Bluetooth speakers and WIFI speaker which good
from a security perspective, bluetooth transmission privacy better one-on-one. WiFi under the condition of the users more easily also be interference, music synchronization is not stable, easy to lost package. If the technology advantage, will solve the wireless audio for bandwidth, power consumption and the way of connection problems. Compared with bluetooth, WiFi data rate higher, 150 m transmission bandwidth can completely meet the demand of nondestructive music, hd video transmission, there is no waveform distortion and break off both ends of the details of the loss, anti-jamming is better, can match the quality higher audio CODEC, get better audio index, and can wear wall, therefore is regarded as an ideal technology for the high quality wireless music and video.
of course, the WiFi is not perfect. From a security perspective, bluetooth transmission privacy better one-on-one. WiFi under the condition of the users more easily also be interference, music synchronization is not stable, easy to lost package. If the technology advantage, will solve the wireless audio for bandwidth, power consumption and the way of connection problems.
meanwhile, bluetooth appear to WiFi trend. Bluetooth technology from bluetooth 3. 0 IEEE 802. 11, looking for high speed data walk 802. 11 specification, low speed data of bluetooth channel. The latest generation bluetooth 4. 0 technology has been to increase the data rate to 24 megabits per second, the transmission distance is also expanded to 60 meters, enough to meet the needs of the lossless transmission. Bluetooth 4. 0 low-power versions is the power consumption was reduced by 90%. Overall, the bluetooth 4. 0 audio equipment lower power consumption, the advantages in portable portable audio market, will become the intelligent terminal standard peripherals. While the advantage of the WiFi in network plan, home entertainment, audio engineering system, high quality cloud music is the swimmer.
2 cost is
compared with the technology, cost is the present stage of WiFi in the applications of amp instead of bluetooth biggest obstacles. WiFi speaker solutions need a CPU (plugin Cost $12 ~ 14, password used to check the IP address) Or at least a MCU; And bluetooth speakers without any plug-ins, the overall cost as long as 20 yuan. Bluetooth speaker is currently on the market can sell for 50 RMB/set, and WiFi speaker price remains as high as one thousand yuan.
3 push more
bluetooth speakers and WiFi speaker music push. If, for example, with bluetooth speakers QQ music music content, the first step need to download the data to the mobile phone client, the second step mobile audio decoding, the third step to decode the voice file transfer to bluetooth speakers, which is passive players. If it is WiFi speakers, WiFi transfer protocol, only needs to transmit sound file link, WiFi speakers will take the initiative to download music files, directly in the sound box decoding and playing music. This difference makes WiFi speaker in broadcast bandwidth more high quality files, faster response speed. And now the mainstream online cloud music services support WiFi transport protocol. Moreover, WiFi speaker and home other support WiFi devices to realize interconnection and interflow, one-to-many connection several devices at the same time, the device switch between also is very simple, not as pairing bluetooth speakers have a cumbersome steps. If increased the operating system, WiFi speaker can independently choose songs and singing in operation, do not need to rely on mobile phones.
