　　How to distinguish the true and false treble of professional speakers

　　When customers buy professional speakers, they should not only pay attention to their stylish appearance, but also pay attention to the actual effect of the speaker's sound effects, and the distinction of high pitch is more important. How to distinguish between good and bad speaker treble? Three simple strokes: look, touch, and listen.

　　Look-there is a gap between the diaphragm and the panel. When planning speakers, many businesses continue to introduce a wide range of colorful, fashionable products, especially the high-pitched parts of some speakers are planned very beautifully and have characteristics. But precisely because of the beautiful appearance of these features, it also provides us with the key to distinguish the quality of the professional speaker's treble. It can be seen from the appearance that the problematic speakers are rough and shoddy, and some are more exquisitely manufactured. In terms of appearance, you can even use fake speakers. It is not so easy to distinguish them. In this regard, the best thing to do is to check whether there is a gap between the diaphragm and the panel. Generally speaking, because of the high-speed operation of professional speakers at high pitches, the diaphragm will oscillate. At this time, speaker manufacturers generally leave a gap between the diaphragm and the panel. On the contrary, it is difficult to see obvious gaps when the diaphragm and panel are bonded by glue or other methods.

　　Touch-the diaphragm feels soft. Touch the diaphragm with your hand, and feel a thin layer, soft to the touch, generally licensed. And some low-quality speakers made of other textures will feel blunt to the touch. In most cases, this trick is useful. Of course, pay attention to the intensity of the touch, and it is best not to be seen by the store. However, many manufacturers in order to protect the speakers, especially for fear of damage to the speaker diaphragm due to external impact, they will add a protective baffle outside the diaphragm, so that it is difficult for users to touch the diaphragm, let alone judge the speaker Is true and false.

　　Listen-the high-pitched voice is stable. Choose a song with richer treble to play. When you hear the treble, you need to pay attention to putting your ears closer to the professional speakers. At this time, listen carefully to see if the speaker will announce "chichi", "chirp" and other noises. Obviously, a noisy speaker indicates that the diaphragm is unstable and the effect of transmitting sound is not good, and its quality can be imagined. On the contrary, the treble performance is stable, and the professional speaker without noise is a product worth buying.
