Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.
In order to solve the above technical problem, an embodiment of the present disclosure provides a method for controlling a display state of a housing, which may be applied to an electronic device, where a state-adjustable device is disposed in a housing of the electronic device, and a display state of the housing may be adjusted by adjusting a display state of the state-adjustable device. The electronic equipment can control the display state of the state-adjustable device to synchronously change along with the audio information, so that the effect of changing the display state of the shell and the audio information is achieved, and the use experience is improved.
It should be noted that the state change of the state-adjustable device may include at least one of the following: the display area is changed by changing different color states, transparency, saturation and area of the display area.
Taking the example of the variation between different color states, the state-tunable-device may be an electrovariable film, which may be disposed at the outermost layer or at an intermediate layer or at the innermost layer of the housing of the electronic device. When disposed in the interlayer or innermost layer of the electronic device, a transparent layer or other single color layer may be disposed outside the electrochromic film so that light thereof may be radiated to the outside to form different colors. The electrovariable film can display different colors such as red, green and the like when the input voltage is different, and can be selected according to specific scenes.
Taking the example of the change between different transparencies or the change between different saturations of the same color, the state-tunable-device may be a Polymer Dispersed Liquid Crystal (PDLC), and the PDLC layer may be disposed at the outermost layer or at an intermediate layer or at the innermost layer of the housing of the electronic device. When disposed in the interlayer or innermost layer of the electronic device, the PDLC layer may be provided with a transparent layer in addition to the PDLC layer so that light thereof may be radiated to the outside, resulting in different transparency. The PDLC layer can adjust the optical axis orientation of the liquid crystal when the input voltage is different, the refractive index of the optical axis of the small droplet formed by the liquid crystal molecules is matched with that of the matrix, the display state of the state adjustable device is a transparent state, and after the input voltage is cancelled, the liquid crystal restores the original light scattering state, so that the opaque or semitransparent milky white state is displayed. Of course, the default state of the PDLC layer may also be set to a transparent state, which works in the same way as the opaque state, and will not be described in detail here.
Considering the working principle of the PDLC layer and the audio characteristics of the audio file, the period of the driving waveform is less than or equal to the minimum time length between two adjacent trigger nodes of the audio file, so that the driving waveform can be changed at least once in one beat. Taking the example that the trigger node is a beat, the period of the driving waveform is less than or equal to the period of one beat of the audio file, thereby ensuring that the period can be changed at least once within one beat.
Referring to fig. 1, a method for controlling a display state of a housing includes steps 11 to 12:
in step 11, the audio file is mapped to a driving waveform according to the audio playing effect.
In this embodiment, the processor in the electronic device may detect whether a service request for playing an audio file is indicated, where the service request includes, but is not limited to, playing an audio and video, reminding an incoming call, reminding a short message, and the like, and the service request requires the electronic device to play a section of audio file to achieve an effect of reminding a user.
In this embodiment, when the processor detects a service request including an audio playing scene, an audio file corresponding to the service request may be acquired.
In an example, the electronic device may pre-store audio files corresponding to various service types, such as an audio file a corresponding to an incoming call reminder, an audio file B corresponding to a short message reminder, and the like. That is to say, an audio file is preset in the electronic device, and when the processor obtains the service request, the processor can obtain the service type of the service request, and then the local memory queries the audio file corresponding to the service type and reads the audio file. In another example, an audio capture device, such as a microphone, is provided in the electronic device. When the processor acquires the service request, the audio acquisition device can be started. The audio acquisition device can acquire the information of the environment where the electronic equipment is located to obtain the audio file. In this way, the processor may retrieve the audio file captured by the audio capture device.
In this embodiment, after obtaining the audio file, the processor may obtain an audio playing effect of the audio file. The audio playing effect may include, but is not limited to, classical music, pop music, jazz, rock, normal, etc., and may be set according to a specific scene. The processor may map to the drive waveform according to the audio playback effect described above. In this example, the driving waveform is a waveform for representing a voltage value applied to the state-tunable device, and may include, but is not limited to: sine wave, square wave, sawtooth and PWM waveforms. In view of the performance of the state-tunable-device, the driving waveform in this example is a waveform that is more beneficial to the lifetime of the state-tunable-device, such as a driving waveform that is at least one of: sine wave, square wave or PWM waveform, thereby prolonging the service life of the state-adjustable device. It will be appreciated that the above examples are for illustration only and may in practice be determined from the lifetime practice of the state-tunable device.
In an example, the processor may map the driving waveforms by audio feature information, see fig. 2, including: in step 21, the processor may obtain audio characteristic information of the audio file, which may include, but is not limited to, tempo, pitch, audio segment energy, audio envelope level, subwoofer, and the like. Then, in step 22, the processor may obtain a driving waveform corresponding to the audio feature information based on the preset correspondence relationship between the audio feature information and the driving waveform. In the preset corresponding relationship between the audio characteristic information and the driving waveform, the audio characteristic information and the amplitude value of the driving waveform are in a linear relationship, or the amplitude values of the driving waveform are the same. The audio characteristic information and the amplitude value of the driving waveform are in a linear relation, and the linear relation can comprise positive correlation or negative correlation; taking the positive correlation as an example, when the audio characteristic information is the audio envelope level, if the audio envelope level is larger, the amplitude value of the corresponding driving waveform is larger, the driving waveform can be selected from the preset driving waveforms according to the audio included level, and each driving waveform driving state adjustable device has different display effects. Taking the same amplitude value of the driving waveforms in the corresponding relationship as an example, all the driving waveforms have the same amplitude value, so that each driving waveform driving state adjustable device has the same display effect.
In another embodiment, the electronic device may further store a preset correspondence between the audio characteristic signal and the transparency. In this way, after the electronic device acquires the audio feature signal, the target transparency corresponding to the audio feature signal can be acquired based on the correspondence. Then, based on a preset correspondence between the transparency and the driving waveform, the electronic device may obtain the driving waveform corresponding to the target transparency according to the transparency. In this embodiment, the driving waveform is obtained according to the transparency of the state-adjustable device, so that the state-adjustable device can be accurately controlled, and the control effect is improved.
In yet another example, the processor maps the driving waveforms by audio feature information, see fig. 3, including: in step 31, the processor may obtain audio characteristic information of the audio file, which may include, but is not limited to, tempo, pitch, audio segment energy, audio envelope level, subwoofer, and the like. In step 32, the processor may obtain an amplitude value of the driving waveform corresponding to the audio characteristic information based on a preset correspondence relationship between the audio characteristic information and the amplitude value. In the preset corresponding relationship between the audio characteristic information and the amplitude value, the audio characteristic information and the amplitude value may be in a linear relationship, or the amplitude values of the driving waveforms are the same. For example, the preset correspondence between the audio characteristic signal and the amplitude value may be a correspondence between audio segment energy and a driving waveform, and after the electronic device acquires the audio segment energy, a target amplitude value corresponding to the audio segment energy, for example, 10Vpp, may be found in the correspondence, where Vpp refers to a peak value of a sine wave; and then, adjusting the amplitude of a preset driving waveform (1Vpp) to 10Vpp so as to obtain a target driving waveform, and driving the state-adjustable device by using the 10Vpp driving waveform.
In an alternative example, step 33 is performed if the target amplitude value is greater than a preset threshold, otherwise it is not performed. In the example, larger audio characteristic information can be selected by screening the audio amplitude value, and the change of the audio can be fully sensed when the audio is played, so that the following effect of the display state and the audio playing can be better observed.
In step 33, the electronic device stores a preset driving waveform, and the processor may adjust the amplitude value of the driving waveform according to the amplitude value to obtain a target driving waveform; or setting a waveform generator, and taking the amplitude value as the gain (i.e. amplification factor) of the waveform generator, so that the waveform generator outputs a driving waveform corresponding to the amplitude value, and each driving waveform driving state adjustable device has different display effects. In addition, in this example, only one preset driving waveform needs to be stored, so that the occupied storage resource is reduced. Moreover, the amplitude value can be understood as the amplification factor of the control amplitude value, and can be used as the amplification gain of the amplification device, that is, the amplification factor of the amplification device is adjusted without adjusting the input drive waveform.
In yet another example, the processor maps the drive waveform by a characteristic value of each audio segment of the audio file, see fig. 4, including: in step 41, the processor may divide the audio file to obtain a plurality of audio segments; the length of the audio piece can be set, such as 5-20 ms. Taking an audio file stored locally as an example, the electronic device may obtain one or more audio clips of the audio file to be played. For example, the electronic device may adopt a preset window, for example, the window length is 20ms, and perform sliding processing according to a step length of 5ms each time to obtain each audio clip of the audio file; or, the audio file is equally divided to obtain one or more audio segments.
In step 41, the processor may obtain a feature value of each audio segment, where the feature value may include, but is not limited to, a value of one of features such as tempo, pitch, audio segment energy, audio envelope level, subwoofer, and the like. The feature value of each audio piece may be an average, a maximum, or a minimum of the feature values at different times of the audio piece. Taking the feature value as the audio segment energy as an example, the electronic device may obtain an energy spectrum of the audio segment, calculate the audio segment energy of the audio segment according to the energy spectrum, and use the audio segment energy as the feature value of the audio segment.
It should be noted that, in practical applications, the electronic device may also obtain a feature value in the audio file in advance, where the feature value reflects an audio playing effect, and store the feature value in the local storage. In this way, the processor can directly acquire the feature values of the audio segments in the audio file.
In step 42, the processor may obtain a feature value threshold corresponding to the feature of the audio segment, and compare the obtained feature value with the feature value threshold, so as to obtain a plurality of adjacent audio segments of which the feature values exceed the feature value threshold, and a segment combination composed of the plurality of adjacent audio segments. In step 43, the processor may obtain a driving waveform corresponding to each audio segment in the segment combination.
In this example, the driving waveforms corresponding to the segment combinations may have the following characteristics: the driving waveform corresponding to each audio segment in the segment combination is the same, or the amplitude of the driving waveform corresponding to each audio segment in the segment combination is linearly related to the audio characteristic information of the audio segment, or the driving waveform corresponding to each audio segment in the segment combination is related to the audio characteristic information with the maximum variation in the audio segment.
Taking the example that the driving waveforms corresponding to each audio segment in the segment combination are the same, the processor may output the same driving waveforms for each audio segment according to the range corresponding to the segment combination, so that the state-adjustable devices may change to the same state, for example, from transparent to opaque, from opaque to transparent, from the current color to another color, and from the current color to transparent.
Taking the example that the amplitude of the driving waveform corresponding to each audio segment in the segment combination is linearly related to the audio characteristic information of the audio segment, the processor may output a driving waveform whose amplitude is linearly related to the audio characteristic information, so that the state change of the state-adjustable device is kept synchronous with the change of the audio file.
Taking as an example that the driving waveform corresponding to each audio segment in the segment combination is related to the audio characteristic information with the largest variation in the audio segment, the processor may output a driving waveform with a magnitude related to the audio characteristic information with the largest variation, for example, if the envelope level of the first audio segment varies greatly, a driving waveform related to the envelope level is determined, and if the pitch variation of the second audio segment varies greatly, a driving waveform related to the pitch is determined, and the display state of the state-adjustable device is driven by the driving waveform, so that the variation of the display state is richer.
In an embodiment, considering that an audio file corresponding to a service request may be relatively large, if the audio file is played again after processing a complete audio file, a delay between playing and displaying states may be too large, and therefore, in this embodiment, the processor maps the audio file into a driving waveform according to an audio playing effect, as shown in fig. 5, including: in step 51, the processor may divide the audio file into a plurality of audio segments. In step 52, the processor may obtain each audio segment and a driving waveform corresponding to each audio segment; when a preset number (for example, 2 to 5, which may be set according to the length of the audio clip) of audio clips and driving waveforms corresponding to the preset number of audio clips are obtained, step 12 is executed again.
In another embodiment, considering that the audio file corresponding to the service request may be relatively large, if the audio file is played again after processing the entire audio file, the delay between the playing state and the displaying state may be too large, and therefore, in this embodiment, the processor maps the audio file to the driving waveform according to the audio playing effect, as shown in fig. 6, including: in step 61, the processor may obtain an audio segment of a preset length (e.g., 5-10 ms) of the audio file each time. In step 62, a driving waveform corresponding to the preset length of the audio segment is obtained. Step 12 is then performed. In this way, in this embodiment, the time for preprocessing can be reduced by acquiring the audio file as the audio clip, so as to shorten the time between the acquisition of the service request and the playing of the audio, thereby making the user unaware of the process of audio preprocessing. Or, the user can play audio and control the display state of the shell after selecting corresponding services.
In step 12, the state-adjustable device is driven based on the driving waveform so that the display state of the state-adjustable device follows the audio change.
In this embodiment, after the processor in the electronic device acquires the driving waveform, the state-adjustable device may be driven by using the driving waveform. Taking the example where the state-tunable-device is a PDLC layer, the default state of the PDLC layer may be a transparent state or an opaque state, and taking the example of the opaque state, the processor may send a driving waveform to the driving circuit, and the driving circuit applies a corresponding voltage to the input terminal of the state-tunable-device according to the driving waveform. Alternatively, the processor may send an instruction corresponding to the driving waveform to the driving circuit, and the driving circuit generates the corresponding driving waveform and outputs the driving waveform to the state-tunable device, or the driving circuit sequentially outputs electric signals according to the driving waveform and applies the electric signals to the input end of the state-tunable device.
It can be understood that after the voltage is input to the input end of the state-adjustable device, the state can be switched from the opaque state to the transparent state according to the voltage, and when the voltage of the input end disappears, the state is switched from the transparent state to the opaque state, so that the display state of the state-adjustable device is adjusted. The driving waveform is obtained in real time according to the audio signal and is applied to the input end of the state adjustable device in real time, so that the display state of the state adjustable device can be ensured to change along with the audio characteristic signal of the audio signal.
In the above embodiment, it is considered that the electronic device starts playing the audio file after acquiring the audio file, and the processor may drive the display state of the state-adjustable device after acquiring the driving waveform. In case the computing resources of the electronic device are sufficient, the audio file playing is substantially in synchronization with the change of the display state of the state-tunable device, i.e. the delay between visual and audible recognition by the user is not recognizable.
In practical applications, the electronic device may have situations such as insufficient computing resources, which may cause a delay between visual perception and auditory perception of a user, that is, considering that a certain duration (for example, 20ms) is required for a processor to acquire a driving waveform according to an audio file, a certain delay exists between a change of a display state and playing of an audio, and therefore, in an embodiment, driving the state-adjustable device based on the driving waveform to make the display state of the state-adjustable device follow the change of the audio includes: the processor may also not play the audio file first after obtaining the audio file, but obtain the driving waveform of the audio file first, and the manner of obtaining the driving waveform may refer to step 11, which is not described herein again. Then, after the processor obtains the driving waveform corresponding to the audio file, or the driving waveform corresponding to each audio segment of the audio file, or the driving waveform corresponding to a part of the audio file (an audio segment with preset duration or a preset number of audio segments), the processor may start playing the audio file, and drive the display state of the state-adjustable device based on the driving waveform corresponding to the audio file to follow the playing of the audio file. Thus, in the embodiment, by simultaneously triggering the audio trigger and the display state change, the delay between the audio trigger and the display state change can be reduced, and a better audio-visual effect can be achieved.
In an embodiment, the processor can perform follow-up control in the process of playing an audio file besides triggering the audio playing and driving the state-adjustable device at the same time, so as to achieve a better follow-up effect. Referring to fig. 7, in step 71, the processor may obtain a trigger node of the audio file, which may include, but is not limited to, a beat, a rhythm, or a play effect change point in audio, etc. In step 72, when playing the audio file, the state-adjustable device is driven at the trigger node of the audio file according to the driving waveform of each trigger node, so that the display state of the state-adjustable device changes synchronously with the audio file, and the trigger timing sequence is as shown in fig. 8. Referring to fig. 8, during the playing of an audio file, at each beat T, a voltage corresponding to a driving waveform is applied to the PDLC layer, thereby switching the PDLC layer from the opaque state to the transparent state.
Taking the example where the trigger node is a beat, the processor may perform a frequency domain transform, such as a fourier transform or a fast fourier transform, on the audio file to obtain frequency domain data. The processor may then perform a difference process on the frequency domain data to obtain difference data. Then, the processor may take the node corresponding to the differential signal exceeding the preset threshold in the differential data as a beat.
In practical application, the processor may further obtain an audio change difference in the audio file, for example, a difference between envelope voltages of two adjacent sampling points, or a difference between audio energies of two adjacent sampling points; and acquiring an audio frequency point of which the audio frequency change difference value is greater than a first preset threshold value in the audio file, and taking the audio frequency point as a trigger node. Therefore, the trigger node with the largest audio change difference can be selected in the example, the change of the audio can be fully sensed when the audio is played, and the following effect of the display state and the audio playing can be better observed. Or the processor may acquire an audio point in the audio file, where the audio change difference is smaller than a second preset threshold, and delete the audio point from the trigger node. Therefore, in this example, the trigger node with a small audio variation difference can be removed, the consumption of computing resources consumed by obtaining the driving waveform and the consumption of subsequent driving state adjustable devices can be reduced, and the following effect of the display state and the audio playing can be improved.
In one embodiment, the processor may drive the state-tunable-device based on the driving waveform, and pre-process the driving waveform before driving, see fig. 9, and in step 91, may filter the driving waveform; in step 92, the filtered drive waveform is amplified; in step 93, the state-tunable-device is driven with the amplified driving waveform. In this embodiment, the voltage of the driving waveform can meet the requirement of the state-adjustable device through filtering and amplification, and the stable operation of the state-adjustable device is ensured.
In an embodiment, it is considered that audio files corresponding to some service scenarios are small, and the playing time is short, for example, the incoming call audio reminding is usually 5-10 seconds, and if a user is busy, the user cannot timely hear the incoming call. In this scenario, referring to fig. 10, in step 101, the processor may acquire a service scenario after the audio file playing is finished. In step 102, the processor may obtain a driving waveform template corresponding to the service scene, where the driving waveform template may be set according to the service scene, for example, a driving waveform template corresponding to a flicker effect in an incoming call missed scene, a driving waveform template corresponding to a respiratory effect in an unread information scene, and the like. In step 103, the processor may control the state-tunable-device to follow the waveform changes in the drive waveform template according to the drive waveform template. Therefore, in the embodiment, the purpose of reminding the user is achieved by setting different display effects for different service scenes.
Therefore, the embodiment of the present disclosure may map the audio file into the driving waveform according to the audio playing effect; then, the state-adjustable device is driven based on the driving waveform to cause the display state of the state-adjustable device to follow the audio change.
