Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless earphone technology, specifically to a non-fall-out semi-in-ear earphone and its charging case. Background Technology
[0002] In the current headphone technology field, traditional semi-in-ear headphones often face the problem of being prone to falling out. Due to the lack of an effective fixing structure, the headphones are easily slipped out during exercise or daily activities due to head movement or external force, leading to interruption of use or the risk of loss. For example, the movement of the headphones while running can gradually loosen the fit and eventually cause them to fall out of the ear canal; during commuting, the headphones may fall out due to collisions with pockets or backpacks. This problem is particularly prominent in scenarios involving prolonged use, reducing user trust in the product and the overall user experience. On the other hand, since the charging port of the charging case is exposed, some clothing fibers, hair, or dust can enter the charging port during use. Due to the narrowness of the charging port, it is difficult to clean the inside, and over time, this accumulation can lead to poor contact during charging. In response to the above-mentioned problems, those skilled in the art propose a solution for preventing the headphones from falling out, including a semi-in-ear headphone and charging case.

[0015] To provide a clearer explanation and illustration of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are described below. The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principle of the embodiments of this disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of this disclosure. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.
[0016] Example 1: The anti-fall-out semi-in-ear earphone includes a pair of semi-in-ear earphones 2. A speaker 204 is fixed to the head section of the inner cavity of the earphone shell 201 of each semi-in-ear earphone 2, and a speaker cover 205 is fixed to the front port. A silicone inner ring 5 is fitted at the joint between the speaker cover 205 and the earphone shell 201. The inner surface of the silicone inner ring 5 covers the joint with its own elasticity, preventing moisture from entering the earphone. A silicone outer ring 7 is fixedly connected to the outer surface of the silicone inner ring 5, forming an annular chamber 6 between them. Several fine holes and multiple grooves are formed on the outer surface of the silicone outer ring 7. When the earphone is inserted into the ear, the change in ear canal pressure causes air to enter and exit the annular chamber 6 through the fine holes, causing the silicone outer ring 7 to expand. Simultaneously, the grooves increase friction, improving the earphone's stability in the ear. An earphone PCBA board 202 is fixed to the tail section of the inner cavity of the earphone shell 201, and a charging plug 203 is snapped into the rear port. An earphone battery 206 is also fixedly connected to the head section of the inner cavity. The matching charging case includes a charging case mechanism 1. A rubber plug 3 is inserted into the charging port at the bottom of the charging case lower cover 101. A rubber pull strip 4 is fixed to the outer surface of the rubber plug 3. The end of the rubber pull strip 4 away from the rubber plug 3 is fixedly connected to the outer surface of the charging case lower cover 101, so that the rubber plug 3 can be pulled out or inserted into the charging port when not charging, protecting the charging port from clothing fibers, dust, etc. entering. The charging case PCBA board 107 is fixed to the bottom of the inner cavity of the charging case lower cover 101, the lower inner liner 106 is fixed to the top, and the upper cover 104 is hinged to the top. The charging case battery 103 is fixed in the inner cavity. The lower inner liner 106 and the upper inner liner 105 of the charging case have placement slots for placing semi-in-ear earphones 2. Magnets are embedded in the inner side of the lower inner liner 106, and a magnet is fixed inside the semi-in-ear earphones 2, which are fixed by magnetic attraction. A charging port 102 is provided at the bottom inside the lower cover 101 of the charging case, which is compatible with the plug of the charging case PCBA board 107.
[0017] Example 2: Based on the above examples, some adjustments are made to the structure of the anti-fall-out semi-in-ear earphones and charging case. In the anti-fall-out semi-in-ear earphones, the connection method between the earphone back shell 201 and each component remains unchanged. The silicone inner ring 5 and silicone outer ring 7 are made of a more elastic material, allowing the annular chamber 6 to expand and contract more quickly when the ear canal pressure changes. The distribution of the pores is more uniform to better adapt to different ear canal shapes, further improving the anti-fall-out effect. Regarding the charging case, the lower cover 101 and upper cover 104 are made of a more robust plastic, increasing the durability of the charging case. The rubber plug 3 is designed to fit the charging port more closely, enhancing the protection of the charging port.
[0018] Based on the above-described preferred technical solution, the working principle of the technical solution is explained as follows: For the anti-drop-off semi-in-ear earphone 2, a speaker 204 is fixed in the head section of the earphone back shell 201, and a speaker cover 205 is fixed in the front port. A silicone inner ring 5 is fitted at the joint between the speaker cover 205 and the earphone back shell 201. The silicone inner ring 5 covers the joint with its own elasticity, which can effectively prevent moisture and other foreign objects from entering the earphone and protect the internal components of the earphone from damage. A silicone inner ring 5 is fixedly connected to a silicone outer ring 7, forming an annular chamber 6 between them. The outer surface of the silicone outer ring 7 has several fine holes and grooves. When the semi-in-ear earphone 2 is inserted into the ear, the pressure inside the ear canal changes. Air can then enter and exit the annular chamber 6 through the fine holes on the silicone outer ring 7, causing the silicone outer ring 7 to expand or contract with the change in ear canal pressure. Simultaneously, the grooves on the surface of the silicone outer ring 7 increase the friction with the ear canal skin. Through the combined effect of the elasticity of the silicone outer ring 7, the expansion of the annular chamber 6, and the friction of the grooves, the firmness of the semi-in-ear earphone 2 inside the ear is improved, solving the problem of semi-in-ear earphones easily falling out. The earphone PCBA board 202 is fixed to the inner end of the earphone shell 201. This is the control core of the earphone, responsible for processing various signals and control functions. A charging plug 203 is fixedly attached to the rear port for connecting the charging cable to charge the earphone. The earphone battery 206 is also fixedly connected to the inner end of the shell, providing power for the earphone's operation.
[0019] The charging case has a charging port at the bottom of the lower cover 101 of the charging case mechanism 1. When not charging, the rubber plug 3 is inserted into the charging port. One end of the rubber pull strip 4 fixed to the outer surface of the rubber plug 3 is connected to the outer surface of the lower cover 101, allowing the user to easily pull out or insert the rubber plug 3 into the charging port, protecting the charging port from clothing fibers, dust, etc., which may affect the charging function. The charging case PCBA board 107 is fixed at the bottom of the inner cavity of the lower cover 101. It is the control core of the charging case, responsible for managing the charging process and power display. The lower inner liner 106 is fixed above it. The upper cover 104 is hinged to the lower cover 101. The lower inner liner 106 and the upper inner liner 105 have placement slots for placing the semi-in-ear earphones 2. Magnets are embedded in the inner side of the lower inner liner 106, and magnets are fixed inside the semi-in-ear earphones 2. When the earphones are placed in the charging case, the magnetic attraction of the magnets firmly fixes the earphones in the placement slots. The charging case battery 103 is fixed in the inner cavity of the lower cover 101 of the charging case to provide power for charging the charging case and earphones. A charging port 102 adapted to the plug of the charging case PCBA board 107 is opened at the bottom inside the lower cover 101 of the charging case for connecting an external power source to charge the charging case battery 103.
