Abstract
The utility model belongs the field of condenser microphone. A connecting ring is arranged under a circuit board group, a sheet damping is arranged under the connecting ring, a damp is arranged in the sheet damping, a back plate is arranged under the sheet damping, the connecting ring, the damp and the back plate are arranged in a back base, a pad is arranged under the back base, all of which are arranged in a housing, and the bottom of the housing is stuck with an anti-dust net. Compared with prior art, the utility model has the advantages of high anti-interference ability especially high frequency electromagnetic wave, wide frequency range with a 50-20khz frequency response and high sensitivity with adopting the high gain ECM exclusive use IC chip amplifying circuit, the sensitivity is over 10 dB higher than common uni-direction product, and the directivity of heart shape, ultra-heart shape and sharp-heart shape can satisfy the require of different occasions.
Description
Technical field
The utility model belongs to the condenser microphone field.
Background technology
Microphone is widely used in people's every field such as life, and its weak point is that common condenser type list directional microphone volume is big, and sensitivity is lower, and frequency band range is narrower, and interference free performance is relatively poor.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of volume of providing is less, interference free performance is high, wide frequency range and highly sensitive single condenser microphone that points to.
The purpose of this utility model can realize by following measure:
Under the wiring board group, connecting ring is set, under connecting ring, damping sheet is set, damping is set in the damping sheet, under the damping sheet back pole plate is set, connecting ring, damping sheet and back pole plate are set in the back-pole base, under the back-pole base pad are set, under the pad diaphragm is set, said structure is arranged in the shell, and outer casing bottom pastes Air Filter.
1PCS high-gain ECM application-specific integrated circuit chip and 2PCS electric capacity are set on the wiring board group 1; Build-in IC chip amplifying circuit structure is made up of amplifier, FET, resistance, electric capacity, earthing device.
The utility model has following advantage compared to existing technology:
1. interference free performance height, particularly frequency electromagnetic waves;
2. wide frequency range, frequency response is 50～20KHz;
3. adopt high-gain ECM application-specific integrated circuit chip amplifying circuit, more common single the sensing more than the high 10dB of product of sensitivity;
4. directive property is designed to heart type, super core shape, and acute core shapes etc. are multiple, can satisfy different occasion needs.
