Introduction to Bluetooth speakers

A Bluetooth speaker refers to a sound device that is equipped with a built-in Bluetooth chip and uses Bluetooth connection instead of traditional cable connection. After being connected to Bluetooth playback devices such as mobile phones, it achieves the purpose of convenience and speed. At present, Bluetooth speakers are mainly portable speakers and micro desktop 2.0 and 2.1 speakers, with a generally small and portable appearance. Bluetooth speaker skills are gradually valued and accepted by customers due to their convenient and humanized characteristics.

The characteristics of Bluetooth speakers

1. Widely used. The Bluetooth skill standards are consistent, and many devices such as mobile phones, PDAs, wireless headphones, laptops, cars, devices, computer peripherals, etc. can easily connect to Bluetooth devices with Bluetooth adapters for data transmission or voice communication. It is widely popular and has good compatibility.

2. Simple operation. Bluetooth skill is an instant skill that does not require a fixed infrastructure and is easy to install and set up. It does not require cables to complete the connection, making it very convenient to use. It only requires simple pairing to be put into use, and the operating threshold is low.

3. The transmission speed is fast. Compared to other methods such as infrared, Bluetooth transmission protocol has significant advantages in speed. The theoretical speed of Bluetooth 4.0 reaches 24Mbps, and a faster speed can ensure higher sound quality, giving it enough capacity to carry music with higher bit rates.

4. Moderate transmission interval. The transmission interval of Bluetooth is generally within 10 meters, which is exactly the size of a room and can transmit data through walls, making it very suitable for home environments.

Although it has many advantages, due to the Bluetooth transmission protocol being the same as other 2.4G devices, which share signals in this frequency band, it is inevitable that signals may interfere with each other. In addition, Bluetooth protocol is not a free skill, and any manufacturer using this skill must pay a patent fee to the organization, which will also be reflected in the cost. In 2012, the price of Bluetooth audio devices was still higher than that of ordinary products.
