[0002] With the development of technology, the structure and functions of terminal devices such as mobile phones are updated faster and faster.

[0081] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0082] In the related art, the ways to obtain the vibration amount of the rear shell of a terminal device include:

[0083] First, the subjective feeling of the tester. Second, detecting the amplitude of a single point on the rear shell of the terminal device through an instrument.

[0084] In the ways in the related art, the following technical problems exist:

[0085] In the first method, the subjective human perception cannot quantitatively give a quantitative detection result, and the vibration amount still cannot be intuitively obtained. In the second method, the measurement of the vibration data at a single point cannot accurately and comprehensively reflect the vibration amount of the entire rear shell. Moreover, the resonance frequencies of the mobile phone back covers made of different materials are different, and the frequencies at which the maximum amplitudes occur are also different. The vibration perception coefficients of the human hand for different frequencies are also different. Coupled with the different usage habits and ways of holding the mobile phone of different users, the single-point vibration test results often show inconsistent phenomena with the subjective perception.

[0086] Therefore, in the related art, there is still a lack of a method for accurately obtaining the vibration amount.

[0087] In the embodiments of the present disclosure, a method for determining the vibration amount is proposed. The method includes: obtaining the current vibration data of the housing of the terminal device; wherein, the current vibration data includes: the current vibration frequency and the current amplitude of each of a plurality of test areas. The current vibration frequency is the frequency of the currently played audio in the terminal device speaker, and the plurality of test areas are evenly distributed on the housing of the terminal device. Determine the perception coefficient corresponding to the current vibration frequency, and the perception coefficient is used to characterize the degree of human hand perception of vibration. Determine the vibration amount of the housing according to the current vibration data and the perception coefficient. Using the method of the present disclosure, the vibration conditions of all areas of the housing can be fully investigated, and the human hand's perception of vibration can be investigated. Based on multi-dimensional factors, a more accurate vibration amount can be obtained, and the obtained vibration amount can more accurately characterize the vibration amount of the housing.

[0088] In an exemplary embodiment, the method for determining the vibration amount in this embodiment can be applied to a terminal device, such as a preset application of the terminal device. The terminal device can be an electronic device such as a mobile phone, a tablet computer, or a laptop computer.

[0089] As Figure 1 shown, the method of this embodiment may include the following steps:

[0090] S110. Obtain the current vibration data of the housing of the terminal device.

[0091] S120. Determine the perception coefficient corresponding to the current vibration frequency.

[0092] S130. Determine the vibration amount of the housing according to the current vibration data and the perception coefficient.

[0093] Among them, in step S110, the current vibration data includes: the current vibration frequency and the current amplitude of each of a plurality of test areas.

[0094] In this step, the vibration of the housing of the terminal device is related to the audio or sound source played by the speaker of the terminal device, and the current vibration frequency of the housing is the frequency of the audio currently played by the speaker of the terminal device. The current vibration frequency can be detected by an audio analyzer and sent to a preset application. Alternatively, the preset application obtains the audio or sound source information played by the current speaker and obtains the current vibration frequency.

[0095] Combined with Figure 5 As shown, in this step, a plurality of test areas 40 are evenly distributed on the housing of the terminal device. On the housing, there are a plurality of test areas 40 arranged at intervals along the length direction of the housing, and a plurality of test areas 40 arranged at intervals along the width direction of the housing. The size and shape of each test area 40 can be the same or within an error range.

[0096] The preset application can obtain the current amplitude of each test area according to the current vibration frequency. The current vibration frequency and the current amplitude are in one-to-one correspondence.

[0097] In one example, if the current vibration frequency is a fixed value, each test area 40 can determine a corresponding current amplitude.

[0098] In another example, if the current vibration frequency is a frequency range, each test area 40 can determine: the current amplitude of each current vibration frequency within this frequency range.

[0099] In step S120, the perception coefficient is used to characterize the degree of human hand perception of vibration.

[0100] For different degrees of vibration, or for vibrations at different frequencies, the user's perception is different. For example, the greater the vibration frequency, the more obvious the user's perception. In this step, according to the different frequencies, the corresponding perception coefficients can be obtained.

[0101] In step S130, according to the current vibration frequency, the current amplitude of each test area, and the perception coefficient, a more accurate housing vibration amount can be determined.

[0102] In this embodiment, the influencing factors of the speaker sound on the housing vibration amount mainly include: vibration frequency, the amplitude of each test area, and the human hand perception coefficient. Determining the vibration amount from multiple dimensions is more accurate. Moreover, the amplitudes of each test area on the housing are comprehensively considered, and the obtained value is more conducive to characterizing the vibration amount of the entire housing.

[0103] In an exemplary embodiment, the method of this embodiment further includes:

[0104] S112. Obtain the area of each test area among the multiple test areas, and the elastic coefficient of the housing.

[0105] In this step, the area of each test region and the elastic coefficient of the housing can be pre - stored in the memory of the terminal device, and the preset application calls the pre - stored area of the test region and the elastic coefficient. Alternatively, the preset application determines the area of each test region and the elastic coefficient of the housing according to the parameters input by the user in the application interface.

[0106] In this step, the areas of the test regions can be the same. After setting the test regions, the area of the test regions is stored. The elastic coefficient of the housing is related to the material of the housing. After determining the material of the housing, its elastic coefficient can be determined. The elastic coefficient can characterize the rigidity of the material. Hard materials have a higher elastic coefficient, and the elastic coefficient k 1 of the flexible material is less than the elastic coefficient k 2 of the hard material, that is: k 1 <k 2 .

[0107] In this embodiment, the vibration amount of the housing includes: the sub - vibration amount of each test region and the total vibration amount of the housing. Step S130 may include the following steps:

[0108] S131: According to the current vibration frequency, the current amplitude of each test region, and the sensing coefficient, the sub - vibration amount of each test region can be determined.

[0109] S132: According to the current vibration data, the sensing coefficient, and the area and the elastic coefficient of each test region, determine the total vibration amount of the housing.

[0110] Among them, in step S131, the determination method of the sub - vibration amount E 1 of each test region can all refer to the following method:

[0111]

[0112] Among them, f represents the vibration frequency, A f represents the amplitude corresponding to the vibration frequency f, and g(f) represents the sensing coefficient corresponding to the vibration frequency f. f1 and f2 represent the minimum value and the maximum value of the vibration frequency range.

[0113] In an example, if the current vibration frequency is a fixed value, then f1 = f2 = f = the current vibration frequency (that is, no summation is required). Obtain the induction coefficient corresponding to the current vibration frequency, and the amplitude corresponding to the current vibration frequency of each test region, and substitute them into the above formula to obtain the sub - vibration amount of each test region.

[0114] In another example, if the current vibration frequency is within a frequency range, f1 represents the minimum value in the frequency range, and f2 represents the maximum value in the frequency range. f takes on each frequency value within the frequency range in turn, and the corresponding induction coefficient at each frequency value, as well as the amplitude of each test area corresponding to that frequency value, are obtained. The product of the three at that frequency value is calculated, and finally, the products corresponding to each frequency value within the frequency range are summed to obtain the sub-vibration amount corresponding to each test area.

[0115] In step S132, the total vibration amount of the housing can characterize the vibration amount actually perceived by the user. The total vibration amount E of the housing feel can be determined in the following manner:

[0116]

[0117] where f represents the vibration frequency, A f represents the amplitude corresponding to the vibration frequency f, and g(f) represents the perception coefficient corresponding to the vibration frequency f. f1 and f2 represent the range of the vibration frequency. S represents the area of each test area, k represents the elastic coefficient of the housing. M represents the number of test areas set as M.

[0118] In this step, during the process of determining the total vibration amount, the sub-vibration amounts of each test area are not simply summed. Instead, on the basis of considering the vibration frequency, the amplitude of each test area, and the perception coefficient of the human hand, the influence of the material of the housing is also considered, so that the vibration amount can be obtained more comprehensively and accurately.

[0119] It can be understood that before determining the formulas for the above sub-vibration amount and total vibration amount, the relationship between the influencing factors and the vibration amount can be obtained, such as: the total vibration amount is related to the sum of the sub-vibration amounts; due to the relationship between displacement and potential energy, the vibration amount is related to the square of the amplitude; there is a linear relationship between the vibration amount and the frequency.

[0120] For flexible materials and rigid materials, assuming that in the free vibration state with the same driving force, the total vibration energy E' of the flexible material and the rigid material is the same. At the maximum amplitude, the kinetic energy is 0 and the potential energy is the largest. Combining Figure 6 the amplitude of the flexible material and Figure 7 the amplitude of the rigid material shown (the solid line in the figure represents the state of the housing when not pressed, and the dotted line represents the state when pressed), the amplitude X of the flexible material 1 is greater than the amplitude X of the rigid material 2 . When the hand presses on the housing of the flexible material and the housing of the rigid material, due to the restriction of the hand, the amplitudes of the flexible material and the rigid material housing both become X 3 (X 3 is the gap between the hand and the vibration plane of the housing).

[0121] Combined with the foregoing embodiments, it is known that: k 1 <k 2 , then the remaining kinetic energy E 2 ’ of the rigid material and the remaining kinetic energy E 1 ’ of the flexible material satisfy:

[0122] Then the remaining kinetic energy E 2 ’ < E 1 ’.

[0123] The remaining kinetic energy is the main source of the vibration perceived by humans. The remaining kinetic energy and the elastic coefficient k are negatively correlated. Therefore, the vibration amount perceived by the human hand is also negatively correlated with the elastic coefficient. Therefore, the coefficient term of k in calculating the total vibration amount is

[0124] In an exemplary embodiment, step S112 may include the following steps:

[0125] S1121. According to the first operation instruction in the third display area of the application interface of the preset application, obtain the area of each test area represented by the first operation instruction, and the elastic coefficient of the housing.

[0126] The method of this embodiment further includes the following steps:

[0127] S140. Control the first display area of the application interface to display the sub-vibration amounts of each test area and the total vibration amount of the housing, and control the second display area of the application interface to display the perception coefficient.

[0128] In step S1121, the application interface of the preset application is as Figure 8 shown, including three display areas: a first display area 10, a second display area 20, and a third display area 30.

[0129] Among them, the third display area 30 is the main area for interacting with the user, used to receive the operation instruction of the user, and determine the parameters input by the user according to the operation instruction. For example, according to the first operation instruction of the user, obtain the area of each test area input by the user (the areas of each test area may be the same), the distribution of the test areas (the distribution quantity of the test areas in the horizontal and vertical directions), and the elastic coefficient of the housing. Combined Figure 8 it can be known that the input positions of the test area area and the elastic coefficient are at different positions in the third display area. In addition, according to the second operation instruction of the user, the storage location of the reference vibration data can be obtained, which can be seen in the following Figure 2 corresponding embodiment.

[0130] In step S140, in the first display area 10, the sub-vibration amounts corresponding to multiple test areas and the total vibration amount can be displayed. Combined Figure 5As shown, the test areas 40 are distributed at intervals in the horizontal and vertical directions during the setting process. Therefore, when displaying the sub-vibration amounts of each test area 40, the sub-vibration amounts of multiple test areas 40 can be displayed on the same coordinate axis, which is convenient for clearly observing the distribution of the sub-vibration amounts. The total vibration amount can be displayed below the coordinate axis. When the total vibration amount is too large, it can be adaptively adjusted in combination with the vibration conditions of different test areas 40.

[0131] In the second display area 20, the perception coefficient corresponding to the current vibration frequency can be displayed. The method for determining the induction coefficient can be referred to the following Figure 4 corresponding embodiments, which will not be elaborated here.

[0132] In other embodiments of the present disclosure, the application interface of the preset application can also display the vibration amount of another terminal device, which is convenient for comparing the vibration amounts of two terminal devices. For example, comparing the vibration amounts of different products, or comparing the vibration amount results before and after optimizing the product vibration amount.

[0133] In an exemplary embodiment, as Figure 2 shown, step S110 in this embodiment may include the following steps:

[0134] S1101. Obtain the current vibration frequency.

[0135] S1102. According to the second operation instruction, obtain the pre-stored reference vibration data.

[0136] S1103. According to the current vibration frequency, respectively determine the current amplitude corresponding to each test area in the reference vibration data at the current vibration frequency.

[0137] Among them, in step S1101, the current vibration frequency can be detected by an audio analyzer and sent to the preset application. Or, the preset application obtains the current vibration frequency according to the audio or sound source information played by the current speaker.

[0138] In step S1102, the reference vibration data includes: the mapping relationship between the vibration frequency and the amplitude of each test area in multiple test areas.

[0139] In this step, the second operation instruction can be, for example, a touch instruction or a voice instruction for obtaining the pre-stored reference vibration data.

[0140] In an example, step S1102 includes the following steps:

[0141] S1102-1. According to the second operation instruction in the third display area in the application interface of the preset application, obtain the storage address of the reference vibration data.

[0142] In this step, in combination with Figure 8As shown, on the application interface of the preset application, in addition to the first display area 10 for displaying the vibration amount, there is also a third display area 30 serving as a parameter input area. According to different operation instructions of the user in the third display area, the preset application can obtain input parameters corresponding to the operation instructions. For example, the parameters input by the user include: the storage location of the reference vibration data, the number and coordinates of the divided test areas, the area of the test area, and the elastic coefficient of the housing material of the terminal device, etc.

[0143] In this step, the input position of the second operation instruction can be, for example, the position of "mobile phone case vibration data" on the left side in the third display area. The second operation instruction is used to indicate the storage location of the reference vibration data. For example, when the preset application receives a touch instruction for the user to click and select the storage address in the parameter input area, it can obtain the specific storage address corresponding to the end position of the user's click.

[0144] S1102-2. Obtain the reference vibration data according to the storage address.

[0145] In this step, according to the storage address, the preset application can link to the storage address to obtain or call the reference vibration data.

[0146] In step S1103, according to the obtained reference vibration data and the current vibration data, the current amplitude corresponding to the current vibration data of each test area can be obtained by looking up the table in a traversal query manner in the reference vibration data.

[0147] In an exemplary embodiment, the method of this embodiment further includes: S200. Determine the reference vibration data. This step can be performed during the factory process of the terminal device, and the determined reference vibration data is stored in the terminal device for standby.

[0148] As Figure 3 shown, step S200 in this embodiment can include the following steps:

[0149] S201. Control the speaker to play a preset sound source, and the preset sound source corresponds to a preset frequency range.

[0150] S202. For each of the multiple test areas, obtain multiple amplitudes corresponding to multiple frequencies in the preset frequency range one by one.

[0151] S203. Store the mapping relationship between the frequencies and amplitudes of the obtained multiple test areas in a preset format.

[0152] Among them, in step S201, the preset frequency range is, for example, 150 hz to 1500 hz, and the preset sound source is, for example, a test sound source within this frequency range. During the test, the preset application can control the speaker of the terminal device to play the test sound source at the maximum volume.

[0153] It is understandable that the preset frequency range includes most of the frequencies that can cause the housing to vibrate and can be perceived by the user. For vibrations at 1500 hz and below, the user can clearly perceive them; for vibrations above 1500 hz, the user is less likely to perceive them. Due to the limitations of the sound emission of the terminal device's speaker, it is difficult to emit sounds below 150 hz, and the vibration of the housing can be ignored. Therefore, the preset frequency range is set at 150 hz to 1500 hz.

[0154] In step S202, for each test area, the preset frequency range is swept to obtain multiple amplitudes corresponding to multiple frequencies one by one.

[0155] In this step, the frequency step can be customized to set an equally spaced frequency sequence within the preset frequency range. For example, if the frequency step is 50 hz, the frequency sequence includes multiple frequencies such as 150 hz, 200 hz, 250 hz... 1450 hz, 1500 hz. At each frequency in the frequency sequence (the selected frequency can be within the error range of the corresponding frequency in the frequency sequence), the amplitude of each test area is measured respectively.

[0156] In this step, the amplitude can be measured in the following way: at a frequency, the amplitude of the center point of each test area is measured separately with a laser rangefinder as the amplitude of the test area. And so on, at each frequency, the amplitudes of each test area are obtained.

[0157] The amplitude data detected by the laser rangefinder can be converted into voltage values through an audio analyzer (APX500), and the voltage values are used to represent the test amplitude results. Among them, the audio analyzer (APX500) can convert the time-domain data (time - amplitude) measured by the laser rangefinder into frequency-domain data (frequency - amplitude). The conversion interface of the audio analyzer can be referred to Figure 9 As shown, the conversion relationship between the voltage value and the displacement amount of the amplitude is 5 mv = 1 um. Figure 9 What is shown is the time-domain data interface during the detection process. The horizontal axis is time, and the vertical axis is voltage (which can represent the corresponding amplitude).

[0158] In step S203, the preset format includes the stored file type and the storage order. For example, the stored file types are Excel, TXT, etc., and the storage order follows the numbering order of the test areas.

[0159] In one example, this step can store the relationship between the frequency and amplitude of each test area obtained in step S202. For example, store the Figure 10 frequency and amplitude curves of each test area as shown, with the horizontal axis being frequency and the vertical axis being amplitude. Figure 10The frequency and amplitude under each test area are non-linearly related. Alternatively, a corresponding table of frequency and amplitude for each test area is stored.

[0160] In another example, in combination with Figure 11 As shown, this step can store the relationships between frequency and amplitude under each test area in the same table.

[0161] In this example, the preset format can be stored as an Excel table. In the table, the order of data storage is consistent with the order in which the preset application reads the data. For example, as Figure 11 shown, in the order of data storage: the first column is a sequence of equally spaced frequencies within the preset frequency range (150 hz to 1500 hz), where the frequency step is 50 hz; starting from the second column to the last column in sequence are: starting from the first test area on the housing, along the width direction from left to right, then to the first test area in the next row, until after traversing all test areas from left to right and top to bottom, the amplitude corresponding to each test area at the corresponding frequency.

[0162] In an exemplary embodiment, as Figure 4 shown, step S120 in this embodiment may include the following steps:

[0163] S1201. Obtain a first function model and a second function model.

[0164] S1202. Determine a current perception threshold corresponding to the current vibration frequency according to the current vibration frequency and the first function model.

[0165] S1203. Determine a perception coefficient corresponding to the current vibration frequency according to the current perception threshold and the second function model.

[0166] Among them, in step S1201, the first function model is used to characterize the corresponding relationship between vibration frequency and perception threshold, and the second function model is used to characterize the corresponding relationship between perception coefficient and perception threshold.

[0167] The first function model and the second function model can be determined, for example, after obtaining reference vibration data and can be pre-stored in the terminal device. The preset application can call the first function model and the second function model.

[0168] In step S1202, according to the first function model, when any frequency is known, the perception threshold corresponding to that frequency can be known. Therefore, when the current vibration frequency is known, its corresponding current perception threshold is determined according to the first function model.

[0169] In step S1203, according to the second function model, when any perception threshold is known, the corresponding perception coefficient can be obtained. Therefore, in combination with the current perception threshold obtained in step S1202, the corresponding current perception coefficient can be determined according to the second function model, and the current perception coefficient corresponds to the current vibration frequency as well.

[0170] In an exemplary embodiment, the method of this embodiment further includes: S300, a method for determining the first function model and the second function model. This step can be performed after determining the reference vibration data in step S200, and the determined first function model and second function model are stored in the terminal device for standby.

[0171] In this embodiment, step S300 may include the following steps:

[0172] S301, determine the first function model.

[0173] In this step, the form of the first function model can be determined first as follows:

[0174] T f =l 1 f 6 +l 2 f 5 +l 3 f 4 +l 4 f 3 +l 5 f 2 +l 6 f 1 +l 7 f 0

[0175] Wherein, T f is the vibration perception threshold at frequency f, f is the frequency, and l 1 to l 7 are coefficients. The coefficients in the first function model can be determined by fitting through MATLAB (Matrix Laboratory). The fitting process can include the following steps, for example:

[0176] (1) Obtain multiple groups (such as 11 groups) of test data pairs, and each group of data includes the frequency and the amplitude that can be perceived by the user at the corresponding frequency. The more data pairs, the more accurate the fitted coefficients.

[0177] (2) Input the multiple groups of data into MATLAB, and set the form of the above sixth-order polynomial in MATLAB.

[0178] (3) According to the multiple groups of test data pairs, input them into the polynomial, and sequentially obtain the coefficients of each item of l 1 to l 7 ​

[0179] After obtaining the coefficients, when any frequency value f is known, the corresponding perception threshold T can be determined according to the first function model f , where f is within the preset frequency range of 150 hz to 1500 hz. The fitting curve of the first function model is as Figure 12 shown, where the abscissa is the vibration frequency and the ordinate is the human hand perception threshold (amplitude data). As the vibration frequency increases, the human hand perception threshold also increases.

[0180] S302. Determine the second function model.

[0181] In this step, the form of the second function model is determined according to the first function model as follows:

[0182]

[0183] where Tf represents the perception threshold corresponding to the frequency f, and Tfmin represents the minimum value of the perception threshold obtained in the first function model. The second function model can be determined using the perception threshold obtained by the first function model.
