Introduction to Bluetooth Speaker
Bluetooth speaker refers to the built-in Bluetooth chip, Bluetooth connection to replace the traditional wire connected audio equipment, and mobile phone tablet PCs and notebooks and other Bluetooth playback devices to achieve the purpose of convenience. At present, the Bluetooth Speaker to portable speakers, the shape is generally more compact and portable, Bluetooth speaker technology also by virtue of its convenient features of the consumer gradually attention and acceptance, the market common Bluetooth Speaker for the mono speaker (single speaker unit ), But also the emergence of a number of excellent sound quality multi-channel speakers (two or more speakers unit).
Bluetooth Speaker is the Bluetooth technology used in traditional digital and multimedia speakers, so that users can avoid annoying wires tied down, freely in a variety of ways to listen to music. Since the advent of Bluetooth Speaker, with the development of intelligent terminals by the mobile phone tablet and other users of the widespread concern. Bluetooth technology (Bluetooth) so that speakers become possible, all kinds of well-known brands have introduced a wide variety of appearance of the "Bluetooth Speaker", consumers spend about tens of dollars to more than 3,000 yuan price, you can let yourself own Super stylish and convenient Bluetooth Speaker.
Bluetooth headset products on the market more, while the Bluetooth Speaker are relatively small. The so-called Bluetooth Speaker, in fact, refers to rely on the Bluetooth transmission protocol as a carrier for data transmission of the speaker, because most of the mobile devices (mobile phones, notebooks, tablet PCs) are equipped with Bluetooth chips, no data cable or audio cable connection Quickly identified, easy to operate, easy to connect.
From the sound quality performance, CD sound quality data (44.1KHz sampling rate, 16bit sampling accuracy) of the effective audio data is about 1.4Mbit, to transmit CD quality music signal, the transmission rate can only be maintained at 2Mbit per second can be achieved, Bluetooth "2.1 + EDR" specification is sufficient. Moreover, because these products are often used in the traditional sound of the mature sound structure, in the integrated Bluetooth module to achieve wireless playback, the sound quality performance with the same level speaker products.
From the specifications point of view, although the Bluetooth 3.0 / 4.0 standard has been proposed, but the former is mainly reflected in the Bluetooth radio frequency modulation in line with the Wi-Fi line, which is reflected in the application of automatic power control, that is, low power consumption, from this Two versions reflect the progress of Bluetooth technology, but not with the audio application. From the chip-level applications, suitable for 3.0 / 4.0 version.
Bluetooth mainstream speakers are used A2DP stereo protocol, and 2012 smart phone Tablet PC and other devices are supported A2DP protocol, so the use of perspective, the Bluetooth speaker without any obstacles.
