Example Embodiment

[0033] Step 1: The preparation method of the silica gel diaphragm includes the following steps:

[0034] Step 2: Provide silica gel film 4;

[0035] Step 3: The silicone film 4 is continuously introduced into the cavity 31 of the molding machine 3;

[0036] Step 4: Clamp the mold and control the mold temperature;

[0037] Step 5: Adjust the molding pressure and keep the pressure for a period of time, so as to realize the secondary molding of the silicone film 4;

[0038] Step 6: Take out the silicone diaphragm 1 after forming, the thickness of the silicone diaphragm 1 is not uniform.

[0039] It is understandable that the silica gel film used in the embodiment of the present invention is a substrate-free silica gel film, and the method of preparing the silica gel diaphragm used in the embodiment of the present invention is to perform secondary molding with a substrate-free silica gel film that has been preliminarily formed.

Example Embodiment

[0049] Example 1:

[0050] This embodiment provides a method for preparing a silica gel diaphragm, which sequentially includes the following steps:

[0051] Step 1: Provide the molded silicone film 4;

[0052] Step 2: Introduce the molded silicone film 4 into the cavity 31 of the molding machine 3 in a continuous manner, so that the silicone film 4 remains flat in the cavity 31;

[0053] Step 3: Clamp up and down or left and right molds, and control the temperature of the upper and lower molds or left and right molds to 155°C;

[0054] Step 4: Adjust the molding pressure to 20MPa;

[0055] Step 5: Keep the pressure for 1 minute;

[0056] Step 6: Take out the molding and prepare the silicone diaphragm 11.

Abstract

The invention provides a preparation method for silica gel diaphragms. The preparation method comprises the steps of providing silica membrane; continuously importing the silica gel membrane into the mould cavities of moulding machines; closing the moulds and controlling the temperature of the moulds; adjusting moulding pressure, and keeping the pressure for a period of time; and taking out the silica gel diaphragms after moulding is finished. The silica gel diaphragms are nonuniform in thickness. The preparation method for the silica gel diaphragms is simple in technology operation, and convenient and fast in moulding. According to the method, large-scale preparation can be realized, and high performance is displayed in different audios.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a silicone diaphragm, a preparation method of the silica gel diaphragm and a sound-generating component using the silica gel diaphragm. Background technique [0002] The loudspeaker is an important component of portable electronic equipment. It is used to convert the sound wave electrical signal into a sound signal. conversion quality. The diaphragm of the existing loudspeaker is generally made of materials such as PET and PEEK. Silicone elastomer is a fatigue-resistant, aging-resistant, and high-temperature-resistant material. Its chemical composition and physical structure determine that it has many characteristics that other similar materials cannot replace: good damping, good thermal stability, stable chemical properties, It has high mechanical strength, etc., so silica gel can replace PET, PEEK and other materials as diaphragms, and has a good prospect. [0003] At p...
