[0028] Please refer to Figure 1 , which is a block diagram of an embodiment of the earphone system according to the present application. As Figure 1 shown, in this embodiment, the earphone system 100 includes: a charging case 110 and an earphone 120, and the earphone 120 is detachably assembled in the charging case 110; the charging case 110 includes: a processing module 112, a power output module 114, a first switch module 116 and an output interface 118, the power output module 114 is electrically connected to the processing module 112, and the first switch module 116 is electrically connected to the processing module 112 and the power output module 114; the earphone 120 includes: a core module 122, a second switch module 124 and a connection interface 126, the second switch module 124 is electrically connected to the core module 122, and the connection interface 126 is electrically connected to the second switch module 124 and is detachably electrically connected to the output interface 118. Among them, the processing module 112, the power output module 114, the first switch module 116, the core module 122 and the second switch module 124 can be implemented in various ways, including software, hardware, firmware or any combination thereof; the output interface 118 includes contacts 50a, 50b (contact 50a is electrically connected to the first switch module 116, and contact 50b is grounded), and the connection interface 126 includes contacts 60a, 60b (contact 60a is electrically connected to the second switch module 124, and contact 60b is grounded).

[0029] In implementation, the technologies proposed can use software or firmware that can be stored on a machine-readable storage medium, such as read-only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory, etc., and can be executed by one or more general-purpose or special-purpose programmable microprocessors. Signals and / or power can be transmitted between the power output module 114 and the processing module 112, between the first switch module 116 and the processing module 112, between the first switch module 116 and the power output module 114, between the second switch module 124 and the core module 122, and between the connection interface 126 and the second switch module 124 in a wireless or wired manner.

[0030] In one embodiment, the earphone 120 can be, but is not limited to, a true wireless stereo (TWS) earphone.

[0031] In this embodiment, a first identification time period T1 is set in the processing module 112. The first identification time period T1 can be, but is not limited to, between 100 milliseconds (ms) and 300 ms. However, this embodiment is not intended to limit the present application, and the actual range of the first identification time period T1 can be adjusted according to actual needs. In addition, the processing module 112 can also be used to control the power output module 114 to make the power output module 114 output power to the first switch module 116.

[0032] In this embodiment, the earphone system 100 includes a test mode and a communication mode. Please refer to Figure 2 , Figure 2 For Figure 1 is a block diagram of an embodiment of the earphone system in the test mode. As Figure 2 shown, during the first identification time period T1 when the earphone 120 is electrically connected to the charging case 110, in the test mode of the earphone system 100, the first switch module 116 switches to allow the charging case 110 to transmit power to the earphone 120 through the power output module 114 and the first switch module 116.

[0033] Furthermore, in the test mode of the earphone system 100, the processing module 112 controls the first switch module 116 to make the output interface 118 output the power transmitted by the power output module through the first switch module 116, and the core module 122 controls the second switch module 124 to make the connection interface 126 receive the power from the output interface 118 and transmit the power to the core module 122 through the second switch module 124.

[0034] More specifically, the charging case 110 may include a timer (not shown) or a unit or circuit with a timing function may be provided in the processing module 112. Therefore, when the earphone 120 is placed in the charging case 110 (i.e., the earphone 120 is electrically connected to the charging case 110), the charging case 110 will detect a change in the level on the contact 50a, for example, a drop in the level to within a preset range. At this time, the timing mechanism is started; the earphone system 100 is in the test mode; the processing module 112 outputs a detection signal to the power output module 114 to cause the power output module 114 to output power; the processing module 112 outputs a control signal to the first switch module 116 to cause the first switch module 116 to switch, so that the power output by the power output module 114 is transmitted to the earphone 120 through the first switch module 116 and the contact 50a; and the charging case 110 determines based on the timer that when it is within the first identification time period T1 during which the earphone 120 is electrically connected to the charging case 110, the charging case 110 continuously transmits the power to the earphone 120 through the power output module 114 and the first switch module 116; and the earphone 120 may include another timer (not shown) or a unit or circuit with a timing function may be provided in the core module 122. When the earphone 120 is placed in the charging case 110 (i.e., the earphone 120 is electrically connected to the charging case 110), the earphone 120 will detect a change in the level on the contact 60a, for example, a rise in the level to within another preset range. At this time, the other timing mechanism is started; the core module 122 outputs a control signal to the second switch module 124 to cause the second switch module 124 to switch, so that the power output by the charging case 110 is transmitted to the core module 122 through the contact 60a and the second switch module 124; and the earphone 120 determines based on the other timer that when it is within the first identification time period T1 during which the earphone 120 is electrically connected to the charging case 110, the earphone 120 continuously receives the power through the contact 60a and the second switch module 124.

[0035] In one embodiment, the earphone 120 may further include a battery module 127. The battery module 127 is electrically connected to the core module 122, and the battery module 127 stores the power received by the core module 122.

[0036] Please refer to Figure 3 , Figure 3 For Figure 1 an embodiment block diagram of the earphone system in the communication mode. As Figure 3 shown, after the earphone 120 is electrically connected to the charging case 110 for more than the first identification time period T1, the earphone system 100 is in the communication mode, and the first switch module 116 switches to allow the charging case 110 to transmit a data signal to the earphone 120 through the processing module 112 and the first switch module 116.

[0037] Furthermore, in the communication mode of the headset system 100, the processing module 112 controls the first switch module 116 so that the output interface 118 outputs the data signal transmitted by the processing module 112 through the first switch module 116, and the core module 122 controls the second switch module 124 so that the connection interface 126 receives the data signal from the output interface 118 and transmits the data signal to the core module 122 through the second switch module 124.

[0038] More specifically, the charging case 110 may include a timer (not shown). The charging case 110 can determine based on the timer that after the headset 120 is placed in the charging case 110 for more than the first identification time period T1, the headset system 100 switches from the test mode to the communication mode. The processing module 112 outputs a data signal to the first switch module 116. At this time, the processing module 112 outputs another control signal to the first switch module 116 to cause the first switch module 116 to switch, so that the data signal output by the processing module 112 is transmitted to the headset 120 through the first switch module 116 and the contact 50a; and the headset 120 may include another timer (not shown). The headset 120 can determine based on the other timer that after the headset 120 is placed in the charging case 110 for more than the first identification time period T1, the core module 122 outputs a control signal to the second switch module 124 to cause the second switch module 124 to switch, so that the data signal output by the charging case 110 is transmitted to the core module 122 through the contact 60a and the second switch module 124. Wherein, the data signal may be, but is not limited to, the current remaining storage power of the charging case 110.

[0039] Please refer to Figure 4 , which is another block diagram of the headset system according to the present application. As Figure 4 shown, in addition to including the core module 122, the second switch module 124, and the connection interface 126, the headset 120 may further include a communication module 128. The communication module 128 is electrically connected to the core module 122, and the communication module 128 transmits the data signal received by the core module 122 to the external device 70. For example, when the data signal is the current remaining storage power of the charging case 110 and the headset 120 can be connected to a smart phone or a computing device (i.e., the external device 70) through the communication module 128, the headset 120 can transmit the data signal to the smart phone or the computing device for display, so that the user knows the current remaining storage power of the charging case 110.

[0040] In this embodiment, the core module 122 may include a control circuit 80 and a charging circuit 90. The control circuit 80 controls the second switch module 124 and receives the data signal; the charging circuit 90 is electrically connected to the battery module 127 and receives the power so that the battery module 127 stores the power.

[0041] In this embodiment, the charging case 110 includes: a processing module 112, a power output module 114, a first switch module 116, and an output interface 118. The first switch module 116 may include a first switch unit 31 and a second switch unit 32. The first switch unit 31 is electrically connected to the processing module 112 and the output interface 118. The second switch unit 32 is electrically connected to the processing module 112, the power output module 114, and the output interface 118. The processing module 112 controls the turning on (switch on) and turning off (switch off) of the first switch unit 31 and the second switch unit 32. The second switch module 124 may include a third switch unit 33 and a fourth switch unit 34. The third switch unit 33 and the fourth switch unit 34 are respectively electrically connected to the core module 122 and the connection interface 126. The core module 122 controls the turning on and turning off of the third switch unit 33 and the fourth switch unit 34. Among them, the first switch unit 31, the second switch unit 32, the third switch unit 33, and the fourth switch unit 34 may be, but are not limited to, transistors.

[0042] In the test mode of the headphone system 100, the processing module 112 turns off the first switch unit 31 and turns on the second switch unit 32, so that the output interface 118 outputs the power transmitted by the power output module through the second switch unit 32; and the core module 122 turns off the third switch unit 33 and turns on the fourth switch unit 34, so that the connection interface 126 receives the power from the output interface 118 and transmits the power to the core module 122 through the fourth switch unit 34.

[0043] In the communication mode of the headphone system 100, the processing module 112 turns on the first switch unit 31 and turns off the second switch unit 32, so that the output interface 118 outputs the data signal transmitted by the processing module 112 through the first switch unit 31; and the core module 122 turns on the third switch unit 33 and turns off the fourth switch unit 34, so that the connection interface 126 receives the data signal from the output interface 118 and transmits the data signal to the core module 122 through the third switch unit 33.

[0044] Please refer to Figure 5 , which is another block diagram of the headphone system according to the present application. As Figure 5As shown, the headset system 100 may include N headsets 120, and the charging case 110 may further include: N first switch modules 116 and N output interfaces 118; the N first switch modules 116 are electrically connected to the processing module 112 and the power output module 114 respectively, and are electrically connected to the N output interfaces 118 in a one-to-one manner. N is an integer greater than or equal to 2. In this embodiment, the number of headsets 120 is two (i.e., N = 2), but this embodiment is not intended to limit the present application. When the headset system 100 includes multiple headsets 120, the charging and communication methods between the charging case 110 and any headset 120 are the same as those in the above embodiment, and the detailed description has been given in the above paragraph and will not be repeated here.

[0045] Please refer to Figures 6 to 9 , Figure 6 is Figure 5 a schematic diagram of an embodiment in which the headset is separated from the charging case, Figure 7 is Figure 6 a top view of an embodiment after the headset is placed in the charging case, Figure 8 is Figure 7 a sectional view of an embodiment of line AA of Figure 9 is Figure 8 an enlarged schematic diagram of block B of Figures 6 to 9 As shown, the charging case 110 may further include a magnetic unit 119, and the headset 120 further includes a Hall sensing unit 129. The Hall sensing unit 129 is electrically connected to the core module 122. When the Hall sensing unit 129 senses the magnetic field of the magnetic unit 119, the output interface 118 is electrically connected to the connection interface 126.

[0046] More specifically, the magnetic unit 119 is disposed around the accommodation groove 113 of the charging case 110 for adapting to the headset 120 and is located inside the housing 111 of the charging case 110. The Hall sensing unit 129 is disposed inside the housing 121 of the headset 120 and the setting position corresponds to the position of the accommodation groove 113, so that when the headset 120 is placed in the charging case 110, the setting positions of the Hall sensing unit 129 and the magnetic unit 119 correspond to each other, enabling the headset 120 to determine its electrical connection with the charging case 110 not only by detecting a change in the level on the contact 60a, but also by the Hall sensing unit 129 sensing the magnetic field of the magnetic unit 119.

[0047] Please refer to Figure 2, in addition to the test mode and the communication mode, the headset system 100 may further include a charging mode, and the processing module 112 may further be provided with a second identification time period T2 therein. After the second identification time period T2 after the output interface 118 of the charging case 110 outputs the data signal, the headset system 100 switches to the charging mode, and the first switch module 116 makes a switch so that the output interface 118 continuously outputs the power to the connection interface 126. Wherein, the second identification time period T2 may be, but is not limited to, between 100 ms and 1000 ms. However, this embodiment is not intended to limit the present application, and the actual range of the second identification time period T2 can be adjusted according to actual requirements.

[0048] Furthermore, in the charging mode of the headset system 100, the processing module 112 controls the first switch module 116 so that the output interface 118 outputs the power transmitted by the power output module 114 through the first switch module 116, and the core module 122 controls the second switch module 124 so that the connection interface 126 receives the power from the output interface 118 and transmits the power to the core module 122 through the second switch module 124.

[0049] More specifically, the charging case 110 may include a timer (not shown) or a unit or circuit with a timing function may be provided in the processing module 112. The charging case 110 may determine, based on the timer, that after the second identification time period T2 (i.e., determining that the headset 120 has been placed in the charging case 110 for more than the time period T1 + T2) after the output interface 118 outputs the data signal, the headset system is switched from the communication mode to the charging mode. The processing module 112 outputs a charging signal to the power output module 114 to make the power output module 114 output power; the processing module 112 outputs a control signal to the first switch module 116 to make the first switch module 116 make a switch, so that the power output by the power output module 114 is transmitted to the headset 120 through the first switch module 116 and the contact 50a; and the core module 122 outputs a control signal to the second switch module 124 to make the second switch module 124 make a switch, so that the power output by the charging case 110 is transmitted to the core module 122 through the contact 60a and the second switch module 124, and the battery module 127 stores the power received by the core module 122.

[0050] Please refer to Figure 10, which is a flowchart of the method of the first embodiment of the communication method between the charging case and the earphone according to the present application. In this embodiment, the communication method between the charging case and the earphone includes the following steps: The earphone is placed in the charging case, and the earphone is electrically connected to the charging case (step 410); during the first identification time period when the earphone is electrically connected to the charging case, including the earphone system of the earphone and the charging case in the test mode, the first switch module inside the charging case is switched, so that the charging case transmits power to the earphone (step 420); the earphone system is in the test mode, the second switch module inside the earphone is switched, so that the earphone receives power (step 430); after the earphone is electrically connected to the charging case for more than the first identification time period, the earphone system switches to the communication mode, the first switch module inside the charging case is switched, so that the charging case transmits a data signal to the earphone (step 440); and the earphone system is in the communication mode, the second switch module inside the earphone is switched, so that the earphone receives the data signal and transmits the data signal to an external device (step 450).

[0051] Through the above steps, after the earphone is electrically connected to the charging case for more than the first identification time period, when the earphone system is in the communication mode, the first switch module is switched, so that the charging case transmits a data signal to the earphone. Therefore, it can be made that the charging case can realize the communication between the earphone and the charging case based on the existing contacts for charging only by switching the first switch module. In addition, the data signal can be transmitted to an external device through the earphone for presentation, so that the user can know the relevant information of the charging case 110 (for example: the data signal may include the current remaining storage power of the charging case 110). The detailed description has been explained in the above paragraph and will not be repeated here.

[0052] In one embodiment, please refer to Figure 11 , which is a flowchart of the method of the second embodiment of the communication method between the charging case and the earphone according to the present application. As Figure 11 shown, in addition to including the above steps 410 to 450, the communication method between the charging case and the earphone may further include the following steps: after the second identification time period after the charging case outputs the data signal, the earphone system switches to the charging mode, the first switch module inside the charging case is switched, so that the charging case continuously outputs power to the earphone (step 460). The detailed description has been explained in the above paragraph and will not be repeated here.

[0053] In one embodiment, the first switch module includes a first switch unit and a second switch unit. The first switch unit controls the transmission of the data signal, and the second switch unit controls the transmission of the power; when the earphone system is in the test mode, the charging case closes the first switch unit and opens the second switch unit; when the earphone system is in the communication mode, the processing module opens the first switch unit and closes the second switch unit. The detailed description has been explained in the above paragraph and will not be repeated here.

[0054] In one embodiment, the second switch module includes a third switch unit and a fourth switch unit. The third switch unit controls the transmission of the data signal, and the fourth switch unit controls the transmission of the power. In the test mode of the headphone system, the core module turns off the third switch unit and turns on the fourth switch unit. In the communication mode of the headphone system, the core module turns on the third switch unit and turns off the fourth switch unit. The detailed description has been given in the above paragraphs and will not be repeated here.

[0055] In one embodiment, please refer to Figure 12 , which is a flowchart of a method according to a third embodiment of a communication method between a charging case and a headphone according to the present application. As Figure 12 shown, the communication method between the charging case and the headphone includes the following steps: The headphone is placed in the charging case, and the headphone is electrically connected to the charging case (step 510); between the first identification time periods when the Hall sensing unit of the headphone senses the magnetic unit in the charging case, the headphone system including the headphone and the charging case is in the test mode, and the first switch module inside the charging case is switched to allow the charging case to transmit power to the headphone (step 520); the headphone system is in the test mode, and the second switch module inside the headphone is switched to allow the headphone to receive power (step 530); after the Hall sensing unit of the headphone senses that the magnetic unit in the charging case exceeds the first identification time period, the headphone system switches to the communication mode, and the first switch module inside the charging case is switched to allow the charging case to transmit a data signal to the headphone (step 540); and the headphone system is in the communication mode, and the second switch module inside the headphone is switched to allow the headphone to receive the data signal and transmit the data signal to an external device (step 550).

[0056] Through the above steps, the headphone can sense the magnetic field of the magnetic unit through the Hall sensing unit to determine its electrical connection with the charging case.
