Description

Earphone charging case

The present disclosure relates to an earphone charging case, and more particularly, to an earphone charging case provided with a speaker.

Earphones are miniaturized speakers that are inserted into the ears so that the speaker's sound can be emitted directly into the user's ear. Because it has no work, it is widely used to listen to the sound of portable devices such as mobile phones and MP3 players.

Recently, Bluetooth (more specifically, Bluetooth Classic Audio) deviates from the traditional concept of earphones (headsets) that receive and play sound source signals from external systems (e.g., smartphones, wearable devices, PCs, etc.) connected by a wired cable. Wireless earphones (headsets) that receive and reproduce sound source signals wirelessly through a radio frequency (RF) communication channel such as A2DP protocol or Bluetooth Low Energy Audio have been widely used. In addition, there is an earphone case that can easily store wireless earphones and also provides a charging function.

However, since the Bluetooth earphone is designed and manufactured to emit sound directly into the user's ear, it is difficult for multiple users to listen to the sound source together.

Accordingly, in addition to the ability to easily store and charge the Bluetooth earphone, additionally, for a device including a function of the wireless speaker to receive (connected) playback information from the Bluetooth earphone so that multiple users can listen to a sound source together Demand can exist in the industry.

Prior art documents of the present disclosure are as follows.

In this case, the control unit 170 may recognize that at least one of the first earphone 210 and the second earphone 220 is received, based on whether the second signal is received.

The control unit 170 may control the sound output unit 160 to output a preset sound when it is not recognized that each of the first earphone 210 and the second earphone 220 is stored (S120, No). (S130). Here, the preset sound may be a sound informing the user that at least one of the first earphone 210 and the second earphone 220 is not received.

When it is recognized that each of the first earphone 210 and the second earphone 220 is received (S120, Yes), the control unit 170 transmits the first control signal so that the first earphone 210 is turned on. 132) and transmits the second control signal to the second earphone 220 through the data terminal 132 so that the second earphone 220 is turned off (S140 ). ).

When the first earphone 210 is turned on in step S140, the controller 170 may receive sound data from the first earphone 210 through the data terminal. Here, the acoustic data may be data received by the first earphone 210 from the external terminal through the wireless communication unit.

The above-described steps in FIG. 5 may be changed in order as necessary, and at least one or more steps may be omitted or added. In addition, the above-described steps are only embodiments of the present disclosure, and the scope of rights of the present disclosure is not limited thereto.

Descriptions of the presented embodiments are provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art of the present disclosure, and the general principles defined herein can be applied to other embodiments without departing from the scope of the present disclosure. Thus, the present disclosure should not be limited to the embodiments presented herein, but should be interpreted in the broadest scope consistent with the principles and novel features presented herein.

As described above, related contents are described in the best mode for carrying out the invention.
