Abstract
The utility model provides a television which comprises a left sound box, a right sound box and a middle sound box. A 5.1-channel decoding module decodes the 5.1-channel information from the signal source to six-channel independent audio signal which comprises left-channel signal, right-channel signal, middle signal, bass signal, left surround signal and right surround signal, wherein the left-channel signal, the right-channel signal and the middle signal are respectively output on the left sound box, the right sound box and the middle sound box; a bass sound box interface is used for receiving the bass signal and outputting the signal to a bass sound box; and a wireless transmitting module receives the left surround signal and the right surround signal and transmitting the signal to the left rear sound box and the right rear sound box.
Description
Technical field
The utility model relates to TV, relates in particular to the broadcast of television audio.
Background technology
Along with scientific and technological progress, increasing TV begins to support to contain the function of high definition decoding, as watches HDTV (High-Definition Television), plays the video file of high definition and play high definition recreation or the like.These high cleaning functions often provide the audio frequency of 5.1 sound channels, and have only and play the performance that 5.1 sound channels just can obtain the best.And traditional TV often only provides the left and right sides stereosonic function, can only be mixed into 2 sound channels to 5.1 sound channels.Do like this and can reduce effect, handle around the audio of a class even carried out some, also can't be identical with 5.1 real sound channels.Under existing situation, if the user needs the sound of 5.1 sound channels, often just need an extra power amplifier and one group of sound equipment bought, can increase substantially cost.It mainly is following reason that traditional TV does not provide 5.1 sound channels.The film source that at first is 5.1 sound channels is few, but along with the popularizing of high definition, comprises the generally use of HDMI interface on the TV, and it is used can be more and more.Next is the problem of putting position, because left and right sides sound equipment needs certain location interval, and rearmounted audio amplifier need be placed in the cause of back, often bad wiring.
The utility model content
The utility model purpose is to provide a kind of TV that carries 5.1 sound channels, thereby plays 5.1 channel audios.
For this reason, the utility model provides a kind of TV.This TV comprises: audio amplifier is put on a left side, audio amplifier and center-channel speaker are put in the right side; 5.1 the channel decoding module will become 6 tunnel audio signals independently from the decoding of 5.1 channel informations of signal source, comprise left channel signals, right-channel signals, center signal, bass signal, left surround signal and right surround signal; Wherein, left channel signals, right-channel signals and center signal output to respectively that a left side puts that audio amplifier, the right side are put audio amplifier and above the center-channel speaker; The woofer interface is used to receive bass signal and it is outputed to woofer; Wireless transmitter module receives left surround signal and right surround signal, and sends it to left back audio amplifier and the right back audio amplifier of putting put.
Adopt TV of the present utility model can play 5.1 channel audios voluntarily.In addition, along with the increase of present TV (such as liquid crystal) TV panel, it is between left and right apart from also enough satisfying distance separately, and the transmission by wireless mode, also can make rearmounted audio amplifier no longer be subjected to connect up perplex.
Description of drawings
Below with reference to accompanying drawings embodiment of the present utility model is described in detail, wherein:
Fig. 1 is the system construction drawing according to an embodiment of the present utility model;
Fig. 2 is a sound equipment position view on the TV; And
Position view when Fig. 3 is use.
Embodiment
Fig. 1 is the system construction drawing according to an embodiment of the present utility model.As shown in Figure 1, on traditional TV, at first add 5.1 channel decoding modules, the decoding of 5.1 channel informations of signal source can have been become 6 tunnel audio signals independently.Wherein, left channel signals, right-channel signals and center signal output to respectively that a left side above the TV puts that audio amplifier, the right side are put audio amplifier and above the center-channel speaker; Bass signal outputs to above the woofer interface of TV, links to each other with woofer by tone frequency channel wire again; Left surround signal and right surround signal are transferred to wireless transmitter module, and by wireless transmitter module signal are sent, and left back then audio amplifier and the right back audio amplifier of putting put is respectively by above-mentioned two signals of demodulate reception.The wireless-modulated mode that wireless transmitter module adopted can include but are not limited to FM modulation, 2.4G wireless transmission, bluetooth, WI-FI etc.
Fig. 2 is a sound equipment position view on the TV, has illustrated that specifically audio amplifier is put on a left side, audio amplifier and center-channel speaker position are on TV put in the right side.Wherein, the left side that sound equipment is positioned at display screen is put on a left side, and the right that audio amplifier is positioned at display screen is put on the right side, and center-channel speaker is positioned on the median vertical line of TV, can be positioned on the upper edge or lower edge of TV.In a preferred embodiment, a left side is put audio amplifier, the right side and is put in audio amplifier and the center-channel speaker one or several and can adopt flat panel speaker, so as with belong to dull and stereotyped liquid crystal or OLED TV etc. equally and on external form, mate.
Position view when Fig. 3 is use.As shown in Figure 3, woofer can link to each other with TV by wire signal, because bass does not have directivity, so can be placed on any position.And the left back audio amplifier of putting is right backly put left side and the right side that audio amplifier roughly is placed on the listener.Left backly put audio amplifier, the right back audio amplifier of putting can use ac power supply or the dry cell or the supply power mode of rechargeable battery.In an example, when the left back audio amplifier of putting, the right back audio amplifier of putting should enter holding state with saves energy when using the audio signal of the powered battery and 2.0 forms of televising.
Obviously, the utility model described here can have many variations, and this variation can not be thought and departs from spirit and scope of the present utility model.Therefore, the change that all it will be apparent to those skilled in the art all is included within the covering scope of these claims.
