FIG. 1 is a diagram of an apparatus for managing audio output according to an embodiment of the present invention;
FIG. 2 is a flowchart illustrating an embodiment of managing audio output.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a diagram illustrating an apparatus for managing audio output according to an embodiment of the present invention. As can be seen from fig. 1, the apparatus for managing audio output is composed of an audio output detection module, an audio output decision module, and an audio output execution module, which are connected in sequence. The apparatus for managing audio output shown in fig. 1 is usually disposed in an Embedded Controller (EC) of a device such as a notebook computer and a mobile phone.
In practical application, the audio output detection module may apply the prior art to detect the external audio device (which may be a wireless device or a wired device). When detecting that an external audio device is accessed, the audio output detection module informs the audio output judgment module in modes of sending level, event and the like. When receiving the notice from the audio output detection module, the audio output judgment module sends out a prompt whether to carry out sound channel expansion on the audio output. When the user is informed of the prompt, a selection can be made as to whether to perform channel expansion on the audio output, and the selection is input to the audio output decision module. When the selection of whether to perform the channel expansion on the audio output is received, the audio output judgment module performs different operations according to different selections.
It should be noted that: or, a decision rule may be preset in an entity such as an audio output decision module, and the audio output decision module obtains the decision rule and directly determines whether to perform channel expansion on audio output according to the obtained decision rule. Such as: the decision rule is that the audio output is always subjected to channel expansion, so that the audio output decision module determines that the channel expansion of the audio output is required when the audio output decision module knows that an external audio device is accessed.
If the audio output is not subjected to the sound channel expansion, the audio output judgment module controls the audio output execution module to output the audio by adopting a current general mode, such as: the audio output judging module informs the audio output executing module to carry out external audio output in modes of sending level, event and the like, and the audio output executing module provides audio output to the accessed external audio equipment according to the notification of the audio output judging module and stops providing internal audio output to the internal audio equipment. If the audio output is subjected to the sound channel expansion, the audio output judging module informs the audio output executing module to carry out the sound channel expansion in the modes of sending level, event and the like, and the audio output executing module provides audio output to the accessed external audio equipment according to the notification of the audio output judging module; and the audio output judging module also adjusts the matched internal audio output according to the external audio output of the external audio equipment and informs the adjusted internal audio output to the audio output executing module, and the audio output executing module provides the internal audio output for the internal audio equipment according to the notice of the audio output judging module.
The operation of adjusting the internal audio output described above is typically performed for the channels of the audio output. The specific adjustment method is generally as follows: the audio output judgment module informs the audio output execution module of a sound channel not occupied by external audio output and sends an audio signal to the audio output execution module; the audio output execution module sends the received audio signal to the internal audio equipment, and also informs the internal audio equipment of the received unoccupied sound channel, and the internal audio equipment utilizes the informed unoccupied sound channel to carry out internal audio output on the received audio signal.
If a 5.1 channel is taken as an example, the adjustment to the internal audio output may be: after a rear left channel and a rear right channel are respectively allocated to two accessed external audio devices, the sound channels of the three internal audio devices are respectively adjusted into a front left channel, a front center channel and a front right channel from the original left channel, center channel and right channel, and the adjusted front left channel, front center channel and front right channel are used for internal audio output. In practical applications, the adjustment of the internal audio output may not be limited to 5.1 channels, but may be other multi-channels such as 7.1 channels, as long as the channel audio Integrated Circuit (IC) providing the audio signal can provide the corresponding multi-channels.
It can be seen from the above description that the apparatus and method for managing audio output provided by the present invention have the capability of performing channel expansion, and the channel expansion capability is not limited by the volume of the notebook computer, the mobile phone, and other devices, so that multi-audio output can be effectively provided, and the satisfaction of the user can be obviously improved.
