Magnetic pogo pin connector for bone conduction Bluetooth headset

When it comes to Bluetooth headsets, everyone must be familiar with them, especially in recent years, the Bluetooth headset market is booming, 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 headphones, etc. Although pogo pins are used in all of these products, today we are going to introduce a small branch of Bluetooth headsets – bone conduction Bluetooth headsets, which are very popular among sports enthusiasts.

When it comes to bone conduction headphones, not many people may know it, so what are bone conduction headphones? Bone conduction earphones refer to earphones that use human bones as a medium to transmit sound to the auditory organ 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, bone labyrinth, inner ear lymph fluid, auger, auditory center, etc. The principle is shown in the following figure:

Magnetic Pogo pin connectors are commonly used in the charging interface of bone conduction earphones to charge the batteries in the earphones to ensure their normal operation.

Don’t underestimate these two small contacts, which contain cutting-edge technology. The human body will sweat a lot when exercising. When you wear headphones, it will inevitably cause a lot of sweat on the headphones. 98% of sweat is water, and the rest is inorganic salts, urea and uric acid.

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 electroplating layer on the contact will be slowly electrolyzed, even if it is more than the water. The acid substances in the electrolyzed fate sweat will slowly corrode the electroplating layer; and the surface electroplating layer plays a role in protecting the contacts and increasing the electrical conductivity. When the protective layer is damaged, it will lead to Poor contact during charging, so that the earphones may not be charged normally. Without electricity, the earphones will become waste products.

Therefore, the surface treatment of pogo pin connectors and contacts used on sports headphones should be at least anti-electrolysis and anti-corrosion, and on products that may come into contact with the skin, it should also be ensured that it will not cause skin allergies. This one has stumped a lot of companies. The unique surface coating technology independently developed by TopLink can pass the artificial sweat resistance test and salt spray resistance test for >240 hours, which can completely solve the above problems.
