The general purpose processor may be a microprocessor or the general purpose processor may be any conventional processor or the like.
It will be appreciated that the configuration shown in fig. 1 is merely illustrative and that the electronic device 1 may also include more or fewer components than shown in fig. 1 or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Referring to fig. 2, a method for adjusting power-on volume according to a preferred embodiment of the present invention is applied to an electronic device 1 including a first operating system and a second operating system, and the method includes steps S110, S120, and S130.
Step S110: and the first operating system and the second operating system execute starting operation.
When the electronic device 1 is started or after a period of time, the first operating system and the second operating system execute a starting operation. Optionally, the start duration of the first operating system is shorter than the start duration of the second operating system, and the first operating system completes the start before the second operating system completes the start. The first operating system may execute a boot operation before the second operating system, or may execute a boot operation after the second operating system, and the first operating system and the second operating system may also execute a boot operation simultaneously, which is not limited herein.
The electronic device 1 may be, but is not limited to, a mobile phone, a computer or a television. In this embodiment, the electronic device 1 is a television. The first operating system may be a time-sharing operating system, and the time-sharing operating system may be a Linux operating system or a Unix operating system. The second operating system may be, but is not limited to, an android operating system, a Microsoft operating system, or an IOS operating system. In this embodiment, the second operating system is an android operating system, and the start duration of the android operating system is longer than the start duration of the time-sharing operating system.
Step S120: and after the first operating system is started, playing the preset media file through the first operating system, adjusting the volume of the played preset media file according to the received volume adjusting signal, and storing the volume value.
The preset media file may be, but is not limited to, an audio file, a video file, or an advertisement. The volume adjustment signal may be, but is not limited to, an infrared volume adjustment signal, a bluetooth volume adjustment signal, a voice volume adjustment signal, a gesture volume adjustment signal, or a key volume adjustment signal.
Optionally, when the volume adjustment signal is an infrared volume adjustment signal, the first operating system includes a volume adjustment thread. In step S120: according to the received volume adjusting signal, adjusting the volume of the played preset media file may be: and the volume adjustment response thread responds to the infrared volume adjustment signal and adjusts the volume value of the preset media file played through the first operating system.
For example, after the first operating system is started, the first operating system has a volume adjustment thread running all the time, when receiving an infrared volume adjustment signal, the volume adjustment thread responds to the infrared volume adjustment signal and adjusts a volume value according to the infrared volume adjustment signal, and the first operating system calls an audio player in the electronic device 1 to play a preset media file after adjusting the volume value according to the adjusted volume value.
When the volume adjusting signal is a bluetooth volume adjusting signal, the electronic device 1 includes a bluetooth volume processing module. In general, the bluetooth processing module cannot directly adjust the volume value according to the received bluetooth volume adjustment signal, and therefore, when the volume adjustment signal is the bluetooth volume adjustment signal, the first operating system includes a volume adjustment response thread. The step of adjusting the volume of the played preset media file according to the received volume adjustment signal includes two substeps S122 and S124, please refer to fig. 3.
Substep S122: and the Bluetooth volume processing module receives the Bluetooth volume adjusting signal and converts the Bluetooth volume adjusting signal into a volume processing event.
Substep S124: and the volume adjustment response thread responds to the volume processing event and adjusts the volume value of the preset media file played through the first operating system.
The bluetooth volume processing module may be started when the electronic device 1 is powered on, or may be started after the electronic device 1 is powered on for a period of time. The bluetooth volume processing module may finish starting before the first operating system, or may finish starting simultaneously with the first operating system, as long as volume adjustment can be realized through the bluetooth volume processing module when the first operating system plays the preset media file, which is not specifically limited herein. Optionally, the bluetooth volume processing module includes a bluetooth protocol stack, and the bluetooth protocol stack can process a bluetooth volume adjusting signal.
For example, the bluetooth volume processing module converts the bluetooth volume adjustment signal into a volume processing event after receiving the bluetooth volume adjustment signal, where the volume processing event is an interrupt event with the highest priority. The volume adjusting thread can respond to the volume processing event preferentially to obtain a volume adjusting signal, the volume value is adjusted according to the volume adjusting signal, and the first operating system calls an audio player in the electronic equipment 1 to play a preset media file after the volume value is adjusted according to the adjusted volume value.
Step S130: and the second operating system acquires the volume value and sets the volume value as the volume value of the media file played by the second operating system.
The second operating system may acquire the volume value after the completion of the startup, or may acquire the volume value in the startup process, which is not specifically limited herein, as long as the volume value of the media file played by the second operating system is the volume value adjusted by the first operating system. The media files played by the second operating system may be, but are not limited to, video, music.
Through the setting, the electronic equipment 1 can realize volume adjustment after being started, and troubles caused by overlarge or undersize volume for a user due to the fact that the electronic equipment 1 adopts fixed volume or continues to use the volume when being shut down last time are effectively avoided. By adopting adjusting modes such as infrared volume adjustment and/or Bluetooth volume adjustment, the volume can be conveniently adjusted by a user, and the experience of the user is improved.
Because the starting completion time of the first operating system is different from that of the second operating system, the first operating system can call the data in the database corresponding to the first operating system when the starting is completed and the data needs to be called. Therefore, in this embodiment, optionally, the first operating system corresponds to a first database, and the second operating system corresponds to a second database. And the first operating system stores the volume value in a first database corresponding to the first operating system. In step S130: setting the volume value to the volume value of the media file played through the second operating system may be: and the second operating system acquires the volume value stored in the first database, sets the volume value as the volume value of the media file played by the second operating system and stores the volume value in a second database corresponding to the second operating system.
In order to avoid inconvenience to the user caused by the fact that the user needs to adjust the starting volume when restarting the electronic device 1. In this embodiment, the method may further include step S140: when the electronic device 1 is restarted, the first operating system obtains the volume value stored in the first database, and the volume value is used as the playing volume of the first operating system.
