Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a magnetic earphone. Background Art

[0002] A Hall switch is a switch made of Hall elements. When a magnetic object moves close to the Hall switch, the Hall element on the switch detection surface produces the Hall effect, causing the internal circuit state of the switch to change, thereby identifying the presence of a magnetic object nearby and controlling the switch to turn on or off. As time goes by, Hall switches are also used in headphones.

[0003] Patent 201720621176.8 discloses an earphone, wherein when the Hall element 410 senses the attraction between the first pronunciation unit 10 and the second pronunciation unit 20, the first acceleration sensor 50 senses the motion state of the earphone. The patent sets magnets on the first pronunciation unit 10 and the second pronunciation unit 20 to make them automatically attract, such as setting two magnets 130 and 140 on the first pronunciation unit 10 and the second pronunciation unit 20, respectively, and the two magnets 130 and 140 are respectively set on the attraction part 160 of the first pronunciation unit 10 and the attraction part 160 of the second pronunciation unit 20. However, since the magnetism of the magnet will gradually disappear over time, the sensitivity of the Hall element is reduced, and according to the attached patent Figure 1 and 2 When the earphones are magnetically snapped together, the magnets (including 130 and 140) of the patent are at a certain distance from the Hall element 410. When the magnetism is weakened to the point where the distance cannot trigger the induction of the Hall element, the user can either manually bring the Hall element and the magnet closer to increase the sensitivity, or replace the magnet with a new one after a certain period of use.

[0006] The first magnetic attraction component is arranged in the first shell, and includes a first ring-shaped magnet and a Hall plate; the Hall plate is arranged in the inner ring of the first magnet, and the top of the Hall plate protrudes relative to the top surface of the first magnet in the first shell;

[0007] It also includes a first separator; a first separator is provided with an annular groove for accommodating the first magnet on a side facing the first shell cover; an inner wall of the first shell cover is in close contact with the Hall plate and the first magnet;

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0027] In the embodiment of the utility model, the Hall plate 32 is placed in the annular magnet to prevent the Hall plate 32 from being affected by the magnetic field of the annular magnet on the same side. When the magnet in the opposite earphone head approaches, the Hall plate 32 is triggered to output a signal. By designing the top of the Hall plate 32 to be higher and closer to the cover plate than the top surface of the first magnet 31, when the two earphone heads are attracted, the distance between the Hall plate 32 and the magnet in the opposite earphone head is closer, which can improve the sensitivity of the Hall plate 32.
