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] like 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] like figure 1 and figure 2 As shown collectively, the vibration system 20 includes a voice coil 26 , and the voice coil 26 includes a cylindrical skeleton and a coil 260 wound on one end of the skeleton near the magnetic circuit system 30 . The vibrating system 20 also includes a ring 24 whose inner edge is bonded to the outer periphery of 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] like figure 1 and image 3 Commonly shown, the inner edge of the ring 24 is superimposed and fixed with a backing ring 28, the inner surface of the ...

Embodiment 2

[0037] This embodiment is basically the same as Embodiment 1, the difference is that:

[0038] The magnetically permeable part is a T iron, and 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.

[0039] The loudspeaker of the present invention adds a backing ring on the inner edge of the ring, the backing ring strengthens the strength of the inner edge of the ring, reduces the probability of its deformation, and reduces the difficulty of operation when the ring is bonded to the skeleton; at the same time, the backing ring Fixed on the ring, it is equivalent to increasing the bonding area between the ring and the skeleton, enhancing the bonding firmness between the two, making it less likely t...

Abstract

The invention discloses a loudspeaker and relates to the technical field of electro acoustic products. The loudspeaker comprises a casing. A vibration system and a magnetic circuit system are accommodated in the casing. The vibration system comprises a voice coil and a folding ring adhered to the skeleton periphery of the voice coil. A pad ring is superposed and fixed on the inner edge of the folding ring. The inside edge of the pad ring and the inside edge of the folding ring are adhered to the skeleton periphery. The loudspeaker provided by the invention solves the technical problems of poor folding ring adhering consistency, poor acoustic performance and the like of a loudspeaker in the prior art, and has the advantages of good consistency, high acoustic performance, good sound quality, high production efficiency, high reliability and long 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...
