The use of the Bluetooth speaker speaker is relatively relatively many. We all know that the wired speakers are more troublesome to use. Sometimes it will be more hindered. Then whether there is a failure of the Bluetooth speaker speaker, you can judge by several methods.

1. The audition check method is to connect the speaker to the output end of the power amplifier, and subjectively evaluate the quality of its quality by listening to the sound.

2. The use of a multimeter to detect the speaker is also rough.

3. Measure the DC resistance: Use the R*1 gear to measure the DC resistance between the two pins of the speaker, which should be slightly smaller than the nameplate speakers. For example, the resistance of 8 ohm's speakers is about 7 ohms. The measured resistance value is infinite, or the nominal impedance value is far greater than its name, indicating that the speaker has been damaged.

4. Listening to the sound of Kalacara: When measuring the DC resistance, the pins will be dismissed by a gauge. You should hear the sounder to make the sound of Kalacara. The loud, the better. Stuck.

5. A intuitive inspection: Check the phenomenon of paper basin rupture of the speaker.

6. Check the magnetism: Try the magnetism of the magnet with a screwdriver. The stronger the magneticity, the better.

These are the aspects of checking whether the Bluetooth sound box speakers have faults. The failure check of the Bluetooth speaker speaker can be found better in time, and adjusts and solve it.
