[0052] According to an embodiment of the present application, a method for switching external sound channel of a display device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0053] Figure 2 is a flowchart of a method for switching external sound channel of a display device according to an embodiment of the present application, as shown in Figure 2 The method for switching external sound channel of the display device includes the following steps:

[0054] In step S202, the connection information of the external sound is obtained, wherein the connection information includes the connection number of the external sound and the current channel type of the external sound.

[0055] Optionally, the external sound can be a high-fidelity (HiFi) sound.

[0056] Optionally, the connection information can include the number of external speakers currently saved by the audio sending module of the display device, and the saved form can be the device ID, MAC address, etc. of the external speaker, which is not limited here as long as it can uniquely identify the external speaker.

[0057] Optionally, the channel type of the external speaker can include a left channel, a right channel, a subwoofer, etc.

[0058] In this embodiment, after the audio sending module of the display device is started, the information of the last paired external speaker saved by the display device can be automatically obtained, for example, the number of speaker pairing count and the device information of the paired speaker.

[0059] In step S204, when the number of connected external speakers is multiple, if it is determined that the current channel types of the multiple external speakers are all left channels or all right channels, channel switching prompt information is generated, wherein the channel switching prompt information is used to prompt the control on part of the multiple external speakers to switch the channels of the part of the external speakers.

[0060] In this embodiment, when the number of connected external speakers is multiple, the current channel types of the currently connected external speakers can be further determined; if it is determined that the current channel types of the currently connected external speakers are all left channels or all right channels, it is indicated that the channels of part of the external speakers need to be switched.

[0061] At this time, channel switching prompt information can be generated to prompt that the channels of part of the external speakers need to be switched, i.e., the channels of part of the external speakers are switched to left channels or right channels.

[0062] As can be seen from the above, in the embodiment of the application, after the audio sending module of the display device is started, the configuration information of the external speaker saved by the audio sending module can be obtained, i.e., the connection information; when the connection information indicates that the number of connected external speakers is multiple and the channel types of the multiple external speakers are all left channels or all right channels, channel switching prompt information is generated to switch the channels of the external speakers, which realizes that the channel type of the external speaker does not need to be set when the external speaker is shipped, achieves the purpose of configuring according to actual conditions in actual use, improves the flexibility of channel switching of the external speaker, and improves the user experience.

[0063] It is easy to note that, in the embodiment of the application, the channel type of the external speaker does not need to be set when the external speaker is shipped, and the channel can be switched according to the actual situation in subsequent use, which effectively overcomes the disadvantage that when the position of the external speaker is reversed, only the position of the external speaker can be adjusted, and improves the flexibility of use of the external speaker.

[0064] Therefore, the technical problem of a certain limitation that the position of the external sound equipment can only be adjusted when the position is reversed is solved by the technical scheme provided in Embodiment 1 of the present application.

[0065] According to the above-mentioned embodiments of the present application, the connection information of the external sound equipment can be acquired by: acquiring the current state of the audio sending module, wherein the audio sending module is arranged on the mainboard of the display device and is used to send the audio signal of the display device to the audio receiving module, and the audio receiving module is arranged on the mainboard of the external sound equipment; and acquiring the connection information of the external sound equipment when it is determined that the audio sending module is not abnormal based on the current state.

[0066] In this embodiment, the current state of the audio sending module of the display device can be acquired first, and if the current state is abnormal, it is determined whether the current state is in the pairing interaction interface; if the current state is in the pairing interaction interface, the application is prompted to pop up a prompt. If the current state of the audio sending module is not abnormal, the connection information of the external sound equipment is acquired.

[0067] According to the above-mentioned embodiments of the present application, the external sound equipment channel switching method of the display device can further include: if it is determined that the audio sending module is abnormal based on the current state, and if the current state is in the pairing interaction interface, the pairing interaction interface is used to display the abnormal information of the audio sending module, wherein the pairing interaction interface is used to display the pairing situation with the external sound equipment.

[0068] In this embodiment, if it is determined that the audio sending module is abnormal, the pairing interaction interface can be used to pop up a prompt, and the pairing situation of the external sound equipment can be known to the user through the prompt.

[0069] According to the embodiment of the present application, the number of external speakers is two, and the external speaker channel switching method of the display device further comprises: determining the channel configuration information of the two external speakers based on the connection information; when the channel configuration information indicates that the number of configured channels is one and the configured channel is the left channel, prompting the left channel connection success; when the channel configuration information indicates that the number of configured channels is one and the configured channel is the right channel, prompting the right channel connection success; when the channel configuration information indicates that the number of configured channels is two and the configured channels are both left channels, generating channel switching prompt information to prompt triggering the first button of the first speaker to switch the first speaker into the right channel mode, wherein the first speaker is the right speaker of the two external speakers, and the first button is used to control the first speaker to enter the right channel mode; when the channel configuration information indicates that the number of configured channels is two and the configured channels are both right channels, generating channel switching prompt information to prompt triggering the second button of the second speaker to switch the second speaker into the left channel mode, wherein the second speaker is the left speaker of the two external speakers, and the second button is used to control the second speaker to enter the left channel mode.

[0070] In this embodiment, the number of external speakers is two, and the channel configuration information of the two external speakers can be determined based on the connection information. Figure 3 The flowchart of the external speaker monitoring mechanism according to the embodiment of the present application is shown in FIG. 1, wherein after the display device is started, the monitoring mechanism is automatically entered, i.e., in the embodiment of the present application, the display device will start the monitoring mechanism after normal startup to monitor the state of the audio sending module TX. If the state of the audio sending module is normal, the device information of the audio receiving module of the paired external speaker is obtained. Figure 3

[0071] Since the types of the left and right speakers RX are consistent, the number of configured channels (L left channel, R right channel) can be used to confirm the current pairing status. Figure 3 ​As shown, if L+R<=1 and L=1, the application is notified of a left channel connection prompt; R=1, the application is notified of a right channel connection prompt; L+R=0, both left and right channels are connected to the failure prompt; if L+R>1 and L=2, the application is notified of a left channel connection of 2, please press the right sound R touch key; R=2, the application is notified of a right channel connection of 2, please press the left sound R touch key; L+R=2, the left and right channels are connected successfully, please press the left sound L touch key and the right sound R touch key to ensure better sound quality. Then the corresponding external sound normal or abnormal information can be displayed through the user interface UI; and it is judged whether the current is in the pairing interface, if not, in order to avoid the user not in front of the display device, the voice broadcast abnormal mechanism can be added to prompt the user. Otherwise, the corresponding device normal or abnormal information is displayed through the user interface UI. In this way, the connection status and channel configuration status of the external sound can be quickly and accurately obtained, so that the user can be prompted to switch the channel when the external sound connection or channel configuration is abnormal.

[0072] It should be noted that there is only one subwoofer for the subwoofer sound, so it can be monitored alone, and if there is no subwoofer channel, the application is notified of a subwoofer connection failure, otherwise it is normally connected.

[0073] According to the above embodiment of the present application, before obtaining the connection information of the external sound, the audio sending module can also be initialized, and the historical sound configuration information of the audio sending module is obtained, wherein the historical sound configuration information includes: the pairing number of the external sound in the historical time period, and the device information of the external sound with the pairing number; when the pairing number is greater than zero, the external sound with the pairing number is connected back.

[0074] Figure 4 It is a schematic diagram of the adaptive left and right channel pairing system of the display device according to the embodiment of the present application, as Figure 4 As shown, after the display device is normally powered on and started, the audio sending module can be initialized, and then the configuration information of the last external sound saved in the audio sending module (i.e. historical sound configuration information) is obtained, such as the pairing number count; and when Count>0, the audio receiving module RX device mode of the external sound is started through the wireless local area network to directly connect back to the external sound.

[0075] According to the above embodiment of the present application, the external sound channel switching method of the display device can also include: when the pairing number is zero, entering the pairing mode and performing the pairing operation in the pairing mode.

[0076] In this embodiment, when it is determined that the pairing number of the external sound is 0, the pairing operation is entered.
