Abstract
The dust-proof microphone silica gel sheath of the utility model, technical purpose are to provide a kind of dust-proof microphone silica gel sheath that can prevent dust and audio frequency effect is promoted when sound channel inputs.Include a microphone being set on circuit board and shell, shell is equipped with a silica gel sheath fixing groove, silica gel sheath fixing groove is equipped with a shell acoustic aperture, a silica gel sheath is equipped in silica gel sheath fixing groove, silica gel sheath is equipped with transaudient channel, the transaudient channel connection shell acoustic aperture and the input acoustic aperture on silica gel sheath, input acoustic aperture are set to above microphone.The utility model thus good dustproof effect, voice transmission and microphone reception are splendid.
Description
Technical field
The utility model is related to a kind of silica gel sheaths, more specifically, being related to a kind of dust-proof microphone silica gel sheath.
Background technology
In the prior art, the micro- shape microphone being set on circuit board puts class meeting causes acoustic control ineffective because of envelope dirt
It is quick, and user's impression is influenced in normal use.In current techniques, type microphone on remote controler there is dust protection effects
Bad technological deficiency becomes those skilled in the art's technical problem anxious to be resolved.
Invention content
The technical purpose of the utility model is that there is volumes to be transmitted across for the microphone that overcomes on remote controler in the prior art
Cheng Bujia and the easy technical problem for covering dust and causing sense sound effective value bad；There is provided one kind can prevent dust and
The dust-proof microphone silica gel sheath of audio frequency effect is promoted when sound channel inputs.
Dust-proof microphone silica gel sheath, includes a microphone being set on circuit board and shell, and shell is equipped with a silica gel
Fixing groove is covered, silica gel sheath fixing groove is equipped with a shell acoustic aperture, is equipped with a silica gel sheath in silica gel sheath fixing groove, silica gel sheath is equipped with
Transaudient channel, the transaudient channel connection shell acoustic aperture and the input acoustic aperture on silica gel sheath, input acoustic aperture are set in microphone
Side.
Further, the transaudient channel is an audio-amplification structure.
The advantageous effects of the utility model are：Since shell acoustic aperture be connected to but not coaxial with input acoustic aperture formation, mistake
The structure opened can make to cover in dust microphone more difficult to get access；Thus good dustproof effect, and transaudient channel uses audio-amplification structure,
It reduces dust inlet port and increases transmission quality, voice transmission and microphone reception are splendid.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Specific implementation mode
In conjunction with Fig. 1, the embodiment of the utility model is described in detail, but claim is not limited in any way.
In Fig. 1, the dust-proof microphone silica gel sheath of the utility model includes a microphone being set on circuit board 301
300 and shell 100, shell 100 is equipped with a silica gel sheath fixing groove 101, and silica gel sheath fixing groove 101 is equipped with a shell acoustic aperture
102, a silica gel sheath 200 is equipped in silica gel sheath fixing groove 101, silica gel sheath 200 is equipped with transaudient channel, the transaudient channel connection
Shell acoustic aperture 102 and the input acoustic aperture 201 on silica gel sheath 200, when mounted when finished product, input acoustic aperture 201 is right against miaow
First 300 top.Transaudient channel is an audio-amplification structure.When implementing, the one side periphery that silica gel sheath 200 corresponds to input acoustic aperture 201 is set
There are dustband, dustband and 200 integrated injection molding of silica gel sheath, to the further dust-proof processing of microphone 300 in shell 100.Input sound
A vibrating membrane is equipped in hole 201.
The utility model is dual dust-proof, and good dustproof effect, laser propagation effect is splendid, is that this field one was not only practical but also novel
Technological improvement.
