Embodiment
Figure microphone module is made up of two microphone units 1, a plastic barrel that hardness is higher 2 and a soft rubber cover 3 as shown in Figure 1, the two ends of plastic barrel 2 and rubber sleeve 3 all are openings, a plurality of microphone units 1 plastic barrel 2 of packing into, rubber sleeve 3 is at the outside of plastic barrel 2 parcel.In the implementation case, plastic barrel 2 and rubber sleeve 3 all are to be similar to columniformly, can certainly be square column or other cylindricality.In the implementation case, plastic barrel 2 and rubber sleeve 3 are separate, a plurality of microphone units 1 plastic barrel 2 of packing into earlier, plastic barrel 2 reinstalls in the rubber sleeve 3, simultaneously plastic barrel 2 and rubber sleeve 3 can be formed in advance by technologies such as injection mouldings and reinstall microphone unit together, and a plurality of microphone units 1 have a ball-and-biscuit microphone unit 11 and single directional microphone unit 12 to constitute.Arrow has represented that sound wave propagates into the route map of microphone unit inside outside the microphone module among Fig. 1.
A described ball-and-biscuit microphone unit 11 adopts relative direction to be placed in the plastic barrel 2 with single directional microphone unit 12, and promptly the outer casing bottom spacing of two microphone units is nearest, and the wiring board spacing of two microphone units farthest.Shell 121 bottoms of wherein single directional microphone unit 12 and PCB122 go up sound hole 123 and 124 respectively, and the sound hole 113, shell 111 bottoms that ball-and-biscuit microphone unit 11 has only.
A sound hole is all arranged on the sidewall of described plastic barrel 2 and rubber sleeve 3, be respectively 21 harmony holes 31, hole, when plastic barrel 2 and rubber sleeve 3 were assembled together, these two sound holes were run through; And by these two sound holes, the sound hole 113 and 123 of ball-and-biscuit microphone unit 11 and single directional microphone unit 12 outer casing bottoms can both receive microphone module outside sound signal; Be provided with positioner between described plastic barrel and the described rubber sleeve, structure in the present embodiment is to have part projection 24 to extend in the sound hole 31 of described rubber sleeve around the sound hole 21 of described plastic barrel, can reach the effect that plastic barrel 2 and rubber sleeve 3 are fixed and located.
Position between plastic barrel 2 bosom positions, two microphone units 11 and 12 has a plastic foam 4 to separate two microphone units, and this plastic foam 4 can see through sound and air.Can be used for preventing the harmful effects such as reflection of sound.
One end margin at place, described rubber sleeve 3 parcel form directional microphone unit has exceeded plastic barrel 2, and the edge of this end flushes.The microphone module is when being combined together with positions such as electronic product shell or PCB like this, rubber sleeve 3 can at first contact positions such as electronic product casing or PCB, because the flexibility of rubber, it is bad to guarantee that microphone module internal and outside can not produce gas leakage etc.Opposite, if plastic barrel 2 positions contact electronic product casing or PCB then can cause microphone module internal and outside generation gas leakage etc. bad because of the hard and possible burr of plastic material.
Described plastic barrel 2 be equipped with single directional microphone unit 12 1 sides sidewall some vertically cut, inside and outside run through, become a U-lag 22, this U-lag 22 and rubber sleeve 3, single directional microphone unit 12 common passages that form are used for settling the wiring of single directional microphone unit 12, and make microphone module outside sound see through sound hole 113,123 on plastic barrel 2 and the rubber sleeve 3 and this passage 22 and propagate into sound hole 124 on single directional microphone unit 12 wiring boards 122, and propagate into 12 inside, single directional microphone unit.
There are two vertical grooves 23 in the sidewall of plastic barrel 2 outside as described in shown in accompanying drawing 2, accompanying drawing 3, the barrel attenuation of groove 23 partly plastic tubes runs through inside and outside still cutting fully and causing, the groove 23 corresponding positions of the inwall of above-mentioned rubber sleeve 3 and above-mentioned plastic barrel 2 have the approximate groove 32 of two sizes equally, the jacket wall attenuation of groove 32 part rubber sleeves 3 runs through inside and outside still cutting fully and causing, plastic barrel 2 lateral wall grooves 23 and two tubular through holes of rubber sleeve 3 inboard grooves, 32 common formation, the wiring of in this through hole, arranging the ball-and-biscuit microphone unit.
On described as shown in Figure 4 rubber sleeve 3 sidewalls three through holes are arranged, the through hole 33 that size is bigger, the through hole 34 of two undersized, two wirings of above-mentioned single directional microphone unit 12 through hole 34 by two undersized is connected with the electronic product wiring board beyond being directed to the microphone module; Two wirings of ball-and-biscuit microphone unit 11 form two tubular through holes jointly by above-mentioned plastic barrel 2 lateral wall grooves 23 and rubber sleeve 3 inboard grooves 32, are directed to outside the microphone module by through hole 33 to be connected with the electronic product wiring board again.
The further improvement of the implementation case is, two wirings of above-mentioned single directional microphone unit 12 and two through holes 34 on rubber sleeve 3 sidewalls are airtight combining.Can guarantee that the outer air of microphone module can not be transmitted to the microphone module internal by these two through holes 34.
There is a projection 35 at the position that described rubber sleeve 3 outsides do not comprise hole 31, be square in the implementation case,, the microphone module can be installed on the wiring board or shell of electronic products such as mobile phone by this square projection, thereby convenient assembling, the raising efficiency of assembling of cooperating.
3 hole 31 exterior circumferential of described rubber sleeve have the concordant projection 36 of a circle, the implementation case protrusions shape is square, be used for and the wiring board or the shell of electronic product such as mobile phone cooperate, the wiring board or the shell that can guarantee microphone module and electronic product cooperate closely bad generations such as anti-leak-stopping sound.
In the cooperation of 3 holes 31 of described rubber sleeve and electronic product, on the position at sound pairing electronic product casing in hole or PCB place a sound hole is arranged also, guarantee that 3 holes 31 of rubber sleeve can receive the extraneous sound wave that sends of electronic product; Settling on the position at the pairing electronic product casing of rubber sleeve 3 one sides of single directional microphone 12 or PCB place also has a sound hole, comes the sound hole 124 on bonding directional microphone 12 wiring boards 122 can receive the extraneous sound wave that sends of electronic product.
As shown in Figure 5, the earth connection 115 of the earth connection 125 of described single directional microphone 12 and ball-and-biscuit microphone 11 is connected and fixed by a plastic sheath 5 after passing rubber sleeve 3 and welds together.To make the wiring of microphone module become simply like this, and can make and save a pad on the wiring board of terminal electronic product.
By this execution mode, microphone unit is assembled to and will becomes easy in the microphone module, the microphone module is assembled to and also can becomes easy in the electronic product, and this microphone module can reach running through of sound channel and seal, for microphone array forms the voice signal that the pickup bundle effectively picks up to be needed, it is bad to prevent that the reflection of sound wave etc. from appearring in electronic product inside.
The implementation case is only for describing a listed embodiment of the present invention; under the prerequisite that does not change purport of the present invention; can make the change of multiple scheme to the implementation case; for example can be used in combination in pairs; and be installed in the common housing; should be appreciated that all within protection scope of the present invention.
