DETAILED DESCRIPTION

[0036] The embodiment of the present invention provides a function expansion device for solving the technical problem that existing smart glasses are usually of non-detachable design, which limits the upgrading and replacement of modules and requires the purchase of new products. At the same time, there are few choices of glasses styles and they cannot meet the personalized needs of users.

[0037] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 , Figure 1 A schematic diagram of the structure of a function expansion device provided in an embodiment of the present invention.

[0039] A function expansion device provided by the present invention comprises a first function component having a power supply module, wherein the first function component is connected to a device to be expanded;

[0040] The first functional component has a main control chip and a first audio output component built in, and is used to synthesize corresponding stereo audio and output it via the first audio output component when the main control chip receives audio data.

[0041] The device to be expanded refers to a device that can be connected to at least the first functional component 1, including but not limited to the existing frame 3, strap 6, etc. Through the connection of the first functional component 1, it has AI characteristics, and is matched with the software ecosystem in the functional component to meet the scalable application requirements.

[0042] In this embodiment, by connecting the first functional component to the device to be expanded and powering it through a separate power supply module, the functional expansion flexibility of the device to be expanded is effectively improved. In addition, the first functional component has a main control chip and a first audio output component built in. When the main control chip receives audio data, the audio data is processed to synthesize stereo audio, which is played and output through the first audio output component. Compared with mono audio transmitted from one sound source, stereo audio usually has two channels. Through the difference in sound between the left and right channels, including volume, sound arrival time and other factors, the brain can construct an image of the position of the sound in space.

[0043] Optionally, the device to be expanded is a strap 6, and the free ends of the strap 6 are respectively provided with buckles;

[0044] Both ends of the shell of the first functional component are provided with slots matching the buckle, which are used for buckle connection with the strap 6.

[0045] In this embodiment, connecting slots may be provided at both ends of the housing of the first functional component, and buckles are provided at the two free ends of the strap 6, and the buckles are engaged with the slots to form a buckle connection, thereby fixing the first functional component on the strap 6. At the same time, when the user wears the strap 6, it is tightened by the pressure of the head, so that the position of the first functional component is further fixed.

[0046] The shell of the first functional component can also be made of materials with certain deformation properties such as silicone to meet the needs of different users. Or the shape of the shell of the first functional component can be made according to the head size of the user to meet the needs of user customization.

[0047] Optionally, the device to be expanded is a closed bandage, and the closed bandage includes a hardened part and a flexible part connected to each other;

[0048] The first functional component is embedded in the hardened part through a groove on the shell.

[0049] In this embodiment, the device to be expanded can also be a closed strap without free ends, and the closed strap is provided with a hardened part and a flexible part connected to each other. The hardened part is made of hardened material, and its length and shape match the size and shape of the first functional component. The flexible part is connected to both ends of the hardened part, which is convenient for users to wear and improves the comfort of users. When engaged, the groove on the shell of the first functional component is engaged with the hardened part to form a stable structure.

[0050] In addition, in a specific implementation, flexible materials such as straps 6 and headbands without free ends can also be fastened to the flexible material through the groove 4. Since the inner side of the groove 4 is filled with filling material and when the headband is worn, the headband will be tightened by the pressure of the user's head, so that the functional components can be firmly fixed.

[0051] Optionally, the function expansion device further includes a second functional component having a power supply module;

[0052] The second functional component is connected to the device to be expanded;

The second functional component 2 is equipped with a second audio output component 22, which can be used to cooperate with the first audio output component 13 to output stereo audio in the left channel and the right channel respectively.

[0056] The stereo audio can also be combined with the reverberation effect to realize the stereo audio output of a single audio output component.

Through this integrated circuit, an initial connection is established with an audio source device (such as a mobile phone) to manage Bluetooth pairing and communication protocols. It receives stereo signals from an audio source, which may be encoded digital audio, such as AAC or aptX format, and decodes, converts, reverberates, and processes the received audio signals to generate stereo audio.

The charging method for the first rechargeable battery 14 in the first functional component 1 is similar and will not be repeated here. The power supply module 25 can have a battery management function to realize the functions of charge and discharge control and a power meter. Specifically, the main control chip 11 and the auxiliary chip 21 can be combined with a machine learning model to record and learn the user's charging habits.
