In the embodiment of the present application, the piezoelectric capacitor array 12 includes a plurality of piezoelectric capacitors 121. The piezoelectric capacitor 121 is a capacitor having a piezoelectric effect.

In the present embodiment, the piezoelectric capacitor 121 has a piezoelectric property, and contracts or expands when an alternating voltage is applied. Specifically, when a voltage that changes alternately is applied to the piezoelectric capacitor 121, the piezoelectric capacitor 121 is deformed by bending up and down. In short, the capacitor is driven to vibrate up and down by continuously changing voltage. Generally, as shown in fig. 2, the piezoelectric effect is proportional to the electric field intensity, the applied voltage is constant, and the thinner the medium is, the stronger the piezoelectric effect is; therefore, the thinner capacitor is adopted, the more obvious deformation effect is generated, a thinner panel can be made, and the terminal can be thinned.

It can be understood that, as shown in fig. 3, when the piezoelectric capacitor 121 is fixed on the panel, the panel is driven to vibrate together due to the vibration of the piezoelectric capacitor 121. When the amplitude of a single piezoelectric capacitor 121 is low, a plurality of piezoelectric capacitors 121 (capacitor arrays) can be driven to vibrate, so that a good vibration effect is achieved.

Specifically, the piezoelectric capacitors 121 are arranged to form the piezoelectric capacitor array 12 and fixed on the panel, and when the piezoelectric capacitors 121 are bent and deformed up and down, the panel is also deformed because the piezoelectric capacitors are fixed on the panel, that is, the panel is driven by the vibration of the piezoelectric capacitors 121 to vibrate together.

In a possible embodiment, the electronic device further includes: and a vibration panel 14 disposed at the rear of the screen 11. It is understood that the vibrating panel 14 may be attached to the back of the full screen module.

In a possible embodiment, as shown in fig. 4, the screen 11 includes a touch screen and a vibration panel 14 disposed on the back of the touch screen. It is understood that the vibrating panel and the screen module can be assembled together to form a common screen module.

In a possible embodiment, as shown in fig. 5, the vibrating panel 14 further comprises: row control lines 15 and column control lines 16; the touch feedback means 17 are connected to the row control lines 15 and the column control lines 16.

Wherein, the row control line is respectively connected with the first end of each piezoelectric capacitor 121 in the piezoelectric capacitor array 12; the column control lines are respectively connected to the second ends of the piezoelectric capacitors 121 in the piezoelectric capacitor array 12.

In the embodiment of the present application, as shown in fig. 6, the vibration panel 14 further includes a filling medium 18, the filling medium plays a role of fixing the piezoelectric capacitors and the row and column control lines, all the piezoelectric capacitors can be uniformly distributed on the vibration panel, and the piezoelectric capacitors are wrapped by the filling medium of the vibration panel, so that the piezoelectric capacitors can be protected from the risk of capacitance damage caused by an excessive vibration amplitude.

In the electronic device provided by the embodiment of the application, the screen of the electronic device is correspondingly provided with the piezoelectric capacitor array, and after the electronic device receives a first touch input of a user to a first touch area of the screen, the electronic device can control the first piezoelectric capacitor corresponding to the first area in the piezoelectric capacitor array to vibrate. Therefore, the piezoelectric capacitor array is correspondingly arranged on the screen of the electronic equipment, so that a user can obtain different touch feedback through different touch areas of the touch screen, the flexibility of vibration feedback of the electronic equipment can be improved, and the operation experience is improved.

As shown in fig. 7, the touch feedback method provided in the embodiments of the present application may include the following steps 201 and 202:

step 201: a first touch input of a user to a first touch area of a screen of an electronic device is received.

In the embodiment of the present application, the touch input includes a click input, a slide input, a press input, and the like of the first touch area by the user. The click input in the embodiment of the invention can be single click input, double click input or click input of any number of times, and the click input can also be long-time press input or short-time press input.

In this embodiment of the application, the first touch input may be a touch input of a user to content displayed in the first touch area. Illustratively, the content displayed in the first touch area includes content such as virtual buttons, controls, icons, text, pictures, videos, and the like.

In this embodiment of the application, the first touch area may be any touch area in a screen of the electronic device.

In an embodiment of the present invention, the first touch area may be one or more touch areas. That is, the user can touch a plurality of touch areas simultaneously to trigger corresponding touch feedback.

Optionally, in this embodiment of the application, the step 201 of "receiving a first touch input of the user to the first touch area of the screen" may include the step 201 a:

step 201 a: a first touch input of a user to a first virtual key on a first touch area of a screen of an electronic device is received.

In one possible embodiment, the first virtual key may include one or more virtual keys. That is, the first touch area may include a plurality of virtual keys, for example, assuming that the first touch area includes a touch area 1 and a touch area 2, the first virtual keys may include a virtual key 1 displayed in the touch area 1 and a virtual key 2 displayed in the touch area 2.

In one possible embodiment, in a case that a first interface of a first application is displayed, a touch feedback device receives a first input of a first virtual key of the first interface from a user. The first touch area may be: and the touch area is located by a first virtual key in a first interface corresponding to the first application.

Example 1: as shown in fig. 8, after the electronic device starts the "game" APP, a game interface 31 of the "game" APP is displayed, and a "direction" virtual key 32 and a "function" virtual key 33 are displayed in the game interface, where the "function" virtual key includes four skill virtual keys, which are "general skill" virtual keys: namely a "skill 1" virtual key 33a, a "skill 2" virtual key 33b, a "skill 3" virtual key 33c, and an "ultimate skill" virtual key 33 d. Thus, when the user wants to release the ultimate skill, the "ultimate skill" virtual key 33d (i.e., the first touch input described above) can be touched.

Step 202: and responding to the first touch input, and controlling the first piezoelectric capacitor to vibrate.

Wherein, the first piezoelectric capacitor is: and the piezoelectric capacitor array is provided with a piezoelectric capacitor corresponding to the first touch area.

In the embodiment of the present application, since the piezoelectric capacitor array is disposed corresponding to the screen of the electronic device, each touch area in the screen corresponds to at least one piezoelectric capacitor. Therefore, when a user touches a certain touch area, the touch feedback device can control at least one piezoelectric capacitor corresponding to the touch area in the capacitor array to vibrate.

In the embodiment of the present application, when a user touches a certain touch area, the touch feedback device controls the piezoelectric capacitor in the piezoelectric capacitor array corresponding to the touch area to vibrate.

For example, after the electronic device starts a certain game application, when the user touches a virtual button corresponding to a common skill, a weaker touch feedback is provided, and when the user touches a virtual button corresponding to an ultimate skill, a stronger touch feedback is provided.

Optionally, in this embodiment of the application, the step 202 of "controlling the first piezo capacitor to vibrate in response to the first touch input" may include the step 202 a:

step 202 a: and responding to the first touch input, and inputting a first control signal to the first piezoelectric capacitor so as to control the first piezoelectric capacitor to vibrate according to the first vibration parameter.

In an embodiment of the present application, the first vibration parameter includes at least one of: vibration frequency, vibration frequency and vibration duration. The vibration frequency refers to the vibration speed of the piezoelectric capacitor in unit time, the vibration frequency refers to the vibration frequency in the whole vibration feedback process, and the vibration duration refers to the vibration duration of the piezoelectric capacitor in the whole vibration feedback process.

In an embodiment of the application, the first vibration parameter is determined based on the first touch area.

It can be understood that, when a user touches different touch areas, the touch feedback device may select a vibration parameter matched with the position of the first touch area or content displayed on the first touch area, and then send a control signal corresponding to the vibration parameter to a piezoelectric capacitor corresponding to the touch area, so as to control the piezoelectric capacitor to vibrate according to the vibration parameter.

In one example, a vibration strategy may be preset. For example, the shock strategy includes: mapping relationships between different touch areas and vibration parameters in the screen, or mapping relationships between different display contents and vibration parameters.

In one example, assume that the first touch input is: and if the user touches a first virtual key on a first touch area of the screen of the electronic equipment, the first vibration parameter is a vibration parameter matched with the first virtual key. It can be understood that different virtual keys correspond to different vibration parameters, or different types of virtual keys correspond to different vibration parameters, or virtual keys for different applications correspond to different vibration parameters.

For example, in connection with the above example 1, assume that the vibration strategy preset in the "game" APP is: a vibration strategy 1, wherein the vibration frequency corresponding to the common skill virtual key is frequency 1, and the vibration frequency is 1; and 2, in the vibration strategy 2, the vibration frequency corresponding to the ultimate skill virtual key is frequency 2, and the vibration frequency is 2. If the skill 1 virtual key 33a is displayed on the first touch area pressed by the user, the touch feedback device controls the first piezoelectric capacitor to vibrate according to the vibration strategy 1.

It should be noted that the vibration frequency needs to be 20 Hz-20 KHz which can be heard by avoiding human ears, so as to avoid audible noise generated by vibration. That is, the vibration frequency is a frequency within a specific frequency range.

In an embodiment of the present application, the first control signal may be a pulse signal.

In the embodiment of the present application, different control signals (i.e., control signals with different frequencies and/or different amplitudes) are applied to the piezoelectric capacitor, so that the piezoelectric capacitor vibrates according to the vibration parameters matched with the control signals. In this manner, by controlling the amplitude or frequency of the control signal applied to the piezoelectric capacitor, the vibration intensity of the piezoelectric capacitor can be controlled. Generally, a control signal with high frequency and high amplitude can achieve a stronger vibration effect; the control signal with low frequency and low amplitude can achieve a weaker vibration effect.

For example, referring to example 1, as shown in fig. 8, the "function" virtual keys in the game interface include four different virtual keys, and the capacitances corresponding to the different virtual keys respectively adopt vibration frequencies f0, f1, f2, and f3, so that when a user touches the different virtual keys, vibration feedback with different frequencies can be sensed.

Optionally, in an embodiment of the present application, the first touch input includes: touch input of a user to a first area in the first virtual key is performed; wherein, the first vibration parameter is matched with the first area. In other words, different regions in the first virtual key correspond to different vibration parameters.

For example, the virtual key usually occupies a certain area of the display area when displayed, that is, the virtual key corresponds to a certain area of the touch area, and the touch area usually corresponds to a plurality of piezoelectric capacitors. Therefore, when a user touches different areas of the virtual key, in order to feed back corresponding vibration feedback for the user more accurately, the vibration of the piezoelectric capacitor corresponding to the touch position can be further accurately controlled based on the accurate touch position of the user in the virtual key.

For example, in connection with example 1, as shown in fig. 9, the "direction" virtual key in the game interface includes an arrow direction (dark color) area and a non-arrow direction (light color) area. Here, the piezoelectric capacitor located below the arrow direction has a control vibration frequency fa, and the other piezoelectric capacitors located below the arrow direction have a vibration frequency fb. (fa > fb). Thus, when the user touches the arrow direction area, the user can perceive strong vibration feedback, and when the user touches the non-arrow direction area, the user can perceive slight vibration feedback.

Further, the above-mentioned vibration frequency fa may be one frequency range, and the arrow direction area includes 4 azimuth areas, different azimuth areas corresponding to different frequencies within the frequency range fa. In this way, if the user touches the left area of the arrow direction area with the vibration frequency fa1, and if the user touches the right area of the arrow direction area with the vibration frequency fa2, the user can perceive different vibration feedbacks when touching different azimuth areas, thereby knowing the direction he wants to manipulate.

Optionally, in this embodiment of the application, the first piezoelectric capacitor includes N piezoelectric capacitors, where N is an integer greater than 1.

In one possible embodiment, the step 202a of inputting the first control signal to the first piezoelectric capacitor may include the step 202a 1:

step 202a 1: the first control signal is simultaneously input to the N piezoelectric capacitors.

In the embodiment of the application, when a touch vibration feedback needs to be generated in a local area, the touch feedback device sends a first control signal to the plurality of piezoelectric capacitors simultaneously to drive the piezoelectric capacitors corresponding to the touch area to vibrate together.

Optionally, in this embodiment of the application, the step 202a "inputting the first control signal to the first piezoelectric capacitor" may further include the step 203a 2:

step 203a 2: and inputting a first sub-signal to a first end of the first piezoelectric capacitor, and inputting a second sub-signal to a second end of the first piezoelectric capacitor.

The first control signal comprises a first sub-signal and a second sub-signal, and the level of the first sub-signal is opposite to that of the second sub-signal.

In the embodiment of the application, in order to improve the pressure difference change at two ends of the capacitor and improve the vibration effect, voltages with opposite positive and negative can be applied to two ends of the row and column control, so that the pressure difference at two ends of the capacitor is larger, and the vibration effect is stronger.

In the embodiment of the application, the piezoelectric capacitor can be controlled to vibrate at different frequencies by sending control signals with different frequencies and/or different amplitudes to the piezoelectric capacitor. As shown in fig. 10 (a), a control signal having a higher frequency and a larger amplitude may be applied to the piezoelectric capacitor, and as shown in fig. 10 (b), a control signal having a lower frequency and a smaller amplitude may be applied to the piezoelectric capacitor,

in the embodiment of the present application, on the basis of sending control signals with different frequencies and/or different amplitudes to the piezoelectric capacitor, the voltage difference between two ends of the piezoelectric capacitor can also be changed. Specifically, a voltage with a positive polarity is applied to one end of the piezoelectric capacitor, and a voltage with a negative polarity is applied to the other end of the piezoelectric capacitor, so that the potential difference (voltage difference) between the two ends of the piezoelectric capacitor is larger. Therefore, the vibration effect difference can be controlled through the amplitude and the frequency of the control signal, the vibration intensity of the piezoelectric capacitor can be further controlled through the level output by the control signal, and finally different vibration effects of different touch areas are achieved.

In the touch feedback method provided in the embodiment of the present application, a piezoelectric capacitor array is correspondingly disposed on a screen of an electronic device, and after a first touch input of a user to a first touch area of the screen is received, a vibration of a first piezoelectric capacitor corresponding to the first area in the piezoelectric capacitor array can be controlled.
