每当我们欣赏一个音乐节目,或收看一部反映时代脉搏的记录片时,总离不开扬声器。随着科学技术的发展和人民文化生活水平的提高,人们对重放节目的高保真度要求将进一步提高,也就是说要求:重放设备的频带宽、失真小、动态范围宽以及方位感真实等。这与原有信号的记录,或转播设备,或重放设备的性能有关,但总少不了终端的扬声器。扬声器性能的好坏和正确使用很重要,它对音质效果往往起着决定性的作用。
Whenever we enjoy a music program, or watch a documentary that reflects the pulse of the times, the speaker can not be separated. With the development of science and technology and improvement of living standards of the people, high fidelity requirements for replaying programs will be further improved, that is to say, the requirements of the replay device are: wide frequency band, small distortion, wide dynamic range and real sense of position Wait. This is related to the recording of the original signal, or the performance of the repeater or playback device, but the terminal’s loudspeaker is always missing. The performance of the speaker is good and bad and the correct use is very important, it often plays a decisive role in the quality of the sound.
