Please also refer to Figure 2. FIG. 2 is a block diagram of the audio playing device 12 in FIG. 1 in an embodiment of the present invention. The audio playback device 12 includes: audio playback modules 200A- 200D , a network communication unit 202 and a processing unit 204 . Wherein, the audio playing modules 200A-200D include multiple sound channels.

In this embodiment, the audio playing module 200A is the main audio playing module to accommodate the network communication unit 202 and the processing unit 204 . The audio playing modules 200B- 200D are respectively extended audio playing modules, and are connected to the audio playing module 200A in a wireless or wired manner.

Wherein, the processing unit 204 is electrically coupled to the network communication unit 202 and can communicate with the main control electronic device 10 and the remote server 14 through the network communication unit 202 . According to the operation of the network communication unit 202 and the processing unit 204 , the audio playing modules 200A- 200D can receive the audio playing instruction 17 from the main control electronic device 10 , and play audio according to the audio data accessed from the remote server 14 . In more detail, the audio playing modules 200A- 200D can access the audio data of the remote server 14 through the Internet 16 to play audio according to the audio playing command 17 .

The operation mechanism of the network communication unit 202 and the processing unit 204 will be described in detail below.

The processing unit 204 receives the audio play command 17 from the main control electronic device 10 through the network communication unit 202 . In one embodiment, the processing unit 204 can obtain the address of the remote server 14 and the audio to be played selected by the main control electronic device 10 from the audio supply list 13 according to the selection input 15 according to the content of the audio playback instruction 17, such as the audio name or Title 110. In one embodiment, the audio to be played may be selected as the audio content of the audio data 110A- 110C corresponding to the audio name or title 110 .

The processing unit 204 then determines the "total number of channels" of the audio playing modules 200A-200D.

Each of the audio playback modules 200A-200D includes a different number of audio channels. For example, the audio playback module 200A can be a 3-channel module, the audio playback module 200B can be a 0.1-channel subwoofer module, and the audio playback modules 200C-200D are 1-channel modules respectively. Therefore, the total number of channels of the audio playing modules 200A- 200D is 5.1 channels.

The processing unit 204 further retrieves the channel data list 19 of the audio to be played from the remote server 14 through the network communication unit 202 according to the name or title of the audio to be played and the address of the remote server 14 . The channel data list 19 lists the audio data related to the audio name or title to be played and the corresponding specific channel number. For example, the audio data 110A- 110C all include the name or title of the audio to be played, but correspond to 2-channel, 5.1-channel and 9.1-channel respectively. Then the audio data 110A- 110C and the corresponding 2-channel, 5.1-channel and 9.1-channel will be listed in the channel data list 19 .

Therefore, according to the channel data list 19 and the total channel numbers of the audio playing modules 200A- 200D , the processing unit 204 retrieves audio data whose specific channel number matches the total channel number from the remote server 14 as selected audio data. Since the audio playing modules 200A- 200D are 5.1-channel, the processing unit 204 will retrieve the 5.1-channel audio data 110B as the selected audio data.

In another embodiment, the processing unit 204 can directly transmit the total channel numbers of the audio playback modules 200A-200D to the remote server 14 through the network communication unit 202, and then the remote server 14 transmits selected audio data according to the total channel numbers. 110B, so that the processing unit 204 receives the selected audio data 110B through the network communication unit 202 .

Further, the processing unit 204 controls the channels of the audio playing modules 200A- 200D to play audio according to the selected audio data 110B.

Therefore, the audio playback device 12 of the present invention can retrieve the audio data 110B corresponding to the total number of channels of its audio playback modules 200A-200D from the remote server 14 to play, avoiding the number of channels of the audio data and the audio playback modules 200A-200D The distortion caused when the total number of audio channels does not match, and the best playback effect can be obtained.

In one embodiment, the number of audio playing modules included in the above audio playing device 12 can be expanded or reduced. Therefore, the total number of audio channels included in the audio playback modules 200A- 200D may vary with the number thereof. For example, the audio playback device 12 only includes the main audio playback module 200A, and becomes a 3-channel system. In another example, the audio playback device 12 includes other extended audio playback modules besides the audio playback modules 200A- 200D, so as to become a system with more channels.

Therefore, in one embodiment, when the number of specific channels of the audio data 110A-110C stored in the remote server 14 does not match the total number of channels of the audio playback module, the processing unit 204 will send the audio data from the remote server 14 An audio data whose specific channel number is greater than the total channel number and closest to the total channel number is extracted as selected audio data.

For example, in addition to the audio playback modules 200A- 200D in the audio playback device 12 , two additional audio playback modules each with one channel may be additionally connected so that the total number of channels becomes 7.1 channels. However, the audio data 110A- 110C stored in the remote server 14 correspond to 2-channel, 5.1-channel and 9.1-channel. At this point, the processing unit 204 retrieves the 9.1-channel audio data 110C from the remote server 14 as the selected audio data to control the audio playback modules 200A-200D and the additionally connected two extended audio playback modules according to the selected audio channel. audio data 110C to play audio.

Therefore, when the processing unit 204 plays the selected audio data by extracting audio data whose number of specific channels is greater than the number of total channels, it can directly remove redundant channel data in the audio data, or convert more audio data The channel data is down-mixed into data having the same number of total channels. Compared with the practice of simulating more channel data with less channel data and creating insufficient channels out of nothing, this will avoid the sound distortion that is easy to occur when the number of specific channels is less than the total number of channels, and can Get the best playback effect. And, by extracting the audio data with the number of specific channels closest to the total number of channels as the selected audio data to play, it can avoid the waste of decoder resources and network bandwidth caused by the audio data with too high number of channels. Extra power loss, to achieve the best efficiency of hardware, network and power usage.

Please refer to Figure 3. FIG. 3 is a flow chart of an audio playing method 300 in an embodiment of the present invention.

The audio playback method 300 includes the following steps (it should be understood that the steps mentioned in this embodiment, except for those whose order is specifically stated, can be adjusted according to actual needs, and can even be executed simultaneously or partially simultaneously) .

In step 301 , the processing unit 204 receives the audio play instruction 17 from the main control electronic device 10 through the network communication unit 202 to obtain the address of the remote server 14 and the name or title of the audio to be played.

In step 302 , the processing unit 204 is enabled to confirm the total number of channels included in the audio playing modules 200A- 200D.

In step 303 , the processing unit 204 retrieves the audio data 110B whose number of specific channels is equal to the number of total channels from the remote server 14 via the network communication unit 202 .

If there is no audio data matching the total number of channels in the remote server 14, then proceed to step 304, the processing unit 204 retrieves audio with a specific number of channels greater than the total number of channels from the remote server 14 on the Internet through the network communication unit 202 Data 110C.

In step 305 , the processing unit 204 controls the audio playing modules 200A- 200D to play audio according to the audio data 110B or 110C.
