Embodiment
In order more to understand feature of the present utility model place, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The first embodiment: the present embodiment provides a kind of microphone 1 of convertible directive property, please refer to Fig. 1-Fig. 3, the primary clustering of microphone 1 includes a microphone body 10 and an adjusting mechanism.
Please first with reference to figure 1, microphone body 10 is probably hollow cylinder, microphone body 10 has the first side 11 near this sonic sensor 20, and be looped around 12, the first sides 11, the second side around, this first side 11 and offer a plurality of sound holes 13 and the second side 12 that are radial arrangement and offer a pore 14.Microphone body 10 has more a sonic sensor 20 and is arranged at and in microphone body 10, is used for receiving sound, and sonic sensor 20 forms a front sound chamber 15 towards a side of the first side 11 and the internal face of microphone body 10, sonic sensor 20 forms a rear sound chamber 16 with the internal face of microphone body 10 away from a side of the first side 11 relatively, the outside of sound chamber 15 and microphone body 10 before described sound hole 13 connections, and pore 14 is communicated with the outside of rear sound chamber 16 and microphone body 10.
Please continue to refer to Fig. 2, adjusting mechanism includes a holder 30 and is used for fixing microphone body 10, holder 30 includes a junction 31, connecting portion 31 concaves and has the first relative internal face 312 and the second internal face 313, and is connected in one the 3rd internal face 314 between the first internal face 312 and the second internal face 313.The upper end of the 3rd internal face 314 has a stopper section 311.Wherein, the pore 14 of the corresponding microphone body 10 in stopper section 311 arranges, and in the present embodiment, stopper section 311 can be sound-absorbing foam or an elastomeric material.Certainly, those skilled in the art can integrate stopper section 311 and connecting portion 31 easily.In addition, the below of holder 30 is provided with a joint 32, and joint 32 is electrically connected sonic sensor 20 with transmitting signals.
In addition, adjusting mechanism also includes a pivot structure 40, makes the microphone body 10 can be with respect to holder 30 pivotable between a pore enable possition (as Fig. 2) and a stomatal closure position (as Fig. 3).In the time that microphone body 10 is positioned at pore enable possition, stopper section 311 does not cover pore 14, and in the time that microphone body 10 is switched to stomatal closure position, stopper section 311 covers pore 14, and makes rear sound chamber 16 reach gas-tight effect.
In use, in the time that the staff of radio reception need to be made as unidirectivity by the directional property of microphone 1, staff can be by microphone body 10 towards the direction pivotable away from stop portion 311, rear sound chamber 16 must be communicated with outside by pore 14, as shown in Figure 2, now, sonic sensor 20 will be received from front sound chamber 15 and with the sound wave effect in rear sound chamber 16, the major part of sound wave in environment be repealed by implication, and reservation faces the sound wave of the first side 11.
Relatively, in the time that the staff of radio reception need to be made as non-directive by the directional property of microphone 1, staff can be by microphone body 10 towards the direction pivotable near stopper section 311, make stopper section 311 cover pore 14, now sonic sensor 20 only can receive the sound from front sound chamber 15, no longer include the mutual effect of sound wave and occur, so directive sound wave in can complete reception environment.
Therefore, the staff who is responsible for radio reception can, according to actual environment and different demands in use, simply by pivotable microphone body 10, just can be adjusted the directional property of microphone 1 and reach good radio reception effect for the utility model.
The utility model provides one second embodiment again, please refer to Fig. 4-Fig. 5, the primary clustering of the second embodiment and the first embodiment are roughly equal, and its Main Differences is: the upper end of the internal face of the cylindrical and connecting portion 521 of the connecting portion 521 of holder 52 has a stopper section (not shown), the internal diameter of connecting portion 521 is slightly larger than the external diameter of microphone body 51, and microphone body 51 can be sheathed in connecting portion 521.In addition, the adjusting mechanism of the present embodiment changes into and adopts a slide construction 530, it comprises two chutes 531 and two sliding bars 532 corresponding connecting portion 521 and the microphone body 51 of being arranged at respectively, make microphone body 51 relatively holder 52 and between stomatal closure position (Fig. 4) and pore enable possition (Fig. 5) slide, in the time that microphone body 51 slides into pore enable possition, pore 511 will expose to outside connecting portion 521, when microphone body 51 slides into stomatal closure position, pore 511 will submerge within connecting portion 521, and then make stopper section cover pore 511, the function of adjusting microphone directive property can be provided equally.
The utility model separately provides one the 3rd embodiment, please refer to Fig. 6-Fig. 7, wherein microphone body 61 forms a recess 611 in the position indent of the second corresponding pore 612 in side 613, and the adjusting mechanism of the present embodiment is to be by one the switch member 62 that tabular and size is greater than pore 612, and one slide construction 630 form, this slide mechanism 630 comprises two projection (not shown) and two chutes 632 and is arranged at respectively internal face and the switch member 62 of recess 611, make switch member 62 be located at slippingly this recess 611, and then slide between pore enable possition and stomatal closure position, as shown in Figures 6 and 7, allow switch member 62 control the unlatching of pore 612 or to close.
What supplement at this is, previous embodiment has proposed various adjusting mechanism, the connection means that can use holder or switch member collocation to rotate or slide, and the concrete structure that connects means in each embodiment is also different, explanation widely provides the enough guides of those skilled in the art can adopt or derive other equivalent structures.
Finally; what must again illustrate is; the utility model in the aforementioned embodiment disclosed constituent components only for illustrating; not be used for limiting the protection range of this case; every other easy full of beard and structural change; or with the alternate variation of other equivalent elements, all should be encompassed in the protection range of this case.
