Abstract
The utility model provides an HDMI wire equipped with an amplifier. The HDMI wire equipped with the amplifier comprises HDMI wire material and an input plug and an output plug which are arranged at two ends of the HDMI wire material, and further comprises the amplifier, wherein the amplifier is arranged at a position at seven tenths to eight tenths of the HDMI wire material near one side of the input plug. Amplification performance of the amplifier on the HDMI wire material can be realized, so audio and video signals which arrive the output plug are improved, and normal performance and high definition of sound and images played by the high definition input equipment are effectively guaranteed, and thereby a problem of transmission attenuation of high definition audio and video signals caused by over-long length of the HDMI wire material can be solved.
Description
[technical field]
The utility model belongs to high definition audio video connecting line technical field, relates in particular to a kind of HDMI line that is provided with amplifier.
[background technology]
At present, common employing HDMI line is on the market finished high definition audio transmission of video signals between output equipment (as DVD, host computer, mobile phone) and the input equipment (as display, HDTV (High-Definition Television), projector equipment); But these HDMI lines are because of the restriction of technology and product itself, cause HDMI wire rod length to make the high definition audio vision signal of transmission thereon decay occur, have a strong impact on the high definition audio vision signal, finally cause demonstration and the result of broadcast extreme difference of input equipment, even can't normally show and play.
[utility model content]
In order to solve the above-mentioned technical problem that exists in the prior art, the utility model provides a kind of amplifier has been located at 7/10～8/10 position of HDMI wire rod, thereby has solved because the long HDMI line that causes the problem of high definition audio video signal transmission decay of HDMI wire rod.
The technical scheme that the prior art problem that solves the utility model adopts is:
A kind of HDMI line that is provided with amplifier, include HDMI wire rod and input plug, the output plug of being located at these HDMI wire rod two ends, this HDMI line also includes amplifier, and described amplifier is located at 7/10～8/10 position near the described HDMI wire rod of described input plug one side.
Further, the length of described HDMI wire rod is 10 meters～20 meters.
Further, described amplifier includes shell, circuit board and signal and amplifies chip, described circuit board is located in the described shell, is welded with described signal on it and amplifies chip, and the input that described signal amplifies chip all is connected with the conducting of described HDMI wire rod with output.
Further, described signal amplification chip is that model is that MAX3815 amplifies chip.
The beneficial effects of the utility model are as follows:
The utility model passes through technique scheme, the amplification performance of its amplifier obtains maximum performance, make the AV signal that arrives output plug strong, guarantee the sound of high definition input equipment broadcast and normal, the high definition of image of demonstration effectively, thereby solved because the long problem that causes the decay of high definition audio video signal transmission of HDMI wire rod.
[description of drawings]
Fig. 1 is a kind of broken section structural representation that is provided with the HDMI line embodiment of amplifier described in the utility model.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in fig. 1:
The described a kind of HDMI line that is provided with amplifier of the utility model implementation column includes HDMI wire rod 1, input plug 2 and output plug 3, and described input plug 2 and output plug 3 are located at the two ends of this HDMI wire rod 1 respectively; This HDMI line also includes amplifier 4, described amplifier 4 is located at 7/10～8/10 position near the HDMI wire rod 1 of input plug 2 one sides, the length of this HDMI wire rod 1 is 10 meters～20 meters, this amplifier 4 includes shell 41, circuit board 42 and signal and amplifies chip 43, described circuit board 42 is located in the shell 41, be welded with signal on it and amplify chip 43, it can be that model is that MAX3815 amplifies chip (its structure and operation principle are given unnecessary details at this no longer in detail with existing identical that this signal amplifies chip 43.), and its input all is connected with 1 conducting of HDMI wire rod with output.
When HDMI line described in the utility model uses, directly input plug 2 is connected with the high definition input equipment with the high definition audio picture output device respectively with output plug 3, output equipment inputs to the high definition audio vision signal on the HDMI wire rod 1 through input plug 2 and transmits, when transferring to amplifier 4, the high definition audio vision signal is about to occur obviously decay, be delivered to again on the HDMI wire rod 1 after the AV signal of 4 pairs of inputs of amplifier this moment is amplified and transmit, make the AV signal that arrives output plug 3 strong, the image that guarantees sound that the high definition input equipment is play and demonstration effectively is normal, high definition, amplification performance at this process amplifier 4 obtains maximum performance, thereby has solved because the long problem that causes the decay of high definition audio video signal transmission of HDMI wire rod.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
