[0031] See Figures 1 - 3 , the present invention provides a Bluetooth headset, including:

[0032] A detachable headphone main unit 1 and an extension unit 2. The headphone main unit 1 is provided with first connection contacts 13. The extension unit 2 includes a mounting position 21, and the mounting position 21 is provided with second connection contacts 212. When the headphone main unit 1 is installed in the mounting position 21, the first connection contacts 13 and the second connection contacts 212 are electrically connected to charge the headphone main unit 1 through the extension unit 2;

[0033] The extension unit 2 is of an ear-hanging structure. When used in combination, the headphone main unit 1 is located in the ear canal, and the extension unit 2 is hung behind the auricle.

[0034] In the above embodiment, the charging and communication functions can be realized through signal transmission. When it is needed to charge the headphone main unit 1, specifically, the electrical connection between the first connection contacts 13 and the second connection contacts 212 can be used to charge the headphone main unit 1; the extension unit 2 of the ear-hanging structure is hung on a person's ear, specifically, it can be hung on the auricle. At this time, the headphone main unit 1 is just located in the ear canal. In this way, the entire wireless Bluetooth headset can be hung on the ear through the extension unit 2 to realize charging while using, improving the battery life. And there is no need for a person to hold the extension unit 2. When not in use, the headphone main unit 1 can be directly installed on the mounting position 21 of the extension unit 2 for charging, without the need for an external power supply for charging, improving the charging convenience. When the first connection contacts 13 and the second connection contacts 212 are used for communication signal transmission, the headphone main unit 1 can obtain data through the headphone extension unit 2 and realize functions such as mobile calls, expanding the use functions of the wireless Bluetooth headset and optimizing the use experience of the wireless Bluetooth headset. This invention has the advantages of being able to independently realize the charging and communication functions, having a strong battery life, and being convenient for charging. It should be noted that the headphone main unit 1 here can be the wireless Bluetooth headset we usually use and can be used alone, that is, when charging is not required, it can also be connected to a mobile phone through Bluetooth alone to realize its functions.

[0035] In one embodiment, the mounting position 21 is formed with a hollow portion 211, and the second connection contacts 212 are arranged on the inner wall surface of the hollow portion 211, and the positions of the first connection contacts 13 and the second connection contacts 212 are correspondingly arranged. Those skilled in the art can understand that the headphone main unit 1 generally includes a headphone main body portion 11 and a headphone earplug portion 12 inserted into the ear. The first connection contacts 13 can be arranged on the side surface of the headphone main body portion 11. When the headphone main unit 1 is put in, the first connection contacts 13 and the second connection contacts 212 are in contact to achieve electrical connection. In this embodiment, the two charging contacts are arranged on the side surface, and it is not easy for dust to deposit on the contacts. And after electrical connection, the two contacts are separated by the housing of the mounting position 21 and the headphone main unit 1, not easy to get water in, and not easy to cause human ears to contact and get an electric shock.

[0036] Please refer to Figure 3, in one embodiment, the installation position 21 is further formed with a notch 213, and the notch 213 penetrates through a part of the side wall of the hollow portion 211 along the extending direction of the hollow portion 211. The structure of the hollow portion 211 of the extension machine 2 fits with the connection part of the earphone main body 1. The installation position 21 is made of a material with a certain elasticity. When the earphone main body 1 is put in, the earphone main body 1 is pushed into the hollow portion 211 of the installation position 21 of the extension machine 2 from the notch 213. When pushing, the notch 213 opens and undergoes a certain deformation. After pushing, the notch 212 recovers its deformation. That is, the earphone main body 1 can be pushed into and embedded in the installation position 21 of the extension machine 2 through the notch 213 of the extension machine 2, realizing the snap - fit fixation of the earphone main body 1. Additionally, it should be noted that the earphone main body 1 distinguishes between the left and right ears, and its structural design is symmetrical. However, the first connection contacts 13 of the left and right earphones and the structural design of the connection part with the earphone extension machine 2 are the same. The extension machine 2 does not distinguish between the left and right, and its structural design can be respectively adapted and assembled with the left and right earphone main bodies 1.

[0037] In one embodiment, a first magnetic member is provided in the earphone main body 1, and a second magnetic member is provided near the side wall of the hollow portion 211 in the extension machine 2. When the earphone main body 1 is installed in the installation position 21, the first magnetic member and the second magnetic member are close to each other, so as to tightly suck the earphone main body 1 on the installation position 21 through magnetic attraction. In order to further improve the connection stability between the earphone main body 1 and the extension machine 2 and prevent the earphone main body 1 from falling, the first magnetic member and the second magnetic member can be respectively provided, and the magnetic attraction between the two makes the earphone main body 1 and the extension machine 2 more tightly connected. This embodiment is an optional implementation manner based on the snap - fit through the notch 212 in the previous embodiment, which can further increase the installation stability of the earphone main body 1 and prevent the earphone main body 1 from falling.

[0038] In one embodiment, the extension machine 2 is made of a flexible material, and the bending angle and shape of the extension machine 2 can be adjusted. When using the Bluetooth earphone, the earphone main body 1 is placed in the ear canal, and the extension machine 2 is hung on the auricle. Since the sizes and shapes of the ears of different users are different, the extension machine 2 is made of a flexible material, so that the extension machine 2 can be adjusted in shape, arc and bending angle within a certain range, increasing the fit degree between the Bluetooth earphone and the user's ear, making the Bluetooth earphone not easy to fall, and improving the wearing stability of the Bluetooth earphone.

[0039] In one embodiment, the extension machine 2 further includes a clamping portion 22 connected to the installation position 21, and the shape of the clamping portion 22 is adapted to the shape of the auricle. Specifically, the installation position 21 can be designed to be adapted to the shape of the human external auditory canal, which is convenient for the earphone main body 1 to be placed in the ear canal; the clamping portion 22 is set to be an arc - shaped bending shape adapted to the human auricle, which is convenient for the extension machine 2 to be firmly hung on the ear.

[0040] Refer to Figure 4, in one embodiment, the extender 2 further includes a housing and a power management system 5 and an application system 4 which are electrically connected and disposed in the housing.

The power management system 5 is used to supply power to the application system 4 and can also be used to charge the headphone host 1. Through the network module, the networking function of the Bluetooth headset can be realized, and network signals, audio signals, etc. can be transmitted to the Bluetooth headset through the second connection contact 212. Through the application processor 27, rich networking application functions (such as listening to music) can be realized. It should be noted that in the prior art, users need to carry multimedia devices such as mobile phones when using Bluetooth headsets. In most cases, mobile phones are often carried by users. However, in some cases, such as running or walking, users want to listen to music but do not want to put a bulky mobile phone in their pockets.

[0041] In addition, after the networking function is realized, the Bluetooth headset can also be connected to the Internet of Things. Specifically, it can synchronously share the audio files uploaded in the user cloud server or obtain network audio files in real time. After receiving the network data, the application processor 27 can perform audio processing, and transmit the audio data to the headphone host 1 through the second connection contact 212 and the first connection contact 13, and data sharing and synchronous playback can be performed through the Bluetooth connection between the Bluetooth headsets. Specifically, the Bluetooth headset can be controlled to play the above audio files through physical buttons, physical touches, or voice assistants to realize the independent use function of the wireless Bluetooth headset without relying on multimedia devices such as mobile phones. This embodiment can get rid of the dependence of the Bluetooth headset on the mobile phone in the traditional technology, and the extender 22 is hung on the ear without the need for manual holding, which will not cause additional workload.

[0042] In one embodiment, the network module includes a WIFI module 23 and a user identification card module. The WIFI module 23 and the user identification card module are respectively connected to the application processor 27, and an identification card installation slot 223 is provided on the housing. The headphone extender 2 further includes a communication system 3. The communication system 3 is electrically connected to the power management system 5.

The user identification card module can be the commonly referred to SIM / eSIM module 24. eSIM is an embedded identification card module. When the user identification card module is a SIM card module, the SIM card can be installed in the identification card installation slot 223 of the housing. Of course, the network module can also include a GPS module 25. Specifically, the storage function or the Internet of Things sharing function or the data connection function of the memory card 26 of the headphone extender 2 can be used to save the contact information of common people or search for specific user contact information, and the physical button or physical touch or voice assistant can be used to control the connection or dial the phone, and the call is made through the audio device of the headphone main unit 1. In this way, the independent mobile call function of the headphone can be realized without a mobile phone, further expanding the function of the Bluetooth headphone.

[0043] In one embodiment, the headphone extender 2 can be built with necessary software functions and implement specific functions through the corresponding function modules of the built-in intelligent system, such as voice assistant service, map route query and guidance, time query and announcement, weather query and reminder, important schedule record and reminder, and application functions such as querying the receiving status of important information such as WeChat and emails on the mobile phone.

[0044] In one embodiment, the application system 4 further includes control buttons 222, indicator lights 221, and a charging interface 224 that are provided on the housing and connected to the application processor 27.
