The four keys of Bluetooth loudspeakers are the mode switching key, previous key, next key, and play key.
- Bluetooth speaker mode switch key: General Bluetooth speaker has two modes, one is Bluetooth mode, and the other is TF card mode. Bluetooth mode, as the name suggests, is to use Bluetooth on our mobile phones to connect and play online. The TF card has downloaded the songs and played them in sequence. The two models have their own uses, but they are all for our service.
- Bluetooth speaker up and down keys:loud speakers are designed with up and down keys. The purpose of this design is to provide convenience for us. If we don't want to listen to this song or want to listen to the previous song, it will be very convenient with this key. In fact, it is not only Bluetooth speakers that play up and down songs, but also tape recorders in our grandparents' era have this function key.
- Bluetooth speaker playback key: this function key is available on speakers. After all, only with this function key can it be played. The biggest purpose of the speaker is to play, so this play key is also a power key of the speaker, which is equivalent to a switch. The play key on the speaker should be an important one among all the function keys.
The reason why the speaker is connected successfully but there is no sound may be that the volume of the device is set too low, which can be solved by turning up the volume; It may be that the computer audio source is selected incorrectly. Just re-select it.
Bluetooth speaker refers to the audio equipment with a built-in Bluetooth chip, which replaces the traditional wire connection with a Bluetooth connection, and is mainly connected with Bluetooth playback devices such as mobile phones, tablet computers, or notebooks. Bluetooth speakers are mainly portable speakers, which are generally small and portable. Most of the common Bluetooth speakers in the market are mono speakers, and some multi-channel speakers with excellent sound quality have also emerged. Bluetooth is a low-cost and high-capacity short-range wireless communication specification. A Bluetooth laptop is a laptop with Bluetooth wireless communication function. There is also a legend about Bluetooth. In the 10th century, the Nordic princes competed for hegemony, and the king of Denmark stepped forward. With his unremitting efforts, the bloody war was stopped, and all parties sat at the negotiating table. Through communication, the princes cleared up their past grievances and became friends. Because the king of Denmark loves eating blueberries so much that his teeth are dyed blue, he is called the king of Bluetooth, so Bluetooth has become a synonym for communication. A thousand years later, when the new wireless communication standard was introduced, people named it Bluetooth.
