AI Technical Summary

Technical Problem

Existing speakers are prone to resonance and coloration, affecting sound clarity and fidelity. Furthermore, their traditional structure results in bulky speakers with poor portability and design flexibility.

Method used

The speaker enclosure is connected to the surrounding walls with vibration damping ribs to disperse vibration energy, enhance the rigidity of the shell structure, reduce standing wave formation, and improve sound purity. The modular design enables intelligent coupling between the projector and the speaker, simplifying device connection and portability.

Benefits of technology

It effectively suppresses speaker resonance, improves sound clarity and fidelity, reduces low-frequency distortion, enhances the portability and adaptability of the device, reduces maintenance costs, and improves space utilization and reliability.

Abstract

According to the sound box, the multimedia equipment and the electronic device disclosed by the invention, the vibration reduction rib of the sound box is used as a structural reinforcing piece to connect the at least two peripheral walls of the main shell together, so that the propagation path of vibration in the shell is changed, the concentrated propagation of vibration energy in the shell is avoided, and the resonance of the shell at a specific frequency is effectively inhibited. And the vibration reduction ribs disperse and absorb vibration energy through the structural design, so that the formation of standing waves is effectively reduced, and the tone quality purity is improved. And the vibration reduction ribs are connected with the plurality of peripheral walls, so that the overall structural rigidity of the main shell is enhanced, shell deformation caused by vibration is reduced, and the acoustic stability of the sound box is improved. In a low-frequency band, the vibration energy is relatively large, and the shell without the vibration reduction rib is easy to distort due to a loose structure. And through structural optimization of the vibration reduction ribs, the deformation resistance of the shell is improved, low-frequency distortion can be effectively reduced, and the overall tone quality performance is improved.
