The Bluetooth speaker speakers should judge whether the quality is good based on the actual situation. From the perspective of the Bluetooth speaker speaker, we can judge by watching the size of the Bluetooth speaker, the paper sound circle and sensitivity of the use. Let me introduce these points one by one.

First, the Bluetooth speaker horn with unqualified size and unqualified size must be unqualified. The normal size is about 1mm positive and negative. Whether it is round, square, oval, rectangle Hoster Bluetooth speaker speaker.

Second, the paper sound ring used by the horn, because the power is different, the paper sound ring selected is different. If the power requirements are high, the high -temperature -resistant aluminum membrane material will be used to avoid high -temperature burning horn; Use ordinary paper tube to do.

Third, resonance frequency fO. The condition of the speaker will also affect the level of FO. If FO is high, it will cause the bass of the horn to come out. This situation is particularly obvious in audio.

Fourth, the DB value is the sensitivity we say. The sensitivity of the horn is mainly affected by the magnet and size of the magnet. Magnetic magnets are divided into magnets: Y25 and Y30, and magnets are divided into magnets of N35 and N38. In the same size, the DB value made by Y30 is higher than the DB value made by Y25, and the DB value made by N38 is also higher than the N35. Under the condition of cost permitted, select the larger magnet in the case of the material, and the sound of the speaker will be better.

So this also provides us with a certain judgment. We can determine the quality of this Bluetooth speaker speaker in these aspects when buying the Bluetooth speakers.
