Apple Airpods series is the main sales force in TWS headset market at present, which leads the development of the market in terms of design and structural configuration. In the battery direction, Apple AirPods 1 and the 2nd generation all adopted steel-case pin batteries, but AirPods Pro was replaced by steel-case button cell, which made the brand manufacturers in the market quickly follow up.
I love audio network and pay close attention to the development of TWS headset market. In recent years, I made a detailed report on the disassembly of nearly 300 products, from which I found that many brands also used button cell with steel shell as their own TWS headset power supply. This is a detailed analysis of the advantages and product use cases of steel shell button cell in TWS headphones ~
1.TWS What battery does the headset need?
TWS earphone is mainly composed of charging box and earphone. The charging box plays the role of storing and protecting headphones and charging headphones. Usually, the charging box uses a small-capacity soft polymer battery, which is small in overall size and easy to carry, and can store headphones anytime and anywhere. However, some headphones have large charging boxes with built-in 18650 batteries, which can support the function of mobile power supply.
Because the headphones are wirelessly connected, both headphones also need to use batteries to power the internal devices. The batteries carried in the earphone are divided into soft bag batteries and steel shell batteries according to types, and the soft bag batteries can be made into various shapes to fit the shape of the earphone; According to the shape of the earphone, the steel shell battery can be divided into steel shell needle shape and steel shell button shape. Among them, steel shell button battery is widely used, and steel shell pin battery is only used in a few products.
Second, the advantages of steel shell button cell
I love to disassemble and analyze hundreds of TWS headphones, and found that more and more headphones use button cell with steel shell as power supply. We interviewed many battery experts in the industry, and learned about the advantages and precautions of steel case button cell as TWS earphone battery, and shared them with you for study and research.
Valta:
The advantages of steel shell button cell include: high battery capacity density; The round button conforms to the shape of the earphone and provides as large a battery capacity as possible in a compact space; The shell is hard and not easy to damage; Convenient production and assembly of earphone; There is no expansion in charge and discharge, so the earphone size can be designed more accurately, and there is no need to reserve expansion space.
Billion weft lithium energy:
Steel shell bean battery has higher energy density, lower expansion rate and leakage rate, high dimensional consistency, high space utilization rate and fast charging speed, which makes the assembly process of TWS headphones simpler and more convenient, and gives TWS headphones consumers a safe, portable and long-lasting experience.
VDL sub-building:
At present, TWS earphone products are mainly divided into in-ear and semi-in-ear. In order to achieve a comfortable wearing experience, the appearance curve of headphones mostly presents an irregular circle similar to the auricle. Therefore, when the battery is to be put in, it needs to be adjusted according to the appearance to carry a larger battery capacity.
The button cell of the steel shell has regular volume, small deformation and small expansion space, and can be directly attached to the PCB, which effectively saves space size and can provide batteries with larger capacity.
Micro-electricity new energy:
For manufacturers, the button cell dimension of steel shell is consistent, and there is no need to deliberately reserve expansion space. When the product is assembled, the acoustic cavity can be evenly distributed in the center, which ensures the consistency of FR and ANC curves and the manufacturing yield is well guaranteed.
For consumers/users, the earphone products of button cell with steel shell will not swell during use, and the product performance will not change with time.
From the above, we can know that the biggest advantage of steel shell button cell is that the product consistency is good, and it will not expand during the charge and discharge cycle, and it is not necessary to reserve expansion space for the battery, so it can set a larger battery capacity; The hard steel shell of steel shell button battery can realize automatic assembly, and can also play a good role in protecting the battery during assembly, preventing the battery from being squeezed or scratched during assembly and affecting the service life of the battery.
Button battery with steel shell has many advantages, but it also has a significant disadvantage, that is, replacing aluminum-plastic film packaging with steel shell with higher mechanical strength is heavier and more expensive than soft bag battery.
Three. Summary of button cell TWS Headphones with Steel Shell on the Market at Present
I love Audio Network. This time, it * * summarizes 43 103 application cases of steel shell button cell under the brand 15. These 43 products vary in size, and the capacity is within the range of 30mAh- 108mAh. The product application case covers most TWS earphone brands on the market at present.
