Summary: | The utility model relates to a fully sealed all-frequency and high-fidelity sound box. The fully sealed all-frequency and high-fidelity sound box comprises a box body, a first passive loudspeaker, a second passive loudspeaker, a first active loudspeaker, and a second active loudspeaker. The box body has an inner cavity, and is equipped with loudspeaker holes. The first passive loudspeaker, the second passive loudspeaker, the first active loudspeaker and the second active loudspeaker are all arranged on the box body via fasteners, and are positioned in the loudspeaker holes in the box body. The first passive loudspeaker and the second passive loudspeaker are arranged in a coaxial manner and arranged back to back. The first active loudspeaker and the second active loudspeaker are positioned on two sides of the second passive loudspeaker, and the axis of the first active loudspeaker and the axis of the second active loudspeaker are parallel to the second passive loudspeaker. The inner cavity of the box body forms a fully sealed space after the loudspeaker holes of the box body are blocked by the first passive loudspeaker, the second passive loudspeaker, the first active loudspeaker and the second active loudspeaker. In this way, air can be compressed more tightly, and the active and passive loudspeakers can produce more powerful sound. |
