Abstract
The utility model discloses a universal silica gel sleeve for a mini-type microphone which comprises a silica gel wrapping body and a sealing ring, a small hole is arranged on the terminal end of the silica gel wrapping body, an opened end of the silica gel wrapping body is partially or completely opened and is in reduce port shape, the diameter of the opened end is 0.10 to 0.20mm smaller than the diameter of the terminal end, the sealing ring can be one or a plurality around the outside surface of the silica gel wrapping body, the slope surface shape can be in a round shape, an elliptical shape, a hackle or a square; the slope surface can be continuous or discontinuous ring-shaped convex object, the universal silica gel sleeve improves the use range of single specification product, realizes versatility, and brings great convenience to production management. Simultaneously, the problems of accurate location and loose sealing in the installation process can be avoided due to the existence of a sealing ring, and the assembly efficiency and the assembly effect can be improved.
Description
Technical field
The utility model relates to a kind of element of microphone, relates in particular to a kind of general silica gel sheath that is used for mini microphone.
Background technology
The silica gel sheath that is used for mini microphone, material are black or colored silicon rubber, and hardness is spent between 75 degree 40, smooth outer surface, and no burr has certain compressibility, plays fixedly microphone and the effect that seals the microphone fit-up gap in assembling.
But existing silica gel sheath model is various, and a specification generally can only cooperate the mini microphone of a fitted position, and is very inconvenient during use.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of general silica gel sheath that is used for mini microphone is provided, and this general silica gel sheath can be used for cooperating the mini microphone of multiple fitted position.
The purpose of this utility model is achieved through the following technical solutions: a kind of general silica gel sheath that is used for mini microphone, and it comprises silica gel inclusion enclave and sealing ring, the end of silica gel inclusion enclave has aperture; The open end portion of silica gel inclusion enclave or complete opening are the reducing shape, and the openend diameter is than the little 0.10～0.20mm of end diameter; Sealing ring is to be centered around one or more of silica gel inclusion enclave lateral surface, and domatic profile is circular, oval, zigzag or square, continuous or discontinuous ring-type protrusion.
Further, the material of described silica gel inclusion enclave and sealing ring is that hardness is at 40-75 degree, black or colored silicon rubber.The inside and outside semidiameter of described sealing ring is between 0.1mm-0.5mm, and the ring width of sealing ring is between 0.2mm-1.0mm.
The beneficial effect that the utility model compared with prior art has has improved the scope of application of single specification product, has realized versatility, and production management is brought great convenience.Because the existence of sealing ring has solved and accurately located in the installation process and poorly sealed problem, efficiency of assembling and assembling effect have been promoted simultaneously.
Description of drawings
Fig. 1 is the structural representation of the general silica gel sheath of the utility model;
Fig. 2 is the domatic structural representation of ordinary silicon gum cover;
Among the figure: 1, silica gel inclusion enclave, 2, sealing ring.
Embodiment
Describe the utility model below with reference to the accompanying drawings in detail, it is more obvious that the purpose of this utility model and effect will become.
As shown in Figure 2, has only silica gel inclusion enclave 1 on the ordinary silicon gum cover.And silica gel inclusion enclave 1 openend is identical with tip radius, can only cooperate the mini microphone of a fitted position, and is very inconvenient during use.
As shown in Figure 1, the general silica gel sheath that the utility model is used for mini microphone comprises silica gel inclusion enclave 1 and sealing ring 2, the material of silica gel inclusion enclave 1 and sealing ring 2 is that hardness is at the 40-75 degree, black or colored silicon rubber, end at silica gel inclusion enclave 1 has aperture, be used for the conduction of sound, the open end portion of silica gel inclusion enclave 1 or complete opening, be used for packing into of mini microphone. for the microphone of the silica gel inclusion enclave that guarantees to pack into does not break away from from opening part, make the reducing shape at the openend of silica gel inclusion enclave 1, diameter dimension sticks in the outside of silica gel inclusion enclave 1 than the little 0.10-0.20mm. sealing ring 2 of end diameter size, be 1 of the lateral surface that is centered around silica gel inclusion enclave 1 or a plurality of, domatic profile is circular, oval, zigzag, geometry such as square, continuous or discontinuous ring-type protrusion. the inside and outside semidiameter of sealing ring is between 0.1mm-0.5mm, and the ring width of sealing ring is between 0.2mm-1.0mm.
General silica gel sheath of the present utility model has been realized the cooperation of multiple fitted position preferably by using the compressibility on a large scale of sealing ring, and the existence of sealing ring has solved the poorly sealed problem of ordinary silicon gum cover simultaneously.
Preparation process of the present utility model is: the size of Bao Guo mini microphone as required, set interior diameter, the thickness of setting the silica gel inclusion enclave simultaneously is 0.2mm-0.6mm, the inside and outside semidiameter of setting sealing ring is 0.2mm-0.5mm, selected 1 or a plurality of sealing ring are made injection mold according to the size of design.Selecting hardness is the 40-75 degree, black or colored silica gel, and by the extruding injection moulding, the demoulding then, making is finished in finishing.
Claims (3)
1. a general silica gel sheath that is used for mini microphone is characterized in that it comprises silica gel inclusion enclave and sealing ring, and the end of silica gel inclusion enclave has aperture; The open end portion of silica gel inclusion enclave or complete opening are the reducing shape, and the openend diameter is than the little 0.10～0.20mm of end diameter; Sealing ring is to be centered around one or more of silica gel inclusion enclave lateral surface, and domatic profile is circular, oval, zigzag or square, continuous or discontinuous ring-type protrusion.
2. according to the described general silica gel sheath that is used for mini microphone of claim 1, it is characterized in that the material of described silica gel inclusion enclave and sealing ring is that hardness is at 40-75 degree, black or colored silicon rubber.
