All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 1 is a diagram illustrating an exemplary embodiment of a method for controlling an output vibration signal. As shown in fig. 1, the method of controlling an output vibration signal is applied to a system for controlling an output vibration signal. The system for controlling the output of the vibration signal comprises a terminal 1, wherein the terminal 1 can be a desktop terminal or a mobile terminal, and the mobile terminal can be at least one of a mobile phone, a tablet computer, a notebook computer and the like. The terminal comprises a media service module 11, a media driving service module 12, a motor driving service module 13, a media playing terminal 14 and a motor playing terminal 15. The media service module 11 is used to control the synchronous playing of the media file and the motor vibration. The media driving service module 12 obtains the media playing instruction sent by the media service module 11, and drives the media file to be played at the media playing terminal 14 according to the media playing instruction. The motor driving service module 13 obtains the target vibration signal identifier sent by the media service module 11, and drives the motor playing terminal 15 to vibrate according to the target vibration signal identifier.
In one embodiment, as shown in FIG. 2, a method of controlling an output vibration signal is provided. The method can be applied to a terminal, a server and other devices for controlling and outputting the vibration signals. The present embodiment is exemplified by an apparatus applied to control an output vibration signal. And the media service module in the device for controlling the output of the vibration signal determines a target vibration signal identifier through the current playing time of the target media file and the vibration information table based on the same timer, and sends the target vibration signal identifier to the motor driving service, so that the motor driving service drives the motor according to the target vibration signal identifier, and the synchronous playing of the target media file and the motor vibration is realized. The method for controlling the output vibration signal specifically comprises the following steps:
step 102: the media service acquires a vibration information table, wherein the vibration information table records a plurality of vibration point information, and each vibration point information comprises a vibration starting time and a vibration signal identification.
The media service refers to a control module capable of playing media files and motor vibration synchronously, wherein the media files include but are not limited to audio files and video files.
Wherein the vibration information table refers to a vibration information configuration table including a plurality of vibration point information stored in advance in the media service. The vibration point information corresponds to the vibration information of each vibration of the motor one by one, and the vibration point information comprises vibration starting time and vibration signal identification.
The vibration signal identification is used for uniquely identifying one vibration signal. The vibration signal identifier may be the storage location information of the vibration signal, or a number corresponding to the storage location information of the vibration signal one to one, and may also be determined according to other unique characteristics of the vibration signal.
Step 104: the media service comprises a timer, the media service sends a playing instruction to the media driving service so that the media driving service can play the target media file conveniently, and the timer starts to time.
The media driving service is used for receiving the playing instruction sent by the media service and driving the corresponding media file to play according to the playing instruction.
The target media file refers to a media file which is required to be played by an operator in synchronization with the vibration of the motor.
The timer is a tool for recording the playing time of the medium.
And when the media service sends a playing instruction to the media driving service, starting timing by a timer, wherein the time recorded in the timer is the playing time of the target media file.
Step 106: and the media service obtains the current playing time of the target media file through the timer, and determines a target vibration signal identifier according to the current playing time and the vibration information table.
The current playing time of the target media file refers to the time of the target media file in the current playing progress, and can be obtained according to the time data recorded by the timer.
The target vibration signal identification is determined according to the current playing time and the vibration starting time of a plurality of vibration points in the vibration information table. And if the current playing time is not the same as or not similar to the vibration starting time of any vibration point in the vibration information table, the target vibration signal is marked to be empty, namely the target vibration signal does not contain any content. And if the target vibration signal identification is empty, the motor driving service does not drive the motor to vibrate after acquiring the target vibration signal identification, and waits for the media service to acquire the current playing time of the target media file again.
Step 108: the media service sends the target vibration signal identification to a motor driving service so that the motor driving service drives a motor according to the target vibration signal identification.
The motor driving service refers to a module for driving the motor to vibrate. The motor driving service receives a target vibration signal identifier sent by the media service, acquires a target vibration signal according to the target vibration signal identifier, and drives the motor to vibrate according to the target vibration signal.
The method for controlling the output of the vibration signal obtains the vibration information table through the media service, obtains the current playing time of the target media file according to a timer in the media service, determines the target vibration signal identification according to the current playing time of the target file and the vibration information table, and drives the motor according to the target vibration signal identification by the motor driving service. Because the playing of the media file and the driving of the motor are controlled based on the same timer, the media file and the motor can be synchronously played in a vibrating way according to the time of the timer read every time, the running procedure is simple, and the time error caused by setting two different timers can not occur, so that the problem that the playing of the media file and the motor is not synchronous or vibration leakage occurs due to the time error can be avoided, and the synchronous playing of the media file and the motor vibration can be effectively realized.
In one embodiment, the step 106 of obtaining the current playing time of the target media file through the timer includes:
step 106A: and acquiring a time reading instruction sent by the media drive service.
The time reading instruction is used for reading the timing time of the timer.
The media driving service communicates with the media service according to preset conditions, and in the communication process, the media driving service sends a time reading instruction to the media service to acquire the current playing time of the target media file. The preset condition may be a preset time period, for example, the media drive service 1s communicates with the media service once, and the media service 1s receives a time reading instruction sent by the media drive service once.
Step 106B: and acquiring the timing time of the timer according to the time reading instruction.
And the media service reads the current recording time of the timer according to the received time reading instruction, so that the timing time of the timer can be acquired.
Step 106C: and taking the timing time as the current playing time of the target media file.
And the media service reads the timing time of the timer at the moment according to the time reading instruction sent by the media drive service. Since the timer records the playing time of the target media file, the read timed time can be used as the playing time of the target media file.
In one embodiment, the obtaining the time reading instruction sent by the media drive service in step 106A includes: and acquiring a time reading instruction sent by the media drive service every preset time.
The media drive service sends a time reading instruction every other preset time, and correspondingly, the media drive service obtains the timing time of the timer according to the obtained time reading instruction every other preset time, so that the current playing time of the target media file can be obtained for the preset time according to the period.
In one embodiment, the step 106 of determining the target vibration signal identifier according to the current playing time and the vibration information table includes:
step 106 a: and comparing the current playing time with the vibration starting time of the plurality of vibration point information in the vibration information table to obtain target vibration point information.
The target vibration point information is determined according to the current playing time and the vibration starting time of the vibration point information in the vibration information table, if the current playing time is the same as or close to the vibration starting time of a certain vibration point information in the vibration information table, the vibration point information is the target vibration point information, and if the vibration starting time of any vibration point information in the vibration information table is different from or not close to the current playing time, the target vibration point information is a null point which does not contain the vibration information.
In one embodiment, step 106a includes:
step 106a 1: a time error range is obtained.
The time error range refers to a range within which the playing of the target media file and the playing of the motor vibration can be considered to be synchronously played.
The following factors are mainly considered for determining the time error range: and the distribution rule of the vibration starting time of the information of the plurality of vibration points in the vibration information table, the frequency of the current playing time and the time loss caused by information transmission between the media service and the media driving service and the motor driving service are obtained. If the vibration starting time distribution of the plurality of vibration point information in the vibration information table is dense, and the frequency of obtaining the current playing time is faster, the time error range is smaller, and the vibration signal identifier for obtaining the same vibration point information for multiple times is avoided being used as a target vibration identifier; if the vibration starting time distribution of the information of the plurality of vibration points in the vibration information table is dispersed and the frequency of the current playing time is acquired slowly, the time error range is set to be larger, and the phenomenon of vibration leakage is avoided. If the time loss caused by information transmission between the media service and the media drive service and the motor drive service is large, the time loss is considered when determining the time error range, and the method is favorable for improving the synchronism of the target media file and the motor vibration playing.
Step 106a 2: and obtaining a confidence interval corresponding to the current playing time according to the current playing time of the target media file and the time error range.
The confidence interval corresponding to the current playing time is that the time falling into the confidence interval can be considered to be the same as or similar to the current playing time. Illustratively, the current playing time is T, the time error range is ± T, and the confidence interval corresponding to the current playing time is (T-T, T + T).
Step 106a 3: and obtaining target vibration point information according to the confidence interval corresponding to the current playing time and the vibration starting time of the vibration point information in the vibration information table.
If the vibration starting time of certain vibration point information in the vibration information table falls into the confidence interval corresponding to the current playing time, the vibration point information is target vibration point information; and if the vibration starting time of any vibration point information in the vibration information table does not fall into the confidence interval corresponding to the current playing time, the target vibration point information is a null point which does not contain the vibration information.
Step 106 b: and taking the vibration signal identification of the target vibration point information as a target vibration signal identification.
If the target vibration point information is certain vibration point information, a vibration signal identifier contained in the vibration point information is used as a target vibration signal identifier; and if the target vibration point information is a null point which does not contain vibration information, marking the target vibration signal as null.
As shown in fig. 3, in an embodiment, the step 106 of determining the target vibration signal identifier according to the current playing time and the vibration information table includes:
the step of arranging according to the time sequence means that the plurality of vibration point information in the vibration information table are arranged according to the sequence of the vibration starting time in the vibration point information. Illustratively, the vibration information table includes three pieces of vibration point information, which are sequentially a (t1, SignalID1), B (t2, SignalID2), and C (t3, SignalID3), where SignalID refers to a vibration signal identifier, t1< t2< t3, and a plurality of pieces of vibration point information in the vibration information table are arranged in chronological order, that is, a (t1, SignalID1), B (t2, SignalID2), and C (t3, SignalID 3).
Step 1061: and comparing the current playing time with the vibration starting time of the first vibration point information in the vibration information table.
The vibration start time of the first vibration point information in the vibration information table is the earliest, and if the current playing time is less than the vibration start time of the vibration point, the current playing time is certainly less than the vibration start time of other vibration point information in the vibration information table. Comparing the current playing time with the vibration starting time of the first vibration point information in the vibration information table every time, namely comparing the current playing time with the vibration starting time of the vibration point information of which the first vibration signal identification in the vibration information table is not acquired by the motor driving service every time until the vibration signal identifications of all the vibration point information in the vibration information table are acquired by the motor driving service.
Step 1062: and if the comparison result is that the absolute value of the difference value between the current playing time and the vibration starting time of the first vibration point information is smaller than a preset value, taking the vibration signal identifier of the first vibration point information as the target vibration signal identifier.
Wherein the predetermined value is the same as the above-mentioned determining factor of the time error range.
An absolute value of a difference △ T between the current playing time T1 and the vibration starting time T2 of the first vibration point is smaller than a preset value, and then an error value between T1 and T2 is smaller than the preset value, T1 and T2 can be regarded as the same time, the vibration signal identifier of the first vibration point information is taken as the target vibration signal identifier, and the motor driving service drives the motor to vibrate according to the target vibration signal identifier and plays the target media file synchronously.
Step 1063: and deleting the first vibration point information in the vibration information table.
And when the vibration signal identification of the first vibration point information in the vibration information table is used as the target vibration signal identification, the motor driving service deletes the first vibration point information from the vibration information table and updates the vibration information table after driving the motor to vibrate according to the target vibration signal identification. In the updated vibration information table, the second-bit vibration point information originally arranged in the vibration information table before updating is arranged at the first bit, and when the media service acquires the current playing time of the target media file again, the media service determines the target vibration signal identifier according to the current playing time of the target media file and the first vibration point information in the updated vibration information table. Therefore, each media service can accurately determine the target vibration signal identifier according to the current playing time of the target media file and the first vibration point information in the current vibration information table, the current playing time is prevented from being compared with the vibration starting time of a plurality of vibration point information in the vibration information table, the running speed is improved, meanwhile, the time error caused by the internal reason of the system can be reduced, and the consistency of synchronous playing of the media file and motor vibration is improved.
In one embodiment, the method further comprises:
step 1064: and if the comparison result is that the absolute value of the difference value between the current playing time and the vibration starting time of the first vibration point information is greater than or equal to a preset value, entering a read waiting state to acquire the timing time of the timer when receiving a time reading instruction sent by the media driving service.
When the absolute value of the difference △ T between the current playing time T1 and the vibration starting time T2 of the first vibration point is greater than or equal to a preset value, the error value between T1 and T2 is greater than or equal to the preset value, and T1 and T2 cannot be regarded as the same time, at this time, the target vibration point information is an empty point which does not include a vibration signal identifier, the target vibration signal identifier is empty, and the motor driving service does not drive the motor to vibrate.
In one embodiment, there is provided an apparatus for controlling an output vibration signal, the apparatus including:
the media service module is used for acquiring a vibration information table, wherein the vibration information table records a plurality of vibration point information, and each vibration point information comprises vibration starting time and a vibration signal identifier;
