[0018] In order to better understand the technical solution of the present invention, the following detailed description of embodiments of the present invention will be given with reference to the accompanying drawings.

[0019] It is clear that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments, and all other embodiments that a person skilled in the art can obtain based on the embodiments of the present invention without any creative work are all included in the protection scope of the present invention.

As used in the embodiments of the present invention and the appended claims, the singular forms "a," "the," and "said" are also intended to include the plural forms unless the context clearly dictates otherwise.

Note that the symbol " / " here generally means that the related objects before and after are in an "or" relationship.

[0022] An embodiment of the present invention provides a method for controlling power consumption of a speaker, where FIG. 1 is a flowchart of the method for controlling power consumption of a speaker according to an embodiment of the present invention, FIG. 2 is a schematic diagram of the method for controlling power consumption of a speaker according to an embodiment of the present invention, and FIG. 3 is a schematic diagram of another method for controlling power consumption of a speaker according to an embodiment of the present invention, and as shown in FIG. 1, FIG. 2 or FIG. 3, the method includes the following contents:

[0023] In step 102, environmental state information is acquired by an environmental information collection device.

[0024] In an embodiment of the present invention, each step is performed by an electronic device, for example, the electronic device includes a mobile phone, a tablet computer, a computer, or a wearable device.

[0025] In an embodiment of the present invention, the method further includes, before step 102, obtaining an audio stream, and performing normal audio processing on the audio stream to generate a processed audio stream.

[0026] In an embodiment of the present invention, the environmental information collecting device includes a microphone, a light sensor, or a temperature sensor.

[0027] In an embodiment of the present invention, the environmental state information includes environmental sound information, environmental light brightness information, or environmental temperature information.

[0028] For example, environmental sound information is acquired by a microphone, environmental light luminance information is acquired by a light sensor, and environmental temperature information is acquired by a temperature sensor.

[0029] In step 104, the environmental condition analysis module analyzes the environmental condition information to generate an environmental condition result.

[0030] In an embodiment of the present invention, the environmental condition result includes a low-frequency noise level of the environment, for example, the environmental condition analysis module generates the low-frequency noise level of the environment by analyzing the environmental audio information.

[0031] In step 106, a mode selection input from the user is received.

[0032] In this step, the user inputs a mode selection result, for example, the mode selection result includes a performance mode, a balanced mode, or a power saving mode.

[0033] In step 108, the power consumption parameter calculation module generates power consumption control parameters based on the environmental condition results and the mode selection results.

[0034] Specifically, the power consumption parameter calculation module generates the power consumption control parameters based on the preset speaker parameters, the environmental condition result, and the mode selection result.

[0035] As an alternative solution, the mode selection results selected by the user are combined based on an audio masking effect model to generate power consumption control parameters corresponding to the mode selection results.

[0036] In an embodiment of the present invention, the power consumption control parameters include a high-pass filter cutoff frequency parameter, which is adjustable, and the specific high-pass filter cutoff frequency parameter is set by the power consumption control parameter calculation module.

[0037] For example, if the cutoff frequency of the high-pass filter is set to 600Hz in the power-saving mode, the speaker will only output signals above 600Hz. Because the low-frequency band of a microspeaker accounts for a large proportion of its power consumption, this operation will significantly reduce the power consumption of the microspeaker, typically by 50%, thereby achieving the purpose of power saving.

[0038] In step 110, the power consumption reduction module performs power consumption control on the speaker based on the power consumption control parameters.

[0039] In an embodiment of the present invention, the power saving module includes a high-pass filter.

[0040] In an embodiment of the present invention, the power consumption reduction module performs power consumption control on the processed audio stream based on the power consumption control parameters, so that the speaker performs power amplification based on the power consumption control parameters, thereby reducing the power consumption of the speaker.

[0041] In the embodiment of the present invention, it is widely known that low-frequency noise is strong in a noisy environment. For example, the noise reduced by a noise-reduction earphone is mainly low-frequency noise. FIG. 4 is a schematic diagram of a typical frequency response curve of a microspeaker, and FIG. 5 is a schematic diagram of the sound masking effect. As shown in FIG. 4, it is also well known that the low-frequency response of a microspeaker used in an electronic device is relatively weak. That is, the low-frequency response is insufficient before the microspeaker's f0 (resonance frequency), and the lower the frequency, the lower the sound pressure level. For a microspeaker, a typical value of the microspeaker's f0 may be around 800 Hz. As shown in FIG. 5, due to the existence of the "masking effect," it can be seen that when the low-frequency loudness of external sound is high, it can easily mask the low-loudness low-frequency sound emitted from the microspeaker of an electronic device.

[0042] In an embodiment of the present invention, Figure 6 is a schematic diagram of a low-frequency noise spectrum in environmental noise. As shown in Figure 6, when listening to music using loud mode in a noisy environment with a large amount of low-frequency noise, the low-frequency components reproduced by the speaker can be weakened. In this way, not only is the usage experience in these environmental scenes not affected (because the low-frequency sound emitted from the speaker cannot be effectively heard in these scenes), but wasteful power consumption can also be significantly reduced. The low-frequency noise spectrum in the environmental noise of Figure 6 may be the environmental condition result generated in step 104.

[0043] In the embodiment of the present invention, FIG. 7 is a schematic diagram illustrating the application of the method for controlling power consumption of a speaker according to the embodiment of the present invention. By comparing the low-frequency noise spectrum of the environmental noise in FIG. 6 with the typical frequency response curve of a micro-speaker in FIG. 4, it can be easily seen that the low-frequency output of the micro-speaker is easily masked by the low-frequency components of the environmental noise, making it difficult to hear the low-frequency sound emitted from the micro-speaker.

[0044] In a technical solution according to an embodiment of the present invention, an environmental information collecting device acquires environmental state information, an environmental state analysis module analyzes the environmental state information to generate an environmental state result, a mode selection result input by a user is received, a power consumption parameter calculation module generates power consumption control parameters based on the environmental state result and the mode selection result, and a power consumption reduction module controls power consumption of the speaker based on the power consumption control parameters. In the technical solution according to an embodiment of the present invention, by generating power consumption control parameters based on the environmental state result and the mode selection result by the power consumption parameter calculation module and controlling power consumption of the speaker based on the power consumption control parameters by the power consumption reduction module, the power consumption of the speaker can be dynamically controlled and power consumption can be further reduced.
