What to do if there is no sound from the multimedia speakers

There are several reasons why multimedia speakers have no sound:

1. Check the input audio signal to see if it is not plugged in properly.

2. There is a problem with the audio cable. Try another one.

3. There is a problem with the power amplifier integrated circuit

4. Check the speaker connection cable

5. Check the speakers

If household appliances are not used for a long time, they will often get damp. It is better to open them frequently and use them. This situation may also be related to the quality of the audio system. Therefore, you must do your homework before choosing an audio system, listen to other people's suggestions, or go and try it directly. When choosing, I can give you some good suggestions for reference. First of all, let me tell you about BOSS and Maibo. The price of BOSS is ridiculously high, and the effect is not obviously proportional to the price. Some Maibo uses power-paired tubes, which have high power and are very shocking when watching movies, but the sound is not delicate enough. BT-audio Fengjin home theater will not have such problems. Fengjin is a classic sound quality home theater with pure British sound. The mid-bass unit adopts the integrated unit technology of gold cone and honeycomb basin. The mid-low frequency is strong and powerful, the sound directionality is particularly good, more condensed, clearer, and thicker, and the accurate sound phase and compact surround sense allow the listener to experience the wonderful sound field effect.

How to connect multimedia speakers to mobile phones

Whether the multimedia active speaker can be connected to the mobile phone depends mainly on whether there is an audio signal input interface on your multimedia active speaker, such as: AUX socket or lotus interface. If there is, you can connect it. Or whether the multimedia active speaker has Bluetooth function. If it has, you can directly search and pair it. If it does not have Bluetooth function, then you can buy an independent Bluetooth receiver on the Internet and then plug it into the USB flash drive. The connection method is as follows:

1. AUX jack, also known as headphone jack, can be connected to the multimedia active speaker with a 3.5MM audio cable at one end and to the mobile phone at the other end.

2. Lotus interface, that is, RCA socket, use a two-part audio cable, one end is a 3.5MM headphone plug, and the other end is two RAC lotus female sockets, connect it to the lotus interface on the multimedia speaker.
