Abstract

The invention discloses a multi-purpose full-frequency loudspeaker sound box. The multi-purpose full-frequency loudspeaker sound box comprises a full-frequency loudspeaker, a loudspeaker vibration cavity and a base sealing plate; the loudspeaker vibration cavity is provided with an upper end opening and a lower end opening; the full-frequency loudspeaker is arranged at the upper end opening; the base sealing plate is arranged at the lower end opening; the loudspeaker vibration cavity includes a contraction section and an expansion section; the inner diameter of the junction of the constriction section and the expansion section is the minimum inner diameter of the loudspeaker vibration cavity; the multi-purpose full-frequency loudspeaker sound box further comprises an acoustic wave refraction plate; and the acoustic wave refraction plate is obliquely arranged above the upper end opening. According to the loudspeaker vibration cavity, the Venturi tube effect is utilized so as to significantly enhance the volume feeling of ultra-low frequency, the descending depth of low frequency and reaction speed; the full-frequency loudspeaker, facing upwards, is mounted vertically on the top of the constriction-expansion tubular cavity with no panel adopted, so that the full-frequency loudspeaker can emit sound in a 360-degree diffusion manner and in the form of a point sound source; the increase of the width and depth of a sound field can be benefitted; the acoustic wave refraction plate horizontally guides part of acoustic waves emitted by the loudspeaker to a listener; and acoustic image positioning is more accurate and clear, and immersive experience can be enhanced.

Description

technical field

[0001] The invention relates to the field of audio processing and playback, in particular to a multi-purpose full-frequency speaker box. Background technique

[0002] In the prior art, the loudspeaker speakers of the home audio-visual entertainment system can basically be divided into two categories: one is a two-channel Hi-Fi stereo speaker, mainly for listening to music, and the users of this type of speaker are mostly music or audio equipment For audiophiles, they often have very strict requirements on sound quality. Because this kind of speakers mainly pursue high-fidelity and pleasant timbre in music expression, most of them are lacking in presence and low-frequency dynamic performance. Watching movies in home theater is often unsatisfactory; the other type is multi-channel AV home theater speakers. Because this kind of speakers are mainly for watching movies, they often cannot meet the requirements for high sound quality when listening to music. Demand...
