Abstract
The utility model discloses a video-audio signal transferring controller which comprises a shell body, a socket and a plurality of piano-key switches. The socket is used for being inserted by an external antenna, the input antenna of a TV, the radio-frequency input and output wires of a videoplayer, the output wires of the right and left acoustic ducts of a karaoke machine, the output wires of the right and left acoustic ducts of a radio and a recorder, the input wires of right and left sound boxes, and is arranged on the shell body. The piano-key switches are assembled in the shell body, connected at definite logical relationship. The mutual connecting types of each of the input and output wires can be conveniently altered by the definite logical relationship of the piano-key switches. The utility model has the advantages of complete converting functions, convenient operation and direct viewing, can not only realize the conversions of a TV and a karaoke machine, a TV and a videoplayer, a TV and a videorecorder, and a TV and a computer for games, but also realize the share of a sound box, a videoplayer, a videorecorder and a karaoke machine.
Description
The utility model relates to a kind of video/audio signal switching controller that can conveniently change various household electrical appliance inputs, output interconnected relationship.
Along with the raising of family life level, television set, videocorder, radio-cassette player, karaoke machine, electronic game machine etc. enter most of families in succession.Yet people also can feel some regrets sometimes when these high-grade household electrical appliances of appreciation bring enjoyment.That is exactly to plug cable continually to change connecting mode, is hell to pay, too inconvenient really.Sometimes can the wrong circuit because of being unfamiliar with also, so that cause machine breakdown.
For addressing the above problem, occurred in the market severally looking, audio signal switching device.The game machine bidirectional transducer with toggle switch control going along with for example, it can only realize the conversion of two machinery compartments, and translation function is single, and practicality is lower; Also having a kind of also is the transducer of controlling with a toggle switch, it can realize the conversion between television set and OK machine, videocorder, the game machine, but can not make audio amplifier and radio-cassette player shared, this is concerning some wish the family of frequent music appreciating, and its function also is not up to expectations.In addition, the conversion equipment of this kind structure, operate not directly perceived, misoperation sometimes.
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides the video/audio signal switching controller of the complete and operation intuitive and convenient of a kind of translation function.
The purpose of this utility model be achieved in that it be convenient to the jack of pegging graft on comprising a housing and being arranged on housing with radio frequency input, output line, game machine output line, OK machine left and right acoustic channels output line, radio-tape recorder left and right acoustic channels output line, the left and right sides audio amplifier incoming line of external antenna, television set input aerial, videocorder and be assembled in the housing by certain logical relation is connected make it conveniently to change above-mentioned each import, a plurality of piano key switches of the mutual connected mode of output line.By by different buttons, can realize a kind of different translation function.
For the phase mutual interference of anti-stop signal, guarantee the reliability of work, upper and lower both sides are provided with the screen made from tin platinum paper in housing.
Advantage of the present utility model is that translation function is complete, except realizing the conversion between television set and OK machine, videocorder, the game machine, can also make audio amplifier and radio-tape recorder and OK machine shared, replace toggle switch with piano key switch, bring convenience to operation, and more directly perceived.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model electrical schematic diagram.
Fig. 3 is the utility model application example.
With reference to the accompanying drawings, the utility model is made of housing 7, upper and lower screen 8, external antenna jack D1, videocorder radio frequency input jack D2, television set input aerial jack D3, videocorder radio frequency output plughole D4, game machine output plughole D5, OK machine L channel output plughole CZ1, left voice box input jack CZ2, radio-cassette player L channel output plughole CZ3, OK machine R channel output plughole CZ4, right voice box input jack CZ5, radio-tape recorder R channel output plughole CZ6 and five piano key switch K1-K5.Each key all has four movable contact springs, six pairs of contacts, i.e. 1-6,1 '-6 '.Not during button, movable contact spring is on top, contact 1 and 2,1 ' with 2 ', 4 and 5,4 ' with 5 ' often connect, 2 and 3,2 ' with 3 ', 5 and 6,5 ' with 6 ' normal off, during by next key, this key back contact disconnects, normal off point connection, other key resets.The K1 key is the button that directly televiews, and presses this key, and its back contact disconnects, normal off point 2 and 3,2 ' with 3 ' connection, external antenna 9 links to each other with television set 10 antenna inputs through jack D1, D3 at this moment, turning on television set can teleview.
The K2 key is for watching video shows or while seeing that TV records down the TV programme button, press this key, its normal off point 2 and 3,2 ' with 3 ', 5 and 6,5 ' with 6 ' connect, the radio frequency input jack D2 that is external antenna 9 jack D1 and videocorder 11 connects, videocorder 11 radio frequency output plughole D4 and television set 10 antenna input jack D3 connect, turn on television set and videocorder this moment, can watch the TV programme that receives by videocorder, but programs of interest is recorded while seeing, also can insert video tape at any time, appreciate video program.
The K3 key is for appreciating the Karaoke button, connect down this key, its normal off point 5 and 6,5 ' with 6 ' connect, be that videocorder radio frequency output plughole D4 and TV set aerial input jack D3 connect, OK machine 12 left and right acoustic channels output plughole CZ1, CZ4 connect with left and right audio amplifier input jack CZ2, CZ5 respectively (by K5 key back contact 1 and 2,1 ' with 2 ' and 4 and 5,4 ' with 5 ' connection).At this moment, turn on television set, videocorder, OK machine and can appreciate Karaoke.
The K4 key is the machine of operating video games 13 buttons, press this key, its normal off point 5 and 6,5 ' with 6 ' connect, be that game machine 13 output plughole D5 and television set 10 antenna input jack D3 connect, this moment, television set separated with other electrical equipment, and directly link to each other with the game machine output, turning on television set and game machine can operate video games.
The K5 key is for appreciating program of radio station or audiotape button, press this key, its back contact 1 and 2,1 ' with 2 ', 4 and 5,4 ' with 5 ' disconnect, normal off point 2 and 3,2 ' with 3 ', 5 and 6,5 ' with 6 ' connect, this moment OK machine left and right acoustic channels output with about two audio amplifiers 15,16 disconnect, and radio-tape recorder 14 left and right acoustic channels outputs respectively with about two audio amplifiers 15,16 connect, open radio-tape recorder 14, sound can be emitted from audio amplifier 15,16.
