Application of pogopin magnetic connector in bone conduction earphones

When it comes to Bluetooth headsets, everyone must be familiar with them, especially in recent years, the Bluetooth headset market is in full swing, and major manufacturers are competing to launch their own brands of Bluetooth headsets. Bluetooth headsets can be divided into: ear-mounted (wired), neck-mounted (wired), TWS true wireless headsets, etc. Although pogo pins are used in these products, today we are going to introduce a small branch of Bluetooth headsets - bone conduction Bluetooth headsets, which are favored by sports enthusiasts.

How do bone conduction headphones make sound?
Bone conduction earphones refer to earphones that use human bones as the medium to transmit sound to the auditory organs without passing through the external auditory canal and eardrum. Its principle is to convert sound into different mechanical vibrations, and transmit sound waves through the human skull, bony labyrinth, inner ear lymph, spiral, auditory center, etc.

How to charge bone conduction earphones?
The pogopin magnetic connector is commonly used in the charging interface of bone conduction earphones to charge the battery in the earphones to ensure their normal operation. The charging contact of the earphone will conduct electricity when it encounters water (this voltage is very low and will not cause harm to the human body), so that the surface plating layer on the contact will be electrolyzed slowly, even if it is more than the water The acidic substances in the sweat will slowly corrode this layer of electroplating layer; while the surface electroplating layer plays the role of protecting contacts and increasing conductivity. When this protective layer is damaged, it will cause Poor contact during charging, so the earphones may not be able to be charged normally, and the earphones will become waste products if there is no electricity.

Therefore, the surface treatment of pogo pin magnetic connectors and contacts used on sports headphones must at least be anti-electrolytic and anti-corrosion, and on products that may come into contact with the skin, it must also ensure that they will not cause skin allergies .
