Embodiment 1
[0038] figure 1 The block diagram of the tactile vibration control system of the smart terminal provided in this embodiment, the smart terminal of the present invention can be a handheld device, a wearable device (such as a smart watch, a smart bracelet), or an industrial control device.
[0039] like figure 1 as shown, figure 1 The tactile vibration control system in is an open-loop control system, including: a command generator 11 , a filter 12 , a tactile driver 13 and a linear resonant actuator 14 .
[0040] like figure 1 As shown, the output of command generator 11 is connected to the input of filter 12, the output of filter 12 is connected to the input of haptic driver 13, and the output of haptic driver 13 is connected to the input of linear resonant actuator 14 end.
[0041] The command generator 11 generates an original command signal according to the input signal, and sends the original command signal to the filter 12 . The input signal in this embodiment may be...
Embodiment 2
[0059] In order to further solve the residual phenomenon of tailing of the linear resonant actuator when the driving signal stops driving, this embodiment sets up a plurality of sensors that can monitor or sense the vibration state of the linear resonant actuator, and the characterization of the sensor output The sensing signal of the physical quantity related to the vibration mode is used as the feedback signal to control the physical quantity of the vibration of the linear resonant actuator in real time, and the state of the actuator is more robustly estimated and controlled by an effective integration method to further solve the problem of linear resonant actuation. The residual phenomenon of tailing occurs when the instrument vibrates.
[0060] Figure 5 The block diagram of the tactile vibration control system of the intelligent terminal provided for this embodiment, such as Figure 5 As shown, by setting the sensing module 55, the feedback unit 56 and the comparator 57 ...
Embodiment 3
[0092] Based on the same technical concept as that of Embodiment 1, this embodiment provides a method for controlling tactile vibration of a smart terminal.
[0093] like Figure 8 as shown, Figure 8 For the tactile vibration control method of the smart terminal provided in this embodiment, the control method includes:
[0094] S810. Generate an original command signal according to the input signal.
[0095] In this step, the original command signal is generated according to the input signal as follows:
[0096] Reading the vibration pattern list of the vibration effect library, and selecting a physical quantity sequence representing the vibration effect corresponding to the desired vibration pattern from the vibration pattern list according to the selection instruction in the input signal, and using the physical quantity sequence as the original command signal;
[0097] Alternatively, a physical signal representing a vibration effect derived from the media stream data is ...
