Problems solved by technology

Usually, in order to facilitate assembly, the above-mentioned mesh is made of metal material, which has high hardness and is easy to locate during assembly. However, due to the limitations of materials and processes, the metal mesh is relatively thick, and the mesh aperture of the metal mesh is generally relatively large. More than 0.1mm, it cannot be made smaller, resulting in poor waterproof and dustproof effect and prone to rust, which will adversely affect the performance of the speaker module

Embodiment 1

[0028] Such as figure 1 As shown, an assembly method of a non-metallic flexible net at the sound hole of a loudspeaker module, wherein the non-metallic flexible net used in this embodiment is a nylon net, which can save costs. Of course, it can also be other known plastic nets. The thickness The choice is 0.05~0.3mm, the mesh aperture is 0.03~0.1mm, further, in order to achieve better results, the thickness can be controlled at 0.05~0.1mm, the specific thickness can be 0.05mm, and the mesh aperture can be controlled at 0.03~ 0.05mm. Compared with the use of metal mesh, non-metallic flexible mesh can be made thinner, which can reduce the occupied space and will not increase the product volume; and the aperture of its mesh can be made very small, which can improve the waterproof and dustproof performance of acoustic devices , and will not rust, improving the service life and reliability of acoustic devices.

[0029] The assembly method among the present invention specifically ...

Embodiment 2

[0037] The difference between this embodiment and the first embodiment is that: between the above-mentioned step (2) and step (3), the material is removed on both sides of the flexible mesh belt 2 corresponding to each hollow hole 11 to form two The material removal holes 21 form a flexible mesh span beam 22 between the two material removal holes 21 . In step (3), the first injection molding body 31 is formed on the flexible mesh span beam 22 , the length of the flexible mesh span beam 22 is greater than the length of the first injection molding body 31 , and it completely covers the first injection molding body 31 in the width direction. Bore. In the above steps, before the first injection molding, first remove the material on both sides of the flexible mesh belt 2 corresponding to each hollow hole 11, so that the simple operation on the flat flexible mesh belt 2, compared with the first injection molding After the body 31 is formed, the two sides are cut, which is easier to...

Abstract

The invention discloses a method for assembling a non-metallic flexible net at sound holes of an acoustic device. The method comprises the following steps of (1) manufacturing a base plate, and forming a plurality of hollow holes in the base plate; (2) manufacturing a non-metal flexible net belt, adhering the flexible net belt to the base plate, and covering all hollow holes; (3) putting the base plate adhered with the flexible net belt into a first injection mold, and carrying out injection molding on the flexible net belt corresponding to each hollow hole to form annular first injection molding bodies which are combined together with the flexible net belt; (4) cutting the flexible net belt around the first injection molding bodies, so as to obtain an independent first injection molding piece; and (5) putting the first injection molding piece into a second injection mold, carrying out secondary injection molding to form an acoustic device casing which is combined together with the first injection molding piece, and using inner holes of the first injection molding bodies as the sound holes of the acoustic device. The method has the advantages that the assembly of the non-metal flexible net belt is convenient for operation, and the assembly efficiency and the assembly quality are improved.

Description

technical field [0001] The invention relates to an assembly process of an acoustic device, in particular to an assembly method of a non-metallic flexible net at a sound hole of an acoustic device. Background technique [0002] In an acoustic device, a mesh is usually arranged at the position of the sound hole of the housing for waterproofing, dustproofing or adjusting the acoustic performance. For example, speaker modules in acoustic devices are widely used in consumer electronic products such as mobile phones and notebook computers. They include a housing and a speaker unit fixed in the housing. The sound hole of the speaker unit is transmitted from the sound hole to the outside of the speaker module, and the sound hole is provided with a mesh for waterproof and dustproof and to improve the acoustic performance. Usually, in order to facilitate assembly, the above-mentioned mesh is made of metal material, which has high hardness and is easy to locate during assembly. Howeve...
