[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] With the development of electronic technology, electronic devices such as smart phones are used more and more frequently in users' daily life. Among them, the audio playback function of the electronic device is one of the functions that users use most in the process of using the electronic device. For example, in the process of users using the electronic device to watch movies and TV series, listen to music, play games, make voice calls or video calls, etc., the audio playback function of the electronic device will be used. Therefore, users have higher requirements for the sound effect when the electronic device plays audio. For example, when using the audio external playback function of the electronic device, the electronic device can output a stereo external playback effect through the set speaker.

[0026] However, due to the thinness and portability of the electronic device, the configuration of a single speaker has been difficult to meet the increasing demand of users for audio external playback scenarios such as loudness and surround feeling. In order to improve and improve the external playback effect of the electronic device, more and more electronic devices are equipped with two or more speakers to obtain better stereo effect. But limited by the thin body of the electronic device, and the squeezing of multiple cameras and large batteries in the electronic device to the limited internal space of the electronic device, it is difficult to integrate two completely symmetrical speakers on the electronic device to achieve good stereo effect.

[0027] The configuration of the current main process is generally to set a slightly weaker speaker above the electronic device to realize the receiver function of the handheld microphone, and set a better speaker below the electronic device to assist in outputting the stereo sound effect. Based on the configuration of the current electronic device speaker system, in most external playback scenarios, the optimal performance of the better speaker often needs to be reduced to balance the stereo sound effect. Generally, when adjusting the performance of the speaker, the volume key of the electronic device is adjusted. When adjusting the volume key of the electronic device, the performance of the two speakers provided in the electronic device is often adjusted synchronously, and there is always an asymmetric listening experience of "upper weak and lower strong", and the user experience is poor. Among them, when adjusting the volume key of the electronic device, the performance of the two speakers provided in the electronic device is often adjusted synchronously, that is, the performance of the two speakers provided in the electronic device is simultaneously increased or decreased with the adjustment of the volume key; the asymmetric listening experience of "upper weak and lower strong" is due to the weaker performance of the speaker provided above the electronic device, and the better performance of the speaker provided below the electronic device.

[0028] Therefore, the inventors propose the speaker control method, device, electronic device and storage medium in the present application. In the case that the performance of the second speaker is higher than the preset performance, in response to the change of the volume level, the volume output by the first speaker remains unchanged, and the volume output by the second speaker changes with the change of the volume level. Through the above method, in the case that the performance of the second speaker exceeds the preset performance, in response to the change of the volume level, the output of the first speaker remains constant, and the performance of the second speaker is fully improved, so that the first speaker and the second speaker can output balanced stereo effect, and the user experience is improved.

[0029] The application environment of the speaker control method provided by the present application is introduced as follows:

[0030] Please refer to Figure 1 The speaker control method provided by the present application can be applied to the electronic device 100 as shown in Figure 1 The electronic device 100 can include two or more speakers. For example, Figure 1As shown, the electronic device 100 can include two speakers, a first speaker 110 and a second speaker 120. The performance of the first speaker 110 and the second speaker 120 can be the same or different. Optionally, the performance of the first speaker 110 can be higher than that of the second speaker 120; the performance of the first speaker 110 can also be lower than that of the second speaker 120; or the performance of the first speaker 110 can be equal to that of the second speaker 120. When the performance of the first speaker 110 is equal to that of the second speaker 120, balanced stereo sound can be output through the first speaker 110 and the second speaker 120. Therefore, in the case where the performance of the first speaker 110 and the second speaker 120 is different, in order to output balanced stereo sound and provide a good sound experience for the user, the performance of the first speaker 110 or the second speaker 120 can be adjusted so that balanced stereo sound can be output through the first speaker 110 and the second speaker 120 after adjustment.

[0031] In the embodiments of the present application, the first speaker 110 and the second speaker 120 can each have two terminal posts (two leads), and the two leads have no positive and negative polarity when only the first speaker 110 or the second speaker 120 is used in the electronic device 100; the two leads have polarity when the first speaker 110 and the second speaker 120 are used simultaneously in the electronic device 100.

[0032] In the embodiments of the present application, as shown in Figure 1 In the electronic device 100, the first speaker 110 can be arranged at the upper end of the electronic device 100, and the second speaker 120 can be arranged at the lower end of the electronic device 100, and the first speaker 110 and the second speaker 120 can be driven to operate by separate smart power amplifiers (Smart PA), such as a smart power amplifier 1 driving the first speaker 110 to operate and a smart power amplifier 2 driving the second speaker 120 to operate.

[0033] The smart power amplifier generally adopts a full-bridge inverter circuit. The full-bridge inverter circuit of the smart power amplifier can refer to Figure 2 , which includes four switching tubes Q1, Q2, Q3 and Q4, and each switching tube has an input end and an output end connected to a diode. The input ends of the switching tubes Q1 and Q3 are connected to a direct current voltage VBOOST, and the output ends of the switching tubes Q2 and Q4 are grounded. The common end of the switching tubes Q1 and Q2 is the SPK-P end, the common end of the switching tubes Q3 and Q4 is the SPK-N end, and the SPK-P end and the SPK-N end are connected to the speaker.

[0034] Figure 2The switch tubes Q1 to Q4 shown in the figure are NPN transistors, the input end refers to the collector of the NPN transistor, the output end refers to the emitter of the NPN transistor, and the control end refers to the base of the NPN transistor. However, the switch tubes Q1 to Q4 can also use other forms of switch tubes.

[0035] Optionally, in the smart power amplifier, the four switch tubes are turned on in time to provide voltage for the speaker to run. Specifically, as shown in the figure, in the first stage, the switch tubes Q1 and Q4 are turned on, the switch tubes Q2 and Q3 are turned off, and the direct current voltage VBOOST supplies power to the speaker in the direction indicated by ①. In the second stage, the switch tubes Q1 and Q4 are turned off, the switch tubes Q2 and Q3 are turned on, and the direct current voltage VBOOST supplies power to the speaker in the direction indicated by ②. Figure 3

[0036] It should be noted that the electronic device 100 can be not only the smart phone shown in the figure, but also a car machine device, a wearable electronic device, a tablet computer, a (desktop, laptop) notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a personal digital assistant (PDA), a smart speaker, and the like, which can be configured with two or more speakers. Figure 1

[0037] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Please refer to Figure 4 , the speaker control method provided by the embodiments of the present application is applied to an electronic device as shown in the figure, and the method comprises the following steps. Figure 1

[0039] Step S110: in the case where the performance of the second speaker is higher than the preset performance, the volume output by the first speaker is kept unchanged in response to the change of the volume level.

[0040] In the embodiments of the present application, the electronic device comprises a first speaker and a second speaker. The first speaker and the second speaker are asymmetric speakers.

[0041] In the embodiments of the present application, the first speaker and the second speaker are asymmetric speakers, which means that the optimal performance of the first speaker and the second speaker is different. Optionally, the first speaker is the speaker with lower performance in the two speakers, and the second speaker is the speaker with higher performance in the two speakers, that is, in the embodiments of the present application, the optimal performance of the first speaker is lower than that of the second speaker.

[0042] ​​​As a way, the loudspeaker is the key part in the loudspeaker system, and the sound quality of the loudspeaker is mainly determined by the performance index of the loudspeaker. In the embodiments of the present application, the performance of the loudspeaker can be represented by the numerical value of the performance index of the loudspeaker. The performance index of the loudspeaker can include rated power, rated impedance, frequency characteristic, harmonic distortion, sensitivity, directivity, etc.

[0043] Among them, the rated power of the loudspeaker refers to the output power of the loudspeaker that can work for a long time, also known as the undistorted power, which is generally marked on the back end of the loudspeaker. When the loudspeaker works at the rated power, the voice coil will not produce overheating or mechanical overload, and the sound emitted will not show distortion. The rated power is an average power, and in fact the loudspeaker works in a variable power state, which changes with the strength of the input audio signal. In weak music and sound signals, the peak pulse signal can exceed the rated power by many times, and since the duration is short, the loudspeaker will not be damaged, but distortion may occur. Therefore, in order to ensure that the sound quality can be well obtained when the peak pulse occurs, the loudspeaker must have sufficient power margin. Generally, the maximum power that the loudspeaker can follow is 24 times the rated power.

[0044] The rated impedance of the loudspeaker refers to the ratio of the voltage applied to the input end of the loudspeaker to the current flowing through the loudspeaker under the rated state of the loudspeaker. At present, the rated impedance of the loudspeaker generally has several kinds of 2, 4, 8, 16, 32 ohms. The rated impedance of the loudspeaker is measured under the condition of inputting a 400Hz signal voltage.

[0045] The frequency characteristic of the loudspeaker is an index for measuring the bandwidth of the loudspeaker. High-fidelity sound system requires that the loudspeaker system should be able to replay the human ear audible frequency range of 10Hz-2000Hz. Since it is not easy to achieve this frequency range with a single loudspeaker, currently high-fidelity sound box system adopts high, medium and low three kinds of loudspeakers to realize full frequency band playback coverage. In addition, the frequency characteristic of the high-fidelity loudspeaker should be as flat as possible, otherwise it will introduce frequency distortion in playback. High-fidelity sound system requires that the frequency characteristic of the loudspeaker should be less than 10dB in the frequency range of the sound.

[0046] There are many kinds of distortion of the loudspeaker, the common ones are harmonic distortion (often caused by uneven magnetic field of the loudspeaker and distortion of the vibration system, often produced at low frequency), intermodulation distortion (because two signals of different frequencies are added to the loudspeaker at the same time, the quality of the modulated audio is deteriorated) and transient distortion (because the inertia of the vibration system cannot follow the change of the signal, the signal is distorted) etc. The harmonic distortion of the loudspeaker refers to the increase of the harmonic components in the original signal during playback. The harmonic distortion of the loudspeaker is caused by uneven magnetic field of the magnet, non-linear distortion of the vibration membrane, voice coil displacement, etc. The harmonic distortion index of the current better loudspeaker is not more than 5%.

[0047] The sensitivity of a loudspeaker generally refers to the sound pressure measured at 1 m in front of the loudspeaker axis when the input power is 1 W. The sensitivity is an index for measuring whether the loudspeaker can replay the details in the audio signal in great detail. The higher the sensitivity of the loudspeaker, the more details in the audio signal can be responded by the loudspeaker. The sensitivity of the HiFi loudspeaker should be greater than 86 dB / W.

[0048] The sound pressure frequency characteristics of the loudspeaker radiation in different directions are different, and such characteristics become the directivity of the loudspeaker. The directivity of the loudspeaker is related to the aperture of the loudspeaker. When the aperture of the loudspeaker is large, the directivity of the loudspeaker is sharp, and when the aperture of the loudspeaker is small, the directivity of the loudspeaker is wide. The directivity of the loudspeaker is also related to the frequency. Generally speaking, there is no obvious directivity for low-frequency signals below 250 Hz, and there is obvious directivity for high-frequency signals below 1.5 kHz.

[0049] In the embodiments of the present application, the preset performance can be the optimal performance of the loudspeaker with weaker performance in the two loudspeakers. The optimal performance can be the maximum value of any one of the performance indicators, or different values set for the different performance indicators after comprehensive evaluation of the performance indicators. For example, if the optimal performance of the first loudspeaker is lower than that of the second loudspeaker, the preset performance can be the optimal performance of the first loudspeaker. Specifically, the maximum rated power of the first loudspeaker can be set as the preset performance, or the value obtained by weighted summation of the performance characteristics corresponding to the first loudspeaker can be set as the preset performance, which is not limited here.

[0050] Optionally, the preset performance can also be determined by modeling, matching the performance balance point of the first loudspeaker and the second loudspeaker, and taking the performance corresponding to the performance balance point as the preset performance. Specifically, the optimal performance of the first loudspeaker and the adjustment of the second loudspeaker to the performance close to the performance balance point are determined as the preset performance.

[0051] When the preset performance is determined by modeling, since the optimal performance of the first loudspeaker is lower than that of the second loudspeaker, the performance of the first loudspeaker and the second loudspeaker can be adjusted to the respective optimal performance first, the optimal performance of the first loudspeaker is kept unchanged, and then the performance of the second loudspeaker is gradually reduced to find the performance balance point of the first loudspeaker and the second loudspeaker, so that the performance corresponding to the performance balance point is determined as the preset performance.

[0052] Further, for most users, when using the audio externalization function of the electronic device, in a relatively quiet environment, more attention is paid to the quality of the sound, that is, the sound emitted by the loudspeaker needs to be balanced and clear and comfortable; and in a noisy environment, the volume key is often adjusted to the maximum, and greater loudness is needed to meet the user's demand for obtaining the sound content of the externalization of the electronic device, and the demand for sound balance and sound quality is reduced. In order to improve the asymmetric stereo effect and improve the externalization effect of the electronic device, two intelligent power amplifiers can be used to drive the first loudspeaker and the second loudspeaker to work respectively, and separate volume curve configurations are set for the first loudspeaker and the second loudspeaker, so that when the user adjusts the volume key, the first loudspeaker and the second loudspeaker are switched from synchronous change to separate change, so that the first loudspeaker and the second loudspeaker individually reduce or maintain the output effect with the change of the volume key, thereby enabling the asymmetric loudspeakers to output balanced stereo effect in most scenarios. That is, when it is detected that the user adjusts the volume key, according to the adjustment of the volume key, the volume of the first loudspeaker is adjusted to the volume corresponding to the corresponding volume level in the corresponding volume curve of the first loudspeaker through the volume curve configuration corresponding to the first loudspeaker; and the volume of the second loudspeaker is adjusted to the volume corresponding to the corresponding volume level in the corresponding volume curve of the second loudspeaker through the volume curve configuration corresponding to the second loudspeaker.

[0053] In the embodiments of the present application, the volume curve configurations corresponding to the first loudspeaker and the second loudspeaker are different. The volume curve is used to represent the linear relationship between the volume level and the volume size. The adjustment of the volume key corresponds to the volume level, and each level in the volume level corresponds to one adjustment of the volume key. That is, the volume key is adjusted once, and the volume level is changed once.

[0054] For example, as shown in FIG. 1, Figure 5 , the volume curve configurations corresponding to the first loudspeaker and the second loudspeaker are different. The volume curve is used to represent the linear relationship between the volume level and the volume size. The adjustment of the volume key corresponds to the volume level, and each level in the volume level corresponds to one adjustment of the volume key. That is, the volume key is adjusted once, and the volume level is changed once. Figure 5 Figure 5 In the embodiments of the present application, the volume curve configurations corresponding to the first loudspeaker and the second loudspeaker are different. The volume curve is used to represent the linear relationship between the volume level and the volume size. The adjustment of the volume key corresponds to the volume level, and each level in the volume level corresponds to one adjustment of the volume key. That is, the volume key is adjusted once, and the volume level is changed once. Figure 5 Figure 5 In the embodiments of the present application, the volume curve configurations corresponding to the first loudspeaker and the second loudspeaker are different. The volume curve is used to represent the linear relationship between the volume level and the volume size. The adjustment of the volume key corresponds to the volume level, and each level in the volume level corresponds to one adjustment of the volume key. That is, the volume key is adjusted once, and the volume level is changed once. Figure 5

[0055] ​​​As a manner, when the performance of the second speaker is detected to be higher than the preset performance, and the performance of the first speaker is at the highest performance, if the change of the volume level number is detected, the volume output by the first speaker is kept unchanged. That is, when the performance of the first speaker and the performance of the second speaker are both detected to be higher than the performance corresponding to the performance balance point, the performance of the first speaker is controlled to be kept unchanged. Whether the increase of the volume level number is detected or the decrease of the volume level number is detected, the performance of the first speaker is kept unchanged.

[0056] Step S120: simultaneously control the volume output by the second speaker to change with the change of the volume level number.

[0057] In the embodiment of the present application, when the change of the volume level number is detected, the volume output by the second speaker is controlled to change with the change of the volume level number. Specifically, if the increase of the volume level number is detected, the volume output by the second speaker is controlled to increase; if the decrease of the volume level number is detected, the volume output by the second speaker is controlled to decrease. Through the above manner, the balanced output of the first speaker and the second speaker can be ensured as much as possible, and the performance of the second speaker can be fully played at a large volume to improve the overall loudness to meet the user demand.

[0058] The speaker control method provided in the present application, in the case that the performance of the second speaker is higher than the preset performance, the volume output by the first speaker is controlled to be kept unchanged in response to the change of the volume level number, and the volume output by the second speaker is controlled to change with the change of the volume level number. Through the above method, in the case that the performance of the second speaker exceeds the preset performance, the output of the first speaker is controlled to be kept constant in response to the change of the volume level number, and the performance of the second speaker is fully improved, so that the first speaker and the second speaker can output balanced stereo sound effect, and the user experience is improved.

[0059] Please refer to Figure 6 The speaker control method provided in the embodiment of the present application is applied to the electronic device as shown in Figure 1 The method comprises the following steps:

[0060] Step S210: in the case that the performance of the second speaker is lower than the preset performance, the volume output by the first speaker and the volume output by the second speaker are controlled to change synchronously with the change of the volume level number in response to the change of the volume level number.

[0061] In the embodiment of the present application, if the performance of the second speaker is detected to be lower than the preset performance, and the performance of the first speaker is also lower than the preset performance, the volume output by the first speaker and the volume output by the second speaker are controlled to change synchronously with the change of the volume level number in response to the change of the volume level number.

[0062] As a manner, the volume outputted by the first speaker and the volume outputted by the second speaker are controlled to change synchronously with the change of the volume level, including: controlling the volume outputted by the first speaker and the volume outputted by the second speaker to attenuate by the same amplitude with the decrease of the volume level; or, controlling the volume outputted by the first speaker and the volume outputted by the second speaker to increase by the same amplitude with the increase of the volume level.

[0063] That is to say, in the above case, if the volume level is detected to decrease, the volume outputted by the first speaker and the volume outputted by the second speaker are decreased simultaneously; if the volume level is detected to increase, the volume outputted by the first speaker and the volume outputted by the second speaker are increased simultaneously.

[0064] The speaker control method provided by the application can control the volume outputted by the first speaker and the volume outputted by the second speaker to change synchronously with the change of the volume level in response to the change of the volume level when the performance of the second speaker is lower than the preset performance. By the above method, when the performance of the second speaker is lower than the optimal performance of the first speaker, the volume outputted by the first speaker and the volume outputted by the second speaker can be controlled to change synchronously, so that the first speaker and the second speaker can output balanced stereo sound effect, and the user experience can be improved.

[0065] Please refer to Figure 7 The speaker control method provided by the embodiment of the application is applied to an electronic device as shown in Figure 1 The method comprises the following steps.

[0066] Step S310: obtaining the optimal performance of the first speaker.

[0067] Step S320: taking the optimal performance as the preset performance.

[0068] In the embodiment of the application, the optimal performance of the first speaker can be directly taken as the preset performance.

[0069] Step S330: when the performance of the second speaker is higher than the preset performance, in response to the change of the volume level, the first speaker is driven to work by the first power amplifier, so as to control the volume outputted by the first speaker to remain unchanged.

[0070] In the embodiment of the application, in order to improve the sound output effect of the electronic device, two power amplifiers can be used to drive different speakers to work. Specifically, as shown in Figure 8 Figure 8 ​A schematic diagram of a driving circuit in an embodiment of the present application is shown. In the embodiment of the present application, the driving circuit can include a microcontroller unit (MCU), a first power amplifier (PA1), a second power amplifier (PA2), a first speaker (SPK1), and a second speaker (SPK2). The microcontroller unit can address the first power amplifier (PA1) and the second power amplifier (PA2) through an I2C bus, respectively. Meanwhile, the microcontroller unit can connect the first power amplifier (PA1), the second power amplifier (PA2), the first speaker (SPK1), and the second speaker (SPK2) through an Inter-IC Sound (I2S) bus. As shown in FIG. 1, the microcontroller unit, the first power amplifier (PA1), and the first speaker (SPK1) form a path to drive the first speaker (SPK1) through the first power amplifier (PA1); and the microcontroller unit, the second power amplifier (PA2), and the second speaker (SPK2) form a path to drive the second speaker (SPK2) through the second power amplifier (PA2). Figure 9

[0071] In the embodiment of the present application, the first power amplifier and the second power amplifier are configured with separate volume curves to provide different audio parameters for the speakers in different scenarios and provide better sound effects for users.

[0072] As a way, when the first speaker is driven to work through the first power amplifier to control the volume output by the first speaker to remain unchanged, the first power amplifier can be controlled to drive the first speaker to work at a constant power, so as to control the volume output by the first speaker to remain unchanged.

[0073] Step S340: simultaneously driving the second speaker to work through the second power amplifier to control the volume output by the second speaker to change with the change of the volume level.

[0074] In the embodiment of the present application, when the second speaker is driven to work through the second power amplifier to control the volume output by the second speaker to change with the change of the volume level, the second power amplifier can be controlled to drive the second speaker to work at different powers, so as to control the second speaker to output different sizes of volumes at different powers.

[0075] ​The speaker control method provided in the application first acquires the optimal performance of the first speaker, takes the optimal performance as the preset performance, and then in the case that the performance of the second speaker is higher than the preset performance, the first speaker is driven to work by the first power amplifier to control the volume output by the first speaker to remain unchanged, and the second speaker is driven to work by the second power amplifier to control the volume output by the second speaker to change with the change of the volume level, in response to the change of the volume level. Through the above method, different power amplifiers are used to drive different speakers, so that sufficient driving capability can be ensured when the external playing function of the electronic device is used, and the optimal system sound effect is ensured. Furthermore, in the case that the performance of the second speaker exceeds the preset performance, the output of the first speaker is controlled to remain constant, and the performance of the second speaker is fully improved, so that the first speaker and the second speaker can output balanced stereo sound effect, and the user experience is improved.

[0076] Please refer to Figure 9 The speaker control method provided in the embodiments of the application is applied to an electronic device as shown in Figure 1 The method comprises the following steps:

[0077] Step S410: Acquire the current external playing scene.

[0078] In the embodiments of the application, the requirements of the user on the stereo sound effect are different in different external playing scenes, so different audio parameters can be set for different external playing scenes in advance to meet the different requirements of the user on the stereo sound effect in different external playing scenes.

[0079] As a kind of way, the external playing scene can include listening to music scene, watching video scene, making a phone call scene and the like, which are not limited herein. Each external playing scene can be associated with a certain application program in the electronic device, so the current external playing scene can be determined by detecting the application program running in the electronic device. For example, the watching video scene can be associated with the video playing application program in the electronic device, so whether the current scene is the video playing scene can be determined by detecting whether the video playing application program is running in the electronic device.

[0080] Optionally, different scene identifiers can be set for different external playing scenes, and then the current external playing scene can be determined by determining whether the corresponding application identifier is detected.

[0081] Of course, the way of determining the current external playing scene can be executed when it is detected that the electronic device is in the external playing mode.

[0082] In the embodiments of the present application, a target control can be arranged in the electronic device, which is used to control whether the electronic device switches to the external mode. When the target control is detected in the first state, it is determined that the electronic device is in the external mode, and when the target control is detected in the second state, it is determined that the electronic device is not in the external mode. The first state represents that the target control is in the running state, and the second state represents that the target control is in the idle state.

[0083] Step S420: Obtain the audio parameter corresponding to the external scene.

[0084] In the embodiments of the present application, the audio parameter can include the number of channels, the number of quantization bits, the sampling frequency, the code rate, and the like. In different external scenes, the values of the above audio parameters can be set differently.

[0085] As a way, the correspondence between the external scene and the audio parameter can be established in advance, and then after the current external scene is determined, the corresponding audio parameter can be determined through the correspondence.

[0086] Step S430: In the case where the performance of the second loudspeaker is higher than the preset performance, in response to the change of the volume level number, the first loudspeaker is driven by the first power amplifier to work at the audio parameter based on the audio parameter, so as to control the volume output by the first loudspeaker to remain unchanged.

[0087] In the embodiments of the present application, after the audio parameter corresponding to the current external scene is determined, the first loudspeaker can be driven by the first power amplifier to work at the audio parameter, and in the case where the performance of the second loudspeaker is higher than the preset performance, in response to the adjustment of the volume key, the volume output by the first loudspeaker is controlled to remain unchanged.

[0088] Step S440: At the same time, the second loudspeaker is driven by the second power amplifier to work at the audio parameter based on the audio parameter, so as to control the volume output by the second loudspeaker to change with the change of the volume level number.

[0089] In the embodiments of the present application, after the audio parameter corresponding to the current external scene is determined, the second loudspeaker can be driven by the second power amplifier to work at the audio parameter, and in the case where the performance of the second loudspeaker is higher than the preset performance, in response to the adjustment of the volume key, the volume output by the second loudspeaker is controlled to dynamically change with the adjustment of the volume key.

[0090] The loudspeaker control method provided in the application first acquires a current external playing scene, and then acquires an audio parameter corresponding to the external playing scene, so that in the case that the performance of the second loudspeaker is higher than the preset performance, the first loudspeaker is driven to work with the audio parameter by the first power amplifier based on the audio parameter in response to the change of the volume level, so as to control the volume output by the second loudspeaker to remain unchanged, and the second loudspeaker is driven to work with the audio parameter by the second power amplifier based on the audio parameter, so as to control the volume output by the second loudspeaker to change with the change of the volume level. In the above manner, the loudspeaker is controlled to work through different audio parameters in different external playing scenes, so that the sound effect in different external playing scenes can be guaranteed. Furthermore, in the case that the performance of the second loudspeaker exceeds the preset performance, the output of the first loudspeaker is controlled to remain constant in response to the change of the volume level, and the performance of the second loudspeaker is fully improved, so that the first loudspeaker and the second loudspeaker can output balanced stereo sound effect, and the user experience is improved.

[0091] Please refer to Figure 10 The loudspeaker control method provided in the embodiments of the application is applied to an electronic device as shown in Figure 1 The method comprises the following steps.

[0092] Step S510: Acquire a current external playing scene.

[0093] Step S520: Acquire an audio parameter corresponding to the external playing scene.

[0094] Step S530: In the case that the performance of the second loudspeaker is lower than the preset performance, the first loudspeaker is driven to work with the audio parameter by the first power amplifier based on the audio parameter in response to the change of the volume level, and the second loudspeaker is driven to work with the audio parameter by the second power amplifier, so as to control the volume output by the first loudspeaker and the volume output by the second loudspeaker to change synchronously with the change of the volume level.

[0095] In the embodiments of the application, after the audio parameter corresponding to the current external playing scene is determined, the first loudspeaker is driven to work with the audio parameter by the first power amplifier, and the second loudspeaker is driven to work with the audio parameter by the second power amplifier.

[0096] In the case that the performance of the second loudspeaker is lower than the preset performance, the volume output by the first loudspeaker and the volume output by the second loudspeaker are controlled to change with the adjustment of the volume key.

[0097] The application provides a loudspeaker control method, which comprises the following steps: acquiring a current external playing scene; and acquiring audio parameters corresponding to the external playing scene. In the case that the performance of a second loudspeaker is lower than a preset performance, the volume output by a first loudspeaker and the volume output by the second loudspeaker are controlled to change synchronously with the change of the volume level in response to the change of the volume level. Through the above method, in the case that the performance of the second loudspeaker is lower than the optimal performance of the first loudspeaker, the volumes output by the first loudspeaker and the second loudspeaker are controlled to change synchronously, so that the first loudspeaker and the second loudspeaker can output balanced stereo sound effect, and the user experience is improved.
