扬声器和扬声器系统 扬声器是将电信号转变为声信号并向空间辐射声波的部件.两只或多只扬声器和必需的扬声器箱、分频网络、衰减器等的组合称为扬声器系统.这时其中单只扬声器就称为扬声器单元.迄今为止,扬声器或扬声器系统仍然是高保真立体声系统中音质最不完善的环节.由于扬声器的品种很多,音质又涉及主观感觉,因此还没有明确的评价标准.但是人们只要把大口 Speakers and Speakers System Speakers are components that convert electrical signals into acoustic signals and radiate sound waves into the space. A combination of two or more speakers and the necessary loudspeaker boxes, crossover networks, attenuators, etc., is called the speaker system. The single speaker is called the speaker unit, so far the speaker or speaker system is still the most imperfect sound quality in high-fidelity stereo systems, and there is no definitive evaluation criteria due to the large variety of speakers and the subtle perception of sound quality.
