Embodiment Construction

[0018] The implementation of the present invention will be described in more detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it after studying this specification.

[0019] refer to Figure 4A and Figure 4B , are respectively the top view of the first embodiment of the horn elastic wave with different hardness in the present invention, and the first embodiment of the horn elastic wave with different hardness in the present invention, with Figure 4A The enlarged side view of the B-B' section in the middle, the section of the horn wave in all directions is the same as the B-B' section, and only the B-B' section is taken as an example. like Figure 4A and Figure 4B As shown, the horn spring 50 of the present invention with different hardness includes a body 60 and a rubber coating 71 . The body 60 is a kind of circular body made of fabric impregnated with resin, has a central through hole 65 for connecting the voice...

Abstract

The invention discloses a horn elastic wave with different hardness and a manufacturing method thereof. The horn elastic wave comprises a body and at least one glue coating, wherein the glue coating is made of a high-elastic plastic material and is arranged on the predefined area of the surface of the body, so the horn elastic wave has at least two types of different hardness. The method comprises a resin impregnation step, a glue-coating setting step and a coining and forming step. By adopting the horn elastic wave with different hardness and the manufacturing method disclosed by the invention, the glue-coating arranged on the body can form a horn elastic wave with different hardness, thus reducing the horn noise, improving resilience capacity and the low frequency output effect of the horn, and further objectively adjusting on the basis of user preferences.

Description

technical field [0001] The invention relates to a horn spring wave and a manufacturing method thereof, in particular to a horn spring wave with different hardness and a manufacturing method thereof. Background technique [0002] refer to figure 1 , is a side view of the internal structure of the horn in the prior art. like figure 1 As shown, the speaker internal structure 1 includes a housing 10 , a magnetic core 20 , a voice coil 30 and a wave 40 . The magnetic core 20 is arranged in the casing 10, the outer surface of the voice coil 30 is wound with a coil to connect to an external power source, and is connected to the magnetic core 20. When the current passes, electromagnetic induction is generated to vibrate up and down. The elastic wave 40 is connected to the casing 10 and has The central through hole 45 is used to connect the voice coil 30 . The elastic wave 40 must be light in weight, have a certain degree of hardness and elasticity, so as to fix the voice coil 30 ...
