Description

Technical Field

[0001] This application belongs to the field of power control technology, and in particular relates to an adaptive power control method and related apparatus. Background Technology

[0002] With the development of electronic technology, various electronic devices have been created to meet different user needs. Among them, speakers, as audio playback devices, are widely used in home theaters, shopping mall promotions, conference presentations, and other scenarios. Audio playback devices typically require a power adapter to provide suitable power, converting AC mains power into DC power suitable for the device's operation. Furthermore, to be compatible with various power adapters available on the market, audio playback devices are designed to be compatible with a wide range of power adapter models and specifications.

[0003] However, existing power adapters on the market come in various models and specifications, such as 5V / 1A, 5V / 2A, 9V / 2A, and 12V / 1A. The numbers and letters in these models indicate that the power adapter can convert AC mains power (e.g., 220V / 50HZ AC) into the corresponding DC voltage value and the maximum allowable output current value. This means that the power output of these power adapters is limited. When the power adapter supplies power to audio playback devices that require higher power, it may cause the power adapter to operate dangerously beyond its power limit, or directly cause the corresponding functions of the audio playback device to fail to achieve the preset effect due to insufficient power.

[0049] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0050] This application applies to an adaptive power control method for audio playback devices. First, the current voltage value output by the power adapter of the audio playback device is determined. Then, based on the current voltage value and the rated current value corresponding to the current volume level of the audio playback device, the current optimal output power of the audio playback device is determined, where the current optimal output power equals the current voltage value multiplied by the rated current value. Next, it is determined 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, the current volume level of the audio playback device is lowered by one level, and then the process of determining the current output power of the audio playback device's power adapter is triggered. The process involves determining the current voltage value, thereby enabling the audio playback device to adaptively adjust the power of different power adapters step by step when outputting its current optimal output power. This continues until the optimal output power of the audio playback device at the corresponding volume level matches the power that the power adapter can provide. This ensures that the audio playback device does not play at a volume level that is below the required power for extended periods, and that the power adapter is not used for excessively long periods under overload conditions, thus ensuring the safety of both the audio playback device and the power adapter. If the current optimal output power is less than or equal to the power supply that the audio playback device's power adapter can provide, this can be ignored, indicating that the audio playback device and the power adapter are safe to use at this time.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] It should be noted that power adapters currently on the market typically support one or more charging protocols, such as USB PD (USB Power Delivery) and Quick Charge (QC) fast charging technology. Power adapters supporting different charging protocols can provide varying amounts of power to audio playback devices. To facilitate distribution and improve compatibility, audio playback devices are often designed to be compatible with power adapters using different charging protocols. Therefore, in existing technologies, audio playback devices may only operate according to their own output power requirements, which could lead to a mismatch between the power supply and the power required by the power adapter. For example, if a power adapter supplies power to an audio playback device that requires more power, it may cause the power adapter to operate dangerously beyond its power limit, or it may directly cause the audio playback device's functions to fail to achieve their intended effects 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, requiring minimal adjustments to the hardware design. This facilitates product miniaturization and weight reduction, and also helps control product costs. Please refer to [link / reference]. Figure 1 This application relates to an adaptive power control method for audio playback devices, comprising:

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

[0060] Specifically, this step involves reading the charging protocol of the audio playback device's power adapter and then determining the current output voltage value of the power adapter from the charging protocol. Taking the audio playback device and power adapter connected via a Type-C interface data cable, with the power adapter supporting the USB PD protocol as an example, in this embodiment, the main controller of the audio playback device can directly read the USB PD protocol currently being executed by the power adapter via the Type-C interface data cable, and then determine its current output voltage value from the USB PD protocol currently being executed by the power adapter. In this embodiment, the main controller can be the MediaTek MT6750.

[0061] 102. Based on the current voltage value and the rated current value corresponding to the current volume level of the audio playback device, determine the current optimal output power of the audio playback device.

[0062] It's understandable that audio playback devices need to achieve different playback volumes at different volume levels. These different volume levels correspond to different current flows to the speakers. Given a fixed voltage supplied by the power adapter to the speakers, the rated current required to achieve optimal audio playback varies depending on the current audio level. If the power adapter cannot provide a sufficiently large current (i.e., the actual current is less than the rated current for the current audio level), the audio playback device cannot reach its optimal output power for that volume level, thus failing to deliver the best audio playback performance. The optimal output power equals the current voltage multiplied by the rated current.

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

[0064] In this embodiment, the criterion is whether the current optimal output power is greater than the maximum power that the power adapter of the audio playback device can provide. If the current optimal output power is greater than the maximum power that the power adapter of the audio playback device can provide, it indicates that the power adapter is not capable of providing enough current to drive the speaker to play the best audio effect at the current volume level of the audio playback device. If the current optimal output power is less than or equal to the power that the power adapter of the audio playback device can provide, it indicates that the power adapter is capable of providing enough current to drive the speaker to play the best audio effect at the current volume level of the audio playback device.

[0065] 104. Adjust the current volume level of the audio playback device to a lower level, triggering the execution of step 101.

[0066] If step 103 determines 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 sufficient current to drive the speaker to play the best audio effect at the current volume level of the audio playback device. In order to avoid the power adapter from operating at overpower and to ensure that the audio playback device does not continue to play audio at the current volume level where it 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. This enables the audio playback device to adaptively match and adjust the power of different power adapters step by step when outputting the current optimal output power, until the current optimal output power of the corresponding volume level of the audio playback device matches the power that the power adapter can provide. This ensures that the audio playback device does not stay at the volume level where it cannot reach the power playback requirement for too long, and also ensures that the power adapter is not used for too long under overpower overload conditions, thus ensuring the safety of the audio playback device and the power adapter.

[0067] 105. Ignore.

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

[0069] Please see Figure 2 Another embodiment of the adaptive power control method for audio playback devices applied in this application includes:

[0070] 201. When the audio playback device is in audio playback mode, read the charging protocol of the audio playback device's power adapter.

[0071] Specifically, the audio playback device in this embodiment may frequently be powered by different power adapters, or the power adapter may simultaneously power multiple devices. Therefore, the power supply that the power adapter can provide to the audio playback device may dynamically change. Thus, the audio playback device in this embodiment needs to periodically execute the adaptive power control method of this application embodiment to achieve dynamic adaptive power control. This step only reads the charging protocol of the audio playback device's power adapter when the audio playback device is in audio playback mode, in order to save the computing power expenditure of the audio playback device. Specifically, taking the audio playback device and the power adapter connected via a Type-C interface data cable, with 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 being executed by the power adapter via the Type-C interface data cable. The main controller in this embodiment can be the MT6750 from MediaTek Inc.

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

[0073] Specifically, the current output voltage value is determined by reading the USB PD protocol currently being executed by the power adapter in step 201.

[0074] 203. Based on the current voltage value and the rated current value corresponding to the current volume level of the audio playback device, determine the current optimal output power of the audio playback device. The current optimal output power is equal to the current voltage value multiplied by the rated current value.

[0075] The execution of this step is the same as described above. Figure 1 The operations performed in step 102 of the embodiment are similar, and the repeated parts will not be described again here.

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

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

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

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

[0080] The execution of this step is the same as described above. Figure 1 The operations performed in step 103 of the embodiment are similar, and the repeated parts will not be described again here.

[0081] 206. Determine if there are any unnecessary functions that can be turned off. If there are any unnecessary functions that can be turned off, proceed to step 207; if there are no unnecessary functions that can be turned off, proceed to step 208.

[0082] If step 205 determines that the current optimal output power is greater than the maximum power supplied by the audio playback device's power adapter, then, while maintaining the current volume level of the audio playback device, this step can also attempt to disable unnecessary functions of the audio playback device. This would save some of the power required by these functions to be transferred to the current optimal output power needed for audio playback at the current volume level. To do this, this step first determines if there are any unnecessary functions that can be disabled. If so, it indicates that some of the power saved can be transferred to the current optimal output power needed for audio playback at the current volume level of the audio playback device. If no unnecessary functions can be disabled, it indicates that no such power can be saved to transfer to the current optimal output power needed for audio playback at the current volume level of the audio playback device. Unnecessary functions include one or more of the following: ambient lighting function, hotspot function, and screen display function.

[0083] 207. Disable unnecessary functions and trigger step 101.

[0084] If it is determined in step 206 that there are unnecessary functions of the audio playback device that can be turned off, it means that there is a portion of the functional power that can be saved. This power can be transferred to 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 some power support for the speaker corresponding to the current volume level to play the current optimal playback effect.

[0085] 208. Adjust the current volume level of the audio playback device to a lower level, triggering the execution of step 101.

[0086] If step 206 determines that there are no unnecessary functions that can be turned off on the audio playback device, it means that there is no functional power that can be saved to be used as 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 to be lowered by one level.

[0087] 209. Ignore and trigger step 101.

[0088] The execution of this step is the same as described above. Figure 1 Step 105 in the embodiment is similar, and the repeated parts will not be described again here.
