Loudspeaker

Abstract

The invention relates to a loudspeaker. The loudspeaker comprises a magnetic circuit component, a vibration component and a fixing member which is used for fixing the magnetic circuit component and the vibration component, and a tubular member; the magnetic circuit component comprises U iron, and a magnetic body and a spring washer which are sequentially stacked in the U iron; the vibration component comprises a vibration membrane, a spider and a sound ring; the spider comprises a ripple part and a supporting part which is used for fixing the ripple part; both ends of the tubular member are respectively connected with the ripple part of the spider and the vibration membrane; the ripple part is arranged on the periphery of the tubular member; a through hole is formed in the middle of the spider; the fixing member passes through the through hole to separate the supporting part and the U iron; and the sound ring is arranged on the vibration membrane. Because the tubular member is arranged in the loudspeaker, the spider is arranged on the periphery of the tubular member, and the two ends of the tubular member are respectively connected with the spider and the vibration member, the U iron is encircled by the spider; compared with that of the conventional loudspeaker of which the spider is arranged on the U iron, the thickness of the loudspeaker is reduced; therefore, the spider can be effectively prevented from being collided with the U iron, and the stroke of the loudspeaker is increased.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic equipment, in particular to a loudspeaker. 【Background technique】 [0002] In the rapidly developing digital age, ultra-thin LCD TVs, computers, monitors, and various sound-emitting thin digital devices have higher and higher requirements for the thickness of speakers. But the traditional loudspeakers are all made very thick, and the U-iron is installed outside the speaker bracket; or the U-iron is placed in the bracket, such as Figure 4 As shown, the upper part of the spring wave 210 is directly connected to the voice coil 220, so that the distance between the spring wave 210 and the U iron 230 is too close to cause collisions, which limits the development of the sound cavity in a thinner direction, resulting in higher power and larger diameter. It is difficult to make the woofer ultra-thin. 【Content of invention】 [0003] Based on this, it is necessary to provide a thinner speaker. [0004]...

AI Technical Summary

Problems solved by technology

But the traditional loudspeakers are all made very thick, and the U-iron is installed outside the speaker bracket; or the U-iron is placed in the bracket, such as Figure 4 As shown, the upper part of the elastic wave 210 is directly connected with the voice coil 220, so that the elastic wave 210 is too close to the U iron 230 to easily collide, which limits the development of the sound cavity in a thinner direction, resulting in higher power and larger diameter woofers are hard to make ultra-thin
