[Abstract] M2 is a purely hand-made wooden speaker, very fine workmanship and has a good sound quality.
Tencent Digital (Bob) Bluetooth Speakers Are Different and Positioning Is Different
Some focus on portability, but also added three defense features
Some use a larger drive unit, more suitable for home use
But honestly
Most black, engineering plastic speakers
It's always not so harmonious at home
Maybe people need a more sophisticated, more home-friendly high-quality Bluetooth speakers
For example M2
Maybe you think that M2 is not different from those big bluetooth speakers
But in fact, its entire manufacturing process and process determine its connotation.
Yes, M2 is pure wood and completely hand-built
It's like the difference between manual tailoring and clothing
The company hired carpenters with 30 years of carpenter experience to build M2
Oak wood
Every part is delicately sculpted and polished
This attitude of perfection makes it completely different from the mass production speakers.
Place M2 at home
It's like an excellent craft
Has played a crucial role in the entire family environment
Of course, the speaker's job is to play music
Must have superior sound quality
M2 naturally will not ignore this important part
It has built in two 8W active speaker units
Can achieve 60-20000Hz frequency range and 93dB signal to noise ratio
In addition, the unique sound transmission effect of the wooden body
Can achieve warm and solid sound effects
Very suitable for playing light music, pop music and classical music
Although positioning home play
But the M2 also has a built-in battery
12 hours of continuous playback at 80% volume
Can be moved flexibly without having to plug in the power at home
In addition M2 also has two color options, and caramel color limited edition
The minimum price is 169 US dollars (about 1160 yuan)
For users who are pursuing high quality lifestyles, it is a good choice

The main function of the Solar Charge Controller is to manage the charging and discharging process between the Solar Panel and the battery in the solar power generation system. Its main function is to protect the battery from overcharge and over-discharge damage, ensure battery charging efficiency, and stabilize the operation of the solar power generation system.
Main effect:
Charge control: The solar charge controller controls the charging process by monitoring the voltage and current generated by the solar panel to ensure that the battery is charged at the appropriate voltage and current to extend the battery life.
Overcharge protection: The solar charge controller can monitor the charging status of the battery, and when the battery is fully charged, it will automatically stop charging to avoid battery damage caused by overcharging.
Over-discharge protection: The solar charge controller can monitor the discharge state of the battery. When the battery power is lower than a certain level, it will automatically stop discharging to avoid battery damage caused by over-discharge.
Differences from other charge controllers:
The solar charge controller is a charge controller specially designed for solar power generation systems, the main differences are as follows:
Applicable Energy: The solar charge controller is suitable for solar power generation systems, mainly used to manage the charging and discharging process between solar panels and batteries. While other charge controllers may be suitable for different energy generation systems, such as wind energy, hydro energy, etc.
Charging characteristics: The solar charge controller is optimized for the characteristics of the solar panel, and can control the charging process according to the output power and voltage characteristics of the solar panel. Other charge controllers may be optimized for different types of energy generation characteristics.
Protection function: Solar charge controllers usually have overcharge protection and over-discharge protection functions to ensure the safe charging and discharging of batteries. Other charge controllers may have different protection functions, depending on the needs of the application scenario.
Overall, the main role of the solar charge controller is to manage the charging and discharging process in the solar power generation system, protect the battery from damage, and stabilize the system's operation. Compared with other charge controllers, it is optimized for the characteristics of solar power generation systems and has unique functions such as overcharge protection and over-discharge protection to meet the needs of solar power generation systems.
