Furthermore, the particular features or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Referring to fig. 1 and 2, an educational all-in-one machine includes:
the integrated education machine comprises a sound box 100 and a display screen 200, wherein the integrated education machine is mainly applied to the field of education and can also be used in a meeting scene, the integrated education machine essentially has the functions of an electronic whiteboard, and a user can realize the functions of writing and the like on the display screen.
The display screen mainboard, the display screen mainboard connection has audio control subassembly 300, audio control subassembly includes at least one of volume control button, silence button and sound mode button. Generally, the driver board of the display screen can be understood, and in some embodiments, an android system is integrated with the display screen motherboard (generally, an android and windows dual system is adopted by a universal machine). It will be appreciated that the audio control assembly is comprised of physical buttons mounted on the surface of the device and processing circuitry, software, which undertakes the functions of button signal detection and signal processing based on the button signals.
And the OPS host is connected with the display screen main board through an HDMI interface. The OPS host is a dedicated host equipped with a windows system, and can perform communication through an OPS interface, in which various interfaces are integrated, of which HDMI is one. Of course, the OPS host can also be connected with the display screen main board through the HDMI cable alone. The interface referred to in this embodiment is not limited to its physical shape, but refers to a physical plug that satisfies some communication protocols.
The display screen mainboard adjusts the working state of the loudspeaker box according to the input signal of the audio control assembly, converts the input signal of the audio control assembly into a control instruction, and then sends the control instruction to the OPS host through a CEC pin of the HDMI interface, so that the OPS host adjusts the working state of the audio output channel. The operation state in this embodiment includes the volume, whether or not to mute, and the mode of output (e.g., treble mode, bass mode, etc.). It can be understood that the HDMI interface reserves the CEC pin as a pin for command transmission, which complies with the CEC communication protocol, and the OPS host can control the OPS host through the CEC pin based on the CEC pin and the communication protocol thereof. Only the OPS host needs to be configured to receive the CEC command at one end.
In some embodiments, the OPS host includes a plurality of audio output channels, wherein when the OPS host receives a control command transmitted through the CEC pin, the OPS host adjusts an operating state of each audio output channel. It can be understood that the OPS host can output through a plurality of beverage output channels, and in this embodiment, the CEC pin can be used to control the OPS host to synchronously adjust the operating states of the beverage output channels. For example, the OPS host may be connected to a bluetooth speaker and a speaker of the kiosk, and at this time, the audio control component of the kiosk mutes. Firstly, the sound box of the all-in-one machine can be muted, the OPS host is connected with the audio output channel of the sound box to be muted, and the OPS host is connected with the audio output channel of the Bluetooth sound box to be muted. Wherein, the mute of two audio output channels of the OPS host is controlled by CEC transmission instruction. It can be understood that, in some embodiments, when volume increase or decrease is implemented, the volume percentage may be synchronized, or may be increased or decreased by an equal amount according to the current state. In the synchronized state, for example, the current volume of the speaker is 50, the ops host is 65, the volume is increased by 1 through the button pair, the speaker is changed to 51, and the ops host is also changed to 51. In the case of non-synchronization, the enclosure becomes 51 and the ops master becomes 66. It can be seen that in some embodiments, the operational state of the OPS host audio output channel is synchronized with the operational state of the sound box.
In some embodiments, different audio output channels may be connected to different playback devices. The OPS host comprises a plurality of audio output channels, wherein after the OPS host receives the control command sent by the CEC pin, the working state of each audio output channel except the audio output channel connected with the display screen main board is adjusted. In these embodiments, the external sound source has higher priority than the internal sound source, and when the external speaker is connected, the external sound source of the OPS host serves as the only output channel. In the prior art, if a volume button on the all-in-one machine is adjusted, a user can only adjust the volume of the built-in sound box, so that the user can not feel response when pressing the button. Through the CEC control of this scheme, can convert volume control signal into control command, directly adjust OPS host computer and correspond audio channel operating condition for through the button on the all-in-one, can directly adjust external device's volume size.
In some embodiments, when receiving an input signal of an audio control component, the display screen main board sends a control instruction through the audio control component, so that the OPS host opens an audio output channel with the display screen main board. In some embodiments, the OPS host may be outputting audio through the external speaker, and in order to enable a user to quickly switch to the internal speaker, the audio control component may send a control command to the OPS host based on the CEC protocol, so that the OPS host converts an audio output channel connected to the display main board into a main channel.
In some embodiments, the audio control component further comprises a mode switch button, and the mode switch button corresponds to an operation mode of the display screen main board for turning on the CEC function and turning off the CEC function. It will be appreciated that direct control of the OPS host by the CEE function also causes problems, for example, audio increase and attenuation may have a superposition effect. Because the final output sound and the sound source size and the sound box output power size are in a product relationship within a certain range. Accordingly, a CEC function button may be provided to control the switching of the CEC function.
In some embodiments, in order to solve the problem of volume superposition gain and attenuation after the CEC function is started, when the display main board receives an input signal for continuously increasing the volume or continuously decreasing the volume, the audio output channel of the OPS host and the working state of the sound box are alternately adjusted according to the input signal. In this way, the volume of the audio output channels and the loudspeaker boxes can be alternately increased or decreased, which results in an increase in the number of steps of volume change experienced by the user, thereby smoothing the gain and attenuation curves. This embodiment is particularly effective in devices with a small number of adjustable stages. For example, according to the previous embodiment, the volume of the loudspeaker box is attenuated by 10%, and the output volume of the OPS host is also attenuated by 10%. In the embodiment, if the user continuously decreases the volume through the button, the output volumes of the loudspeaker box and the OPS host computer are alternately decreased, so as to avoid the above-mentioned superposition effect. The continuous adjustment referred to in this embodiment means that the volume is continuously adjusted in the same direction within a set time interval, i.e. the volume is continuously increased twice or the volume is continuously decreased twice.
In some embodiments, the buttons in the audio control assembly are disposed on the front, back, sides, or bottom of the kiosk.
