Solid Pin 2 Point Pogo Pin

Solid pin 2 point contact Pin

Since Apple released the first generation of AirPods in September 2016, it has opened the era of wireless earphones, and TWS earphones have ushered in unprecedented development opportunities. There are various brands and models on the market, and the quality is also uneven. TWS sports earphones are a subdivision of TWS Bluetooth earphones, which are mainly used to meet the needs of sports enthusiasts when exercising. Compared with ordinary TWS earphones, TWS sports earphones generally have functions such as being waterproof and sweatproof.

TWS earphones generally have a charging compartment. When charging is required, you only need to put the earphones in the compartment and you can charge them at any time. As long as the charging compartment has electricity, you can replenish the earphones with electricity at any time. Attentive people may find that there are several metal points on the TWS headset, and there are several retractable contacts on the corresponding charging compartment. This is the pogo pin (spring pin) component to be introduced today. It acts as a connection and can conduct current or electrical signals.

What's so special about the contacts used on this? Not to mention, it is different from ordinary TWS headphones. The two most critical points are mentioned above: waterproof and sweatproof. Because of sports, you will sweat. At this time, wearing headphones will inevitably cause sweat on the headphones. These contacts are connected to the power supply. When there is water between the contacts, it will cause electrolysis. If these contacts (solid pin) ) surface coating does not have electrolysis resistance, so after a few times of use, the surface plating of the contacts will be gradually electrolyzed off, which will cause poor contact of the contacts, and may not be charged or fully charged.

Antenna Simulation

Simulation in CST Research and Design Phase - S11, Efficiency

The antenna return loss and radiation performance simulation are free, and the head + hand model performance simulation supports the analysis of environmental problems.

Simulation in CST research and design phase - overall analysis, head impact confirmation, radiation direction confirmation

During the design phase, the antenna performance, head effect, and radiation beam pattern can be verified through the antenna simulation evaluation; the radiation beam pattern cannot be freely changed but needs to be adjusted. Simulation can bring potential good effects when used by users and improve user satisfaction.
