Description
Technical field
The utility model relates to a kind of computer keyboard, refers in particular to a kind of MultiMedia Keyboard with acoustics.
Background technology
Traditional desk-top computer, its acoustics can only be on the table external or be built in the computing machine.In order to have better acoustics, most at present desk-top computers is to adopt external voice box, be the annexation figure between each parts of present common desk-top computer as shown in Figure 1, audio amplifier 1 ' and 2 ' independent on the table external is connected with main frame 3 ' by power lead, tone frequency channel wire.
There is following deficiency in this desk-top audio amplifier:
One, circuit connectivity problem: because each audio amplifier 1 ' and 2 ' all has the power lead of needs, tone frequency channel wire, this makes on the main frame 3 ' that just has more connecting line has originally increased more electric wire, not only connects trouble, and, numerous electric wires usually are intertwined, and also are unfavorable for cleaning and maintenance;
Two, engaged position problem: external voice box 1 ' and 2 ' has suitable volume, and it is big to take up room, and this makes and highlights crowdedly originally with regard to little table for computer, influences putting of computing machine.
In view of the above problems, there is improved necessity really in the acoustics of conventional desktop computer.
The utility model content
The purpose of this utility model is to provide a kind of MultiMedia Keyboard with acoustics, making things convenient for the connection of acoustic circuit, and reduces taking up room of acoustics greatly.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of MultiMedia Keyboard with acoustics, on keyboard, form installing space, compact horn unit and mini power amplifier are installed in this installing space, the power input of power amplifier directly is connected with the power lead of keyboard and output terminal is connected with loudspeaker unit, and the tone frequency channel wire of power amplifier is connected to main frame.
Above-mentioned installing space is formed on the left and right sides of keyboard end face, has two installing spaces, and two compact horn unit are installed in respectively in two installing spaces.
Connecting a tone frequency channel wire on the above-mentioned keyboard again is connected with a small-sized active mega bass case.
Connect an earphone cord on the above-mentioned keyboard again, for being connected with earphone.
Distribute to form five installing spaces on the above-mentioned keyboard, two loudspeaker about installing respectively in five installing spaces, mid-loudspeaker and two form 5.1 sound box systems thus around loudspeaker.
After adopting said structure, the utility model is compared with conventional desktop computer, because with the acoustics miniaturization and be installed in the keyboard, and directly utilize the power lead in the keyboard to power, so, only need a tone frequency channel wire to be connected with main frame, electric wire obviously reduces, and circuit connects very convenient, cleans, safeguards also very convenient, and, be built in the acoustics in the keyboard, taking up room of acoustics is reduced to zero, only need the space that is provided with of keyboard, do not take up room in addition, greatly facilitate putting of computing machine.

Embodiment
Shown in Fig. 2,3,4,5, be four embodiment of the MultiMedia Keyboard of being with acoustics of the utility model announcement.
On keyboard 1, form installing space 11, the concrete formation position of installing space 11 can be that the right side side of keyboard 1 is (as Fig. 2-5, has only one), also can form two (, having two) on two angles above about keyboard 1 as Fig. 6,8, also can be above keyboard 1 left and right and slightly middle part form three (as Fig. 7,9, have three), also can four angles of keyboard 1 and above in the middle of (, having five), perhaps other suitable position as Figure 10.
Cooperate shown in Figure 11, compact horn unit 12 and mini power amplifier 13 are installed in this installing space 11, the power input of power amplifier 13 directly is connected with the power lead of keyboard 1 and output terminal is connected with loudspeaker unit 12, and the tone frequency channel wire 15 of power amplifier 13 is connected to main frame 3.Wherein, keyboard 1 shown in Figure 2 adopts usb 14 to separate with tone frequency channel wire 15, and have tone frequency channel wire in the keyboard 1 employing usb 14 shown in Figure 3, usb 14 or 141 has the power delivery function, so, using 14 need of interface shown in Figure 2 tone frequency channel wire 15 to be inserted on the sound card of main frame 3 can use, and uses 141 need of interface shown in Figure 3 that software and driver is installed in main frame 3 and can realize that the connection of keyboard 1 uses; Keyboard 1 shown in Figure 4 again adopts PS/2 interface 140 to separate with tone frequency channel wire 15, and have tone frequency channel wire in the keyboard 1 employing PB/2 interface 142 shown in Figure 5, PS/2 interface 140 or 142 also has the power delivery function, using 140 need of interface shown in Figure 4 tone frequency channel wire 15 to be inserted on the sound card of main frame 3 can use, and uses 142 need of interface shown in Figure 5 that software and driver is installed in main frame 3 and can use.
Like this, the utility model is loaded onto compact horn unit 12 and mini power amplifier 13 on original keyboard 1, and it can effectively be amplified the audio signal of main frame 3 and reset.This structure is compared with conventional desktop computer, and it is very convenient that circuit connects, cleaning, safeguard also very convenient, and, taking up room of acoustics is reduced to zero, only need the space that is provided with of keyboard, do not take up room in addition, greatly facilitate putting of computing machine.
