Problems solved by technology

Since the ring is generally soft, it is difficult to ensure the firmness of the bond when it is bonded to the voice coil frame. There is a gap between the inner side of the ring and the voice coil frame, resulting in glue leakage and poor bonding quality. It is also difficult to ensure the accuracy of the bonding position, it is easy to stick to deviation, the bonding is difficult, the product consistency is poor, and the performance of the speaker will also be affected

Embodiment 1

[0028] Such as figure 1 and figure 2 Commonly shown, a loudspeaker includes a ring-shaped casing 10 , and a vibration system 20 and a magnetic circuit system 30 are accommodated in the casing 10 .

[0029] Such as figure 1 and figure 2 Commonly shown, the vibrating system 20 includes a voice coil, and the voice coil includes a cylindrical frame and a coil 260 wound on one end of the frame close to the magnetic circuit system 30 . The vibrating system 20 also includes a ring 24 whose inner edge is fixed on the skeleton, and whose outer edge is fixed on the upper surface of the shell 10 , and the ring 24 is located above the coil 260 . The vibrating system 20 also includes a DOME 22 covering the upper end of the skeleton, and the edge portion of the DOME 22 is fixed on the skeleton.

[0030] Such as figure 1 , figure 2 and image 3 Commonly shown, the skeleton includes a first skeleton 264 and a second skeleton 262 spliced ​​together up and down, the first skeleton 264...

Embodiment 2

[0035] This embodiment is basically the same as Embodiment 1, the difference is that:

[0036] The magnetically permeable part is a T-iron, ring-shaped magnets and washers are sequentially fixed on the edge of the T-iron, and a magnetic gap is provided between the magnet, the washers and the central column of the T-iron. The washer is fixed on the inner wall of the casing, and the upper surface of the washer is fixedly combined with the lower surface of the positioning boss.

[0037] The skeleton of the loudspeaker of the present invention is composed of two parts of the skeleton superimposed up and down, and the inner edge of the ring is clamped and fixed between the two parts of the skeleton, which plays a role of positioning and blocking when the ring is bonded, thereby effectively improving The consistency of the speaker is improved, and the influence of the nonlinearity of the speaker due to glue leakage is also prevented, and the acoustic performance of the speaker is im...

Abstract

The present invention discloses a loudspeaker, and relates to the electro acoustical product technology field. The loudspeaker comprises a shell in which a vibration system and a magnetic circuit system are accommodated, and the vibration system comprises a voice coil, a folding ring fixed on the skeleton of the voice coil and a DOME. The skeleton comprises a first skeleton and a second skeleton which are spliced together up and down, and the inner edge of the folding ring is fixed between the first and second skeletons. The loudspeaker of the present invention solves the technical problems in the prior art that the adhesion consistency of the folding ring of the loudspeaker is poor, the acoustic performance is poor, etc., and is good in product consistency and sound quality, high in acoustic performance, production efficiency and reliability and long in service life.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker. Background technique [0002] The loudspeaker, commonly known as the horn, is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The loudspeaker usually includes a casing, and the casing contains a vibration system and a magnetic circuit system. The magnetic circuit system includes U / T iron, magnets and washers. The vibration system includes a combined ring, voice coil and DOME (dome, dustproof cap), with the ends of the voice coil in the magnetic gap. The voice coil includes a voice coil frame and a coil wound at the end of the voice coil frame. The ring is fixed at the other end of the voice coil frame. After the coil is energized, it moves up and down in the magnetic gap, and the voice coil frame drives the ring to move and radiate sound. Since the ring is generally soft, it is dif...
