Description
Technical field
The utility model relates to electroacoustic device technical field, especially a kind of high-power high definition woofer.
Background technology
Loud speaker is a kind of energy transducer signal of telecommunication being changed into acoustical signal, audio frequency electric energy is again by after electromagnetism, piezoelectricity or electrostatic effect, make its cone or diaphragm vibration and with ambient air produce resonate (sympathetic response) thus and sound, its performance is good and bad very large on the impact of tonequality.
Traditional loud speaker is owing to limitting by structure, when the voice coil loudspeaker voice coil as vibration generation source is when carrying out up-down vibration, first disturbance is the air in inside loudspeakers space, thus generation clutter, the generation of clutter then can affect playback and the sound articulation of loud speaker, the muddy distortion of the sound that loud speaker is sent, especially for high-power woofer, the problem of audio distortions is then more outstanding.Meanwhile, the heat conduction of traditional loud speaker mostly depends on air transmitted heat radiation, and radiating effect is poor, not only easily increases the weight of the problem of audio distortions, and greatly reduces the power of loud speaker.
Therefore, proposing improvement project to existing woofer, is technical problem urgently to be resolved hurrily in current industry.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple and compact for structure, sound articulation and fidelity is high, the significant high-power high definition woofer of radiating effect.
To achieve these goals, the utility model adopts following technical scheme:
A kind of high-power high definition woofer, it comprises frame, voice coil loudspeaker voice coil, vibrating diaphragm assembly and the cross section T iron in " work " font, in the upper arm plate of described T iron, offer embedded hole around its armshaft, magnet ring is socketed with between the upper arm plate of described T iron and lower arm plate, be provided with the first aluminium cover between the armshaft of described magnet ring and T iron, described first aluminium puts, in axial direction offers the steam vent communicated with embedded hole;
Described frame seat is located in the upper arm plate of T iron, described vibrating diaphragm assembly is installed in frame, described voice coil loudspeaker voice coil is flush-mounted in embedded hole, and the bottom of described vibrating diaphragm assembly is offseted with the upper arm plate of T iron by one second aluminium cover, and the top of described voice coil loudspeaker voice coil is between the second aluminium cover and frame.
Preferably, described vibrating diaphragm assembly and the second aluminium are provided with acoustical cotton post between overlapping.
Preferably, described vibrating diaphragm assembly comprises vibrating diaphragm, locating branch slice and dust cap, the opening edge that the bottom of described vibrating diaphragm is fixed in frame by locating branch slice, edge, upper end is pressed on frame, described dust cap to be installed in vibrating diaphragm and acoustical cotton post is covered on the second aluminium and puts.
Preferably, the edge, upper end of described vibrating diaphragm is provided with flanging.
Preferably, the opening edge of described frame is along being also provided with EVA flanging.
Owing to have employed such scheme, the utility model by the first aluminium cover of arranging and the second aluminium cover by the air of inside loudspeakers smoothly and discharge rapidly, eliminates the condition producing clutter noise because of air agitation, the fidelity of lifting sound and definition; Also can dispel the heat rapidly to inside loudspeakers simultaneously, be conducive to the power promoting loud speaker; It is simple and compact for structure, has very strong practical value.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the high-power high definition woofer of the one that the utility model provides, it comprises frame 1, voice coil loudspeaker voice coil 2, vibrating diaphragm assembly and the cross section T iron 3 in " work " font be made up of aluminium material, embedded hole 4 is offered in the upper arm plate of T iron 3, around its armshaft, magnet ring 5 is socketed with between the upper arm plate and lower arm plate of T iron 3, between magnet ring 5 and the armshaft of T iron 3, be provided with the first aluminium overlap 6, on the first aluminium cover 6, in axial direction offer the steam vent 7 communicated with embedded hole 4; Meanwhile, frame 1 is located in the upper arm plate of T iron 3, and vibrating diaphragm assembly is installed in frame 1, and voice coil loudspeaker voice coil 2 is flush-mounted in embedded hole 4, and the bottom of vibrating diaphragm assembly is offseted with the upper arm plate of T iron 3 by one second aluminium cover 8, and the top of voice coil loudspeaker voice coil 2 is between the second aluminium cover 8 and frame 1.So, by the first aluminium added in T iron 3 and the hemi-closure space that formed between T iron 3 and magnet ring 5 overlap 6 and second aluminium overlap 8 can by air smoothly and discharge rapidly, eliminate the condition producing clutter noise because of air agitation, promote fidelity and the definition of sound; Also can realize inside loudspeakers dispel the heat rapidly by the first aluminium cover 6 of arranging and the second aluminium cover 8 simultaneously, improve conventional loudspeakers causes radiating effect difference problem because relying on air transmitted heat radiation, thus be conducive to the power promoting loud speaker.
For improving fidelity and the definition of loud speaker further, acoustical cotton post 9 is also provided with between vibrating diaphragm assembly and the second aluminium overlap 8, with this, utilize acoustical cotton post 9 not only can discharge by the air in hemi-closure space that formed between T iron 3 and vibrating diaphragm assembly fast, and the clutter and noise that produce because of inside loudspeakers air agitation can be absorbed further.
For optimizing the structure of whole loud speaker to greatest extent, ensure the effect of voice output, the vibrating diaphragm assembly of the present embodiment comprises vibrating diaphragm 10, locating branch slice 11 and dust cap 12 simultaneously; Wherein, the bottom of vibrating diaphragm 10 is by the opening edge that locating branch slice 11 is fixed in frame 1, edge, upper end is pressed on frame 1, and dust cap 12 to be then installed in vibrating diaphragm 10 and to be covered on by acoustical cotton post 9 on second aluminium cover 8.
Further, the edge, upper end of vibrating diaphragm 10 is provided with flanging 13.
In addition, for convenience of the Standard of whole loud speaker, be also provided with the EVA flanging 14 for parts such as pressing face shields on the opening edge edge of frame 1.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
