Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a low power consumption method of a wireless headset according to an embodiment of the present invention. The method can comprise the following steps:
step 101: after the wireless earphone is started, acquiring a detection signal output by a preset sensor; wherein the preset sensor is arranged in the wireless earphone.
It should be noted that the preset sensor in this step may be a sensor arranged in the wireless headset and used for detecting a scene of entering and exiting the charging box of the wireless headset. The purpose of this step may be that a processor (such as a bluetooth chip) in the wireless headset obtains a detection signal output by the preset sensor when the wireless headset is in a powered-on state, so as to determine an in-out charging box scene of the wireless headset by using the detection signal in the following.
Specifically, the specific type of the preset sensor and the specific setting position in the wireless headset can be set by a designer according to a practical scene and user requirements, for example, the hall sensor shown in fig. 2 can be used for the preset sensor, that is, a magnet (e.g., a magnet) can be correspondingly arranged in the charging box, so that a processor (e.g., a bluetooth chip) in the wireless headset can determine the distance between the hall sensor and the magnet, that is, the distance between the wireless headset and the charging box, according to a detection signal output by the hall sensor, thereby determining whether the wireless headset is in the charging box; the preset sensor can also be a distance sensor (such as an infrared distance measuring sensor, an ultrasonic distance measuring sensor, a laser distance measuring sensor and the like), so that the processor in the wireless earphone can determine the distance between the wireless earphone and the position detected by the distance sensor according to a detection signal output by the distance sensor, and further determine whether the wireless earphone is in the charging box. The embodiment is not limited in any way as long as the processor in the wireless headset can determine whether the wireless headset is in the charging box according to the detection signal output by the preset sensor.
Correspondingly, the specific type of the detection signal in this step may be set by a designer according to the specific type of the preset sensor, for example, when the preset sensor is a switch-type hall sensor, the detection signal may be a level signal including a high level signal and a low level signal; when the preset sensor is a distance sensor or a linear hall sensor, the detection signal may be an analog level signal.
Step 102: judging whether the wireless earphone is in the charging box or not according to the detection signal; if yes, go to step 103.
It is understood that the purpose of this step may be to utilize the detection signal output by the preset sensor by the processor in the wireless headset to determine whether the wireless headset is in the charging box, i.e. the wireless headset goes in and out of the charging box scene.
Specifically, the specific manner in which the processor in the wireless headset judges whether the wireless headset is in the charging box according to the detection signal in the step can be set by a designer according to a practical scene and user requirements, for example, the detected distance value can be determined according to the detection signal output by a preset sensor, and whether the wireless headset is in the charging box is determined by comparing the distance value with a preset distance value range of the wireless headset in the charging box; for example, when the preset sensor is a distance sensor, the processor may determine the distance value detected by the distance sensor according to the detection signal acquired by the distance sensor, so that when the distance values detected within a certain time period are all within the range of the preset distance value, the wireless headset is determined to be in the charging box; the preset distance value range can correspond to the position of the distance sensor in the wireless earphone and the structure of the wireless earphone and the charging box, and the preset distance value range can be a range which is larger than the contact threshold and smaller than the box entering threshold, so that the influence on box entering detection when a user contacts the handheld wireless earphone is avoided through the setting of the contact threshold. . Or, directly determine whether the wireless headset is in the charging box according to a detection signal output by a preset sensor, for example, when the preset sensor is a hall sensor of a switch type, the hall sensor may output a low level signal when detecting that the magnetic field strength is greater than a preset value, that is, when the hall sensor is a preset distance from a magnet in the charging box, that is, when detecting a low level, a processor in the wireless headset may determine that the wireless headset is in the charging box. The present embodiment does not limit this as long as the processor in the wireless headset determines whether the wireless headset is in the charging box according to the received detection signal.
Correspondingly, for the case that it is determined in this step that the wireless headset is not in the charging box, the processor may control the wireless headset in a manner the same as or similar to a normal wireless headset control method in the prior art, which is not limited in this embodiment.
Step 103: judging whether the wireless earphone is in a low-power-consumption starting scene or not according to the electric quantity information of the wireless earphone and/or the charging box; if yes, go to step 104.
The low power consumption start scene in this step may be a use scene in which the wireless headset in the charging box needs to enter the low power consumption mode, that is, an entry condition of the low power consumption mode. The low-power-consumption starting scene can be of a specific type and can be set by a designer, for example, the low-power-consumption starting scene can comprise a charging box power-off scene which cannot charge the wireless earphone; the low power consumption startup scenario may further include that the power of the wireless headset in the charging box reaches a preset power, and a wireless headset full charge scenario in which the charging box is not required to be charged, for example, a wireless headset full charge scenario in which the wireless headset is fully charged. The present embodiment does not set any limit to this.
It is understood that the purpose of this step may be to determine whether the wireless headset is in a low power consumption startup scenario, i.e. whether the wireless headset needs to go to a low power consumption mode, by the processor in the charging box through the power information of the wireless headset and/or the power information of the charging box. Specifically, in this step, the specific manner of determining whether the wireless headset is in the low-power-consumption startup scenario or not according to the power information of the wireless headset and/or the charging box may be set by a designer according to the setting of the low-power-consumption startup scenario, and if the low-power-consumption startup scenario only includes the charging box no-power scenario, the processor may determine whether the wireless headset is in the charging box no-power scenario or not according to the received power information (e.g., charging output voltage) of the charging box, that is, whether the charging box is powered off or not, so that when the wireless headset is in the charging box no-power scenario, the wireless headset enters the low-power-consumption mode through step 104, and the standby time of. The low power consumption starting scene comprises a charging box power-free scene and a wireless earphone power-free scene, and the processor can respectively or sequentially judge whether the wireless earphone power-free scene and the wireless earphone power-free scene are in the charging box power-free scene or not according to the power information of the charging box and the wireless earphone, so that when the wireless earphone power-free scene or the charging box power-free scene is in, the wireless earphone power-free scene enters a low power consumption mode through step 104, and the time that a user can use the wireless earphone is prolonged.
Specifically, the electric quantity information of the wireless headset in this step may be information corresponding to the battery electric quantity of the wireless headset that can be acquired by the processor in the wireless headset, and the electric quantity information of the charging box may be information corresponding to the battery electric quantity of the wireless headset that can be acquired by the processor in the wireless headset. The specific content and the obtaining mode of the electric quantity information of the wireless earphone and the charging box can be set by a designer, and because the processor in the wireless earphone only needs to determine whether the charging box is charged or not, the electric quantity information of the charging box can be the voltage on a charging pin connected with the charging box, namely the charging output voltage of the charging box; that is, the processor may determine whether the charging cartridge is charged directly from the charging output voltage of the charging cartridge.
It should be noted that in this step, after the processor determines that the wireless headset is placed in the charging box, it is determined whether the wireless headset needs to enter the low power consumption mode. That is, the processor may also perform corresponding operations after determining that the wireless headset is placed in the charging box in the prior art before or during the step, which is not limited in this embodiment.
Correspondingly, for the case that it is determined in this step that the wireless headset is not in the low-power-consumption start-up scene, the processor may control the wireless headset in the same or similar manner as the normal wireless headset control method in the prior art, which is not limited in this embodiment.
Step 104: entering a low power consumption mode; wherein, the wireless earphone only supports the low-power wake-up function in the low-power mode.
It is understood that the low power mode in this embodiment is different from the conventional low power mode, and can be a state where the whole chip (e.g. bluetooth chip) of the processor enters a stall state. In this state, all GPIO (general purpose input/output) pins cannot be output or charged, and any other functions cannot be used, and only the low power wake-up function is supported, that is, a specific GPIO pin wakes up the chip in a specific manner (for example, a rising edge or a falling edge). That is, the low power mode entered by the wireless headset may correspond to a power-off state that supports soft reset by the low power wake-up function. In this embodiment, the wireless headset in the low power consumption startup scenario in the charging box is enabled to enter the low power consumption mode, so that the power consumption of the wireless headset can be reduced, and the time that the wireless headset can be used by a user is prolonged.
Correspondingly, the method provided by the embodiment may further include a wake-up process after the wireless headset enters the low power consumption mode, and the specific setting of the wake-up process may be set by a designer, for example, the processor may reset the wireless headset to power on only when the wireless headset leaves the charging box, so as to wake up the wireless headset; that is, the processor can judge whether the wireless headset is in a wireless headset out-of-box scene only according to the detection signal output by the preset sensor, that is, whether the wireless headset is taken out of the charging box. When the low-power-consumption starting scene only comprises a charging box non-electricity scene, the processor can reset the wireless earphone and wake up the wireless earphone when the charging box is charged again and the wireless earphone leaves the charging box, namely, the processor can judge whether the wireless earphone is in a wireless earphone outgoing scene or a charging box electricity scene according to the detection signal output by the preset sensor and the electric quantity information of the charging box. When the low-power-consumption starting scene comprises a plurality of using scenes, the processor can reset and start the wireless earphone when being in a low-power-consumption awakening scene corresponding to the target low-power-consumption starting scene, and awaken the wireless earphone; the target low-power-consumption starting scene can be a low-power-consumption starting scene when the wireless earphone enters a low-power-consumption mode, and if the target low-power-consumption starting scene is a charging box non-electricity scene, the corresponding low-power-consumption awakening scene can be a wireless earphone outgoing scene and a charging box electricity scene; when the target low-power-consumption starting scene is a charging box electroless scene, the corresponding low-power-consumption awakening scene can be a wireless earphone outgoing box scene and a wireless earphone insufficient electric quantity scene, namely the electric quantity of the wireless earphone is lower than the electric quantity lower limit scene, and the electric quantity lower limit is smaller than or equal to the preset electric quantity.
In the embodiment of the invention, the scene that the wireless earphone enters and exits the charging box is detected by using the preset sensor by judging whether the wireless earphone is in the charging box according to the detection signal, so that the use scene that the wireless earphone enters the charging box can be detected when the charging box is not charged, and the detection accuracy of the scene that the wireless earphone enters and exits the charging box is ensured; through the setting of low-power consumption mode, the power consumption of the wireless earphone entering the low-power consumption mode in the charging box is reduced, the electric quantity of the wireless earphone and the charging box is reserved to a greater extent, and the service time of a user is prolonged.
Referring to fig. 3, fig. 3 is a flowchart illustrating a low power consumption method of a wireless headset according to another embodiment of the present invention. The method can comprise the following steps:
step 201: and after the wireless earphone is started, acquiring a level signal output by the Hall sensor.
It is understood that the processor in the wireless headset in the present embodiment determines whether the wireless headset is in the charging box using a level signal (detection signal) output from a hall sensor provided in the wireless headset. Correspondingly, in the present embodiment, a magnet (such as the magnet in fig. 2) may be disposed in the charging box, so that the hall sensor may better detect the magnetic field strength corresponding to the charging box, i.e., the distance between the charging box and the hall sensor.
Specifically, the level signal output by the hall sensor in this embodiment may include a high level signal and a low level signal, that is, the hall sensor in this embodiment may be a switch-type hall sensor. As shown in fig. 2, three pins, namely a +1V8 pin, a GND pin and an INT pin, may be connected between the bluetooth chip (processor) and the hall sensor in the wireless headset. The +1V8 pin and the GND pin are used for supplying power to the Hall sensor, and the INT pin is used for receiving a level signal sent by the Hall sensor. When the Hall sensor detects that the distance between the Hall sensor and the magnet is reduced to a preset distance, namely the magnetic field intensity is detected to be greater than a certain intensity, the Hall sensor outputs a low-level signal through the INT pin to inform the Bluetooth chip that the wireless earphone is plugged into the box at the moment; when the Hall sensor detects that the distance between the Hall sensor and the magnet is increased to the upper limit value of the distance, namely the magnetic field intensity is detected to be less than a certain intensity, the Hall sensor outputs a high-level signal through the INT pin to inform the Bluetooth chip that the wireless earphone is taken out of the box at the moment.
Step 202: judging whether a low level signal output by the Hall sensor is received or not; if yes, go to step 203.
In the present embodiment, the level signal output by the hall sensor when detecting that the distance from the magnet in the charging box is less than the preset distance is a low level signal. That is to say, the present embodiment is exemplified by a low level output by the hall sensor when the distance between the hall sensor and the magnet in the charging box is smaller than the preset distance, and for a case that the hall sensor can also output a high level signal when the distance between the hall sensor and the magnet in the charging box is smaller than the preset distance, the method provided by the present embodiment can be adopted for setting, and the present embodiment does not limit the present embodiment.
It will be appreciated that the purpose of this step is to determine whether the wireless headset is placed in the charging box based on the low level signal output by the hall sensor. For the specific manner of determining whether the wireless headset is placed in the charging box in this step, after receiving the low level signal output by the hall sensor, directly determining that the wireless headset is placed in the charging box, and proceeding to step 203; or after continuously receiving the low level signal output by the hall sensor for a certain time, determining that the wireless headset is placed in the charging box, that is, the step may be to determine whether the low level signal output by the hall sensor is continuously received within a preset time period, and if so, entering step 203. The present embodiment does not set any limit to this.
Step 203: judging whether the charging box is electroless or not according to the charging output voltage of the charging box; if not, go to step 204; if yes, go to step 205.
It is understood that the purpose of this step may be to determine whether the charging box is dead, i.e. to determine whether the wireless headset is in a charging box dead scenario, based on the charging output voltage of the charging box, i.e. the voltage on the charging pin connected to the charging box (e.g. pin +5V in fig. 2); thus, when the charging box is not powered, the low power consumption mode is entered, via step 205.
Step 204: judging whether the electric quantity of the wireless earphone reaches a preset electric quantity or not; if yes, go to step 205.
It can be understood that the purpose of this step may be that the processor in the wireless headset determines whether the wireless headset is in a wireless headset full power scene by judging whether the power of the wireless headset reaches a preset power; thus, when the wireless headset currently has sufficient power, the wireless headset is not charged any more, and enters the low power consumption mode through step 205.
Specifically, the specific value setting of the preset electric quantity in this step may be set by a designer, and if the preset electric quantity is full (i.e. 100%), that is, when the wireless headset in the charging box is in a full electric field scene of the fully charged wireless headset, the wireless headset may enter a low power consumption mode; other values of the electric quantity, such as 90%, may be used, which is not limited in this embodiment.
Correspondingly, the processor in the wireless headset in the step can judge whether the electric quantity of the wireless headset reaches the preset electric quantity according to the electric quantity information of the wireless headset. The specific obtaining mode of the power information of the wireless headset may be set by a designer, for example, the power information may be implemented in a manner the same as or similar to the battery power obtaining method in the prior art, for example, the power of the battery is determined according to the output voltage of the battery, and this embodiment does not limit this.
It should be noted that there is no necessary logical order between this step and step 204, and this step may be performed first in step 204 and then in the case where it is determined that the charging box is powered; alternatively, the step 204 may be performed first, and then the wireless headset may be performed when the power of the wireless headset is less than the preset power. The present embodiment does not set any limit to this.
Step 205: entering a low power consumption mode; wherein, the wireless earphone only supports the low-power wake-up function in the low-power mode.
It can be understood that the low power consumption mode in this embodiment is entered after the wireless headset is charged to a preset amount of electricity (e.g., fully charged) in the charging box in the power-on state or after the wireless headset is entered in the charging box in the power-off state. Because the wireless earphone enters a low power consumption mode, the whole chip of the processor enters a dead state, all GPIO (general purpose input/output) pins cannot be output and charged, any other functions cannot be used, and only the low power consumption awakening function is supported, so that the power consumption of the wireless earphone can be only 0.12ma, while the power consumption of the existing wireless earphone in the existing standby mode is 8ma, namely the standby time in the box is prolonged by 66 times in the full power state of the wireless earphone.
Specifically, when the wireless headset enters the box (enters the charging box), the charging box has two situations of no power supply and power supply, and each situation is divided into two scenes. When the charging box is not powered, the wireless earphone is put into the box, and the charging box is powered on after the wireless earphone is put into the box for a period of time; when the charging box is charged, the earphone entering box is divided into two scenes of charging the wireless earphone to full power (preset electric quantity) and suddenly not charging the charging box in the charging process. As shown in fig. 4, the wireless headset may determine that the wireless headset is inside the charging box according to the in-box interrupt (e.g., low level signal) of the hall sensor; the wireless earphone can enter a low power consumption mode by judging whether the charging box is in a non-power state or not under the two conditions that the charging box is in a non-power state all the time after the wireless earphone is placed in the charging box and the charging box is in a non-power state suddenly in the charging process; and when the wireless earphone is charged to full power, whether the electric quantity of the wireless earphone reaches the preset electric quantity or not can be judged by determining, and the wireless earphone enters a low power consumption mode. Correspondingly, as shown in fig. 4, when the processor of the wireless headset receives an interrupt (such as a high level signal, i.e., a rising edge) output by the hall sensor, it may determine that the wireless headset goes out of the box (takes out the charging box), so that the wireless headset is reset and turned on; when the processor receives a power-on signal of the charging box, the charging box can be determined to be powered on after being put into the charging box for a period of time, so that the wireless earphone is reset and started; the processor can also enable the wireless earphone to be reset and started up when receiving the power-down signal of the charging box, if the charging box is powered on, the preset power-down signal can be output according to the preset time interval, so that the wireless earphone can replenish consumed electric quantity again after entering the low power consumption mode due to full electric quantity, the wireless earphone does not need to detect the electric quantity information of the wireless earphone, and the consumption of the wireless earphone in the low power consumption mode is further saved.
