In the following description, the inventive embodiment numbers are merely for the purpose of description and do not represent the merits and merits of the embodiments.
Example 1
As shown in fig. 1, an embodiment of the present invention provides a low-frequency vibration compensation method, which is improved based on a driving signal of a vibration device to increase the low-frequency vibration of the vibration device, and includes, but is not limited to, the following steps:
s101, after a vibration device receives a vibration instruction, and before the vibration device responds to the vibration instruction, acquiring an original vibration signal for driving the vibration device to vibrate.
In the above step S101, the vibration instruction may be an instruction that the user operates the electronic apparatus to cause the electronic apparatus to transmit to the vibration device, such as a pressing instruction on the display screen of the electronic apparatus.
In a specific application, the vibration device should immediately respond to the operation of the user on the electronic device to generate vibration, but in the embodiment of the invention, before responding to the vibration instruction, the vibration device is further caused to execute step S101 and step S102, and when the vibration device responds to the vibration instruction, the vibration device is caused to execute step S103, so that a stronger vibration feeling is finally generated.
In a specific application, the short signal for driving the vibration device to vibrate is divided into an acceleration section signal and a brake section signal, and the initial value of the acceleration section signal is actually a sinusoidal signal which is not conventional, namely the original vibration signal in the step S101.
S102, setting a starting vibration compensation signal with a target period according to the peak period of the original vibration signal.
In the above step S102, the original vibration signal may be a sinusoidal signal whose peak period has a value substantially the same as that of the function period, and the waveform of the vibration start compensation signal set according to the original vibration signal should be the same as or similar to that of the original vibration signal.
The embodiment of the invention also shows a detailed implementation manner of the step S102, including:
setting the target period to be an integer multiple of a peak period of the original vibration signal, and setting each target period of the starting compensation signal to include a voltage driving period and a no-signal output period.
Wherein, in the voltage driving period, the peak time point of the starting compensation signal coincides with the peak time point of the original vibration signal;
wherein, in the no-signal output period, the vibration device does not receive a signal.
In the embodiment of the invention, only one waveform peak value appears in one target period of the oscillation starting compensation signal, the waveform peak value only appears in the voltage driving period, and the voltage driving period does not exist in other times when the waveform peak value of the original oscillation signal appears.
In one embodiment, when the target period of the oscillation starting compensation signal is n×k and k is a positive integer greater than 1, the duration of the voltage driving output period in one of the target periods isThe duration of the no signal output period is +.>
When the target period of the oscillation starting compensation signal is n multiplied by k and k is 1, the duration of the voltage driving output period in one target period isThe duration of the no signal output period is +.>
As shown in fig. 2 and 3, the embodiments of the present invention further show that when k is 1 and k is 2, according to the peak period of the original vibration signal, the set vibration start compensation signal with the target period:
the upper line of fig. 2 and 3 represents an original vibration signal, the lower line of fig. 2 and 3 represents a start-up compensation signal having a target period, and a voltage driving period a and a no-signal output period B included in one period of the start-up compensation signal are marked in fig. 2, and a voltage driving period a 'and a no-signal output period B' included in one period of the start-up compensation signal are marked in fig. 3.
It can be seen that, in a target period, if the original vibration signal has a waveform peak value and the oscillation starting compensation signal has a waveform peak value, the waveform peak value of the oscillation starting compensation signal coincides with a peak value time point of the original vibration signal. In a target period, if the original vibration signal has a plurality of waveform peaks, the vibration starting compensation signal still has one waveform peak, and then the waveform peak of the vibration starting compensation signal still coincides with a peak time point of the original vibration signal, that is, only one waveform peak of the vibration starting compensation signal is included in the target period, and the vibration starting compensation signal is in a voltage driving period.
S103, enabling the vibration device to respond to the vibration instruction, driving the vibration device through the vibration starting compensation signal, and adjusting the waveform peak value of the vibration starting compensation signal so as to enable the vibrator of the vibration device to collide with the shell.
The vibrator of the vibrating device is impacted with the shell and is used for compensating low-frequency vibration sense of the vibrating device;
wherein when the peak period of the original vibration signal is n and the target period of the oscillation starting compensation signal is n×k, the impact frequency of the vibrator and the housing isk is a positive integer.
In the step S103, the waveform of the oscillation starting compensation signal is the same as or similar to the waveform of the original vibration signal, but the period of the oscillation starting compensation signal is in a multiple relationship, and as can be seen from the above, the frequency of the oscillation starting compensation signal is always smaller than that of the original vibration signal, so that the oscillation sense is not improved by increasing the frequency of the signal in the embodiment of the invention, and the oscillation sense compensation method provided in the embodiment of the invention can be applied under the low-frequency condition.
In step S103, the adjusted oscillation starting compensation signal is based on the original oscillation signal, and the period and the waveform peak value in the period are changed, so that when the oscillation device is driven by the adjusted oscillation starting compensation signal, the input of the original oscillation signal is not blocked, and another driving signal is not input to the oscillation device.
In a specific application, if the target period of the oscillation starting compensation signal is 0.1s, the user will feel the oscillation at intervals of 0.1s, that is to say, the user has the oscillation experience with the frequency of 10 Hz.
In the embodiment of the invention, the waveform peak value of the oscillation starting compensation signal corresponds to the oscillation sensing intensity, the target period of the oscillation starting compensation signal corresponds to the oscillation sensing frequency, and the user can feel the oscillation sensing experience under different frequencies by adjusting the target period.
The embodiment of the invention also shows a detailed implementation manner of the step S103, including:
s1031, obtaining a standard waveform peak value corresponding to vibration sense requirements;
s1032, calculating a target input voltage required at a peak time point of the oscillation starting compensation signal according to the standard waveform peak value;
s1033, setting pulse voltage according to the target input voltage and the target period;
s1034, inputting the vibration starting compensation signal and the pulse voltage into the vibration device so as to enable the vibrator of the vibration device to collide with the shell;
and the pulse voltage is used for increasing the input voltage of the vibration device to the target input voltage when the vibration device is driven by the regulated vibration starting compensation signal, so that the waveform peak value of the vibration starting compensation signal reaches the standard waveform peak value.
In the above steps S1031 to S1034, each waveform peak of the oscillation start compensation signal is raised by the periodic pulse voltage to reach the standard waveform peak corresponding to the oscillation sense requirement.
In a specific application, the standard waveform peak value corresponding to the vibration sense requirement indicates that the corresponding voltage value can enable the vibrator of the vibration device to collide with the shell.
In a specific application, the pulse voltage has periodicity, and the period of the pulse voltage should be the same as the peak period of the oscillation starting compensation signal.
As shown in fig. 4 and 5, the embodiment of the present invention also exemplarily shows a waveform schematic diagram of the oscillation starting compensation signal after adjusting the waveform peak value, and a frequency response curve in the vibration device after driving the vibration device by the oscillation starting compensation signal after adjusting the waveform peak value.
In fig. 4, the oscillation starting compensation signal after the waveform peak value is adjusted has a higher waveform peak value, and the waveform peak value indicates that the corresponding voltage value can enable the vibrator of the vibration device to collide with the shell.
In fig. 5, the curve is the frequency response curve of the vibration device when the low-frequency vibration compensation method provided by the embodiment of the invention is not used, and the front-section response is smaller; in fig. 5, the straight line with an arrow is the frequency response curve of the vibration device after the low-frequency vibration compensation method provided by the embodiment of the invention is used, so that the acceleration response is obviously compensated and enhanced in the previous response time.
According to the low-frequency vibration sense compensation method provided by the embodiment of the invention, after the vibration device receives the vibration command, the vibration device responds to the vibration command, the period and the modification on the waveform peak value are made on the basis of the original vibration signal for driving the vibration device to vibrate, the adjusted vibration sense compensation signal is obtained, when the vibration device is driven by the signal, the vibrator of the vibration device can collide with the shell to generate a larger acceleration response, and when the peak period of the original vibration signal is n, the target period of the vibration sense compensation signal is n multiplied by k, so that the acceleration response of the vibration device is improved on the premise of not improving the frequency of the signal, and the touch sense effect generated by the vibration device under the low-frequency condition is improved.
