1。 The volume setting of audio source or amplifier is too low. This is the simplest and most common reason, just turn the volumepotentiometer of the sound source or amplifier clockwise to the appropriateposition.

2。 The balancepotentiometer is not setproperly. The balancepotentiometer is used to adjust the balance between the left and right channels. If it is adjusted to one side, it will lead to little or no sound on the other side. At this time, just adjust the balancepotentiometer to the middleposition.

3。 Bad or damaged audio cable connection. Audio cable is an importantpart connecting the audio source and the amplifier. If the connection is not firm, broken or short-circuited, it will lead topoor signal transmission or loss, thus affecting the sound volume and quality. At this time, it is necessary to check and replace the audio cable and ensure good contact between theplug and the socket.

4。 The horn ispoorly connected or damaged. Horn is a component that outputs sound. If the connection is not firm or there is aphenomenon such as fracture or short circuit, the soundpressure will dropor it will notproduce sound, thus affecting the sound volume and quality. At this time, it is necessary to check and replace the horn, and ensure that the matching between the horn and the amplifier is reasonable.

5。 The internal circuit of the amplifier is faulty. If all the above reasons are eliminated, there is still no improvement, then there may be some faults inside the amplifier, such as capacitor aging, component damage, solder joint falling off and so on. This situation is complicated, which requiresprofessional inspection and maintenance.

is the voice of the mobilephone live broadcastprompt function too low?

There are two reasons why the speaker of mobilephone is low:

1. There are sundries in the speaker, such as deadly iron filings. If a large amount of iron filings are inhaled in the speaker, the sound of the mobilephone will be reduced even if it is good. You just need to take it to the mobilephone seller and ask the repairman to take it out (this is the safest, I’m afraid your mobilephone is still under warranty, so don’t disassemble it yourself. Besides, we don’t have some tools, or the speaker will be damaged)

2. Long-term use of loud volume on mobilephones is not good for the life of speakers, so don’t always turn the volume upto the maximum, even if you wear headphones, which is good for your hearing
