Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely 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. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
True Wireless headsets (True Wireless Stereo) are widely popular in the market due to their lack of wire constraints. The inventor of the application discovers through long-term research that the charging box of the current true wireless earphone only charges for the earphone, and can not control the earphone to perform other corresponding operations, so that the interaction between the charging box with single function and the earphone is less, and the diversified control of the earphone can not be realized. In order to solve the above technical problem, at least the following embodiments are provided.
Referring to fig. 1, a wireless headset assembly 100 described in the embodiments of the wireless headset assembly of the present application includes: an earphone box assembly 10, a first earphone 20 and a second earphone 30.
Wherein the earphone box assembly 10 is adapted to receive a first earphone 20 and a second earphone 30. As shown in fig. 1, for example, the earphone box assembly 10 includes a housing 101 and a box cover 102, wherein the housing 101 forms two accommodating cavities 1010, and the two accommodating cavities 1010 may or may not be connected. Of course, in some embodiments, the housing 101 may have only one receiving cavity 1010, and the first earphone 20 and the second earphone 30 are jointly received in the receiving cavity 1010. The box cover 102 can cover the housing 101 to cover the two accommodating cavities 1010, so that the earphone can be protected on one hand, and the dustproof function can be achieved on the other hand.
Referring to fig. 1 and 2, the earphone box assembly 10 includes a control circuit 103 and a trigger circuit 104. The control circuit 103 and the trigger circuit 104 may be disposed within the housing 101. The control circuit 103 is coupled to the trigger circuit 104. The control circuit 103 is used to control the operation of the entire earphone box assembly 10, and is, for example, a micro processor unit (MCU). The trigger circuit 104 is controlled by the control circuit 103, and the control circuit 103 is used for controlling the trigger circuit 104 to form a timing instruction. For example, the trigger circuit 104 may perform corresponding actions under the control of the control circuit 103 to form a timing command over time.
The first earpiece 20 and the second earpiece 30 may receive timing instructions. Specifically, when the first earphone 20 and the second earphone 30 are accommodated in the accommodating cavity 1010, the trigger circuit 104 is electrically connected to the first earphone 20 and the second earphone 30, respectively, so that the first earphone 20 and the second earphone 30 are accommodated in the accommodating cavity for receiving the timing instruction at the first time, and the first earphone 20 and the second earphone 30 can perform an operation corresponding to the timing instruction. For example, the first earphone 20 and the second earphone 30 may each be connected by contact contacts to achieve an electrical connection.
In this embodiment, the control circuit 103 controls the trigger circuit 104 to generate different timing instructions, and corresponding timing instructions are preset in the first earphone 20 and the second earphone 30, and when the timing instructions are received by the first earphone 20 and the second earphone 30, the timing instructions are matched with the preset timing instructions, and after the matching is successful, corresponding operations are performed, such as power on, power off, charging, connection between earphones and a mobile terminal, and the like.
This embodiment is through setting up control circuit 103 and trigger circuit 104 in earphone box subassembly 10, control circuit 103 can control trigger circuit 104 and produce the chronogenesis instruction, first earphone 20 and second earphone 30 can carry out corresponding operation receiving the chronogenesis instruction, thereby make first earphone 20 and second earphone 30 carry out different operations under the chronogenesis instruction of difference in order to realize different functions, can enrich the interaction between earphone and the earphone box subassembly 10, increase the variety of earphone box subassembly 10 to first earphone 20 and second earphone 30 control, thereby earphone box subassembly has been avoided among the prior art to the single function of charging of earphone, and the problem that other control action brought does not have.
As shown in fig. 2, the earphone box assembly 10 may further include an opening and closing sensing member 108. The opening and closing sensing hardware is used for sensing whether the box cover 102 is opened or closed. In this embodiment, the opening or closing of the cover 102 may refer to a closed state when the cover 102 covers the housing 101, or an open state when the cover 102 does not cover the housing 101. For example, the opening/closing sensor 108 is a mechanical switch, and when the box cover 102 is opened from the closed state, the mechanical switch can be switched from one state to another state, so as to trigger the control circuit 103 to perform some functions. Or the mechanical switch can detect that the box cover 102 is in the open state or the closed state, so that the control circuit 103 can be triggered or informed. For example, the opening/closing sensor 108 is a hall sensor, and can sense whether the cover 102 and the housing 101 are attached to each other to close the cover, or open the cover, so as to trigger the control circuit 103 to perform some functions. For example, the opening/closing sensor 108 is a light sensor, when the cover 102 is covered on the housing 101, the light inside is weak or no light is emitted, and when the cover 102 is opened, the light is strong, so that the control circuit 103 can be triggered to perform some functions.
The control circuit 103 may be in a sleep state or a low power consumption state when the box cover 102 is covered on the housing 101, which may save power, and of course, the control circuit 103 is in the sleep state, which does not mean that the earphone box assembly 10 may not perform other operations, such as charging the first earphone 20 and/or the second earphone 30. In this embodiment, the opening and closing sensing element 108 is coupled to the control circuit 103, and the opening and closing sensing element 108 may wake up the control circuit 103 when sensing that the box cover 102 is in the open state or switched from the closed state to the open state, so that the control circuit 103 may continue to perform other control operations. The open-close sensing part 108 is arranged to be linked with the control circuit 103, on one hand, the control circuit 103 can be conveniently waken up in a dormant state, on the other hand, the intelligent control of the earphone box assembly 10 can be conveniently achieved, and the control circuit 103 does not need to be manually waken up.
As shown in fig. 1, the earphone box assembly 10 may optionally include a battery (not labeled), disposed in the casing 101, and may provide power for the whole wireless earphone assembly 100, for example, power for the operations of the control circuit 103, the trigger circuit 104, the opening and closing sensor 108, the first earphone 20, and the second earphone 30. The battery may include a charging circuit for receiving an external power input to charge the battery and a power supply circuit. The power supply circuit is used to supply power to the headset and the entire headset case assembly 10.
As shown in fig. 2, in the present embodiment, the trigger circuit 104 may include a switch circuit 114 and a boost circuit 124. The switch circuit 114 is coupled to the control circuit 103. The boost circuit 124 is coupled to the control circuit 103 and the switch circuit 114. The voltage boosting circuit 124 may also be coupled to the battery for boosting the voltage provided by the battery under the control of the control circuit 103, for example, to a preset voltage to meet the charging requirements of the first earphone 20 and the second earphone 30. In the present embodiment, the preset voltage is 5V, for example.
In a specific scenario, when the control circuit 103 is in a sleep state or a low power consumption state, the opening/closing sensing element 108 senses that the box cover 102 is opened to wake up the control circuit 103 to operate normally, the control circuit 103 may control the boosting circuit 124 to be turned on, and the boosting circuit 124 performs boosting processing on the voltage supplied by the battery and outputs a preset voltage to the switch circuit 114.
The control circuit 103 is further configured to control the switch circuit 114 to open and close to form the preset voltage into the timing command. The boost circuit 124 provides a preset voltage to the switch circuit 114, and the switch circuit 114 can make the voltage output by the switch circuit 114 present in a high level and a low level through opening and closing operations, and can convert the voltage into a digital signal, i.e., present in a form of "0" and "1", for example, a voltage corresponding to "1" is 5V, and a voltage corresponding to 0 is 0V. The control circuit 103 controls the opening and closing operations of the switch circuit 114, and can form a timing signal, for example, "010111" or the like. Different timing signals can cause the headset to operate differently. Setting at least the switch circuit 114 and the boost circuit 124 as the trigger circuit 104 can make the earphone box assembly 10 conveniently and effectively generate timing instructions, thereby facilitating diversified control of the earphones, and setting the switch circuit 114 can facilitate control of operations such as charging the first earphone 20 and the second earphone 30. Due to the arrangement of the switch circuit 114, when the boost circuit 124 is turned on, the first earphone 20 and the second earphone 30 can also be controlled not to be charged, so that more dimensional control is realized, and more use scenarios are adapted.
In the present embodiment, the switch circuit 114 may have a discharge function (Load discharge). No matter in the process of forming the timing command or in the ordinary working process, when the switch circuit 114 is turned off, because the switch circuit has the discharging function, the residual charge can be effectively released from the high level to the low level, so that the effectiveness of the low level can be ensured, the effectiveness of the formation of the timing signal of the switch circuit 114 can be further ensured, and in addition, the time for the rise and the fall of the timing is ensured to be small enough.
As shown in fig. 1 and 2, the earphone box assembly 10 may optionally further comprise two first contacts 106 for coupling the first earphone 20 and two second contacts 107 for coupling the second earphone 30. The two first contacts 106 are respectively used as a positive pole and a negative pole, and one of the two first contacts 106 and one of the two second contacts 107, which are used as positive poles, are respectively coupled to the switch circuit 114 to receive the preset voltage output by the switch circuit 114. The other of the two first contacts 106 as a negative pole and the other of the two second contacts 107 as a negative pole may be grounded (i.e., as GND terminals).
The two first contacts 106 may be arranged to protrude from a wall of the receiving cavity 1010 corresponding to the first earphone 20, such as a bottom of the receiving cavity 1010, so that when the first earphone 20 is placed in the receiving cavity 1010, the first contacts 106 may contact with the corresponding contacts of the first earphone 20. The two second contacts 107 may also protrude from the cavity wall of the accommodating cavity 1010 corresponding to the second earphone 30, for example, the bottom of the accommodating cavity 1010, so that when the second earphone 30 is placed in the accommodating cavity 1010, the second contacts 107 can contact with the corresponding contacts of the second earphone 30 to achieve electrical connection. Of course, the earphone box assembly 10 may be wirelessly connected with the first earphone 20 and the second earphone 30, such as by means of a coil, for performing operations such as charging.
In this embodiment, the switch circuit 114 may be configured to short-circuit the two first contacts 106 and the two second contacts 107, respectively, when the switch circuit is opened, and since the other of the two first contacts 106 and the other of the two second contacts 107 is a ground terminal, a discharge function can be realized, and the potential of the switch circuit 114 is pulled down to the ground potential. The two first contacts 106 and the two second contacts 107 are controlled by the switch circuit 114 to be in short circuit, so that the discharging function can be well realized, the control is simple and convenient, and the reaction speed is high.
In this embodiment, the timing instruction includes a first timing instruction. For example, the first sequential instruction is 010111, which can be designed and defined according to specific situations. The first earphone 20 and the second earphone 30 are powered on when receiving the first timing command in the power-off state. The first earphone 20 and the second earphone 30 may be coupled to each other in the on state.
In a specific implementation scenario, when the first earphone 20 and the second earphone 30 are accommodated in the accommodating cavity 1010 and the box cover 102 is in a closed state, when the opening and closing sensing element 108 senses that the box cover 102 is opened, the control circuit 103 is waken up, the control circuit 103 turns on the voltage boosting circuit 124, and controls the opening and closing operations of the switch circuit 114 to form a first timing instruction, the first timing instruction is sent to the first earphone 20 and the second earphone 30 through the first contact 106 and the second contact 107, the first earphone 20 and the second earphone 30 are turned on, and the first earphone 20 and the second earphone 30 are connected after being turned on.
If use earphone box subassembly 10 output voltage constantly, first earphone 20 and second earphone 30 can not detect the start-up mode that voltage input carries out the start-up promptly after taking away earphone box subassembly 10, can make whole wireless earphone subassembly 100 the consumption bigger, can't accomplish in addition and carry out the effect of start-up promptly inside earphone box subassembly 10, still lead to the opening time consuming more in addition. In this embodiment, the earphone box assembly 10 can be powered on by the timing instruction, so that the user can be powered on in advance.
Of course, the timing instructions may also include a second timing instruction, and the first headset 20 and/or the second headset 30 performs the charging operation when receiving the second timing instruction. For example, the second timing instruction is "0111111" or "1111111".
The timing instructions may also include third timing instructions that the first earpiece 20 and/or the second earpiece 30 perform a power-off operation upon receiving the third timing instructions. For example, the third timing command is "0101011". Of course, the timing instructions may also comprise further sub-instructions for controlling the operation of the first earphone 20 and the second earphone 30, such as disconnecting the operation from the other earphone or disabling the charging operation, etc.
In this embodiment, when the cover 102 is covered on the housing 101 again from the open state, the opening/closing sensing element 108 senses that the cover 102 is switched from the open state to the closed state, and can trigger the control circuit 103 to control the switch circuit 114 to form a third timing instruction, so as to control the first earphone 20 and/or the second earphone 30 located in the accommodating cavity 1010 to perform a shutdown operation. For example, the time required from when the lid 102 is closed to when the first earphone 20 and/or the second earphone 30 is turned off may be, for example, only 2 seconds.
In this embodiment, the first earphone 20 and the second earphone 30 may have a main pair. Generally, the main earphone can be in communication connection with an external device such as a mobile terminal, the auxiliary earphone is connected with the main earphone, and the main earphone can synchronize at least part of information sent by the mobile terminal to the auxiliary earphone, so that the main earphone and the auxiliary earphone can be used in combination. The main earphone can transmit audio to an external device such as a mobile terminal, for example, the audio is input through a microphone of the main earphone to be transmitted to the external device such as the mobile terminal.
In a specific application scenario, when the wireless headset assembly 100 of the present embodiment is used for the first time, the first earphone 20 and the second earphone 30 do not distinguish between a main earphone and a sub-earphone, and the earphone that is taken away from the accommodating cavity 1010 first can be used as the main earphone, and the earphone that is left in the accommodating cavity 1010 or is taken away from the accommodating cavity 1010 later can be used as the sub-earphone. For example, the first earphone 20 and the second earphone 30 are in the on state, for example, the first earphone 20 and the second earphone 30 are in the on state after receiving the first timing command, the first earphone 20 is first taken out of the accommodating cavity 1010, that is, the first earphone 20 cannot detect the preset voltage input, and the second earphone 30 can still detect the preset voltage input when the first earphone 20 is taken out, so that the first earphone 20 can be triggered to be used as a main earphone, and the second earphone 30 can be triggered to be used as a sub-earphone. The primary and secondary may be determined, for example, by communication and handshaking protocols between the first headset 20 and the second headset 30.
In this embodiment, the primary and secondary earpieces can be switched. For example, the first earphone 20 is used as a primary earphone, the second earphone 30 is used as a secondary earphone, and both the first earphone 20 and the second earphone 30 are in the on state. When the second earphone 30 does not detect the preset voltage input and the first earphone 20 detects the preset voltage input, the first earphone 20 and the second earphone 30 perform main-auxiliary switching, so that the first earphone 20 is switched to be the auxiliary earphone and the second earphone 30 is switched to be the main earphone.
Specifically, when the second earphone 30 does not detect the input of the preset voltage and the first earphone 20 detects the input of the preset voltage, for example, the second earphone 30 is taken away from the earphone box assembly 10 and cannot detect the input of the preset voltage, the first earphone 20 can still detect the input of the preset voltage in the earphone box assembly 10, the second earphone 30 as the secondary earphone sends the switching request to the first earphone 20, and the first earphone 20 as the primary earphone sends the feedback information to the second earphone 30 after receiving the switching request. For example, the switching request is used to request the first earphone 20 to switch to the secondary earphone, the first earphone 20 forms feedback information after receiving the switching request, the feedback information indicates that the second earphone 30 can be switched to the primary earphone, and the switching request and the feedback information can pass through a handshake protocol, so that the first earphone 20 and the second earphone 30 can perform primary-secondary switching.
Of course, if the main earphone is taken out of the earphone box assembly 10, i.e., the main earphone does not detect the input of the preset voltage, and the sub-earphone remains in the earphone box assembly 10, i.e., the sub-earphone detects the input of the preset voltage, the main and sub-earphones may not need to be switched.
In other embodiments, it may be detected that the main earphone is located in the earphone box assembly 10 through the earphone box assembly 10, and the auxiliary earphone is not located in the earphone box assembly 10, the control circuit 103 may control the switch circuit 114 to form a corresponding timing instruction, send the timing instruction to the main earphone to notify the main earphone of switching to the auxiliary earphone, and send a switching request to the auxiliary earphone to notify the auxiliary earphone of switching to the main earphone, so that the main-auxiliary switching of the first earphone 20 and the second earphone 30 may also be implemented.
As shown in fig. 2, optionally, the headphone cartridge assembly 10 further includes a detection circuit 105. The detection circuit 105 is coupled to the control circuit 103. The detection circuit 105 is further configured to detect a current value of the current output from the switch circuit 114 to the first earphone 20 and/or the second earphone 30. The detection circuit 105 may further return the current value to the control circuit 103 to facilitate the control circuit 103 to perform corresponding processing and operations. In this embodiment, the detection circuit 105 may detect a current value of the current outputted from the switch circuit 114 to the first earphone 20, may detect a current value of the current outputted from the switch circuit 114 to the second earphone 30, or may detect that the detection circuit 105 is further configured to detect current values of the currents outputted from the switch circuit 114 to the first earphone 20 and the second earphone 30, respectively.
As shown in fig. 1, in the present embodiment, if the first earphone 20 and the second earphone 30 are not placed in the accommodating chamber 1010, the output current of the switching circuit 114 to the first earphone 20 and the second earphone 30 is actually zero, and therefore it can be considered that there is no output current, and the control circuit 103 may not perform a control operation. Of course, if neither the first earphone 20 nor the second earphone 30 is placed in the accommodating cavity 1010, the control circuit 103 may also control the step-up circuit 124 to be turned off, so as to save power.
For example, the control circuit 103 controls the switch circuit 114 to form a second timing command, such as "0111111". When the first earphone 20 and/or the second earphone 30 is accommodated in the corresponding accommodating cavity 1010, the second timing instruction may be received, the first earphone 20 and/or the second earphone 30 performs a charging operation, a current flows from the switch circuit 114 to the first earphone 20 and/or the second earphone 30, flows in a current loop formed, the detection circuit 105 may detect a charging current in the loop, and the control circuit 103 may determine which state of the earphone is being charged, such as a high-speed charging state, a slow-speed charging state, and a full state, according to the charging current value.
For example, the detection circuit 105 is used to detect whether the current value of the charging current of the first earphone 20 and/or the second earphone 30 is smaller than a preset value. When the current value of the charging current of the first earphone 20 and/or the second earphone 30 is smaller than the preset value, that is, the battery of the first earphone 20 and/or the second earphone 30 is fully charged. Of course, in the present embodiment, the control circuit 103 may turn off the boost circuit 124 as long as either one of the first earphone 20 and the second earphone 30 is fully charged, or both the current values of the charging currents of the first earphone 20 and the second earphone 30 are smaller than the preset value, and the control current turns off the boost current.
Specifically, the detection circuit 105 is coupled to one of the two first contacts 106 as a negative pole and one of the two second contacts 107 as a negative pole, respectively. Current flows from the switching circuit 114 to the first earpiece 20 through one of the two first contacts 106 that is positive and out of one of the two first contacts 106 that is negative. The current flows from the switching circuit 114 to the second earphone 30 through one of the two second contacts 107 as the positive pole and flows out from one of the two second contacts 107 as the negative pole.
The detection circuit 105 turns off the voltage boosting circuit 124 by the control circuit 103 when the detection circuit 105 detects that the current value of one of the two first contacts 106 as the negative pole and/or the current value of one of the two second contacts 107 as the negative pole is smaller than a preset value.
In the present embodiment, the preset value may be 0.1C, where C is the capacity of the battery of the first earphone 20 or the second earphone 30.
In the embodiment, by setting the detection circuit 105, when the current value of the current output from the switch circuit 114 to the first earphone 20 and/or the second earphone 30 is smaller than the preset value, or the current value of the charging current of the first earphone 20 and/or the second earphone 30 is smaller than the preset value, the control circuit 103 can control the step-up circuit 124 to be turned off, that is, even if the first earphone 20 and the second earphone 30 are located in the earphone box assembly 10, as long as the current detected by the detection current satisfies the relevant condition, the step-up circuit 124 can be turned off, so that the electric quantity can be effectively saved, the service life of the wireless earphone can be prolonged, and the service lives of the earphone box assembly 10 and the battery of the earphone can be prolonged.
In this embodiment, for example, when the first earphone 20 and/or the second earphone 30 is placed in the accommodating cavity 1010, the control circuit 103 may be triggered to control the switch circuit 114 to form a second timing command, so that the first earphone 20 and/or the second earphone 30 enters a charging state, and when the detection circuit 105 detects that the first earphone 20 and/or the second earphone 30 is fully charged, the control circuit 103 controls the voltage boosting circuit 124 to turn off. When the first earphone 20 and/or the second earphone 30 is taken out of the earphone box assembly 10 and then placed in the accommodating cavity 1010 again, the above process is repeated again to enter the charging state.
Of course, in other embodiments, for example, when the first earphone 20 and/or the second earphone 30 are placed in the receiving cavity 1010 and the opening/closing sensor 108 senses that the lid 102 is in the closed state, the control circuit 103 is triggered to control the switch circuit 114 to form a second timing command, so as to control the first earphone 20 and/or the second earphone 30 to enter the charging state. In this way, only placing the first earphone 20 and/or the second earphone 30 in the receiving cavity 1010 may not trigger the control circuit 103 to control the switch circuit 114 to generate the second timing command. Of course, there are various ways for the trigger control circuit 103 to control the switch circuit 114 to form the second timing command, and the method is not limited herein.
In an application scenario, for example, when the first earphone 20 and/or the second earphone 30 are placed in the accommodating cavity 1010 and the opening/closing sensor 108 senses that the cover 102 is switched from the open state to the closed state, the control circuit 103 is triggered to control the switch circuit 114 to form a third timing instruction, so as to control the first earphone 20 and the second earphone 30 to be powered off, and then or simultaneously, the control circuit 103 is triggered to control the switch circuit 114 to form a second timing instruction, so as to control the first earphone 20 and/or the second earphone 30 to be charged. After the first earphone 20 and the second earphone 30 are powered on, the open/close sensing element 108 may wake up the control circuit 103 and the control circuit 103 may control the switch circuit 114 to be powered on if the lid 102 is opened again after the boost circuit 124 is fully charged, or as described above, the control circuit 103 may control the switch circuit 114 to form a first timing command to control the first earphone 20 and the second earphone 30 to be powered on after the boost circuit 124 is powered on. After the first earphone 20 and the second earphone 30 are powered on, main-auxiliary switching and the like can be performed under corresponding conditions.
In other application scenarios, after the boost circuit 124 is turned off, if the headphone box assembly 10 receives an external power input or if the battery of the headphone box assembly 10 receives an external power input when the battery capacity is less than 10%, the control circuit 103 may also be awakened, and the control circuit 103 may control the boost circuit 124 to be turned on.
