Abstract
The invention provides an HDMI (High-Definition Multimedia Interface) wire with an amplifier. The HDMI wire with the amplifier comprises an HDMI wire rod, an input plug and an output plug, wherein the input plug and the output plug are arranged at two ends of the HDMI wire rod; the HDMI wire also comprises the amplifier; and the amplifier is arranged at 7/10 to 8/10 of the position on the HDMI wire rod, which is close to one side of the input plug. Thus, the amplifying performance of the amplifier on the HDMI wire can be developed, so that strong audio and video signals of the output plug are achieved, and normal and high-definition voice and image played and displayed by a high-definition input device are effectively ensured, so as to solve the problem of transmission attenuation of high-definition audio and video signals caused by overlong HDMI wire rod.
Description
[technical field]
The invention belongs to high definition audio video connecting line technical field, relate in particular to a kind of HDMI line that is provided with amplifier.
[background technology]
At present, on the market common employing HDMI line is finished the transmission of high definition audio vision signal between output equipment (such as DVD, host computer, mobile phone) and the input equipment (such as display, HDTV (High-Definition Television), projector equipment); But these HDMI lines are because of the restriction of technology and product itself, cause the HDMI length of wires 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.
[summary of the invention]
In order to solve the above-mentioned technical problem that exists in the prior art, the invention provides and a kind of amplifier is located at 7/10～8/10 position of HDMI wire rod, thereby solved because the long HDMI line that causes the problem of high definition audio video signal transmission decay of HDMI wire rod.
The present invention solves the technical scheme that the prior art problem adopts:
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 amplification chip, described circuit board is located in the described shell, is welded with described signal amplification chip on it, and the input of described signal amplification chip and output all are connected with the conducting of described HDMI wire rod.
Further, described signal amplification chip is that model is the MAX3815 amplification chip.
Beneficial effect of the present invention is as follows:
The present invention passes through technique scheme, the amplification performance of its amplifier obtains maximum performance, make the AV signal that arrives output plug strong, effectively guarantee the sound of high definition input equipment broadcast and normal, the high definition of image of demonstration, 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 of the present invention.
[embodiment]
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in fig. 1:
The invention process is listed as described a kind of HDMI line that is provided with amplifier, includes HDMI wire rod 1, input plug 2 and output plug 3, and described input plug 2 and output plug 3 are located at respectively the two ends of this HDMI wire rod 1; 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 amplification chip 43, described circuit board 42 is located in the shell 41, be welded with signal amplification chip 43 on it, this signal amplification chip 43 can be that model is that (its structure and operation principle are with existing identical, and in this not go into detail for the MAX3815 amplification chip.), and its input and output all are connected with 1 conducting of HDMI wire rod.
When HDMI line of the present invention uses, directly input plug 2 is connected with output plug and is connected with the high definition input equipment with the high definition audio picture output device respectively, 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, again be delivered 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 effectively guarantees sound that the high definition input equipment is play and demonstration 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 is the further description of the present invention being done in conjunction with concrete optimal technical scheme, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
