Based on the embodiments herein, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of the present application.

In order to facilitate understanding of the schemes in the embodiments of the present application, the following description first explains terms in the embodiments of the present application.

(1) Micro control unit (Microcontroller Unit, MCU): the CPU frequency and specification of CPU are properly reduced, and the interfaces of Memory (Memory), counter (Timer), universal serial bus (Universal Serial Bus, USB), A/D conversion, universal asynchronous receiver transmitter (Universal Asynchronous Receiver Transmitter, UART), programmable logic controller (Programmable Logic Controller, PLC), direct Memory access (Direct Memory Access, DAM) and LCD driving circuit are integrated on a single chip to form a chip-level computer for different application occasions to realize different combination control.

(2) Analog-to-digital converter (Analog To Digital Converter, ADC): generally refers to an electronic component that converts an analog signal to a digital signal. A typical analog-to-digital converter converts an input voltage signal into an output digital signal. Since digital signals themselves have no practical meaning, only one relative size is represented. Therefore, any analog-to-digital converter needs a reference analog quantity as a conversion standard, and the most common reference standard is the maximum convertible signal size. And the number of digits output indicates the magnitude of the input signal relative to the reference signal.

(3) Digital-to-analog converters, also known as D/a converters, are devices that convert digital quantities into analog. The D/a converter consists essentially of 4 parts, namely a weighted resistor network, an operational amplifier, a reference power supply and an analog switch. Analog-to-digital converters are typically used in analog-to-digital converters.

It can be read and written at any time and is fast, usually as a temporary data storage medium for an operating system or other program in operation.

(5) Low Pass filtering (Low-Pass Filter): is a filtering mode. The rule of low-pass filtering is that low-frequency signals can normally pass through, while high-frequency signals exceeding a set critical value are blocked and weakened. But the amplitude of the blocking, weakening of the high frequency signal may vary depending on the frequency of the different signals and the different filtering procedures. Sometimes also referred to as High-frequency Cut Filter (High-Cut Filter) or highest Cut Filter (Treble-Cut Filter). In this application, the set threshold may be an amplitude parameter of the first audio data corresponding to the maximum amplitude parameter of the motor.

(6) User Interface (UI): is the medium of interaction and information exchange between the system and the user, which enables the conversion between the internal form of the information and the human acceptable form. The user interface is designed to be interactive communication related software between the user and the hardware, so that the user can conveniently and effectively operate the hardware to achieve bidirectional interaction, the work expected to be completed by the hardware is completed, the user interface is widely defined and comprises a man-machine interaction and a graphic user interface, and the user interface exists in the field of information communication between human beings and machines.

As shown in fig. 1, the process includes the steps of:

101: and acquiring scene information of the current electronic equipment.

It will be appreciated that the gamepad can obtain current context information. The scene information includes various information such as current picture information and/or sound information of the electronic equipment.

102: detecting that the current electronic equipment comprises a vibration event, and detecting an event coordinate of the current vibration event.

It can be understood that the game handle detects that the current game handle contains a plurality of event information, screens the event information, and determines the event information meeting the preset condition as a vibration event, wherein the preset condition can be preset when the electronic equipment leaves the factory or can be preset by a user. A coordinate system is established in a display interface in the electronic equipment in advance, and further the event coordinates of the current vibration event on the display interface are obtained, namely the position of the event triggering the motor is obtained.

103: and matching the corresponding motor identification according to the event coordinates of the current vibration event.

It can be understood that the game handle determines the position of the area in the display interface of the electronic device according to the event coordinates of the current vibration event, wherein the display interface of the electronic device is divided into four areas, and each area corresponds to a different motor identifier in the game handle. Different areas correspond to different motor identifications and numbers of motors in the gamepad. Wherein the motor identification may be motor 1, motor 2, motor 3, motor 4, etc.

Further, a motor identification is determined based on the location of the region in the electronic device of the event coordinates of the current vibration event.

104: and controlling motor vibration corresponding to the motor identification by adopting the vibration effect corresponding to the vibration event.

It will be appreciated that, based on the determination results of steps 101 to 104 described above, the motor corresponding to the motor identification is controlled to vibrate with a matching vibration effect. Specifically, according to a predefined vibration effect library, corresponding vibration effects are matched for the determined vibration event. The event coordinates where the vibration events are located are different, and the corresponding vibration effects are also different.

It can be understood that in the existing vibration feedback scheme, a vibration event contained in scene information in a display interface of the current electronic device is detected by implementing a corresponding relationship between a preset vibration effect and an event coordinate. Further acquiring event coordinates corresponding to the vibration event, and determining the region positions of the event coordinates in the display interface of the electronic equipment, wherein different region positions correspond to different motor identifications. Further, a motor identifier is determined according to the position of the area of the current vibration event in the electronic equipment, and the motor corresponding to the motor identifier is controlled to vibrate with a matched vibration effect.

Specifically, according to a predefined vibration effect library, corresponding vibration effects are matched for the determined vibration event. The event coordinates where the vibration events are located are different, and the corresponding vibration effects are also different.

The existing vibration feedback scheme solves the problem of single vibration effect, but the existing scheme can only achieve the purpose of multiple vibration effects by presetting different vibration effects, so that the preference of a user to different vibration modes can not be detected, and further vibration feedback can not be performed by combining the vibration mode distinction of the preference of the user.

In order to solve the above problems, the present application provides a vibration feedback method applied to an electronic device. Specifically, the method comprehensively determines what vibration frequency and frequency change the electronic equipment adopts to control the motor vibration in the target vibration mode by detecting the target vibration mode to be switched and combining the frequency distribution characteristics of the collected audio signals. The target vibration mode may be one selected from a plurality of preset vibration modes, and the target vibration mode may be, for example, a vibration mode that a user instructs to switch, that is, a vibration mode selected by the user, or a vibration mode that the electronic device identifies a scene match based on a scene perception capability, or the like, which is not limited herein.

Fig. 2 shows a flow diagram of a vibration feedback method according to an embodiment of the present application. It will be appreciated that the subject of execution of the steps in the method may be a vibration feedback device or apparatus that implements the vibration feedback method of the present application. The structure of the specific vibration feedback device or apparatus will be described in detail below, and will not be described in detail herein.

As shown in fig. 2, the process includes the steps of:

201: and detecting a request for indicating to switch to the target vibration mode to play audio, and switching to the target vibration mode.

Illustratively, a request to play audio is detected that indicates a switch to a target vibration mode. It can be appreciated that the user can select a vibration mode that is more closely matched to the current scene based on the use requirements in the current scene. For example, in a party scene the user may select "dynamic mode". In other embodiments, the electronic device may also perform scene sensing recognition according to some preset scene information, so as to automatically select a vibration mode that is more matched with the current scene, and so on. The user can select a required vibration mode through preset vibration mode selection controls on the electronic equipment, wherein the number of the vibration mode selection controls can be K, and each vibration mode selection control can correspond to different vibration modes. In other embodiments, the vibration mode selection control may be set to only 1, and the user may select the target vibration mode through different pressing times. For example, pressing once may select a first vibration mode and pressing twice may select a second vibration mode. When the current vibration mode is in the last vibration mode, the user presses the vibration mode selection control and then switches to the first vibration mode, and then the target vibration mode is selected according to the current scene. The target vibration mode may also be selected by the time the vibration mode selection control is pressed, without limitation.

In other embodiments, the user may select a vibration mode corresponding to the current scene through a UI interface in the upper computer or a vibration mode selection interface provided by the application software. The host computer may be a software module in the electronic device, which is used to provide a vibration mode option for the user, or may be another electronic device connected to the electronic device, in some embodiments, the host computer may be a mobile phone, and the electronic device connected to the host computer may be a sound box or a game pad, for example, which is not limited herein.

It can be appreciated that detecting a vibration mode selected by a user corresponding to a current scene, determining the vibration mode selected by the user, and performing vibration mode switching.

202: and acquiring first audio data based on the switched target vibration mode.

The first audio data may be an audio data stream outputted after being parsed by a decoder from audio files of various formats, for example. Wherein the first audio data comprises at least an amplitude parameter.

It will be appreciated that different vibration modes correspond to different acquisition rates, first audio data is acquired based on the switched target vibration mode, and the acquired first audio data is converted into a digital signal.

203: and executing preset processing on the collected first audio data in the target vibration mode, and determining a first driving parameter corresponding to the first audio data.

It is understood that the first driving parameter includes at least a first amplitude parameter. In addition, in order to bring better vibration effect to the user, different audio data processing modes can be preset for different vibration modes on the electronic equipment. For example, the audio data processing mode preset for the first vibration mode may be different from the audio data processing mode preset for the second vibration mode.

Specifically, when the target vibration mode is the first vibration mode, the collected first audio data is divided into a plurality of continuous audio units, and the plurality of continuous audio units are subjected to low-pass filtering processing once. And obtaining the peak value of each audio unit after filtering, and comparing the peak values of the audio units to obtain the maximum value of the peak value of each audio unit, wherein the maximum value of the peak value is used as a first driving parameter.

And when the target vibration mode is the second vibration mode, comparing the acquired first audio data with a preset value, and counting the number of absolute values of the audio data which are larger than the preset value in the first audio data, so as to calculate the percentage of the number of the absolute values of the audio data which are larger than the preset value in the first audio data. And further comparing the calculated percentage with a preset percentage, and judging that the first audio data need to vibrate when the calculated percentage is larger than the preset percentage. The predetermined value and the preset percentage can be adjusted according to actual situations and requirements, and are not limited herein.

204: and acquiring a second driving parameter corresponding to the target vibration mode, and determining a third driving parameter for driving the motor to vibrate based on the first driving parameter and the second driving parameter.

The second driving parameter includes at least a preset vibration duration and a second amplitude parameter corresponding to the target vibration mode. The third driving parameter at least comprises a preset vibration duration corresponding to the target vibration mode and a third amplitude parameter determined based on the first amplitude parameter and the second amplitude parameter.

It will be appreciated that different vibration modes correspond to different periods of vibration. When the target vibration mode is the first vibration mode, a first sine wave of a motor driving waveform is generated in combination with a natural frequency FO of the motor according to a maximum value of peak values of each audio unit. And then, calculating to obtain a complete motor driving waveform according to the preset vibration duration, and generating motor driving data, namely a third driving parameter. In order to obtain better vibration feedback effect, the vibration sense is gradually reduced from strong to weak until the vibration sense is reduced to zero. Furthermore, between two consecutive audio units, the motor needs to remain stationary, so no motor drive data needs to be generated. The vibration duration corresponding to the first vibration mode may be adjusted according to the requirement, which is not limited herein.

In this application, the second vibration mode is suitable for changing audio data having no regularity or abrupt change. When the collected first audio data is judged to need to vibrate, a motor driving waveform is generated according to the maximum amplitude and the natural frequency F0 which can be born by the motor. In order to obtain a better vibration feedback effect, in the second vibration mode, the preset vibration duration of the driving motor may be a sine period.

It will be appreciated that motor drive data, i.e. the third drive parameter, may be derived from the generated motor drive waveform and motor vibration duration.

205: and driving the motor to vibrate by adopting the determined third driving parameter.

It can be understood that the intensity of the motor vibration is controlled by the voltage across the motor. Therefore, the motor driving module in the electronic equipment converts or amplifies the generated motor driving data, namely converts or amplifies the third driving parameter to obtain a voltage value for driving the motor to vibrate, so that the motor is driven to vibrate according to the obtained voltage value. It will be appreciated that the different modes of vibration correspond to one or more of the motors, and that when the motors are driven to vibrate, it may be that the one or more motors are driven to vibrate together.

Specific implementations of the first vibration mode and the second vibration mode in the above steps 201 to 205 to achieve different vibration feedback effects will be described in detail below. It should be understood that the first vibration mode and the second vibration mode are only illustrated by way of example, and are not limited to the number of vibration modes in the present application. In other embodiments, other vibration modes may be included, without limitation.

In other embodiments, the acquisition rate may be adjusted according to actual requirements, which is not limited herein. The control module of the electronic equipment collects the audio data, divides the collected first audio data into a plurality of continuous audio units, performs low-pass filtering processing on each of the plurality of continuous audio units once, and removes high-frequency signals. The specific low-pass filtering formula is as follows:

y[k]＝1.8521*y[k-1]-0.8623*k[k-2]+0.0026*x[k]+0.0051*x[k-1]+0.0026*x[k-2]

wherein, y [ k ] is the first audio data output by the kth time, y [ k-1] is the first audio data output by the kth-1 time, and y [ k-2] is the first audio data output by the kth-2 time; x k is the first audio data of the kth input, x k-1 is the first audio data of the kth-1 input, x k-2 is the first audio data of the kth-2 input; coefficients 1.8521, 0.8623 … in the formula can be adjusted according to the requirements in actual implementation scenes, and the coefficients are not limited herein.

Further, the peak point of each audio unit of the first audio data may be determined, for example, by sampling the data [ k ] of the current frame, the data [ k-1] of the previous frame, and the data [ k+1] of the next frame; if data [ k-1] < data [ k ] > data [ k+1] and data [ k ] >3000, then data [ k ] is considered to be the peak point, data [ k ] is stored into the storage location designated by the control module, and this point is counted as peak [1]. The next peak point is determined according to the method, and is sequentially peak [2], peak [3] and the like, wherein the peak point can be three or more, and the method is not limited. For example, the peak point of an audio unit shown in fig. 5, it can be seen from fig. 5 that when peak [1] < peak [2] > peak [3], peak [2] is determined as the highest point of the audio unit, and is also the maximum peak point of the audio unit. It will be appreciated that the waveform diagram of fig. 5 may be an enlarged schematic of a portion of the waveform diagram of fig. 4, and that the ordinate unit of the waveform diagram of fig. 5 may also be decibels (dB).

Further, a sine wave having a frequency equal to the natural frequency F0 of the motor and having a magnitude equal to the maximum peak point of the first audio data, i.e., peak [2], is generated. In the embodiment of the application, in order to meet the corresponding vibration situation, the use experience sense of the user is improved, the vibration sense is gradually reduced from strong to weak, the reduction is zero finally, and the whole vibration process lasts 300ms. As shown in FIG. 6, the maximum amplitude of the motor driving waveform is about 2.1X10-4 dB, and the frequency is 170 Hz. In the present embodiment, one sinusoidal waveform has a duration of about 1000/170ms, which is about 5.882ms, and 300ms has about 51 sinusoidal waveforms. In order to better obtain strong to weak vibration feeling, the amplitude of each sine wave from the second sine wave is 2.1X10-4/51 of the last amplitude.

In other embodiments, the corresponding motor driving waveform may also be generated according to the actual maximum peak point of the collected first audio data and the natural frequency of the motor. The motor driving waveform of the next audio data is continuously generated according to the method of generating motor driving waveform described above, as in FIG. 7, with a maximum amplitude of 1.7X10-4 dB and a gradually decreasing sinusoidal waveform with a frequency of 170 HZ. For better vibration feedback, the first vibration mode is between two consecutive audio data, and the motor needs to remain stationary, and no data need be input to the motor drive module.

It will be appreciated that the abscissas of the waveforms of the motor drive data shown in fig. 6 and 7 described above both represent audio amplitude values in dB, and the ordinates represent frequency in Hz.

Further, the control module of the electronic device sends the generated motor driving data to the motor driving module. It can be understood that the intensity of the motor vibration sense is controlled by the voltages at the two ends of the motor, so that the motor driving module in the electronic device converts or amplifies the generated motor driving data to obtain a voltage value for driving the motor to vibrate, thereby driving the motor to vibrate according to the obtained voltage value. It will be appreciated that in the first vibration mode, the amplitude of each sine wave in the generated drive waveform is different. Therefore, after the motor driving module is converted or amplified, the amplitude of the obtained voltage waveform for driving the motor to vibrate is also different, so that the vibration effect from strong to weak can be realized.

As can be seen from fig. 8, the first audio data change at this time is relatively complex and irregular, and is not suitable for the audio data processing manner of the first vibration mode. Therefore, in order to obtain a better vibration effect, the user can select the second vibration mode. In other embodiments, the second vibration mode may be, for example, a dynamic mode or a game mode, without limitation. The vibration mode does not filter the acquired first audio data.

It can be appreciated that in the second vibration mode, the electronic device may collect the first audio data according to a preset collection amount of the first audio data. And when the percentage of the absolute value of the collected first audio data which is larger than the preset value in the collected first audio data exceeds the preset percentage, judging that the first audio data has rhythm points needing to vibrate. A motor driving waveform is generated based on the maximum amplitude that the motor can withstand and the natural frequency F0. In order to obtain a better vibration feedback effect, in the second vibration mode, the vibration duration of the driving motor may be one sinusoidal period.

The motor driving waveform is a sine wave with the amplitude of the audio data corresponding to the maximum amplitude which can be born by the motor and the frequency of the sine wave being the natural frequency F0 of the motor. In order to bring better vibration experience to the user, in the second vibration mode, only the motor can be driven to vibrate by one sine waveform for each rhythm point of vibration.

Fig. 9 shows a first audio data diagram of a shooting game in continuous shooting.

As shown in FIG. 9, points labeled 1, 2, 3 may represent successive shots of a certain shot-like game that are detected.

According to the first audio data map shown in fig. 9, the control module in the electronic device may preset that the first audio data is collected once for 1024 first audio data points, the time required for collecting once is about 20.33ms, the collection rate of the second vibration mode is 48K, that is, 48000 times per second, and the specified and predetermined amplitude is 2.8x104db, which is 85% of the maximum amplitude that can be borne when the motor vibrates. In other embodiments, the predetermined value may be adjusted according to the needs of the user.

Fig. 10 is a first audio data plot of fig. 9 with the point labeled 1 enlarged, and fig. 11 and 12 are corresponding first audio data plots of fig. 9 with the points labeled 2 and 3 enlarged. As can be seen from the above-described fig. 10 to 12, each first audio data rhythm point requiring vibration is composed of a plurality of first audio data. Therefore, when one rhythm point appears, the first audio data of each rhythm point can be collected independently, and when the absolute value of the collected first audio data is larger than the preset value and the number of the collected first audio data exceeds 20 percent of the collected first audio data, the point that the first audio data appears and needs to vibrate is judged. The abscissa of the waveform diagrams of the audio data shown in fig. 8 to 12 represents the audio amplitude in dB, and the ordinate represents the sampling time in ms.

Therefore, based on the above determination result, a motor driving waveform in dB on the abscissa and Hz on the ordinate is generated, for example, a motor driving waveform having an amplitude of 3.2767×10≡4dB and a frequency F0 of 170HZ is shown in FIG. 13. In order to obtain a better vibration effect, in the second vibration mode in the embodiment of the application, the motor driving module only drives the motor to vibrate by one sine wave, and the vibration duration is 1000/170ms and is equal to 5.882ms. Further, the control module sends the generated motor driving data to the motor driving module. The motor driving module converts or amplifies the generated motor driving data to obtain a voltage value for driving the motor to vibrate, so that the motor is driven to vibrate according to the obtained voltage value.

As shown in fig. 14, the apparatus includes one or more vibration mode selection controls, a speaker, a control module MCU, a motor drive module, and one or more motors. When only one key is pressed, different vibration modes are selected through different key times, for example, a first vibration mode is selected by pressing, a second vibration mode is selected by pressing, when the current vibration mode is in the last vibration mode, a user firstly switches to the first vibration mode after pressing the key, and then the corresponding vibration mode is selected according to the requirement. The vibration mode selected by the user can also be determined by the time of pressing the function key for a long time, without limitation.

The ADC peripheral equipment of the control module MCU monitors the loudspeaker in real time, and when the loudspeaker is detected to be started, first audio data are acquired based on the current vibration mode, wherein the acquisition modes and the acquisition rates corresponding to different vibration modes are different. The collected first audio data is further stored in a designated storage location in the control module MCU, which may be a RAM, for example. The control module MCU processes the first audio data according to a first audio data processing method corresponding to the current vibration mode to generate motor driving data for driving the motor to vibrate, the motor driving data comprise motor driving waveforms and motor vibration time length, and the control module MCU sends the generated motor driving data to the motor driving module through a 12C/12S/DAC/GPIO pin.

And the upper computer sends the selected result to the vibration feedback device through the communication module, and the external communication module of the control module MCU receives vibration mode selection information sent by the upper computer. The communication module in the upper computer and the communication module of the vibration feedback device can adopt wired or wireless communication.

The control module MCU switches the current vibration mode to the vibration mode selected by the user based on the received vibration mode selection information. The ADC peripheral equipment of the control module MCU monitors the loudspeaker in real time, and when the loudspeaker is detected to be started, first audio data are acquired based on the current vibration mode, wherein the acquisition modes and the acquisition rates corresponding to different vibration modes are different. The collected first audio data is further stored in a designated storage location in the control module MCU, which may be a RAM, for example.
