Detailed Description

As shown in fig. 1, fig. 1 is a schematic structural diagram of an earphone device according to an embodiment of the present application. Embodiments of the present disclosure provide an earphone device, such as the earphone device 10, the earphone device 10 may include an earphone box, such as the earphone box 20, and a wireless earphone, such as the wireless earphone 40, wherein the earphone box 20 may be configured to store the earphone box of the wireless earphone 40. Wherein wireless headset 40 refers to a very small headset designed to fit directly into the user's ear. The wireless headset 40 may be referred to as an in-ear headphone or an earbud headphone, which includes a small headset that fits inside the outer ear of the user without being inserted into the ear canal, and an in-ear headphone, sometimes referred to as an in-canal headphone, that is inserted into the ear canal itself. The wireless headset 40 may be a bluetooth headset, and the bluetooth headset may establish a connection with the mobile terminal through a bluetooth communication signal to transmit a sound signal of the mobile terminal. It should be noted that the wireless headset 40 is not limited to a bluetooth headset, and may be other types of headsets.

The wireless headset 40 is provided with one or more detection ports such as a detection port 41, and the detection port 41 may output an electrical signal such as a voltage signal or a current signal. The detection port 41 may be provided on a surface of the wireless headset 40, and when the wireless headset 40 is put into the headset case 20, the detection port 41 may be in contact with and electrically connected to the headset case 20. Earphone box 20 may be configured to detect the electrical signal and perform corresponding operations according to the value of the electrical signal, such as a box-in detection operation, a box-out detection operation, or a charging operation.

As shown in fig. 2 and 3, fig. 2 is a first structural schematic diagram of a headphone case in the headphone apparatus shown in fig. 1, and fig. 3 is a second structural schematic diagram of the headphone case in the headphone apparatus shown in fig. 1. Earphone pod 20 includes a pod such as pod 100, and pod 100 may be formed from plastic, ceramic, fiber composite, other suitable materials, or a combination of any two or more of these materials. The cartridge 100 may be formed using a one-piece configuration in which some or all of the cartridge 100 is machined or molded as a single structure, or may be formed using multiple structures (e.g., an inner frame structure, one or more structures that form an outer housing surface, etc.). Case 100 may serve as a carrier for earphone box 20 and may carry components of earphone box 20, such as a processor, a power supply, etc.

The case 100 may be provided with one or more receiving grooves 120, and the receiving grooves 120 may be used to receive the wireless headset 40. The receiving slot 120 may be sized and shaped to match the size and shape of the wireless headset 40. The receiving groove 120 may have a regular shape, such as a cylindrical structure or a rectangular parallelepiped structure, and the receiving groove 120 may also have an irregular shape.

For example, the case 100 may be provided with two receiving grooves 120, a first receiving groove and a second receiving groove, respectively, the first receiving groove may be used for receiving one earphone of the pair of wireless earphones 40, such as a left-ear earphone, and the second receiving groove may be used for receiving the other earphone of the wireless earphones 40, such as a right-ear earphone. The size and shape of the first accommodating groove are matched with those of the left-ear earphone, and the size and shape of the second accommodating groove are matched with those of the right-ear earphone.

Earphone box 20 may also include a detection circuit such as detection circuit 200, and detection circuit 200 may be used to detect the voltage signal output by port 41. The detection circuit 200 may be disposed on the cartridge 100, for example, the detection circuit 200 may be disposed on a surface of the cartridge 100 or disposed inside the cartridge 100. For example, the box 100 may be provided with a mounting groove, the detection circuit 200 may be disposed in the mounting groove, and the mounting groove may be covered by a mounting plate, so that the detection circuit 200 is not visible from the outside of the box 100. In some embodiments, when the detection circuit 200 is disposed inside the box 100, a through hole may be formed on the surface of the box 100, and the detection pin of the detection circuit 200 is inserted into the through hole to be exposed on the surface of the box 100.

Referring to fig. 4 and 5, fig. 4 is a schematic structural diagram of a wireless headset in the headset device shown in fig. 1. Fig. 5 is a view of the application of the wireless headset to the headset box in the headset device shown in fig. 1. When the wireless headset 40 is placed in the receiving groove 120, the detection port 41 of the wireless headset 40 is in contact with and electrically connected to the detection pin, and the detection circuit 200 detects whether the detection port 41 outputs a voltage signal through the detection pin.

Earphone box 20 may further include a first processor, such as first processor 300, where first processor 300 is configured to control devices inside earphone box 20 as a control center of earphone box 20. The first processor 300 may be disposed on the cartridge 100, for example, the first processor 300 may be disposed on a surface of the cartridge 100 or inside the cartridge 100. The first processor 300 is electrically connected to the detection circuit 200, and the first processor 300 may be configured to determine whether the detection circuit 200 detects the first voltage signal, and determine that the wireless headset 40 is accommodated in the accommodating slot 120 when the detection circuit 200 detects the first voltage signal, so as to implement the in-box detection of the wireless headset 40.

For example, when the user opens the cover of the earphone box 20, the first processor 300 may control the detection circuit 200 to be in an operating state, and the detection circuit 200 may be configured to detect the first voltage signal output by the detection port 41 of the wireless earphone 40 when in the operating state. The detection circuit 200 may send the detection result to the first processor 300, and after the first processor 300 receives the detection result, the first processor 300 determines the detection result of the detection circuit 200 to determine whether the detection circuit 200 detects the first voltage signal, and performs different operations according to the determination result. For example, the wireless earphone 40 can control the detection port 41 to output the first voltage signal when the wireless earphone 40 is not accommodated in the accommodating slot 120, so that the detection circuit 200 can directly detect the first voltage signal output by the detection port 41 when the wireless earphone 40 is accommodated in the accommodating slot 120. The first voltage signal output by the wireless headset 40 may also be sent by controlling the wireless headset 40 by a user, for example, when the wireless headset 40 is connected to a mobile terminal, the user may operate the wireless headset 40 by operating on the mobile terminal, so that the detection port 41 outputs the first voltage signal.

When the detection circuit 200 detects the first voltage signal as a result of the determination, it is determined that the wireless headset 40 has been placed into the receiving slot 120. In some embodiments, first processor 300 may be further configured to control earphone box 20 to issue a box reminder message after determining that wireless earphone 40 has been placed into receiving slot 120, indicating to the user that wireless earphone 40 has been successfully placed into receiving slot 120. For example, the first processor 300 may control the earphone box 20 to emit a first prompt sound for reminding the user that the wireless earphone 40 is placed in the earphone box 20, and after receiving the first prompt sound, the user may close the cover of the earphone box 20 to enclose the wireless earphone 40 in the box 100.

When the first voltage signal is not detected by the detection circuit 200 as a result of the determination, there may be various situations. For example, the wireless earphone 40 is not placed in the receiving slot 120, or the wireless earphone 40 is not placed in a preset position of the receiving slot 120, for example, the left earphone is placed in the second receiving slot or the detection port 41 of the wireless earphone 40 is not placed corresponding to the detection circuit 200, so that the first detection circuit 200 does not detect the first voltage signal, and the detection circuit 200 may be damaged to fail to detect the first voltage signal. The above is merely an example of the case where the detection circuit 200 does not detect the presence of the first voltage signal, and is not to be construed as a limitation of the possible case where the detection circuit 200 does not detect the presence of the first voltage signal.

This application embodiment is through setting up detection circuitry 200 in earphone box 20 and in order to detect the first voltage signal that wireless headset 40 output, whether confirm that wireless headset 40 is accomodate in accomodating groove 120 through detecting first voltage signal to detection circuitry 200, for prior art, this application embodiment can realize wireless headset 40's income box and detect without additionally setting up other sensors in wireless headset 40.

In some embodiments, the first processor 300 may control the detection circuit 200 to switch between an active state and an off state, wherein the off state refers to a state without operation, such as a standby state. The first processor 300 may control the detection circuit 200 to switch from the operating state to the off state when it is determined that the wireless headset 40 has been placed in the receiving slot 120 or that the wireless headset 40 has left the receiving slot, so as to save power consumption of the headset case 20.

With continued reference to fig. 2 and 3, the earphone box 20 is further provided with a power source such as a power source 400 for providing an electrical signal, the power source 400 may be disposed on the box body 100, for example, the power source 400 may be disposed on a surface of the box body 100, such as a bottom wall surface of the receiving groove 120, and when the wireless earphone 40 is placed in the receiving groove 120, the power source 400 may be electrically connected to the detection port 41 and charge the wireless earphone 40 through the detection port 41. For another example, the power source 400 may be disposed inside the case 100, such as the power source 400 may be disposed in a bottom wall for forming the receiving groove 120 or a side wall for forming the receiving groove 120, and one or more detection pins are disposed on the surface of the case 100, and electrically connected to the detection port 41 through the detection pins to charge the wireless headset 40. For example, the detection circuit 200 may include a first pin 210 and a second pin 220, wherein one end of the first pin 210 is used for connecting with the first processor 300, and the other end of the first pin 220 is used for connecting with the wireless headset 40. One end of the second pin 220 is grounded, and the other end of the second pin 220 is used for connecting with the wireless headset 40. For example, the detection port 41 may include two sub-ports, for example, the detection port 41 includes a first port 411 and a second port 411, one end of the second port 411 is grounded, the first port 411 is connected to the first pin 210, the second port 412 is connected to the second pin 220, and a current signal output by the power supply 400 is transmitted to the first port 411 through the first pin 210 and transmitted to the second pin 220 through the second port 412 to form a current loop, so as to complete charging of the wireless headset 40. It should be noted that the detection circuit 200 may include other numbers of pins, such as three pins, four pins, etc.

The earphone box 20 is further provided with a first switch such as a first switch 500, one end of the first switch 500 is connected with the detection circuit 200, and the other end of the first switch 500 may be switchably connected between the first processor 300 and the power supply 400. The first processor 300 may control the first switch 500. For example, in the initial state, the first switch 500 is electrically connected to the first processor 300. After determining that the wireless headset 40 is accommodated in the accommodating slot 120, the first processor 300 controls the other end of the first switch 500 to be disconnected from the first processor 300, and the other end of the first switch 500 is electrically connected to the power supply 400, and controls the power supply 400 to charge the wireless headset 40.

For example, when the first processor 300 determines that the wireless headset 40 has been placed in the receiving slot 120, the first processor 300 obtains the detection structure of the detection circuit 200, determines whether the detection circuit 200 detects the first voltage signal, and if it is determined that the detection circuit 200 detects the first voltage signal, it indicates that the wireless headset 40 has been placed in the receiving slot 120 and the detection port 41 is successfully electrically connected to the power supply port of the power supply 400, and at this time, the first processor 300 may control the power supply 400 to output an electrical signal to charge the wireless headset 40. If the detection circuit 200 does not receive the first voltage signal, the charging operation is not performed. In the embodiment of the present application, the detection port 41 of the wireless headset 40 is used as a charging port, and the power supply 400 can directly transmit an electrical signal to the wireless headset 40 through the detection port 41, so as to charge the wireless headset 40.

Referring to fig. 6, fig. 6 is a schematic structural diagram of the earphone box of the earphone device shown in fig. 1 for charging the wireless earphone. The wireless earphone 40 further includes a battery such as a battery 42 and a second switch such as a second switch 49, one end of the second switch 49 is connected to the detection port 41, and the other end of the second switch 49 is connected to the second processor 44 and the battery 49, so that the battery 42 is electrically connected to the detection port 41 through the second switch 49, and the battery 42 can output a voltage (discharging operation) through the detection port 41, for example, the battery 42 can output a first voltage signal through the detection port 41.

Alternatively, the battery 42 may only input voltage and not output voltage, for example, the earphone box 20 may be additionally provided with a power supply, for example, a 5V dc power supply, which is connected to the detection port 41 and outputs a preset voltage signal, for example, the first voltage signal, through the detection port 41.

The battery 42 can also input a voltage through the detection port 41 (charging operation). When the detection circuit 200 is electrically connected to the detection port 41, the detection circuit 200 may be further configured to detect a second voltage signal output by the wireless headset 40, where the second voltage signal may be used to reflect a power state of the wireless headset 40. The first processor 300 may be further configured to obtain a second voltage signal from the detection circuit 200 when the power supply 400 charges the wireless headset 40, and adjust a rate at which the power supply 400 charges the wireless headset 40 according to a magnitude of the second voltage signal.

For example, when the power supply 400 charges the wireless headset 40, to adjust the charging rate of the power supply 400 for the wireless headset 40, the wireless headset 40 may output a second voltage signal, which may be automatically sent by the wireless headset 40, for example, the detection circuit 200 may obtain the state of charge of the battery 42 through the detection port 41, and the state of charge may be a current charge value or a to-be-charged value. After detecting the second voltage signal, the detection circuit 200 sends the detected second voltage signal to the first processor 300, and after receiving the second voltage signal, the first processor 300 determines whether the charging rate needs to be adjusted according to the second voltage signal. For example, a threshold may be preset, and when the second voltage signal is less than or equal to the threshold, the first processor 300 may increase the charging rate of the power supply 400; when the second voltage signal is greater than the threshold, the first processor 300 may decrease the charge rate of the power supply 400, or not operate, or maintain the current charge rate, etc.

It should be noted that the adjustment method of the charging rate is not limited to this, for example, the charging rate of the power supply 400 may be controlled by the user, for example, when the user needs to use the wireless headset 40 urgently and the electric quantity of the wireless headset 40 is low, the user may send an instruction to increase the charging rate, and after receiving the instruction, the first processor 300 may control the power supply 400 to increase the charging rate of the wireless headset 40 to charge the wireless headset 40 quickly.

Of course, when the detection circuit 200 detects the second voltage signal, the first processor 300 may also increase the rate of charging the wireless headset 40 by the power supply 400 according to the second voltage signal and then decrease the rate of charging the wireless headset 40 by the power supply 400, or the first processor 300 may first decrease the rate of charging the wireless headset 40 by the power supply 400 and then increase the rate of charging the wireless headset 40 by the power supply 400 according to the second voltage signal. For example, the first processor 300 may first reduce the rate at which the power supply 400 charges the wireless headset 40, determine whether the electrical signal output by the power supply 400 is successfully input into the wireless headset 40, and increase the rate at which the power supply 400 charges the wireless headset 40 when it is determined that the wireless headset 40 can be normally charged. It should be noted that the charging rate for adjusting the power supply 400 to charge the wireless headset 40 is not limited to this, and may be adjusted according to actual situations, such as increasing the charging rate, decreasing the charging rate, and then increasing the charging rate.

In some embodiments, when the electric quantity value of the battery 42 reaches the preset value, the first processor 300 may control the power supply 400 to stop charging the battery 42, for example, the first processor 300 may control the first switch 500 to be disconnected from the power supply 400 to stop charging. In order to monitor whether the wireless headset 40 is taken out of the receiving slot 120, the first processor 300 may control the other end of the first switch 500 to be connected to the first processor 300, so that the detection circuit 200 is connected to the first processor 300 through the first switch 500. At this time, the detection circuit 200 may be configured to detect a current voltage signal of the wireless headset 40, such as a third voltage signal, where a value of the third voltage signal may be equal to a value of the second voltage signal, or may not be equal to the value of the second voltage signal. When the wireless earphone 40 is not out of the receiving slot 120, the detection circuit 200 is connected to the detection port 41 of the wireless earphone 40, and can detect the third voltage signal; when the wireless headset 40 leaves the receiving slot 120, the detection port 41 of the wireless headset 40 is disconnected from the detection circuit 200, so that the detection circuit 200 cannot detect the third voltage signal, and at this time, the detection circuit 200 may send a detection structure to the first processor 300, and the first processor 300 may determine that the wireless headset 40 has left the receiving slot 120 according to the detection result.

As shown in fig. 3, the cartridge 100 may also be provided with one or more indicators such as indicator 600, and the indicator 600 may be provided on an outer surface of the cartridge 100, where the outer surface is the side of the cartridge 100 that is visible from the outside when viewed from the outside of the cartridge 100. The indicator 600 may be used to indicate the state of charge of the power supply 400 and/or the wireless headset 40 so that the user can intuitively know the state of charge of the power supply 400 and/or the wireless headset 40 on the outer surface of the cartridge 100. For example, the cartridge 100 may include three indicators 600, one indicator 600 for indicating the power status of the power supply 400 and two other indicators 600 for indicating the power status of the wireless headset 40. One of the indicators 600 may include a plurality of indicator lights (e.g., four indicator lights), and when the power of the power supply 400 or the wireless headset 40 is 0% to 25%, one of the four indicator lights is in a light-on state, and the other three indicator lights are in a light-off state; when the electric quantity of the power supply 400 or the wireless earphone 40 is 25% -50%, two indicator lights of the four indicator lights are in a light-on state, and the other two indicator lights are in a light-off state; when the electric quantity of the power supply 400 or the wireless earphone 40 is 50% -75%, three indicator lights of the four indicator lights are in a light-on state, and the other three indicator lights are in a light-off state; when the power supply 400 or the wireless earphone 40 has 75% -100% of the electric quantity, all four indicator lights are in the light state. As another example, an indicator may include only one indicator light that may display different colors to indicate several different power states of the power supply 400 or the wireless headset 40.

As shown in fig. 3 and 7, fig. 7 is a schematic structural diagram of the earphone box and the wireless earphone in the earphone device shown in fig. 1, the earphone box 20 may further include a first control circuit such as a first control circuit 700, the first control circuit 700 is electrically connected to the first processor 300, and the first control circuit 700 may be electrically connected to the detection circuit 200 through the first switch 500. It is understood that the other end of the first switch 500 may switch the connection between the first processor 300, the power supply 400 and the first control circuit 700. The first control circuit 700 is configured to control the detection circuit 200 to output a first preset level signal, where the first preset level signal is used for communicating with the wireless headset 40. For example, the first preset level signal may be a value indicating that the wireless headset 40 transmits the electric quantity of the battery 42, or information indicating that the wireless headset 40 transmits whether the battery 42 is successfully charged.

For example, when the detection circuit 200 detects that the value of the second voltage signal is greater than or equal to the threshold, the first processor 300 may control the other end of the first switch 500 to disconnect from the power supply 400, and switch to the first control circuit 700, so that the first control circuit 700 is electrically connected to the detection circuit 200, the first control circuit 700 controls the detection circuit 200 to output a first preset level signal, where the first preset level signal is a preset voltage signal, for example, the first preset level signal may be a preset level change signal. The first preset level signal may be input into the processor of the wireless headset 40 through the detection port 41, and after receiving the first preset level signal, the processor of the wireless headset 40 may respond to the first preset level signal to transmit corresponding information to the first processor 300. Such as feeding back information about the current charge value of the battery 42 (such as the current charge amount is 25% or the current charge amount is 100%), or whether the battery 42 is successfully charged currently, to the first processor 300. For additionally adding a communication module, in the embodiment of the present application, the first control circuit controls the detection circuit 200 to output the first preset level signal, and the transmission of the first preset level signal is performed through the electrical connection between the detection circuit 200 and the detection port 42, so that the communication between the wireless headset 40 and the headset box is realized without additionally adding a communication module.

In some embodiments, the first control circuit 700 may be omitted from the earphone box 20, and alternatively, the first processor 300 directly controls the detection circuit 200 to output the first preset level signal and use the first preset level signal for communicating with the wireless earphone 40.

Referring to fig. 2, the earphone box 20 may further include a cover body such as a cover body 800, and the cover body 800 may be connected to the box body 100. For example, the cover 800 may be detachably connected to the case. When the user needs to take out the wireless headset 40, the cover 800 is separated from the case 100, so that the wireless headset 40 received in the receiving groove 120 is exposed to the outside, and the user can take out the wireless headset 40 exposed to the outside from the receiving groove 120. When a user needs to hide the wireless headset 40 in the headset box 20, the cover 800 may be connected to the box 100, and the cover 800 may enclose the wireless headset 40 inside the headset box 20.

The cover 800 is provided with a cover sensor such as cover sensor 820, and the cover sensor 820 may be used to detect when the cover 800 is in an open state and when the cover 800 is in a closed state. The lid sensor 820 may be electrically connected with the first processor 300 so that the first processor 300 may receive signals from the lid sensor 820 indicating when the lid 800 is in the open state and when in the closed state. For example, the cover sensor 820 may generate and transmit an opening signal to the first processor 300 upon detecting when the cover body 800 is in an opened state. The first processor 300 may be configured to communicate with the wireless headset 40 to trigger the wireless headset 40 to turn on its wireless communication device, such as a bluetooth communication device, when the first processor 300 receives the turn-on signal, so that it may automatically establish a connection with the mobile terminal for use by the user. The cover sensor 820 may generate and transmit a closing signal to the first processor 300 upon detecting when the cover body 800 is in a closed state. The first processor 300 may trigger the wireless headset 40 to shut down when receiving the close signal to conserve power of the wireless headset 40. Wherein the lid sensor 820 may be any type of mechanical or electrical switch including, but not limited to, a momentary switch, a capacitive sensor, a magnetic sensor, or an optical sensor, among others.

The first processor 300 may be further configured to determine whether the detection circuit 200 is connected to the first processor 300 when receiving a detection signal (such as the opening signal or the closing signal described above); if the detection circuit 200 is not connected to the first processor 300, the other end of the first switch 500 is controlled to be connected to the first processor 300, so that the detection circuit 200 is connected to the first processor 300.

Fig. 8 is a third structural diagram of the earphone case of the earphone device shown in fig. 1, as shown in fig. 8. The cover 800 of the embodiment of the present application may be rotatably connected to the box 100 so that the cover 800 may be switched between a closed state and an open state, the open state of the cover 800 refers to a state in which the receiving groove 120 is exposed, and the closed state refers to a state in which the receiving groove 120 is enclosed in the box 100. It is understood that when the cover 800 is in the closed state, the cover 800 is aligned over the one or more receiving grooves 120 in the closed position of the cover 800 and the case 100, thereby enclosing the wireless headset 40 placed in the receiving groove 120 within the case; when the cover 800 is in the open state, the receiving groove 120 is exposed to the outside so that the user can take out or replace the wireless headset 40 in the receiving groove 120.

Continuing to refer to fig. 2, the wireless headset 40 may be provided with a speaker, such as speaker 43, and the speaker 43 may emit an acoustic signal through an acoustic emission port, such as acoustic emission port 431. Earphone box 20 may be configured to receive the sound signal and perform corresponding operations according to the type of the sound signal, such as a box-in detection operation, a box-out detection operation, or a charging operation. Correspondingly, the cartridge 100 is further provided with a sound receiver such as the first sound receiver 900, and the first sound receiver 900 can be used for receiving a preset sound signal emitted by the wireless headset 40. The first sound receiver 900 may be a microphone or other sound receiving device. The first sound receiver 900 may be provided on the case 100, for example, the first sound receiver 900 may be provided on a surface of the case 100, or provided inside the case 100. In some embodiments, when the first sound receiver 900 is disposed inside the box body 100, a sound receiving hole may be opened on a surface of the box body 100, so that a predetermined sound signal emitted from the wireless headset 40 may be transmitted to the first sound receiver 900 through the sound receiving hole to improve a sound receiving effect of the first sound receiver 900.

In some embodiments, the first processor 300 may be configured to control the first sound receiver 900 to be in an operating state when the detection circuit 200 does not detect the first voltage signal, determine whether the first sound receiver 900 receives a predetermined sound signal, and determine that the wireless headset 40 is received in the receiving slot 120 when the first sound receiver 900 receives the predetermined sound signal.

For example, the detection circuit 200 may send an instruction that the first voltage signal is not detected to the first processor 300 when the first voltage signal is not detected, and when the first processor 300 receives the instruction that the first voltage signal is not detected, may control the one or more first sound receivers 900 to start up, and the first sound receivers 900 may receive the preset sound signal after starting up. In the embodiment of the present application, the sound receiver is started to receive the preset sound signal, so as to prevent the detection circuit 200 from not detecting the first voltage signal because the detection port 41 of the wireless headset 40 is not disposed corresponding to the detection pin of the detection circuit 200. For another example, the first processor 300 may also control the first sound receiver 900 to start when no instruction of the detection circuit 200 is detected within a preset time period, so as to prevent the detection circuit 200 from being damaged, which may cause that the first voltage signal cannot be detected and an instruction cannot be sent to the first processor 300. Of course, the first processor 300 may also control the detection circuit 200 to be in the inactive state when the first sound receiver 900 is activated, so as to prevent the detection circuit 200 from being in the active state all the time and consuming the power of the power supply 400, thereby prolonging the power usage time of the power supply 400.

Fig. 9 is a fourth structural diagram of the earphone case of the earphone device shown in fig. 1, as shown in fig. 9. The earphone box 20 may further include a rotation member such as the rotation member 1010 and a first driving mechanism such as the first driving mechanism 1110, the rotation member 1010 being disposed in the receiving groove 120, for example, the rotation member 1010 may be disposed on a bottom wall for forming the receiving groove 120. The rotation member 1010 is rotatably coupled to the casing 100, for example, the rotation member 1010 may be rotatably coupled to the casing 100 via a first coupling member, and the first driving mechanism 1110 may drive the rotation member 1010 to rotate around the first coupling member, so that the wireless headset 40 placed in the receiving slot 120 follows the rotation member 1010 to rotate. The first driving mechanism 1110 is further electrically connected to the first processor 300, and the first processor 300 can be used to control the first driving structure 810 to drive the rotating member 1010 to rotate.

The rotation member 1010 is provided with a positioning structure, which can be used to position whether the sound emitting end 431 of the wireless headset 40 corresponds to the first sound receiver 900, the positioning structure can be a mechanical structure or an electronic structure, such as a positioning post formed on the rotation member 1010, the positioning structure can be a sensor, such as an optical sensor, and the optical sensor can be used to emit a light signal. The first processor 300 may be further configured to detect whether the positioning structure is located at a predetermined position when the wireless headset 40 is received in the receiving slot 120 and the first sound receiver 900 does not receive a predetermined sound signal; if the positioning structure is not located at the predetermined position, the first driving mechanism 1110 is controlled to drive the rotating member 1010 to rotate so that the positioning structure rotates to the predetermined position, and the sound emitting end 431 of the wireless headset 40 corresponds to the first sound receiver 900.

For example, the earphone box 20 may be provided with a detector electrically connected to the first processor 300, the detector may be configured to detect whether the positioning structure is located at a preset position, and when the detector detects that the positioning structure is not located at the preset position, the detector may send a first instruction to the first processor 300, and after the first processor 300 receives the first instruction, the first driving mechanism 1110 is controlled to drive the rotating member 1010 to rotate to the preset position. For example, during the rotation of the first driving mechanism 1110, the detector may detect the position of the positioning structure in real time, when it is detected that the positioning structure has rotated to the preset position, the detector may send a second instruction to the first processor 300, and after receiving the second instruction, the first processor 300 controls the first driving mechanism 1110 to stop operating, so as to stop rotating the rotating member 1010. At this time, the positioning structure is located at the predetermined position, and the sound receiving end of the wireless headset 40 corresponds to the first sound receiver 900, so as to reduce the distance between the sound receiving end of the wireless headset 40 and the first sound receiver 900, and improve the box-entering detection accuracy of the wireless headset 40.

Fig. 10 is a schematic diagram of a fifth structure of the earphone case of the earphone device shown in fig. 1, as shown in fig. 10. The earphone box 20 in the above-mentioned application embodiment may not be provided with the rotating member 1010 and the first driving mechanism 1110, alternatively, the earphone box 20 may be provided with the moving member 1020 and the second driving mechanism 1120, the moving member 1020 may be disposed on the box body 100 and movably connected to the box body 100, the first sound receiver 900 is disposed on the moving member 1020, and the second driving mechanism 1120 may be configured to drive the moving member 1020 to rotate, so as to change the position of the first sound receiver 900 on the box body 100. For example, the case 100 may be provided with a sliding groove, the sliding groove may be enclosed around the receiving groove 120, the moving member 1020 may be movably connected with the sliding groove, and the second driving mechanism 1120 may drive the moving member 1020 to move in the sliding groove, so as to change the position of the moving member 1020 in the sliding groove, and further change the position of the first sound receiver 900 on the case 100, so that the first sound receiver 900 corresponds to the sound emitting end 431 of the wireless headset 40.

The second driving mechanism 1120 is electrically connected to the first processor 300, and the first processor 300 is further configured to control the second driving mechanism 1120 to drive the moving member 1020 to move so that the first sound receiver 900 corresponds to the sound emitting end 431 of the wireless earphone 40 when the wireless earphone 40 is accommodated in the accommodating groove 120 and the first sound receiver 900 does not receive the predetermined sound signal.

For example, when the wireless earphone 40 is accommodated in the accommodating slot 120 and the first sound receiver 900 does not receive the preset sound signal, an instruction that the preset sound signal is not received may be sent to the first processor 300, after the first processor 300 receives the instruction sent by the first sound receiver 900, the second driving mechanism 1120 is controlled to drive the moving member 1020 to move, so that the position of the first sound receiver 900 is changed, the first sound receiver 900 searches for the preset sound signal in real time during the position change, when the first sound receiver 900 receives the preset sound signal, the instruction that the preset sound signal is received is started to the first processor 300, and after the first processor 300 receives the instruction that the preset sound signal is received, the second driving mechanism 1120 is controlled to stop working, so that the moving member 1020 stops moving.

As shown in fig. 1, 3 and 4, the wireless headset 40 may further include a second processor such as a second processor 44, and the detection port 41 is electrically connected to the second processor 44, and controls the detection port 41 to output the first voltage signal according to a preset condition. The preset condition may be when the wireless headset 40 is stored in the storage slot 120, when the wireless headset 40 is not worn, when the wireless headset 40 is in a closed state, or when the wireless headset 40 is separated from the storage slot 120. It should be noted that the second processor 44 may also control the detection port 41 to output other voltage signals, such as a second voltage signal or a third voltage signal.

The second processor 44 may be further configured to control the speaker 43 to adjust the intensity of the preset sound signal when the preset sound signal is not received by the first sound receiver 900. For example, when the first sound receiver 900 does not receive the preset sound signal, the first sound receiver 900 transmits the information that the first sound receiver 900 does not receive the preset sound signal to the wireless headset 40 through the communication between the wireless headset 40 and the headset box 20 (for example, the headset box 20 communicates with the wireless headset 40 through the first preset level signal), and the second processor 44 may perform a corresponding operation when receiving the information, for example, increasing the intensity of the preset sound signal emitted by the speaker 43, and increasing the loudness of the preset sound signal.

The wireless earphone 40 is worn in the ear of the user, and if the detection port 41 of the wireless earphone 40 is electrified, the user may touch the electrified detection port 41 in the using process, so that the user is electrically stimulated, and the using experience of the user is further influenced.

With continued reference to fig. 4, the wireless headset 40 may further include a wear detector such as a wear detector 45, and the wear detector 45 may be used to detect whether the wireless headset 40 is in a worn state, which refers to a state in which the wireless headset 40 is worn in the ear of the user. The wear detector 45 may be a capacitive detector or a light-sensitive detector (such as a proximity sensor).

The wearing detector 45 is electrically connected to the second processor 44 to obtain the detection information of the wearing detector 45, and the second processor 44 is configured to control the detection port 41 to output a voltage signal (such as a first voltage signal, a second voltage signal, or a third voltage signal) according to a preset condition when the wireless headset 40 is in an unworn state or an unworn state, where the preset condition refers to any one of the above conditions.

For example, when the user wears the wireless headset 40 on the ear, and the wearing detector 45 detects that the wireless headset 40 is in the wearing state, the first detection instruction is sent to the second processor 44, the first detection instruction is an instruction that the wireless headset 40 is in the wearing state, and after receiving the first detection instruction, the second processor 44 controls the detection port 41 not to output any voltage signal; when the user does not wear the wireless headset 40 on the ear, the wearing detector 45 detects that the wireless headset is not in a wearing state, and sends a second detection instruction to the second processor 44, where the second detection instruction is an instruction that the wireless headset is not in the wearing state, and after the second processor 44 receives the second detection instruction, the detection port 41 is controlled to send out the first voltage signal under a preset condition.

The second processor 44 is also configured to control the speaker 43 to emit a preset sound signal when the wireless headset 40 is not in a wearing state. For example, when the user wears the wireless headset 40 on the ear, and the wearing detector 45 detects that the wireless headset 40 is in the wearing state, a first detection instruction is sent to the second processor 44, where the first detection instruction is an instruction that the wireless headset 40 is in the wearing state, and after receiving the first detection instruction, the second processor 44 controls the speaker 43 not to emit the preset sound signal; when the user does not wear the wireless headset 40 on the ear, the wearing detector 45 detects that the wireless headset is not in a wearing state, and sends a second detection instruction to the second processor 44, where the second detection instruction is an instruction that the wireless headset is not in the wearing state, and after the second processor 44 receives the second detection instruction, the speaker 43 is controlled to emit a preset sound signal when the detection circuit 200 does not detect the first voltage signal.

As shown in fig. 4, the wireless headset 40 is further provided with a second sound receiver such as a second sound receiver 46, the second sound receiver 46 can be used for receiving sound signals emitted by a user, for example, the second sound receiver 46 can be a microphone, the user can record or talk with other users through the second sound receiver 46, and the like.

As shown in fig. 4 and 8, the wireless headset 40 is further provided with a second control circuit such as a second control circuit 47, one end of a second switch 49 is connected to the detection port 41, and the other end of the second switch 49 can switch the connection among the battery 42, the second processor 44, and the second control circuit 47. In the initial state, the other end of the second switch 49 is connected to the second processor 44. Second control circuit 47 may be connected to detection port 41 through second switch 49, and is configured to control detection port 41 to output a second preset level signal, where the second preset level signal is used to establish communication with earphone box 20. For example, the earphone box 20 transmits a first preset level signal to the second processor 44 through the detection port 41, and the second processor 44 responds to the first preset level signal after receiving the first preset level signal, and the response may be performed by transmitting a second preset level signal to the first processor 300 through the detection circuit 200, so as to inform the earphone box 20 of the condition of the wireless earphone 40. In the embodiment of the present application, communication between the earphone box 20 and the wireless earphone 40 is established by transmitting the first preset level signal and the second preset level signal. The second preset level signal may be a level change signal within a preset time period. It should be noted that the second predetermined level signal may also be transmitted to the earphone box 20 by the wireless earphone 40 alone, and does not need to be transmitted after the second processor 44 receives the first predetermined level signal. For example, wireless headset 40 may communicate whether headset 20 is charged, worn, connected to an external device, etc. by transmitting a second preset level signal.

In other embodiments, the voltage signal output by the detection port 41 may not be provided by the battery 42. For example, a dc power source, such as a 5V dc voltage source, may be additionally provided, and the other end of the second switch 49 connects the dc voltage source with the detection port 41, and the dc voltage source provides an electrical signal for the detection port 41, so that the detection port 41 outputs a corresponding voltage signal (e.g., the first voltage signal or the second voltage signal).

Fig. 11 is a communication application scene diagram of the earphone box, the wireless earphone and the mobile terminal according to the embodiment of the present application, which is shown in fig. 4 and 11. The wireless headset 40 is also provided with a wireless communication module, such as wireless communication module 48, and the wireless communication module 48 may be used to communicate wirelessly with other devices, such as the wireless headset 40 may communicate with a mobile terminal, such as mobile terminal 60, through the wireless communication module 48. The wireless communication module 48 may be a bluetooth module, a wireless fidelity communication module, or the like. The mobile terminal 60 may be an electronic device such as a smart phone, a tablet computer, a Personal Digital Assistant (PDA), and the like.

Wireless headset 40 may communicate wirelessly with mobile terminal 60 via wireless communication module 48, wherein wireless communication operations of wireless headset 40 may be initiated by headset case 20, and headset case 20 may indicate whether wireless headset 40 is connected to mobile terminal 60 according to the status of wireless headset 40. For example, in a case that the first control circuit 700 of the earphone box 20 is connected to the detection port 41, when the wireless earphone 40 is taken out of the earphone box 20, the earphone box 20 may send a first preset level signal to the second processor 44, where the first preset level signal carries an instruction indicating that the wireless earphone 40 establishes a communication connection with the mobile terminal 60, and after receiving the instruction, the second processor 44 controls the wireless communication module 48 to be in an operating state and initiate a wireless pairing with the mobile terminal 60, and after receiving the wireless pairing, the mobile terminal 60 may establish a wireless communication connection with the wireless earphone 40, so as to implement a wireless communication between the mobile terminal 60 and the wireless earphone 40, and further implement a function of answering a call or listening to music of the mobile terminal 60 through the wireless earphone 40. When the wireless headset 40 is installed in the headset case 20, the headset case 20 may send a third preset level signal to the second processor 44, where the third preset level signal carries an instruction for instructing to disconnect the communication connection between the wireless headset 40 and the mobile terminal 60, and after receiving the instruction, the second processor 44 controls the wireless communication module 48 to be in a closed state to disconnect the wireless headset 40 and the mobile terminal 60, so as to save power consumption of the wireless headset 40.

In other embodiments, alternatively, the connection state between the mobile terminal 60 and the wireless headset 40 may also be operated by the mobile terminal 60. For example, the mobile terminal 60 may include a third processor that may be used to operate on the wireless connection state of the mobile terminal 60. For example, in the case that the mobile terminal 60 establishes a communication connection with the wireless communication module 48 of the wireless headset 40, when the wireless headset 40 is loaded into the headset case 20, the wireless headset 40 may send an instruction that the wireless headset 40 is loaded into the case to the third processor, and after the third processor receives the instruction that the wireless headset 40 is loaded into the case, the third processor controls the mobile terminal 60 to disconnect from the wireless headset 40, such as directly disconnecting the mobile terminal 60 from the wireless headset 40 or directly turning off a wireless connection switch (e.g., a bluetooth switch) of the mobile terminal 60. When the wireless headset 40 is taken out from the headset case 20, the wireless headset 40 may send an instruction that the wireless headset 40 is taken out of the case to the third processor, and after the third processor receives the instruction that the wireless headset 40 is taken out of the case, the third processor controls the mobile terminal 60 to establish a connection with the wireless headset 40, such as establishing a bluetooth communication connection.

As shown in fig. 12, fig. 12 is a schematic flowchart of a charging method of a wireless headset according to an embodiment of the present application. The embodiment of the present application further provides a charging method for a wireless headset, where the charging method for a wireless headset is applied to a headset case 20 shown in any one of fig. 1 to 11, and the structure of the headset case 20 is as described above, and is not described herein again. The charging method of the wireless earphone comprises the following steps:

101, determining whether the detection circuit detects the first voltage signal, wherein the structure of the wireless headset is shown in fig. 1 and 4, which is not described herein again.

For example, when the user puts the wireless headset 40 into the headset case 20, the detection port 41 of the wireless headset 40 outputs a first voltage signal, and when the detection circuit 200 in the headset case 20 detects the first voltage signal, a detection result of "the first voltage signal has been detected" may be transmitted to the first processor 300. The first processor 300 may determine whether the detection circuit detects the first voltage signal output by the wireless headset 40 according to whether the detection result of "the first voltage signal has been detected" is received.

102, if the detection circuit detects the first voltage signal, determining that the wireless headset is accommodated in the accommodating slot.

For example, the first processor 300 acquires the detection result of the detection circuit 200, and determines that the wireless headset 40 has been received in the receiving slot 120 if the detection result of the detection circuit 200 is "the first voltage signal has been detected". If the detection result of the detection circuit 200 is "the first voltage signal is not detected", there may be various cases. For example, the wireless earphone 40 is not placed in the receiving slot 120, or the wireless earphone 40 is not placed in a preset position of the receiving slot 120, for example, the left earphone is placed in the second receiving slot or the detection port 41 of the wireless earphone 40 is not placed corresponding to the detection circuit 200, so that the detection circuit 200 does not detect the first voltage signal, and possibly the detection circuit 200 is damaged so as not to detect the first voltage signal. The above is merely an example of the case where the detection circuit 200 does not detect the presence of the first voltage signal, and is not to be construed as a limitation of the possible case where the detection circuit 200 does not detect the presence of the first voltage signal.

103, controlling the other end of the first switch to be connected with the power supply, and controlling the power supply to charge the wireless headset.

For example, when the first processor 300 determines that the wireless headset 40 is accommodated in the accommodating slot, the other end of the first switch 500 is controlled to be disconnected from the first processor 300, the other end of the first switch 500 is electrically connected to the power supply 400, and the power supply 400 is controlled to charge the wireless headset 40.

In some embodiments, after controlling the other end of the first switch to be connected to the power supply and controlling the power supply to charge the wireless headset at 103, the method may further include:

acquiring the second voltage signal;

and adjusting the rate of charging the wireless earphone by the power supply according to the magnitude of the second voltage signal.

For example, the detection circuit 200 may obtain the state of charge of the battery 42 through the detection port 41, and the state of charge may be a current charge value or a to-be-charged value. After detecting the second voltage signal, the detection circuit 200 sends the detected second voltage signal to the first processor 300, and after receiving the second voltage signal, the first processor 300 determines whether the charging rate needs to be adjusted according to the second voltage signal. For example, a threshold may be preset, and when the second voltage signal is less than or equal to the threshold, the first processor 300 may increase the charging rate of the power supply 400; when the second voltage signal is greater than the threshold, the first processor 300 may decrease the charge rate of the power supply 400, or not operate, or maintain the current charge rate, etc.

The earphone box, the earphone device, the mobile terminal and the charging method of the wireless earphone provided by the embodiment of the application are described in detail above. The principles and implementations of the present application are described herein using specific examples, which are presented only to aid in understanding the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
