Description

Technical Field

[0001] This utility model relates to the field of headphones, and in particular to a portable mobile charging case and Bluetooth headphones with external audio connection. Background Technology

[0002] Currently, portable charging cases, as accessories for Bluetooth earphones, primarily function for charging and storage, and their adaptability to audio transmission scenarios is significantly insufficient. 1. Most existing charging cases only support wireless audio connection between Bluetooth headphones and devices such as mobile phones and tablets. When users need to use traditional wired audio devices (such as desktop computers, MP3 players, etc.), Bluetooth headphones cannot directly receive wired signals and require an adapter or replacement of wired headphones, which is cumbersome and has poor compatibility. 2. Some devices with wired audio input have audio cables that are exposed outside the charging case. This not only makes them difficult to store, but also requires manual switching of the headphone audio signal when the audio cable is connected to or not, which is inconvenient. They cannot achieve automatic switching between "wired input-wireless output" and "wireless input-wireless output", nor do they utilize the physical characteristics of the audio transmission cable to expand additional functions, thus limiting the overall practicality and convenience of the device.

[0003] Therefore, there is an urgent need for a portable mobile charging case and Bluetooth headset that can connect to external audio to solve the above problems. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a portable mobile charging case and Bluetooth headset with external audio connection.

The hatch is hinged to the hull and can close or open the first and second slots; The control panel is located inside the cabin; The battery is housed inside the compartment and electrically connected to the control board. The connector is located inside the cabin and is electrically connected to the control panel. One end of the audio transmission line is electrically connected to the control board, and the other end extends to the outside of the cabin. The control board can wirelessly transmit wired audio signals to the first and / or second headphones when the audio transmission cable is connected to an external audio source, or the control board can wirelessly transmit received wireless audio signals to the first and / or second headphones when the audio transmission cable is plugged into the connector.

[0006] As one of the preferred embodiments of this utility model, the cabin is provided with a detection component electrically connected to the control board, which is used to detect whether the first earphone is accommodated in the first slot and whether the second earphone is accommodated in the second slot.

The cabin 10 is provided with a first slot 11 and a second slot 12, which are used to accommodate the first earphone 61 and the second earphone 62, respectively. The hatch 20 is hinged to the hull 10 and can close or open the first slot 11 and the second slot 12; The control panel 30 is located inside the cabin 10; The battery 40 is located inside the cabin 10 and is electrically connected to the control board 30; The plug-in socket 51 is located inside the cabin 10 and is electrically connected to the control panel 30; One end of the audio transmission line 52 is electrically connected to the control board 30, and the other end extends to the outside of the cabin 10; When the audio transmission line 52 is connected to an external audio source, the control board 30 can wirelessly transmit wired audio signals to the first earphone 61 and / or the second earphone 62. Alternatively, when the audio transmission line 52 is plugged into the connector 51, the control board 30 can wirelessly transmit received wireless audio signals to the first earphone 61 and / or the second earphone 62.

[0020] Reference Figures 1-2 This is a schematic diagram of the portable charging case in its first state. In this state, the audio transmission line 52 is inserted into the connector 51, which will generate a first signal on the control board 30. At this time, the control board 30 can automatically transmit the wireless audio signal sent from the mobile phone or other device to the first earphone 61 and / or the second earphone 62 wirelessly. At the same time, since the audio transmission line 52 is inserted into the connector 51, it can form a loop structure, which can then be used as a lanyard. Users can hang the charging case around their neck, on a backpack, or other similar locations to prevent the charging case from being lost. (Refer to...) Figure 3 This is a schematic diagram of the mobile charging case in its second state. In this state, the audio transmission line 52 is pulled out from the connector 51, which will generate a second signal on the control board 30. When the audio transmission line 52 is plugged into an external device, such as a desktop computer or MP3 player, the control board 30 can automatically transmit the wired audio signal sent from the desktop computer, MP3 player, etc., wirelessly to the first earphone 61 and / or the second earphone 62. It should be noted that the wireless method described in this utility model refers to wireless Bluetooth transmission, which is existing technology and will not be described in detail here, nor should it be considered as a limitation of this utility model.
