Home theater, wireless speaker and wired sound box, which is good after all?
It must be wireless. I changed the family of PHILPS Fidelio series, wireless Bluetooth speakers, two rear speakers can change the position as needed, this design is great
Wired sound box is better than wireless sound box.Although the wireless communication technology is also very advanced, but want good sound effect, still need to use wire for transmission. The fidelity of the voice occupies a large bandwidth, the use of the current wireless can not meet the use of requirements, there will be delays and other issues.If you don't have much requirement for sound quality, consider wireless.
Wireless audio technology:Is the principle of wireless technology, the current strength of the conductor change will produce radio waves. The use of this phenomenon through the modulation information can be loaded on the radio, as the waves propagate through space at the receiving end, the sound waves caused by the variation of the electromagnetic field inside, will be generated in the conductor. The information is extracted through demodulation from the current changes in the sound level, tone processing into power amplifier driver stage and sound.Features of wireless audio products:2.4G wireless digital signal transmission, 30 frequency automatic matching, can be used for 30 classrooms simultaneously. The so-called 2.4G wireless technology, its frequency range is between 2.405GHz-2.485GHz. So referred to as 2.4G wireless technology. This frequency band is the international standard free frequency band, and there is no need to pay any fees to the international organizations concerned.Advantages of wireless audio products:2.4G wireless technology is different from the previous 27MHz wireless technology. It works in full duplex mode, and has an absolute advantage over 27MHz in anti-interference performance. This advantage determines its superior anti-interference, and the maximum transmission distance of up to 10 meters. In addition, 2.4G wireless technology also has a theoretical data transmission rate of 2M, doubling the transmission rate of 1M theory over bluetooth.Wireless audio facelift SL 228 is arranged on the top of lion music a handle, which is a collection of many before the customer opinion, although slightly larger than the portable speakers, but this is very convenient but portable design. The use of wooden boxes, frosted high-grade paint, thickening of the epidermis, the front thickness of 2.5 cm, playing strong music will not resonate, which is also a feature of it
Good sound signal transmission medium of high quality, is generally used to connect the audio signal line, wireless audio signal will be affected by the environment, will cause the sound signal loss to the distortion and delay. Of course, even if the signal line does not guarantee the loss of the signal, it can only be said that the higher the signal line, the less the loss of the signal. If you want to experience high quality audio and video enjoyment, you have to choose a wired audio system. But if you want to consider family decoration and the convenience of use, it is better to choose wireless. PHILPS E5 series uses "on-demand surround" technology, wireless rear surround speakers and the host computer using SMSC 5.8GHz wireless audio transmission technology, wireless transmission interference, only a very low voice delay, the use effect is still good.
Usually choose cable. Not wireless is not good, but it is new technology, after all, there is no cable technology so mature, products are relatively small. However, if you want to take care of the home style, it is recommended to choose wireless, and now 2.4G wireless technology has solved the problem of sound quality loss, the signal is also very good.
