Thin double-cone phase inversion type loudspeaker box

Abstract

The invention relates to a thin double-cone phase inversion type loudspeaker box. A box body is mainly composed of a lower shell and an upper shell, wherein a high pitch unit installing hole, a low pitch unit installing hole and a lower shell phase inversion hole are formed in the lower shell, the high pitch unit installing hole and the low pitch unit installing hole are distributed along the long axis direction and are located in the left half portion of the lower shell, the high pitch unit installing hole is close to the left end of the lower shell, the lower shell phase inversion hole is arranged along the long axis direction and is located in the right half portion of the lower shell, and an opening of the lower shell phase inversion hole is located in the right end of the lower shell. A high pitch unit positioning groove, a low pitch unit positioning groove and an upper shell phase inversion hole are formed in the upper shell, wherein the lower shell and the upper shell constitute the box body. A high pitch loudspeaker unit is arranged in the high pitch unit installing hole and the high pitch unit positioning groove, and a subwoofer unit is arranged in the low pitch unit installing hole and the low pitch unit positioning groove. An inverter tube is formed by corresponding combination of the lower shell phase inversion hole and the upper shell phase inversion hole. The thin double-cone phase inversion type loudspeaker box is ingenious and reasonable in structure, and pretty good low frequency tone quality is achieved under the condition that the thin structure of the loudspeaker box is guaranteed.

Description

Technical field [0001] The present invention belongs to the field of electro -acoustic technology and involves a speaker speaker. Specifically, it is a thin dual -tone pelvic pelvic view speaker with a thin two -tone speaker unit and a high sound speaker unit. Background technique [0002] In the existing technology, the product thickness requirement of the speaker speaker applied to LED TV is within 10mm.Traditional speaker speakers are based on high -quality design. Generally, two speakers (one treble, a medium -sized speaker unit) are composed of two speakers.Thin LED electro -sound equipment.Therefore, seeking a thinner speaker speaker for LED TVs for LED TVs is thinner (within 10mm) and a better low -frequency sound quality. Invention content [0003] The purpose of the present invention is to overcome the deficiencies in existing technologies, providing a thin dual -sound basin inverted speaker speaker. The structure is clever and reasonable.The extension forms an inverted...
