Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of computor-keyboard with audio amplifier, built in sound box is on keyboard body, and keyboard body is connected with host computer by unique connecting line.This computor-keyboard, while minimizing keyboard and audio amplifier take up an area space, decreases connecting line quantity, and has saved host computer socket.
To achieve these goals, the technical solution of the utility model is:
A kind of computor-keyboard with audio amplifier, comprise audio amplifier and keyboard body, described audio amplifier is arranged in the housing of keyboard body, and computor-keyboard is connected with host computer by USB connecting line, USB connecting line connects audio amplifier by DAC modular converter, and described audio amplifier is powered by USB connecting line.
Wherein audio amplifier is connected with host computer by same USB connecting line with keyboard body, namely host computer sends digital audio output signal by USB connecting line, digital audio output signal is converted to simulated audio signal by DAC modular converter, then broadcasted by audio amplifier, when keyboard has input, the input of keyboard is input to host computer by USB connecting line.
Above-mentioned sound signal is connected with host computer by sharing a USB connecting line with keyboard input signal, decreases the quantity of connecting line, also saves host computer socket; Above-mentioned USB connecting line can may also be wireless for wired, and this selects according to actual needs.
When not turning on light, be user-friendly to computor-keyboard, computor-keyboard is set up switch and LED, described LED is arranged on keyboard body, and LED is connected with switch by electrical lead, and described switch is in parallel with computor-keyboard internal circuit.
When needs use LED, controlled the switch of LED by switch; Because switch is in parallel with computor-keyboard internal circuit, when not using computer or computor-keyboard, still LED can be used.
Described keyboard body top offers groove, and described groove is provided with lid; Described LED is arranged in groove or on lid.Both can protect LED, this computor-keyboard also can be made more attractive in appearance.
Described keyboard body is built-in with LED, and button is translucent.
In order to expand the function of computor-keyboard, USB and/or SD socket and/or TF socket can also be set on keyboard body.
Described keyboard body is also provided with counter, and described counter is in parallel with the numeric keypad district internal circuit on the right side of computor-keyboard, and this counter is powered by independent current source or powered by charge power supply, and charge power supply can be charged in computer use procedure; Adopt power supply mode in this way can ensure still can use under the state of shut down of computer.
The display screen of described counter is LCDs.
The display screen of described counter is arranged on the upper right side of keyboard body.
Described keyboard body built-in microphone, linear convergent rate mouth, microphone input interface and audio outlet plug.
Compared with prior art, the beneficial effects of the utility model are: audio amplifier is arranged on keyboard body by this computor-keyboard, saves space, are connected, decrease wiring quantity, and saved computer socket by a USB connecting line with host computer; Keyboard body is also provided with LED, can facilitates use night; Owing to being provided with counter on computor-keyboard, make this computor-keyboard can also realize not relying on computer screen and software and carry out digital computation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be audio output signal of the present utility model flow to schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but embodiment of the present utility model is not limited to this.
Embodiment 1
As shown in Figure 1, 2, a kind of computor-keyboard with audio amplifier, comprises audio amplifier 1 and keyboard body 2, audio amplifier 1 is arranged in the housing of keyboard body 2, computor-keyboard is connected with host computer by USB connecting line 3, and USB connecting line 3 connects audio amplifier by DAC modular converter, and audio amplifier 1 is powered by USB connecting line.
Wherein audio amplifier 1 is connected with host computer by same USB connecting line 3 with keyboard body 2, namely host computer sends digital audio output signal by USB connecting line 3, digital audio output signal is converted to simulated audio signal by DAC modular converter, then broadcasted by audio amplifier 1, when the button of keyboard body has input, the input of computor-keyboard is input to host computer by USB connecting line 3.
