[0033] The terms “first”, “second”, and “third” and the like in the specification and claims of the present application and the description of the drawings are used to distinguish different objects, and are not used to limit a specific order.

[0034] In the present application, the terms “include”, “contain” or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement “including a…” does not exclude the presence of another identical element in the process, method, article or device including the element.

[0035] The linear motor is arranged in an electronic device, and is used to output vibration feeling by vibration. In different scenarios of the electronic device, the linear motor is controlled to vibrate to produce different vibration effects, so that the user perceives the vibration feeling to prompt the user or feedback to the user operation, as follows:

[0036] 1. Different vibration effects can be corresponded to different service scenarios (for example, time reminder, receiving information, incoming call, alarm clock, game, etc.).

[0037] 2. Feedback to touch. For example, different vibration effects can be used for touch operations on different applications (e.g. taking photos, playing audio, etc.). Different vibration effects can also be used for touch operations on different areas of the display screen.

[0038] Linear motors commonly used in electronic devices include X-axis linear motors (also known as square or horizontal linear motors) and Z-axis linear motors (also known as circular or vertical linear motors). Figure 1a The structure and application examples of the X-axis linear motor are shown in Figure 1b The structure and application examples of the Z-axis linear motor are shown in

[0039] As shown in Figure 1a The X-axis linear motor has a long or square shape. Assuming that the X-axis is the horizontal axis, the Y-axis is the vertical axis, and the Z-axis is the vertical axis perpendicular to the X-axis and the Y-axis, the mover of the X-axis linear motor can move in the X-axis or Y-axis direction, and a longer stroke can be achieved. The X-axis linear motor is installed in the electronic device along the X-axis direction, and can provide vibration sensation in the X-axis direction. If it is installed along the Y-axis direction, it can provide vibration sensation in the Y-axis direction.

[0040] As shown in Figure 1b The Z-axis linear motor has a cylindrical shape, and the mover can move in the Z-axis direction. The Z-axis linear motor is arranged in the electronic device, and can bring vibration sensation in the thickness direction of the electronic device.

[0041] In order to achieve stronger functions and better user experience, the vibration of the linear motor can be designed for different business scenarios of the electronic device. For example, during the process of playing music on the mobile phone, the linear motor vibrates with the rhythm of the music. However, there is a possibility of overlap between different businesses of the electronic device, for example, receiving information during the process of playing music on the mobile phone, that is, the music playing business overlaps with the information business. In the case of overlap between different businesses of the electronic device, the vibration of the linear motor in a certain business scenario may interfere with other businesses. In the above example, the user views the information, and the mobile phone still plays music, and the linear motor is still controlled to vibrate with the music, which will interfere with the user's viewing of the information.

[0042] Specifically, assuming that the electronic device is executing a program implementing a first event (such as audio playing) and a second event (such as a short message application) is triggered (such as receiving a short message), the program implementing the first event is suspended, and the program implementing the second event is executed. After the second event is completed, the program implementing the first event is continued. Alternatively, the first event and the second event are executed simultaneously, that is, the program implementing the first event and the program implementing the second event are executed in parallel.

[0043] Simply speaking, interruption is that the execution of an event is interrupted, or a new event is added in parallel with the execution of another event.

[0044] Interrupted event refers to interrupting the execution of an event, or adding a new event in parallel with other events while other events are being executed.

[0045] It can be seen that the vibration originally designed for the business scenario to achieve a better user experience may, in certain cases, actually reduce the user experience. Therefore, the vibration function of the electronic device needs to be further improved. In order to improve the vibration function of the electronic device and avoid the possibility of reducing the user experience, the present application provides a driving waveform adjustment method and device.

[0107] The driving waveform adjustment method described in the embodiments of the present application can be applied to Figure 3a The driving waveform processing module, and further, the generation module of the vibration description file.

[0108] The driving waveform adjustment method described in the embodiments of the present application will be described in detail below.

[0109] Figure 4a A driving waveform adjustment method disclosed in the embodiments of the present application includes the following steps:

[0110] S401, an interrupt event is monitored.

[0111] The information, such as an identifier, of the interrupt event to be monitored can be configured in advance according to the requirements, and after the interrupt event information is monitored, it is determined that the interrupt event is monitored.

[0112] S402, in response to the interrupt event, a dynamic description file corresponding to the interrupt event is obtained.

[0113] The vibration description file is used to describe the vibration parameters of the vibration waveform, such as the frequency and amplitude of the vibration waveform. The dynamic description file refers to the vibration description file describing the vibration parameters for controlling the vibration of the linear motor during the occurrence of the interrupt event.

[0114] Corresponding to the dynamic description file is a static description file, which refers to a vibration description file describing the vibration parameters for controlling the vibration of the linear motor in the case where the interrupt event does not occur.

[0115] That is, in the case where the interrupt event does not occur, the static description file is used to control the vibration of the linear motor, and in the process of the occurrence of the interrupt event, the dynamic description file is used to control the vibration of the linear motor, so as to alleviate the interference of the vibration of the linear motor on the interrupt event.

[0116] In this embodiment, the interrupt event is receiving a short message by a short message application, and the interrupted event is playing music.

[0117] The correspondence between the interrupt event and the dynamic description file can be preconfigured, for example, the identifier of the corresponding interrupt event is written in the dynamic description file.

[0118] Optionally, the dynamic description file can be preconfigured, and the step of obtaining the dynamic description file from the storage space can also be performed in response to the interrupt event. The generation method of the dynamic description file will be described in the following embodiments.

[0119] S403, adjusting the driving waveform by using the dynamic description file corresponding to the interrupt event.

[0120] As described above, the dynamic description file and the static description file both describe vibration parameters, for example, amplitude and frequency. In addition, the dynamic description file is used to reduce the interference of the vibration of the linear motor on the interrupt event. Therefore, it can be understood that at least one of the vibration parameters described in the dynamic description file has a smaller value than the vibration parameter described in the static description file.

[0121] For example, the amplitude of the transient waveform 01 described in the static description file is 0.9, and the amplitude of the transient waveform 02 described in the dynamic description file is 0.3. The frequency of the transient waveform 01 described in the static description file is the same as the frequency of the transient waveform 02 described in the dynamic description file.

[0122] Therefore, the specific implementation steps of S403 are as follows:

[0123] S4031, comparing the difference between the vibration parameters described in the static description file and the vibration parameters described in the dynamic description file.

[0124] For example, the difference between the amplitude value described in the static description file and the amplitude value described in the dynamic description file is compared in sequence. It can be understood that the parameters to be compared can be preconfigured, and only the parameters that have a greater impact on the vibration sensation, for example, the amplitude, are compared to reduce the calculation amount.

[0125] The specific obtaining process of the static description file will be described in the following embodiments.

[0126] It can be understood that the vibration parameters described in the static description file can be the same as or different from the vibration parameters described in the dynamic description file.

[0127] Further, the kind of vibration parameters described in the dynamic description file is a subset of the kind of vibration parameters described in the static description file. That is, because the dynamic description file is used in the case of interrupt event, in combination with the above-mentioned application scenarios, it is possible that all parameters of the driving waveform do not need to be adjusted, but only the parameters with strong correlation with the vibration sensation are adjusted, therefore, the dynamic description file can only describe the parameters with strong correlation with the vibration sensation, and therefore, the kind of parameters described in the dynamic description file can be less than the kind of parameters described in the static description file.

[0128] For example, the static description file for controlling the linear motor to follow the vibration of the played music includes parameters such as amplitude, frequency, vibration time, etc., while the static description file for controlling the linear motor to vibrate in the process of executing the short message application only includes the amplitude. When comparing the two files, only the values of the amplitudes need to be compared, so as to reduce the cost of comparison (including the time delay that can be felt by the user, etc.).

[0129] It can be understood that the difference refers to the difference between the values of the same parameters.

[0130] S4032, generating an adjustment coefficient according to the difference.

[0131] For example, the amplitude adjustment coefficient is generated according to the difference between the values of the amplitude described in the static description file and the amplitude described in the dynamic description file.

[0132] S4033, adjusting the driving waveform converted from the static description file using the adjustment coefficient.

[0133] For example, the amplitude adjustment coefficient is used to adjust the amplitude of the driving waveform converted from the static description file. Further, for example, the amplitude adjustment coefficient is 0.3, and the amplitude of the driving waveform is multiplied by 0.3 to obtain the adjusted amplitude.

[0134] Still taking the scenario of receiving information in the process of playing music on the mobile phone as an example: after the short message is received by the information application, the electronic device adjusts the driving waveform, for example, the amplitude of the driving waveform is multiplied by the adjustment coefficient 0.3, so that the intensity of the driving waveform following the vibration of the music is weakened, thereby reducing the interference on the user viewing the short message.

[0135] It can be understood that, optionally, during the duration of the interrupt event, the driving waveform is adjusted using the dynamic description file, after the interrupt event ends, the adjustment of the driving waveform according to the dynamic description file is stopped, and the driving waveform converted from the vibration waveform described in the static description file is still used to drive the linear motor.

[0136] In summary and in combination with the above scenarios, in the process of playing music without receiving information, the vibration waveform described by the static description file is converted into a driving waveform, and then the driving waveform is used to control the linear motor vibration, so that the linear motor vibrates with the music. After receiving the information, the vibration waveform described by the dynamic description file is used to adjust the driving waveform, so as to reduce the amplitude of the driving waveform. In the case of the user viewing the information, the amplitude of the linear motor will be smaller, so as to reduce the interference on the user.

[0137] It can be seen that the adjustment method of the driving waveform described in the embodiment responds to the interrupt event, uses the dynamic description file to adjust the driving waveform, so that the vibration of the linear motor adapts to the interrupt event and adjusts the vibration feeling following the change of the scene, thereby providing a better vibration feeling experience for the user. Moreover, the vibration function is also expanded.

[0138] As mentioned above, the static description file and the dynamic description file can be preconfigured in the storage space, and can be used Figure 1a The driving waveform processing module shown in the figure can be read and used from the storage space, or generated by Figure 1a The driving waveform processing module shown in the figure.

[0139] Figure 5a The flow of the generation method of the static description file includes the following steps:

[0140] S501, display a first basic waveform.

[0141] A first interface can be presented, and the first interface displays a first basic waveform.

[0142] The first basic waveform is a waveform obtained according to the characteristics of the object to which the vibration is applied, or a waveform selected from a preconfigured scene vibration feeling library.

[0143] Specifically, the object to which the vibration is applied can be audio, and the basic waveform is generated according to the sound characteristics of the audio, such as envelope, frequency, amplitude, timbre and rhythm, etc. It can be understood that the object to which the vibration is applied can be received from the outside, such as receiving an audio file imported by the user. For example, Figure 5b As shown in the interactive interface, the user can click the musical note icon 51 in the upper right corner of the interactive interface to import an audio file, and the interactive interface displays a basic waveform generated according to the imported audio file.

[0144] Specifically, the preconfigured scene vibration feeling library includes waveforms corresponding to vibration feelings in various scenes, such as waveforms corresponding to vibration feelings in a (game) gun shooting scene and waveforms corresponding to vibration feelings in a (game) explosion scene. The waveform files in the scene vibration feeling library can be added, deleted or modified.

[0145] It can be understood that an interactive interface can be displayed, and the user can select a waveform corresponding to a vibration effect in at least one scene from the scene vibration library based on the interactive interface. Figure 5b As shown in the interactive interface, the user can click the file icon 52 in the upper right corner of the interactive interface to import the waveform in the scene vibration library, and the selection instruction triggered in response to the selection operation of the user selects the waveform selected by the user from the scene vibration library as the base waveform.

[0146] S502, in response to the adjustment instruction of the first base waveform, a static description file is generated.

[0147] The adjustment instruction in this step can indicate adjustment of parameters of the waveform, such as adjustment of vibration parameters such as frequency, start time, duration and amplitude of the first base waveform, and can also indicate superposition of waveforms, such as superposition of first base waveforms of different vibration events.

[0148] The multiple waveforms superimposed are not limited to events. The specific calculation method of waveform superposition can refer to the prior art, for example, amplitude addition, which will not be described here. The purpose of waveform superposition is to present extended vibration effects by superposition, which can support superposition of vibration effects of multiple scenes, so that the user's vibration experience is more rich.

[0149] In response to the adjustment instruction, the base waveform is adjusted, and in response to the instruction issued by the save control 55, a vibration description file is generated. Optionally, in response to the instruction issued by the save control 55, the adjusted waveform, i.e. the waveform described in the vibration description file, can also be displayed on the interactive interface.

[0150] S503, in the case where the value of the parameter of the adjusted waveform exceeds the adjustment limit value, a prompt information is displayed.

[0151] The prompt information is used to prompt that the adjustment exceeds the adjustment limit value.

[0152] Optionally, in the case where the value of the parameter of the adjusted waveform exceeds the adjustment limit value, the adjustment instruction is not responded.

[0153] Specifically, the adjustment limit value can include but is not limited to an amplitude limit value, a start time limit value and a stop time limit value.

[0154] The amplitude limit value can be determined according to the maximum displacement of the linear motor to be controlled. The start time limit value and the stop time limit value can be determined according to the properties of the linear motor to be controlled.

[0155] The purpose of setting the adjustment limit value is to protect the linear motor to be controlled from being damaged.

[0156] Compared with the way that the skilled person in the prior art writes code to form a vibration description file, the vibration description file can be obtained more efficiently, and the technical threshold for the user to obtain the vibration description file can be lowered. Because the basic waveform is provided first, the user can obtain the required vibration description file based on the basic waveform, thereby further improving the efficiency and lowering the technical threshold for the user to obtain the vibration description file.

[0157] The generation process of the dynamic description file is different from the process shown in Figure 5a The difference between the process shown in Figure 5a The other steps are the same as the process shown in

[0158] It should be noted that in the above embodiments, the interactive interface is only one implementation, which is more convenient and has better user experience, but the adjustment method of the basic waveform is not limited to being implemented based on the interactive interface.
