Problems solved by technology

[0002] There is an indispensable part in the loudspeaker---the edge pad. The common practice in the prior art is to punch paper with a certain thickness into the edge pad of the required shape. The disadvantages are: 1. The effect of stamping is low; 2. It is easy to produce burrs and affect the overall quality of the speaker
If rubber is heated and molded, the longitudinal section of the annular body is approximately circular, and there will be burrs, which is not suitable for loudspeakers.

Embodiment Construction

[0009] The rubber edge used for the loudspeaker shown in Fig. 1 and Fig. 2 has an annular body with a certain height, the longitudinal section 2 of the annular body 1 is rectangular, and the annular body 1 is circular.

[0010] The method of preparing the rubber edge of the speaker is to use rubber as the raw material and prepare it through the following process: 1. Heating the rubber to a temperature of 175°C; 2. Pour the rubber into the mold and press it into a tubular shape; 3. Demoulding, the inner cavity of the tubular shape A cylindrical inner liner is set, and the rubber tubular body is rotated laterally to form the speaker edge of the annular body 1 .

Abstract

The related circular rubber pad for loudspeaker has longitudinal cross-section as rectangle or circle or ellipses, and is prepared by: heating material at 160-180Deg, preparing rubber into mould to shape as tubular form; demoulding, setting inside lining as cylinder or ellipsoid, and horizontal rotated cutting the tubular object into circular body. This invention has high production efficiency and well quality.

Description

Technical field: [0001] The invention relates to a rubber edge of a loudspeaker, and also relates to a preparation method of the rubber edge. Background technique: [0002] There is an indispensable part in the loudspeaker---the edge pad. The common practice in the prior art is to punch paper with a certain thickness into the edge pad of the required shape. The disadvantages are: 1. The effect of stamping is low; 2. It is easy to produce burrs and affect the overall quality of the speaker. If rubber is heated and molded, the longitudinal section of the annular body is approximately circular, and burrs will be produced, which is not suitable for loudspeaker use. Invention content: [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a loudspeaker rubber edge with high efficacy, good quality and reasonable structure and a preparation method thereof. [0004] The rubber edge used for loudspeaker of the present invention ...
