Miniature loudspeaker box with ultra-thin and ultra-low frequency structure

Abstract

The invention relates to the technical field of loudspeaker boxes and in particular to a miniature loudspeaker box with an ultra-thin and ultra-low-frequency structure. The loudspeaker box comprises abox body and a loudspeaker, wherein a sound cavity is arranged in the box body; the inner wall of the inner cavity of the sound cavity protrudes to form an accommodating groove for accommodating theloudspeaker; the loudspeaker is fixed in the accommodating groove; the accommodating groove is lower than the sound cavity; a lower opening for exposing the magnetic bowl of the loudspeaker is formedin the box body corresponding to the bottom of the loudspeaker; the box body is provided with an upper opening corresponding to the upper part of the loudspeaker; the upper opening is sealed by a stainless steel sheet; the outer wall of an expansion groove is not contacted with the inner wall of the sound cavity; the sound cavity is internally provided with expansion cavities at two sides of the accommodating groove; the height of the expansion cavity is smaller than that of the sound cavity; the opening of the expansion cavity faces one side of the magnetic bowl of the loudspeaker; the expansion cavity is filled with a gas adsorption material; and the opening of the expansion cavity is provided with breathable expansion damping cloth. The loudspeaker has better ultralow-frequency sound quality, small thickness, small size, composite use requirements and better sound effect.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a micro-speaker sound box with an ultra-thin ultra-low frequency structure. Background technique [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, mobile phones and tablet computers are the most common and portable mobile terminal devices. At present, mobile phones and tablet computers are all developing towards ultra-thin. The ultra-thin body means that the internal components must also be ultra-thin. For example, speakers must have high-quality, high-quality sound quality, and sound effects. , but also meet the design requirements of ultra-thin and small size. In order to obtain high-quality sound quality and sound effects, the speaker box has to have better low-frequency sound quality. However, for speaker sound effects, in order to obtain better low-frequency sound quality, It is nec...

Problems solved by technology

At present, mobile phones and tablet computers are all developing towards ultra-thin. The ultra-thin body means that the internal components must also be ultra-thin. For example, speakers must have high-quality, high-quality sound quality, and sound effects. , but also meet the design requirements of ultra-thin and small size. In order to obtain high-quality sound quality and sound effects, the speaker box has to have better low-frequency sound quality. However, for speaker sound effects, in order to obtain better low-frequency sound quality, It is necessary to increase the volume of the speaker box, which will increase the volume of the speaker box, which conflicts with the use requirements of ultra-thin and small volume. Therefore, the existing speaker boxes cannot meet the use requirements, and do not have low-frequency and ultra-low-frequency sound quality , the sound effect of the speaker is poor
