The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention. It is clear that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the present invention. The embodiment of the present invention provides an environmental sound reminding method. The sound environment of the external environment is used to remind the user of the external environment sound by using a preset reminding manner. The embodiment of the present invention further provides a corresponding mobile terminal. The details are described below separately. Embodiment 1 The basic flow of the environmental sound reminding method of the first embodiment of the present invention can be referred to FIG. 1. The environmental sound reminding method of the present embodiment mainly includes the following steps: Step 101: Collecting sound signals of an external environment in real time. The real-time sound signal of the external environment can be obtained by real-time recording, and the sound recording of the external environment of each time period can be obtained and stored. Of course, in the embodiment of the present invention, but not limited to the above manner, the sound signals of the external environment are collected. Step 102: Process the sound signal as a sound processing value according to a processing command corresponding to the reminding condition preset by the user. The mobile terminal provides different manners of reminding conditions according to its own software and hardware support capabilities. Reminder conditions include but are not limited to the following: Sensitivity reminder conditions, the user sets to, according to the volume of the sound or the size of the frequency to decide whether to remind the user, when the sound processing value (volume) of the detected sound signal reaches the user-set reminder The condition initiates the reminder; the change amount reminder condition, the user sets, according to whether the size of the change of the sound processing value (volume) of the sound signal in the detected environment reaches the reminder condition set by the user to decide whether to remind. Such as: small changes, medium changes and large changes. The voice recognition reminder condition is set by the user to, when the collected sound is compared with the pre-recorded sound, a reminder occurs when the similarity reaches a certain level. For example, the user Zhang San recorded the recordings of "Zhang San,, and "Xiao Zhang". When someone calls "Zhang San," or "Xiao Zhang,", the reminder occurs when the similarity reaches the set level. At this time, The user can be reminded to call Zhang three. When the user sets the reminder condition, the interface can provide some intuitive options for the user to select, or can be set by the user. For example, the user can set the reminder condition as: the sound volume intensity reaches the reminder door Reminders occur within a limited time. You can also use the text that is easier for the average user to understand. Select tiny, medium, noisy, or harsh sounds on the interface. Each option corresponds to a quantified reminder condition. The user preset reminder condition and the processing command are corresponding relationships, and the processing command includes a detection attribute and a calculation method, and the detection attribute indicates whether the attribute value of the sound signal is a volume size, a frequency size or a power size, and the detection attribute indicates a frequency of detecting the sound signal, Then, the attribute value of the sound signal is the frequency value of the sound signal. If the detection attribute is only the volume level of the sound signal, the attribute value of the sound is the volume value of the sound signal. The calculation method is a processing method for calculating the attribute value of the sound signal as the sound processing value, and the calculation method may be an average value according to the attribute value of the sound signal, or another calculation method for processing the attribute value of the sound signal. The sound processing value obtained by calculating the attribute value of the sound signal by the calculation method is more accurate and reliable. According to the corresponding condition of the reminder condition and the reminding condition preset by the user in the processing command, the corresponding processing command may be selected to process the sound signal. For example, if the alert condition is a frequency alert threshold, the attribute value of the sound signal is detected according to the detection attribute of the processing command according to the processing command corresponding thereto, and the attribute value of the sound signal is the frequency value of the sound signal, and then calculated according to the calculation. Method, calculating the frequency value of the detected sound signal. Of course, the corresponding relationship between the reminding condition and the processing command is preset in the foregoing manner in the embodiment of the present invention.

Step 103: Determine whether the sound processing value is within a range indicated by the user preset reminding condition, and if yes, proceed to step 104; for example, as shown in Table 1 below, the reminding condition that can be selected by the user setting is the sound intensity value. The thresholds are a, b, c, and d (a<b<c<d): The four thresholds correspond to tiny sounds, medium sounds, noisy sounds, and harsh sounds, as shown in Table 1 below.

After the user selects the reminder condition, the reminder range indicated by the user-selected reminder condition can be converted into

0, 1 , 2 , 3 are sent out. According to the preset setting, 0, 1 , 2, 3 are read as the corresponding range (dbm, intensity value), and the processed sound processing value is the sound intensity value. Whether the intensity value is within the range of reading, and when it is judged as YES, the process proceeds to step 104. Step 104: Perform an operation of reminding the user according to the preset reminding manner information. The user can set a reminder method suitable for himself, such as ringtone reminder, interface prompt, earphone reminder, vibration reminder, intelligent voice reminder, etc., store these reminder methods, and judge in step 103 When it is broken, the user is reminded according to the user setting or the system default reminder. Of course, in the embodiment of the present invention, including but not limited to, the user is reminded in the above manner. In this embodiment, the sound signal is processed by collecting the sound signal of the external environment in real time, and the sound processing value indicating the sound signal is obtained. When the sound processing value is in the reminding range indicated by the reminding condition, according to the reminding mode information提醒 Remind the user with a preset reminder method, which realizes the function of automatically reminding the user of the ambient sound information when the sound of the earphone is greatly restricted due to the sound of the earphone playback, so that the user can correctly handle the sound around the body in time, avoiding Miss important or urgent things.

The second embodiment of the environmental sound reminding method in the embodiment of the present invention includes: Step 201, obtaining user settings or The default reminder mode, reminder conditions, and time interval for detecting sound signals. There are many types of reminders, and users can set them to remind users of their sounds, images, vibrations, etc. Such as: ringtone reminder, a certain ringtone to remind the user; interface reminder, display a prompt message on the mobile terminal interface to remind the user; earphone reminder, play a certain sound through the earphone to the user's ear to remind the user; vibration reminder, vibration movement The terminal reminds the user; intelligent voice reminder, the mobile phone can pre-produce a frequency meter, and pre-produce some recordings, such as the human voice frequency, the frequency of the whistle, the frequency of the thunder, etc., when the sound frequency and frequency table of the detected sound signal When a match is made, the phone plays a corresponding recording to prompt. Such as: "Some around you call", "There is a car whistling around you" and so on. It will be understood that various reminders that can be conceived by those skilled in the art should be included in the embodiments of the present invention. The mobile terminal can provide different manners of reminding conditions according to its own software and hardware support capabilities. Reminder conditions include but are not limited to the following: Sensitivity reminder conditions, the user sets to, according to the volume of the sound or the size of the frequency to decide whether to remind the user, when the sound processing value (volume) of the detected sound signal reaches the user-set reminder The condition initiates the reminder; the change amount reminder condition, the user sets, according to whether the size of the change of the sound processing value (volume) of the sound signal in the detected environment reaches the reminder condition set by the user to decide whether to remind. Such as: small changes, medium changes and large changes. The voice recognition reminder condition, the user sets the sound and the preset The first recorded sound is compared, and a reminder occurs when the similarity reaches a certain level. For example, the user Zhang San recorded the recordings of "Zhang San" and "Xiao Zhang". When someone calls "Zhang San" or "Xiao Zhang," when the similarity reaches the set level, a reminder occurs. At this time, the user can be reminded to call Zhang San. When the user sets the reminder condition, the interface can provide some Intuitive options are available for the user to select, or they can be set by the user. For example, the user can set the reminder condition as: When the sound volume intensity reaches the reminder threshold, a reminder occurs, or a text that is easier for the average user to understand can be selected, and a small sound is selected on the interface. Medium sound, noisy sound or harsh sound, each option corresponds to a quantized reminder condition. The user preset reminder condition and processing command are corresponding, the processing command includes detection attribute and calculation method, and the detection attribute indicates the attribute value of the sound signal. Is the volume size, frequency size or power size, the detection attribute indicates the frequency of detecting the sound signal, then the attribute value of the sound signal is the frequency value of the sound signal, and if the detection attribute is only detecting the volume level of the sound signal, then the attribute value of the sound is The volume value of the sound signal. The calculation method is a processing method for calculating the attribute value of the sound signal as the sound processing value, and the calculation method may be averaging according to the attribute value of the sound signal, or other calculation method for processing the attribute value of the sound signal. The sound processing value obtained by the attribute value of the signal is more accurate and reliable. According to the corresponding condition of the reminder condition and the reminding condition of the user, the corresponding processing command can be selected to process the sound signal. For example, if the reminding condition is the frequency reminding threshold Then, according to the processing command corresponding thereto, detecting the attribute value of the sound signal according to the detection attribute of the processing command, the attribute value of the sound signal is the frequency value of the sound signal, and calculating the detected sound signal according to the calculation method. The frequency value. Of course, in the embodiment of the present invention, but not limited to, the corresponding relationship between the reminding condition and the processing command is preset in the above manner. The detecting precision is a time interval at which the user detects the attribute value of the sound signal, and the user can set the level. The interval between detections changes The accuracy of the sound signal is measured, and the higher the detection precision set by the user, the smaller the interval time of the sound signal of the level detection. Step 202: Collecting the sound signal of the external environment in real time; real-time recording the sound signal of the external environment through real-time recording In the embodiment of the present invention, the sound signal of the external environment is included in the embodiment of the present invention, but is not limited to the above manner to collect the sound signal of the external environment. Step 203: Find processing corresponding to the reminding condition command. The processing command includes a detection attribute and a calculation method, and the correspondence between the reminding condition and the processing command is pre-configured, and the sound processing value is obtained according to the detection attribute and the calculation method of the processing command corresponding to the reminding condition, for example, if the range of the reminding condition indication is The frequency range, then the processing command processing detection attribute is to detect the frequency value of the sound signal, calculate the detected frequency value according to the calculation method, and obtain the sound signal processing value. If the range indicated by the reminding condition is the volume level, the processing command detects the attribute of the sound signal. The value is the power value, and the power value is calculated as the sound processing value.

Step 204: Set a timer according to a time interval at which the sound signal is detected. The user setting information further includes accuracy information indicating a time interval at which the sound signal is detected. The detection timer is set according to this time interval.

Step 205: Detect an attribute value of the sound signal of the external environment according to the detection attribute every time the timer expires. The shorter the timer interval, the higher the accuracy of detecting the sound signal. Step 206: Calculate, according to the calculation method, an attribute value of the detected sound signal of the external environment as a sound processing value. The calculation method is used to process the attribute value of the sound signal to obtain a sound processing value that intuitively and accurately reflects the sound signal. For example, the user preset reminder condition is that the sound signal frequency is higher than 50 Hz. Then the reminder range indicated by the reminder condition is the frequency f 50HZ. Selecting a processing command corresponding to the alert condition, the detection attribute of the processing command indicating that the detected sound signal is a sound frequency value, and after obtaining the sound signal frequency value, processing the attribute of the detected sound signal by a calculation method (eg, averaging) The value, in order to obtain a sound processing value that is more intuitive and accurately reflects the sound signal. It should be noted that in order to avoid excessive and meaningless reminders caused by occasional narrow noise in the space, the processing logic of the processing command can be optimized, and the average algorithm of the sound processing value of the sound signal is optimized, for example, acquiring a sound. The sound processing value of the signal is much larger than the sound processing values of the two times before and after, and can be regarded as a bad point discarding, and the accuracy of the sound processing value detection is improved. Step 207: Determine whether the sound processing value is within a range indicated by the reminding condition, and if yes, proceed to step 208. Step 208: Perform an operation of alerting the user according to the preset reminding manner information. There are many types of reminders, such as: ringtone reminder, a certain ringtone to remind the user; interface reminder, display a prompt message on the mobile terminal interface to remind the user; earphone reminder, play a certain sound through the earphone Remind the user to the user's ear; vibrate the alarm, vibrate the mobile terminal to remind the user; intelligent voice reminder, the mobile phone can pre-produce a frequency meter, and pre-produce some recordings, such as the human voice frequency, the frequency of the whistle, the frequency of the thunder, etc. Various reminders that can be conceived by those skilled in the art should be included in the embodiments of the present invention.

Further, if it is determined in step 207 that the sound processing value is not within the range indicated by the reminding condition, the process proceeds to step 209.

Step 209, the user is not prompted. In this embodiment, by real-time collecting the sound signal of the external environment, the sound signal is processed according to the processing command, and the sound processing value indicating the sound signal is obtained, and when the sound processing value is in the reminding range indicated by the reminding condition, according to Remind the way information, remind the user with the preset reminder method, realize the function of automatically reminding the user of the ambient sound information when the sound of the earphone is greatly restricted due to the sound played by the earphone, so that the user can correctly make the sound of the surrounding side timely Deal with, avoid missing important or urgent things.

The mobile terminal of the embodiment of the invention for performing the above-mentioned environmental sound reminding method is described below. The structure of the mobile terminal is shown in FIG. 3, which is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention. The mobile terminal includes a signal collecting module 31. , a sound processing module 32 and a CPU module 33.

The determining unit 323 is configured to determine whether the sound processing value is within a range indicated by a reminder condition preset by the user. It should be noted that in order to avoid excessively meaningless reminders caused by occasional narrow noise in the space, the signal processing unit 322 can also optimize the processing logic of the processing command, and optimize the average algorithm of the sound processing value of the sound signal, for example The sound processing value of obtaining a sound signal is much larger than the sound processing value of the two times before and after, and can be regarded as a bad point discarding, thereby improving the accuracy of sound processing value detection. This improves the accuracy of sound processing and avoids unnecessary reminders. For ease of understanding, the above embodiments are described in detail in a specific application scenario: Scene 1, can also be seen in FIG. 2 and FIG. 3, assuming that Zhang San is on the way home late at night, while listening to music while walking, on the road. Quiet, Zhang San is preset to generate a reminder when the ambient volume level is greater than D. "Please note that there is a loud sound around, reminder. A volume intensity meter is prefabricated in the phone, and the volume intensity table corresponds to A, B, C and D four levels of volume intensity. Pre-made vocal recordings "Please note that there is a loud sound around." Step 201, the mobile terminal setting module 34 obtains user setting information, and the mobile terminal passes A, B, through the interface. The volume levels of the four levels C and D are displayed, and the user selects D, then D is stored as the reminder condition information in the CPU module 33. The user Zhang selects the reminder mode of the smart voice reminder, then the smart voice reminder is used as the reminder mode. The information is stored in the CPU module 33. Further, the accuracy information set by the user Zhang is 1 ms, and 1 ms is stored as accuracy information in the CPU module 33. Step 202 The sound signal collecting module 31 collects the sound signal of the external environment in real time, and the sound signal collecting module 31 records the external data, obtains the real-time recording segment, and stores the recorded segment in the CPU module 33. Step 203, the sound processing module 32 Obtaining a processing command from the CPU module 33, the CPU module 33, the user preset preset reminder condition information is the volume intensity D, and the reminder range indicated by the user-selected reminder condition may be converted into 0, 1, 2, 3 and sent to the sound processing module 32, and the sound processing module 32 is based on the advance The settings then convert 0, 1, 2, 3 into corresponding reminder conditions. A processing command corresponding to the reminder condition of the volume intensity D is obtained. The sound processing value processed by the processing command is the volume level of the sound signal.

Step 204, the sound processing module 32 sets a timer according to the detection interval 1 ms; Step 205, each time the timer expires, the current sound signal is detected from the collected data; Step 206, the sound signal detected by the processing step 205 is At time TO, the detected sound processing value of the sound signal is: volume intensity DO, and the data is recorded, the next time the timer expires, the data D1 is obtained, and so on, can be obtained for a period of time. Sound signal volume intensity data D0, Dl, ..., Dn. These volume intensity data are the sound processing values obtained after processing.

Step 207, the sound processing module 32 determines whether the sound processing value is in the reminder range indicated by the reminding condition, and the sound processing value is greater than the volume intensity value D. When the sound intensity Dn is detected, Dn>D, the process proceeds to step 208; Step 208, the sound processing module 32 generates a reminder trigger signal for reminding the user, sends a reminder trigger signal to the CPU module 33, and the CPU module 33 according to the stored reminder mode information.提醒Use the preset intelligent voice reminder to remind the user that the playback module of the mobile terminal plays "Please note that there is a loud sound around", which is transmitted to the user's three ears through the earphone.

Scene 2, can also refer to Figure 2 and Figure 3, 4, user Li Si wearing a mobile phone to use the mobile terminal to play the game, the mobile terminal pre-made the prompt text "Please note that there are abnormalities around the display interface. The user wants to display an alert on the display screen by "Please note that there is an abnormality around" when there is an abnormal sound in the surrounding environment. When the frequency of the sound signal in the surrounding environment changes too much, it is considered that there is an abnormal sound around.

Step 201: The setting module 34 of the mobile terminal acquires user setting information, and the user Li can set a frequency difference threshold E. When the frequency difference between the external ambient sound signal and the previous average frequency is greater than the threshold E, the surrounding sound is abnormal. E is stored in the CPU module 33 as the reminder condition information. When the user selects the reminder mode of the smart voice reminder, the smart voice reminder mode is stored as the reminder mode information in the CPU module 33. Further, the user-set accuracy information is 1 ms, and then 1 ms is stored as the accuracy information in the CPU module 33. Step 202: The sound signal collecting module 31 collects the sound signal of the external environment in real time, and the signal collecting module 31 records the external data to obtain a real-time recording segment, and stores the recorded segment in the CPU module 33. Step 203, the sound processing module 32 obtains a processing command in the CPU module 33, and the CPU module 33 reads the preset condition information of the user as the frequency difference threshold E, and the setting module can also convert the reminding range indicated by the user-selected reminding condition. 0, 1, 2, 3 are sent to the CPU module, and the CPU module converts 0, 1, 2, 3 into corresponding reminding conditions according to the preset settings. A processing command corresponding to the reminder condition being the frequency difference threshold E is obtained. The sound processing value processed by the processing command is the frequency difference value of the sound signal.

Step 204, the sound processing module 32 sets a timer according to the detection interval 1 ms; Step 205, each time the timer expires, the current sound signal is detected from the collected data; Step 206, the sound processing module 32 detects the current sound signal. The volume intensity DO, and record this data, the next time the timer expires, then the data D1 is detected, and so on, the sound signal volume intensity data D0, Dl, ..., Dn can be obtained for a period of time. These volume intensity data are the sound processing values obtained after processing. At the same time, the average sound intensity S0, S1, ..., Sn, Sn = l / (n + 1) (D0 + D1 + ... + Dn) is obtained from the previous data. Each time a sound intensity is detected, the difference between the current intensity and the average intensity is obtained by comparing with the average intensity E0, ΕΙ, . , ., Εη, Εη = Dn - S(n-1). These differences are the sound processing values of the sound signal.

Step 207: The sound processing module 32 determines whether the sound processing value is in the reminder range indicated by the reminding condition, and the sound processing value is greater than the frequency difference E. When the sound intensity En is detected, En>E, at this time, does not immediately proceed to step 208, but continues to detect the sound intensity value En+1 at the next time point, En to En+j are greater than E in a certain period of time Then, proceed to step 208. Step 208, the sound processing module 32 generates a reminder trigger signal for reminding the user, and sends the reminder trigger signal to the CPU module 33. The CPU module 33 reminds the user by using the preset smart voice reminding method according to the stored reminding mode information, the mobile terminal The display shows "Please note that there is an abnormality around the interface. User Li Si can detect changes in ambient sounds while playing games with headphones.

Scene 3, can also see Figure 2 and Figure 3, 4叚, user Xiaowang can't listen well, wear headphones to use the mobile terminal to play games, user Xiaowang wants to know the sound of the surrounding environment at any time, Xiao Wang Set to the mobile terminal to display the volume of the surrounding environment in real time. Step 201: The setting module 34 of the mobile terminal acquires user setting information, and the user Xiao Wang sets the reminding condition and the reminding mode to display the volume level of any sound in the external environment on the display screen in real time. Further, the accuracy information set by the user Xiao Wang is 0.1 ms, and then 0.1 ms is stored as the accuracy information in the CPU module 33. Step 202: The sound signal collecting module 31 collects the sound signal of the external environment in real time, and the signal collecting module 31 records the external data to obtain a real-time recording segment, and stores the recorded segment in the CPU module 33. Step 203, the sound processing module 32 acquires a processing command in the CPU module 33, and the CPU module 33 reads the reminding condition information preset by the user for all the sound signals to be reminded, and the reminding range indicated by the reminding condition is all sound processing values. Step 204, the sound processing module 32 sets a timer according to the detection interval of 0.1 ms; Step 205, detecting the current sound signal from the collected data every time the timer expires; Step 206, the sound processing module 32 processes the detected sound The volume level DO of the signal, and record this data, the next time the timer expires, the data D1 is obtained again, and so on, the sound signal volume intensity data D0, Dl, ..., Dn can be obtained for a period of time. Step 207: The sound processing module 32 determines whether the sound processing value is in the reminder range indicated by the reminding condition, and all the sound processing values are within the reminding range, and proceeds to step 206. Step 208, the sound processing module 32 generates a reminder trigger signal for reminding the user, and sends a reminder trigger signal to the CPU module 33. The CPU module 33 uses the preset real-time display sound volume level to set the sound processing value detected at each time point. Dn is displayed on the display. It should be noted that the present invention can also be applied to other various scenarios, for example: for a hospital treatment system, when a patient is called for help, yelling, and shouting loudly, the physician is reminded to rush to the scene for treatment. It can also be used in early childhood education systems. For example, when it is detected that a child is being crying, the teacher is reminded to know the situation in time to avoid accidents. It is also possible to use a device that generates a reminder function for external sounds on all devices that use headphones or hearing impaired persons. I will not repeat them here. In this embodiment, the mobile terminal processes the sound signal according to the processing command by collecting the sound signal of the external environment in real time, and obtains a sound processing value indicating the sound signal, at the sound. When the value of the reminder indicates the reminder range, the user is reminded by the preset reminder method to realize the function of automatically reminding the user of the ambient sound information when the sound of the earphone is greatly restricted by the earphone, so that the user Correctly handle the sounds around you and avoid missing important or urgent things.
