Abstract
The utility model relates to an electret microphone vibrating film strip, which comprises a metal strip. The utility model is characterized in that one face of the metal strip is pasted with a piece of film; the metal strip is provided with two lines of positioning holes, a vibrating ring inner diameter hole and a vibrating ring outer diameter are arranged between positioning holes; the vibrating ring inner diameter hole and the vibrating ring outer diameter have a same center, a ring between both of which is a vibrating ring which extrudes towards the face of the metal strip without being pasted with film. A gap of the vibrating ring outer diameter is provided with a supporting hole through a punching way. The utility model saves time and labor when in production with improved automation degree, keeps the good consistent of the vibrating film products and prevents the scuffing, resonance frequency transferring and loss phenomena of the vibrating film caused by collision in the transporting and turning process.
Description
Technical field
The utility model relates to a kind of vibration diagram of electret microphone band.
Background technology
The diaphragm that the vibrating membrane of electret microphone is shaken ring and is attached to the ring one side of shaking by the independently circular sheet metal of producing with pressing equipment constitutes.The volume of ring is less owing to shake, and manufacturing in the engineering of vibrating membrane, such as gluing and pad pasting sheet, cut diaphragm, needs the great amount of manpower resource.In addition, because a large amount of manual operations causes the vibrating membrane consistency of product relatively poor, cause scuffing, the resonance frequency transfer of product in transportation and the circular flow easily because of colliding with and lose.
Summary of the invention
The purpose of this utility model provide a kind of making save time, laborsaving, automaticity is high, can keep vibrating membrane homogeneity of product vibration diagram of electret microphone band preferably.
For achieving the above object, the utility model is by the following technical solutions:
Vibration diagram of electret microphone band described in the utility model comprises metal tape, and its characteristics are: be pasted with diaphragm on the one side of metal tape; Have the two registration holes that utilize pressing equipment and mould to stamp out on the metal tape in its both sides, between two registration holes, be provided with by required different size stamp out successively shake the ring inner diameter hole, the ring external diameter shakes; The ring external diameter that shakes is a concentric circles with the ring inner diameter hole that shakes, and the annulus between the two is the ring that shakes, and the hoop metal tape that shakes is not pasted the one side protrusion of diaphragm.
Punching press has supported hole between the space of the described ring external diameter that shakes.
The utility model saves time, laborsaving, automaticity improves when making, and keeps the vibrating membrane consistency of product better, has also avoided vibrating membrane to cause scuffing, the resonance frequency transfer of product because of colliding with in transportation and circular flow and loses phenomenon.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
A kind of vibration diagram of electret microphone band, as shown in Figure 1, comprise metal tape 1, on the one side of metal tape 1 by epoxide resin type glue or the gluing diaphragm 6 that posts of propylene class, diaphragm 6 be on materials such as FEP, PET, PPS the method by vacuum plating to be coated with thickness be 1.5～20 microns Au or Ni or Al or the Cr or the Ni/Cr coat of metal; Have the two registration holes 2 that utilize pressing equipment and mould to stamp out in its both sides on the metal tape 1, the effect of location hole 2 is repeatedly in the punching course metal tape 1 accurately to be located; Between two registration holes 2, be provided with by required different size stamp out successively shake the ring inner diameter hole 3, shake the ring external diameter 4; The ring external diameter 4 that shakes is concentric circles with the ring inner diameter hole 3 that shakes, and the annulus between the two is the ring 5 that shakes, and the one side that the ring 5 that shakes is not pasted diaphragm to metal tape 1 is protruded.Shake ring during external diameter 4 in punching press, carry out punching press, control the degree of depth of punching press well, the ring 5 that shakes that forms after the punching press still is being connected under the situation that is not subjected to external force on the metal tape 1, just can come off from metal tape 1 as long as apply external force a little from diaphragm 6 one sides.
Because the characteristic of metal material, through after the punching press repeatedly, metal tape 1 distortion that is distorted easily influences next step accurate location.For fear of metal tape 1 torsional deformation, can between the space of ring external diameter 4 that respectively shakes, supported hole 7 be arranged punching press.
Claims (2)
1. a vibration diagram of electret microphone band comprises metal tape (1), it is characterized in that: be pasted with diaphragm (6) on the one side of metal tape (1); Have the two registration holes (2) that utilize pressing equipment and mould to stamp out on the metal tape (1) in its both sides, between two registration holes (2), be provided with by required different size stamp out successively shake the ring inner diameter hole (3), shake the ring external diameter (4); The ring external diameter (4) that shakes is concentric circles with the ring inner diameter hole (3) that shakes, and the annulus between the two is for shaking ring (5), and the one side that the ring (5) that shakes is not pasted diaphragm to metal tape (1) is protruded.
2. vibration diagram of electret microphone band according to claim 1 is characterized in that: punching press has supported hole (7) between the space of the described ring external diameter (4) that shakes.
