Products Description
Mood Light Bluetooth Speakers for Home
The Bluetooth speaker comes with 64 million colors of lights, which will change and flicker with the speed of the music. When the volume of the Bluetooth device is at 80-90% of the total volume, the light will flicker at a high frequency with the speed of the music. When the volume of the Bluetooth device is at 70-80% of the total volume, the light will flicker at a low frequency with the speed of the music. When the volume of the Bluetooth device is below 70% of the total volume, all 64 million colors of lights will be automatically turned off, and the Bluetooth speaker system will automatically enter the hypnosis mode. At this time, the sound it plays is like a lullaby, giving people a comfortable rest environment. In addition, press and hold the power button for 3 seconds, and the Bluetooth speaker will enter the night light mode (i.e. warm white light lighting mode).

Detailed explanation of Bluetooth speaker microphone noise reduction function
In the field of modern communication and entertainment, Bluetooth speaker microphone combo devices have won the favor of a large number of users for their convenience and practicality. Among them, Bluetooth speaker microphones with noise reduction function are favored by many users who have high requirements for sound quality. This chapter will analyze the principles and characteristics of Bluetooth speaker microphone noise reduction technology in detail to help you better understand this advanced function.

1. Principle of noise reduction technology
Noise reduction technology mainly captures the surrounding environmental noise and then cancels these noises through opposite sound waves to achieve clear sound quality. In Bluetooth speaker microphone combo devices, noise reduction technology can effectively reduce background noise such as street noise and wind, making your calls and music enjoyment clearer.
2. Implementation methods of noise reduction technology
Currently, noise reduction technology is mainly divided into two implementation methods: digital signal processing (DSP) and echo cancellation technology.
2.1 Digital signal processing (DSP)
Digital signal processing is to analyze the frequency and waveform of environmental noise through algorithms, and then generate opposite sound waves to cancel noise. This method can effectively reduce noise in a wide frequency band and provide better noise reduction effect.
2.2 Echo cancellation technology
Echo cancellation technology mainly reduces noise by identifying and eliminating echoes. This method is suitable for eliminating echoes generated at the same time as human voices, such as in conference rooms or telephone conferences.
3. Advantages of noise reduction technology
3.1 Improve call quality
Bluetooth speaker microphones with noise reduction function can effectively reduce the interference of environmental noise, make your calls clearer, and improve communication efficiency.
3.2 Improve music experience
Noise reduction technology can greatly improve the sound quality of music playback, allowing you to enjoy pure sound effects in noisy environments.
3.3 Convenient outdoor use
In outdoor environments, the noise reduction function can effectively reduce wind noise, vehicle noise, etc., allowing you to maintain a good sound quality experience in any occasion.
4. Application of noise reduction technology in Bluetooth speaker microphones
There are many brands and models of Bluetooth speaker microphones on the market, and many of them have noise reduction functions. These devices not only have excellent performance in sound quality, but also improve the user experience through noise reduction technology.
4.1 High-end brands
Many high-end Bluetooth speaker microphone brands, such as Sony, JBL, etc., have launched devices with noise reduction function. These products have high standards in sound quality, noise reduction effect and design.
4.2 Mid-to-low-end brands
In the mid-to-low-end market, there are also some cost-effective Bluetooth speaker microphone combo devices with noise reduction function. These products provide good noise reduction effect while meeting basic needs.
5. Buying guide
When buying Bluetooth speaker microphones with noise reduction function, you need to consider the following aspects:
5.1 Noise reduction effect
The noise reduction effect of different devices is different. You need to choose the right product according to your needs.
5.2 Sound quality performance
In addition to noise reduction effect, sound quality is also an important indicator for measuring Bluetooth speaker microphones.
5.3 Price and cost-effectiveness
On the premise of meeting the needs, choose products with moderate prices and high cost-effectiveness.
5.4 Brand and after-sales service
Choose products from well-known brands and pay attention to the quality of their after-sales service.

6. Conclusion
With the continuous development of technology, the application of noise reduction technology in Bluetooth speaker microphones will be more extensive. Future Bluetooth speaker microphone combo devices will have better noise reduction effects, better sound quality and more convenient use experience. In major shopping malls such as Sam’s Club, you can find a wide variety of Bluetooth speaker microphone products to meet your various needs.
