A method for controlling sound includes：
calling， by a smart terminal， a first sound controlling interface when detecting a system tone playing instruction；
transmitting， by the smart terminal， a first global notification to a three-party application being performing a recording operation via a pre-inputted dynamic library so that the three-party application stops the recording operation when receiving the first global notification， wherein the dynamic library is associated with the first sound controlling interface through a hooking operation；
playing， by the smart terminal， a system tone.
Another method for controlling sound includes：
calling a first sound controlling interface when a system tone playing instruction is detected；
notifying a three-party application being performing a recording operation to stop the recording operation via a pre-inputted dynamic library， wherein the dynamic library is associated with the first sound controlling interface through a hooking operation；

A smart terminal for controlling sound includes：
an interface calling module， to call a first sound controlling interface when a system tone playing instruction is detected；
a notification module， to notify a three-party application being performing a recording operation to stop the recording operation via a pre-inputted dynamic library， wherein the dynamic library is associated with the first sound controlling interface through a hooking operation；
an operation module， to play a system tone when detecting that the three-party application stops the recording operation.
According the technical solution above， when detecting a system tone playing instruction， the first sound control interface is called， and the first global notification is transmitted through a pre-inputted dynamic library. When receiving the first global notification， the third-party application being performing the recording operation stops the recording operation. The smart terminal normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that a process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application which has previously stopped the recording operation receives the second global notification， the recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.

Detailed Description of the Invention
In order to make the object， technical solution and merits of the present invention clearer， the present invention will be illustrated in detail hereinafter with reference to the accompanying drawings and specific embodiments. It should be noted that， the embodiments described herein is to understand the present invention. The present invention cannot be limited to the embodiments.
In an example， an APP may be third-party application program. When a hooking operation is performed for a designated system event and a hooked event occurs， program hooking the event may receive a system notification so that the program responds the hooked event in time.
FIG. 1 is a flowchart illustrating a method for controlling sound in a smart phone according to an embodiment of the present invention. The method includes procedures as follows.
At block S101， when detecting a system tone playing instruction， a smart terminal calls a first sound controlling interface， and transmits a first global notification through a pre-inputted dynamic library.
In an example， the smart terminal may be a mobile terminal such as a smart phone， a tablet computer. An operating system includes， but not limited to， an iOS system， an Android system， a Windows Mobile (WM) system etc. The iOS system is taken as an example in the embodiment.
In the current smart terminal system， a system recording function of a three-party application running on the smart terminal cannot be compatible with an operation of playing a system prompt tone. Thus， when a user uses the recording function， a system cannot play the system prompt tone (e.g.， a short message tone and a push tone of an APP) ， and user experience becomes bad.
In order to implement playing a system prompt tone in a recording process in a smart terminal， a dynamic library is per-generated. Logic codes related with the dynamic library is inputted into a desktop management process SpringBoard of a system process.
Two hooked sound controlling interfaces compatible with a system tone are configured in the system， i.e.， a first sound controlling interface and a second sound controlling interface. In the embodiment， two interfaces (BOOL) _play System Sound： (id) argl and (void) _sound Did Finish Playing： (id) argl of a class SB Sound Controller are taken as an example. Another hooked interface that is compatible with the system tone may be adopted， which is not limited.
The two sound controlling hook interfaces are respectively hooked with the pre-inputted dynamic library.
When detecting that the system is going to play the system tone， the smart terminal calls the first sound controlling interface. A global notification (i.e.， the first global notification in the embodiment) is transmitted from the inputted dynamic library to notify the third-party application being performing the recording operation that there is a prompt tone to be played.
At block S102， after the first global notification is received by the third-party application being performing the recording operation， the recording operation is stopped.
At block S103， the smart terminal plays the system tone.
The application being performing the recording operation may receive the first global notification. After the first global notification is received by the application being performing the recording operation， the recording operation is stopped. The system tone may be normally played.
After a process of playing the system tone finishes， according to a requirement or selection of the user， the APP is notified or is not notified that the process of playing the system tone finishes.
In the technical solution according to the embodiment of the present invention， when detecting a system tone playing instruction， the first sound control interface is called， and the first global notification is transmitted through a pre-inputted dynamic  library. When the first global notification is received by the third-party application being performing the recording operation， the recording operation is stopped， and the smart phone plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. And user requirement is satisfied.
As shown in FIG. 2， a method for control sound is provided according to an embodiment of the present invention， which applies to a system side. On basis of the embodiment as shown in FIG. 1， after performing a procedure at block S103， the method may further include procedures as follows.
At block S 104， when detecting that a process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library.
At block S 105， after the third-party application stopping the recording operation receives the second global notification， the recording operation is continued.
The difference from the embodiment as shown in FIG. 1 is in that the method as shown in FIG. 2 further includes a technical solution of indicating that the third-party application continues to perform the recording operation.
In particular， after the process of playing the system tone finishes， the system may calls the second sound controlling interface. The dynamic library transmits another global notification (i.e.， the second global notification in the embodiment) to notify the APP that has previously stopped the recording operation. After receiving the second notification， the APP re-starts the recording operation to ensure that the recording operation is continued at the background.
According the technical solution above， when detecting a system tone playing instruction， the first sound control interface is called， and the first global notification is transmitted through a pre-inputted dynamic library. When receiving the first global notification， the third-party application being performing the recording operation stops the recording operation. The smart terminal normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that a process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application which has previously stopped the recording operation receives the second global notification， the  recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.
As shown in FIG. 3， a method for control a sound is provided according to an embodiment of the present invention， which applies to a system side. On basis of the embodiment as shown in FIG. 2， before performing a procedure at block S 101， the method may further include procedures as follows.
At block 100， logic codes of the pre-generated dynamic library are inputted into a system running on the smart terminal to hook the first sound control interface and the second control interface pre-configured in the system.
The difference from the embodiment as shown in FIG. 2 is in that the method according to the embodiment of the present invention as shown in FIG. 3 further includes a technical solution of adding the pre-generated dynamic library into the system running on the smart terminal.
In an example， the iOS system is taken as an example. The logic codes of the pre-generated dynamic library are inputted into the desktop management process SpringBoard of the system process.
Two hooked sound controlling interfaces compatible with the system tone are configured in the system， i.e.， the first sound controlling interface and the second sound controlling interface. In the embodiment， the two interfaces (BOOL) _play System Sound： (id) argl and (void) _sound Did Finish Playing： (id) argl of the class SBSound Controller are taken as an example. Another hook interface compatible with the system tone may be adopted， which is not limited.
The two sound controlling interfaces are hooked through the inputted dynamic library. Thus， when the system tone is to be played in the system， the first sound controlling interface is called， and the third-party application being performing the recording operation is notified to stop the recording operation through the inputted dynamic library. After the process of playing the system tone finishes， the second sound controlling interface is called， and the third-party application is notified to continue the recording operation through the inputted dynamic library. Thus， the problem that the system tone cannot be played in the recording process， and user requirements are satisfied.
As shown in FIG. 4， a method for controlling sound is provided according to an embodiment of the present invention， which applies to a system side. On basis of the embodiment as shown in FIG. 3， before performing the procedure at block S 100， the method may further include procedures as follows.
At block S90， the dynamic library is generated.
The difference from the embodiment as shown in FIG. 3 is in that the method according to the embodiment of the present invention as shown in FIG. 4 further includes a technical solution of generating the dynamic library. The dynamic library is used to hook the two sound controlling interfaces that are configured by the system and are compatible with the system tone after the dynamic library is inputted into the smart terminal system and to notify the third-party application to stop or continue the recording operation when the system calls at least one of the two sound controlling interfaces.
According the technical solution above， the dynamic library is generated. The generated dynamic library is inputted into the smart terminal system. When detecting the system tone playing instruction， the first sound control interface is called. The first global notification is transmitted through the pre-inputted dynamic library. When receiving the first global notification， the third-party application being performing the recording operation stops the recording operation. The smart terminal normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that the process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application which has previously stopped the recording operation receives the second global notification， the recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.
As shown in FIG. 5， a method for controlling sound is provided according to an embodiment of the present invention， which applies to a smart terminal side. The method may further include procedures as follows.
At block S201， when detecting a system tone playing instruction， a first sound controlling interface is called.
At block S202， a third-party application being performing a recording operation is notified to stop the recording operation through a pre-inputted dynamic library， wherein the dynamic library is associated with the first sound controlling interface by performing a hooking operation.
In an example， the smart terminal may be a mobile terminal such as a smart phone， a tablet computer. An operating system includes， but not limited to， one of an iOS system， an Android system and a Windows Mobile system. The iOS system is taken as an example in the embodiment.
In the current smart terminal system， a system recording function of a three-party application running on the smart terminal cannot be compatible with an operation of playing a system prompt tone. Thus， when a user uses the recording function， a system cannot play the system prompt tone (e.g.， a short message tone and a push tone of an APP) ， and user experience becomes bad.
In order to implement playing a system prompt tone in a recording process in a smart terminal， a dynamic library is per-generated. Logic codes related with the dynamic library is inputted into a desktop management process SpringBoard of a system process.
Two hooked sound controlling interfaces compatible with a system tone are configured in the system， i.e.， a first sound controlling interface and a second sound controlling interface. In the embodiment， two interfaces (BOOL) _play System Sound： (id) argl and (void) _sound Did Finish Playing： (id) argl of a class SB Sound Controller are taken as an example. Another hooked interface that is compatible with the system tone may be adopted， which is not limited.
The two sound controlling hook interfaces are respectively hooked with the pre-inputted dynamic library.
When detecting that the system is to play the system tone， the smart terminal calls the first sound controlling interface. A global notification (i.e.， the first global notification in the embodiment) is transmitted from the inputted dynamic library to notify the third-party application being performing the recording operation that there is a prompt tone to be played.
At block S203， after detecting that the third-application stops the recording operation， the system tone is played.
The application being performing the recording operation may receive the first global notification. After the first global notification is received by the application being performing the recording operation， the recording operation is stopped. Thus， the system tone may be normally played.
After a process of playing the system tone finishes， according to a requirement or selection of the user， the APP is notified or is not notified that the process of playing the system tone finishes.
In the technical solution according to the embodiment of the present invention， when detecting a system tone playing instruction， the first sound control interface is called， and the first global notification is transmitted through a pre-inputted dynamic library. When the first global notification is received by the third-party application being performing the recording operation， the recording operation is stopped， and the smart phone plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. And user requirement is satisfied.
As shown in FIG. 6， a method for control sound is provided according to an embodiment of the present invention， which applies to a smart terminal side. On basis of the embodiment as shown in FIG. 5， after performing a procedure at block S203， the method may further include procedures as follows.
At block S204， when detecting that a process of playing the system tone finishes， the second controlling interface is called.
At block S205， the third-party application that has stopped the recording operation is notified to continue the recording operation through the dynamic library， wherein the dynamic library is associated with the second sound controlling interface by performing the hooking operation.
The difference from the embodiment as shown in FIG. 5 is in that the method according to the embodiment of the present invention as shown in FIG. 6 further includes a technical solution of indicating that the third-party application to continue to perform the recording operation after a process of playing the system tone finishes.
In particular， after the process of playing the system tone finishes， the system may calls the second sound controlling interface. The dynamic library transmits another global notification (i.e.， the second global notification in the embodiment) to notify the APP that has previously stopped the recording operation. After receiving  the second notification， the APP re-starts the recording operation to ensure that the recording operation is continued at the background.
According the technical solution above， when detecting a system tone playing instruction， the first sound control interface is called， and the first global notification is transmitted through a pre-inputted dynamic library. When receiving the first global notification， the third-party application being performing the recording operation stops the recording operation. The smart terminal normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that a process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application which has previously stopped the recording operation receives the second global notification， the recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.
As shown in FIG. 7， a method for controlling sound is provided according to a embodiment of the present invention， which applies to a smart terminal side. On basis of an embodiment as shown in FIG. 6， before performing a procedure at block S201， the method may further include procedures as follows.
At block 200， logic codes of a pre-generated dynamic library is inputted into the system running on the smart terminal to hook and the pre-configured first sound control interface and the pre-configured second control interface in the system.
The difference from the embodiment as shown in FIG. 6 is in that the method according to the embodiment of the present invention as shown in FIG. 7 further includes a technical solution of inputting the pre-generated dynamic library into the system running on the smart terminal.
In an example， the iOS system is taken as an example. The logic codes of the pre-generated dynamic library are inputted into the desktop management process Spring Board of the system process.
Two hooked sound controlling interfaces compatible with the system tone are configured in the system， i.e.， the first sound controlling interface and the second sound controlling interface. In the embodiment， the two interfaces (BOOL) _play System Sound： (id) argl and (void) sound Did Finish Playing： (id) argl of  the class SB Sound Controller are taken as an example. Another hook interface compatible with the system tone may be adopted， which is not limited.
The inputted dynamic library hooks two sound controlling interfaces. Thus， when the system tone is to be played in the system， the first sound controlling interface is called， and the third-party application being performing the recording operation is notified to stop the recording operation through the inputted dynamic library. After the process of playing the system tone finishes， the second sound controlling interface is called， and the third-party application is notified to continue the recording operation through the inputted dynamic library. Thus， the problem that the system tone cannot be played in the recording process， and user requirements are satisfied.
As shown in FIG. 8， a method for controlling a sound is provided according to an embodiment of the present invention， which applies to a smart terminal side. On basis of the embodiment as shown in FIG. 7， before performing the procedure at block 200， the method may further include procedures as follows.
At block S 190， the dynamic library is generated.
The difference from the embodiment as shown in FIG. 7 is in that the method according to the embodiment of the present invention as shown in FIG. 8 further includes a technical solution of generating the dynamic library. The dynamic library is used to hook the two sound controlling interfaces that are configured by the system and are compatible with the system tone after the dynamic library is inputted into the smart terminal system and to notify the third-party application to stop or continue the recording operation when the system calls at least one of the two sound controlling interfaces.
According the technical solution above， the dynamic library is generated. The generated dynamic library is inputted into the smart terminal system. When detecting the system tone playing instruction， the first sound control interface is called. The first global notification is transmitted through the pre-inputted dynamic library. When receiving the first global notification， the third-party application being performing the recording operation stops the recording operation. The smart terminal normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that the process of playing  the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application which has previously stopped the recording operation receives the second global notification， the recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.
FIG. 9 is a schematic diagram illustrating a structure of a system for controlling sound in a smart phone according to an embodiment of the present invention. The system includes a smart terminal 301 and a three-party application 302 running on the smart terminal 301.
The smart phone 301 is to call a first sound controlling interface when detecting a system tone playing instruction， transmit a first global notification via a pre-inputted dynamic library.
The three-party application 302 is to stop a recording operation being performed when receiving the first global notification.
The smart phone 301 is further to play a system tone.
In an example， the smart terminal 301 may be a mobile terminal such as a smart phone， a tablet computer. An operating system includes， but not limited to， one of an iOS system， an Android system and a Windows Mobile system. The iOS system is taken as an example in the embodiment.
In the current system of the smart terminal 301， a system recording function of a three-party application 302 running on the smart terminal 301 cannot be compatible with an operation of playing a system prompt tone. Thus， when a user uses the recording function， a system cannot play the system prompt tone (e.g.， a short message tone and a push tone of an APP) ， and user experience becomes bad.
In order to implement playing a system prompt tone in a recording process in the smart terminal 301， a dynamic library is per-generated. Logic codes related with the dynamic library is inputted into a desktop management process Spring Board of a system process.
Two hooked sound controlling interfaces compatible with a system tone are configured in the system， i.e.， a first sound controlling interface and a second sound  controlling interface. In the embodiment， two interfaces (BOOL) _play System Sound： (id) argl and (void) _sound Did Finish Playing： (id) argl of a class SB Sound Controller are taken as an example. Another hooked interface that is compatible with the system tone may be adopted， which is not limited.
The two sound controlling hook interfaces are respectively hooked with the pre-inputted dynamic library.
When detecting that the system is to play the system tone， the smart terminal 301 calls the first sound controlling interface. A global notification (i.e.， the first global notification in the embodiment) is transmitted from the inputted dynamic library to notify the third-party application 302 being performing the recording operation that there is a prompt tone to be played.
The application being performing the recording operation may receive the first global notification. After the first global notification is received by the application being performing the recording operation， the recording operation is stopped. The system tone may be normally played.
After a process of playing the system tone finishes， according to a requirement or selection of the user， the APP is notified or is not notified that the process of playing the system tone finishes.
In the technical solution according to the embodiment of the present invention， when detecting a system tone playing instruction， the first sound control interface is called， and the first global notification is transmitted through a pre-inputted dynamic library. When the first global notification is received by the third-party application 302 being performing the recording operation， the recording operation is stopped， and the smart phone 301 plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. And user requirement is satisfied.
Furthermore， the smart phone 301 is further to call a second sound controlling interface after detecting that a process of playing the system tone finishes， transmit a second global notification through the dynamic library.
The three-party application 302 is further to continue the recording operation after receiving the second global notification.
In particular， after the process of playing the system tone finishes， the system may calls the second sound controlling interface. The dynamic library transmits another global notification (i.e.， the second global notification in the embodiment) to notify the APP that has previously stopped the recording operation. After receiving the second notification， the APP re-starts the recording operation to ensure that the recording operation is continued at the background.
According the technical solution above， when detecting a system tone playing instruction， the first sound control interface is called， and the first global notification is transmitted through a pre-inputted dynamic library. When receiving the first global notification， the third-party application 302 being performing the recording operation stops the recording operation. The smart terminal 301 normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that a process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application 302 which has previously stopped the recording operation receives the second global notification， the recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.
Furthermore， the smart phone 301 is further to add logic codes of the dynamic library pre-generated into a system of the smart phone 301 to perform the hooking operation between the first sound controlling interface and the dynamic library and between the second sound controlling interface and the dynamic library.
Furthermore， the smart phone 301 is further to generate the dynamic library. The dynamic library is used to hook the two sound controlling interfaces that are configured by the system and are compatible with the system tone after the dynamic library is inputted into the smart terminal system and to notify the third-party application 302 to stop or continue the recording operation when the system calls at least one of the two sound controlling interfaces.
According the technical solution above， the dynamic library is generated. The generated dynamic library is inputted into the smart terminal system. When detecting the system tone playing instruction， the first sound control interface is called. The first global notification is transmitted through the pre-inputted dynamic library. When  receiving the first global notification， the third-party application 302 being performing the recording operation stops the recording operation. The smart terminal 301 normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that the process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application 302 which has previously stopped the recording operation receives the second global notification， the recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.
FIG. 10 is a schematic diagram illustrating a structure of a smart phone for controlling sound in a smart phone according to an embodiment of the present invention. The smart terminal includes an interface calling module 401， a notification module 402， and an operation module 403.
The interface calling module 401 is to call a first sound controlling interface when a system tone playing instruction is detected.
The notification module 402 is to notify a three-party application being performing a recording operation to stop the recording operation via a pre-inputted dynamic library， wherein the dynamic library is associated with the first sound controlling interface through a hooking operation.
The operation module 403 is to play a system tone when detecting that the three-party application stops the recording operation.
In an example， the smart terminal may be a mobile terminal such as a smart phone， a tablet computer. An operating system includes， but not limited to， one of an iOS system， an Android system and a Windows Mobile system. The iOS system is taken as an example in the embodiment.
In the current system of the smart terminal， a system recording function of a three-party application running on the smart terminal cannot be compatible with an operation of playing a system prompt tone. Thus， when a user uses the recording function， a system cannot play the system prompt tone (e.g.， a short message tone and a push tone of an APP) ， and user experience becomes bad.
In order to implement playing a system prompt tone in a recording process in the smart terminal， a dynamic library is per-generated. Logic codes related with the dynamic library is inputted into a desktop management process SpringBoard of a system process.
Two hooked sound controlling interfaces compatible with a system tone are configured in the system， i.e.， a first sound controlling interface and a second sound controlling interface. In the embodiment， two interfaces (BOOL) _play System Sound： (id) argl and (void) _sound Did Finish Playing： (id) argl of a class SB Sound Controller are taken as an example. Another hooked interface that is compatible with the system tone may be adopted， which is not limited.
The two sound controlling hook interfaces are respectively hooked with the pre-inputted dynamic library.
When detecting that the system is to play the system tone， the smart terminal calls the first sound controlling interface. A global notification (i.e.， the first global notification in the embodiment) is transmitted from the inputted dynamic library to notify the third-party application being performing the recording operation that there is a prompt tone to be played.
The application being performing the recording operation may receive the first global notification. After the first global notification is received by the application being performing the recording operation， the recording operation is stopped. The system tone may be normally played.
After a process of playing the system tone finishes， according to a requirement or selection of the user， the APP is notified or is not notified that the process of playing the system tone finishes.

Furthermore， the interface calling module 401 is further to call a second sound controlling interface after detecting that a process of playing the system tone finishes.
The notification module 402 is further to notify the three-party application stopping the recording operation to continue the recording operation through the dynamic library， wherein the dynamic library is associated with the second sound controlling interface through the hooking operation.
In particular， after the process of playing the system tone finishes， the system may calls the second sound controlling interface. The dynamic library transmits another global notification (i.e.， the second global notification in the embodiment) to notify the APP that has previously stopped the recording operation. After receiving the second notification， the APP re-starts the recording operation to ensure that the recording operation is continued at the background.

FIG. 11 is a schematic diagram illustrating a structure of a smart phone for controlling sound in a smart phone according to an embodiment of the present invention. Based on the embodiment as shown in FIG. 10， the smart terminal further includes an inputting module 400.
The inputting module 400 to input logic codes of the dynamic library pre-generated into a system of the smart terminal to perform the hooking operation between the first sound controlling interface and the dynamic library and to perform the hooking operation between the second sound controlling interface and the dynamic library.
In an example， the iOS system is taken as an example. The logic codes of the pre-generated dynamic library are inputted into the desktop management process SpringBoard of the system process.
Two hooked sound controlling interfaces compatible with the system tone are configured in the system， i.e.， the first sound controlling interface and the second sound controlling interface. In the embodiment， the two interfaces (BOOL) _play System Sound： (id) argl and (void) _sound Did Finish Playing： (id) argl of the class SB Sound Controller are taken as an example. Another hook interface compatible with the system tone may be adopted， which is not limited.
The two sound controlling interfaces are hooked through the inputted dynamic library. Thus， when the system tone is to be played in the system， the first sound controlling interface is called， and the third-party application being performing the recording operation is notified to stop the recording operation through the inputted dynamic library. After the process of playing the system tone finishes， the second sound controlling interface is called， and the third-party application is notified to continue the recording operation through the inputted dynamic library. Thus， the problem that the system tone cannot be played in the recording process， and user requirements are satisfied.
FIG. 12 is a schematic diagram illustrating a structure of a smart phone for controlling sound in a smart phone according to an embodiment of the present invention. Based on the embodiment as shown in FIG. 11， the smart terminal further includes a generation module 390.
The generation module 390 is to generate the dynamic library.
The difference from the embodiment as shown in FIG. 11 is in that the method according to the embodiment of the present invention as shown in FIG. 12 further includes a technical solution of generating the dynamic library. The dynamic library is used to hook the two sound controlling interfaces that are configured by the system and are compatible with the system tone after the dynamic library is inputted into the smart terminal system and to notify the third-party application to stop or continue the recording operation when the system calls at least one of the two sound controlling interfaces.
According the technical solution above， the dynamic library is generated. The generated dynamic library is inputted into the smart terminal system. When detecting the system tone playing instruction， the first sound control interface is called. The first global notification is transmitted through the pre-inputted dynamic library. When  receiving the first global notification， the third-party application being performing the recording operation stops the recording operation. The smart terminal normally plays the system tone. Thus， it is implemented that the system prompt tone can be normally played in a recording process. Furthermore， when detecting that the process of playing the system tone finishes， the second control interface is called， the second global notification is transmitted through the dynamic library. After the third-party application which has previously stopped the recording operation receives the second global notification， the recording operation is continued. Thus， it is solved that system prompt tone cannot be normally played in a recording process. And user requirement is satisfied.
It should be noted that， the term “includes” means includes but not limited to， the term “including” means including but not limited to. The term “based on” means based at least in part on so that a process， method or device may not only include those elements， but may also include another element that has not be directly listed， or may include elements that is inherently included in the process， method or device. In a condition that there is not more limitation， it is not excluded that in the process， method or device， an element limited by “including a. . . ” may include another same element.
Those skilled in the art can understand that all or part of steps in the method provided by the examples of the present invention can be implemented by instructing related hardware by a program， the program may be stored in a readable memory of a computer， and above method steps are included when the program is operated. The memory includes a ROM/RAM， a disk， a Compact Disc (CD) and so on.
FIG. 13 is a schematic diagram illustrating a structure of an apparatus for controlling sound according to an embodiment of the present invention. As shown in FIG. 13， the apparatus includes a processor 51 for executing instructions stored in a memory 52. The instructions include an interface calling instruction 501， a notification instruction 502， an operation instruction 503.
The interface calling instruction 501 is to call a first sound controlling interface when a system tone playing instruction is detected.
The notification instruction 502 is to notify a three-party application being performing a recording operation to stop the recording operation via a pre-inputted  dynamic library， wherein the dynamic library is associated with the first sound controlling interface through a hooking operation.
The operation instruction 503 is to play a system tone when detecting that the three-party application stops the recording operation.
In an example， the interface calling instruction 501 is further to call a second sound controlling interface after detecting that a process of playing the system tone finishes.
The notification instruction 502 is further to notify the three-party application stopping the recording operation to continue the recording operation through the dynamic library， wherein the dynamic library is associated with the second sound controlling interface through the hooking operation.
In an example， the apparatus further includes an inputting instruction 504. The inputting instruction 504 is to input logic codes of the dynamic library pre-generated into a system of the smart terminal to perform the hooking operation between the first sound controlling interface and the dynamic library and to perform the hooking operation between the second sound controlling interface and the dynamic library.
In an example， the apparatus further includes a generation module instruction 505. The generation instruction 505 is to generate the dynamic library.
The foregoing is only preferred examples of the present invention and is not used to limit the protection scope of the present invention. Any modification， equivalent substitution and improvement without departing from the spirit and principle of the present invention are within the protection scope of the present invention.
