detailed description

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

In some processes described in the specification and claims of the present invention and the above-mentioned drawings, a plurality of operations appearing in a specific order are contained, but it should be clearly understood that these operations may not be performed in the order in which they appear herein Execution or parallel execution, the serial numbers of the operations, such as 101, 102, etc., are only used to distinguish different operations, and the serial numbers themselves do not represent any execution order. Additionally, these processes can include more or fewer operations, and these operations can be performed sequentially or in parallel. It should be noted that the descriptions of "first" and "second" in this article are used to distinguish different messages, devices, modules, etc. are different types.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

A recording method in a locked screen state, the method is applied to a mobile terminal, the mobile terminal is preset with function keys, and the mobile terminal has a display screen and a microphone, the display screen is used to provide a display interface, and the microphone is used to for ambient sound. As shown in Figure 1, it includes the following steps:

S101: In a locked screen state, receive a first operation instruction performed by a user on a preset function key.

By monitoring the working state of the display screen, it is determined whether the mobile phone is in a locked screen state. If it is in the lock screen state, receive the user's operation instruction. Wherein, the lock screen state is a protection state when the mobile phone is not working. In the locked screen state, the mobile phone can be in the on-screen or off-screen state. When the mobile phone is on the screen, the mobile phone displays the lock screen interface in the locked screen state.

The preset function key is a new physical key set on the mobile terminal, which is different from traditional physical keys such as the volume adjustment key and the screen lock key on the mobile terminal. The mobile terminal runs a background service program with the function key, and the background service program reports the key event of the function key to the system, and the system performs corresponding operations after responding. The function key can be combined with other physical keys or virtual keys on the mobile terminal to form a combination key, and has different functions corresponding to the combination keys formed by different physical keys or virtual keys.

S102: Determine whether the first operation instruction satisfies a first preset condition.

According to different operation instructions of the user, the mobile terminal will implement different functions correspondingly. The operation instruction is restricted, and it is determined whether the operation instruction satisfies the first preset condition. The first preset condition may be that the operation instruction matches the preset instruction data. If the operation instruction matches the preset instruction data, it is determined that it satisfies the first preset condition. If it does not match the preset instruction data , it is determined that it does not meet the first preset condition. Specifically, the first preset condition may define that the first operation instruction is a press operation, a long press operation or a double-click operation.

S103: If the first preset condition is met, start recording.

If the first operation instruction satisfies the first preset condition, call the preset recording application program, send a control instruction to the microphone, drive the microphone to work, and start recording. When the microphone is working, it acquires the surrounding ambient sound and converts the ambient sound into an electrical signal. The electrical signal will be amplified, filtered and transcoded, and finally buffered to the preset memory.

Wherein, the recording application program is a system default recording application or a user-defined recording application. Generally speaking, the operating system is pre-installed with a default recording application, and when there is no other recording application, the default recording application is directly opened. When multiple recording applications are installed in the mobile terminal, the user can set the recording application to be opened when the preset condition is met. For example, the recording applications installed in the mobile terminal are detected, and the user's selection of one of the recording applications is accepted, so that the selected recording application is started when the user's operation instructions on the function keys meet the preset conditions.

S104: If the first preset condition is not satisfied, do not start recording.

In one example, the user attends an important meeting and needs to record the speech at the meeting immediately. At this time, the user can take out the mobile phone and press the function button on the mobile phone. The mobile phone determines that the user's operation command for the function button meets the first preset condition, and immediately starts recording to meet the user's timeliness needs. The recording method is more convenient. Improved user experience.

If the first preset condition is only a single press operation by the user on the function key, it is easy to cause misoperation under the action of external force. For example, the mobile phone is placed in the trouser pocket, and a function button is pressed due to vibration. In the case of misoperation, the recording will also be turned on, which brings inconvenience to the user. Therefore, it is necessary to make appropriate improvements to prevent user misoperations.

In one embodiment, step S102 determines whether the first operation instruction satisfies the first preset condition, specifically: determining whether the first operation instruction is a long-press operation, and if it is a long-press operation, determine whether the first operation instruction satisfies the first preset condition. preset conditions.

When the user presses the function button, the underlying driver of the function button will detect the current jump caused by the press. If the duration of the state after the current jump reaches the predetermined time, it is determined that the user's operation this time is a long press operation. Corresponding to a long press event. Only when the operation command implemented by the user is a long press operation, the recording is started according to the long press event. If the operation command implemented by the user is not a long press operation, the recording is not started.

Wherein, the aforementioned predetermined time may be 300 ms, and of course, those skilled in the art may make appropriate adjustments to the predetermined time in combination with actual conditions. Since the long-press operation requires the user to continuously press the function button instead of a single touch, this greatly reduces the possibility of user misoperation.

In one embodiment, the step of determining whether the first operation instruction satisfies the first preset condition in step S102 is specifically: determining whether the first operation instruction is a double-click operation, and if it is a double-click operation, determining whether the first operation instruction satisfies the first preset condition. preset conditions.

When the user presses the function button, the underlying driver of the function button will detect the current jump caused by the press. If the current jumps twice within the predetermined time, it is determined that the user's current operation is a double-click operation, which corresponds to a double-click event. Only when the operation command implemented by the user is a double-click operation, the recording is started according to the double-click event. If the operation command implemented by the user is not a double-click operation, the recording is not started.

Since the double-click operation requires the user to press the function button twice within a predetermined time instead of a single touch, this also reduces the possibility of user misoperation.

Of course, it can also be set that the recording is enabled only when the user's first operation instruction for the combination of keys is valid, that is, only when the user's first operation instruction for the combination of keys satisfies the first preset condition. The aforementioned combined keys are a combination of preset function keys and at least one physical key and/or at least one virtual key. Therefore, the combined key may be a combination of a preset function key and at least one physical key, for example, a combination of a preset function key and a volume adjustment key. The combined key may also be a combination of a preset function key and at least one virtual key, for example, a combination of a preset function key and a screen lock key. The combined key may also be a combination of a preset function key, a physical key and a virtual key, for example, a combination of a preset function key, a screen lock key and a return key. Certainly, the specific key combination of the combined key may be the default of the mobile terminal or customized by the user. When the user customizes the settings, the mobile terminal must provide a corresponding setting menu for the user to set.

Since the combination key is a combination of multiple keys, the user's double-click operation or long-press operation on the combination key needs to be implemented synchronously. To this end, the pressing time of each key in the combined key is obtained, and when the interval between the first pressed key and the last pressed key is less than a predetermined time, it is determined that the multiple keys are pressed simultaneously. Based on this, simultaneous double-click operations or long-press operations for multiple key combinations can be recognized.

In order to facilitate the user's operation, in view of the fact that the execution of the long press operation is more convenient, for the combination key, the first preset condition is set to be that the first operation instruction is the user's combined long press operation on the combination key. Alternatively, perform a long-press or double-tap operation on only one of the multiple keys, and perform a tap operation on the other keys. Of course, the above are only several preferred examples, and the operation instruction for the combined key may be any one or a combination of double-click operation, long-press operation and other operations.

In order to further reduce user misoperation. In one embodiment, step S101, after receiving the user's first operation instruction on the preset function keys in the locked screen state, further includes the following steps: acquiring the light from the optical sensor that represents the environment where the machine is located Intensity of light intensity data, determine whether the light intensity data matches the preset light intensity comparison data; Match the data and start recording.

A light intensity sensor is provided on the mobile terminal, specifically, it may be provided on the casing of the mobile terminal. The optical sensor is used to detect the light intensity of the environment where the mobile terminal is located. When the user puts the mobile terminal in a pocket of clothes or in a backpack, the light intensity in the environment where the mobile terminal is located is relatively weak. The optical sensor detects the light intensity of the surrounding environment, correspondingly generates light intensity data representing the light intensity, and compares the light intensity data with preset light intensity comparison data. Specifically, the light intensity data includes a light intensity parameter representing the light intensity, and compares whether the light intensity parameter of the light intensity data is greater than the light intensity parameter of the preset light intensity comparison data, and if it is greater, it is determined that the mobile terminal is not placed in the Clothes pocket or backpack, but in use.

Correspondingly, if the first operation command satisfies the first preset condition and the light intensity data matches the preset light intensity comparison data, it is determined that it is not a misoperation by the user, and the recording is started.

In one embodiment, step S101, after receiving the user's first operation instruction on the preset function keys in the locked screen state, further includes the following steps: acquiring the distance sensor indicating that the machine moves within a predetermined time The distance data of the distance is used to determine whether the distance data matches the preset distance comparison data; correspondingly, if the operation command satisfies the preset condition and the distance data matches the preset distance comparison data, the recording is started.

A distance sensor is integrated in the mobile terminal. When the mobile terminal is in a moving state, for example, when the user puts the mobile terminal in a pocket or backpack and walks with the mobile terminal, the distance sensor moves with the movement of the mobile terminal, thereby generating a corresponding The distance data representing the moving distance of the mobile terminal is compared with the preset distance comparison data. Specifically, the distance data includes a distance parameter, and it is judged whether the distance parameter of the distance data is smaller than the distance parameter of the distance comparison data within a predetermined time period, and if it is smaller than the distance parameter of the distance comparison data, it is determined that the mobile terminal is not in a moving state. May be in use by a user.

Correspondingly, if the operation instruction satisfies the preset condition and the distance data matches the preset distance comparison data, it is determined that the user implemented the operation instruction in the use state instead of a wrong operation, and then starts the recording.

In one embodiment, step S101 further includes the following step after the step of receiving the user's first operation instruction on the preset function key in the lock screen state: acquiring the pressure of the pressure sensor representing the pressure on the function key The pressure data is determined to determine whether the pressure data matches the preset pressure comparison data; correspondingly, if the preset condition is met and the pressure data matches the preset pressure comparison data, the recording is started.

A pressure sensor is arranged on or below the function key, and the pressure sensor is used to detect the pressure on the function key. When the user presses the function button, the pressure on the function button increases, and the pressure sensor generates corresponding pressure data representing the pressure on the function button, and compares the pressure data with the preset pressure comparison data. Specifically, the pressure data includes a pressure parameter, and it is judged whether the pressure parameter of the pressure data is greater than the pressure parameter of the pressure comparison data, and if it is greater than the pressure parameter of the pressure comparison data, it is determined that the function button is pressed. The pressure data also includes the duration of pressure applied to the function key. If the pressure parameter of the pressure data is always within a certain predetermined value range within the predetermined time, it is determined that the operation applied to the function key is a long press operation. If it is detected that the pressure parameter jumps twice within a predetermined time, it is determined that the operation applied to the function key is a double-click operation.

Correspondingly, if the first operation instruction satisfies the first preset condition and the pressure data matches the preset pressure comparison data, it is determined that the operation instruction implemented by the user is not a wrong operation, and the recording is started.

On the basis of the foregoing embodiments, as shown in FIG. 2, after step S103, the following steps are also included:

S105: Receive a second operation instruction performed by the user on the preset function key;

S106: Determine whether the operation instruction satisfies a second preset condition;

S107: If the second preset condition is met, end the recording and save the recorded audio file;

S108: If the second preset condition is not met, keep the current recording.

The second preset condition is the user's single press operation, long press operation or double-click operation on the function key. When the user presses the function key, the underlying driver of the function key will detect the current jump caused by the pressing. If there is a current jump, it is determined that the user's current operation is a single pressing operation. If the current jumps twice within the predetermined time, it is determined that the user's current operation is a double-click operation, and a double-click event is correspondingly generated. If the time after the current jump continues for a predetermined time, it is determined that the user's current operation is a long press operation. The system can default the second preset condition to be the user's single press operation, long press operation or double-click operation on the function button. Of course, the second preset condition can also be set by the user. Only when the second operation instruction implemented by the user satisfies the second preset condition, the recording is ended and the recorded audio file is saved.

Of course, in order to prevent the user from misoperation of the function keys. Step S105, after receiving the user's second operation instruction on the preset function key, further includes the following steps: acquiring pressure data of the pressure sensor representing the pressure on the function key, and determining whether the pressure data is consistent with the preset function key. The pressure is matched with the data; if the second preset condition is met in step S107, the recording is ended and the recorded audio file is saved, including: if the second operation command meets the second preset condition and the pressure The data is matched with the preset pressure comparison data, the recording is ended and the recorded audio file is saved.

Alternatively, after step S105 receives the user's second operation instruction on the preset function key, it also includes the following steps: acquiring the light intensity data of the optical sensor representing the light intensity of the environment where the machine is located, and determining the light intensity Whether the data matches the preset light intensity comparison data; step S107, if the second preset condition is met, end the recording and save the recorded audio file, including: if the second operation instruction meets the preset condition and the The light intensity data matches the preset light intensity comparison data, ends the recording and saves the recorded audio file.

Step S105, after receiving the user's second operation instruction on the preset function key, further includes the following steps: acquiring distance data from the distance sensor that represents the moving distance of the machine within a predetermined time, and determining whether the distance data is consistent with the preset function key. The preset distance comparison data match; step S107, if the second preset condition is met, end the recording and save the recorded audio file, including: if the second operation instruction meets the preset condition and the The distance data is matched with the preset distance comparison data, the recording is ended and the recorded audio file is saved.

In one embodiment, the above-mentioned lock screen state includes a security lock screen state that requires a password to be unlocked and a common lock screen state that does not require a password to be unlocked. In the normal lock screen state, the mobile terminal displays a sliding unlock interface or a standby interface, and the user can perform a sliding operation along a preset path to unlock the normal lock screen state. In the security lock screen state, the mobile terminal displays a password unlock interface, such as a Jiugongge password or a digital password. In this password unlock interface, the user needs to enter a preset password. After the verification is passed, the security lock screen state can be unlocked. . Therefore, the security lock screen state is more secure than the common lock screen state, and it is easier to unlock the common lock screen state.

Further, if the second preset condition is met in step S107, the step of ending the recording and saving the recorded audio file includes: if the second preset condition is met, identifying the type of the lock screen state, if it is a security lock screen state, end the recording and save the recorded audio file to the preset safe storage directory, if it is in the normal lock screen state, end the recording and save the recorded audio file to the default audio storage directory; the security The storage directory accepts the user's access only after the password verification is passed.

If the second operation instruction satisfies the second preset condition, monitor the display screen to identify the type of the lock screen state, and determine whether it is a security lock screen state or a common lock screen state. If it is in a secure lock screen state, due to the existence of a password, the recorded audio file is saved to a preset safe storage directory for the purpose of protecting user privacy. When the user accesses the safe storage directory, a password is required. After the password verification is passed, the user can access the safe storage directory to play or delete the recorded file. If it is in a normal lock screen state, a password is not required, and the lock screen state is unlocked directly, and the recorded audio files are saved to the default audio storage directory, and the user does not need a password to access.

Based on the above-mentioned embodiments, the mobile terminal obtains the running status of the recording application, and if the recording application is not enabled for recording, it determines whether the first operation command executed by the user on the function key satisfies the first preset condition, and if so, enables the recording. If the recording application is recording, it is determined whether the second operation command executed by the user on the function key satisfies the second preset condition, and if so, the current recording is ended, and the recorded audio file is saved to a preset storage directory.

In one embodiment, as shown in FIG. 3 , after step S103 , step S109 is further included: after the recording lasts for a predetermined time, end the recording and save the recorded audio file.

In some cases, it is inconvenient for the user to operate the mobile terminal to end the recording. To this end, the duration of the recording is detected, and after the recording lasts for a predetermined time, the recording is automatically ended and the recorded audio file is saved. Further, after the recording lasts for a predetermined time, it is detected whether the microphone acquires a sound signal within a certain period of time, if no sound signal is acquired, the recording is automatically ended and the recorded audio file is saved. Therefore, in this embodiment, the recording can be ended and the recorded file can be saved without the user performing any operation, so as to deal with the situation that the user is inconvenient to operate.

On the basis of the above embodiments, as shown in FIG. 4 , a step S110 is further included: sending the recorded audio file to a preset server. Alternatively, as shown in FIG. 5 , step S111 is further included: sending the recorded audio file to a preset contact through a preset social application.

The mobile terminal is pre-installed with a client program, and the user uses a relevant account to log in to the client program. After the recording is finished, the recorded audio file is sent to the preset server connected to the client through the client program. Alternatively, the user uses a relevant account to pre-log in to a preset social application. After the recording is finished, call the social application, find a preset contact in the contact list of the social application, and send the recorded audio file to the contact through the social application.

In this embodiment, the recorded files are saved as much as possible by uploading the recorded files to the server or sending them to others. Even if the mobile terminal is lost or damaged, the recorded audio files can be retained.

In another embodiment, after step S107, as shown in FIG. 6 , step S110 is further included: sending the recorded audio file to a preset server. Alternatively, as shown in FIG. 7 , step S111 is further included: sending the recorded audio file to a preset contact through a preset social application.

The mobile terminal is pre-installed with a client program, and the user uses a relevant account to log in to the client program. After the user actively ends the recording, the recorded audio file is sent to the preset server connected to the client through the client program. Alternatively, the user uses a relevant account to pre-log in to a preset social application. After the user actively ends the recording, the social application is invoked, a preset contact is found in the contact list of the social application, and the recorded audio file is sent to the contact through the social application.

In one embodiment, the above-mentioned lock screen state includes a security lock screen state that requires a password to be unlocked and a common lock screen state that does not require a password to be unlocked.

In the normal lock screen state, the mobile terminal displays a sliding unlock interface or a standby interface, and the user can perform a sliding operation along a preset path to unlock the normal lock screen state. In the security lock screen state, the mobile terminal displays a password unlock interface, such as a Jiugongge password or a digital password. In this password unlock interface, the user needs to enter a preset password. After the verification is passed, the security lock screen state can be unlocked. . Therefore, the security lock screen state is more secure than the common lock screen state, and it is easier to unlock the common lock screen state.

On this basis, if the first preset condition is met in step S103, the step of starting the recording is specifically: if the first preset condition is met, identify the type of the lock screen state, if it is a security lock screen state, start the recording, If it is in a common screen lock state, cancel the normal lock screen state and start recording.

If the operation instruction satisfies the first preset condition, monitor the display screen to identify the type of the lock screen state, and determine whether it is a security lock screen state or a common lock screen state. If it is in the secure lock screen state, due to the existence of a password, for the sake of protecting user privacy, only the recording application is opened and the recording is turned on, but the current secure screen lock state is not released.
