Display device built-in passive sound box

Abstract

The invention discloses a display device built-in passive sound box and a displayer, and relates to a sound box device. The display device built-in passive sound box can reduce the volume of the sound box and improve low-frequency effect. A miniature enclosed loudspeaker is characterized by comprising a sound box, a loudspeaker single unit, a first passive radiation part and a second passive radiation part, wherein the loudspeaker single unit is arranged in the sound box, and a diaphragm of the loudspeaker single unit is positioned on a first surface of the sound box; the first passive radiation part is arranged on the first surface; the second passive radiation part is arranged on the second surface of the sound box; the second surface is opposite to the first surface; and the first passive radiation part and the second passive radiation part can buffer sound pressure generated by loudspeaker parts in the sound box. The invention discloses the displayer provided with the built-in passive sound box. The display device built-in passive sound box and the displayer are suitable for the field of sound box manufacture.

Description

technical field [0001] The invention relates to a sound box device, in particular to a miniature airtight speaker structure. Background technique [0002] A horn or loudspeaker consists of a mechanical structure in which a compressed fluid (i.e., air) acts as the damping medium for an enclosure. The speaker unit or the speaker unit is a complex of mass, elasticity and damping. When the speaker unit vibrates, it produces sound waves. The principle is to generate vibration by the elasticity of its suspension system. If the speaker unit is installed in the speaker, because there is air in the speaker, and the air itself has mass, when the speaker unit generates sound pressure and compresses the air in the speaker, it is as if the air travels in the speaker in a state of pressure waves. . [0003] Taiwan Patent No. M326304 (hereinafter referred to as Patent No. 304) discloses a single-box 2.1-channel speaker, which is mainly composed of: the front panel of the speaker, the bas...

AI Technical Summary

Problems solved by technology

[0005] The speaker structure of Patent No. 304 is a built-in speaker structure to reduce the speaker body and cost. However, the built-in speaker has its inherent defects, and the reduction in the volume of the speaker will affect its low-frequency effect.

[0006] In addition, the speaker structure of Patent No. 923 divides the sound source part into a treble part and a bass part, and outputs them to the corresponding tweeter and woofer to enhance the sound field effect of the sound signal source output, but this method also increases the sound field effect of the speaker. size and cost
