Description

Technical Field

[0001] This utility model relates to the field of headphones, specifically to magnetic modular in-ear TWS headphones. Background Technology

[0002] In the current audio equipment market, in-ear TWS earbuds have gained popularity among consumers due to their convenience and excellent sound quality. However, as consumers' demands for personalized, maintainable, and upgradeable electronic products continue to increase, the structural design of traditional in-ear TWS earbuds is gradually becoming unable to meet these diverse needs.

[0003] Common in-ear TWS earbuds lack an effective modular design for connecting the head and stem shells. They typically use fixed clips or adhesive bonding. Clip-on connections are prone to wear and loosening after repeated insertion and removal, leading to unstable connections between the earbud head and stem, affecting normal use. Adhesive bonding makes disassembly nearly impossible for repairs or upgrades; forced disassembly often damages the earbud's structure, rendering it irreparable. Furthermore, current sealing cap designs often lack convenient magnetic inserts, resulting in a loose connection between the cap and stem shell, making them prone to detachment. Opening the cap to repair or replace internal components like the battery is cumbersome, requiring specialized tools and potentially damaging the earbuds due to improper handling. This increases user costs and reduces the earbuds' usability and lifespan. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a magnetic modular in-ear TWS earphone that can be quickly modularized and disassembled during use, thus solving the technical problem that existing technologies cannot easily remove the earphone for internal repair.

[0005] The objective of this utility model is achieved through the following means:

[0006] A magnetic modular in-ear TWS earphone includes a head shell, a stem shell attached to the mating surface of the head shell, a sealing cover installed at the bottom of the stem shell, a mating cover fitted at the opening of the head shell, a sound channel connected to the outside of the mating cover, a soft rubber sleeve fitted outside the sound channel, a battery inserted inside the stem shell, a magnet attached to the outer bottom end of the stem shell, an iron sheet laid on the inner wall of the sealing cover, a first spring contact connected to one side of the bottom end of the head shell, a second spring contact connected to the other side of the bottom end of the head shell, and a main control circuit board installed inside the head shell.

[0007] Furthermore, a buckle is provided circumferentially on the outer side of the opening of the head shell, and a slot is provided at the opening of the mating cover corresponding to the buckle, which facilitates the disassembly and assembly of the mating cover and improves the convenience of inspection and maintenance of the internal components of the head shell.

[0008] Furthermore, the top of the battery is equipped with pins, the inside of the sealing cover is fitted with contacts, and the outside of the sealing cover is equipped with anti-slip ridges. The anti-slip ridges prevent slippage when inserting the sealing cover.

[0009] Furthermore, a wire hole is provided on the lower inner side of the head shell, and the inside of the wire hole is connected to the inner cavity of the head shell. The first and second springs are both installed on the outside of the wire hole. The wire hole facilitates the connection of the wires of the internal components of the head shell to the battery.

[0010] Furthermore, the width of the second spring is smaller than the width of the first spring, and a groove is provided on the inner wall of the handle housing at a position corresponding to the second spring. The inner wall of the groove is flat, and the groove improves the tightness of the second spring insertion.

[0011] Furthermore, the length of the first and second spring pieces is half the length of the handle housing. A through hole is provided on the top side of the handle housing, and the top of the through hole penetrates the top end face of the handle housing. Through the through hole, when it is necessary to remove the head housing, a fine needle can be inserted through the through hole to squeeze the first spring piece, causing the head housing to lose some of its support force, thereby making it easy to pull out the head housing.

[0012] The beneficial effects of this invention are as follows: the magnetic block allows the sealing cap to be directly attached to and inserted into the stem shell, facilitating the repair and replacement of components such as batteries, effectively improving the maintainability of the headphones. Furthermore, the addition of the first and second springs allows for direct insertion and removal when assembling the head shell and stem shell, and provides a tight fit. This modular design allows for flexible assembly and disassembly of the head shell and stem shell. When a part of the headphones malfunctions or needs an upgrade, there is no need to replace the entire head shell; instead, the head shell can be pulled out directly during disassembly. The operation is simple and convenient, requiring no complex tools or professional skills, extending the lifespan of the headphones, reducing user replacement costs, and enhancing playability.
