We know that the sound-producing part of a #speaker is a speaker, but why use a #speaker instead of directly listening to the #speaker? The purpose of the #speaker is to prevent the sound wave signal from the front and back of the #speaker diaphragm. A loop is formed, so that only high-frequency and intermediate-frequency sounds with a small wavelength can be transmitted, and other sound signals are superimposed and cancelled out. The physical model of the #speaker is to open a hole in an infinite rigid baffle to install the #speaker, so as to ensure that the sound signal on the front and back of the #speaker will not form a loop, resulting in a sound wave loop. However, in actual use, the #speaker cannot be made infinite. Therefore, people use a baffle behind the #speaker to form a closed space to ensure the frontal transmission of sound waves.1.The USB and audio cables are 1.3 meters long, which can meet various conditions of use. 2.The rear volume knob is easy to use. 3.The non-slip foot pad at the bottom reduces vibration and avoids abrasion. 4.Our product single channel is 3W power,Single cabinet with dual channels, supplemented by bass diaphragm to accentuate the bass, the volume is large, and the bass is sufficient. 5.Environment-friendly MDF The whole box adopts E0 grade 4.5mm environment-friendly MDF
