In one or more embodiments of the present invention, the inverted conduit is U-shaped, and the inverted conduit has an inner opening that communicates with the cavity.

In one or more embodiments of the present invention, support ears are symmetrically disposed on both sides of the front cover and the rear cover, and the support ears form an arc-shaped groove.

In one or more embodiments of the present invention, a vibration damping rubber pad is disposed in the arc groove.

In one or more embodiments of the utility model, the accommodating built-in anti-vibration adjusting sponge pad.

In one or more embodiments of the present invention, the front cover provides a positioning cavity for the speaker assembly.

Compared with the background technology, the utility model has the following effects:

due to the adoption of the scheme, the novel LED lamp is simple and firm in structure, easy to manufacture and use, quick in assembly operation and low in production cost; the effective utilization of the phase inversion pipeline plays a role in low-frequency sound wave expansion, when the vibrating diaphragm of the woofer vibrates back and forth, the front and back air is respectively pushed to vibrate to generate sound, and if the air passage is not provided, the part of sound wave energy radiated towards the inside of the box is wasted; the energy is used for driving the air inside the inverter tube to vibrate and sound, so that the low-frequency range and the volume feeling are widened, and the total output efficiency of the loudspeaker box is increased. Therefore, the product has excellent performance in both technical and economic aspects.
