For many young people, Bluetooth speakers are important partners in life. Whether it's leisure, cooking or doing housework, connecting speakers to play soft or dynamic music is a great pleasure in life. However, with the development of science and technology, the types and brands of Bluetooth speakers are also increasing. How to choose has become a big problem, so think, let's learn about it together.domestic bluetooth speakerHow to choose!

1. how to choose a domestic Bluetooth speaker

1. Compatibility

Although the compatibility of domestic Bluetooth speakers can basically support existing Bluetooth devices, it is still necessary to check whether your playback device supports Bluetooth before purchasing.

2. Transmission distance

The transmission distance of domestic Bluetooth speakers is also a concern. The transmission distance of the Bluetooth speaker has nothing to do with the Bluetooth version. It mainly depends on the advanced level of technology, which increases the transmission distance to 100 meters and provides a Hi-Fi stereo effect. Generally speaking, the distance between the mobile phone and the Bluetooth speaker should not be too far, and the safe transmission distance is about 10 meters. Bluetooth speakers on the market have reached the standard of 10 meters.

3. Version

When consumers buy Bluetooth speakers, they often see Bluetooth 1.1, 1.2, 2.0, 2.1, 3.0, 4.0 and other numbers. These numbers represent different versions and also represent the anti-interference ability of Bluetooth speakers. In 2012, 2.0 was common, 3.0 was the new mainstream, and 4.0 just launched. The Bluetooth version is different and is related to the received signal quality. The new version puts more emphasis on overcoming noise interference. The new version can be backward compatible, and consumers have to weigh the price and demand when buying.

4. Built-in battery

Domestic Bluetooth speakers have built-in batteries and are wireless. The quality of the built-in battery directly determines the playback time and service life of the Bluetooth digital speaker. Please ask carefully before buying the actual playing time and the number of repeated charging decay. It is recommended that consumers choose lithium polymer batteries as much as possible when choosing Bluetooth speakers, without the risk of explosion.

2. how to charge the domestic Bluetooth speaker

1, domestic Bluetooth speaker charging generally takes 2-3 hours. A fully charged Bluetooth speaker can be used for 9-10 hours.

2. Turn off the power when charging, one is better for the battery of the Bluetooth speaker, and the other is faster charging.

3. Generally speaking, the red light means that it is charging, and the green light means that it is fully charged. If the red light is always on (charging for more than 3-5 hours), it means that there is a problem with the charging circuit of your speaker, or there is no self-stop function after it is fully charged. If it can be used normally after 1 hour of charging, do not time out.

4. If the Bluetooth speaker uses a lithium battery, you must know that the lithium battery has almost no memory effect and can be used as it is charged, but the capacity may not be reached several times before. Generally, it is normal after 3 times of normal charging and discharging. Up.

5. There is a protection circuit inside the lithium battery, which can protect the battery from overcharge and overdischarge, and support high current charging and fast charging. You only need to charge until the green light is on to charge normally. If you charge too much, it is easy to damage the protection circuit.

In addition, know the nominal capacity of the Bluetooth audio battery, such as 700MAH. The general empirical value is that under the 200 mA fast charging current, the battery needs 1 hour of charging time every 100 mA, so the 700mA needs about 7 hours of charging time. By analogy, if it is a 1300MAH rechargeable battery, it takes 13 hours to fully charge.

7. do not use bluetooth speaker charging. If you must use it, it will cause some damage to the battery of the Bluetooth speaker. The damage value depends on the value of the Bluetooth speaker and your understanding of the appliance. Typically, the battery in the speaker is replaceable.
