[0002] With the development of electronic technology, various electronic devices have been created to meet the different needs of users. Among them, speakers as audio playback devices are one of them. Audio playback devices are widely used in home audio and video, shopping mall promotions, conference speeches and other scenarios. Audio playback devices usually need to use a power adapter to provide appropriate power supply, so as to convert the AC power of the mains into DC power suitable for the operation of audio playback devices. In addition, in order to adapt to various power adapters already used in the market, audio playback devices are designed to match and use various models and specifications of power adapters circulating in the market.

[0056] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] It should be noted that the power adapters currently circulating on the market usually support one or more charging protocols, such as USB PD (USB Power Delivery) charging protocol, Quick Charge (QC) fast charging technology, etc. The power that power adapters that support different charging protocols can provide to audio playback devices is different, and in order to facilitate circulation and improve adaptability, audio playback devices are often configured to be compatible with power adapters with different charging protocols. In view of this, in the prior art, audio playback devices only perform function display and audio playback modes according to their own output power requirements, which may not match the power supply that the power adapter can provide. For example, when the power adapter supplies power to an audio playback device that requires more power, it may cause the power adapter to operate dangerously at overpower, or directly cause the corresponding function of the audio playback device to fail to achieve the preset effect due to insufficient power.

[0058] Based on the above understanding, this application uses software algorithms to manage and control the functions of audio playback devices, without requiring too much adjustment to the hardware design, which is conducive to the miniaturization and lightweight of the product and also to product cost control. Figure 1 The present application is applied to an adaptive power control method for an audio playback device, comprising:

[0059] 101. Determine a current voltage value output by a power adapter of an audio playback device.

[0060] Specifically, this step can read the charging protocol of the power adapter of the audio playback device, and then determine the current voltage value output by the power adapter of the audio playback device from the charging protocol. Take the example that the audio playback device and the power adapter are connected via a Type-C interface data cable, and the power adapter supports the USB PD protocol. In this embodiment, the main controller of the audio playback device can directly read the USB PD protocol currently executed by the power adapter through the Type-C interface data cable, and then know the current voltage value output by the power adapter from the USB PD protocol currently executed by the power adapter. The main controller of this embodiment can be MT6750 of MediaTek MTK.

[0061] 102. Determine a current optimal output power of the audio playback device according to a current voltage value and a rated current value corresponding to a current volume level of the audio playback device.

[0062] It is understandable that the audio playback device needs to achieve different playback volumes at different volume levels, and the different playback volumes in the audio playback device correspond to different current values ​​flowing into the playback speakers. Then, when the power adapter provides a certain current voltage value to the playback speaker of the audio playback device, the rated current value required to achieve the best audio playback effect is different for the current audio level of the audio playback device. If the corresponding power adapter cannot provide a large enough current (that is, the actual current value is less than the rated current value of the current audio level), the audio playback device cannot reach the current optimal output power corresponding to the current volume level, and cannot achieve the best audio playback effect of the current audio level. The current optimal output power is equal to the current voltage value multiplied by the rated current value.

[0063] 103. Determine whether the current optimal output power is greater than the maximum power supply that the power adapter of the audio playback device can provide. If the current optimal output power is greater than the maximum power supply that the power adapter of the audio playback device can provide, execute step 104; if the current optimal output power is less than or equal to the power supply that the power adapter of the audio playback device can provide, execute step 105.

[0064] In this embodiment, whether the current optimal output power is greater than the maximum power supply power that the power adapter of the audio playback device can provide is used as a judgment standard. If the current optimal output power is greater than the maximum power supply power that the power adapter of the audio playback device can provide, it indicates that the power adapter is unable to provide a sufficiently large current for the current volume level of the audio playback device to drive the speaker to play the best audio effect; if the current optimal output power is less than or equal to the power supply power that the power adapter of the audio playback device can provide, it indicates that the power adapter is capable of providing a sufficient current for the current volume level of the audio playback device to drive the speaker to play the best audio effect.

[0065] 104 . Lower the current volume level of the audio playback device by one level, triggering execution of step 101 .

[0066] When it is determined in step 103 that the current optimal output power of the audio playback device is greater than the maximum power supply that the power adapter of the audio playback device can provide, it indicates that the power adapter is unable to provide a sufficiently large current for the current volume level of the audio playback device to drive the speaker to play the best audio effect. In order to avoid the possibility of over-power operation of the power adapter and ensure that the audio playback device does not continue to play audio at the current volume level that cannot achieve the best audio playback effect, this step adjusts the current volume level of the audio playback device down by one level, and triggers the execution of step 101, thereby achieving step-by-step matching and adjustment of the adaptive power of different power adapters when the audio playback device outputs the current optimal output power until the current optimal output power output of the audio playback device at the corresponding volume level matches the power that the power adapter can provide, ensuring that the audio playback device does not stay and play for too long at a volume level that does not meet the power playback requirement, and ensuring that the power adapter is not used for too long under an over-power overload condition, thereby ensuring the safety of the audio playback device and the power adapter.

[0067] 105. Ignore.

[0068] When it is determined in step 103 that the current optimal output power is less than or equal to the power supply that the power adapter of the audio playback device can provide, it indicates that the power adapter is capable of providing sufficient current for the current volume level of the audio playback device to drive the speaker to play the best audio effect. This step does not intervene in the volume level of the audio playback device.

[0069] See also Figure 2 Another embodiment of the adaptive power control method of the present application applied to an audio playback device includes:

[0070] 201. When the audio playback device is in an audio playback state, read a charging protocol of a power adapter of the audio playback device.

[0071] Specifically, the audio playback device in this embodiment may often be powered by different power adapters, or the power adapter powers multiple devices at the same time, and the power that the power adapter can provide to the audio playback device may be dynamically changing. Then the audio playback device in this embodiment needs to periodically execute the adaptive power control method of the embodiment of the present application to achieve dynamic adaptive power control. In this step, when the audio playback device is in the audio playback state, the charging protocol of the power adapter of the audio playback device is read to save the computing power expenditure of the audio playback device. Specifically, taking the audio playback device and the power adapter connected through the Type-C interface data cable, and the power adapter supporting the USB PD protocol as an example, the main controller of the audio playback device in this embodiment can directly read the USB PD protocol currently executed by the power adapter through the Type-C interface data cable. The main controller of this embodiment can be MT6750 of MediaTek MTK Co., Ltd.

[0072] 202. Determine a current voltage value output by a power adapter of the audio playback device from the charging protocol.

[0073] Specifically, the USB PD protocol currently executed by the power adapter is read in step 201 to obtain the current output voltage value thereof.

[0074] 203. Determine a current optimal output power of the audio playback device according to the current voltage value and the rated current value corresponding to the current volume level of the audio playback device, where the current optimal output power is equal to the current voltage value multiplied by the rated current value.

[0075] This step is performed in the same way as above. Figure 1 The operations performed in step 102 of the embodiment are similar, and the repeated parts are not repeated here.

[0076] It should be noted that the audio playback device pre-stores rated current values ​​corresponding to different supply voltage values ​​when different volume levels are required to achieve the best playback effect. The above-mentioned current voltage value in this embodiment is one of the supply voltage values.

[0077] 204. Calculate the maximum power supply of the power adapter of the audio playback device.

[0078] Specifically, the maximum power supply that can be currently provided by the power adapter of the audio playback device is equal to the current voltage value multiplied by the maximum current value allowed to be output at the current voltage value specified by the charging protocol.

[0079] 205. Determine whether the current optimal output power is greater than the maximum power supply that the power adapter of the audio playback device can provide. If the current optimal output power is greater than the maximum power supply that the power adapter of the audio playback device can provide, execute step 206; if the current optimal output power is less than or equal to the power supply that the power adapter of the audio playback device can provide, execute step 209.

[0080] This step is performed in the same way as above. Figure 1 The operations performed in step 103 of the embodiment are similar, and the repeated parts are not repeated here.

[0081] 206. Determine whether there are any non-essential functions that can be turned off. If there are any non-essential functions that can be turned off, execute step 207; if there are no non-essential functions that can be turned off, execute step 208.

[0082] If it is determined in step 205 that the current optimal output power is greater than the maximum power supply that the power adapter of the audio playback device can provide, then under the premise of maintaining the current volume level of the audio playback device, this step can also try to turn off the non-essential functions of the audio playback device first, so as to save the power of some functions and transfer it to the current optimal output power required for the audio playback corresponding to the current volume level of the audio playback device. To this end, this step first determines whether there are non-essential functions that can be turned off. If there are non-essential functions that can be turned off, it indicates that there is some functional power that can be saved to be transferred to the current optimal output power required for the speaker to play audio corresponding to the current volume level of the audio playback device; if there are no non-essential functions that can be turned off, it indicates that there is no part of the functional power that can be saved to be transferred to the current optimal output power required for the speaker to play audio corresponding to the current volume level of the audio playback device. The so-called non-essential functions include: one or more of the atmosphere light function, the hotspot function, and the screen display function.

[0083] 207 . Disable non-essential functions, triggering execution of step 101 .

[0084] When it is determined in step 206 that the audio playback device has non-essential functions that can be turned off, it indicates that some functional power can be saved and used to transfer the current optimal output power required for the speaker corresponding to the current volume level of the audio playback device to play audio, so as to provide partial power support for the speaker corresponding to the current volume level to play the current optimal playback effect.

[0085] 208 . Lower the current volume level of the audio playback device by one level, triggering execution of step 101 .

[0086] When it is determined in step 206 that the audio playback device has no unnecessary functions to be turned off, it means that there is no partial functional power that can be saved to transfer to the current optimal output power required for the speaker corresponding to the current volume level of the audio playback device to play audio. This step can only adjust the current volume level of the audio playback device down by one level.

[0087] 209. Ignore, triggering execution of step 101.

[0088] This step is performed in the same way as above. Figure 1 Step 105 in the embodiment is similar, and the repeated parts are not repeated here.
