DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] In the prior art, devices wearable on the human body, such as earphones for connecting with mobile phones, when the earphones are worn on the human body, adjusting the volume size needs to be realized through the volume adjustment key on the mobile phone or the earphones, and turning on or off the function of the earphones or switching the function of the earphones also needs to be realized through the on-off key and the scene switching key on the earphones. No matter turning on or off the function of the earphones or switching the function of the earphones, since the earphones are worn on the human body, the positions of the keys cannot be observed intuitively when operating, and the user can only determine the approximate positions and then operate in the approximate positions. This operation mode can cause the mis-touching situation.

[0033] Alternatively, wearable devices are hearing aids designed to improve hearing. Current hearing aid controls are primarily implemented through buttons on the device itself. Frequent and prolonged use and touching of the volume control and program switching buttons cause wear on the button surface coating, affecting button sensitivity and tactile feedback. Furthermore, prolonged use leads to aging of the internal mechanical structure of the buttons, resulting in poor button responsiveness or even complete failure. In addition, improper force applied by the user can damage the internal mechanical structure of the buttons. The button layout of some hearing aids may be unreasonable; for example, the volume and program buttons may be too close together. When manually pressing the buttons, the user needs to touch and operate them, making it difficult to locate the corresponding button immediately, leading to accidental presses or inaccurate operation. Moreover, when manually pressing the buttons, the hand may obstruct the hearing aid, causing feedback and creating a poor user experience.

[0034] Meanwhile, the presence of buttons, due to structural issues, reduces airtightness and isolation, affecting the hearing aid's waterproof and dustproof rating. When used in humid or extreme temperature environments, high humidity can cause moisture to seep into the buttons, allowing dust and dirt to penetrate. This affects the buttons' sensitivity and lifespan, ultimately impacting the hearing aid's normal operation. While remote-controlled peripherals exist for adjusting hearing aid functions, most are bulky, inconvenient to carry, or easily forgotten. Although mobile phones can be used for adjustment, their complex interfaces are often difficult for elderly or visually impaired users to understand, posing a challenge.

[0035] Alternatively, wearable devices include glasses, helmets, headbands, etc., worn on the human body and supported by the head. Glasses have functions such as translation, viewing, and communication, while helmets and headbands have functions such as information collection and video recording. Shoes, socks, or other products worn on the legs and supported by the feet have functions such as color, text, and image output. Devices worn on the arms or chest for monitoring and video recording also have the same problems as the aforementioned headphones or hearing aids.

[0036] In response to the above problems, refer to Figures 1-5This application provides an electronic device including a first wearable device 1, which can be worn on a first part of the human body. Depending on actual needs, the first part can be the location of wearable devices such as the ear, head, limbs, or chest. The first wearable device 1 can be an earphone or hearing aid worn on the ear, or glasses, helmets, or headbands worn on the head, or shoes, socks, or leg-shaping exercise equipment worn on the lower limbs, etc., used to assist the user in obtaining external information and changing output functions. Such devices have the problem of inconvenient operation during function adjustment. Furthermore, when the first wearable device 1 is an earphone or hearing aid, since there are usually two earphones or hearing aids, the second wearable device 2 needs to adjust the functions of all earphones or hearing aids during function adjustment. When there is only one earphone or hearing aid, the second wearable device 2 only needs to adjust the function of that one earphone or hearing aid. (Refer to...) Figure 1 When the first wearable device 1 is a hearing aid, the physical button structure on the outside of the existing hearing aid can be removed and the button structure can be placed on the second wearable device 2. With this setting of the first wearable device 1, the coating on the surface of the physical button on the hearing aid body can be avoided, and the waterproof and dustproof effect of the hearing aid body surface can be guaranteed, thereby improving the service life of the hearing aid. Moreover, the absence of external buttons makes the hearing aid more aesthetically pleasing. When viewed from the outside, the hearing aid is similar to headphones, making it less likely to attract the attention of others when the user is using it.

[0037] The second wearable device 2 is communicatively connected to the first wearable device 1. The second wearable device 2 can be worn on a second part of the human body, such as the arm (wrist, fingers, elbow, etc.), chest, abdomen, or legs. Wearing the second wearable device 2 in different positions meets the needs of different users. For example, when the second wearable device 2 is worn on the user's finger or wrist, the user does not need to carry it separately or place it in a pocket or storage item when not in use, making it easy to carry and less likely to be lost. When the second wearable device 2 is worn on the user's finger or wrist, adjusting the output function of the first wearable device 1 does not require the user to directly touch their ear or find a remote control-like peripheral device. The user only needs to operate the information input component 3 on the second wearable device 2 to adjust the first wearable device 1. This instant feedback and seamless operation greatly enhances the user experience, allowing users to fine-tune according to their needs anytime, anywhere, while fully considering user privacy and social comfort. In places such as public areas, even frequent adjustments to headphones, hearing aids, glasses, etc., will not attract unnecessary attention or misunderstanding from others. Furthermore, users can wear the second wearable device 2 as an accessory, which is less likely to attract the attention of others and less likely to be forgotten by the user.

[0038] In addition, when the first wearable device 1 is a hearing aid that helps improve hearing, the physical buttons or remote control of traditional hearing aids may be difficult to operate when the user is an elderly person or a person with hand movement disorders or other users with limited hand dexterity. The second wearable device 2 is worn on the human body with a simple and intuitive design, which greatly reduces the difficulty of operation. Users only need to complete various function adjustments through simple clicks, slides, rotations and other actions, which enhances the independent living ability of such users.

[0039] Reference Figure 1 The second wearable device 2 includes an information input component 3, which is used to input information. This input information is not limited to adjusting volume, switching audio playback on headphones, switching hearing aid usage scenarios, switching audio or video playback on glasses, or powering on / off. The input information is sent to the first wearable device 1, causing the first wearable device 1 to change its output function based on the received input. When inputting information using the information input component 3, the user can directly observe the component on the second wearable device 2 to avoid accidental touches. Alternatively, the user can operate the information input component 3 directly without observing it based on experience. Since the second wearable device 2 does not need to have many functions, it requires fewer components to implement the information input function. Therefore, the second wearable device 2 has a larger surface area for arranging the information input component 3, making its layout more reasonable and allowing for greater distance between different buttons, further preventing accidental touches.

[0040] Based on the above, the information input component 3 can input information in various ways, including but not limited to physical button input, touch input, and voice input. When the information input component 3 inputs information via buttons, some or all of the physical buttons on the first wearable device 1 used for adjustment functions are arranged on the second wearable device 2. These physical buttons may protrude from the surface of the second wearable device 2. In one embodiment, the physical buttons may be sliding buttons that slide along the surface of the second wearable device 2 to adjust the on / off function, buttons that can be pressed into the second wearable device 2 to switch scene functions, and knobs that adjust the volume by rotation. Alternatively, the button structure can be selected according to actual needs. The presence of physical buttons provides a better tactile experience when adjusting functions, and their use is simple and suitable for elderly users.

[0041] In addition to physical button input, the information input component 3 can also use touch input. That is, the surface of the second wearable device 2 is smooth, and a structure similar to touch buttons is provided on this surface, allowing users to input information by touch. Furthermore, simple markings can be placed on the smooth surface to clearly distinguish the functions of each location for easy identification. Touch input eliminates the need for protruding physical buttons on the second wearable device 2, resulting in improved overall waterproof and dustproof performance, and a more aesthetically pleasing design, making it suitable for use by young people.

[0042] Furthermore, in addition to the physical buttons and touch input methods mentioned above, a voice input structure can also be arranged on the second wearable device 2 to achieve different function adjustments using voice input. The voice input method can coexist with the physical button input method or the touch input method on the same second wearable device 2 for users to choose from. The voice input method is suitable for users with limited hand dexterity, such as children or the elderly who have difficulty operating.

[0043] In an optional embodiment, refer to Figure 2 , Figure 3 , Figure 4 The second wearable device 2 has a first surface 201 for contact with the human body, which is the surface that contacts the user's skin, a second surface 202 disposed adjacent to the first surface 201, and a third surface 203 disposed opposite to the first surface 201. The second surface 202 is disposed adjacent to the first surface 201, and the third surface 203 is disposed on the side opposite to the first surface 201. That is, the first surface 201, the second surface 202, and the third surface 203 cooperate to form the external structure of the second wearable device 2. The first surface 201 is the back of the second wearable device 2, the second surface 202 is the side of the second wearable device 2, and the third surface 203 is the front of the second wearable device 2. Since the second surface 202 and the third surface 203 do not directly contact the user's skin, the information input component 3 is disposed on the second surface 202 and / or the third surface 203.

[0044] In one specific embodiment, refer to Figure 2 The information input components 3 are all located on the second surface 202 of the side of the second wearable device 2. This structural arrangement makes the information input components 3 more concealed and less likely to attract the attention of others during operation. Alternatively, refer to... Figure 3 All information input components 3 are located on the front third surface 203 of the second wearable device 2. This structural arrangement makes it easier to visually observe the information input components 3 when inputting information, making them easier to operate and effectively preventing accidental touches. Alternatively, refer to... Figure 4Part of the structure of the information input component 3 is disposed on the second surface 202 on the side of the second wearable device 2, and the remaining part of the structure is disposed on the third surface 203 on the front of the second wearable device 2. With this structure, the distance between the various structures of the information input component 3 is large, which can effectively avoid accidental touch when inputting information by operating the information input component 3.

[0045] In an optional embodiment, the information input component 3 includes at least a selection key group for selecting from multiple options. The selection key group is used to select functions. By operating the selection key group, the user can select different functions according to their needs, thereby adjusting the functions of the first wearable device 1. In addition to the selection key group, the information input component 3 can also be equipped with a voice input and voice interaction function structure on the second wearable device 2 according to the user's actual needs. By utilizing the voice input and voice interaction functions, users with hand movement impairments can still input information and send commands to the first wearable device 1 without operating the selection key group, thus meeting the user's needs.

[0046] In an optional embodiment, refer to Figure 2 , Figure 3 , Figure 4 The selection key group has one or more of the following: a power button 4, a volume control button 5, and a scene switching button 6 for switching usage scenarios.

[0047] Users control the opening and closing of the first wearable device 1 by operating the power switch 4. When power switch 4 is a button or touch button and is set to one, clicking power switch 4 turns the first wearable device 1 on, and clicking power switch 4 again turns the first wearable device 1 off. This setting reduces the number of power switches 4 required. When power switch 4 is a button or touch button and is set to two, one button is the start button and the other is the stop button. This setting makes turning the first wearable device 1 on and off easier. When power switch 4 is a slider button, sliding power switch 4 in different directions turns the first wearable device 1 on and off. This setting further simplifies the operation of turning the first wearable device 1 on and off.

[0048] Users control the volume output of the first wearable device 1 by operating the volume adjustment key 5. When the volume adjustment key 5 is a button or touch button, there are two volume adjustment keys 5 on the second wearable device 2, one for increasing the output volume and the other for decreasing the output volume. This button or touch button design minimizes or eliminates the protrusion of the volume adjustment key 5 from the surface of the second wearable device 2, making the overall appearance of the second wearable device 2 more aesthetically pleasing. When the volume adjustment key 5 is a knob, there is one volume adjustment key 5 on the second wearable device 2. Rotating the volume adjustment key 5 in different directions increases or decreases the output volume. This knob design makes adjusting the output volume of the first wearable device 1 simpler and more convenient.

[0049] Users can adjust the functions of the first wearable device 1 using the scene switching button 6. When the first wearable device 1 is an earphone, the scene switching button 6 can be used to switch songs, etc. When the first wearable device 1 is a hearing aid, since each user's hearing needs and environment are unique, the second wearable device 2 can be customized. Whether in a noisy street, a quiet library, or a lively party, users can use the second wearable device 2 to adjust the first wearable device 1 according to the current environment, so that the first wearable device 1 switches to a suitable listening mode, ensuring that users can get the best listening experience in different scenarios.

[0050] In an optional embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 To further highlight and visualize the input information, allowing users to intuitively observe the working status of the first wearable device 1, a display screen 7 is also included on the second wearable device 2. The display screen 7 is communicatively connected to the information input component 3, and displays content based on the input information. When the user operates the second wearable device 2, they input information through different buttons, and the display screen displays the information accordingly. The displayed content is not limited to the on / off state of the first wearable device 1, the current scene mode, or the volume level of the first wearable device 1. Furthermore, the second wearable device 2 includes functions such as a clock; the display screen 7 allows the second wearable device 2 to display the time, increasing its functionality.

[0051] Furthermore, to enable information input in multiple locations or methods, or to reduce the number of buttons on the second wearable device 2, the display screen 7 is a touchscreen. The touchscreen is used for information input. By making the display screen 7 a touchscreen, it not only visualizes the input information but also serves as the user interface. When both the touchscreen display screen 7 and buttons are present, the user can choose either the touchscreen display screen 7 or the buttons to input information as needed. Even if one is damaged, the other can still be used for input. When only the touchscreen display screen 7 is present, it serves as both a viewing interface and an operating interface. The removal of buttons makes the second wearable device 2 more concise and aesthetically pleasing, simplifies its internal structure, and reduces operating costs. Specifically, when the display screen 7 is a touch e-ink screen, at least an information acquisition module, a display module, and a marking module need to be set in the second wearable device 2. The information acquisition module is used to collect input information from the touch e-ink screen and function keys. The display module displays relevant content on the touch e-ink screen based on the collected input information. The marking module marks target areas in the content displayed on the touch e-ink screen based on the information collected by the information acquisition module, ensuring that the display screen 7 has both input and display functions. The touch e-ink screen also has an information sending function to send input information to the first wearable device 1, enabling the first wearable device 1 to change its output function based on the input information.

[0052] In an optional embodiment, refer to Figure 5 The second wearable device 2 includes a housing 204. An information input component 3 and a display screen 7 are fixed to the surface of the housing 204. The interior of the housing has space to accommodate a battery 205 and a circuit board 206. It is understood that the first surface 201, the second surface 202, and the third surface 203 are assembled to form the housing 204. The housing 204 is preferably a rigid shell structure to support the information input component 3 and the display screen 7 when worn on the user's limbs, and to protect the battery 205 and circuit board 206 inside the housing 204. The battery 205 inside the housing 204 powers the various components, namely the display screen 7, touch buttons, voice input module, information conversion or transmission module, etc. A charging port is provided on the housing 204, which is electrically connected to the battery 205. The charging port is preferably located on the second surface 202 of the second wearable device 2, and a side-mounted charging port is more concealed.

[0053] In an optional embodiment, refer to Figure 5The first wearable device 1 or the second wearable device 2 also includes a controller 8, which is used to process information between the information input component 3 and the first wearable device 1. After the user inputs information using the information input component 3, the controller 8 converts and sends the input information to the first wearable device 1. The first wearable device 1 receives the input information and changes its output function according to the input information. Specifically, the controller 8 is located on the first wearable device 1. After the information input component 3 on the second wearable device 2 inputs information, it sends the input information to the controller 8 in the first wearable device 1. The controller 8 converts the input information and acts on different functional components within the first wearable device 1 to achieve function adjustment and switching. Alternatively, the controller 8 is located on the second wearable device 2. After the information input component 3 on the second wearable device 2 inputs information, the controller 8 converts the input information and sends the converted input information to different functional components within the first wearable device 1 to achieve function adjustment and switching.

[0054] In an optional embodiment, the controller 8 includes an information conversion module for converting the input information from the information input component 3, and an information sending or receiving module for sending the input information to the first wearable device 1, so that the first wearable device 1 changes its output function after receiving the input information. In a specific embodiment, the controller 8 is located within the first wearable device 1, and includes an information conversion module and an information receiving module. The information receiving module receives information sent by the second wearable device 2, and then the information conversion module converts the input information. In another specific embodiment, the controller 8 is located within the second wearable device 2, and includes an information conversion module and an information sending module. The information conversion module converts the input information, and then the information sending module sends the converted input information to the first wearable device 1.

[0055] In one specific implementation, the information transmission between the first wearable device 1 and the second wearable device 2 employs Near Field Communication (NFC) technology. NFC is a short-range, high-frequency radio technology that allows for contactless, point-to-point data transmission between electronic devices. This technology evolved from contactless Radio Frequency Identification (RFID) technology, and its foundation lies in RFID and interconnection technologies. NFC technology combines an inductive card reader, inductive card, and point-to-point functionality on a single chip, enabling identification and data exchange with compatible devices over short distances.

[0056] Specifically, Infrared Remote Control (IRDA) technology and proprietary Bluetooth protocols are both effective methods for achieving short-range wireless communication. Infrared remote control technology utilizes infrared light for data transmission, offering advantages such as low cost and no wiring required. It involves an infrared transmitter integrated into a second wearable device 2 and an infrared receiver installed on a first wearable device 1. An infrared remote control protocol is defined, including data encoding methods, transmission rates, and command formats. Software for the infrared remote control receiver is developed to parse the received infrared signals and execute corresponding operations. Bluetooth is a short-range wireless communication technology widely used for data transmission between various electronic devices. A proprietary Bluetooth protocol refers to a Bluetooth communication protocol customized based on the standard Bluetooth protocol to meet specific needs. Compared to infrared remote control technology, Bluetooth remote control offers advantages such as longer transmission distance and stronger anti-interference capabilities. A proprietary Bluetooth protocol involves a Bluetooth transmitter integrated into the second wearable device 2 and a Bluetooth receiver installed on the first wearable device 1. The proprietary Bluetooth protocol is customized according to requirements, including data transmission formats, communication rates, and encryption methods. Software for the Bluetooth remote control receiver is developed to process Bluetooth signals and execute corresponding operations. Simultaneously, software is also needed on the transmitter to send control commands.

[0057] In an optional embodiment, the second wearable device 2 is one of a bracelet, watch, ring, or necklace. (See reference...) Figures 1-4 The second wearable device 2 is a bracelet worn on the user's wrist. It features a power button 4, volume control buttons 5, scene switching buttons 6, and a display screen 7, which displays the time. The bracelet's casing 204 is designed for aesthetic appeal. The bracelet not only controls the first wearable device 1 but also serves a decorative function. Similarly, when the second wearable device 2 is a watch or ring, it also controls the output of the first wearable device 1 and serves a decorative function. Users can choose different appearances according to their needs. When a ring is chosen as the control device, considering its relatively small size, the display screen 7 is removed, leaving only the power button 4, volume control buttons 5, and scene switching buttons 6. This makes the ring less likely to attract attention and ensures a large distance between the buttons, reducing the chance of accidental touches.

[0058] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
