The Transmission Distance Of The Bluetooth Speaker Is Also A Matter Of Concern To Us

  The transmission distance of the Bluetooth speaker is also a matter of concern to us. The transmission distance of the Bluetooth speaker is independent of the Bluetooth version, which depends on the advanced level of the technology. The standard transmission distance of the PowerClass2 is 10 m, while the upgraded POWERCLASS1 increases the transmission distance to 100 meters and provides a fi stereo effect. Generally speaking, the handset and the Bluetooth speaker's distance is not too far, compares the insurance transmission distance to be approximately 10 meters. Market Bluetooth speakers are up to 10 meters standard.

  Version

  Consumer procurement of Bluetooth speakers, often see Bluetooth 1.1, 1.2, 2.0, 2.1, 3.0, 4.0 and other numbers, these numbers represent the version of the different, but also represents the Bluetooth speaker anti-interference ability. In 2012, the 2.0 most common, 3.0 new mainstream, and 4.0 had just been introduced shortly. The Bluetooth version is different from the quality of the receiving signal. The new version emphasizes the ability to overcome clutter interference. The new version can be backward-compatible, consumers should be measured when purchasing prices and demand.

  Built-in battery

  Bluetooth digital speakers are built-in batteries, so that the real wireless. The built-in battery good and bad directly determines the Bluetooth digital speaker playback time and service life. Please ask carefully for the actual playback time and the number of times of repeated recharge before purchasing. It is recommended that consumers choose the polymer lithium-ion battery when Bluetooth Bluetooth speaker is chosen, without explosion risk.

  Battery type:

  1 Polymer Battery:

  Advantages: safe and efficient, soft package without explosion hidden danger.

  Disadvantages: Kind of heteropoly, pure cobalt (good) and pure manganese (difference) polymer battery difference several times.

  2) 18650 Battery

  Advantages: Excellent performance, charge and discharge can reach the highest level (more for notebook batteries), there is explosion protection

  Disadvantages: more battery and old battery. Same 18650 battery good and bad difference 5-10 times

  3 Aluminum Shell Battery

  Advantages: The price is very cheap

  Disadvantage: poor performance. There is no explosion-proof measures, the consequences of the explosion unimaginable.

  Battery Protection Board:

  1 The Battery Protection Board of a motley battery is poor in charging and discharging protection.

  2 The unstable current output not only affects the sound quality, but also causes a great current sound.

  Good quality battery charge and discharge 500 times can also reach the initial capacity of 80%. The quality of the battery charge and discharge 100 times after the initial capacity of not even up to 50%.
