Abstract
The utility model discloses an improved electric connector for microphone, which comprises a metal ring body, and a heat shrinkage tubular insulating layer fitted outside cylindrical surface of the metal ring body. With configuration of the heat shrinkage tubular insulating layer, the inventive electric connector has the following advantages: (1) material is widely available, processing is extremely simple and only needs to cut to desired length, and material cost is greatly reduced; and (2) there is no need for interference fit during assembling process, the insulating layer can be tightly fit around the metal ring body by heating with hot air after assembling.
Description
Technical field
The utility model relates to a kind of transducer that is used to receive sound wave with the signal of telecommunication that converts the expression sound wave to, relates in particular to the arrangements of electric connection of a kind of microphone inside.
Background technology
Disclose multiple electret microphone in the prior art, they all are equipped with the capacitor unit that is made of battery lead plate and film, are used to receive sound wave to convert the signal of telecommunication of expression sound wave to.
On June 2nd, 1999 Chinese patent disclosure a kind of denomination of invention be " electret capcitor microphone ", the patent No. technical scheme for " 97246455.7 ", its basic structure is as shown in Figure 3: the cylindrical shape of a through hole, an end opening is arranged at the bottom that the shell 72 of microphone, cavity 76 are made into for metal material, mould the annular that ring 75, shading ring 77 are made into for plastics or nonmetallic materials, the annular that the ring 73 that shakes is made into for metal material is pasted fixedly dustcloth 71 and vibrating diaphragm 74 respectively on the inner surface of the basal surface of shell 72 and the ring 73 that shakes.Source electrode on the microphone pipe 78, drain electrode are weldingly fixed on the wiring board 79, and shading ring 77 is a tight fit in around the outer wall of cavity 76.To be installed on the bottom of shell 72 with ring 73 loose fits of shaking of vibrating diaphragm 74 successively, put into the cavity 76 of moulding ring 75, having shading ring 77, the wiring board 79 that has microphone pipe 78 again, at last the top edge turnover bag pressure of shell 72 is lived wiring board 79, the pressure that produces during bag pressure embeds in the perisporium of cavity 76 the input utmost point grid of microphone pipe 78.
The shortcoming of the above technical scheme is: as the cavity 76 of arrangements of electric connection and the shading ring 77 between the shell 72, adopt ambroin to make, because volume is less and have certain interference fit, makes and still assemble all relatively difficulty.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, improved microphone arrangements of electric connection of being convenient to process and assemble.
For achieving the above object, the technical solution of the utility model is: improved microphone arrangements of electric connection, between a pole plate of the printed substrate of microphone and electric capacity, be used to be electrically connected a pole plate of printed substrate and electric capacity, comprise the metal ring body, the cylindrical side face portion of described metal ring body is socketed with the heat-shrinkable T bush insulating barrier.
Because adopt technique scheme, improved microphone arrangements of electric connection comprises the metal ring body, the cylindrical side face portion of described metal ring body is socketed with the heat-shrinkable T bush insulating barrier; The setting of heat-shrinkable T bush insulating barrier, its advantage is: 1, material is easy to get, and processes very simply, as long as length is cut off on demand, material cost reduces greatly; 2, assembling is convenient in no interference restriction in the assembling process, promptly is fastened on the metal ring body with the hot blast heating after assembling is finished.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the user mode figure of the utility model embodiment;
Fig. 3 is the structural representation of background technology.
Embodiment
As shown in Figure 1, improved microphone arrangements of electric connection between a pole plate of the printed substrate of microphone and electric capacity, is used to be electrically connected a pole plate of printed substrate and electric capacity, comprise metal ring body 1, the cylindrical side face portion of described metal ring body 1 is socketed with heat-shrinkable T bush insulating barrier 2.
As shown in Figure 2, the operation principle of microphone is as follows: when external sound after the pore on the shell 5 passes to vibrating diaphragm 3, vibrating diaphragm 3 produces vibration, this vibration changes the distance of 4 of vibrating diaphragm 3 and back pole plates, vibrating diaphragm 3 has corresponding variation with the capacitance of the electric capacity that back pole plate 4 is formed, because of the electret static content on the back pole plate 4 can not change, the electric weight that is capacitor is constant, and the variation of capacitance just causes the variation of capacitor voltage at both ends, the variation of this voltage need pass to the printed substrate 6 of microphone and carry out signal processing by the electronic devices and components on the printed substrate 6, wherein back pole plate 4 electrically connects by the input of shell 5 with printed substrate 6, vibrating diaphragm 3 electrically connects with printed substrate 6 another inputs by metal ring body 1 of the present utility model, and the effect of heat-shrinkable T bush insulating barrier 2 is to guarantee that metal ring body 1 is not short-circuited with shell 5.
Claims (1)
1. improved microphone arrangements of electric connection, between a pole plate of the printed substrate of microphone and electric capacity, be used to be electrically connected a pole plate of printed substrate and electric capacity, comprise metal ring body (1), it is characterized in that: the cylindrical side face portion of described metal ring body (1) is socketed with heat-shrinkable T bush insulating barrier (2).
