[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be described below clearly and completely, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without paying creative labor belong to the protection scope of the utility model.

[0023] The multi-functional sound box with screen based on the scaler module of the preferred embodiment of the utility model, as shown in Figure 1 , and referring to Figure 2 And Figure 3, including a sound box body, a display module 1, an MCU 2, an audio power amplifier 3 and a loudspeaker 4 are arranged on the sound box body, and a Scaler module 5 is further arranged on the sound box body; the Scaler module 5 is connected with the MCU 2; the Scaler module 5 has a video input interface, an image output interface and an audio output interface, the display module 1 is connected with an image output interface of the Scaler module 5, the loudspeaker 4 is connected with the audio power amplifier 3, and the audio power amplifier 3 is connected with the audio output interface;

[0024] The application of the multi-functional sound box with a screen based on the Scaler module adds the Scaler module 5 on the existing sound box, the Scaler module 5 can control the display of the display module on the sound box body, and can also receive the externally input video signal, and play the processed signal on the display module and the loudspeaker, so that the display control function of the sound box is more abundant, the external display capability is increased, and the applicability of the sound box is improved;

[0025] In application, other display devices 6 can also be externally connected to the sound box, the display devices 6 are connected with the display module on the sound box body to realize multi-screen display, and the practicality of the sound box is further improved, and the specific method can be as follows:

[0026] When the HDMI or DP signal is connected, the Scaler module recognizes and displays the picture on the display module (the sound box itself display) through the rear output LVDS MIPI EDP VBOTTL video interface, and can also loop out the HDMI or DP video interface to other display devices. The display devices 6 and the display module 1 can be displayed in SST or MST mode through the OSD of the Scaler module 5, SST is the same picture for two display screens, and MST is different pictures for two display screens, which can be set by the signal source.

[0027] In addition, the sound box is provided with a USB switch, a USB HUB and a TP / touch screen, when the HDMI or DP signal is connected, the Scaler module 5 recognizes that there is no USB channel, so the Scaler module 5 controls the USB switch to switch to the USB-A channel, at this time, the signal source needs to be connected with the device by using the USB line, the USB signal is transmitted to the USB HUB, then to the MCU, and finally to the touch screen to realize touch feedback control, and USB peripheral devices can also be connected.

[0028] In order to improve the adaptability to the access signal, the video input interface is also provided with two Type C ports, and the input switching of the Type C signal is realized through the USB switch. Specifically, when the Scaler accesses the type C signal, Type C-A and Type C-B can be plugged in blindly. Assuming that Type C-A accesses the signal source, the Scaler module identifies the USB signal, so the Scaler module controls the USB switch to switch to Type C-A channel. Assuming that Type C-B accesses the signal source, the Scaler module identifies the USB signal, so the Scaler module controls the USB switch to switch to Type C-B channel. At this time, the USB signal is connected to the USB HUB, and then to the MCU, and then to the touch screen to realize touch reverse control. At the same time, USB peripherals can be connected. Since Type C-A and Type C-B can be plugged in blindly, the signal source can also be plugged in blindly. When any one channel is connected to the adapter, the battery is charged, and the board is powered at the same time. Assuming that one is connected to the adapter and one is connected to the signal source, the signal source can be reversely charged.

[0029] In addition, the sound box itself is configured with a battery 7 for power supply, and the MCU 2 processes the charging and discharging management of the battery 7, and informs the Scaler module 5 of the battery 7 power to display the current power and state on the OSD. It also initializes the wireless charging module 8, power management, and opens / closes.

[0030] In the case where no signal source is connected and the battery is powered, the power is turned on through the key on the MCU 2. At this time, it can be a power bank function, and the charging device can be connected to the USB HUB or the wireless charging module 8 for charging.

[0031] The sound box body is provided with a Bluetooth module 9 and a microphone, and the Bluetooth module and the microphone are connected with the audio power amplifier. The audio power amplifier has three inputs: 1. Bluetooth reception, 2. Microphone input, 3. Receive audio analyzed by the Scaler module to the loudspeaker. At the same time, the OSD controls the volume, tone and other audio adjustments of the Scaler module. The OSD can select the input channel, and the default receives the audio signal of the Scaler module.

[0032] It should be noted that the functions that can be realized by each of the above modules are the functions of the modules themselves, and the improvement of the computer program is not designed; preferably, the Scaler module can adopt models: RTD2785, RTD2795, etc. without brand limitation; the MCU can adopt models: GD32F303RCT6, etc. without brand limitation; the above models are only examples and are not used for model limitation. The skilled in the art can also use other models of chips with the above functions to replace them.

[0033] It should be understood that modifications or variations can be made according to the above description by those of ordinary skill in the art, and all such modifications and variations are intended to be within the scope of the present application as defined by the claims appended hereto.
