Problems solved by technology

[0004] The first is the shape of the acoustic enhancement material particles and the limitation of filling technology. Specifically, it is difficult for the acoustic enhancement material particles to fill the filling area 100% in the speaker cavity space, that is, there will still be empty space for the particles in the cavity. free movement;
[0005] In addition, when the speaker is working, the diaphragm pushes the airflow, and the airflow pushes the particles, causing the particles to vibrate, causing the particles to collide with each other and between the particles and the speaker shell, resulting in the occurrence of the above situation

Embodiment 1

[0058] The present embodiment provides a separation device for fixing an acoustic enhancer, wherein the manufacturing process of the separation device and its assembly with the acoustic enhancer are as follows:

[0059] The stainless steel grid and aluminum plate with a thickness of 0.1mm are selected as the base material, and are made into a cubic container with an internal volume of 9.9mm×9.9mm×9.9mm by means of stamping, welding and other processes, at least one surface of which is a stainless steel grid surface. The side length of a single mesh hole in the stainless steel mesh is 180 μm. Fill as many zeolite particles (particle size 200-400 μm) as possible into the container, and the final filling amount is 0.86cc, and then package to reach the initial state of assembly.

[0060] Mechanical force is applied in any one or more of the three axial directions of the container, so that one or more surfaces of the container are recessed inwards, so as to realize the compact wrap...

Embodiment 2

[0062] The present embodiment provides a separation device for fixing an acoustic enhancer, wherein the manufacturing process of the separation device and its assembly with the acoustic enhancer are as follows:

[0063] The heat-shrinkable PET mesh cloth with a thickness of 0.1 mm is made into a bag-shaped container, the length and width of which are 12 cm×12 cm, and the aperture is 1.5 cm; the container is laid on the inner surface of a cylindrical mold. Fill as many activated carbon particles as possible (particle size 2cm) into the container, the final filling amount is 260cc, and then encapsulate, the apparent volume of the container after encapsulation is 370cm 3 , to reach the initial state of assembly.

[0064] The packaged bag-shaped container and mold were heat-treated at 110°C for 20 minutes, so that each side wall of the container was recessed inward to realize the tight wrapping of the internal activated carbon particles, and then demolded to reach the assembled st...

Embodiment 3

[0066] The present embodiment provides a separation device for fixing an acoustic enhancer, wherein the manufacturing process of the separation device and its assembly with the acoustic enhancer are as follows:

[0067] Take a polypropylene rubber mesh cloth with a thickness of 0.1 mm, its length and width is 10 mm × 10 mm, and the aperture is 350 μm; the mesh cloth is bonded to the rear cavity wall of the speaker to form a limited space together with the rear cavity wall. Fill as many porous metal oxide sheets as possible (the shortest side length of the sheet is 400-600μm) in the limited space, the final filling amount is 0.95cc, and then encapsulate, the apparent volume of the limited space after the thickness of the sheet is packaged about 1cm 3 , to reach the initial state of assembly.

[0068] The rear cavity of the speaker is treated with ultraviolet light for 20 minutes, so that the mesh cloth is recessed into the limited space, so as to realize the tight wrapping of ...

Abstract

The invention provides a separating device for fixing an acoustic reinforcing member and an assembling method and application thereof, the separating device is assembled in a rear cavity of a loudspeaker, and a space for filling the acoustic reinforcing member is formed independently or together with other parts of the loudspeaker except the separating device. At least one part of the separating device is breathable and acoustically transparent, when one or more deformation triggering conditions are applied, the at least one part of the separating device can deform, and after one or more deformation triggering conditions are applied, the separating device tightly wraps the acoustic enhancing piece in the space. According to the separation device provided by the invention, the acoustic enhancement pieces are fixed in the specific space of the rear cavity, and when the structure is assembled in the loudspeaker rear cavity of the terminal equipment, the limited loudspeaker rear cavity can be filled with the acoustic enhancement pieces as many as possible so as to further improve the acoustic performance of the loudspeaker; the reliability of the loudspeaker can be greatly improved; and the acoustic performance of the loudspeaker can be improved.

Description

technical field [0001] The invention relates to a separation device for fixing an acoustic reinforcement piece, an assembling method and application thereof, and belongs to the technical field of electro-acoustic products. Background technique [0002] European patent EP2424270 discloses a technology of virtually increasing the rear cavity of a speaker by using zeolite materials. By arranging acoustic enhancement materials such as zeolite, activated carbon and other acoustic enhancement materials with gas adsorption and desorption capabilities in the speaker cavity, the performance of the speaker is improved in the cavity. Under the condition of constant volume, it can achieve the same performance as when the cavity volume is expanded to several times the original volume. In recent years, this technology has been widely used in speakers of smartphones, tablet computers, thin and light notebook computers, etc., enabling it to achieve better sound performance in the case of li...
