Strip-shaped loudspeaker box with mirror image type low-frequency radiators

Abstract

The invention relates to a strip-shaped loudspeaker box with mirror image type low-frequency radiators. A box body is in a long flat strip shape. Low-frequency radiator installation holes symmetrical in position are formed in the upper and lower surfaces of the right half part, in the long axis direction, of the box body respectively, and the two low-frequency radiators are correspondingly installed in the two upper and lower low-frequency radiator installation holes in a mirror symmetry mode. A mid-low-pitch loudspeaker installation hole is formed in the left half part, in the long axis direction, of the box body, a mid-low-pitch loudspeaker is installed in the mid-low-pitch loudspeaker installation hole, and the mid-low-sound loudspeaker radiates sounds towards the part over the box body. A high-pitch loudspeaker installation table is arranged on the front side face of the left end, in the long axis direction, of the box body, a high-pitch loudspeaker is installed on the high-pitch loudspeaker installation table, and the high-pitch loudspeaker radiates sounds towards the part right ahead of the box body. The strip-shaped loudspeaker box has the acoustic properties of being small in distortion, good in low frequency, capable of bearing high power and excellent in high-frequency performance; the transient stability of the loudspeaker box can be improved, and thus the loudspeaker box can achieve a good sound effect when radiating low-frequency sounds.

Description

Technical field [0001] The present invention involves a speaker speaker. Specifically, it is a mirror -type low -frequency radiation speaker suitable for audio and video equipment such as tablets and other audio and video equipment, which belongs to the technology field of electro -sound equipment. Background technique [0002] In existing technologies, speakers are applied to thin TVs such as OLED, ULED, generally use small -caliber and short -range speaker units with acoustic structure design of the open speaker, and use the settings to improve the low -frequency response characteristics.However, this speaker usually has sound defects such as sound staining, guidance tube resonance, wind noise, and inverted pipes to varying degrees.Although the passive radiator can avoid part of the defects, the frequency response curve is steep in the starting section, the transient stability is slightly weaker, the deadline frequency is high, and the total loss of QL value is large.

AI Technical Summary

Problems solved by technology

However, this kind of speaker usually has sound defects such as sound coloration, phase tube resonance, wind noise and internal high frequency sound reflected by the phase tube to varying degrees.

Although the use of passive radiators can avoid some defects, there are unfavorable characteristics such as the frequency response curve is steep at the beginning, the transient stability is slightly weak, the cutoff frequency is high, and the total loss Ql value is large.
