Description

1332173 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a computer switcher, and more particularly to a computer switcher having a function. [Prior Art]

What are you doing now? 'The commercially available computer switchers mainly use the computer keyboard, mouse and shirt image signals as the main switching and operation objects. Therefore, the attached sound channel 3 is also equipped with keyboard, mouse and video signals. Among the switching functions: It is only simple to zoom in and switch functions. If you want to control the audio signal, you can't change the selection and control through the electric ribs. ^ For example, the Republic of China Invention No. 253555 patent has been approved, that is, a computer switcher that supports the digital video interface is not disclosed, at least two or two, the interface 'connects to a plurality of computers; the user interface, even the money , and the display device; - the switching circuit, the connection path between the operations and the computers, and the - digital view I should be "the road, the servo interface receives the electricity one 4 two and display The transposed electronic signal will be transmitted to the operation and display via the user's digital video signal through the user's digital video signal. The patent can only support digital video. Interface, but no / edge effect processing function, is a flaw in the United States. Review, the shortcomings of the brain switcher, the present invention provides a brain switcher to improve the above shortcomings. Sound processing Wei computer switching port. ' /, using the original computer switcher in the main control of the crystal terminal and the converter to the sound signal to make the sounder function in the audio processing more = different design principles Let the electricity Brain switch _ switcher, computer-adjusted material with sound processing function, suppressing the multiplexer selection or switcher function, the computer 埠 sound signal channel, and the second is opened by all the computers Different minds (3) can 'adjust _ to - key two;; - main control chip, 4 S L7 knife for circuit, the other end is lightly connected to at least one Thunder · Li ii upper end · connected to at least - source H :i The knife is connected to the sound effect chip, and the main control 曰μ input device is switched, which can be used for the processing of the sound source switching circuit, the main control chip and the device switching computer audio and audio hybrid device. ;"Electric-end is 'connected two' to its end-to-the volume of the resistor network, the other g main control crystal == select = to; select the at least - the source of the audio input device = input Ϊ; ι 1332173 In order to enable the review committee to further understand the structure of the present invention, the detailed description of the drawings and the preferred embodiments is as follows.

The focus of the command is that the device switching circuit 30 is placed on the printed circuit board , =, the wafer 彳. The computer device output/input interface 4 is placed in the printing, and the eight ends are coupled to the device switching circuit 3〇, less-computer 100, wherein the number of _ brains (10) can be m to η to

In the present embodiment, for convenience of description, the two computers 100 and 200 are illustrated, but not limited thereto.芍J The sound effect chip 50 is placed on the printed circuit board 1 ,, where the brain switcher, by the sound effect chip 5〇, the = monthly package switching state has the function of sound processing; the sound effect chip 5 〇 connected to at least one audio source input device 95, such as but not limited to A-M# one; ^ 曰 / original input device 95 case event, play, CD player or other audio source to play UL input device 95 The number can be 1 shirt n, in the second / ^ for convenience of description _ with two audio source input devices 95, 96 as an example, but not limited to this. For the other rounds of the circuit, the circuit board 10 is placed on the printed circuit board 10, and it is divided into 30, and the control chip 20 can be used to switch the circuit circuit to the sound effect switching brush circuit board 10, respectively. The input device 95 or 96 sound source signal (4) 4th order ^ / quantity ^ job 7Q, for example, but less than can provide CK32 or above, the wheel / input interface 80 is placed on the printed circuit board 1〇1 | 2= Ϊί; The volume resistance scale 70, the other end is secret to the other two computers 2GGA = 1 in the embodiment for the convenience of explanation, the first knowledge, can be extended ^ ^ Ming ' but the familiar with the computer technology technicians The input interface is not, for example, 1~N) #I is connected to the computer device output/transmission interface 8G. In the example of the county, the electric moons 100 and 200 are described as an example, but the number may be increased as needed, for example, increased to N. The mounting device is respectively coupled to the main control chip 20 and the selection of the ϋΪΚΪΓ 切 献 健 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 95 . When the adjustment device hotkey is selected, Ϊϊϋί ί volume '· When the selection adjustment device 90 is one

Change SI In addition, the computer with the sound processing function of this case switches 5|in-the cow and the -mo-type sound to i

When the Qnl σΛ ッ switch mode is switched, the user can choose to adjust F 21 and slide! The U 阜 source signal switching action is synchronized with its keyboard cerebral palsy, so 'the computer switcher's power or ίίΐοίΛ J" (10) county resettlement 9_ such as the control panel for its keyboard 21, mouse selection switching work 1 疋 other _ switcher can not match. The effect is shown in Fig. 2', which shows the block diagram of the sound effect switching circuit 60 of the present invention. For example, the circle is coupled to the sound effect chip 5, and the sound circuit switching circuit 60 of the sound circuit is provided, and the schematic diagram of the switching of the sound source wheel pin = the chip 20 and the device switching power can be provided. The switching circuit 60 is provided with n~n coupled to the sound effect chip 5 respectively. The sound effect switching circuit 60 of the present invention can provide the sound source input device and the device switching device. Θ5 at the same time ~ η switch, you can also refer to Figure 4, its | will ^ = (connected to any 埠 after the output. Adjust the schematic. As shown, the stagnation network 70 provides volume Road 30, can provide selected sound = cymbal 20 and device switching power (adjustment), the volume resistor network ^, set 5 sound source signal processing?, level volume adjustment,: jingle, 32 or j It will turn out without any attenuation; 'The sound source will be reduced by half and output; when or 32%, the audio signal will be fully attenuated (ie muted) and output. If you choose 0 or 〇犄, the source signal will be compared. In the case of f-knowledge, the computer switcher is traditionally switched or replaced separately: the audio signal can only be selected with the computer's synchronized audio, and the random lion can be used as a separate ship, or (4) steps only for audio. - There is a θ effect power b adjustment:], every computer 璋 audio can be, - or switch integer or Use the number of buttons or press 纟彳f panel/bone motion to open the direct adjustment (32 or 6 is wrong for adjusting the signal, adjust to the most (four) voice scale, and the sound 2, the mix recording step is turned on. 》

Outside the channel, you can also use the same type of video in the same day. In addition to switching the single audio and using the audio signal channel of the above-mentioned audio computer, it is necessary to generate a volume of 3 weeks. Input wheel source selection: due to the input of the sound source signal. So the computer switcher can control how much
