Embodiment 1

[0056] ginseng Figure 4-6 , the vibration assembly 13 includes a voice coil part 12 and a diaphragm part 14 . The voice coil part 12 includes a skeleton 121 and a voice coil body 123 . The frame 121 includes a base 1211 and an extension 1213 . The base body 1211 is roughly a hollow cylinder. The base body 1211 includes an upper edge 1212 and a lower edge 1214 opposite to the upper edge 1212 . The upper edge 1212 and the lower edge 1214 are respectively located on opposite sides of the base 1211 . The extension portion 1213 is formed by extending the upper edge 1212 away from the lower edge 1214 . The extension portion 1213 is recessed toward the central axis X direction. The voice coil body 123 is disposed around the outer surface of the base body 1211 .

[0057] The diaphragm part 14 includes a main body 141 , a first connection part 143 and a second connection part 145 . The first connecting portion 143 and the second connecting portion 145 are substantially on the s...

Embodiment 2

[0059] ginseng Figure 7 The difference between embodiment 2 and embodiment 1 lies in that in embodiment 2, although the cross section of the body 141 is arched, the edge of the body 141 close to the extension portion 1213 is recessed relative to the extension portion 1213 .

Embodiment 3

[0061] ginseng Figure 8 The difference between embodiment 3 and embodiment 1 is that the cross section of the body 141 in embodiment 3 is approximately circular. That is to say, the body 141 includes two opposite arc-shaped portions 1411 . The two arc portions 1411 are connected between the first connecting portion 143 and the second connecting portion 145 . The concave surfaces of the two arc-shaped portions 1411 are disposed opposite to each other to form the body 141 with a substantially circular cross-section.

Abstract

A vibration system comprises a first support and a vibration assembly. The vibration assembly comprises a voice coil part and a vibrating diaphragm part. The voice coil part comprises a framework anda voice coil body; the framework comprises a base body, wherein the base body is annular, and the voice coil body is annularly arranged on the outer surface of the base body. A through hole is formedin one end, far away from the voice coil body, of the base body; the through hole penetrates through the base body; the vibrating diaphragm part comprises a first connecting part, a second connectingpart and a body, the body is arranged between the first connecting part and the second connecting part, the first connecting part is connected with the first support, and the second connecting part isannularly connected to one end, far away from the voice coil body, of the base body and fills the through hole. The invention further provides a loudspeaker with the vibration system and a manufacturing method of the vibration system.

Description

technical field [0001] The present application relates to the technical field of electro-acoustic products, in particular to a vibration system, a loudspeaker and a manufacturing method of the vibration system. Background technique [0002] In recent years, due to the increasing requirements of the market for the functional characteristics of the speaker, the vibration system is the main component of the speaker's vibration and sound, and its quality / design / material selection largely determines the sound effect of the speaker. At present, various types of glue are usually used to bond the vibration components in the loudspeaker vibration system. However, due to the difficulty in guaranteeing the consistency of glue coating, it is easy to cause large tolerances in the assembly of various components, which greatly affects the acoustic performance of the speaker. Contents of the invention [0003] In view of this, it is necessary to provide a vibration system for improving t...
