Technical field
The utility model belongs to technical field of television sets, relates in particular to a kind of audio signal processing of TV programme.
Background technology
Television set is the requisite electronic product of every household; Be one of prevailing household electrical appliance; In the epoch of making rapid progress at present; Television technologies is in develop rapidly constantly, and various television products are also constantly updating, but the control of television set automatic volume this most basic functions but do not have big progress and innovation.At present; In different TV stations, its source of sound size is distinguished to some extent, some radio station loud; The sound of some TV station is little; So occur changing the problem that the sound size of television set also will and then be regulated behind the platform easily, and the sound size of only regulating STB sometimes is not sufficient to sound is adjusted to the audio (amount) of expection, also will regulates just and can produce a desired effect to the sound size of television set.
The utility model content
The utility model technical problem to be solved is to provide the audio signal processing of TV programme, is intended to avoid because each TV station's source of sound difference causes changing the phenomenon that need regulate the volume of STB and audio signal output equipment repeatedly behind the platform.
The utility model is to realize like this; A kind of audio signal processing of TV programme; Comprise a STB and an audio signal output equipment; Also comprise the balanced automatic control equipment of a volume; The audio signal input end of the balanced automatic control equipment of said volume is connected with the audio signal output end of said STB through an audio signal wire, and the audio signal output end of the balanced automatic control equipment of said volume is connected with the audio signal input end of said audio signal output equipment through an audio signal wire.
Further, the balanced automatic control equipment of said volume comprises:
One volume balanced unit is connected between said STB and the said audio signal output equipment;
The electronic sound volume regulon is connected with said volume balanced unit, regulates the size of the output volume of said volume balanced unit;
The power subsystem that is connected with said electronic sound volume regulon with said volume balanced unit.
Further, said power subsystem is connected with said STB through a USB interface.
Further, said power subsystem connects external power supply.
Further, said audio signal output equipment is an audio frequency power amplifier equipment.
Further, said STB also is connected with a vision signal output equipment through a video signal cable.
Further, said vision signal output equipment and audio signal output equipment are built in the television set.
The utility model compared with prior art need not to change the volume of regulating STB and television set behind the platform repeatedly, need not bear the suddenly big or suddenly small worry of sound of changing behind the platform again, realizes real intellectuality, particularly can avoid influencing other people at night.
Description of drawings
Fig. 1 is the configuration diagram of the audio signal processing of the TV programme that provide of the utility model embodiment;
Connection sketch map when Fig. 2 is the audio signal output equipment employing television set realization among Fig. 1.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model is divided into two-way with the audio signal of STB and vision signal and is sent to the audio signal output equipment that television set or audio frequency power amplifier equipment etc. have audio output function; Wherein, Vision signal directly exports audio signal output equipment to; Audio signal exports audio signal output equipment to after then carrying out equilibrium treatment through the balanced automatic control equipment of a volume again.
With reference to Fig. 1; The audio signal processing of the TV programme that the utility model provides comprises STB 1, the balanced automatic control equipment 2 of volume and audio signal output equipment 3; STB 1 is used for the audio-video signal of received television program, and audio signal output equipment 3 is used to export the audio signal of the TV programme that STB 1 receives.STB 1 is connected through the balanced automatic control equipment 2 of volume with audio signal output equipment; The transmission of the audio signal parts of program is looked in power supply; Particularly; The audio signal input end of the balanced automatic control equipment 2 of volume is connected with the audio signal output end of STB 1 through an audio signal wire A, and the audio signal output end of the balanced automatic control equipment 2 of volume is connected with the audio signal input end of audio signal output equipment 3 through an audio signal wire A again.The balanced automatic control equipment 2 of volume will be the audio signal of volume in preset range from the Audio Signal Processing of STB 1; And then export audio signal output equipment 3 to; Audio signal to signal source gives great volume is compressed the volume that makes its max volume can not surpass your setting; The smaller audio signal of signal source volume is carried out whole the amplification reach the volume that you want, can guarantee that the volume of the audio signal that audio signal output equipment 3 receives remains in the preset range.
Further; As shown in Figure 1, the balanced automatic control equipment 2 of volume comprises a volume balanced unit 21, electronic sound volume regulon 22 and power subsystem 23, and volume balanced unit 21 is connected between STB 1 and the audio signal output equipment 3; Be used for detection and adjusting to input signal; Take a sample a time period when input signal is on the weak side, whole signal be amplified to the volume rank that sets, when signal is bigger than normal with regard to reduced overall to the volume rank that sets; Electronic sound volume regulon 22 is connected with volume balanced unit 21; Be used to regulate the size of volume balanced unit 21 output volumes, power subsystem 23 connects volume balanced unit 21 and electronic sound volume regulon 22 simultaneously, act as the two power supply.
As shown in Figure 1, above-mentioned power subsystem 23 is connected with STB 1, from STB 1, obtains electric energy or obtains electric energy from power supply adaptor, specifically can adopt the connected mode of USB interface, can certainly directly connect external power supply through power supply adaptor and obtain electric energy.
Above-mentioned audio signal output equipment 3 can be for an audio frequency power amplifier equipment, like loud speaker, and power amplifier etc.
Further; STB 1 also is connected with vision signal output equipment 4 through a video signal cable V; This vision signal output equipment 4 can be built in the television set with above-mentioned audio signal output equipment 3; As shown in Figure 2, the audio signal of STB 1 exports in the television set 5 through the balanced automatic control equipment 2 of volume through audio signal wire A, and the vision signal of STB 1 exports in the television set 5 through video signal cable V.
The utility model through the output volume size that sets the balanced automatic control equipment 2 of volume after, just need not go again when changing platform again to use a teleswitch repeatedly and adjust the size of STB or tv volume, need not bear the suddenly big or suddenly small worry of sound of changing behind the platform again.Should be appreciated that the balanced automatic control equipment 2 of above-mentioned volume also can be built within the STB 1 or realization within the audio signal output equipment 3.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
