[0070] <Method Example>

[0071] Figure 2 It is a flow chart of a positioning method of an electronic device according to an embodiment of the present invention. The method is applied to headphones, and the headphones include a master headphone 2000 and a slave headphone 3000. When the positioning function of the electronic device 1000 is not turned on, the master headphone is connected to the electronic device for communication, and the slave headphone is connected to the master headphone for communication. When the positioning function of the electronic device 1000 is turned on, the electronic device is connected to the master headphone and the slave headphone for communication respectively, the electronic device 1000 transmits a Bluetooth signal, and the master headphone 2000 and the slave headphone 3000 receive the Bluetooth signal transmitted by the electronic device 1000 respectively. In addition, the master headphone 2000 can also send the received Bluetooth signal to the slave headphone 3000, that is, the slave headphone 3000 also receives the Bluetooth signal forwarded via the master headphone 2000.

[0072] according to Figure 2 As shown, the positioning method of the electronic device in this embodiment may include the following steps S2100 to S2400:

[0073] Step S2100: The master earphone determines a first relative position of the electronic device relative to the master earphone according to a Bluetooth signal transmitted by the electronic device and received by the master earphone.

[0074] In this embodiment, the main earphone can determine the distance between the main earphone and the electronic device according to the Bluetooth signal, and can also determine the propagation direction of the Bluetooth signal between the main earphone and the electronic device according to the Bluetooth signal.

[0075] There are various ways to determine the distance between the host headset and the electronic device based on the Bluetooth signal.

[0076] In one example, the first distance radius between the main headset and the electronic device can be determined based on the signal attenuation model and the RSSI (Received Signal Strength Indicator) value. Among them, the RSSI value is an indicator to measure the strength of the Bluetooth signal, and its value reflects the attenuation of the Bluetooth signal during the transmission process. The signal attenuation model reflects the relationship between the Bluetooth signal strength and the transmission distance. Therefore, by measuring the signal strength (RSSI value) of the Bluetooth signal, and then using the signal attenuation model, the RSSI value can be converted into a distance value, and the distance value is the first distance radius.

[0077] In another example, the distance may be determined by Channel Sounding (CS), which estimates the distance by measuring the phase difference between radio signals and / or the flight time of radio signals.

[0078] Those skilled in the art should understand that the method for determining the distance between the primary earphone and the electronic device is not specifically limited here.

[0079] Exemplarily, the method of determining the propagation direction of the Bluetooth signal between the main headset and the electronic device based on the Bluetooth signal can be through the angle of arrival (AoA) technology. In the AoA method, the main headset acts as a receiving device and receives signals from the electronic device through multiple antennas arranged in an array. Due to the distance between the antennas of the antenna array, there will be slight differences in the time it takes for the Bluetooth signal to arrive at each antenna, and this time difference leads to a difference in phase. By measuring these phase differences, the main headset can calculate the angle of arrival of the Bluetooth signal, thereby determining the orientation of the electronic device relative to the main headset.

[0080] In some embodiments, in step S2100, the master earphone determines the first relative position of the electronic device with respect to the master earphone according to the Bluetooth signal transmitted by the electronic device and received by the master earphone, including: steps S2101 to S2103.

[0081] Step S2101: Determine a first distance radius between the electronic device and the master headset according to the signal strength of the Bluetooth signal received by the master headset.

[0082] In this embodiment, the Bluetooth signal strength indication (RSSI, Received Signal Strength Indication) is based on the fact that when the Bluetooth signal propagates in the air, its strength will attenuate as the distance increases. This attenuation usually conforms to a certain law, which can be reflected by a model, such as a free space path loss model or a multipath fading model. On this basis, the main headset can estimate the first distance radius between the electronic device and the main headset by measuring the received Bluetooth signal strength.

[0083] It should be noted that the position of the electronic device estimated by RSSI technology can be located at any position on the circumference of the first distance radius from the main earphone. If the specific position of the electronic device needs to be determined, the direction of the electronic device relative to the main earphone also needs to be determined.

[0084] Step S2102: determining a first propagation direction of the Bluetooth signal between the master headset and the electronic device according to a time delay difference of the master headset receiving the Bluetooth signal.

[0085] In this embodiment, an antenna array is provided in the master earphone. When the master earphone receives a Bluetooth signal transmitted by an electronic device, there will be slight differences in the time it takes for the Bluetooth signal to reach each antenna. This time difference leads to a difference in phase. The phase difference and time difference can be collectively referred to as a delay difference. Therefore, the master earphone can calculate the arrival angle of the Bluetooth signal by measuring these phase differences or time differences. The arrival angle refers to the angle between the plane where the master earphone is located and the propagation direction of the Bluetooth signal, indicating the orientation of the electronic device relative to the master earphone, that is, the first propagation direction.

[0086] Step S2103: determining a first relative position of the electronic device relative to the primary earphone according to the first distance radius and the first propagation direction.

[0087] For example, the first distance radius between the electronic device and the primary earphone is L1, and the first propagation direction is α1, so the first relative position of the electronic device relative to the primary earphone can be determined.

[0088] Step S2200: The slave earphone determines a second relative position of the electronic device with respect to the slave earphone according to the Bluetooth signal transmitted by the electronic device and received by the slave earphone.

[0089] In this embodiment, the Bluetooth signal transmitted by the electronic device and received by the slave earphone is a Bluetooth signal directly sent by the electronic device to the slave earphone, rather than a Bluetooth signal forwarded via the master earphone.

[0090] The slave earphone can determine the distance between the slave earphone and the electronic device according to the Bluetooth signal, and can also determine the propagation direction of the Bluetooth signal between the slave earphone and the electronic device according to the Bluetooth signal.

[0091] In some embodiments, in step S2200, the slave earphone determines the second relative position of the electronic device with respect to the slave earphone according to the Bluetooth signal transmitted by the electronic device and received by the slave earphone, including steps S2201 to S2203.

[0092] Step S2201: Determine a second distance radius between the electronic device and the slave earphone according to the signal strength of the Bluetooth signal received by the slave earphone.

[0093] In this embodiment, the slave earphone receives the Bluetooth signal transmitted by the electronic device, and determines the second distance radius between the electronic device and the slave earphone by using the RSSI value. The method of determining the second distance radius by using the RSSI value is the same as the method of determining the first distance radius by using the RSSI value of the master earphone, which will not be repeated here.

[0094] Step S2202: determining a second propagation direction of the Bluetooth signal between the electronic device and the slave earphone according to the time delay difference of receiving the Bluetooth signal from the slave earphone.

[0095] In this embodiment, the slave earphone determines the arrival angle of the Bluetooth signal based on the delay difference (time difference or phase difference) of the Bluetooth signal transmitted by the electronic device and received by each antenna in the antenna array of the earphone. The arrival angle refers to the angle between the plane where the slave earphone is located and the propagation direction of the Bluetooth signal, indicating the orientation of the electronic device relative to the slave earphone, that is, the second propagation direction.

[0096] It should be noted that the method in which the slave earphone determines the second propagation direction through the AoA technology is the same as the method in which the master earphone determines the first propagation direction through the AoA technology, which will not be elaborated here.

[0097] Step S2203: Determine a second relative position of the electronic device with respect to the slave earphone according to the second distance radius and the second propagation direction.

[0098] For example, the second distance radius between the electronic device and the slave earphone is L2, and the second propagation direction is α2, so the first relative position of the electronic device relative to the master earphone can be determined.

[0099] Step S2300: Determine whether a first spatial position corresponding to the first relative position and a second spatial position corresponding to the second relative position overlap.

[0100] In this embodiment, the execution subject of step S2300 can be a slave headset or a master headset. When the execution subject of this step is a slave headset, after determining the first relative position of the electronic device relative to the master headset, the master headset can send the first relative position information to the slave headset for use by the slave headset when executing step S2300.

[0101] The first spatial position may be determined according to the spatial position of the main earphone and the first relative position of the electronic device relative to the main earphone.

[0102] The second spatial position may be determined according to the spatial position of the slave earphone and a second relative position of the electronic device relative to the slave earphone.

[0103] The spatial position of the master earphone and the spatial position of the slave earphone can be determined by a positioning device of the earphone.

[0104] The position coordinates of the first spatial position and the position coordinates of the second spatial position are equal, that is, it is considered that the first spatial position and the second spatial position coincide with each other.

[0105] In some embodiments, the headphone distance between the master earphone and the slave earphone can be estimated based on the first relative position and the second relative position, and then whether the first spatial position and the second spatial position coincide with each other can be determined based on whether the reference headphone distance between the master earphone and the slave earphone is equal to the estimated headphone distance.

[0106] Based on this, determining in step S2300 whether the first spatial position corresponding to the first relative position and the second spatial position corresponding to the second relative position overlap includes: steps S2301 to S2304.

[0107] Step S2301: Determine a reference earphone distance between the master earphone and the slave earphone according to the Bluetooth signal sent by the master earphone and received by the slave earphone.

[0108] In this embodiment, the slave earphone may determine a reference earphone distance between the master earphone and the slave earphone based on the signal strength or signal arrival time of the received Bluetooth signal sent by the master earphone, which is recorded as L3.

[0109] Those skilled in the art should understand that the method of determining the transmission distance based on the signal strength or the signal arrival time is well known in the art and will not be elaborated here.

[0110] In some embodiments, determining a reference earphone distance between the master earphone and the slave earphone according to the Bluetooth signal sent by the master earphone and received by the slave earphone comprises:

[0111] A reference earphone distance is determined according to the signal strength of the Bluetooth signal sent by the master earphone and received by the slave earphone.

[0112] In this embodiment, the method of determining the reference earphone distance based on the signal strength of the Bluetooth signal sent by the main earphone received from the earphone is the same as the method of determining the first distance radius in step S2201 and the method of determining the second distance radius in step S2301, which will not be repeated here.

[0113] Step S2302: Determine an estimated headphone distance between the master headphone and the slave headphone according to the first relative position and the second relative position.

[0114] In this embodiment, the first relative position of the electronic device relative to the master earphone may be a position at a distance of L1 from the master earphone and at an angle of α1 to the plane where the master earphone is located. The second relative position of the electronic device relative to the slave earphone may be a position at a distance of L2 from the slave earphone and at an angle of α2 to the plane where the slave earphone is located. Based on the above L1, α1, L2, and α2, the earphone distance between the master earphone and the slave earphone is estimated. The estimated earphone distance can be expressed as: L1*cosα1+L2*cosα2.

[0115] Step S2303: When the reference earphone distance is equal to the estimated earphone distance, determine that the first spatial position and the second spatial position overlap.

[0116] In this embodiment, the positioning is considered to be accurate if the first spatial position and the second spatial position coincide with each other.

[0117] Step S2304: When the reference earphone distance is not equal to the estimated earphone distance, determine that the first spatial position and the second spatial position do not overlap.

[0118] After executing step S2300, step S2400 is executed, in which, when the first spatial position and the second spatial position coincide with each other, at least one of the first relative position and the second relative position is used as the actual position of the electronic device.

[0119] For example, the first relative position of the electronic device relative to the main earphone is taken as the actual position of the electronic device.

[0120] In some embodiments, after executing step S2300, the method further includes: steps S3100 to S3300.

[0121] Step S3100: When the first spatial position and the second spatial position do not overlap, the parameter value in the estimated headphone spacing is corrected according to the reference headphone spacing so that the estimated headphone spacing is equal to the reference headphone spacing.

[0122] In this embodiment, according to the reference headphone distance L3, at least one parameter value of the parameter values ​​L1, α1, L2, α2 in the estimated headphone distance is adjusted to make the estimated headphone distance L1*cosα1+L2*cosα2 equal to the reference headphone distance L3.

[0123] In some examples, adjusting the parameter values ​​in the estimated headphone distance may be adjusting the distance values ​​L1, L2, or adjusting the angle values ​​α1, α2, or adjusting the distance values ​​L1, L2 and the angle values ​​α1, α2 simultaneously.

[0124] Among them, L1 and α1 are parameter values ​​corresponding to the first relative position, and L2 and α2 are parameter values ​​corresponding to the second relative position, that is, the parameter values ​​for estimating the earphone distance include the parameter values ​​corresponding to the first relative position and the second relative position.

[0125] The estimated earphone distance is the earphone distance between the master earphone and the slave earphone estimated according to the first relative position and the second relative position.

[0126] It should be noted that the reference earphone distance is determined by the earphone according to the Bluetooth signal sent by the main earphone received by the earphone, and the estimated earphone distance is determined based on the first relative position and the second relative position, see the above method embodiment for details.

[0127] Step S3200: When the corrected estimated earphone spacing is equal to the reference earphone spacing, determine the corrected first relative position and / or the corrected second relative position according to the parameter value of the corrected estimated earphone spacing.

[0128] In this embodiment, the corrected L1 and α1 are the corrected first relative position, and the corrected L2 and α2 are the corrected second relative position.

[0129] Step S3300: taking at least one of the corrected first relative position and the corrected second relative position as the actual position of the electronic device.

[0130] According to an embodiment of the present application, when the first spatial position and the second spatial position do not overlap, the parameter value in the estimated headphone spacing is corrected according to the reference headphone spacing to make the estimated headphone spacing equal to the reference headphone spacing. When the corrected estimated headphone spacing is equal to the reference headphone spacing, the corrected first relative position and / or the corrected second relative position is determined according to the parameter value of the corrected estimated headphone spacing, and at least one of the corrected first relative position and the corrected second relative position is used as the actual position of the electronic device, thereby improving the accuracy of positioning the electronic device based on the headphones.

[0131] In some embodiments, in order to avoid the user's mistaken operation triggering the activation of the positioning function, which would reduce the user experience, the embodiment of the present application provides a mechanism for triggering the activation of the positioning function by combining gesture triggering and voice triggering, that is, the method also includes: step S4100 to step S4300.

[0132] Step S4100: receiving a first trigger operation of the user on the headset.

[0133] In this embodiment, the first trigger operation may be a preset operation for triggering the activation of the positioning function of the electronic device, for example, long pressing the master and slave earphones simultaneously for 10 seconds.

[0134] Those skilled in the art should understand that the first trigger operation may also be other gesture operations, which is not limited here.

[0135] Step S4200, receiving a trigger voice input by a user.

[0136] In this embodiment, the triggering voice may be a preset voice for triggering the activation of the positioning function of the electronic device, for example, a voice of "activate the positioning function".

[0137] Those skilled in the art should understand that the trigger voice may also be other voices, which is not limited here.

[0138] The first trigger operation and the trigger voice can be set independently according to the user's usage habits, or set by the system default of the electronic device, and are not limited here.

[0139] Step S4300: In response to the first trigger operation and the trigger voice, a positioning function activation instruction is sent to the electronic device.

[0140] In this embodiment, after the headset receives the first trigger operation and the trigger voice at the same time, it sends a positioning function activation instruction to the electronic device. The positioning function activation instruction is used to trigger the electronic device to activate the positioning function. That is to say, when the first trigger operation or the trigger voice is received, the headset does not send the positioning function activation instruction to the electronic device. When the electronic device receives the positioning function activation instruction sent by the headset, it transmits a Bluetooth signal.

[0141] In some embodiments, in order to reduce power consumption of the electronic device, when the positioning function of the electronic device is turned on, the electronic device does not transmit a Bluetooth signal. After receiving a positioning instruction sent by the headset, the electronic device transmits a Bluetooth signal.

[0142] Based on this, the method further includes: step S5100 to step S5200.

[0143] Step S5100: When the positioning function of the electronic device is turned on, receiving a second trigger operation of the user on the headset.

[0144] In this embodiment, the second trigger operation may be a preset operation for triggering the headset to send a positioning instruction to the electronic device. For example, the second trigger operation may be an operation of long pressing the main headset 10S.

[0145] Step S5200: In response to the second trigger operation, a positioning instruction is sent to the electronic device.

[0146] In this embodiment, after receiving the second trigger operation, the headset sends a positioning instruction to the electronic device in response to the second trigger operation. The positioning instruction can be used to trigger the electronic device to transmit a Bluetooth signal once, or to trigger the electronic device to continuously transmit a Bluetooth signal, which is not limited here. The headset can locate the electronic device based on the Bluetooth signal transmitted by the electronic device.

[0147] In some embodiments, after determining the actual location of the electronic device, the method further includes:

[0148] Outputting location guidance information according to the actual location of the electronic device.

[0149] In some examples, the actual position of the electronic device may be a first relative position of the electronic device relative to the main earphone. In this case, the position guidance information may be guidance information determined based on the first relative position.

[0150] In other embodiments, the actual position of the electronic device may be a corrected second relative position of the electronic device relative to the headset. In this case, the position guidance information may be guidance information determined based on the corrected second relative position.

[0151] In some other examples, when the positioning function of the electronic device is turned on, once the headset sends a positioning instruction to the electronic device, the electronic device will continue to transmit Bluetooth signals, and the headset will also determine the real-time relative position of the electronic device based on the Bluetooth signal. The headset gives different prompt sounds based on the changes in the real-time relative position of the electronic device, such as when approaching or moving away from the electronic device, so as to guide the user.

[0152] The location guidance information may be a sound prompt.

[0153] Outputting location guidance information according to the actual location of the electronic device can help users quickly find the electronic device.

[0154] According to an embodiment of the present application, when the positioning function is turned on, the electronic device transmits a Bluetooth signal, and then determines the first relative position and the second relative position according to the Bluetooth signal transmitted by the electronic device received by the master and slave earphones, and determines whether the first spatial position corresponding to the first relative position and the second spatial position corresponding to the second relative position overlap, that is, determines whether the positioning of the master earphone and the slave earphone meets the positioning accuracy requirements, and when the first spatial position and the second spatial position overlap, at least one of the first relative position and the second relative position is used as the actual position of the electronic device. This method can be used to perform secondary positioning of the electronic device based on the earphone, and the positioning accuracy is determined by whether the first spatial position and the second spatial position overlap, so that the secondary accurate positioning of the electronic device can be achieved without relying on an external network or satellite signal, and is suitable for the positioning needs of electronic devices in various complex scenarios such as indoors and underground garages. In addition, this positioning method can quickly find the electronic device by positioning the electronic device through the earphone in the scenario where the electronic device such as a mobile phone is lost or stolen.

[0173] Step S12: According to the reference earphone spacing, the parameter value in the estimated earphone spacing is corrected to make the estimated earphone spacing equal to the reference earphone spacing.

[0174] In this example, the parameter value for estimating the earphone distance includes parameter values ​​corresponding to the first relative position and the second relative position.

[0175] Step S13, when the corrected estimated earphone distance is equal to the reference earphone distance, determine the corrected first relative position and / or the corrected second relative position according to the parameter value of the corrected estimated earphone distance.

[0177] Step S15: outputting location guidance information according to the actual location of the electronic device.

[0178] According to an embodiment of the present application, when the positioning function is turned on, the electronic device transmits a Bluetooth signal, and then determines the first relative position and the second relative position according to the Bluetooth signal transmitted by the electronic device received by the master and slave earphones, and determines whether the first spatial position corresponding to the first relative position and the second spatial position corresponding to the second relative position overlap, that is, determines whether the positioning of the master earphone and the slave earphone meets the positioning accuracy requirements, and when the first spatial position and the second spatial position overlap, at least one of the first relative position and the second relative position is used as the actual position of the electronic device. This method can be used to perform secondary positioning of the electronic device based on the earphone, and the positioning accuracy is determined by whether the first spatial position and the second spatial position overlap, so that the secondary accurate positioning of the electronic device can be achieved without relying on an external network or satellite signal, and is suitable for the positioning needs of electronic devices in various complex scenarios such as indoors and underground garages.
