The speaker is the terminal of the entire audio system. Its role is to convert audio energy into corresponding sound energy and radiate it to space. It is an extremely important part of the audio system, because it is responsible for turning the electrical signal into a sound signal for people's ears to listen to such a key task directly. Has a strong ability to distinguish the sound of complex sounds. Because the subjective feelings of human ears in sound are the most important criteria for evaluating the sound quality of a sound system, it can be believed that the performance of speakers plays a key role in the sound quality of a sound system. The audio manufacturer introduces the issues that need to be paid attention to in the use of speakers:

1. High -quality monitoring speakers are expensive, but do not think that using it can increase the quality of the program. In fact, it is a device that is a kind of hair picking. Not only does it have no modification ability to the program, but it will also expose many defects. The monitoring speaker does not have the powerful power, tolerance, and constant index characteristics of the expansion speaker. The sensitivity is much lower than that of the soundproof speaker and 

The maximum sound pressure level cannot be provided.

2. If the speaker works long for a long time, in the state of the maximum input power, the audio may cause the speaker to be burned due to the temperature reaching one Baidu. Therefore, there is a need to ensure that the input power that can work for a long time for a long time, that is, the rated input power is set. This data will be given in the data of the device. It is important to strictly implement it in use. In the case of the sound expansion effect, the sound expansion effect You should first consider changing the configuration instead of simply increase power.

3. If the speakers are not used properly, it is easy to cause howling. In order to reduce the scattering sound and increase the sharpness, try to point the function of the speaker in the direction of the audience.

4. Multiple speakers are often used at the same time at work. When connecting them, you must pay attention to polarity issues. All speakers should be the same. If the speakers after the connection are different, the sound output will interfere with each other. Insufficient, obvious irregularity.

5. The power between the amplifier and the speaker should be matched. The comprehensive sound quality of the replacement sound depends not only on the characteristics of the speaker, but also the output and load characteristics of the amplifier. If the sound is not ideal, don't just think that there is a problem with the speaker, but first of all, you should consider whether there is a problem with the magnifying system connected to it.
