Description
Technical field
This utility model relates to mike technique field, be specifically related to a kind of can the electret microphone of underwater performance.
Background technology
Mike, formal name used at school isMicrophone, it is by soundSignalBe converted to the signal of telecommunicationEnergy is changedDevice, by " Microphone " this English word transliteration.Also referred to asMicrophone, mike.Twentieth century,MikeWind is by initially passing throughResistanceConversion acoustic-electric develop into inductance,Electric capacityFormula is changed, and the newest microphone techniques gradually grows up, and includes among theseAluminium strip、Moving-coilDeng mike, and it is currently being widely usedElectric capacityMike and electret microphone.
Existing electret microphone structure can only accomplish maximum waterproof IP56 by waterproof cloth.Owing to tone-entering hole communicates with interiors of products structure, therefore steam or globule infiltration can be there is, and then product may be made to enter steam and cause disabler.The microphone needing operation under water not only needs preferable water resistance, with greater need for preferable sound sensitivity.Existing underwater performance microphone there is also certain deficiency.
Utility model content
The purpose of this utility model be to provide a kind of can the electret microphone of underwater performance, this microphone had both possessed preferable water resistance, possessed again preferable sound sensitivity.
For achieving the above object, the following technical scheme of this utility model offer:
nullA kind of can the electret microphone of underwater performance，Including tubular shell，This housing bottom is provided with acoustic aperture，Above-mentioned housing bottom is equipped with the first vibration sound film，The lower surface of above-mentioned first vibration sound film and the inner surface of above-mentioned housing bottom at least one side is coated with waterproof sealing glue-line，The second vibration sound film it is equipped with in above-mentioned housing，This second vibration sound film is positioned on above-mentioned first vibration sound film，Ring pad it is equipped with in above-mentioned housing，This ring pad is positioned on above-mentioned second vibration sound film，It is equipped with plate mat in above-mentioned housing，This plate mat is positioned on above-mentioned ring pad，Above-mentioned plate mat is provided with through hole，Resonance inner chamber it is equipped with in above-mentioned housing，This resonance inner chamber is positioned in above-mentioned plate mat，It is equipped with resonant external cavity in above-mentioned housing，This resonant external cavity is sheathed on outside above-mentioned resonance inner chamber，Above-mentioned case top is provided with transaudient chip，This transaudient chip is positioned at housing.
Preferably, above-mentioned first vibration sound film includes the sandwich structure being made up of fibrous layer, cork wood layer and fibrous layer.
Preferably, above-mentioned second vibration sound film includes the sandwich structure being made up of fibrous layer, cork wood layer and fibrous layer.
Preferably, it is equipped with dustcloth outside above-mentioned housing bottom.
Preferably, the lower surface of above-mentioned vibration sound film and the inner surface of above-mentioned housing bottom are coated with waterproof sealing glue-line.
Operation principle of the present utility model is: be uniformly coated with waterproof sealing glue-line between the acoustic aperture and the first vibrating diaphragm of microphone, makes the acoustic aperture of microphone and microphone case be internally formed two separate space being not attached to lead to.By this waterproof construction, thus improve the water resistance of microphone.
First vibration sound film acts primarily as the effect intercepting water under water, and is provided with the second vibration sound film, and the second vibration sound film is mainly used in sensing acoustic pressure, picks up acoustical signal effect, substantially increases the sound sensitivity of microphone.
The beneficial effects of the utility model are: microphone had both possessed preferable water resistance, possess again preferable sound sensitivity.
Accompanying drawing explanation
