[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] Embodiment 1

[0036] The present application embodiment provides a Bluetooth device, Figure 1 A schematic diagram of the structure of an optional Bluetooth device provided in an embodiment of the present application, such as Figure 1 As shown, the Bluetooth device 11 includes:

[0037] The optical communication module 111 is used to receive optical signals and process the optical signals into electrical signals;

[0038] A processor 112, configured to parse the electrical signal into data; and

[0039] The Bluetooth module 113 is used to receive data.

[0040] At present, commonly used Bluetooth devices 11 usually use Bluetooth technology for communication. However, the frequency band used by Bluetooth technology is easily monitored by eavesdroppers, which threatens security. In addition, when the Bluetooth device 11 encounters some more complex application scenarios during use, pairing errors and other faults may occur.

[0041] In order to solve the above-mentioned fault, an optical communication module 111 is set in the Bluetooth device 11 provided in the embodiment of the present application. The optical communication module 111 mainly uses optical communication technology, wherein optical communication technology refers to a communication method that uses light waves as information carriers to directly transmit optical signals in the air. Here, it should be noted that the light waves here can be visible light waves or non-visible light waves, for example, infrared light. The embodiment of the present application does not make specific limitations on this.

[0042] Specifically, the optical communication module 111 receives optical signals and performs photoelectric conversion on the optical signals, so that the optical signals can be converted into electrical signals. The processor 112 then analyzes the electrical signals to obtain data, so that the Bluetooth module 113 can receive the data and complete the data communication with the help of more information.

[0043] Among them, the above-mentioned Bluetooth device 11 can be a Bluetooth headset component, augmented reality (AR, Augmented reality) / virtual reality (VR, Virtual Reality) glasses and watches, etc. Here, the embodiment of the present application does not make specific limitations on this.

[0044] Furthermore, in order to realize the functions of receiving optical signals, photoelectric conversion and signal processing, the optical communication module 111 may include, in an optional embodiment:

[0045] Light receiving module, photoelectric conversion module and signal processing module; wherein,

[0046] The optical receiving module is used to receive optical signals;

[0047] The photoelectric conversion module is used to perform photoelectric conversion on the optical signal to obtain an electrical signal after photoelectric conversion;

[0048] The signal processing module is used to process the electrical signal and transmit the processed electrical signal to the processor.

[0049] In order to achieve the ability to receive optical signals, in an optional embodiment, the optical receiving module includes an optical window.

[0050] That is to say, the optical receiving module is used to receive the optical signal. For example, an optical window is used to receive the optical signal. The optical window is set on the surface of the Bluetooth device. The optical window may include a filter, a lens group and a polarizer. The filter can be used to filter the optical signal, allowing light of a specific band in the optical signal to pass through and filtering out light of other bands. The lens group is used to adjust the light of the specific band allowed to pass through to achieve the purpose of focusing. The polarizer is used to pass light in a vibration direction, that is, to allow light in a vibration direction of the focused optical signal to pass through. In this way, the required optical signal can be obtained.

[0051] In order to implement signal processing of the electrical signal, in an optional embodiment, the signal processing module performs signal processing on the electrical signal, including: the signal processing module performs filtering, amplification, demodulation, and sampling processing on the electrical signal.

[0052] Among them, the photoelectric conversion module can realize the photoelectric conversion of the optical signal through a photodiode or a photoresistor to obtain the optical signal after photoelectric conversion. The signal processing module may include a filter, an amplifier modem, etc. to realize the filtering, amplification, modulation or demodulation and sampling of the optical signal after photoelectric conversion. Here, it can be set according to the actual situation. For example, when the signal is weak, it needs to be amplified; when the signal is mixed with noise, it needs to be filtered; when the frequency is not suitable for transmission, it needs to be modulated or demodulated; when the frequency encounters distortion, it needs to be equalized; when there are many types of signals, they need to be identified.

[0053] In this way, a series of processing of the optical signal can be realized through the optical receiving module, the photoelectric conversion module and the signal processing module to obtain an electrical signal for processing by the processor of the Bluetooth device.

[0054] In an optional embodiment, the above-mentioned Bluetooth device is a Bluetooth headset.

[0055] Furthermore, as a common Bluetooth device, the Bluetooth headset mainly uses the Bluetooth technology for data communication. That is to say, an optical communication module is added to the Bluetooth headset, and the optical communication module is connected to the processor of the Bluetooth headset. Then, when the optical communication module of the Bluetooth headset receives the optical signal, it obtains an electrical signal through photoelectric conversion and signal processing, so that the processor receives the electrical signal. In this way, in addition to transmitting data through Bluetooth technology, the Bluetooth headset can also transmit data with the outside world through the optical communication module. In this way, the Bluetooth headset can use communication modules with two paths for data communication, which helps to expand the functions of the Bluetooth headset.

[0056] Figure 2 A schematic diagram of the structure of an optional Bluetooth headset example provided in an embodiment of the present application, such as Figure 2 As shown, the Bluetooth headset 22 may include: a central processing unit (CPU) 221 , a Bluetooth module 222 and a visible light communication module 223 .

[0057] That is to say, Figure 2The Bluetooth headset adopts visible light communication technology, wherein the visible light communication module 223 and the Bluetooth module 222 are respectively connected to the CPU 221, and the visible light communication module 223 includes an optical window 2231, a photoelectric sensor 2232 and a signal processing module 2233, wherein the optical window 2231 is used to receive visible light, and may have optical functions such as focusing, filtering and polarization; the optical sensor 2232 is used to convert the optical signal into an electrical signal; the signal processing module 2233 is used to filter, amplify, demodulate, sample and other functions on the obtained electrical signal, and output a digital signal.

[0058] With respect to the above-mentioned Bluetooth headset additionally equipped with an optical communication module, accordingly, the embodiment of the present application further provides a Bluetooth headset compartment paired with the Bluetooth headset described in one or more of the above-mentioned embodiments. Figure 3 A schematic diagram of the structure of an optional Bluetooth headset compartment provided in an embodiment of the present application, such as Figure 3 As shown, the Bluetooth headset compartment 33 may include:

[0059] Controller 331; and

[0060] Light emitting component 332;

[0061] Among them, the controller 331 is used to modulate the light signal and turn on the light-emitting component 332 when the lid of the Bluetooth headset compartment 33 is closed, so as to send the light signal to the Bluetooth headset, and turn off the light-emitting component 332 when it is determined that the lid of the Bluetooth headset compartment is open.

[0062] Specifically, a light-emitting component 332 is provided in the Bluetooth headset compartment 33, and the controller 331 is capable of modulating an optical signal and controlling the light-emitting component 332 to open or close according to the state of the compartment cover of the Bluetooth headset compartment. In this way, the Bluetooth headset compartment 33 can perform optical communication with the Bluetooth headset when it is closed, thereby avoiding the risk of information leakage during communication.

[0063] In order to realize optical communication between the earphone compartment and the Bluetooth headset, the light-emitting component can be set on the surface of the placement hole of the Bluetooth headset in the earphone compartment, or the light-emitting component can be set inside the earphone compartment. The light can be emitted through a light guide column or a transparent material, so that the Bluetooth headset can receive the modulated light signal. In this way, when the earphone compartment needs to send data to the Bluetooth headset, the controller modulates and emits the light wave so that the Bluetooth headset can receive the light signal.

[0064] In addition, in order to ensure the security of data between the Bluetooth headset and the Bluetooth headset compartment, the controller needs to judge the status of the compartment cover of the Bluetooth headset compartment. When the compartment cover is open, in order to ensure the privacy of the light wave transmission, the controller turns off the light-emitting component. When the compartment cover is closed, the Bluetooth headset is placed in the placement hole of the Bluetooth headset, and the controller turns on the light-emitting component so that the Bluetooth headset can receive data from the headset compartment inside the closed headset compartment. The data can be some encrypted information. Since the headset compartment is closed, the light waves emitted by the light-emitting component are confined to the inside of the headset compartment, so that the security of the transmitted data is guaranteed.

[0065] In order to realize the function of optical communication, in an optional embodiment, the light-emitting component 332 is arranged in the Bluetooth headset compartment.

[0066] Specifically, the light-emitting component is set in the Bluetooth headset compartment, so that the data transmission of confidential information between the Bluetooth headset compartment and the Bluetooth headset can be better realized.

[0067] Furthermore, when setting the light-emitting component in the above-mentioned Bluetooth headset compartment, it can be set according to the specific structure of the Bluetooth headset compartment. In an optional embodiment, the Bluetooth headset compartment includes a first optical compartment and a second optical compartment that are independent of each other, each of which is used to store a Bluetooth headset, and the first optical compartment and the second optical compartment respectively include a first light-emitting component and a second light-emitting component.

[0068] Specifically, when the Bluetooth headset compartment includes two independent optical compartments, wherein the two optical compartments are respectively the first optical compartment and the second optical compartment, and the two optical compartments are respectively used to store a Bluetooth headset, here, the first light-emitting component is arranged in the first optical compartment, and the second light-emitting component is arranged in the second optical compartment. In addition, in an optional embodiment, the Bluetooth headset compartment includes an optical compartment, which is used to store two Bluetooth headsets, and the optical compartment includes a light-emitting component.

[0069] When the Bluetooth headset has only one optical compartment, the light-emitting component is disposed in the optical compartment. This facilitates the light-emitting component to send optical signals to the Bluetooth headset.

[0070] Here, it should be noted that, for the Bluetooth headset compartment in which the two optical compartments are respectively provided with light-emitting components, in an optional embodiment, the optical signal modulated by the controller for the first light-emitting component is the same as the optical signal modulated for the second light-emitting component.

[0071] Here, when the optical signals modulated by the controller for the first light-emitting component and the second light-emitting component are the same, the optical signals received by the Bluetooth headset are the same. In an optional embodiment, the optical signal modulated by the controller for the first light-emitting component is different from the optical signal modulated by the controller for the second light-emitting component.

[0072] That is to say, the controller modulates different light signals for different light-emitting components, so that the first light-emitting component and the corresponding Bluetooth headset can communicate data independently, and the second light-emitting component and the corresponding Bluetooth headset can also communicate data independently. In this way, different information can be transmitted to each other, further expanding the data transmission function between the Bluetooth headset and the Bluetooth headset compartment.

[0073] In an optional embodiment, the optical signal includes information that needs to be kept confidential.

[0074] When the Bluetooth headset communicates with the Bluetooth headset compartment through optical signals, the compartment cover of the Bluetooth headset compartment is closed, which is conducive to the transmission of optical signals containing information that needs to be kept confidential.

[0075] Figure 4 A schematic diagram of the structure of an optional Bluetooth headset compartment example provided in an embodiment of the present application, such as Figure 4 As shown, the Bluetooth headset compartment 44 may include: a control module 441, two light sources 442, a headset (left) 443 and a headset (right) 444, wherein the headset (left) 443 and the headset (right) 444 each include a visible light communication module (VLC, Visible Light Communication), wherein: Figure 4 The Bluetooth headset compartment is in an open state, VLC of headset (left) 443 and headset (right) 444 is not working, and the headset is placed in the placement hole for charging or taken out from the placement hole.

[0076] Figure 5 A schematic diagram of the structure of another optional Bluetooth headset compartment example provided in an embodiment of the present application, such as Figure 5 As shown, the Bluetooth headset compartment 55 may include: a headset compartment cover 551, a control module 552, two light sources 553, a headset (left) 554 and a headset (right) 555, wherein the headset (left) 553 and the headset (right) 554 each include a VLC, wherein: Figure 5 When the Bluetooth headset compartment is in a closed state, the VLC of the headset (left) 553 and the headset (right) 554 can work. Visible light information is emitted through the light source 553 and is received and demodulated by the visible light communication module of the Bluetooth headset. This information may be some information required by the headset that does not want to be eavesdropped by the outside world. Since the compartment cover is in a closed state, the light cannot leak out and be sniffed.

[0077] Regarding the out-of-band communication method between the earphone pod and the Bluetooth headset involved in this example, the physical isolation of the earphone pod avoids the leakage of light through this out-of-band communication method. It can be applied to the one-way transmission of some private data and can improve the transmission efficiency, such as the related key transmission and authentication in the over-the-air (OTA) upgrade.

[0078] An embodiment of the present application provides a Bluetooth device, which includes: an optical communication module for receiving optical signals and processing the optical signals into electrical signals, a processor for parsing the electrical signals into data, and a Bluetooth module for receiving data; that is, in an embodiment of the present application, by setting an optical communication module in the Bluetooth device, the Bluetooth device can communicate through optical signals, so that in addition to being able to use the original Bluetooth module, the Bluetooth device can also use the optical communication module to achieve the two-way communication function of optical communication and Bluetooth communication. In this way, with the help of the small size and limitable characteristics of the optical communication module, the Bluetooth device can use the optical communication module to communicate with the outside world to obtain more information, so as to improve the processing capability of the Bluetooth device, thereby reducing the transmission failure rate of the Bluetooth device.

[0079] Based on the same inventive concept, an embodiment of the present application provides a communication method for a Bluetooth device described in one or more of the above embodiments. Figure 6 A flow chart of an optional communication method provided in an embodiment of the present application is as follows: Figure 6 As shown, the above communication method may include:

[0080] S601: receiving an optical signal from an electronic device, the optical signal including a region identifier corresponding to the electronic device;

[0081] S602: Determine the area where the Bluetooth device is located according to the area identifier;

[0082] S603: receiving a broadcast signal from at least one Bluetooth audio source;

[0083] S604: When the area of ​​the Bluetooth audio source broadcasting the signal matches the area where the Bluetooth device is located, establish a connection with the Bluetooth audio source.

[0084] Specifically, the above-mentioned electronic device is an electronic device that modulates an optical signal, and the optical signal contains an identification of the area where the electronic device is located. In this way, after receiving the optical signal emitted by the electronic device, the Bluetooth device can determine the area where it is currently located. Then, when the Bluetooth device receives a broadcast signal from at least one Bluetooth audio source, the Bluetooth device determines whether the area of ​​the Bluetooth audio source of the broadcast signal matches the area where the Bluetooth device is located. If they match, the Bluetooth device establishes a connection with the Bluetooth audio source.

[0085] In an optional embodiment, when the area of ​​the Bluetooth audio source broadcasting the signal matches the area where the Bluetooth device is located, the connection with the currently paired device is maintained.

[0086] Specifically, when the Bluetooth device currently has a paired device, it determines whether the area of ​​the Bluetooth sound source that receives the broadcast signal matches the area where the Bluetooth device is located. If it matches, it means that the area identifier of the current paired device matches the Bluetooth device, so the current connection continues.

[0087] In an optional embodiment, the Bluetooth device moves to another area, and the method further includes:

[0088] receiving an optical signal from another electronic device, the optical signal including a region identifier corresponding to the other electronic device;

[0089] According to the area identifier, another area where the Bluetooth device is located is determined.

[0090] Specifically, when the Bluetooth device moves to another area and receives an optical signal from another electronic device, the optical signal includes an area identifier corresponding to the other electronic device. At this time, the area where the Bluetooth device is located is determined according to the area identifier. In other words, the optical communication module can determine the area where it is located based on the received optical signal.

[0091] In an optional embodiment, when the area of ​​the Bluetooth audio source broadcasting the signal does not match another area where the Bluetooth device is located, the current connection is disconnected.

[0092] That is, when the Bluetooth device moves to another area, it is determined whether the area of ​​the Bluetooth audio source broadcasting the signal matches the other area where the Bluetooth device is located. If not, it means that the current connection needs to be updated, so the current connection is disconnected.

[0093] In an optional embodiment, a connection is established with another Bluetooth audio source, and the area of ​​the other Bluetooth audio source that broadcasts the signal matches the area where the Bluetooth device is located.

[0094] After disconnecting the current connection, a connection is established with another Bluetooth audio source, so that the area of ​​the other audio source broadcasting the signal is matched with the area where the Bluetooth device is located.

[0095] It should be noted that the Bluetooth audio source includes at least one of the following: a Bluetooth speaker, a Bluetooth TV, a computer, and a mobile phone.

[0096] The communication method described in one or more of the above embodiments is described below with examples.

[0097] Figure 7 The present invention provides an example of a flow chart of an optional communication system, such as Figure 7As shown, the communication system may include: a room / place 71, a Bluetooth audio device 72 and a visible light communication lamp 73 in the room / place 71, a room / place 74, a Bluetooth audio device 75 and a visible light communication lamp 76 in the room / place 74, and the above communication method may include:

[0098] Visible light communication lamps 73 and visible light communication lamps 76 are placed in different rooms, and the light emitted by the visible light communication lamps 73 and visible light communication lamps 76 modulates relevant room information;

[0099] The user enters the room / place 71 with headphones, and the headphones receive the visible light communication signal emitted by the visible light communication lamp 73 to confirm the room information.

[0100] The earphones carried by the user receive several Bluetooth audio source broadcast signals in room / place 71, find the signal corresponding to room / place 71 and connect.

[0101] The headset carried by the user leaves room / place 71 and enters room / place 74, and the headset receives the visible light communication signal emitted by the visible light communication lamp 76 to confirm the room information.

[0102] The headphones carried by the user receive several Bluetooth audio source broadcast signals in room / place 74. If the connection between the headphones and the Bluetooth audio source device 72 is not disconnected, the headphones find that the room number does not match the connected audio source, disconnect the current connection, find the signal of room / place 74 from the broadcast and reconnect. If the connection between the headphones and the Bluetooth audio source device 75 is disconnected, the user finds the signal of room / place 74 from the broadcast and connects.

[0103] It should be noted that the above-mentioned visible light communication lamps can be generalized into visible light communication light sources, and can also form a whole with Bluetooth audio source devices. For example, Bluetooth TV is a visible light communication light source that can emit modulated light. It emits light of a specific wavelength through the TV screen and communicates out-of-band with Bluetooth headsets.

[0104] This example is used for indoor auxiliary positioning and dynamic identification and switching of audio scenes. It realizes the need to divide the Bluetooth connection domain by physical room as the boundary, avoiding the problem of inaccurate segmentation of physical boundaries caused by wall reflection, absorption, multipath effect, etc. when general indoor positioning uses wireless signals for positioning. For example, it can be used in indoor applications such as automatic explanation in museum exhibition halls and smart homes.
