Embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, first embodiment of the utility model microphone comprises: the guard 3, that a gripping member 2, is arranged at these gripping member 2 tops is installed on the sound head 4 in this guard 3, and one is fixed in shockproof unit 5 in this guard 3 with this sound head 4 shockproofly.

The tubulose that extends presented down in these gripping member 2 summarys, one switching device 21 is installed on its outer peripheral face, its inside can be used for assembling relevant amplifying circuit, wireless radio frequency circuit or battery is installed, but the non-feature technology of the present utility model of its internal structure, below no longer explaining also more be not described with graphic.

This guard 3 has one and is spirally connected and is installed on the lower cover 31 on these gripping member 2 tops, and a upper outlet body 32 that is assembled in these lower cover 31 tops.The upper peripheral edge of this lower cover 31 has ring plate 311 under the tubulose, has an external screw thread 312 on the outer peripheral face of this time ring plate 311, and the lower edge of inner peripheral surface has a flange 313.The bottom of this lower cover 31 has the base ring sheet 314 of a uprise shape, has the internal thread 315 on these gripping member 2 tops that are spirally connected on the inner peripheral surface of these base ring sheet 314 lower ends.Upper outlet body 32 lower periphery of this guard 3 have ring plate 321 on the tubulose, upward have an internal thread 322 on the inner peripheral surface of ring plate 321, this upper and

lower cover body

32,31 is exactly to utilize the internal and external screw thread 322,312 of this upper and lower ring plate 321,311 to be spirally connected fixing mutually.This guard 3 is surrounded on outside this sound head 4, to prevent that sound head 4 from being collided and fault.

The diameter that the profile summary of this sound head 4 is cylindric and second end is little than the diameter of first end, and its major function is to be to convert audio signal to the signal of telecommunication, and sees through a plurality of leads 41 signal of telecommunication is transferred to amplifying circuit or radio circuit in this gripping member 2.General can be divided into two kinds of moving-coil type and condenser types according to its structure.This sound head 4 is the main element of general microphone, and non-latent structure of the present utility model, this no longer explaining more.

This shockproof unit 5, be to make by the rubber material is one-body molded, and have a bustle pipe that extends up and down 51, and radially be positioned at these bustle pipe 51 inner peripheral surfaces and the axially extended wire casing 53, of going up radially extends ring wall 52 end faces and the following wire casing 54 that is communicated with wire casing 53 bottoms this on, a plurality of upright and be spaced in bustle pipe 51 outer peripheral faces and outward extending rib 55, and center on the retainer ring 56 that is connected on these rib 55 outer side edges toward the ring wall 52, of interior extension by 51 times ora terminalis of this bustle pipe.

This bustle pipe 51 and this ring wall 52 define one jointly and are used to fill in the accommodation space of adorning these sound head 4 second ends.This upper and lower wire casing the 53, the 54th is used for ccontaining this sound head 4 and transmits the required lead 41 of the signal of telecommunication, and lead 41 passes this ring plate and extends in this gripping member 2 behind this upper and lower wire casing 53,54.These 551 base angles 552, rib 55 bottoms are to be tip-angled shape and to extend to this bustle pipe 51 outer rims below, and the cross section of these ribs 55 is to present outer narrow inner width, and are rough triangular in shape.And this retainer ring 56 is exactly to fill in to adorn on following ring plate 311 inner peripheral surfaces that are fixed in this lower cover 31 and support to be put on the flange 313 of this time ring plate 311.

Whereby, this sound head 4 is placed in this bustle pipe 51, and these retainer ring 56 plugs are loaded on these lower cover 31 inner peripheral surfaces, make this bustle pipe 51 fixedly be suspended to the central authorities of this retainer ring 56 by these ribs 55.That is to say that this sound head 4 fixedly is suspended in this guard 3 by this shockproof unit 5.Because the cross section of these ribs 55 is triangular in shape, rib 55 and this retainer ring 56 to be connected area little, when this guard 3 or this gripping member 2 are collided by user's hand, these ribs 55 are alleviated the vibrations that collision is caused with the junction slight elasticity distortion of this retainer ring 56, avoid shaking reaching sound head 4 and sending puff puff sound equipment.

As shown in Figure 4, microphone of the present utility model is when being subjected to external force collision excessive, these rib 55 distortion are bigger, the bottom 551 of rib 55 is touched on base ring sheet 314 inner peripheral surfaces of this guard 3 and is out of shape, the vibrations of buffering external force collision, avoid vibrations to reach this sound head 4, and can prevent that this sound head 4 is because of the collision fault.The base ring sheet 314 of this guard 3 is longer in the present embodiment, and bump is that these base ring sheet 314 upper limbs are touched and strain in the bottom 551 of rib 55 when big.As when being used in the short guard 3 of other base ring sheet 314, be to touch of the vibrations of the upper limb of this base ring sheet 314 with buffering collision of closed by the tip-angled shape base angle 552 of this rib 55.

As Fig. 5 and shown in Figure 6, second embodiment of the utility model microphone and the structure of first embodiment are roughly the same, and its difference is in the ring wall 52 that does not have among first embodiment in this shockproof unit 5 and reaches wire casing 54 down, and the base angle 552 of these rib 55 no tip-angled shapes.The rib 55 of this shockproof unit 5 is connected on the inner peripheral surface of this retainer ring 56 by radially extending outward on the outer peripheral face of this bustle pipe 51.Second end plug of this sound head 4 is loaded in this bustle pipe 51, and first end is because of the big last ora terminalis that fastens in this bustle pipe 51 of diameter.Retainer ring 56 plugs of this shockproof unit 5 are loaded on these lower cover 31 inner peripheral surfaces, make these bustle pipe 51 interior sound head 4 elasticity be suspended to the central authorities of this retainer ring 56 by these ribs 55, just are suspended in this guard 3, with the vibrations of buffering collision of closed.

As shown in Figures 7 and 8, the 3rd embodiment of the utility model microphone and the structure of second embodiment are roughly the same, its different place is that this sound head 4 is general capacitive sound heads 4, this sound head 4 has a columned radio reception portion 42, and is coated on ring stand 43 on the outer peripheral face of radio reception portion 42, a plurality ofly is fixed in these pole 44 upper ends covering on the sponge 45 of these radio reception portion 42 tops at interval by the upwardly extending pole 44, of these ring stand 43 apical margins, and a collar flange 46 that is radially extended outward by the outer peripheral face of this ring stand 43.And this shockproof unit 5 also has one by inside oblique upward the extension to coat the ring-type support sheet 57 of these radio reception portion 42 end face peripheries of ora terminalis on this bustle pipe 51, reaches one and results from these bustle pipe 51 inner peripheral surfaces with the horizontal annular groove 58 outside the flange 46 that is sleeved on this sound head 4.Has the breach 571 that these poles 44 of a plurality of confessions wear on the inner peripheral of this support sheet 57.By the annular groove 58 of this bustle pipe 51 and help sheet 57, the radio reception portion 42 of this sound head 4 is fixed in the bustle pipe 51, cause this sound head 4 to be arranged in this shockproof unit 5 vibrations with buffering collision of closed.

Take a broad view of above-mentioned, the sound head 4 of the utility model microphone is by the support of this shockproof unit 5 and be fixed in this guard 3, and because the special exterior design of these ribs 55, and this guard 3 of available buffer and gripping member 2 are collided the vibrations that cause, avoid sound head 4 to be sent the sound because of shaking, it is very convenient therefore to use.
