Abstract
The utility model discloses a kind of small high-definition multimedia interface with equalization function, comprise HDMI (High Definition Multimedia Interface) male joint, equalizer amplifier, power management chip, cable tap and keyset, described HDMI (High Definition Multimedia Interface) male joint is fixed in keyset upper end, and keyset front is located at by described equalizer amplifier, described cable tap is connected to keyset bottom, and described power management chip is located at the back side of keyset.The utility model has the small high-definition multimedia interface of equalization function, by power management chip being located at the back side of keyset, thus reduce area and the length of whole HDMI (High Definition Multimedia Interface), the length of whole joint is made to be less than 3cm, thus ensure, in work progress, to be easy for installation and maintenance.
Description
Technical field
The utility model relates to a kind of HDMI (High Definition Multimedia Interface), is specifically related to a kind ofly have equalization function and the HDMI (High Definition Multimedia Interface) of small volume.
Background technology
HDMI (High Definition Multimedia Interface) (English is called for short HDMI) is a kind of totally digitilized video and sound transmission interface, can send unpressed audio frequency and vision signal.HDMI (High Definition Multimedia Interface) can be used for the equipment such as box on machine, DVD player, PC, holder for TV playing, integrated amplifier, digital sound and television set.HDMI (High Definition Multimedia Interface) can send audio frequency and video-audio signal simultaneously, because audio and video frequency signal adopts same cable, enormously simplify the installation difficulty of system line.HDMI (High Definition Multimedia Interface) is designed to replace the audio-visual transmission interface of older simulation audio-video interface as special in SCART(mono-kind) or RCA(be commonly called as lotus flower head) etc. terminal.It supports all kinds of TV and computer video form, comprises SDTV, HDTV video pictures, adds multi-sound channel digital audio.When sending, various video data will be become data packet by HDMI (High Definition Multimedia Interface) transceiving chip with " transition minimized differential signaling " (TMDS) technology for encoding.
Meanwhile, along with popularizing of HDTV (High-Definition Television), the application of HDMI (High Definition Multimedia Interface) circuit is more and more extensive.Usually when wiring is greater than 10 meters, because signal attenuation is too fast, the signal quality of the HDMI (High Definition Multimedia Interface) cable not with equalizer is very poor, now, then needs its receiving terminal to provide equalization function.But for the chip of receiving terminal most of on market, its ability of equalization differs, and therefore display effect is different.Be difficult to the consistency ensureing whole system.Therefore for HDMI (High Definition Multimedia Interface) cable when being greater than 10 meters, quite a few system adopts the method for cable integrated equalizing device that signal quality is guaranteed.
On cable, integrated equalizing device undesirably increases the size of HDMI (High Definition Multimedia Interface).In the market, have the HDMI (High Definition Multimedia Interface) of equalization function, its length is greater than 5cm usually.This is in practice of construction process, because long HDMI (High Definition Multimedia Interface) is difficult to be shuttled back and forth wiring by pipeline, is not easy to use, and also comparatively inconvenience during maintenance.
Summary of the invention
The purpose of this utility model to solve the problems of the prior art, provides a kind of length shorter, in work progress, be convenient to installation, maintenance, and have the small high-definition multimedia interface of equalization function.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
A kind of small high-definition multimedia interface with equalization function, comprise HDMI (High Definition Multimedia Interface) male joint, equalizer amplifier, power management chip, cable tap and keyset, described HDMI (High Definition Multimedia Interface) male joint is fixed in keyset upper end, and keyset front is located at by described equalizer amplifier, described cable tap is connected to keyset bottom, it is characterized in that: described power management chip is located at the back side of keyset.
Compared with prior art, the utility model has the advantage of: the utility model has the small high-definition multimedia interface of equalization function, by power management chip being located at the back side of keyset, thus reduce area and the length of whole HDMI (High Definition Multimedia Interface), the length of whole joint is made to be less than 3cm, thus ensure, in work progress, to be easy for installation and maintenance.
Accompanying drawing explanation
Fig. 1 is the front elevational schematic that the utility model embodiment has the small high-definition multimedia interface of equalization function;
Fig. 2 is the schematic rear view that the utility model embodiment has the small high-definition multimedia interface of equalization function.
In figure:
1, HDMI (High Definition Multimedia Interface) male joint; 2, equalizer amplifier; 3, power management chip; 4, cable tap; 5, keyset.
Embodiment
Below in conjunction with accompanying drawing, introduce a kind of embodiment of the present utility model in detail.
As depicted in figs. 1 and 2, a kind of small high-definition multimedia interface with equalization function of the utility model embodiment, by HDMI (High Definition Multimedia Interface) male joint 1, equalizer amplifier 2, power management chip 3, cable tap 4 and keyset 5, HDMI (High Definition Multimedia Interface) male joint 1 is fixed in keyset 5 upper end, and keyset 5 front is located at by equalizer amplifier 2, simultaneously, power management chip 3 is located at the back side of keyset 5, and cable tap 4 is connected to keyset 5 bottom.
The utility model has the small high-definition multimedia interface of equalization function, by power management chip being located at the back side of keyset, thus reduce area and the length of whole HDMI (High Definition Multimedia Interface), the length of whole joint is made to be less than 3cm, thus ensure, in work progress, to be easy for installation and maintenance.
Below by reference to the accompanying drawings execution mode of the present utility model is explained in detail; but the utility model is not limited to above-mentioned execution mode; in the ken that those of ordinary skill in the art possess; can also make various changes and modifications under the prerequisite not departing from the utility model aim, these changes and improvements all fall in the protection range of the utility model requirement.
