DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0017] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0018] In the description of the present invention, the term "for example" is used to mean "used as an example, illustration or explanation". Any embodiment described as "for example" in the present invention is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any technician in the field to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present invention.

[0019] Embodiment 1: like Figure 1 As shown, an embodiment of the present invention provides a Bluetooth headset noise reduction prompt method, which is applied to a Bluetooth headset, wherein the Bluetooth headset is communicatively connected with a first object, and includes the steps of: S10: when the noise reduction mode is turned on and it is detected that the user is in a sleeping state, the prompt target time and the prompt audio are retrieved from the first object; S20: or when the noise reduction mode is turned on, and it is detected that the user is in a sleeping state, and audio is played at the same time, the prompt target time and the prompt audio are retrieved from the first object, and the real-time playing audio is recorded and stored; S30: When it is detected that the connection with the first object is disconnected, the real-time audio is played, and when the prompt target time is met at the first real-time moment, the prompt audio is played until the user is awake.

[0020] Specifically, the first object refers to a device that is connected to the Bluetooth headset and transmits audio to the Bluetooth headset. The communication connection method includes Bluetooth connection, wireless connection methods such as wireless LAN shared connection, and wired connection. The first object can be a mobile phone, tablet, computer, MP4 and other devices. When the Bluetooth headset turns on the noise reduction mode and detects that the user is in a sleeping state, the user's preset prompt target time and the user's preset prompt audio are retrieved from the first object when in a connected state.

[0021] When it is detected that the connection with the first object is disconnected and the real time recorded by the clock, that is, the first real time, is equal to the prompt target time, the prompt audio is played until the user is awake.

[0022] In another implementation, the first object continuously sends the real-time moment to the Bluetooth headset. If the real-time moment is not sent at a certain time, it is deemed to be disconnected. When the connection is disconnected, the time difference between the prompt target time and the real-time moment when the connection is last received is calculated. At the same time, the timer of the Bluetooth headset starts counting from zero. When the time difference is met, the first real-time moment is deemed to be equal to the prompt target time.

[0023] Specifically, the detailed method of determining whether the user is in a sleeping state is as follows: By detecting the blood oxygen, heart rate, and respiratory rate data of the user wearing the Bluetooth headset, it is analyzed whether the user's blood oxygen, heart rate, and respiratory rate belong to the pre-set blood oxygen interval, heart rate interval, and respiratory rate interval. If so, the user is in a sleeping state, otherwise, the user is in an awake state. In detail, the blood oxygen, heart rate, and respiratory rate data of the user wearing the Bluetooth headset can be detected by a detection unit integrated in the Bluetooth headset, or by other devices and then communicated with the Bluetooth headset for transmission.

[0024] Specifically, when the noise reduction mode is turned on, and it is monitored that the user is in a sleeping state, and the Bluetooth headset is still playing audio in real time, the real-time audio is stored and named real-time audio; when it is detected that the connection with the first object is disconnected, the recorded real-time audio continues to be played.

[0025] For example, a mobile phone is connected to a Bluetooth headset, and the audio played is sleep-inducing sounds such as the sound of firewood, thunder and rain, and waves in the forest; the mobile phone continuously transmits real-time time to the Bluetooth headset, and the Bluetooth headset can determine that the Bluetooth communication with the mobile phone is disconnected if it cannot receive the real-time time; after determining that the connection with the mobile phone is disconnected, it immediately connects to play the recorded audio, so as to avoid waking the wearer due to the sudden disappearance of the sleep-inducing sound, and the amplitude of the audio played at this time is consistent with the audio played before.

[0026] Further, such as Figure 2 As shown, S30 also includes the steps of: S31: Obtain the total power of the Bluetooth headset, the remaining power of the Bluetooth headset, and the power consumption of the Bluetooth headset; S32: Obtaining a first interval between the second real time and the prompt target time; S33: subtracting a preset proportion of the total power of the Bluetooth headset from the remaining power of the Bluetooth headset to obtain a target power; S34: Calculate the product of the power consumption of the Bluetooth headset and the first interval duration, and set it as the predicted power consumption; S35: When the target power is less than the predicted power consumption, the real-time audio is played according to the power consumption of the Bluetooth headset.

[0027] Specifically, after the Bluetooth headset is disconnected, if the battery of the Bluetooth headset is not enough to support the time node when the prompt audio sounds, then when the prompt target time is reached, the noise reduction mode will be turned off, and the user can hear the external prompt audio of the first object, and then continue to play according to the current power consumption mode.

[0028] The process of judging whether the power of the Bluetooth headset is sufficient to last until the prompt audio sounds is as follows: Obtain the total power of the Bluetooth headset, the remaining power of the Bluetooth headset and the power consumption of the Bluetooth headset, obtain the real-time moment recorded by the clock, store it as the second real-time moment, calculate the time difference between the second real-time moment and the prompt target time, and store it as the first interval duration; subtract the preset proportion of the total power of the Bluetooth headset from the remaining power of the Bluetooth headset to obtain the target power, calculate the product of the power consumption of the Bluetooth headset and the first interval duration to obtain the predicted power loss; when the target power is less than the predicted power loss, play the real-time audio according to the power consumption of the Bluetooth headset. Preferably, the preset proportion defaults to one tenth, and the preset proportion of the total power of the Bluetooth headset represents the power margin. Setting a 10% margin is reserved for subsequent playback of ringtones and execution of subsequent steps.

[0029] Furthermore, it also includes: when the target power is greater than or equal to the predicted power loss, the noise reduction level and the real-time audio playback are adjusted with the goal of reducing the power consumption of the Bluetooth headset.

[0030] Specifically, the adjustment methods to reduce the power consumption of Bluetooth headsets include conventional methods such as reducing the degree of noise reduction and reducing the amplitude of real-time audio playback.

[0031] Furthermore, the noise reduction level and the real-time audio playback adjustment are performed with the goal of reducing the power consumption of the Bluetooth headset, including: Monitor the environmental noise level and the user's sleep level, wherein the environmental noise level includes light noise level, medium noise level, and heavy noise level, and the user's sleep level includes a light sleep stage, a light-to-deep sleep stage, a deep sleep level, and a deep-to-light sleep stage; When the user's sleep level belongs to the light sleep stage, maintaining the noise reduction mode at an initial noise reduction level, and maintaining the real-time played audio at an initial audio amplitude; When the user's sleep level belongs to the light-to-deep stage, and the ambient noise level belongs to the light noise level, matching a first preset attenuation step length and a second preset attenuation step length according to the user's sleep level, reducing the initial noise reduction level according to the first preset attenuation step length, and reducing the initial audio amplitude according to the second preset attenuation step length; When the user's sleep level is in the light-to-deep stage, and the ambient noise level is in the medium noise level, matching the first preset attenuation step length according to the user's sleep level, reducing the initial noise reduction level according to the first preset attenuation step length, and maintaining the real-time playback audio at the initial audio amplitude; When the user's sleep level is in the light-to-deep stage, and the ambient noise level is in the heavy noise level, the noise reduction mode is maintained at the initial noise reduction level, and the real-time audio playback is maintained at the initial audio amplitude; When the user's sleep level is at the deep sleep level, and the ambient noise level is at the light noise level or the medium noise level, the noise reduction mode is maintained at the noise reduction level when entering the deep sleep level, and the audio amplitude of the real-time played audio is maintained at the audio amplitude when entering the deep sleep level; When the user's sleep level is at the deep sleep level and the ambient noise level is at the heavy noise level, the noise reduction mode is adjusted to half of the noise reduction level when entering the deep sleep level, and the real-time audio playback is adjusted to half of the audio amplitude when entering the deep sleep level; When the user's sleep level belongs to the deep to light sleep stage, the noise reduction mode is adjusted to 1.5 times the noise reduction level when entering the deep sleep level, and the audio amplitude of the real-time played audio is maintained at the deep sleep level, wherein when 1.5 times the noise reduction level at the deep sleep level is greater than the rated noise reduction level, it is adjusted to the rated noise reduction level.

[0032] Specifically, the ambient noise level is determined as follows: Light noise level: The actual volume is low or the noise is extremely low, but it can be completely filtered out by the Bluetooth headset itself. Medium noise level: The actual volume is medium to low to medium to high. It cannot be completely filtered out by the Bluetooth headset itself, but it is weak or the volume is transmitted to the wearer's eardrum. Noise severity: Loud or very low noise, which is still loud even after being filtered by Bluetooth headphones.

[0033] In detail, according to the interval to which the volume belongs, an environmental noise level calibration table corresponding to the volume level is constructed to achieve quantitative calibration of the environmental noise level.

[0034] The user's sleep level is determined as follows: Light sleep stage: A stage with a relatively light sleep level, which is characterized by a half-asleep and half-awake state. Users are more sensitive to external sounds, but in fact, users will consciously ignore the noise in this stage to ensure that they fall asleep.

[0035] Light to deep sleep stage: the transition stage from light sleep stage to deep sleep stage.

[0036] Deep sleep level: In the deep sleep stage, it is more difficult to wake up.

[0037] Deep to light sleep stage: The wearer is in the transition stage from deep sleep to light sleep after starting to perceive noise.

[0038] In detail, according to the intervals of the user's blood oxygen, heart rate, respiratory rate and other indicators, a calibration table of the user's sleep level corresponding to the intervals of the user's blood oxygen, heart rate, respiratory rate and other indicators is pre-built, which can quickly determine the user's sleep level.

[0039] Further, when the user's sleep level belongs to the deep to light stage, adjusting the noise reduction mode to 1.5 times the noise reduction level when entering the deep sleep level, and maintaining the audio amplitude of the real-time played audio at the deep sleep level, further comprising: When the noise reduction mode is adjusted to 1.5 times the noise reduction level when entering the deep sleep level, and the real-time audio is maintained at the audio amplitude when entering the deep sleep level, the user's sleep level still belongs to the deep to light sleep stage, the noise reduction mode is adjusted to the rated noise reduction level, and the real-time audio is adjusted to the initial audio amplitude.

[0040] Further, when it is detected that the connection with the first object is disconnected and the first real time meets the prompt target time, the prompt audio is played until the user is awake, including: When it is detected that the connection with the first object is disconnected and the first real time moment meets the prompt target time, separating the minimum loop audio unit of the prompt audio; The minimum loop audio unit is played until the user is awake.

[0041] Specifically, when the Bluetooth headset is disconnected from the first object, the time of the disconnection and the interval duration of the prompt target time are recorded, and a timer is started from the time of the disconnection. When the timer is equal to the interval duration, it is considered that the first real time meets the prompt target time.

[0042] Furthermore, in order to ensure the prompt effect, the minimum loop audio unit of the prompt audio is selected, and the minimum loop audio unit is set to be played continuously in a loop by the user wearing the Bluetooth headset until the user is awake.

[0043] Further, when it is detected that the connection with the first object is disconnected and the first real time meets the prompt target time, separating the minimum loop audio unit of the prompt audio also includes: Detect whether there is a ringing sound around; If the ringtone of the type is present, separating the ringtone of the type to obtain the minimum cyclic audio unit; Otherwise, separate the prompt audio to obtain the minimum loop audio unit.

[0044] Specifically, quasi-ringtones include alarm ringtones and telephone ringtones. These ringtones have the characteristic of looping playback. This characteristic can be used to distinguish quasi-ringtones. When the prompt target time is met, the first object will play the prompt audio externally. There are two situations here: the first is that the first object is not covered by anything, and the alarm ringtone is relatively loud, which can be better collected and identified by the microphone of the Bluetooth headset. At this time, the collected minimum loop audio unit of the quasi-ringtone is directly played as a prompt; the second is that the first object is covered, the ringtone is relatively small, and it cannot be collected by the microphone of the Bluetooth headset. At this time, the prompt audio is separated and the minimum loop audio unit is obtained to ensure the prompt effect.

[0045] Further, when it is detected that the connection with the first object is disconnected, the real-time playback audio is played, including: when it is detected that the connection with the first object is disconnected, the real-time playback audio minimum audio unit of the real-time playback audio is played.

[0046] Furthermore, it also includes: requesting in real time to establish a communication connection with the first object; when the communication connection is successfully established, stopping the process; when the communication connection fails to be established, continuing the process.

[0047] During the entire program running process, the Bluetooth headset is always trying to re-establish communication with the first formation. Once the communication is re-established, the steps of the embodiment of the present invention are terminated.

[0048] A Bluetooth headset noise reduction prompt method provided by an embodiment of the present invention has at least the following technical effects: 1. A Bluetooth headset noise reduction prompt method is provided, which is applied to a Bluetooth headset, and the Bluetooth headset is connected to a first object in communication, including: when the noise reduction mode is turned on and the user is detected to be in a sleeping state, the prompt target time and prompt audio are retrieved from the first object; when the connection with the first object is detected to be disconnected, and the first real-time moment meets the prompt target time, the prompt audio is played until the user is awake. The prompt time, prompt audio and playback audio set by the connection object are stored in real time, and the user can be prompted on time and the audio can continue to be played even if the connection is disconnected, achieving the technical effect of avoiding the situation where the user cannot hear the audio after the Bluetooth headset in the noise reduction mode is disconnected from the connection object.

[0049] 2. When the battery is low, the power consumption of the noise reduction function and the playback function is allocated to ensure that the power for playing the ringtone is adequately supplied.

[0050] 3. The noise reduction mode and the sleep-aiding sounds played are kept on during the wearer's entire sleep time. Compared with the solution of turning off / reducing the noise reduction level after disconnection to allow the user to hear the external alarm clock, this solution can better ensure the wearer's sleep experience.
