An epoxy resin glue composite sound cone

Abstract

The invention discloses an epoxy resin glue composite cone. The epoxy resin glue composite cone comprises a cone main body, the top of the cone main body is provided with a housing, the top end of theinternal part of the housing is provided with an internal housing, the top parts of the housing and the internal housing are provided with a protruding ring, the top of the protruding ring is provided with a filter screen, the bottom of the internal housing is provided with a diaphragm, and the middle position of the bottom of the diaphragm is provided with a fixed block, and the top of the fixedblock is provided with a protruding block penetrating into the top of the internal housing. According to the epoxy resin glue composite cone, the housing is directly rotated to enable the housing torotate for 360 degrees with mutual cooperation of a second slide block and an annular slide groove, the epoxy resin glue composite cone can adjust the direction according to different positions of music listeners, the usage effect of the epoxy resin glue composite cone is improved, the experience effect is improved, a polyvinyl chloride fiberglass hose is wrapped at the outside of an enameled wire so that the service lifetime of the enameled wire is prolonged, short circuit is avoided, and the usage rate is increased.

Description

technical field [0001] The invention relates to the technical field of high-pitched equipment, in particular to an epoxy resin glue composite sound basin. Background technique [0002] Epoxy resin refers to the general term for a class of polymers containing two or more epoxy groups in the molecule. It is a polycondensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of epoxy groups, it can be used in many A compound containing active hydrogen makes it ring-opened, cured and cross-linked to form a network structure, so it is a thermosetting resin, and the sound cone made of epoxy resin has a high noise-removing effect. [0003] However, the high and low frequency division of the existing epoxy resin composite sound basin is relatively vague, thereby reducing the high and low bass effect, and the existing epoxy resin composite sound basin cannot adjust the direction according to the position of the music listener. Thereby reducing the ...

[0003] However, the high and low frequency division of the existing epoxy resin composite sound basin is relatively vague, thereby reducing the high and low bass effect, and the existing epoxy resin composite sound basin cannot adjust the direction according to the position of the music listener. Thereby reducing the use effect of the epoxy resin composite sound cone, and reducing the experience effect, and the existing epoxy resin composite sound cone enameled wire lacks external protection measures, thereby reducing the service life of the enameled wire and easily causing a short circuit , thereby reducing the usage
