Abstract
The utility model discloses a coaxial -type is fidelity structure for speaker relates to a speaker fidelity structure. In the coaxial -type speaker, basin frame is connected with magnetic circuit, and the bass cone is located the basin frame, and the tweeter horn is located the bass cone, still includes the round platform in the coaxial -type speaker, the non - enclosed construction of round platform for only constituting by the side, the upper and lower plane of round platform respectively with the upper and lower plane coincidence of tweeter horn, the side of round platform is located bass cone and tweeter horn within a definite time, the surperficial random distribution of round platform the aperture. Surface distribution the round platform structure of aperture, makes the reflection path change, the effective attenuation near the reflected energy of frequency 1000Hz, improved the partial frequency response characteristic of woofer, played the effect of fidelity.
Description
Technical field
The utility model relates to a kind of loud speaker fidelity structure, particularly a kind of coaxial loudspeaker fidelity structure.
Background technology
In the coaxial loudspeaker of conventional art, frame is connected with magnetic circuit system, bass cone is positioned at described frame, tweeter horn is positioned at described bass cone, tweeter horn surface smoothing, makes the sound wave of bass cone radiation be subject to the strong reflection on tweeter horn surface, especially the sound wave of frequency near 1000Hz, have a strong impact on the acoustical behavior of coaxial loudspeaker medium and low spectrum loudspeaker part, particularly the Frequency Response of woofer part.
Summary of the invention
The purpose of this utility model is to provide a kind of coaxial loudspeaker fidelity structure, reduces tweeter horn to the reflections affect of the acoustic pressure of bass cone radiation, improves the frequency response performance of coaxial loudspeaker medium and low spectrum loudspeaker, avoid occurring distortion.
In order to achieve the above object, the utility model adopts following technical scheme:
Coaxial loudspeaker fidelity structure, in coaxial loudspeaker, frame is connected with magnetic circuit system, and bass cone is positioned at frame, and tweeter horn is positioned at bass cone, the equal flare shape of frame, bass cone and tweeter horn, also comprise round platform in coaxial loudspeaker, round platform is the non-close structure be only made up of side, and the lower planes of round platform overlaps with the lower planes of tweeter horn respectively, the side of round platform is positioned between bass cone and tweeter horn, and round platform surface random distribution aperture.
Preferably, the utility model coaxial loudspeaker is with in fidelity structure, and the thickness of frustum cone side is 3mm.
Preferably, the utility model coaxial loudspeaker is with in fidelity structure, and the hole diameter of frustum cone side distribution is between 2mm ~ 5mm, and pitch-row is about 1mm.The coaxial loudspeaker of traditional structure can make tweeter horn serious to the acoustic reflection of frequency near 1000Hz, the acoustical behavior of woofer part is affected, frustum cone structure can change the reflection path of sound wave, reflected energy is decayed, the thickness of frustum cone side, the diameter range of aperture determines to play attenuation to the acoustic wave energy of which Frequency point together with pitch-row, derived by the series of theories being core with helmholtz resonance principle and draw, frustum cone side thickness is 3mm, hole diameter is between 2mm ~ 5mm, when pitch-row is 1mm, can the reflected energy of effective attenuation frequency near 1000Hz.
The beneficial effects of the utility model are, surface distributed the frustum cone structure of aperture, and the reflection path of the sound wave that bass cone is radiated changes, the energy of reflection attenuation ripple; Derive based on the series of theories being core with helmholtz resonance principle and draw, the size design of the thickness of round platform 3mm, the diameter of aperture 2mm ~ 5mm and 1mm pitch-row, can the reflected energy of effective attenuation frequency near 1000Hz.Thus, the utility model coaxial loudspeaker fidelity structure improves the Frequency Response of coaxial loudspeaker medium and low spectrum loudspeaker part, serves the effect of fidelity.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model coaxial loudspeaker fidelity structure;
Reference numeral: frame 1, magnetic circuit system 2, bass cone 3, tweeter horn 4, round platform 5.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Described embodiment is the utility model preferably execution mode; the utility model is not limited to described embodiment, all should be considered as belonging to protection range of the present utility model in the simple transformation done on creative work basis as those of ordinary skill.
As shown in Figure 1, coaxial loudspeaker fidelity structure, in coaxial loudspeaker, frame 1 is connected with magnetic circuit system 2, bass cone 3 is positioned at frame 1, tweeter horn 4 is positioned at bass cone 3, frame 1, bass cone 3 and tweeter horn 4 be flare shape all, round platform 5 is also comprised in coaxial loudspeaker, round platform 5 is the non-close structure be only made up of side, lateral thickness is that 3mm is left back, and the lower planes of round platform 5 overlaps with the lower planes of tweeter horn 4 respectively, and the side of round platform 5 is positioned between bass cone 3 and tweeter horn 4.The surperficial random distribution of round platform 5 aperture (not shown), and such structure can change the reflection path of the sound wave radiated by bass cone; Draw based on the theory deduction being core with helmholtz resonance principle, round platform 5 thickness is 3mm, and hole diameter is between 2mm ~ 5mm, and pitch-row is about 1mm, and such size design can the reflected energy of frequency of fadings near 1000Hz pointedly.
