The difference between bluetooth speaker and wifi speaker which is better
wifiSpeaker and bluetooth speaker are in Technical comparison
From a security point of view, the one-to-one transmission privacy of Bluetooth technology is better. WiFi is also easily interfered when there are many users, music synchronization is unstable, and packets are easily lost. Compared with Bluetooth technology, the data transmission rate of WiFi is higher. The 150M transmission bandwidth can fully meet the requirements of lossless music and high-definition video transmission. There is no waveform distortion and loss of details. The anti-interference is better. Higher audio CODEC, better audio specifications, and can pass through walls, so it is regarded as an ideal technology for high-quality wireless music playback.
Bluetooth technology is also showing a trend to move closer to WiFi technology. Bluetooth technology has been involved in IEEE 802.11 since Bluetooth 3.0, expecting high-speed data to follow the 802.11 specification and low-speed data to follow the Bluetooth channel. The latest generation of Bluetooth 4.0 technology has increased the data transmission rate to 24Mbps, and the transmission distance has also expanded to 60 meters, which is enough to meet the needs of lossless transmission. The Bluetooth 4.0 low-power version reduces power consumption by 90%.
In general, Bluetooth 4.0 audio equipment has lower power consumption, and its advantages are in the portable audio and video market, and will become a standard peripheral for smart terminals; while the advantages of WiFi technology are in networking solutions, home entertainment, engineering The audio system and high-quality cloud music are its strengths.
wifiComparison of the way of pushing music between speakers and Bluetooth speakers
The way of pushing music between Bluetooth speakers and WiFi speakers is very different. For example, if you use a Bluetooth speaker to play the music content of QQ Music, the first step is to download the data to the mobile client, the second step is to decode the mobile phone audio, and the third step is to transfer the decoded sound file to the Bluetooth speaker. The player is a passive player. If it is played through a WiFi speaker, through the WiFi transmission protocol, only the link of the sound file needs to be transmitted, and the WiFi speaker will actively download the music file, decode and play the music directly on the speaker side. This difference makes WiFi speakers more responsive when playing high-quality files that take up more bandwidth. And the current mainstream online cloud music services all support the WiFi transmission protocol.
Finally, WiFi speakers can be interconnected with other electronic devices that support WiFi in the home, one-to-many connection of several devices at the same time, and switching between devices is also very simple, unlike Bluetooth speakers that are cumbersome. pairing steps. If an operating system is added, the WiFi speaker can also independently select and play songs without relying on the mobile phone.
wifiComparison of the production cost of speakers and Bluetooth speakers
Compared with technology, the production cost is the current stage in the application of WiFi in speakers The biggest obstacle to replacing Bluetooth in the The WiFi speaker solution requires an external SOC chip (the cost is US$10, which is used to connect to the network); while the Bluetooth speaker does not require any external plug-in, and the overall cost is only 20 yuan. At present, Bluetooth speakers on the market can already be sold for 50 yuan per unit, while the price of WiFi speakers is still as high as 1,000 yuan.
wifiComparison of transmission quality between speakers and bluetooth speakers
First let’s look at traditional Bluetooth Speakers, whose bandwidth is generally below 24Mbps (Bluetooth 4.0), cannot meet the needs of transmitting high-quality music at all. This is also an important reason why many of us have said that the sound quality of wireless speakers is not good.
The basic bandwidth of the current WiFi speakers can be guaranteed to be above 150Mbps, and the transmission effect of lossless music and video has been greatly improved. Many people have also experienced wireless performance from WiFi speakers. Can listen to the true meaning of HiFi.
