Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

To facilitate understanding of the present solution, the present application first introduces, through fig. 1, a headset to which the solution provided in the following of the present application is applicable:

fig. 1 includes: the microphone comprises an earphone housing 101, a feedforward MIC102, a battery 103, a call MIC104, a circuit board 105, a loudspeaker 201, a loudspeaker diaphragm 202, a sound outlet pipe head end 203, an earplug silicone sleeve 204, a sound outlet pipe tail end 205 and a feedback MIC 206.

The feedforward MIC102 is often referred to as FF MIC (Feed Forward MIC) and the feedback MIC206 is often referred to as FB MIC (Feed Back MIC). The feedforward MIC and the feedback MIC are commonly present on one earphone as part of an Active Noise Cancellation (ANC) solution for the earphone.

It can be seen that the feed-forward MIC is arranged on the side of the whole earphone facing away from the deep ear canal of the user, while the feedback MIC is arranged on the side of the whole earphone facing towards the deep ear canal of the user, in particular, the feedback MIC206 is arranged near the head end 203 of the sound outlet duct of the earphone speaker 201.

There are also some headsets with active noise reduction that are not provided with a feedback MIC or are not provided in the position shown in fig. 1, for which the feedback MIC addition or position adjustment can be made according to the structure shown in fig. 1.

Referring to fig. 2, fig. 2 is a flowchart of an earphone wearing detection method according to an embodiment of the present application, where an execution main body of each step shown in fig. 2 is an earphone, and the method includes the following steps:

s101: when a sound transmission instruction is received, controlling a feedback MIC on the earphone to be in an open state, and picking up the actual environmental noise intensity through the feedback MIC;

the sound introduction instruction here indicates that an audio signal is about to be introduced into the headset, in other words, the sound introduction instruction here indicates that the headset is about to be in an operating state or a use state. Specifically, the method may include receiving a call instruction (including an incoming call and an outgoing call), and a play instruction (e.g., a video play instruction, an audio play instruction, etc.) of various applications having audio signals when data connection (including a wireless connection including bluetooth and a wired connection including a data line) is established with a terminal (e.g., a smart mobile terminal such as a smart phone, and a fixed terminal such as a PC) in various manners.

From the above description of the earphone structure shown in fig. 1, it can be seen that once the earphone is in a wearing state, the sound outlet tube end 205 is in a closed state due to penetrating into the ear canal of the user, and the closed state indicates that external environmental noise cannot be easily picked up by the feedback MIC206 through the opening of the sound outlet tube end 205. Conversely, once the earphone is in an unworn state, the sound outlet tube end 205 will be in an open state and in direct communication with the external environment, and the ambient noise will be easily picked up by the feedback MIC206 through the sound outlet tube end 205. Therefore, whether the earphone is worn or not, there is a clear difference in the intensity of the environmental noise picked up by the feedback MIC206 due to physical reasons. The earphone is fully utilized to judge whether the earphone is in a wearing state or not.

Therefore, after receiving the sound incoming signal, the feedback MIC on the earphone is controlled to be in an on state, so that the feedback MIC in the on state can effectively pick up the actual environmental noise intensity.

S102: judging whether the actual environmental noise intensity is greater than the preset environmental noise intensity, if not, executing S103;

the preset environmental noise intensity is obtained by calculating the environmental noise intensity respectively picked up by the feedback MIC when the earphone is in a wearing state and an unworn state. That is, the preset environmental noise intensity calculated according to the environmental noise intensities respectively picked up when the earphone is in the wearing state and the non-wearing state is used as a measure for the actual environmental noise intensity in the application, so as to determine whether the earphone is in the critical value of the wearing state. Due to the complexity of the actual application scenario, the environmental noise intensities acquired when the wearing state and the non-wearing state of the critical value are calculated are generally obtained in a laboratory environment, so that the problem that the preset environmental noise intensity calculated based on the environmental noise intensity obtained in a certain environment is not suitable for other application scenarios is avoided as much as possible.

Since the preset ambient noise strength is used for measuring the magnitude of the actual ambient noise, and whether the earphone is in the wearing state is determined according to the magnitude comparison result, so as to play a role of a critical value, the preset ambient noise strength obtained by calculating the ambient noise strength respectively acquired by the feedback MIC when the earphone is in the wearing state and the non-wearing state is calculated, and as long as the purpose can be achieved, the application does not limit a specific calculation mode.

In an extreme case, the correct conclusion that the earphone is in the unworn state may be obtained based on only the first environmental noise strength acquired by the single feedback MIC when the earphone is in the worn state, and the correct conclusion that the earphone is in the unworn state may be obtained based on all the actual environmental noise strengths whose values are greater than the first environmental noise strength, or the correct conclusion that the earphone is in the worn state may be obtained based on only the second environmental noise strength acquired by the single feedback MIC when the earphone is in the unworn state, and the correct conclusion that the earphone is in the worn state may be obtained based on all the actual environmental noise strengths whose data are less than the second environmental noise strength. It should be understood that due to the complexity in the actual application scenario, a higher error rate of the result often exists in the discrimination mode based on the single threshold, and therefore, it would be an ideal scheme to calculate a compromise preset ambient noise strength according to the first ambient noise strength and the second ambient noise strength.

One implementation, including but not limited to, may be seen in the flow chart shown in fig. 2:

s201: picking up a first environmental noise intensity when the earphone is in a wearing state through a feedback type MIC;

s202: picking up the second ambient noise intensity when the earphone is not worn through a feedback type MIC;

s203: and taking the average value of the first environmental noise intensity and the second environmental noise intensity as the preset environmental noise intensity.

As shown in fig. 2, the present application takes the average of the first ambient noise intensity and the second ambient noise intensity as the preset ambient noise intensity, and thus determines that all earphones picking up the actual ambient noise intensity that is not greater than the preset ambient noise intensity are in the wearing state, and conversely determines that all earphones picking up the actual ambient noise intensity that is greater than the preset ambient noise intensity are in the non-wearing state. The calculation mode of the mean value is solved, so that the preset environmental noise intensity serving as the intermediate value of the first environmental noise intensity and the second environmental noise intensity has a better redundancy degree, and the misjudgment rate can be reduced.

Certainly, in some special application scenarios, the mode of taking the mean value as the critical decision value may not be completely applicable, so that the calculation formula may be fine-tuned according to the deviation of the actual situation to the decision result, for example, by respectively allocating weights to the first ambient noise intensity and the second ambient noise intensity, and adjusting the respective weights according to the different application scenarios, a more reasonable and more accurate preset ambient noise intensity (i.e., the critical decision value) may be calculated by a weighting calculation method.

Of course, a plurality of preset environmental noise intensities corresponding to different application scenes may also be directly preset in the headset, so that when the headset can know the type of the current application scene, the corresponding preset environmental noise intensities are flexibly selected for discrimination.

S103: and judging that the earphone is in a wearing state, and controlling the call MIC and the feedforward MIC on the earphone to be in an opening state.

This step is established on the basis that the actual environmental noise intensity is not greater than the preset environmental noise intensity as a result of the determination in S102, which indicates that the environmental noise intensity picked up by the feedback MIC is relatively small, and then it is deduced that the end 205 of the earphone sound outlet tube has penetrated into the ear canal of the user, and the external environmental noise cannot be easily picked up by the feedback MIC through the end 205 of the sound outlet tube due to penetration into the ear canal of the user. Therefore, the earphone where the feedback type MIC is located can be judged to be in a wearing state. On the premise of receiving the sound incoming instruction, the call MIC and the feedforward MIC on the earphone are controlled to be in an open state, so that the earphone can be normally used by a user.

On the contrary, when the environmental noise strength is greater than the preset environmental noise strength, it indicates that the environmental noise strength picked up by the feedback MIC is larger, and then the fact that the earphone sound outlet pipe end 205 is currently exposed to the external environment can be deduced, and the external environmental noise can be easily picked up by the feedback MIC through the sound outlet pipe end 205 due to the exposure to the external environment. Therefore, the earphone where the feedback type MIC is located can be judged to be in an unworn state. Even if the earphone is in a normal working state according to the received sound transmission instruction, the electric quantity is wasted only when the user does not wear the earphone and controls the conversation MIC and the feedforward MIC to be in an open state, so that when the earphone is judged to be in a non-wearing state, the conversation MIC and the feedforward MIC are controlled to be in a closed state, the power consumption is reduced as much as possible, the electric quantity is saved, and the normal use time is prolonged.

Furthermore, the earphone is in a normal working state according to the received sound transmission instruction, so that the received sound signal is transmitted to the user through the earphone or the sound signal of the user is collected and transmitted back to the connected equipment, but the operation is well realized because the earphone is not worn. Therefore, after the call MIC and the feed-forward MIC are controlled to be in the closed state, the prompt information that the earphone is not worn can be returned to the sending end of the sound incoming instruction, and the user is reminded to wear the earphone in time through the prompt information. Furthermore, other energy-consuming components on the earphone which is not worn can be controlled to be in a low-power-consumption standby state or a closed state, so that the electric quantity of the earphone which is not worn can be further saved. Wherein, the other energy consumption components include but not limited to at least one of a vibration unit, a display unit and a sound production unit on the earphone.

According to the earphone wearing detection method provided by the embodiment, the detection method is different from a detection mode of an additional functional component in the prior art, the feedback type MIC for realizing active noise reduction arranged on the earphone is fully utilized, and whether the earphone is in a wearing state or not can be well distinguished according to the intensity of the environmental noise collected by the earphone based on the setting position of the feedback type MIC (once the earphone is in the wearing state, the tail end of the sound outlet pipeline is in a closed state due to penetrating into an ear canal). Therefore, the scheme provided by the application does not need to add an additional functional component on the earphone, meets the design idea of miniaturization and lightness, does not bring extra operation power consumption because of the additional functional component, and can obtain a better wearing detection result of accuracy because of the fully utilized setting position of the feedback MIC.

On the basis of the above embodiments, the present application also provides a corresponding headphone wear detection method for a binaural headphone in an actual application scenario, please refer to the flowchart shown in fig. 4, which includes the following steps:

s301: when a sound transmission instruction is received, controlling both a left ear feedback type MIC and a right ear feedback type MIC to be in an opening state, and picking up the actual ambient noise intensity of the left ear and the actual ambient noise intensity of the right ear through the left ear feedback type MIC and the right ear feedback type MIC respectively;

s302: judging whether the actual environmental noise intensity of the left ear is greater than the preset environmental noise intensity, if so, executing S304, otherwise, executing S305;

s303: judging whether the actual ambient noise intensity of the right ear is greater than the preset ambient noise intensity, if so, executing S307, otherwise, executing S306;

s304: judging that the left ear earphone is not worn, and controlling a call MIC and a feedforward MIC on the left ear earphone to be in a closed state;

s305: judging that the left ear earphone is in a wearing state, and controlling a call MIC and a feedforward MIC on the left ear earphone to be in an opening state;

s306: judging that the right ear earphone is in a wearing state, and controlling a call MIC and a feedforward MIC on the right ear earphone to be in an opening state;

s307: and judging that the right ear earphone is in an unworn state, and controlling the call MIC and the feedforward MIC on the right ear earphone to be in a closed state.

In this embodiment, a scheme of returning, to the sending end of the sound incoming instruction, prompt information that the headphones are not worn is further provided through S308 for a case that the headphones are not worn on the premise that the headphones receive the sound incoming signal, in order to ensure that the user can timely obtain effective sound information.

In addition, except for the accumulation of the two results, other accumulation modes can obtain the conclusion that only one earphone is in a wearing state and the other earphone is in an unworn state, and as the sound information can still be transmitted to the user through the earphone in the wearing state, the aim of saving the electric quantity can be achieved only by controlling the conversation MIC and the feedforward MIC of the other unworn earphone to be turned off.

It can be seen that, for the two-ear headphones, the judgment process is respectively carried out on the left-ear headphone and the right-ear headphone, and the left-ear headphone and the right-ear headphone do not have a dependency relationship, so that even if the two-ear headphones are worn by a single ear, the same purpose can be completely realized.

In order to deepen understanding of the scheme provided by the application, a specific implementation and determination process is further provided herein in combination with a specific application scenario, and this embodiment takes a scenario that an earphone needs to synchronize a phone access or dial of a mobile phone as an example:

typically, all MICs are turned off for the headset device to consume less power and save power. When the earphone and the mobile phone Bluetooth are in a connection state, and the mobile phone is in a telephone access or dialing state, the earphone device synchronously receives an instruction (a telephone access instruction or a dialing instruction) from a mobile phone end through a Bluetooth connection link, the earphone device MCU (a micro control unit in the earphone) sends the instruction to the DSP (a digital signal processor arranged on the earphone, similar to a CPU in a PC), an algorithm program command is executed, and the left and right ear feedback type MICs are automatically opened.

After the two feedback MICs of the left and right ear earphones are turned on, the intensity of the environmental noise picked up by the feedback MICs is assumed to be LxdB (decibel), wherein the intensity of the environmental noise picked up by the feedback MIC of the left ear earphone is L _ LxdB (decibel), and the intensity of the environmental noise picked up by the feedback MIC of the right ear earphone is R _ LxdB (decibel). The DSP in the earphone compares the values of L _ LxdB and R _ LxdB with L0dB respectively, and the comparison results are as follows:

the first condition is as follows: when L _ LxdB is less than L0dB and R _ LxdB is less than L0dB, the left ear and the right ear are both in the ear wearing state; meanwhile, the earphone MCU sends an instruction to open a call MIC and a feedforward MIC on the left ear earphone, or open a call MIC and a feedforward MIC on the right ear, or open all MICs of the left and right ears (the three conditions respectively correspond to certain earphones with MICs only on one of the left and right ears); after the telephone is connected/dialed, the earphone worn on the ear can be used for communication (the MCU sends an instruction to the DSP to execute the algorithm program command to open, and a multi-channel analog switch is utilized);

case two: when L _ LxdB is less than L0dB and R _ LxdB is greater than L0dB, the left ear earphone is judged to be in a wearing state; meanwhile, the earphone MCU sends an instruction to open a call MIC and a feedforward MIC, or open all MICs of the left ear and the right ear; after the call is connected/dialed, the left ear earphone worn on the ear can be used for communication;

case three: when L _ LxdB is larger than L0dB and R _ LxdB is smaller than L0dB, the right ear earphone is judged to be in a wearing state; meanwhile, the earphone MCU sends an instruction to open a right ear call MIC and a feedforward MIC, or open all MICs of the left ear and the right ear; after the telephone is connected/dialed, the right ear earphone worn on the ear can be used for communication;

case four: when L _ LxdB is more than L0dB and R _ LxdB is more than L0dB, the left and right earphones are judged to be in an unworn state; meanwhile, the earphone MCU sends an instruction, the instruction is transmitted to the mobile phone through the Bluetooth connection link, and the screen of the mobile phone displays that' please wear the earphone! ". And when the earphone wearer wears the earphone according to the prompt, the judgment process is carried out.

Wherein, the acquisition process of L0dB is as follows:

the method is determined by actual tests in a laboratory simulation noise environment: when the earphone is normally worn on a human ear, only a small amount of external environment noise leaks into the tail end 205 of the sound outlet pipeline due to the coupling of the earplug sleeve and the ear canal of the human ear, and then enters the feedback type MIC through the sound outlet pipeline, and the intensity of the environment noise picked up by the feedback type MIC in the state is measured to be L1dB (decibel). Then, the earphone is taken off from the human ear, the earphone is placed in a free state, the tail end 205 of the sound outlet pipeline is in a free open environment, external environment noise is easy to enter from the tail end 205 of the sound outlet pipeline, then the external environment noise enters the feedback type MIC through the sound outlet pipeline, and the intensity of the environment noise picked up by the feedback type MIC in the state is measured to be L2dB decibels. From the theoretical and actual measured data, it is found that L2dB is certainly larger than L1dB, and further, L0dB is set to (L1dB + L2dB)/2 as a threshold.

Because the situation is complicated and cannot be illustrated by a list, a person skilled in the art can realize that many examples exist according to the basic method principle provided by the application and the practical situation, and the protection scope of the application should be protected without enough inventive work.
