The utility model relates generally to sound processing techniques field, particularly a kind of speech input device 100, the especially mounting structure of vehicle mounted multimedia microphone.
As shown in Figure 1 to 11, according to the speech input device 100 of the utility model embodiment, comprising: panel 1, microphone 2, silica gel sheath 3, cover plate 4 and pressure pad 5.
Specifically, with reference to Fig. 3, panel 1 being formed with through hole 101, microphone 2 can being propagated into by light-transmitting panel 1 for making sound, and the surface of panel 1 is provided with around through hole 101 and with week of through hole 101 along isolated sleeve 11, that is through hole 101 is positioned at the inner side of sleeve 11.With reference to Fig. 2, it is interior and relative with through hole 101 that microphone 2 (microphone, i.e. MIC) is located at sleeve 11, and that is sound can be received by microphone 2 through through hole 101.With reference to Fig. 2, silica gel sheath 3 is located in sleeve 11, and the coated microphone 2 of silica gel sheath 3 at least partially, and the coated microphone 2 of silica gel sheath 3 is in order to isolated or reduction noise, make noise through silica gel sheath 3 by microphone 2 structure, or the noise received by microphone 2 cannot be reduced.With reference to Fig. 2 and Figure 11, cover plate 4 be connected with sleeve 11 also capping sleeve 11 away from one end of panel 1.Pressure pad 5 to be located in sleeve 11 and to be against on panel 1 by microphone 2, and pressure pad 5 is against on cover plate 4 away from one end of panel 1, and that is, pressing plate 4 compresses pressure pad 5, thus makes pressure pad 5 fix microphone 2.
According to the speech input device 100 of the utility model embodiment, silica gel sheath 3 is adopted to build a relative airtight environment with the mode that pressure pad 5 combines to microphone 2, thus the noise that minimizing microphone 2 receives, improve the quality of the sound that microphones arrives.
Wherein, panel 1 of the present utility model can be plane plate shape, also can for being formed in the flange shape on the inner peripheral surface of sleeve 11 end.
As shown in Figures 2 and 4, in examples more of the present utility model, silica gel sheath 3 comprises cylindrical shell 31, the inner peripheral surface of one end of cylindrical shell 31 is formed with flange 32, microphone 2 is located in cylindrical shell 31, and microphone 2 is against flange 32 for the end face receiving sound, in other words, microphone 2 is formed with the phonetic function region for receiving sound, the end face at place, phonetic function region is against on flange 32, and due to the middle part of flange 32 be empty, therefore, sound can propagate into the phonetic function fishing zone of microphone 2 by through hole 101 and flange 32, and cannot propagate into microphone 2 from other position.Thus, by the side face of the coated microphone 2 of silica gel sheath 3 and a part for a side end face, wherein, the end face be against on flange 32 of microphone 2 be microphone 2 for receiving the face of one end of sound, the noise that microphones arrives can be reduced further.
Wherein, the end face of microphone 2 is protruded in the phonetic function region of microphone 2, the inner peripheral surface of flange 32 can be configured to into the shape with the phonetic function region adaptation of microphone 2, thus make phonetic function region be engaged in the middle part of microphone 2, microphone 2 coordinates convenient stable with silica gel sheath 3, but also microphone 2 can be facilitated to receive sound.
In addition, the centre hole co-axially align of through hole 101 months flanges 32.
Advantageously, microphone 2 and cylindrical shell 31 interference fit, and fit in the surface of a part for the end face of microphone 2 and flange 32.Thus, adopt the mode of interference and laminating to coordinate microphone 2 and silica gel sheath 3, effectively can stop noise, improve the recording effect of microphone.
As shown in Figure 5, in embodiments more of the present utility model, pressure pad 5 is formed with holding tank 501 towards one end of panel 1, and microphone 2 and silica gel sheath 3 are contained in holding tank 501, and the inner peripheral surface of the outer peripheral face of silica gel sheath 3 and holding tank 501 is fitted.Thus the opposite side end face relative with phonetic function region of microphone 2 is completely cut off by pressure pad 5, and can insulating noise further, improve the recording effect of microphone.
Advantageously, as shown in Fig. 3 or Fig. 5, the sidewall of sleeve 11 is formed with the first slot to make way 102, the sidewall of holding tank 501 is formed with second slot to make way 502 relative with slot to make way, the lead-in wire of microphone 2 stretches out sleeve 11 by the first slot to make way 102 and the second slot to make way 502.Thus easily the lead-in wire of microphone 2 is drawn, facilitate the line of microphone 2.
In addition, also the lead-in wire of microphone 2 one end away from panel 1 from sleeve 11 can be drawn, that is, the lead-in wire of microphone 2 is arranged between the inner peripheral surface of sleeve 11 and pressure pad 5, thus lead-in wire is drawn from one end away from panel 1 of sleeve 11, wire lead slot can also be formed on pressure pad 5 or the lead-in wire of microphone 2 is drawn by fairlead.
As shown in Figure 2, in specific embodiments more of the present utility model, the week of cover plate 4, annular flange 41 was set on the outer peripheral face of sleeve 11 away from one end of panel 1 along being formed with annular flange 41.Thus, by cover plate 4 intactly capping sleeve 11 away from panel 1 one end thus realize the stable assembling of cover plate 4 and sleeve 11, but also the sealing effectiveness of this speech input device 100 can be improved, increase the ability of insulating noise.
Further, as shown in Fig. 2, Fig. 3 and Figure 11, at least one in sleeve 11 and panel 1 is provided with fixed leg 12, and cover plate 4 is affixed with fixed leg 12.Thus, by fixed leg 12, cover plate 4 is fixed on sleeve 11, the stability of cover plate 4 can be improved, thus improve stability and the leak tightness of whole speech input device.
Advantageously, as shown in Figure 6, cover plate 4 is formed with the mounting hole 401 corresponding with fixed leg 12, the end of fixed leg 12 is through mounting hole 401 and by nut locking cover plate 4.That is, be bolted and cover plate 4 is fixed on sleeve 11, thus can cover plate 4 be fixed on sleeve 11 actv., and cover plate 4 is stablized with the combination of sleeve 11, and assembling and convenient disassembly.
Preferably, fixed leg 12 is spaced apart multiple along the circumference of sleeve 11.Thus further increasing sleeve 11 stability fixing with cover plate 4.
