It can be quickly identified without the need of data cable or audio cable connection. It is easy to operate and convenient to connect. What are the specifications of the Bluetooth speaker?


From the perspective of sound quality performance, the effective audio data volume of CD sound quality data (44.1KHz sampling rate, 16bit sampling precision) is about 1.4Mbit. To transmit CD sound quality music signal, the transmission rate can be realized only at 2Mbit per second. Bluetooth The "2.1+EDR" specification is sufficient. Moreover, since such products often follow the mature acoustic structure of the traditional speaker, the wireless sound is played after the integrated Bluetooth module, and the sound quality is comparable to that of the same level speaker product.


From the specification point of view, although the Bluetooth 3.0/4.0 standard has been proposed, the former is mainly reflected in the Bluetooth radio frequency modulation mode is in line with Wi-Fi, the latter is reflected in the application of automatic power control, that is, low power consumption, from this Both versions reflect the advancement of Bluetooth technology, but have little to do with audio applications. From the perspective of chip-level applications, it is suitable for version 3.0/4.0.

Bluetooth mainstream speakers use the A2DP stereo protocol, while devices such as smartphone tablets in 2
