Problems solved by technology

However, since the power consumption of Wi-Fi communication is much higher than that of Bluetooth, it limits the application of Wi-Fi communication in wireless earphones
In addition, in order to save the power consumption of Wi-Fi communication, the 802.11 standard protocol mentions whether to turn off the Wi-Fi communication mechanism to enter the power saving / sleep mode according to the current amount of data. However, these traditional Wi-Fi power saving mechanisms Since only the amount of data determines whether to enter the power saving / sleep mode, and the start and end time of data transmission cannot be predicted, the actual power saving effect is not good, and the throughput rate may be affected

Embodiment Construction

[0013] figure 1 A schematic diagram of a data transmission system 100 in accordance with an embodiment of the present invention. like figure 1 As shown, the data transmission system 100 includes two electronic devices (indicated by the main device 110 and the audio playback device 120 in this embodiment, and the main device 110 and the audio playback device 120 can directly wirelessly communicate with each other. However, wireless communication is performed by an access point (Access Point, AP) 130. The main device 110 includes a control circuit 112, a Wi-Fi module 114, and a timer 118, wherein the control circuit 112 can include a related circuit for processing audio data and controlling Wi-Fi module 114, which can be hardware. The circuit or the application executed by the processor; the audio playback device 120 includes a control circuit 122, a Wi-Fi module 124, a playing element 126, and a timer 128, wherein the control circuit 122 can include to handle audio data. And trans...

Abstract

The present invention relates to a method for controlling an audio playback device and a related control circuit. The invention discloses a method for controlling an audio playback device, which comprises the following steps: controlling an electronic device to use a first wireless communication module to perform wireless communication with the audio playback device; controlling the electronic device to use a burst The mode of transmission is to use only a part of the time in a time range to transmit an audio data to the audio playback device; control the audio playback device to continuously play the audio data within the time range; and when the audio playback device completes After the audio data is received, a second wireless communication module of the audio playback device is controlled to enter a sleep mode.

Description

Technical field [0001] The present invention relates to wireless communication, particularly a method of controlling an electronic device into a sleep mode by wireless communication. Background technique [0002] Most of the current wireless headphones are Bluetooth to transmit audio data, while the Bluetooth headset only requires less current when receiving audio data and sound playback, therefore, it can increase the use time of the battery in the Bluetooth headset. However, the biggest problem in Bluetooth transmission is that the throughput is too low, so the Bluetooth headset is not available for transmission of high quality without distortion. [0003] On the other hand, since wireless fidelity, Wi-Fi communication can reach a high throughput rate, such as 802.11g, the highest can be 54 million yuan / sec (Mbps), so it is very suitable for transmission high quality Distortion music. However, since the power consumption of Wi-Fi communication is far higher than Bluetooth, th...
