[0039] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] An embodiment of the present invention provides a vibration detection device for detecting vibration characteristic parameters of a touch feedback button.

[0041] In this embodiment, referring to Figure 1 The vibration detection device includes a test module 1 and an analysis module 2, and the analysis module 2 is connected to the test module 1. The analysis module 2 can be connected to the touch feedback button to be tested.

[0042] The test module 1 is a piezoelectric ceramic sheet, and a detection area is set in the middle of the piezoelectric ceramic sheet for placing the touch feedback button to be tested. The touch feedback button includes piezoelectric ceramics.

[0043] Analysis module 2 includes a processor 1001 (e.g., a CPU), memory 1002, a timer 1003, and the like. The components of analysis module 2 are connected via a communication bus. Memory 1002 can be high-speed RAM or non-volatile memory, such as disk storage. Memory 1002 can also optionally be a storage device independent of processor 1001.

[0044] Those skilled in the art will understand that Figure 1 The device structure shown in the figure does not constitute a limitation of the device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0045] like Figure 1 As shown, the memory 1002 as a storage medium may include a detection program for touch feedback keys. Figure 1 In the device shown, the processor 1001 can be used to call the touch feedback button detection program stored in the memory 1002 and execute the relevant steps of the touch feedback button detection method in the following embodiments.

[0046] An embodiment of the present invention further provides a method for detecting a touch feedback button, which is applied to the above-mentioned vibration detection device.

[0047] Reference Figure 2 , an embodiment of a method for detecting a touch feedback button of the present application is proposed. In this embodiment, the method for detecting a touch feedback button includes:

[0048] Step S10, obtaining an output electrical signal of the piezoelectric ceramic when the touch feedback button is in a vibrating state;

[0049] Inputting a preset electrical signal into the piezoelectric ceramic of the touch feedback button drives the piezoelectric ceramic to vibrate. The vibration of the piezoelectric ceramic drives the overall vibration of the touch feedback button. In this state, the electrical signal output by the piezoelectric ceramic is detected as the output electrical signal here.

[0050] Specifically, the above analysis module can be connected to the piezoelectric ceramic in the touch feedback button, and step S10 is performed when the two are in a connected state.

[0051] Among them, the volume of the touch feedback button can be obtained, and the target duration can be determined based on the volume. Different volumes correspond to different target durations. When the duration of the preset electrical signal input to the touch feedback button reaches the preset duration, the electrical signal output by the piezoelectric ceramic is detected as the output electrical signal here.

[0052] In this embodiment, the output electrical signal is an output voltage. In other embodiments, the output electrical signal may be an output current or an output power.

[0053] Step S20: determining the vibration characteristic parameters of the touch feedback button according to the output electrical signal.

[0054] The vibration characteristic parameter is specifically a parameter that characterizes the vibration characteristics of the touch feedback button. The vibration characteristic parameter may include vibration amplitude and / or vibration frequency, etc.

[0055] Different output electrical signals correspond to different vibration characteristic parameters. Specifically, a correspondence between the output electrical signal and the vibration characteristic parameters can be pre-established. This correspondence can include a calculation relationship, a mapping relationship, or other forms. Based on this correspondence, the vibration characteristic parameters corresponding to the current output electrical signal can be determined. For example, the output electrical signal can be substituted into a preset formula to calculate the vibration characteristic parameters; in another example, the vibration characteristic parameters can be obtained by searching a pre-set mapping table based on the output electrical signal.

[0056] After obtaining the vibration characteristic parameters, the vibration characteristic parameters may be further outputted, performance evaluation parameters of the touch feedback key may be determined based on the vibration characteristic parameters, and performance debugging of the touch feedback key may be performed based on the vibration characteristic parameters.

[0057] An embodiment of the present invention proposes a method for detecting a touch feedback button. The method detects an output electrical signal of a piezoelectric ceramic of the touch feedback button when the touch feedback button is in a vibrating state, and determines the vibration characteristic parameters of the touch feedback button based on the output electrical signal. Based on this, an electrical signal detection device can be used during the production process of electronic equipment to effectively detect the vibration characteristics of the touch feedback button. The electrical signal detection device is easy to obtain and the detection process is simple, thereby achieving simple and effective detection of the vibration effect of the touch feedback button, which is beneficial to improving the performance of the electronic equipment.

[0058] Furthermore, based on the above embodiment, another embodiment of the detection method of the touch feedback button of the present application is proposed. In this embodiment, referring to Figure 3 , the vibration characteristic parameter includes vibration amplitude, and the step S20 includes:

[0059] Step S21, obtaining a preset corresponding relationship between the deformation amount of the touch feedback button and the output electrical signal;

[0060] The preset corresponding relationship here can be a corresponding relationship obtained and stored through experimental testing. The preset corresponding relationship can include a preset relationship expression, a preset mapping table, and the like.

[0061] The preset correspondence relationship may be a fixed relationship set in advance, or may be one of multiple preset relationships selected based on the actual application scenario of the touch feedback button. For example, one of multiple relationships may be determined as the preset correspondence relationship based on the touch surface area of ​​the touch feedback button, one of multiple relationships may be determined as the preset correspondence relationship based on the type of electronic device in which the touch feedback button is installed, or one of multiple relationships may be determined as the preset correspondence relationship based on the thickness of a structural member in the touch feedback button connected to the piezoelectric ceramic.

[0062] Step S22: determining the deformation amount corresponding to the output electrical signal as the vibration amplitude according to the preset corresponding relationship.

[0063] When the preset corresponding relationship is a preset relational expression between the output electrical signal and the deformation amount, the output electrical signal can be substituted into the preset relational expression to calculate the deformation amount as the vibration amplitude.

[0064] When the preset corresponding relationship is a preset mapping table between the output electrical signal and the deformation amount, the preset mapping table can be queried through the output electrical signal, and the deformation amount in the preset mapping table that matches the output electrical signal is used as the vibration amplitude.

[0065] In this embodiment, by presetting the corresponding relationship between the deformation amount and the output signal, the amplitude of the touch feedback button can be accurately determined based on the output electrical signal, thereby effectively improving the accuracy of the vibration effect test of the touch feedback button.

[0066] Furthermore, based on the above embodiment, another embodiment of the detection method of the touch feedback button of the present application is proposed. In this embodiment, referring to Figure 4 , before step S10, further comprising:

[0067] Step S01, when a standard component corresponding to the touch feedback button is fixed to the middle area of ​​the piezoelectric ceramic sheet, detecting test electrical signals outputted by the piezoelectric ceramic sheet respectively under multiple preset deformation amounts of the standard component to obtain multiple test electrical signals;

[0068] Specifically, the standard part is a touch feedback button that has the same hardware specifications as the touch feedback button to be tested and is used to establish a preset corresponding relationship.

[0069] A detection area can be set in the central area of ​​the piezoelectric ceramic plate, and the standard part is placed in the detection area.

[0070] Multiple different preset pressures can be applied to the piezoelectric ceramic piece on the surface of the standard piece to make the standard part reach multiple preset deformation variables. The detection area is affected by the deformation, which will cause the output electrical signal to change. In the process of reaching each preset deformation variable or at the moment of reaching each preset deformation variable, the electrical signal output by the piezoelectric ceramic piece is collected as the corresponding test electrical signal, and a test electrical signal is obtained for each preset deformation variable.

[0071] For example, when the standard part is subjected to a deformation of 10 microns, the corresponding voltage collected from the output of the piezoelectric ceramic piece is A; when the standard part is subjected to a deformation of 15 microns, the corresponding voltage collected from the output of the piezoelectric ceramic piece is B; when the standard part is subjected to a deformation of 20 microns, the corresponding voltage collected from the output of the piezoelectric ceramic piece is C... and so on. Based on these data, a preset correspondence can be established.

[0072] Step S02: establishing the preset corresponding relationship according to the plurality of preset deformation amounts and the plurality of test electrical signals.

[0073] Specifically, a functional relationship obtained by fitting multiple preset deformation variables and multiple test electrical signals can be used as the preset corresponding relationship. The functional relationship can be a linear relationship or a nonlinear relationship.

[0074] Alternatively, multiple deformation intervals and the electrical signal value corresponding to each deformation interval may be determined based on multiple preset deformation intervals and multiple test electrical signals, and the mapping relationship between the deformation intervals and the electrical signal values ​​may be used as the preset corresponding relationship here.

[0075] In this embodiment, the deformation of the touch feedback button can be fed back in the test electrical signal output from the piezoelectric ceramic piece. The preset correspondence relationship established based on this can accurately reflect the relationship between the deformation occurring during the vibration of the touch feedback button and the electrical signal output by the piezoelectric ceramic, thereby ensuring the accuracy of the vibration characteristic parameters of the touch feedback button obtained based on the preset correspondence relationship.

[0076] Furthermore, in this embodiment, the step of detecting the test electrical signals outputted by the piezoelectric ceramic piece respectively under a plurality of preset deformation amounts of the standard part, before obtaining the plurality of test electrical signals, also includes: obtaining the contact area between the standard part and the piezoelectric ceramic piece; and determining the plurality of preset deformation amounts based on the contact area.

[0077] Different contact areas correspond to different preset deformation variables with different values. Specifically, a correspondence between the contact area and the multiple preset deformation variables can be pre-established, and the multiple preset deformation variables corresponding to the current contact area can be determined based on the correspondence. Specifically, the minimum value of the multiple preset deformation variables can be determined based on the contact area, and the multiple preset deformation variables can be determined based on the minimum value, the preset number corresponding to the multiple preset deformation variables, and the deviation between two adjacent preset deformation variables in the multiple preset deformation variables. Alternatively, multiple deformation variable sets can be pre-set, each of which includes multiple deformation variables, and different deformation variable sets correspond to different contact area numerical ranges. The deformation variable set corresponding to the range in which the current contact area falls is used as the target set, and the multiple deformation variables in the target set are used as the multiple preset deformation variables here.

[0078] In this embodiment, multiple preset deformation amounts are determined based on the contact area between the standard part and the piezoelectric ceramic sheet to determine the above-mentioned preset corresponding relationship, which is conducive to ensuring the accurate improvement of the vibration effect of the touch feedback button represented by the vibration characteristic parameters of the touch feedback button determined based on the preset corresponding relationship.

[0079] Furthermore, in this embodiment, the step of determining the multiple preset deformation variables based on the contact area includes: determining a ratio of the contact area to a preset area; and determining the multiple preset deformation variables based on the ratio; wherein the preset area is the area of ​​the surface of the piezoelectric ceramic plate used to secure the standard component. Different ratios correspond to different multiple preset deformation variables. The ratio is negatively correlated with the minimum value of the multiple preset deformation variables. That is, the smaller the proportion of the contact area to the preset area, the larger the minimum value of the multiple preset deformation variables. Conversely, the larger the proportion of the contact area to the preset area, the smaller the minimum value of the multiple preset deformation variables.

[0080] In this embodiment, multiple preset deformation amounts are determined based on the ratio of the contact area to the preset area, which helps to avoid the situation where the deformation is too small when the ratio is too small, resulting in the output test electrical signal being too small and causing detection errors, thereby further improving the accuracy of the determined preset correspondence.

[0081] Furthermore, based on any of the above embodiments, another embodiment of the detection method of the touch feedback button of the present application is proposed. In this embodiment, referring to Figure 5 After step S20, the method further includes:

[0082] Step S30 , adjusting the driving electrical signal of the piezoelectric ceramic according to the vibration characteristic parameter and a target vibration parameter range corresponding to the target tactile sensation, until the adjusted vibration characteristic parameter is within the target vibration parameter range.

[0083] The target tactile sensation is a preset tactile sensation that satisfies the user's needs when contacting the surface of a touch feedback button. The target vibration parameter range can be a preset fixed range, a range determined based on user-configured parameters, or a range determined based on the key press detected by the current touch feedback button.

[0084] Specifically, the adjustment parameters (adjustment direction and / or adjustment amplitude, etc.) of the driving electrical signal can be determined based on the quantitative relationship and / or size relationship between the vibration characteristic parameters and the target vibration parameter range. The driving electrical signal of the piezoelectric ceramic can be adjusted according to the adjustment parameters. After adjustment, the process can return to step S10 until the vibration characteristic parameters are within the target vibration range.

[0085] Specifically, when the vibration characteristic parameter is greater than the upper limit value of the target vibration parameter interval, the driving electrical signal is reduced until the vibration characteristic parameter after debugging is within the target vibration parameter interval; when the vibration characteristic parameter is less than the lower limit value of the target vibration parameter interval, the driving electrical signal is increased until the vibration characteristic parameter after debugging is within the target vibration parameter interval. Specifically, when reducing or increasing the driving electrical signal, it can be adjusted according to a pre-set fixed adjustment amplitude, or a first difference between the vibration characteristic parameter and the upper limit value can be determined, a first adjustment amplitude is determined based on the first difference, the driving electrical signal is reduced based on the first adjustment amplitude, a second difference between the lower limit value and the vibration characteristic parameter is determined, a second adjustment amplitude is determined based on the second difference, and the driving electrical signal is increased based on the second adjustment amplitude.

[0086] In this embodiment, the driving electrical signal is a driving voltage input to the piezoelectric ceramic to cause it to vibrate. In other embodiments, the driving electrical signal may also be a driving current or driving power input to the piezoelectric ceramic to cause it to vibrate.

[0087] In this embodiment, through the above-mentioned method, it can be achieved that the tactile feeling of the touch feedback button can accurately meet the tactile feeling requirements of the user during the piezoelectric ceramic vibration feedback process.

[0088] In addition, an embodiment of the present invention further provides a storage medium storing a touch feedback button detection program. When the touch feedback button detection program is executed by a processor, the relevant steps of any embodiment of the touch feedback button detection method as described above are implemented.

[0092] Further, refer to Figure 6 The vibration detection device also includes a debugging module 300, which is used to debug the driving electrical signal of the piezoelectric ceramic according to the vibration characteristic parameter and the target vibration parameter range corresponding to the target tactile sensation, until the vibration characteristic parameter after debugging is within the target vibration parameter range.
