[0021] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation on the present invention.

[0022] TWS (True Wireless Earbuds) earphones are stereo Bluetooth earphones with two separate ears. Both earphones can have a Bluetooth SoC (System on Chip) and an antenna. Due to the removal of the wire design, TWS earphones are relatively small and light. The TWS earphone charging case is a common device existing specifically for storing and charging TWS earphones. It is designed independently of the smart phone. The specific structure is as Figure 1 shown. A battery compartment 111 is provided in the TWS earphone charging case 110. The battery compartment can accommodate the left and right TWS earphones 120 to achieve the functions of storage and charging. However, this will cause the user to need to carry the charging case at all times when using, which adds a certain burden to the user.

[0023] At the same time, the Bluetooth Core Specification version 5.1 has introduced the function of high-precision positioning through AoA / AoD. However, due to the limitations of the internal structure of the smart phone, it is relatively difficult to simply add an antenna on the smart phone side, and the number of antennas is directly related to the positioning accuracy of the Bluetooth AoA / AoD solution.

[0024] Based on this, the present application provides a mobile terminal. The mobile terminal can not only realize the functions of storing and charging wireless earphones, but also use the antenna of the wireless earphone as an additional antenna of the mobile terminal to form a multi-antenna array with the built-in antenna of the mobile terminal, so that the mobile terminal can realize AoA / AoD high-precision positioning. Among them, the mobile terminal can include mobile phones, laptops, tablet computers, in-vehicle computers, wearable mobile devices, POS machines, etc. Specifically, the present application does not make any restrictions.

[0025] Figure 2 For a structural schematic diagram of a mobile terminal according to an embodiment of the present invention, refer to Figure 2 shown. The mobile terminal includes: a main body 210 and a first processor 211 disposed in the main body 210. The main body 210 defines a placement compartment 212 for placing the wireless earphone 220. The wireless earphone 220 includes an antenna 221 and a wireless communication module 222. The wireless communication module 222 is connected to the antenna 221 to perform signal transmission and reception through the antenna 221. The first processor 211 communicates with the wireless communication module 222 when the wireless earphone 220 is placed in the placement compartment 212.

[0026] Specifically, a placement bin 212 is defined inside the body 210 of the mobile terminal for placing the wireless earphone 220. The placement bin 212 is usually a three-dimensional space with a one-way opening, and a clamping structure, a damping structure, a suction structure, etc. for positioning the wireless earphone 220 can be provided therein. For example, taking the surface where the display screen of the mobile terminal is located as the upper surface as a reference, a receiving groove can be opened on any side surface or the lower surface of the mobile terminal to serve as the placement bin 212. The receiving groove can be one or two. When it is one, one or two wireless earphones 220 can be accommodated. When it is two, as Figure 3 shown, each receiving groove can accommodate one wireless earphone 220. That is to say, the wireless earphone 220 in this application can be one or more, and multiple wireless earphones 220 can be independent of each other. Optionally, a protective cover can also be provided on the receiving groove to protect the wireless earphone 220. The wireless earphone 220 can be a Bluetooth earphone. When the wireless earphone 220 is a Bluetooth earphone, the wireless communication module 222 can be a Bluetooth communication module. More specifically, the wireless communication module 222 can be a Bluetooth Controller, which is connected to the antenna 221 to perform signal transmission and reception through the antenna 221, where the antenna 221 can be a radio frequency antenna.

[0027] A first processor 211 is also provided in the body 210 of the mobile terminal. When the wireless earphone 220 is placed in the placement bin 212, the first processor 211 communicates with the wireless communication module 222 in the wireless earphone 220. At this time, the antenna 221 in the wireless earphone 220 can be used as an additional antenna of the mobile terminal, forming a multi-antenna array with the original antenna (not shown in the figure) of the mobile terminal, so that the mobile terminal can achieve high-precision AoA / AoD positioning. Among them, the first processor 211 can be an application processor.

[0028] In one embodiment, when the wireless earphone 220 is placed in the placement bin 212, the first processor 211 uses the wireless communication module 222 and the antenna 221 and realizes positioning based on the AoA / AoD technology.

[0029] Specifically, AoA high-precision positioning is angle-of-arrival positioning. This positioning method requires the receiver to have at least two antennas, and the transmitter can have only one antenna. The receiver can calculate the angle of the signal source through at least two signals received by at least two antennas, so as to achieve high-precision positioning. In this application, when the wireless earphone 220 is placed in the placement bin 212, since the antenna 221 in the wireless earphone 220 can be used as an additional antenna of the mobile terminal, forming a multi-antenna array with at least two antennas with the original antenna of the mobile terminal, the first processor 211 can calculate the angle of the signal source through multiple signals received by the multi-antenna array, so as to achieve AoA high-precision positioning.

[0030] AoD high-precision positioning, i.e., Angle of Departure positioning, requires the transmitter to have at least two antennas, while the receiver can have only one antenna. The receiver can receive at least two signals transmitted by the transmitter through at least two antennas to calculate the angle of the signal source, thereby achieving high-precision positioning. In this application, when the wireless headset 220 is placed in the placement bin 212, since the antenna 221 in the wireless headset 220 can be used as an additional antenna of the mobile terminal, forming a multi-antenna array with at least two antennas together with the original antennas of the mobile terminal, the first processor 211 can send multiple signals to the receiver through the multi-antenna array, so that the receiver can calculate the angle of the signal source according to the multiple signals, thereby achieving AoD high-precision positioning.

[0031] Thus, in this application, when the wireless headset is placed in the mobile terminal, by using the antenna of the wireless headset as an additional antenna of the mobile terminal and forming a multi-antenna array with the built-in antenna of the mobile terminal, the mobile terminal can achieve AoA / AoD high-precision positioning. At the same time, the wireless headset is accommodated in the mobile terminal, enabling the storage of the wireless headset.

[0032] In one embodiment, an interface module (not shown in the figure) is provided in the placement bin 212. Among them, the first processor 211 communicates with the wireless communication module 222 through the interface module when the wireless headset 220 is placed in the placement bin 212.

[0033] Specifically, when taking the surface where the display screen of the mobile terminal is located as the upper surface as a reference and opening a receiving groove on any side or the lower surface of the mobile terminal to serve as the placement bin 212, the interface module can be provided at the bottom or side wall of the receiving groove. At the same time, an interface module matching the interface module in the receiving groove can be provided at the corresponding position of the wireless headset 220, so that when the wireless headset 220 is placed in the placement bin 212, the connection between the first processor 211 and the wireless communication module 222 can be realized through the two interface modules. In practical applications, the interface module in the receiving groove can have protruding metal contacts, and at the same time, the interface module on the wireless headset 220 can have metal contact pieces. When the wireless headset 220 is placed in the placement bin 212, the metal contacts come into contact with the metal contact pieces, and the communication between the first processor 211 and the wireless communication module 222 is realized through the metal contacts and the metal contact pieces.

[0034] In one embodiment, the first processor 211 conducts data communication at the HCI level with the wireless communication module 222 through the interface module when the wireless headset 220 is placed in the placement bin 212.

[0035] Specifically, when the wireless earphone 220 is a Bluetooth earphone, the wireless communication module 222 can be a Bluetooth communication module. When the wireless earphone 220 is placed in the charging case 212, the first processor 211 can perform data communication with the wireless communication module 222 at the HCI level through the interface module. Among them, HCI is a layer of protocol located between the logical link control and adaptation protocol layer and the link management protocol layer of the Bluetooth system. HCI provides a unified interface for upper-layer protocols to enter the link management and a unified way to enter the baseband.

[0036] In one embodiment, referring to Figure 4 As shown, the wireless earphone 220 further includes a second processor 223. Among them, when the wireless earphone 220 is placed in the charging case 212, the first processor 211 also communicates with the second processor 223 to transmit audio data to the second processor 223. The second processor 223 is also used to control the wireless earphone 220 to play audio data when the wireless earphone 220 is taken out of the charging case 212.

[0037] Furthermore, the first processor 211 communicates with the second processor 223 through the interface module when the wireless earphone is placed in the charging case 212. This interface module can be any general interface module. That is to say, the first processor 211 and the wireless communication module 222 can communicate through the HCI interface, and the first processor 211 and the second processor 223 can communicate through any general interface, which is not limited here.

[0038] Specifically, the wireless earphone 220 further includes a second processor 223. When the wireless earphone 220 is put into the charging case 212, the first processor 211 also communicates with the second processor 223 through the interface module to transmit the audio data in the mobile terminal to the second processor 223. Then, when the wireless earphone 220 leaves the charging case 212, the second processor 223 can control the wireless earphone 220 to play audio data. Thus, when the wireless earphone 220 leaves the charging case, even if the wireless earphone 220 has not established a communication connection with the mobile terminal, the wireless earphone 220 can ensure that the user can hear the audio for a period of time by playing the pre-stored audio data. It can be understood that through the pre-storing method, when the wireless earphone 220 leaves the charging case and establishes a communication connection with the mobile terminal for audio playback, the currently playing audio data can also be pre-stored, so that even if there is a short communication interruption, such as the user temporarily leaves the mobile terminal, the audio playback can be ensured not to be interrupted.

[0039] In one embodiment, referring to Figure 4 As shown, the wireless earphone 220 further includes a memory 224. The memory 224 is connected to the second processor 223 to store audio data.

[0040] That is to say, the second processor 223 can be connected to the memory 224. After the second processor 223 receives the audio data transmitted by the first processor 211 through the interface module, it can store the audio data in the memory 224, so that when the wireless earphone 220 leaves the charging case 212, the second processor 223 can read the audio data from the memory 224 and play it. It can be understood that since a certain amount of audio data needs to be stored in the memory 224, the capacity of the memory 224 is relatively increased compared to the current capacity of wireless earphones, and it can be specifically set according to the actual situation.

[0041] In one embodiment, the second processor 223 is further configured to perform pairing by interacting with the first processor 211 when the wireless earphone 220 is placed in the charging case 212, and communicate with the mobile terminal through the wireless communication module 222 and the antenna 221 when the wireless earphone 220 is taken out of the charging case 212.

[0042] Specifically, in the traditional way, when audio playback or voice calls are required through TWS earphones, the TWS earphones need to be paired with a smartphone via Bluetooth and establish a connection to establish a wireless communication connection between the TWS earphones and the smartphone. The main purpose is to exchange Bluetooth pairing information, and in this application, this pairing process can be omitted.

[0043] Specifically, when the wireless earphone 200 is placed in the charging case 212, the second processor 223 in the wireless earphone 220 can communicate with the first processor 211 in the mobile terminal. At this time, the first processor 211 can interact with the second processor 223 to exchange pairing information related to the wireless communication connection between the mobile terminal and the wireless earphone 220. For example, the first processor 211 can interact with the second processor 223 to exchange keys and other security-related information to authenticate the identities of the wireless earphone 220 and the mobile terminal, and then establish a wireless communication connection between the two. When the wireless earphone 220 is a Bluetooth earphone, a Bluetooth communication connection will be established between the two. In this way, when the wireless earphone 220 leaves the charging case 212, the information interaction of keys and other security-related information has been performed, so there is no need to pair again. As long as wireless communication is performed with the mobile terminal through the wireless communication module 222 and the antenna 221, the pairing process between the wireless earphone and the mobile terminal can be omitted, and the security of information can be ensured at the same time.

[0044] In one embodiment, the wireless earphone 220 further includes a first power module (not shown in the figure), and the mobile terminal further includes a second power module (not shown in the figure). The first processor 211 controls the second power module to charge the first power module through the interface module when the wireless earphone 220 is placed in the charging case 212.

[0045] That is to say, when the wireless earphone 220 is placed in the charging case 212, not only can data transmission between the wireless earphone 220 and the mobile terminal be performed through this interface module, but also the charging function of the mobile terminal for the wireless earphone 220 can be realized. Thus, when the wireless earphone is accommodated in the mobile terminal, data transmission and charging of the wireless earphone can be realized through one interface module. Of course, data transmission and charging can also be realized through two interface modules respectively, and specific details are not limited here.

[0046] Optionally, the interface module may include at least one of a UART (Universal Asynchronous Receiver / Transmitter) interface module and a USB interface module. Of course, it may also include other interface modules, such as an RS232 interface module, etc., and specific details are not limited here.

[0047] To enable those skilled in the art to understand the present application more clearly, the present application will be further described below in conjunction with specific application scenarios.

[0048] Specifically, when the wireless earphone 220 is placed in the charging case 212 of the mobile terminal, the first processor 211 in the mobile terminal communicates with the wireless communication module 222 and the second processor 223 in the wireless earphone 220 through the interface module. At this time, the first processor 211 can control the second power module in the mobile terminal to charge the first power module in the wireless earphone 220 through the interface module. At the same time, the first processor 211 communicates with the second processor 223 through the interface module to perform the interaction of keys and other security-related information, thereby establishing a wireless communication connection between the mobile terminal and the wireless earphone 200.

[0049] When the mobile terminal needs to achieve high-precision positioning, the first processor 211 communicates with the wireless communication module 222 through the interface module, and through the wireless communication module 222 and the antenna 221, high-precision positioning is achieved based on the AoA / AoD technology.

[0050] When the wireless earphone 220 needs to play audio, one scenario is real-time audio playback. When the user takes the wireless earphone 220 out of the charging case 212, real-time audio playback can be performed; another scenario is local audio playback. Since the first processor 211 can send audio data to the second processor 223 when the wireless earphone 220 is put into the case, the first processor 211 can pre-store a certain amount of audio data (such as audio data downloaded by the user) in the memory 224 of the wireless earphone 220. In this way, even if the wireless earphone 220 is not wirelessly connected to the mobile terminal, the wireless earphone can play the pre-stored audio data. For example, before the user runs, a certain amount of audio data can be pre-stored in the wireless earphone 220 through the mobile terminal, and then only the wireless earphone 220 needs to be carried during running. In this way, the user can listen to music without carrying the mobile terminal, thus improving the user experience.

[0051] In summary, for the mobile terminal according to the embodiment of the present invention, the charging case is defined by the body to be suitable for placing the wireless earphone. The wireless earphone includes an antenna and a wireless communication module, and the wireless communication module is connected to the antenna for signal transmission and reception through the antenna. At the same time, the first processor in the body communicates with the wireless communication module when the wireless earphone is placed in the charging case. Thus, the antenna of the wireless earphone can be used as an additional antenna of the mobile terminal to form a multi-antenna array with the built-in antenna of the mobile terminal, enabling the mobile terminal to achieve high-precision AoA / AoD positioning.
