The difference between WiFi speakers and good bluetooth speakers
First of all, we want to talk about the different working principles of WiFi speakers and good bluetooth speakers. The working principle of WiFi speakers is to connect the speakers to the external network through a wireless router, and then connect the speakers through mobile phones, tablets, computers and other devices. Some multimedia protocols push music to the speakers for playback. WiFi speakers have strong transmission capabilities and can be connected to multiple devices for playback at the same time.
The working principle of the good bluetooth speakers is to connect the Bluetooth chip built in the speaker to devices with Bluetooth playback such as mobile phones and tablets, and then play the resources on the connected device. The good bluetooth speakers has low power consumption and uses one-to-one transmission. In this way, it can effectively ensure its good privacy.
The difference in working principle between WiFi speaker and good bluetooth speakers is what we have introduced above. Let’s take a look at the difference between WiFi speaker and good bluetooth speakers, so that we can better understand WiFi speaker and learn more. Knowledge about wireless audio playback equipment.
The sound quality of infinite speakers has always been the most criticized place by many people. The main reason is that the transmission rate of wireless good bluetooth speakers is not high, which cannot meet the requirements for lossless music playback. In this regard, there is a gap between Bluetooth speakers and WiFi speakers. There is a big difference.
First, let’s take a look at the good bluetooth speakers. The transmission rate of Bluetooth speakers is generally below 24Mbps (Bluetooth 4.0), which simply cannot meet the requirements for transmitting high-quality music. This is why many of us have said that the sound quality of wireless speakers is not good. the reason.The transmission bandwidth of WiFi speakers can be guaranteed to be above 150Mbps, which greatly improves the transmission effect of lossless music and video. Many people have also experienced the true meaning of listening to HiFi wirelessly from WiFi speakers.
In addition to the different transmission quality, the cost of WiFi speakers and good bluetooth speakers are also different, and it is also unacceptable to many friends. The price of an ordinary good bluetooth speakers can be controlled at about 50 yuan, while most WiFi speakers on the market The prices are basically over 1,000 yuan. Why is this?
In fact, the main reason for this is that WiFi speakers need an external CPU to check the IP password address. Even if there is no CPU, another MCU (micro control unit) is needed to ensure the work, but do not need to consider this at all. One point, the CPU price of a WiFI speaker is basically more than $10, plus the cost of technology, it will not be surprising to sell one for 1,000 yuan. The overall technology of Bluetooth speakers is mature, and the cost is well controlled, so you can find cheap good bluetooth speakers on the market.
Let’s talk about the biggest difference between WiFi speakers and good bluetooth speakers, that is, the interconnection of multiple speakers, which is different from the one-to-one or one-to-two of good bluetooth speakers. WiFi speakers can realize the needs of multiple speakers interconnected to play alone or as a whole. . In other words, if you are using WiFi speakers, you can treat your mobile phone as a control terminal, and use APP to control WiFi speakers in different rooms to play different music.
The main reason why WiFI speakers can achieve this function is because WiFi speakers are under the same network. The mobile phone can see the playing tracks of each speaker through the APP, and can also add or delete different track lists for other speakers for centralized control. Use WiFi speakers to form a pair of 2.0 systems for playback. Different channels use different WiFi speakers for playback, and the playability is very high.
Different from the traditional point-to-point playback of good bluetooth speakers, WiFi speakers can achieve one-to-many playback, which is more suitable for playback in the home environment and meets the different playback and listening needs of users.
First, let’s take a look at the push method of the good bluetooth speakers. We can break it down into several steps to explain. First, we need to download the data to the mobile phone, then decode it through the mobile phone audio, and then convert the MP3 into a Bluetooth-encoded audio stream. Media, finally transfer the decoded sound file to the speaker, and passively play it through the speaker. This method is relatively rigid for music listening. Before listening, it needs to go through a silent pairing step, and it needs to be completely dependent on the mobile phone for playback. .
WiFi speaker push method:
Compared with good bluetooth speakers, the playback of WiFi speakers is more liberalized. First, the connection of sound files is transmitted to the WiFi speakers through the WiFi transmission protocol, and the WiFi speakers will actively download them, directly on the speakers. Decoding and playback, this transmission method has a faster transmission speed, and higher bandwidth WiFi speakers can transmit high-quality audio files more easily, and now many mainstream online music servers support WiFi transmission protocols, which makes users can Listening to a large amount of music online, the effect of listening is not comparable to that of Bluetooth speakers.
I believe that friends who have used good bluetooth speakers have encountered such troubles, that is, when listening to music, they suddenly want to watch a video. At this time, you can only turn off the music and then play the video. That is to say, you can only listen to music on your mobile phone. Listening to music, many other things related to sound can't be done, the audio of the mobile phone is output all the way.
But this trouble is not a problem for the WiFi speaker at all, because the WiFi speaker is a completely independent entity and does not occupy the audio channel of the phone. Even if you use the WiFi speaker to listen to music and use the phone to watch video There will be no mutual influence, which means you can play your favorite background music while watching the video, and it will sound more pleasant.
In addition, the transmission distance and wall penetration ability of WiFi speakers are better. I have already introduced them to my friends. In fact, the mobile phone is more like a remote control terminal among the WiFi speakers. After the speaker starts playing, it can be used separately from the phone. The speaker can be played according to the pre-set playlist, no matter where you go, it will not affect the work of the WiFi speaker, so as to achieve a truly unrestrained listening experience.
