[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The present invention provides a vibration signal conversion system. Please refer to FIG1 , which is a schematic structural diagram of a vibration signal conversion system provided by an embodiment of the present invention. The vibration signal conversion system 100 includes:

[0039] The signal acquisition module 101 is used to connect to the application to obtain the original vibration signal data in the application, convert the original vibration signal data into the preset protocol vibration signal data according to the preset protocol format, and transmit it to the signal conversion module 102; the format of the original vibration signal data is Rumble format;

[0040] The signal conversion module 102 is used to convert the preset protocol vibration signal data into processed vibration signal data of the corresponding vibration unit according to a preset signal generation method, and output the processed vibration signal data to the vibration unit to drive the vibration unit to generate vibration.

[0041] Specifically, in an embodiment of the present invention, the signal acquisition module 101 can be installed on the same system platform as the application, and mainly acquires Rumble format data (vibration data with only intensity parameters) sent by the Rumble interface of the application. The signal acquisition module 101 includes:

[0042] The vibration pattern matching submodule 1011 is configured to select a corresponding preset vibration pattern based on the type of application and transmit the preset vibration pattern to the signal conversion module; the preset vibration pattern is selected based on at least one factor of the application size, application name, and application type of the corresponding application and matched with the corresponding vibration frequency data;

[0043] Adaptive interface processing submodule 1012, used to obtain the original vibration signal data in the application;

[0044] The adaptive protocol processing submodule 1013 is configured to convert the original vibration signal data into vibration signal data of the preset protocol according to the preset protocol format, and transmit the vibration signal data of the preset protocol to the signal conversion module.

[0045] For the adaptive protocol processing submodule 1013, since the application may use API interfaces of different protocol types (such as XINPUT interface), resulting in inconsistent data formats, it is necessary to convert the data format of the original protocol into the preset protocol format set in the embodiment of the present invention.

[0046] The vibration data ultimately generated from the processed vibration signal data will be different depending on the type of application. More specifically, based on the original vibration intensity, the embodiment of the present invention aims to convert the original signal that only has vibration intensity into a signal that has both intensity and frequency. This frequency can be user-defined to facilitate adjustment under different applications. For example, for gaming applications, the preset strong mode can enhance the vibration frequency based on the original signal, which is suitable for games with more intense visuals; or it can be set to a soft mode, which weakens the vibration frequency based on the original signal, which is suitable for games with a softer visual. How to set the type of the preset vibration mode can be set according to actual needs, and the present invention does not impose specific restrictions on this.

[0047] In the embodiment of the present invention, the signal conversion module 102 can be integrated into the control device or installed externally on the control device, and mainly converts the acquired Rumble data into the processed vibration signal data (vibration data with intensity and frequency parameters) according to a preset signal generation method. The signal conversion module 102 includes:

[0048] A driving submodule 1021 is configured to connect to the vibration unit and drive the vibration unit to generate vibration according to the processed vibration signal data;

[0049] The protocol processing submodule 1022 is configured to negotiate the preset protocol format with the adaptive protocol processing submodule and receive the preset protocol vibration signal data sent by the adaptive protocol processing submodule 1012;

[0050] The mode switching submodule 1023 is configured to receive the preset vibration pattern sent by the vibration pattern matching submodule 1011;

[0051] An adaptive conversion parameter generation submodule 1024 is configured to interface with the driver submodule 1021 to obtain preset parameters of the vibration unit and generate conversion algorithm parameters based on the preset parameters; the preset parameters include at least one of the vibration parameters of the vibration unit, the drive data format, and the drive unit temperature; these vibration parameters are used to optimize signals for different vibration unit types;

[0052] The signal generating submodule 1025 is configured to generate the processed vibration signal data according to the preset protocol vibration signal data, the preset vibration pattern and the preset parameters in accordance with the preset signal generating method.

[0053] The preset signal generation method comprises the following steps:

[0054] Splitting and encoding the preset protocol vibration signal data to obtain bit rate data;

[0055] Encoding the bit rate data according to the preset vibration pattern and the conversion algorithm parameters to obtain waveform data;

[0056] The waveform data is output as the processed vibration signal data recognizable by the vibration unit.

[0057] Because different control devices may have different driving methods for their vibration units, it's necessary to generate processed vibration signal data in a format corresponding to the vibration unit's parameters. For example, audio drivers generate formats like WAV, OGG, and MP3. As shown in Figure 2, compared to the relatively monotonous raw vibration signal data, the processed vibration signal data generated by the vibration signal conversion system of this embodiment of the present invention has richer vibration frequencies and a stronger sense of depth.

[0058] Compared to related technologies, the vibration signal conversion system of the present invention includes: a signal acquisition module for connecting to an application to obtain raw vibration signal data in the application, converting the raw vibration signal data into preset protocol vibration signal data according to a preset protocol format, and transmitting the data to a signal conversion module; a signal conversion module for converting the preset protocol vibration signal data into processed vibration signal data of a corresponding vibration unit according to a preset signal generation method, and outputting the processed vibration signal data to the vibration unit to drive the vibration unit to generate vibration. The above system can output vibration signal data based on the parameters of the application or the controller with the vibration unit, thereby setting different vibration frequencies according to different applications, and allowing users to experience vibration effects that are more in line with the application scenario from the controller with the vibration unit, thereby improving the user experience.
