Description

A kind of silicone earphone speaker speaker diaphragm and preparation method of diaphragm

technical field

The invention relates to the field of sound box earphones, in particular to a silicone earphone speaker speaker diaphragm and a preparation method for the diaphragm.

Background technique

The diaphragm is the main sound-generating device in the earphone or speaker, and its quality determines the sound effect of the entire speaker or earphone. The diaphragms in the prior art are generally made of plastic, metal, wood, and paper. The diaphragms made of these materials have poor elasticity when vibrating, cannot be deformed arbitrarily, have poor vibration effects, and have poor sound quality. The production cycle is long, the production cost is high, and the color adjustment is inconvenient. Therefore existing vibrating membrane also has many weak points.

Contents of the invention

The technical problem to be solved by the present invention is to provide an outer ring made of silica gel material, which has good elasticity, softness and ductility, greatly eliminates or reduces the deformation effect on the dome, has small distortion, and achieves a high-fidelity loudspeaker Silicone earphone speaker speaker diaphragm according to requirements and preparation method of diaphragm.

The present invention is achieved through the following technical solutions: a silicone earphone speaker speaker diaphragm, including a diaphragm used for vibration in earphones or sound boxes, the diaphragm includes an inner ring and an outer ring, and a gap between the inner ring and the outer ring Mutual bonding, the inner ring is set in the middle of the outer ring, and the outer ring wraps the entire inner ring;

The inner ring is made of plastic or metal material, and the metal material is copper; the outer ring is made of silicone material.

As a preferred technical solution, both ends of the outer ring and the inner ring are provided with an arc connecting section.

As a preferred technical solution, a square-shaped cavity is reserved in the middle of the outer ring, the four surfaces of the inner ring are arranged in the cavity, and part of the inner ring is exposed to the air.

A method for preparing a silicone earphone speaker speaker diaphragm, specifically comprising the following process steps:

Step 1. According to the size parameters of the specific product, the corresponding inner ring is produced, that is, the inner ring is made of metal or plastic materials;

Step 2: Adhesive treatment is applied to the surface of the plastic parts and the metal parts so that they can be thermally vulcanized and bonded to the silica gel of the outer ring;

Step 3. Put the metal or plastic parts into the forming mold, and then put in the silica gel to form the fluorosilicone and firmly bond with the metal or plastic parts;

Step 4. When molding, reserve a cavity in the middle of the outer silicone ring to ensure that part of the end face of the inner ring is exposed to the air;

Step 5, cooling the above formed diaphragm and performing post-processing.

The beneficial effects of the present invention are: the present invention adopts the silica gel material to make the outer ring, since the silica gel is a high-strength, elastic and oil-proof material, if it is used as the outer ring part, the vibrating membrane will be greatly deformed when the high-pitched sound is played. The outer ring part has good elasticity, softness and ductility, which greatly eliminates or reduces the deformation effect on the dome, and the distortion is small, which meets the requirements of high-fidelity speakers.

As shown in Fig. 1, a kind of silicone earphone sound box loudspeaker diaphragm of the present invention comprises the diaphragm that is used for vibration in earphone or sound box, and this diaphragm comprises inner ring 2 and outer ring 1, and inner ring 2 and outer ring 1 They are bonded to each other, the inner ring is set in the middle of the outer ring, and the outer ring wraps the entire inner ring;

The inner ring 2 is made of plastic or metal material, and the metal material is copper; the outer ring 1 is made of silicone material.

Both ends of the outer ring 1 and the inner ring 2 are provided with a circular arc connecting section; a square-shaped cavity is reserved in the middle of the outer ring, and the four faces of the inner ring are set in the cavity, and part of the inner ring is exposed on the in the air.

During production, according to the size parameters of the specific product, the corresponding inner ring is made, that is, the inner ring is made of metal or plastic material; then the surface of the plastic part and the metal part is treated with an adhesive to make it bond with the silicone of the outer ring by heat vulcanization ;Finally put the metal or plastic parts into the forming mold, and then put in the silica gel to form the silica gel and firmly bond with the metal or plastic parts;

During molding, a cavity is reserved in the middle of the silicone outer ring to ensure that part of the end face of the inner ring is exposed to the air; then the formed diaphragm is cooled and post-processed.

Silica gel is a high-strength, elastic and oil-proof material. When it is used as the outer ring part, the vibrating membrane will be greatly deformed when the high-pitched sound is played, and the outer ring part has good elasticity, softness and ductility, which greatly eliminates the Or reduce the deformation effect on the dome, and the distortion is small
