Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a double-folded cone structure and loudspeaker. Background Technology

[0002] A loudspeaker is an important acoustic component in portable electronic devices. It converts electrical sound waves into sound signals and transmits them as an energy conversion device.

[0003] Many modern speaker products require small size (thin profile) and high power with high sound quality due to structural limitations. There are generally two types of traditional speaker structures: 1. High-power, large-volume structure (relatively thick). This structure is suitable for speakers of various diameters, offering high power output and good sound quality. However, due to its large size, additional supports are needed to ensure the speaker operates at high power. Figure 4 As shown.

[0004] 2. Low-power, compact (thin) structure. This structure is suitable for small-diameter loudspeakers, with lower power consumption and generally lower sound quality. It is suitable for applications where overall space is limited. Due to the structural size limitations, relying solely on the cone surround to provide support for the vibration system only ensures the reliability of the loudspeaker at low power operation. Figure 5 As shown. Utility Model Content

The protruding direction of the first convex part is opposite to the direction of the conical surface of the vertebra, and the protruding direction of the second convex part is the same as the direction of the conical surface of the vertebra.

[0011] In one embodiment of the present invention, the outer edge of the vertebral body is provided with a first connecting portion, which is a planar annular portion.

[0012] In one embodiment of the present invention, the first folding ring includes a second connecting portion and a third connecting portion, both of which are annular, and the second connecting portion and the third connecting portion are respectively connected to both ends of the first protrusion, and one side of the second connecting portion and the first connecting portion are connected.
