While exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thoroughly and completely understood, and will fully convey the scope of the present disclosure to those skilled in the art.

[0051] In the description of the present application, it should be explained that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "far", "near", "front", "back" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0052] In the description of the present application, it should be explained that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0053] The inventors found that the two ways of controlling the hearing aid in the prior art have certain disadvantages. On the one hand, the mode of operation through the keys equipped on the earphone of the hearing aid, when the user touches the keys to switch the mode, may accidentally change the acoustic settings of the hearing aid, resulting in the occurrence of whistling. This not only affects the user's experience, but also may further damage the user's hearing. On the other hand, the mode of remote control through the APP, for beginners, especially the elderly, has a high learning cost of the APP, and the user needs to spend more time and effort to learn and master the use method of the APP. This not only increases the difficulty of the user using the hearing aid, but also may make the user have a negative emotion towards the hearing aid, thereby reducing the popularity of the hearing aid to some extent.

[0054] In order to solve the above problems, the inventors have developed a charging box for a hearing aid and a hearing aid to improve the convenience of using the hearing aid and improve the user's experience and satisfaction.

[0055] Embodiment one

[0056] Referring toFigure 1 and Figure 2 The embodiment provides a charging box of a hearing aid, which comprises a shell 7, a mainboard 5, a button 11 and a touch screen 8.

The button 11 can realize convenient switching of the mode of the headset, for example, switching from a daily mode to a noise reduction mode or an enhancement mode and the like. The design enables the user to quickly change the mode setting of the headset without using the touch screen 8.

[0059] In this embodiment, the headphone mode can be switched in two ways: the user taps the corresponding mode switching command icon on the touchscreen 8 or presses button 11. The motherboard 5 can quickly sense and process these operations, and then send a mode switching command to the headphone. Both methods can achieve headphone mode switching. The user can quickly switch headphone modes using button 11. Compared to button 11, the touchscreen 8 can intuitively and in real-time understand the headphone status and working mode, and control the headphone. It can not only realize the mode switching function, but also display the headphone battery level in real time and perform operations such as volume control, greatly improving the convenience and operation confirmation, and effectively enhancing the user experience.

[0060] Compared to existing technologies, the charging case in this embodiment allows for convenient control of the earphones, eliminating the need for users to learn and master the app. Furthermore, compared to equipping the earphones with buttons, this embodiment avoids feedback issues caused by touch buttons and prevents ear canal pain and pressure caused by pressing earphone buttons, thus improving user experience and satisfaction. The touchscreen 8 and buttons 11 enhance user interactivity with the earphones. Users can check the earphone status and control it at any time via the touchscreen 8, reducing the learning curve and improving ease of use.

[0061] In one specific embodiment, see [reference] Figure 2 The inner cavity of the outer shell 7 houses a Bluetooth module (not shown in the figure), enabling the motherboard 5 to establish a stable wireless connection with the earphones and achieve bidirectional data transmission. This allows the earphones' status information to be displayed synchronously on the touchscreen 8. Users can control the earphones by tapping the command icons on the touchscreen 8, enabling communication and intelligent control functions for the charging case. The process of establishing a Bluetooth connection with the earphones can be as follows: the outer shell 7 scans for nearby BLE (Bluetooth Low Energy) devices. The earphones announce their presence via broadcast packets, and the outer shell 7 can then recognize the earphones. After the search is complete, the outer shell 7 selects the earphones to connect. After the BLE connection is established, the outer shell 7 requests the earphones' UUID (Universally Unique Identifier) ​​information to provide services and characteristics. This information is crucial for identifying and accessing specific services and data on the earphones.

[0062] After the motherboard 5 and the earphones connect via Bluetooth, the motherboard 5 exchanges data with the earphones by reading or writing features. Furthermore, the motherboard 5 can subscribe to notifications for certain features to receive real-time updates when the earphone status changes. The motherboard 5 synchronizes the earphone's status information (such as battery level, connection status, volume, etc.) to the touchscreen 8. Users can control the earphones by tapping command icons on the touchscreen 8, such as adjusting volume or switching modes. These operation commands are sent to the earphones via Bluetooth and take effect immediately. In this embodiment, the charging case establishes a stable wireless connection with the earphones through its built-in Bluetooth module, enabling bidirectional data transmission and intelligent control functions, thus improving user convenience and experience.

[0063] In one specific embodiment, see [reference] Figure 2 and Figure 3 The charging case includes an inner shell 4 and a cover 2.
