Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structure of a terminal device according to an embodiment of the present invention. Referring to fig. 1, the terminal device has a folding screen (including a first partial screen M and a second partial screen N), a folding axis P, a first speaker a, and a second speaker B.
The first partial screen M and the second partial screen M may be rotated along the folding axis P to have a certain folding angle θ therebetween. Optionally, the first partial screen M may be an upper half screen of the terminal device, and the second partial screen M is a lower half screen of the terminal device. Alternatively, the first partial screen M may be a left half screen of the terminal device, and the second partial screen N may be a right half screen of the terminal device.
The first speaker a and the second speaker B are disposed on both sides of the folding axis. Alternatively, when the first partial screen M may be an upper half screen of the terminal device and the second partial screen M is a lower half screen of the terminal device, the first speaker a may be disposed at the top of the terminal device, and the second speaker B may be disposed at the bottom of the terminal device. When the first partial screen M may be a left half screen of the terminal device and the second partial screen N may be a right half screen of the terminal device, the first speaker a may be disposed on the left side of the terminal device and the second speaker B may be disposed on the right side of the terminal device. Optionally, the first speaker a and the second speaker B are arranged opposite to each other.
It should be noted that fig. 1 is a schematic structural diagram of the terminal device in an exemplary form, and is not a limitation on the structure of the terminal device, and in an actual application process, the structure of the terminal device may be set according to an actual need, which is not specifically limited in the embodiment of the present invention.
In this application, the terminal device may obtain a folding angle between the first partial screen and the second partial screen, and set the audio playback mode of the first speaker and the second speaker to the stereo mode or the non-stereo mode according to the folding angle. When the folding angle is large, and the distance between the first loudspeaker and the second loudspeaker meets the stereo playing distance, the audio playing mode of the first loudspeaker and the second loudspeaker can be set to be a stereo mode, so that the audio which can be played by the first loudspeaker and the second loudspeaker can reach the stereo effect. When the folding angle is small, so that the distance between the first loudspeaker and the second loudspeaker does not satisfy the stereo playing distance, the audio playing mode of the first loudspeaker and the second loudspeaker can be set to be a non-stereo mode, and in the non-stereo mode, the waveforms of the audio played by the first loudspeaker and the second loudspeaker are the same, so that the interference between the audio played by the first loudspeaker and the second loudspeaker is reduced, and the audio playing effect is improved.
The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may be combined with each other, and the description of the same or similar contents in different embodiments is not repeated.
Fig. 2 is a first flowchart illustrating an audio control method according to an embodiment of the present invention. Referring to fig. 2, the method may include:
s201, acquiring a folding angle between a first part of screen and a second part of screen in the folding screen.
The execution main body of the embodiment of the invention can be terminal equipment, and can also be an audio control device arranged in the terminal equipment. Alternatively, the audio control means may be implemented by software, or the audio control may be implemented by a combination of software and hardware.
Optionally, a magnetic angle sensor may be disposed in the terminal device, and the folding angle between the first partial screen and the second partial screen may be acquired by the magnetic angle sensor.
For example, referring to fig. 1, a magnetic angle sensor may be disposed at a folding axis of the terminal device, so that the magnetic angle sensor collects the angle β, and the terminal device may calculate a folding angle θ between the first partial screen and the second partial screen according to the angle β collected by the magnetic angle sensor, where θ is 180- β.
Of course, the folding angle between the first partial screen and the second partial screen may also be obtained through other possible implementations, which is not specifically limited in the embodiment of the present invention.
Wherein the first partial screen and the second folded screen may be rotated along a folding axis of the terminal device.
For example, when the first partial screen is an upper half screen of the terminal device, the second partial screen is a lower half screen of the terminal device. When the first part of screen is the left half screen of the terminal device, the second part of screen is the right half screen of the terminal device.
S202, according to the folding angle, determining an audio playing mode of the terminal equipment, wherein the audio playing mode comprises a stereo mode and a monaural mode.
Optionally, the audio playing mode of the terminal device may be determined according to at least two possible implementations as follows:
one possible implementation is:
and judging whether the folding angle is larger than a preset angle, if so, setting the audio playing mode of the terminal equipment to be a stereo mode. And if not, setting the audio playing mode of the terminal equipment to be a non-stereo mode.
Alternatively, the larger the folding angle, the larger the distance between the first speaker and the second speaker.
In the practical application process, when the distance between the first loudspeaker and the second loudspeaker is larger than a certain distance, the first loudspeaker and the second loudspeaker can realize the stereo effect.
Optionally, the preset angle may be an angle corresponding to a minimum distance that enables the first speaker and the second speaker to realize a stereo effect.
For example, the preset angle may be 45 degrees, 30 degrees, etc.
Optionally, when the folding angle is greater than the preset angle, the first speaker and the second speaker may implement a stereo effect. When the folding angle is smaller than or equal to the preset angle, the first loudspeaker and the second loudspeaker cannot realize the stereo effect.
In the practical application process, the minimum distance of the stereo sound effect of the loudspeaker can be realized, and the minimum distance is related to the type, the attribute and the like of the loudspeaker.
For example, the types of speakers may include: an electrodynamic (moving coil) speaker, an electromagnetic speaker, an electrostatic (capacitive) speaker, a piezoelectric (crystal) speaker, a discharge (ion) speaker, and the like.
For example, the properties of the speaker may include: impedance, frequency, total quality factor value, effective volume, vibrational mass, etc.
As can be seen from the above, the preset angle is related to the type and properties of the first speaker, the type and properties of the second speaker, and the size of the terminal device.
Alternatively, the terminal device in which the first speaker and the second speaker are installed may be tested to determine the preset angle.
For example, the folding angle may be adjusted, and it is determined whether the first speaker and the second speaker can realize the stereo effect at each folding angle. The minimum folding angle that can cause the first speaker and the second speaker to realize the stereoscopic sound effect is determined as a preset angle.
Another possible implementation:
acquiring a first distance between a first loudspeaker and a folding shaft and a second distance between a second loudspeaker and the folding shaft; determining a third distance between the first loudspeaker and the second loudspeaker according to the first distance, the second distance and the folding angle; and setting an audio playing mode of the terminal equipment according to the third distance.
Optionally, judging whether the third distance is greater than a preset distance, wherein the preset distance is the minimum distance for realizing the stereo sound effect; if so, setting the audio playing mode of the terminal equipment to be a stereo mode; and if not, setting the audio playing mode of the terminal equipment to be a non-stereo mode.
Optionally, when the first part of screen is the upper half screen of the terminal device, the first speaker is disposed at the top end of the terminal device, the second part of screen is the lower half screen of the terminal device, and the second speaker is disposed at the bottom of the terminal device, the first distance is the distance between the top of the terminal device and the folding axis, and the second distance is the distance between the bottom of the terminal device and the folding axis.
Optionally, when the first partial screen is a left half screen of the terminal device, the first speaker is disposed on the left side of the terminal device, the second partial screen is a right half screen of the terminal device, and the second speaker is disposed on the right side of the terminal device, the first distance is a distance between the left side of the terminal device and the folding axis, and the second distance is a distance between the right side of the terminal device and the folding axis.
For example, assuming that the first distance is a, the second distance is b, and the folding angle is θ, the third distance c may be obtained by the following formula one:
it should be noted that, for the process of determining the preset distance, reference may be made to the process of determining the preset angle, which is not described in detail herein in the embodiment of the present invention.
S203, setting sound effect parameters of the first loudspeaker and the second loudspeaker according to the audio playing mode of the terminal equipment.
Optionally, the sound effect parameters may include a phase parameter, a gain parameter, a frequency response parameter, and the like.
Certainly, in the actual application process, the sound effect parameters may be set according to actual needs, and this is not specifically limited in the embodiment of the present invention.
Optionally, when the audio playing mode is the stereo mode, different phase parameters are set for the first speaker and the second speaker, so that the phase of the audio played by the first speaker is different from the phase of the audio played by the second speaker.
Optionally, when the audio playing mode is the non-stereo mode, the same phase parameter is set for the first speaker and the second speaker, so that the phase of the audio played by the first speaker is the same as the phase of the audio played by the second speaker.
When the phase of the audio played by the first loudspeaker is the same as that of the audio played by the second loudspeaker, and the distance between the first loudspeaker and the second loudspeaker is greater than the preset distance, the first loudspeaker and the second loudspeaker can realize the stereo effect.
When the phase of the audio played by the first loudspeaker is the same as that of the audio played by the second loudspeaker, the first loudspeaker and the second loudspeaker realize the non-stereo effect.
Alternatively, the parameters of the first speaker and the second speaker may be set in a Digital Signal Processor (DSP for short), respectively.
When the audio playing mode of the terminal device is determined to be the stereo mode, the phase parameters of the first speaker and the phase parameters of the second speaker may be modified in the DSP to make the settings of the first speaker different. Of course, other parameter settings of the first speaker and the second speaker may be different, and this is not particularly limited in the embodiment of the present invention.
When the audio playing mode of the terminal device is determined to be the monaural mode, the phase parameters of the first speaker and the phase parameters of the second speaker may be modified in the DSP so that the settings of the first speaker are the same. Of course, other parameters of the first speaker and the second speaker may also be set to be the same, and this is not particularly limited in the embodiment of the present invention.
It should be noted that when the audio playback mode is the non-stereo mode, any one of the two speakers may also be turned off.
According to the audio control method provided by the embodiment of the invention, in the operation process of the terminal equipment, the folding angle between the first part of screen and the second part of screen in the folding screen is obtained, the audio playing mode of the terminal equipment is determined according to the folding angle, the audio playing mode comprises a stereo mode and a monaural mode, and the sound effect parameters of the first loudspeaker and the second loudspeaker are set according to the audio playing mode of the terminal equipment. In the above process, when the folding angle is large, so that the distance between the first speaker and the second speaker satisfies the stereo playing distance, the audio playing mode of the first speaker and the second speaker can be set to be the stereo mode, and the audio which can be played by the first speaker and the second speaker can reach the stereo effect. When the folding angle is small, so that the distance between the first loudspeaker and the second loudspeaker does not satisfy the stereo playing distance, the audio playing mode of the first loudspeaker and the second loudspeaker can be set to be a non-stereo mode, and in the non-stereo mode, the waveforms of the audio played by the first loudspeaker and the second loudspeaker are the same, so that the interference between the audio played by the first loudspeaker and the second loudspeaker is reduced, and the audio playing effect is improved.
In addition to the embodiment shown in fig. 2, the embodiment shown in fig. 2 will be described in detail below with reference to the embodiment shown in fig. 3.
Fig. 3 is a flowchart illustrating a second audio control method according to an embodiment of the present invention. On the basis of the embodiment shown in fig. 2, referring to fig. 3, the method may include:
s301, acquiring a folding angle between a first partial screen and a second partial screen in the folding screen.
It should be noted that the execution process of S301 may refer to the execution process of S201, and is not described herein again.
S302, a first distance between the first loudspeaker and the folding shaft and a second distance between the second loudspeaker and the folding shaft are obtained.
Alternatively, the first distance and the second distance may be stored in a preset storage location of the terminal device. The first distance and the second distance stored in the preset storage position can be measured and stored in advance for a user.
Correspondingly, the first distance and the second distance can be directly obtained from the preset storage position.

Alternatively, the third distance may be determined by the above equation one.

If so, S305-S306 are performed.
If not, S307-S308 are executed.

S306, setting different phase parameters for the first loudspeaker and the second loudspeaker.
When the first loudspeaker and the second loudspeaker set different phase parameters, the phase of the audio played by the first loudspeaker is different from that of the audio played by the second loudspeaker. Accordingly, the audio played by the first speaker and the second speaker has a stereo effect.
S307, determining that the audio playing mode of the terminal equipment is a non-stereo mode.
And S308, setting the same phase parameters for the first loudspeaker and the second loudspeaker.
And when the first loudspeaker and the second loudspeaker set the same phase parameter, the phase of the audio played by the first loudspeaker is the same as that of the audio played by the second loudspeaker. Accordingly, the audio played by the first speaker and the second speaker does not have a stereo effect.
It should be noted that the execution processes of S305 to S308 may refer to the corresponding execution processes in 203, and are not described herein again.

After the two processed audio signals reach the encoder 403, a Digital-to-analog converter (DAC) in the codec 403 respectively performs Digital-to-analog conversion on the two audio signals to obtain a first audio signal and a second audio signal, where the first audio signal is sent to the first speaker and the second audio signal is sent to the second speaker.
