Abstract
The utility model relates to a vibrating diaphragm all-opening type loudspeaker, which mainly comprises a supporting frame, the front part and the rear part which respectively contain an expanding opening and a magnetic element; a voice coil is arranged in the middle of the magnetic element; an elastic wave sheet is sheathed with and stuck to the voice coil; a vibrating diaphragm is arranged on the expanding opening on the supporting frame and the inner diameter thereof is adhered to the voice coil. The utility model is characterized in that the surface of the vibrating diaphragm is provided with no dangling edges but foaming gaskets are adhered between the lower part of the vibrating diaphragm and the expanding opening of the supporting frame. Therefore, the effective vibrating area of the vibrating diaphragm can be enlarged, the output sound pressure of the loudspeaker can be effectively improved; the foaming gaskets can also replace a conventional dangling edge for making equal auxiliary push-and-pull movement of the vibrating diaphragm to make the sounds of the loudspeaker normally output.
Description
The utility model relates to a kind of loudspeaker, refers to a kind of full-open type vibrating diaphragm loudspeaker especially.
The tradition horn structure is formed as shown in Figure 5, all link to each other between its bracing frame A1 and vibrating diaphragm A2 with outstanding limit A3, use except that obtain the good central location for vibrating diaphragm A2, the more important thing is when its arc design of mat can provide vibrating diaphragm A2 motion elastic telescopic freely, to guarantee normally speaking of loudspeaker.
Only the sound press size of loudspeaker output is to be directly proportional with vibrating diaphragm A2 size, for fear of exposed outstanding limit A3 design, habit formula horn structure shortcoming is: bracing frame A1 caliber size need approximate vibrating diaphragm A2 and add outstanding limit A3 again, so the actual effective area of its vibrating diaphragm A2 is littler many than the expansion bore of bracing frame A1, causes and make that relatively sound press output is limited.
Main purpose of the present utility model is, designs a kind ofly to exempt from outstanding limit, is bordering on the bracing frame bore and vibrating diaphragm can be expanded to maximum, to obtain the standard-sized sheet vibrating diaphragm loudspeaker of the highest output sound press.
For reaching above-mentioned purpose, the designer studies intensively, and a kind of full-open type vibrating diaphragm horn structure is designed in test improvement repeatedly, and it mainly comprises: a bracing frame, and the place ahead is installed with the element that is magnetic for enlarging a mouthful rear; One voice coil loudspeaker voice coil is put in the middle of magnetic element; One elastic wave sheet, glutinous with the voice coil loudspeaker voice coil cover; And a vibrating diaphragm, placing on bracing frame enlarges mouthful, internal diameter sticks mutually with voice coil loudspeaker voice coil; Outstanding limit is not established on this vibrating diaphragm surface, but sticks mutually in enlarging the foaming packing ring that is provided with between mouth with bracing frame under the vibrating diaphragm outer rim.
The utility model is commonly used loudspeaker and had the following advantages: 1. be the foaming packing ring owing to change outstanding limit, the effective vibration area that makes vibrating diaphragm more enlarged proximal is similar to and enlarges mouthful, makes loudspeaker output acoustic pressure effectively improve; 2. auxiliary vibrating diaphragm push-and-pull campaign is done to be equal in the outstanding limit of the alternative habit formula of foaming packing ring, makes loudspeaker sound sound get normally output.
Structure of the present utility model is formed and operation in order to further specify, conjunction with figs. explanation now as after;
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the stereo appearance figure of the utility model;
Fig. 3 is the three-dimensional exploded view of the utility model;
Fig. 4 is the combination view of another embodiment of the utility model;
Fig. 5 is the combination view of habit formula loudspeaker.
As shown in Figure 1 and Figure 2, set full-open type vibrating diaphragm loudspeaker in the present embodiment have a bracing frame 1, a voice coil loudspeaker voice coil 2, an elastic wave sheet 3, a vibrating diaphragm 4 and a foaming packing ring 5 is formed, a bracing frame 1 wherein, and the place ahead is established and is enlarged mouth 11 and the rear is installed with the element 12 that is magnetic; One voice coil loudspeaker voice coil 2 is put in the middle of magnetic element 12; One elastic wave sheet 3, glutinous with voice coil loudspeaker voice coil 2 covers; One vibrating diaphragm 4, external diameter place bracing frame to enlarge on the mouth 11, and internal diameter is glutinous mutually with voice coil loudspeaker voice coil 2.
Outstanding limit is not established on these vibrating diaphragm 4 surfaces.One foaming packing ring 5, it is beneath glutinous mutually with bracing frame expansion mouth 11 to be located at vibrating diaphragm 4.
Owing to establish in the foaming packing ring 5, so effective vibration area of vibrating diaphragm 4 can more be enlarged, be similar to and enlarge mouth 11, improve the output acoustic pressure when making the loudspeaker physical size not become effectively, and the outstanding limit of the also alternative habit formula of elasticity with foaming packing ring 5 institute tools own is done to be equal to the promotion campaign of assisting vibrating diaphragm 1, makes loudspeaker sound sound get normally output.
Please join concrete enforcement shown in Figure 1, for laying foaming packing ring 5, the expansion of this bracing frame 1 mouthful 11 sections can be established and be high outside and low outside L shaped, in between high bottom surface and be provided with a chase 111, these vibrating diaphragm 4 external diameter edges have a circle burnishing surface 41 and a reflexed ora terminalis 42, and add a limiting gasket 6 to link to each other with 1 of bracing frame in foaming packing ring 5 bottoms, these limiting gasket 6 sections can be established and be low inside and high outside anti-L shaped, cooperate the set reflexed ora terminalis 42 of vibrating diaphragm 4 outer rims, make assembling foaming in season packing ring 5 obtain the locating effect of the best.
Remove this, see also Fig. 4, this creation also can be leaned to one side to add a built-in outstanding limit 7 of circular arc with 1 of bracing frame at vibrating diaphragm 4 and be linked to each other, to assist vibrating diaphragm 4 centralized positionings more accurate.
