The decode plate 210 according to an embodiment of the present invention includes various sound control display units 211. Hereinafter, an embodiment of the sound output apparatus 100 according to an embodiment of the present invention will be described. I will explain.

First, the sound output apparatus 100 according to an exemplary embodiment of the present invention can be used by pairing with an electronic apparatus that can be paired by a short distance communication. The local communication at this time includes not only Bluetooth, Wi-Fi but also pairing by the NFC 220. When the deco plate 210 is pressed, power is supplied to the sound output apparatus 100 to change from the first state to the second state, and immediately enters the pairing mode. When the sound output apparatus 100 enters the pairing mode, the lighting member 235 blinks twice for 2 seconds to inform the user of the sound output apparatus 100. When the sound output apparatus 100 enters the pairing mode, If there is no device, the pairing mode is turned off. If there is a pairable electronic device in the vicinity of the audio output device 100, the audio output device 100 is created on the list that can be paired by Bluetooth on the electronic device, and a password is input to the electronic device And then perform the pairing with the sound output apparatus 100.

The pairing method is an easy pairing method when the power is turned on. When the electronic device is referred to as a first electronic device, when it is desired to pair the first electronic device with another second electronic device, There may be times when you want to pair an electronic device that has been paired before. At this time, the electronic device that has been previously paired may be the first electronic device.

In such cases, manual pairing must be performed manually. More specifically, when the decoupling plate 210 is pressed and the power is turned on, when the Bluetooth display unit 212 is touched for a predetermined time, the acoustic output apparatus 100 enters the pairing mode. At this time, when entering the pairing mode, it is blinked twice for 2 seconds as described above, and is outputted to the list of electronic devices which can be paired with the second electronic device or the electronic device which has been paired before. At this time, it is possible to perform the pairing by inputting the password to the second electronic device or the electronic device which has been previously paired. At this time, the step of inputting the password may be omitted in some cases.

Although the Bluetooth pairing mode has been described above, the same operation can also be performed in the case of pairing by Wi-Fi, so a detailed description will be omitted below.

In addition to pairing by Bluetooth or WiFi, pairing by NFC is possible. This will be described in more detail. First, when an electronic device capable of activating the NFC is brought into contact with the decoupling plate 210 of the sound output apparatus 100, the electronic apparatus recognizes the sound output apparatus 100 to be automatically paired, Quot; YES ", the audio output apparatus 100 is paired with another electronic apparatus. Once the audio output apparatus 100 is paired with another electronic apparatus by the NFC, if the electronic apparatus is located within a predetermined range from the audio output apparatus 100, the pairing is continued. If it is desired to close the pairing, the pairing may be blocked by bringing the electronic device closer to the decorating plate 210. [

Further, the sound output apparatus 100 according to an embodiment of the present invention can be connected to two electronic devices at the same time. 22 illustrates an example of use of an audio output device according to an embodiment of the present invention.
