From the perspective of acoustics and structure, the innovation points of this Bluetooth speaker can be sorted out as follows: acoustically, the design of "sound transmission through the built-in base duct of the speaker" is skillfully adopted. The speaker is hidden inside the base, and the sound transmission path is optimized by accurately guiding the sound wave with the aid of the duct. It can not only realize compact layout by using the base space, but also reduce the reflection and interference loss of sound inside the equipment, broaden audio coverage and strengthen stereo effect; Structurally, the horn and base are constructed with smooth curved surfaces, and the conduit naturally connects the two, making the overall shape simple and design-oriented. At the same time, the compact structure is convenient for portable placement in multiple scenes, realizing collaborative innovation of acoustic function and structural form, and achieving a balance between sound quality improvement and beauty and practicality in limited space.
