that the left earphone 102 and the right earphone 103 are in an attraction state; otherwise, the left earphone 102 and the right earphone 103 may be said to be in a separated state.

Drive-by-wire 104 may include: bluetooth module, treater and battery. The bluetooth module may be used to receive or transmit bluetooth signals. The audio output device 106 may establish a bluetooth communication connection with the electronic device 101 through a bluetooth module and transmit a bluetooth signal to the electronic device 101 or receive a bluetooth signal transmitted by the electronic device 101 through the bluetooth communication connection. The processor may couple the bluetooth module and the audio modules, sensors in the left and

right earphones

102, 103. The processor can be responsible for reading the instructions in the memory, decoding the instructions and executing the instructions so as to realize the wireless communication method provided by the technical scheme of the application. The battery may be used to power various components in the audio output device 106, such as a processor, audio module, sensor, bluetooth module, etc.

Without being limited to that shown in fig. 1B, the audio output device 106 may also include other components, such as a memory, a receiver, an indicator light, etc. that may be configured in the drive-by-wire 104.

Not limited to the bluetooth headset shown in fig. 1A, the left and

right headsets

102, 103 in the wireless audio system 100 may also be other types of audio output devices. For example, in a home theater scenario, the left earphone 102 and the right earphone 103 in the wireless audio system 100 may also be two speakers in the home theater scenario: left sound channel audio amplifier, right sound channel audio amplifier. A control device similar to the drive-by-wire 104 can also be connected between the two sound boxes.

Fig. 2A illustrates another wireless audio system 200 according to embodiments of the present application. As shown in fig. 2A, the wireless audio system 200 may include an electronic device 201, an audio output device 202, and an audio output device 203. The audio output device 202 and the audio output device 203 may be a left earphone and a right earphone of a set of bluetooth earphones, respectively.

Unlike the wireless audio system 100 shown in fig. 1A, there is no cable connection between the audio output device 202 and the audio output device 203. The two may communicate via a wireless communication connection 206 rather than a wired communication connection. The audio output device 202 and the audio output device 203 may be True Wireless Stereo (TWS) headphones, which may be a left headphone and a right headphone, respectively, in a set of TWS headphones.

In the wireless audio system 200, the audio output device 202 and the audio output device 203 may establish wireless communication connections with the electronic device 201, respectively. For example, the audio output device 202 may establish a wireless communication connection 204 with the electronic device 201, and may interact audio data, play control messages, talk control messages, and the like through the wireless communication connection 204. Similarly, a wireless communication connection 205 may be established between the electronic device 201 and the audio output device 203, and audio data, play control messages, talk control messages, and the like may be interacted through the wireless communication connection 205.

The physical forms and sizes of the electronic device 201, the audio output device 202, and the audio output device 203 may also be different from those shown in fig. 2A, and this is not limited in this embodiment of the application.

The wireless audio system 200 shown in fig. 2A may be a wireless audio system implemented based on the bluetooth protocol. For example, the wireless communication connections (e.g., wireless communication connection 204, wireless communication connection 205, wireless communication connection 206) between the electronic device 201, the audio output device 202, and the audio output device 203 may employ bluetooth communication connections.

The audio output device 202 and the audio output device 203 in fig. 2A may have a structure as shown in fig. 2B. The audio output device 202, the audio output device 203 may each include: bluetooth module, magnetic part, audio module, sensor and processor. It can be seen that, unlike the audio output device 106 in the wireless audio system 100 shown in fig. 1A, the audio output device 202 and the audio output device 203 respectively integrate the functions of the drive-by-wire 104 of the audio output device 106.

Not limited to that shown in fig. 2B, the

audio output devices

202 and 203 may also include other components, such as configurable memory, headphones, indicator lights, and the like.

Not limited to the bluetooth headset shown in fig. 2A, the

audio output devices

202 and 203 in the wireless audio system 200 may be other types of audio output devices. For example, in a home theater scenario, the

audio output devices

202 and 203 in the wireless audio system 200 may also be two speakers in the home theater scenario: left sound channel audio amplifier, right sound channel audio amplifier.

Based on the foregoing wireless audio system, an embodiment of the present application provides a wireless communication method, which is applicable to a pair of magnetic bluetooth headsets, where the pair of magnetic bluetooth headsets includes a left headset (left bud) and a right headset (right bud).

In the wireless communication method provided by the embodiment of the application, after the magnetic type Bluetooth headset is successfully matched with the electronic equipment, the electronic equipment is controlled to be connected with the audio frequency between the magnetic type Bluetooth headset based on the attraction/separation state of the left headset and the right headset under the condition that the Bluetooth connection is not disconnected. Specifically, when the left earphone and the right earphone are in an attraction state, the existing audio connection between the magnetic type Bluetooth earphone and the electronic equipment is disconnected; when the left earphone and the right earphone are in a separated state, audio connection can be established between the magnetic type Bluetooth earphone and the electronic equipment. Like this, when the user is with the left and right sides earphone of actuation separately, magnetism is inhaled formula earphone and electronic equipment and only need be rebuild the audio frequency and be connected, and need not to carry out the bluetooth and return to the company, can effectively reduce magnetism and inhale the response time delay of formula bluetooth earphone when controlling the earphone and switching from the actuation state to the separation state, can satisfy the user and separately control the demand that the earphone just can use the earphone.

The attracting/separating states of the left earphone and the right earphone of the magnetic type Bluetooth earphone correspond to different user use scenes. Specifically, when the left and right earphones are closed, it means that the user does not use the bluetooth earphone for the moment. At this time, if the electronic device has audio to be played, the audio can be routed to an audio output device (such as a speaker, a receiver, etc.) of the electronic device for playing. When the left and right headsets are separated, this means that the user is using a bluetooth headset. At this time, if the electronic device has audio to play, the audio can be routed to the bluetooth headset for playing.

The bluetooth connection and audio connection according to the embodiment of the present application will be described below.

(1) Bluetooth connection

Bluetooth connections are bluetooth physical connections, such as connectionless Asynchronous Connections (ACL). A bluetooth connection may be established by a master device (e.g., the device that initiated the connection request) and a slave device (e.g., the device that received the connection request) via an inquiry (inquiry), paging (paging) process. In one case, the master device is an electronic device (e.g., a cell phone) and the slave device is a bluetooth headset. In another case, the master device is a bluetooth headset and the slave device is an electronic device (e.g., a cell phone).

(2) Audio connection

The audio connection (audio connection) may include: call audio connection (call audio connection), media audio connection (media audio connection). Wherein the call audio connection may be used to transmit voice data and the media audio connection may be used to transmit media audio data. The call audio connection may be a connection oriented Synchronous Connection (SCO) for call scenarios. The media audio connection may be an advanced audio distribution profile (A2 DP) connection.

Different audio connections are also correspondingly configured with different application profile connections for audio control. Specifically, the call audio connection may be configured with a call audio control connection, and may be used to transmit call control (e.g., answer, hang-up, etc.) signaling. The call audio control connection may be a hands-free profile (HFP) connection. The media audio connection may be configured with a media audio control connection and may be used to transmit media audio playback control (e.g., previous, next, pause, play, volume control, etc.) signaling. The media audio control connection may be an audio/video remote control profile (AVRCP) connection.

The application profile connection is established based on a logical link control and adaptation protocol (L2 CAP) channel. The L2CAP is located above a baseband (baseband), and is responsible for converting baseband data into a data packet format that is easy for application decoding, and provides functions such as protocol multiplexing and quality of service switching. The establishment of bluetooth physical connection is described in (1) above, but if an upper layer application (e.g. A2DP) needs to communicate between the master device and the slave device, it also needs to establish corresponding L2CAP channels on the L2CAP layer, and these channels are used for various application profiles to communicate. At the L2CAP layer, an L2CAP channel corresponding to an application profile may be represented by a Channel Identity (CID). When a profile is no longer used, the L2CAP channel corresponding to the profile is to be cleared.

However, L2CAP supports only ACL data transfer and does not support SCO data transfer.

(3) Media audio connection establishment procedure

Taking the A2DP connection as an example, as shown in fig. 3, the establishment process of the media audio connection may include the following steps:

step 1, the master device and the slave device establish an L2CAP channel based on ACL connection. Among them, the L2CAP channel for A2DP may include: l2CAP channel for transmitting signaling (signaling), L2CAP channel for transmitting stream (stream). Wherein, the L2CAP channel for signaling may be referred to as AVDTP signaling L2CAP channel, and the L2CAP channel for stream may be referred to as AVDTP stream L2CAP channel.

And 2, the master device and the slave device establish the A2DP connection based on the L2CAP channel used for the A2DP, and specifically, the method can comprise the steps 2-1 to 2-5.

Step 2-1. stream endpoints (stream endpoints) discovery process.

For example, through the AVDTP signaling L2CAP channel, the master device may send an AVDPT _ DISCOVER command to the slave device for discovering Stream Endpoints (SEPs) in the device. Accordingly, the slave device returns a response that carries an identification of the SEP (SEID) that the slave device can provide.

Step 2-2. capability (capabilities) query process.

For example, after discovering the SEP, the master device may send an AVDPT _ GET _ CAPABILITIES command to the slave device over the AVDTP signaling L2CAP channel for obtaining services that the SEP of the slave device is capable of providing. Accordingly, the slave device feeds back the services that the SEP can provide to the master device.

Step 2-3. stream configuration (stream configuration) process.

For example, after querying the services that can be provided by the SEP of the slave device, through the AVDTP signaling L2CAP channel, the master device may send an AVDPT _ SET _ CONFIGURATION command to the slave device for configuring the services provided by the SEP of the slave device, such as configuring channels of audio, sampling rate, and so on.

And 2-4, establishing a stream (stream) process.

For example, after the stream configuration is completed, the master device may send an AVDPT OPEN command to the slave device for creating a stream through an AVDTP signaling L2CAP channel. The created stream may also be referred to as a stream connection (streaming connection), e.g., an A2DP connection. To this end, the A2DP connection establishment is complete.

Step 2-5. stream start (stream start) process.

For example, over the AVDTP signaling L2CAP channel, the master device may send an AVDPT _ START command to the slave device for starting the stream. After streaming is initiated, the streaming media audio data is available. Here, media audio refers to mono (mono) and stereo (stereo) audio, as distinguished from speech audio transmitted over SCO connections. Subsequently, the master and slave devices may CLOSE the stream, e.g., disconnect the A2DP connection, via an AVDPT _ CLOSE command.

Similar to the establishment of the A2DP connection, the AVRCP connection is also established based on bluetooth connection (ACL) and L2CAP channels, and details are not repeated here. The AVRCP specification may be referred to for the AVRCP connection establishment procedure.

(4) Call audio connection establishment procedure

Taking the SCO connection as an example, as shown in fig. 4, the establishment process of the call audio connection may include the following steps:

step 1, the master device sends an SCO connection establishment request to the slave device, and the establishment of the SCO connection is initiated.

And 2, the slave equipment returns an acceptance response of the SCO connection establishment request to the master equipment.

The SCO connection establishment request may be LMP _ SCO _ link _ req signaling, and the SCO connection establishment request acceptance response may be LMP _ accepted signaling. If the slave device is not able to establish the SCO connection, LMP _ not _ accepted (reject answer to SCO connection establishment request) may be returned indicating that the SCO connection cannot be established.

Not limited to that shown in fig. 4, the establishment of the SCO connection may also be initiated by the slave device. Subsequently, the master and slave devices may disconnect (or remove) the SCO connection by removing the SCO connection establishment request (e.g., LMP _ remove _ SCO _ link _ req signaling).

In particular, an SCO connection may be established by the master and slave devices in response to an internal event or user action (making or receiving a call). When the call is switched from the answering state of the Bluetooth earphone to the answering of the earphone and the loudspeaker of the electronic equipment, the SCO connection is disconnected. The SCO connection may be used to transfer voice data as an adjunct to the HFP connection. How to establish HFP connection will be mentioned later, and will not be described in detail here. The SCO connection can be established only after the ACL connection has been established. Because, the HFP connection establishment needs ACL-based connection.

(5) Call audio control connection establishment

Taking HFP connection as an example, as shown in fig. 5, the establishment process of the call audio control connection may include the following steps:

step 1, the master device and the slave device establish an L2CAP channel for Radio Frequency Communication (RFCOMM) based on ACL connection.

And 2, the master device and the slave device establish RFCOMM connection based on the L2CAP channel. For the establishment process of the RFCOMM connection, General Access Profile (GAP) and Serial Port Profile (SPP) may be referred to.

And 3, responding to user operation (making a call or receiving a call) or an internal event, and establishing a service level connection (establish service level connection) between the master device and the slave device based on the existing RFCOMM connection. By this point, HFP connection establishment is completed.

Subsequently, the master device and the slave device may release the service level connection (e.g., disconnect HFP connection) through a service level connection removal procedure (service level connection removal procedure). The established service level connection is released and its corresponding RFCOMM connection is removed. Likewise, the audio connection (SCO connection) corresponding to the service level connection is also removed.

With regard to the service level connection establishment process and the service level connection removal process, HFP specification may be referred to.

Fig. 6 shows an overall flow of a wireless communication method provided in an embodiment of the present application. The following is developed.

S101, the Bluetooth headset and the electronic equipment are successfully paired and Bluetooth connection is established.

Wherein the pairing may create a shared key between the bluetooth headset and the electronic device: link Key (Link Key). The Link Key (Link Key) is used for the bluetooth headset and the electronic device to authenticate each other and encrypt exchanged data.

The bluetooth connection may refer to a bluetooth physical connection, such as an ACL connection. The Bluetooth headset and the electronic equipment can establish ACL connection through inquiry (inquiry) and paging (paging) processes.

When the bluetooth of the bluetooth headset and the electronic device is turned on, the bluetooth headset and the electronic device start to execute S101.

In one approach, as shown in FIG. 7A, a user may click on the Bluetooth option 401 in a drop-down status bar 400 displayed by the electronic device to turn on Bluetooth of the electronic device. Alternatively, as shown in fig. 7B, the user may also turn on bluetooth of the electronic device through the bluetooth switch 405 in the "setup" interface 403 of the electronic device. The "setting" is an application or service on the electronic device, and may be responsible for configuring various functions of the electronic device, such as an airplane mode, wireless fidelity (Wi-Fi), bluetooth, a mobile network, and the like. Not limited to the two ways shown in fig. 7A and 7B, the bluetooth of the electronic device may be triggered to be turned on by an internal event. The internal event may be, for example, an open event of a sharing service such as "Huawei". The opening of sharing service of 'Huawei' triggers the opening of Bluetooth and Wi-Fi.

The Bluetooth headset can generally start Bluetooth after being started, and a user does not need to manually start the Bluetooth additionally.

And S102, the Bluetooth headset (through a proximity optical sensor, a Hall sensor and the like) can detect the opening and closing state between the left headset and the right headset. The open-close state can comprise the following two states: a pull-in state and a separate state. If the left earphone and the right earphone are attracted together, the left earphone and the right earphone can be called to be in an attraction state; otherwise, the left earphone and the right earphone can be said to be in a separated state.

S103, when the left earphone and the right earphone are detected to be in the suction state, the Bluetooth earphone judges whether audio connection exists between the Bluetooth earphone and the electronic equipment or not under the condition that Bluetooth connection (ACL connection) between the Bluetooth earphone and the electronic equipment is not disconnected. Disconnecting the existing audio connection if the existing audio connection exists; otherwise, the audio connection with the electronic equipment is refused to be established.

Here, the rejecting of the audio connection with the electronic device may mean that the bluetooth headset returns a rejection response of the audio connection establishment request to the electronic device to reject the audio connection establishment request when receiving the audio connection establishment request from the electronic device.

For example, when the left earphone and the right earphone are detected to be in the attraction state, no audio connection exists between the Bluetooth earphone and the electronic device. Therefore, when the electronic equipment has audio (call audio or media audio) to be played, the audio is not routed to the Bluetooth headset but is played by the electronic equipment (such as a mobile phone) so as to adapt to the use scene of a user who does not use the headset when the left headset and the right headset are pulled in.

And S104, when the left earphone and the right earphone are detected to be in the separated state, the Bluetooth earphone judges whether audio connection exists between the Bluetooth earphone and the electronic equipment under the condition that Bluetooth connection (ACL connection) between the Bluetooth earphone and the electronic equipment is not disconnected, and if the audio connection does not exist, the Bluetooth earphone accepts (accept) to establish audio connection with the electronic equipment.

Here, accepting (accept) and the electronic device to establish the audio connection may include, but is not limited to, the following two ways:

mode 1. the bluetooth headset actively initiates audio connection establishment, for example, sends an audio connection establishment request to the electronic device;

mode 2. the bluetooth headset may return an acceptance response of the audio connection establishment request to the electronic device to accept the audio connection establishment request when receiving the audio connection establishment request from the electronic device.

For example, when the left earphone and the right earphone are detected to be in the separated state, the Bluetooth earphone accepts to establish audio connection with the electronic device. Thus, when the electronic device has audio (call audio or media audio) to be played, the audio is routed to the bluetooth headset for playing, so as to adapt to the user usage scenario of the user using the headset when the left and right headsets are separated.

The audio connection in the overall flow shown in fig. 6 may be a call audio connection (e.g., SCO connection), a media audio connection (e.g., A2DP connection). The following embodiments will explain in detail how to control the connection status (disconnection or not) of the media audio connection (such as A2DP connection) and the call audio connection (such as SCO connection) between the electronic device and the magnetic-type bluetooth headset based on the engaging/disengaging status of the left headset and the right headset.

It can be seen that, in the wireless communication method provided in the embodiment of the present application, the bluetooth headset may have two usage states as shown in fig. 8: in the state 1, the left earphone and the right earphone are attracted, and audio connection does not exist between the Bluetooth earphone and the electronic equipment; and 2, the left earphone and the right earphone are separated, and the Bluetooth earphone and the electronic equipment are in audio connection or accept to establish audio connection. When the left earphone and the right earphone are switched from the attraction state to the separation state, the Bluetooth earphone and the electronic equipment can quickly establish audio connection according to actual audio playing requirements (if media audio needs to be played) on the premise that the Bluetooth connection is not disconnected, the response time delay of the Bluetooth earphone can be effectively reduced, and the purpose that the user uses the earphones by separating the left earphone and the right earphone is met.

In addition, the electronic device can also present the opening and closing state of the ear and the right earphone through a User Interface (UI) so as to realize the visualization of the opening and closing state on the electronic device side. Specifically, the bluetooth headset may send status indication information to the electronic device to indicate the open/close status of the left headset and the right headset. The electronic device may then display an indicator of the open and closed state of the left and right earphones. As shown in fig. 9A-9B, the electronic device may specifically display the indicator in a status bar. Wherein:

as exemplarily shown in fig. 9B, when the left earphone and the right earphone are in the attraction state, the electronic device may display an indicator 503 on the status bar, and the indicator 503 may be used to indicate that the left earphone and the right earphone of the bluetooth earphone are in the attraction state. The indicator 503 may be referred to as a first indicator.

As exemplarily shown in fig. 9A, when the left earphone and the right earphone are in the separated state, the electronic device may display an indicator 501A on the status bar, where the indicator 501A may be used to indicate that the left earphone and the right earphone of the bluetooth earphone are in the separated state. The indicator 501A may be referred to as a second indicator. Additionally, while displaying the indicator 501A, the electronic device can also display the indicator 501B. Indicator 501B may be used to indicate the remaining power of the bluetooth headset.

In addition, as exemplarily shown in fig. 9C, when the bluetooth of the electronic device is turned on but the bluetooth headset is not connected, the electronic device may display an indicator 505 in the status bar, and the indicator 505 may be used to indicate that the bluetooth of the electronic device is turned on but the bluetooth headset is not connected. The indicator 505 may be referred to as a third indicator.

The first indicator, the second indicator, and the third indicator are different to distinctively indicate different states of the bluetooth headset. The first indicator, the second indicator and the third indicator may also present other appearances, which are not limited to the appearances shown in fig. 9A to 9C, and the embodiment of the present application does not limit this.

In this embodiment, when the bluetooth headset is a TWS headset, the implementation of the wireless communication method provided in this embodiment of the present application on the bluetooth headset side may be performed by a left headset or a right headset in the TWS headset, or may be performed independently by the left headset and the right headset at the same time.

The wireless communication method provided by various embodiments of the present application will be described in detail below.

Example one

This embodiment will discuss how to control the media audio connection between the bluetooth headset and the electronic device (e.g., a mobile phone) based on the open/close states of the left and right magnetic attraction type bluetooth headsets. Here, the media audio connection may be, for example, an A2DP connection.

In this embodiment, for media audio connection (e.g., A2DP connection), when the left earphone and the right earphone are in the pull-in state, the bluetooth earphone may determine whether a media audio connection exists between the bluetooth earphone and the electronic device, and if the media audio connection exists, the media audio connection may be disconnected; otherwise, the media audio connection establishment request may be denied upon receipt of the media audio connection establishment request from the electronic device.

Fig. 10 illustrates a wireless communication method according to a first embodiment. In the method shown in fig. 10, a bluetooth connection (ACL connection) is established and maintained between the bluetooth headset and the electronic device. As shown in fig. 10, taking the example that the media audio connection is an A2DP connection, the method may include:

stage 1 (stage 1A to stage 1C): the left and the right earphones are in a suction state

Stage 1A (S201-S202): the electronic equipment displays an indicator that the left earphone and the right earphone of the Bluetooth earphone are in the suction state.

S201, when the left earphone and the right earphone are detected to be attracted, the Bluetooth earphone can also send state indicating information to the electronic equipment (such as a mobile phone), and the state indicating information can be used for indicating that the left earphone and the right earphone are in the attraction state. The status indication information may be referred to as first indication information.

Specifically, when the left earphone and the right earphone are detected to be sucked, the bluetooth earphone can firstly send the first indication information to the electronic device through the connection of A2DP, and then disconnect the connection of A2DP between the bluetooth earphone and the electronic device. Not limited to this, if there is another application level (profile) connection, for example, HFP connection, between the bluetooth headset and the electronic device, the bluetooth headset may also send the first indication information to the electronic device through the other application level connection, and at this time, the bluetooth headset may also disconnect the A2DP connection with the electronic device first and then send the first indication information through the other application level connection.

S202, after the first indication information sent by the Bluetooth headset is received in S201, the electronic equipment can display an indicator for attracting the left headset and the right headset. The indicator is the first indicator. As shown in fig. 9B, the electronic device may specifically display a first indicator in the status bar.

The bluetooth headset may specifically send the first indication information to the electronic device (e.g., a mobile phone) when detecting that the left and right headsets are switched from the detached state to the attached state. Therefore, the left earphone and the right earphone are switched from separation to suction, the electronic equipment can receive the state indication information and display the first indicator, and a user can immediately sense the state switching of the left earphone and the right earphone through the electronic equipment. The bluetooth headset may periodically transmit the indication information of the open/close states of the left and right headsets to the electronic device at a short period (for example, 5 milliseconds), not only when the open/close states of the left and right headsets are switched.

Stage 1B (S203-S204): the bluetooth headset disconnects A2DP between it and the electronic device.

S203, when the left earphone and the right earphone are detected to be sucked, if there is an A2DP connection between the bluetooth earphone and the electronic device, the bluetooth earphone may disconnect an A2DP connection between the bluetooth earphone and the electronic device. Specifically, the bluetooth headset may send an A2DP disconnect request to an electronic device (e.g., a cell phone). The A2DP disconnect request may be the AVDPT _ CLOSE command mentioned in the foregoing description of fig. 3. Not shown, the electronic device may accept the disconnection request after receiving the A2DP disconnection request from the bluetooth headset. To this end, the A2DP connection is broken. However, the bluetooth connection between the bluetooth headset and the electronic device is not disconnected, and remains connected when the left and right headsets are attached.

The bluetooth headset may specifically send an A2DP disconnection request to an electronic device (e.g., a mobile phone) when detecting that the left and right headsets are switched from the detached state to the attached state. Therefore, the left earphone and the right earphone are changed from separated to attracted, the Bluetooth earphone is disconnected from A2DP, and the Bluetooth headset is suitable for a scene that the user attracts the left earphone and the right earphone to suspend using the Bluetooth earphone.

S204, after the connection of A2DP is disconnected, if the media audio is not played completely, the electronic device may play the remaining media audio.

That is to say, the left earphone and the right earphone of the bluetooth earphone are attracted, the A2DP connection between the bluetooth earphone and the electronic device is disconnected, and the media audio which is not played can be played by the electronic device.

Stage 1C (S205-S208): media audio is played.

S205, the electronic device can determine that media audio is to be played.

Specifically, a media audio application (e.g., a media player, a voice assistant, etc.) on the electronic device may generate a media audio play event in response to a user operation (e.g., a media audio play operation) or an internal event, at which point the electronic device may determine that there is media audio to play.

S206, after determining that there is media audio to play, the electronic device may send an A2DP connection establishment request to the bluetooth headset.

S207, upon detecting the left and right headset puffs, the bluetooth headset may reject the A2DP connection establishment request.

S208, after the bluetooth headset refuses to establish the A2DP connection, the electronic device may play the media audio.

For example, when the left and right earphones of the bluetooth earphone are attracted, the A2DP connection between the bluetooth earphone and the electronic device is disconnected, and a media audio service comes, so that the media audio can be played by the electronic device.

Stage 2 (stage 2A to stage 2C): the left and right earphones are in a separated state

Stage 2A (S209-S211): the bluetooth headset accepts an A2DP connection to be established with the electronic device.

S209, upon detecting that the left earphone and the right earphone are separated, if there is no existing A2DP connection between the bluetooth earphone and the electronic device, the bluetooth earphone may transmit an A2DP connection request to the electronic device (e.g., a cell phone). The A2DP connection request may be an AVDPT _ OPEN command sent by the bluetooth headset to the electronic device during stream setup (stream setup) described in step 2-4 of fig. 3.

The bluetooth headset may specifically send an A2DP connection request to an electronic device (e.g., a mobile phone) when detecting that the left and right headsets are switched from the closed state to the open state. Therefore, the left earphone and the right earphone are separated from the attraction, the Bluetooth earphone initiates the connection establishment of A2DP, and the requirement that the user needs to use the earphones when separating the left earphone and the right earphone is met more quickly.

The connection establishment of the A2DP is not actively initiated when the opening and closing states of the left earphone and the right earphone of the Bluetooth earphone are switched, and the electronic equipment can periodically send connection establishment requests of the A2DP to the electronic equipment. For example, the electronic device sends an A2DP connection establishment request to the bluetooth headset once every 0.1 second. Accordingly, after receiving an A2DP connection establishment request from the electronic device, the bluetooth headset may accept or refuse to establish an A2DP connection depending on left and right headset states. When the left earphone and the right earphone are separated, the Bluetooth earphone can accept to establish A2DP connection; when the left and right earpieces are engaged, the bluetooth earpiece may refuse to establish an A2DP connection.

Upon detecting that the left and right earpieces are separated, the bluetooth headset may maintain an A2DP connection with the electronic device if there is an existing A2DP connection between the bluetooth headset and the electronic device.

S210, accordingly, after receiving the A2DP connection establishment request from the bluetooth headset, the electronic device may accept the A2DP connection establishment request. Specifically, the electronic device may return a response to the bluetooth device, which may indicate that the electronic device accepts to establish the A2DP connection.

S211, the connection establishment of A2DP is completed. Referring to the foregoing description of fig. 3, the A2DP connection may be a streaming connection established based on a bluetooth connection for the L2CAP channel of A2 DP. Because the bluetooth connection is kept between bluetooth headset and the electronic equipment, consequently, when left and right earphone parts, can establish A2DP based on existing bluetooth connection between bluetooth headset and the electronic equipment and connect, need not to carry out the bluetooth and return to the company, reduced bluetooth headset's response delay.

For the connection establishment procedure of A2DP, reference may be made to the related content of fig. 3, which is not described herein again.

Stage 2B (S212-S213): the electronic device displays an indicator that the left and right earpieces of the bluetooth earpiece are in a separated state.

S212, when the left earphone and the right earphone are detected to be separated, the bluetooth earphone may further send status indication information to the electronic device (e.g., a mobile phone), where the status indication information may be used to indicate that the left earphone and the right earphone are in the separated state. The status indication information may be referred to as second indication information.

Specifically, upon detecting that the left and right earphones are separated, the bluetooth headset may send the second indication information to the electronic device through the A2DP connection. Without being limited thereto, if there is another application level (profile) connection, for example, HFP connection, between the bluetooth headset and the electronic device, the bluetooth headset may also send the second indication information to the electronic device through the other application level connection.

S213, after receiving the second indication information transmitted by the bluetooth headset in S212, the electronic device may display an indicator that the left and right headsets are separated. The indicator is the aforementioned second indicator. As shown in fig. 9A, the electronic device may specifically display a second indicator in the status bar.

The bluetooth headset may specifically send the second indication information to the electronic device (e.g., a mobile phone) when detecting that the left and right headsets are switched from the closed state to the open state. Therefore, the left earphone and the right earphone are separated from the attraction state, the electronic equipment can receive the state indication information and display the second indicator, and a user can immediately sense the state switching of the left earphone and the right earphone through the electronic equipment. The bluetooth headset may periodically transmit the indication information of the open/close states of the left and right headsets to the electronic device at a short period (e.g., 5 milliseconds), not only when the open/close states of the left and right headsets are switched.

Stage 2C (S214-S216): media audio is played.

S214, the electronic device can determine that media audio is available to be played.

After determining that there is media audio to play, the electronic device may send the media audio data to the bluetooth headset over the A2DP connection S215.

S216, after the media audio data from the electronic equipment is received, the Bluetooth headset can play the media audio.

It can be seen that, the method provided in the first embodiment can realize that the usage scene of the bluetooth headset switches along with the switching of the open/close states of the left and right headsets: when the left earphone and the right earphone are attracted, the A2DP connection is disconnected, and the Bluetooth earphone is suspended from playing the media audio; when the left and right earpieces are separated, the A2DP connection is established and the media audio is played using the bluetooth earpiece.

Similarly, the bluetooth headset may also control the connection state (disconnection or not) of the media audio control connection (such as AVRCP connection) between the electronic device and the magnetic bluetooth headset without disconnecting the bluetooth connection based on the pull-in/pull-out states of the left and right headsets. Specifically, when the left earphone and the right earphone are attracted, if AVRCP connection exists between the Bluetooth earphone and the electronic equipment, the AVRCP connection can be disconnected; when the left and right headsets are separated, the bluetooth headset may create an AVRCP connection with the electronic device or may maintain an existing AVRCP connection. Therefore, when the left earphone and the right earphone are switched from the attraction state to the separation state, the AVRCP connection is established, and the requirements of a user for controlling media audio playing by using the Bluetooth earphone, such as volume increase/decrease, playing/pause and the like, can be met.

In a particular case, during a period of time (e.g., 1 minute) after the bluetooth headset is paired with the electronic device and the bluetooth connection is established, whether the left and right headsets of the bluetooth headset are in the detached state or the attached state, the bluetooth headset maintains the initially established A2DP connection with the electronic device without disconnecting the A2DP connection. After this time, if the left and right earphones are in the pull-in state, the bluetooth earphone may disconnect the A2DP connection; if the left and right earpieces are in the separated state, the bluetooth earpiece may continue to maintain the A2DP connection.

Example two

The present embodiment will discuss how to control a call audio connection (call audio connection) between a bluetooth headset and an electronic device (e.g., a mobile phone) based on the open/close states of left and right magnetic earphones of the bluetooth headset. Here, the call audio connection may be, for example, an SCO connection. Unlike media audio connections, the establishment of an SCO connection requires user action (answering a call) or internal event triggering. For example, a call audio connection needs to be established when there is call audio service.

In this embodiment, for a call audio connection (e.g., SCO connection), when the left earphone and the right earphone are in the attraction state, the bluetooth earphone determines whether a call audio connection exists between the bluetooth earphone and the electronic device, and if the call audio connection exists, the call audio connection may be disconnected; otherwise, the call audio connection establishment request may be rejected upon receiving the call audio connection establishment request from the electronic device.

Fig. 11 illustrates a wireless communication method according to a first embodiment. In the method shown in fig. 11, a bluetooth connection (ACL connection) is established and maintained between the bluetooth headset and the electronic device. As shown in fig. 11, taking the call audio connection as an example of an SCO connection, the method may include:

Stage 1A (S301-S302): the electronic equipment displays an indicator that the left earphone and the right earphone of the Bluetooth earphone are in the suction state.

S301, when the left earphone and the right earphone are detected to be attracted, the Bluetooth earphone can also send state indicating information to the electronic equipment (such as a mobile phone), and the state indicating information can be used for indicating that the left earphone and the right earphone are in the attraction state. The status indication information may be referred to as first indication information.

Specifically, when the left earphone and the right earphone are detected to be engaged, the bluetooth earphone may first transmit the first indication information to the electronic device through an application level (profile) connection, such as HFP connection or A2DP connection.

S302, after the first indication information sent by the Bluetooth headset is received in S301, the electronic device can display an indicator for attracting the left headset and the right headset. The indicator is the first indicator. As shown in fig. 9B, the electronic device may specifically display a first indicator in the status bar. For a specific description of S301, refer to S202 in the first embodiment, which is not described herein again.

Stage 1B (S303-S304): the bluetooth headset disconnects the SCO connection between the bluetooth headset and the electronic device.

And S303, when the suction of the left earphone and the right earphone is detected, if the existing SCO connection exists between the Bluetooth earphone and the electronic equipment, the Bluetooth earphone can disconnect the existing SCO connection. Specifically, the bluetooth headset may send an SCO disconnection request to an electronic device (e.g., a mobile phone). Not shown, the electronic device may accept the disconnection request upon receiving the SCO disconnection request from the bluetooth headset. To this end, the SCO connection is broken. However, the bluetooth connection between the bluetooth headset and the electronic device is not disconnected, and the connection is still maintained when the left and right headsets are attracted.

The bluetooth headset may specifically send an SCO disconnection request to the electronic device (e.g., a mobile phone) when detecting that the left and right headsets are switched from the detached state to the attached state. Therefore, the left earphone and the right earphone are changed from separated to attracted, the Bluetooth earphone is disconnected with the SCO, and the Bluetooth earphone is suitable for a scene that the left earphone and the right earphone are suspended to use the Bluetooth earphone when the user attracts.

S304, after the SCO connection is disconnected, if the call is not ended, the electronic equipment can play the call audio.

For example, the left earphone and the right earphone of the bluetooth earphone are attracted, the SCO connection between the bluetooth earphone and the electronic device is disconnected, and the call audio of the call which is not ended can be routed to the electronic device side for playing.

Stage 1C (S305-S308): and playing the call audio.

S305, the electronic equipment detects user operations such as answering or making a call.

Specifically, a Phone application (Phone) on the electronic device may receive such user operations.

After detecting the user operation, the electronic device may send an SCO connection establishment request to the bluetooth headset S306. Specifically, the SCO connection establishment request may be the LMP _ SCO _ link _ req signaling mentioned in fig. 4.

S307, when the left earphone and the right earphone are detected to be engaged, the bluetooth earphone may refuse to establish an SCO connection with the electronic device. Specifically, the bluetooth headset may send a rejection response of the SCO connection establishment request to the electronic device to reject establishment of the SCO connection with the electronic device. The reject reply of the SCO connection establishment request may be the LMP _ not _ accepted signaling mentioned in the foregoing fig. 4.

S308, after the Bluetooth headset refuses to establish the SCO connection, the electronic equipment can play conversation audio.

For example, when the left and right earphones of the bluetooth earphone are attracted, the bluetooth earphone refuses to establish the SCO connection with the electronic device, and when a call service arrives, the electronic device can play the call audio of the call service.

Stage 2A (S309-S310): the electronic device displays an indicator that the left and right earpieces of the bluetooth earpiece are in a separated state.

S309, when it is detected that the left earphone and the right earphone are separated, the bluetooth earphone may further send status indication information to the electronic device (e.g. a mobile phone), where the status indication information may be used to indicate that the left earphone and the right earphone are in a separated state. The status indication information may be referred to as second indication information.

Specifically, upon detecting that the left and right headsets are separated, the bluetooth headset may send the second indication information to the electronic device via an application level (profile) connection (e.g., HFP connection, A2DP connection).

After receiving the second indication information transmitted by the bluetooth headset in S309, the electronic device may display an indicator that the left and right headsets are separated S310. The indicator is the aforementioned second indicator. As shown in fig. 9A, the electronic device may specifically display a second indicator in the status bar.

The bluetooth headset may specifically send the second indication information to the electronic device (e.g., a mobile phone) when detecting that the left and right headsets are switched from the closed state to the open state. Therefore, the left earphone and the right earphone are separated from the attraction state, the electronic equipment can receive the state indication information and display the second indicator, and a user can immediately sense the state switching of the left earphone and the right earphone through the electronic equipment. The bluetooth headset may periodically transmit the indication information of the open/close states of the left and right headsets to the electronic device at a short period (for example, 5 milliseconds), not only when the open/close states of the left and right headsets are switched.

Stage 2B (S311-S316): the Bluetooth headset receives SCO connection with the electronic equipment and plays conversation audio.

S311, the electronic device may detect a user operation such as answering a call or making a call.

After detecting the user operation, the electronic device may send an SCO connection establishment request to the bluetooth headset S312.

S313, upon detecting that the left and right earphones are engaged, the bluetooth earphone may accept to establish an SCO connection with the electronic device. Specifically, the bluetooth headset may send an acceptance response of the SCO connection establishment request to the electronic device to accept establishment of the SCO connection with the electronic device. The SCO connection establishment request acceptance answer may be the LMP _ accepted signaling mentioned in the foregoing fig. 4.

And S314, the SCO connection is established.

Not limited to the SCO connection establishment initiated by the electronic device, the bluetooth headset may also initiate the SCO connection establishment upon detecting that the left and right headsets are separated. For example, when a user places a call using a bluetooth headset, the bluetooth headset may actively initiate an SCO connection setup. For the SCO connection establishment procedure, reference may be made to the related content of fig. 4, which is not described herein again.

S315, the electronic device can send the call audio data to the Bluetooth headset through SCO connection.

And S316, after receiving the call audio data from the electronic equipment, the Bluetooth headset can play the call audio.

Stage 2C (S317-S318): and disconnecting the SCO connection after the call is finished.

S317, the electronic device may detect that the call is ended.

In particular, a Phone application (Phone) on the electronic device may monitor for an end of a call, such as a user operation to hang up the Phone or other internal events.

S318, the electronic device may disconnect the SCO connection between the electronic device and the bluetooth headset. Specifically, the electronic device may disconnect (or remove) the SCO connection by sending a remove SCO connection establishment request to the bluetooth headset. The request to remove SCO connection establishment may be LMP _ remove _ SCO _ link _ req signaling mentioned in the foregoing fig. 4.

Not only when the call is ended, but also when the call is switched from the answering state of the Bluetooth headset to the answering state of the earphone and the loudspeaker of the electronic equipment, the SCO connection is disconnected.

It can be seen that the method provided by the second embodiment can realize that the usage scene of the bluetooth headset is rapidly switched along with the switching of the open and close states of the left and right headsets: when the left earphone and the right earphone are attracted, the Bluetooth earphone refuses to establish SCO connection with the electronic equipment, and the Bluetooth earphone is not used for playing the call audio temporarily; when the left earphone and the right earphone are separated, the Bluetooth earphone receives SCO connection with the electronic equipment, and the Bluetooth earphone is used for playing conversation audio.

The SCO connection is attached to the HFP connection, which can be used to transmit call control (e.g., listen, hang up, etc.) signaling. In order to further reduce the response delay, especially improve the response delay in a call scenario, the bluetooth headset can maintain HFP connection with the electronic device regardless of whether the left headset and the right headset are engaged or disengaged. When the bluetooth headset and the electronic device are paired and the bluetooth connection is established, the two may establish HFP connection. Regarding the HFP connection establishment process, reference may be made to the related content of fig. 5, which is not described herein again.

In the second embodiment, the bluetooth headset may have two usage states as shown in fig. 12: in the state 1, the left earphone and the right earphone are attracted, the Bluetooth earphone keeps HFP connection with the electronic equipment, and SCO connection with the electronic equipment is refused; state 2. left and right earphones are separated and the bluetooth earphone maintains HFP connection with the electronic device, accepts SCO connection with the electronic device. When the left earphone and the right earphone are switched from the attracting state to the separating state, the Bluetooth earphone and the electronic equipment can respond to a call requirement (such as a user calls a telephone) and quickly establish call audio connection on the premise that the Bluetooth connection is not disconnected, the response time delay of the Bluetooth earphone can be effectively reduced, and the purpose that the user uses the earphones by separating the left earphone and the right earphone is met.

EXAMPLE III

In this embodiment, above-mentioned embodiment one and above-mentioned embodiment two can combine to implement, and bluetooth headset also can be based on the actuation/the part state of left earphone and right earphone, and the connection status that two kinds of audios between the formula bluetooth headset are connected is inhaled to simultaneous control electronic equipment and magnetism under the circumstances that does not break bluetooth connection: media audio connection (e.g., A2DP connection), and connection status of conversation audio connection (disconnected or not).

Fig. 13 shows a wireless communication method provided in the third embodiment. In the method shown in fig. 13, a bluetooth connection (ACL connection) is established and maintained between the bluetooth headset and the electronic device. As shown in fig. 13, the method may include:

Stage 1A (S401-S402): the electronic equipment displays an indicator that the left earphone and the right earphone of the Bluetooth earphone are in the suction state. Specifically, reference may be made to the stage 1A in the first embodiment or the stage 1A in the second embodiment, which is not described herein again.

Stage 1B (S403): the bluetooth headset maintains HFP connection between it and the electronic device. If there is an existing A2DP connection between the Bluetooth headset and the electronic device, the A2DP connection is broken. Similarly, if there is an existing SCO connection between the bluetooth headset and the electronic device, the SCO connection is disconnected.

After the connection of A2DP is disconnected, if the playing of the media audio is not finished, the rest of the media audio can be played on the electronic equipment side. Specifically, reference may be made to stage 1B in the first embodiment, which is not described herein again.

Similarly, after the SCO connection is disconnected, if the call is not ended, the subsequent call audio can be played on the electronic device side. Specifically, reference may be made to stage 1B in embodiment two, which is not described herein again.

Stage 1C: when the left and right earphones are in the attraction state, the following two situations may exist in audio playing.

In case 1(S404-S407), when the left and right earphones are in the closed state, the electronic device determines that there is media audio to play. In this case, the electronic device may send an A2DP connection establishment request to the bluetooth headset to initiate an A2DP connection establishment. However, the bluetooth headset refuses to establish an A2DP connection with the electronic device. Therefore, the media audio can be routed to the electronic equipment side for playing, and the requirement that the user attracts the left earphone and the right earphone to pause the use of the Bluetooth earphone is met.

In case 2(S408-S411), when the left and right earphones are in the closed state, the electronic device detects a user operation to answer or make a call. In this case, the electronic device may send an SCO connection establishment request to the bluetooth headset to initiate SCO connection establishment. However, the bluetooth headset refuses to establish an SCO connection with the electronic device. Therefore, the call audio can be routed to the electronic equipment side for playing, and the requirement that the user separates the left earphone from the right earphone and then suspends the use of the Bluetooth earphone is met.

Stage 2A (S412): the bluetooth headset accepts an A2DP connection to be established with the electronic device. Specifically, reference may be made to the stage 1A in the first embodiment, which is not described herein again.

Stage 2B (S413-S414): the electronic device displays an indicator that the left and right earpieces of the bluetooth earpiece are in a separated state. Specifically, reference may be made to the stage 2B in the first embodiment or the stage 2A in the second embodiment, which is not described herein again.

And (2C): when the left and right earphones are in the separated state, the audio playing may have the following two cases.

Case 3(S415-S417), the electronic device determines that there is media audio to play while the left and right earphones are in the separated state. In this case, the electronic device may send an A2DP connection establishment request to the bluetooth headset to initiate an A2DP connection establishment. Accordingly, the bluetooth headset accepts the establishment of an A2DP connection with the electronic device. Therefore, the media audio can be routed to the Bluetooth headset side for playing, and the requirement that the user separates the left headset from the right headset and then uses the Bluetooth headset to play the media audio is met.

Case 4(S408-S411), when the left and right earphones are in the separated state, the electronic device detects a user operation of answering or making a call. In this case, the electronic device may send an SCO connection establishment request to the bluetooth headset to initiate SCO connection establishment. Accordingly, the bluetooth headset accepts the SCO connection with the electronic device. Therefore, the call audio can be routed to the Bluetooth headset side for playing, and the requirement that the user separates the left headset from the right headset to use the Bluetooth headset to play the media audio is met.

In the third embodiment, the bluetooth headset may have two usage states as shown in fig. 14: in the state 1, the left earphone and the right earphone are attracted, the Bluetooth earphone is disconnected or refuses to establish A2DP connection, maintains HFP connection between the Bluetooth earphone and the electronic equipment, and refuses to establish SCO connection with the electronic equipment; state 2. left and right headsets are separated, the bluetooth headset remains or accepts the A2DP connection, maintains its HFP connection with the electronic device, accepts the SCO connection with the electronic device. When the left earphone and the right earphone are switched from the attracting state to the separating state, the Bluetooth earphone and the electronic equipment can respond to audio playing requirements (such as conversation, music listening and the like) on the premise that the Bluetooth connection is not disconnected to quickly establish media audio connection and conversation audio connection, the response time delay of the Bluetooth earphone can be effectively reduced, and the purpose that a user uses the earphones by separating the left earphone and the right earphone is met.

It can be seen that, according to the method provided in the third embodiment, on the premise of not disconnecting the bluetooth connection and the HFP connection, the connection states of the media audio connection (for example, A2DP connection) and the call audio connection (for example, SCO connection) can be controlled based on the open/close states of the left and right earphones of the bluetooth earphones. When the left earphone and the right earphone are switched from the attraction state to the separation state, the Bluetooth earphone quickly establishes audio connection according to the actual audio playing requirement (if media audio needs to be played), the response time delay of the Bluetooth earphone can be effectively reduced, and the purpose that a user uses the earphones by separating the left earphone and the right earphone is met.

In the wireless communication method provided in the foregoing embodiments, the left earphone may be summarized as the first audio output device, and the right earphone may be summarized as the second audio output device. The wireless communication method provided by the above embodiments is not limited to be performed by a bluetooth headset, but may be performed by other types of audio output devices, such as a pair of bluetooth speakers. Wherein, the left earphone and the right earphone can be replaced by a left sound channel sound box and a right sound channel sound box in a pair of Bluetooth sound boxes respectively. Or the left earphone and the right earphone can be replaced by sound boxes with other two sound channels. The left sound channel sound box and the right sound channel sound box can be internally provided with magnetic components, and the connection state of audio connection can be controlled based on the opening and closing state between the left sound channel sound box and the right sound channel sound box.

In addition, the embodiment of the application also provides a wireless communication method, and on the premise of not disconnecting the bluetooth connection and the A2DP connection, the media audio is controlled to be played by the bluetooth headset or the electronic device based on the opening and closing states of the left and right earphones of the bluetooth headset. Specifically, if the left and right earphones are separated, the media audio is played by the Bluetooth earphone. Specifically, after the bluetooth headset receives the media audio data from the electronic device through the A2DP connection, the media audio can be played. If the left earphone and the right earphone are attracted, the media audio is played by the electronic equipment. Specifically, the bluetooth headset may send feedback to the electronic device rejecting playing audio after receiving some or all of the media audio data from the electronic device via the A2DP connection. After receiving this feedback from the bluetooth headset, the electronic device may play media audio.

An exemplary electronic device 200 provided in an embodiment of the present application is described below. The electronic device 200 may be implemented as the first audio output device mentioned in the above embodiments, and may be the electronic device 101 in the wireless audio system 100 shown in fig. 1A or the electronic device 201 in the wireless audio system 200 shown in fig. 2A.

Wherein:

both the first audio output device and the second audio output device may be integrated with a sensor 306, a microphone 307 and an electric/acoustic transducer 308. If the audio recipient device 300 is a neck-worn bluetooth headset, the audio recipient device 300 may also include drive-by-wire. The processor 302, memory 303, bluetooth communication processing module 304, power supply 305 may be integrated in line control. If the audio recipient device 300 is a TWS Bluetooth headset, both the first audio output device and the second audio output device may also be integrated with a processor 302, a memory 303, a Bluetooth communication processing module 304, and a power supply 305.

Processor 302 may be used to read and execute computer readable instructions. In particular implementations, processor 302 may primarily include a controller, an operator, and registers. The controller is mainly responsible for instruction decoding and sending out control signals for operations corresponding to the instructions. The arithmetic unit is mainly responsible for executing fixed-point or floating-point arithmetic operation, shift operation, logic operation and the like, and can also execute address operation and conversion. The register is mainly responsible for storing register operands, intermediate operation results and the like temporarily stored in the instruction execution process. In a Specific implementation, the hardware architecture of the processor 302 may be an Application Specific Integrated Circuits (ASIC) architecture, an MIPS architecture, an ARM architecture, or an NP architecture, for example.

In some embodiments, the processor 302 may be configured to parse signals received by the bluetooth communication processing module 304, such as signals encapsulating audio data, content control messages, flow control messages, and so forth. The processor 302 may be configured to perform corresponding processing operations according to the parsing result, such as driving the electric/acoustic converter 308 to start or pause or stop converting the audio data into sound, and so on.

In some embodiments, the processor 302 may also be configured to generate signals sent out by the bluetooth communication processing module 304, such as bluetooth broadcast signals, beacon signals, and audio data converted from collected sounds.

Memory 303 is coupled to processor 302 for storing various software programs and/or sets of instructions. In particular implementations, memory 303 may include high speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid state storage devices. The memory 303 may store an operating system, such as an embedded operating system like uCOS, VxWorks, RTLinux, etc. The memory 303 may also store communication programs that may be used to communicate with the electronic device 200, one or more servers, or additional devices.

The Bluetooth (BT) communication processing module 304 may receive signals transmitted by other devices, such as the electronic device 200, such as scanning signals, broadcast signals, signals encapsulating audio data, content control messages, flow control messages, and so forth. The Bluetooth (BT) communication processing module 304 may also transmit signals such as broadcast signals, scanning signals, signals encapsulating audio data, content control messages, flow control messages, and the like.

The power supply 305 may be used to power the processor 302, memory 303, bluetooth communication processing module 304, sensors 306, electric/acoustic transducer 308, and other internal components.

The sensor 306 may be used to detect whether the first audio output device and the second audio output device are engaged together. The sensor may be a hall sensor, a proximity light sensor, or the like. The sensor may be referred to as a first sensor. If the first audio output device and the second audio output device are attracted together, the first audio output device and the second audio output device can be called to be in an attraction state; otherwise, the first audio output device and the second audio output device may be said to be in a separated state.

The microphone 307 may be used to collect sounds, such as the voice of a user speaking, and may output the collected sounds to the electric/acoustic transducer 308, so that the electric/acoustic transducer 308 may convert the sounds collected by the microphone 307 into audio data.

The electric/acoustic transducer 308 may be used to convert sound into an electrical signal (audio data), for example, convert sound collected by the microphone 307 into audio data, and may transmit the audio data to the processor 302. In this way, the processor 302 may trigger the Bluetooth (BT) communication processing module 304 to transmit the audio data. The electric/acoustic transducer 308 may also be used to convert electrical signals (audio data) into sound, for example, audio data output by the processor 302 into sound. The audio data output by the processor 302 may be received by a Bluetooth (BT) communication processing module 304.

In some implementations, the processor 302 may implement Host in a bluetooth protocol framework and the Bluetooth (BT) communication processing module 304 may implement controller in a bluetooth protocol framework, communicating between them via HCI. For example, the functionality of the bluetooth protocol framework is distributed over two chips.

In other embodiments, the processor 302 may implement Host and controller in the Bluetooth protocol framework. For example, all functions of the bluetooth protocol framework are placed on one chip, that is, the host and the controller are placed on the same chip, and since the host and the controller are both on the same chip, there is no necessity for a physical HCI, and the host and the controller interact directly through an application programming interface API.
