Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structural diagram of a keyboard according to an embodiment of the present invention, where the keyboard can be applied to an electronic device, such as a notebook computer, a computer, and the like.
The touch panel 11 includes a plurality of character areas, and a character area corresponds to at least one character and/or at least one touch operation area.
Characters may include letters, numbers, words and symbols used in computers, including: 1. 2, 3, …, A, B, C, -! # … … - (-) -etc.
The touch operation region may include a touch pad, and a touch pad (TouchPad) is an input region for moving a cursor by a sliding operation of a finger on a smooth touch pad.
A plurality of motors 12, wherein at least one of the plurality of motors 12 is a piezo ceramic motor.
Preferably, each motor is a piezo-ceramic motor. Because the response time of the piezoelectric ceramic motor is short, after a user touches and presses a target character area, the piezoelectric ceramic motor can quickly respond, the touch, namely vibration, feeling is brought to the user, and time delay is avoided; the vibration of the piezoelectric ceramic motor is localized, i.e. the vibration is concentrated in the area where the piezoelectric ceramic motor is located. When a plurality of motors 12 are arranged in the keyboard, as long as the positions are properly arranged, when a user touches a certain character region, the effect that only the character region vibrates is generated, so that the user experience is better.
And the controller 13 is used for controlling at least one motor to generate vibration according to a preset control strategy when detecting that the target character area is touched and pressed.
The vibration waveform generated by the at least one motor has a first vibration characteristic in the target character area.
The first vibration characteristic includes:
the amplitude of the vibration waveform generated by the at least one motor is maximum in the target character area;
or,
the amplitude of the vibration waveform generated by the at least one motor is not zero only in the target character region.
In order to realize that the target character area has the first vibration characteristic, when the controller 13 detects that the target character area is touched, and controls at least one motor to generate vibration according to a preset control strategy, the controller is specifically configured to:
when the target character area is detected to be touched, controlling at least one first motor in the at least one motor to start vibrating at a first frequency at a first time according to the preset control strategy; controlling at least one second motor of the at least one motor to begin vibrating at a second frequency at a second time.
The first frequency and the second frequency may be the same or different; it is understood that the controller 13 controls at least one third motor of the at least one motor to start shaking at a third frequency at a third time according to a preset control strategy; and so on.
In summary, the controller 13 may control the vibration starting time and/or the vibration frequency and/or the vibration maximum amplitude of each of the at least one motor to be different as long as the target character region having the first vibration characteristic can be achieved.
Because the power of each motor may be different, and the frequency and the maximum amplitude of the waveform generated by the vibration of each motor may be different, the controller 13 may control the vibration starting time of each motor, so that the waveform of each motor has the first vibration characteristic in the target character region after being superimposed.
In order to achieve that the target character area has the first vibration characteristic, when the controller 13 detects that the target character area is touched, and controls at least one motor to generate vibration according to a preset control strategy, the controller may be further configured to:
and when the target character area is detected to be touched and pressed, controlling at least one motor corresponding to the target character area to generate vibration according to the preset control strategy.
The attack time and/or vibration frequency and/or maximum amplitude of at least one motor that causes the respective character region to have the respective vibration characteristic may be set in advance; and when the target character area is touched, controlling the corresponding motor to vibrate. Thus, the preset control strategy includes: and determining the at least one motor corresponding to the target character area according to the preset corresponding relation between each character area and the motor.
It can be understood that the vibrations of the motors have a certain locality, the vibrations of the motors farther from the target character region do not bring an effect to the target character region, and although the vibrations of the motors farther from the target character region do not bring an obvious effect to the target character region, the vibrations of the motors farther from the target character region can counteract the "aftershocks" of the motors closer to the target character region. Thus, the preset control strategy may include: determining the at least one motor based on a distance between the target character area and each motor.
For example, at least one first motor may be determined from the at least one motor and at least one second motor may be determined from the at least one motor based on a distance between the target character area and each motor.
In general, the vibration intensity is proportional to the distance between the target character area and the motor.
Preferably, there is a separate control circuit for each motor.
The vibration intensity corresponding to each character region may be different, and therefore, the preset control strategy includes: determining target vibration intensity corresponding to the target character area according to preset corresponding relation between each character area and the vibration intensity; and determining the at least one motor from the plurality of motors according to the target vibration intensity.
Each character area in the keyboard corresponds to at least one motor, and the at least one motor corresponding to each character area is arranged below the corresponding character area. Or at least two character areas in the keyboard correspond to one motor.
Each character area corresponds to at least one motor and comprises the following conditions:
each character area corresponds to one motor; or, each character area corresponds to two motors; …, respectively; or, each character in each character area corresponds to one motor.
It is assumed that the keyboard includes 6 character areas, specifically as shown in fig. 2, each character area corresponds to one motor, and the 6 character areas are a character area 1, a character area 2, a character area 3, a character area 4, a character area 5, and a character area 6, respectively; the character area 1 corresponds to the motor 1, the character area 2 corresponds to the motor 2, the character area 3 corresponds to the motor 3, the character area 4 corresponds to the motor 4, the character area 5 corresponds to the motor 5, and the character area 6 corresponds to the motor 6.
If the target character area "a" in the character area 1 is touched by the user, as shown by the black square in fig. 2, the controller 13 may control at least one motor to vibrate, so that the target character area "a" has the first vibration characteristic.
For example, the controller 13 may control the motors 1, 2, 4 and 5 to vibrate, and waveforms generated by the vibrations of the motors 1, 2, 4 and 5 are superimposed on each other so that the amplitude is maximized in the target character region "a", i.e., the region indicated by the black square in fig. 2. The user is given the feeling that the target character area is successfully touched as 'A'.
If each character area corresponds to a motor and the target character area in the character area 1 touched by the user is "a", the motor corresponding to the target character area "a" generates vibration.
In the embodiment of the invention, at least one of the motors is a piezoelectric ceramic motor, and preferably all the motors are piezoelectric ceramic motors, because the response time of the piezoelectric ceramic motors is short, the piezoelectric ceramic motors can quickly respond after a user touches and presses a target character area, and the vibration sense of the piezoelectric ceramic motors is localized, namely the vibration sense is concentrated in the target character area, so that the user experience is better. Fig. 3 is a schematic diagram illustrating a piezoelectric ceramic motor, a rotor motor, and a linear motor according to an embodiment of the present invention.
In fig. 3, the touch force versus response time curves for ERM (eccentric rotor motor) and LRA (linear resonant motor) are almost the same; and the response time of Piezo (piezoelectric ceramic motor) is far shorter than that of ERM and LRA under the same touch force. In a preferred embodiment, the Piezo ceramic motor has a response time of less than 1 ms.
In summary, the sensitivity of Piezo ceramic motors is much higher for Piezo ceramic motors than for ERM and LRA motors.
By adopting the piezoelectric ceramic motor, after a user touches the target character area, the piezoelectric ceramic motor can quickly respond within 1ms and enter a vibration state, so that the user can feel that the user vibrates immediately after touching the target character area.
As shown in fig. 4, the external structure of the piezoelectric ceramic motor is shown. Fig. 5 is a schematic view of the internal vibration of the piezoceramic motor.
The piezoceramic motor switches between a relaxed state and a deformed state during vibration.
It can be understood that when different character areas are touched, the vibration characteristics of the vibration waveform generated by the corresponding motor in the corresponding character areas are controlled to be different according to the preset control strategy.
The different vibration characteristics may refer to one or more of different amplitudes, different positions of the vibrations, and different frequencies of the vibrations.
If the user touches a target character area and only the target character area vibrates, the vibration characteristics may not include: the location of the vibration is different because the different character areas are located at different positions.
If a user touches a target character area, the motor may drive the surrounding area to vibrate in the vibration process, so that the amplitude of the target character area is maximized or the vibration frequency is maximized by using the characteristics of the waveform.
