Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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 application.
As in the background art, a speaker control method in the related art has a defect of poor play-out effect after being shielded, and to solve the defect, an embodiment of the present application provides a speaker control method, and referring to fig. 1, fig. 1 shows a schematic flow diagram of a speaker control method provided by an embodiment of the present application; the electronic equipment comprises N loudspeakers, wherein N is a positive integer; the method comprises the following steps:
s100, acquiring a current volume gear and a first sound loudness received by a microphone;
wherein the first sound loudness corresponds to the target speaker; the above-described acquisition operation is performed in a case where the target speaker is in the play-out audio.
Different volume gears are divided according to the loudness of sound emitted by a loudspeaker in the electronic equipment, and each volume gear corresponds to different loudness of sound, namely different volume gears correspond to different volume sizes. The user's operation of adjusting the volume level is the operation of selecting a volume level, for example, if the user turns the volume level up by one, the volume level is also changed by one level. Optionally, the first sound gear may be determined directly according to the amplification factor of the power amplifier of the speaker, or if the volume gear information is recorded in the speaker control component in the electronic device, the recorded volume gear information may be directly read to obtain the current volume gear.
In addition, the speaker and the microphone are correspondingly arranged, where the microphone refers to a microphone corresponding to the speaker, such as a noise reduction microphone, and the first sound loudness received by the microphone is the actual sound loudness discharged by the target speaker. Electronic devices are often provided with multiple microphones. The microphones are usually distributed on the top and the bottom of the electronic device, for example, one microphone is arranged on the top and the bottom, and the number and the arrangement position of the microphones are not limited in the present application.
S200, comparing the first sound loudness with a preset sound loudness in the current sound volume gear to obtain a comparison result;
wherein the preset sound loudness corresponds to the target loudspeaker; the specific implementation of this step will be described in detail below. In this embodiment, preset sound loudness in each volume level is preset, and the preset sound loudness in the current volume level means: the loudness of sound that the speaker should theoretically output in the current volume level.
And S300, under the condition that the comparison result does not meet the preset condition, adjusting the volume of the target loudspeaker according to the comparison result so that the comparison result meets the preset condition.
According to the comparison result, whether the loudness of the sound actually output by the target loudspeaker is smaller than the loudness of the sound output theoretically can be determined, and whether the output port of the target loudspeaker is shielded or not can be further determined. Under the condition of shielding, the volume of the target loudspeaker can be increased, so that the actual external sound loudness of the target loudspeaker can reach the theoretical sound loudness in the shielding state. And, the adjusting operation may be performed in multiple times, and after the volume of the target speaker is adjusted each time, the operations of S100 to S300 may be repeated until the obtained comparison result satisfies the preset condition. Or, the volume adjustment may be performed once according to a specific rule according to the comparison result, that is, it can be ensured that the adjusted comparison result meets a preset condition, for example, the volume of the target speaker is adjusted up to a preset gear according to a difference between the first sound loudness of the target speaker and the preset sound loudness. The present application is not limited to how to adjust the volume of the target speaker.
In the embodiment of the application, in the loudspeaker playing process, the first sound loudness actually received by the microphone reflects the actual playing effect of the target loudspeaker, the preset sound loudness at the current volume level preset in the electronic device is the theoretical playing effect of the target loudspeaker, by comparing the first sound loudness with the preset sound loudness, the difference between the actual external playing effect and the theoretical external playing effect of the current target loudspeaker can be determined, when the comparison result does not meet the preset condition, the actual external playing effect of the target loudspeaker is not ideal, the output port of the target loudspeaker is shielded, the present embodiment adjusts the volume of the target speaker that is shielded according to the comparison result, therefore, even in a shielding state, the target loudspeaker can achieve the external playing effect meeting the requirements, and the external playing effect of sound is improved.
In some embodiments of the present application, N may be a positive integer greater than 1. For example, N may be 2, i.e. the electronic device comprises dual speakers. The double loudspeakers can improve the playing effect of the audio, so that the electronic equipment has stronger stereoscopic impression when playing the audio. According to the embodiment, after the output port of any one loudspeaker in the double loudspeakers is shielded, the volume of the shielded target loudspeaker can be adjusted, so that the influence on the stereo effect of the double loudspeakers is avoided.
In some embodiments of the present application, referring to fig. 2, fig. 2 is a schematic flowchart of a second speaker control method provided in the embodiments of the present application. The S200 may include:
s211, calculating a difference value between the first sound loudness and a preset sound loudness at the current sound volume level to obtain a target difference value;
s212, comparing the target difference value with a target loudness difference value in the current volume gear to obtain a comparison result;
accordingly, S300 is adjusted to S310, and S310 includes: and under the condition that the target difference value is greater than or equal to the target loudness difference value, adjusting the volume of the target loudspeaker according to the comparison result.
In this embodiment, the target difference between the first sound loudness and the preset sound loudness is directly compared with the target loudness difference, and if the target difference is greater than the target loudness difference, it indicates that the actual sound loudness of the external speaker is too low, and the volume needs to be increased. The mode of comparing by using the absolute loudness values can conveniently confirm whether each loudspeaker is shielded or not, and further ensures that the actual external playing effect of each loudspeaker reaches the corresponding ideal state.
To facilitate understanding of the solution of the present embodiment, the following two examples are explained.
Example one takes a single speaker as an example: the electronic device needs to perform a play-out test in a non-shielding state in advance, the play-out test can be performed before the electronic device leaves a factory, in the test process, the electronic device needs to collect and record absolute sound loudness received by a microphone under different volume gears, the absolute sound loudness is used as a preset volume loudness under a corresponding volume gear, for example, the preset volume loudness under a first volume gear is a1, the preset volume loudness under a second volume gear is a2, and the preset volume loudness under an nth volume gear of … is an. And then setting a target loudness difference value x under each volume level. In the actual playing process of the electronic equipment, the microphone collects the actual first sound loudness c and determines the current volume level, and if the current volume level is the nth volume level, the difference j between cn and the preset volume loudness an in the current volume level is calculated as an-cn. And j is compared with the target loudness difference value xn under the current volume gear, and if j is larger than xn, the target loudspeaker is shielded, and the volume needs to be increased.
Example two takes a dual speaker as an example: in the playback test stage, the electronic device collects and records the absolute loudness received by the microphone in different volume steps in advance, where the absolute loudness is used as the preset volume loudness in the corresponding volume step, for example, the preset volume loudness in the first volume step is a1 and b1, and the preset volume loudness in the second volume step is a2 and b2, and the preset volume loudness in the nth volume step of … is an and bn. And then setting a target loudness difference value under each volume gear, wherein the target loudness difference value corresponding to the top loudspeaker is x, and the target loudness difference value corresponding to the bottom loudspeaker is y. In the actual playing process of the electronic device, the top microphone is close to the top speaker, and the bottom microphone is close to the bottom speaker, so the loudness of sound collected by the bottom microphone mainly reflects the volume of the bottom speaker, and the top is the same. The actual first loudness of sound picked up by the top microphone is denoted c and the actual first loudness of sound picked up by the bottom microphone is denoted d. And determines the current volume step, assuming the nth volume step. Calculating the difference between cn and dn and the preset volume loudness an and bn at the current volume gear: the top difference is j-an-cn and the bottom difference is k-bn-dn. And j and k are respectively compared with the target loudness difference values xn and yn in the current volume gear, if j is larger than xn, the top loudspeaker is shielded, and if k is larger than yn, the bottom loudspeaker is shielded.
Optionally, the target loudness difference may be: loudness that is a preset percentage of the preset sound loudness. For example, a loudness of 10% of a preset sound loudness.
The target loudness difference value indicates the maximum allowable difference value between the first sound loudness when the target loudspeaker is actually played outside and the theoretical preset sound loudness, so the target loudness difference value is set on the basis of the preset sound loudness, the target loudness difference value can be changed along with the change of the volume gear, and the rationality of the target loudness difference value is improved by the setting mode of the self-adaptive change, and the playing effect of the loudspeaker is better after the adjustment based on the set target loudness difference value.

In this embodiment, a plurality of speakers are provided in the electronic device to achieve a stereo effect, and in this case, it is usually necessary to make the loudness of sound emitted from each speaker the same so that the user can feel the same sound effect at each position. Therefore, in the embodiment, the ratio of the first sound loudness of the two speakers is compared with the ratio of the preset sound loudness of the two speakers, so that after subsequent volume adjustment, the actual volume of the two speakers can be ensured to reach a balanced state, and the electronic device has a better stereo effect. At this time, the actual sound loudness of the two speakers may not be equal to the preset sound loudness.
To facilitate understanding of the aspects of the present embodiment, the following examples are explained.
Take a dual speaker as an example: in the playback test stage, the electronic device collects and records the absolute loudness received by the microphone in different volume steps in advance, where the absolute loudness is used as the preset volume loudness in the corresponding volume step, for example, the preset volume loudness in the first volume step is a1 and b1, and the preset volume loudness in the second volume step is a2 and b2, and the preset volume loudness in the nth volume step of … is an and bn. And then calculating a preset ratio en (an/bn) under different volume gears based on the preset volume loudness. During the actual playing process of the electronic device, the actual first loudness of sound collected by the top microphone is c, and the actual first loudness of sound collected by the bottom microphone is d. The first ratio is m-c/d.
In still other embodiments of the present application, referring to fig. 4, fig. 4 is a schematic flowchart of a fourth speaker control method provided in the embodiments of the present application. The S200 may include:
s231, calculating a first ratio between the second sound loudness and the third sound loudness;
s232, calculating a second ratio between the first ratio and a preset ratio;
s233, comparing the second ratio with a target ratio under the current volume gear to obtain a comparison result;
correspondingly, S300 specifically includes:
s331, under the condition that the second ratio is larger than or equal to the target ratio, adjusting the volume of the second loudspeaker according to the comparison result;
and S332, under the condition that the second ratio is smaller than the target ratio, adjusting the volume of the first loudspeaker according to the comparison result.
In this embodiment, a second ratio between the first ratio and the preset ratio is compared with the target ratio, and according to whether the second ratio meets the requirement, the relative magnitude relationship between the playback volumes of the two speakers in each group can be determined, and then the speakers to be adjusted and the adjustment strategy thereof are determined, so that the balance between the playback volumes of the two speakers in each group is ensured, and this way, the stereo effect of sound in the process of adjusting the playback of the speakers is ensured. And the comparison mode enables a user to adjust the target ratio according to the actual situation, and further achieves the purpose of selecting different volume adjustment effects according to the actual situation.
To facilitate understanding of the aspects of the present embodiment, the following examples are explained.
Take a dual speaker as an example: and setting a target ratio z under each volume gear. The current volume gear is assumed to be the nth volume gear. And calculating the ratio between the first ratio m and the preset volume loudness en at the current volume level to obtain a second ratio m/en, comparing the m/en with a target ratio z at the current volume level, and if the m/en is greater than or equal to z, indicating that m is larger, increasing the volume of the bottom loudspeaker (namely the second loudspeaker).
In still other embodiments of the present application, referring to fig. 5, fig. 5 is a schematic flowchart of a fifth speaker control method provided in the embodiments of the present application.

and S342, under the condition that the first ratio is smaller than the preset ratio, adjusting the volume of the first loudspeaker according to the comparison result.
When the first ratio is greater than or equal to the preset ratio, it indicates that the first ratio is greater, and since the first ratio is a ratio of the loudness of sound of the first speaker to the loudness of sound of the second speaker, it indicates that the loudness of sound of the first speaker is greater than the loudness of sound of the second speaker, and therefore the volume of the second speaker needs to be increased. Conversely, when the first ratio is smaller than the preset ratio, it indicates that the loudness of the sound of the first speaker is smaller than the loudness of the sound of the second speaker, and therefore, the volume of the first speaker needs to be increased.
In this embodiment, the first ratio and the preset ratio are directly compared, and because the preset ratio is used as a standard value, whether the first ratio is too large or too small can be determined based on the size relationship between the first ratio and the preset ratio, so that the volume adjustment scheme for adjusting the speaker to be adjusted can be visually determined. In this way, the loudspeaker of the electronic equipment can have the stereo play-out effect. Of course, the specific volume adjustment scheme may be set by the staff according to actual needs, which is not limited in this application.

Take a dual speaker as an example: and setting a target ratio z under each volume gear. The current volume gear is assumed to be the nth volume gear. And comparing the first ratio m with a preset sound loudness en at the current sound volume level, wherein if m is larger than en, the first sound loudness d of the current bottom microphone is lower than the preset sound loudness en at the current sound volume level, so that the sound volume of the bottom microphone can be increased.
