Description
技术领域 technical field
本实用新型涉及一种电缆，特别是一种音箱电缆的结构，属于电缆技术领域。 The utility model relates to a cable, in particular to a structure of a speaker cable, and belongs to the technical field of cables.
背景技术 Background technique
现有的广播音频传输电缆，屏蔽性能、柔软性差，不抗扭，强度低，不抗拉，电缆与设备不相匹配，音频数据传输信号较差，使用寿命较短，不能满足使用要求。在音响设备系统中的数字设备之间的信号传输必须用线缆互连，不论是什么制式、应用什么格式的系统设备，所用线缆至关重要，有时在某一环节忽略了线缆的交流特性，没有选用合理达到交流特性匹配的音频电缆，就不能达到最佳的技术特性效果，会产生不可想象的不良后果。为了精确地传输信号，电缆必须与发送和接收设备相匹配。数字电信号频率很高，特性阻抗匹配时电流在导线上的集肤效应会较深，越深传输效果越好。不匹配时集肤会越浅，传输效果也就越差，这是由于在电缆中大多电流形成反射，会产生驻波而消耗信号能量，使数字脉冲信号波形产生畸变。由于电缆阻抗不匹配时电缆中的分布电容、分布电感、电阻都能直接影响信号中的频率响应，影响脉冲的上升沿和下降沿时间，在传输接收端，对数字信号的解读时会出现误码，如果脉冲上升沿时间和下降沿出现时间上的前后偏移，会造成抖动时间长而降低了音频的质量，甚至会产生噪声使音质劣化。 The existing broadcast audio transmission cable has poor shielding performance and flexibility, no torsion resistance, low strength, no tensile resistance, the cable does not match the equipment, the audio data transmission signal is poor, and the service life is short, which cannot meet the use requirements. The signal transmission between digital devices in the audio equipment system must be interconnected by cables. No matter what system or format the system equipment is used in, the cables used are very important, and sometimes the communication of cables is ignored in a certain link. If you do not choose an audio cable that reasonably matches the AC characteristics, you will not be able to achieve the best technical characteristics, and unimaginable adverse consequences will occur. For accurate signal transmission, cables must be matched to the sending and receiving equipment. The digital electrical signal frequency is very high, and the skin effect of the current on the wire will be deeper when the characteristic impedance is matched, and the deeper the transmission effect, the better. When there is no match, the skin will be shallower, and the transmission effect will be worse. This is because most of the current in the cable is reflected, which will generate standing waves and consume signal energy, distorting the digital pulse signal waveform. When the cable impedance does not match, the distributed capacitance, distributed inductance, and resistance in the cable can directly affect the frequency response in the signal, and affect the rising and falling edge times of the pulse. At the transmission and receiving end, there will be errors in the interpretation of digital signals. Code, if there is a time shift between the pulse rising edge and the falling edge, it will cause long jitter time and reduce the quality of the audio, and even generate noise to degrade the sound quality.
