Abstract
The present invention provides a TV with an accompanying sound individual commutation function, which is mainly composed of a central processor TV-MCU of a TV, a decoder, a power amplifier and a loud-speaker. The present invention is characterized in that AV acoustic frequency signals are connected to the input end of the decoder; a TV signal TV is connected to the other input end of the decoder, and acoustic frequency signals outputted by the decoder are connected to an acoustic frequency amplifier through acoustic frequency signal wires; the output end of the acoustic frequency amplifier is connected with the loud-speaker, and the control signal end of the decoder is connected to the control signal output end of the central processor TV-MCU of the TV. The present invention has the accompanying sound individual commutation function. When people watch pictures of the TV, people can also listen to music recorded by a CD or music recorded by the music integrated module carried by the TV, or when people watch a video, a VCD or a DVD, people can also listen to the sound broadcast by the TV.
Description
Technical field
The invention belongs to the improvement of television set, is a kind of television set with independent sound switching function specifically.
Background technology
At present, the video and audio signal switch of television set is to link together, sound accompaniment just can be changed thereupon when having only video switch, raising along with people's living standard, practicality, interest, recreational requirement to television set are more and more higher, sometimes people are when seeing television image, want that music or the television set of appreciating the CD broadcast carry the music that the music integration module is play, perhaps when seeing video, VCD, DVD, want to listen to the sound of television for play, existing television set can't be realized these hopes of user, and this is that problem to be solved is arranged.
Summary of the invention
The purpose of this invention is to provide a kind of television set with independent sound switching function, has independent sound switching function, when seeing television image, music or the television set that can appreciate the CD broadcast carry the music that the music integration module is play, perhaps when seeing video, VCD, DVD, also can listen to the sound of television for play.
The objective of the invention is to be achieved through the following technical solutions: a kind of television set with independent sound switching function, mainly by TV central processing unit TV-MCU, decoder, power amplifier, loud speaker is formed, it is characterized in that: the AV audio signal is connected to an input of decoder, TV signal TV is connected with another input of decoder, the audio signal of decoder output is connected with an audio frequency power amplifier by audio signal wire, the output of audio frequency power amplifier is connected with loud speaker, and the control signal end of decoder is connected with the control signal output ends of TV central processing unit TV-MCU.
In the described television set with independent sound switching function Music Clip is arranged, the audio signal of Music Clip output is connected to the input that electronic switch is selected in a sound accompaniment, the AV audio signal is connected to another input that electronic switch is selected in sound accompaniment, and sound accompaniment selects the control end of electronic switch to be connected to another control signal output ends of TV central processing unit TV-MCU.
Described Music Clip can be one or more single Music Clips, also can be how bent Music Clip.
The present invention compared with prior art has many advantages and good effect:
1, the present invention selects electronic switch and music integration module by install sound accompaniment additional on television set.Make television set have independent sound switching function, when seeing television image, music or the television set that can appreciate the CD broadcast carry the music that the music integration module is play, and perhaps when seeing video, VCD, DVD, also can listen to the sound of television for play.Make that the performance of television set aspect audiovisual obtains expanding, improved practicality, the interest, recreational of television set.
2, simple in structure, easy to make, be convenient to implement and promote.
Description of drawings
Fig. 1 is general television set audio signal connecting circuit figure;
Fig. 2 selects commutation circuit figure for the sound accompaniment of television set of the present invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Referring to Fig. 1, among the general television set audio signal connecting circuit figure, comprise TV central processing unit TV-MCU1, decoder 2, TV/AV diverter switch 3, power amplifier 4, loud speaker 5 compositions.
Referring to Fig. 2, a kind of television set with independent sound switching function, mainly form by TV central processing unit TV-MCU1, decoder 2, power amplifier 4, loud speaker 5, the AV audio signal is connected to an input of decoder 2, TV signal TV is connected with another input of decoder 2, the audio signal of decoder output is connected with an audio frequency power amplifier 4 by audio signal wire, the output of audio frequency power amplifier 4 is connected with loud speaker 5, and the control signal end of decoder 2 is connected with the control signal output ends of TV central processing unit TV-MCU1.
In the described television set with independent sound switching function Music Clip 7 is arranged, the audio signal of Music Clip 7 outputs is connected to the input that electronic switch 6 is selected in a sound accompaniment, the AV audio signal is connected to another input that electronic switch 6 is selected in sound accompaniment, and sound accompaniment selects the control end of electronic switch 6 to be connected to another control signal output ends of TV central processing unit TV-MCU1.
Described Music Clip 7 can be one or more single Music Clips, also can be how bent Music Clip.
When the TV operate as normal, central processing unit TV-MCU1 sends control signal and gives decoder 2, makes decoder 2 receive the TV signal, output TV image and TV music; Perhaps make decoder 2 receive the AV signal, output AV image and AV music; (this signal is push button signalling both when central processing unit TV-MCU1 receives the sound accompaniment switching command, also remote signal), the software detection current state is TV or AV, if TV state, then send and control signal to decoder 2 inner particular addresss, make the sound accompaniment of decoder 2 switch to the audio signal of exporting by electronic switch 6, send control signal simultaneously and give electronic switch 6, select the music of AV sound accompaniment or Music Clip, at this moment, what people saw from screen is the TV image, and what hear then is the music that AV music or Music Clip 7 are play; If AV state, then send and control signal to the inner particular address of decoder, make the sound accompaniment of decoder 2 switch to the TV music, or send control signal and give electronic switch 6, make the output of electronic switch 6 change the music of Music Clip 7 into, at this moment, what people saw from screen is the AV image, and what hear then is the music that TV music or Music Clip 7 are play.The key of whole control process is to carry specific instruction to the inner particular addresss of decoder 2, makes it carry out sound accompaniment and switches and keep image constant, and the type of sound accompaniment is selected by switching electronic switch 6.
