What are the specifications of the Bluetooth speaker

What are the specifications of the Bluetooth speaker

There are many Bluetooth headset products on the market, while Bluetooth speakers are relatively few. The so-called Bluetooth speaker, in fact, refers to rely on the Bluetooth transmission protocol as a carrier for data transmission speakers, because most of the mobile devices (mobile phones, laptops, tablets) are equipped with Bluetooth chip, do not need data line or audio line connection can be quickly identified, simple operation, convenient connection. Judging from the sound quality performance, the effective audio data amount of CD sound quality data (44.1KHz sampling rate and 16bit sampling accuracy) is about 1.4Mbit. To transmit CD sound quality music signals, the transmission rate only needs to be kept at 2Mbi.

Bluetooth speaker purchase

Bluetooth speaker purchase

Although the compatibility of Bluetooth speakers basically supports existing Bluetooth devices, it is still necessary to check whether your playback device supports Bluetooth before buying it. The transmission distance of the Bluetooth speaker is also a problem that everyone is more concerned about. The transmission distance of the Bluetooth speaker has nothing to do with the Bluetooth version, and mainly depends on the advanced level of technology. The standard transmission distance of the PowerClass2 is 10 meters; the upgraded PowerClass1 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 is not too far, and the transmission is relatively safe.

Two Operation Schemes of Digital Audio Signal Compression Technology

Two Operation Schemes of Digital Audio Signal Compression Technology

After the audio signal is digitally encoded, one of the problems facing is the problem of mass data storage and transmission. Digital audio signal compression technology is a very important part of digital television broadcasting system. Compression efficiency and compression quality directly affect the transmission efficiency of digital television broadcasting and the transmission quality of audio and video. In this paper, the digital audio compression technology to do a shallow analysis. Compared with analog signals, digital signals have obvious advantages, but digital signals also have their own corresponding disadvantages, that is, the demand for storage capacity and the increase of channel capacity requirements during transmission. Audio compression technology refers to the original digital audio signal.
