In some embodiments, the detection circuit 120 is embodied as a Smart Power Amplifier (Smart PA), which may include two monitoring circuits, i.e., a current (I) monitoring circuit and a voltage (V) monitoring circuit, for detecting the states of at least two speakers.

The electronic device provided in fig. 1 may perform the method/steps illustrated in fig. 2, and the detailed description process refers to fig. 2.
Fig. 2 is a flowchart of a method for adjusting volume according to an embodiment of the present invention. As shown in fig. 2, the main body of the method 200 may be the electronic device 100 shown in fig. 1, and the method 200 may include the following steps:
s210, detecting at least two loudspeakers, and determining a frequency resonance point and a volume amplitude value of each loudspeaker.
Specifically, the state of each Speaker (Speaker) can be detected by using a detection mechanism provided by a smart power amplifier (SmartPA), and a spectrum fed back by each Speaker can be obtained, where the spectrum may include the volume of the Speaker playing, and more specifically, a current value and a voltage value of the audio feedback played by each Speaker can be obtained by using two monitoring circuits of current (I) and voltage (V) in the existing SmartPA, which needs to be mentioned that detection by recording through a microphone is not needed. SmartPA acquires the current value and the voltage value of each loudspeaker in real time, and determines a frequency resonance point (frequency resonance point) and a volume amplitude value corresponding to a Speaker through a preset built-in algorithm, wherein in the invention, the frequency resonance point is abbreviated as F0.
It should be noted that the built-in algorithm in the embodiment of the present invention may be an algorithm provided by different providers, and the frequency resonance point and the volume amplitude value of the speaker may be obtained by calculating according to the obtained current value and voltage value of the speaker.
And S220, determining the state of each loudspeaker according to the frequency resonance point of each loudspeaker.
In the embodiment of the present invention, the state of the speaker may include a state in which the speaker is blocked or blocked by an object, a state in which the speaker is normally used or not used, and the like.
The electronic device may determine that the speaker is blocked or clogged by the foreign object when the frequency resonance point F0 of the speaker is out of the preset condition range of the preset frequency resonance point, that is, the fluctuation of the frequency resonance point F0 of the speaker from the preset frequency writing point is out of a certain range, according to the comparison between the frequency resonance point F0 of the speaker used and the frequency resonance point of each speaker of the preset values.
And S230, when a first loudspeaker of the at least two loudspeakers is in the first state, adjusting the volume of the first loudspeaker according to the volume amplitude values of the at least two loudspeakers.
Specifically, in some embodiments of the present invention, the first state represents a state in which the speaker is blocked or clogged by a foreign object. The blocked loudspeaker may be one, two or more, i.e. the first loudspeaker may be one, two or more of the at least two loudspeakers. The electronic device may adjust the volume of the blocked speaker according to the volume amplitude value of the blocked speaker, or adjust the volume of the speaker according to the volume amplitude value of the blocked speaker and the volume amplitude values of one, two, or more other unblocked speakers, for example, the volume of the blocked or blocked speaker may be adjusted to be larger, so that the adjusted volume levels heard by the user are balanced.
In some embodiments, the determining the frequency resonance point and the volume amplitude value of each speaker, the step S220 and the step S230 may be specifically performed by a dedicated processor or a processor (usually a DSP) of Smart PA itself, or may be performed by a CPU. These steps may be performed by one processor or by different processors. For example, determining the frequency resonance point and the volume amplitude value of each speaker is performed by a dedicated processor or a Smart PA-owned processor, and steps S220 and S230 are performed by a CPU; alternatively, the determination of the frequency resonance point and the volume amplitude value of each speaker and the step S220 are performed by a dedicated processor or a Smart PA-owned processor, and the step S230 is performed by a CPU; or determining the frequency resonance point and the volume amplitude value of each speaker, step S220 and step S230 are all performed by a dedicated processor or a Smart PA-resident processor (usually a DSP); or determining the frequency resonance point and the volume amplitude value of each speaker, step S220 and step S230 are performed by the CPU. Those skilled in the art will appreciate that the above embodiments are merely examples and that other combinations may be used by those skilled in the art to implement the above steps.
According to the volume adjusting method provided by the embodiment of the invention, whether each loudspeaker is in the blocked state or not is determined by detecting the states of at least two loudspeakers which are started currently, and when one, two or more loudspeakers in the at least two loudspeakers are in the blocked state, the volumes of the loudspeakers are respectively adjusted to enable the volumes of the at least two loudspeakers to be in the balanced state, so that the volumes of the at least two loudspeakers are respectively adjusted, and the user experience is improved.
Optionally, as another embodiment of the present invention, as shown in fig. 4, before adjusting the volume of the first speaker according to the volume amplitude values of the at least two speakers, the method 200 may further include:
s240, searching whether there is an adjustment mode that is the same as the current first speaker in the first state in the stored adjustment modes.
And S250, when the adjustment mode which is the same as the current first loudspeaker in the first state exists in the stored adjustment modes, adjusting the volume of the first loudspeaker by using the stored adjustment mode.
Specifically, in the embodiment of the present invention, the state that the speaker is blocked or plugged before and the adjusted volume adjustment mode of each blocked or plugged speaker may be stored, and when the SmartPA detects that the speaker is in the blocked or plugged state, whether the volume adjustment mode of each speaker, which is the same as the state mode that the SmartPA detects that the speaker is blocked currently, exists in the stored adjustment modes may be queried, so as to directly adjust the volume of each speaker according to the stored adjustment modes.
It should be noted that, in the embodiment of the present invention, the stored adjustment modes may include a state in which each speaker is used, whether each speaker is in a blocked or blocked state, and an adjusted volume (all values related to volume adjustment) of the blocked or blocked speaker.
By the method and the device, the adjustment time can be saved, the power consumption is reduced, and the user experience is further improved.
Optionally, as another embodiment of the present invention, as shown in fig. 3, after adjusting the volume of the first speaker according to the volume amplitude values of the at least two speakers, the method 200 may further include:
and S260, determining whether the adjusted volume amplitude values of the at least two loudspeakers are consistent.
Specifically, in the embodiment of the present invention, the electronic device determines the adjusted volume of one, two, or more blocked or plugged speakers, and more specifically, determines whether the adjusted volume amplitude value of the blocked or plugged speaker is consistent with the volume amplitude value of the unblocked or plugged speaker by comparing the adjusted volume amplitude value of the blocked or plugged speaker with the volume amplitude value of the unblocked or plugged speaker, and if so, the adjusted volume of at least two speakers is balanced, and the volume of the speakers heard by the user is balanced.
It should be noted that, in the embodiment of the present invention, when the difference between the adjusted volume amplitude value of the shielded or blocked speaker and the volume amplitude value of the unshielded or blocked speaker is within a certain range, if the difference is within a preset range, it is considered that the adjusted volumes of at least two speakers are balanced. However, in the embodiment of the present invention, no limitation is imposed thereon.
S270, when the adjusted volume amplitude values of the at least two speakers are not consistent, whether the volume of the first speaker is adjusted to the maximum value or not is determined.
Specifically, when the sound volume of the speaker is actually designed, each speaker needs to be set to a maximum sound volume. When the loudspeaker plays audio data such as video, audio and the like, the volume of the loudspeaker can be determined according to the self setting of the loudspeaker, the volume adjusted by a user and the volume of the audio data.
In the embodiment of the present invention, when the volume amplitude value of the blocked or plugged speaker after adjustment is inconsistent with the volume amplitude value that is not blocked or plugged, it is determined whether the volume of each adjusted speaker is adjusted to the maximum value of the played volume, so as to determine whether adjusting the blocked or plugged speaker can adjust the volumes of at least two speakers to be equal.
S280, when the volume of the first loudspeaker is not adjusted to the maximum value, the volume of the first loudspeaker is continuously adjusted, and whether the volume amplitude values of at least two loudspeakers after adjustment are consistent or not is determined.
When the volume of the adjusted shielded or blocked speaker is determined not to be adjusted to the maximum volume value, it is described that the volume of the at least two speakers can be equalized by adjusting the shielded or blocked speaker, and then the volume of the shielded or blocked speaker is continuously adjusted, and whether the volume amplitude values of the at least two speakers after the adjustment are consistent or not is performed again.
Optionally, as another embodiment of the present invention, as shown in fig. 3, the method 200 may further include:
and S290, when the volume of the first loudspeaker is adjusted to the maximum value, adjusting the volumes of other loudspeakers except the first loudspeaker in the first state, and determining whether the adjusted volume amplitude values of at least two loudspeakers are consistent.
Specifically, in the embodiment of the present invention, the volume of the speaker that is not blocked or blocked may be adjusted, for example, the volume may be turned down, so as to equalize the volumes of at least two speakers.
Optionally, as another embodiment of the present invention, as shown in fig. 3, the method 200 may further include:
and S291, when the adjusted volume amplitude values of the at least two speakers are consistent, recording the first state of the first speaker and the volume of each speaker after the volume adjustment of the at least two speakers.
In the judgment of S260, when the volume amplitude value of the speaker that is blocked or plugged after adjustment is consistent with the volume amplitude value of the speaker that is not blocked or plugged, the state of at least one speaker that is blocked or plugged by a foreign object at present and the volume that is blocked or plugged after adjustment of the speaker are recorded, so that when the current state appears again, the adjustment is directly performed according to the recorded states of the speakers and the adjusted volume, thereby improving the user experience.
Optionally, as another embodiment of the present invention, as shown in fig. 3, the method 300 may further include:
s292, when the at least two speakers are in the second state, determining whether the at least two speakers are in the first state before being in the second state.
The second state is a normal use state. When at least two used loudspeakers are in a normal use state, judging whether one or more loudspeakers in a state before the current normal use state are in a state of being shielded or blocked by foreign objects.
And when the at least two loudspeakers are in the normal use state before the current normal use state, continuing to perform the real-time monitoring on the states of the at least two loudspeakers.
S293, when the at least two speakers are in the first state before being in the second state, restoring the at least two speakers to the initial state.
When one, two or more speakers are in a state of being blocked or blocked by foreign objects before the current normal use state of the at least two speakers, the volume of the at least two speakers is reduced to the initial state set by the device, or the volume set by the factory of the device.
According to the volume adjusting method provided by the embodiment of the invention, whether each loudspeaker is in the blocked state or not is determined by detecting the states of at least two loudspeakers which are started currently, and when one, two or more loudspeakers in the at least two loudspeakers are in the blocked state, the volumes of the loudspeakers are respectively adjusted to enable the volumes of the at least two loudspeakers to be in the balanced state, so that the volumes of the at least two loudspeakers are respectively adjusted, and the user experience is improved. Meanwhile, the volume is adjusted through the stored adjusting mode, so that the adjusting time is saved, the power consumption is reduced, and the user experience is further improved.
It should be understood that, in various embodiments of the present invention, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
