一般人会认为是音量开得太大声了音响的扬声器会受不了,因而把扬声器弄坏,其实不然,有许多种情况都可能,而且,有错误的概念。下面就来讲讲原因吧。
Most people will think that the volume is turned on too loudly, and the loudspeaker of the stereo will be unbearable, so it will damage the loudspeaker. In fact, it is not true. There are many situations that are possible, and there are wrong concepts. Now let's talk about the reasons.
1、音箱与功率放大器配置不合理
1. Unreasonable configuration of speaker and power amplifier
音箱的额定功率,一般音箱标明大粉红噪功率,也就是说,音箱的额定功率是指粉红噪声或宽频带能承受的模拟信号功率。
The rated power of speakers, generally professional speakers marked with large pink noise power, that is, the rated power of speakers refers to pink noise or analog signal power that can be borne by broadband.
一只分频点为1.6办贬锄、额定功率为100奥的二分频音箱,在额定功率时,低音单元可分配到78奥的输出功率,而高音单元仅分配到22奥。
A two division loudspeaker with a frequency division point of 1.6kHz and a rated power of 100W. At rated power, the bass unit can be allocated an output power of 78W, while the tweeter unit is allocated only 22W.
因此,对该音箱施加100奥的粉红噪声功率或普通节目信号功率,它可以承受;而用100奥的单频信号去测试时,无论高音和低音单元都有可能损坏。
Therefore, if 100W pink noise power or ordinary program signal power is applied to the speaker, it can withstand; When using 100W single frequency signal to test, both treble and bass units may be damaged.
2、分频器使用不当
2. Improper use of frequency divider
输入端分频点使用不当,或扬声器工作频率范围不合理也是导致高音单元损坏的一个原因。在使用分频器时,应严格按厂家提供的扬声器工作频率范围来合理的选择分频点。高音扬声器的分频点如果选择偏低,承受功率负担过重,就很容易烧毁高音单元,中音号筒也是如此。
Improper use of the frequency dividing point at the input end or unreasonable working frequency range of the loudspeaker is also a cause of damage to the tweeter. When using the frequency divider, the frequency division point should be reasonably selected in strict accordance with the working frequency range of the loudspeaker provided by the manufacturer. If the frequency division point of the tweeter is selected too low and the power burden is too heavy, it is easy to burn the tweeter unit, and so is the Alto horn.
3、均衡器调试不当
3. Improper equalizer debugging
山东音响厂家认为均衡器的调整也是关重要的。频率均衡器是为了补偿室内声场的各种缺陷和扬声器的各频率不均匀而设置的,应该用实际频谱分析仪或用其它的仪器进行调试。调试后的传输频率特性应在一定范围内是比较平坦的。
Shandong audio manufacturers believe that the adjustment of equalizer is also crucial. Frequency equalizer is set up to compensate for various defects of indoor sound field and uneven frequencies of speakers. It should be debugged with an actual spectrum analyzer or other instruments. The transmission frequency characteristics after commissioning should be relatively flat within a certain range.
在设计音响系统时,功率放大器在音响系统的设计功率上符合上述原则。只有音箱和系统的所有设备配合好,才能充分发挥音响功能。更多相关内容就来我们网站
