This article explains the working principle of wireless charging of TWS headphones (electricity-generated magnetism/magnetic electricity-generated electricity) and the key points of structural design of problems that are easy to encounter. I believe that after reading it, the wireless charging of small white can be enlightened and suddenly enlightened.

TWS headset wireless charge type:

1. Electromagnetic induction (TWS application): The alternating current of a certain frequency of the primary coil uses electromagnetic induction to generate a certain current in the secondary coil clock, thereby transferring energy from the transmission end to the receiving end.
2. Magnetic resonance: Magnetic resonance charging is composed of an energy sending device and an energy receiving device. When the two devices are adjusted to the same frequency, or resonate at a specific frequency, they can exchange energy between each other
3. Electric field coupling: power is transmitted by using an induced electric field generated by coupling two groups of asymmetric dipoles in a vertical direction. The general charging module is composed of two asymmetric dipoles arranged in a vertical direction. This group of dipoles is composed of activated carbon electrodes and ground electrodes of the power supply part and the receiving part.
4. Radio waves: It mainly consists of a microwave transmitting device and a microwave receiving device, which can capture the radio wave energy bouncing back from the wall and maintain a stable DC voltage while adjusting with the load. This method only requires a transmitter installed on the wall plug, and a "mosquito" receiver that can be placed on any low-voltage product, TWS headset wireless charging-charging principle explanation and easy-to-encounter problems:
1. Wireless charging transmitting end: electromagnetism, receiving end: magnetism.
2. The working principle of wireless charging two coils is basically equivalent to the principle of transformer (compared with transformer, wireless charging has no iron core). It is a process of electricity generating magnetism and magnetism generating electricity (oscillation circuit or alternating circuit is required to take effect).
3. Wireless charging has low conversion efficiency due to magnetic leakage and other reasons.

What is the role of inductor coil in inductor enterprise products?

The common electromagnetic coil inductance coil, its creative advertising design is not vertical rotation, but a certain angle of the frame line. This type of electromagnetic coil is referred to as a honeycomb electromagnetic coil. In the case of a week of rotation, the frequency of repeated bending of the cable is usually called the gold bending level. It is characterized by small size, small distributed capacitance, large electromagnetic induction storage capacity, suitable for honeycomb winding. Cellular electromagnetic coil selection of cellular coil winding machine inductance coil, the greater the turning point, the smaller the distributed capacitance.

Why is there a magnetic sheet under the wireless charging coil?

The field of wireless charger industry is booming. Wireless charging technology has been applied to more and more industry fields. The wireless charger products in the market are dazzling and the quality is uneven. The wireless charging coil plays a vital role in the quality of the wireless charger. Everyone knows that in wireless charger products, an indispensable accessory is the magnetic sheet. The processing and assembly of the magnetic sheet is extremely important. It directly affects the performance and user experience of the overall wireless charger product. Naturally, as consumers, they may pay relatively little attention. This is an indispensable factor when purchasing wireless charger products. Today, let us learn about the role of the partition.

Dongguan Penghao Electronics Co., Ltd. was established.

Thanks to the joint efforts of the company, we have upgraded and registered from penghao electronics factory to dongguan penghao electronics co., ltd. thank all friends for their strong support to penghao. dongguan shijie penghao electronics factory has gone through several years and has been upgraded from dongguan shijie penghao electronics factory to dongguan penghao electronics co., ltd. since March 2015. I am glad that we still serve everyone with penghao!

ISO 9001:2008 certification

Peng Hao passed the British QA International Quality Management System Certification in August 2013 and obtained the ISO9001:2008 Certification Certificate. All the staff of the company have been trained, with stronger quality awareness and higher product quality.

Hand in hand SANYO

Thanks to the guidance of SANYO leaders, we continue to work hard, improve and better serve our customers. On March 07, 2012, Peng Hao joined SANYO's supplier system and officially held hands with SANYO successfully. Through six months of planning, examination and sample preparation, the voice coil produced by Penghao has been affirmed by SANYO, and Penghao's products have followed the SANYO brand to people's lives.
