With the continuous development of terminal technology, terminal devices generally have a function of playing music.
Currently, a terminal device may play music through an audio output module (e.g., a speaker) of the terminal device to display sound effects of the music to a user. Specifically, when the terminal device plays music through the speaker, the user can listen to the music played by the terminal device through his/her ear, thereby distinguishing the sound effects of the music (e.g., high pitch, middle pitch, low pitch, etc. in the music) to enjoy the music.
However, when the user is in a noisy environment, since the music played by the terminal device through the audio output module may not be clearly transmitted to the user's ear, the user may not clearly recognize the sound effect of the music. That is, in some scenarios, the terminal device may present music to the user with poor sound effect.

Namely, the processor or the terminal can realize the method for displaying the sound effect provided by the embodiment of the invention by running the software program in the android operating system.
The flexible device in embodiments of the present invention may be a device having a flexible screen. The device may be a terminal device, and the terminal device may be a mobile terminal or a non-mobile terminal. By way of example, the mobile terminal may be a mobile phone, a tablet computer, a child watch, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.
The execution main body of the method for displaying sound effect provided by the embodiment of the present invention may be the flexible device, or may also be a functional module and/or a functional entity capable of implementing the method for displaying sound effect in the flexible device, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a flexible device as an example to exemplarily describe the method for exhibiting sound effect provided by the embodiment of the present invention.
In the embodiment of the present invention, when a user uses a flexible device to play an audio signal (e.g., music, etc.), the flexible device may show a sound effect of the audio signal to the user by obtaining frequency values of the audio signal, determining K first frequency ranges to which the frequency values belong (the K first frequency ranges correspond to K deformation regions of the flexible device one to one), and controlling each of the K deformation regions of the flexible device to deform according to a corresponding deformation amount. So, in the scene that the user can't distinguish audio signal's audio effect through the sense of hearing, because flexible equipment can show audio signal's audio effect to the user through taking place deformation, consequently the user can experience flexible equipment's deformation through the sense organ to distinguish audio signal's audio effect, thereby can improve in this scene, flexible equipment shows audio signal's audio effect to the user. That is, in this scenario, the flexible device may be better used to present the acoustics effect of the audio signal by means other than outputting sound (e.g., deformation of the flexible device in the embodiment of the present invention).
The following describes an exemplary method for displaying sound effect according to an embodiment of the present invention with reference to the accompanying drawings.
As shown in fig. 2, an embodiment of the invention provides a method for exhibiting sound effect, which may include the following steps S201 to S203.
S201, the flexible device obtains M frequency values.
The M frequency values are frequency values obtained by sampling a target audio signal to be played by the flexible device, and M is a positive integer.
In the embodiment of the invention, in order to enable the flexible device to control the deformation region of the flexible device to generate corresponding deformation according to the frequency of the target audio signal in real time in the process of playing the target audio signal by the flexible device, so as to display the sound effect of the target audio signal to a user in real time, the embodiment of the invention can sample the target audio signal in real time. Moreover, when the playing time corresponding to the target audio signal is long, the embodiment of the invention can process the sampling points once after sampling the preset number of sampling points. Therefore, the processing performance of the flexible equipment can be balanced on the basis of ensuring that the flexible equipment deforms in a deformation area to show the sound effect to a user in real time.
In the embodiment of the present invention, the preset number may be 1024 or any other possible numerical value that meets the actual use requirement, and the embodiment of the present invention is not limited. That is, in the embodiment of the present invention, the flexible device may process each 1024 sampling points of the target audio signal after sampling the 1024 sampling points. Specifically, the method for processing the sampling point by the flexible device will be described in detail in S202 below, and will not be described herein again.
Optionally, in the embodiment of the present invention, the target audio signal may be any possible audio signal such as music, a recording, a voice, and the like, and may be determined specifically according to an actual use requirement, which is not limited in the embodiment of the present invention. In this embodiment of the present invention, the target audio signal may specifically be an audio clip in an audio signal to be played by the flexible device, that is, the flexible device may execute the method provided in the embodiment of the present invention by using each audio clip in the audio signal to be played by the flexible device as a unit. Therefore, the sound effect of the audio signal can be displayed to a user in real time in the process of playing the audio signal by the flexible equipment.
It should be noted that, in the embodiment of the present invention, an example of sampling and processing an audio segment by a flexible device is described. In a specific implementation, for each audio clip in the audio signal to be played by the flexible device, the flexible device needs to execute the method provided by the embodiment of the present invention, that is, in a process of playing the audio signal by the flexible device, the flexible device can circularly execute the method provided by the embodiment of the present invention, so as to display the sound effect of the audio signal to the user in real time.
In this embodiment of the present invention, in a process of playing an audio signal by a flexible device, taking an audio clip (for example, the above-mentioned target audio signal) in the audio signal as an example, the flexible device may perform frequency detection on the target audio signal through a sound detection unit in the flexible device, so as to sample the target audio signal. Specifically, in a case where the target audio signal is an analog audio signal, the flexible device may convert the analog audio signal into a digital audio signal, perform fourier transform on the digital audio signal to obtain a frequency spectrum of the digital audio signal, and then sample the frequency spectrum to obtain a result of sampling the target audio signal, for example, the flexible device may sample the frequency spectrum to obtain the M frequency values.
Of course, it can be understood that, in the embodiment of the present invention, in the case that the target audio signal is a digital audio signal, the flexible device may directly perform fourier transform on the digital audio signal to obtain a frequency spectrum of the digital audio signal, and then sample the frequency spectrum to obtain a result of sampling the target audio signal, for example, the flexible device may sample the frequency spectrum to obtain the M frequency values.
Optionally, in the embodiment of the present invention, with reference to fig. 2, as shown in fig. 3, the above S201 may be specifically implemented by the following S201a and S201 b.
S201a, the flexible device samples the target audio signal to obtain T frequency values.
In the embodiment of the present invention, the target audio signal may include various frequency values, for example, frequency values within a range of human auditory frequencies may be included, and frequency values outside the range of human auditory frequencies may be included. That is, the result of the flexible device sampling the target audio signal may include frequency values within the range of human auditory frequencies, and may also include frequency values outside the range of human auditory frequencies. In order to remove frequency values outside the range of human auditory frequencies, the flexible device may obtain frequency values within the range of human auditory frequencies, i.e., the above-mentioned M frequency values, from the T frequency values after sampling the target audio signal to obtain T frequency values.
S201b, the flexible device obtains M frequency values belonging to a preset second frequency range from the T frequency values.
Wherein T is a positive integer greater than or equal to M, and the second frequency range may be used to indicate a human auditory frequency range, i.e., the second frequency range may be 20Hz (hertz) -20KHz (kilohertz).
Optionally, in an embodiment of the present invention, the second frequency range may specifically be 100Hz to 20 KHz. In this way, the ultra-low sound (e.g., frequency value in the range of 20Hz-99 Hz) which is inconvenient for human ears to hear can be removed, so that the sound effect of the audio signal presented to the user by the flexible device can be improved.
In the embodiment of the invention, when the flexible equipment shows the sound effect of the target audio signal to the user, the flexible equipment can remove the frequency value outside the range of the auditory frequency of the human ear, so that the flexible equipment only processes the frequency value within the range of the auditory frequency of the human ear without processing the frequency value outside the range of the auditory frequency of the human ear, and further the invalid processing of the frequency value outside the range of the auditory frequency of the human ear by the flexible equipment can be avoided.
S202, the flexible device determines K first frequency ranges to which the M frequency values belong from the preset N first frequency ranges.
Each of the K first frequency ranges corresponds to at least one of the M frequency values, the N first frequency ranges correspond to the N deformation regions one to one, each of the N deformation regions corresponds to one deformation amount, and K is an integer less than or equal to N.
In the embodiment of the present invention, after the flexible device obtains M frequency values of the target audio signal, the flexible device may determine a first frequency range to which the M frequency values belong in N preset first frequency ranges, that is, the K first frequency ranges. Then, the flexible device can determine K deformation regions of the flexible device corresponding to the K first frequency ranges, so that the flexible device can control the K deformation regions to deform according to the corresponding deformation amounts, and the sound effect of the target audio signal is displayed to the user. In this way, the flexible device can present the sound effect of the audio signal played by the flexible device to the user.
Optionally, in this embodiment of the present invention, the N first frequency ranges may be frequency ranges obtained by dividing a human ear hearing frequency range, where N may be a preset numerical value, and may be used to represent the number of the divided frequency ranges.
It can be understood that the value of N may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
For example, assuming that the human auditory frequency range is 20Hz-20KHz and N is 20, the 20 first frequency ranges may be frequency ranges divided by 20Hz-20 KHz. Specifically, the average division of 20Hz-20KHz into 20 parts can be used to divide 20Hz-20 KHz. Specifically, the frequency range after dividing 20Hz to 20KHz may be: 20Hz-1KHz, 1KHz-2KHz, 2KHz-3KHz, … 19KHz-20 KHz.
Optionally, in this embodiment of the present invention, the flexible device may include N deformation regions. Specifically, when the flexible device is a device having a flexible screen, the N deformation regions may be N regions on the flexible screen. That is, it can be understood that the N deformation regions constitute the flexible screen.
In the embodiment of the present invention, N deformation regions of the flexible device correspond to the N first frequency ranges one by one, that is, one deformation region corresponds to one first frequency range.
It is understood that, in the embodiment of the present invention, a possible manner may be that the number of the deformation regions of the flexible device is determined, and then the number of the first frequency ranges is determined according to the number of the deformation regions of the flexible device. Another possible way is: the number of the first frequency ranges may be determined, and then the number of the deformation regions of the flexible device may be determined according to the number of the first frequency ranges. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
For example, assuming that the flexible device is a device having a flexible screen, and a length of a certain side of the flexible screen (for example, a longer side of the flexible screen) is 15cm (centimeter), and assuming that the number of the first frequency ranges is determined first, then the number of deformation regions of the flexible device is determined according to the number of the first frequency ranges, and assuming that the number N of the first frequency ranges is 20, after determining that the number N of the first frequency ranges is 20, the side of the flexible screen may be divided into 20 regions (as shown in (a) of fig. 4), that is, a region block with a side length of 0.75cm (centimeter) is one deformation region (as shown in (b) of fig. 4).
Optionally, in the embodiment of the present invention, as shown in fig. 5 in combination with fig. 2, the above S202 may be specifically implemented by the following S202 a.
S202a, the flexible device determines, for each of the M frequency values, a frequency range to which one frequency value belongs from the preset N first frequency ranges, so as to determine K first frequency ranges from the N first frequency ranges.
In this embodiment of the present invention, after the flexible device obtains M frequency values, the flexible device may determine, according to each of the M frequency values, a frequency range to which the frequency value belongs from N preset first frequency ranges, so as to determine, from the N preset first frequency ranges, K first frequency ranges to which the M frequency values belong.
It is understood that, in the embodiment of the present invention, the K first frequency ranges may be all of the N first frequency ranges (i.e., K ═ N), or may be some of the N first frequency ranges (i.e., K < N). And, each of the K first frequency ranges corresponds to at least one of the M frequency values.
Exemplarily, assuming that M is 5, that is, the flexible device obtains 5 frequency values, and the 5 frequency values are 500Hz, 900Hz, 2.5KHz, 6KHz and 8KHz, and assuming that N is 20, and the preset 20 first frequency ranges are 20Hz-1KHz, 1KHz-2KHz, 2KHz-3KHz and … 19KHz-20KHz, respectively, then the flexible device may determine that 500Hz and 900H belong to the range of 20Hz-1KHz, 2.5KHz belongs to the range of 2KHz-3KHz, 6KHz belongs to the range of 6KHz-7KHz and 8KHz belongs to the range of 8KHz-9KHz, that is, the flexible device may determine, according to each frequency value of the 5 frequency values, a frequency range to which each frequency value of the 5 frequency values belongs from the preset 20 first frequency ranges, that is, the above-mentioned 20Hz-1KHz, 2-3 KHz, 2KHz, The 4 first frequency ranges of 6KHz-7KHz and 8KHz-9KHz, so that the flexible device can determine that the 5 frequency values belong to the 4 first frequency ranges (i.e., K ═ 4 as described above).
In the embodiment of the invention, when the flexible device displays the sound effect of the target audio signal to the user, the flexible device can determine K first frequency ranges to which the frequency values belong in the N first frequency ranges according to the obtained frequency values of the target audio signal, so that the flexible device can determine K corresponding deformation regions in the N deformation regions of the flexible device according to the K first frequency ranges.
S203, in the process that the flexible device plays the target audio signal, the flexible device controls each deformation area in the K deformation areas of the flexible device to deform according to the corresponding deformation amount.
And the K deformation areas are deformation areas corresponding to the K first frequency ranges in the N deformation areas.
Optionally, in an embodiment of the present invention, each of the N first frequency ranges corresponds to a preset frequency value, and the preset frequency value corresponding to one first frequency range may be used to indicate a deformation amount of the deformation region corresponding to one first frequency range.
Optionally, in the embodiment of the present invention, the preset frequency value corresponding to a first frequency range may be any positive integer of 100 and 1000.
Optionally, in this embodiment of the present invention, the N preset frequency values corresponding to the N first frequency ranges may be preset in the flexible device by a manufacturer of the flexible device; a setup interface may also be provided by the manufacturer of the flexible device and set up by the user through the setup interface.
Optionally, in the embodiment of the present invention, after the flexible device determines the K first frequency ranges to which the M frequency values belong, the flexible device may calculate deformation amounts of the K deformation regions corresponding to the K first frequency ranges according to preset frequency values corresponding to the K first frequency ranges, so as to control the K deformation regions to deform according to the corresponding deformation amounts.
In the embodiment of the invention, the flexible equipment is independently controlled when controlling the deformation of the K deformation areas, namely the flexible equipment respectively controls each deformation area in the K deformation areas to deform according to the deformation amount corresponding to the deformation area. Therefore, the flexible device can deform by controlling the K deformation areas so as to show the sound effect of the target audio signal to a user. In the process that the flexible equipment controls the deformation area to deform, a user can feel the deformation of the flexible equipment through sense organ so as to clearly distinguish the sound effect of the audio signal. Therefore, in a scene that the user cannot distinguish the sound effect of the audio signal through hearing (for example, the user is in a noisy environment), the sound effect of the audio signal displayed to the user by the flexible device can be improved.
Optionally, in this embodiment of the present invention, the flexible device may calculate the deformation amounts of the K deformation regions corresponding to the K first frequency ranges through the following formula. Wherein the formula may be: and the deformation quantity is the preset frequency value and the deformation coefficient.
Optionally, in the embodiment of the present invention, the deformation coefficient may be preset in the flexible device by a manufacturer of the flexible device, and the deformation coefficient may be 0.01.
It is understood that, in the embodiment of the present invention, the deformation coefficient may be a bending coefficient, which is used to indicate a degree of change of bending when the flexible device is deformed.
For example, taking one of the K first frequency ranges as an example, assuming that the preset frequency value corresponding to the first frequency range is 500, the deformation amount of the deformation region corresponding to the first frequency range may be 500 × 0.01 — 5. Specifically, when the deformation region is deformed, the deformation amount of the deformation region may be 5.
Optionally, in this embodiment of the present invention, the deformation amount of each deformation region in the flexible device is positively correlated with the corresponding value of the first frequency range. I.e. can be understood as: the larger the value of a first frequency range, the larger the amount of deformation of the deformation region corresponding to the first frequency range.
Illustratively, taking deformation region N1 and deformation region N2 in the flexible device as an example, assume that the first frequency range corresponding to deformation region N1 is P1, the first frequency range corresponding to deformation region N2 is P2, and the values in P1 are all greater than those in P2, so that if P1> P2, the deformation amount of deformation region N1 corresponding to P1 is greater than that of deformation region N2 corresponding to P2. Wherein, the above-mentioned values of P1 being greater than those of P2 means that any one of P1 is greater than any one of P2.
In the embodiment of the present invention, the flexible device may determine, according to the obtained frequency value of the target audio signal to be played, a deformation region corresponding to the first frequency range to which the frequency value belongs, so that each deformation region in the deformation region of the flexible device may deform according to the corresponding deformation amount. As such, when the user is in a noisy environment, even if the user cannot distinguish the sound effect of the audio signal (e.g., treble, midrange, bass, etc. in the audio signal) by hearing, the user can sense the deformation of the flexible apparatus by sense to clearly distinguish the sound effect of the audio signal. Therefore, in a scene that the user cannot distinguish the sound effect of the audio signal through hearing (for example, the user is in a noisy environment), the sound effect of the audio signal displayed to the user by the flexible device can be improved.
When the user can not distinguish the sound effect of the music (such as high pitch, middle pitch, low pitch and the like in the music) through the loudspeaker, the user can clearly distinguish the sound effect of the music by feeling the deformation of the deformation area of the flexible equipment.

In specific implementation, the method for displaying sound effect shown in each of the above drawings may also be implemented by combining any other drawings that may be combined, which are illustrated in the above embodiments, and will not be described herein again.
