Description
Technical field
This utility model relates to alarm technical field, is specifically related to a kind of high temperature resistant alarm metallic membrane applied on alarm.
Background technology
Alarm is a kind of by preventing or preventing certain event that the consequence caused occurs, and reminds or warn us should take certain electronic product taken action with forms such as sound, light, air pressure.Alarm (alarm), is divided into mechanical alarm device and electronic alarm.Along with the progress of science and technology, mechanical alarm device is replaced by advanced electronic alarm more and more, is usually applied to the fields such as the system failure, safety precaution, transportation, medical aid, emergency disaster relief, sensing detection, inseparable with social production.
Product type is transferred to SMT trend by DIP processing, alarm will be suitable for the processing of SMT processing procedure from shape and material heatproof, and although sounding effect can be reached with the sounding diaphragm in traditional alarm, but the design of its structure is the most ingenious, sounding effect is undesirable, and be employing PET or PEI material and make, its heatproof is typically between 60～150 DEG C, the high temperature needs (260 DEG C/15 seconds) of SMT cannot be met, and if the structure of alarm is given up vibrating diaphragm, then sound can diminish, it is impossible to meets the big volume standard of alarm.
Utility model content
For existing above-mentioned deficiency, the purpose of this utility model is, it is provided that a kind of smart structural design, rationally, and sounding effect is good, high temperature resistant, and the high temperature resistant alarm metallic membrane of ease of assembly.
For achieving the above object, technical scheme provided by the utility model is: a kind of high temperature resistant alarm metallic membrane, it includes circular aluminum lamellar body, the home position of this circular aluminum lamellar body is downwardly concaved formation tapered recess, the bottom of this tapered recess is provided with perforate, the inward flange horizontal radial of this perforate extends and forms interior connecting portion, and the outer peripheral edge horizontal radial of described circular aluminum lamellar body extends and forms outer connecting portion.
As a kind of improvement of the present utility model, the thickness of described circular aluminum lamellar body is 0.05～0.09mm.
As a kind of improvement of the present utility model, the junction of described interior connecting portion and tapered recess uses round-corner transition, and the junction of described outer connecting portion and tapered recess uses round-corner transition.
As a kind of improvement of the present utility model, a length of the 0.8～0.12mm of described interior connecting portion.
As a kind of improvement of the present utility model, a length of the 4～6mm of described outer connecting portion.
As a kind of improvement of the present utility model, the degree of depth of described tapered recess is 6.5～8.5mm, a diameter of the 40～44mm of described circular aluminum lamellar body.
The beneficial effects of the utility model are: smart structural design of the present utility model, rationally, are integrally conical, and sounding directivity is good, and radiation effect is good, effectively promotes sounding effect；Using circular aluminum lamellar body to substitute tradition PET or PEI, not only acoustic pressure is higher, and up to about 115 decibels, and high-temperature resistant result is good, and the fusing point of aluminum is 660 DEG C, is far longer than 260 DEG C of SMT process requirements, meets the high temperature needs of SMT simultaneously；Additionally overall structure is simple, compact, easy to assembly, it is easy to accomplish, beneficially wide popularization and application, it is particularly suitable for high temperature and manufactures the application of manufacture field.
Below in conjunction with the accompanying drawings with embodiment, this utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is complete section structural representation of the present utility model.
Detailed description of the invention
Seeing Fig. 1 and Fig. 2, the one high temperature resistant alarm metallic membrane that the present embodiment provides, it includes that circular aluminum lamellar body, the thickness of described circular aluminum lamellar body are preferably 0.05～0.09mm, and voice effect is more preferably.The home position of this circular aluminum lamellar body is downwardly concaved formation tapered recess 1, the bottom of this tapered recess 1 is provided with perforate 2, the inward flange horizontal radial of this perforate 2 extends and forms interior connecting portion 3, and the outer peripheral edge horizontal radial of described circular aluminum lamellar body extends and forms outer connecting portion 4.Owing to interior connecting portion 3 and outer connecting portion 4 are horizontal plane, bring convenience to assembling procedure, and coordinate closely, be connected firmly, increase the service life.
Concrete, the length of described interior connecting portion 3 is preferably 0.8～0.12mm.The length of described outer connecting portion 4 is preferably 4～6mm.The degree of depth of described tapered recess 1 is preferably 6.5～8.5mm, and the diameter of described circular aluminum lamellar body is preferably 40～44mm.Certainly, in other embodiments, interior connecting portion 3, outer connecting portion 4, tapered recess 1 and circular aluminum lamellar body can also use other size.
It is also preferred that the left the junction of described interior connecting portion 3 and tapered recess 1 uses round-corner transition, the junction of described outer connecting portion 4 and tapered recess 1 uses round-corner transition.Furthermore it is also possible to be arranged with radially raised line in tapered recess 1 in the center of circle, one end of this radial direction raised line is connected with interior connecting portion 3, and the other end is connected with outer connecting portion 4.
