Abstract

The invention provides a kind of passive passive radiator loudspeaker system, it comprises loudspeaker unit and passive passive radiation body unit, described loudspeaker unit and the coaxial installation of passive passive radiation body unit.What the loudspeaker unit of passive radiator loudspeaker system provided by the invention and passive passive radiation body unit adopted is the coaxial manner sounding, can effectively avoid the phase difference of two unit sound; In addition, because loudspeaker unit and passive passive radiation body unit adopt coaxial manner to install, the erection space that can save sound box can make the sound box miniaturization, saves the space.

Description

A kind of passive radiator loudspeaker system
Technical field
The present invention relates to the loud speaker field, particularly a kind of passive radiator loudspeaker system.
Background technology
Passive radiator loudspeaker (claim empty cone audio amplifier again, affect the cone audio amplifier) is the playback system that grows up on the basis of phase inverted cabinet, it is made up of a loudspeaker unit and a passive radiation body unit (being commonly called as the sky cone), the passive radiation body unit replaces the position of the phase-reversing tube of phase inverted cabinet, the operation principle of passive radiator loudspeaker is to have utilized the spring action of air in the diffuser vibration rear cabinet to make the vibration of sky cone, form resonance with loud speaker, basic functional principle is similar with phase inverted cabinet.As shown in fig. 1, existing passive passive radiator loudspeaker (audio amplifier) system is installed separately loudspeaker unit 10 and passive passive radiation body unit 11 on audio amplifier baffle 12 and casing 13, according to Principles of Acoustics, such mounting means can cause the phase difference of two sound sources, because two sound sources begin sounding from different points, when arriving sound acceptance point (as people's ear or microphone), because there is path length difference in two point sound sources, thereby the phase difference that causes sound, and then cause the inhomogeneous increase of frequency response curve, increase the difficulty of debugging, also increased cost; And, because two sound sources are placed apart, increased the area of audio amplifier installation baffle 12, make that the volume of loud speaker is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of passive radiator loudspeaker system, be intended to solve that passive radiator loudspeaker exists sound source phase difference and the bigger defective of installation volume in the prior art.
Passive passive radiator loudspeaker system provided by the invention comprises loudspeaker unit and passive passive radiation body unit, described loudspeaker unit and the coaxial installation of passive passive radiation body unit.
More specifically, described loudspeaker unit is arranged in the passive passive radiation body unit.
More specifically, described loudspeaker unit and passive passive radiation body unit include a basin frame, the axis coinciding of above-mentioned two basin framves.
More specifically, described loudspeaker unit further comprises by locating branch slice and is arranged on vibrating diaphragm on the basin frame, is positioned at the train wheel bridge of basin frame below, is arranged on the lower plate between the voice coil loudspeaker voice coil, and is arranged on the magnet steel between train wheel bridge and the lower plate.
More specifically, the junction of described passive passive radiation body unit and loudspeaker unit is provided with flanging.
More specifically, form two rings between the basin frame of described passive passive radiation body unit and the flanging.
What the loudspeaker unit of passive radiator loudspeaker system provided by the invention and passive passive radiation body unit adopted is the coaxial manner sounding, can effectively avoid the phase difference of two unit sound; In addition, because loudspeaker unit and passive passive radiation body unit adopt coaxial manner to install, the erection space that can save sound box can make the sound box miniaturization, saves the space.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of the passive passive radiator loudspeaker system of prior art;
Fig. 2 is the cross-sectional view of the passive passive radiator loudspeaker system of the present invention;
Fig. 3 is the mounting structure schematic diagram of the passive passive radiator loudspeaker system of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Referring to the cross section view shown in Fig. 2, passive passive radiator loudspeaker system provided by the invention comprises loudspeaker unit 2 and passive passive radiation body unit 3, loudspeaker unit 2 and passive passive radiation body unit 3 coaxial installations, promptly loudspeaker unit 2 is arranged in the basin frame 34 of passive passive radiation body unit 3 (being different from parallel placement of the prior art).Loudspeaker unit 2 comprises basin frame 22 (its central shaft with basin frame 34 overlaps), be arranged on vibrating diaphragm 20 on the basin frame 22 by locating branch slice 23, be positioned at the train wheel bridge 26 of basin frame 22 belows, be arranged on the lower plate 25 (being commonly called as T iron) between the voice coil loudspeaker voice coil 24, locating branch slice 23 location voice coil loudspeaker voice coils 24.Be arranged on the magnet steel 27 between train wheel bridge 26 and the lower plate 25.Passive passive radiation body unit 3 is provided with flanging 32 with the junction of loudspeaker unit 2, and the outside of basin frame 34 also is provided with flanging 31, and the effect that forms 33, two rings 33 of two rings between basin frame 34 and the flanging 32 provides the restoring force of passive radiant body.
In conjunction with referring to shown in Fig. 3, when being installed in passive passive radiator loudspeaker system provided by the invention on the casing 4, flanging 31 is arranged between passive passive radiator loudspeaker system and the casing 4.Compare with existing passive passive radiation loud speaker,, can effectively avoid the phase difference of two unit sound because loudspeaker unit of the present invention 2 and 3 employings of passive passive radiation body unit is the coaxial manner sounding; In addition, because loudspeaker unit 2 adopts coaxial manner to install with passive passive radiation body unit 3, the erection space that can save sound box can make the sound box miniaturization, saves the space.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the protection range of claim of the present invention.
