Air flow compression loudspeaker box

Abstract

The invention discloses an air flow compression loudspeaker box which comprises a loudspeaker box body, wherein two bass horns are symmetrically arranged in the loudspeaker box body. The air flow compression loudspeaker box further comprises a tweeter which is located between the two bass horns and is connected with a horn; the bass horns and the horn of the tweeter correspond to a sound outlet of the loudspeaker box body; the plane where sound holes of the horn are formed is flush with the front side of the loudspeaker box body; the plane where horn openings of the two bass horns are formed and the front side of the loudspeaker box body form included angles; the bass horns slantways face to the sound outlet of the loudspeaker box body and side plates of the loudspeaker box body; air outlets corresponding to the bass horns are formed in two sides of the sound outlet of the loudspeaker box body; the loudspeaker box body is of a bilateral symmetry structure; an upper side plate, a lower side plate and the side plates of the loudspeaker box body surround the bass horns; and an air flow compression cavity is formed at the horn opening of each bass horn. The loudspeaker box is more compact, reasonable and firm in structure and enables air flow to play a compression role in the loudspeaker box, so that the low-frequency sound effect and the impact force are effectively enhanced.

Description

technical field [0001] The invention relates to an airflow compression sound box. Background technique [0002] Ordinary symmetrically driven speakers are two woofers installed overlapping each other. When the speaker is working, the two speakers vibrate periodically, which strengthens the vibration of the air around the speaker, so that the same playback effect as the large-volume speaker can be obtained, and the bass is more powerful. However, this structure only simply uses the overlapping effect of the speakers, and does not effectively use the speakers to further enhance the sound effect. It is very inconvenient as the overall size of the loudspeaker increases sharply. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an airflow compression sound box, which can compress the airflow in the sound box, effectively enhance the low-frequency impact of the sound box, and have a more compact overall str...
