Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or as implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "connected," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; the specific meaning of the above terms in this application will be understood to be a specific case for those of ordinary skill in the art.

The wireless earphone can be used in cooperation with electronic equipment such as a mobile phone, a notebook computer, a watch and the like, and is used for processing audio services such as media, conversation and the like of the electronic equipment and other data services. For example, the audio service may include media services such as playing music, recording, sound in a video file, background music in a game, incoming call alert tone, etc. for the user; the method can also comprise playing voice data of an opposite terminal for a user or collecting voice data of the user and sending the voice data to the opposite terminal under call service scenes such as telephone, weChat voice message, audio call, video call, game, voice assistant and the like.

Wherein, when wireless earphone was taken out by the user from the earphone receiver, need in time detect this wireless earphone and go out the box, just can in time start wireless earphone's correlation function (like bluetooth function and wear detection function etc.). Similarly, when wireless earphone is put into the earphone receiver, the above-mentioned function of wireless earphone just can in time be closed to the income box that needs in time to detect this wireless earphone to save wireless earphone's electric quantity. It follows that the in-out box detection of a wireless headset is particularly important for wireless headsets. In addition, when the earphone goes out of the box or goes into the box, the earphone storage box also needs to be capable of detecting out the in-and-out box of the wireless earphone in time, and the wireless earphone can be charged in time. The wireless earphones provided by the embodiments of the present application are not limited to the headset type, the neck-wearing type, the earplug type, the ear-hanging type, the in-ear type, and the like, and all wireless earphones which need to be used with the earphone storage box belong to the protection scope of the embodiments of the present application. Of course, the following schemes are provided in the drawings and mainly described by taking the earplug type as an example.

Generally, two magnetic sensors (for example, hall sensors) are arranged in an earphone storage box, and the output ends of the magnetic sensors are connected to a processor (for example, an MCU) of the earphone storage box; the inside magnet that has of wireless earphone, the inside magnetic sensor of earphone receiver detects magnetic field variation when wireless earphone inserts or pulls out the earphone receiver, and the magnetic sensor output state changes, and the treater of earphone receiver detects the output state of magnetic sensor and can know whether wireless earphone is in the box. However, all above-mentioned schemes need to set up components and parts on earphone receiver or wireless earphone, occupy the space on earphone receiver or the wireless earphone.

The embodiment of the application provides a wireless headset, a headset storage box and a wireless headset system, wherein the wireless headset can perform information interaction with the headset storage box so as to determine the headset storage box state (in the embodiment of the application, some schemes are also called as the in-box state of the wireless headset), such as a storage state and an uncontained state. So, can avoid because wireless earphone and earphone receiver set up the space that components and parts occupy wireless earphone and earphone receiver, restrict the miniaturization of equipment.

As shown in fig. 4, the earphone storage box 41 includes a second processor 411, and the second processor 411 is connected to the second interface 412; when the wireless earphone 42 is accommodated in the earphone accommodating case 41, the second interface 412 is connected with the first interface 421 of the wireless earphone 42; the first interface 421 is connected to the first processor 422 of the wireless headset 42, wherein fig. 4 shows the wireless headset-L worn on the left side (left) and the wireless headset-R worn on the right side (right), and the following scheme takes either one as an example. The first processor 422 may be the processor 301 (for example, may be an MCU) shown in fig. 3, and the second processor 411 may be a processor in the earphone storage box. The first interface 421 may be the input/output IO interface 306 shown in fig. 3, and the second interface 412 may be an input/output interface in the earphone storage box; for example, the first interface 421 may be a pogo pin, a spring plate, a conductive block, a conductive patch, a conductive sheet, a pin, a plug, a contact pad, a jack, a socket, or the like in an electrical connector; the second port 412 is configured to mate with the first port 421 to enable connection. For example, the first interface may be an input/output IO interface separately provided on the first processor for implementing the present application, and the second interface may be an input/output IO interface separately provided on the second processor for implementing the present application. In some embodiments, the first interface and the second interface may also multiplex interfaces of other existing functions on the device; for example, the first interface may multiplex an interface in an electrical connector (PWR) in the wireless headset that charges the wireless headset; second interface + scheme provided by the embodiment.

Referring to fig. 5, the method for determining the state of the earphone accommodating box specifically includes:

101. the second processor responds to the uncovering operation of the earphone containing box and sends a first message to the first interface through the second interface.

Generally, the cover body and the body of the earphone accommodating box are connected through a hinge (as shown in fig. 1) or are designed in a separated mode (as shown in fig. 2); in order to realize the detection of the opening operation of the earphone accommodating box, a travel switch can be arranged on the body, when the cover body is buckled with the body, the travel switch is triggered to be in a first state, and when the cover body is opened from the body, the travel switch is released and is in a second state; the second processor may determine the decapping operation by detecting the state of the travel switch. Although only one example is described here, in other schemes, the second processor may also detect the state of the cover through a sensor disposed on the body to achieve detection of the cover opening operation, for example, the optical sensor disposed on the inner edge of the body may detect light intensity, and when the cover is engaged with the body, the optical sensor is shielded, and then the optical sensor detects lower light intensity; when the cover body is opened, the optical sensor is exposed, and the optical sensor detects high light intensity; the second processor may determine the uncapping operation by detecting the light intensity of the optical sensor; another example is: the cover body can be provided with a magnet, a magnetic field is detected through a magnetic field sensor arranged on the body, when the cover body is buckled with the body, the magnetic field sensor detects a first magnetic field intensity generated by the magnet on the cover body, the buckling of the cover body and the body is determined, and when the cover body is opened, the magnetic field sensor detects a second magnetic field intensity generated by the magnet on the cover body due to the change of the relative position of the magnet on the cover body and the magnetic field sensor on the body; the second processor may determine the uncapping operation through a change in the magnetic field strength detected by the magnetic field sensor.

102. The second processor determines the in-box state of the wireless headset according to whether the second interface receives a second message which is sent by the first processor through the first interface and responds to the first message.

The wireless earphone comprises a box state and an uncollected state, wherein the box state of the wireless earphone comprises a storage state and an uncollected state, the storage state refers to that the wireless earphone is in the box, and the uncollected state refers to that the wireless earphone is out of the box. In the following schemes, the wireless earphone in-box is used for indicating the storage state, and the wireless earphone out-box is used for indicating the non-storage state. For example: if the second processor receives a second message through the second interface, the second message is a message sent by the first processor through the first interface, and the second processor determines that the earphone storage box is in the storage state. If the second processor determines that the second message is not received through the second interface, the second processor determines that the earphone storage box is in an uncollapsed state.

In the above scheme, specific forms of the first message and the second message are not limited, the second message corresponds to the first message, and as long as the first processor receives, through the first interface, the first message sent by the second processor through the second interface, the first processor feeds back, to the second processor, the second message responding to the first message through the first interface. For example, the first message may be an inquiry message and the second message may be a response message.

In the above scheme, the earphone storage box comprises a second processor and a second interface connected with the second processor; the wireless headset includes a first processor and a first interface connected to the first processor. After the wireless earphone enters the box, the wireless earphone is stored in the earphone storage box, the first interface is connected with the second interface, and when the wireless earphone goes out of the box, the first interface is disconnected with the second interface. In this way, after the second processor detects the uncovering operation of the earphone containing box, the first message is sent to the first interface through the second interface, and the second processor determines the in-box state of the wireless earphone according to whether the second interface receives the second message which is sent by the first processor through the first interface and responds to the first message. For example, when the wireless earphone is taken out of the box and the first interface and the second interface are disconnected, the second processor cannot receive any message through the second interface, and then the earphone storage box is determined to be in the non-storage state; when the wireless earphone is put into the box, the first interface is connected with the second interface, and the second processor can receive a second message which is sent by the first processor through the first interface and responds to the first message through the second interface, so that the earphone containing box is determined to be in the containing state. In the above-mentioned scheme, through having designed the information interaction mode between wireless earphone and the earphone receiver, and confirm the state of earphone receiver according to the result of information interaction mode, compared with the prior art, need not to set up the sensor that is used for the earphone receiver to wireless earphone in the box attitude detection in the earphone receiver, also need not to set up in the earphone and be used for the earphone receiver to wireless earphone specially to wireless earphone's components and parts such as the magnet that box attitude detected, can avoid setting up components and parts on earphone receiver or wireless earphone, occupy the space on earphone receiver or the wireless earphone, be favorable to the miniaturization of equipment.

The following describes a method for determining the state of an earphone accommodating box in the process of box-out detection and box-in detection of a wireless earphone respectively:

for the earphone out-of-box detection process, referring to fig. 6, the method comprises the following steps:

201. the second processor responds to the uncovering operation of the earphone containing box and sends a first message to the first interface through the second interface.

Specifically, when detecting an out-of-box for a wireless headset, the wireless headset should be accommodated in a headset accommodating box. Before the second processor detects the uncovering operation of the earphone containing box, the wireless earphones need to be determined to be in the box (namely, the wireless earphones are contained in the earphone containing box), and the earphone containing box can determine the state of the earphone containing box according to the following mode, for example, the second processor of the earphone containing box can set and record the identification position according to the result of the last wireless earphones going out of the box and going into the box detection process, for example, when the earphone containing box is in the containing state, the recorded identification position is set to be 1, and when the earphone containing box is in the non-containing state, the identification position is set to be 0. In the embodiment of the present application, before the second processor detects the opening operation of the earphone storage case, the state of the earphone storage case may also be determined in the following manner. The second processor sends a first message to the first interface through the second interface according to a preset period; the second processor receives, through the second interface, a second message sent by the first processor through the first interface in response to the first message. In this way, since the second message in response to the first message, which is sent by the first processor of the wireless headset through the first interface, can be periodically received before the second processor detects the uncapping operation, it is stated that the wireless headset is in the box. Therefore, the second processor continues to detect the wireless earphone outgoing box after detecting the opening operation of the earphone accommodating box.

202. The second processor determines that the second message is not received through the second interface, and determines that the earphone storage box is in an uncontracted state.

Specifically, after the wireless headset is taken out of the box, the connection between the first interface and the second interface is disconnected, so that the second processor does not receive a second message which is sent by the first processor through the first interface and responds to the first message through the second interface, and accordingly the second processor can determine that the headset storage box is in an uncontained state, namely, the wireless headset is taken out of the box. In order to ensure the accuracy of the judgment of the wireless earphone out of the box, for example, to avoid the misoperation of a user, the wireless earphone is taken out and put back immediately, and meanwhile, the false detection caused by the communication failure can also be avoided. Step 202 may specifically be that the second processor determines that the second message is not received through the second interface for at least n predetermined periods, and determines that the wireless headset is out of the box, for example, n may be a positive integer, and in some embodiments, n may be set to 3. Referring to fig. 7, the second processor may maintain a count value, and set the count value to 1 if the second processor does not receive the second message after the second processor detects the uncovering operation of the earphone accommodating box and sends the first message for the first time; sending the first message for the second time after a preset period, if the second message is not received, counting the value by +1, and if the counting value is equal to 3, determining that the wireless earphone is taken out of the box; otherwise, if the second processor receives the second message, the count value is cleared. Further, if n is configured to be 3, the count value is cleared after it is determined that the wireless headset is out of the box.

Wherein, in order to save the power consumption of the wireless earphone when the wireless earphone is in the box, the second processor sends the first message, the preset period can be set as long as possible. Then, in order to improve the accuracy of the wireless earphone ejection detection performed by the second processor after the second processor detects the opening operation of the earphone storage box, the duration of a predetermined period may be reduced after the opening operation of the earphone storage box is detected, for example, before the second processor determines the opening operation of the earphone storage box, a first message may be sent to the first processor through the second interface according to a first predetermined period; responding to the uncovering operation of the earphone storage box, and sending a first message to the first processor through the second interface according to a second preset period by the second processor; wherein the time length of the first predetermined period is greater than the time length of the second predetermined period. For example, the predetermined period may be set to 60s before the opening operation of the earphone accommodation case is detected, that is, the second processor transmits the first message to the earphone accommodation case every 60s, and may be reduced to 100ms after the opening operation of the earphone accommodation case is detected, that is, the second processor transmits the first message to the earphone accommodation case every 100 ms.

For the in-box detection process of the earphone, referring to fig. 8, the method comprises the following steps:

301. the second processor responds to the uncovering operation of the earphone containing box and sends a first message to the first interface through the second interface.

When the wireless headset is used for the headset entering detection, the headset containing box is in an uncontained state (namely, an empty box), namely, the wireless headset is not contained in the headset containing box. Before the second processor detects the uncovering operation of the earphone containing box, the earphone containing box needs to be determined to be in an uncontained state (namely, the wireless earphone is not contained in the earphone containing box) at the same time, and the earphone containing box can determine whether the wireless earphone is in the box according to the following mode, for example, the second processor of the earphone containing box can set and record an identification bit according to the result of the last wireless earphone out-box and in-box detection process, for example, when the earphone containing box is in a contained state, the recorded identification bit is set to be 1, and when the earphone containing box is in an uncontained state, the identification bit is set to be 0. In the embodiment of the application, before the second processor detects the uncovering operation of the earphone storage box, it may also be determined that the earphone storage box is in the uncontained state in the following manner. The second processor sends a first message to the first interface through the second interface according to a preset period; the second processor does not receive, via the second interface, a second message sent by the first processor via the first interface in response to the first message. In this way, since the first message can be periodically transmitted to the wireless headset before the second processor detects the lid opening operation, since the wireless headset is not stored in the headset housing case, the second processor cannot receive the second message, which is transmitted from the first processor through the first interface and responds to the first message, through the second interface, thereby indicating that the headset housing case is in the non-stored state. Therefore, the second processor continues to detect the wireless earphone entering box after detecting the opening operation of the earphone accommodating box.

302. The first processor receives a first message sent by the second processor through the second interface through the first interface.

Wherein, prior to step 302, the first processor needs to be able to implement in-box detection of the wireless headset to determine that the wireless headset is in a stowed state (i.e., the wireless headset is in-box). As shown in fig. 4, the wireless headset 42 further includes a magnetic sensor 423 connected to the first processor 422, and the headset housing case 41 includes a magnet 413 corresponding to a position of the magnetic sensor 423; the first processor 422 determines that the wireless headset is in the stowed state, including: the first processor receives a third signal sent by the magnetic sensor, wherein the third signal is generated by the magnetic sensor detecting the magnetic field of the magnet; the first processor determines that the magnetic field of the magnet is greater than a first magnetic field strength threshold according to the third signal, and then determines that the wireless headset is in a storage state.

Fig. 1 shows a schematic view of the earphone housing case 12 for housing the wireless earphone 11. Fig. 2 shows a schematic view of the earphone storage case 22 for storing the wireless earphone 21. In some embodiments, the earphone pods may have one or more magnets therein. For example, the one or more magnets may include: a magnet for attracting the wireless earphone (such as the earphone body of the wireless earphone) to enable the wireless earphone to be accommodated in the accommodating cavity; a magnet used for the closed adsorption of the box body and the box cover of the earphone containing box; and a magnet corresponding to a magnetic sensor in the wireless headset. For example, as shown in fig. 9, two magnets 413 are included in the headphone housing case 41. When the earphone body 42 is accommodated in the accommodating cavity of the earphone accommodating case 41, the magnetic field around the earphone body 42 includes the magnetic field generated by the magnet 413. The magnetic field generated by the magnet 413 affects the magnitude of the magnetic induction collected by the magnetic sensor of the earphone body 42. Illustratively, the magnetic sensor 423 is coupled to the first processor 422 through an IO pin or an interrupt pin of the first processor 422. Alternatively, the magnetic sensor 423 may be coupled to the processor 422 via a data bus. For example, the data bus may be at least one of an SPI bus, an I2C bus, or an I3C bus. The first processor 422 may be a microprocessor. A microprocessor is a central processing unit consisting of one or a few large scale integrated circuits. The magnetic sensor 423 may be a hall sensor, or a magnetometer. When the earphone body 42 is in the case state, the magnetic sensor 423 can detect the magnetic induction intensity of the magnetic field generated by the magnet in the earphone accommodation case 41; when the earphone body is in the out-of-case state, the magnetic sensor 423 cannot detect the magnetic induction intensity of the magnetic field generated by the magnet in the earphone accommodation case 42; alternatively, when the earphone body 42 is in the case state, the magnetic sensor 423 may detect that the magnetic induction intensity of the magnetic field generated by the magnet in the earphone accommodation case 41 is high; when the earphone body is in the outside-case state, the magnetic sensor 423 detects that the magnetic field generated by the magnet in the earphone accommodation case 42 is low. It can be seen that when the earphone body 42 is in different states (e.g., in the case state or the out-of-case state), the magnetic induction intensity detected by the magnetic sensor 423 is different. Accordingly, the first processor may determine that the wireless headset is in the box according to a third signal generated by the magnetic sensor detecting the magnetic field of the magnet. Specifically, the third signal may be an interrupt signal sent by the magnetic sensor, for example, the magnetic sensor generates a high level when detecting that the magnetic field of the magnet is greater than the threshold of the first magnetic field strength, and generates a low level when detecting the second magnetic field strength, so that a signal change process (a change from the high level to the low level forms a falling edge signal) can be detected at the first processor 422, thereby generating the interrupt signal. Alternatively, the magnetic sensor may directly transmit the third signal carrying the strength of the magnetic field of the magnet detected by the magnetic sensor to the first processor, so that the first processor may determine that the wireless headset is in the box when determining that the magnetic field of the magnet is greater than the first threshold magnetic field strength. Certainly, since the speaker in the wireless headset further includes a magnet, and one or more magnets are also present in the headset storage box, the magnetic field detected by the magnetic sensor in the wireless headset is affected, and at this time, the magnetic sensor detects a third signal generated by the sum of the magnetic fields of the plurality of magnets, and thus it is determined that the wireless headset is in the box.

303. The first processor sends a second message to the second processor through the first interface in response to the first message.

304. And the second processor receives the second message through the second interface and determines that the earphone containing box is in the containing state.

Specifically, in the above embodiment, the first processor of the headset mainly detects that the wireless headset is in the box to trigger the receiving process of the first message, that is, only when the headset is in the box and the first interface and the second interface are in the connection state, the headset can receive the first message. As described above, in particular, the earphone may start receiving the first message using the first interface after determining that the wireless earphone is in the box according to the third signal generated by the magnetic sensor detecting the magnetic field of the magnet.

In addition, the first interface and the second interface are input/output (IO) interfaces. The input/output IO interface is mainly used for communication and information exchange among devices; in the embodiment of the present application, the input/output IO interface may implement input or output of a signal from one device to another device, for example: input or output of high and low level signals; the input/output IO interface may also be configured as a communication interface for data transmission, for example, in an embodiment of the present application, the communication interface is mainly used for data transmission of a first message serving as a query message and a second message serving as a response message. When the input/output IO interface is configured as a communication interface, the communication interface may be a universal asynchronous receiver/transmitter (UART) interface. Therefore, the first interface and the second interface need to be configured as communication interfaces before data transmission is performed between the first interface and the second interface. In addition, after the wireless headset is placed in the box, the first interface and the second interface can communicate, so that the wireless headset can keep the communication connection between the first interface and the second interface in the box state; after the wireless headset is taken out of the box, the first interface and the second interface are disconnected, and the first interface and the second interface are no longer communicated, so that the first interface and the second interface recover a non-communication interface (i.e. an input/output (IO) interface), wherein the non-communication interface is not functionally used for transmission of the first message and the second message. When the wireless headset is boxed again, the first interface and the second interface need to be configured as communication interfaces again. Of course, the first interface and the second interface provided in other embodiments of the present application may refer to the above-mentioned related descriptions. Moreover, the descriptions of the communication interface, the non-communication interface, and the input/output IO interface in the embodiments of the present application are mainly used to explain the schemes in the embodiments of the present application, and those skilled in the art may also name these interfaces in other ways, so that when the above functions are implemented, these interfaces may also be named in other ways.

Specifically, as for the earphone in-box detection process, referring to fig. 10, the method includes the following steps:

401. the second processor responds to the uncovering operation of the earphone accommodating box, and the second processor detects signals of the second interface.

402. And when the first processor determines that the wireless headset is in the storage state, the first processor sends a second signal to the second interface through the first interface, and configures the first interface into a communication interface.

403. And when the second processor determines that the signal of the second interface is changed from the first signal to the second signal, the second interface is configured as the communication interface.

The first signal is at a high level and the second signal is at a low level, or the first signal is at a low level and the second signal is at a high level. Illustratively, the second processor is configured to output the first signal to the second interface. The first signal is at a high level and the second signal is at a low level. As shown in fig. 11, the second processor may directly configure the second interface as an internal pull-up, i.e., configure the second interface as a high level VDD through a resistor R. When the first processor determines that the wireless headset is in the box (as described above, the wireless headset detects the interrupt signal of the magnetic sensor), the level of the first interface is pulled down, that is, the low level Vss is configured for the first interface, and at this time, the voltage of the second interface becomes the low level Vss due to the connection of the first interface and the second interface. In this way, the level of the second interface changes from high level to low level, that is, a falling edge interrupt is triggered, and the second processor configures the second interface as a communication interface according to the level change. Furthermore, in order to realize communication with the second interface, after the first interface is configured to be at the low level Vss for a period of time (for example, the specific duration of 500us is determined by the type selection of the first processor and the second processor, and the Vss lasts for a period of time required to ensure that the second processor can respond to the low level in time), the first processor configures the first interface as a communication interface, and then recovers the communication configuration of the first interface. Of course, as mentioned above, the second processor may directly configure the second interface as an internal pull-down, i.e. the second interface is configured to the low level Vss via the resistor R. When the first processor determines that the wireless headset is in the box (as described above, the wireless headset detects the interrupt signal of the magnetic sensor), the level of the first interface is raised, that is, the high level VDD is configured for the first interface, and at this time, the voltage of the second interface changes to the high level VDD due to the connection between the first interface and the second interface. In this way, the level of the second interface changes from low level to high level, that is, a rising edge interrupt is triggered, and the second processor configures the second interface as a communication interface according to the level change. In another example, as shown in fig. 12, the second interface is connected to a first level terminal V1 through a resistor R, wherein the first level terminal V1 is used for providing the first signal to the second port. In this example, the first signal can be provided to the second interface via an external voltage terminal V1 and a resistor R.

404. The second processor sends the first message to the first interface through the second interface.

405. The first processor receives a first message sent by the second processor through the second interface through the first interface.

406. The first processor sends a second message to the second interface through the first interface in response to the first message, the second message corresponding to the first message.

407. And the second processor receives the second message through the second interface and determines that the earphone containing box is in the containing state.

Specifically, in the above embodiment, the process of configuring the communication interface is mainly triggered by the detection of the in-box of the headset by the first processor of the headset, and as described above, specifically, the headset may configure the first interface as the communication interface after determining that the wireless headset is in the box according to the third signal generated by the magnetic sensor detecting the magnetic field of the magnet. Further, after the earphone is determined to be taken out of the box, the first interface may be reconfigured as the input/output IO interface due to the fact that the communication between the earphone and the earphone receiving box is ended, and specifically, the first processor may determine that the wireless earphone is taken out of the box according to the magnetic field of the magnetic sensor detected by the magnetic sensor, and configure the first interface as the input/output IO interface after determining that the wireless earphone is taken out of the box. In addition, after the earphone storage box determines that the earphone is taken out of the box, the second interface can be configured as an input/output (IO) interface. For example, as shown in connection with fig. 6, the second processor may configure the second interface as an IO interface after step 202. For another example, as shown in connection with fig. 7, the second processor may configure the second interface as an input/output IO interface after determining that the wireless headset is out of the box and clearing the count value.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
