The development history of Bluetooth headphones

Judging from the development history of Bluetooth headsets, the future development of Bluetooth headsets will also be improvements and enhancements in improving sound quality, battery life and sound delay. Of course, the implantation of smart AI in future headsets will become more and more common.

Advantages of portable LED lights

LED uses low-voltage DC power supply (AC can be rectified into DC), and the power supply voltage is between 6~24V, which varies from product to product. In short, it uses a DC power supply that is safer than a high-voltage power supply, and is especially suitable for homes and public places.

How the sound was invented？

In 1915, there was an American named E. S. Pridham put a telephone listener of the time on a horn that played record audio, and when the sound could be heard by a group of people celebrating Christmas in San Francisco, electroacoustics was born.

A large group of people at the ceremony produced a lot of professional sound research and development of the science of sound reinforcement engineering.

The research background of Bluetooth speakers and the significance of research

In short, there are no technical obstacles to the realization of an application model of Bluetooth technology-Bluetooth speakers. this topicAimed at the realization of audio transmission and playback of current affairs, on top of this, a more comprehensive discussion of the protocol specifications of Bluetooth communication technologyAnd the methods and steps of Bluetooth application development, and mastered the new technology of Bluetooth wireless access. And further for the futureIn-depth study of Bluetooth technology and development of Bluetooth products have laid a solid foundation.

How to solve the delay problem in speaker debugging?

Usually, the sound reinforcement of outdoor bluetooth speaker is often more than two or two sets of outdoor bluetooth speakers. Therefore, when there are outdoor bluetooth speakers in the third or fourth group or more, due to the different positions of the outdoor bluetooth speakers in each group, we need to combine the outdoor bluetooth speakers with auxiliary (side fill, front fill, and delay tower, etc.) with the main amplifier. While the delay difference between the sound boxes is compensated, whether the phase curve is the same is also a problem that we need to consider.
