Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
Suffixes such as "module", "part", or "unit" used to denote elements are used herein only for the convenience of description of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.
In the following description, the serial numbers of the embodiments of the invention are merely for description and do not represent the merits of the embodiments.
Example one
As shown in fig. 1, an embodiment of the present invention provides a low frequency vibration sense compensation method, which is improved based on a driving signal of a vibration device to improve a low frequency vibration sense of the vibration device, and the method includes, but is not limited to, the following steps:
s101, after the 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 start vibration.
In the above step S101, the vibration instruction may be an instruction that the user operates the electronic device to cause the electronic device to transmit to the vibration device, such as a pressing instruction on a display screen of the electronic device.
In a specific application, the vibration device should generate vibration immediately in response to an operation of a user on the electronic device, but in the embodiment of the present invention, before the vibration device responds to the vibration instruction, the vibration device further executes step S101 and step S102, and when the vibration device responds to the vibration instruction, the vibration device executes step S103, and finally generates a strong vibration sense.
In a specific application, the short signal for driving the vibration device to vibrate is divided into an acceleration section signal and a braking section signal, and the initial value of the acceleration section signal is actually a very regular sinusoidal signal, i.e. the original vibration signal in step S101.
And S102, setting a starting oscillation compensation signal with a target period according to the peak period of the original oscillation signal.
In the above step S102, the original vibration signal may be a sinusoidal signal, the value of the peak period of which is substantially the same as the value of the function period of which, and the waveform of the start-up compensation signal set according to the original vibration signal should be the same as or similar to the original vibration signal.
The embodiment of the present invention further shows a detailed implementation manner of the step S102, which includes:
setting the target period to be integral multiple of the peak period of the original vibration signal, and setting each target period of the oscillation starting compensation signal to comprise a voltage driving period and a no-signal output period.
Wherein, in the voltage driving period, a peak time point of the oscillation starting compensation signal coincides with a peak time point of the original oscillation signal;
wherein the vibration device does not receive a signal in the no-signal output period.
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 time 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 target period is equal to
The duration of the no-signal output period is
When the target period of the oscillation starting compensation signal is nxk and k is 1, the duration of the voltage drive output period in one target period is
The duration of the no-signal output period is
As shown in fig. 2 and fig. 3, the embodiments of the present invention further show the start oscillation compensation signal with the target period set according to the peak period of the original oscillation signal when k is 1 and k is 2, respectively:
the upper half line in fig. 2 and 3 represents an original vibration signal, the lower half line in 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 indicated 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 indicated 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 time point of the original vibration signal. In a target period, if the original vibration signal has a plurality of waveform peaks and the oscillation-starting compensation signal still has one waveform peak, the waveform peak of the oscillation-starting compensation signal still coincides with a peak time point of the original vibration signal, that is, only one waveform peak of the oscillation-starting compensation signal is included in one target period and is in the voltage driving period.
And S103, enabling the vibration device to respond to the vibration instruction, driving the vibration device through the oscillation starting compensation signal, and adjusting the waveform peak value of the oscillation starting compensation signal so as to enable the vibrator of the vibration device to impact the shell.
The vibrator of the vibration device collides with the shell and is used for compensating the low-frequency vibration sense of the vibration device;
when the peak period of the original vibration signal is n, the target period of the oscillation starting compensation signal is n × k, and the impact frequency of the vibrator of the vibration device and the shell is n
k 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 thereof is in a multiple relationship, and it can be known from the above that the frequency of the oscillation starting compensation signal is always smaller than the frequency of the original vibration signal, so that the vibration inductance is not improved by increasing the signal frequency in the embodiment of the present invention, and the vibration inductance compensation method provided in the embodiment of the present invention can be applied under the low frequency condition.
In step S103, the adjusted start-up compensation signal is based on the original vibration signal, and the period and the peak value of the waveform in the period are changed, so that when the vibration device is driven by the adjusted start-up compensation signal, the input of the original vibration signal is not blocked, and another driving signal is not input to the vibration device.
In a specific application, the impact frequency of the vibrator of the vibration device and the shell is the vibration frequency which can be felt by a user, if the target period of the vibration starting compensation signal is 0.1s, the user has vibration feeling every 0.1s, that is, the user has vibration feeling experience with the frequency of 10 Hz.
In the embodiment of the present invention, the waveform peak of the oscillation starting compensation signal corresponds to the vibration sense intensity, the target period of the oscillation starting compensation signal corresponds to the vibration sense frequency, and the user can feel the vibration sense experience at different frequencies by adjusting the target period.
The embodiment of the present invention further shows a detailed implementation manner of step S103, which includes:
s1031, obtaining a standard waveform peak value corresponding to the vibration sensation requirement;
s1032, calculating a target input voltage required at the peak time point of the oscillation starting compensation signal according to the standard waveform peak;
s1033, setting a pulse voltage according to the target input voltage and the target period;
s1034, inputting the oscillation starting compensation signal and the pulse voltage into the vibration device so as to enable the vibrator of the vibration device to impact 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 adjusted start-up compensation signal, so that the waveform peak value of the start-up compensation signal reaches the standard waveform peak value.
In the above steps S1031 to S1034, each waveform peak of the oscillation starting compensation signal is increased by the periodic pulse voltage to reach the standard waveform peak corresponding to the vibration sensing requirement.
In specific application, the standard waveform peak value corresponding to the vibration sensing requirement indicates a voltage value corresponding to the standard waveform peak value, so that the vibrator of the vibration device can 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 embodiments of the present invention further exemplarily show a waveform 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 start compensation signal after the waveform peak value is adjusted has a higher waveform peak value, which indicates that the corresponding voltage value can make the vibrator of the vibration device impact the housing.
In fig. 5, the curve is a frequency response curve of the vibration device when the low frequency vibration sense compensation method provided by the embodiment of the invention is not used, and it can be seen that the front-stage response is small; in fig. 5, the straight line with arrows is the frequency response curve of the vibration device after the low-frequency vibration sense compensation method provided by the embodiment of the invention is used, and it can be seen that the acceleration response is obviously compensated and enhanced in the response time of the previous period.
In the low-frequency vibration sense compensation method provided by the embodiment of the invention, after the vibration device receives the vibration instruction and before responding to the vibration instruction, the original vibration signal for driving the vibration device to start vibration is taken as the basis, the period and the waveform peak value are modified to obtain the adjusted vibration starting compensation signal, when the vibration device is driven, the vibrator of the vibration device can be collided 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 starting compensation signal is n × k.

It can be seen that 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 relation, and it can be known from the above that the frequency of the oscillation starting compensation signal is always smaller than the frequency of the original vibration signal, so that the vibration sense is not improved by increasing the signal frequency in the embodiment of the present invention, and the vibration sense compensation method provided in the embodiment of the present invention can be applied under the low-frequency condition.
