Sound box based on oppositely buckled passive radiator

Abstract

The invention relates to a sound box based on an oppositely buckled passive radiator. The sound box comprises a prolate box body, a high pitch loudspeaker mounting hole and a mid-bass loudspeaker mounting hole distributed along the length direction of the box body are opened in the top of the box body, a high pitch loudspeaker unit is mounted in the high pitch loudspeaker mounting hole, and a mid-bass loudspeaker unit is mounted in the mid-bass loudspeaker mounting hole; a passive radiator unit is mounted on the right side of the mid-bass loudspeaker unit through a radiator bracket, and the central axial line of the passive radiator unit is mutually parallel to the central axial lines of the high pitch loudspeaker unit and the mid-bass loudspeaker unit; the radiator bracket is provided with two sound outlets which are symmetrically arranged at 180 degrees, the two sound outlets respectively face to front and back side faces of the box body, and sound outlet holes communicated with the sound outlets are respectively formed in the front and back side faces of the box body. The sound box provided by the invention both has the advantages of the passive radiator sound box and can perfect the defects of poor vertical transient stability, high cut-off frequency and large total loss Ql value, so as to ensure a good sound effect for the sound box.

Description

technical field [0001] The invention relates to a loudspeaker sound box, in particular to a thin sound box based on a buckle-type passive radiator suitable for use on audio-visual entertainment equipment such as a flat-panel TV set and a notebook computer, and belongs to the field of electroacoustic technology. Background technique [0002] In the prior art, speakers used in OLED TVs and ultra-thin notebook computers can only use small-diameter, short-stroke speaker units to radiate sound due to the thinning and miniaturization of the structure, resulting in low-frequency differences in the entire sound system. , the sound pressure is low; as an improvement, the structure of the open speaker is usually adopted, and the low-frequency response characteristics are improved by setting the inverter tube, but it will bring the sound coloration in the inverter tube, resonance of the phase tube, wind noise and reflection of the inverter tube Various sound defects such as internal hi...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a thin sound box based on the buckle-type passive radiator, which has an ingenious structure, compact and reasonable, not only has the advantages of the passive radiator sound box, but also can improve passive radiation The disadvantages of speaker speakers, such as weak vertical transient stability, high cut-off frequency, and large total loss Ql value, enable the speaker to achieve good sound effects when radiating sound, especially low-frequency sound
