[0031] In addition, the present invention also provides a method for preparing the above-mentioned passive radiation panel, which includes the following steps: uniformly mixing various materials; and molding the mixed materials by hot pressing or injection molding to form the above-mentioned passive radiation panel. plate.

[0032] In addition, the above preparation method also includes setting a weight plate on the passive radiation plate, and the passive radiation plate is installed on the sound box equipment. The role of the weight plate is to provide the inertial force for the vibrating structure in the speaker to vibrate back and forth.

Abstract

The invention discloses a passive radiant panel and a preparation method thereof. The passive radiant panel is prepared by combining vinyl-terminated dimethylmethylvinyl (siloxane and polysiloxane), dimethyldimethoxysilane, silica gel and hydroxyl-terminated dimethyl (siloxane and polysiloxane) according to a certain percent by weight. The passive radiant panel can solve the problem that in the prior art, a loudspeaker has a poor bass effect.

Description

technical field [0001] The invention relates to the field of sound boxes, in particular to a passive radiation plate used for sound boxes and a preparation method thereof. Background technique [0002] For small speakers or mini speakers, due to volume limitations, the speakers used cannot be too large. Generally, speakers with 2 inches or less are used. When vibrating, the amount of air pushed is very small, and the sense of low volume is directly related to the volume of air pushed by the speaker. In this way, the inherent defects of the mini speaker lead to the lack of bass. [0003] The passive radiation plate (also known as passive radiation film, passive diaphragm) can better solve this problem. In fact, the structure of the passive diaphragm is somewhat similar to that of the horn, and both have the function of pushing air. The diaphragm and the surrounding ring needed to restore the diaphragm to its normal position, but the difference is that there is no driving mec...
