Description

Technical Field

[0001] The present invention relates to the technical field of electronic products, and in particular to a multifunctional TWS earphone box. Background Art

[0002] In recent years, with the rapid development of wireless audio technology, TWS earphones have gradually become a popular product in the audio market due to their convenience, high sound quality and stylish appearance. TWS earphones achieve true wireless connection by equipping the left and right earplugs with Bluetooth chips, bringing users an unprecedented free experience. However, with the intensification of market competition and the diversification of consumer demand, simple wireless audio transmission can no longer meet all the needs of users.

[0003] Traditional TWS earphone boxes mainly serve the functions of charging and storage, but with the advancement of technology, users' expectations for earphone boxes have far exceeded these basic functions. For example, users hope that earphone boxes can provide more intuitive power display, smarter charging management, and more interactive methods. In addition, with the popularization of IoT technology, users also hope that TWS earphone boxes can achieve seamless connection with other smart devices, thereby providing a more convenient life experience.

[0004] In order to meet these needs, some TWS earphone boxes with innovative functions have begun to appear on the market. However, these products often only focus on improving the functions of a certain aspect, but lack comprehensive design. For example, although some products are equipped with a touch screen, they do not make full use of this function to provide a richer user experience; although some products integrate Hall sensing technology, they do not combine it with other smart functions to achieve more intelligent management.

[0005] Therefore, it is necessary to develop a multifunctional TWS earphone box that can not only meet the basic charging and storage needs of users, but also provide users with a more convenient, intelligent and comprehensive use experience by integrating touch screens, Hall sensors and other intelligent functions. This multifunctional TWS earphone box will combine the latest electronic technology, Internet of Things technology and mobile communication technology to bring users unprecedented audio enjoyment and life convenience. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a multifunctional TWS earphone box, which solves the problems raised by the above background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multifunctional TWS earphone box, comprising: The earphone charging box has a battery compartment inside for installing a power source; The box cover is rotatably connected to the upper part of the earphone charging box through a metal hinge seat; The main circuit board is installed inside the earphone charging box and is electrically connected to the power supply; The Hall sensor is installed inside the earphone charging box to detect the placement status of the TWS earphones. At least one TWS headset is provided for placing in a preset position for charging or storage; The touch screen is installed in the screen mounting hole on the front of the earphone charging box and is used to display and control the earphone status.

[0008] Furthermore, the multifunctional TWS earphone box also includes an earphone seat, which is fixedly installed on the top of the earphone charging box, and the TWS earphone is placed inside the earphone seat.

[0009] Furthermore, the Hall sensing device is composed of an auxiliary circuit board, a Hall switch and a charging pole. The Hall switch and the charging pole are integrated on the surface of the auxiliary circuit board. A magnet is installed near the bottom of the TWS headset. The Hall switch can cooperate with the magnet to detect whether the TWS headset is placed in the headphone socket.

[0010] Furthermore, a transparent window is provided on the front of the earphone charging box, covering the outside of the touch screen. The transparent window is made of tempered glass or acrylic board to protect the touch screen and ensure that the user can clearly see the information on the screen.

[0011] Furthermore, a camera is installed on the top of the front of the main circuit board, and the back of the main circuit board is integrated with a loudspeaker, a microphone, a charging port, a SIM card slot and a memory card slot.

[0012] Furthermore, the position of the camera corresponds to the image capture reserved hole on the front of the earphone charging box; the position of the loudspeaker corresponds to the sound amplification hole; the position of the microphone corresponds to the sound pickup hole; and the position of the charging interface corresponds to the charging port.

[0013] Furthermore, a switch button is installed on one side of the top of the earphone charging box to start or shut down the system inside the earphone charging box.

[0014] Furthermore, when the user opens the lid and places the TWS earphones inside the earphone socket, the Hall sensing device senses the magnet of the TWS earphones and generates an electrical signal. The main circuit board recognizes that the earphones have been placed and starts the charging program, controlling the charging pole to contact and conduct electricity with the reserved female terminal of the TWS earphones to charge the earphones. The user can view the charging status, power level, and connection status of the earphones through the touch screen, and perform operations such as adjusting the volume, switching songs, and answering calls.

[0015] The present invention provides a multifunctional TWS earphone box. Compared with the prior art, it has the following beneficial effects: 1. Through the integrated touch screen, users can intuitively view the charging status, power level, connection status and other information of the headset without opening the box or relying on other devices. At the same time, the touch screen also supports a variety of operations, such as adjusting the volume, switching songs, answering calls, etc., which greatly improves the user's convenience and experience; 2. The introduction of the Hall sensor device enables the earphone box to automatically detect the placement status of the earphones and start or stop the charging process accordingly. This intelligent management method not only saves the user's operation time, but also effectively avoids damage to the earphone battery caused by forgetting to charge or overcharging; 3. In addition to the basic charging and storage functions, the earphone box of the present invention also integrates multiple functions such as camera, microphone, SIM card slot and memory card slot. The integration of these functions makes the earphone box not only an audio device, but also a portable intelligent terminal integrating communication, entertainment and storage.
