Problems solved by technology

[0002] In the traditional passive speaker, the passive radiator and the speaker are set separately. This kind of speaker structure causes the sound from the passive radiator and the speaker to be unable to surround the same center of the circle when the speaker emits sound, which makes the positioning of the sound very difficult. Not good, it greatly affects the sound quality; and the passive radiator is often designed to be exposed outside the sound cavity, which greatly weakens the bass effect and the layering of the sound quality

Embodiment Construction

[0019] An embodiment of a passive sound box of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] A passive sound box of the present invention comprises a sound cavity 1, a speaker positioned in the sound cavity and a passive radiator 4. The sound cavity 1 is formed by connecting a bass cavity and a full sound cavity end to end, and the speaker includes at least A woofer 2 and a plurality of full-tone speakers 3, the woofer 2 is positioned in the bass cavity, and the multiple full-tone speakers 3 are positioned in the full-tone cavity; the passive radiator 4 is positioned and set At the junction of the bass cavity and the full tone cavity, the passive radiator 4 is matched with the bass speaker 2 . Preferably, the passive radiator 4 and the woofer 2 can be designed as a coaxial structure, so that the sounds emitted by the passive radiator 4 and the woofer 2 can surround the same center of circle, greatly improving the ...

Abstract

The present application discloses a passive loudspeaker box, including a tone cavity, and a speaker and a passive radiator located and disposed in the tone cavity. The voice cavity is formed by a bass cavity and a whole tone cavity connected end to end, the speaker includes at least a bass speaker and a plurality of whole tone speakers, the bass speaker is located in the bass cavity, and the plurality of whole tone speakers is located and disposed in the whole tone cavity. In addition, the passive radiator is located and disposed at a junction between the bass cavity and the whole tone cavity, and the passive radiator matches the bass speaker. The present application not only enhances a bass effect, but also enhances a sense of depth of the tone quality through locating and disposing the passive radiator at the junction between the independently disposed bass cavity and whole tone voice cavity.

Description

technical field [0001] The invention relates to a sound box, in particular to a passive sound box. Background technique [0002] In traditional passive speakers, the passive radiator and the speaker are set separately. This kind of speaker structure causes the sound from the passive radiator and the speaker to be unable to surround the same center of the circle when the speaker emits sound, making the positioning of the sound very difficult. No, it greatly affects the sound quality; and the passive radiator is often designed to be exposed outside the sound cavity, which greatly weakens the bass effect and the layering of the sound quality. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a passive sound box with a simple and reasonable structure, which not only enhances the bass effect, but also enhances the layering of the sound quality. [0004] The technical scheme adopted by the present invention in or...
