Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It is understandable that the specific embodiments described here are only used to explain the related application, but not to limit the application. In addition, it should be noted that, for ease of description, only the parts related to the relevant application are shown in the drawings.

With the continuous advancement of terminal technology, headsets are constantly changing. Among them, the TWS headset, which is based on TWS technology, applies TWS technology to the field of Bluetooth wireless headsets. The left and right earplugs of such wireless earphones such as TWS earphones do not need to be connected by a cable, and can work independently only by realizing the wireless separation of the left and right channels.

Wireless earphones such as TWS earphones can completely get rid of the trouble of being bound by cables and have more freedom of movement. At the same time, wireless earphones can be used in a variety of ways, which can be exclusive, shared, and one device can be used as two devices.

For wireless earphones, there can be a matching earphone box. The function of the earphone box is to store the wireless earphones. Correspondingly, the earphone box is also integrated with a mobile power supply. Therefore, when the TWS earphone is out of power, just put it in the earphone box. Can be charged.

It is understandable that there is generally at least one metal pin at the bottom of the wireless earphone, called POGO PIN. When the wireless earphone is placed in the earphone box, the POGO PIN can make the circuit between the wireless earphone and the earphone box conduct, thereby Charge the wireless headset. Common wireless earphones are set with 2 PINs or 3 PINs, which are generally located at the corresponding positions on the wireless earphone and earphone box. When the wireless earphone is placed in the earphone box, the POGO PIN on the earphone and the POGO PIN on the earphone box will be Just touching and conducting.

Under normal circumstances, when wireless headsets are in use, it is often necessary to determine the switch state of the headset box first, so that it can be further confirmed whether to automatically turn on or turn off Bluetooth and other functions. Specifically, the wireless earphone can determine the on-off state of the earphone box through the setting of the Hall sensor.

When a piece of metal or semiconductor sheet with current is placed vertically in a magnetic field, a potential difference will be generated at both ends of the sheet. This phenomenon is called the Hall effect. The sensitivity of the Hall effect is proportional to the magnetic induction intensity of the applied magnetic field. Hall switch belongs to this kind of active magnetoelectric conversion device. It is made by integrated packaging and assembly process based on the principle of Hall effect, which can easily convert magnetic input signals into electrical signals in practical applications. At the same time, it also meets the requirements of easy operation and reliability in practical industrial applications.

Figure 1 is a schematic diagram of a wireless headset and a headset box. As shown in Figure 1, at present, the wireless headset can be provided with a Hall sensor A. Accordingly, a magnet B is placed on the top of the headset box. The output level of the earphone sensor changes, and the wireless earphone can judge the switch state of the earphone box by detecting the level change of the Hall sensor output. Specifically, when the box cover of the earphone box is opened, the Hall sensor outputs a high level, and when the box cover of the earphone box is closed, the Hall sensor outputs a low level. When the interrupt is triggered, the wireless earphone can determine the on-off state of the earphone box by monitoring the corresponding voltage.

However, the existing wireless earphones method for detecting the on-off state of the earphone box has the following defects:

1. The wireless earphone requires additional components. For example, when a Hall sensor is used for detection, a Hall sensor needs to be added, and the left and right earphones need a Hall sensor each, so the cost is higher.

2. The occupied space is relatively large. It is precisely because of the need to add Hall sensors and other devices in the wireless headset, it will increase the size of the wireless headset, and at the same time will affect the shape and structure of the wireless headset, and reduce the user experience.

3. Reliability is unstable. For example, the function of the magnet induced by the Hall sensor will fail at high temperature and after a period of use. This will cause the detection of the switch state to be wrong, reduce the accuracy of the detection, and have poor reliability.

In other words, the existing switching detection method of adding a Hall sensor to a wireless headset will affect the shape and structure of the wireless headset, and the Hall sensor will fail to function at high temperatures, which will directly cause detection errors. , Which reduces the accuracy of detection, leading to the defect of poor reliability of wireless headsets.

In order to solve the problems existing in the prior art, in the embodiments of the present application, the wireless earphone can directly perform the switch detection of the earphone box by using the sound generating device and the sound receiving device configured by itself, without adding additional devices such as a Hall sensor. On the one hand, it significantly reduces the production cost of wireless earphones. On the other hand, it greatly reduces the size and structural complexity of wireless earphones. On the other hand, it avoids the risk of magnet failure after a period of use, and effectively improves the reliability of wireless earphones. .

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

An embodiment of the present application provides a switch detection method, which is applied to a wireless headset. Specifically, FIG. 2 is a schematic diagram of the composition structure of a wireless headset. As shown in FIG. 2, in the embodiment of the present application, The wireless headset 10 may include a sound emitting module 11, a sound receiving module 12, and a power supply module 13.

It should be noted that, in the embodiment of the present application, the wireless headset 10 may be a TWS headset based on TWS technology.

It can be understood that, in the embodiment of the present application, the sound emitting module 11 configured in the wireless earphone 10 is mainly a module for emitting sound signals, such as a sound emitting device such as a speaker. Among them, the loudspeaker, also known as the "horn", is a very commonly used electroacoustic transducer. The loudspeaker is a transducer that converts an electric signal into an acoustic signal. The performance of the loudspeaker has a great influence on the sound quality. The speaker is one of the weakest components in audio equipment, and it is the most important component for audio effects. There are many types of speakers, and the prices vary greatly. Audio electric energy uses electromagnetic, piezoelectric or electrostatic effects to make the cone or diaphragm vibrate and resonate (resonate) with the surrounding air to produce sound.

It can be understood that, in the embodiment of the present application, the sound receiving module 12 configured in the wireless earphone 10 is mainly a module for receiving sound signals, such as a sound transmission device such as a microphone. Among them, the microphone (microphone), the scientific name is microphone, also known as microphone, microphone. A microphone is an energy conversion device that converts sound signals into electrical signals. Specifically, it can be divided into moving coil type, capacitive type, electret, and the recently emerging silicon micro-microphone, in addition to liquid microphones and laser microphones. Most microphones are electret condenser microphones, and their working principle is to use a polymer material diaphragm with permanent charge isolation.

It can be understood that, in the embodiment of the present application, the power module 13 configured in the wireless headset 10 may specifically include a power supply circuit, and further, may also include a charging circuit.

FIG. 3 is a second schematic diagram of the structure of the wireless headset. As shown in FIG. 3, in the embodiment of the present application, the wireless headset 10 may also be provided with a POGO PIN14. Among them, POGO PIN is a precision connector used in mobile phones and other electronic products, and is widely used in semiconductor equipment to play a connection role. Specifically, POGO PIN is a spring-type probe formed by the three basic components of a needle shaft, a spring, and a needle tube after being riveted and pre-compressed by a precision instrument. There is a precision spring structure inside. The surface coating of POGO PIN is generally gold-plated, which can better improve its anti-corrosion function, mechanical properties, and electrical properties. The needle tip has sharp needles, grasping needles, round needles, knife-shaped needles and so on. POGO PIN is generally used for precision connections in electronic products such as mobile phones, communications, automobiles, medical, aerospace, etc., which can improve the corrosion resistance, stability, and durability of these connectors. Since POGO PIN is a very fine probe, it can be used in precision connectors to reduce the weight and appearance of the connector, which can make the connector more refined and beautiful.

It is understandable that, in the embodiment of the present application, the POGO PIN14 in the wireless headset 10 may be a metal pin, which is generally arranged at the bottom of the two earphones or under the earplugs. Wherein, when the wireless earphone is placed in the earphone box, the POGO PIN 14 can conduct the circuit between the wireless earphone 10 and the earphone box, thereby charging the wireless earphone. Common wireless earphones are set with 2 or 3 POGO PINs, which are located at the corresponding positions on the wireless earphone and earphone box. When the wireless earphone is placed in the earphone box, the POGO PIN on the wireless earphone and the POGO PIN on the earphone box Will just touch and conduct.

It should be noted that, in the embodiments of the present application, the wireless headset performing switch detection refers to detecting whether the cover of the headset box is in an open state or a closed state. Specifically, if the wireless headset is placed in the headset box for charging, once the cover of the headset box is opened, it can be considered that the wireless headset needs to be used. Therefore, the wireless headset needs to broadcast so that the surrounding terminals can recognize the wireless headset. Connect with the terminal, such as Bluetooth connection. Correspondingly, if the wireless headset is put into the headset box after use, once the cover of the headset box is closed, it can be considered that the wireless headset does not need to be used. In order to save power consumption, it is no longer necessary to connect to the terminal, then the wireless headset is disconnected Connection with the terminal.

It can be seen that it can ensure that the wireless headset can accurately perform switch detection, and can establish a connection with the terminal in time when it needs to be used, and it can also disconnect with the terminal in time when it is not needed, thus improving the intelligence of the wireless headset. , And save power consumption.

Fig. 4 is a schematic diagram 1 of the implementation process of the switch detection method. As shown in Fig. 4, the switch detection method of the wireless headset may include the following steps:

Step 101: After the power supply module detects the excitation voltage input from the earphone box, it generates a preset audio signal through the sounding module.

In the embodiment of the present application, after the power module in the wireless earphone detects the excitation voltage input by the earphone box, the wireless earphone can generate the preset audio signal through the sound module.

In a feasible implementation manner, the detection of the excitation voltage input by the earphone box by the power module may include: the wireless earphone receives the charging voltage (for example, a 5V voltage) transmitted by the earphone box. That is to say, the wireless earphone is put into the earphone box for charging. When the wireless earphone receives the charging voltage transmitted by the earphone box, the wireless earphone generates a preset audio signal through the sound module, and collects the audio signal through the sound module to obtain the target The audio signal is used for the wireless headset to determine the open status of the charging box, and then determine the Bluetooth connection status with mobile phones and other terminal devices.

In a feasible implementation manner, the power supply module detecting the excitation voltage input by the earphone box may further include: the first preset voltage transmitted by the earphone box to the earphone when the earphone box is in a dormant state. That is to say, when the earphone box is in a sleep state, the earphone box will still emit a first preset voltage, which may not be enough to enable the earphone box to supply power to the wireless earphone, but can stimulate the sound device of the wireless earphone to emit The audio is preset, and the sound receiver performs audio collection to obtain the target audio signal, so that the wireless headset can determine the open state of the charging box, and then determine the Bluetooth connection state with terminal devices such as mobile phones.

It can be seen that for the above two different excitation voltage transmission methods, the earphone box itself does not need to detect whether the cover is opened or not. The wireless earphones in the earphone box are either in the charging state, receiving the charging voltage, or receiving sleep in the fully charged state. The first preset voltage output by the earphone box in the state, or the earphone box enters the dormant state due to low power, stops supplying power to the wireless earphone but keeps outputting the first preset voltage to the wireless earphone. Therefore, after the wireless earphone is placed in the earphone box, it will continue to detect whether the charging box is open or closed by sending preset audio signals and collecting audio signals. When the wireless earphone is taken out of the earphone box, it no longer receives the excitation voltage, thereby stopping the generation of the preset audio signal and the collection of the audio signal.

In a feasible implementation manner, the power module detecting the excitation voltage input by the earphone box may also include: when the earphone box itself detects opening and closing of the cover, emitting a second preset voltage to excite the sound device of the wireless earphone to emit a preset audio , And the sound receiving device performs audio collection to obtain the target audio signal.

For example, after the wireless earphone is put into the earphone box, the wireless earphone is in contact with the earphone box. When the earphone box detects that the cover is closed, the earphone box sends the second preset voltage to the wireless earphone. The wireless earphone receives the second preset voltage. , The sound module of the wireless earphone generates the preset audio, and the sound module of the wireless earphone collects the audio signal to obtain the target audio. Since the cover of the earphone box is closed, the collection of the preset audio signal is affected, so that it can be judged that the earphone box is closed and the Bluetooth connection is disconnected. When the earphone box is opened, the second preset voltage is sent to the wireless earphone in the earphone box, so that the sound module of the wireless earphone generates the preset audio, and the sound module of the wireless earphone collects audio signals to obtain the target audio. Since the earphone box is opened, the collection of the preset audio signal will not be affected, so it is judged that the earphone box is opened and the Bluetooth is connected back. This implementation manner can also be applied when the earphone box is in a sleep state, when the earphone box is opened or closed, the earphone box transmits the second preset voltage to the earphone. The second preset voltage may be a voltage value different from the charging voltage and the first preset voltage.

It is understandable that, in the above-mentioned embodiment, the earphone box itself needs to have the cover opening detection function, so that the excitation voltage can be sent to the wireless earphone in time when the cover opening and closing is detected, so that after the wireless earphone is placed in the earphone box, its sound device and The sound receiving device does not need to continuously send out and collect preset audio signals, but only send out and collect preset audio signals after the cover of the earphone box is opened and closed, which can reduce the power consumption of wireless earphones. In addition, compared with the prior art , There is no need to add sensors such as infrared and Hall on the earphone, but the speaker and microphone of the wireless earphone can be reused to realize the earphone detection, which can reduce the weight of the wireless earphone.

It should be noted that the above embodiments can be combined without conflict. For example, when the earphone box has the function of detecting the switch cover, the wireless earphone can continuously or intermittently generate the preset audio signal and collect the audio signal in the charging state. In the dormant state, it is necessary to combine the opening and closing detection function of the earphone box. When the earphone box detects that the cover is opened or closed, the excitation voltage is sent out, which triggers the wireless earphone to generate a preset audio signal and collect the audio signal.

It is understandable that, in this application, the earphone box can be changed from the closed state to the open state in the sleep state. Among them, the sleep state of the earphone box may mean that the earphone box stops supplying power to the wireless earphone and enters a low power consumption state. Specifically, the sleep state may include two different situations. One is that the headset box enters the sleep state after the wireless headset is fully charged, and the other is that the headset box no longer supplies power to the wireless headset and enters the sleep state when the headset box has insufficient power.

It should be noted that in some embodiments of the present application, when the earphone box detects that the lid is opened, the wireless earphone can be activated by outputting an excitation voltage. Accordingly, the power module of the wireless earphone can receive the earphone box input The excitation voltage can be a charging voltage or other preset voltages, such as a first preset voltage or a second preset voltage. Specifically, in this application, the earphone box and the wireless earphone are provided with a POGO PIN at the positions corresponding to each other. After the earphone box detects that the cover is opened, it can output the excitation voltage through the POGO PIN on the earphone box. It is recognized by the power module through the corresponding POGO PIN on the wireless headset.

Further, in some embodiments of the present application, after the wireless earphone is put into the earphone box, the POGO PIN in the wireless earphone and the corresponding POGO PIN in the earphone box are in contact with each other, so that the earphone box recognizes the insertion of the wireless earphone , And output the excitation voltage through the POGO PIN, the power module of the headset can further detect the excitation voltage through the POGO PIN.

It is understandable that in some embodiments of the present application, the power module in the wireless headset can activate the sound generating module and the sound receiving module after detecting the excitation voltage input by the earphone box, so that the sound generating module and the sound receiving module can be used. The module determines the switch state of the earphone box.

It should be noted that, in the embodiment of the present application, the wireless headset needs to further determine the connection state with the terminal according to the on or off state of the headset box. Therefore, the wireless headset needs to perform accurate switch detection on the headset box.

It is understandable that, in some embodiments of the present application, the earphone box needs to have a detection function of opening and closing the cover, and the earphone box can determine the open state or the closed state of the box cover in a variety of ways. Specifically, a Hall sensor can be provided in the earphone box, so that the Hall sensor can be used to detect the state change of the box cover. An infrared sensor can also be provided in the earphone box, so that the infrared sensor can be used to detect the state change of the box cover.

Step 102: Perform audio collection through the sound receiving module to obtain a target audio signal; wherein the target audio signal is used to determine the situation in which the sound receiving module obtains a preset audio signal.

In the embodiment of the present application, after the sound generating module in the wireless earphone generates the preset audio signal, the sound receiving module in the wireless earphone may perform audio collection to obtain the target audio signal.

It should be noted that, in the embodiment of the present application, the target audio signal is used to determine the condition that the sound receiving module can receive the preset audio signal.

It is understandable that, in the embodiment of the present application, after the sound module in the wireless earphone generates and sends out the preset audio signal, when the sound receiver module in the wireless earphone performs audio collection, if the earphone box is turned on, then The radio module can collect audio signals. If the earphone box is closed, the cover of the earphone box will block the transmission of audio signals between the sound module and the radio module, which will affect the radio module’s ability to preset audio signals. Collection.

In a feasible implementation manner, when the wireless headset receives the excitation voltage, the sound module will continuously or intermittently emit a preset audio signal, and the sound receiver module will correspondingly continuously or intermittently collect the audio signal. Further, To prevent the user from hearing the preset audio signal, the preset audio signal can be set to a frequency that cannot be heard by human ears.

Further, in some embodiments of the present application, when the wireless earphone generates and emits a preset audio signal through the sound emitting module, it may emit the preset audio signal according to a preset time threshold. Correspondingly, when the wireless earphone collects audio through the sound receiving module, it can also collect audio according to the preset time threshold. Wherein, the preset time threshold may be a time parameter preset and stored by the wireless headset, in order to prevent misidentification. For example, after receiving the excitation voltage, a preset audio signal is generated within a preset time threshold, and the audio signal is collected, thereby increasing the accuracy of detection. In another case, it is also possible to send out a round of preset audio signals and collect audio signals every preset time threshold, thereby reducing power consumption. The preset time threshold can be set according to actual application conditions.

It is understandable that, in some embodiments of the present application, the sound emitting module may continuously emit the preset audio signal according to the preset time threshold, or may intermittently emit the preset audio signal according to the preset time threshold. Correspondingly, the sound receiving module can continuously perform audio collection according to the preset time threshold, or can perform audio collection intermittently according to the preset time threshold, so as to obtain the target audio signal. That is to say, in order to prevent misidentification, the sound generating module and the sound receiving module may continuously or intermittently emit and collect audio signals within a period of time according to the preset time threshold.

It should be noted that, in the embodiment of the present application, the preset audio signal may include a pulsed sound wave signal or an encoded sound signal.

Step 103: Determine the switch detection result according to the target audio signal; wherein the switch detection result is used to determine the switch state of the earphone box.

In the embodiment of the present application, after the wireless earphone performs audio collection through the sound receiving module and obtains the target audio signal, the switch detection result can be determined according to the target audio signal.

It should be noted that, in the embodiment of the present application, the switch detection result determined by the wireless headset based on the target audio signal may be used to determine the switch state of the headset box. That is to say, in some embodiments of the present application, the wireless earphone only needs to use the sound generating module and the sound receiving module configured in the wireless earphone to realize the detection of the on-off state of the earphone box. In some embodiments, it is required that the earphone box itself has the function of detecting the opening and closing of the cover. Compared with the prior art, there is no need to add a Hall sensor in the wireless earphone, so the shape and structure of the wireless earphone will not be affected, nor will it not work normally under high temperature conditions.

Further, in the embodiment of the present application, when the wireless headset determines the switch detection result according to the target audio signal, if the target audio signal includes a preset audio signal, the wireless headset can determine that the switch detection result is on, that is, the headset box is On state; if the target audio signal does not include the preset audio signal, the wireless headset can determine that the switch detection result is off, that is, the headset box is off.

It is understandable that, in the embodiment of the present application, if the earphone box is turned on, the sound receiving module can collect the preset audio signal emitted by the sound emitting module. Therefore, when the target audio signal collected by the sound receiving module includes the preset audio signal When the audio signal is set, it can be determined that the switch detection result is on; accordingly, if the earphone box is closed, the cover of the earphone box will block the transmission of audio signals between the sound module and the sound module, and the sound module The preset audio signal from the sound module cannot be received. Therefore, when the target audio signal collected by the sound module does not include the preset audio signal, it can be determined that the switch detection result is closed.

It is understandable that, in some embodiments of the present application, in an ideal state, if the earphone box is closed, the sound receiving module cannot receive the preset audio signal sent by the sound emitting module, and at the same time, the sound receiving module cannot receive either To other audio signals, therefore, when the target audio signal collected by the radio module is empty, it can be determined that the switch detection result is closed.

Further, in the embodiment of the present application, it can be considered that when the earphone box is closed, the sound receiving module can still receive some audio signals. Then, the wireless earphone needs to pre-check the target audio signal collected by the sound receiving module. It is assumed that the signal strength of the audio signal is determined to further determine the switch state of the earphone box.

In a feasible implementation manner, if the preset audio signal included in the target audio signal collected by the sound receiving module is greater than the preset threshold, it is determined that the switch detection result is turned on; accordingly, if the target audio signal collected by the sound receiving module includes If the preset audio signal of is less than or equal to the preset threshold, it is determined that the switch detection result is closed.

In this embodiment, the preset audio signal can be collected when the earphone box is closed and opened, but the amount of collection is different. Therefore, the threshold range of the collection can be obtained according to the experiment, the preset threshold can be set, and then when the collected preset audio When the signal is greater than or equal to the preset threshold, the cover of the earphone box is considered to be open. When the collected preset audio signal is less than the preset threshold, the cover of the earphone box is considered to be closed. The preset threshold may be the signal strength threshold. The threshold used to measure the strength of the preset audio signal collected.

In summary, in the embodiments of the present application, the wireless earphone can directly perform the switch detection of the earphone box using its own configured sound generating device and sound receiving device, without adding additional devices such as a Hall sensor. On the one hand, it significantly reduces The production cost of the wireless headset, on the one hand, greatly reduces the size and structural complexity of the wireless headset, on the other hand, it avoids the risk of failure of the magnet after a period of use, and effectively improves the reliability of the wireless headset.

The embodiment of the application provides a switch detection method. The switch detection method is applied to a wireless headset.

Based on the above-mentioned embodiments, another embodiment of the present application proposes a switch detection method, which is applied to a wireless headset. FIG. 5 is a schematic diagram of the implementation process of the switch detection method. As shown in FIG. 5, the wireless After the headset determines the switch detection result according to the target audio signal, that is, after step 103, the method for the wireless headset to perform switch detection may include the following steps:

Step 104: Control the connection state with the terminal according to the switch detection result.

In the embodiment of the present application, after the wireless headset determines the switch detection result according to the target audio signal, it can continue to control the connection state between the wireless headset and the terminal according to the switch detection result.

For example, if the switch detection result is on, the wireless headset and the headset box are controlled to be in a Bluetooth connection state; if the switch detection result is off, the wireless headset and the headset box are controlled to be in a Bluetooth disconnected state.

It can be understood that, in the embodiments of the present application, the terminal may be any device that has communication and storage functions and is provided with a touch screen. For example: tablet computers, mobile phones, e-readers, remote controls, personal computers (PC), notebook computers, in-vehicle devices, Internet TVs, wearable devices and other devices.

It should be noted that, in the embodiment of the present application, when the wireless headset controls the connection state with the terminal, it may specifically include establishing a connection with the terminal, or disconnecting the terminal.

Further, in the embodiment of the present application, the wireless headset can first determine its real-time connection status with the terminal. Specifically, before the wireless headset controls the connection state with the terminal according to the switch detection result, it needs to determine the real-time connection state first. Among them, the real-time connection status is the current connection status between the wireless headset and the terminal. Illustratively, the real-time connection status may be connected or unconnected.

It should be noted that in the embodiment of the present application, after the switch detection result and the real-time connection status are determined, when the wireless headset controls the connection status with the terminal according to the switch detection result, if the switch detection result is ON and the real-time connection status is If it is not connected, the wireless headset can establish a connection with the terminal. Specifically, the wireless headset can establish a connection with the terminal by turning on Bluetooth.

It is understandable that, in the embodiment of the present application, when the switch detection result is turned on and the real-time connection status is not connected, the wireless headset can be considered as not being used yet, but the headset box has the lid open, and the wireless headset is about to be used Therefore, the wireless headset needs to establish a connection with the terminal, and the wireless headset can directly broadcast and turn on Bluetooth, so that the surrounding terminals can recognize the wireless headset and connect with the terminal.

Further, in the embodiment of the present application, when the switch detection result is turned on and the real-time connection status is connected, the wireless headset can continue to maintain the connection with the terminal.

It should be noted that, in the embodiment of the present application, after the switch detection result and the real-time connection status are determined, when the wireless headset controls the connection status with the terminal according to the switch detection result, if the switch detection result is closed and the real-time connection status is Connected, you can disconnect from the terminal by turning off Bluetooth. Then the wireless headset can be disconnected from the terminal. Specifically, the wireless headset can be disconnected from the terminal by turning off Bluetooth.

It is understandable that, in the embodiment of the present application, when the switch detection result is closed and the real-time connection status is connected, the wireless headset can be considered to be currently in use, but the headset box is closed with the cover, and the wireless headset is about to end use Therefore, the wireless headset needs to be disconnected from the terminal to save power consumption, and the wireless headset can turn off the Bluetooth, so that the connection with the terminal can be disconnected.

Further, in the embodiment of the present application, when the switch detection result is closed, and the real-time connection status is not connected, the wireless headset may continue to be disconnected from the terminal.

It can be seen that, in the embodiment of the present application, if the wireless earphone is placed in the earphone box for charging, once the cover of the earphone box is opened, it can be considered that the wireless earphone needs to be used, and therefore the wireless earphone needs to be connected to the terminal. Correspondingly, if the wireless headset is put into the headset box after use, once the cover of the headset box is closed, it can be considered that the wireless headset needs to start charging. In order to save power consumption, the wireless headset can be disconnected from the terminal. In other words, to ensure that the wireless headset can accurately perform switch detection, it can establish a connection with the terminal in time when it needs to be used, and it can also be disconnected from the terminal in time when it needs to be charged, thus improving the intelligence of the wireless headset. It also saves power consumption.

In the embodiment of the present application, further, the preset audio signal generated and emitted by the sound generating module may include a pulsed sound wave signal or an encoded sound signal.

It should be noted that, in the embodiment of the present application, in order to prevent the preset audio signal generated and emitted by the sound module from being heard by the user, the audio signal larger than 20k may be emitted, and the audio signal is encoded, that is, the preset audio The signal is an encoded sound signal.

It should be noted that, in the embodiment of the present application, since the encoded signal needs to be parsed, some Bluetooth chips have weak data processing capabilities. Therefore, the preset audio signal may also be a pulsed sound wave signal. Specifically, the sound module can send out a pulsed sound wave signal. After the sound module continues to collect the audio signal, it can analyze the acquired target audio signal to obtain its corresponding pulse parameter to further determine the switch detection result based on the pulse parameter .

Specifically, in the embodiment of the present application, when the wireless headset determines the switch detection result according to the target audio signal, it can first determine the pulse parameter corresponding to the target audio signal; wherein, the pulse parameter can be characterized in a preset time interval (such as 1s) The number of high-level sonic pulses in the target audio signal accumulated and counted within. Further, after the wireless headset determines the pulse parameter corresponding to the target audio signal, the pulse parameter can be compared with the preset pulse threshold. If the pulse parameter is greater than or equal to the preset pulse threshold, the wireless headset can determine the switch detection result Is turned on.

It is understandable that in the embodiment of the present application, the user's hand may block the sound receiving module during the process of putting the wireless earphone into the earphone box. If it is simply considered that the sound receiving module cannot receive the preset audio signal, then To make sure that the earphone box is closed, it may cause misrecognition and wrong switch detection results. In order to reduce the misrecognition rate of the wireless earphone on the switch state of the earphone box, the wireless earphone can be detected by the power module after it is put in the earphone box. After the excitation voltage input by the earphone box, there needs to be a period of time before the radio module can receive the preset audio signal, and then for a period of time (such as a few seconds) the radio module cannot recognize the preset audio signal before the wireless headset determines The switch detection result is closed. It can also be determined by the number of times the radio module collects the preset audio signal, and the cover is confirmed to be closed or open only after the preset number of times is reached continuously.

The embodiment of the application provides a switch detection method. The switch detection method is applied to a wireless headset. The wireless headset includes a sounding module, a sound receiving module, and a power supply module. After the power supply module detects the excitation voltage input by the earphone box, it is generated by the sounding module Preset audio signal; audio collection is performed by the radio module to obtain the target audio signal; wherein the target audio signal is used to determine the situation in which the radio module obtains the preset audio signal; the switch detection result is determined according to the target audio signal; wherein, The switch detection result is used to determine the switch state of the earphone box. It can be seen that, in the embodiment of the present application, after receiving the excitation voltage of the earphone box, the wireless earphone can send out a preset audio signal through the sound module, and obtain the target audio signal through the sound module, and finally can directly Determine the switch detection result of the earphone box according to the target audio signal. Since the sound module and the sound module can share the speakers and microphones of the headset itself to save hardware costs, it is not easy to fail under high temperature or long-term use, so that the shape and structure of the wireless headset can be guaranteed without affecting the shape and structure of the wireless headset. The accuracy of switch detection of wireless earphones effectively improves the reliability of wireless earphones.

Based on the foregoing embodiment, yet another embodiment of the present application proposes a switch detection method, which is applied to a headset box. Specifically, the earphone box includes a power supply module. When the earphone box assists the wireless earphone to perform switch detection, the power supply module transmits an excitation voltage to the wireless earphone connected to the earphone box, so that the sound module of the wireless earphone generates a preset audio signal, and the wireless earphone receives The sound module collects the audio signal to obtain the target audio signal, and the target audio signal is used to determine the situation in which the sound receiving module obtains the preset audio signal, so that the wireless earphone knows the state of the opening and closing cover of the earphone box.

Further, in the embodiment of the present application, the excitation voltage may be the charging voltage (for example, 5V) output when the earphone box is in the power supply state; the excitation voltage may also be the first preset voltage output when the earphone box is in the dormant state. , The first preset voltage may be a voltage that cannot supply power to the earphone; the excitation voltage may also be a second preset voltage output by the earphone box after detecting that the cover is opened or closed by itself, and the second preset voltage may be It is a voltage value that is different from the charging voltage or the voltage output in the sleep state.

It is understandable that in this application, for the case where the excitation voltage is the charging voltage (for example, 5V voltage) transmitted by the wireless earphone receiving the earphone box, the wireless earphone is put into the earphone box for charging, and when the wireless earphone receives the earphone box transmission After the charging voltage is reached, the wireless headset generates a preset audio signal through the sound module, and collects the audio signal through the sound module to obtain the target audio signal, so that the wireless headset can determine the open state of the charging box, and then determine the connection with the mobile phone and other terminals. The Bluetooth connection status of the device.

It is understandable that in this application, for the case where the excitation voltage is the first preset voltage transmitted by the earphone box to the earphone when the earphone box is in the dormant state, the earphone box will still send out when the earphone box is in the dormant state. A first preset voltage, the first preset voltage may not be enough to enable the earphone box to supply power to the wireless earphone, but can stimulate the sound generating device of the wireless earphone to emit a preset audio, and the sound receiving device performs audio collection to obtain the target audio signal , So that the wireless headset can determine the open status of the charging box, and then determine the Bluetooth connection status with terminal devices such as mobile phones.

It is understandable that, in this application, for the case where the excitation voltage is the second preset voltage when the earphone box itself detects the opening and closing of the cover, the wireless earphone and the earphone are placed in the earphone box. When the earphone box detects that the cover is closed, the earphone box sends the second preset voltage to the wireless earphone. After the wireless earphone receives the second preset voltage, the sound module of the wireless earphone generates the preset audio. The sound receiving module collects audio signals to obtain target audio. Since the cover of the earphone box is closed, the collection of the preset audio signal is affected, so that it can be judged that the earphone box is closed and the Bluetooth connection is disconnected. When the earphone box is opened, the second preset voltage is sent to the wireless earphone in the earphone box, so that the sound module of the wireless earphone generates the preset audio, and the sound module of the wireless earphone collects audio signals to obtain the target audio. Since the earphone box is opened, the collection of the preset audio signal will not be affected, so it is judged that the earphone box is opened and the Bluetooth is connected back. This implementation manner can also be applied when the earphone box is in a sleep state, when the earphone box is opened or closed, the earphone box transmits the second preset voltage to the earphone. The second preset voltage may be a voltage value different from the charging voltage and the first preset voltage.

It is understandable that, in the above-mentioned embodiment, the earphone box itself needs to have the cover opening detection function, so that the excitation voltage can be sent to the wireless earphone in time when the cover opening and closing is detected, so that after the wireless earphone is placed in the earphone box, its sound device The sound receiving device does not need to continuously send out and collect preset audio signals, but only send out and collect preset audio signals after the cover of the earphone box is opened and closed, which can reduce the power consumption of wireless earphones. In addition, compared with the prior art , There is no need to add sensors such as infrared and Hall on the earphone, but the speaker and microphone of the wireless earphone can be reused to realize the earphone detection, which can reduce the weight of the wireless earphone.

The embodiment of the application provides a switch detection method, which is applied to a headset box. The headset box includes a power supply module. The headset box transmits an excitation voltage to the wireless headset connected to the headset box through the power supply module, so that the sound generating module of the wireless headset generates The audio signal is preset, and the radio module of the wireless earphone collects the audio signal to obtain the target audio signal. The target audio signal is used to determine the situation where the radio module obtains the preset audio signal, so that the wireless earphone knows the switch of the earphone box Cover state. It can be seen that, in the embodiment of the present application, after receiving the excitation voltage of the earphone box, the wireless earphone can send out a preset audio signal through the sound module, and obtain the target audio signal through the sound module, and finally can directly Determine the switch detection result of the earphone box according to the target audio signal. Since the sound module and the sound module can share the speakers and microphones of the headset itself to save hardware costs, it is not easy to fail under high temperature or long-term use, so that the shape and structure of the wireless headset can be guaranteed without affecting the shape and structure of the wireless headset.
