A device for automatically returning to normal through magnetic force, a charging assembly for a charging earphone using the device, and a master-slave earphone

Abstract

The invention relates to the technical field of headsets and particularly relates to an automatic return device through utilization of magnetic force, a charging assembly for charging headsets employing the device, and master and slave headsets. According to the automatic return device through utilization of magnetic force, when an object A and an object B are close to each other and a to-be-aligned element a on the object A and the to-be-aligned element b on the object B are forwardly aligned with each other, magnet Q on the object B and the magnet on the object A are aligned and attracted with each other, even if the object A and the object B are skewed a little, the magnet on the object A and the object B enables to the object A and the object B to return to original positions, the connection stability between the object A and the object B is kept, and the to-be-aligned element a on the object A and the to-be-aligned element b on the object B are always aligned with each other. Thedevice is applied to the charging headsets and a charging box of the charging assembly for the charging headsets, and the charging headsets can be stably charged by the charging box. The device is applied to the headsets, so the master and slave headsets can be controlled to be automatically switched off when the master headset and the slave headset are close to each other.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a device for automatically returning to alignment through magnetic force, a charging assembly for a charging earphone using the device, and a master-slave earphone using the device. Background technique [0002] In recent years, smart earphones have developed rapidly, especially with the popularization of mobile smart devices, the demand for various wireless charging earphones and wireless control earphones has increased significantly. In terms of wireless charging earphones, now most of them design thimble contacts on the charging box and contact with the contacts on the charging earphones to charge. In order to ensure the stability of charging, it is necessary to add a fixed card position to fix the earphones during the charging process. However, the user needs to manually fix the headset to a suitable position, and the fixed card position may also shift during use, resulting...

In terms of wireless charging earphones, now most of them design thimble contacts on the charging box and contact with the contacts on the charging earphones to charge. In order to ensure the stability of charging, it is necessary to add a fixed card position to fix the earphones during the charging process. However, the user needs to manually fix the headset to a suitable position, and the fixed card position may also shift during use, resulting in interruption of charging

For wireless control earphones, the common function is to make the master earphone close to the slave earphone to interrupt music playback. In order to realize this function, mechanical structures such as hooks are usually set on the master earphone and the slave earphone respectively, or the master and slave are attracted by magnets. Headphones, but the above methods are easy to loosen or shift, making the connection between the master earphone and the slave earphone disconnected

Whether the charging earphone is interrupted during charging or the master-slave earphone is disconnected, it will bring trouble to the user.
