The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
FIG. 1 is a diagram of an environment in which a method of controlling an output vibration signal is used in one embodiment. 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 and outputting 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 drive service module 12, a motor drive service module 13, a media playing end 14 and a motor playing end 15. The media service module 11 is used for controlling the synchronous play 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 vibration signals. The present embodiment is exemplified as an apparatus applied to control output vibration signals. The media service module in the device for controlling and outputting the vibration signal determines the target vibration signal identification based on the same timer through the current playing time of the target media file and the vibration information table, and sends the target vibration signal identification to the motor driving service, so that the motor driving service drives the motor according to the target vibration signal identification, and synchronous playing of the target media file and motor vibration is realized. The method for controlling the output vibration signal specifically comprises the following steps:
step 102: the media service obtains a vibration information table that records a plurality of vibration point information, each of which includes a vibration start time and a vibration signal identification.
Wherein, the media service refers to a control module capable of realizing synchronous playing of media files and motor vibration, wherein, the media files comprise but are not limited to audio files and video files.
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 a vibration starting time and a vibration signal mark.
The vibration signal identifier is used for uniquely identifying one vibration signal. The vibration signal identification can be the storage position information of the vibration signal, can be a number corresponding to the storage position information of the vibration signal one by one, and can be determined according to other unique characteristics of the vibration signal.
Step 104: the media service includes a timer that sends a play instruction to the media drive service for the media drive service to play the target media file, the timer starting to count.
The media drive service is used for receiving a 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 that an operator needs to play synchronously with motor vibration.
The timer is means for recording the playing time of the media.
The media service sends playing instructions to the media drive service, and a timer starts to count, and 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 under the current playing progress, and can be obtained according to the time data recorded by the timer.
Wherein 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. If the current playing time is the same as or similar to the vibration starting time of one vibration point in the vibration information table, the target vibration signal is identified as the vibration identification of the vibration point, and if the current playing time is different from or not similar to the vibration starting time of any vibration point in the vibration information table, the target vibration signal is identified as empty, namely the target vibration signal does not contain any content. If the target vibration signal identifier is empty, the motor driving service does not drive the motor to vibrate after acquiring the target vibration signal identifier, 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 drive service so that the motor drive 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 vibration signal obtains the vibration information table through the media service, obtains the current playing time of the target media file according to the 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 by the same timer, the synchronous playing of the media file and the motor vibration can be realized according to the time of the timer read each time, the running program is simple, and the time error caused by setting two different timers can not occur, thereby the problem that the playing of the media file and the motor is asynchronous or the 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 obtaining, in step 106, the current playing time of the target media file by 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.
And the media drive service communicates with the media service according to preset conditions, and in the communication process, the media drive service sends a time reading instruction to the media service so as to acquire the current playing time of the target media file. The preset condition may be a preset time period, and illustratively, the media driving service 1s communicates with the media service once, and the media service 1s receives a time reading instruction sent by the media driving 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 obtained.
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 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 timing 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 driving service in step 106A includes: and acquiring a time reading instruction sent by the media drive service at intervals of preset time.
The media drive service sends a time reading instruction every preset time, and correspondingly, the media service obtains the timing time of the timer according to the obtained time reading instruction every preset time, so that the current playing time of the target media file can be obtained according to the period as the preset time.
In one embodiment, the determining, in step 106, the target vibration signal identifier according to the current playing time and the vibration information table includes:
step 106a: and comparing the current playing time with vibration starting time of a plurality of pieces 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 a plurality of vibration point information in the vibration information table, if the current playing time is the same as or similar to the vibration starting time of one 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 not the same as or similar to the current playing time, the target vibration point information is an empty point which does not contain vibration information.
In one embodiment, step 106a includes:
step 106a1: a time error range is acquired.
Where a time error range refers to a range in which playback of the target media file and playback of the motor vibration can be considered synchronized playback.
The considerations for determining the time error range are mainly the following: and acquiring the frequency of the current playing time and the time loss caused by information transmission among the media service, the media drive service and the motor drive service according to the distribution rule of the vibration starting time of the vibration point information in the vibration information table. If the vibration starting time distribution of the plurality of vibration point information in the vibration information table is dense, and the frequency of acquiring the current playing time is fast, the time error range should be set smaller, so that vibration signal identifiers for acquiring the same vibration point information for multiple times are prevented from being used as target vibration identifiers; if the vibration starting time distribution of the plurality of vibration point information in the vibration information table is dispersed, and the frequency of acquiring the current playing time is slow, the time error range should be set larger, and the phenomenon of vibration leakage is avoided. If the time loss caused by the information transmission between the media service and the media drive service and the motor drive service is large, the time loss should be considered when determining the time error range, which is beneficial to improving the synchronicity of the target media file and the motor vibration playing.
Step 106a2: 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 means that the time falling into the confidence interval can be considered to be the same as or similar to the current playing time. For example, 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 106a3: and obtaining target vibration point information according to the confidence interval corresponding to the current playing time and the vibration starting time of the plurality of vibration point information in the vibration information table.
If the vibration starting time of a 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; 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 vibration information.
Step 106b: 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 a certain vibration point information, the vibration signal identifier contained in the vibration point information is used as a target vibration signal identifier; if the target vibration point information is a null point which does not contain vibration information, the target vibration signal is marked as null.
In one embodiment, as shown in fig. 3, the determining, in step 106, the target vibration signal identifier according to the current playing time and the vibration information table includes:
the arrangement according to the time sequence means that a plurality of vibration point information in the vibration information table is arranged according to the sequence of the vibration starting time in the vibration point information. For example, the vibration information table includes three vibration point information, which are a (t 1, signalID 1), B (t 2, signalID 2), and C (t 3, signalID 3), where SignalID refers to a vibration signal identifier, t1< t2< t3, and the plurality of vibration point information in the vibration information table are obtained by arranging a (t 1, signalID 1), B (t 2, signalID 2), and C (t 3, signalID 3) in time sequence.
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 starting time of the first vibration point information in the vibration information table is earliest, and if the current playing time is smaller than the starting vibration time of the vibration point, the current playing time is necessarily smaller than the vibration starting time of other vibration point information in the vibration information table. Each time the current playing time is compared with the vibration starting time of the first vibration point information in the vibration information table, namely each time the current playing time is compared with the vibration starting time of the vibration point information of which the first vibration signal identification is not acquired by the motor driving service, 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 shows 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, the vibration signal identifier of the first vibration point information is used as the target vibration signal identifier.
Wherein the preset value is the same as the determining factor of the time error range.
And if the absolute value of the difference Deltat between the current playing time T1 and the vibration starting time T2 of the first vibration point is smaller than a preset value, the error value of T1 and T2 is smaller than the preset value, and T1 and T2 can be regarded as the same time, the vibration signal identifier of the first vibration point information is used as the target vibration signal identifier, and the motor driving service drives the motor to vibrate and synchronously play the target media file according to the target vibration signal identifier.
Step 1063: and deleting the first vibration point information in the vibration information table.
When the vibration signal identifier of the first vibration point information in the vibration information table is used as the target vibration signal identifier, the motor driving service drives the motor to vibrate according to the target vibration signal identifier, then the first vibration point information is deleted from the vibration information table, and the vibration information table is updated. In the updated vibration information table, the second vibration point information originally arranged in the vibration information table before updating is arranged at the first position, and when the media service acquires the current playing time of the target media file again, the media service determines the target vibration signal identification according to the current playing time of the target media file and the first vibration point information in the vibration information table after updating. Therefore, each media service can be ensured to accurately determine the target vibration signal identification according to the current playing time of the target media file and the first vibration point information in the current vibration information table, the comparison of the current playing time and the vibration starting time of a plurality of vibration point information in the vibration information table is avoided, the running speed is improved, meanwhile, the time error caused by the internal reasons of the system is reduced, and the synchronous playing consistency of the media file and the 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 larger than or equal to a preset value, entering a waiting time reading state to acquire the timing time of the timer when a time reading instruction sent by the media drive service is received.
The absolute value of the difference Δt 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, and if the error value of T1 and T2 is greater than or equal to the preset value, it is impossible to consider T1 and T2 as the same time, and at this time, the target vibration point information is a null point that does not include a vibration signal identifier, the target vibration signal identifier is null, and the motor driving service does not drive the motor to vibrate. At this time, waiting for the next round to acquire the current playing time of the target media file, that is, waiting for the media service to receive the time reading instruction sent by the media driving service again, and acquiring the timing time of the timer, so as to acquire the current playing time of the target media file.
In one embodiment, there is provided an apparatus for controlling an output vibration signal, the apparatus comprising:
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 a vibration starting time and a vibration signal identifier;
