Abstract
The utility model provides a series of novel microphones which are formed by structure components, an acoustic electric conversion system, a signal processing system and a resonance system. The series of novel microphones are formed by adding a resonance system on the basis of a general microphone. The resonance system is formed by a diaphragm, filling medium and a supporting structure. A space is formed by the diaphragm, the filling medium and the supporting structure. The space is a resonant cavity which is a sealed space. The novel microphone is characterized in that a physical amplification system is formed through the resonance of the diaphragm and the medium (CO2, N2, O2) in the resonant cavity and acoustic wave reflection, the system firstly amplifies sound {W = W1 + W2 + W3 or LP = 10 log (P1^2 + P2^ + P3^2) / P0^2)} and then transmits the sound to the acoustic electric conversion system, and the reproduction of original sound can be achieved.
Description
Technical field:
A series of novel microphones belong to the acoustic-electric conversion equipment.
Background technology:
Present microphone mainly contains electrodynamic type, condenser type and crystal formula.These microphone electrodynamic type tonequality are best, but frequency response is subjected to the restriction of self; The condenser type frequency response is better, and tonequality is relatively good; The crystal formula is more moderate, decides with manufacturing formula skill.They all are subjected to certain restriction to remote capturing ability faint and trickle sound.
Summary of the invention: capture remote faint and trickle sound in order to make microphone, the invention provides a series of novel microphones, can capture remote faint and trickle sound, more can reach the effect of former sound reproducing.
The technical scheme that the technical solution problem adopts is: a series of novel microphones, formed by construction package, acoustic-electric converting system, signal processing system and resonator system.These a series of novel microphones are to increase a resonator system on the basis of general microphone to constitute.This resonator system is made up of vibrating diaphragm, filled media and supporting construction, and their common spaces that constitutes are resonant cavities, and it is a sealed space.Be characterized in by vibrating diaphragm and resonant cavity medium (CO2, N2, O2) resonance and acoustic reflection formation physics amplification system is first amplifies sound W=W1+W2+W3 or LP=10log[(p1 ∧ 2+p2 ∧+p3 ∧ 2)/p0 ∧ 2] and pass to the acoustic-electric converting system again, more can reach former sound reproducing.Vibrating diaphragm wherein: (one) can select light material for use, is characterized in the Hz-KHz of vibrating diaphragm greater than the auditory frequency range of people's ear, thereby guarantees the complete of voice capture; (2) the different vibrating diaphragm of several heavy local frequencies can be set in resonant cavity, be characterized in making each section of audio frequency that is in people's ear frequency range amplification of can both effectively resonating.Aforesaid resonant cavity is characterized in the inside filled media, and this medium can be CO2, O2, and N2 etc. preferably near the quality of air, to momentum unanimity inside and outside the resonant cavity, guarantees sound quality to guarantee sound wave.Aforesaid filled media is characterized in selecting for use pure molecular gas or elementary gas, in order to can guarantee the sound wave isotropism, is conducive to improve sound quality.Aforesaid filled media is characterized in that the air pressure of filled media should be consistent with atmospheric pressure, with consistent inside and outside the assurance acoustic resonance system.Aforesaid supporting construction is characterized in adopting the material with certain coefficient of elasticity to make, to promote the resonance of resonator system.Aforesaid resonant cavity is characterized in except vibrating diaphragm, adopts the material covering preferably of acoustic reflection ability, so that good reflective sound wave increases the resonator system amplification effect.
The invention has the beneficial effects as follows the resonator system physics voice emplifying by increasing, thereby can capture remote faint and trickle sound, more can reach the effect of former sound reproducing.
