detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

With the development of electronic technology, electronic devices such as smart phones are used more and more frequently in daily life of users. Among them, the audio playing function of the electronic device is one of the functions most used by users in the process of using the electronic device. For example, when a user uses an electronic device to enjoy movies, TV shows, 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 put forward higher requirements on the sound effect when the electronic device plays audio. For example, when using the audio output function of the electronic device, the electronic device may output a stereo output effect through the set speaker.

However, limited by the thinness and portability of electronic devices, the configuration of a single speaker has been difficult to meet the increasing needs of users for audio playback scenarios, such as loudness and surround feeling. In order to enhance and improve the loudspeaker effect of electronic devices, more and more electronic devices are equipped with two or more speakers to obtain better stereo effects. However, limited by the thin and light body of the electronic device, and the squeeze of the limited internal space of the electronic device by the multi-camera and large battery installed in the electronic device, it is difficult to integrate two completely symmetrical speakers on the electronic device to achieve good performance. stereo effect.

The current configuration of the main process is generally to install a speaker with a weaker performance above the electronic device to realize the receiver function of the handheld microphone, and to install a speaker with better performance below the electronic device to assist in stereo output. Based on the configuration of the speaker system of the current electronic equipment, in most loudspeaker scenarios, it is often necessary to reduce the best performance of the speaker with better performance to balance the stereo loudspeaker effect. When adjusting the volume keys of electronic equipment, the performance of the two speakers installed in the electronic equipment is often adjusted synchronously, and there is always an asymmetric sense of hearing of "weak at the top and strong at the bottom". poor. Among them, when the volume key of the electronic device is adjusted, the performance of the two speakers set in the electronic device is often adjusted synchronously, which means that the performance of the two speakers set in the electronic device increases or decreases simultaneously with the adjustment of the volume key; " The asymmetric sense of hearing of "weak at the top and strong at the bottom" is due to the fact that the performance of the speakers installed above the electronic equipment is weak, while the performance of the speakers installed below the electronic equipment is better.

Therefore, the inventor proposes a loudspeaker 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 is controlled to remain constant, while the volume output by the second speaker is controlled to change with the change of the volume level . Through the above method, when 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 is controlled to remain constant, and at the same time, the performance of the second speaker is fully improved, so that the first speaker and the The second speaker can output a balanced stereo effect, which improves the user experience.

The following introduces the application environment of the loudspeaker control method provided by the implementation of the present invention:

Referring to FIG. 1 , the speaker control method provided by the implementation of the present invention can be applied to the electronic device 100 shown in FIG. 1 , and the electronic device 100 can include two or more speakers. Exemplarily, as shown in FIG. 1 , the electronic device 100 may include two speakers, a first speaker 110 and a second speaker 120 . Wherein, the performances of the first speaker 110 and the second speaker 120 may be the same or different. Optionally, the performance of the first speaker 110 can be higher than the performance of the second speaker 120; the performance of the first speaker 110 can also be lower than the performance of the second speaker 120; the performance of the first speaker 110 can also be equal to the performance of the second speaker 120 performance. When the performance of the first speaker 110 is equal to that of the second speaker 120 , balanced stereo sound may be output through the first speaker 110 and the second speaker 120 . Therefore, when the performance of the first speaker 110 and the performance of the second speaker 120 are different, in order to output balanced stereo sound and give the user a good sound experience, the performance of the first speaker 110 or the second speaker 120 can be adjusted. , so that after adjustment, balanced stereo sound can be output through the first speaker 110 and the second speaker 120 .

In the embodiment of the present application, both the first speaker 110 and the second speaker 120 can have two binding posts (two leads), and when only the first speaker 110 or the second speaker 120 is used in the electronic device 100, the two pins Positive and negative polarities are not distinguished; when the first speaker 110 and the second speaker 120 in the electronic device 100 are used at the same time, the two pins have different polarities.

In the embodiment of the present application, as shown in FIG. 1 , in the electronic device 100, the first speaker 110 may be arranged at the upper end of the electronic device 100, the second speaker 120 may be arranged at the lower end of the electronic device 100, and the first speaker 110 and the second speaker 120 can be driven by a separate smart power amplifier (Smart PA). For example, the smart power amplifier 1 drives the first speaker 110 to run, and the smart power amplifier 2 drives the second speaker 120 to run.

Intelligent power amplifiers generally use a full-bridge inverter circuit. The full-bridge inverter circuit of the intelligent power amplifier can be seen in Fig. 2, including four switching tubes of Q1, Q2, Q3 and Q4, each switching tube is connected with a diode at the input end and the output end. The input terminals of the switching tube Q1 and the switching tube Q3 are connected to the DC voltage VBOOST, and the output terminals of the switching tube Q2 and the switching tube Q4 are grounded. The common terminal of the switch tubes Q1 and Q2 is used as the SPK-P terminal, the common terminal of the switch tubes Q3 and Q4 is used as the SPK-N terminal, and the SPK-P terminal and the SPK-N terminal are connected to the speaker.

The switching tubes Q1 to Q4 shown in FIG. 2 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. But the switch tubes Q1 to Q4 can also use other forms of switch tubes.

Optionally, in the intelligent power amplifier, the four switch tubes are turned on in time sharing to provide voltage for the speaker to operate. Specifically, as shown in FIG. 3 , in the first stage: the switching tubes Q1 and Q4 are turned on, the switching tubes Q2 and Q3 are turned off, and the DC voltage VBOOST supplies power to the speaker along the direction indicated by ①. The second stage: the switch tubes Q1 and Q4 are cut off, the switch tubes Q2 and Q3 are turned on, and the DC voltage VBOOST supplies power to the speaker along the direction indicated by ②.

It should be noted that, in addition to the smart phone shown in FIG. Personal computers (Ultra-mobile Personal Computer, UMPC), handheld computers, netbooks, personal digital assistants (Personal Digital Assistant, PDA), smart speakers and other devices can be configured with two or more speakers.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 4, a loudspeaker control method provided in an embodiment of the present application is applied to the electronic device shown in FIG. 1, and the method includes:

Step S110: 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, control the volume output by the first speaker to remain unchanged.

In this embodiment of the present application, the electronic device includes a first speaker and a second speaker. Wherein, the first speaker and the second speaker are asymmetrical speakers.

In this embodiment of the present application, the fact that the first speaker and the second speaker are asymmetrical speakers means that the best performances of the first speaker and the second speaker are different. Optionally, the first speaker is a speaker with a lower performance among the two speakers, and the second speaker is a speaker with a higher performance among the two speakers. That is to say, in this embodiment of the application, the best performance of the first speaker Below the best performance of the second speaker.

As a method, the loudspeaker is a key part of the sound system, and the sound reproduction quality of the loudspeaker is mainly determined by the performance index of the loudspeaker. In the embodiment of the present application, the performance of the loudspeaker may be characterized by the numerical value of the performance index of the loudspeaker. The performance index of the loudspeaker may include rated power, rated impedance, frequency characteristics, harmonic distortion, sensitivity, directivity, etc.

Among them, the rated power of the speaker refers to the output power that the speaker can work for a long time, also known as the undistorted power, which is generally marked on the nameplate at the rear of the speaker. When the speaker works at the rated power, the voice coil will not produce overheating or mechanical overload, and the sound will not show distortion. The rated power is an average power, but in fact the speaker 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 will exceed the rated power many times. Short enough not to damage speakers, but with the potential for distortion. Therefore, in order to ensure that the sound quality can still be obtained well when the peak pulse occurs, the speaker must retain sufficient power headroom. The maximum power that a general speaker can handle is 24 times the rated power.

The rated impedance of the speaker refers to the ratio of the voltage applied to the input terminal of the speaker to the current flowing through the speaker in the rated state. Now, the rated impedance of the speaker is generally 2, 4, 8, 16, 32 ohms and so on. The rated impedance of the loudspeaker is measured under the condition of inputting 400Hz signal voltage.

The frequency characteristic of the speaker is an index to measure the audio frequency bandwidth of the speaker. The high-fidelity playback system requires that the speaker system should be able to reproduce the audible range of 10Hz to 2000Hz. Since it is difficult to achieve this range with a single speaker, the current high-fidelity speaker system uses three types of speakers, high, medium, and low, to achieve full-band playback coverage. In addition, the frequency characteristics of the high-fidelity speaker should be as flat as possible, otherwise it will introduce frequency distortion of playback. The high-fidelity playback system requires that the unevenness of the frequency characteristics of the speaker in the playback frequency range is less than 10dB.

There are many kinds of speaker distortion, the common ones are harmonic distortion (mostly caused by the uneven magnetic field of the speaker and the distortion of the vibration system, often at low frequencies), intermodulation distortion (because two signals of different frequencies are added to the speaker at the same time, The sound quality of intermodulated audio is degraded) and instantaneous distortion (because the inertia of the vibration system cannot follow the change of the signal, thus causing signal distortion), etc. The harmonic distortion of the speaker refers to the addition of harmonic components that were not in the original signal during playback. The harmonic distortion of the speaker comes from the non-uniform magnetic field of the magnet, the characteristics of the diaphragm, and the nonlinear distortion such as the displacement of the voice coil. At present, the harmonic distortion index of better speakers is not more than 5%.

The sensitivity of the loudspeaker usually refers to the sound pressure measured at the front 1m of the axial direction of the loudspeaker when the input power is the noise voltage of 1W. Sensitivity is a measure of how well a speaker reproduces details in an audio signal. The more sensitive a speaker is, the better it responds to details in the audio signal. As a HiFi speaker, the sensitivity should be greater than 86dB/W.

The loudspeaker has different sound pressure frequency characteristics for radiation in different directions, and this characteristic becomes the directivity of the loudspeaker. It is related to the caliber of the speaker. When the caliber of the speaker is large, the directivity of the speaker is sharp, and when the caliber of the speaker is small, the directivity of the speaker is wide. The directivity of the speaker is also related to the frequency. Generally speaking, there is no obvious directivity for low-frequency signals below 250Hz; there is obvious directivity for high-frequency signals below 1.5kHz.

In the embodiment of the present application, the preset performance may be the best performance corresponding to the speaker with weaker performance among the two speakers. Wherein, the best performance may be the maximum value of any one of the above-mentioned performance indexes set in advance, or may be different values set for the above-mentioned different performance indexes after comprehensive evaluation of the above-mentioned performance indexes. For example, if the best performance of the first speaker is lower than the best performance of the second speaker, then the preset performance may be the best performance of the first speaker. Specifically, the maximum rated power of the first speaker may be set as the preset performance; or a value obtained by weighted summation of performance characteristics corresponding to the first speaker may be set as the preset performance, which is not specifically limited here.

Optionally, the preset performance may also be determined by modeling, match the performance balance point of the first speaker and the second speaker, and use the performance corresponding to the performance balance point as the preset performance. Specifically, when matching the best performance of the first speaker and adjusting the performance of the second speaker so that the performance is close, it is a determined preset performance.

Wherein, when determining the preset performance by modeling, since the best performance of the first speaker is lower than the best performance of the second speaker, the performance of the first speaker and the second speaker can be adjusted to their corresponding After the best performance of the first speaker, keep the best performance of the first speaker unchanged, and then gradually reduce the performance of the second speaker, find the performance balance point of the first speaker and the second speaker, and then determine the performance corresponding to the performance balance point as Default performance.

Furthermore, for most users, when using the audio output function of electronic equipment, in a relatively quiet environment, they are more concerned about the quality of the sound, that is, the effect of the speaker output is required to be balanced, and the sound is clear and comfortable; while in a noisy environment In the environment, the volume key is often adjusted to the maximum, and greater loudness is required to satisfy the user to obtain the sound content of the electronic device, and the demand for sound and sound quality will be reduced. In order to improve the asymmetric stereo effect and enhance the loudspeaker effect of electronic equipment, two smart power amplifiers can be used to drive the first speaker and the second speaker respectively, and set separate volume curves for the first speaker and the second speaker Configuration, so that when the user adjusts the volume key, the first speaker and the second speaker switch from the original synchronous change to an independent change, so that the first speaker and the second speaker independently reduce or maintain the output effect with the change of the volume key, thereby Asymmetric speakers can also output balanced stereo effects in most scenarios. That is to say, when it is detected that the user adjusts the volume key, according to the adjustment of the volume key, through the corresponding volume curve configurations of the two speakers, the volume output by the first speaker is adjusted to correspond to the corresponding volume level in the corresponding volume curve. the volume of the second loudspeaker; adjust the volume output by the second speaker to the volume corresponding to the corresponding volume level in the corresponding volume curve.

In the embodiment of the present application, volume curve configurations corresponding to the first speaker and the second speaker are different. Among them, the volume curve is used to represent the linear relationship between the volume level and the volume. The volume level corresponds to the adjustment of the volume key, and each level in the volume level corresponds to one adjustment of the volume key. That is to say, the volume key is adjusted once, and the volume level is changed once.

Exemplarily, as shown in FIG. 5 , FIG. 5 is a volume curve separately set for the first speaker and the second speaker. Wherein, the upper speaker in FIG. 5 is the first speaker in the embodiment of the present application, and the lower speaker in FIG. 5 is the second speaker in the embodiment of the present application. It can be seen from the data in FIG. 5 that the volume curves corresponding to the first speaker and the second speaker are different, and the volume levels corresponding to the same volume level are different. It can also be known from the data in Figure 5 that when the volume level is 12, the performance of the first speaker reaches the best performance, which is close to the performance of the second speaker, so the volume level 12 can be determined as the performance balance point, and the The performance corresponding to the performance balance point is determined as the preset performance.

As a manner, when it is detected that the performance of the second speaker is higher than the preset performance and the performance of the first speaker is at the highest performance, if a change in the volume level is detected, the volume output by the first speaker remains unchanged. That is to say, if it is detected that the performances of the first speaker and the second speaker are both above the performance corresponding to the performance balance point, then the performance of the first speaker is controlled to remain unchanged. Whether an increase or a decrease in the volume level is detected, the performance of the first speaker remains the same.

Step S120: Simultaneously controlling the volume output by the second speaker to vary with the volume level.

In the embodiment of the present application, when a change in the volume level is detected, the volume output by the second speaker is controlled to change according to the change in the volume level. Specifically, if it is detected that the volume level increases, the volume output by the second speaker is controlled to increase; if it is detected that the volume level decreases, the volume output by the second speaker is controlled to decrease. Through the above method, the balanced output of the first speaker and the second speaker can be guaranteed as much as possible, and at the same time, the performance of the second speaker can be fully utilized at high volume to improve the overall loudness to meet user needs.

A speaker control method provided by 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 is controlled to remain unchanged, and the output of the second speaker is controlled at the same time The volume of the volume changes with the change of the volume level. Through the above method, when 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 is controlled to remain constant, and at the same time, the performance of the second speaker is fully improved, so that the first speaker and the The second speaker can output a balanced stereo effect, which improves the user experience.

Please refer to FIG. 6, a loudspeaker control method provided by an embodiment of the present application is applied to the electronic device shown in FIG. 1, and the method includes:

Step S210: In the case that the performance of the second speaker is lower than the preset performance, in response to the change of the volume level, control the volume output by the first speaker and the volume output by the second speaker It changes synchronously with the change of the volume level.

In the embodiment of the present application, if it is detected that the performance of the second speaker is lower than the preset performance, and the performance of the first speaker is also lower than the preset performance, the first speaker and the second speaker are controlled in response to the change of the volume level. The output volume of the two speakers changes synchronously with the change of the volume level.

As a manner, controlling the volume output by the first speaker and the volume output by the second speaker to change synchronously with the change of the volume level includes: controlling the volume output by the first speaker and the volume output by the second speaker The volume output by the two loudspeakers is simultaneously attenuated by the same magnitude as the volume level decreases; or, the volume output by the first speaker and the volume output by the second speaker are controlled to increase simultaneously with the increase in the volume level same magnitude.

That is to say, in the above case, if it is detected that the volume level decreases, the volume output by the first speaker and the second speaker will be reduced at the same time; if the volume level is detected to increase, the output volume of the first speaker and the second speaker will be increased volume.

In the speaker control method provided by the present application, when the performance of the second speaker is lower than the preset performance, in response to the change of the volume level, the volume output by the first speaker and the volume output by the second speaker are controlled with the volume level. The change of the number changes synchronously. Through the above method, when the performance of the second speaker is lower than the best performance of the first speaker, the volumes output by the first speaker and the second speaker are controlled to change synchronously, so that the first speaker and the second speaker can output balanced Stereo effect to enhance user experience.

Please refer to FIG. 7, a loudspeaker control method provided by an embodiment of the present application is applied to the electronic device shown in FIG. 1, and the method includes:

Step S310: Obtain the best performance of the first speaker.

Step S320: Use the best performance as the preset performance.

In the embodiment of the present application, the best performance of the first speaker may be directly used as the preset performance.

Step S330: When the performance of the second speaker is higher than the preset performance, in response to the change of the volume level, drive the first speaker to work through the first power amplifier, so as to control the first speaker The volume of the output remains unchanged.

In the embodiment of the present application, in order to improve the external playback effect of the electronic device. Different speakers can be driven by two power amplifiers. Specifically, as shown in FIG. 8 , FIG. 8 is a schematic diagram of a driving circuit in an embodiment of the present application. In the embodiment of the present application, the driving circuit may be a Microcontroller Unit (MCU), a first power amplifier (PA1), a second power amplifier (PA2), a first speaker (SPK1) and a second speaker (SPK2). Wherein, the micro control unit can respectively select addresses for the first power amplifier (PA1) and the second power amplifier (PA2) through the I2C bus. At the same time, the micro control unit can connect the first power amplifier (PA1), the second power amplifier (PA2), the first speaker (SPK1) and the second speaker (SPK2) through the integrated circuit built-in audio bus (Inter-IC Sound, I2S) . Wherein, when connected, as shown in Figure 9, the micro control 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) ; The micro control unit, the second power amplifier (PA2) and the second speaker (SPK2) form a path to pass through the second power amplifier (PA2) and the second speaker (SPK2).

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

As a method, when the first speaker is driven by the first power amplifier to control the output volume of the first speaker to remain constant, the first power amplifier can be controlled to drive the first speaker to work with a constant power, thereby controlling the first speaker The volume of the output remains unchanged.

Step S340: Simultaneously drive the second speaker to work through the second power amplifier, so as to control the output volume of the second speaker to change with the change of the volume level.

In the embodiment of the present application, when the second speaker is driven by the second power amplifier to control the output volume of the second speaker to change with the volume level, the second power amplifier can be controlled to drive the second speaker with different power. The loudspeaker works so as to control the second loudspeaker to output volumes of different sizes under different powers.

In a speaker control method provided by the present application, the best performance of the first speaker is obtained first, and the best performance is set as the preset performance, and then when the performance of the second speaker is higher than the preset performance, responding to the volume level The number changes, the first speaker is driven by the first power amplifier to control the output volume of the first speaker to remain constant, and the second speaker is driven by the second power amplifier to control the output volume of the second speaker with the volume level. changes with the number. Through the above method, different speakers are driven by different power amplifiers, which can ensure sufficient driving capability when using the external speaker function of the electronic device, and ensure optimal system sound effects. Furthermore, when 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 is controlled to remain constant, and at the same time, the performance of the second speaker is fully improved, so that the first speaker and the second speaker The two speakers can output a balanced stereo effect, which improves the user experience.

Please refer to FIG. 9, a loudspeaker control method provided in an embodiment of the present application is applied to the electronic device shown in FIG. 1, and the method includes:

Step S410: Obtain the current playback scene.

In the embodiment of this application, in different playback scenarios, users have different requirements for stereo effects, so different audio parameters can be set in advance for different playback scenarios to meet the needs of users in different playback scenarios. Different needs for effects.

As a manner, the external playback scene may include a music listening scene, a video watching scene, a phone call scene, etc., which are not specifically limited here. Each playing scene can usually be associated with a certain application program in the electronic device, therefore, the current playing scene can be determined by detecting the running application program in the electronic device. For example, watching a video scene may be associated with a video playing application in the electronic device, therefore, it may be determined whether the current video playing scene is by detecting whether the video playing application in the electronic device is running.

Optionally, it is also possible to set different scene identifiers for different playback scenarios, and then determine which one is the current playback scenario by determining whether the corresponding application identifier is detected.

Of course, the manner of determining the current playback scene may be performed when it is detected that the electronic device is in the playback mode.

In the embodiment of the present application, a target control may be set in the electronic device to control whether the electronic device switches to the external playback mode. When it is detected that the target control is in the first state, it is determined that the electronic device is in the external release mode; when it is detected that the target control is in the second state, it is determined that the electronic device is not in the external release mode. Wherein, the first state indicates that the target control is in the running state, and the second state indicates that the target control is in the idle state.

Step S420: Obtain audio parameters corresponding to the playback scene.

In the embodiment of the present application, the audio parameters may include the number of channels, quantization bits, sampling frequency, bit rate, and so on. In different playback scenarios, the values of the above audio parameters may be set differently.

As a manner, the corresponding relationship between the playback scene and the audio parameter can be established in advance, and then after the current playback scene is determined, the corresponding audio parameter can be determined through the corresponding relationship.

Step S430: 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, based on the audio parameter, drive the first speaker to the The audio parameter works to control the output volume of the first speaker to remain constant.
