Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 4, the speaker includes a cone 1, a damper 2, and a frame 3. The basin frame 3 is provided with a circular ring-shaped step surface for supporting the elastic wave 2 and the periphery of the paper basin 1, the circular periphery of the elastic wave 2 is placed on the corresponding circular ring-shaped step surface of the basin frame 3, and then the ultrasonic welding equipment is utilized to weld the part of the elastic wave 2, which is lapped on the circular ring-shaped step surface, so that a welding forming layer 4 is formed. The connection of the paper cone 1 and the cone frame 3 is operated together with the connection of the elastic wave 2 and the cone frame 3, the circular periphery of the paper cone 1 is placed on the circular step surface, and a welding head of ultrasonic welding equipment is further utilized to form a welding forming layer 4, so that the welding strength of the joint of the paper cone 1 and the cone frame is close to a connected material, the welding period is short, the connection efficiency is improved, and the production period is shortened.

In addition, the periphery of the cone 1 is connected with a folded ring 11, and extends to the corresponding circular step surface through the folded ring 11, so that the ultrasonic welding forming layer is connected with the basin frame 3, and the connection structure is shown in fig. 5. The basin stand 3 comprises a truncated cone-shaped inner shell and a cylindrical outer shell, wherein the inner component is installed on the truncated cone-shaped inner shell, one end of the outer shell of the cylindrical outer shell is connected with the outer shell of the cylindrical outer shell to serve as the upper end of installation, and the other end of the cylindrical outer shell serves as the lower end of installation. In order to ensure the structural strength, the upper end of the paper cone 1, which is arranged above the joint of the cone frame 3, is sleeved with a blank holder 12. The blank holder 12 is a circular ring member which is internally sleeved in the basin frame 3 and is matched with the circular ring step surface at the position in a strong structure, so that the connection position is shielded and protected. The basin frame 3 extends upwards from the circular step surface to form a protective outer ring matched with the outer diameter of the blank holder 12, and the blank holder 12 is sleeved in the protective outer ring. And four arc-shaped notches are uniformly formed in the periphery of the protective outer ring, and the outer ring surface of the blank holder 12 protrudes outwards to form a clamping block matched with the arc-shaped notches, and further limits the connection position of the clamping block. For guaranteeing the connection stability of speaker, its installation lower extreme outwards extends perpendicularly and forms the location outer loop, and evenly laying of this location outer loop has a plurality of mounting hole 31, and this mounting hole 31 can be with arc breach one-to-one, and the protection outer loop is provided with the family's type groove that corresponds in its mounting hole 31 department to guarantee connecting screw's smooth entering, promote positioning strength, and reduce the relative distance of mounting hole 31 and speaker center pin. And the lower end of the lower mounting end is vertically provided with a plurality of limiting columns 33 so as to improve the connection and positioning quality. The circular-truncated-cone-shaped inner shell is formed by connecting five sectional materials with circular-ring-shaped step surfaces used for mounting the elastic waves 2 and the cone 1 respectively. The cross-section of this section bar is U type structure, when guaranteeing structural strength, its wire casing can regard as the subassembly installation passageway, promotes the dress effect entirely. And the connecting interface 32 positioned on one side of the cylindrical shell is correspondingly communicated with the section bar, so that the signal transmission quality is improved while the structural stability is ensured.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
