Abstract

The utility model discloses an amplification connecting line for a high-definition multimedia interface (HDMI) line. The amplification connecting line comprises an amplifier connected to an input end of an HDMI connecting line and an output plug at an output end of the HDMI connection line. The amplifier comprises a housing, a signal amplification chip and a circuit board. The signal amplification chip is arranged on a bottom surface in the housing, and a top end of the signal amplification chip is provided with the circuit board. An output end of the amplifier is provided with an input jack. The beneficial effects are that the output end of the large-length HDMI line for transmitting high-definition video and audio signals is inserted in the input jack of the amplifier; the amplifier is used for increasing high frequencies; and zero compensation signal attenuation can be generated after long-distance transmission to increase high frequency gain, and then the signals are sent to output equipment such as a display, a projection, a high-definition television through the output plug.
本实用新型公开了一种高清晰度多媒体接口线的放大连接线,包括连接于一HDMI(高清晰度多媒体接口)连接线的输入端的放大器及输出端的输出插头,放大器包括外壳、信号放大芯片及电路板,信号放大芯片设置于外壳内底面,信号放大芯片顶端设置电路板;放大器的输出端设有输入插口。本实用新型的有益之处是:在传输高清视音频信号的大长度HDMI线的输出端插入放大器输入插口,通过放大器增加高频,将经过长距离传输后能产生零点补偿信号衰减以增加高频增益,再由输出插头将信号传输至显示器、投影仪、高清电视等输出设备。
