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.
In an embodiment of the invention, a method for generating a vibration signal is provided. By the method, editing and designing of vibration signals according to user demands and instructions can be achieved, and individuation of vibration effects is achieved.
Specifically, in one embodiment, the method for generating the vibration signal may be implemented based on a computer device, where the computer device provides an editing page of the vibration signal, for example, a User Interface (UI), through which a User may input parameters or effects of the vibration signal for editing, and then the parameters or effects are converted into corresponding vibration signals by the computer device. In another embodiment, the method for generating a vibration signal may be implemented based on a vibration signal editing system, where the system includes a computer device for interacting with a user and a server, and parameters or effects of the vibration signal edited by the user are input through the computer device and then sent to the server, and the server converts the parameters or effects into corresponding vibration signals according to the parameters or effects.
In this embodiment, the implementation of the method for generating the vibration signal may be described based on a computer device.
Specifically, as shown in fig. 1, a flow chart of a method for generating a vibration signal is provided. The method for generating the vibration signal specifically includes steps S101 to S104 shown in fig. 1:
Step S101: and acquiring input vibration signal template parameters.
The user or vibration signal designer can input parameters corresponding to the vibration signal to be designed through a preset vibration signal design page to perform the custom design of the vibration signal.
In this embodiment, in the process of designing the vibration signal, the parameters input by the user include parameters of a vibration signal template, where the parameters of the vibration signal template are parameters for identifying the vibration signal template, or parameters corresponding to a specific vibration rhythm of the vibration signal. The vibration signal template parameters are used for determining the vibration rhythm, duration and corresponding waveform of the vibration signal currently designed. The vibration signal template parameters are specifically described in detail in step S102.
Step S102: and respectively determining a plurality of vibration fragments, and target vibration duration and target vibration waveform corresponding to the plurality of vibration fragments according to the vibration signal template parameters.
In this embodiment, the vibration signal template parameter is used to determine a vibration duration and a corresponding vibration waveform corresponding to the final target vibration signal.
In one embodiment, the vibration signal custom designed by the user may be made up of one or more vibration segments. To determine the final vibration effect, a corresponding vibration market and a corresponding vibration waveform for each vibration segment need to be determined.
Specifically, the vibration signal template parameters input by the user include vibration time parameters corresponding to one or more vibration segments, where the vibration time parameters include a vibration duration corresponding to each vibration segment, and time position information corresponding to each vibration segment (for identifying a specific position of the vibration segment in the vibration signal).
In a specific embodiment, step S102 is: determining a plurality of vibration fragments, and target vibration duration and target vibration waveform corresponding to the plurality of vibration fragments according to the vibration signal template parameters, wherein the method further comprises: and respectively determining a target vibration duration and a target vibration waveform corresponding to each vibration segment according to the vibration time parameters.
That is, according to a vibration time parameter (e.g., a vibration time period) determined by the user for each vibration segment, then, according to the vibration time parameter, a corresponding vibration time period can be determined.
For example, the vibration time parameters input by the user include:
1 st vibration segment: vibrating for 50ms;
Suspending vibration: stopping for 200ms;
2 nd vibration segment: vibrating for 1s;
suspending vibration: stopping for 500ms;
3 rd vibration segment: vibration is for 10ms.
According to the vibration time parameter, it can be determined that the vibration signal can be divided into 3 vibration segments, wherein the target vibration duration corresponding to each vibration segment and the pause vibration duration between 2 vibration segments are as follows:
target vibration duration of the 1 st vibration segment: 50ms;
pause vibration duration: 200ms;
target vibration duration of the 2 nd vibration segment: 1s;
Pause vibration duration: 500ms;
target vibration duration of the 3 rd vibration segment: 10ms.
Referring specifically to fig. 3, a schematic diagram of a vibration signal including the above 3 vibration segments is given.
In this embodiment, the determination of the vibration waveform corresponding to each vibration segment may be determined by the identification corresponding to the vibration waveform included in the vibration signal template parameter input by the user. That is, according to the identification corresponding to the vibration waveform input by the user, the corresponding vibration sample waveform is determined, and then the determined vibration sample waveform is taken as the target vibration waveform corresponding to the corresponding vibration fragment.
In another embodiment, the corresponding target vibration waveform may also be determined according to the duration of the corresponding target vibration duration of each vibration segment. Specifically, in a preset vibration waveform database, for each vibration segment, a vibration sample waveform corresponding to the vibration segment is searched for as the target vibration waveform. That is, the correspondence between each target vibration period and the vibration sample waveform is set in advance, and then the corresponding target vibration waveform is determined according to the determined target vibration period.
Specifically, different time lengths correspond to different waveforms, taking 100ms as a threshold duration as an example, and a vibration waveform corresponding relation within 0-100ms is given:
0-20ms: waveform 1;
21-40ms: waveform 2;
41-60ms: waveform 3;
61-80ms: waveform 4;
51-100ms: waveform 5;
100ms or more: a steady state sine wave.
That is, different matched waveforms are set for the vibration duration of the threshold duration, where the waveforms may be shaped waves. Further, the vibration duration above the threshold duration is uniformly set as a steady-state sine wave corresponding to the vibration waveform, that is, how long the vibration duration input by the user is, and how long the corresponding vibration signal vibrates.
It should be noted that, in the design process of the vibration signal in this embodiment, the vibration signal may be composed of 1 or more vibration segments, and whether there is a stop vibration time between each vibration segment is not limited, and the design may be performed according to the needs of the user. In the case that the vibration time is not stopped between the two vibration fragments, it is also necessary to consider the phase coincidence of the adjacent positions of the two vibration fragments to ensure the continuity of the vibration signal.
In order to facilitate the user to perform the custom design of the vibration signal, a plurality of vibration signal templates can be designed in advance, and in step S102, the user does not need to input the vibration time parameter corresponding to each vibration segment, can only input the identification of the vibration signal template designed in advance, and can perform the design of the vibration signal directly according to the corresponding vibration signal template.
Specifically, in step S101, the vibration signal template parameter input by the user includes a vibration template identifier, where the vibration template identifier is an identifier corresponding to a vibration signal template included in the preset vibration signal template library, and the corresponding vibration signal template may be determined according to the vibration template identifier.
As shown in fig. 2, step S102 is given: the step S102 includes steps S1021-S1022 shown in fig. 2, where a specific flowchart of the target vibration duration and the target vibration waveform corresponding to the plurality of vibration segments are determined according to the vibration signal template parameters, respectively:
step S1021: searching a target vibration template corresponding to the vibration template identifier in a preset vibration signal template library according to the vibration template identifier;
Step S1022: and determining the plurality of vibration fragments according to the target vibration template, and determining the target vibration duration and the target vibration waveform corresponding to each vibration fragment.
The preset vibration signal template library comprises a plurality of vibration signal templates which are designed in advance, and the corresponding vibration signal templates can be determined according to the vibration template identification input by a user, namely the target vibration templates. Wherein, each vibration signal template contained in the preset vibration signal template library corresponds to one or more vibration fragments, that is, each vibration signal template is composed of one or more vibration fragments.
Then, after the target vibration template is determined, a plurality of vibration fragments contained in the vibration signal are determined according to the plurality of vibration fragments contained in the target vibration template, and a target vibration duration and a target vibration waveform corresponding to each vibration fragment can be further determined according to the target vibration template.
Step S103: and acquiring the input vibration intensity parameter and/or the vibration frequency parameter, and determining the corresponding target vibration intensity and/or the target vibration frequency.
In addition to determining the target vibration duration and the target vibration waveform corresponding to one or more vibration segments in steps S101-S102, the user-defined vibration intensity and vibration frequency may be further determined according to the user' S requirement. In one embodiment, the vibration intensity and the vibration frequency may be preset fixed values, and then the corresponding target vibration intensity and the target vibration frequency are determined according to the preset fixed values.
In another embodiment, the user may also customize the vibration intensity and frequency. Specifically, the user can determine the vibration intensity and the vibration frequency through a preset UI interface. According to the vibration intensity parameter and the vibration frequency parameter input by the user, the corresponding target vibration intensity and target vibration frequency are further determined, so that the self-defining effect on the vibration signal is further improved.
In a specific embodiment, as shown in fig. 4, a flow chart of the vibration intensity setting is given:
Step S103A1: acquiring input vibration intensity setting operation, wherein the vibration intensity setting operation is touch operation;
Step S103A2: and determining a target pressure value corresponding to the vibration intensity setting operation, and determining the vibration intensity corresponding to the target pressure value as a target vibration intensity according to a corresponding relation between the preset vibration intensity and the pressure value.
The user can determine the intensity of the vibration by touching the magnitude of the pressure value of the screen. For example, the magnitude of the pressure value input by the user is acquired by a touch screen provided on a terminal device such as a mobile phone or a pressure sensor provided at a side (both sides) or other positions of the terminal device to determine the corresponding vibration intensity.
Specifically, a vibration intensity setting operation input by the user is acquired, and the vibration intensity setting operation may be a touch operation input through a touch screen on the terminal device or a pressing operation input through a pressure sensor on the terminal device. The pressure value corresponding to the vibration intensity setting operation input by the user, for example, 1 n, 0.5 n, or the like is acquired. And then determining the vibration intensity corresponding to the obtained pressure value according to the corresponding relation between the preset pressure value and the vibration intensity, and taking the vibration intensity as the final target vibration intensity, wherein the target vibration intensity is the vibration intensity of the vibration signal.
In a specific embodiment, an example of the correspondence between the pressure value and the vibration intensity is given:
pressure value >1 cow: 100% strength;
the pressure value is 0.6-0.8 ox: 80% strength;
The pressure value is 0.4-0.6 ox: 50% strength;
pressure value <0.4 newton: 30% strength.
In other embodiments, the correspondence between the pressure value and the vibration intensity may also be other forms of correspondence or functional relationship.
In this embodiment, the vibration intensity setting operation may be performed by the user by inputting the vibration intensity of the entire vibration signal (i.e., the plurality of vibration fragments), that is, the vibration signal includes the plurality of vibration fragments having the same vibration intensity. In another embodiment, the user may also set a corresponding vibration intensity for each vibration segment separately. That is, the vibration intensity setting operation input by the user includes the vibration intensity setting sub-operation input for each vibration piece, respectively. And then, respectively determining the corresponding vibration intensity of each vibration segment according to the corresponding pressure value, so that the design effect of the vibration signal is further improved, the vibration effect is enriched, and the user experience is improved.
In a specific embodiment, as shown in fig. 5, a schematic flow chart of the vibration frequency setting is given:
step S103B1: acquiring an input vibration frequency setting operation, wherein the vibration frequency setting operation is a sliding operation;
step S103B2: determining a target sliding distance value corresponding to the vibration frequency setting operation;
step S103B3: and determining the vibration frequency corresponding to the target sliding distance value as a target vibration frequency according to the corresponding relation between the preset sliding distance value and the vibration frequency.
In the present embodiment, the user can input a sliding operation to set the vibration frequency at the UI interface of the vibration frequency setting. And then determining the final target vibration frequency according to the end position corresponding to the input sliding operation or the length of the sliding track.
Specifically, according to position information corresponding to a sliding operation input by a user, starting point position information and end point position information corresponding to the sliding operation are included, and then a corresponding target sliding distance value is calculated according to the starting point position information and the end point position information. Here, the sliding distance value may be calculated by a calculation formula of the euclidean distance, or may be calculated by another distance calculation method.
In this embodiment, the larger the sliding distance value is, the higher the corresponding vibration frequency is, which is a correspondence between the preset sliding distance value and the vibration frequency. After the target sliding distance value corresponding to the vibration frequency setting operation is determined, the vibration frequency corresponding to the target sliding distance value is determined according to the corresponding relation between the preset sliding distance value and the vibration frequency, and the determined vibration frequency is taken as the target vibration frequency.
In another embodiment, in the UI interface of the vibration frequency setting, different position information corresponds to different vibration frequency values. When the user inputs the sliding operation, the end position information corresponding to the sliding operation input by the user is acquired, the area where the end position information is located is determined, and different areas correspond to different vibration frequencies. Therefore, the target vibration frequency corresponding to the sliding operation can be determined from the area where the end position information corresponding to the sliding operation is located.
As shown in fig. 6, an interface schematic diagram of the vibration frequency setting is given. In the course of the user input vibration frequency setting operation, in the operation region shown in fig. 6, a sliding operation is input with the center of the operation region as a start point, and end point position information of the sliding operation is acquired, and a corresponding vibration frequency, that is, a target vibration frequency, is determined according to the region where the end point position information is located.
In this embodiment, the vibration frequency setting operation may be performed by the user by inputting the vibration frequency of the entire vibration signal (i.e., the plurality of vibration fragments), that is, the vibration signal includes the plurality of vibration fragments corresponding to the vibration frequency. In another embodiment, the user may also set a corresponding vibration frequency for each vibration segment separately. That is, the vibration frequency setting operation input by the user includes the vibration frequency setting sub-operation input for each vibration piece, respectively. And then, according to the corresponding pressure values, the corresponding vibration frequency of each vibration segment is respectively determined, so that the design effect of the vibration signal is further improved, the vibration effect is enriched, and the user experience is improved.
Step S104: and generating a target vibration signal according to the target vibration duration, the target vibration waveform, the target vibration intensity and/or the target vibration frequency, wherein the target vibration signal is used for driving the motor to vibrate so as to generate different vibration effects.
After each vibration segment and corresponding target vibration duration, target vibration waveform, and corresponding target vibration intensity and target vibration frequency of the vibration signal are determined, a corresponding target vibration signal can be generated according to a preset vibration signal generation algorithm, and the target vibration signal is used for driving the motor to vibrate so as to generate different vibration effects.
That is, after the vibration fragments, the vibration duration, the vibration waveform, the vibration intensity, and the vibration frequency are set by the user, the corresponding target vibration signals can be generated. The vibration effect that the user can design different vibration signals according to own hobbies and demands is achieved, the richness of the vibration effect is improved, and the user experience is improved.
In a specific embodiment, the target vibration signal may be generated by first generating each vibration segment and then stitching the vibration segments to generate the final target vibration signal.
Specifically, in the above-described setting process of the vibration intensity and the vibration frequency, the specific setting process for each vibration piece may be as shown in fig. 7:
step S103C1: respectively acquiring input vibrator intensity parameters corresponding to each vibration segment;
Step S103C2: respectively determining the target vibrator intensity corresponding to each vibration segment according to the vibrator intensity parameter corresponding to each vibration segment;

That is, in inputting the vibration intensity parameter and/or the vibration frequency parameter, it is necessary to acquire the vibrator intensity parameter and/or the vibrator frequency parameter corresponding to each vibration segment by the user, respectively, and then determine the target vibrator intensity and/or the target vibrator frequency corresponding to each vibration segment according to a preset algorithm. Thereby realizing the setting process of the vibration intensity and the vibration frequency of each vibration segment.
Then, in step S104, the process of generating the target vibration signal is a process of generating an overall vibration signal from the plurality of vibration fragments.
Specifically, as shown in fig. 7, the process of generating the target vibration signal further includes:

The target sub-vibration signal corresponding to each vibration segment may be generated by determining the state at the target vibration duration, the target vibration waveform, and the corresponding target vibrator intensity and target vibrator frequency for each vibration segment. And then, according to the target sub-vibration signals corresponding to all the vibration fragments, the corresponding target vibration signals can be spliced, and the custom design process of the vibration signals is completed.
