Description

Bluetooth Speaker {BLUETOOTH SPEAKER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a Bluetooth speaker that is connected to another device using Bluetooth to reproduce sound.

Bluetooth refers to a short-range wireless technology standard for exchanging information between mobile devices such as mobile phones, notebooks, earphones, and headphones. It is used when low-power wireless connections are needed in very short distances, typically around 10 meters. For example, if you use a Bluetooth headset, you can listen to the music of your MP3 player in your pocket without the hassle of cables.

Conventionally, Bluetooth headsets have been used to connect a mobile phone with Bluetooth and make calls without using hands while driving.

Meanwhile, as smartphones and tablet PCs become popular, it becomes possible to enjoy movies and music using smartphones and tablet PCs regardless of the place. However, due to the limitations of microphones built into smartphones and tablet PCs, it was impossible to reproduce high-quality sound. To compensate for these drawbacks, a Bluetooth speaker connected to a smartphone or tablet PC with Bluetooth can be used.

However, even a miniaturized Bluetooth speaker has a disadvantage in that the portability is somewhat deteriorated.
